This project is part of a broad program (ref CTCM 34282, dated 6 May 1952) for the development of a family of antlvehicular land mine fuzes. The fuze is pressure operated and will explode an AT mine under the area of a tank. It uses two extended pneumatic tubes; compression of these, one by each tank tread, results in functioning of the electric detonator. Other uses for the fuze, such ss in booby-trspping, are readily visualized.

Phase schedule changed since

a. The remaining fu- ;3 of this lot have been received, completing delivery of the 200 fuzes. Tests of the function switches indicate that some switch contacts are contaminated by foreign matter, probably epidermal oils. Measurements hsve slso disclosed a disturbing decay uf battery open circuit voltage, About 10X of the ISO fuzes checked exhibit voltages less than half the nominal 180 volts. While the lower limit for operation is about 75 vclts, further decay seems probable in those samples.

b. Watchmakere assembling the Elgin-made parts to produce timers for this fuse have encountered difficulties In producing acceptable timers, Judged by our arbitrary requirement to run through the complete arming cycle ten consecutive tlmee without Any failure. Wear on the timer during this testing la negligible. The difficulties arise primarily from an uneven torque delivered to the pin le.er eacapemant, which can run only when driven by a finite range of torques. Additional work on the #1151 timer for this fuze has pinpointed the etajor cauae of torque loss with consequent clock stoppage. The screwdriver type coupling between movement drive pinion and movement drive stud was re- placed with a rigid one-piece pinion In eight timers typlc*1 of those which previously operated erratically. With the new pinion, these eight operated aatiafactorily.

C. Ten fuzes were tested at APG for resistance to sympathetic detons- tion and function agalnat a tank. Ail fuzes were assembled to Inert-loaded T29 mines, with externally connected heat squibs to indicate fuze function.

Six rounds '»«re burled with the top of the fuze 2 In. below the aurfece. with tubea burleo at a nominal 1 in. depth. The remaining four were placed on the aurfaca, with tubea alao on the surface. Twelve pounds of coapoaitlon C^, molded in an ice cream carton, was burled 4 In. below the surface and fired to simulate a mine detonation. All the heat squibs were Inspected to confirm non-function, then an M47 tank paased over the burled fuzes while those heat squibs were observed for function. The surface empleced rounds were sti- muleted for function by flattening about l-ln. of the tubes by hand.

Using four charges, there were 40 opportunities for mal- function and 40 subsequent opportunities for function. Those fuzes placed above ground reelated aympathetic detonation and functioned properly 16 times out of 16 opportunities, et distances ranging from 8 to 32 feet from the charge. Thoae empleced normelly reelated sympathetic detonation 24 tlmee and functioned properly 23 times at distences ranging from 6 to 48 feet. The non-function occurred efter the lest charge was fired. This fuze was later examined In the laboratory and found functionable, therefore the cause of failure remains unknown.

d. Two fuzes were tested for function against light wheeled vehicles inside the DOPL compound area. Using a 3160 pound carryall in hard dry soil, there were 13 functions out of 24 opportunities. Thirty-nine overpassages were made with o 3349 pound pickup truck, with twenty-four functions.

e. Ten fuses are currently undergoing aummer environmental field teste at Yuma Teat Station

It utilizes a combination of vibratlora 1 and magnetic influences to function the mine when the target Is In a vulnerable position. The fuze la the same as the TI22I4EI except that it incorporates (a) Improved sensing elements which can better recognize desired targets and reject unwanted targets or countermeasurea, and (b) aelectable self-sterlllza- tion. (The self-sterilizing mechanism developed for this fuze will also be used in ri217E3, T1233, T1235, and possibly other fuzes.)

(b) Preliminary data Indicate fairly close agreement between design and performance characteristics. Some further adjustment probably will be necessary.

(c) Trembler switches have been made for the 25 fuzes. These new type 3-termlnal transfer switches will replace the old type i|~reed switches used In the TI22I4EI fuze. As planned, these swltohea will be sensitive to horizontal motion rather than vertical motion as In previous models.

(d) Bids were received from four contractors for tve production of 20 sterilizer followup units of the cutaway gear type. After evaluation of the bids, a contract was awarded to Westcloit, a division of General Time Corporation.

(e) A second model of the timer unit Incorporating the new balance wheel contacting system was constructed at DOPL and Is operating very satisfactorily. This model does not Include the pulse generating components.

(f) Modifications were made on the three Hamilton timers, and two of the three have been running for more than a month.

(g) Satisfactory methods were demonstrated for obtaining firing capacitor voltage from the protective circuit on the clock contacts for fall-safe sterilizer operation. These circuits are adaptable to both high voltage (carbon bridge) and low voltage (wire bridge) detonators.

Several types of tricger circuits wore tested separately and also a number of passive transistors and semiconductor diodes of appropriate types for fuze use. Results are reported under Project TS1-210.


PLANNED OBJECTIVES FOR NEXT PERIOD a. Construct and test six new prototype fuzes with manual zeroing. b. Try use of voltage sensitive aluminum oxide switch in place of

transistor blocking oscillator for firing detonator. c. Continue study of self-zeroing system. d. Continue work on interim technical report.

This unit uses Ki ß-terminal DOPL trembler switch to excite the ringing oscillator tn a balanced phase manner to provide equal sensitivity for signatures of either polarity. The translator used to charge the firing capacitor Is now connected In an "Inverted" manner to give better switch action In the cutoff or unexclted condition.

c. Continued study of the magnetic sensing element Indicates that molybdenum permalloy strips ore or two mils thick give greatest uniformity between units, and lowest null output.

Thla fuze Is part of a broad program (ref OTCM 3A282, dated 6 May 1952) for the dev«lopment of a family of antIvehlcular land mine fuzes. It Identi- fies the target by detecting changes In the gamma radiation Intensity b«ck- scattered from a vehicle to a fuze after emission from a iaoderate Intensity radioactive source nearby. Detection la accomplished with a scintillation crystal and photomultIpller tube with associated circuitry. A second influence, ground vibration, must als-j be present for fuze function.

These fuzes outy not contain solid electrolyte batteries, since at this time, there are no batteries of this type available that will meet appli- cable military standaris. Parallel efforts are being carried out at DOFL and Tracerlab on a transistor oscillator high voltage power supply (energised by mercury cells) for this fuze.

b. Work continues on the new approach to detection of low level gamma radiation as applied to this fuze. While the method is theoretically possible, experimental difficulties have been encountered in the high frequency, high Impedance electrical circuit. Negotiations with RCA have been atarted for the construction of two special vacuum phototubes for this project.

c. Work continues on the preparation of the Interim Summary Technical Report, which is about two-thirds finished.

d. Results of the tests on the two T12 35 fuzes exposed in Operation Hardtack are a part of Project TS1-210 and are reported therein.
