LBJ's education proposal already running into trouble

President Johnson's proposals for fed­eral aid to higher education, which he outlined in a special message to Con­gress last week, have already run into a little trouble. Surprisingly, the sour comments emanating from Republi­can members of the House Education Committee were aimed at the Presi­dent's proposal to cut spending for construction of college buildings.

In his message, President Johnson said, "We must carefully set our pri­orities. To meet our urgent needs within a stringent overall budget, sev­eral programs must be reduced or de­ferred. We can reduce expenditures on construction of facilities and the purchase of equipment. But, many of our urgent educational programs which directly affect the young people of America cannot be deferred."

The President proposes to cut spending for the college construction grant program by $75 million: $225 million in fiscal 1969 compared with $300 million in 1968.

As hearings opened on the propos­als, Rep. Albert Quie (R.-Minn.), sec­ond-ranking Republican on the House Education Committee, challenged U.S. Commissioner of Education Harold Howe on the cuts in con­struction funds. Pointing to the steady increase in college enrollments, Rep. Quie asked, "At the rate of re­duction that the President has made in funds for college facilities, what is he going to provide for professors and students to work in?"

Commissioner Howe's answer: "You have to recognize that the Presi­dent took the position that this is a tight budget year and calls for priori­ties. It is a clear response to the call of Congress for this kind of action." As hearings proceed, it probably will become apparent that voluntary cuts in spending will not be restored.

Major points in the President's plans for higher education include:

• Strengthening the guaranteed stu­dent loan program by meeting the ad­ministrative costs of the banks who make the loans.

• Unification and simplification of student aid programs so colleges have flexibility to tailor aid plans to the needs of individual students.

• Several modest new programs of tutoring, counseling, and the like.

The President also wants Congress to approve a Networks for Knowledge Program under which schools will pool faculties, equipment, and facili­ties; an increase in federal payments to graduate schools; a new program to strengthen "those graduate schools with a clear potential for higher qual­ity"; and an increase in government-sponsored research activity in univer­sities.

For elementary and secondary schools President Johnson proposes modest increases in current aid pro­grams and several new ones.

The actual cost of the President's proposals is not clear as of now. Many of the programs have no price tags at all. However, the 1969 bud­get forecasts educational spending of $4.7 billion, an increase of $158 mil­lion over the present level.

Goodyear develops adhesive for reinforced polyester

Goodyear Chemical has developed an adhesive system designed especially for fastening glass-fiber-reinforced pol­yester (FRP) to itself and to metal. At the Society of the Plastics Indus­try meeting in Washington, D.C., last week, Goodyear's Samuel M. Berko-witz said the new adhesive, a modified polyurethane, can reduce by more than 20% the cost of fabricating FRP components for two reasons: expen­sive surface preparation steps such as shot blasting are eliminated, and the system lends itself to mechanized dis­pensing and joining.

The system is already being used in significant production applications. For example, International Harvester is using it on a production line that assembles 35 FRP truck cabs per day, and Molded Fiber Glass Co. is using it in some boat assembly applications. Volume applications in passenger au­tos, for hood and rear-deck assembly, are imminent, Mr. Berkowitz says.

Adhesives are used almost exclu­sively for joining FRP components because mechanical fasteners such as bolts or rivets create highly localized stresses. The two types of adhesives usually used for FRP are polyesters and epoxies. Polyesters are favored in volume applications because of lower prices. But in addition to the need for extensive surface preparation and the unsuitability for mechanized bonding procedures, both these types of adhesives have other drawbacks, such as being brittle and having a ten­dency to "bond burn." Bond burn oc­curs when the adhesive curing reac­tion generates enough heat to distort

the surface of the polyester substrate. The new Goodyear adhesive cures

below 150° F. and thus does not bond burn. In addition, the bond is highly elastomeric and can absorb shocks and stresses.

The Goodyear adhesive is a two-component system consisting of the urethane base adhesive and three dif­ferent proprietary curing agents. By selecting the appropriate curing agents the cure time required to achieve 100-p.s.i. bond strength can be varied from almost instantaneous (using heat) to about 10 minutes at room temperature.

In addition, either nonsag or self-leveling characteristics can be ob­tained. A completely mechanized dis­pensing system using heated position­ing fixtures can produce a bonded part in less than two minutes, com­pared with about 15 minutes using other methods, says Mr. Berkowitz.

Base cost of the new adhesive is about the same as that of epoxies. But cost studies show that elimination of the shot blasting step and the rapid cycle times result in lower costs per bond than with conventional adhe­sives.

CUNY plans ghetto-oriented community college in Brooklyn

The City University of New York (CUNY) and the city's board of higher education have designated the sprawling ghetto neighborhood of Brooklyn's Bedford-Stuyvesant as the location for an experimental two-year community college. The proposed school will be CUNY's seventh com­munity college but the first planned for the underprivileged high school graduates of an area that could have
