US Patent:

47073179, Nov 17, 1987

Filed:

Feb 28, 1986

Appl. No.:

6/835086

Inventors:

Joseph N. Epel - Southfield MI
John J. Morse - Rochester MI
Terry N. Trebilcock - Southgate MI

International Classification:

B29B 1510
B29C 4318

US Classification:

264136

Abstract:

A non-metallic leaf spring in which a unitary body member is made up of strands of glass fibers distributed in a matrix of polymerized epoxy resin. The spring is provided with end fittings and a mounting assembly intermediate the ends of the spring by which the spring can be mounted between suspended and unsuspended structures without causing stress concentrations at the non-metallic spring. The method and apparatus by which the spring is manufactured casues strands of fiber to be distributed throughout the spring at a substantially uniform density throughout the longitudinal length of the spring.

International Classification:

C08K 322
C08K 520

US Classification:

260 40R

Abstract:

The invention relates to improving the viscosity temperature dependence of a maturated moldable unsaturated polyester resin system, by utilizing a dual thickening system consisting of an oxide or hydroxide of magnesium or calcium and a polyisocyanate, which dual thickening system provides a greatly improved viscosity index, i. e. , less viscosity decrease with increase in temperature, thereby providing substantial advantages upon being subjected to temperature increases such as are encountered in molding.

Horst F. Mach - Toledo OH

Assignee:

The Budd Company - Troy MI

International Classification:

B29G 202
B29G 100

US Classification:

425405R

Abstract:

Apparatus is disclosed for compression molding a part from a charge having a curable resin therein. Provision is made for defining a vacuum chamber surrounding the mold cavity when the upper and lower dies are brought to a partially closed position. The vacuum chamber includes a vertically movable ring surrounding the upper die which is urged into sealing engagement with a surface surrounding the lower die. The space between the ring and the upper die is sealed with a flexible diaphragm having an inner edge rigidly attached to the upper die and an outer periphery rigidly attached to the ring member thereby permitting relative vertical movement between the ring and die. The mold cavity is rapidly evacuated and then the upper die is brought into a fully closed position while the resin cures.

US Classification:

473490

Abstract:

A system and method for handicapping a ball game such as tennis or volleyball between opponents of lesser and greater skills, by varying or moving at least one of the parameters of the court on which the game is played, a sufficient amount to balance the disparity in such skills. The parameters described are the net, and court boundary lines which may be defined by electric luminescent tape embedded in, or fastened to, the surface of the court floor in parallel spaced lines which selectively can be lit to define the desired boundary, or, may be defined by projected lines on or adjacent to the floor from narrow beam or laser beam projectors capable of projecting lines at desired locations either from overhead or at floor level.

Joseph N. Epel - Southfield MI

Assignee:

Shell Oil Company - Houston TX

International Classification:

B29C 4556
B29C 3940

US Classification:

264257

Abstract:

A method and apparatus are disclosed for the reduction of mold cycle time. A deflatable member is positioned flush with the surface of a mold in an opening defined downwardly therein. Prior to flow of a resin or other hardenable liquid within the mold, the deflatable member is deflated so as to define a resin flow channel across selected portions of the mold surface. Prior to hardening of the hardenable liquid within the mold, the deflatable member is inflated so as to become flush with the surface of the mold so as to yield an article of manufacture having a relatively planar surface.

International Classification:

B26B 2300

US Classification:

145 2R

Abstract:

A swingable impact tool and a method of making it wherein the tool has a metal head fastened both chemically and mechanically to a handle made of a composite of materials including a pultrusion of fiberglass filaments in a matrix of polymerized thermosetting resin covered by elastomeric urethane form which protects the core member from impact loads and absorbs the transfer of shock loads to the hands of the user. Metal or plastic members are used to reinforce critical areas of the handle adjacent the head and the stem member disposed within the socket in the head.

International Classification:

B29B 1102
B26D 1147

US Classification:

264115

Abstract:

A method and apparatus for making a charge used in molding a fiber reinforced part. Continuous strands of fibers are impregnated with resin and then cut into segments of predetermined lengths. The segments are collected so that the resin impregnated fiber segments are piled together to form the charge. In one embodiment, the fibers are collected in a controlled manner to provide preselected fiber orientation for the molded part. Also a cutter mechanism is provided for cutting resin impregnated fiber strands pulled over a first rotating drum.
