Abstract: This invention relates to an improved injection molding filter assembly to be located between the molding machine and the mold. The assembly has an elongated inner torpedo member with a generally cylindrical outer surface which is centrally located in a passage through a hollow outer member. The passage is defined by a generally cylindrical inner wall which is interrupted by an even number of inwardly opening longitudinally extending channels. Inlet channels extending from the inlet of the assembly and dead ending adjacent the outlet alternate with outlet channels extending from the outlet of the assembly and dead ending adjacent the inlet. Uniform width elongated filtering slits are thus formed between the outer surface of the torpedo member and the lands between the inlet and outlet channels. The melt flows into the inlet channels, through the adjacent filtering slits, and out the outlet channels.

The inner core portion is formed of a high strength material such as a beryllium nickel alloy and the outer shell portion is formed of a highly conductive material such as a beryllium copper alloy. The coils of the heating element are separated from each other and threaded in the opposite direction to the helical ridge on the outer surface of the core portion.

Abstract: The invention comprises a rectangular plastic sheet which may be folded about living hinges to provide a container for holding coins and the like. The sheet is made of polypropylene or other suitable plastic material which has good living hinge qualities in thin sections. The preferred embodiment consists of three V-shaped units separated by two living hinges, which units when folded form a regular hexagonally cross-sectioned cylinder. Ledging may be provided on the end of the sheet so that when folded the ledging at least partially closes the otherwise open ends of the cylinder. A locking mechanism comprising an upwardly extending lip on a side edge of the sheet which engages a hollow behind and beneath a downwardly extending lip on the other side edge is provided. By forcing contact by the coins against the container walls when the container is closed the material is tightened against the coins and the locking mechanism becomes more tightly engaged, securing against accidental opening.

Abstract: This invention relates to an improved suspension system for filing computer paper vertically in a file drawer or cabinet. A bundle of a desired number of sheets of paper may be filed using a system having a pair of assemblies, each of which has two members to engage the upper corners of the sheets of paper. The first member of each assembly has a flat panel-like portion which extends at an upper corner thereof to define a downwardly open hook and three vertically spaced horizontally extending prongs. The second member is flat and rectangular shaped and has three vertically spaced apertures which mate to receive the three prongs therethrough. The prongs of each first member are inserted through the upper three holes along one side of the computer paper, and the second member is then located on the prongs. This is repeated on the other side with the other assembly to hold the sheets of paper in a single bundle.

Abstract: This invention relates to an improved open ended package or container which is formed from a one piece blank to hold a pair of light bulbs in an end to end relationship. The bulbs are spaced a desired distance from the open ends of the container and longitudinally retained in both directions as well as prevented from contacting each other in order to avoid breakage during shipping and storing. The one piece cardboard blank is folded and secured by adhesive strips at each end to form a rectangular sleeve having a top, bottom, two sides, two open ends, and a partition element. The partition element is provided with cut lines and fold lines to form two separating portions and two retaining portions, all of which extend across the container between the top and bottom, each in a different plane parallel to the two sides.

Abstract: This invention relates to a continuous flow gravitational separator having inclined membrane baffles therein which separates solid particles and also foam from a suspension liquid. A rectangular membrane assembly with a plurality of parallel inclined flexible membranes is received in a cylindrical tank, thereby defining four vertically extending arc-shaped compartments or segments between the membrane assembly and the wall of the tank. The tank has a funnel shaped bottom solids outlet and oppositely located inflow and outflow segments are connected respectively to the liquid inlet and outlet. The liquid flow across the inclined compartments between the membranes is distributed evenly by vertical inflow and outflow distributor plates. The solid particles settle along the inclined membranes to a solids receiving segment, while the foam rises along the membranes to an oppositely located foam receiving segment.

Abstract: A novel apparatus for the measurement of color of a sample which comprises an illumination means to illuminate the sample, an electro-optical sensing head to receive the light from the illuminated sample and to output electronic signals and an electronic processing unit adapted to process the signals. The system uses, in the preferred embodiment, a moving spatial filter to modulate a spectrum and a masking means to selectively mask the light from the modulated spectrum. A reference optical path and reference light signals are produced for subsequent processing with the light from the sample, corrected for any errors produced and processed in an analogue electronic unit to produce the tristimulus values X, Y, Z and the chromaticity coordinates x, y of the sample with respect to CIE standards for luminance and chromaticity values.

Abstract: This invention relates to an improved golf ball retriever of the type which may be lowered directly over the ball. The retriever has a telescopic handle for reaching into water hazards and the like. The handle is pivotally connected to a body member which has a pair of lower forwardly extending curved arms and a retaining ring pivotally connected at its rear to the body member at a point above the plane of the curved arms. Thus the retaining ring normally slopes forwardly downward and rests on the ends of the curved arms. The ring is slightly larger in diameter than a golf ball and when the retriever is lowered over a golf ball, the ring pivots slightly upward to increase the effective size of the opening between it and the curved arms to allow the ball to pass therethrough. When it has, the ring drops down past the outside of the ball, and the retriever is then lifted upwards with the ball engaged by the ring and the curved arms.
