Abstract: A plain bearing comprising a steel backing, a sintered bronze interlayer and a lining of a material consisting of polyether ether ketone, polytetrafluoroethylene, graphite and bronze.

Abstract: The specification discloses a polymer blend comprising 25 to 35% rubber dispersed in a laminar, network fashion in a rigid polymer phase. This is achieved by using a low molecular weight elastomer (70,000 to 100,000 weight average molecular weight) having 25 to 44% styrene and a melt flow rate of 8 to 15 grams per 10 minutes. This polymer blend is especially adapted for injection molding and products injection molded therefrom have a high gloss and excellent strength and toughness. The polymer blend is especially suited for injection molding and yields a high gloss, strong injection molded product.

Abstract: An alignment gauge and method of use for aligning a scriber tool, the alignment gauge including a base and a pair of upstanding, at least semi-transparent side walls that extend forward of the front edge of the base. A pair of sight lines extend along the inside surfaces of the side walls in a common plane with the base front edge, and a clamp holds the guide post of the scriber in abutment with the base front edge while the scribing needle is visually aligned with the sight lines.

Abstract: An arch structure for an earth sheltered building includes a plurality of curved wood panel sections arranged in tandem and in a plurality of adjacent rows. The sections are joined adhesively and define an arch resting on a foundation of footings. Each of the panel sections includes side members joined to end members and ribs extending between the side members and between the end members. Joined to the members are top and bottom skins which enclose the panel and in conjunction with the ribs define a plurality of compartments. Insulation material is disposed within the compartments. At least one of the skins is offset on the side members to define male and female portions which are joined with panel sections in adjacent rows. The panels are fabricated from wood. After assembling into the arch form, the panels are covered with an exterior sheathing which is pressure treated and waterproofed. End walls are attached to the arch section, and the structure is covered with earth.

Abstract: For a vehicle conventionally having at least a pair of laterally separated rear lights, a brake switch operated by the brake pedal of the vehicle for normally causing illumination of both lights and a turn signal switch and flasher combination for intermittently operating one of the pair of rear lights to indicate an intended direction of turning, a system for controlling the rear lights of the vehicle so that, upon actuation of the brakes of the vehicle after the turn signal switch is operated to indicate the direction of an intended turn by causing intermittent illumination of one of the rear lights, the other rear light is continuously illuminated until the turn signal switch is turned off.

Abstract: The specification discloses a sandwiched reinforced slatboard assembly including a baseboard, a plurality of C-shaped reinforcing channels arranged on the baseboard, and a plurality of T-shaped slats secured to the baseboard to entrap the channels therebetween. Optionally, the C-shaped channels are omitted and the slats are secured to the baseboard using a colored adhesive which is visible between the slats to provide a decorative appearance. Also disclosed is a modified assembly wherein decor strips are removably received within the slots, and wherein the slots are configured to retain the strips against the back wall of the slot.

Abstract: The specification discloses a method for freeze coagulating polymeric material in which the freezing surface is coated with a thin film of ice to facilitate separation of the coagulated material from the freezing surface without the need for mechanical scraping.

Abstract: Means are provided to introduce pressurized fluid from a source into an intermittently rotated machine tool such as a chuck while the tool is stationary. The means includes a stationary annular shell surrounding a portion of the tool and radially spaced a short distance from the surface of the tool. The inside of the shell has a channel which seats an annular flexible U-shaped seal the radially outer ends of the legs of which are rigidly secured to the shell. The inner face of the seal is a web having a relatively stiff center band which, under fluid pressure is forced to shift into contact with the surface of the tool to form a seal on each side of a groove in the tool's surface. A restricted opening permits fluid from the inside of the seal to be introduced into the groove to supply the tool.

Abstract: A meat cutting device for cutting long rolls of meat into shorter chunks includes means for conveying long rolls one after another against a plurality of blades, each having converging sharpened edges forming a sharp point. The blades are positioned parallel to one another across and above the path of travel of the rolls and are located so that as a roll is conveyed into the blades, the blade points will pierce through the skin of the roll before the sharpened edges begin to slice through the roll. Preferably the conveyor means includes a table on which support cradles are moved and the blades are positioned above the table with the blade points located above the table so that central axis of the roll is located under the points as the roll is moved through the blades.

Abstract: The specification discloses a pool wall assembly including first and second pool wall panels and a brace supporting the panels. Structure is included for securing the brace to only the first panel so that the first panel and brace may be aligned together prior to the securement of the second panel. Structure is also included for securing the second panel to at least one of the first panel and the brace. An anchor assembly secures the brace in position. The anchor assembly includes a stake which extends through and slidingly engages the brace and a wedge, telescopically received in the stake, which can be moved with respect to the stake into forcible engagement with the brace to maintain the brace in position. Each panel includes an integral bead extending from the lower portion of its face to define the line to which the pool side wall overlap extends. Also disclosed is a method of erecting a pool wall using the structure disclosed.
