Abstract: A slide structure having an elongated slide body having a pair of outwardly convergent continuous slide surfaces at each side thereof which are supported within longitudinally spaced pairs of vee blocks which vee blocks are carried by a base member. The vee blocks at each side of the slide body are pivotable with the vee blocks at one side being selectively biased to provide a selectable preload between the vee blocks and the slide body.

Abstract: A bicycle chain cleaning or lubricating device and method adapted for cleaning or lubricating bicycle chains in place without need for their removal and replacement. The device comprises a receptacle for enclosing a portion of a bicycle chain to be cleaned or lubricated and for containing a quantity of solvent or lubricant and a mating cover for the receptacle. The cover contains at least one rotatable sprocket brush having spaced-apart bristle tufts on its periphery and sized to fit closely into adjacent spaces in the bicycle chain, so that the movement of the chain through the device causes the chain and central brush to dip into the solvent or lubricant and then enter the spaces of the chain so as to clean or lubricate the chain as it is passed through the device. The receptacle and cover of the device are held together by suitable retainer means, such as a wire clamp located at the central portion of the device casing.
Abstract: A moving substrate material such as a web of paper, paperboard, film, or other substance is covered with a coating by propelling a coating material onto a deflector bar positioned near the substrate material. The deflector bar is configured to deflect the coating material toward the moving web in a continuous, free standing, smooth jet curtain of coating material. The coating on the web is free of skips, scratches, and other imperfections. In one embodiment, propulsion of the coating material toward the bar is accomplished by rotating a drum, or applicator roll, through the coating material. The surface of the drum or roll carries the material to the deflector bar at a speed and in a sufficient quantity to cause the material to be deflected by the bar in a continuous free standing curtain toward the paper web.
Abstract: A tape cartridge for use in the reproduction of sound recordings on a tape is characterized by a brake mechanism which moves in a linear direction toward and away from the rotating reel and hub which carry the tape. The brake mechanism consists of a unitary structure which is guided between two upstanding walls within the cartridge and a spring which is operatively connected to the unitary structure and urges it toward the reel. A pawl like projecting member is positioned on the outer periphery of the unitary structure and is designed to engage any one of the plurality of openings in the reel thereby preventing rotation of the reel. Disengagement of the pawl member from the reel enables rotation of the reel. The linear motion of the unitary brake structure enables the cartridge to be properly aligned when positioned within the tape recorder machine resulting in an even pressure pad contact and tape tracking.
Abstract: A facsimile reproduction system is disclosed. The system utilizes a laser beam at the transmission station to scan across an image to be reproduced through an acousto-optic modulator (AOM) cell. The laser beam is reflected off the image onto photo detector cells to generate electrical signals analogous to tonal variation in the image. A laser beam at the receiver station is also provided to sensitize a sheet of sensitized paper to produce a facsimile of the image. The intensity of the receiving station laser beam is modulated in accordance with the photo detector electrical signals by applying the signals to an rf carrier which then is applied to an AOM cell positioned between the laser and sensitized paper.
