Abstract: A pedestal assembly for use in a railroad vehicle having a journal box which slides vertically with respect to the pedestal assembly, said assembly including a pedestal liner consisting of elastomer having a wear face and a non-wear face, said wear face confronting the journal box, a pedestal liner insert consisting of an elastomer having a first and second side, the first side confronting the non-wear face of the pedestal liner and the second side confronting the pedestal leg, a plurality of spacing washers and a means attaching said pedestal liner and pedestal liner insert to said pedestal leg through said spacing washers and a process for producing the pedestal liner and the pedestal liner insert by injection molding.

Abstract: By employing several independent variable compensating mechanisms between a positive displacement liquid meter unit and two output registers, which mechanisms are responsive to physical changes in the liquid passing through the meter unit, accurate readings in both gallons and pounds of liquid passing through the meter can be read directly from the registers. Obviously the registers can be calibrated in the metric equivalents.

Abstract: The ability to control butterfly valves is greatly enhanced with a geared hand wheel having concentrically contained therein a pair of flat spur gears with at least one tooth difference and a pinion gear meshing with both of these gears with the pinion carried by the hand wheel in a planetary manner about these gears whereby a mechanical advantage is achieved as the spur gears are caused to rotate relative to one another by rotation of the hand wheel to control the valve shaft of the butterfly valve.

Abstract: A simple, economical valve unit for dispensing liquids and the like includes a cylindrical bell with an inwardly directed conical surface at one end and an outwardly directed radial flange at its opposite end with a central aperture in the conical surface and an open-ended buoyancy cylinder having a conical crown terminating in a projecting shaft received in the bell so said shaft extends through the aperture, and a cap seal attached to the distal end of the shaft whereby when the cylinder moves out of said bell, the cap seal will contact the conical surface in a sealing relationship, and when the cylinder moves into the bell, its conical surface will sealingly close the central aperture. The buoyancy cylinder is longer in axial length than said bell, so its projecting end can be engaged by a cap placed on a bottle in which the unit is installed to axially force its conical crown into the central aperture to prevent leakage of the liquid contents during shipment of the bottle in which the unit is installed.

Abstract: A controller for a motor or like electrical equipment. A thyristor in series with a power conductor that feeds the equipment and a control circuit for activating the gate terminal of the thyristor in accordance with the operating conditions of the equipment. The control circuit includes a transformer having a secondary winding connected to the gate terminal and means for varying the current flow in the secondary winding according to load demands. A three phase system having a thyristor in each conductor and a transformer secondary winding for each thyristor, which windings are on a common core.

Abstract: A precision hand-held label imprinter and dispenser includes a compact case or frame with a projecting handle and an applicator roller located remote therefrom, together with a dialable imprinter and platen assembly arranged so that a trigger lever associated with the handle may be manually acutated in one direction to imprint label stock (tape) by driving the platen across an imprinter in an engaged condition to force the printing medium and label stock thereagainst and operates in the opposite direction to separate the imprinter and platen and to simultaneously advance the printing medium and to advance the printed label stock to the applicator roller. Through a series of connected drive elements with the trigger lever, the device times the several functions so that accurate reproductions with high resolution of the dialed imprint information on each label is assured.

Abstract: A film strip controller for exposed and developed photographic roll film adopted to be used with a photographic printing apparatus employing a roll film strip transport drive using slip clutches, includes a magnetic brake assembly responsive to signals generated as a result of varying light intensity incident upon a plurality of photosensitive detectors. The brake assembly stops the roll film being transported through the controller with each negative image on the film strip in proper registration and locates the negative in the proper plane so the shutter of the associated photographic printing apparatus can be operated to expose a positive print of the negative. Operation of the shutter may release the brake of the controller allowing the film to continue to move through the film strip controller until stopped by the brake means for the next negative.
