Abstract: An adjustable pressure control device for hydraulic brake system which reduces pressure surges during braking to decrease wheel slip at one or more wheels during braking. The device has replaceable internal elements which may be combined to tailor the damping response of the device to a specified application.

Abstract: A brake block for automotive drum brake systems having a visible wear indicator indicating the remaining usable thickness of the brake block. The wear indicator may be molded or machined into the side of the brake block and also may indicate where the tops of the fasteners for the brake block are located when fasteners are used to affix the brake block to a backing plate.

Abstract: The invention relates to a device for guiding a moving body (1) along a tensioned cable (4) attached at intervals to a building facade (3) and at a given distance therefrom. It comprises a pivoting device (7) formed by a pair of stars (8) parallel, coaxial and integral with one another, the points (9) of which face one another, pivoting about an axis perpendicular to the cable axis (4), the axis of the pair of stars (8) being rotationally integral with the structure of the guided moving body (1).

Abstract: A gas arc metal welding gun has a handle which may be rotated freely with respect to a conduit containing a current transfer wire and a gas tube and with respect to an adapter and tip assembly.

Abstract: A high torque low speed motor has a nutating assembly driven by a hydraulic or an electric actuator. The nutator assembly drivingly connects to an output shaft through a gear train. Because of a difference in the number of teeth between a gear on the output shaft and a gear on the nutating assembly, the output shaft is driven at a differential ratio as the nutator assembly is driven.

Abstract: A rail brace assembly for buttressing the head of a traffic rail as a rail brace with upper and lower slanted surfaces adapted to engage corresponding surfaces on a traffic rail. The rail brace assembly includes a bearing insert having a main body portion with a top surface adapted to engage a resilient fastener, a bottom surface adapted to engage a rail brace and a downwardly depending leg adapted to be received in an opening defined in a brace plate which engages a bearing surface on the rail brace and a bearing surface on the brace plate to cause lateral loads applied to the rail brace on the bearing insert to be resisted by the brace plate. Also, the rail brace assembly includes a shoulder secured to the top surface of a brace plate adapted to receive one leg of a resilient fastener and a resilient fastener having one leg adapted to be inserted into a shoulder opening and another leg adapted to engage the top surface of a bearing insert.

Abstract: A portable basketball goal has a frame assembly which may be extended and retracted, a mast which may be raised and lowered and a support arm which may be raised and lowered.

Abstract: A high torque low speed motor has a nutating assembly driven by a hydraulic or an electric actuator. The nutator assembly drivingly connects to an output shaft through a gear train. Because of a difference in the number of teeth between a gear on the output shaft and a gear on the nutating assembly, the output shaft is driven at a differential ratio as the nutator assembly is driven.

Abstract: A releasable sinker assembly includes a sinker having an opening and a spindle having a main body adapted to extend through the sinker opening, an enlarged base at one end of the spindle and attaching means for attaching the spindle to a fishing line at the other end of the body. The base is formed of an elastomeric material and is larger in size than the sinker opening. The sinker opening and the base are sized such that the base cannot pass freely through the opening when the base is in its free state but the base may be deformed and pulled through the opening when the sinker is held in place.

Abstract: A noise abating automotive brake shoe assembly consisting essentially of a mixture of from about 2 to about 30 percent by weight of a discrete, heat-cured, particulate, elastomeric, sound damping material containing cashew nut shell resin, nitrile rubber, resin binder, a fiber selected from a group consisting of metal, glass, mineral rock wool and refractory with the remainder being friction material ingredients.

Abstract: A mandibular movement measuring device for measuring the angular movment of the mandibular incisal edge between the mandibular closed position and the maximum mandibular open position and for measuring mandibular deflection and deviation between the mandibular closed position and the maximum mandibular open position.

Abstract: A manual servo control valve for variable displacement axial piston pump incorporating a blocking mechanism which serves to block the inlet and outlet ports of the valve when the valve is not operating to change the displacement of the pump.

Abstract: An electronic system connected to a power transmission line having a fluctuating load for automatically providing increments of voltage to the line to supplement voltage losses from the load by sequentially connecting tapes on the windings of a transformer in response to changes in line current.

Abstract: In rock or roof bolts, in particular combined rigid profile and stretch or strain roof bolts, the bolt bar, except for the bar tip is surrounding by a sheathing tube and the end thereof projecting out of the drillhole mouth is made tensionable with respect to the rock by means of an anchor plate and a screw means. To ensure the immediate loadbearing capability of such a roof or rock bolt, in particular in the filling mortar method, at least one portion (5) of the sheathing tube (3) is provided as expansion element with cutouts (7) distributed into slots (8) and the bolt tip (2) is formed as abutment.

Abstract: For making drill holes, in particular under cramped conditions, an apparatus is used which comprises a drill rod consisting of individual segments and guided in the cradle or slide. The individual segments comprise end pieces which are constructed as centering bushes and guide bushes and are to be pushed into each other in such a manner that the necessary torques and pressure forces can be effectively transmitted from the drilling motor. The drilling motor itself is displaceable between two clamping tongs which fix the drill rod or the individual segments and ensure that the latter form in each case a rigid unit to which the pressure and rotary forces can thus be effectively transmitted. The flushing hose extending in the individual segments is connected via a rotary duct to the guide segment of the drill rod so that said hose itself does not participate in the rotation and can therefore be led with the loosely engaging segments round a curve.

Abstract: An apparatus for magnetically treating a liquid is disclosed herein. The apparatus includes at least two magnetized inserts mounted in a pipe containing a liquid to be treated. The inserts are disposed parallel to one another and parallel to the direction of flow of the liquid to be treated wherein each of the inserts includes a plurality of successive permanent magnets abutting each other and positioned such that the magnetic flux of each magnet is perpendicular to the direction of fluid flow, wherein the polarity of adjacent magnets of an insert alternates in direction, and wherein each magnetic insert is located opposite an identically polarized magnet in an adjacent insert.
