Abstract: A B S T R A C T      A release mechanism for a normally applied, spring-loaded brake includes a valve from a residual source to the brake to release it.  The valve includes pump means whereby further operation of the control cable will pressurize residual fluid in the valve to release the brake if system fluid pressure is lost.  The valve is below sump oil level so that it is always flooded with oil.  This supplies fluid to the valve pump means during loss of system pressure and also allows for bleeding the brake release mechanism by siphoning action whenever the valve is operated.

Abstract: APPARATUS AND METHOD FOR MANUFACTURING A CLOSED TORUS TIRE         Abstract of the Disclosure Method and apparatus for building a cord or wire wound oarcass for a closed torus tire.  An endless flattened inflatable tube providing a liner for the carcass and co-axially spaced bead rings are placed on a support comprising a cylindrical array of rolls.  The bead rings are spaced axially to control the length of each turn of cord or wire wound in the flattened oval path around them.  A single wire or cord is wound in a flat oval orbit about the liner and bead rings by orbiting a spool along a track having two straight parallel portions, one inside, the other outside the bead rings and liner.  The parallel track portions are connected at their ends by semi-circular track portions.           No rigid core is required.  After winding the cord or wire about the liner and bead rings, the liner is inflated and the bead rings are shifted axially toward each other to the axial spacing appropriate for the inflated tire in use.      The foregoing abstract is not to be taken as limiting the invention of this application, and in order to understand the full nature and extent of the technical disclosure of this application, reference must be made to the accompanying drawing and the following detailed description.

Abstract: ABSTRACT OF THE DISCLOSURE A low cost, lightweight, helically preformed line tie is disclosed which is configured for yieldably securing an elongated conductor or the like to various standard sizes of conventional, grooved insulative supports without the need for specialized ties by provision of a unitary, substantially shape-retaining resilient metallic wire tie which includes a central, generally U-shaped, line-receiving bight and a pair of legs extending therefrom which have intermediate sections adjacent the bight and helically formed line-gripping terminal sections; in preferred forms, the intermediate sections include a pair of interconnected, generally straight segments disposed at an angle relative to each other, and the intermediate sec-tions are wrapped under tension about the support body with the helical leg sections secured about the line for yieldably securing the latter to the support without creation of localized, rigidly held stress areas at the line support points which can lead to premature line failure by virtue of bending movements of the line at the support points.  In this manner characteris-tic wind-induced line vibrations can be safely and effectively dampened along a relatively long length of the line adjacent the insulator which reduces wear and tear of the line.  A sim-plified tie forming method is also provided which permits es-sentially automatic, assembly line production of the ties through the use of sequential bend-forming stations and a unique mandrel-type helical forming station which completely eliminates com-plicated forming implements and methods heretofore employed.

Abstract: A B S T R A C T -  CANADA An apparatus for applying multi contact electrical connectors onto cables having a plurality of spaced parallel conductors includes a device for clamping positively the flat cable on a surface so that individual conductors are correctly aligned and located with respect to recesses communicating with the surface.  A pressure block is mounted on a ram for reciprocal movement towards and away from the surface and means are provided for locating a connector between the cable and the pressure block.  When the ram is actuated movement of the pressure block towards the surface causes the pressure block to engage a connector when positioned operatively between the pressure block and the cable.  The contact arms of the contact embrace between them an individual conductor and enter into the associated recess.  Ejector means are provided for ejecting the contact arms from their respective recesses subsequent to the assembly of the contacts to their conductors.

Abstract: ABSTRACT OF THE DISCLOSURE      At a constant charging current the charge capacity of gas-tight storage batteries is strongly dependent upon the temperature: in cold tempera-tures the restrained charge reaction causes the switch-off voltage to be reached after a short period of time, at temperatures above 30°C, however, parasitic secondary reactions occur which absorb the charge current either fully or in part, thereby possibly preventing a full charging and attaining of a switch-off voltage.  According to the present invention, gas-tight storage batteries can be charged up to switch-off voltage by a current which rises in the temperature range of from -10°C to +45°C at increasing temperatures in the form of a straight line.  In this fashion, a good approximation of a full charge is achieved.

Abstract: ABSTRACT OF THE DISCLOSURE         A self-drilling dowel has a drill head extending across its leading end.  A bore extending through the dowel from its trailing end is closed at its leading end by the drill head forming a centrally located blind bore.  The blind bore is cylindrically shaped for a part of its axial length from the trailing end of the dowel with the remainder of its axial length to its closed end tapering inwardly from the surface of the cylindrically shaped part.  A spreader is positionable in the central bore with complementary dimensioned surfaces relative to the cylindrically shaped and tapering parts of the bore.  Slots are formed in the dowel and extend from the drill head to approximately the transition plane between the cylindrically shaped and tapering parts of the blind bore.  The slots have a dimension extending transversely of the axis of the bore just sufficient to open into the bore at the transition plane.  The drill head has a centering point projecting outwardly from the remainder of its surface at the leading end of the dowel.  The part of the drill head forming the centering point is shaped so that it can separate from the dowel when the spreader is driven through the central bore toward the leading end of the dowel.

Abstract: ABSTRACT OF THE DISCLOSURE             The jet of an industrial washing machine jet assembly comprises a passage through a ball which is clamped to one end of a feeder pipe by a nut.  The other end of the feeder pipe is clamped releasably to a header pipe by a stirrup clamp.  Once the jet assembly has been located initially relative to the header pipe and clamped to the header pipe by the stirrup clamp, the plate of the stirrup clamp, the plate of the stirrup clamp is welded to the header pipe so that the jet assembly can be demounted for cleaning and remounted in the same location.  Once the jet assembly is mounted on the header pipe, the jet is orientated by swivelling the ball whilst the nut is slackened off.  The nut is tightened up to clamp the ball in the selected orientation.
