Patent CA-1157092-A (CA)
Inventor: HENDRICKSON THOMAS E
IPC: H02M3/145
Filed: 1979-12-04
Granted: 1983-11-15
Abstract: ABSTRACT         The invention provides a circuit with a field-effect transistor device, or devices, to be used in controlling power transfers between an alternating polarity power supply and a load, where this supply and load, in operation, would be connected on either side of the device channel or on either side of device channels connected in series.  In one form, there effectively are unidirectional current conducting means electrically con-nected from either side of the field-effect transistor device-channel to the gate region of that device, selectively through either an energy storage means or directly, the selection being made by selectively operated swit-ching means.  The energy storage means can be such as to obtain its energy from the alternating polarity power supply through use of at least one other undirectional current conducting means.  In another form, the field-effect device, with either side of its channel connected in this manner to the alternating polarity supply and load, has its gate operated by a second field-effect transistor device.  This second device is connected to a bias control means to thereby selectively control the power transfers from the alternating supply to the load.  This second field-effect device has its gate controlled by the alternating polarity power supply during operation.

Abstract: ABSTRACT  OF THE DISCLOSURE     A turbine that is rotatably responsive to the pressure of an applied moving fluid comprises a simple unitary structure that includes a pair of end disks which are spaced apart in coaxial relation, and a plurality of curviplanar vanes having rectilinear sides that join the facing sides of the disks.  The vanes are formed as right circular planes that are radially and symetrically posi-tioned about the axis of rotation.  Innermost end portions of the vanes overlap and define a longitudinally slotted polygonal hollow cylinder aligned coaxially with the axis of rotation.  Fluid advancing into a chamber formed by the combination of the end disks and adjacent vanes is com-pressed and applies a force to induce rotation.  The com-pressed fluid then enters the cylinder through one slot and is distributed through the other slots to eliminate a negative pressure condition on the trailing sides of the other vanes advancing against the fluid, thereby improving efficiency.

Abstract: T&B 834F            ABSTRACT OF THE DISCLOSURE:          In connecting flat multiconductor cables, one cable is placed atop another to provide a matrix of zones in which connections may be made of any conductor of one cable to any conductor of the other cable. Selection is made of one zone and it is perforated. An insulation-piercing connector is inserted through the perforation and crimped to provide an electrical connection between the pair of cable conductors in registry with the selected zone.  Selection of further zones for perforation and connector insertion is made progressively from those zones which do not have in registry therewith any conductor which was in registry with any previously selected zone.  Apparatus for implementing preferred connection zone selection precludes use of connecting zones other than a singular zone for connection of one conductor pair and compels use of a selective few zones individually for connection of respective other conductor pairs, thereby lessening connection error likelihood.

Title: Method and device for removing a ring traveller  from the ring of a ring-spinning or  ring-twisting frame
Inventor: HOLENSTEIN ERNST
IPC: D01H17/00
Filed: 1980-08-29
Granted: 1982-08-17
Abstract: ABSTRACT    The tool is supported by a support face on the upper side of a spinning or twisting ring, with a bearing face bearing on the outer edge of the ring.  A hook engages by a tip below the inner end of a ring traveller, which is brought into a predetermined position by a permanent magnet let into the support part.  By actuating the tool, the hook is moved in the direction of the support face, so that it lifts the ring traveller over the inner edge of the ring.  After passing over the inner edge and due to its spring action, the expanded ring traveller jumps into a channel, which leads to a collecting container.          With such a removal of the ring traveller from the ring, the yarn drawn by the ring traveller remains undamaged.

Abstract: ABSTRACT OF THE DISCLOSURE A tool or building construction implement is disclosed for use in constructing brick work, particularly for use by a bricklayer in construction of brick walls, or other brickwork, of conventional bricks and mortar.  With use of the present invention, need is eliminated for the usual mortar board and trowel.  The mortar trough is semi-cylindrical in shape, containing when filled with mortar the exact amount of mortar required to prepare brick joints cleanly and with savings of mortar otherwise wasted when excessive amounts are applied.  The mortar trough requires no handle, and can be used for work in crowded places, such as under an overhang, near walls, and the like.  In a first method of use, rotation substantially about a longitudinal axis allows deposition of the mortar contents on the row of bricks to be built up with an additional layer.  In a second method of use, the trough can be filled and tilted to permit the mortar contents to flow along the surface to be worked.          The trough is closed at one end and left open at the opposite end.

Granted: 1983-10-04
Abstract: ABSTRACT OF THE DISCLOSURE     A bearing has a self-lubricating liner including sheets of felted polytetrafluoroethylene fibers impregnated with cured phenolic resin having no surface bonding to the fibers.  Sheets of fibrous fabric are felted to sheets of felted fibers.  Sin-tered particles are dispersed in the low friction surface of the liner.  Liners are formed by air drying resin-impregnated sheets of felted fibrous material.  The resin may be cured in a heated platen press before assembly of the bearing.  The bearing is assemhled by deforming bearing members to form an interference fit between the members and a bearing liner disposed therebetween.           Parting compound applied to one of the bearing members prevents bonding of the liner to that member when the liner is baked to cure the resin and bond the liner to the other member.         Bushes and bushings having self-lubricating linings are disclosed.  Arbors and mandrels form an interference fit between the linings and bushes and bushings during assembly.

Abstract: ABSTRACT     An interference compensation system comprises a first input for receiving an interference signal IA and a second input for receiving a desired signal and an interference signal IM.  An amplitude-phase control circuit adjusts the amplitude and phase of interference signal IA so that the amplitude and the phase of the output signal IVM of the amplitude phase control circuit are the same amplitude and the opposite phase as compared with the interference signal IM.  The output signal IVM of the amplitude-phase control circuit  and the signal IM are combined to provide a compensated output signal IE substantially free from the interference signal.  The control signal is subject only to the amplitude change or the power change of the input high frequency signal, and that control signal is obtained after envelope detection is performed.  Therefore, the interference compensa-tion is accomplished satisfactorily irrespective of the modula-tion method of both the desired signal and the undesired interference signal.  Thus, PSK signals, and FM signals are much better compensated for than in most prior art arrangements.          Further, because of the presence of the amplitude-phase control circuit which controls both the amplitude and the phase of the interference signal, and determines not only the direction of the variable to be controlled but also the amount of the variable to be controlled at the same time, a compensation control having excellent response characteristics is achieved.
