Patent CA-2007023-A1 (CA)
IPC: H02M1/00
Filed: 1990-01-03
Abstract: ABSTRACT          An  inverter circuit  is  provided  in  which  two  semiconductor switching elements are arranged in series between the positive and negative pole of a d.c.  source.    An alternating current can be derived between the two semiconductor switching elements. The two semiconductor switching elements are operated with a pulse width-modulated operating signal,  it being possible for the scanning ratio to vary this signal in time  to produce a current at the inverter outlet that correspondingly varies with time.   Each semiconductor switching element requires a certain switching off period to be changed from a conductive into the non-conductive condition after the arrival of a command.    The switching  off  period  increases  the  risk  of  short  circuits between the two poles of the d.c. source.    For compensation purposes,  ignition  retarders  could  be  employed.     However, these  change  the  predetermined  scanning  ratio  so  that  the outlet  voltage  no  longer  corresponds  to  the  predetermined desired voltage.   According to the invention, an outlet voltage is obtained that fairly accurately corresponds to the desired voltage without the danger of short circuits by merely operating one of  the  two semiconductor  switching  elements  whilst  the other one remains blocked.

Title: Split extrusion die assembly for thermoplastic materials and methods of using the same
Inventor: BURRAFATO JOHN F
IPC: B29C48/12
Filed: 1990-01-03
Abstract: ABSTRACT A die spool for the extrusion of thermoplastic materials includes an axially split elongate spool body so as to be separable into first and second spool segments. The spool segments collectively establish the spool body and also define an axially oriented extrusion cavity through which thermoplastic material is conveyed. An alignment system ensures that only a single orientation of the extrusion axis is possible when the die spool is coupled to another similar die spool (or to an extrusion die associated with an extruder). A die spool assembly may therefore be provided which is comprised of a number of individual die spools. Preferably, a decreasing temperature gradient is established within the extrusion cavity of the die spool assembly (as may be accomplished by controllably operating electrical resistive heater elements) so as to at least partially solidify the thermoplastic extrudate therewithin. During extrusion start-up, a lower die spool segment is employed to support an initial length of thermoplastic extrudate, with the upper die pool segment being mated therewith (thereby collectively defining the extrusion cavity) once the extrudate extends beyond the downstream end of the lower segment. In such a manner, manual conveyance assistance along the extrusion axis may be imparted to the extrudate during start-up.

Abstract: ABSTRACT OF THE DISCLOSURE       A module for the storage of nuclear waste packages from a nuclear power plant is disclosed comprising a concrete precast container with sidewalls and a bottom, a concrete precast lid removably disposed on upper edges of the sidewalls to close the container, and a cylindrical one-piece seamless liner abutting and covering the interior surface of the container.  The liner is provided with anchor means formed integral with the liner that extend along outside surfaces of the liner sidewalls and bottom wall, and the anchor means is embedded within the concrete precast sidewalls on the container.  The anchor means is provided by a plurality of ribs which can be T-shaped or dovetail shaped in cross-sectional area and may extend either longitudinally or circumferentially about the liner. The module is manufactured by the first forming a one-piece seamless liner including the ribs on its outer surfaces, placing the liner in a mold for the module, and thereafter pouring concrete into the module mold to completely fill the space between the liner and the mold for embedding the ribs within the concrete.  The integrally formed liner provides and additional barrier for nuclear wastes that is advantageously devoid of seams or weld joints.  The manufacturing method of the invention insures a perfect, gapless fit between the liner and the concrete module.

Abstract: CANADA           Rogers, Bereskin & Parr INVENTOR: Roy Edward Smith TITLE:  FLEXIBLE DRIVE COUPLING     ABSTRACT OF THE DISCLOSURE            A  flexible drive   coupling   for   transmitting rotational forces between respective flanges of a driving shaft and a driven shaft.  The flexible drive coupling has, in a substantially planar circular configuration,  a number of wedges.  The wedges have respective end faces facing the adjacent wedges and connected thereto by flexible elements.          Alternate wedges attach respectively to the flanges of the driving and driven shafts. The flexible elements consist of a link between two end plates.  The mating faces of the link and the end plates are curved so that they co-operate one with the other.   An elastomeric filler occupies the space between the curved surfaces of the end plates and the links permitting each end plate to pivot with respect to the link by deforming the elastomeric filler. The end faces of the wedges  and, the corresponding faces of the end plates of the flexible elements which face them, have co-operating tabs and recesses to prevent relative radial and axial movement.          On attaching the flexible drive coupling to the driving and driven shafts, the wedges can be forced radially inward and so secured that  the  flexible  elements  are pre-loaded  in radial compression.

Title: Fast optical switch and limiter using quantum size effect in metal grain composites
Inventor: HAUS JOSEPH W
IPC: G02F1/35
Filed: 1990-06-26
Abstract: A block of composite material includes a dielectric material with a dielectric constant of ~ d = 4.66 and which is at least 4 µm thick and has electrically conductive microparticles randomly distributed throughout.  The composite material exhibits an optical bistability without cavity feedback.  The microparticles must be nearly uniform in size and of spherical diameter much smaller than the wavelength of light in the particle.  The composite, when illuminated by laser light in the range of 500 nm and of varying intensity, becomes opaque at a critical input intensity and stays opaque until the input intensity reaches a certain level both below and above the intensity at which it initially became opaque.  Thus the material behaves as an optical switch and a limiter.

Title: Method and apparatus for removing leaves from a pool
Inventor: GOETTL JOHN M
IPC: E04H4/16
Filed: 1990-10-29
Abstract: A method and apparatus for removing leaves from a pool by inducing turbulence in the pool water to stir up leaves within local regions of the pool, and directing a steady jet of water from a stationary jet to provide a fix-ed direction gathering stream or pathway to capture and carry leaves to the inlet of a leaf receiver which is fixed in position at the end of the pathway. Local area turbu-lence can be achieved in various ways, including the use of manual sweep brooms, water jet propelled devices carrying flexible sweep hoses, or an arrangement of rotary nozzles operative to sweep across and induce turbulence over compar-atively large local regions of the pool. The leaf receiver is connected by a conduit to an externally located forami-nous leaf collector mounted in a collector tank from which water is pumped, leaving the collected leaves in the leaf collector. An access cover in the pool deck can be opened to reach and withdraw the leaf collector for emptying. The leaf collector is an the inlet side of the pool pump, doub-ling as a pump leaf basket, and the usual. pool filter is on the discharge side of the pump. The pump discharge is through a conduit having venturi orifices to draw water from the collector tank for discharge through a conduit emptying into the pool.
