Patent CA-2209029-A1 (CA)
Inventor: JIANG SHOUGANG
IPC: A63F7/06
Filed: 1997-07-15
Abstract: The traditional table soccer or fussball game (commonly known and written as "foosball" in North America) is intended to imitate the sport of football in a drawer-like structure placed on the ground or floor, with playing figures fixed on horizontal rods to pass and kick a ball into the goal of the rival operator to score points. In this invention, certain mechanisms are designed and employed as a general improvement of the traditional game structure to allow the game to be placed steadily and played on tables with flat surface found on most dining and coffee tables. Four or more suction cups mounted to the bottom of the game table provide a strong suction and adherence to the table surface, leaving the game structure virtually unmovable in relation to the table, thus eliminating the need for heavy and bulky structure and legs used on traditional table soccer game tables to keep the game steady during sometimes vigorous play.Compact goal assembly is designed to minimize the space for receiving the ball and dissipating ball energy through multiple rebound and cushioning. Springs of special design are used as bumpers positioned on the playing rods to prevent game parts from dashing against and damaging the game structure.

Abstract: The present invention provides a device for cleaning, comprising a cleaning head adapted for use in connection with a handle or, in the alternative, in connection with the hand of the user. The cleaning head comprises a first layer of material and a second layer of material joined to the first layer to define a pocket having a pocket opening. The pocket and the pocket opening are sized to receive a hand or, in the alternative, a support plate attached to a handle. The second layer defines a slit extending from the pocket opening to form a first flap and a second flap. Preferred means for closing the slit comprise a tab of material having looped projections attached to one flap and a tab of material having hooked projections attached to the other flap. The tabs are positioned and sized to provide a range of overlap that engages the loops and the hooks, thereby accommodating a range of hand sizes and shapes or, alternatively, support plate sizes and shapes. The preferred material of the cleaning head comprises a non-woven material of about 30% viscose and about 70% polypropylene.

Abstract: A continuous-time tunable Gm-C architecture for a .DELTA..SIGMA. modulator 10 includes a tunable resonator 18 and a low bit, high sample rate quantizer 22 connected in a feedback loop 27.  The resonator shapes the quantization noise spectrum so that the bulk of the quantization noise occurs outside the signal spectrum.  A tunable Gm cell 30 tunes the resonator's resonant frequency to the signal spectrum's carrier frequency to maximize the modulator's SNR.  The tunable Gm cell includes a fixed Gm cell 80 having transconductance Gf, a current divider 82, and a recombination circuit 83 that together effectively multiply Gf by a factor .alpha., where -1 <= .alpha. <= 1, without effecting the cell's common mode current Icm. A positive current source (21a, 21b) supplies Icm, while maintaining a common mode resistance of R/2 and a theoretically infinite differential mode resistance.  Thus, the resonator's resonant frequency can be varied from DC to approximately 1 Ghz while maintaining a stable common mode operating point and improving the modulator's quality factor.

Title: Positioning system for controlling optical alignment of optical waveguides
IPC: G02B6/35
Filed: 1997-09-09
Abstract: A  positioning  system  is  provided  for  controling  the optical alignment of optical waveguides.   At least one optical  waveguide  is  mounted  to  a  first  displaceable terminus and an opposite waveguide is mounted to a second terminus.  A force can be applied to one of the termini so as to cause  an essentially lateral  (radial, pivotal etc.)  misaligning movement  of  the  end portion of  the respective optical waveguide relative to the end portion of the opposite waveguide mounted to a second terminus, the end portions being separated by an air gap. The force required to move the displaceable terminus is provided by a first elastic member having a relatively low stiffness, such  as  a  spring with  a  low  spring  constant.    When exerted,  the force is counteracted by a second elastic member,  such as a spring having a higher stiffness,  or spring constant, than the first elastic member.    In an embodiment of  the  invention,  the displaceable terminus may itself form a resilient member to which the first elastic member is connected for exerting the displacement force.  When a large stiffness ratio between the elastic members  is  selected,  it  is possible to attain a very precise  alignment  control  of  the  opposite  optical waveguides by reducing the movement of relatively simple actuators such as hand-operated levers or lead-nut and lead-screw combinations into considerably finer movements of  the  displaceable  terminus  with  the  concomitant misalignment of the respective optical waveguide.

Title: Clock control system and method
Inventor: STRAHLIN KARL GUNNAR
IPC: G06F1/08
Filed: 1996-03-25
Abstract: First and second parallel processors operate in one of plural modes including synchronous and stand-alone modes. Each processor includes a clock for selectively providing a first high frequency clock signal to both processors.  Each processor also includes electronic circuitry operating at a second frequency lower than the first frequency which generates a clock selection signal that selects one of the clocks from the first and second processors to clock both processors. The electronic circuitry, in response to mode change signals, generates clock switching control signals at the lower frequency. The lower frequency clock control signals are reclocked so that they are synchronous with the first frequency clock signals before being used to select one of the clocks.

Title: Grain processing apparatus and methods
Inventor: SCHMIDT ARNOLD
IPC: B02C13/06
Filed: 1998-02-24
Abstract: A grain processing apparatus is used in one embodiment for debranning grain to remove the bran. In another embodiment, it is used as a mill for milling flour. The processor includes a cylindrical drum with an internal rotor having a set of impeller rods. The grain is loaded into the drum and is withdrawn as debranned kernels or flour as treatment proceeds. Bran removed from the grain is withdrawn through a vacuum discharge at the top of the apparatus. The grain is either discharged through a grain discharge or, where it is to be milled, it is withdrawn through the vacuum discharge as flour. The relatively coarse bran can be separated from the flour using a sifter. The air flow withdrawing the flour from the drum is drawn into the drum at the bottom, through a venturi and a valving arrangement. This cools the inlet air and maintains the temperature of the drum at an acceptable temperature.
