Patent CA-2050375-A1 (CA)
Inventor: BORNHORST JAMES M
IPC: F21V9/40
Filed: 1991-08-30
Abstract: A lighting instrument having pivotable dichroic filters (20) arranged in a substantially radial arrangement with respect to a projected light beam. Multiple sets of such filters are spaced along the axis of the light beam (12) to vary the color of the light beam emitted from the instrument. A gearing mechanism rotates all filters of each set in synchronization with each other and independently with respect to filters of the other sets. The filters may be positioned to pass unfiltered light to vary the saturation of the light beam. <IMAGE>
Patent CA-2058245-A1 (CA)
Inventor: HU DEZHONG
IPC: C25D21/08
Filed: 1991-12-20
Abstract: Abstract This invention relates to a micro-effluent process for rinsing water and equipment for the same in industrial processing, especially in electroplating processing The process of the present invention is char-acterized in that periodically tank-turning over, that is, at definite time intervals, the rinsing solution is transferred from the first rinse tank to a high-level storage tank or to a working-tank (plating-tank), from the second rinse tank to the first rinse tank, and so on and so forth, at last from the last rinse tank to its preceding tank, and the empty last rinse tank is filled up by clean water with a flow rate of less than 400 l/h, or filled up with clean water periodically at a definite time interval same as that for tank-turning over. According to the present invention, the rinsing water overflowed from the last rinse tank can be discharged directly, the cleaning quality of work-pieces accords with requirement, the re-covery of the plating solution is maximized, and the water consump-tion is greatly reduced. This invention is also applied widely in other rinsing processes, such as in printing-dyeing industry and butcher busi-ness and so on.

Title: Method of checking the admissibility of setting up virtual connections
Inventor: WALLMEIER EUGEN
IPC: H04L12/54
Filed: 1992-04-07
Abstract: ABSTRACT OF THE DISCLOSURE       It is presumed in the method that message cell streams having a high cell loss priority as well as message cell streams having a low cell loss priority appear on an ATM transmission line.          The  check  of  the  admissibility  of  the  set-up  of  a  virtual connection via such a transmission line occurs in two steps.  In a first step, a first capacity limit value, or a second capacity limit value that is lower in comparison thereto, is defined for the ATM transmission line based on the measure of the message cell streams having high cell loss priority, including the message cell stream to be potentially taken into consideration to be set-up.          Proceeding on the basis of the respectively defined capacity limit value, a check is then made in a second step to see whether -taking into account all message cell streams transmitted via the corresponding ATM transmission line  -  a  set-up of a virtual connection that has just been requested is possible.

Title: Fluidized bed reaction system for steam/hydrocarbon gas reforming to produce hydrogen
Inventor: ADRIS ALAA-ELDIN M
IPC: B01J8/00
Filed: 1992-10-22
Abstract: Hydrogen gas is generated in a fluidized bed reactor by reacting gases namely steam and a hydrocarbon gas such as methane or natural gas in a fluidized bed of particulate catalytic material. The catalytic material is fluidized by injecting the mixture of the reacting gases at the bottom of the bed.  Hydrogen generated within the bed is removed via a selectively permeable membrane that extends through the bed and through a freeboard area above the bed. The reaction is endothermic and therefore heat to maintain the bed at the desired temperature is added as required. preferably a separator separates particulate catalytic material entrained in the gases in the freeboard area and delivers the particulate material separated from the gas back into the bed.

Patent CA-2084284-A1 (CA)
Title: Divider synchronization circuit
Inventor: COSAND ALBERT E
IPC: H03L7/189
Filed: 1992-12-01
Abstract: A divider synchronization circuit (11) that provides faster settling to a new in a phase-locked loop frequency synthesizer (10) that uses a programmable divider (16) and a phase detector (17). The circuit (11) is adapted to stop the divider (16) while its program is being changed, and then restart the divider (16) on command. The startup time of the divider (16) is automatically adjusted such that the divider output is in phase with a reference input to a phase detector (17). The outputs of the phase detector (17) are also blanked during the time period that the divider (16) is stopped. The circuit (11) reduces the time required for the phase locked-loop frequency synthesizer (10) to settle to its new frequency and phase when frequency is changed. The timing of the divider startup eliminates the large phase transient that may occur when the divider startup timing is random, thus shortening the time that must be allowed for the synthesizer output to settle to its final phase. This circuit (11) is of particular value in a fast settling synthesizer design in which a VCO is pretuned to a close approximation to the new output frequency and then the loop is closed to drive the frequency to its exact value. The circuit (11) is well adapted for use in spread spectrum and frequency-agile radar systems, or spread spectrum communications systems.

Title: Loop formation in on-machine-seamed press fabrics using unique yarns
Inventor: DAVENPORT FRANCIS L
IPC: D06M101/00
Filed: 1993-01-12
Abstract: ABSTRACT OF THE DISCLOSURE          A press fabric for use on papermaking and similar machines is of the open-ended variety, and has loops at each end  enabling  it  to  be  closed  into  endless  form  during installation on the machine by means of a pin seam.   The machine-direction (MD) yarns, from which the loops are formed during the flat or endless weaving of the fabric, are composite yarns having a core yarn with a sleeve-like coating.   The coating, either permanent, semi-permanent, or soluble, gives the composite yarn a monofilament-like structure enabling good loop formation and stability.  The use of multifilament yarn as the core yarn provides a fabric having improved elasticity in the machine direction, and a greater degree of resiliency, following the removal of a soluble coating material, than can be obtained using monofilament yarn.

Filed: 1993-01-20
Abstract: WIRE FEEDER AND METHOD OF ADJUSTING SAME                  Abstract of the Disclosure A pusher system (12) extracts a wire (11) from a reservoir (10) and feeds the wire through a wire guide (13) to a puller system (14). The puller system then feeds the wire (11) through a tip (15) to the welding operation represented by an arc (16) and a work piece (17). The pusher system (12) has a motor (20) adjusted so as to feed the wire (11) at the desired rate. A pair of rollers (22), which are driven by the motor (20), are designed to slip on the wire (11) if the wire becomes jammed or blocked. The puller system (14) has a limited torque motor (30). The limited torque motor (30) drives a pair of rollers (32) which firmly grip the wire (11) and do not slip on the wire (11). If the wire (11) becomes blocked or jammed then the motor (30) will stall. The combination of the pusher system (12) and the puller system (14) provides a wire feeder which does not damage the wire (11) and which does not cause birdnesting if the wire is jammed or blocked. The present invention also describes a method for adjusting a wire feeder to obtain these results.

The support part (20) has a through opening (21) for the pull rod (10) and has a front support surface (23) which rests at least partially on a rear crosswall (3) of the housing (2).    In order to prevent dirt from penetrating from above in such a front jaw (1) and to give the designer greater freedom with respect to the choice of material, the inven-tion provides that following the rear crosswall (3) of the housing (2) there is arranged an insert plate (100) essen-tially resting on the crosswall and extending vertically, on which insert plate the support part (20) rests in certain areas.
