Patent CA-2046269-A1 (CA)
Inventor: SCHNEIDER GEORG
IPC: G01B7/16
Filed: 1990-11-30
Abstract: The arrangement serves to process sensor signals furnished by a sensor which when fed with a supply signal in response to the action of a physical measured quantity generates a measuring effect representing the dependence of an electrical characteristic quantity on the physical measured quantity. It includes a signal processing circuit which operates by the principle of quantized charge transport by means of switch-capacitor structures, The signal processing circuit establishes a charge balance by opposite integration of measuring charge packets dependent on the measuring effect and compensation charge packets independent of the measuring effect and furnishes an analog output signal corresponding to the integration result. The supply of the sensor is influenced by feedback of the analog output signal or of a feedback signal in fixed relationship thereto for obtaining the charge balance. By this feedback the analog output signal is regulated so that it is proportional to the measurement result.

Title: Miab welding machine
Inventor: MACLEOD JOHN
IPC: B23K9/095
Filed: 1991-07-23
Abstract: MIAB WELDING MACHINE                 ABSTRACT OF THE DISCLOSURE      An apparatus for magnetically impelled arc butt welding (MIAB), particularly for welding pipes, is described.  The welding head of the apparatus is disposed outside the pipe being welded.  The apparatus has a pair of clamps which are operable so as to receive the pipes from above (i.e., the clamps open in an upward direction, so the pipes may be lowered into the apparatus).    A MIAB welding method for welding pipes is also described.  The method requires that the pipe movement be monitored during the forging step of the welding. By monitoring the pipe movement, the amount of pipe which is lost as "upset" during the welding operation may be calculated.

Title: Insulation clip
Inventor: PUKAS PAUL
IPC: E04F13/08
Filed: 1991-10-24
Abstract: A clip is disclosed for retaining an insulation panel or the like to a planar surface.  The insulation panel has opposite edges provided with a tongue and groove formation for matingly interlocking with adjacent like panels.  The clip  comprises  a piece of sheet material  having a base adapted to lie flush on the planar surface upon which the insulation panel is to be mounted.  The base is adapted to be  secured  to  the  planar  surface.    The  clip  has  an interlock portion adapted to  follow the contours of the joint between adjacent tongue and groove interlocks.

Title: Commercial vehicle wheel monitoring device
Inventor: HOWARD RAYMOND F
IPC: G01L5/28
Filed: 1992-03-27
Abstract: COMMERCIAL VEHICLE WHEEL MONITORING DEVICE                 Abstract The method and apparatus provides an improved system for moni-toring air brakes of a commercial vehicle.   The system monitors brake temperature, brake lining wear limits and brake adjustment. It can be installed on all commercial vehicles and can operate on trailers as a system within itself.   This becomes very important when  trailers are shuffled from one towing vehicle (tractor) to another.  This system can be tested for operation before the vehicle is put  in motion.   It will indicate any of the above problems, namely, lining wear limits, brake adjustment and heat build up and will indicate with a buzzer and a light at a receiver exactly which wheel is faulty in the system.       A means of counting the faulty brake applications each time the brake pedal  is depressed can be added to this system.   This counter will monitor a preset number of brake applications and will send a signal to any engine having electronic controls.  This signal will put the engine control module into an emergency shut down mode if the problem at the wheel is not rectified.

Patent CA-2070630-A1 (CA)
Inventor: SMITH JAMES W
IPC: B03D1/16
Filed: 1990-12-04
Abstract: Components,  usually  but  not  exclusively gaseous components,  are removed  in a liquid medium from gas streams and chemically converted into an insoluble phase or physically removed.   Specifically, hydrogen sulfide may be removed from gas streams by oxidation in aqueous chelated  transition  metal  solution  in  a  modified agitated  flotation  cell.    A  gas-liquid  contact apparatus,  generally a combined chemical reactor and solid  product  separation  device,  comprising  such modified agitated flotation cell also is described.  In order  to  effect  efficient  mass  transfer  and  rapid reaction, gas bubbles containing hydrogen sulfide and oxygen are formed by rotating an impeller at a blade tip velocity of at least about 350 in/sec. to achieve the required  shear. To  assist  in  the  reaction,  a surrounding  shroud  has  a  plurality  of  openings, generally of aspect ratio of approximately 1, of equal diameter and arranged in uniform pattern,  such as to provide a gas flow therethrough less than about 0.02 lb/min/opening  in the  shroud.    In general,  the gas velocity index is at least about 18  per  second per opening, preferably at least about 24 per second per opening.  Each of the openings has an area corresponding to an equivalent diameter less than about one inch.

Abstract: A channel block ice making system includes a plurality of elongated channels (26), at least partially open at the top thereof, and an associated refrigeration system for supplying coolant to the walls (86), of the channels to form long, heavy channel blocks of ice. Wa-ter is recirculated from one end of said channels to the other end thereof, and after the channel blocks of ice are solidly frozen, the excess water including salts and the like is drained off, the outer surfaces of the channel blocks of ice are warmed, and they are advanced so that the ends of the blocks of ice (118) protrude from the ends of the channels (26), where standard size blocks of ice (126) are cut off. Fins (114) on the sides of the chan-nels (26) score the blocks of ice so that the standard size blocks (126) may be later automatically broken into smaller blocks (166) and packaged. A door or gate (36) is provided for retaining water within the channels (26) during the freezing process, and for permitting subse-quent easy removal of the ice.

Abstract: Using a series of  identically  sized,  single row,  single circuit refrigerant coil modules, fin/tube refrigerant coils of different nominal air conditioning tonnages are constructed by arranging different numbers of the identically sized modules in accordion-pleated orientations, with each modular coil having the same depth in the direction of intended air flow across the coil.        Compared to conventional "A" coils used on the indoor side of air conditioning circuits, these accordion-pleated modular coils are more compact in the air flow direction, provide more coil surface area, permit lower coil face velocities with higher fin density, and significantly reduce the overall coil manufacturing costs since only one size of coil slab needs to fabricated and inventoried to later assemble refrigerant coils of widely varying nominal air conditioning tonnages.   A specially designed one piece molded condensate drain pan structure may be releasably snap-fitted onto the underside of the modular refrigerant coil, and is provided on opposite sides with support structures that are configured to slidably receive an opposed pair of interior rail members within the housing of an indoor air conditioning unit as the connected drain pan structure and modular coil are operatively inserted into the housing through an access opening therein.  Accordingly, the drain pan may be secured to the modular coil, and the coil/drain pan assembly mounted within the air conditioning unit housing, without the conventional necessity of using sheet metal screws to effect these connections.
