Abstract: INDUCTION HEATING ASSEMBLY INCLUDING AN  INTERPOSED CLOSED CONDUCTIVE LOOP FOR   SUPPRESSION OF INTERCOIL COUPLING                 Abstract of the Disclosure An induction strip heating assembly is provided having multiple induction coils disposed in coaxial tandem and including at least two coil power sources for generation of first and second inducing currents in the coils for the induction heating of a workpiece, such as steel strip, passing therethrough.  It is a feature of the invention that the assembly includes a closed loop of electrically conductive material coaxially interposed relative to the induction coils and disposed for induction therein of a circulating current opposite to a one of the inducing currents whereby a magnetic field of the circulating current in opposition to an inducing magnetic field of the inducing current causes a reduction in net magnetic field strength on a side of the loop opposite of the inducing current.  Such an assembly provides suppression of intercoil magnetic coupling so that the coils may be spaced adjacent one another with less space between them than would be required if no loops were used.

Title: Liquid strainer
Inventor: VERREAU GILLES R
IPC: B01D29/085
Filed: 1991-04-08
Abstract: The invention is directed to a liquid strainer and a  blank for forming the strainer.   The strainer has  a  conical shape  with an apex portion completely surrounded by a  filtering cloth  and  folded  from  the blank  to  exclude  any  unfiltered passageway.   The blank has the general shape of a disk truncated about  two angularly spaced radial sides,  the angle between  the sides  allowing for formation of a conical shape when  the  sides overlap. A   circular  aperture  is  partly  carved   at   the intersection  of  the two sides, the remaining  portion  of  the aperture is surrounded by a ring extending from the  sides.   The aperture is covered by a filtering cloth peripherally adhering to the blank and the ring.  When the blank is folded, the ring forms and  continuously extends from the latter.   The filtering  cloth which  is  glued  to the ring completely  closes  any  passageway through the folded cloth.

Title: Electro-magnetic desensitizer
Inventor: SCHWARZ WERNER
IPC: G08B13/24
Filed: 1991-05-15
Abstract: Abstract of the Disclosure The  invention  is related to a process  of  deactivating  a magnetic  security marker of an article surveillance  system, wherein   the  security  marker  is  detected  by  simulating conditions  normally  present in  such  a  system,  e.g.,  by creating  between  a  transmitter and a receiver  a  sinewave electromagnetic  field and  the  deactivating  the  security marker by means of the electronically switchable  magnetizing apparatus  in response to the detection of the magnetic field which  corresponds   to  the magnetization  of  the  security marker  in  the surveillance zone.  It is the object  of  the invention  to  enable  the magnetic  security  marker  to  be deactivated  using any alternating power line.  To this  end, the  magnetic  system is automatically connected to  a  power line  without  circuit  change when the  security  marker  is detected.  The  magnetizing  apparatus gradually builds up  a magnetic field by rectifying the flow current,  monitoring it by a current sensor and increasing it at each change of phase until the current reaches a level to which the sensor is set as  effecting  deactivation.   Thereafter,   the  magnetizing apparatus is electronically disconnected from the power line.

Abstract: ABSTRACT OF THE DISCLOSURE A side shifting mechanism for a transaxle includes a shift shaft which is rotatably mounted about an axis which is parallel to the axes of the drive axles.  A portion of the shift shaft extends out the side of the transaxle to a location where it can be conveniently grasped by an operator.  The shift shaft cooperates with a detent plate located within the transaxle.  The detent plate is pivotably mounted on a pivot shaft.  Rotation of the shift shaft causes pivoting movement of the detent plate about the pivot shaft.  The detent plate is connected to an axially movable shifting collar.  The relative position of the collar determines which of a plurality of gear ratios of the transaxle is selected for use.  Thus, by rotating the shift shaft, the operator can select a desired gear ratio.  In a first embodiment of the invention, the shift shaft and the detent plate are formed having cooperating bevel gear portions.  In a second embodiment of the invention, the shift shaft carries a cam driver having a helical groove formed therein which cooperates with a cam formed on the detent plate.
