Abstract: ABSTRACT OF THE DISCLOSURE         A composite sheet winding for an electromagnetic induction apparatus (such as a transformer) comprises two or more sheet winding portions, spaced apart axially, and wound on a common insulated core.  The turns of each winding portion, as well as the winding portions themselves, are insulated from one another by common insulation which extends uninterrupted for the complete axial length of the composite winding.       Electrically insulated conductors located at the radial peripheries of the composite winding connect the start and the finish of each winding portion to the end of the composite winding.  Preferably all the insulated conductors exit the composite winding at one common end, and preferably tile winding portions are connected in series to form the composite winding.

The regulator comprises a pair of spaced transverse support brackets securable to said framework and supportably mounting an upwardly opening C frame in said opening for longitudinal and transverse adjustments within said opening. A pair of spaced elevator channels receive and supportably mount the lower edge of an upright window secured thereto. A pair of parallel spaced formed guide rods at their lower ends are anchored to said brackets and at their upper ends are secured to said outer wall. First lateral apertured flanges on said channels receive and are guidably mounted on said rods for a predetermined vertical and translation movement within the window opening. Second lateral flanges upon the opposite side of said channels provide a means of connecting the ends of a pair of elevator cables which are respectively secured to said lateral flanges, and are wound in opposite directions around a rotatable capstan mounted on the inner wall. A series of coplaner longitudinally spaced upper and lower pulleys are supported upon said C frame over which the respective cables extend in such fashion that selective rotation of said capstan respectively raises and lowers said window in a path defined by said guide rods.

Abstract: BRAKE PEDAL POSITIONING MECHANISM     ABSTRACT OF THE DISCLOSURE          A vehicle parking brake pedal positioning mechanism of the disclosure positions a parking brake pedal in an actuated con-dition against pivotal movement toward a released position by an infinite position locking action.  A frame of the mechanism ro-tatably supports the brake pedal and a locking member about a com-mon pivotal axis so as to be rotatable with respect to the frame and each other.  The frame and the locking member respectively in-clude first and second cam surfaces extending about the pivotal axis and having portions with increasing radii from the axis in a direction corresponding to the brake pedal movement from the released position to the actuated condition.  A slide mounted to rotate with the brake pedal but to slide relative thereto has first and second opposite ends respectively engaged in a slidable manner with the first and second cam surface portions on the frame and the locking member such that the slide is locked between the cam surface portions to hold the pedal in the actuated condition in an infinite position manner.  The locking member is normally spring biased about the pivotal axis in a direction so as to maintain the engaged condition between the second cam surface por-tion thereof and the second end of the slide and is selectively moved in the opposite direction to release the pedal for movement back to the released position.  Preferably, the frame of the mechanism has a plate-like construction that is stamped to form a depression having a round aperture concentric with the pivotal axis and first and second round depression portions, with the first round depression portion defining the first cam surface, and with the second round depression portion mounting the locking mem-ber which has a round configuration and a round aperture that de-fines the second cam surface.  A journal fixed to the brake pedal is rotatably supported within the round depression aperture of the frame and within a round aperture in a plate that maintains the locking member within the depression, and the journal includes a slot that receives the slide so that its opposite ends can en-gage the cam surface portions.  A first leaf spring extends between the brake pedal and the locking member to provide the locking mem-ber bias and a pad pivotally mounted on the brake pedal is con-nected to the first leaf spring by a second leaf spring so as to be actuatable to release the locking member.

Abstract: A fluidised bed apparatus suitable for the combustion of fuel has a baffle assembly arranged in the freeboard above the fluidised bed level. The assembly is in the form of a perforate duct which defines within it a passage connecting with the gas exit of the apparatus.  Gases issuing from the bed, in use, and carrying bed material impinge upon the duct and are arranged to follow a vortical path around the duct, resulting in a deceleration of the particles which fall back into the bed.  The gasses pass into the duct for exhaust substantially free from contamination by bed material.  The baffle assembly is of particular value when a gas flows horizontally to a gas exit and prevents or substantially reduces elutriation.

Abstract: TITLE OF THE INVENTION:            REMOTE MANIPULATOR      ABSTRACT OF THE DISCLOSURE:            A remote manipulator of the force reflecting servomaster-slave type comprises manipulator elements capable of at least seven distinct motions corresponding to respective degrees of freedom.  The manipulator elements include an upper arm journalled in a shoulder assembly and a lower arm operatively connected to the upper arm by an elbow as-sembly.  A gripping device such as a conventional tong is secured to the lower end of the lower arm through a wrist mechanism.  Two cooperating motors establish an input output transmission through a differential gear system which permits two motions about axes extending perpendicularly to each other.  One axis defines the longitudinal axis of the shoulder assembly.  The other axis defines the longitudinal axis of the upper manipulator arm.  The parallel drive shafts of the two motors transmit the drive power through parallel gear trains to the differential gear system, whereby coaxial shafts are avoided for the two motions.  A third motor may be provided for a third motion, whereby the power transmission may ex-tend through a hollow shaft, thus providing three motions, although using only one hollow shaft.

A flowable rubber gasket is provided for insertion between two separable portions of the enclosure.  The gasket not only provides watertight sealing for the enclosure when com-pletely assembled but has a bead on the inside surface thereof which shields the corners of the two portions of the enclosure to reduce the corona effects thereat.

The web material is then folded back onto itself and the remaining amount of web material to be placed on the supply spoolis wound onto the spool in a second and opposite direction.  As the web materialis removed from the supply spool, the supply spool hub and/or the shaft for the supply spool will reverse direction of rotation upon reaching the portion of theweb material, which has been folded back onto itself. Also, the angle and point of departure of the web material from the supply spool hub will change. The change in rotational direction and/or the change in the angle or point of departure of the web material from the spool are sensed to indicate the web material on the spool has been depleted to the end portion.

Abstract: ELECTRONIC HALFTONE SCREENING WITH         HALFTONE CELLS APPROXIMATING A PARALLELOGRAM     ABSTRACT OF THE DISCLOSURE         An electronic signal representing the density of pixels in a scanned line in an original image and containing pixels in whole number multiples of a single line of halftone screen partial dot values plus a predetermined extension parameter is electronically halftoned by comparing the pictorial signal with the single line of halftone screen partial dot values to form an electronic halftone image.   An electronic screen function represented by the single line of halftone screen values, produces automatically a rotated halftone screen at a predetermined angle to the original electronic image when the number of pixels in the input, scanned line of the original document is set equal to a whole number multiple of the number of partial-dot values plus a predetermined extension parameter.  Under these conditions, the scanned input is automatically half-tone screened electronically into halftone cells approxi-mating a parallelogram and having said predetermined angle.          The single line of partial-dot values need only be cir-cularly buffered through a comparator.  No electronic indexing or shifting of partial-dot values is required.
