Abstract: Title BALANCED REGENERATIVE CHARGE DETECTION CIRCUIT FOR SEMICONDUCTOR CHARGE TRANSFER DEVICES            Abstract of the Disclosure In order to use a flip-flop amplifier for regenera-tive sensing of the binary output stream of a many-stage main semiconductor charge transfer device section, an auxiliary semiconductor charge transfer device section of hut a few or a single transfer stage is fabricated in close proximity of the output diode of the main semiconductor charge transfer device section.  This auxiliary charge transfer device section is arranged to provide an output stream of unilevel charge packets which are midway between the binary change levels of the output stream in the main semiconductor charge transfer device section.  By means of preamplifiers which sense these output streams from the main and the auxiliary charge transfer device sections, a gated flip-flop detector can be fed by the preamplifier in such a way that the gated flip-flop detector flips into one or the other of its states depending upon whether the instantaneous level in the main charge transfer device section is greater or less than that of the auxiliary charge transfer device section.  Thus, the output of the flip-flop amplifier is representative of the instan-taneous binary level of information output of the main semiconductor charge transfer device, and this output of the flip-flop amplifier can then be fed to a buffer amplifier whose output is useful as input for further circulation in the main charge transfer device section.

Abstract: SURGICAL EVACUATOR           Abstract of the Disclosure A wound drainage container for withdrawing and collecting body fluids from a patient is equip-ped with a valved fluid inlet port and with a fluid outlet port having a one-way valve for emptying the container and for preventing the entry of contaminants into the container.  A gate movable between a first position and a second position is provided for actuating the inlet valve.  When the gate is in the first position it opens the inlet valve and covers the outlet valve which is located adjacent the inlet valve, and when the gate is in the second position it closes the inlet valve and uncovers the outlet valve so that fluid in the container may be emptied therefrom without the danger of the fluid being flushed back into the patient's wound.

Abstract: Abstract of Disclosure A continuous tone dry process imaging film includes a solid, high optical density and substantially opaque film of dis-persion imaging material deposited on a substrate.  Energy is applied to the film of dispersion imaging material, in an amount sufficient to increase the absorbed energy in the material above a certain critical value, to change the same to a substantially fluid state in which the surface tension of the material acts to cause the film, where subject to the applied energy, to disperse and change to a discontinuous film comprising openings and deformed material which are frozen in place following the application of said energy and through which openings light can pass.  Means are associated with the film of dispersion imaging material for retard-ing the change to the discontinuous film, caused by the surface tension, and for controlling the amount of such change in accord-ance with the intensity of the applied energy above said certain critical value to increase the amount of such change and the area of the openings in the film and decrease the area of the deformed material in the film and, therefore, the optical density in accord-ance with the intensity of the applied energy above said certain critical value for providing continuous tone imaging.

Abstract: Abstract of the Disclosure Metal pipe is manufactured by sequential press bending through cold working comprising crimping a metal plate, forming it into U-shape and O-shape, and welding the butt portion extending along the longitudinal direction of the O-formed workpiece.  The improved method comprises finish forming part of length of the U-formed workpiece in the longitudinal direction from the front end partially into the O-shape, effecting transition forming of the workpiece simultaneously so that the portion adjacent to the rear end of the finish formed portion approaches the cross sectional shape from the U-shape to O-shape gradually toward the front end and the gap between opposed edges becomes gradually narrowed.  The workpiece is advanced stepwise by a length less than the length of the finish formed portion, and forming of the work-piece into the O-shape and feeding are repeated alternately, finishing the U-formed workpiece into the O-shape cross section over its entire length. With this improved method, forming can be carried out with forming load of about 1/2 as compared with the conventional method, and also a wall thickness of the pipe to be formed can be improved by more than 50%.

Abstract: ABSTRACT      An image encoding apparatus and technique in which raster scanned data is processed so that the characters represented thereby are thinned into a series of strokes.  These strokes represent the shape of the characters, either their centre lines or their outlines.  The modified bit pattern representing these strokes is then processed in a line follower which detects contiguous bits and determines whether contiguous bits conform to a predetermined constraint.  A series of segments are produced representing the tracked strokes.  Each segment is coded by shape and the position of its end point.  The image is thus encoded as a series of segments in a segment list.
