Title: Buckle chute folder with clamp
Inventor: OTT ROBERT S
IPC: B65H45/14
Filed: 1987-06-29
Granted: 1992-04-14
Abstract: Abstract of the Disclosure A folder suitable for automatically folding successive sheets of paper, such as engineering drawings, by conveying them into a folder pocket to various distances depending upon where the fold is to be formed.  To arrest the sheet at the proper position in the pocket, a photosensor senses when the leading edge of the sheet has reached a reference position in the pocket and, when the sheet has advanced further to the desired position, a solenoid-operated clamp is actuated to move transversely into the pocket and clamp the sheet momentarily in the desired position while the fold is being made.  The amount by which the sheet advances beyond the reference position is controlled by producing an electrical pulse each time the sheet conveyor moves a predetermined amount, and counting these pulses to cause the clamp to be actuated when a count corresponding to the desired fold position has been accumulated.

Title: Method and apparatus for detecting a sheet strip material misfeed condition
Inventor: MALLOY JOSEPH P
IPC: B21D43/00
Filed: 1988-08-10
Granted: 1992-10-06
Abstract: ABSTRACT A plurality of  individual frames or stampings provided in a sheet strip material by a stamping device are passed in proximity to a sensing device.  As each individual frame or stamping is passed in prox-imity to the sensing device, the sensing device provides a voltage signal to a controller. The voltage signal is proportional to the amount of, or mass of, metallic material in each frame or stamping and the distance between the frame or stamping and the sensing device.   The controller generates an individual waveform from the voltage signal for each frame passed in proximity to the sensing device.   Each individual waveform is a function of the position of the movable portion of the stamping device for one cycle.  As the plurality of individual frames are passed in proximity to the sensing device, a plurality of individual waveforms are generated within the controller.  The waveforms are compared within the controller to detect a deviation between waveforms.  A deviation between waveforms indicates a sheet strip material misfeed condition within the stamping device.  If a sheet strip material misfeed condition is detected, the controller provides a signal to the stamping device to initiate stoppage of the stamping device.   If desired, the plurality of indiv-idual waveforms may also be compared within the controller to detect a deviation in the configuration of the frames or stampings produced by the stamping device from a desired frame or stamping configuration.

Title: Trocar assembly with improved latch
Inventor: HOLMES WILLIAM A
IPC: A61B17/34
Filed: 1988-10-26
Granted: 1994-01-25
Abstract: ABSTRACT OF THE DISCLOSURE    A trocar assembly comprising an elongate trocar obturator having a piercing tip at its front end, an elongate trocar tube in which the obturator is housed, and a tubular protective shield mounted concentrically around the obturator between a normally extended position in which the obturator tip is covered and a retracted posi-tion in which the obturator tip is exposed.  Further included is a spring acting on the protective shield, whereby the shield is forced to the retracted position to expose the piercing tip when the trocar is being inserted through the wall of a body cavity and is biased by the spring to the extended position to shield the piercing tip once the trocar has pierced the wall.  A protrusion extends radially from the shield.   A leaf spring element has one end anchored relative to the obturator and a second end biased to contact the protrusion in a manner preventing movement of the shield from the extended posi-tion toward the retracted position when the element is in contact with the protrusion.  A trigger, coupled to the leaf spring member is shiftable between a lock position and a release position.  When the trigger is in the lock position, the shield can not be moved from the extended position.  When it is in the release position, the shield can travel to the retracted position.  When it moves to the retracted position, it disengages the trigger so that when the shield returns to the extended position, it locks in place, even though the trigger is in the release posi-tion.

Abstract: ABSTRACT    A continuous fluidized process for upgrading a heavy liquid hydrocarbon charge-stock containing solid or solid-forming contaminants, e.g., inorganic solids, metals and asphaltenes.  The charge is atomized to provide a stream of liquid particles introduced horizontally into a horizontal contacting zone to contact a vertical curtain of fluidized hot solid particles so as to vaporize hydrocarbons in the charge without substantial cracking, the solid particles being solely derived from the contaminants in the charge.  The mixture of hydrocarbon vapors and solid particles are rapidly separated, carbon is burned from the separated particles, and the resulting hot solid particles are recycled to the contacting zone.  The hydrocarbon vapors are condensed and there is recovered a liquid product having a substantially reduced content of contaminants.

Abstract: ABSTRACT OF THE DISCLOSURE           A color printer is provided in which a paper sheet is wrapped about a rotatable platen and three colors are printed on the sheet, to obtain an image, by a thermal head and a color ribbon during three rotations of the platen.  In a paper feeding device for the printer, a sheet of paper is fed by a feeding roller, from the bottom of a stack of paper sheets in a paper tray through, a feeding guide to the platen.  The tray has an opening in its bottom plate so as to expose the lowermost paper sheet stored therein.  The feeding roller is provided under the tray and lifts up toward the opening of the tray so as to come in engagement with the lowermost paper sheet, the feeding roller rotating to feed it to the platen.  The width of the platen is less than that of the sheet and the circumference thereof is less than the length of the sheet. Therefore, when the sheet is wrapped about the platen, it extends laterally outward from the ends thereof, and its ends overlap.  Accordingly, during printing, the sheet is securely wrapped about the platen and its position does not shift and the extension of the sheet from the edges of the platen allows a sensor to determine a print starting position by sensing a mark of the edge of the sheet.  Thus, a fixed print starting position is obtained during all three rotations of the platen during the print cycle.

Granted: 1994-05-10
Abstract: Abstract In a plural phase overload relay, a pivot lever (12) is mounted to the ambient compensator deflector (9), and a second pivot lever (34) is mounted to both driver and follower slide bars (36 and 38) and driven thereby to engage and pivot the first lever on the ambient compensator deflector to trip a cut-out switch.  The ambient compensator deflector adjusts both the three phase current trip threshold and the loss of phase current trip threshold, and also affords ambient compensator of each.  A constant ratio relationship between these two thresholds is provided throughout the entire range of current trip threshold settings.  The driver bar moves a first distance for three phase trip and a second shorter distance for loss of phase trip. The ratio of these distances is constant notwithstanding adjustment by the ambient compensator deflector changing the length of such distances.
