Abstract: ABSTRACT OF THE DISCLOSURE          An air release valve, used in a system containing liquid with gas above it, has a float chamber connected to the system and containing a float which normally closes a primary orifice leading through a vertically movable spring-loaded piston to an upper chamber.  When the piston is raised by gas pressure in the float chamber to open the primary orifice, a seal pad, spring-mounted above the piston, closes a secondary orifice from the top chamber to atmosphere until the increased pressure in the top chamber moves the piston down to open the secondary orifice.  When liquid entering the float chamber causes the float to rise, closing the primary orifice and lifting the piston, the seal pad closes the secondary orifice, trapped gas lowers the liquid and float, and the primary orifice opens.

Abstract: Abstract of the Disclosure A suture forming surgical tool particularly useful in attaching an epicardial pacer electrode to the heart.  The tool has an elongate body and a manually operable plunger slidable in the body.  The electrode is releasably secured to a distal end of the tool. In a first portion of its travel, the plunger acts on a pair of pusher wires that each drive lengths of malleable sutures through tubular dies that have curved central bores which impart curvatures of essentially predetermined radii to the sutures.  As the curved sutures are ejected from the dies they pass through the adjacent heart tissue and form circular loops which securely attach the electrode to the heart.  In a second portion of its travel, the plunger detaches the electrode and its lead wire from the tool.

Abstract: ABSTRACT OF THE DISCLOSURE          A multi-function, pyrolytic self-cleaning oven thermostat for regulating bake and clean temperatures and oven door unlatching.  The thermostat includes separate bistable and creep-action switch mechanisms actuated by a single thermally expansive hydraulic wafer responsive to oven temperature changes.  An axially movable partially threaded shaft, rotatable between two end positions, is provided for operator adjustment of the temperature switching point of the bistable mechanism.  At one end position of the rotative shaft a minimum baking temperature switching point is provided while at the other end position a maximum temperature switching point is established for pyrolytic self-cleaning of the oven.  A generally linearly increasing temperature range of bistable mechanism switching points is provided from the minimum to the maximum temperature switching point end positions.  A portion of the temperature range not suitable for baking or pyrolytic cleaning and corresponding to a sector of shaft rotation between the two end positions may be utilized as an off position separating a larger sector of baking temperature shaft positions and a smaller self-cleaning shaft position sector. The maximum temperature switching point end position is adjustable to facilitate clean temperature calibration.  The creep action switch mechanism is utilized during a self-cleaning operation to preclude oven door unlatching above a predetermined temperature.

Abstract: ABSTRACT OF THE DISCLOSURE A coloration method for textiles using chemically formed gels is disclosed.  The method provides considerable freedom for making color designs and precise pattern prints, and can be used with conventional dyeing and printing equipment.  In one embodiment of this invention, gelled regions are formed by separately applying a gelable composition and a gelling agent composition to a textile material, and then over-dyeing the material, the gelled regions serving as dye resist regions. In another embodiment of this invention, lateral ink spread typically occurring as a result of printing or imparting patterning to the textile material is reduced by incorporating a dye into either the gelable composition, the gelling agent composition or both compositions, such that when one of the compositions is applied over the other composition, gelled print or pattern regions are formed, lateral spreading of the compositions is inhibited and, accordingly, excellent print or pattern definition is achieved.

Granted: 1982-05-11
Abstract: Abstract Channel efficiency in a communications link between a controller and multiple portable units is increased by polling the active units and a set number of inactive units in a sequence where a "poll" consists of sending the binary coded address of the portable unit.  The stream of trans-mitted data bits is only interrupted by a response from the portable unit, then resumed at the end of the response or a given portion of the response.  During the reception of the response, certain other types of messages can be sent out by the controller.  Portable responses can be automatic re-sponses as to status, etc., or can be data initiated by the operator of the portable unit keyboard and stored in the portable unit memory until "armed" by the operator, then automatically transmitted to the controller when the portable unit address is received.

Abstract: ABSTRACT OF THE DISCLOSURE         In a gear finishing or other machine having a base, a table support mounting a reciprocal table having a head stock and a tail stock for supporting a workpiece gear or spline to be finished, a pedestal on the base mounting a motor-operated trans-mission and a depending machine head mounting a power-driven abrasive honing, or other type finishing gear rotatable upon a horizontal or vertical axis, the table support or head being relatively adjustable with respect to the other to bring the Workpiece teeth into operative position with respect to the teeth of the finishing gear.  The improvement which comprises a first gear train connecting said transmission to said finishing gear for rotation thereof at a predetermined speed.  A drive spindle is journalled through said head stock adapted for axial drive engagement with the workpiece gear to be finished.  A second gear train interconnects said transmission with said drive spindle for rotation at a predetermined speed.  A compensating support device mounts a portion of the second gear train to provide for continuous drive thereof during relative vertical adjustments between the table and head.  The first gear train has an accumulated backlash therein as does the second gear train.  A backlash compensator is mounted on the table and connected to the second gear train for equalizing the backlash in both trains for the initial positioning of the finishing gear teeth with respect to the workpiece teeth.  The compensator further functions to modify the accumulated backlash of the second gear train, alternatively advancing and retracting the teeth of the workpiece gear with respect to the teeth of the finish-ing gear, either manually or automatically.  Thus, on feed of the workpiece in one direction, one side of the teeth of the finishing gear engages one side of the workpiece year teeth, and upon feed in the opposite direction, the opposite sides of the finishing gear teeth engage the other sides of the workpiece gear teeth.

Abstract: ABSTRACT     An optical focusing system is provided for accurately focusing a wafer surface, thereby enabling the production of sharp microcircuit images.  Accurate focusing is achieved despite non-parallel and non-flat wafer surfaces, despite differences in reflectivity of different portions of the wafer surface, and despite changes in environmental conditions such as temperature during system operation.      The system comprises a full aperture focus detection apparatus, a kinematic lens positioning apparatus, and a kinematic wafer chuck differential leveling or positioning apparatus.  The full aperture focus detection apparatus detects the extent to which a wafer surface is out of focus with respect to the image plane of a projection lens, and produces an amplified differential signal having magnitude and polarity indicative of the extent and direction, relative to the image plane, that the wafer surface is out of focus.  When the center of the wafer surface is to be focused and is positioned along the optical axis of the system, the amplified differential signal causes the kinematic lens positioning apparatus to focus the center of the wafer surface by moving the projection lens a distance and direction corresponding to the magnitude and polarity of the amplified differential signal.      The kinematic wafer chuck differential leveling or position-ing apparatus provides for differentially leveling the chuck at three selected off-center locations.  When a point on the wafer surface corresponding to one of these three locations is to be focused and is positioned along the optical axis of the system, the amplified differential signal causes the kinematic wafer chuck differential leveling or positioning apparatus to focus that point by raising or lowering the chuck at exactly that point.
