Abstract: MANAGEMENT CONTROL SYSTEM             ABSTRACT OF THE DISCLOSURE          The present invention is a computer control system for a glass factory having a plurality of individual section glassware forming machines, commonly known as IS machines.  The glass factory control system preferably comprises four micro-processor systems, respectively responsible for overall factory control, overall shop control, individual shop control and individual section control. In this regard it is noted that a factory comprises a plurality of shops, each including an individual IS machine.  At the most general level, a microprocessor called the factory supervisory computer performs such functions as scheduling jobs, controlling inventory, forecasting sales, determining fuel availability and cost, providing job status, performing IS machine simulation and providing maintenance information.  Generally, the supervisory computer coordinates the operations of the entire factory and is not concerned with the detailed operations of the IS machines.  At the next level, another microprocessor called the console computer stores and manages all job history files, provides shop status information on demand and collects selected production data.  Generally, the console computer is responsible for monitoring the operations of each of the shops and for retaining and modifying production and operating information.  Each shop computer performs such functions as controlling a stacker motor, monitoring temperatures, storing section status information and storing job timing information in nonvolatile storage.  Generally, each shop computer is responsible for the operation of the individual sections of the IS machine under its auspices.  At the most specific level, each section computer controls the glassware forming mechanism of the associated individual section.  Different levels of operator control analogs to the levels of the control system are provided.  In organization, the supervisory computer is connected to the console computer and to the various production support and monitoring systems common to the factory.  The console computer is connected to each of the shop computers and also to the various production support and monitoring systems common to the factory.  Each shop computer is connected to a plurality of section computers under its auspices and to the monitoring systems of the associated shop.  Each section computer is connected to its associated individual section and to monitoring systems specific to the associated section.

Abstract: NUTATING SNAP ACTION SWITCH MECHANISM                       Abstract An electrical switch actuation mechanism is described.  Principally useful for keyboard switch data entry devices, the mechanism operates by means of cammed surfaces to produce a generally nutating, rocking snap action.  Depression of the key button moves a stem with cam surfaces on it which contact cammed surfaces on a rocking plate member.  The action produces a first rocking motion in a first axis followed by second and third combined snapping and rocking actions about second and third axes in that plane, but at different angular orientations from the first action.  A hypothetical vertical axis con-structed through the plane of the rocking member will nutate or process in a generally orbital fashion about a central pivot point.  The motion of the plane of the rocking plate may be easily coupled to any of a variety of transducer devices be they contacts, capacitive, optical or inductive.

Abstract: EASY OPEN CAN END WITH PULL TAB HAVING RETAINED TEAR STRIP    WITH STRESS RELIEF MEANS     RALPH J. STOLLE      An easy open can end having a retained tear strip extending diametrically part way across the can end defined by a score line of non-uniform depth, and a graspable pull tab, which may include fulcrum elements, one on either side of the center line of the pull tab, secured to the tear strip.  Lifting of the pull tab initiates tearing of the score line which may be continued to form an opening in the can end.  When the pull tab is pressed inwardly to a stored position against the can end, if desired, the tear strip doubles back upon itself to form an arcuate portion in the tear strip lying beneath the surface of the can end which operates to relieve stress and prevent metal fracture of the tear strip which could cause the strip to become separated from the can end.

Abstract: PENSTOCK FISH DIVERSION SYSTEM            ABSTRACT OF THE DISCLOSURE       A  fish  diversion  system  for  a  penstock housing a hydroelectric turbine employs large area screens to shunt fish to a bypass conduit above the turbine.    The  screens  are  disposed  generally lengthwise of the penstock and inclined upwardly at a  shallow angle  to  maximize  water  flow  velocity along  the  screens  while  minimizing  the  approach velocity normal  to  the screens.   Fish and debris are  thus  swept  along  the  screens  rather  than impinged on them.  One embodiment uses two screens set end to end.  The upstream screen can be tilt-able  for  cleaning.   A  second  embodiment  uses  a unitary elliptical  screen  in  a  cylindrical  pen-stock.  The bypass conduit is sized and positioned to minimize bypass water  flow volume while main-taining sufficient volume and velocity to discharge fish  from the  upper  portion of the penstock.   A funnel-shaped bypass manifold connects the penstock to the bypass conduit.

Abstract: Title:  Dual Stage Thermostat & Electric Space Heating System Inventors: Gerald Dunnigan Ardeshir Bounder ABSTRACT OF THE DISCLOSURE     A dual stage thermostat for an electrical space heating system in which there are two micro-switches connected in parallel and operated by a common bimetallic strip.  The first switch when closed connects a heating element to a power supply through a diode which reduces by half the power applied to the element.  The second switch when closed connects the heating element directly to the power supply. The temperature at which the second switch opens is set about 1.5°F. lower than that at which the first switch opens.  Thus, as the room temperature approaches the desired temperature, the heater element is switched from full to half power, producing less temperature overshoot and saving energy.  The thermostat may be used with any standard two wire heater.

Abstract: TITLE OF THE INVENTION:            OPTHALMIC SURGICAL INSTRUMENT WITH BEVELED TIP AND METHOD FOR MAKING SAID INSTRUMENT            ABSTRACT OF THE DISCLOSURE:     A surgical instrument for ophthalmic use comprises a rigid outer tubular member and a rigid inner tubular member which is axially slidable within the outer tubular member. The outer tubular member has a closed distal end which is beveled at an oblique angle with respect to the longitudinal axis of the outer tubular member. The outer tubular member is also provided with a distal side wall opening, serving as a cutting port, which occupies at least part of the area covered by the distal beveled portion of the outer tubular member. The inner tubular member has an open and tapered distal end terminating in a cutting edge which is movable into the beveled end of the outer tubular member in order to sever material drawn into the cutting port. The instrument is useful for cutting near the retina since the cutting port is located very close to the instrument tip, and is also advantageous in that the beveled tip can be used to elevate or dissect intraocular material prior to cutting. Premature blade wear is avoided by providing a counter-bevel on the cutting portion of the inner tubular member in order to provide a spacing between the cutting edge and the interior edge of the cutting port. Also disclosed is a method for making the instrument in which an oblique cut is formed through the inner and outer tubular members at the same time.
