Abstract: A fastener for a reverse fed panelboard circuit breaker is taught. Briefly stated, a resilently deformable pivoting member is disposed between side barrier fins in a two pole panelboard breaker. A pin at one end of the fastener is placed through a screw hole which is contained in the panelboard and disposed between the side barriers of the panelboard breaker, with the fastener rotatably urged towards the breaker so as to, when fully rotated causes the breaker retention tab to be urged against the panelboard retention hook and also for the fastener to lay against and come in contact with the edge of the panelboard breaker thereby preventing removal of the breaker without first removing the fastener.

Abstract: A method of introducing gas into a substrate processing chamber. The method of introducing gas into a substrate processing chamber comprises the steps of filling a gas metering area with the gas to a first predetermined pressure, closing the area to maintain the area at the first predetermined pressure and opening the area to the substrate processing chamber. When the area is opened to the substrate processing chamber, the gas inside the area will expand into the chamber to provide the chamber with a second predetermined pressure.

Abstract: Problems in shutting down the compressor in a vapor compression air conditioner in response to high pressure, low pressure and frozen refrigerant conditions are eliminated in a protection circuit that includes a contactor coil to control the power supply to the compressor. The use of a semiconductor switching configuration in the protection circuit provides for disconnecting the power to the compressor under fault conditions and for ensuring that the power connection to the compressor remains disabled until the conditions which initially triggered the protection circuit are corrected.

Abstract: A thermal and magnetic trip unit for a multi-pole circuit breaker includes a thermal structure having a bimetallic element and one or more heater elements. Each of the heater elements and a portion of the bimetallic element is generally "U" shaped defining a conductive path which extends from one leg of the U to the other leg. The heater elements and bimetallic element may be configured in parallel to reduce the level of current flowing through the bimetallic element and thus increase the current level at which the bimetallic element will trip the breaker. Alternatively, the heater elements may be configured in series with the bimetallic element, by inserting electrical insulators between the bimetallic element and each of the heater elements and connecting the various "U" shaped elements using a connecting bus which connects the second leg of one element to the first leg of the next element.

The strap attachment unit being attachable to a strap and the musical instrument attachment unit being attachable to a musical instrument.

Abstract: A circuit breaker contact arm (56) contains a straight elongate through-slot (112) that runs generally lengthwise of the contact arm and is closed at both lengthwise ends. Adjacent each slot, a respective side wall (106, 108) of a cross bar (58) contains a bent slot (114) having a knee (116). A respective cylindrical blow-open pin (118) passes through all three of these slots. A small helical coiled spring (120) occupies the contact arm through-slot and is compressed between the blow-open pin and the end of the contact arm slot that is proximate a cross bar/contact arm hinge pin (110). The spring is laterally confined by the adjacent side walls of the cross bar so as to remain in the contact arm slot about which the contact arm swings. The spring acts between the blow-open pin and the contact arm to bias the blow-open pin in a direction away from the cross bar/contact arm hinge axis.

Abstract: A polymer film drumhead having indentations in the surface, the indentations placed strategically by size, number and placement near the periphery of the drumhead to control the vibrational characteristics and the overtone content of the drumhead when struck.

Abstract: A lid handling system employs a lid alignment assembly for aligning lids randomly placed on a rotating input disc, a lid separation assembly for separating lids spinning on a pair of horizontal spin bars into a counted stack, a vacuum pickup assembly for picking up a counted stack of lids, a pick and place assembly for transporting and placing stacks of lids into trays having upwardly bent side members, and a conveyor for conveying filled trays toward a carton.

Abstract: The invention relates to a multiple-row egg breaking and separating machine in which the egg contents and egg shells are passed adjacent one another through an inspection station at which the contents of the egg can be rejected because the shell or contents are contaminated, defective or abnormal. The present invention is particularly useful for high-speed breaking operations, yet still allows the inspector to view all the parts of the eggs for possible rejection of the egg contents. The present invention is particularly suited for automatic scanning of egg shells and contents, and eliminates possible U.S. Food and Drug Administration (FDA) objections to prior art multiple-row egg breaking machines.

Abstract: An apparatus for heating substrates having a frame forming a vacuum chamber, a heater, a lift mechanism and a lift arm. The lift arm has a general "Y" shape and is located in a groove in a top heat transfer surface of the heater. The lift arm extends out of the groove at a lateral side of the heater and is connected to the lift mechanism.

Abstract: An apparatus for orienting and feeding articles or parts that is particularly adapted for use in an automated assembly system and has a feeder bowl that includes a helical internal track which terminates at the upper edge of the bowl adjacent to an annular feeder ring mounted for selective rotational movement around the feeder bowl to receive parts P therefrom. A control circuit including a stationary camera positioned above the annular feeder ring acts to control rotational movement of the annular feeder ring by an operatively connected motor in order to bring successive portions of the annular feeder ring into a predetermined vision field of the camera in order that correctly oriented parts can be differentiated by incorrectly oriented parts and a signal then provided to a pick-and-place robot to remove the correctly oriented parts. A sweeper bar is positioned at a selected location to urge incorrectly oriented parts off of the annular feeder ring and back into the feeder bowl for recycling.

Abstract: A multiplexing circuit which rapidly shares a single rate generator among up to 16 different motors. The circuit utilizes an addend memory block with n-bit by m-deep memory structures. Each memory address represents a particular stepper motor in the system. An axis scanning state machine 9 drives the memory structure address lines in a circuitous manner. At each memory address visit, the state of the circuit is re-established based on information stored from the last visit. The addition operation is performed to change the accumulator value in memory block 102. Any possible edge event is noted by edge detector 11. An edge produces a step and position monitor count. The axis-scanning state machine then moves on to the next address representing the next motor. The axis-scanning memory address influences memory structures throughout the device including accumulator value in memory block 102, addend memory values 12, device configuration 13, and step monitor counter 14.

Abstract: An apparatus for assembly of laminated components to a card base includes a main platen secured to a pair of precision linear bearings to support the card base. Rows of vacuum holes in the platen secure the card by suction effect. A removable track location key at one edge of the main platen includes detent positions engaged by a track location lock, so that the main platen may be locked at any of those positions. A transfer platen extending parallel to the main platen is pivotally secured to the machine base. The transfer platen also includes rows of vacuum holes to hold component strips by suction effect. The transfer platen is rotatable from a loading position to the main platen to deliver a component strip to a precise position on a card secured on the main platen. The method of the invention includes placing a card substrate on the main platen and securing it thereto with vacuum suction.
