IPC: H01R13/66
Filed: 1990-03-08
Abstract: ABSTRACT     Disclosed is an electrical connector having a cavity within its body for the accomodation of surge protection means. The body further  encloses  an  electro-luminescent  source,  as  well  as reflectors and optical light guides for directing light emitted by the electro-luminescent source to a desired area or portion of the body  for  subsequent  emission  therefrom.  More  particularly  is disclosed an electrical connector in which the surge protection means are embodied in a replaceable assembly which is inserted into the body through an aperture.     Means  are provided such that the electrically conductive members internal to the electrical connector are in frictional engagement with aligning electrically conductive members embodied in the replaceable surge protector assembly. Further, fusible link means are provided within the replaceable surge protector assembly such that a short-circuit failure of the surge protection means or a load induced electrical overload will cause physical rupture of the fusible link.     Also  provided  are  optically  reflective  means  in  the replaceable surge protector assembly in order to reflect light from the electro-luminescent source within the body onto the reception ends of the optical light guides,  thereby providing two light paths.     One of the light paths thus provided serves to provide a visible indication external to the connector body of the presence of  electrical  power  when  the  connector  is  connected  to  an appropriate power source,  and the other light path serves to provide a visible external indication of the integrity of the fusible  link,  and  therefore  the  functionality  of  the  surge protection means embodied within the replaceable surge protector assembly.

Title: Laser scanning system for reading bar codes
Inventor: SIEMIATKOWSKI BISH
IPC: G07G1/12
Filed: 1990-03-22
Abstract: LASER SCANNING SYSTEM FOR   READING BAR CODES     ABSTRACT OF THE DISCLOSURE   A laser-scan bar code reader is mounted in a hand-held unit operable in two modes. In one mode the hand-held unit may be mounted in a fixed position in a terminal, in which case the data generated from the bar code reading operation is transferred immediately to the terminal and the reader is powered continuously from the terminal unit. In the other mode, the hand-held unit is separated from the terminal and held manually, in which case the data from bar code reading is stored in a local memory to be later transferred to the terminal when the hand-held unit is again inserted into the terminal. A battery in the hand-held unit is charged when the unit is mounted in the terminal, then powers the hand-held unit while operating remote from the terminal. The power for battery charging and the data transfer are accomplished without direct connections between the hand-held unit and the terminal.

IPC: G06F7/506
Filed: 1990-03-26
Abstract: ABSTRACT OF THE DISCLOSURE     A logic synthesis network for efficiently combining respective bit pairs of first and  second operands to produce respective sum bits and a carry bit associated with the most significant sum bit.   A dummy generator receives the respective bit pairs and generates first and second dummy sum signals, and first and second pairs of dummy  carry  signals.   A  first  dummy  selector  chain selects the appropriate dummy sum and carry signals of all the bits other than the least significant bit, as a function of the state of the first pair of dummy carry signals generated for the least significant bit pair.  A second dummy select chain selects the appropriate dummy sum and carry signals for all the bit pairs other than the least signficant bit pair, as a function of the state of the second pair of dummy carry signals generated for the   least   significant  bit  pair.    Sum  generators associated with each bit pair choose between the selected dummy sum signals from the first and second dummy select chains  in  accordance with  the  state  of  the  carry-in signal associated with the least significant bit pair.          Carry generators associated with each bit pair choose between the first and second pairs of dummy carry signals at the ends of the first and second dummy select chains, again in accordance with the state of the carry-in signal associated with the least significant bit pair.

Title: Device for combined cardiac pacing and defibrillation
IPC: A61N1/362
Filed: 1990-04-04
Abstract: A method is disclosed for combined cardiac pacing and defibrillating with an implanted pacer/defibrillator having sensing and pacing leads connected to the atrium and the ventricle. P-waves and R-waves are sensed, and a V-V timer and a V-A timer are reset if an R-wave is sensed. If an R-wave is sensed during the V-V timer interval, a pacing stimulus to the ventricle is inhibited. If a P-wave is sensed during the V-A timer interval, a pacing stimulus to the atrium is inhibited. If an R-wave is sensed during the V-V timer interval, arrhythmia therapy is provided if an arrhythmia is determined to be present. If the sensed ventricular rate is greater than a selected tachycardia rate but is less than a selected fibrillation rate, then a determination is made whether the sensed atrial rate is greater than a selected fibrillation rate, and if so, the V-V and V-A timers are reset, but if the sensed atrial rate is not greater than a selected fibrillation rate, then arrhythmia therapy is provided. If an arrhythmia is present, the charging of a capacitor commences but if the arrhythmia ceases, the charging discontinues. If the capacitor is charged and the arrhythmia is still present, then a shock is delivered to the heart during a time period that is outside the vulnerable zones of the atrium and the ventricle.

Title: Method and device for rolling coins
Inventor: MCINTOSH JAMES P
IPC: B65B27/00
Filed: 1990-08-23
Abstract: ABSTRACT A method and device for rolling coins has a plastic tube with a first end and second end with a stopper inserted into the second end.  The stopper closes off said end and is tapered to an upper surface.  When it is desired to roll coins, a conventional paper wrapper is rolled into a cylinder and inserted into the tube until an inner end of the paper wrapper surrounds the upper surface and extends beyond the surface towards the second end.  Next, the tube and paper wrapper are filled with coins, the first coin lying flat on the upper surface and the last coin being flush with the first end of the tube. The end of the wrapper at the first end of the tube is then folded, the coin roller is inverted and the wrapper and column of coins contained therein are removed from the roller.  The remaining end of the wrapper is then folded to enclose the coins.  A different size of coin roller is used for each size of coins.  The coin roller can be used repeatedly to roll coins of the same size into cylindrically shaped rolls contained in a conventional paper wrapper.

Abstract: Abstract of the Invention A base for a storage and retrieval machine is disclosed in which the frame of the base comprises a pair of spaced apart frame members having a length generally parallel to the rail upon which the base travels and extending a portion of the length of the base.  The frame members are positioned straddling the rail with the rail projecting upward into the space between the frame members.  A mast is mounted on the base and supports a vertically movable carriage means for carrying objects to and from overhead locations.  The pair of frame members may comprise a pair of L-shaped members each having a downwardly projecting upper wall spaced apart from the upper wall of the other L-shaped member and a lower wall projecting away from the lower wall of the other L-shaped member in a direction laterally of the length of the base.          The base includes first and second trucks located at opposite ends of the pair of L-shaped members.  A wheel is rotatably mounted on each truck and both wheels engage the rail for supporting the storage and retrieval machine as it travels along the rail.  The trucks have a height sufficient to support the wheels, however, the L-shaped member pair are positioned at a lower height than the height of the first and second trucks to permit the low height profile of the base.          An anti-tip bracket is affixed to a foundation adjacent the path of travel of the base, typically at the end of an aisle in which the rail is located.  A lower wall of one of the L-shaped sections engages the anti-tip bracket to hold the storage and retrieval machine from tipping.

Title: Vehicle restraint
Inventor: ALEXANDER JAMES C
IPC: B65G69/00
Filed: 1991-01-10
Abstract: A vehicle restraint employs a 4 bar linkage to lift a restraining member to a position that engages a vehicle thus restraining it at a loading dock. The linkage is upwardly based to hold the unit in an engaging position and may be retracted by using any of a number of mechanical techniques such as hydraulic electric or pneumatic power.  The 4 bar linkage transfers all loading on the unit from the ICC to the frame thus isolating any driven members from overloads.  A secondary hook mounted to the 4 bar linkage is pivotally spring loaded to limit vehicle travel away from the dock and to extend the capture range of the device in the case of ICC's bars that are damaged or mounted at non-standard positions at the rear of the vehicle.

Title: Piezoelectric rotary union system
Inventor: CULP GORDON W
IPC: H01L41/09
Filed: 1991-04-02
Abstract: ABSTRACT OF THE DISCLOSURE A light weight, efficient, and compact piezoelectric rotary union system is provided for joining structures such as space station modules. The system comprises piezoelectric actuators attached to a first structure that engage and rotate a ring attached to a second structure. The actuators position and rotate the ring by non-sliding, smooth walking motion that provides high mechanical efficiency, long life, and negligible electrical noise. Electrical conductors embedded in the ring and the actuator traction surfaces transmit electric currents and signals between the structures. Moderate traction pressure and large contact area substantially eliminate contact heating and associated vacuum welding. The piezoelectric actuators generate relatively large translational forces at relatively low speeds. The absence of conventional rolling bearings eases connection and disconnection of the rotary union. Piezoelectric actuators with integral sensors can control the shape and stress of a relatively light and flexible ring, and can actively reduce or cancel structural vibrations.
