  • Patent number: 5187466
    Abstract: The method of producing an oscillating circuit on a label capable of being deactivated consists essentially of moving two surfaces of a capacitor together by a heated rod. Due to the heated rod dielectric material melts and the two capacitor surfaces become short circuited. Upon application of an appropriate current/voltage source, this short circuit is removed by burning or melting away to form a crater-like hole in a thinner surface of the capacitor. This produces a state of the label which allows, in a later deactivation step, a positive short circuiting. When the capacitor surfaces are moved together, the electrical connection between the two surfaces connects the crater forming source. Thereafter, a short circuit between the surfaces appears only when the label is passed through a deactivating station.

  • Patent number: 5184538
    Abstract: Shrimp and other food products carried on a plastic modular conveyor belt are efficiently cooked at atmospheric pressure in the presence of saturated steam protected by a confining receptacle from dilution by insulating air. The steam condenses by transfer of cooking energy, the condensate dropping downwardly in the receptacle by gravity. By passing products through the constant 212 degree F. saturated steam zone residing at the upper portion of the cooking receptacle, the belt speed and distance through a modular cooking compartment control the cooking time for uniform production. The steam is replenished through a proportional flow valve to replace only that amount of steam expended in cooking. Thus, temperature is sensed at a cooler position under the saturated steam cooking zone where temperature is typically 190-200 degrees to detect variations of the amount of steam condensed in exchange of heat in cooking the product, and to proportionately control the flow of replacement saturated steam.

  • Patent number: 5184315
    Abstract: A data processing keyboard system is provided wherein data and command signals from the keyboard are entered by two or more successive keystrokes. At least two operation modes serve to change the entry command assignments to the keys, thereby affording a large number of selections from a few keys. This makes available from the comprehensive capability of present day computers large numbers of keyboard accessible commands. Also surprisingly then this invention can replace a normal QWERTY typewriter keyboard with most of its functions by a set of only three, four, seven or nine keys. Thereby alphabetic characters, decimal digits and a store of computer command entries may be processed with each entry requiring two or more strokes of the computer keyboard keys. Functional commands such as spacing return or shift can be intermixed with the choice of data characters. Means for shifting from a computation mode to an alpha mode of computer operation may be provided.

  • Patent number: 5182458
    Abstract: A more efficient wind power generation system is afforded by extending tower heights to several hundred meters to operate wind catching rotors and generators aligned with the wind direction at various levels along the tower. With multiple vertically cascaded wind generators and higher velocity winds at higher elevations greater power is produced as a system characterized by a small footprint. This is particularly enhanced by a single mast construction, which is supported by a dynamic guy wire tensioning system to accommodate varying lateral forces primarily caused by the change in direction of wind loads on the tower. The mast is built from modular sections connected together at articulated joints, between which the various rotors are stationed.

  • Patent number: 5176599
    Abstract: Muscular development of an athlete is achieved for increasing the starting acceleration and stroke speed when an athlete initiates a movement stroke such as a punch from a boxer's arm, throwing a baseball pitch or kicking a football, etc. by the means and method of this invention. Thus, the initial movement of the athlete is restrained with an external force of predetermined magnitude which is released in response to the athlete's movement overcoming the restraining force. Thus, those muscles are developed which are used in initiating motion so that they deliver greater initial acceleration to attain higher stroking speed which is converted to an impact blow of greater force. An exercise machine for such muscular training provides the initial but releasable restraining force by means of two separable magnetically attracted members having the predetermined initial force adjustably varied by introducing a variable air gap distance between the magnetically attracted members.

  • Patent number: 5176700
    Abstract: This invention provides an improved surgical instrument, namely sponger-dissector forceps particularly adapted for laparoscopic intra-abdominal surgery such as gall bladder removal. Thus, sponges are retained locked in place without manual force upon the distal end of a substantially cylindrical hand held assembly by means of an internally mounted ratchet mechanism. In one embodiment sponges are retained by a 7 shaped distal end on a reciprocating 2 mm diameter rod disposed in a 10 mm diameter cylindrical housing member. The ratchet locks the reciprocating rod in place against movement in the distal direction, and thus holds sponges clamped in place at the distal end. The ratchet lock is releasable by a catch release button. The rod is manually reciprocated to engage and clamp a sponge by a finger operated slide member. The sponge is thus firmly held in position for blunt manipulation including direct hemostasis pressure on small blood vessels or for sponging to keep the surgical region dry.

  • Patent number: 5172461
    Abstract: By means of this invention electrical resonant circuits, specifically resonance labels having a capacitor and a coil on a dielectric are produced for reliable deactivation by means of an electrical discharge between the capacitor surfaces. Heretofore aluminum threads produced from the material of the capacitor surfaces is not supported in place so that it can break with handling and vibration and cause reactivated of the resonant circuit leading to a false alarm in the safety system. According to this method a plurality of conductive bodies of a size in the micron range, e.g. copper dust is introduced in the dielectric so that a spark from discharge of a capacitor will cause an electrically conducting connection between the capacitor surfaces, which is embedded in a thread like shape in the dielectric. By using copper dust, an alloy is formed with the aluminum which evaporates during the spark discharge such that the thread produced has a substantially larger ductility than pure aluminum.

  • Patent number: 5172729
    Abstract: The expansion hose specifically for power steering plants of automobile vehicles includes an outer pressure hose with a high lateral volume expansion connected to an inlet side end piece and an outlet side end piece and an inner flexible hollow body as well extending coaxially thereto and which is connected at the inlet side to a nipple plug of the inlet side end piece and extending freely up into the outlet side end piece and into its outlet channel whereby its outer diameter is less than the surrounding outlet channel. A reverse flow of the pressure medium into the space between the outer pressure hose and the inner flexible hollow body takes place through an annular gap formed thereby and the pressure medium flows into this space through radial portholes formed in axial distances distributed in the inner flexible hollow body. In comparison with known expansion hoses simplification is achieved by a doing away with a throttle located in the center of and within the expansion hose.
