IPC: B29B13/02
Filed: 1985-06-21
Abstract: An apparatus for, and a method of, heating a thermoplastic material in web form in readiness for forming three-dimensional objects therefrom in a thermo-forming process involves (a) advancing the web material intermittently through a heating zone on a belt conveyor without imposing thereon any mechanical stress-inducing physical constraints (such as may be applied by material gripping means), and (b) sweeping the web material with a series of hot air jets which are spaced apart in the direction movement of the material, which extend transversely across the width of the material, and which are reciprocated in that direction in a manner such as to ensure a uniform heating of the web material passing out of the heating zone to a thermo-forming apparatus.

Title: Distributing, processing and displaying financial information
Inventor: HIGGINS GERALD M
IPC: G06F17/00
Filed: 1985-06-28
Abstract: A data processing and communication system distributes and displays financial market ticker, quotation, news and ancillary information via a plurality of stored program controlled work stations. Stock trade executions, quotations and other ticker plant information is communicated in parallel to a hierarchy of system data processing terminals, e.g., those located at area, branch and individual work station locations. Storage media at the several system data processing levels extracts and stores data base information of differing purport and completeness for the disseminated data to support the system work station users. Information characterizing a dynamically changing sub-population of the overall ensemble of market securities is maintained at and becomes immediately available to each work station responsive to the pattern of usage at that specific station. Various derivative tasks, such as security price limit alerts, are user programmable and are activated by the contents of the work station data base. <IMAGE>

Title: Indicating thermal energy of liquid in a tank
Inventor: WALTON PHILIP WILSON
IPC: G01K1/02
Filed: 1986-10-24
Abstract: Apparatus for indicating the quantity and temperature of fluid in a tank 2 such as a domestic hot water tank 2 includes four temperature sensors RT1 to RT4 which are spaced-apart along the outer surface of the tank 2. Each thermistor RT1 to RT4 is connected in series with a light emitting diode L1 to L4 across a battery. Resistors act in combination with the respective thermistors RT1 to RT4 to form a potential divider so that the light emitting diodes L1 to L4 start glowing at a predetermined temperature. Reference diodes L5 to L7 glow respectively with the light intensity of the diodes L1 to L4 for specific temperatures, such as 50 DEG C, 75 DEG C and 100 DEG C. The intensity of the light emitted by the diodes L1 to L4 is compared with the intensity of the light emitted by the reference diodes L5 to L7 to indicate the thermal energy of the water in the tank 2. <IMAGE>

Title: Improved system for refrigeration
Inventor: LAVIE RAM
IPC: F25B25/02
Filed: 1989-10-27
Abstract: An improved system for refrigeration of the vapor-composition cycle type is described. The system comprises a compressor, a condenser, expansion valve and evaporator, wherein an adsorber reactor and cooler are provided between the evaporator and compressor, and a desorber reactor is provided between the compressor and condenser. the characteristic feature being that the pressure ratio across the compressor is in the range of 1.5 to 20. Heat is transferred by means of said adsorber and desorber reactors containing a solid or liquid adsorbent having the capability of preferentially retaining one component from the stream entering into the reactor. The cooler dissipates the adiabatic compression heat and the heat of absorption through the assistance of the adsorbent bed. Using this refrigeration system, the improvement in the yield will be in the range of 3% to 40% depending on the parameters used in the cycle and the amount of external heat used. <IMAGE>
