Title: Improvements in the manufacture of insulating panels for portable containers
Inventor: LOPEZ DONALD EMILIO
IPC: A45C11/20
Filed: 1984-06-13
Abstract: A composite flexible plastics sheeting for use in making a thermally insulated container is made by backing a plastics sheet 14 faced with a reflective metal foil 12 is rendered capable of being made up into a liner for a thermally insulated container by bonding the plastics layer thereof to a larger layer 16 of plastics so as to leave a non-metallised margin 18 surrounding the edge of the foil. The latter is then used for making seam welds between panels so that the foil is substantially continuous over one surface of a prismatic liner and the resultant product used to make a heat-insulating container thermally insulated container. <IMAGE>

Title: Refrigeration systems
Inventor: VANA JOHN H
IPC: F25B41/04
Filed: 1984-09-26
Abstract: A refrigeration system includes a pressure-responsive switch 100, sensitive to pressures in a refrigerant supply line 22, 24, 111 extending from a condenser 20 to an evaporator or evaporators 32, 34 or in a receiver 28 communicating with the supply line 24, which switch 100 operates to open a normally closed solenoid valve 56, to dump hot gas from a compressor discharge line 18, into the receiver 28. The switch 100 acts whenever pressure falls below a predetermined minimum value. The refrigeration system can include both the pressure switch 100 and a sensing device 46a arranged to detect "flashing" in the refrigerant supply line and to act on the same valve 56, with the switch 100 adapted to override the sensing device 46a whenever the pressure in the refrigerant supply line drops below the minimum pressure for which the switch 100 is preset, without regard to whether flashing has begun to develop downstream from the switch 100.   <IMAGE>

Patent GB-2150247-A (GB)
Title: Fluid flow couplings
Inventor: BRAKE ARTHUR LEIGHTON
IPC: F16L37/23
Filed: 1984-12-20
Abstract: A fluid flow coupling, particularly for pneumatic lines, comprising a first element (3) and a second element (31) each of which contains a valve retracting member (13, 36) having a flange which engages a spring-loaded valve member (16, 38) which, when the two elements are interengaged, abut each other to provide a through-flow path through the coupling. When the path is open the two valve retracting members engage to close a venting path (74) which is opened when the two elements come to be separated. The two elements are held together by balls (46) engaging in a groove (22) and held therein by a sleeve (47) which carries a second sleeve member (56) having teeth (61) which engage with teeth (62) on a sleeve member (23) carried on the element (3). When the teeth are engaged the coupling can only be moved towards the engaged condition and to release the coupling it is first necessary positively to manually draw back the sleeve (56) to disengage the ratchet teeth. It is thus not possible to disconnect the coupling inadvertently and it is not possible to disconnect the coupling when the space between the two halves of the coupling contains fluid under pressure. <IMAGE>

Title: Torsional vibration damper with rotation-rate-dependent friction device
Inventor: MACKERT NIKOLAUS-DIETER
IPC: F16F15/12
Filed: 1986-01-20
Abstract: In a torsional vibration damper having an under-load system 1 and an idling system 12, the output part of the under-load system is connected with a common hub 8 through a toothing 6,7 with play in the circumferential direction corresponding to the range of action of the idling damper. Between the output part of the under-load system and the common hub an additional friction device 11 is provided having a relatively high friction value which can be brought into action in dependence upon the rotation rate through centrifugal weights above the idling rotation rate. This arrangement avoids the so-called load change knock which occurs when at high torque and at high degrees of irregularity the range of action of the idling damper is run through too fast. <IMAGE>

Title: Shaft couplings
Inventor: KRUDE WERNER
IPC: B60K17/22
Filed: 1986-01-21
Abstract: A joint between a pair of longitudinal members, one of which is formed of fiber-reinforced plastic having fibers wound at a fiber angle  alpha  taken relative to a longitudinal angle of the member, and the other of which is made of metal, e.g., steel.

Title: Photoelectrically-controlled faucet structure
Inventor: CHIO TIEN-CHAI
IPC: E03C1/05
Filed: 1987-07-01
Abstract: A photoelectrically-controlled water faucet is designed to be convertible from an automatic mode to a manual mode, or vice versa, with ease, and water flow passage can be properly selected by actuating a conventional control knob so to effect the adjustment of either the flow volume or the temperature of the mixed hot and cold water flowing therethrough. A rotable, apertured mode - selecting tube 40 is positioned within an apertured temperature - regulating sleeve 30. An electro magnetically operated valve member 50 co-operates with one end of the tube 40. For automatic operation, the tube 40 is rotated to a position in which flow from hot and cold water inlets must flow to the faucet outlet past the valve member 50, which for manual actuation the tube 40 is rotated to a further position in which the flow path by-passes the electromagnetically operated valve. <IMAGE>

Title: Differential phase shift, frequency shift, keying and dual tone generation
Inventor: WONG HEE
IPC: H04L27/00
Filed: 1988-03-04
Abstract: A circuit includes the following features: a 1200 baud 4-phase differential phase shift keying (DPSK) modulator, a 300 baud frequency shift keying (FSK) modulator, a dual tone multi-frequency (DTMF) generator, and 2100/2225 Hz answer tone generators. …<??>The DPSK modulator utilizes time-domain filtering techniques using a sequence of signals D0-D3. It includes a spectrum controller S1-S3, M7-M12 that shapes the in-band frequency spectrum and attenuates the adjacent channel frequency components to eliminate the conventional requirement of band-pass filters after the modulator. The FSK modulator also utilizes a spectrum controller which, during each data transition, sends out six intermediate frequencies to smooth the frequency changeover. DTMF generation is accomplished by multiplexing two sine-wave counters into a DPSK sinewave look-up ROM. By varying the duty cycle of the multiplexing control signal, the DTMF generator provides a digital pre-emphasis function that boosts the amplitude of the high-band frequencies as referenced to the low-band frequencies. The circuit is implemented digitally Figs 1a - 1h, a digital DAC being provided for converting the modulated signal (parallel) to a serial bit stream. …<??>The modulated signal in analog form is available after a low cost low pass filter. …<IMAGE>…
