Title: Space heating and ventilation systems for buildings
Inventor: FINCH STANLEY GEORGE
IPC: F24F3/14
Filed: 1989-05-23
Abstract: A heating and ventilation unit has a ceramic heat wheel rotatable within a housing between first and second plenums 3,4 through which fresh and stale air, respectively, are forced to pass. As it rotates the heat wheel transfers to the fresh air both the heat generated by a burner 12 (or electric heater), in the second plenum, and also low grade heat contained in the stale air. The burner is housed within a combustion housing 15 by means of which the combustion gases are confined to a generally D-shaped area of the heat wheel. The combustion housing is spaced from the walls of the second plenum to form an annular passage through which unheated stale air passes to cool the walls of the second plenum and purge any combustion gases from heat wheel entering the first plenum. Humidification of the fresh air may be achieved by water sprayed onto the upstream surface of the heat wheel in the first plenum (Fig. 6, not shown). <IMAGE>

Patent GB-2225476-A (GB)
Title: Nuclear reactor
Inventor: SALMON JONATHAN STANLEY
IPC: G21C15/18
Filed: 1989-11-22
Abstract: In a fast nuclear reactor, a conduit (40) is provided between the hot and cold zones (24, 22) of the reactor. Flow through the conduit is controlled by a pressure which depends on a reactor operating parameter. As shown a bleed pressure from the primary pump (18) acts on a jet (46) to prevent flow from the hot to the cold zone. In the event of failure or loss of pressure of the pump, flow through the conduit is permitted, so that the flow assists decay heat removal in the reactor. Bleed pressure from the pump may alternatively act on a flow diode (figure 3, not shown) or an arrangement to provide a gas pressure blocking a weir in the conduit 42 (figure 4, not shown). In other arrangements which respond to loss of electrical power in a reactor component, an electromagnetic valve ceases to operate (figure 5, not shown) or a solenoid valve opens (figure 6, not shown), in each case effecting a gas pressure blocking a weir in the conduit 42.   <IMAGE>

Title: Coin validator with string detector
Inventor: NEWTON MICHAEL EDGAR
IPC: G07D11/00
Filed: 1990-12-07
Abstract: A coin validator (4) has a sensing arrangement disposed after an accept gate (12) for detecting when a valid coin has moved past, and thus causing the triggering of the accumulation of credit. The sensing arrangement comprises a flap (36) which is moved away from its normal position by the coin. The triggering of credit occurs when the flap moves back to its normal position. If the coin is suspended on a string, the flap cannot move back to its normal position and therefore no credit is accumulated.

Patent GB-2262269-A (GB)
Title: Force transmitting mechanism
Inventor: MUNDAY PETER
IPC: G01L5/04
Filed: 1991-12-06
Abstract: A pulley for guiding a flexible cable 16 comprises two separate wheels 42 and 44 which have chamfered peripheries and which are mounted face to face within a casing 40 and forced towards each other by wave springs 48 and 49. Normally the two wheels 42 and 44 rotate as one, so as to form a V-groove pulley. However, in the event of the application of excessive force to the cable 16, the resultant increased radially inwardly directed force causes the wheels 42 and 44 to separate against the resilience of the springs 48 and 49 enabling a small amount of radial inward movement of the cable, thus partially reducing the shock. Also the wheels 42 and 44 make frictional contact with the adjacent casing 40, thus generating friction which retards the rotation of the wheels 42 and 44 and thus the longitudinal movement of the cable. In this way, shock pulses along the cable are minimised or eliminated. <IMAGE>

Title: Compensation type heat sensor
Inventor: TORIKOSHI YASUO
IPC: G01K3/00
Filed: 1992-03-19
Abstract: A pair of temperature detection devices (18, 19) having different heat time constants and an active device (20) having a predetermined bias are connected to one another in series. The bias is set so as to cause the active device (20) to act in a saturated region if the temperature is higher than a dangerous level and to act in a triode region if the temperature is lower than the dangerous level. Furthermore, the temperature detection devices are set so as to cause the voltage generated at the connection contact of the temperature detection devices to be made higher than a predetermined reference voltage if the temperature has been raised to the dangerous level in a case where the temperature is raised slowly or if the temperature is raised rapidly, even if the temperature is lower than the dangerous level. Thus, a constant temperature function and a differential function are realized to detect that a fire has occurred. In an alternative arrangement, Fig 7 (not shown), the series connection of one of the temperature detection devices and the active device is connected in parallel with the series connection of the other temperature detection device and a resistor. <IMAGE>
