Patent GB-2089086-A (GB)
Title: Gaming machines
IPC: G07F17/32
Filed: 1981-11-16
Abstract: A gaming machine has a housing 10 for location in a predetermined, upright condition for normal operation of said machine. One or more display windows 22 are provided in the housing, and a reel assembly 14 has a plurality of reels 16 with symbols 20 on their circumferences for display at the windows. According to the invention, the reels (16) are each rotatable about an axis (18) extending upwardly when the housing is in its predetermined, upright condition. The symbols (20), which may be animals or humans, for example, are upright when the reels are arranged for rotation about the upwardly extending axis. This enables one or more stroboscopes (80) to be incorporated in the machine for flashing to illuminate intermittently the part of each reel displayed at the or each window of the machine as the reels rotate, to give an impression of movement of the symbols. <IMAGE>

Title: Dry storage cell for radioactive material
IPC: G21C19/06
Filed: 1982-02-10
Abstract: In a dry storage cell for irradiated nuclear fuel or other highly active waste, cooling air flow is by natural draught in heat exchange with fuel containing canisters housed in channels. To inhibit corrosion by ensuring that the temperature of the air flowing over the canisters does not fall below the dew point when heat generation by decay has fallen, a fraction of the heat energy transferred to the cooling air is recirculated to the air upstream of the canisters. Recirculation of heat energy is effected by recirculation of a fraction of the hot air from downstream of the canisters.

Title: Hot water heating installation
Inventor: MOLBAEK JENS JORGEN
IPC: F24D19/10
Filed: 1983-09-23
Abstract: In a hot water heating installation comprising a heat generator (1), circulating pump (4) and radiators (6, 6a, 6b) regulated by thermostatic valves (7, 7a, 7b), wherein the supply temperature is variable, a regulator (11) is influenced by the supply and return temperatures and so changes the supply temperature that the difference between the supply and return temperatures is kept at a predetermined desired value. The desired value need not be constant but may be predetermined as a function of the return temperature. An electronic regulator or a differential thermostat may be employed as the regulator (11). In this way, the efficiency of the heating installation can be improved in dependence on the load. <IMAGE>

Patent GB-2135757-A (GB)
Title: Fluid control valve
Inventor: HOMES GRAHAM DENNIS
IPC: F02M59/36
Filed: 1984-01-31
Abstract: A fluid control valve includes an axially slidable valve member 22 which is coupled directly to the armature 29 of an electromagnetic actuator by a valve stem 26. The valve member 22 has a head 23 which is drawn into contact with a seating when the device is energised. In this position a step defined between the valve member and the stem is exposed beyond the body 20 containing the valve member. The step is engaged by a spring abutment collar 35 slidable on the stem and engaged by a return spring 36 which biases the valve open and an anti bounce spring 39. The opposite end of the spring 39 is connected to the stem and the spring 39 is compressed during movement of the valve member and armature to the open position after the collar has engaged the body. The spring then returns the valve member to its normal open position. <IMAGE>
Patent GB-2137029-A (GB)
Title: Switching Control Circuit for DC/AC Inverter
Inventor: JOHNSON FREDERICK OWEN
IPC: H02M7/521
Filed: 1984-03-06
Abstract: The control circuit includes a pair of switching circuits 14, 16 which measure the anode-cathode voltage and the current flowing through respective control thyristors 22, 24 of the inverter thereby to inhibit a gate control signal responsive to an on-off command signal when (i) the anode-cathode voltage falls below a predetermined value, (ii) the current flowing through the thyristor exceeds a predetermined unsafe level, or (iii) upon the occurrence of an inadequate power supply to the gate by circuits. The turn-off and turn-on delay periods of the thyristors may be complementary in duration thereby to assure complete turn-off of one thyristor before a second thyristor conducts in order to decrease the likelihood of short circuits across the poled thyristors. When the gate control triggering signal is inhibited in response to one of the detected unsafe conditions, the gate driver inhibit is preferably sustained for a duration to allow normal turn-off in response to the on-off command signal thereby to permit re- initialization of the power circuits of the gate driver. Also, sustaining of the inhibit condition permits sufficient time for a master control device to recognize the detection of the unsafe condition and to alter its state of operation accordingly. <IMAGE>

Title: Electromagnetic caliper brakes
Inventor: MYERS PHILIP E
IPC: F16D65/18
Filed: 1984-04-30
Abstract: Two electromagnetically actuated friction brakes (14, 14') are disposed on opposite sides of a relatively thin armature disc (11) of low reluctance material. The poles (21, 26, 27) of one electromagnetic friction brake (14) are polarized oppositely from the aligned poles (21', 26', 27') of the other brake (14') to cause the flux created by each brake to thread axially across the armature disc (11) and interact with the flux created by the other brake so as to produce relatively high braking torque the two brakes are not only attracted to the disc but to each other. Such polarisation may be achieved by connecting a dc voltage source to respective coils (22, 22') of the brakes (14, 14') in reverse fashions (see Fig. 4). As shown, the poles are defined by respective studs received in holes in an oblong block (30) of friction material. <IMAGE>
