A electrical board game comprising a power source one terminal of which is connected to a plurality of movement indicating means such as light bulbs 17 or electromagnetically operated spinners each associated with a direction indicator 26, each movement indicating means 17 being connected in use in series with a selected plurality of contact points at locations 18' in the form of apertures 11, and a marker in the form of a probe 25 connected in series with the other terminal of the power source through a first switch 20, such that when the probe 25 is placed in one of the locations 11 and the switch 20 closed one of the movement indicating means such as the lights 18 associated with the bulbs 17 is activated thereby indicating the next move of the probe 25. The locations 11 may be connected in a plurality of series circuits to the light bulbs 17 by a printed circuit which may be interchangeable. The light bulbs 17 may vary in number and may be covered with domed translucent covers 18 on the control panel or may be covered by interchangeable translucent or transparent "read-out" panels as shown in Fig. 8 (not shown). The probe 25 may be a wander lead which is a sliding fit into each of the apertures 11 to make contact at the respective contadt 18' and may be connected through the switch 20 by a push button second switch 21. The board, which is mounted on a frame work 13 may be adjacent to the control panel 14 or it may be separated by a panel setting out the rules or the board may be at a slight angle to the horizontal with the control panel at a much steeper angle adjacent the board (as in Fig. 8, not shown). The game consists of moving the probe 25 from the top right hand aperture 12, the player and computer making alternate moves, usually to an adjacent aperture, the computer moves being indicated when the first switch 20 is closed, as indicated by the "computer" position on the control panel, with the winner (or loser depending on the rules adopted) being the one who moves the probe into the bottom left hand aperture. Further probes may be provided so that players may compete, when the first switch 20 is replaced by a single pole multi throw switch.

Abstract: 1,226,452. Automatic temperature control. CONTROLS CO. OF AMERICA. July 22, 1968 [Aug. 11, 1967], No.34804/68. Heading G3R. A refrigeration system comprises an expansion valve 16 operable to control refrigerant flow from a condenser 12 to an evaporator 14, a valve actuator 36, 40 responsive to an electrical signal to control the flow in dependence on the temperature of a thermistor 50 exposed to respond to either or both the temperature and physical state of the refrigerant. Valve actuator comprises a bi-metal plate carried on the end of needle valve 26, heated by a winding 36 and urged by spring 40 into contact with a metal ring 46. Thermistor 50 is suspended by its leads 52, 60 to contact the refrigerant and the leads 52, 60 pass into a thermally and electrically insulating terminal assembly 56. Thermistor 50 is connected in series with batteries 66, a manual or bi-metallic switch 68 which also controls the compressor 10, a variable resistor 86 to set the overall flow of refrigerant, and heater winding 36. A switch 88 shunting resistor 86 permits operation at a higher level. A high value resistance 82 in parallel with thermistor 82 increases its sensitivity. Thermistor 50 has a negative temperature co-efficient so that current through it rapidly increases on closing switch 68 thereby causing bi-metal winding 36 to heat bi-metal plate 38 and open the normally closed expansion valve 16. When excess refrigerant is passed through the evaporator 14 the thermistor 50 responds immediately to the change to liquid state, its resistance increases and the valve 16 tends to reclose. A normally open switch 84 controlled by a temperature sensitive element 85 exposed to evaporator 14 shunts thermistor 50 whenever there is the danger of evaporator freeze up. In Fig. 2 (not shown) two thermistors are strapped to the inlet and outlet ends of the evaporator so that their self heating effects are reduced. Increase in outlet temperature of the evaporator is detected by the outlet thermistor which causes valve 16 to open. Increase in inlet temperature is sensed by the inlet thermistor which causes an increase current flow in a circuit in parallel with the valve actuator thereby tending to close valve 16. The inlet and outlet thermistor therefore tend to maintain the temperature differential across the evaporator constant. A switch permits just the inlet thermistor to control valve 16 to maintain the evaporator temperatures and pressures constant.

Abstract: 1,233,379. Making diesel fuel. AMF Inc. 11 Dec., 1968 [29 Dec., 1967], No. 59104/67. Heading C5E. Diesel fuel is made from crude oil by a process comprising heating the crude, at 56, to form a residual oil and vapours, indirectly cooling the vapours, at 34, to condense diesel fuel only, combining the residual with the crude, and disposing of the remaining vapour. The apparatus operates as follows: crude oil is fed at 10 to a heat exchanger 14 and thence by a pump 26 to the condenser 34, passing over a surface 36 and via 38, 44 to a standpipe 24 for recirculation via 26, or for storing or recombining with the feed via 52. Heated crude is drawn off at 46 and passed via 64 . . . 70 to an electrically heated kettle 56, being further preheated by hot residual oil in a pipe 72 passing from 112 to 114. Vapours from the kettle 56 rise through ports 84, 86 and condense as diesel fuel on the inner surface of 36, being drawn off from 88 by syphon 90 for. delivery by the heat exchanger 14 to product outlet 98. Light vapours from the passage of the crude over surfaces 36, 72 are taken off at 42 and 77 respectively to an outlet 102. The temperature in the condenser is maintained at about 250‹ F. by temperature-responsive means 54 which control a valve 52 operative to release warm crude from the cooling circuit, a supply valve 18 being controlled by liquid-level responsive means 22 in the pipe 24. The temperature of the crude in the kettle 56 is maintained at about 525‹ F. by temperature-responsive means 58 controlling a supply valve 60.
