Abstract: 827,485. Treating tar. HOLMES & CO. Ltd., W. C., and THOMPSON, R. J. S. May 21, 1957, No. 16021/57. Class 55 (2) Tar from a piston-type gas-holder, to be treated for removal of water and light hydroearbons, is passed continuously through a vessel V wherein it is heated and blown with a gas circulated by a blower B, the gas and vapours of water and light hydrocarbons being removed by a line O to pass through a condenser C into a receiving tank R, and a portion of the circulating gas being bled off from the system through a valve A and metering device M to secure the desired removal of light hydrocarbons. The upper portion of the tank R is connected with the blower B through a valve K which enables the apparatus to be placed under pressure relative to the pressure in a gas main connected by a line G to the gas circulation system. Hydrocarbons collecting in the tank R may be remixed with the treated tar. In a modification the valve A and metering device M may be placed between the blower B and the vessel V and a portion of the circulating gas bled off through line L, thus enabling the valve K to be omitted. Larger amounts of light hydrocarbons may be removed by bleeding off through the valve A all the gas passed through the vessel V, the blower B in this case being supplied only with gas through line G.

Title: Electric control of a boiler heating system
IPC: G05D23/275
Filed: 1965-04-14
Abstract: 1,041,685. Automatic temperature control. HOVAL ING. G. HERZOG & CO. April 14, 1965 [April 21, 1964], No. 16071/65. Heading G3R. In a system in which boiler water is circulated for space heating and in heat exchange relationship with a hot water tank producing a running hot water supply, a thermostatic changeover switch sets a liquid or gaseous fuel burner in operation when the temperature of the boiler water falls below a predetermined value and opens a valve in the supply pipe from the boiler to the space heating when the temperature of the boiler water exceeds the predetermined value and solid fuel firing is in use. A control circuit is described which may be switched to a "solid fuel only" condition to introduce a draught regulator and start a circulating pump for the room heating water. A valve in the circulating system remains closed, however, to prevent room heating until the water in the running hot water tank reaches say 55C. at which temperature a thermostat opens the valve. A room thermostat then controls electrothermal operation of the valve to maintain the room at say 20C. Rise in the temperature of the boiler water above say 75C. is prevented by a boiler thermostat over-riding the room thermostat and opening the valve in the circulating system. If the system is switched to a "burner only (Winter)" state, fuel is supplied to the burner and there is no solid fuel firing or draught. Automatic control of the running hot water and room temperatures is otherwise as for solid fuel firing but the boiler thermostat controls the burner instead of the valve in the circulating system. If, in an attempt to rise room temperature in cold weather the valve opens sufficiently to operate a limit switch, this renders the boiler water thermostat ineffective so that the circulating water temperature can rise up to the limit, say 90C., set by an additional safety thermostate controlling the burner. When the system is switched to a "burner only (Summer)" state, the circulating pump is switched off and running hot water only is provided.

Abstract: 1499246 Electrical connectors W JAGIELSKI 22 April 1976 [22 April 1975] 16380/76 Heading H2E [Also in Division G4] For use in an antitheft alarm device (see Division G4) of the type in which cables attached to articles are connected in a closed circuit with an alarm device, each cable is connected in the closed circuit by means of a plug and socket arrangement which is designed such that when the plug is in the socket the circuit is closed and when the plug is removed from the socket the circuit is momentarily opened and then reclosed. Thus not all the sockets need be occupied. As shown in Fig. 3, the socket 9 consists of a central contact pin 11 mounted inside an insulating body 10 and connected to a contact plate 12 having a terminal portion 13 and a contact tab 14. A second contact plate 15 is insulated at 19 from plate 12 and has a terminal portion 16, a portion which contacts the tab 14 when the plug is not in the socket, and a portion 17 which projects into the interior of body 10. The plug 8 consists of a plastics housing 20 containing an outer contact tube 21 and an inner contact tube 23 separated by an insulating layer 24 which has an annular beading 26 of greater diameter than the tube 21 at its end. Thus, when the plug 8 is inserted into the socket 9, the beading 26 initially raises the contact plate 15 off the tab 14 and then the inner tube 23 contacts the pin 11 and the outer tube 21 contacts the portion 17 of plate 15 thereby connecting the cable in the closed circuit. When the plug is removed, the beading 26 causes momentary opening of the circuit. As shown in Fig. 4, the socket includes contacts 27, 28 and the plug includes two poles 29, 30 separated by an insulating layer 31. When the plug is in position, the contact 28 touches pole 30 and contact 27 is in contact with pole 29 by means of a sleeve (not shown). Upon removal of the plug, a plastics attachment 32 ensures momentary opening of the circuit.
