Title: Machines for introducing fluids into containers
IPC: B08B9/08
Filed: 1980-08-15
Abstract: A machine is provided for introducing a cleaning fluid or beer into a keg (14) having a fitting provided with a valve (15). The machine comprises a filling head (1) having a valve (4). The head (1) is positioned adjacent the keg valve (15) with a sealing ring (16) therebetween. A probe (3) is moved upwardly by piston and cylinder device (6a, 6) from the illustrated position to open the keg valve (15). Valve (4) in head (1) is moved downwardly from the illustrated position to allow cleaning fluid or beer to flow via a conduit (12), an annular passage (11) and the keg valve (15) into the keg (14). During filling, air flows out of the keg (14) via a path comprising a bore (20) of the probe (3), a tube (21) and a float valve (22). When the keg (14) is full, the fluid starts to flow through the above-mentioned path. This closes the float valve (22) and a device (24) is responsive to the resultant back pressure to cause the probe (3) and valve (4) to be returned to their illustrated positions. Liquid (shown shaded) is expelled in the direction of arrow (30) by compressed air supplied at (27) to clear the machine. <IMAGE>

Title: Central Heating Control System
IPC: G05D23/275
Filed: 1980-12-22
Abstract: A control system is provided for controlling the operation of a wet central heating system of the type in which water can be pumped around a space heating loop and optionally a domestic hot water loop. The control system includes switches 30 and 31 which are turned on so as to permit hot water if demanded to be supplied to the space heating and domestic hot water loops. If the cylinder thermostat 32 or the room thermostat 33 or both are closed, the boiler 1 is fired for a heating cycle as conventional and also as conventional the heated water is circulated by the pump 11 around either or both loops. However, after a heating cycle even when both thermostats 32 and 33 are open, the control arrangement is such that hot water is still circulated around the space heating loop. This is because the pump 11 is still caused to operate as it receives current on lines 46 and 42 because a relay contact RL2''' is closed. Similarly the space heating zone valve 13 is still open because it receives current on lines 52 and 45 since relay contact RL2'''' is closed. Thereby the boiler is enabled to operate more efficiently as the residual heat stored in the boiler's thermal capacity is pumped to the radiators. The pump is caused to operate at a first speed during heating and at a slower speed after the heating cycle so as to circulate water in to the system to dissipate boiler heat content and prevent overheating. <IMAGE>

Title: Method of producing thermoplastics extrusions using scrap materials
IPC: C08J11/06
Filed: 1979-06-11
Abstract: Fully cured scrap rubber is chopped and then granulated, after which the granules are mixed with granulated thermoplastics material in a heated barrel of an extrusion device.

Title: Process of and apparatus for conditioning freshly roasted coffee
Inventor: CHAMPION RONALD CHEYNEY
IPC: A23F5/16
Filed: 1982-10-11
Abstract: Coffee is conditioned by being fed into a container 1 the atmosphere of which is flushed by inert gas fed through inlet valve 2 to allow the carbon dioxide content of the atmosphere in the chamber to drop to a predetermined level e.g. six percent as measured by a monitor 6. At the same time, gas is evacuated through exhaust 18. When said level has been attained, the flushing and exhausting are discontinued until the proportion of carbon dioxide in the atmosphere has risen to a second predetermined level, e.g. eight percent. These operations are then repeated until the coffee has been maintained in the container for a sufficient length of time for a required proportion of carbon dioxide to occlude from the cells of the coffee, which can be discharged, with inert gas being fed into the chamber at the same volumetric rate as the rate of discharge. <IMAGE>
