Filed: 1957-03-30
Abstract: 830,483. Screwing-up nuts. GIRLING Ltd. June 30, 1958 [March 30, 1957], No. 10477/57. Class 83 (3). A power-driven nut-runner comprises a nutengaging member 28 having a radial gap 30 and spanner-shaped through-bore 29, rotatably mounted between plates 31, 32, having a gap 33 to allow the member to be applied laterally to a nut, said member being driven through alternative-drives, whereof one rotates the member continuously, whilst the other stops the member when the gap 30 is in line with the gap 33. As shown, a compressed-air motor drives a sleeve 13 in which is keyed a shaft 15 carrying a combined gear-and-clutch 19, 21, the gear engaging an elongated pinion 20 which meshes with a gear 23 carrying the second clutch member 22. Gear 23 is connected to member 28 through gear-train 25-27. To drive a nut, clutchparts 21, 22 are engaged by a hand lever pivoted at 17 and acting on a restriction 18 of shaft 15. When the nut is set, a friction-drive slips, or the motor stalls, and the shaft 15 is then raised to disengage the clutch. Gear 23 is then rotated by pinion 20 until a gap, produced by missing teeth in gear 23, comes opposite the pinion, the gaps 30, 33 then being in alignment to allow the member 28 to be removed laterally from the nut. In a modification, the drive from the power-unit may include a dog-clutch, disengaged by means which engage a second clutch in the alternative drive, the second clutch being disengaged by a projection on the nut-engaging member when it reaches a predetermined angular position. In a further modification, the supply of current or compressed-air to an electric or air motor may be taken through two valves or switches in parallel, one of the valves or switches being switched off by a projection on the nut-engaging member, and only switched on again when the other switch or valve is switched off by the operator; the nut-engaging member being rotated to the desired angular position.

Patent GB-1363096-A (GB)
Title: Valve assembly controlling filling of a receptacle from a liquid  feed line
IPC: F16K21/18
Filed: 1972-03-28
Abstract: 1363096 Valve assemblies J G THOMSON 28 March 1972 [6 April 1971] 10637/71 Heading G3P An apparatus for preventing the generation of static electricity, and therefore the risk of explosion, when filling a tanker with petroleum, comprises a valve assembly which provides an  initial rate of flow which is less than that at which static electricity is generated but which increases to a maximum once the end of the apparatus has become submerged beneath the rising level of the petroleum. In one embodiment. Fig. 2, the valve assembly is mounted in a filling line 11 and comprises a spoked main ring valve 25, a pilot valve 40 for controlling the flow of liquid to the underside of a piston 26 forming part of the main valve, a shut-off valve 80, and a liquid level sensor 15. The pilot valve member 48 is attached to a diaphragm 45 and normally closes a passage 111. The cut-off valve comprises a spool 101 attached to a diaphragm 90. In use, liquid entering at A trickles through restricted passage 21 and passes through line 11 to the tanker. As the liquid level rises in the conical portion 63 of the sensor 15, the pressure on the underside of the diaphragm 45 is increased thereby causing the valve member 48 to move to an open position. Liquid also entering at B can now flow through passages 56, 110, groove 103, and passage 111 to the underside of piston 26. As the piston is lifted the main valve 25 is moved to  its fully open position. Once the liquid level in the tanker closes a port 98 in the line 11, the pressure on the right-hand side of diaphragm 90 increases, thereby causing the spool 101 to move to the left. In this position, the spool diverts liquid from passage 110 through groove 104, into passages 107 and 108, and thence to the topside of the piston, whilst simultaneously venting the underside of the piston through passage 111, groove 103 and passage 105. The main valve 25 moves to a shut-off position in consequence. In another embodiment, Fig. 3, each side of the diaphragm carrying the pilot valve member 123 is vented to atmosphere. However, as one of the vents 139 is closed by the rising level of liquid, a vacuum is generated in the chamber 126 by virtue of liquid flowing past a U-tube 135. This causes the pilot valve to actuate the main valve. A flexible diaphragm 155 serves to reduce flow turbulence.

Title: Improvements in Apparatus for Washing Beer Kegs or Like Containers
Inventor: RUDDICK MAURICE
IPC: B08B9/08
Filed: 1967-03-07
Abstract: 1,153,251. Washing beer kegs. BURNETT & ROLFE Ltd. 31 Jan., 1968 [7 March, 1967], No. 10708/67. Heading B8T. [Also in Division G1] An automatic beer keg washing machine includes a washing head 1 applied to the bunghole 2 of a keg 3, with a drainage duct 5 and a washing liquid supply duct 4 connected via a projecting spigot 7 to a spear 8. A measuring device and a timing device are provided to ensure that the correct predetermined volume of cleaning fluid is introduced into the keg during the washing cycle, and that the rate of introduction is rapid enough for efficient cleaning, an alarm being given if the introduction of the predetermined volume of liquid takes longer than a predetermined time. In the circuit diagram, Fig. 1, liquid flow pipes are represented by double lines, pneumatic connections by chaindotted lines and electrical connections by single full lines. At the start of the cleaning cycle a liquid measuring tank 12 is empty, and solenoid operated valves 39, 44 and 48 are de-energized and closed, the tank 12 being thus cut off from a compressed air supply 37 and open to atmosphere through pipes 33, 35. Valves 10 and 15 are held closed since the air supply is shut off by valves 44, 48 respectively. The empty tank 12 is pushed upwards by a spring 20 about a pivot 17, an arm 24 holding a switch 26 closed. An electronic sequence controller 42 energizes and opens the valve 48, compressed air thus being supplied to and opening the valve 15, allowing liquid to fill the tank 12 from a supply at 13. The spring 20 is depressed under the increasing weight of the tank 12 until the arm 24 closes the switch 25 causing the controller 42 to de-energize the valve 48, closing the valve 15. The controller 42 then energizes the solenoid-operated valve 39, which opens, allowing compressed air from the supply 37 to reach the valve 34, which changes over to lead compressed air into the tank 12. The solenoid-operated valve 44 is energized, causing air to be supplied to and open the valve 10, enabling the washing liquid to be forced out of the tank 12 under pressure through pipes 11, 6 and into the keg through the washing head 1. Simultaneously an electrical timer incorporated in the controller 42 starts to operate for a set time interval, the alarm 54 being caused to operate if the predetermined quantity of liquid has not left the tank 12 within this time. When this quantity of liquid has left the tank 12, the tank has been sufficiently raised about the pivot 16 by the spring 20 to cause the arm 24 to close the switch 26, the sequence controller then de-energizing the valve 44 causing the valve 10 to close, and opening the tank 12 to atmosphere through the pipe 35 by de-energizing the valve 39 and reversing the valve 34. The whole cycle may be repeated after the washing liquid is expelled through the duct 9 by air or steam supplied either through the duct 6 or through a third duct in the head 1.
