Patent GB-564704-A (GB)
Title: Improvements in gas generators charged with solid combustible fuel
IPC: C10J3/80
Filed: 1943-02-04
Abstract: 564,704. Gas - producers. KALLE, K. T. Feb. 4, 1943, No. 1879. [Class 55 (i)] One or more air inlet pipes and one or more gas discharge pipes surrounding them have air and gas discharge mouths so disposed that the flow of air is substantially parallel to the gas discharge pipe or pipes to restrict the reaction zone. In the example, air is introduced through a pipe 1 and gas is withdrawn through slits 17 in a concentric pipe 2 so that localised oxidation and reduction zones 5 are formed in the fuel bed, the gas being drawn out through pipe 9 by an internalcombustion engine. The suction provided by the engine creates a partial vacuum in pipes 2 and 7 which acts on diaphragms 10 and 11 attached to pipes 1 and 2 respectively, so that on increased demands by the engine and increased vacuum, the pipes 1, and 2 are drawn into the fuel bed against the action of springs 14, 15, and a larger portion of the grating 17 is exposed to the fuel bed enabling an increased amount of gas to be withdrawn and increasing the size of the combustion zone. The displacement of the pipe 2 ensures that the grating 17 is cleared by friction against the pipe 7.

Patent GB-1363391-A (GB)
Title: Torque limiting coupling
IPC: F16H35/10
Filed: 1973-01-15
Abstract: 1363391 Positive clutches TWIN DISC Inc 15 Jan 1973 [31 Jan 1972] 2012/73 Heading F2C  In an overload release clutch wherein torque transmitting balls 30 carried by slots (34) in a carrier disc 33 normally engage recesses 10a, 20a in driving and driven clutch discs 10, 20 urged together by a spring 13, the balls 30 ride out of the recesses 10a, 20a on overload and move circumferentially into reset recesses 10b in the driving disc 10 which, during clutch disengagement, is held at a predetermined distance from the driven disc 20 by spacing blocks 36 on the carrier 33. The spacing blocks 36 abut a shoulder on a driving shaft 1 and normally project into recesses 10e in the driving plate 10. When, on overload, the balls 30 ride out of the recesses 10a, 20a the driving disc 10 is moved axially away from the driven disc 20 against the bias of the spring 13. The following circumferential movement of the balls 30 rotates the carrier 33 and spacing blocks 36 relative to the driving disc 10 so that when the balls 30 engage the reset recesses 10b the spacing blocks 36 abut the surface of the driven disc 10 and hold it at a predetermined distance from the driven disc 20. The spacing between the discs 10, 20 permits free relative rotation between the discs. An abutment 38 rotatably fast with the driving disc 10 is engaged by the spacing blocks 36 in the clutch disengaged position to prevent movement of the carrier 33 and balls 30 beyond the reset recesses 10b. To reset the clutch the driving member is rotated reversely or the driven member rotated forwardly whereupon light springs 10c in the reset recesses 10b urge the balls 30 into engagement with the recesses 20a in the driven disc 20. Further rotation of the driving or driven member cams the balls 30 out of the reset recesses 10b and moves them circumferentially into the driving recesses 10a. The driving disc 10 is splined to a sleeve 7 which is itself splined to the driving shaft 1. The torque at which the clutch disengages on overload is adjusted by adjusting the position of the sleeve 7 and thus the pressure of the spring 13. A seal 23 between the sleeve 7 and driven disc 20 prevents dirt entering the clutch. In Figs. 17-19 (not shown) the driving and driven recesses are unequally spaced circumferentially around the driving and driven discs to permit clutch engagement in only one relative circumferential position of the driving and driven members. In Fig. 20, the driving, driven and carrier discs 10<SP>1</SP>, 20<SP>1</SP>, 33<SP>1</SP> are made from sheet steel and the spacing blocks are replaced by portions bent from the carrier disc. A belleville spring 50 urges the discs together and studs 51 limit the rotation of the carrier disc 33<SP>1</SP> relative to the driving disc 10<SP>1</SP>.

Patent GB-875577-A (GB)
Title: Improvements in and relating to automatic machines for the return of empty bottles
IPC: G07F7/06
Filed: 1960-01-22
Abstract: 875,577. Article-delivery apparatus. WIEGANDT, K., and WIEGANDT, W. Jan. 22, 1960 [June 3, 1959], No. 2361/60. Class 27 A machine for receiving empty bottles on which a deposit has been paid comprises a conveyer 15 movable between a fixed upper position in which the bottle is received and a lower end position dependent on how full the collecting chamber is, and a device 24 for testing the dimensions of inserted bottles and, if the bottle is correct, bringing the conveyer and a deposit return device into operation. The conveyer, in its upper position, is held tilted upwardly by latches 19 engaging a pin 17 and is raised and lowered on slides 8 by a belt 10 wound on a motor-driven pulley 12 or passing over a small idler pulley to a motor-driven pulley arranged conveniently in the casing. In use, the customer opens a closure in the casing and places the bottle on the conveyer, the bottle setting spring-loaded feelers 24 arranged along its length so that a circuit is prepared through sets of contacts 25, 26. When the closure is closed, it is locked and the motor drives the pulley 12 so that the belt unwinds and allows the conveyer to descend under gravity. At the same time the deposit return device is operated. When a lever 20 on the conveyer reaches the bottom of the container or the top of the pile of bottles already in the container, the latches 19 are released and the conveyer tilts downwardly to deposit the bottle. The belt continues to unwind from the pulley 12 until it is fully unwound, when it winds up again in the opposite direction and takes the conveyer up with it. Rollers 29 on the conveyer engage cam surfaces 33 to tilt the conveyer back into receiving position and re-engage the latches 19 and the polarity of the motor is changed so that when it is next switched on it runs in the opposite direction and first of all unwinds the belt. Subsequently, the closure is unlocked to allow insertion of the next bottle. The electrically-operated parts may alternatively be operated by mechanical means. A bottle-receiving machine is also described in which an endless chain carrying a number of bottle compartments runs over sprocket wheels at the top of a casing and hangs freely down from the sprockets.

Title: Hydraulic control system for a loader
IPC: F15B11/20
Filed: 1970-01-20
Abstract: 1,245,376. Hydraulic motor control circuits. TYRONE HYDRAULICS Inc. Jan.20, 1970 [June 25, 1969], No.2636/70. Heading F1P. [Also in Division E1] A hydraulic system for a loader comprises two fluid delivery means or pumps 55, 131, and a valve means 63 to direct fluid from both pumps 55, 131 to the lifting rams 33 of the boom of the loader when the pressure in the rams is below a set amount, and from pump 55 to the lifting rams and from pump 131 to the bucket rams 43 when the pressure in rams 33 is above the set amount. As shown line 53 leads from pump 55 to manually actuated three way valves 69, 71 which are in series and which control the flow to rams 43 and 33. Valve 63 is switched from a position in which line 135 from pump 131 is connected to line 53 to a position in which line 135 is connected to line 101 leading to rams 43 in dependence on the pressure sensed through line 65, in line 53, the pressure in line 53 being that of rams 33 when valve 71 feeds fluid thereto. Valve 127 in line 65 can be used to stop the automatic switching of valve 63. In a modification valve 127 is replaced by a pair of pressure responsive valves in parallel so that valve 63 can be responsive to two different pressures for different types of soil &c. being loaded. Switching of valve 63 is prevented by spool valve 119 during the dumping cycle of the bucket. Pump 131 may be connected directly to valve 63 or through a valve 137 as shown. Valve 137 directs the flow into line 133 leading from pump 129, or to valve 63 in dependence on whether the pressure drop through constriction 141 is low or high. Line 133 leads to steering valve 25. Pumps 55, 129 and 131 are driven by the engine of the loader of a speed proportional to the speed of the engine. If the pressure in line 53 should become too high valve 107 is actuated to apply the brakes and disconnect the drive to the tracks or wheels of the loader. Valve 107 may be actuated electrically.
