Title: Piston ring lubrication
Inventor: RICHARD GEOFFREY PERCY
IPC: F16J9/06
Filed: 1981-08-14
Abstract: A piston assembly comprises a piston (11) and plurality of piston rings (17, 18, 19, 20). Drillings (29) extending through the piston (11) from the base of the top ring groove (13) to the circumferential surface of the piston between the top and second ring grooves (13, 14) enable gas pressure in the cylinder to be transferred from the top ring (17) to the second ring (18) which takes an increased proportion of the piston sealing load. This arrangement, used in conjunction with a top ring (17) design which facilitates the downward scraping of lubricant towards the sump eliminates, or substantially reduces in volume the standing ring of lubricant formed on the cylinder walls at top ring top dead centre when a conventional ring arrangement is used and results in less production of harmful deposits in the vicinity of the piston rings, and reduced evaporation and degradation of the oil in the engine as a whole. Alternatively, or in addition, the top ring (17) may have transverse slots 31 in at least a part of its outer face to facilitate the transfer of gas pressure (and excess lubricant) from the top ring to the second ring. <IMAGE>

Patent GB-2094502-A (GB)
Title: Air pressure sensors
IPC: G06M7/00
Filed: 1982-03-09
Abstract: The disclosure relates to an air pressure sensor for use particularly in a batched counting apparatus for counting sheets or signatures in a "shingled" stream and comprising an air passage (21) terminating in a probe (17) having an orifice (19) to ride over the surface of the "shingled" stream of sheets. The jet (26, 27) delivers air from a supply line into the passage and branch passage (28) located adjacent the jet contained a floating element (31) which moves up and down the passage in accordance with static air pressure in the passage. The element is arranged to make or break a beam in a photo-electric cell arrangement (12) to operate a counting device. As the probe rides from one sheet or signature to the next, the air pressure in the passage (21) drops and the result in the fall in pressure in the branch passage causes the element (31) to fall thereby triggering the photo-electric cell to operate the counting device. The sensor is extremely sensitive, responding when passing from sheet to sheet of very thin paper and it is capable of operating at high speed. Instead of element (31) and photoelectric cell, a solid state pressure transducer may be used. <IMAGE>

Patent GB-2152143-A (GB)
Title: Pressure release device
Inventor: GOMERSALL RODNEY
IPC: F16K17/14
Filed: 1983-12-23
Abstract: A pressure release device 1 comprises a housing 2 which is secured to the wall 4 of a pressure vessel. A pin 17 is secured firmly within the housing 2 by a nut 22 which is tightened to bring a head 18 of the pin firmly against the O-ring 19, the pin being held in tension. Pressure fluid in the vessel is free to flow through the aperture 5 and the bores 6 and 9 into the bore 10 where the pressure fluid exerts a force on the pin to urge the head 18 of the pin to the left (as seen in Fig. 1). When the pressure within the vessel exceeds a predetermined value, the forces acting on the pin become sufficient to cause the reduced diameter portion thereof to rupture and to expel the head 18 into the chamber 13. This releases the sealing effect of the O-ring and allows pressure fluid to vent to atmosphere through radial passageways 14. The ruptured pin 17 may conveniently be replaced by a new pin to enable the device to be used again as a pressure release device. <IMAGE>

Title: I.c. engine fuel injection supply system
Inventor: SEILER WAYNE HOWARD
IPC: F02M37/22
Filed: 1985-03-27
Abstract: A fuel reservoir 36 from which fuel normally is supplied through an outlet 52, 54, 56 to the inlet side of a high pressure pump from a low pressure supply pump located in a fuel tank contains valving 26, 28 that automatically redirects fuel, which normally is returned from the high pressure pump directly to the fuel tank through the passages 90, 58, 20, back into the reservoir to maintain supply of fuel to the inlet side of the high pressure pump even though the normal supply line 76 is exposed (for short periods) to air and therefore not supplying fuel to the reservoir. The valve 28 opens to the reservoir 36 when, due to a fall in pressure in the reservoir, the pressure of the returning fuel is sufficient to move the valve member against its closing bias. A passage 80 with a restricted outlet 82 to the return passage 20 provides an air vent from the reservoir 36. The check valve 66 prevents syphoning back to the fuel tank. <IMAGE>
