Title: Oil cleaner
Inventor: WHITESIDE RICHARD BARTLEY
IPC: B01D29/07
Filed: 1984-12-03
Abstract: An oil cleaner comprises a generally cylindrical housing 1 having a closed base, an open top and a central core 6 integral with and projecting upwardly from the base. A filter element 16 of the toilet roll kind surrounds the core 6 and a gasketed top cover 5 closes and seals the open top. The top cover is secured in place by a bolt 18 extending downwardly into threaded engagement with the core 6, the core having a passageway 11 for oil to be filtered entering the housing through the base. This passageway 11 communicates with a further oil passageway 9 in the bolt 18 which opens into the interior of the housing above the filter element 16 whereby in use oil can be transmitted under high pressure to the top of the filter element. <IMAGE>

Title: Clutch mechanism used in a commodity meter
Inventor: MICHAELIDES CONSTANTINE
IPC: G01F15/00
Filed: 1985-01-31
Abstract: The assembly of a gas meter of the kind having a top casing (13) and an external index casing (14) is made difficult by the necessity of providing a drive passing through the casing wall to the index mechanism. According to the invention the measuring mechanism is first put together with a gear box (12) and drive shaft (11). A magnetic coupling (16, 16 min ) is mounted on the casing (13) but not yet placed on the meter. The driving part (19) of a clutch mechanism (18) is secured to the shaft (11) and the driven part (27) secured to the magnetic coupling (16, 16 min ). The driving part comprises a cylinder (19) releasably held retracted by a pin (20) engaging behind a shoulder (21). With the cylinder (19) thus retracted the casing (13) is mounted on the meter. When the meter is first run the rotation of shaft (11) releases the pin (20) so that the clutch (18) engages.

Patent GB-2159588-A (GB)
Title: Seal construction and method
Inventor: HARTMANN HANS J
IPC: F16J15/12
Filed: 1985-04-25
Abstract: A seal ring (10) for use in exhaust systems. The ring results from axial deformation of a knitted tube of stainless-steel wire mesh that has been filled with vermiculite granules. The vermiculite granules fill the knitted tube (16) in the course of knitting, and the granules are compressed into retention by flattening (17) and accumulating the filled knitted tube, as on a take- up reel (24). For each manufactured seal ring, a predetermined length is cut off, then helically coiled (Fig. 3, not shown) and axially deformed to ring contour; and the compressed ring is subjected to heat to at least partially cure the vermiculite. A final die-compression disposes of any small expansion which may have occurred in the curing process. (See Fig. 4 for process flow diagram). <IMAGE>

Title: Domestic back boiler
Inventor: SULLIVAN RICHARD JAMES
IPC: F24B1/183
Filed: 1985-09-12
Abstract: A back boiler has a hollow back portion 11 and a plurality of upright hollow fins 12 projecting forwardly of the back portion and communicating therewith. The fins 12 are widest at the rear and taper towards their front edges 14, and are sloped forwardly in the upward direction to define therebetween a plurality of forwardly sloped flues 15. By this means flames and hot gases which tend to rise vertically are wedged against the sides of the forwardly sloping flues which converge towards the rear, thereby improving heat transfer to water contained in the fins. The flues 15 have a substantially constant cross- section along their length to reduce any "venturi" effect. <IMAGE>

Abstract: PCT No. PCT/GB86/00043 Sec. 371 Date Nov. 20, 1988 Sec. 102(e) Date Nov. 20, 1988 PCT Filed Jan. 23, 1986 PCT Pub. No. WO86/04268 PCT Pub. Date Jul. 31, 1986.Apparatus for collecting and discharging waste material comprises peripheral rows of teeth arranged on rotatable cylindrical shafts. The teeth on each shaft intercalate so that an entrapment zone for waste material is formed thereat during contra-wise rotation of the shafts. The teeth in each row pass through respective slits formed between the blade edges of rectilinear scaper blades placed between the rows and resting on the shaft. The scraper blades remove waste material from and between the teeth for discharge from the machine. To prevent the waste material being caught by cutting action between the leading faces of the teeth passing the scraper blades edges the magnitude of the angle formed at any time between those leading faces and the blades edges as the teeth pass through slits, has a value determined by the shape of the leading faces of the teeth and blade edges of the scraper blades so that the inducement of frictional engagement in relation to the materials being handled is never sufficient for a biting or cutting action to ensue.
