Title: Cold-gas machine
IPC: F25B9/14
Filed: 1970-12-30
Abstract: 1335855 Cold-gas machines PHILIPS GLOEILAMPENFABRIEKEN NV 30 Dec 1970 [2 Jan 1970] 61761/70 Heading F4H In a cold-gas machine, that is either a coldgas refrigerator or a cold-gas engine, which comprises two piston-like members 2, 3 reciprocable in a cylinder 1, an annular seal 16 of synthetic resin is disposed to inhibit the flow of working medium through the gap between the expansion space 15 and the compression space 10. If medium flows from the compression space along the seal 16 into the gap 14, contaminant present in the medium will freeze out on the cold walls of the gap. To prevent this, a duct 18 opens out of the wall of the piston-like member 3 (shown as a displacer) or the wall of the cylinder at a point which is at all times between the planes containing the axial extremities of the seal, the duct communicating with a buffer space 19 which communicates with the compression space through a second duct 20 incorporating a non-return valve 21 opening towards the compression space. By suitable choice of the volume of the buffer space 19 it is possible to avoid substantially entirely any return flow of medium along the seal.
Patent GB-775313-A (GB)
Abstract: 775,313. Grates. CHISHOLM W. W. Sept. 28, 1955 [Oct. 19, 1954], No. 30025/54. Class 126 The bars 5 of a grate terminate short of one end 4 of the grate to leave a gap 6 large enough to allow the passage of incombustible material too large to pass between the bars of the grate. A shelf 7, carried below the grate, restricts the escape of fuel during normal combustion. In a domestic boiler stove, the Fig. 4, the shelf 7 may be carried by the boiler, or the escape of fuel may be prevented by a baffle projecting from the boiler wall above the gap, or formed by a projecting part of the boiler.

Title: Apparatus for producing an image of a three-dimensional object on a television receiver
IPC: G06T15/00
Filed: 1978-10-19
Abstract: To display on a TV raster a perspective view of a faceted 3-D block from e.g. computer data 3, including the block geometry, observation point and e.g. colour, lighting, etc, a priority processor provides data in each facet, arranged in priority order, highest towards the observation point. Thence projection calculator 5 determines the shape of each facet as projected in the scanning plane. Raster lines through every apex of a facet divide it into trapezium shaped elements, coded in 7 and subdivided in 9 to describe segments of bars made up of groups of raster lines, terminated by the inclined facet edges, the priority order of the facets being maintained in the coding. In coordinate calculator 11 the segment terminations for the current scan line are calculated, allowance for priority being made in priority generator 13 and video signals corresponding are formed in 15. <IMAGE>
Patent GB-2012987-A (GB)
Title: Measurement and dispensing of constant weight portions of material
IPC: G01G11/08
Filed: 1978-12-08
Abstract: An apparatus for dispensing material, especially but not solely tobacco, in portions of predetermined weight from a stream of irregular density comprises a variable speed feed system 10 which passes the material through a measuring region 11 where its density is monitored, and the feed speed is automatically adjusted to compensate for measured variation in the density to provide discharge of portions of predetermined weight from the feed system at regularly spaced time intervals. The relative separation positions of the portions may be calculated by determining the weight of each portion from both the density information and the feed speed, separation of the portions by a knife 15, being effected when the separation position previously calculated reaches the end of the feed system. <IMAGE>

Title: Pipe Couplings
IPC: F16L19/08
Filed: 1979-03-16
Abstract: A pipe coupling comprises a coupling body 1 having an externally screw-threaded sleeve 2 provided with a bore 3 into which an end of a pipe 4 is fitted. A sub-assembly of nut 5, collet 6, and back-up washer 7 is provided, the collet 6 being retained in the nut 5 by means of a retainer member 20 which has a turned up portion 22 forming a screw-threaded engagement with the threads in the nut 5.

Patent GB-2041789-A (GB)
Title: Separating particles from a liquid
IPC: B01D35/06
Filed: 1980-01-31
Abstract: In a method and apparatus for separating particles suspended in a liquid from the liquid, a flow of the liquid is passed through a filter bed (7) of ferromagnetic bodies which acts as a coarse filter to trap the larger particles in the flow. The filter bed (7) is arranged within a truncated core between the poles of an electromagnet (9). To cleanse the bed and flush out the trapped particles a wash liquid is passed through the bed (7) and the electromagnet (9) is energised to levitate the bed to thereby allow the wash liquid to remove the particles. The liquid flow from the coarse filter can be passed to a high gradient magnetic separator (8) at which remaining small particles in the flow are filtered magnetically. <IMAGE>

Title: Method for separation of germinated seed from non-germinated seed
IPC: A01C1/02
Filed: 1981-01-29
Abstract: Seeds are coloured black before germination and then germinated, whereupon the germinated seeds or the non-germinated seeds are sorted out by measuring the reflection of the individual seed. Non-germinated seeds will not reflect any light because of the dull black colour, while germinated seeds, usually having white germs, especially if they are germinated in dark, will reflect enough light to form the basis for a separation. The reflection measurement may be made with a photocell and a light source in a measuring chamber.
