Title: Opening roller for open-end spinning apparatus
IPC: D01H4/32
Filed: 1979-04-30
Abstract: The invention relates to opening rollers for open-end spinning apparatus, particularly rollers which comprise a body on which is wound a helical coil of metallic wire type card-clothing 14. The roller body comprises two body parts 20,21 secured together in end-to-end relationship, and the metallic wire type card-clothing 14 is formed into a pre-set helical coil which is located on an external cylindrical surface of the body, the end flanks of the coil engaging respectively with two abutments 26,30 one on each of the two parts of the roller body, so that the coil is constrained axially between the abutments in a manner such that adjacent convolutions of the coil are held in abutting relationship. It is preferred to use interlocking card-clothing wire. It is also preferred to make the roller body parts in plastics material, and to secure them together by an adhesive, and in this manner a disposable roller is produced. The specification describes methods of refurbishing existing opening rollers, in accordance with the invention. <IMAGE>

Patent GB-2026359-A (GB)
Title: Apparatus for delivering a stream of abrasive material for cleaning teeth
IPC: A61C3/02
Filed: 1979-07-26
Abstract: Teeth are cleaned by a stream of abrasive-laden air directed towards the tooth concurrently with a stream of water onto the same target area of the tooth, the abrasive being a water soluble abrasive e.g. sodium bicarbonate. A hand-held nozzle unit (3) has a nozzle (4) with an inner tube (8) for the abrasive- laden air and an outer tube (9) allowing water to flow in the annular space between the tubes. The outer tube (9) extends beyond the end of the inner tube (8). The water flows out at a relatively slow rate and is entrained by the jet of air to form a slurry on the tooth surface. The air and water flow is controlled by a footswitch, but a residual air flow is maintained even when the footswitch is off to prevent blockage of the nozzle. A filter removes moisture from the abrasive supplied to the nozzle. <IMAGE>

Title: Filtering apparatus and method
IPC: B01D53/06
Filed: 1979-10-31
Abstract: The apparatus comprises a housing containing a substantially vertical grating 20 (e.g. louvres 22 or a mesh screen) and a substantially vertical microporous gas filter element 12, the said grating and element being spaced apart to provide a zone for the passage of granular filter material 18 downwards therebetween. The housing further comprises a gas inlet and a gas outlet. In operation, a gaseous stream containing particulate contaminants passes through the gas inlet, the grating, the body of granular material 18 and the microporous gas filter element and then out the gas outlet. The particulates carried in the gaseous stream are retained in the body of granular material and upon the upstream face 14 of the gas filter element. The body of granular material is moved through the said zone and across the upstream face of the gas filter element 12 to scour the upstream face 14 and remove the collected particulates, which are carried out of the housing, such that a substantially uniform pressure drop across the apparatus is maintainable during its operation. Element 12 may be of various filter media. Material 18 may be sand or various adsorbent or reactive media. <IMAGE>

Title: Animal identification and estrus detection system
IPC: A01K11/00
Filed: 1980-05-13
Abstract: An animal such as a dairy cow carries a transponder unit which includes a motion sensor.
