Title: Yarn feeder and changer unit
IPC: D04B15/60
Filed: 1980-09-05
Abstract: A yarn feeder and changer unit for a knitting machine comprises a number of adjacent yarn feeders 40 any one of which can be moved from a yarn trapping position to a yarn feeding position with an upward component of movement from below the needle level by pivotal movement about a horizontal axis 38, and forward movement over the needles by a sliding component of movement.

Patent GB-2061615-A (GB)
Title: Composite conductors for integrated circuits
IPC: H01L29/49
Filed: 1980-09-16
Abstract: The composite conductive structure is formed on an insulating substrate (14) on which is provided a patterned layer of polycrystalline silicon (15a) overlying the layer of insulating material (14). A composite conductor (17) is provided which includes a core (11a) of a refractory metallic material and a layer (18) of a silicide of the metallic material surrounding the exposed surfaces of the core (11a). The composite conductor overlies and is in registry with the patterned layer (15a) of polycrystalline silicon. A layer (19) of silicon dioxide overlies the exposed surfaces of the composite conductor (17) and the patterned layer (15a) of polycrystalline silicon. The structure is produced by depositing a first layer polycrystalline silicon, a layer of a refractory metal (eg Mo) and a second layer of polycrystalline silicon, heating to cause the metal to react with the silicon to form a layer of silicide and then oxidising the outer surface of the silicide. Outer layers of unreacted polycrystalline silicon may be etched off before the oxidation or may be oxidised together with the outer surface of the silicide. The refractory metal may be Mo, W, Ta, Pt, Pd or alloys thereof. <IMAGE>

Patent GB-2062877-A (GB)
Title: Method and device for detecting leaks from pipelines
IPC: G01M3/18
Filed: 1980-11-13
Abstract: To detect leaks from pipelines carrying fluids, especially oil, light is transmitted through a fibre-optic 3 held in proximity with the pipeline. The fibre-optic is surrounded by a medium 4 e.g. silicone rubber of which the refractive index is altered by the influence of the leaked fluid. Oil soaks into the medium through a permeable cladding (1) and elastomeric protective layer (2), and increases its refractive layer sufficiently to render the fibre optic non-internally-reflective so that light (5) is absorbed. Control means linked to a light receiver detect that change and the position of the leak is located to within the length of the fibre optic. In another embodiment the medium is a liquid which is expelled from around the fibre optic by the action of leaked fluid. <IMAGE>

Patent GB-2079710-A (GB)
Title: Case packer
IPC: B65B21/04
Filed: 1981-04-03
Abstract: The various operations of a case packer are synchronized in accordance with the continuous movement of a flight bar conveyor K. The conveyor K intermittently feeds empty cases to an elevator platform located below the loading area D. The flight bar pushes a case ahead of it along a section 48 of the conveyor which terminates adjacent the end of the platform so as to situate the case on the platform. The bar then travels along a looped "dwell" section 50 of the conveyor, remote from the platform, as the platform is raised for loading and lowered. The bar reaches the end of the dwell section as the platform motion ceases and, thereafter, travels along another section 54 of the conveyor above the platform to remove the loaded case therefrom. A bottle feed conveyor B moves a compliment of bottles into a loading area. The bottles are initially moved rapidly towards stops I at the end of the loading area and, thereafter, the movement thereof is slowed to reduce impact. The dual- speed drive is produced by an air cylinder connected to the conveyor through an overrunning clutch. The stops provided at the end of the loading area engage the tops of the bottles and, additionally, function to sense the presence of a full compliment of bottles in the loading area. <IMAGE>

Title: Method of and apparatus for inserting prepared giblets into dressed slaughtered chickens
IPC: A22C21/00
Filed: 1981-04-22
Abstract: Prepared giblets packaged in bags are inserted into dressed slaughtered chickens, each chicken being guided along a first conveyor track 4 whilst depending from a leg hook 7. Each giblet bag, which is disposed in a dish 12, is brought into the region of the first conveyor track 4 and from there to above the chicken body 8 by a second conveyor track 9, each giblet bag being inserted by a pusher 18 from the dish 12 into the slaughter opening(s) of the chicken bodies which are spread open and disposed above. The apparatus has portions of the first conveyor track 4 for the chicken bodies 8 arranged around the central superstructure and portions of the second conveyor track 9 situated at a lower level than the first conveyor track. The portions are arranged around the superstructure, which is frusto-conical, and means for sliding the pushers 18 against the dishes 12 are disposed on the superstructure. <IMAGE>

Patent GB-2076477-A (GB)
Title: Apparatus generating a reciprocating motion
IPC: F04B43/02
Filed: 1979-11-19
Abstract: The apparatus can be used in several applications, for instance for a pump, an engraving pen. Most apparatuses of this type call for precision-manufactured parts and consequently are expensive to manufacture. Other disadvantages of certain prior art apparatuses of this type is that they are difficult to start. The present invention is based on the insight that the surface of the part (1) performing the stroke motion must be small during the compression stage of the work stroke and large after the compression stage.

Title: D.C. Homopolar machines with superconducting field coils
Inventor: BARTRAM TREVOR CARLISLE
IPC: H02K55/06
Filed: 1981-10-16
Abstract: Rotor 13 carries conductors 14 connected between sets of slip rings 19 and 20 which co-operate with brush sets 21 and 22. Fixed superconducting field coils 15 and 16 are each split into axially-spaced sections 15A, B and C and 16A, B and C to increase the uniformity of the field at the surface of the slip rings and minimize the field component perpendicular to that surface. The number, length and spacing of the field coil sections is chosen to give the required field. Rings of ferromagnetic material may be disposed to further modify the field. At the outer ends of the slip ring sets the slip ring surfaces may be inclined to follow the field lines more closely. <IMAGE>

Title: Discharge lamps
IPC: H01J61/36
Filed: 1981-11-06
Abstract: A vapour discharge electric lamp incorporates a pump stem (5) extending through an aperture in an arc tube envelope (8, 6) and a discrete annular member (10) disposed around and secured to the pump stem (5) to locate the latter in said aperture by abutment against the outside of said envelope. By this means the pump stem (5) which incorporates the cold spot may be accurately located in the arc tube envelope (8, 6), perpendicular to the aperture therein, during assembly and subsequently sealed to the envelope in the desired position. The location of the cold spot enables the colour rendering index of a high pressure sodium vapour lamp, for example, to be controlled. <IMAGE>
