Title: Improvements in circular knitting machine for hosiery (stockings) operating with bearded needles
IPC: D04B9/46
Filed: 1959-06-12
Abstract: 909,036. Knitting - machines. SESSA-MORETTA, M. June 12, 1959 [June 14, 1958]. No. 20137/59. Class 74 (2). For each needle of a bearded needle circular machine, there are a separate presser and sinker, both accommodated in a respective common trick in a rim surrounding the needle cylinder. The pressers 13 and sinkers 20 have each one flat face, the beard pressing part 15 and a butt-bearing part 17 of each presser standing proud, as thickenings, from the other face, whilst the other face of each sinker is relieved to provide a thin front part 21; and a presser and a sinker are arranged in each trick in the sinker head, with their flat faces apposed, so that the operative ends of pressers and sinkers are respectively opposite the needle beards and between the needles. The pressers are selected, to press or not to press, by a pin drum 29 or 29<SP>1</SP> acting through blades 25 or 25<SP>1</SP>. In Fig. 7, blade 25<SP>1</SP>, when moving from the rest position (chain line) to the presser actuating position (full line) can pivot about a pin 50 until a second pin 53 bottoms in a notch in the slider. Thus, the operative end of the blade can follow the presser, as the cylinder revolves, and ensure that it shall remain pressed for the necessary minimum period, whilst still remaining sufficiently thin to enable neighbouring pressers to have butts at the same height. The whole slider assembly may be moved to inoperative position by projections 41 on the central control drum 40 and all pressers can then be operated, through their butts 19, by a cam 46. The stitch cams 23, 23a have each a step 24, 24a, which temporarily arrests the descent of the needles, and, at the time of this dwell, the sinkers (which are at other timed advanced) are retracted. Thus, in heel formation, the yarn tensioned between the thread guide and the last of the idled needles 5a, Fig. 11, rides on the top border of the sinker adjacent to that needle, so that, at the point X at which the presser of the first active needle acts, the yarn is safely within the hook of the needle and will not be pinched by the beard tip.

Title: Improvements in or relating to joints in electric cables
Inventor: HEWETT NORMAN BASIL
IPC: H02G15/18
Filed: 1954-07-09
Abstract: 765,705. Game-joints. SIEMENS BROS. & CO., Ltd. July 8, 1955 [July 9, 1954], No. 20188/54. Class 38(1). In jointing a pair of multi-core cables having thermoplastic insulation, tubes of thermoplastic material, e.g. polyvinyl chloride, which have been expanded when heated and cooled in the expanded state, are slid over the jointed conductors so as to overlap the insulation thereof and are heated to cause them to contract down on to the said insulation. After binding the joints a large, expanded, thermoplastic tube is passed over them so as to overlap the cable sheaths and is similarly contracted down on to said sheaths by heating. The armouring wires are then replaced and if outer sheaths are provided, a further expanded tube is slid over the joint and contracted to unite them. The overlapping parts of the tubes and cable insulation may be sealed by moulding rings of polyvinyl chloride over them or coating the inner surface of the tube ends and/or the outer surface of the cable insulation with a solvent or cement to cause the parts to unite after the tube has been contracted. Alternatively a tape of plastic material having an adhesive on one or both surfaces may be applied over the overlapping parts.

Title: Improvements relating to light units for use in light signals or indicators
IPC: F21V8/00
Filed: 1948-08-04
Abstract: 649,063. Railway signals. WESTING - HOUSE BRAKE & SIGNAL CO., Ltd., PETER, L. H., SHEPPARD, E. A., and STEVENS, S. A. Aug. 4, 1948, No. 20586. [Class 105] [Also in Groups XI and XXXVIII] A light unit for light signals or indicators comprises two or more sources of light and a single light guide conveying light from the sources by internal reflection and emitting it at the end thereof. The single light guide comprises a rod 1 of transparent material and three tributary rods 5 of similar material formed integral or held detachably in abutting contact with the rod 1. Each of the tributary rods 5 is connected to a lamp housing 6 in each of which a filter 8 colours the light before it enters the associated rod 5 ; reflectors may be employed in the lamp housing to concentrate the light on to the ends of the rods 5. The lamps are controlled in accordance with traffic conditions to supply light of correct colour to the light guide, which light is emitted by the end 3 of the rod 1 remote from the tributary rods 5. This end 3 is positioned at the focus of a concave reflector 9 which directs the diverging rays from the rod into a parallel beam. The end 3 may be shaped as a truncated cone as shown or in the form of a bead ; or it may have facetted surfaces. In another embodiment, Fig. 2 (not shown), the rod 1 passes through a central aperture in the beam forming reflector and the rod end is made bulbous with its tip formed concave and made reflecting to present to the guided light a convex reflecting surface with focus at the focus of the reflector. Instead of using a reflector to form a beam, the light emitted by the rod may be concentrated by a lens system, in which case the rod end is located at the focus of the system ; or alternatively the rod end may itself constitute a lens by being flared in conical manner and having its end surface of lens contour. Fig. 4 shows the invention applied as a indicator signal on a control panel 15. The rod 1 extends through an aperture in the panel and has a domed end positioned to coincide with the appropriate part of a light signal engraved on the panel front. Part of the surface of the light conducting rod may be silvered to prevent loss of light. According to the Provisional Specification two of the filters 8 may be of the same colour, e.g. so that one may act as a standby.
