Title: Knitting machine
IPC: D04B23/00
Filed: 1947-04-29
Abstract: 638,421. Knitting. DEHN, S. G. (Vanity Fair Mills, Inc.). April 29, 1947, No. 11461. [Class 74 (ii)] In a tricot - type knitting - machine having stationary sinkers, movable thread guides located thereabove and sinker nibs, the hook knitting-needles and co-operating tongues are moved longitudinally by eccentric-operated means and, at the same time, bodily laterally, all in timed relation to effect knitting operations. The needle-bar 44 and torque bars 43 (and thus the needles N and tongues T) are given individual figure-eight movements, Fig. 4, by shafts 33, 39, reciprocated by eccentrics on a shaft 18, through bores in blocks 25 themselves reciprocated laterally, at twice the frequency of reciprocation of shafts 33, 39, by eccentrics 29 on a shaft 19. Each needle moves through a curve N, C, carrying the tongue with it, and, at the same time, the tongue reciprocates in its groove, in a straight line represented by TM. The nibs 49, 51 may be replaced by movable nibs 100, Fig. 23 (not shown), reciprocated by eccentrics on a shaft 110, driven at the same speed as shaft 18. Thread guides 63, 63x may be reciprocated vertically, along lines represented by T'G, T<SP>2</SP>G, from a shaft 20 rotating at .the same speed as shaft 18; or, Fig. 29, may be moved in a circular path, at the same frequency as that of the needle and needletongue reciprocation, by eccentrics 115c, eccentric blocks 114c and a cross-rod 113c on which the guides 63c and 63xc are mounted. By means of another eccentric 119 on shaft 19c (corresponding to shaft 19), linkwork 120-124 and adjustable pivot points 122, 125, 126, the paths of movement of needles and tongues may be modified. The thread guides may be racked by pattern wheels acting in opposition to springs and driven from the main eccentric shaft.

Title: Improvements in or relating to electrical contact elements
Inventor: MAER PETER STUART
IPC: H01H1/021
Filed: 1954-04-23
Abstract: 800,551. Impregnated electric contact brushes. NOBRAC CARBON, Ltd. June 6, 1955 No. 11777/54. Class 140. An electrical contact element of carbon or graphite or mixtures of carbon and/or graphitewith a metal or metals includes a proportion of between 10 and 50 per cent by weight of polymerized tetrafluoroethylene or mono-halogen substituted derivatives of tetrafluoroethylene and the requisite porosity is provided by incorporating into the moulding mixture, before moulding, a substance which either vaporizes or sublimes within the mixture to provide the required porosity or alternatively is a substance or substances which, during curing, is unaffected itself and is subsequently removed after curing by leaching or the like, and the mixture thus prepared is first impregnated with a dispersion or suspension of the polymer and subsequently impregnated with an aqueous solution of silver nitrate which is then reduced to metallic silver. Impregation of the porous brush element with the polymer may be effected by vacuum and pressure means using a suspension of particles of the polymer in water or a suspension of polymerized monochlorotrifluoroethylene dispersed in butyl-glycollate. The impregnated brush element is then heated to sinter the impregnant. Examples describe the following means of rendering the brush mixture suitably porous: (i) graphite, ammonium chloride and phenol-formaldehyde resin powder are mixed, moulded under pressure and then baked in a non-oxidizing atmosphere whereby the ammonium chloride is removed by subblimation and the resinous binder is carbonized; (ii) petroleum coke, pitch and sodium chloride are mixed in a heated mixer, moulded under pressure and baked in a non-oxidizing atmosphere after which the sodium chloride is removed by forcing water through the structure or by leaching and the resultant body is then heated in an electrographitizing furnace. After impregnation with the polymer the brush may be impregnated with silver nitrate solution, followed by reduction, one or more times. Suitable reducing agents are gaseous hydrogen or formaldehyde. In an example a block of porous electrographite, previously impregnated with the polymer, is boiled in an aqueous solution of silver nitrate, dried in a current of warm air, then heated in a current of hydrogen in a sealed container and finally raised to an elevated temperature to complete the reduction. The block is then used for making contact brushes.

Title: Image display device
IPC: G02F1/135
Filed: 1970-03-12
Abstract: 1,253,325. Modulating light. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 12 March, 1970 [15 March, 1969], No. 11913/70. Heading H4F. [Also in Division H1] In an image intensifier of the type comprising a photo-conductive layer and an electric field sensitive layer sandwiched between electrodes connected to a source of potential difference so that an image incident on the photoconductor sets up a charge pattern and thereby causes the field sensitive layer to locally modulate a projection light beam incident thereon, it is sometimes possible for the projection beam to reach the photoconductor and so reduce the contrast of the intensified image. This may be prevented by disposing a layer of semi-conductor material between the photo-conductor and field sensitive layer, such material having a direct band gap less than that of the photo-conductor, by an amount preferably not more than 0À2 eV so that it strongly absorbs radiaton corresponding to the direct band transition of the photo-conductor. Thus if the photo-conductor is copper activated CdSe (1À8 eV gap) the semi-conductor may be CdTe, GeS or Sb 2 Se 3  (1À5, 1À7 and 1À4 eV respectively) vapour deposited at room temperature to provide a fine crystalline layer with a resistivity at least equal to the dark resistivity of the photo-conductor, i.e. 10<SP>-7</SP> ohm cm. in this case. A mixture of 3 parts Sb 2 Se 3  to one of GeS is preferred. In a Schlieren optical system, Figs. 1 and 2 (not shown), the field sensitive layer (14) is deformable, e.g. of polymerized silicone oil. In Fig. 3 (not shown) the sensitive layer (36) is a nematic liquid crystal which varies in transmissivity or reflectivity according to the local electric field. A Schlieren system may again be used employing the reflectivity variation, or the variably transmitted projection beam may de reflected from a mosaic of cracked aluminium foil (35) between the liquid crystal and semi-conductor (34) layers to give direct reproduction on a screen.
