Title: Improvements relating to street lighting lanterns
IPC: F21V5/04
Filed: 1963-10-23
Abstract: 1,043,849. Lamps for street lighting. LICENTIA PATENT - VERWALTUNGS - G.m.b.H. Oct. 23, 1963 [Oct. 24, 1962], No. 41823/63. Heading F4R. To modify the distribution of the light under wet and dry conditions, a street lighting lantern is constructed with at least part of the outer casing formed of light transmitting material and having double walls 5, 6 forming a cavity 7 in which rain falling on the cover can collect, the outer wall 5 extending beyond the edges of the cover for this purpose. The cover carries reflectors 3 for the lamp 2. A drain hole 13 is provided at the bottom of the cavity. To prevent clogging of the hole, a bimetal strip carrying a plunger is mounted above the hole so that the heat generated when the lamp is switched on causes the plunger to pass through the hole, the plunger repassing in the opposite direction when the lamp is switched off.

Abstract: 958,302. Packaging tumblers. HARTMANN FIBRE Ltd. Feb. 22, 1963 [Nov. 23, 1961], No. 41894/61. Headings B8C and B8P. A packing assembly for tumblers L, L 1 , comprises a plurality of contoured separating leaves A, B of moulded pulp formed on one side with rows of recesses 2 for receiving the bases of the tumblers L 1  and on the other side with corresponding projections for locating the rim of the tumblers L in the layer beneath the material of the recesses being of reduced thickness and having lines of weakness radiating from the centre to allow rupture and penetration of the bases of the tumblers L 1  under impact in packing, thus cushioning the shock of impact of the tumblers and forming cushioning pieces between the base of one tumbler and the mouth of another. The recess 2 may also have an annular base corrugation so that after rupture only the corrugation is in contact with the interior of the tumblers. The interleaved layers of tumblers are normally housed in fibre board boxes but by including a top leaf 8, the leaves need only be overstrapped by wire tape.

Abstract: 1,161,325. Making commutators. ROBERT BOSCH G.m.b.H. 20 Sept., 1966 [23 Sept., 1965], No. 41906/66. Heading B3A. [Also in Division H2] A commutator is made from a copper bar 10 which has a longitudinal notch 11 on its upper side and is stamped on its underside to form segments 13 connected by bridges 14, part of each segment being separated and bent upwards to form connecting lugs 18 either before or after the bar is rolled into an annulus and embedded in an insulating hub 20, Fig. 2 (not shown), and the bridges 14 removed by machining to form separate segments. The bar 10 is advanced intermittently into a stamping machine in which the transverse grooves 12 are stamped by a die after each step. During the stamping anchoring claws 15, 16, 16<SP>1</SP> are formed by cutters and then the segment ends 17 are separated from each other by stamping and bent upwardly. Slots (22) are cut in each lug 18 into which connecting wires are fitted, preferably by dip soldering and clamped by deformation of the lugs. The insulating material is also moulded between adjacent lugs to insulate them.

Abstract: 1,194,329. Electro-chemical analysis. NATIONAL RESEARCH DEVELOPMENT CORP. Dec.20, 1967 [Sept.20, 1966], No.41938/66. Heading G1N. The onset of mastitis in cows is detected by its effect on the electrical conductivity of the milk from an infected teat compared with that from an uninfected teat. In one embodiment, Figs. 1-4 (not shown), the milk from pairs of teats is collected into two single conduits including a conductivity cells, connected in opposite arms of a bridge to operate a relay and audible or visible alarms, to indicate the presence of an infected teat. Alternatively the conductivity of the milk from all four teats, Fig. 5 (not shown), may be sensed individually, the four conductivity cells being connected as the four arms of the bridge. The conductivity cell comprises three electrodes, forming the walls of the conduit through which the milk flows, the outer electrodes being connected together. The conduit is formed as one arm of a V-tube, the milk entering near the top of the other arm so that foam &c. in the milk remains at the top of this arm and does not pass through the conductivity cell.

Title: Improvements in and relating to arrangement for controlling the speed of t avel of punched tape
IPC: G06K7/01
Filed: 1964-10-15
Abstract: 1,062,698. Type-bar-making machines; typewriters &c. O. VIERLING. Oct. 15, 1964 [Oct. 31, 1963], No. 42069/64. Headings B6F and B6W. Controlling by record-strips.-Mechanism for controlling a type-composing machine or typewriter comprises a number of electromagnets connected to a punched tape scanner. An additional scanner is positioned upstream from the first scanner by the distance between code rows in the tape. When the additional scanner, by co-operating with a comparison circuit, senses a code combination to which the machine is not to respond, or which controls only a machine function with limited application (e.g. punched-out errors), the tape feed is accelerated. When the two scanners detect identical signals, the tape feed is slowed down to produce the usual delay necessary in the case of identical characters. In the case of identical signals to which the machine does not respond, the feed is accelerated. the delay mechanism being superseded. With a thrust pawl tape drive controlled by an impulse generator the advance is delayed by suppressing one or more impulses, and accelerated by an additional magnet moving the pawl into a different tooth of the ratchet wheel. Acceleration may be caused by impulses with a frequency corresponding to the resonance frequency of the pawl. With continuous feed, a clutch is arranged to be disconnected for delay and to connect the actuating mechanism to a more rapidly revolving shaft for acceleration. With a drive utilizing a stepping motor with two or more coils normally energized successively or simultaneously to actuate and stop the main shaft, acceleration is caused by signals causing the motor to continue rotating.

Title: Improvements in the treatment of napped acrylonitrile polymer fabrics
IPC: D06M13/228
Filed: 1962-11-19
Abstract: Matting, shedding and pilling of the nap of woven, non-woven and knitted fabrics of fibres made from polymers containing at least 80% by weight of acrylonitrile after subjection to normal laundering and wearing conditions is reduced by treating them with an aqueous solution of a stabilizing agent which consists of butyrolactane and then drying them to evaporate the water from the solution concentrating the stabilizing agent at the intersections of the fibres in the nap and to set forming a durable band between and among them.  The aqueous solution which may also contain water repellents, e.g. "Phobotex" (Registered Trade Mark) and antistatic agents, e.g. polyamine resins such as diethylene triamine cross-linked with polyethylene glycol diiodide or an epoxy resin, may be applied to the fabric by spraying and the fabric may then be dried and cured by heating to 230 DEG -300 DEG F. for 3-30 minutes.  The fibres may be made from polyacrylonitrile, from copolymers containing at least 80% by weight of acrylonitrile copolymerized with another monomer containing <FORM:0979085/D1-D2/1> linkages or from blends of polyacrylonitrile or a copolymer thereof containing 80-99% by weight of acrylonitrile and 1-20% by weight of another copolymerizable monomer with 2-50% by weight of the blend of a copolymer of 10-70% by weight of acrylonitrile and 30-90% by weight of another copolymerizable monomer.  Suitable copolymerizable monomers are acrylic, a  chloroacrylic and methacrylic acids, methyl, ethyl, butyl, methoxy methyl and b  chloroethyl methacrylate, acrylate and a chloroacrylate, vinyl chloride, fluoride and bromide, vinylidene chloride, 1-chloro-1-bromo ethylene, methacrylonitrile, acrylamide, methacrylamide, a  chloroacrylamide, methyl vinyl ketane, vinyl acetate, chloroacetate, propionate and stearate, N-vinyl phthalimide, N-vinyl succinimide, methylene malonic esters, itaconic acid and esters thereof, N-vinyl carbazole, vinyl furane, alkyl vinyl esters, vinyl sulphonic acid, ethylene-a , b -dicarboxylic acids, diethyl citraconate and mesaconate, styrene, vinyl naphthalene, vinyl pyridines and alkyl-substituted vinyl pyridines, 1-vinyl imidazole and alkyl-substituted-1-vinyl imidazoles.  The process is suitable for the treatment of high pile polyacrylonitrile fabrics to prevent matting, pilling and shedding.
