Title: Device for gapping lengths of sliding clasp fastener stringer forming material
IPC: A44B19/58
Filed: 1966-02-01
Abstract: 1,132,247. Making sliding clasp fasteners. M. PERLMAN. 1 Feb., 1966 [2 Dec., 1965], No. 4339/66. Heading E2S. A device for gapping interlocked lengths of sliding clasp fastener stringer forming material, each consisting of a tape to which is sewn a coil made from a single filament, each coil turn constituting a fastener element, comprises a lower die block 12 which is bifurcated to provide a slot therethrough, an upper, vertically displaceable block 16, which is bifurcated to provide a slot therethrough which is aligned with the slot of the lower block, said blocks cooperating to hold the interlocked lengths of said material in place while the lower block guides a pair of interlocked lengths of said material, a vertically displaceable plate 20 positioned above the upper block and normally held in spaced parallel relationship with this upper block by helical springs 24, 24a, a rod 26 rigidly secured to the plate, the plate being displaceable vertically by appropriate means against the bias of the springs by force applied to the rod, thereby displacing in an up and down direction the upper bifurcated block, a punch 14 rigidly secured to said plate, said punch being always disposed in the slot of the upper block, but movable relative to the slot into the slot in the lower block, said punch formed with an arcuate end, the thickness of the punch being such that the space between each of its side faces and the faces of the slot of the bifurcated lower block is narrower than the thickness of the filament from which the coils are made, the faces of the lower block terminating as sharp cutting edge portions, and like the punch, made of hard steel or any abrasion-resistant material. The movement of the plate downwardly first causes the block 16 to move downwardly to clamp the interlocked lengths of material and subsequently causes the punch 14 to move relative to the block 16 to cut the coil sections. The punch instead of having flat sides can have sides formed with notches which dig into the cut turns and pull them downwardly.

Title: Television camera apparatus
IPC: H04N5/228
Filed: 1964-02-04
Abstract: 1,011,454. Television; cathode-ray tube circuits. M. GRUNDIG. Feb. 4, 1964 [Feb. 23, 1963], No. 4650/64. Headings H4F and H4T. In a television camera the electron beam which scans the storage layer of the pick-up tube, e.g. a vidicon, is controlled so that the duration of flow of charging current from the beam to a scanned elemental image point of the layer is less than the time allotted to the scanning of that point, e.g. less than 20%, the electron beam being pulsed so that more than one pulse occurs during said time allotted. Keying pulses a, Fig. 2, for the beam current are applied to the cathode 1, Fig. 1, of the camera tube 2 through amplifier 3 which converts them into negative pulses b. In this embodiment the duration of the flow of current is 10% per image point and thus as the signal current i is determined by the equation i = #Q/#T (in which #Q is the charge to be supplemented by the scanning electron beam and #T is the time for the supplementing of the charge per image point), the signal current i increases by the factor 10 on a reduction in the time #T to 10%. The output signal c, modulated by the picture content, appearing at the signal plate 4 is supplied to an amplifier stage 5 which converts signal c into a sine wave train d the period of oscillation of which is twice the keying pulse duration. After amplification the sine wave train d reaches a holding circuit which extends the amplitudes of oscillation to produce signal e which contains all the original signal frequencies. The gaps f may be eliminated by a low-pass filter. An alternating-current amplifier may be used instead of a direct-current amplifier.

IPC: E02F3/43
Filed: 1972-02-02
Abstract: 1382068 Shovelling machines INTERNATIONAL HARVESTER CO 2 Feb 1972 [4 Feb 1971] 4815/72 Heading E1F [Also in Division B8] Electro-hydraulic means for a vehicle having an earth-working or load-handling implementcarrying boom comprises a control circuit for actuating the hydraulically-actuated boom and the hydraulically-actuated implement whereby actuation of the boom and the implement may be initiated to a programmed cycle of movements solely by the closing of an electrical switch thereby enabling the operator of the vehicle to retain both hands on the steering wheel of the vehicle except for the short period of time when the switch is actuated. The control circuit comprises a first electrical circuit for automatically raising the boom, a second electrical circuit for automatically and continuously oreintating the implement in a predetermined relationship with the boom, a third electrical circuit for automatically rotating the implement from a first to a second position. The third circuit includes means for maintaining the implement in the second position for a pre-selected period of time before automatically returning the implement to the first position. A fourth circuit controls lowering of the boom. Fifth and sixth circuits control automatically the orientation of the implement with the ground when the implement is adjacent the ground. Each of these circuits is rendered effective in a predetermined sequence by merely closing the switch. The circuits involve variable impedances controlled by the boom and the implement to create compared signals from which a control signal is obtained for the regulation of the valve control means of the hydraulic circuits of the actuators of the boom and the implement. Specifications 1185568, 1340399 and U.S.A. Specification 2876921 are referred to.

Title: Improvements in carburetters for internal combustion engines
IPC: F02M69/00
Filed: 1936-02-18
Abstract: 470,646. Spray carburetters. SOC. GENERALE DES CARBURATEURS ZENITH. Feb. 18, 1936, No. 4960. Convention date, Feb. 19, 1935. [Class 7 (iii)] In a carburetter having a fuel-pressure regulator comprising a diaphragm controlling a fuel inlet valve to the fuel chamber of the regulator, which is floatless, a chamber, separated from the fuel chamber by the diaphragm or having a movable wall operatively connected thereto, is connected by a suction passage to the induction pipe behind the carburetter throttle valve and by an air passage to the air intake or atmosphere and a valve controls one of these passages to increase the suction passage or decrease the air passage in such a ratio that the fuel supply falls below the minimum required to form a combustible mixture. The dry side 14 of a diaphragm 12 is connected by a passage 16, having a calibrated orifice 17, to the atmosphere or air inlet of the carburetter and by a passage 15 with the mixing chamber 1 behind the throttle valve 2, a valve 18 in this passage being adapted to be opened to communicate the depression of the mixing chamber 1 to the chamber 14 and thereby displace the diaphragm 12 to close a fuel inlet valve 11 and stop the engine. Alternatively, the valve 18 may be in the air passage 16 and be closed to stop the engine. In another form, the passages 15, 16 connect with the chamber 14 through a common passage and a two-way valve puts the air channel in communication therewith for normal use or the suction passage when it is desired to stop the engine. As applied to the carburetter described in Specification 464,327, and comprising a manually controlled needle 32, Fig. 5, for varying the amount of suction communicated by a passage 29 from the mixing chamber 1 behind the throttle to the chamber 14 to adjust the strength of the mixture for different altitudes, the chamber 14 communicates through a valve 23 and passage 22 with the air inlet 3 and through a calibrated orifice 36, byepassing the needle valve 32, with the mixing chamber. The orifice 36 and the valve 23 may be interchanged. As shown, the diaphragm 12 is influenced by a spring 13 and the pressure of this may be completely neutralized by associating the diaphragm with a larger diaphragm forming one wall of a chamber corresponding to the chamber 14. In all the above forms, the throttle valve 2 operates a needle valve 5 controlling a spraying orifice 4 arranged above the throttle valve 2. As shown in Fig. 7, the fuel nozzle 41 is below the throttle valve 43 and the chamber 14 is open to the atmosphere through a calibrated orifice 49 and communicates with the induction pipe behind the throttle valve by a valved passage 50. Fuel for idling is supplied through a well 44 and passage 46 having a calibrated air inlet 48. Specification 474,975 also is referred to.

Title: Ionomer coverings for articles
IPC: B29C61/10
Filed: 1972-02-03
Abstract: 1342202 Coating with preformed sheets AMP Inc 3 Feb 1972 [12 Feb 1971] 5059/72 Heading B6G [Also in Divisions C3 and F2] Articles are provided with tightly-fitting coverings (e.g. sheaths or linings) of a photolytically cross-linked ionomer, the coverings having a fusion-welded seam, by forming a loosely fitting covering to the article with one or more pieces of the ionomer in a heat-sensitive dimensionally unstable state, with a seam or seams between the edges of the piece or pieces, and heating the piece(s) of ionomer to fusionweld the seam or seams and return the ionomer to a dimensionally stable state as the tightlyfitting covering. The welded seam may extend axially or helically around the article. The ionomer is a copolymer of a C 2 -C 8  alpha olefin, e.g. ethylene, with an alpha, beta-ethylenically unsaturated monocarboxylic acid, e.g. acrylic, methacrylic or ethacrylic acid, at least 50% of the acid groups being neutralized in metal salt form. The ionomer is converted to the dimensionally unstable state by irradiating with ultraviolet light, shaping (e.g. into a sheet or ribbon), heating and subjecting the shaped ionomer to dimensional change while hot, and then cooling in the dimensionally changed state. (The product has a heat-responsive dimensional memory and will tend to return to its original dimensions when reheated; thus for sheaths a heat-shrinkable product is used and for internal linings a heat-expandable product.) The ionomers may include a filler, e.g. carbon black. Protective coverings can be applied to pipes, pipe-lines, telephone and telegraph cables, high-pressure couplings, high voltage cables and to thermal insulators such as fibreglass, glass foam, polyurethane foam, calcium and magnesium silicates and asbestos.
