Abstract: 922,309. Pulleys; linkwork. J. W. ANDERSON. Oct. 19, 1960 [Oct. 22, 1959], No. 35815/60. Classes 80 (1) and 80 (3). A cable pulley which may be circular, elliptical, segmental or, as shown, semicircular, comprises a pair of identical flanged mating parts 12, 13, Fig. 2, stamped from sheet metal or the like, the groove formed by the mating flanges having curved side walls 28, Fig. 3, and being lined with a curved rim member 32 having a pair of cable grooves 33, 34. The identical parts 12, 13 are secured together by peening over the hollow lug 25 on one part through the aperture 24 of the other part. The rim member 32 is located by a pair of ears at each end. As applied to the drive between a reciprocating link 40 and an oscillating shaft 22 secured centrally to the pulley, a cable 42 fastened at one end 43 to the link 40 extends into and half-way round one pulley groove 33 and then passes between ears 17, 18 (Fig. 2) to cross into the other groove 34. The emerging cable end 45, which is also attached to the link 40, is thus laterally spaced from the end 43. A lug 48 fastened to the cable fits between the ears 17, 18 on the pulley. The link 40 is curved in cross-section to embrace the curved pulley walls 28. Specification 833,776 is referred to.

Abstract: 396,725. Discharge lamps. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Moore, D. M.; 592, Park Avenue, East Orange, New Jersey, U.S.A.) Dec. 30, 1931. No. 36007. Convention date, Dec. 31, 1930, [Class 39 (i).] In a positive column lamp, a circuit independent of the main discharge is used to ignite an auxiliary discharge between a main electrode provided with a crater and another electrode adjacent thereto to produce a luminous discharge at the crater. A tungsten, magnesium, iron, aluminium or copper cathode 2, Fig. 1, surrounds a copper, tungsten, magnesium or aluminium anode 3 and is spaced therefrom by a layer 4 of mica or alumina. An inwardly projecting flange 5 on the cathode is separated from the anode by a distance less than the length of the Crookes' dark space. The anode is provided with a central crater and the cathode is provided with a number of craters 6 which may be formed in the electrode itself, when the electrode consists of a material of low work function such as magnesium, barium, barium azide, cµsium, thorium, cerium, ferro-cerium or misch metal, or in an insert consisting of one of these materials. The lamp is adapted to be used with alternating-current by the provision of an anode and cathode at each end, as shown in Fig. 1, and the discharge gaps between the two sets of electrodes are connected to the mains in series with a switch 15 and an impedance or a resistance 14. A switch 12 and a resistance 11 are connected in series with the main discharge. The magnitude of the auxiliary discharge current is determined by the resistance 14 and the dimensions of the gaps. The lamp is modified for use with continuous-current by replacing one set of electrodes by a nickel, carbon or tungsten anode provided with a crater. In a further modification, a U-shaped lamp is contained within an envelope 20, Fig. 4, and the resistances 10, 14 and the auxiliary discharge connections are embodied in the lamp structure. In another modification, the cratered cathode 22, Fig. 5, is surrounded bv an anode and is sealed to the glass envelope 23 through a tapered portion 32. A cooling jacket 24 surrounds the electrode chamber and connection to the cathode is effected through a conductor 26a and a spring 27. The anode conductor is led in. through a side arm 29. A plate 31 may cover the end of the cathode crater as described in Specification 377,726. Reference has been directed by the Comptroller to Specifications 307,424, [Class 39 (i), Electric lamps, Arc &c.], 367,271 and 369,824.

Abstract: 768,390. Control of D.C. motors. WOODS OF COLCHESTER, Ltd. Nov. 7, 1955 [Dec. 14, 1954], No. 36216/54. Class 38(3) A pair of contra-rotating axial flow fans are driven by similar compound-wound D.C. motors, maximum speed and power being obtained by connecting the two motors in parallel across a source of supply. For operation at reduced speed and power, the armatures and series field windings are connected in series with one another across the supply, and the shunt field windings are connectable in the different manners, namely, open circuit, series, and parallel, to obtain successively diminishing speed and power outputs. Control of the motors may be effected by means of a multi-position controller which is interlocked with a starter switch so that the starter contacts are opened before the controller is moved from one operative position to another.

Abstract: 1387891 Rotary positive displacement pumps GARDNER-DENVER CO 3 Aug 1972 [5 Nov 1971] 36250/72 Heading FIF A helical screw compressor 10 comprises male and female rotors 12, 14 located in parallel intersecting bores 18, 20, a bearing housing 34 for the rotors providing a low-pressure face 37 with an inlet port 36 and an intermediate housing 30 providing a high-pressure face 32 with an outlet 52, and a capacity control valve including a valve-member 66 axially movable in a bore 64. The valve-member 66 forms a movable wall portion of the working chamber of the compressor and includes a piston 78 integral therewith which has a face 90 which is acted upon by the highpressure of discharged gas in a chamber 54 to open the control valve by forming a vent between the mating surfaces 68, 70 of the housing 16 and valve-member 66. Thus if the hydraulic pressure from the lubrication system to a chamber 81 behind piston 78 fails the valve will be opened by pressure on face 90 so as to minimize the load on the compressor. A guide pin 106 located in mating grooves 108, 110 in the valve-member 66 and housing 16 serves to align the crest 102 of member 66 with the crest 104 of the housing 16 defined by the intersection of bores 18, 20. Lubricating oil is supplied from a manifold 116 to the working chamber via pipe 118, passages 120, 122 in the housing portion 62 defining bore 64, passages 126, 128, 130 in guide pin 106, Fig. 2 and circumferential grooves 112 or (114) in bore 64. Land 136 closes passages (114) in the embodiment shown, liquid thus flowing via passages 112 into the working chamber. Alternatively, a different pin could be inserted and passages 112 closed while passages (114) serve to transmit lubricating fluid Figs. 4 and 5 (not shown).

Abstract: 1,120,518. Pulse generating circuits. INTERNATIONAL BUSINESS MACHINES CORP. 15 Aug., 1966 [1 Sept., 1965], No. 36406/66. Heading H3T. A high voltage pulse generator for an electrostatic printer comprises a single shot multivibrator 40, Fig. 1, which acts through a drive circuit 20 to pass current through one half of the primary winding of a transformer 10 to pre-set the flux in one direction, and a second single shot multivibrator 50 which operates after the first one to reverse the flux in the transformer thereby producing an output pulse in the secondary winding 12 connected to the load 60. A second secondary winding 13 is connected to a diode 14 and energy-dissipating resistance 15 which absorbs the energy of the pre-setting flux and of the collapsing flux after the output pulse. Drive circuit, Fig. 2. A pulse from a single shot multi-vibrator 40 is inverted in unit 21 and used to switch off a normally conducting NPN transistor 22. This causes PNP transistors 23 and 24 to conduct, the latter being in series with the half 11 of the primary winding of transformer 10. At the end of the input pulse the three transistors switch to their opposite states.

The film may be made by slitting a thermoplastic film (suitable materials being listed) with heated knives and simultaneously or subsequently orienting it at elevated temperature by gripping the border sections and moving them apart by means of a tenter. Preferably the film is slit laterally and is stretched in the direction of the slits so that the ribbons formed by slitting are reduced in width and the openings are formed; the openings may have substantially zero width if the film has been folded or corrugated in the direction of stretch. In specific embodiments laterally slit films are oriented to produce films having 50, 74 and oriented ribbons 52, 74. The slit pattern was constituted by staggered rows of slits in Fig. 4, and by parallel near full-width slits in Fig. 6. The film may be extruded, cast or blown and the heat of formation may be utilized for slitting. Specification 1,378,749 describes and claims methods and apparatus for laminating, which may use the above films.
