Title: Multi-position beam tube
IPC: H01J31/06
Filed: 1954-07-22
Abstract: 769,024 Electron beam apparatus. BURROUGHS CORPORATION. July 22, 1954 [July 24, 1953], No. 21440/54. Class 39(1). A multi-position beam switching tube has an elongated cathode, an inner row of V- or trough-shaped spade control electrodes and a corresponding outer row of anodes or target electrodes which overlie the space between the control electrodes with a portion of each projecting towards a control electrode. The anodes are either V- or L-shaped. As shown in Fig. 1 the cathode 11 is surrounded by spades 12, 12<1>, &c. of V-shape with their orifices towards the cathode and by target electrodes 14, 14<1>, &c. of U-shape, interleaving the spades 12, 121, &c., the electrodes being fixed in mica spacers 13. A coil 15 produces a transverse magnetic field. If one electrode 12<1> is at cathode potential and the others at a higher potential, the electron beam passes to and is locked on electrode 141. Lowering the potential of the adjacent electrode 12<1> switches the beam to target 14<111> where it is locked by the resulting current flow and potential reduction. Each spade electrode is connected through an associated resistor to the supply e.g. 120 volts. Output signals are developed across resistors in the anode circuits. Switching may be attained by reducing the potential of the adjacent spade by commutating means, or by lowering the anode potential or other variations in the characteristics of the beam path. Special beam switching elements of rod-like form may be provided in the angles of the target electrodes, Fig. 3 (not shown). The elements 22 may all be connected together, Fig. 7 (not shown) or connected in sets, Fig. 8 (not shown). In Fig. 4a the anodes 14A<1>, 14A<11> are L-shaped and beam switching elements 22, 22<1> are provided. The beam may be cathode or grid modulated. Specification 759,153 is referred to.

Patent GB-685728-A (GB)
Title: Improvements in the treatment of di-olefinic terpenes
IPC: C07C45/50
Filed: 1950-08-30
Abstract: Di-olefinic terpenes are contacted with a formylation catalyst for sufficient time to give a mono-olefinic terpene.  This is reacted with carbon monoxide and hydrogen using the same catalyst to give a saturated terpene aldehyde and, on hydrogenation, a terpene alcohol. The first treatment is effected at a temperature of 0-300, preferably 140-190 DEG  C. for about 1 hour with a Group 8 metal catalyst, preferably cobalt-thoria-silica.  Cooling yields camphene which, on addition of hydrogen chloride, gives pinene hydrochloride.  By cooling to 130-140 DEG  C. and reacting with water gas, terpene aldehydes are formed which may be hydrogenated simultaneously or subsequently with the same or other catalysts, e.g. nickel or copper oxide-chromic oxide.  Diolefinic terpenes C10H16 yield alcohols C11H20O used for the preparation of foaming and wetting agents, softening materials, cosmetics, and perfurmes.  In examples: (1) a terpene fraction from turpentine is dropped slowly on to a cobalt catalyst in a distillation column, the product distilling off under the heat produced.  Molecular weight is unchanged; (2) a terpene fraction is autoclaved at 170 DEG  C. with the same catalyst for 1 hour; (3) a terpene fraction is autoclaved as in (2) with a reduced cobalt catalyst, cooled to 135 DEG  C., and water gas introduced at about 150 kg/cm2 to produce aldehydes which are hydrogenated in the same vessel.

Abstract: 617,160. Valve gear for hydraulic apparatus. DENISON ENGINEERING CO. Aug. 22, 1945, No. 21503. Convention date, July 19, 1944. [Class 69 (ii)] A control valve for controlling the supply and exhaust of pressure liquid to a power unit for actuating a press &c. is controlled by the rate of exhaust from the power unit to control the supply of pressure liquid to the unit to limit the maximum speed of the unit. The valve comprises a ported barrel 40 mounted in a housing having ports 31, 32 connected to the lower and upper ends of a cylinder containing the power piston, port 30 connected to the pressure liquid supply and ports 33, 34 connected to exhaust. In'the position shown in Fig. 2 liquid is supplied to the lower end of the power cylinder and liquid is exhausted from the upper end to raise the piston until a lever moved by the piston engages a collar to raise the barrel 40 against the pressure of the spring 47a to close the port 31 and reduce the connection between the port 32 and port 34 and partly open the port 32 to the inlet port 30, whereby the power piston is maintained in its upper position. The barrel 40 is raised further by a hand lever to initiate the downward stroke of the power piston by fully opening the connection between the inlet port 30 and the port 32. At the same time, the port 31 is opened to the exhaust port 33 through the throttle passages 51 in the barrel 40. The pressure in the port 31 is proportional to the speed of descent of the power piston and through ports 53 acts on a shuttle valve 57, mounted within the barrel 40, and when the pressure rises to overcome the spring 63, the valve 57 is raised and the head 60 uncovers ports 55 to connect the port 30 through the ports 54 and 55 to exhaust to reduce the supply of pressure liquid to the upper end of the power cylinder and reduce the speed of the power piston. When the power piston reaches the limit of its downward stroke, the pressure beneath the valve 57 falls and the valve 57 is returned by the spring 63. If the hand lever is released, the barrel 40 is returned to the position shown in Fig. 2, by the spring 47a and the power piston is raised. In a modification the throttle ports 51 are replaced by an adjustable throttle needle valve.

Abstract: 860,803. Cutting tubular thermoplastic stock. LUETZOW, A. E. July 8, 1957, No. 21583/57. Class 87(2). [Also in Group XVII] Tubular thermoplastic stock is gripped under tension in a flattened condition and a hot wire is brought into melting contact first with one layer and then with the other layer of the tensioned stock to successively separate the layers from the remainder of the stock while leaving this remainder unsealed. In apparatus for forming a bag for covering garments using this method, a garment is mounted on a hanger beneath a roll of the tubular thermoplastic stock, a length of which is pulled down over the garment and separated from the roll by a cutting device. This device includes a stationary part, Figs. 6, 14, which comprises a metal base member 38, a pair of spaced metal channels 39 having their outer sides 40 of less length than their inner sides, and a pair of yieldable rubber pads 41 mounted in the channels. It also comprises metal base members 42, each having a metal channel 43 forming a mounting for a yieldable rubber pad 44 with a top face 45 of glass or other suitable heat insulating material and a heat insulating coating or tape 45a. Referring to Figs. 7 and 14, the movable part of the device, which is pivoted so as to enable it to be swung by means of a compressed air-operated device towards the stationary part, has base members 46 and 47, the forming having a metal channel member 48 in which is mounted a heated cutting wire 49. When the edges of channel 48 engage the double thickness of the stock and force it towards the stationary part, the stock is drawn over the edges of the inner sides of channels 39 and at the same time pressed into the pads 41 so as to be tensioned as it bridges these channels. The wire 49 is so positioned as not to engage the stock until this has been tensioned. The base members 47 which are arranged to coincide with the base members 42, have metal channels 54 in which are mounted rubber pads 55 with top glass faces 55a. A heated cutting wire 56 extends lengthwise of the outer surface of each glass face 55a, and each wire 56 has a neck extension 67, Fig. 7. The wires 56 and extensions 67 engage and cut through the plies of stock and melt their edge portions together. After removal from the apparatus ,a cord or ribbon may be tied about the neck portion of the bag and the projecting hanger hook.
