Title: Method of manufacturing and electronic discharge tube including a photocathode
IPC: H01J9/12
Filed: 1969-03-17
Abstract: 1,207,091. Cathode materials and processing. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 17 March, 1969 [15 March, 1968], No. 13772/69. Heading H1D. A method of manufacturing an electronic discharge tube including a photo-cathode, the active constituent of which comprises a strongly p-conductive A III -B V -compound, where A III  is B, Al, Ga or In, and B v  is N, P, As or Sb, which is activated by an alkali or alkaline earth metal, includes the steps of heating the un-activated compound in the tube to a temperature not exceeding 300‹ C. for at least two hours and then, before activation, bombarding a free surface of the compound with rare gas ions having an energy not exceeding 100 eV. Preferably the energy of the rare gas ions is halved for the final part of the treatment. As shown, the photo-cathode 4 of the tube is a monocrystalline. GaAs plate with its surface oriented in the (110) direction and coated with an epitaxially deposited GaAs layer 5, 10 microns thick, which is doped with 3 x 10<SP>19</SP> atoms of zinc/c.c. After degreasing all electrodes in the tube by heating in chlorothene at 60‹ C. for 2 min., the tube is exhausted and heated at 275‹ C. for 4 hours. Pure argon is then admitted at 5 x 10<SP>-4</SP> Torr and a glow discharge ignited between electrodes 7 and 8, and with the cathode held 100 v. negative with respect to electrode 7 an ion current of 30ÁA/sq. cm. is drawn to the cathode surface for 30 min. The voltage is then reduced to 50 volts and ion current drawn for another 15 min. After pumping away the argon, the photo-cathode may be activated by successive additions of caesium, from source 9, and oxygen as described in Specification 1,200,899.
Patent GB-1498550-A (GB)
Title: Fluid pressure operated impact devices
IPC: F16F9/04
Filed: 1976-04-06
Abstract: 1498550 Impact device G A NILSSON K EDSTROM and H WIKLUND 6 April 1976 [7 April 1975] 13782/76 Heading B4C [Also in Division B3] A fluid pressure operated impact device comprises a plunger 4 mounted within a cylinder 1 for movement between a cover 3 and a stop plate 2, a fluid pressure chamber 5, and a sealing element 6 which seals the chamber 5 from the outside when the plunger 4 is at rest with its flange 4a abutting the plate 2, the arrangement being such that upon injection of a pressure fluid into the chamber 5 through a duct 8 the plunger 4 moves towards the cover 3 while the sealing element 6 stretches in the direction of movement (see Fig. 2) until it has broken off its contact with the plate 2 when the fluid escapes through the gaps between the flange 4a and the plate 2 and through the slots 10 provided in the cylinder 1 to the outside when the plunger 4 halts, reverses and assumes its "at rest" position, and the cycle is repeated. The reverse movement may be assisted by a compression spring 13. The impact device may be fitted to a pile or the like. The sealing element 6 may be a rubber ring, plastics cords with round cross-section welded into rings, or a strong rubber hose, and may be glued to the plunger 4 or mounted on a flange plate (19) Figs. 11-12 (not shown) secured to the plunger 4. The seal may alternatively be in the form of bellows one end portion (6c) of which contacts the plunger 4 and the other end portion (6b) contacts the plate 2 whereby upon application of pressurized fluid the plunger 4 moves away from the plate 2. Since the pressure exerted on portions (6c) and (6b) is greater than that exerted on the folds of the bellows the bellows unfold and the portion (6b) Figs. 7-9 (not shown) finally snaps off the plate 2 to allow the fluid to escape. The movement of the plunger 4 may be limited by bolts (15) having a pre-determined free movement in slots (16) on the plunger 4 before engaging the walls of the slots (16) Fig. 4 (not shown). The plunger 4 may be guided by a central shaft (12) wherein another seal (6a) is provided adjacent the shaft (12) Fig. 4 (not shown). The plunger 4 may be guided by three spindles or by four spindles located at its corners. The plunger may have a portion (4c) projecting towards the plate 2 inwardly of the seal 6, Fig. 6 (not shown) thereby reducing the volume of the chamber 5 whereby air pressure rises more quickly in the chamber 5 during the reverse movement of the plunger to act as a cushion. Degree of cushioning can be adjusted by changing the pretension of the spring 13. The plunger surface which accommodates the seal 6 may be made plain and the seal 6 and a support flange may be provided on the plate 2. Alternatively the flanges and the seals may be arranged whereby they face each other.

[Also in Division F2] Apparatus for removing scale from ship's decks comprises a chassis 10 on wheels 11, 13 with handles 16 for manual steering, a shaft 22 carrying abrading elements 30 and rotated by a motor 54 and means 21, 43, 44 for moving the abrading elements into and out of contact with the plating. The shaft 22 is mounted in bearings in a member 21 which is carried at one side of the chassis 10 and overhangs the other side to the full width of the chassis (Fig. 1, not shown). Three shafts 27 which are mounted around the overhanging portion of the shaft 22 serve as pivots for sets of the hammer-elements 30. The motor 54 drives the shaft 22 through belts 38 and 39 which interconnect through a double pulley 37 mounted on a cross-shaft 20. The rear end of the member 21 is pivoted on the cross-shaft 20 and can be turned about it by manipulating the handle 46 operating the linkage 44-43-21 to raise the abrading elements to the inoperative position. The spring 45 serves as a shock absorber and the wheels 11, 13 have resilient tyres.

Filed: 1933-05-12
Abstract: 419,376. Packeting by wrapping. JACKSON, D., and MOLINS MACHINE CO., Ltd., 2, Evelyn Street, Deptford, London. May 12, 1933, No. 13832. [Class 94 (i).] In a machine in which partly formed packets are conveyed by a transfer wheel 2 from a flat position on a bed 1 to a vertical position in a collator 3 along which they are fed intermittently by belts 6, the packets just before reaching the transfer wheel pass under a detecting finger 14 which, when a packet is absent or is without a wrapper, operates to interrupt the drive of the belts 6. The belts 6 pass around knurled rollers 7 which are driven intermittently through gearing 8 by ratchet and pawl mechanism, comprising a pawl 10 eccentrically mounted on a constantly rotating disc 12 and engaging at each revolution a ratchet wheel 13. The packets are removed from the transfer wheel 2 by an ejector 19 which is rocked about its pivot 22 by a rotating cam 28. Should the detecting finger 14 drop, its other end 17 releases a spring- controlled arm 18, which brings a nose 24 into the path of an extension 23 of the ejector 19, which is therefore held in the position shown. A faulty packet thus passes the ejecting position and does not enter the collator. Moreover a link 21 connected to the ejector brings a shield 20 into such a position that the pawl 10 cannot engage the ratchet wheel 13. A bump 32 on a rotating cam 27 co-operates with a roller 26 to restore the arm 18 to its original position.
