Title: Cold-cathode glow-discharge tubes
Inventor: HALL RAYMOND FREDERICK
IPC: H01J17/06
Filed: 1962-02-14
Abstract: 937,391. Cathode materials and processing. MULLARD Ltd. Feb. 14, 1962, No. 5666/62. Class 39 (1). The cathode of a glow-discharge tube has a surface layer containing gold, CsAu and an oxide of caesium. The cathode may comprise a cylinder 5 of molybdenum or nickel, or a glass support coated with molybdenum or tin oxide, or a gold strip. As shown, a gold wire filament 9 is wound on a platinum-coated molybdenum wire 7 which may constitute the anode. Alternatively, the anode may comprise a rod 10 alone, or a ring 17 supported on rod 10. During manufacture, the tube is heated to 350 C. and exhausted through stem 4. The electrodes are outgassed by passing a current through filament 7 and inductively heating cathode 5. A further tube, containing a compressed powder mixture of 2 parts silicon to 1 part of caesium dichromate, or 1 part silicon to 1 part of caesium chromate, is joined to stem 3, and the mixture is heated to cause caesium to be deposited on the walls of this tube. The gold 9 is then evaporated in vacuo or in neon at low pressure and deposited on the cathode 5. After exhaustion, caesium is distilled from the further tube so as to react with the gold cathode layer, by heating at 100  C. until photo-emission from the cathode reaches a maximum, e.g. about 1¢ hours. After sealing off stem 3, and admitting neon at 10 mm. of Hg, a discharge current of 10 mA. is passed between cathode 5 and anode 17 and pure oxygen is slowly admitted until the maintaining voltage of the discharge is a minimum, e.g. 31 to 33 v., or until thermionic emission from the cathode at 100 C. in the absence of neon is a maximum. Finally the tube is again exhausted and refilled with neon at 5 to 20 e.g. 10, mm. of Hg, or with helium at 3 to 20 mm. of Hg.

Title: Improvements in and relating to apparatus for measuring the phase and amplitude of mechanical vibrations
IPC: G01H1/00
Filed: 1942-04-29
Abstract: 555,595. Mechanical vibration measuring. BRITISH THOMSON-HOUSTON CO., Ltd., and HOPKIRK, K. R. April 29, 1942, No. 5777. [Class 106 (iv)] A pair of relatively movable contacts 3, 6 are connected in the circuit of an electrically operated stroboscopic lamp, the contact 3 being carried by a micrometer screw 1 so that it can be adjusted to or away from the contact 6, the vibratory movement to be measured being transmitted to one of the contacts. The graduated head 2 of the screw is read against a pointer 5 fixed to the support 4. The contact 6 is carried by a flexible member 7 attached to a support 8. Connections 10 connect to the lamp circuit. A stop 9 limits movement of contact 6 towards contact 3. Alternatively a contact pressed by a spiral spring is carried on the screw 3 or on a rigid part carried by the support 8. The device is assembled with the supports 4 and 8 electrically insulated from each other, the vibration being in the line between the contacts. It is immaterial which contact is vibrating. The screw 3 is moved so that the contacts just touch at the maximum amplitude of the vibration in one direction. Contact 3 is moved further towards 6 until the stroboscopic indications suddenly cease. The difference in the readings is a measure of the amplitude. In the case where the vibration is due to an unbalanced rotating shaft, the instantaneous position of a mark on the shaft can be observed and recorded. The position of the contact 3 is recorded at this stage to give the phase of the vibration.

Title: Improvements in or relating to paper ruling and like machines
IPC: B41G3/00
Filed: 1926-03-02
Abstract: 268,934. Shaw, A. V., and Shaw, W. E. March 2, 1026. Delivery apparatus.-Sheets are delivered from a paper ruling, printing, perforating, &c. machine by tapes 3, 4 on to a board 15 which is automatically lowered by ropes 16 passing, around vertical drums as 162 which are operated by mechanism controlled by the height of the pile. The drums 16<2> are geared by worm gearing to a shaft 20, and, as the sheets are delivered on to the pile, the shaft 20 is operated at the desired intervals by a ratchet 21 and a pawl 22 mounted on a rocking arm 23 fitted with a catch 30 coacting with a trip lever 31 controlled by a runner 37 resting on the pile and mounted in ball bearings in an arm 36 on a shaft 35 fitted with an arm 34 coacting with a lever 33 connected by a link 32 to the trip lever. If the board 15 is sufficiently low to receive the sheets, the trip lever 31 engages the catch 30 and the arm 28 is prevented from being returned by a spring 28 In this position an eccentric pin 25, which engages a slot 24<1> in a link 24, causes the.link to oscillate on its pivot without operating the arm 23. When the pile rises, the trip lever 31 is raised out of the path of the catch 30, and the arm 23 is moved by spring 28 so as to cause the pawl 22 to slide backwards over two or three teeth of the ratchet 21 which is subsequently advanced as the arm 23 is moved away from the stop 29 by the link 24 and eccentric 25. The board is thus lowered and the arm 23 again held by the trip lever 31. Tne shaft 20 can be operated by a hand-wheel 42 to raise or lower the board manually. The bearers 15<1> of the board 15 may be provided with wheels to wheel the pile away.

Abstract: 1,004,016. Valves. ELECTROLUX A.B. Feb. 12, 1964 [Feb. 25, 1963], No. 5838/64. Heading F2V. [Also in Division A4] A control valve for use in an automatic dish-washing machine (see Division A4) comprises a housing 91 with a chamber 92, an inlet 93 and an outlet 94. The valve is maintained shut by a valve disc 96, mounted on a spindle 95, held against the outlet by compression coil spring 97. In operation the sequence of the water supply is controlled by electromagnetic valves 42, 47 (Fig. 1, not shown). Water from pipe 60 fills the chamber 92 helping to keep the valve shut, water from line 62 pressed against diaphragm 100 to depress valve spindle 95 downwardly. The force due to the spring 97 and the water pressure from line 60 prevents this. The water supply from pipe 60 is then shut off, and after the water in chamber 92 has leaked past shoulder 98, the pressure in line 62 opens the valve against spring 97 moving valve disc 96 to the bottom of chamber 92. Water is again supplied through line 60 to pass to outlet 94 via inlet 93 and chamber 92, the pressure being sufficient to keep the valve open even when the supply to line 62 has been shut off. The valve returns to its original shut position, after the supply from line 60 has been turned off, due to the action of spring 97.

Abstract: 988,382. Stacking sheets. SPERRY RAND CORPORATION. Feb. 15, 1962 [April 10, 1961], No. 5926/62. Heading B6H. Documents 20 are stacked in a bin formed by members 43 to 45 by a pair of slotted discs 10, 11 to which the documents are successively fed by a belt conveyer system 21, 22. Guides 30, 31 ensure that the leading edge of a document engages in the arcuate slots in the discs. The discs are rotated continuously at a peripheral speed which is less than the speed at which the documents are advanced by the belt conveyer system so that when a document is thrust into a pair of arcuate slots its leading edge engages the outer arcuate faces thereof and receives a frictional braking therefrom. The discs rotate in an anticlockwise direction, as shown, and documents engaged in the arcuate slots are stripped therefrom by fingers 41, 42 formed at the ends of the members 43, 44. The documents are then stacked vertically on the members 43, 44, the stack being supported by members 47a, 47b which are spring-urged towards the discs. The members 43, 44 are inclined to the horizontal as shown at A and B so that one edge of the documents rests upon the member 45. The lower conveyer belt 22 passes round a pulley 25 so that the documents 20 are fed to the discs 10, 11 in a direction which is almost tangent to the peripheries thereof. The guides 30, 31 may be replaced by a series of small rotating brushes. A number of stacking devices, e.g. three, may be arranged side by side, the pairs of rotating discs being mounted on a common shaft.

Filed: 1945-03-20
Abstract: 579,941. Electroplating. VANDERVELL, G. A. March 20, 1945, No. 6024/44. [Class 41] An electrolytic bath is fitted with auxiliary electrodes in addition to the anode and cathode, in order to control the distribution of the plating on the cathode, the auxiliary electrodes being maintained at a potential different from that of the cathode. As applied to the plating of the internal surface of bearing shells, the apparatus consists of sides 1, base 2, and ends 4, which are fastened together by screws 23. The bath has two contact rails 3 upon which the bearing. shell S rests. These rails are connected at their ends by supports 8 and have vertical terminal rods 10 fixed into their ends. Rods 10 pass through an insulating carrier 6, strengthened by frame 5, carrying the anode 24, which at its centre has a connection passing through carrier 6 to the socket 20. On either side of the anode 24, longitudinal strips of rubber 26 are let into the face of carrier 6, making contact with the edges of shell S. Guard rails 7, 7 acting as the auxiliary electrodes, are fixed to supports 14, which are bent over at their ends to rest on top of the end plates 4, and may be adjusted to the work by placing packing 16 between the ends of sup-, ports 14 and the plates 4. A wire 22 is placed in a central groove running along the base 2 and is connected through support 15 to rods 14. After the plating is completed, carrier 6 may be removed by handles 17 and placed on a tilted draining board, on which the rails 3 and the bearing can likewise be placed, Fig. 5 (not shown). The negative of the source is divided into two paths, Fig. 6, one supplying the rails 3 and the other the electrodes 7, 22. Resistance R1 is adjusted to give the correct voltage between anode and cathode for the plating process and R2 is adjusted to give the correct potential to such of the auxiliary electrodes as may be required. Where a superposed A.C. or pulsating D.C. are employed in the main circuit it is possible to use similar potentials between the cathode and auxiliary electrode. Specifications 419,764 and 573,635 are referred to.

Title: Improvement in process for flame spraying plastisol
IPC: B05B7/20
Filed: 1953-03-06
Abstract: <PICT:0744377/III/1> A plastisol, liquid at room temperature, comprising a finely-divided vinyl resin dispersed in a liquid plasticizer is flame-sprayed on to a surface by atomizing it to form a spray of particles which are passed through a flame to cause partial solvation of the resin in the plasticizer and to produce a partially gelled dispersion, which is deposited on the surface and to which heat is applied to complete the solvation and fuse the particles into a continuous film.  Several such layers may be deposited and integrally bonded to one another.  As shown, an oxy-acetylene blowpipe 1 and a spray gun 2 feed into a flame spray head 3, which has a slotted spray orifice 4 surrounded by two parallel rows of flame ports 5.  Liquid plastisol is forced from the container 6 into the flame spray gun 2 by means of compressed air. The spray produces a surrounding low pressure area which causes the flames from the ports 5 to be drawn towards it; when the spray is cut off, the flames have no convergence, and may be used for fusing the coating; or this may be effected by a hot air blast or by oven treatment.
