Title: Improvements in or relating to cathode ray tubes or the like
IPC: H01J29/84
Filed: 1951-05-18
Abstract: 685,821. Cathode-ray tubes. RAULAND CORPORATION. May 18, 1951 [May 19, 1950], No. 11645/51. Class 39(i) In a cathode ray tube the offset anode 21 has a beam defining aperture 24 and a fluorescent coating is provided on a surface shielded from direct impingement by the beam but disposed so that when the beam strikes the interior surface of the anode 21 the coating fluoresces and can be observed through a transparent neck portion of the envelope and adjustable beam deflecting means such as the magnetic means shown enable the beam to be directed through the aperture 24. It is state( that the fluorescence is due to impingement by primary electrons reflected at anode 21 and/or by secondary electrons ejected from anode 21 under primary electron bombardment. The fluorescent coating may be on the external wall of anode 21 at 31, and/or on the interior surface of the neck 10 at 32, or at any other suitable place adjacent the gun electrodes, such as on rods 13 or lugs 22. The device preferably incorporates an ion trap, the mixed beam of electrons and ions being deflected in one direction by a transverse electrostatic field component between offset electrodes 18, 21 and restored to the axis by a magnetic field produced by permanent magnet 27. A second permanent magnet 28 is preferably provided to correct any overshooting of the beam, and the two magnets 27, 28 which have oppositely directed fields are mounted on a member 26 which may be rotated or moved axially to adjust the magnetic deflection so that the electrons but not the ions pass through aperture 24. The electrodes 14, 18, 21 are carried by lugs 15, 19, 22 from glass rods 13 held in the envelope by suitable means (not shown) and terminal connections 25 connect the anode 21 to the internal wall coating. 14 is the control electrode and cathode 17 is mounted within it and spaced therefrom. Specification 678,546, is referred to.

Title: Improvements in marine power plants
IPC: F01K7/02
Filed: 1931-04-23
Abstract: 367,626. Motor power plant. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.- (Akt.-Ges. Brown, Boveri, et Cie ; Baden, Switzerland.) April 23, 1931, No. 12035. [Class 110 (iii).] A marine steam power plant comprises a reciprocating engine a and auxiliaries d the exhaust steam from both a and d being fed to a turbine c which through gearing h drives the propeller shaft b. Change-over valves e, g connect the engine or auxiliaries exhausts either to the turbine c or a condenser f. Steam from the intermediate cylinder of the engine is fed to a feed-water preheater v and passes on to the turbine. In place of the gearing h electrical transmission or hydraulic gearing may be used. The coupling i may be of any type. A pressure regulator u ensures approximately constant back pressure for the auxiliaries when they exhaust to the condenser. A live steam pipe k supplies the engine and a pipe l the auxiliaries. In an alternative arrangement the exhaust steam from the auxiliaries is led into the exhaust pipe from the engine a, so that the second change-over valve g is dispensed with. The change-over valves may be operated automatically. The turbine may also drive a dynamo for supplying current to the ship. The motor and dynamo in the case of electrical drive from turbine to the shaft b are disconnected electrically on diminution of engine speed. Live steam may be fed to the turbine through a pipe m. The turbine may have separate nozzles for the exhaust steam from the engine and the auxiliaries to provide for different steam pressures. The exhaust from the auxiliaries d may be led to the L.P. cylinder of the engine a.
Patent GB-474299-A (GB)
Title: An improved automatic regulating apparatus for a gas compressing installation
IPC: F04B41/02
Filed: 1936-04-28
Abstract: 474,299. Regulating compression. HEYWOOD, C. F. April 28, 1936, No. 12074. Convention date, April 29, 1935. [Class 8 (i)] A single compressor supplies a number of reservoirs working at different pressures, the compressor automatically supplying each reservoir as soon as a certain quantity of air has been withdrawn therefrom and at other times working under no load. Fig. 1 shows reservoirs 5, 6 adapted to supply air for braking and for starting the Diesel engine of a vehicle, supplied from a two-stage compressor 1. Each reservoir has a control device 43 comprising a valve operated by a Bowden wire 43a for supplying air from the reservoir, and an inlet valve regulated for the desired pressure controlling the supply from one of the compressor stages. Piston valves 12 in a regulating device 10 are subject on their lower faces to the reservoirs and on their upper faces normally to atmospheric pressure and to the delivery pressure of one of the reservoirs through pipes 44a, 46a. When both reservoirs are filled, the valves in their upper positions allow the air from the first stage to pass through grooves in the valves to the atmosphere by a passage 10c, while the air from the second stage is byepassed through a pipe 2e. In modifications, ball valves replace the piston valves. Fig. 5 shows one of three reservoirs supplied by branches 2 from a common compressor discharge line through ports 49a in pistons which are forced up by the internal pressure when the filling is completed, and so close the valves. When air is drawn off by opening a valve 50a, a pipe 51 leads air to the top of the corresponding piston valve, allowing the port to be re-opened. A branch from the pipe 51 acts on a ported piston controlling an outlet to atmosphere for the compressor.

Title: Improvements relating to lubricating apparatus
IPC: F16N21/04
Filed: 1922-05-01
Abstract: 198,187. Partridge, W. J., and Mills, H. May 1, 1922. Couplings, disconnectible; with valves and cocks.-Means for coupling the grease-gun of lubricating apparatus to the part to be lubricated so as to avoid leakage of lubricant after uncoupling comprises a two-part body a, b connected to a pipe f leading to the lubricant container, and having a cylindrical or conical valve c adapted to be rotated to align its passage i with the perforation j in the body b by a two-part, sleeve n, o, rotation of which, whilst rotating the valve c, causes the flange w forming its eccentric end aperture v to engage in the groove y on the spigotx as described in Specification 191,919. The body and sleeve may, however, be, arranged concentrically and any convenient means provided for securing the coupling to the spigot. The sleeve n rotates the valve c through a spring-pressed bush l sliding on the hexagonal end of the valve c and having a peg p working in a circumferential slot q in the body a and a longitudinal slot p in the sleeve n. The slot q has a recess s in which the peg p normally engages under the influence of the spring g so as to secure the parts against relative rotation until insertion of the spigot x pushes in the bush l and releases the peg p. A peg t in the body a engages a slightly inclined circumferential slot u in the sleeve n so that rotation of the sleeve to couple the parts draws the spigot x tightly against the leather pad 2 on the end face of the valve. In Fig. 4 the pipe f is vertical, a slot 3 in the sleeve n, o allowing rotation of the latter. The bush l is dispensed with, the valve c, which can move axially as well as rotate, having the peg p secured to its cylindrical head k. In a further modification, Fig. 7, the parts are secured against rotation by the square lower end of the pipe f engaging a recess in the slot 3, the sleeve n, o having to be slid along the body a against the action of the spring g to release the pipe f before it can be rotated by the screwed pegs 4.

Abstract: 1,014,010. Clips. B. VOUMARD. March 23, 1964 [March 25, 1963], No. 12266/64. Heading E2B. [Also in Division F2] A bearing, for the balance wheel of a watch, for example, has a body 2 with inner grooves 13, 14 therein which receive diametrically-oppositely located lugs 7, 8 of an elastic ring 6, each groove 13 or 14 having curved recesses 20, 21 or 23, 24 with inwardly projecting portions 22 or 25 therebetween, which prevent accidental angular displacement of the ring 6 from the working position. The ring 6 is permanently assembled to a setting 5 by being forced over a flange 19 thereof and maintains a pierced-stone 3 against an annular face 9 of the body 2 by urging the setting 5 against the stone 3. The stone 3 is engaged by a pintle 1 of a balance wheel. On assembly, the stone 3 is positioned in the body 2 and the assembly, comprising the ring 6, setting 5 and stone 4, is mounted in the curved recesses 21, 24 via a recess 26 which extends from the recess 24. A tool, inserted in a hole 27 or 28 in the lug 7 or 8, is used to angularly displace the ring 6, the latter being distorted as the lugs pass the projections 22, 25. Further angular movement of the ring 6 positions the lugs 7, 8 into the curved recesses 20, 23 of the grooves 13, 14, thus the ring 6 is located in the required working position.

Abstract: 982,385. Indexing station for a chain conveyer. BAGSHAWE & CO. Ltd. June 21 1963 [March 30, 1962], No. 12300/62. Heading B7L.  A chain conveyer indexing station has a plurality of indexing positions, each of which has an arm 119 fixed to a pivot 112 and integral with a stop dog 118, the pivot also carrying a latch lever 111 co-operating with latch 103, a lever 116 connected by linkage 117 to a ramp 131 which disconnects chain drive to a trolley, and a counterweight 115 on an arm 114. As trolley 120, 121, 122 leaves a forward position it depresses arm 119 to position 126 to raise stop dog 118 and ramp 131, and a pin 113 engages latch 103 to hold the dog &c. raised. The following trolley is thereby halted and drive disconnected. The halted trolley holds a lever 133 depressed against a counterweight to cause, through linkage 138, the raising of a stop dog and ramp at the next preceding station to halt the next trolley and so on. To release a trolley from the forward position, a solenoid 105 at this position is energized to withdraw latch 103, the counterweight 115 withdraws stop dog 118 and lowers ramp 131 to reconnect the drive to move the trolley. The counterweight 136 raises lever 133, Fig. 4, as the trolley leaves to release the next trolley from the preceding station and so on. The first trolley depresses a lever 142 to ensure that lever 133 rises and as it leaves the first position it depresses arm 119 to again raise dog 118 and set the mechanism to halt the next trolley. In Fig. 8, not shown, the arm 119 is connected to stop dog 118 through a linkage system so that the dog is situated aft of the rear wheel of a train of trolleys and is therefore not raised between the wheels of the train. In Fig. 9, not shown, a stop dog under manual control at each position can halt a trolley as desired without upsetting the automatic setting of the whole station when the manual control is released. Specification 948,950 is referred to.
Patent GB-711352-A (GB)
Title: A method of producing oil from vegetable or animal material
IPC: C11B1/02
Filed: 1951-05-25
Abstract: Vegetable or animal material containing oil enclosed in cells is mechanically disintegrated into a flowable mass, and the latter is brought into rapid movement in the form of a jet which is rapidly braked in a liquid mass by means of internal liquid friction, so as to burst the cells and produce a homogeneous unstable water-in-oil dispersion from which the oil is finally separated.  The final separation may be effected by settling or by centrifuging or a combination of these methods.  Free oil may be added to raw material containing a low percentage of oil to prevent the formation of a stable dispersion, either prior to or during the homogenization, or oil may be added to the stable dispersion, the mixture being vigorously stirred.  The amount of added oil may exceed the amount of water and/or cell material in the dispersion.  When using material of a low water content, water or an aqueous solution may be added to the material, either at the stage when the material is in the form of an oil-in-water dispersion or when it is in the form of a water-in-oil dispersion. The flowable mass may be sprayed in the form of a preferably rotating jet into a whirl chamber or other homogenizing device filled with liquid, so as to burst the cells.  If desired, the material may be heated prior to or during the homogenization. Where it is desired both to add water and to heat the material, water vapour, superheated if necessary, may be employed, preferably during or after the mechanical disintegration.  The pH of the material may be adjusted so that it approaches the iso-electric point of the dispersion.  If desired, the heating may be carried out in a plate heat exchanger, which may be placed between the homogenizing device and the centrifuge.  In order to prevent clogging the sludge space of the centrifuge by coagulated proteins, a layer of salt water, preferably of 10 per cent. salt content or more, may be introduced near the bowl wall.  The process is applicable to the recovery of oil from fish and whale livers, fish and whale meat, unrefined swine fat and olives and other oil-bearing fleshy fruits.  Specification 670,101 is referred to.
