Title: Improvements in or relating to cathode-ray tubes
IPC: H01J29/80
Filed: 1935-01-25
Abstract: 450,973. Cathode-ray tubes. FERNSEH AKT.-GES., Goerzallee, Zehlendorf, Berlin. Jan. 25, 1935, No. 2529. Convention date, Jan. 26, 1934. [Class 39 (i)] The electron beam of a television &c. tube is modulated in intensity and deflected and is then focused on to the fluorescent screen by an electrostatic lens of two or more apertured diaphragms charged to accelerate the electrons. The cathode or an aperture in a diaphragm is focused on to the fluorescent screen and in the latter case a large indirectly heated cathode may be used. A lens of two diaphragms may be placed between the two pairs of deflecting plates or on the side of the plates remote from the cathode ; the first diaphragm is then connected to a screen surrounding the plates and to the anode of the electron gun and the second diaphragm is at a higher positive potential and connected to the fluorescent screen. In a modification, the beam formed bv the cathode 11 and anode 13 is modulated by an electrode 12 forming an extension of the cathode surface. An aperture in a diaphragm 14 is focused by a retarding lens 15, 16 on to a small rectangular aperture 18<1> in a screen 18. The ray is deflected by plates 23, 24 to form an " electron image " in the aperture 181 and this image is projected on to the fluorescent screen 22 by diaphragms 19, 20 forming an accelerating lens. Screens 17, 21 are connected to the diaphragms 19, 20.

Patent GB-937547-A (GB)
Title: Catalyst recovery process
Inventor: LEYSHON DAVID MORGAN
IPC: B01J23/94
Filed: 1961-01-23
Abstract: Copper-vanadium catalyst is recovered from the waste liquors in the manufacture of adipic acid by nitric acid oxidation of cyclohexanol and/or cyclohexanone (see Specification 572,260) by adding sulphuric or phosphoric acid to the waste liquor in an amount slightly more than equivalent to the nitrate salts present; evaporating nitric acid and water therefrom; filtering the molten residue to separate insoluble catalyst; redissolving the catalyst in water or dilute nitric acid; reprecipitating the catalyst at pH above 7 and washing the precipitated catalyst with water.  The catalyst may then be re-dissolved in dilute nitric acid and re-used.  Evaporation of water and nitric acid is preferably carried out under reduced pressure e.g. by blowing in steam at 100 DEG  to 170 DEG C., by continuous addition of fresh or partially concentrated waste liquors at 40 DEG  to 90 DEG C. or by blowing in air. The precipitation of the catalyst is preferably effected at pH 8-9 by alkali and alkaline earth metal hydroxides and carbonates, e.g. sodium hydroxide.  The process is a modification of that disclosed in Specification 756,679.

Title: Process for the manufacture of blades for turbines and compressors
IPC: B21H7/16
Filed: 1953-01-29
Abstract: 730,320. Making turbine blades; rolling. INDUSTRIE-WERKE KARLSRUHE AKT.- GES. Jan. 29, 1953 [Dec. 20, 1952], No. 2599/53. Classes 83 (2) and 83 (4). A process for the manufacture of turbine blades includes severing a preliminary workpiece from a bar of high heat resistant material, e.g. 80 per cent Ni-20 per cent Cr alloy, performing a series of shaping operations to form a vane and a serrated root without any cutting operation thereon and while the work-piece is in a cold condition. To form a solid blade the work-piece has a part thereof narrowed to form a vane section 2, Fig. 2, and is then pressed to form the vane section 3, Fig. 3, with a flattened root. The root is then pressed to the shape 4, Fig. 5, and the vane section drawn to the shape 6 between shaped rollers 7 and 8. Finally the root is serrated between rollers 9, 10, Fig. 6. To form a hollow blade the work-piece is pressed to form a cup 13, Fig. 8, the wall of which is then drawn out, as at 15, Fig. 9, and the upper rough edge 16 cut off and the vane section is then narrowed at its lower part 17, Fig. 10, and expanded at its upper part 18. Paraffin wax is then poured in the hollow vane and the vane suitably moulded between matrices, the root being serrated by rollers. The wax is removed by melting. In these processes the work-piece is initially dipped in a drawing-lac which forms a porous oil absorbing film when dry, the film being washed off the finally shaped blade.

Filed: 1960-01-25
Abstract: 897,245. Submersible electric motors. FAIRBANKS, MORSE & CO. Jan. 25, 1960, No. 2653/60. Class 35. An electric motor which operates submerged in water, e.g. sea-water, has a casing which is open at both ends so that the water may flow through and cool the motor. Water circulation is promoted by radial and axial bores 133, 129 in the motor shaft 30, and by relative motion of the ambient water forcing it through passages 125 under the edges of end-cover-plate 118. The water passes axially through the air-gap and through the stator slots in the interstices between the winding conductors. It traverses filters 144, 148 and 150, and serves to lubricate journal and thrust bearings at each end. Additional flow is permitted by holes 78, 80, and drain holes 79, 82. The winding end-turns 87, 88, 91, 92 are protected by insulating baffle rings 95, 96, and a further, perforated, cylindrical baffle 137 serves to direct the pumped water into the working air-gap. The rotor consists of several sections 37, each having a cast squirrel-cage 39, in end-to-end abutment.

In a plant employing hydrostatic pressure-generating columns 20, 21, 22 in series, vapour or gas is injected at 26 into the sterilization chamber 24 to give a partial pressure additive to that of the partial pressure of the saturated steam therein. As shown, the same columns 20, 21, 22 are used for entrance and exit of the product conveyer 2, to provide heat transfer between the leaving and entering products. Heaters 25 are also provided, with air injection at 27 into the intermediate pressure spaces. Apertures 11 interconnect the column arms. The pressure of air injections may be controlled by float valves on the column surfaces. The individual column heights may differ. In a modification there is a second series of columns for product exit, there being vapour or steam heating injections into bottoms of the entrance columns and cold water and compressed air injections into the tops of the exit columns, or steam feed-backs from the tops of the exit columns to the bottoms of the entrance columns which may also be directly or indirectly steam heated.

Abstract: 1282224 Nuclear reactor rod control; controlling reactors WESTINGHOUSE ELECTRIC CORP 21 Jan 1970 [13 Feb 1969] 2848/70 Headings G4H and G6C In a nuclear reactor where banks of control rods are raised or lowered each in a series of steps by clock pulses one bank after another with a period of overlap between adjacent numbered banks, controls signals indicating which banks are to move are generated by a series of preset decoders reading a counter which is stepped one count for each step of the bank(s) being currently moved. In Fig. 2, logic 10 receives a raise of lower disection signal DIR and provides a direction signal c and strobe signal synchronous with the clock pulses to switching circuit 16 providing bank control signals. The first and last rods of each bank send signals Po and Pf respectively to logic 10 marking the beginning and end of the sequential movement of rods in one bank step. Logic 10 generates either a forward F or reverse R signal stepping the two-way counter 12 one step for each completed step of a bank or both banks. Decoders 14 reading the counter supply to switching circuit 16 signals indicating the start of the next bank and then the finish of the present bank. If a change of direction is called for during a bank step change the sequence of rod movement for that step is completed before a change in direction is made. The automatic control may be manually overridden.

A bowling alley scorer or indicator detects the presence of a pin by its disturbing effect on the balance of two mutual inductances having their secondaries connected in opposition. Each pin detecting arrangement consists of two primary 25, 25a, 37 and 37a and two secondary 26, 26a, 38 and 38a coils wound on non-conductive formers. The balancing inductances 37, 38 and 37a, 38a may be remote from or otherwise magnetically shielded from the detecting inductances 25, 26 and 25a, 26a. The secondaries of both inductances or of only the balancing inductances may be axially displaceable relatively to the primaries to effect balancing. The secondaries 26, 38 and 26a, 38a are connected in opposition so that amplifiers 54, 54a and relay coils 56, 56a are only energized on unbalance caused by a correctly spotted standing pin 65, 65a. The primaries are energized by an A.C. source 49. The relays may light the lamps 59, 59a or they may operate a scoring device. It is stated that pins containing a very small amount of magnetic material can be effectively detected.
