Title: Improvements relating to load carrying apparatus
Inventor: EADE ROBERT FRANCIS
IPC: H03M1/00
Filed: 1964-01-02
Abstract: 1,020,845. Electric selective signalling. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Dec. 22, 1964 [Jan. 2, 1964], No. 210/64. Heading G4H. In an analogue-to-digital converter, when a sweep voltage reaches a datum level it is biased away from the datum level by the analogue input voltage and clock pulses are gated to a counter from this time until the biased sweep voltage returns to the datum level. In the particular embodiment, the analogue input voltage represents the load on a conveyer and the sweep voltage is triggered to produce sampling of the input at a rate proportional to the conveyer speed. The datum level is reached for the first time when the ramp has progressed far enough to cancel a fixed voltage from a potentiometer which ensures that the non- linear part of the ramp is avoided during counting. The counter produces a total count for a plurality of successive samplings, and a rate meter gives a smoothed average of several successive samplings.

Title: Glycidyl ethers derived from phenolic condensation products
IPC: C08G59/24
Filed: 1953-01-05
Abstract: Phenolic condensation products, obtained by reacting in presence of a cationic condensing agent a monohydric saturated phenol with a monohydric phenol substituted in the nucleus with an unsaturated hydrocarbon radical of 14-22 carbon atoms, are reacted in alkaline medium with epichlorhydrin.  The glycidyl ether products are soluble in turpentine, benzene, toluene, xylene or cumene and are hardenable in the cold or at elevated temperatures, if desired with the aid of conventional curing agents such as amines or polyfunctional acids. Suitable saturated phenols are phenol, naphthol, anthranol, cresol or xylenol, and unsaturated phenols are cashew nut shell liquid, anacardic acid, cardol, cardanol, marking nut shell liquid, urushiol or unsaturated polymers thereof.  Suitable condensing agents are sulphuric acid, anthranol, cresol or xylenol, and unsaturated phenols are cashew nut shell liquid, anacardic fluoride.  The products may be modified by treatment at 230-290 DEG  C. with fatty acids from linseed oil, soya-bean oil, dehydrated castor oil, tung oil or fish oil, or with tall oil or resin acids.  Cobalt, manganese or lead driers may be added to improve the drying properties.  The products may be copolymerized with or used as plasticizers for resins obtained from glycidyl ethers of resorcinol, catechol or hydroquinone.  In the examples: (1) a boron tri-fluoride complex was added to molten phenol.  Cashew nut shell liquid treated according to Specification 664,169, [Group IV (b)], was added.  The catalyst was neutralized with alkali, salts removed by filtration and the product dissolved in dioxane. Caustic soda was added and then epichlorhydrin drop by drop. The product was neutralized, dissolved in methyl ethyl ketone and freed from salts.  The product cured to tough films at 170 DEG  C. or at room temperatures in presence of triethylene tetramine. Example (2) is similar, using a phenol-cardanol condensate. U.S.A. Specification 2,317,607 is referred to.

Title: Improvements in methods of and apparatus for hardening the inner wall surface of hollow metallic bodies
IPC: C21D9/14
Filed: 1936-01-03
Abstract: 468,626. Hardening hollow bodies. LINDE AIR PRODUCTS CO. Jan. 3, 1936, No. 251. Convention date, Jan. 19, 1935. [Classes 72 and 82 (i)] [Also in Group XI] The inner wall of a metallic hollow body is hardened by progressively and uniformly heating successive and relatively narrow circumferential portions of the surface of said wall to a temperature above its critical range and then cooling by utilizing the heat-absorbing capacity of the rest of the body so as to establish a steep temperature gradient over the entire area of the surface. The cooling may be assisted by causing a cooling fluid to impinge on a circumferential portion of the surface in close juxtaposition to the heated portion. In the treatment of the inner wall 11 of a cylinder block 10, the latter is mounted on a hollow support 15 so as to leave openings 14. The water jackets 30 of the block may be filled with a cooling liquid. A star-shaped burner head 17 with a plurality of nozzles 28 and a baffle plate.22 to prevent the upward escape of the heat generated by the nozzles 28 is mounted on the lower end of a hollow shaft 16 provided with a mixing passage for gases entering by pipes 18, 19 and also a passage for cooling medium which enters by the pipe 20 and leaves by the pipe 21. The shaft 16 is in alignment with the axis of the cylinder to be treated and is given a rotary or oscillatory movement by the worm gear 32 and is also moved vertically downward into the cylinder by gear 33 and rack 34. Alternatively the burner may be stationary and the support 15 moved. In a modification, the burner proper is of conical form and provided with a conicalshaped baffle above, or the burner is of inverted conical form and a conical baffle is placed beneath it, the burner in this form being moved upward from the bottom of the cylinder. In a second modification the baffle plate 22, Fig. 1, is arranged below the nozzle 28 and the burner moved upwards from the bottom of the block. In a third modification, a perforated pipe connected to a supply of cold water or air is mounted on the burner either above or below the baffle plate according to where the latter is placed. The cylinder may be made of an alloy steel containing 0À35-0À45 per cent of carbon, 0À5-0À8 of manganese, 0À8-1À1 of chromium and 0À15-0À25 of molybdenum or 0À3-0À4 of carbon, 0À5-0À8 of manganese, 1À0-1À5 of nickel and 0À45-0À75 of chromium.

Title: Process for the purification of vitamin-a-preparations
IPC: A61K31/59
Filed: 1933-01-05
Abstract: Vitamin A concentrates are obtained by dissolving the initial material in a water-miscible solvent, separating impurities by cooling to a low temperature, then adding successive quantities of water with cooling to precipitate vitamin concentrates, preferably with exclusion of oxygen, and extracting the mother liquor with an organic solvent.  In examples (1) the unsaponifiable portion of the liver oil of hippoglossus vulgaris is dissolved in methanol and cooled with solid carbon dioxide in acetone, the precipitate being separated, preferably by filtration through solid carbon dioxide; additions of water are made so as to dilute the methanol to 96 and 90 per cent and then a further 15 per cent of water is added, cooling and separation of precipitated matter being effected as above described after each addition of water, the precipitates being dissolved in petroleum ether and evaporated in vacuo; a fifth product is obtained from the dilute mother liquor by adding more water and extracting with petroleum ether.  The third precipitate yields a product of the highest vitamin A content; (2) the unsaponifiable portion of the liver oil of scombresox saurus is dissolved in acetone, and the extraction of concentrates is effected as above described.

Patent GB-641379-A (GB)
Title: Improved method of producing molybdenum
IPC: C22C1/04
Filed: 1948-01-06
Abstract: Molybdenum, stated to be easily machinable, is made by working a sintered unworked or recrystallized bar thereof to elongate the grains on the average up to four times their transverse dimensions to improve cohesion.  There may be 10 to 250 grains per square mm. The powdered metal may be pressed to form a bar which is heated to 1400 DEG -1700 DEG C in an atmosphere containing hydrogen and water vapour for 1 1/2 to 3 hours to sinter it.  It may then be heated to 1450 DEG -1500 DEG C, rolled to reduce the section say from 22 x 32 mm. to 21 mm. square, heated to 1350 DEG -1450 DEG C, swaged to form a round rod, say 13.5 mm. in diameter.  This develops the grains and the rod is heated to 1600 DEG C in a protective or reducing atmosphere for 20 minutes or more to recrystallize the metal and worked to get the size required and to improve cohesion without undue elongation of the grains.  Scale may be removed with boiling caustic soda.

Title: Improvements in or relating to spraying apparatus
IPC: B05B3/08
Filed: 1947-01-07
Abstract: 620,191. Spray-producers. NORRIS, E. O. Jan. 7, 1947, Nos. 518 and 519. Convention dates, Jan. 18, 1946, and Jan. 25, 1946. [Class 69 (iii)] Liquid is supplied under the control of valve 104 to a rotating chamber 20 via a supply pipe 100. The centrifugal force executed on the liquid in the chamber 20 is sufficient to retain the liquidin the annular channel 24 where it is picked up by a rotating tube 56. The inlet of the rotating tube 56 is normally clear of the liquid level in the annular channel 24 and is lowered into contact with the liquid by movement of the trigger control 92. Liquid picked up by the tube 56 is conveyed by centrifugal force to the rotating sleeve 70, where it passes through annular slots 71 and is flung off the annular ridges 72 in a band of atomized particles. The rotating sleeve 70, with the coaxially-rotating supply tube 56, is mounted within the rotating chamber 20, as shown in Fig. 2, so that the tangent to the periphery of the ridges 72 is coincident with the horizontal axis of the chamber 20, thus producing a flat ribbon spray, as shown by the chain line. The motor 1 drives the chamber 20 via intermediate gearing at a speed of 400 r.p.m., and also drives the gear-box 41 via a flexible shaft 49 within tube 38 at armature speed of 12,000 r.p.m. Within the gearbox (shown in Fig. 5), bevel gears 46, 47 transmit the drive to the pick-up tube 56, which also rotates at 12,000 r.p.m. Lugs 66 mounted on a radial collar 69 of the supporting spider associated with the pick-up tube, drive the ball-cage 65 of the ball-race 63 at armature speed, resulting in a speed of rotation of approximately 18,000 r.p.m. of the outer portion 64 of the ball-race and the annular sleeve 70 mounted thereon. The relative motion between the pick-up tube 56 and sleeve 70 results in the curved top edge 73 of the pickup tube sweeping regularly past the slots 71, thus feeding the liquid evenly thereto. A boot 84 is fitted to the tube 38 to prevent paint travelling into the gear-box 5. Annular rings 29, 30 and an annular wire screen 35 are fitted to the front aperture of the chamber 20 to limit the angle of the spray, the liquid leaving the rotating sleeve 70 at points remote from the front aperture of the chamber being drained back into the annular channel 24 and resprayed.

Title: X-ray generator
Inventor: AMAMIYA MITSUAKI
IPC: H01L21/027
Filed: 1987-01-06
Abstract: PURPOSE:To extend the life of this device by forming the wall face of a capillary with a dielectric substance and drawing out the wall face in response to the consumption of the wall face. CONSTITUTION:When a capacitor Cd is charged and the sufficiently large voltage is applied to an insulator 8, the dielectric substance 9 facing a capillary 2 is evaporated by the creeping discharge of the capillary 2 to generate plasma 5. In this case, when an electron beam is radiated from a cathode 6 to the plasma 5, the temperature of the plasma 5 rises, the plasma density is increased, and X-rays 7 are generated. Part of the surface of the dielectric substance 9 facing the capillary 2 generates plasma by the creeping discharge, thus the dielectric substance is reduced as much. Therefore, the dielectric substance 9 is moved toward the center of the capillary 2 as much as the quantity generating plasma. Accordingly, the consumption of the dielectric substance resulting from the generation of plasma can be compensated by the drawing out of the dielectric substance.
