Abstract: 1,181,536. Length measuring systems. GERHARDT MESSMASCHINENBAU. 5 July, 1967, No. 31001/67. Heading G4H. In apparatus for measuring length by generating a voltage representing the length and comparing it in a comparator 3 with a variable reference voltage derived from the count in a counter 14, 15 the comparator 3 determines which of two pulse trains 6, 7 are fed to the counter 14, 15 (depending on the sense of the difference between the reference voltage and the measurement voltage) so that the counter 14, 15 counts in the direction which reduces the difference. In the embodiment described a measurement sensor 2 is fed with A.C. current from a generator 1 to supply a measurement voltage to comparator 3. The voltage from generator 1 is also fed to a pulse shaper 5 which generates positive and negative square wave pulse-trains 6, 7. The comparator 3 controls a switch 10-either a three position switch or a full wave rectifierso that one of the pulse trains is fed to the counter, the count being stopped when the inputs to the comparator are equal. The two decade counter 14, 15 is connected to transformers 16, 17, a number of tappings on the transformers, in accordance with the number of pulses counted, being brought in to step the reference voltage. The count is displayed on indicators 18, 19. To measure the maximum or minimum of a series of inputs, switch 8 or switch 9 may be opened so that the counter can only be incremented in one direction.

Abstract: 890,247. Making composite panels for heat exchangers; working at specified temperatures. OLIN MATHIESON CHEMICAL CORPORATION. Sept. 12, 1960 [Feb. 26, 1960], No. 31344/60. Classes 83 (2) and 83 (4). A method of working a composite panel formed from two unified component sheets with the sheets being different alloys of the same metal and having different elastic limits, comprises heat treating the panel above the recrystallization temperature of the two component sheets to anneal the sheets fully, hot rolling the panel at a temperature above the recrystallization temperatures of both of the sheets upon entry to the mill rolls and discharging the panel from the rolls at a temperature between the recrystallization temperature of one of the sheets and the recrystallization temperature of the other of the sheets. In an embodiment a heat exchanger panel is made by interposing a pattern of stop weld material 4 between a pair of aluminium alloy sheets 2, 3 of different alloys and the sheets are pressure welded together by heating to between 900 ‹ and 950‹ F. and rolling to at least a 65% reduction to form a blank 1. Subsequent to the pressure welding operation or immediately prior to the ultimate reduction of the blank 1 to final gauge, the blank is heated above the recrystallization temperatures of both alloys and further reduced to gauge by hot rolling, the rate of rolling being such that the elongated blank is discharged from the rolls at a temperature between the recrystallization temperatures of the alloys, namely about 520 ‹ to 620 ‹ F. In the composite panel obtained one of the aluminium alloy sheets is in the annealed state and the other in a work-hardened condition. To obtain a configuration of tubular passages with increased resistance to ice pick damage the panel is placed between rigid platens 10 and 11 and expanded with fluid pressure to the configuration shown in Fig. 5. The softer alloy is expanded into a semi-hexagonal configuration 15 and the harder alloy into an arcuate configuration 13. In another embodiment a composite panel of different aluminium alloys is heated, prior to rolling to final gauge, above the recrystallization temperatures of the different aluminium component sheets to a temperature between 980‹ to 1000‹ F. whereat the ductility or plasticity of both component sheets is the same. The composite sheet, at the elevated temperature, is then rolled whereby the same elongation is obtained in both component sheets to produce a flat composite sheet without curvature or bowing. As hitherto the composite sheet is discharged from the mill rolls at a temperature between the recrystallization temperatures of the component sheets. Specification 759,804 is referred to.

Title: Crystalline forms of 6-2-1-aminocyclohexyl acetamido-penicillanic  acid
IPC: A61K31/43
Filed: 1972-12-13
Abstract: 1419257 Crystalline forms of 6-[2-(1-aminocyclohexyl) - acetamido] - penicillanic acid AMERICAN HOME PRODUCTS CORP 13 Dec 1972 [16 Dec 1971 13 Oct 1972] 31657/75 Divided out of 1419256 Heading C2C The invention comprises a form (type A) of the title acid having absorption in the infra-red spectrum at 1655 cm<SP>-1</SP> and a second form (type B) having absorption at from 3300 to 3400 cm<SP>-1</SP> and at 1690 cm<SP>-1</SP>. In crystallizing the 6-[2- (1 -aminocyclohexyl )acetamido]penicillanic acid, mixtures of water and water-miscible organic solvents such as alcohols, ketones, nitriles, ethers or esters are employed. In general, a solution of the penicillin in a small volume of water, i.e. a concentrated aqueous solution of the penicillanic acid, is treated slowly with the solvent, with or without seeding, until crystallization is complete. The crystalline form obtained depends on the conditions employed during crystallization, such as concentration, agitation, and temperature, but particularly on the composition of the solvent mixture, and whether Type A, Type B, or no seed is employed. For example, in experiments using water-acetonitrile mixtures without seeding, crystalline Type B is obtained while seeding with Type A produces a crystalline Type A product. Using water-tetrahydrofuran without seeding, the product is crystalline Type B, and using waterisopropyl alcohol with Type A seed, the product is crystalline Type A. Under the particular conditions employed, aqueous acetone, methyl ethyl ketone and ethyl acetate afford mixtures of crystalline Types A and B, with Type A predominating. Pharmaceutical preparations active against gram-positive and gram-negative microorganisms contain the penicillanic acid (Type A and/or Type B) as active ingredient. Administration is orally or parenterally.

Title: Improvements in oil burning systems
IPC: F23C99/00
Filed: 1923-12-18
Abstract: 226,961. Shore, W. E. Dec. 18, 1923. Spray and vapour burners; vaporizing-appara tus; oil supply.-An oil burner projecting into the combustion chamber of a furnace is cooled anc the atomizing device heated by circulating through their hollow walls a fluid medium such as a high grade lubricating oil capable of being heated to from 400 to 500‹ F. without vaporizing or carbonizing. In the apparatus shown, the fluid medium is circulated by a gear-pump 21 through connected annular chambers 3, 4, 5, in the hollow wall of the bell-mouthed burner con duit 1 and through the jacket 14 of a rotary atom izing device 13. The fluid medium may bE diverted through a loop 31 in the feed-water heater 32 if excessively hot, or through a loop 33 in the furnace if insufficiently heated. It may also be diverted through a loop 34 in the fuel tank 26 to render the fuel more fluid. The rotary atomizing device 13 comprises an eccentrically journaled vane rotor arranged in a cylinder 15 which is connected by a pipe 30 to a regulable oil and air mixing valve 29. The valve 29 is connected to a vacuum tank 20 which is fed with oil from the tank 26. Any unatomized oil is returned from a chamber 17 in the base of the atomizing device 13 through a trap 19 to the tank 20. Vapours arising from the fluid circulating medium are conducted from an expansion chamber 23 through a pipe 24 to the intake chamber of the atomizing device. When starting the apparatus a valve 12 at the entrance to the conduit 1 is closed and a bye-pass 35 connecting the discharge and intake chambers of the atomizing device is opened. The circulation of the atomized oil by the operation of the rotor renders the oil sufficiently volatile to burn when the valve 12 is opened. The fuel in the tank 20 may be heated initially by an electric heater.

Title: Improvements in or relating to automatic rifles
IPC: F41A19/43
Filed: 1929-10-18
Abstract: 334,424. Revelli, B. A. Oct, 31, 1928, [Convention date]. Breech actions, sliding barrel and breech-block; firing-appliances; safety appliances; trigger guards.-A short-recoil automatic rifle is made with a sliding striker 4, Fig. 1, situated within the breech-block 3 and connected thereto by a torsion spring 12 which rotates the breechblock to lock it by means of lugs 3a to the barrel 5. The ends of the spring 12 are bent in to the axial direction and fit into recesses in the breech-block and striker, respectively. When a shot is fired, the barrel 5 recoils against a short spring 6, and the stem 3a, Fig. 4, of the handle 14 of the breech-block comes against a small wheel 13 on the breech casing and the breech-block is turned round thereby to unlock it from the barrel and bring the stem 3<a> in line with a longitudinal groove 2<c> in the casing. The breech-block then continues its recoil against a spring 11, and at the same time cocks the hammer 18. The return stroke of the breech-block feeds a fresh cartridge into the barrel, and at the end of the stroke the spring 12 relocks the breech-block. A sleeve 113 on the barrel can be rotated to either of two positions. In one position, teeth on this sleeve are opposite recesses in a part 7 of the breech casing and the barrel is free to recoil, as stated above. In the other position, the teeth of the sleeve lie opposite teeth on the part 7 and prevent the recoil of the barrel and the automatic action resulting therefrom. The breech action can then be worked by the side handle 14 in the ordinary non-automatic way. The hammer 18 is pivoted at 19 and carries a sliding spring detent 25 which snaps under a fixed ledge 26 when the hammer is cocked by the recoil or opening movement of the breech-block. The trigger 20 is pivoted at 21 and a finger 22 is pivoted to the trigger at 23. When the trigger is pulled, the finger 26 pushes the detent 25 off the ledge 26. During automatic action, the recoil is so rapid that the hammer is cocked before the trigger is released; the detent 25 then snaps under the finger 22 and, when the trigger is released, slips up to the ledge 26 in readiness to be pushed off therefrom by the next pull on the trigger. The hammer may be held at safe by a pivoted catch 30, and when so held, the detent 25 is slightly below the ledge 26. The firing mechanism and a depending magazine 17 are mounted in a trigger-guard 15 secured to the stock 1 by screws 16.
