Title: Improved process of protecting metal surfaces by electrodeposition
IPC: C25D9/06
Filed: 1937-03-30
Abstract: 492,900. Electrolysis. CROSSE & BLACKWELL, Ltd., SUMNER, C. G., JOHNSON, R. I., and CLAYTON, W. March 30, 1937, Nos. 8966/37 and 7732/38. [Class 41] A conductive surface (e.g. tinplate) is coated with an aluminous compound by anodic treatment in an aqueous medium containing in solution a compound of aluminium such that the ions containing the aluminium are negatively charged, e.g. sodium aluminate. The alkalinity of the solution may be reduced to such a value that the aluminous compound is only just held in solution in the absence of electrolysis, e.g. by addition of sodium bicarbonate, sodium dihydrogen phosphate or sodium bisulphite, or a depolarizer such as a reducing agent may be added. Also, the solution may contain a lacquer in dispersion, or colloidal material such as sodium silicate or gelatine, which is deposited simultaneously with the aluminous compound, or the film may be subsequently covered with lacquer, wax, cellulose, or like coating material by electrodeposition from an aqueous dispersion or by application in liquid form as in organic solvents, or by treatment with a dispersion coagulable by aluminium compounds, such as an emulsion of lacquer in dilute ammonia. In the case in which aluminous compound and lacquer are electrodeposited simultaneously, the colour and brightness of the film may be decreased by such additions as sodium hydroxide or ammonia, alkali-metal tartrate or citrate, or sodium silicate, and the brightness increased by addition of an emulsifying agent such as rosin soap, and both may be controlled by regulating the proportions of lacquer and aluminate and of the acidic constituents of the lacquer. The results obtained with various specified lacquers are described. The film may be stoved and, if desired, dyed in the manner usual for anodicallv-oxidized aluminium. Specifications 455,810, 479,681, and 490,851 are referred to.
Patent GB-1457613-A (GB)
Title: Radiation sensing device
IPC: G01T1/24
Filed: 1974-02-28
Abstract: 1457613 Semiconductor devices GENERAL ELECTRIC CO 28 Feb 1974 [29 May 1973 (2)] 9065/74 Heading H1K A radiation detector for an imaging array comprises two electrodes 14, 15 (Fig. 1C) capacitively coupled to adjacent portions of a semiconductor substrate 11 so that appropriate voltages thereon will induce depletion regions 21, 22 in the underlying substrate surface at which regions minority carriers generated by radiation incident on the device can be stored. Reduction of the voltage of the first electrode 14 causes the underlying depletion region 21 to collapse, decanting the charges stored therein into the depletion region 22 beneath the second electrode 15, e.g. via the depletion region 23 associated with an intervening p<SP>+</SP> type region 20 (the surface layer 11a of the substrate 11 being n type). Reduction of the voltage on electrode 15 then causes the stored charges to be injected into the layer 11a and they are collected at reverse biased pn junction 27 between layer 11a and underlying p<SP>+</SP> layer 11b. The current thus generated charges integrating capacitance 18, which includes the capacitances associated with electrodes 14, 15, and permits read-out. The collected carriers are prevented from being recollected at the reconstituted depletion regions 21, 22 on reestablishment of the original voltages on electrodes 14, 15 by the presence of junction 27. The collecting junction 27 may be shortcircuited or may be replaced by a Schottky barrier. In a modification collection is carried out at the junction between the substrate and a surface region (125) Figs. 8A-8C (not shown) located alongside the second electrode (115). Fig. 9 shows 4-by-4 imaging array employing a plurality of devices 151 of the type described above, the respective first and second electrodes 161, 162 of each device being connected to corresponding row and column lines X 1 -X 4 , Y 1 -Y 4 . When this array is applied to the Fig. 8 modification described briefly above a common gridshaped p<SP>+</SP> collecting region is provided for all the individual devices. The operation of the array is discussed in detail and preferred manufacturing steps are described.

The head of each screw 12 is so placed as to prevent the springs 9 that urge the chasers outwardly from-coming out of the slots 8.
Patent GB-944165-A (GB)
Title: Improvements in or relating to percussion fuzes for unrotated projectiles
IPC: F42C1/08
Filed: 1960-02-17
Abstract: 944,165. Ammunition fuzes. GEB. JUNGHANS A.G. Feb. 17, 1960 [Feb. 17, 1959], No. 9185/63. Divided out of 944,164. Heading F3A. A percussion fuze for unrotated projectiles in which an inertia sleeve 114 is coupled with a thrust sleeve 115 which arms a rocker plate 141 of the primer carrier is made safe against premature arming by a lever 134 having a rear arm bearing against the sleeve 115 and a front arm 137 bearing against the sleeve 114 when in the safety position, sleeve 114 having a milled flat 138 against which arm 137 can bear when the lever 134 is rocked by the rear end of sleeve 114. Also the sleeve 115 is provided with a groove 138b into which the rear arm 136 of the lever can swing. As in Specification 944,164 a finger 123 extends rearwardly from the sleeve 115 to immobilize the plate 141 and an escapement pallet 125 until positive acceleration of the projectile has ended. When the projectile fitted with the fuze is fired, an inertia pin 120, on which is an adjustable weight 121, sets back against its spring 122 and before reaching its rearmost position rocks a safety lever 129, Fig. 2, thus releasing the inertia sleeve 114. Sleeve 114 then slides into sleeve 115, and a spring 119 moving into the groove 118 of sleeve 114 couples the two sleeves together. When acceleration ceases a spring 116 moves the two sleeves forwardly withdrawing the finger 123 from the plate 141 and the escapement pallet 125. A torsion spring 145 then swings the primer 146 to the armed position in line with the striker 113, so that if impact occurs the striker pin is driven against the primer. If the fuze is dropped on its nose during transport, the pin 120 and the sleeve 114 remain in the safe position. The sleeve 115 could move forwardly and so withdraw the safety finger 123, but for the presence of lever 134 of which arm 136 extends into the path of sleeve 115, the lever 134 only being rocked aside by rearward movement of sleeve 114.

Abstract: 738,866. Feeding sheets. GODDARDS & CAWLEY, Ltd., and BEACOCK, S. April 2, 1954 [April 2, 1953], No. 9239/53. Class 100 (1). Pile supports.-In a machine for applying specimen or sample tabs to cards &c. by gumming, the tabs are supported in piles in a compartmented magazine A comprising a number of flat vertical plates 5, 6, 7 which are held in spaced parallel relationship, and flat strips 11 are arranged between each pair of plates so that they can be adjusted towards each other to subdivide the spaces between the plates to accommodate the piles of tabs. As shown, screw-threaded rods 9 pass through holes in the plates which are held spaced apart by pairs of nuts 10 engaging opposite faces of each plate. The subdividing strips 11 are each secured to a block 12 which can be secured by a screw 16 to a rod 13 extending through slots 14 in the outer plates 6, 7 and secured in adjusted position by nuts. The piles of tabs may be supported within the magazine by the table on which the magazine rests, if the machine is of the type wherein the tabs are separated by suction grippers as described in Specification 730,099. As shown, the magazine is for use in a machine of the kind described in Specification 720,868, [Group XV], and is carried by adjustable supports 1, 2 on a vertically reciprocating frame 3, the various piles of tabs resting on stationary supports 4 so that the top tabs adhere to a gummed card supported over the magazine when the latter is depressed relatively to the supports 4. The gummed card can be supported by elements 17 projected upwardly from casings 19 by springs, these casings being adjustably secured by screws 22 to rods 23 also passing through the side slots 14.
Patent GB-844095-A (GB)
Title: Improvements in or relating to the purification of gases
IPC: C01B17/16
Filed: 1958-03-24
Abstract: H2S is selectively absorbed from gases containing H2S and CO2 by washing them with an aqueous solution of di-potassium hydrogen phosphate containing at least 2 and preferably 5 gram molecules of the salt per litre, the time of contact between the gases and the solution being such that all the H2S is absorbed.  The contact time may be between several seconds and one minute and the treatment is preferably carried out at superatmospheric pressure, e.g. 20 kg/cm2. A solution of tetrapotassium pyrophosphate containing dipotassium hydrogen phosphate as a product of hydrolysis may be employed in the treatment.  The solution leaving the absorption step may be regenerated by reducing the pressure on the solution and simultaneously agitating it or dividing it into fine streams or drops, and/or subjecting it to the stripping action of an inert gas. CO2 absorbed in the solution may for the most part be removed from the solution before regeneration by treating it with a portion of the H2S obtained in the regeneration thereby obtaining a purer hydrogen sulphide from the subsequent regeneration.  To obtain in the regeneration H2S almost free from CO2, the solution before it is returned to the absorption step and after it has been regenerated as described above is heated to reduce its bi-carbonate content so that the solution leaving the absorption step will have a low CO2 content.

Filed: 1969-02-21
Abstract: 1,206,072. Making rear axle casings; stamping. M. NAKAMURA. 21 Feb., 1969, No. 9409/69. Headings B3A and B3Q. A method of making a rear axle casing comprises reducing the diameter of two ends of a steel tube without altering the centre portion thereof and applying pressure to the exterior of the tube against a controlled interior pressure until the material of the tube is deformed to the required shape. The ends of the tube are reduced by rotary swaging and the centre portion of the tube may be expanded by internal hydraulic pressure, Fig. 3 (not shown), to reduce the wall thickness of the centre portion of the tube prior to forming it in dies 17, 18 by hydraulic pressure. The ends of the tube are held by chuck devices 13 and plugged by means 14, 15, the means 15 having a fluid passage 16 by which the hydraulic pressure is applied. The process is carried out at ambient temperature. The portion 19 of the formed tube is removed to form an internally flanged opening to which a differential housing (22), Fig. 7 (not shown), may be secured.

Abstract: 661,699. Tea manufacture. BAKE, A. M. H. April 6, 1949 [May 10, 1948], No. 9423/49. Class 129. In the manufacture of black tea before the leaf is fermented, i.e. before cell-rupture, it is brought to a temperature, e.g. between 50‹ F. and 122‹ F., which is best for fermentation, dependent on e.g. the flavour, taste and colour it is desired to incorporate in the finished product, the preheating preferably being carried out in a more or less saturated atmosphere of the desired temperature. The leaf may be preheated by contact with an air stream, or by radiation or electrical short waves or by contact with heated surfaces. The thinly spread leaf 2, either fresh or withered, is fed from the left into a cabinet 1 in which the desired temperature and humidity is maintained, and is caught between two moving strips of gauze 3, 4 which carry it in a sinuous path over one or more revolving drums maintained e.g. by water at the desired temperature. The rolling or cellrupturing machine for which the leaf is destined may be brought to the same temperature as the leaf.

Abstract: 769,370. Making sliding clasp fasteners. WALDES KOH-I-NOOR, Inc. April 1, 1955, No. 9546/55. Class 83 (2). Predetermined lengths of slide fastener chain having an element-free portion at one or both ends are produced from a roll of continuous fastener chain by intermittently feeding the continuous fastener chain past element-removing means and cutting-off means, spaced therefrom, operated simultaneously while the chain is at rest. Continuous fastener chain C is drawn from a roll 28 by rollers 23, 25, 27 intermittently chain by intermittently feeding the continuous fastener chain past element-removing means and cutting-off means, spaced therefrom, operated simultaneously while the chain is at rest. Continuous fastener chain C is drawn from a roll 28 by rollers 23, 25, 27 intermittently driven from a main drive shaft 43 through an adjustable crank and a rack, Fig. 6 (not shown), and clutch means, the roller 27 being driven slightly faster than the rollers 23, 25 to maintain tension in the fastener chain C. Interconnected fastener elements 12, 13 are removed over a short length a1 of the chain C while the chain is at rest by a punch 35 positioned before the roller 23 and reciprocated by an eccentric 36 driven from the main drive shaft 43. The punch 35 cuts through the coupling heads of the elements 12, 13, which drop into a receptacle 39, any remnants of the elements on the tape beads being removed therefrom by air nozzles or brushes 81, 82. Simultaneously with the operation of the punch 35, a blade 40, spaced from the punch between the rollers 25 and 27 and driven from the shaft 43, severs the fastener chain at x to provide a length thereof with an element-free extension a at one end. By severing the chain mid-way of the element-free length, fastener lengths with element-free extensions at both ends may be formed. To form a length of fastener chain with an elementfree extension a<SP>x</SP>, Fig. 7, at one end and an element-free gap g near the other end, a suitablyshaped punch D is used to remove the requisite elements. To vary the predetermined length of fastener chain produced, the rotation of the feed rollers may be varied and a tension roller 75 between the rollers 23, 25 suitably adjusted.
