IPC: E05B63/18
Filed: 1924-07-18
Abstract: 221,779. Rheinische Tiirschliesserfabrik Boge & Kasten Ges. Sept. 12, 1923, [Convention date]. Night-latches.-A night latch in which a spring latch is operated from outside by a revolving barrel lock and from outside by a handle follower, or a second revolving barrel lock, is provided with a blocking slide for the latch bolt operated directly by the followers of the outside revolving barrel and the inside handle or revolving barrel. The slide may be arranged so that when moved to blocking position by the outside revolving barrel follower, it cannot be released by the inside follower. The latch bolt f has a. head f<1>, a a shank q upon which is mounted the shooting spring h, and a flange f<2> at each side at the end of the, bolt for engagement with the followers. It also has a slot p with enlargements r<1>, r<2> in which works the stud. q on the sliding bolt o, which has a flange s at its upper end for engagement by the followers. Fig. 1 shows the bolt, f in its shot position with the slide o lifted by the engagement of the follower k' on the inside handle spindle with the flange s. so that the stud q has been lifted out of the notch r<1> into the long part of the slot p. By continuing the rotation of the inside knob i, the follower k<1> engages the flange f<2> on the bolt and withdraws it, and the slide o drops so that the stud q engages in the notch r<2> and locks the bolt in the withdrawn position. Actuation of the bolt by the follower m<1> carried by the hub m and actuated by the connector-bar n<1> attached to the outside revolving-barrel lock n is carried out in the same way. The follower m<1> is shorter than the follower k<1> so that when the follower m<1> is in its position of rest, as in Fig. 4, operation of the slide o by the follower k<1> is not prevented. The slide o may be held in adjusted position by a spring plunger, in which case it requires positive operation to engage the notches r', r<2> by backward rotation of the followers to engage the stud q and so move it. A notch u is cut in the flange s, Fig. 7, to accommodate the end of the follower k<1>, so that when the slide o is moved downwards by the follower m', it is impossible to release the slide by the follower k<1> when it has been moved into blocking position by the follower m<1>.

Title: Process for the production of alcohols
IPC: C07C29/141
Filed: 1951-07-23
Abstract: Alcohols are obtained from acetals or semiacetals by treating with hydrogen and water in the presence of a hydrogenation catalyst at an elevated temperature and pressure.  Starting materials are acetals of formula <FORM:0708742/IV (b)/1> and semi-acetals of formula <FORM:0708742/IV (b)/2> in which R1 is hydrogen and R2 and R3 are aliphatic hydrocarbon radicals.  Suitable catalysts are, for example, a mixture of nickel, magnesium oxide and kieselguhr, a mixture of cobalt, thorium oxide, magnesium oxide and kieselguhr, and Raney nickel.  The preferred temperature range is 100-220 DEG  C. and the pressure should be above 10 kg. per cm.2.  Hydrogen or a mixture of hydrogen with inert gases such as nitrogen and methane may be used as the hydrogenating gas.  The process is particularly suitable for obtaining pure alcohols from synthetic mixtures which contain alcohols and aldehydes in addition to hydrocarbons.  Additional alcohols or aldehydes may be added to the mixture if required if the original ratio of aldehyde to alcohol does not correspond to the ratio needed for the formation of acetals.  In the examples (a) AC30 acetal is obtained by heating a mixture of C10 alcohol and C10 aldehyde with hydrochloric acid and benzene.  The acetal is mixed with water and a nickel-magnesia-kieselguhr catalyst and treated with hydrogen at elevated temperature and pressure to give a C10 alcohol; (b) a C7 aldehyde is produced, using a cobalt catalyst, by the addition of water-gas to a hydrocarbon fraction containing C6-olefinic hydrocarbons and is mixed with a C6 alcohol, a small amount of oxalic acid is added and the mixture heated; the semiacetal found is mixed with water and a reduced nickel-magnesia-kieselguhr catalyst and heated with hydrogen at elevated temperature and pressure to give a C7 alcohol; (c) a product of the catalytic hydrogenation of carbon monoxide is heated with a caustic soda; the product is treated with water-gas in the presence of cobalt sulphate to give a mixture containing acetals and semi-acetals, the mixture is treated with water and hydrogen in the presence of a nickel-magnesia-kieselguhr catalyst at elevated temperature and pressure to give a mixture of alcohols.

Abstract: 1,089,385. Semi-conductor devices. WESTINGHOUSE ELECTRIC CORPORATION. April 22, 1966 [May 3, 1965], No. 17636/66. Heading H1K. In a PN junction rectifier in which the junction extends over the entire area of the semiconductor wafer parallel to its major faces and emerges at the peripheral edge a depression with a rounded bottom is formed in one face to less than the junction depth to divide the face into a major island portion and a minor peripheral portion. The island may be further subdivided into sectors of the same or different sizes by additional grooves of the same depth or less. An electrode is provided on the island or on each sector to form one or more diodes with a common second electrode on the opposite wafer face. If the base of the depression extends into the junction depletion layer surface breakdown is prevented. Additional control over the width of the depletion layer at the periphery may be provided by an electrode on the peripheral portion. A typical device is made by first oxidizing the surface of a 100 ohm. cm. N- type silicon wafer, etching the oxide from one face and diffusing gaseous aluminium into it. After removing the oxide the wafer is sandwiched between molybdenum contacts with intervening foils of aluminium silicon eutectic and gold-antimony alloy at the P and N faces respectively and the assembly integrated by heat. The depression is then formed by ultra sonic cavitation followed by etching or by etching alone. In other devices tungsten or tantalum contacts are attached to the wafer using lead, silver, or gold-based solder, though sputtered or vapour deposited contacts may also be used.

Title: Improvements in or relating to liquid dispensing systems
IPC: G01F11/04
Filed: 1958-06-03
Abstract: 854,456. Delivering measured quantities of liquids. CLEMENTS, C. A. June 3, 1958 [June 4, 1957], No. 17728/58. Class 106(5) [Also in Group XXIX] A liquid dispenser, particularly for beer, comprises a pair of cylinders 14 having pistons 20 linked by ball-ended rods 19 to a second pair of pistons 8 interconnected by a closed hydraulic circuit, a control valve 23 by which beer from a pressurized source 1 can be directed to one or other cylinder 14 to force out the contents of a cylinder through an outlet 26, and an expansion chamber 65 connected to the lower air spaces 18 of the cylinders 14 to act as a cooling system on each operation of the dispenser. During initial assembly of the dispenser, the pistons 8 are withdrawn into their cylinders 38 and the spaces 42 are completely filled with hydraulic fluid and then one rod 19 is pushed in to expel air and fluid from a bleed valve 17 until the rod has reached a position giving the required stroke of the piston 20 for the measured quantity desired. To prevent the beer foaming in warm weather, the speed of delivery may be reduced by adjusting a needle valve 16 in the hydraulic circuit. The control valve plug 52 has two passages 53, 54, the delivery passage 54 being of greater cross-section and arranged to connect the filled cylinder to atmosphere at the outlet before the passage 53 connects the other cylinder to the pressurized source 1. Counting means may be connected to the valve 23 and a bleed valve 24 is provided in front of it. In their uppermost positions, the pistons 20 seal against bosses 29 and these bosses are slightly off-centre in order to move the pistons slightly and allow them to centre themselves. The air spaces 18 are connected to the expansion chamber 65 by pipes 64 and to atmosphere by drain cocks 60 and non-return pressure relief valves 15A. As one piston descends, the compressed air in the space 18, containing beer evaporated from the walls of the cylinder 14, expands in the chamber 65 and gives off heat through a conductive cover 69 and then is sucked into the other space 18 as the latter expands. Alcohol, or other refrigerant may be added to the chamber 65 through a plug 62. A spring- loaded valve 66, for relieving excessive vacuum or for draining, is fitted to the chamber 65. An enclosing and insulating cover 10 is provided.

Abstract: 1487114 Optical scanning system RECOGNITION EQUIPMENT Inc 29 April 1975 [15 Aug 1974] 17772/75 Heading G4R Characters in spaced lines, e.g. an address on an envelope are scanned, a digitized signal is produced and stored and data from a selected line of the characters is read from the store. An image of a moving data carrying document is formed on a photodiode array 30 which may contain a line of 512 photodiodes. Data from the array is fed to an A/D converter 44 which forms a stream of four bit words representing the output values of the photodiodes. These signals feed a correlator 48 which produces a series of binary signals each bit of which corresponds to the output of a respectively photodiode. The bits are fed serially to a memory 52 containing a plurality of shift registers. The document is scanned in strips with data from each strip being fed into the memory. A line top/bottom detector 54 is used to detect the presence of a predetermined line of print, e.g. the lowest line and determines where the top and bottom of this line is. This detector is used to determine skew and to enable read out of the lowest line. The memory 52 may store all the data from the photocells or may act as a buffer holding sufficient scans to allow the lowest line to be detected. For instance higher lines may extend further than the lower lines and so be detected as the lowest line before the true lowest line is scanned (Figs. 5C, 5D, not shown). When the lowest line is read out it may be corrected for skew and normalized for height.
