Abstract: 765,933. Pulse circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. Oct. 22, 1952 [Oct. 31, 1951], No. 10728/56. Divided out of 765,932. Class 40(6) Fig. 1 shows the combination of two AND " gates 30, 31, with an " OR " gate 42 comprising gas-filled diodes 32, 33, 34, 35 and 40, 41 respectively, the whole comprising a coincidence circuit in which the voltage at the output terminal 45 follows. the input voltages applied to input terminals 36-39. Normally tubes 34, 35 areconducting and if a positive pulse is applied to one only of the inputs 38, 39 to cut-off the corresponding tube there is no appreciable voltage change at the commoned anodes; if however two inputs are applied then an output voltage is applied to tube 41. Similarly the " AND " gate 30 applies a voltageto tube 40 only in thepresence of inputs at both 36 and 37 the- " OR gate 42 passing a voltage to the output 45 when coincidence occurs in either of the circuits 30 or 31: Thus one tube of each group of tubes 34, 35, 41 or 32, 33, 40 is always discharging at any given instant. Fig. 2 shows a modification comprising two glow transfer discharge tubes: 50, 55 the cathode 54 and anodes 51, 52 and the cathode 59 and anodes 56, 57 each function as an " OR " circuit and the remaining anode and the cathode in each tube function together as an "AND" circuit. In the stand-by condition a glow discharge exists between electrodes 53-54 and 58-59 respectively if a positive input is applied to input 65 or 66 or to input 67 or 68 the voltage at output 60 similarly increases as the voltage drops across the tubes are substantially independent of the current flow through them and the voltage at the the cathode has been increased. In a further modification shown in Fig. 3 the tube 70 operates as an electronic switch or " OR " circuit. Tubes 71, 72 are normally conductive and both discharge paths in tube 70 are normally cut-off. When the anode voltage of either tube 71, 72 is increased' the corresponding discharge path in tube 70 fires and an output is derived from across the cathode load to render tube 75 conductive. Two " OR " circuits of typeshown in Fig. 3 may be combined to provide a four input " OR " circuit.

Title: Apparatus for reading video- and/or audio signals by optical means
IPC: G11B7/12
Filed: 1972-03-08
Abstract: 1391335 Optical playback apparatus PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 8 March 1972 [11 March 1971] 10792/72 Heading G5R [Also in Divisions G1 and G3] In apparatus for the optical playback of a disc record 1 having spiral or concentric video and/or audio tracks, axial and/or radial shifts in the illuminated tracks are detected by forming an image thereof, which image resembles a linear grating, upon one or more gratings 11, 12 of the same periodicity as the image, behind each of which is a radiation detector (not shown). In the arrangement shown, axial displacement of the tracks moves the image thereof away from the transducing detector 10 towards one of gratings 11, 12, thereby increasing the output of the detector associated with that grating. The difference in detector outputs may thus be used to control the image lens 8 to return the displaced image. Alternatively, a single grating (C), Fig. 11 (not shown), may be placed in the plane of the transducing detector, so that the outputs from detectors associated with the grating (C) change as the magnification of the tracks changes. In a further embodiment, Fig. 6 (not shown), radial displacements of the tracks move the image thereof laterally across a grating (36). The output from an associated detector (not shown) thus changes and may be used to displace the read beam radially. The sign of the displacement may also be detected by constructing the grating (36) in two parts (36a, 36b), Figs. 7, 9, 10 (not shown), which are not spatially in phase. An arrangement of three gratings (11), (12), (36), Fig. 12 (not shown), may be used to detect both axial and radial dispacements. To compensate spatial variations across the beams, the beams may be split, Figs. 5a, 5b (not shown), possibly into differently polarized or coloured beams, Figs. 8a, 8b (not shown), to provide reference beams. Each grating and associated detector may be constituted by a detector in the form of alternate radiation sensitive/insensitive stripes, Fig. 9 (not shown).

Title: Improvements in apparatus for applying crown corks or like closure members to filledbottles or other receptacles
IPC: B67B3/02
Filed: 1940-06-28
Abstract: 537,674. Closures for bottles. LIQUID CARBONIC CO., Lid. (Liquid Carbonic Corporation.). June 28, 1940, No. 11006. [Classes 125 (ii) and 125 (iii)] In the process of applying a crown cork or other sealed closure to a bottle or like receptacle, the neck of the bottle is enclosed within an hermetically sealed chamber prior to the final sealing which takes place in the chamber; the air can be exhausted from the chamber prior to the final sealing. A hollow centre post 1 carries the rotating parts of the machine and also supports the stationary housing 2 which surrounds the upper part of the crowning heads. The bottles are fed from the table 4 to the rotating support 5 and are carried round by the fingers of a pair of vertically spaced star wheels 11 to positions beneath crowning heads 10. Each of these heads has a cylindrical housing 12, Fig. 7, with a roller 14 at its top end working in a stationary cam track 15. The crowning throat 25 is carried by a hollow cylinder 16 biassed downwardly by the spring 17, and having within it a plunger 21 pressed downwards by the spring 22. The upper end of the plunger has a reduced neck 23 and a wedge shaped head 24 normally fitting between pivoted dogs 18 which spread into the notch 19 thereby locking the parts 21, 16, 12 so that they all move down together. When the lower end of the plunger 21 reaches the crown cork on the mouth of a bottle, the plunger will stop while the cylinder 16 continues to descend until the wedge 21 leaves the dogs 18 so that the housing 12 continues to descend while the cylinder 16 stops. The crowning throat 25 on this cylinder has a crown crimper 26, and a sealing washer 27 gripped between a flange 28 and a ring 29; the upturned portion 30 of this washer is held in sealing engagement with the plunger by a clamping ring so that the upper end of the throat is hermetically sealed. The lower end of the throat has an annular projecting portion 32 surrounded by a rubber sealing ring 33. The crowning cap is carried on a support which contains a rubber ring 38 of U-shape in cross section and kept in its normal position, shown in Fig. 4, by the action of springs 36, but which can be compressed vertically by the depression of the ring 35 during the capping operation so that it expands horizontally to grip the bottle neck and seal the joint. The rings 30, 33, 38 thus hermetically seal a chamber within which the crown cork is applied. Just before the crown cap is applied the chamber is exhausted by an air pump attached to the pipe 49.

Patent GB-799919-A (GB)
Title: Improvements in or relating to phenthiazine derivatives
Filed: 1957-04-04
Abstract: The invention comprises 3-methane sulphonyl phenthiazine which may be prepared, according to one method, by heating 3-methane sulphonyl diphenylamine with sulphur, yielding a mixture of the 1- and 3-methane sulphonyl phenthiazine isomers which may be separated for example by absorption in alkaline alumina followed by elution with a benzene solution of ethyl acetate.  This method is preferably effected in the presence of a small amount of iodine as catalyst, at about 150-250 DEG  C. and in an atmosphere of nitrogen.  Another method which yields only the 3-methane sulphonyl isomer comprises cyclization of a diphenyl sulphide of the formula <FORM:0799919/IV (b)/1> in which one X represents a methane sulphonyl group and the other a hydrogen atom, in an anhydrous solvent at elevated temperature in the presence of an acid-binding agent.  The solvent may be a tertiary amine, e.g. dimethyl aniline or an N-substituted amide of a fatty acid having not more than 3 carbon atoms, e.g. dimethyl formamide or N-methyl acetamide.  Suitable acid-binding agents are sodium hydroxide and sodium or potassium carbonate; dehydrohalogenation catalysts such as copper powder may sometimes be used.  The 3-methane sulphonyl phenthiazine may be used in the synthesis of N-amino alkyl-phenthiazines.  In examples: (1) 3-methane sulphonyl diphenylamine, sulphur and some iodine are heated from 130 DEG  to 235 DEG  C. until evolution of H2S ceases; the mixture is then extracted with benzene at 60 DEG  C. and the benzene solution is passed through a column of alumina which is thereafter eluted with benzene containing 10 per cent of ethyl acetate to remove 1-methane sulphonyl phenthiazine and with benzene containing 25 per cent ethyl acetate to remove 3-methane sulphonyl phenthiazine; (2) a dimethyl formamide solution of 2-bromo-21-amino-41-methane sulphonyl diphenyl sulphide is boiled in the presence of K2CO3 and copper powder and then the mixture is stripped of solvent and poured into water; the crude 3-methane sulphonyl phenthiazine so isolated may be purified by absorption from alkaline alumina and elution of the absorber material with benzene containing ethyl acetate. 3-Methane sulphonyl diphenylamine is prepared by decarboxylating 2-carboxy-3-methane sulphonyl diphenylamine, obtained by condensing 3-methane sulphonyl aniline with 2-chlorbenzoic acid. 2 - Bromo - 21 - amino - 41 - methane sulphonyl diphenyl sulphide is prepared by reducing with iron and acetic acid the corresponding 21-nitro compound, itself obtained by decomposition in the presence of cuprous bromide of the diazonium salt of 2-amino - 21 - nitro - 41 - methane sulphonyl diphenyl sulphide, prepared by condensing 2-amino thiophenol with 3-nitro-4-chlorophenylmethylsulphone, which is obtained by nitration and oxidation of 4-chlorothioanisole.
