Title: Electric circuit controller
IPC: H01H35/32
Filed: 1946-07-27
Abstract: 614,985. Switches held and set free mechanically. DEHN, S. G. (Minneapolis-Moline Power Implement Co.). July 27, 1946, No. 22438. [Class 38 (v)] A switch suitable for controlling the ignition circuit of internal-combustion engines, which may be tripped by either of two separately variable conditions such as failure of oil pressure or excess temperature, or be operated manually, comprises a control rod 25 slidably carrying a spring-biassed tubular contact-member 58, which is released by L-shaped trigger members 32, 33 under the influence of pressure and temperature bellows 17, 18 to engage a fixed contact 27. The control rod is guided by a bush 24, extending through the front of the casing, and normally located in a floating position' by a pin 69 extending between two blade springs 64, 65. The contact member 8 has a tapered flange forming a radial catch surface 61, which will just pass through slots 41, 47 in the trigger members, and is urged towards the fixed contact 27 by spring 63. The end of contact 58 is recessed to receive a contact button 26 on the control rod. The trigger arms 32, 33 are pivoted on a common pin 34 so that the arm 32 lies within the channel part of the arm 33. A blade spring 56 held by the lock-nut on the setting screw 54, together with the upturned portion 57 on the arm 32 holds both trigger members together as a unit, but allows the arm 33 a limited clockwise movement independently of the arm 32. In the starting position, Fig. 6, the control rod is pulled so that the button 26 carries contact 58 with it and the inclined surface of the catch 61 forces its way through the slots 41, 47 in the trigger members against the action of bladespring 51, and is held by the arm 40. As the oil pressure builds up, bellows 18 rocks the arm 32 so as to release the catch 61 which passes through the opening 41, but is arrested by the trigger arm 46, which is normally held by spring 56 slightly to the right of arm 40, Fig. 8. Thereafter, clockwise rotation of arm 33 due to excess temperature or failure of oil pressure releases the contact 58, which is urged by spring 63 to engage fixed contact 27. The motor may also be stopped at any time by depressing the control-knob so that the button 26 engages the contact 27.

Title: A method of and apparatus when used for the separation of grain
IPC: B07B4/04
Filed: 1962-06-14
Abstract: 1,014,723. Pneumatic separating. ALPINE A.G. MASCHINENFABRIK UND EISENGIESSEREI. June 14, 1962 [June 15, 1961], No. 22819/62. Heading B2H. Pneumatic separation takes place in an upward current of air within a column, of the form shown in Fig. 1, which has oppositely inclined sections providing a zig-zag course. Material, preferably grain, falling within the column against the upward flow of air may strike the side walls of the sections which in this respect provide a cascade of steeply angled shoots. Those faces of a section acting as a shoot have bevelled corners to feed material towards the centre of the column. The column may be hammered or vibrated to encourage precipitation. The cross-section of the column may diminish with height. As shown in Fig. 4, grain A with air L is fed to a cyclone 7 from which the grain is passed to a valve 8 for admission to a separating column, shown symbolically as a zig-zag line, while the air L is passed to the bottom of the column. The fines F are taken off the top of the column with the air L while the offal is extracted through a valve 9 at the bottom. A number of such columns may be set up in chain so as to extract particles of 0-200Á from the top of the first column, those of 200-400Á from the top of the second column, and those of 400-600Á from the top of the third column, the coarse material from the bottom of each column being fed to the next column. By feeding the fines from the top of one column to the next column a successive refinement is produced wtih the coarse material taken from the bottom of each column decreasing in size as the material progresses along the chain (see Figs. 6 and 7, not shown). Separating columns according to the invention may be arranged in parallel as shown in Fig. 8 where they are fed by vertical uplift from a beater mill 18, 19. Such a parallel array of separating columns may be fed with material transported on a filter cloth 23 in a duct as shown in Figs. 9 and 10. Air jets 24, which may alternate between left and right of the duct sweep the material into the columns. Such an array may alternatively be fed as shown in Fig. 11.

Filed: 1971-04-19
Abstract: 1322444 Methacrolein JAPANESE GEON CO Ltd 19 April 1971 [4 March 1970] 23115/71 Heading C2C Methacrolein is separated from a gaseous mixture containing it by dissolving it in an organic liquid which is miscible with both methacrolein and water, separating the solution of methacrolein in the. organic liquid from the gaseous mixture and extracting organic liquid from the solution using water as an extracting agent to leave a methacrolein-rich extraction residue. Suitable organic liquids include methanol, ethanol, isopropanol, n-propanol, acetone and acetonitrile. Preferably the concentration of methacrolein in solution in the organic liquid is made up to at least 40% by wt. by adding additional methacrolein. When the aqueous extract containing organic liquid also contains some methacrolein, this may be distilled off if the organic liquid is one which in the presence of water is less volatile than methacrolein, e.g. acetone or methanol; the methacrolein distilled off may be recycled to make up the concentration in the organic liquid referred to above. The gaseous mixture containing acrolein may be derived from the oxidation of isobutylene or may be gas containing unreacted methacrolein from the oxidation of methacrolein to methacrylic acid.

Title: Improvements in soap and soap powders
IPC: C11D9/14
Filed: 1946-08-02
Abstract: Soap is made from castor oil, with or without other fatty oils, saponified in the presence of trisodium phosphate.  The latter may be added after the saponification is initiated with caustic soda or other usual saponifying agent.  Sodium chloride may additionally be added to render the soap mass more fluid.  The additional fatty oils specified comprise copra oil, and a mixture of shea nut oil and palm nut oil.  Examples of soaps having the above compositions are given including the preferred proportions of the respective ingredients. The soaps may be moulded or easily reduced to powder.  A detergent powder is exemplified comprising a mixture of powdered soap made from castor oil alone in the presence of trisodium phosphate and sodium chloride, together with a large bulk of trisodium phosphate.  Any excess alkali in the saponification is neutralised by addition of further fatty oil or inversely, any excess of fatty oil by the addition of further alkali.

Title: Improvements in and relating to a Low Pressure Fruit Press, particularly for Oil Palm Fruits
IPC: B30B9/18
Filed: 1967-05-18
Abstract: 1,170,315. Fruit press. STORK & CO's APPARATENFABRIEK N.V. GEB. 18 May, 1967 [2 March, 1967], No. 23146/67. Heading B1D. A fruit press comprises a press cylinder with a fixed inlet section 35 and an axially movable discharge section 45, whose position relative to solids discharge cone 40 is regulated to maintain constant pressing conditions. Regulation could be manual, but in Fig. 2 section 45 is moved by a hydraulic or pneumatic jack 46-53 of annular form against a spring 55. Screw 43 is rotated by electric motor 42, and increasing friction between press cake and section 45 causes section 45 to turn against a further spring (61) (Figs. 3A to C, not shown). Flange 46 carries an obtusely extending cam guide (56), and the turning of the guide operates a valve (59), which then delivers fluid to the jack and moves section 45 leftwards, widening outlet 73 and reducing the area on which friction acts. As guide (56) moves leftwards, it restores valve (59) to the closed position. Valve (59) is double ended, and subsequent return rotation of section 45 as friction lessens releases pressure from the jack to restore status quo. In Fig. 1 (not shown) the screw is replaced by a reciprocating plunger (2) and the discharge section (13) is imperforate and movable only axially. An annular jack effecting this movement against spring(s) is connected in parallel with the jack which advances plunger (2), and section (13) is moved to widen the discharge opening if the cake resistance causes the pressure in the jack supply line to rise sufficiently to overcome the spring(s).

Abstract: 231,515. T÷nsmann, H. March 28, 1924, [Convention date]. Voucher-issuing.-The record material feeding means of a cash register is rendered operative by the depression of a special transaction key or by the actuation of an independent key during a single or indefinite number of operations respectively. The transaction key depressed is raised automatically at the end of each operation, whereas the independent key is retained in the depressed position until released by a manipulative means. As shown in Fig. 1, a pitman 47 controls the feeding rollers 77, 78 through an arm 79 that is connected thereto and to a rod 80 carrying an eccentric bearing 81 for the roller 77, the roller being moved clockwise to engage the flange 82 with the record material. The pitman 47 has slidablv mounted thereon a pair of spring- controlled plates 46, 58. The plate 46 has a curved edge 45 which co-operates with a projection on the stem of each of the transaction keys 22 and is provided with a notch 54 moved into alignment with a notch 72 in the pitman when one of the keys 22 is depressed. The plate 58 is provided with a roller 64 and has pivoted thereto a pawl 56 having a pin 59 that normally engages a shoulder 60 of a lever 61. The lever 61 is operated from the driving shaft 20 by a cam 73 and during the clockwise movement thereof permits the pawl 56 to fall into the notches 54, 72 whereupon the further movement of the lever, through engagement between the surface 63 thereof and the roller 64, causes the rearward movement of the plate 58 and of the pitman 47. The keys 22 co-operate with a detent plate 25 which is adapted to maintain the operated key in the depressed position, release thereof being effected by a movement of the detent plate that is produced by the engagement of a pin 31 on the plate with a surface 32 on a guided pitman 33 adapted to be reciprocated by means connected with the main driving gear, a cam 37 rotated thereby and a pin 38 on the pitman. An independent key 86 when depressed is adapted to permit operation of the feeding means for an indefinite number of operations. The key 86 is supported by studs 87 and has a projecting lug 88 adapted to engage the plate 46 and to move it to the same extent as the keys 22. A pawl 51 under the control of a spring 50 attached thereto and connected to the plate 46 engages one or other of a pair of notches 90, 91 in the key stem to hold the key in its raised or depressed position. The key 86 is released by a manually operated release key 92 adapted to engage the pawl 51 and free it from the notch 91 whereupon the spring 50 returns the plate 46 and key 86 to their normal position.
