Abstract: 1,248,507. Carbon articles by slurry casting. KUREHA KAGAKU KOGYO K.K. 31 Jan., 1969 [31 Jan., 1968], No. 5316/69. Heading C1A. [Also in Division C5] Shaped carbon articles are produced by (a) preparing a slurry containing as the major or only carbonaceous starting material a modified pitch having a softening point above 170‹ C.; (b) forming the article by slurry casting; (c) drying; and (d) carbonizing in an inert gas. The article may be heated in an oxidizing atmosphere between steps (c) and (d) and/or graphitized after carbonization. The modified pitch is produced from coal-tar pitches, petroleum asphalts and other pitch-like substances, e.g. by-products of cracking petroleum, by heat-treating, i.e. dry distillation, extracting by solvent, or treatment with ozone, oxygen, air, oxides of nitrogen, halogens, sulphur or sulphur compounds.

Abstract: 1,046,322. Firearms. SOC. ANON. STAR, BONIFACIO ECHEVERRIA. Feb. 7, 1964 [April 25, 1963; Aug. 9, 1963 (2)], No. 5327/64. Heading F3C. , The breech block 11 is provided with a safety lever 22 which can engage in a slot 5v in the body portion 5 of the gun and a rocker 23 both pivotally mounted on a pin 21. A rod 27 projects slightly from the front of the breech block so as to strike the end of the barrel 6 when the breech block has completed its forward movement. The rod 27 is forced backwards causing the rocker 23 to pivot and force a firing pin 26 forwards to fire a cartridge, the lever 22 also being pivoted about pin 21 by the rocker 23 and remaining clear of the slot 5v due to the inertia of the lever 22 for a sufficient time to permit the breech block to recoil. If there is a defective cartridge or no cartridge in the breech when the breech block is forced forwards the lever 22 engages in the slot 5v to prevent the breech block moving back. The gun may then be cocked by forcing backwards spring-loaded rod 30, Fig. 5 (not shown), which is slidably mounted in the rear widened portion of the barrel and is provided with a sleeve 31 located in a slot 5f in the gun and having a handle 32. The rod 30 contacts the rod 27 which is forced backwards to free the lever from the slot 5v and then the breech block may be forced backwards. The cocking handle may be rigidly fixed to the sleeve 31 or pivotally mounted thereon.

Title: Direct-current converter
IPC: H02M3/338
Filed: 1972-02-04
Abstract: 1376078 Starting inverter oscillators PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 4 Feb 1972 [9 Feb 1971] 5358/72 Heading H3T [Also in Division H2] In a D.C.-D.C. converter of the type in which the output of an oscillator having a transformer TR is rectified at D1 to provide the required D.C. output at B1, B2, a saturable choke S2 is included between the transformer and smoothing capacitor C, the choke having a further winding S3 connected between the smoothing capacitor C and the output B1. The winding S2 of the saturable choke prevents starting difficulties for the oscillator due to the charging current of the smoothing capacitor C When capacitor C is fully charged, however, the choke would be unsaturated at the beginning of the first half cycle, giving a reactive loss. The additional winding S3 is thus included so that the load current maintains the choke saturated during the whole of the operating period. In Fig. 2 (not shown) a single secondary winding is coupled to a bridge rectifier and the choke only has two windings.

Abstract: 329,665. Sokal, S. Feb. 20, 1929. Double hinges; attaching h i n g e members to articles adjustably. - In an expanding suitcase &c. having telescopic hinges and hasp fastenings arranged on the exterior thereof, each hinge or fastening comprises two telescoping members, an automatic clutching or fixing device for automatically fixing the two members a g a i n s t outward movement, means for throwing said device out of action and means for throwing it into action, the last means being operable by the relative longitudinal movement of the two telescoping members; the automatic clutching or fixing device may be thrown out of action by a manually-operated device for locking the two telescoping members in an adjusted position. As shown the pawl 9 of the automatic clutching or fixing device is loosely mounted on the shaft 6 in the outer telescoping member 1 and is normally forced into engagement with the rack 4 on the inner member 2 by a spring 14. The manually-operated locking device 7 is fixed to the shaft 6 which carries a projection 18 cooperating with a projection 19 on the spring pawl 9 and the device 7 carries a pin 8 which can be pushed through an aperture 17 in the member 1 to engage one of a series of apertures 3 in the inner member. When the pin 8 is removed from the apertures 3, 17 to change the capacity of the case, the shaft 6 and projection 18 are turned and, after a certain movement during which the unlocking of the device 7 does not affect the spring pawl, the projection 18 engages the projection 19 and moves the pawl 9 away from the rack; the projection 18 is then caught by a spring catch 11 and both the parts 7, 9 are locked with the pawl 9 out of engagement with the rack 4 so that the case can be extended and a lateral projection 15 on the pawl encounters a cam 16 on the inner member and moves the pawl further away from the rack when a projection 10 on the pawl trips the catch 11 and allows a spring 13 to move the projection 18 past it. The case is then adjusted downwards when the cam 16 releases the projection 15 and allows the spring 14 to move the pawl into engagement with the rack and the device 7 towards the outer member 1; when the case is adjusted, the pin 18 is pushed home in the apertures 3, 17. The catch 11 may be tripped by the cam 16 through an intermediate device and the device 7 may have lateral resilient lugs which engage the sides of the member 1 in the locking position and prevent accidental locking during the adjustment of the case.

Abstract: 820,904. Valves. GENERAL GAS LIGHT CO. Feb. 25, 1957 [March 12, 1956], No. 6217/57. Class 135. In a valve comprising a housing having at least one valve chamber across which extends a flexible diaphragm formed with a valve member sealingly engageable with a seat at the end of a passage extending from the chamber to control communication between a port connected to the passage and a port connected to the chamber, the diaphragm has openings therethrough whereby fluid pressure within the chamber acts on both sides of the diaphragm and is flexed by actuating means movable axially of the passage. As shown, the valve comprises a housing 2, Fig. 1, having first, second and third ports 14, 17, 16, Fig. 2, communicating respectively with valve chambers 4, 9 and an interconnecting passage 21 formed at its ends with valve seats 34, 32 engageable with bosses 27, 33 of diaphragms 6, 11 stretched across the chambers 4, 9 and interconnected by a rod 37. The rod 37 is formed with an enlarged head 43 providing a shoulder 47 against which pressure fluid passing through holes in the diaphragm 11 may act. The head 43 has a pin-and-slot connection 54, 56 with a spring-loaded button 51 which may be operated by a hand lever 52, pedal, electrically or by fluid pressure. With port 14 an inlet, port 17 an exhaust and port 16 connected to apparatus to be operated and the lever 52 in its operative position shown pressure fluid passes from the port 14 through the port 16 to the apparatus. On rotation of the lever 52 so that its tip 58 is disengaged from the button 51, pressure fluid passing through holes 26 in the left-hand diaphragm 6 acts on the larger left side thereo to seat the boss 27 and unseat the boss 33 so that the apparatus is connected to exhaust. With port 17 an inlet, port 14 an exhaust and port 16 as before, connected to the apparatus and the lever 52 in its operative position, the apparatus is connected to exhaust. On release of the lever the pressure fluid passing through the holes in the diaphragm 11 acts on the shoulder 47 to unseat the boss 33 and seat the boss 27 so that the apparatus is connected to the supply of pressure fluid. In another embodiment, a housing 70, Fig. 4, having an inlet port 17 and an outlet port 16 is closed by a cover 73a which clamps a diaphragm 78 having a boss 76 against the housing. Pressure fluid from the inlet 17 passing through holes in the diaphragm 78 acts on the surface 81 to hold the boss 76 on its seat 79. A step 82 on the actuating rod 80 may be formed to assist in holding the valve closed. This step 82 coacts with a recess 83 in the cover 73a when the valve is open to reduce the area subjected to pressure.
Patent GB-495163-A (GB)
Title: Improvements in extraction of waste aqueous liquids containing phenols
IPC: C02F1/26
Filed: 1938-02-28
Abstract: A diaryl ether of the benzene series or a mixture containing the diaryl ether is used to extract phenols from waste aqueous liquors. Diphenyl ether is preferably employed, being passed through an extraction plant filled with the waste liquor or through which the waste liquor flows continuously.  The phenol is recovered from the diphenyl ether by extraction with an alkaline liquid.  Advantageously a substance is added to the diphenyl ether which lowers its melting point, e.g. a phenyl ether of a hydroxydiaryl of the benzene series, e.g. the phenyl ether of a hydroxydiphenyl.  Commercial diphenyl ether containing 10-20 per cent of these phenyl ethers may be used. In an example waste aqueous liquor containing 12,9 grams/litre of phenol and 150 grams of common salt/litre is shaken six times with diphenyl ether (50 ccs./litre for each extraction).  The phenol content of the liquor is reduced to 1,1 grams/litre.

Abstract: 564,865. Dynamo-electric machines. HITCHCOCK, S. I. April 21, 1943, No. 6370. [Class 35] A permanent magnet motor or generator has permanent magnet 15, Fig. 2, provided with a leakage path comprising a number of magnetic portions 16 separated by material 18 of high reluctance. This leakage path extends between laminated polepieces 19. In the motor shown, the permanent magnet forms the rotor and the stator poles 2 are similarly provided with leakage paths 24, 25. Exciting coils 4 surround each pole and these are switched off, or reversed, by a cam-operated switch surrounding one end of the rotor shaft 10. The position of the switch relative to the cam can be altered by the handle 11a for adjustment of the speed and direction of rotation. The cam mechanism is generally of the same kind as that shown in Specification 547,668. Fig. 3 shows a section of the form shown in Fig. 1. In a modification, the permanent magnet may be surrounded by cast material and such material may also be deposited on the inside of the magnet. In a further modification, the permanent magnet is replaced by a soft iron core excited by an axial solenoid. To improve the attraction between the rotor poles and the stator poles when the poles are approaching the leakage, elements may be inclined with r.espect to the axis so that while the poles are approaching the attracting force is great, but as soon as the poles are separating the restraining force falls to a minimum. Specifications 13886/15, [Class 35], and 545,583 also are referred to.
