Title: Improvements in electric relays suitable for railway signalling systems
IPC: H01H51/22
Filed: 1920-06-01
Abstract: 167,632. Leake, R. C. June 1, 1920. Electromagnetic and magnetic switches; polarized relays.-Relates to direct-current polarized relays of the tractive type, suitable for railway signalling systems, in which three different and distinctive indications are required according, say, as the switch points in an interlocking system are in the normal, and reverse positions, or in some intermediate position. As shown diagrammatically in Fig. 4, two pairs of coils D. E each control a neutral armature 12, 12<1> pivoting about a lug 13 and carrying contact-making members 14, 14<1>. A polarized magnet P, shown separately in Fig. 3, is pivoted between the coils so as to swing about a vertical axis 19, and carries a contactmaking member 27 and a counterbalance weight 36. If the current through the coil D is in the direction that makes the pole-piece 4 a north pole, as indicated by N, Fig. 3, the polarized magnet P will be swung so as to move the arm 27 to the right, making contact as shown in Fig. 4. If the current through the coil D is then reversed, the arm 27 will be swung to the left. A similar action occurs when the coil E is energized and a reversal of current takes place. With the switch S in the neutral position, as shown in Fig. 4, all current from the battery K is cut off from the coils D, E, wherefore the armatures 12, 12<1> and contact members 14, 14<1> are both at the dropped or lower position. When the switch S is moved over to the left, the coil E is energized and the contact 14' only is raised. If the. switch is now moved to the right, the armature 12<1> drops, the polarity of the coils E is changed, and the polarized armature P is rocked so as to move the contact 26 over to the left, before the armature 12<1> can pick up again; this movement of the contact 26 energizes the coil D so that the armature 12 is attracted and the contact 14 only is raised. The three distinct positions of the switch therefore correspond to (a) no current, (b) steady current in one direction, and (c) a reversal of this current.

Title: A pressure-limiting arrangement for pumps and compressors
IPC: F04D15/00
Filed: 1952-06-13
Abstract: 724,014. Reciprocating pumps and compressors. TECALEMIT, Ltd. June 13, 1952. [July 30, 1951] No. 15002/52. Classes 8 (1) and 102 (1). [Also in Group XXIX] A pump or compressor P delivering fluid from a suction duct 1 into a pressure storage tank 32 has a pressure limiting device comprising an enclosed space 13 separated by a movable partition 10, such as a piston into an upper chamber, communicating freely with an outlet 36 leading the fluid to a point of use, and a lower chamber communicating with the pump delivery duct 30 and with the tank, the two chambers communicating with each other through a passage controlled by a throttle valve 9 which produces a pressure difference between the two chambers, and a relief valve 6 in the pump delivery duct is mechanically connected by a valve rod 5 to the movable partition so as to be held on its seat by the differential pressure acting on the movable partition when fluid is being delivered freely through the outlet 36. Fluid delivered by the pump passes through a spring-loaded valve 21 and passage 33 into the tank where, in the case of liquid being pumped, it is retained under air pressure. The fluid pressure also raises the piston 10 against its loading spring 18 and thus opens the valve 9 for the fluid to pass to the outlet 36. When the flow at the outlet is reduced or stopped, the higher pressure acting on top of the piston causes it to be lowered thus reducing the closing pressure on the relief valve 6 which consequently opens to by-pass the pump output through the suction pipe 3. Simultaneously the pressure in the tank causes the valve 21 to close thus retaining the pressure on the upstream side of this valve. The valve rod 5 is extended to form a piston 28 which is subjected to atmospheric pressure through a port 26 to reduce the upward force created by the piston 10 on the relief valve.

Title: Improvements in or relating to plate-rolling mills
IPC: B21B39/10
Filed: 1920-06-07
Abstract: 168,170. Davy Bros., Ltd., and Hand, T. W. June 7, 1920. Rolling; roller tables.-In a plate-rolling mill, the work is centred on the roller table by one or more pairs of arms passing between adjacent feed-rollers and rocked symmetrically towards or from each other on axes parallel to the direction of feed. The rolling-mill may be of the threehigh type, tables on each side of the rolls being pivoted in pairs of stationary cradles so as to permit the inner ends to be raised or lowered, the feed-rollers being driven in the required directions by gearing from a motor. In order to centre the plate laterally before passing through the rolls, a number of pairs of arms 27, 28 are provided which are pivoted at intervals apart in the length of the feed-table on longitudinal shafts 22, 23 and are connected together by links 26 and bell-crank extensions 29. The operative ends of the arms are offset or recurved over the upper edges of the side members 17, 18 of the roller table. The shaft 23 is rocked by worm gear through a countershaft carrying a worm-wheel in gear with a worm driven by a friction coupling on the armature shaft of a reversible electric motor. A turntable may also be provided on the front roller table so that the work can be lifted and then turned in its own plane through an angle of 90‹ more or less before being rolled down to final thickness after initial rolling to a length corresponding to the width of plate required. The two adjacent feed rollers between the pairs of centering-arms have the middle portion of their length reduced to accommodate a turn table 38, Fig. 5, normally below the surface plane of the roller table. The table 38 is carried by an hydraulic cylinder 39 which is movable on a fixed ram 42 and carries a gear-frame 45, containing a bevel pinion 46 splined to the ram, and a bevel wheel 47 mounted on a shaft 48 provided with a ratchet wheel 49, which is operated by a pawl centred about the shaft and pivoted to the rod 51 with an adjustable head 53. On admitting pressure to the ram the turn table is raised, and when the head 53 engages a socket 52 fixed to the ram the table is automatically turned the desired amount by the wheel 47 rolling on the pinion 46, the movement being limited by a stop 54. When the table is returned it descends without rotation. In a modification in which the rotation is not effected automatically, the gear frame is replaced by a frame supporting an elongated spur pinion 56, Fig. 9, which is rotated to any desired angle in either direction by a rack 57 carried by a cross-head 58, which is traversed on a guide rod 63 by a pair of hydraulic rams 59, 60. According to the Provisional Specification the turn table may be rectangular.

Title: Method of making alumina-containing catalysts
IPC: C10G35/06
Filed: 1952-06-20
Abstract: An alumina-based catalyst is prepared by forming an aluminium alcoholate of a water-soluble alcohol, hydrolyzing the alcoholate with an aqueous impregnating solution containing a catalytic component to form an impregnated hydrous alumina, and drying and activating the product.  The alcoholate is formed by reacting aluminium metal with anhydrous ethyl, propyl, or isopropyl alcohol in the presence of iodine or mercuric chloride as catalyst, and is then hydrolyzed by mixing with the impregnating solution in a mixing nozzle or centrifugal pump, the alcohol being recovered by distillation.  Impregnating solutions mentioned are silica hydrosol, and aqueous solutions of ammonium molybdate, ammonium dichromate, ammonium metavanadate, potassium dichromate, potassium nitrate, cerium nitrate, calcium nitrate, chromic acid, boric acid, tungstic acid, ammonium tungstate, and phosphoric acid.  Hydrous alumina-silica formed by hydrolysis with silica hydrosol may be mixed with one of the other impregnating solutions before drying and activating.  Drying is carried out at 250 DEG -400 DEG F. and activation at 800 DEG -1450 DEG F.  The slurry formed by hydrolysis may be emulsified with oil or n-butanol or passed through baths of these substances to form spherical gel particles; the slurry may also be dried by spraying into hot air or flue gas, or into an atmosphere containing ammonia, methylamine, sulphur dioxide, hydrogen sulphide, or boron trifluoride.  Examples describe the preparation of catalysts consisting of alumina - boria, alumina - silica - molybdena, alumina - silica, alumina - vanadia, alumina-tungstia, alumina-phosphoric acid-chromia, and alumina-molybdena; reference is also made to alumina-magnesia and alumina-silica-magnesia catalysts.  The catalysts may be used in hydro-forming, aromatization or cracking of hydrocarbons or in processes involving dehydration, dehydrogenation, hydrogenation, esterification, isomerization, condensation, polymerization, or amination.  Specification 663,128 is referred to.

Title: Apparatus for producing a compressed gaseous medium by combustion
IPC: F02K7/04
Filed: 1933-05-31
Abstract: 424,955. Gas turbines. ANDREAU, J. E., 73, Boulevard Montparnasse, Paris. May 31, 1933, No. 15750. Void [Abridged as open to inspection under Sect. 91 of the Acts, Dec. 1, 1933]. [Class 110 (iii)] In apparatus for producing products of combustion for use in a turbine &c., of the type in which an oscillating wave is set up in the explosion chamber, the rhythm of the ignition is maintained in resonance with the fundamental frequency of the wave. In Fig. 1 the explosion chamber 1 is fitted with a flexible admission valve 2 and a similar discharge valve 4 leading to a receiving chamber 3 and a delivery nozzle 5. The spark at 6, derived from a transformer 7, is controlled by a continuously vibrating blade 9. The periodicity of vibration may be altered by moving a weight 101 automatically along the blade in accordance with variations in mean pressure in the explosion chamber 1. In Fig. 9, carburetted air is drawn into the chamber 1 past a valve 15, and pure air through a surrounding shield 30 and past valves 2. This latter air serves to cool the sparking plugs 6, of which there may be a number firing in definite sequence, and also the intermediate passage 13. Starting may be effected by admitting compressed air intermittently by a valve controlled by a vibrating blade. In Fig. 9 a hand-actuated pump 26 is used to supply carburetted air on starting. Communication with the delivery nozzle 5 is prevented by a valve 31 until pressure has been established in the chamber 3. In the modification shown in Fig. 6, the charge of carburetted air drawn past the valve 15 by the explosion wave is precompressed by a differential piston 16, the chamber 17 at one end of which is open to the pressure at one point in the explosion chamber. This piston may also control the ignition, and the injection of fuel oil when such is used. The ignition distributer may be driven by an electric motor the speed of which depends upon the pressure in the chamber 1.

Abstract: 554,013. Drift-sights. PIREY, J. M. J. A. DE., (Representative of LAURENT, A. J.). Dec. 8, 1941, No. 15807. [Classes 97 (i) and 97 (ii)] In a drift-sight for aircraft, observation of a ground object is effected without the interposition of lens, and an image of a rotatable drift-sight screen is reflected into the field of view; the screen may have parallel transverse lines thereon to provide data enabling ground speed to be calculated by a slide rule. As shown, a drift-sight screen 18 is illuminated by a lamp 11, condenser 12, and reflecting prism 13, and its image, reflected in a plane-parallel glass plate 15, is viewed simultaneously with an object on the ground 17. A concave reflector 14, in conjunction with the under surface of the plate 15, may form a second image on a glass plate 125, the two images serving to assist in locating the observer's axis of sight. The screen 18 is rotatable by a handle 23 on a scaled drum 22 readable against a pointer 25. The screen may be opaque, and have a number of parallel translucent lines flanked by two lines perpendicular to them which are used for the drift observations. The time of transit of an observed object across the spaces between the parallel lines, and knowledge of the height of the aircraft &c. enable the ground speed to be calculated. A slide rule, graduated logarithmically may be attached to the apparatus to facilitate calculation.
