Title: Improvements relating to railway and like vehicle brakes
IPC: B61H13/02
Filed: 1919-12-01
Abstract: 159,042. Harper, W. F. N. Dec. 1, 1919. Actuated or applied by relaxation of pull; hand-actuation.-The brakes of a vehicle are controlled by a connection to one end of a link or shackle of the usual coupling so that application is effected, as by springs, when the coupling is slackened or broken. As shown, the brakes are adapted to be applied by a spring f acting on togglelinks e connected to the brake blocks a and can be released by the hand-lever b, lever c, and links d. For automatically releasing the brakes by the tightening of the coupling, the hand-lever is connected by the bellcrank g and chain k to the end of the link i of the coupling. A dash-pot k may be provided to prevent the too sudden application of the brakes and there may be a spring l for avoiding shock to the mechanism when the tractive effort is suddenly applied. According to the Provisional Specification, the coupling may act directly upon the releasing-spring and a hand-wheel and clutch may be substituted for the hand-lever.

Title: Improvements in and relating to rectifier traction equipments
Inventor: VERTIGEN DEREK HARRY
IPC: B60L9/26
Filed: 1957-09-24
Abstract: 890,496. Rectifying. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Sept. 10, 1958 [Sept. 24, 1957], No. 29963/57. Class 38 (2). [Also in Group XXXVII] Traction motors supplied with rectified current can be started only if all the rectifiers are excited, the control being effected jointly by a relay E1 (Fig. 1) which is energized to produce closure of the circuits of rectifiers RA1-RA4 when excitation current flows in one or more of the rectifiers and by a relay E2 which causes opening of the rectifier circuits if one or more of the rectifiers fails to excite and thus causes an out-of-balance current to flow through E2. The rectifier circuit contactor coils LA1-LA4 (Fig. 3) also have interlock contacts LA1<SP>1</SP>, LA3<SP>1</SP> in the circuits of the motor contactor coils M1-M4 so that if, at any time, the excitation of one or more of the rectifiers should fail, the motor contactors, as well as the rectifier contactors, are opened. Cut - out switches CO1/2, C03/4 enable a single pair of motors and rectifiers to be used, further contacts CO<SP>1</SP>1/2, CO<SP>1</SP>3/4 being provided so that the appropriate pair of the current transformers CT1-CT4 in the excitation circuits are cut out and relays E1 and E2 continue to function in respect of the rectifiers remaining in operation. The tapping switches TS (Fig. 2) comprise a sequence switch consisting of a cam-operated contactor group which is moved in a notch-bynotch manner correspondingly with the master controller. Indicator lamps provided on each unit of multiple unit equipments fail to light if any of the rectifiers in the units fail to excite. Specification 819,674 is referred to.

Title: Improvements in or relating to forced-flow vapour generators
IPC: F22G5/00
Filed: 1958-09-19
Abstract: 899,359. Tube walls for furnaces. BABCOCK & WILCOX CO. Sept. 19, 1958 [Sept. 20, 1957], No. 30036/58. Class 51 (1). [Also in Group XIII] In a top-supported forced flow once through steam generator of the kind described in Specification 862,183 in order to ensure that the average temperature at any horizontal crosssection in each furnace wall is approximately the same, the wall tubes are horizontally divided into series connected double hairpin groups 44, 45, 46 which are connected between vertically-spaced horizontal headers common to all wall groups. The lower return bends of the groups 45, 46 are connected to enthalpy equalization headers 54, 57 which are located adjacent the junctures of the front and side walls of the generator and are connected between water drain collection and distribution headers 53, or 56 and 55 or 58 respectively. A downcomer 41 from an economizer 32 leads to a distribution header 43 for the first tube group 44 and an upflow tube 50B from the distribution header 43 of the group 46 is trifurcated for connection to three tubes 51 leading to a header 59. From the latter water passes through an enthalpy equalization header 60 in parallel paths through downcomers 61 to supply tubes 63 which lead to screen and baffle tubes 25, 64 respectively. Each generator wall includes metal webs 15 welded to adjacent tubes as shown in Fig. 5. In a modification, the upflow delivery tubes of one group are connected immediately to the collection header of the next group above it, return-bent tubes being interposed between extra drain headers and the corresponding distribution headers. In a further modification, the arrangement shown in Fig. 3 is modified in that the return-bent tubes in the same wall groups, e.g. tubes 48A, 48C in group 44, are adjacent each other instead of being spaced by the upflow tubes 48B.

Title: Hydraulic ram and selector mechanism
Inventor: MORRISON WILLIAM MCKENZIE
IPC: F15B15/20
Filed: 1958-09-24
Abstract: 860,665. Hydraulic apparatus. TURNER MANUFACTURING CO. Ltd. Sept. 4, 1959 [Sept. 24, 1958], No. 30535/58. Class 69 (2). An hydraulic ram and selector mechanism comprises a hollow piston 4a in a cylinder 1 supplied with hydraulic fluid, and a hollow selector plunger 8 disposed within the piston and manually or otherwise controlled to vary its position within the piston to control a pair of fluid control valves 6, 7 exposed respectively to the pressure prevailing at opposite ends of the cylinder so as to cause the piston to move in one direction or the other until it reaches a position in which the valve previously opened by the selector plunger is closed. The selector plunger has cam surfaces 14, 15 which, when the plunger is moved relative to the piston, open one or other of the valves 6, 7. When the valve 6 is opened, fluid supplied from a pump or accumulator connected to an inlet 5b passes through the valve and a transfer port 25 to the right-hand side of the piston which is thus moved to the left relative to the cylinder and plunger until the valve is disengaged by the cam surface and the piston locked in position. When the valve 7 is opened, fluid in the righthand end of the cylinder flow through the valve and the hollow interior of the plunger or an outlet 18 until the valve is disengaged by the cam surface. The size of the valves and the profiles of the cam surfaces may be varied to provide different speeds for the forward and reverse strokes. The movement of the plunger may be controlled manually directly or by a cable 12 connected by a lever 11 to the plunger, the lever being spring-urged to a neutral position, by solenoids, or by pneumatic or hydraulic fluid at low pressure supplied to one side or the other of a piston connected to the plunger.

Title: Process for the catalytic treatment of paraffin hydrocarbons
IPC: C07C5/333
Filed: 1936-11-09
Abstract: Paraffin hydrocarbons, particularly normally gaseous hydrocarbons, are dehydrogenated to the corresponding olefines at temperatures of about 400-770 DEG  C. in the presence of a catalyst consisting essentially of a major proportion of granular activated alumina and a minor proportion of chromium sesquioxide which has been prepared by the calcination at temperatures substantially above 300 DEG  C. of natural aluminium oxide or precipitated aluminium hydroxide.  The alumina is preferably calcined at 600-900 DEG  C., and may be further activated by leaching or treatment with air or other gases, and is then impregnated in granular form with chromium nitrate, chromic acid or ammonium chromate solutions and then heated.  The chromium sesquioxide is usually present in an amount of less than 10 per cent by weight, preferably 2-5 per cent.  The process is preferably carried out in the absence of water vapour, and hydrocarbons containing 3 or 4 carbon atoms are treated at temperatures of 500-650 DEG  C.  The pressure may be sub-atmospheric, atmospheric or increased up to 35 atmospheres, preferably about 3-7 atmospheres. The contact time of the hydrocarbons is usually less than 50 seconds, preferably less than 20 seconds, e.g. 0,5-10 seconds.  The catalyst may be regenerated by oxidation at 500-600 DEG  C. followed by reduction with hydrogen and the regeneration may be accomplished at regular intervals, e.g. 1/2 -1 hour.  A prolonged reduction permits a longer period of use of the catalyst at a lower activity.  The Specification refers to the treatment of butane, iso-butane and propane and illustrates the effects on yield of variation in operating temperatures, time and the addition of water vapour. Specifications 462,349 and 464,957 are referred to.

Title: A liquid removal system
IPC: B63B27/24
Filed: 1963-08-02
Abstract: 1,058,244. Emptying tanks. ISHIKAWAJIMA - HARIMA JUKOGYO KABUSHIKI KAISHA. Aug. 2, 1963 [Aug. 2, 1962], No. 30702/63. Heading B8T. A relatively small secondary tank is in fluid communication with a main tank, and a pump in fluid communication with the secondary tank draws liquid from the main tank through the secondary one, the latter being associated with means for reducing the pressure therein. The main liquid storage tank 12 of a ship is subdivided by bulkheads 14 into a number of compartments, and a secondary airtight liquid tank 16 is adjacent the main one. Centrifugal pumps 36 draw liquid from the tank 16 through bell mouth fixtures 44, valves 42 and pipes 40, 56 and supply it to receiving apparatus 57. The removal of liquid from the tank 16 reduces the pressure therein whereby, when valves 48 in a pipe line 46 are opened liquid is drawn from the main tank through bell mouth fixtures 50 into the tank 16. When the main tank liquid level reaches a point where air is drawn into the tank 16, and liquid within the latter reaches a predetermined low level, a valve 74 is opened and an ejector 68 supplied with compressed air from a tank 64 is operated to remove air from the tank 16, to bring its pressure and liquid level back to the normal operating position. If the quantity of air drawn into the secondary tank is so great that the liquid level cannot be prevented from falling below a critical level by the ejector, a three-way valve 58 is adjusted to return liquid to the tank via pipes 60 and valves 62. The tank 16 can be divided into a number of compartments to provide for more than one type of fluid to be separately removed from its corresponding main tank.

Abstract: 228,305. Ross, T. W., Ryder, C., and Metropolitan-Vickers Electrical Co., Ltd. Dec. 7, 1923. Induction relays; cut-out arrangements.-A phase-balance relay for a polyphase system comprises a number of induction-type relay elements each provided with a pair of operating coils producing opposed torques upon their respective discs and energized in accordance with the currents in the several phases of the system taken in pairs, so that the compound relay responds to arithmetical values of current differences between the phases of the system. As shown applied to a three-phase system, two similar induction discs 1. 12 with driving magnets 10, 11 and 12, 13 are employed. The magnets 10, 12 are energized in series from the current in one phase of the system from the terminals 21, the magnet 11 from another phase from the terminals 18, and the magnet 13 from the third phase from the terminals 19. Each magnet has associated with it the usual magnet 15 carrying a phase-displaced current derived directly from a secondary winding mounted on the central limb of the main magnet. This magnet may be easily saturable, magnetically, or the secondary winding may feed the magnet 15 through an easily saturable transformer 23, as shown, so as to render the response of the induction elements directly proportional to the currents and avoid the usual square low characteristics. The relays have movable contact-arms 3, 4 connected to one of the terminals 9 and fixed contacts 5 .. 8 connected to the other terminal 9. If the currents in the three phases are equal to one another, the discs will have no resultant torque and the circuit at 9 will remain open.
