Title: Improvements relating to vigilance control apparatus for automotive railway vehicles
IPC: B60T17/20
Filed: 1957-08-23
Abstract: 856,053. Automatic brake application. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd., SIMMONS, A. W., and ROBERTS, L. J. Aug. 22, 1958 [Aug. 23, 1957], No. 26689/57. Class 103 (1). In a vigilance control apparatus for rail vehicles, should the pressure in a timing reservoir be allowed to fall too low, it sets in progress a sequence of emergency operations, the changeover from charging to discharging, at a controlled rate, of the reservoir, being arranged to be made by means responsive to the timing reservoir pressure to make the changeover when that pressure reaches a predetermined high value. An electromagnetically-controlled valve 14 controls the charging and discharging of timing reservoir I through chokes 12, 13, respectively, a pressure-switch 15, normally closed, being opened. at the predetermined high pressure to de-energized valve 14 and open exhaust choke 13. The contacts of switch 15 are in series with the coil of relay 16 and an impulse switch 17 in the driver's position. To initiate charging the switch 17 or switches 20, 21 are closed to energize relay 16 and close contacts 18, 19, the contacts 18 being in a circuit controlling valve 14 and the contacts 19 in a holding circuit maintaining the relay coil energized until switch 15 is operated. A deadman's device comprises two foot switches 20, 21, either of which when depressed permits free running of the vehicle and which close contacts 22, 23 when released; further contacts 24 are closed when a reverser key is in forward or reverse and contacts 25 closed when the key is in neutral to permit the release of the deadman switches without brake application; which release normally de-energizes deadman's application valve 26 for brake application. Should the pressure in reservoir 11 fall below a certain value then a switch 30 is operated to energize warning means 29. If a cancelling switch (17, 20 or 21) is not then closed to recharge reservoir 11, then at the further low pressure, the contacts of switch 27 are opened to de-energize the deadman's application valve 26 irrespective of the position of switches 20, 21 to vent the brake pipe, after a predetermined delay, for brake application; the valve 26 is connected to a jumper wire 28 to de-energize similar valves on the rest of the train. The warning device is isolated when the driving position is not operated by opening the contacts of a relay 31 controlled by a switch 32. Specification 856,052 is referred to.

Patent GB-425280-A (GB)
Title: Improvements in or relating to travelling cranes
IPC: B66C13/00
Filed: 1934-09-17
Abstract: 425,280. Overhead travelling cranes. TENNANT, W. J., 111, Hatton Garden, London.-(Motor Terminals Co. ; 420, Lexing- ton Avenue, New York, U.S.A.) Sept. 17, 1934, No. 26699. [Class 78 (iv)] The four depending load-engaging cables of a travelling crane, more especially for raising automobile bodies, are associated with means for drawing the load up tightly against the underside of the travelling frame, thus preventing swinging during transport, and with means for automatically cutting off the power when this position is attained. Fig. 1 shows the general arrangement in plan, the motor 25 driving one pair of travelling wheels 20 to transport the crane bridge on the rails D. Four lifting-ropes 52, carrying eyes or shackles engaging four hooks near the corners of the vehicle body, are connected to a common nut 40 which is moved axially on the screw 30 rotated by the motor 35. Two of these ropes pass from the nut direct to the eyes over the pulleys 90 at the right hand side of Fig. 1, while the other two pass round pulleys 61 ... 64 and over the pulleys .90 at the left hand side. Movement of the nut thus operates all four ropes simultaneously. The screw is provided with a thrust bearing at 31 and can slide in the bearing 32. At the end of the lift, bumper blocks b<4>, Fig. 5, on the bodies near each lifting rope engage converging brackets 101 on the bridge and are wedged in the angle, thus preventing swinging movement of the load. The same movement raises a rod 110 against the action of spring 111 and operates the switch arm 115 to cut out the hoisting motor. In the modification shown in Fig. 6, the converging bracket 130 is moved upwards against the action of the shock-absorbing spring 132 by the bumper blocks b<4> and operates the cut-out through the medium of the rod 110. In a further modification a cradle is interposed between the crane and the load, the shackles and bumper blocks then being carried by the cradle, and the load engaged by the shackles so as to lie closely against the cradle. An electric control circuit for the hoisting motor is described which short-circuits the limit switches during lowering, thus enabling the load to be lowered from the jammed-up position in which the limit switches are opened. As soon as the switches are free, they are re-set automatically by springs ready for the next hoisting operation.

Title: Daylight developing tank for photographic roll films with protective paper strips
IPC: G03D13/06
Filed: 1951-11-14
Abstract: 700,954. Photographic developing apparatus. KEHR, W., and STRAUSS, R. Nov. 14, 1951 [Nov. 25, 1950], No. 26717/51. Class 98(2) A daylight developing tank for photographic roll film with a protective paper strip, of the kind in which the film, after insertion in an auxiliary chamber, is fed into a treatment chamber by withdrawing the paper strip, comprises a core for winding the film within the tank, a device on the core for fastening the end of the film, and means whereby the film end is guided into the open fastening device on withdrawing the paper strip. As shown, the auxiliary chamber 1 is mounted on the side of the treatment chamber 2, and both have a cover in two parts 5, 6. A springy holder 8 holds the film spool 3 by its edges in chamber 1. The inner part 5 of the cover is put in place and the paper backing 4 is drawn over it. The outer part 6 of the cover is then put in place, the paper 4 passing through a channel between the parts of the cover. As the paper is pulled off, the end of the film is lifted by the edge of holder 8 and guided by lugs 8b thereof on to a plate 11 pivoted near the partition 10 separating chambers 1, 2 and resting initially in a notch 13 in a core 14 rotatably mounted in chamber 2. The paper is pulled until resistance is encountered as the film end enters the notch 13. Core 14 is then turned anticlockwise by a handle outside the chamber. Plate 11 drops out of slot 13 and falls against the side of chamber 2. A cranked rod 16, journaled in core 14, has a bentover end 16b which when the core begins to turn, abuts a projection 2b in chamber 2, turning rod 16 so that its cranked portion 16a presses a lever 15. This lever is mounted on core 14 and is initially raised so that the film end passes under its free end, which carries a tooth 15a by which the film is held to the core when lever 15 is'pressed down. Continued rotation of core 14 winds the film into a loose spiral. When resistance is again met with (i.e. when the end of the film attached to the backing paper is reached) a cranked rod 17 journaled in the walls of chamber 2 is turned from outside the chamber to clamp the film against partition 10. Developer is poured in and out by an opening 7, and development proceeds while core 14 is turned in opposite directions to reverse the spiral.

Title: Improvements in or relating to gas blast electric circuit-breakers
IPC: H01H33/70
Filed: 1947-10-06
Abstract: 628,710. Gas-blast switches. REYROLLE & CO., Ltd., A., and AMER, D. F. Oct. 6, 1947, No. 26800. [Class 38(v)] In a gas-blast circuitbreaker having two nozzles, the auxiliary electrode disposed between them. is in the form of a partition which subdivides the gas delivery passage into two annular conduits leading to the two nozzles. The circuit breaker comprises a cylindrical insulating enclosure A<SP>1</SP> having a conducting end cap B containing a nozzle B', and an inner tubular conducting member D having a nozzle D<SP>1</SP>. A domed partition E forming the auxiliary electrode divides the gas delivery passage A<SP>2</SP> into two concentric annular gas delivery conduits E<SP>2</SP>, E<SP>3</SP>. When the moving contact C of the circuit breaker is retracted two arcs are formed, one between the nozzle D<SP>1</SP> and the partition E and the'other between the contact C and the partition E. The gas blast transfers the arc root from contact C to the cap B and the two arcs are blown along the opposite sides of the partition and then axially through the nozzles B<SP>1</SP>, D<SP>1</SP> to auxiliary electrodes F, F<SP>1</SP>, the arcs being thus extinguished. The partition E may be connected to the centre of the insulating cylinder A<SP>1</SP> so that the total voltage may be shared approximately equally across the two gaps. Alternatively a resistance (Fig. 2, not shown) may be connected between the partition E and either of the nozzle electrodes B<SP>1</SP>, D<SP>1</SP>. Specification 542,920 is referred to.

Title: Improvements in or relating to internal combustion engine locomotives
IPC: B61C9/08
Filed: 1927-10-11
Abstract: 306,055. Hagemeister, J. J., and Jensen, E. Jorgen-. Oct. 11, 1927. Railway locomotives, internal-combustion engine and compressed-air.-A locomotive comprises an internal-combustion engine unit A in which the pistons are arranged to serve also as air or other gas compressing pistons on the side remote from the combustion chambers, clutch mechanism 12 for coupling the unit to the driving wheel 2, and a further internal-combustion engine unit B permanently coupled to the driving wheels and arranged to function also as a fluidpressure engine driven by the air compressed by the first engine. The engine B may be identical with the engine A having combustion chambers 15 and air chambers 16 for normal working. To start the locomotive the clutch 12 is disengaged and the compressed air from the engine A is used to drive the engine B; when the locomotive attains sufficient speed the supply of compressed air through a pipe 13 to the combustion chambers 15 is cut off, fuel is admitted, and the engine B works as an internal-combustion engine on one side of the pistons while the other side 16 is still operated for a time by compressed air. Finally, the supply of compressed air to the engine B is completely cut off, the speed of the engine A is synchronized with that of the driving wheels and 'the clutch 12, is engaged, this engagement being preferably effected when the moving parts of the engines A and B are in such relative positions that they balance each other. The exhaust air from the engine B leads to a storage tank 19 and this air is used as the admission air for the internal-combustion engines, giving a supercharging effect. Supercharging may be effected by air supplied directly from the compressors. During normal running both engines A and B may be used to supply compressed air to the tank 19 or to a separate tank for auxiliary purposes such as operating a whistle or for sanding the rails, and one of the compressor chambers may be used to provide the vacuum for a brake. The exhaust pipe C from the engines passes through the air conduit 9 leading from the engine unit A to the engine B so that the air supplied to the latter is heated.

Title: Improvements in or relating to the polymerisation of vinyl aromatic compounds
IPC: C08F12/08
Filed: 1958-08-21
Abstract: <PICT:0859517/IV(a)/1> <PICT:0859517/IV(a)/2> In a continuous process for the bulk polymerization or copolymerization of vinyl aromatic compounds, the compounds in liquid form are heated to between 180 and 350 DEG C., at between 150 and 260 p.s.i.g., for from 0,25 to 2 hours to complete the polymerization before cooling to a maximum temperature of 240 DEG C. to yield polymers of low molecular weight e.g. from 20,000 to 30,000.  Styrene, its derivatives, divinyl benzene, vinyl naphthalene and copolymers thereof with a -methyl styrene, divinyl benzene, acrylonitrile, methyl methacrylate and ethyl acrylate are specified.

Abstract: 170,836. Zaugg, R. Oct. 12, 1921. Electromagnetic switches; latching. - A lockdevice which is released only after energization and de-energization of an electromagnet is controlled by a retarding relay, the circuit to which is completed as each train wheel passes a treadle r, and the armature a of which is retained to keep the lock circuit closed until a predetermined time after the passage of the last wheel over the treadle. The relay armature is kept raised if the energizing current is of a long duration until currents of shorter duration are passed through its coils. Fig. 1 shows one form of relay retarding-mechanism in which the return of the armature a to its lower position is controlled by a dash-pot k; in alternative forms its return may be controlled by a pendulum escapement or a rotating fan-wheel. A number of short currentimpulses due to a train passing the treadle at normal speed causes the armature a to rise and allow the spring contacts c to close. Such brief currents cause the armature to move the lever W, but do not allow movement of the lever n by this lever against the resistance of the dash-pot k<1>. A long impulse, as when a train slows down or stops over the treadle r, allows the lever n to move the pawl V to engage the armature a, which is thereby held raised and locks the pawl V until the next impulse; when, as the armature is raised, the pawl V is retracted by its spring. Figs. 1 and 2 show different forms of lock having two pawls released in succession by energization and deenergization of the magnet e.

Title: Method and apparatus for adjusting reed contact units
IPC: H01H51/28
Filed: 1970-06-04
Abstract: 1318115 Manufacture of sealed magnetic reed contact units HASLER AG 4 June 1970 [6 June 1969] 27047/70 Heading H1N The air gap between the contact ends of the reeds in a sealed magnetic reed contact unit is set by locally heating one of the two reeds by means of a high-frequency heating device and applying magnetic force to deflect both reeds simultaneously so that the reed exposed to highfrequency heating undergoes a permanent material deformation. To enlarge the contact gap the contact unit, which may have reeds on spring hinges 24a, 24b, is inserted within the heating coil 30 so that its reed 23b whose hinge is to be heated has its contact end nearer the electromagnet 40 than the contact end of the other reed 23a as in Fig. 2. The heater and electromagnet are then energized and both reeds move but do not engage each other due to the common polepiece 44 of the electromagnet. On de-energization of the heater and electromagnet the reed 23a restores to its original position but due to material deformation the heated reed does not spring back so far and the contact gap is increased. Fig. 3 shows the upper reed nearer the electromagnet so that with this arrangement the contact gap can be decreased. The electromagnet can be energized to produce opposite poles at its outer pieces 43, 45 when the heater is not energized so as to test the contact operation. During the abovementioned operations a light projector with magnifier may be used (Fig. 1, not shown) to provide an image of the contacts on a screen.

Abstract: 941,776. Hot-water supply systems. T. R. CARRUTHERS. Nov. 25, 1959 [Aug. 26, 1958], No. 27301/58. Heading F4A. Water from a non- ferrous hot-water storage tank flows from a pipe 10, around tubes 6 bearing fins 7 in a heat exchanger casing 1 or in the tank, to be heated by water, from a ferrous boiler, flowing through the tubes 6, before passing back to the tank through an upper pipe 11. Water from the boiler passes from a pipe 3 into the tubes 6, via a shroud 12, to a pipe 5, back to the boiler, beyond a tube plate 17. A pocket of air around the shroud above the pipe 11 prevents water from flowing over the shroud to the storage tank water outside it, but if steam is evolved from the boiler water it flows through the pocket to the pipe 11 while any excess water flows into a central expansion tube 13 through orifices 15 in a sleeve 14 (which may be a filter) around the upper part of the tube 13 and through an orifice 16 in the tube to mix with the storage tank water at the bottom of the heat exchanger. On cooling, a small amount of tank water is drawn up the tube 13 to mix with the boiler water. The Provisional Specification describes a heat exchanger in which water from a storage tank flows through the finned tubes and the water from the boiler flows around the tubes. Specification 941,180 is referred to.
