Title: Improvements in or relating to protective arrangements for electrical apparatus
IPC: H02H3/28
Filed: 1931-05-01
Abstract: 377,321. Protective cut-out arrangements. KAPP, R. O., CARROTHERS, C. G., 25, Randolph Crescent, London, WHITCHER, J., Rosegarth, Manor Road, Ruislip, Middlesex, and GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London. May 1, 1931, No. 12914. [Class 38 (v).] In a protective system for apparatus having an earthed neutral, particularly transformers, against internal earth fault, the protection being unaffected by faults outside the apparatus electrically interlocked relays are provided which operate respectively in accordance with the flow of current in the neutral-to-earth connection and on the flow of power to an earth fault external to the apparatus. In the arrangement shown in Fig. 1, a directional relay 9 when closed completes the local tripping circuit of the coil 7 and cuts out the transformer provided the relay 13 is closed at the same time. The directional relay has one of its coils 12 energized from a transformer 3 in the earth connection from the neutral of the power transformer 1 and its other coil energized by three summation transformers 6 in the phase lines supplied by the transformer. The operating coil 14 of the relay 13 is in series with the coil 12. When the transformer 1 supplies power to an external earth fault the directional relay which is normally open remains open. When, with an internal fault, power is supplied (from other parallel-connected transformers) to the fault both relays are closed and the circuitbreaker is tripped. In a modification, Fig. 2, the transformer 3 supplies a normally open earth relay 13 and one coil of the normally open directional relay 9 in series. The other coil of the directional relay and the coil 17 of an additional normally closed earth relay 16 are supplied in series from the summation transformers 6. The tripping circuit is connected as shown. With an external fault the relay 16 opens quickly, 13 closes and 9 remains open, so that the trip circuit is incomplete. When the fault is cleared, relay 16 closes slowly so as to allow relay 13 to open first. For an internal fault 16 opens and 9 closes thereby closing the tripping circuit. In an arrangement which is not dependent on the supply of power to an internal fault from other parallel-connected apparatus directional relays are not employed. For an external fault the non- directional relay opens before the earth relay closes, so that the trip circuit is incomplete. For an internal fault the non-directional relay remains closed and the earth relay closes completing the tripping circuit.

Title: Improvements in or relating to regulating arrangements for steam power plants including a steam boiler having low storage capacity
IPC: F22D11/00
Filed: 1960-04-11
Abstract: 930,381. Steam power plant; turbines. SIEMENS - SCHUCKERTWERKE A.G. April 11, 1960 [April 11, 1959], No. 12920/60. Addition to 856,323. Classes 110 (3) and 122 (3). In a control system for a steam power plant comprising a turbine 1, 3, a boiler 7 with low storage capacity and a working medium storage means, e.g. a cold condensate accumulator 10, and in which the supply and discharge of the working medium to and from the storage means 10 is regulated in accordance with turbine load by first and second pumps connected in series by a conduit; the first pump 30 pumping water from the condenser 17 and the second 22 being capable of pumping water from the storage means via a pipe 54 connecting the storage means to a point in the conduit between the two pumps, the throughflow of the second pump, which throughflow controls the supply and discharge of water to and from the accumulator, is regulated in dependence on the ratio of the quantities of water passing through the first and second pumps respectively. The pump 30 discharges through a valve 29 operated in accordance with the water level in the condenser 17 by a controller 32. The throughflows of the pumps 30 and 22 respectively are measured by flow devices 37 and 38 which transmit signals through lines 39 and 40 respectively to a comparison controller 36 which controls through line 41 the motor 42 driving the pump 22. The turbine inlet valve 4 is influenced by a controller 5 influenced by turbine load and by signals such as e.g. n and e dependent on speed and electrical characteristics respectively. Variations in turbine load are signalled via a line 55 to a controller 34 which in turn transmits a signal by line 56 to the controller 36. During normal operation the quantities flowing through both pumps 22 and 30 are equal and no condensate is supplied to or taken from the accumulator 10. If, however, due to turbine load alteration a signal is sent to controller 36 the output of pump 22 is changed accordingly. After the necessary regulation has been effected the controller 34 is reset by a signal 43 from the controller 36 which is reset by a feed-back signal 44 to restore the water level in the accumulator 10 to its normal value. In a modification, Fig. 2 (not shown), the controller 36 acts on a valve on the delivery side of the pump 22 and the signal 44 is dependent on the difference in water level in the accumulator and in the feed-water container. In a further modification, Fig. 3 (not shown), the storage means is of the displacement type and the controller 36 is reset by a device influenced by temperature fluctuations in the storage means.

Filed: 1928-05-02
Abstract: 289,825. Radulescu, D. May 2, 1927, [Convention date]. Drawings to Specification. Scrubbers and washers.-The steps of introducing supersaturated or condensing water vapour into the gas, imparting a whirling motion to remove solid and liquid particles by centrifugal action, and then passing the gas through a centrifugally produced veil or film of liquid, are repeated twice or more in purifying furnace &c. gases. Apparatus comprises a conduit within which is mounted a series of radial stirrer blades rotating at high speed to impart a whirling motion to the gases and dividing the conduit into a number of chambers. Water vapour injectors are arranged opposite alternate stirrers causing the corresponding chambers to be filled with con. densing vapour. Near each of the other stirrers a water jet is located providing a water sheet. The stirrers, which may comprise 3-6 pairs, may exert suction and may be oppositely disposed to produce eddying effects.

Title: Improvements in electromagnetic speaker units
IPC: H04R11/00
Filed: 1927-05-14
Abstract: 282,279. Waddell, B. F. May 14, 1927. Magnetic instruments.- An electromagnetic unit for a loud-speaker comprises a permanent magnet and co-operating armature with means for balancing the armature in the air gap between the magnet poles, means for completing the electromagnetic circuit through the armature. and a fixed means of leakage of magnetic flux across the poles of the permanent magnet the armature being supported near one end thereof bv this fixed means, which serves also to amplify the electromagnetic flux in the armature. The fixed means preferably consists of a reed of magnetic material. In the construction shown, a yoke 2 of non-magnetic material is secured across the terminals of a horseshoe magnet 1 with metal spacing blocks 4 of high permeability in between. The yoke is curved at the centre, providing a circular receptacle, the walls of which are extended laterally to form lugs 6, on which is clamped a non-magnetic bar 7, which retains the speech-current coil 9 in the receptacle. A reed 10 of magnetic material is secured by screws 11 to the lugs 6, an armature 16 being secured near one of its ends to the centre of the reed and passing through the coil 9, so that its other end lies between the ends of pole shoes 12 secured by screws 13 to the blocks 4 and by screws 14 to the lugs 6. The screws 11, 14 are of iron and preferably abut, although a slight air-gap may be left between their adjacent ends. A rod 17 connects the armature with a diaphragm, preferably of the form described in Specification 297,131. A leakage of permanent magnetism occurs from one magnet pole to the other through the screws 14, 11 and reed 10. whilst the electromagnetic circuit is completed through the armature 16, reed 10, screws 11, 14, pole-shoes 12, and air-gaps. When the telephonic current produces magnetic flux in one direction, the armature moves to reduce one air-gap and at the same time picks up some of the permanent magnetism of the correct polarity from the reed, thus amplifying the magnetic flux in the armature, i.e. some of the magnetism which was flowing straight across the reed is now deviated to a path through the armature and the reduced air-gap. In a modified construction, the reed 10 is extended to the outer sides of the magnet 1, its outer ends being clamped to the blocks 4 by screws having the same relation to the screws 13 as the screws 11 have to the screws 14.

Title: Improvements relating to the reproduction of video signals from magnetic tape
IPC: H04N9/45
Filed: 1967-03-20
Abstract: 1,120,348. Interpolating circuits. AMPEX CORP. 20 March, 1967 [24 March, 1966], No. 13014/67. Heading G4. [Also in Division H3] In a system for playing back recorded colour television signals wherein the played back signals are corrected for phase error by means of electronically variable delay lines 13 and 18 controlled respectively by a phase detector 14 comparing line synchronizing pulses with a reference source and a colour burst comparator 21, the stepped wave output of the detector 14 is converted into a smooth curve with the aid of a ramp generator 51. It is assumed that successive errors when the same head scans the same line will be similar, and capacitors 31 store error differences for each combination of head and line, e.g. there may be 16 capacitors when there are four heads. The outputs of the two phase comparators 14 and 21 are added (26) and fed directly and via a delay (28) of one line period to a subtractor 27 which thereby produces outputs corresponding to the difference between the current phase error and that for the preceding line. These outputs are stored in the appropriate capacitor 31 and read out when required with the aid of a timing generator 47 synchronized with the reference pulses on line 16 and a logic circuit 42 which is supplied with inputs on lines 43 and 44 indicating which line is being scanned by which head. The voltage stored on the appropriate capacitor 31 when read out controls the slope and direction of the waveform produced by ramp generator 51 the output of which is combined with that of the phase detector 17 to provide the control voltage for the delay line 13.

Abstract: 1,108,831. Bottling. FARROW & JACKSON Ltd. 14 March, 1967 [24 March, 1966], No. 13089/66. Heading B8T. [Also in Division F2] A filling nozzle in a bottling machine, which comprises a generally frusto-conical spreader 26 surrounding an air vent tube 14 so that liquid flowing down a liquid supply pipe 16 is spread radially outwards against the wall of a bottle &c. into which a valve 15 has been introduced, has vent ports 25, 28 to equalize the gas pressure above and below the liquid envelope. Raising a bottle &e. through a guide 29 against a seal 23 slides upwards a sleeve 19 and an integral tube 18, away from a valve washer 20, to allow liquid to flow down the pipe 16. As the tube 18 rises, first the lower vent port 28 communicating with the vent tube 14 is uncovered; then the spreader 26; and then the upper vent port 28, above the spreader. The upper vent port 28 passes radially through a tapered projection (27), Fig. 3 (not shown), on the vent tube 14, extending out to the inner surface of the liquid supply pipe 16. Radial fins (38), Figs. 3, 4 (not shown), on the vent tube 14, centre the latter within the liquid supply pipe 16. A number of the filling nozzles are described as arranged around the lower periphery of the tank (1), Fig. 1 (not shown), of a rotary table suction bottle filling machine in which the liquid level (4) is maintained constant by a float (5), and tubes 9 on top of the vent tubes 14 extend above the level of the liquid into the suction space. Alternatively, the filling nozzles can be used in gravity feed apparatus. In this form, a separate device is provided for removing surplus liquid from the pipe 16 &c. as the filled bottle is withdrawn. In the form shown, the tube 18 and the sleeve 19 are made of plastics. In a modification, the tube (18), Fig. 6 (not shown), and the sleeve (19) are made of stainless steel and are fitted with an internal sleeve (39) of P.T.F.E.

Abstract: 380,795. Knitting - machines. HEMPHILL CO., Central Falls, Rhode Island, U.S.A.-(Assignees of Lawson, R. H. ; Pawtucket, Rhode Island, U.S.A.) March 20, 1931, No. 13116/32. Convention date, March 29, 1930. Divided on 375,379. [Class 74 (ii).] Relates to means for preventing the formation of an eyelet or eyelets in the knitting of split work hosiery as, e.g. when commencing the formation of the ring toe 11. The invention is described in connection with the machine of Specification 375,379, in which the leg portion is knitted at the side of the machine corresponding to the auxiliary knitting cams so that the leg and instep may be knitted of the same yarn. The cam 105 is inserted to engage only the long butted jacks 33 in the course preceding the formation of the ring toe, so that the corresponding needles engage yarn at the feeder corresponding to the auxiliary cams 17<1>, but are not raised high enough for the old loops to drop off their latches. Thereafter and during rotation in the same direction to form the first course of the circular knitted ring toe, the needles knit at the regular set of knitting cams 16<1>. The three needles by drawing yarn at the auxiliary set of cams draw or tighten the stitch at the first instep needle and so prevent a long stitch or eyelet at the point 142. The cam 105 is brought into operation in the same manner when, after the welt 1 or rib-top has been knitted at the regular set of knitting cams, the yarn is changed for knitting the leg 2 at the auxiliary cams. Specification 375,330 also is referred to.

Patent GB-671947-A (GB)
Title: Improvements in or relating to the production of organic chlorine compounds
IPC: C07C17/00
Filed: 1949-05-18
Abstract: Chloroethylenes and chloroethanes are made by passing a gaseous stream comprising 1 to 5 vols. of Cl2 and 1 vol. of C2H6 into a reaction zone, containing a bed of finely-divided inert solid material, maintained at a temperature in the range 250-550 DEG  C., with a linear velocity sufficient to maintain the finely-divided material in suspension within the reactor and subsequently isolating the desired chlorohydrocarbons.  Small amounts of ethylene (which may be recycled), acetylene, hydrogen chloride and high-boiling chlorinated butenes are also obtained.  With chlorine/ethane ratios of less than 2- 5/1 and a temperature of 500 DEG  C., partial cracking of the chlorinated ethane results in the production of chloroethylenes.  With chlorine/ethane ratios of the order of 2/1 , e.g. 1.7-2.3/1, and a temperature of about 500 DEG  C., e.g. 480-520 DEG  C., a high yield of vinyl chloride is obtained with some ethylene, dichloroethylenes (mainly asym-dichloroethylene) and dichloroethanes (mainly ethylidene chloride).  With these reaction temperatures and chlorine/ethane ratios of above 2- 5/1 , the products are mainly chloroethylenes with little chloroethanes.  As the ratio increases from 3 to 4/1 increasing amounts of trichloroethylene are formed and at the latter ratio vinyl chloride formation diminishes while formation of perchloroethylene and ether high-boiling compounds is quite large.  Vinyl chloride is also obtained by using lower temperatures, e.g. 350-425 DEG  C., together with di- and tri-chloroethanes which may be separately cracked at 600-700 DEG  C. Sand is a particularly useful inert material.  In four examples, chlorine and ethane are reacted in the presence of fluidized 50-100 mesh sand to yield vinyl chloride, ethyl chloride, ethylidene chloride, vinylidene chloride, trichloroethane, trichloroethylene, perchloroethylene, ethylene, acetylene, high-boiling compounds (probably chlorinated butenes) and hydrogen chloride in varying proportions depending on the reaction conditions, as indicated above.

Filed: 1918-08-16
Abstract: 158,522. Lender, M., and Heidelberg, P. Aug. 16, 1917, [Convention date]. Void [Published under Sect. 91 of the Act]. Teaching and training, apparatus for.-An apparatus for training pilots comprises a gimbal-suspended car subjected by means of cam-controlled compressed air cylinders to various disturbances which the pilot endeavours to correct by means of his controls. The varying resistance of the controls and the noise of the engine at different speeds is simulated, and the inversion of the elevator and rudder controls at a critical angle of bank is provided for. The horizon is painted on a tiltable sphere surrounding the apparatus, and the illusion of landing produced by a movable optical system in the base of the car focussed on a moving horizontal panoramic band. The various movements of the apparatus are recorded. Fig. 2 shows the connections to the elevator control. The piston H of a compressed air cylinder G is connected to the car by a link I, and a valve M is actuated by a lever N having a flexible part 0 bearing on a cam K. The lever N is also connected by a spring P and a cord to a sleeve S on the pilot's control lever L. Movement of the control lever is resisted by springs Q and a dashpot R. Movement of the lever L also admits or exhausts air from a cylinder U so as to cause the sleeve S to move away from or towards the fulcrum of the lever L and thereby vary the apparent resistance. The parts are returned to normal position by springs J or by other compressed air cylinders.. The rudder and aileron controls and the optical device &c. are similarly controlled. Fig. 3 shows the means for effecting the changeover of the rudder and elevator control. The rudder-bar W and lever L are connected to parallel rods on which slide blocks A<1>, B<1> connected respectively to the elevator and rudder mechanism, the blocks being moved along the rods as the apparatus tilts. The panoramic film turns with the horizon-sphere.
