Patent GB-489694-A (GB)
Title: Improvements in and relating to remote control systems on three-phase electric networks
IPC: H02J13/00
Filed: 1936-11-02
Abstract: 489,694. Electric signalling and distant control systems; telephony. SANTUCCI, G. Nov. 2, 1936, No. 29785. Convention date, Oct. 31, 1935. [Class 40 (i)] [Also in Group XXXIX] Signalling and distant control over a three-phase network is effected bv rotation of the phase angle of one of the phases, the receiver having two windings arranged normally to produce fluxes in phase or in phase opposition so that they exert no torque. The phase rotation may be effected by insertion of an inductance in one of the phases, but as shown it is effected by superposing on phase 3 a voltage at 90 thereto by means of a transformer having two primaries Va, Vb connected between phases 1, 2 and phase 3, a switch K being provided to reverse the direction in which the phase change is produced. The receiver is of the nature of an induction motor having two windings B2, B3 connected between two of the phases (one of which is to be rotated) and the third, one of the windings being in series with a condenser C to bring the normal current in the windings into phase or phase opposition. The disc D, which operates switches, e.g. mercury switches, may be moved in either of two directions from a central position to which it is spring biassed, or by arranging it like an inverted pendulum, it may be moved to take up either of two stable positions of rest against fixed stops. By connecting receivers to different pairs of phases a number of controls may be obtained. The control may be used for tariff changing in electric supply systems or for producing interruptions of the supply in cases where use for lighting is prohibited, such fraudulent use being indicated by flashing of the lamps. The receivers may also operate audible or visible signals, or may energize a wireless receiver or connect a telephone amplifier and reproducer to a line which may be a supply line so that communication from a signalling station may be effected by wireless or line. The Specification as open to inspection under Sect. 91 comprises a receiving arrangement consisting of a core with three two-phase windings controlling movable members so that it responds selectively to a change in any one of the three phases. This subject-matter does not appear in the Specification as accepted.

Abstract: 190,702. Ram, G. H. E. de. Dec. 21, 1921, [Convention date]. Hydraulic springs.- Consists of a liquid shock which damps both shock and recoil movements in a manner varying with the speed of the vehicle, the arrangement being such that for speeds below a certain limit, recoil is damped to a greater extent than shock, while above this limit the action is reversed. The arrangement comprises a piston 1, Fig. 1, connected to the axle and working in a cylinder 3 having spring-controlled valves 4 - - 7, and ports 10, 11 permitting communications between opposite sides of the piston by the conduit 8. A cylinder 9 has a free piston 9<1> and contains air. If displacements of the piston are not violent, the liquid flows through the ports 10, 11, the nozzleshaped port 10 offering greater resistance to return movement. With violent displacements, the valve 4 is lifted and the piston 9' raised to compress air in the cylinder 9. A partial vacuum results on the left-hand side of the piston, allowing a partial quick return of the piston, followed by a slower return owing to the braking action of the nozzle 10, or if the axle speed is high. a further quick return one to the opening of the valve 7. The air cylinder may be dispensed with. initial movement of the piston 13, Fig. 2, opening a valve 14, the liquid then pushing back a piston valve 19<1> made in one piece with a one-way hydraulic brake 18<1>. The valve 19<1> controls the connections 16, 17, 20 between the two sides of the piston. Return movement is made through a valve 15. The valve 19<1> is opened more or less, according to the speed of the liquid flow. In a modificatign, the valve 19' and piston 18<1> control a valve in a passage between the passage 16 and the right-hand side of the piston, the conduits 16, 17 not connecting.

IPC: C11B1/16
Filed: 1933-10-28
Abstract: <PICT:0426500/III/1> An apparatus for extracting oil from fish livers consists of a digester 5 above which is mounted a settling chamber 15 and connected thereto through a gauge tube 14 provided with a valve for drawing off the oil.  The top of the settling chamber is open to the atmosphere whereby the generation of pressure is avoided. Livers are introduced through a door 5<a> into the digester and steam is admitted through an external pipe to an annular pipe 9 provided with perforations 10.  When cooking is complete, steam is shut off and water is admitted through a second external pipe to the annular pipe 9 and the oil floating on the water rises through the gauge tube 14 to the settling chamber.  When the layer of oil is clear as viewed through the windows 17, the lower layer of water and residues are drawn off through a drain cock 8 of a non-clogging type, until the oil level reaches the valve 18 in the gauge tube, through which it is then drawn off.  The valve 18 is so constructed that solid particles are prevented from discharging with the oil.  Residual oil in the digester is recovered by admitting a further quantity of water, and settling as before.

Title: Improvements in or relating to the starting of internal combustion engines of emergency plants used in sprinkling systems for fire protection
IPC: A62C37/00
Filed: 1923-12-05
Abstract: 229,784. Thornycroft &. Co., Ltd., J. I., and Barford, V. G. Dec. 5, 1923. Turning - gear. - In a sprinkler system for protection against fire, comprising a pump driven by an internalcombustion engine, the engine is started automatically by means of the water in a reserve tank which is supplied automatically to a hydraulic starting motor when the pressure in the sprinkler mains falls below a predetermined value. The starting motor may be a Pelton wheel on a shaft movable axially to bring a worm thereon into engagement with teeth on the engine fly-wheel. The water supply from the reserve tank to the Pelton wheel is controlled by a double piston valve 14 in a casing having an inlet port (not shown) connected to the reserve tank and an outlet port 18 leading to the Pelton wheel jet, the space above the piston 14 being connected by a by-pass to the inlet port. The valve is set by hand in the position in which a lug 21 on the stem 15 is engaged by a sliding member 22, which carries a diaphragm 22a acted upon by a spring '29 and by the pressure in the sprinkler mains. When the pressure drops or is released by turning a cock 28, the member 22 releases the lug 21 and allows the valve 14 to descend and turn on the water supply to the Pelton wheel. The valve is retained in the open position by a member 23 connected by a lever 10 to the shaft 4 of the Pelton wheel. When the engine starts, the shaft 4 is automatically moved axially by the worm gearing and releases the member 23, allowing the valve 14 to descend further and close. The shaft 4 is then held in displaced position by a weighted lever. At the same time, by means of a link 13, the engine throttle is turned from the starting to the normal running position. A fuel cock for the engine may be closed by a lever 25 when the valve 14 is in the upper position shown, and is opened by a lug on the end of the valve stem 15 when the stem is released by the member 22. Instead of utilizing the reserve water pressure to move the valve 14 when released by the catch 22, a spring or gravity load may be provided, and the valve 14 may be a rotary one.

Abstract: 832,726. Sewing machines. PFAFF A.G., G. M. Oct. 1, 1957 [Oct. 11, 1956], No. 30635/57. Class 112 Thread cutting, stitch forming, starting and stopping. In a single-thread chain-stitch sewing machine having a rotary looper, a loop-deflector which serves to locate the preceeding loop with each stitch has arranged thereon a threadseverer and is adapted, after the last stitch of a series, to perform a thread-severing movement which deviates from its normal loop-deflecting movement A shaft 6 driving a rotary looper 7 carries a cam 8 which co-operates with a follower 10 on a shaft 9 to rock the latter. Shaft 9 carries an arm 26 to the free end of which is secured on opposite sides, by means of a screw 28, a loop-deflecting finger 27 and a thread-cutting blade 29. Shaft 9 is so biased axially by a spring 34 that the base of arm 26 normally abuts a bearing sleeve 32. In normal operation each preceding loop 67 is deflected to one side by being engaged between arm 26 and finger 27, so as to position the loop accurately for entry of the looper beak carrying the succeeding loop 68 from the needle 66. When the machine is stopped, shaft 9 is displaced axially, so that the point of arm 26 enters loop 67, whereby blade 29 engages and severs one arm of the loop close to the throat plate. It is stated that the blade may be replaced by a hook or the like adapted to break the thread instead of cutting it. Shaft 9 at its rear end is provided with a lug 35 which is normally disposed outside an aperture 37 in a disc-like member 36 journalled on shaft 9. Member 36 is connected by a link 41 to one arm of a bell crank lever 43, the other arm of which carries a stud 46 disposed adjacent the lower end of a starting and stopping lever 18 journalled on a shaft 58. The upper arm of a lever 57, also journalled on shaft 58, is drawn by a spring 60 into engagement with a stud 65 carried by a bracket 63 fixed to the upper arm of lever 18. A surface 59 on the lower arm of lever 57 lies adjacent an arm of a lever 51, the other arm of which carries a stud 55 disposed adjacent the end of shaft 9. The lower end of lever 18 carries a notched block 17 which, in the running position of lever 18, is engaged by the pawl end 16 of a lever 15. The other end of the latter carries a follower 14 which is engaged, at the end of a stitching cycle, by a stopping cam 13 carried on the periphery of a pattern cam wheel 12. Lever 18 is thereby released, and swings to move a fork 19 for shifting a driving belt 20 from a fast pulley 22 to a loose pulley 21. A member 23 on lever 18 also engages a rotary disc 14 and after running down an inclined portion in the latter, engages a groove therein to stop the machine. During the first part of the movement of lever 18, spring 60 serves to swing levers 57 and 51 for shifting shaft 9 axially, and during the final part of said movement lever 18 engages stud 46 to rock shaft 9, via-lever 43, link 41, member 36, a face 38 of aperture 37 and lug 35, for severing the thread.

Title: A process for the production of aqueous dispersions of bituminous materials
IPC: C08L95/00
Filed: 1929-10-09
Abstract: Aqueous dispersions of asphalt, pitch and other bituminous materials, having melting points of about 100 DEG  to 220 DEG  F., the dispersed particles of which will remain in suspension over indefinite periods of time without any noticeable settling, are made with the use, as dispersing agents, of argillaceous materials such as bentonite and clay, or mixtures thereof, with or without the addition of protective colloids, in an amount not exceeding 10 per cent by weight of the dispersed phase, the temperature of dispersion being not substantially higher than the melting point of the material dispersed so that the average size of the dispersed particles is not substantially greater than 10 microns, the water content of the dispersion being kept below the point (about 40 per cent) where further dilution substantially decreases the suspendability of the dispersed particles, and the dispersion on leaving the dispersing apparatus being subjected, without addition of water, to a rapid beating or whipping action, which may be performed in the beating apparatus described in Specification 334,100, [Class 81 (i), Disinfecting &c.].  By using not more than 10 per cent of dispersing agent, a dispersion is obtained which, when once freed from water, will not redisperse. Bentonite and clay mixtures containing from about 10 to 75 per cent of the former may be used, or bentonite with a protective colloid, e.g. upwards of 5 per cent of alkali casein may be employed.  New Jersey ball clay and casein, swollen with ammonia or sodium borate solution, may be used to give a dispersion containing 1,4 per cent clay, 0,7 per cent casein, and about 70 per cent asphalt, the remainder being water.  The suspendability of the dispersed particles is conveniently tested by centrifuging.  In an example, Mexican asphalt, melting point 105 DEG  F., heated to about 165 DEG  F., and a suspension containing about 5 per cent of bentonite in water, having a viscosity above 45 seconds and preferably a pH of about 7,5, are fed simultaneously, in proportions of 1\ba1/2\be-2 to 1 respectively, to a dispersing apparatus the contents of which are maintained at 105 to 110 DEG  F.  The dispersion obtained is beaten to reduce its viscosity, and has a water content of 30-40 per cent. Specifications 244,135, [Class 81 (i), Disinfecting &c.] and 341,443 also are referred to.
