Title: Three-phase four-wire induction meters
IPC: G01R11/40
Filed: 1963-05-01
Abstract: 1,024,248. Induction meters. LANDIS & GYR A. G. May 1, 1963 [March 5, 1963], No. 17195/63. Heading G1Q. In a three-phase four-wire induction meter comprising three drive systems (two only shown) mounted at equal angles relatively to the shaft 1 of a common rotor disc 3, means for compensating for dependence on the rotating field comprises three arms 20 of magnetic material which extend radially inwards of the voltage electromagnets 2 of the drive systems, the inner ends of the arms 20 being a predetermined distance from shaft 1, and a ferromagnetic auxiliary disc 22 mounted on shaft 1 adjacent arms 20 to form the magnetic coupling of the arms. The arms 20 are attached to the voltage electromagnets 2 by non-magnetic screws 21 at the tops of antipoles 5 which extend behind the electromagnets 2, their remote ends lying between the poles of the current electromagnets 4; pieces 23 of an alloy having temperaturedependent permeability may be interposed between arms 20 and antipoles 5 to provide temperature compensation. The airgap d H  between the auxiliary disc 22 and arms 20 is adjusted to obtain the desired field compensation. The rotor disc 3 may be made of thin, radially-slotted aluminium sheets stuck together in an insulated manner with the slots regularly offset from sheet to sheet, or it may be solid, comprising an inner portion and an outer annular portion insulated therefrom. The disc 22 may be mounted above, instead of below, the arms 20; or the whole compensating means may be located at the lower end of the voltage electromagnets 2.

Title: Process and apparatus for the determination of the spatial distribution of radioactivity in an object
IPC: H01J47/06
Filed: 1975-04-25
Abstract: 1512571 Radio-active position detector INSTITUT PASTEUR 25 April 1975 [25 April 1974 27 Aug 1974] 17234/75 Heading GIA [Also in Division H1] A proportional counter detector for sensing the spatial distribution of radio-activity within an object differs from the prior art indicated generally in Fig. 1 in that provision is made for mounting the radio-active sample inside the detector on supports 38. It is stated that this increases counting efficiency since the low energy particles for which the detector is intended e.g. the emission from 125 I , need travel only a short distance before collection on wire 6. In operation 1300 volts are maintained between wire 6 and cathode 8' and a mixture of gases e.g. argon and methane is introduced into chamber 9 to raise it to a pressure above atmospheric. Radio-active emission e.g. γ-rays ionizes the gas creating a charge on wire 6 resulting in a current pulse to each end of the wire 6. The difference in timing of such pulses from the two ends is sensed by a time-amplitude converter D receiving signals from threshold detectors 14 connected to the two wire ends. The resulting amplitude is registered as a position along a horizontal axis on multi-channel analyzer E and all the particles for each position are registered along a vertical axis to produce a histogram. Pulses below a given minimum amplitude, indicative of particles travelling too far, are eliminated by gating converter D receiving pulses from a minimum threshold detector 18. Two dimensional measurements may be made.

Title: Improvements in and relating to ammonia refrigerating apparatus
IPC: F25B17/00
Filed: 1924-07-18
Abstract: 241,291. Hempel, H. July 18, 1924. Refrigerating, absorption machines for.-In a reversible apparatus the upper part of a generator-absorber a is connected to a rectifier b and thence through a ball-check valve to a pipe f leading to a condenser c and evaporator d. The lower part of the generator-absorber is also connected through a check valve with the pipe f, the arrangement of the check valves being such that outward flow of gas from the vessel a takes place from the upper part of the chamber and through the rectifier only, and the return flow proceeds only through the pipe leading to the bottom of the vessel. The two valves may be contained in the same or in separate casings. A displacing chamber i open only at the bottom is arranged in the generator-absorber a above the heating device h. The gas, such as ammonia, expelled on heating from the liquid in the chamber a fills the displacement-chamber i until perforations in a pipe k extending across the bottom of the chamber are exposed. The gas passes into the pipe and is conveyed through its turned-up end pieces l to the upper part of the chamber a. A cooling coil arranged in the displacement chamber is supplied continuously with cooling fluid from the condenser c, the effect of the cooling during generation being practically negligible when the liquid has been forced below the level of the coil.

Patent GB-174604-A (GB)
IPC: C06F1/26
Abstract: 174,604. Duhanot, E. Jan. 26, 1921, [Convention date]. Matches.-Matches are supported in the course of manufacture in a series of plates 1, Fig. 3, having transverse grooves 2 for reception of the ends of the sticks so that the finished matches may be removed without stopping the movement of the plates. The guide-tracks supporting the plates offer a sinuous course sufficiently long to ensure the drying of the matches after travelling over the sulphuring or paraffin bath 25 and dipping arrangement 26. Inside the circular portions 9 of the guides move toothed wheels which engage notches 3, 4 in each plate and deliver it to a rectilinear portion 8 of the guideway. In order that the notches should not become entangled when passing over the series 10 of the wheels, i.e. on the inside of the curve, the wheels have fewer teeth than the series 11 so that consecutive plates are spaced further apart; the series 10 rotate considerably faster than the series 11 to render uniform the feed of the plates. The match sticks are initially delivered by a filling hopper 20 and placed in position by means of a sliding platform 19, which may be controlled from the general shaft 18. The finished matches are removed by a series of small blades 21 ,Fig. 7, penetrating into the grooves, and are collected on a conveyer belt 22 for delivery to a boxing-device. During this operation, the plates are held between two friction wheels which assist the wheels 10<1> to carry on the plates. The machines may accommodate sticks of different sections by suitably arranging the elements for distributing and fixing the sticks in the plates. The Specification as open to inspection under Sect. 91 (3) (a) states that two similar machines may be employed arranged face to face, both being driven by a single shalt 17 and fed by a single distributor 20. This subject-matter does not appear in the Specification as accepted.
Patent GB-665402-A (GB)
Title: Improvements in coloured textile materials
IPC: D06P1/645
Filed: 1949-07-01
Abstract: Cellulose ester or ether textile material coloured with a dye which is not normally resistant to gas fading (e.g. an aminoanthraquinone dye) has incorporated therein N : N1-dibenzylethylenediamine (e.g. in an amount of 0.3-1 per cent based on the weight of the material), whereby the resistance of the colourations to gas fading is improved. The incorporation of the diamine may be effected by treating the coloured material with a solution of a diamine in a solvent which does not have any undesirable action on the cellulose ester or ether, or preferably by applying (advantageously by padding) an aqueous emulsion of a solution of the diamine in a water-insoluble organic solvent therefor.  In examples: (1) N : N1-dibenzylethylenediamine is dissolved in a solution of completely sulphonated glyceryl triricinoleate, a polyethyleneglycol monolauryl ether and a polyethyleneglycol dioleate in dioxane and toluene, the solution is stirred into water and the resulting emulsion is padded on a cellulose acetate fabric dyed with 1 : 4-di-(methylamino)-anthraquinone; (2) a cellulose acetate fabric dyed with 1-amino-4-anilidoanthraquinone is padded with a solution of N : N1-dibenzylethylenediamine in aqueous alcohol. Specification 665,401 is referred to.
Patent GB-928068-A (GB)
Title: Radio beacons
Inventor: WAINWRIGHT ARTHUR
IPC: G01S11/16
Filed: 1961-05-12
Abstract: 928,068. Magnetic recording apparatus; signalling. INTERNATIONAL MARINE RADIO CO. Ltd. May 12, 1961, No. 17488/61. Class 40 (2). [Also in Group XL (c)] In a synchronized sound and radio ranging beacon photo-electric means control the emission of the sound signal. Motor 1 drives a releasable drum 15, carrying a magnetically-coated sheet 17 on which the signals for modulating the radio transmitter are pre-recorded, through 1: gearing, and drives a cam plate 20 through 25: 1 reduction gearing to traverse reading head 21 from left to right. The cycle of operations begins when roller 30 is at point a, Fig. 3, of cam profile 53. Between a and i the cam throw develops to reach a maximum at x; during this period rod 23, Fig. 1, is moved to the right to traverse head 21 to read off the pre-recorded information on sheet 17. During the period c to e strip 54 passes over slitted mask 51 to cause photo-cell 50 to conduct and the associated foghorn to emit a first aural signal; a second aural signal is emitted when strip 55 passes over the mask. At point x the head 21 reaches the end of the recording track on sheet 17, and roller bracket 44 encounters ramp 42 to mute the head output. From x to k rod 23 moves to the left to complete, at k, the return of the reading head to its starting position; no further movement of rod 23 takes place during the period k to a, in which bracket 44 clears ramp 43 to prepare the reading head for the next cycle of operations. The prerecorded information consists of a first part such that during the period a to c a warning is transmitted alerting ships' personnel to await the aural signals; at the same time as the second aural signal is emitted the second part is transmitted and comprises a numerical count from zero. To retract the head 21 when the drum is stationary, in order to avoid penetration of the magnetic coating on sheet 17, arm 35, rotatably mounted on stub 36, is provided with extension 37 shaped to draw against spring bracket 31. One end of arm 35 is connected to an actuating arm 38 the opposite end of which engages with the armature of relay 40; the relay armature is urged into its inoperative position by compression spring 58. During beacon operation head 21 is maintained in contact with the surface of sheet 17 by the biasing force exerted by spring bracket 31. The operation of a stop button (not shown) opens a circuit to relay 40 which de-energizes. On operating the stop button, microswitch 60 interrupts the supply circuit to motor 1; to ensure that the microswitch operation is only effective when head 21 is at the beginning of the recording on sheet 17, it is interlocked with the traversing mechanism.

Title: An arrangement for indicating or measuring at a distance the flow of fluids
IPC: G01F1/26
Filed: 1923-07-10
Abstract: 222,951. Roucka, E. July 10, 1923. Pressure-regulating valves.-A device for regulating fluid flow or liquid levels comprises apparatus sensitive to the variations of flow or level and adapted to adjust a valve or gate from a pipe or tank. As shown in Fig. 1, the fluid flows through a pipe 2 which has a flow resistance device 4 connected to the piston 8 of a servomotor 10. The pipe 2 is connected at opposite sides of the valve 4 to opposite sides of a diaphragm 16 which controls the position of a valve piston 22. The piston 22 controls the supply of fluid to and from the servomotor 10. When the flow of fluid through the pipe 2 is normal, the piston 22 is in its neutral position and fluid is cut off from the servomotor. When a variation in flow occurs, the consequent differences of pressure on each side of the valve 4 moves the diaphragm 16 which in turn moves the piston 22 to admit fluid to one side or the other of the servomotor piston 8. The piston 8 is thus moved and the flow resistance device 4 varies the flow of fluid through the pipe 2 to restore the apparatus to a balanced condition. Instead of the valve 4, a butterfly valve mav be employed. Fig. 2 shows apparatus for regulating the velocity of flow of a liquid from a container 80. The flow of liquid from the container 80 is controlled by a gate 100 which is actuated by a servomotor 94. The gate 100 is actuated to maintain the liquid level constant in accordance with the rise or fall of the liquid level, the circuit of the servomotor 94 being controlled by a float 86 carrying a contact 90 which operates with fixed contacts 92. Specification 207,664, [Class 69 (i), Hydraulic apparatus &c.], is referred to.

Abstract: 334,299. Soc. Italiana Pirelli, and Emanueli, L. June 11, 1929. Cable joints.-In connecting an oil-filled cable to a terminal, joint, &c., the end of the cable is closed temporarily to prevent escape of oil while the connections are being made, and the oil channel is then put into communication with an oil chamber in the terminal &c. A connector 5 is attached to the conductor 1 of the cable, the oil channel 2 communicating with the bore 13 of the connector, which is provided with means for retaining the oil while the wiped jonts 15, 15a axe made and while the oil chamber 12 in the insulator 7 is exhausted, and for subsequently opening communication between the channel 2 and the chamber 12. In one form a pipe 16, Fig. 3, fitted wth a stop-cock 17 is employed. Alternatively a rod may slide in the bore 13, Fig. 4 (not shown), and act as a valve to close or uncover a lateral hole in the connector leading directly from the bore 13 to the chamber 12. The rod is connected to a plug that closes the end of the bore 13, and may be removed after filling the chamber 12, a plain plug being substituted. A valve 23, Fig. 5, may shut off the channel 2 from the upper part 13<b> of the bore 13 from which a lateral hole 19 leads to the chamber 12. The valve is held closed by a wire 22 passed through openings in the wall and valve stem until the oil pressure in the channel 2 is sufficient to close it. After the cable is secured in the insulator 7, the chamber 12 is filled from a separate supply of oil, and the pressure in the chamber is then increased to cause the valve 23 to leave its seating, allowing permanent free communication. Specifications 255,033, 268,271, and 304,912 are referred to.
