Abstract: 1476060 Rotary positive-displacement machines P R COSIER 5 Jan 1976 [18 Feb 1975 7 April 1975] 6705/75 and 14074/75 Heading F1F An engine driven by the thermal expansion of a liquid comprises pairs of inter-connected liquid filled chambers B1, B3 in which the chambers B1 are heated in sequence to displace liquid from their associated chambers B3, a rotary drive unit A1-A7. and a distributer valve C1-C3 for connecting each chamber B3 during the heating phase of its chamber B1 to an inlet A6 of the drive unit and to an outlet A7 from the unit during the cooling phase of its chamber B1. The drive unit comprises a member A8 rotatably mounted in a housing comprising a cylindrical casing A2 closed by end-plates A1, A3 and containing an arcuate member A10. Opposed pairs of vanes A11 connected by rods A9 slide in radial slots in the member A8. Liquid supplied to the inlet A6 enters a chamber A12 defined between the member A10 and that vane A11 which is in sealing contact with the casing A2. The liquid expands the chamber A12 to cause relative rotation between the casing A2 and the member A8. Once the vane A11 passes a circumferential slot in the arcuate member A10 leading to the outlet A7 the driving liquid is exhausted into the chambers B3 of the unheated chambers B1, the succeeding vane A11 having then seated against the casing A2. Each chamber B 1 is filled with an easily expandable liquid such as acetone and each chamber B3 is filled with oil, expansion of liquid in the chamber B3 acting via a rod (B13) slidable in a barrel B2 to move a piston (B10) and displace the oil from the cylinder B3.

Title: Improvements in and relating to closed liquid circulating systems
IPC: F24F5/00
Filed: 1962-02-19
Abstract: 945,624. Heating and cooling systems. G. S. MINICH. Feb. 19, 1962 [Feb. 17, 1961], No. 6822/62. Heading F4U. [Also in Division F1] In a heating or cooling system utilizing a circulating liquid, a liquid-vapour emulsion or a liquid containing a gas or solid material, a fluid transfer device is provided between zones of differing pressure (due for example, to differences in elevation in a space heating or cooling installation), the device acting to counterbalance the liquid pressure in the flow and return lines of the zone and at the same time permitting the flow of liquid from one zone to another. The system shown for cooling a mine includes a pump 9, a heat exchanger 10 in which the circulating liquid is cooled and which may comprise the evaporator of a refrigerating system, a heat exchanger 11 in which the circulating liquid cools air passing to the mine. The fluid transfer device includes chambers 3, 6 separated by a flexible diaphragm 2, one-way valves 4, 5 and control valves 7, 8. With the valves 7, 8 in the position shown, movement of diaphragm 3 to the left draws fluid from zone A into chamber 6 and replaces it by fluid from chamber 3. Valves 7 and 8 are now actuated so that valve 7 is closed and valve 8 opened. Movement of diaphragm 2 to the right will now force fluid from chamber 6 into zone B of the circuit and at the same time fluid from that zone will be drawn into chamber 3. Hence movement of valves 7 and 8 and diaphragm causes fluid to be circulated from one zone to the other and thus through the system. The fluid transfer device may serve also as a pump, the pump 9 then being omitted. In practice the system comprises several of the zones served by a plurality of the transmitting devices connected in series or in parallel to provide a continuous circulation of the fluid. In a space heating system described (Fig. 2, not shown) the fluid transfer device comprises a piston, the return movement of which is acuated by a spring, the fluid control valves being controlled by solenoids and an electrical timing mechanism.

Title: Improvements in Railway Signalling.
IPC: B61L3/02
Filed: 1919-03-19
Abstract: 135,743. Sykes Interlocking Signal Co., W. R., and Tiddeman, E. S. March 19, 1919. Track apparatus actuating signals on trains and for stopping trains. - In apparatus of the kind in which signals or train-stopping apparatus are actuated mechanically unless an electro-magnetic restraint is brought into operation by contact of a shoe or plunger carried on the train with a ramp which is arranged to move said shoe or plunger and also to form with it a part of an electric circuit controlled by the signals or otherwise according to the condition of the traffic, such as is described in Specification 6499/15 and 112,191, the ramp is provided with insulated sections of conductors, which are respectively engaged first by the shoe, according as the train moves forwards or backwards As shown, the circuits are controlled by contacts on the signal lever; but these may be on the signal itself, or a separate switch may be provided. In normal running in the direction of the arrow A at a clear signal, positive current passes from the battery 21 over contacts 23 to the ramp 14 and the train apparatus, which includes a non- polarized brake magnet and a polarized relay controlling a bell which is sounded when positive current is received. The circuit to the ramp extension 12 is open, but this part of the ramp is of insufficient height to apply the brakes by the consequent mechanical action. On passing a danger signal in the normal direction, the train receives no current from the ramp 14, and the brakes are accordingly applied. At the ramp 12, negative current is received and the bell is restrained. A train backing past a signal receives negative current from the ramp 12, and this circuit includes the coil 37 of the relay 33, which closes the contact 39, and thus the train receives negative current also from the ramp 14 to restrain the application of the brakes and keep the bell silent. The circuit from the ramp 14 includes the coil 38 of the relay 33, which maintains the circuit made by the temporary energization of the coil 37.

[Class 103 (v)] In a balanced double buffer for railway &c. vehicles, i.e. one in which the pressures on the buffers are transmitted from one to the other under running conditions and particularly on curves, and in which a damping device is incorporated for equalizing the thrusts under buffing shocks, the equalizing means comprises a body of fluid contained in two cylinders 8 freely communicating with each other by a conduit 7 and in each of which works a piston 3 or 4 directly connected to one of the buffers 1 or 2. As shown in the Figure, the chambers 8 and conduit 7 contain a liquid and are located at the rear of the pistons 3, 4, while the damping device consists of an additional cylinder 10 containing a spring- pressed piston 11 and communicating with the conduit 7 by means of a valve 13 having a small central passage 14. Under buffing shocks the valve 13 opens, and liquid passes freely into the channel 9 to force the piston inwardly ; during recoil, the valve 13 closes and the liquid is restored slowly to the conduit 7 through the passage 14. In a modification, the chambers in front of the pistons 3, 4 are in free communication and contain liquid, while the chambers to the rear also communicate to form an air clamping cushion. In another modification, in which the communicating chambers at the rear of the pistons contain air, a third cylinder containing a piston opens on to the conduit, and the latter piston is fitted with a central draw hook. According to the Specification as open to inspection under Sect. 91, springs may be incorporated in the buffer cylinders to assist in restoring them to a normal position. This subject-matter does not appear in the Specification as accepted.

Abstract: 770,630. Supply meters. PHILIPS ELECTRICAL INDUSTRIES, Ltd. March 11, 1955 [March 13, 1954], No. 7222/55. Class 37. In a meter having a rotor with a vertical spindle 1, Fig. 1, the rotor is supported at its lower end by a radially self-centring magnetic thrust bearing 3, 4 with end stop 7, the rotor and associated bearing being enclosed in an insulating aid partly evacuated housing 11, 12. The upper end of the spindle has a point 5 co-operating with a cup 6 and carries a disc 2 having an aperture 8. Electrodes 9, 10 are arranged so that the aperture 8 passes between them to allow a discharge to take place and operate a counting mechanism, the disc 2 being of aluminium covered with an oxide layer. The housing 11, 12 is evacuated and filled with inert gas or mercury vapour. The outer surfaces of the rotor 3 of the magnetic bearing and the inner surface of the stator are conical and magnetized in a radial sense in such a way that the poles of the same polarity are adjacent each other. In a modification, Fig. 3, the disc 2 is arranged with its centre of curvature at the point 5, the drive coil 18 and brake magnet being arranged so that the flux passes through the disc. The disc is covered with an insulating material except opposite the electrode 9 where a molybdenum plate 15 is attached to the disc. Discharge takes place between the electrode 9, the plate 15, the end of the spindle 1 and the electrode 10. In a further modification, Fig. 4, the disc 2 is made hemispherical, with voltage and current coils 17, 19 arranged outside the housing 12 with a ferro-magnetic strip 18 surrounding the housing so that the flux passes through the disc. A brake magnet 21 is arranged around the upper part of the disc the magnetic flux paths being completed by the use of a strip 20 within the housing. This is mounted on a tube 26 which also supports the upper cup 6. The magnetic bearing comprises two parts 3, 4 magnetized in the same sense. The electrodes 9, 10 are connected in circuit with a coil 22, Fig. 5, and ratchet and pawl device 23 to operate a counter 24. When the current through coil 19 ceases, the disc 2 continues to rotate until the discharge between the electrodes 9, 10 ceases. A capacitor may be included in the voltage winding, Fig. 6 (not shown). By making the electrode 9 pointed and electrode 10 flat a rectifying effect can be obtained, and the potential from the mains may be adjusted by the use of an auto-transformer or potentiometer. A tapping may also be made on the voltage coil 17. Continuity of the ionization may be maintained through an auxiliary anode and a high valued resistor, or a radio-active source. Specification 770,629, [Group XXXIV], is referred to.
