Title: A new or improved fluid-pressure-responsive control valve of the sliding piston type
IPC: B66F9/18
Filed: 1945-11-15
Abstract: 621,974. Fluid-actuated valves. METAL VENTS, Ltd., and ZWICKY, J. F. Nov. 15, 1945, Nos. 33971/46 (divided out of 621,952) and 33972/46. [Class 135] In a multiway piston valve the piston is biassed by a spring or gravity to one end position and moved in the opposite direction by the pressure of actuating fluid, so as to take up definite positions corresponding to the fluid pressure. Fig. 1 shows a valve for the selective draining of three tanks connected to ports 7, 8, 9, the actuating pressure being applied through the port 4 and the piston formed with a draining duct 13. Fig. 3 shows a modification in which the pressure liquid is distributed through a central bore 18 and a radial bore communicating therewith to one of three ports 15, 16, 17 connected to tanks to be filled. In this case, rotation is imparted to the axially-moving piston by a ball 20 engaging a helical groove 19 in the surface of the piston. In another arrangement, the piston 9, Fig. 4, picks up weights 25, 26 as it moves. Fig. 5 shows a valve for use with a double-acting power piston cylinder, the opposite ends of which are connected to the valve ports 30, 31. Upon the application of low pressure to the port 4 the piston is moved so that the ports 30, 31 are connected via the duct 34 in the piston. Increase in the fluid pressure aligns the piston passages 33 with the port 30, so that pressure liquid passes to one end of the power cylinder, which liquid is forced from the opposite end to the port 31 and thence via the groove 31a in the valve casing to the exhaust port 32. In a modification, the valve is provided with an additional port, whereby pressure liquid may be applied to either end of the power cylinder. Specific applications of the valve of Fig. 5 and of the modification are described in Specification 621,952.

Title: Improvements relating to switch-operated electric lighting and signalling systems
IPC: G08B7/06
Filed: 1947-12-24
Abstract: 632,909. Protective cut-out arrangements. VICTOR PRODUCTS (WALLSEND), Ltd., and MANN, R. W. Dec. 24, 1947, No. 34247. [Class 38 (v)] [Also in Group XXXVIII] In an underground lighting and signalling system cornprising a number of lighting fittings connected together by cables with detachable couplings, and signalling switches arranged to control the lights, the switches are arranged in series in a low-voltage pilot circuit containing a relay or contactor, which interrupts the lighting circuit when the continuity of the pilot circuit is broken by operating a switch or by a fault. A further relay is provided to cause the interruption of the pilot and lighting circuits in the event of an earth fault on the lighting circuit, and the arrangement is such that the lighting circuit cannot be closed until all the couplings have been assembled. Fig. 1 shows one of a number of lighting fittings 35 with switches 42, supplied from a transformer 6 by means of a five-cored cable having cores 29, 30 energized by a centre-tapped. secondary winding 10, a core 31 connected to the core, 29 by a final coupling or shorting cap 47, a pilot line 32 and an earth continuity line or core 33, which is connected to the line 32 by the coupling 47. When the pilot circuit is complete the relay or contactor 8 is energized by a low voltage secondary winding 18 on the transformer 6, and closes its contacts 11 ... 14 to complete the circuit for the lamps 52. The opening of a switch 42 or the breakage of the pilot line 32 or earth line 33 de-energizes the relay 8 to open the lighting circuit. The centre-tapping of the winding 10 is connected to earth through the winding of a relay 9, which has its normally closed contacts 21, 22, 24 connected in series with the pilot circuit. Hence on the occurrence of an earth fault on the lines 29 ... 31, the relay 9 is energized and opens its contacts to interrupt the pilot circuit so causing contactor 8 to open the lighting circuit, the relay 9 being held open until reset manually, by a latch 54 which engages a detent 55 in the armature 25 of the relay.

Title: Improvements in or relating to the control of organs
IPC: G10B3/06
Filed: 1953-12-11
Abstract: 772,233. Organs. LAMBERT, S. E. March 9, 1955 [Dec. 11, 1953], No. 34498/53. Class 88 (2). Apparatus for selecting the combination of stops to be brought into operation by a combination piston comprises a plurality of switches, each switch being associated with a particular stop and each including an electrically conducting member 12 adapted to be moved between two fixed contacts 29 and 30 and to be retained in engagement with one or the other contact by a releasable latch 18, one contact 29 being connected to means for moving the associated stop to its operative position and the other contact 30 being connected to means for moving the stop to its inoperative position, and means controlled by the stop for shifting the associated conducting member 12, subject to release by the latch 18, from one contact to the other. The switches are arranged in rows and columns, each row being associated with a particular combination piston and each column with a particular stop. All the switches of a row have a common latch 18 and bus-bar 37. Each movable conducting member 12 consists of a flexible and resilient metal strip and each column of switches has two contact posts such as 27, one carrying the contacts 29 and the other carrying the contacts 30. The means for moving the conducting members 12 and the latches 18 may be either electro-pneumatic. Fig. 1, or electromagnetic, Fig. 13. With reference to Fig. 13, in order to set a particular combination of stops 61 to be operated by a combination piston 88, the required stops are first pulled out, energizing corresponding solenoids 45 to raise lifting rods 42 against the conducting strips 12. A setter piston 87 is then depressed, operating a change-over switch 77, followed by the combination piston 88 which completes a circuit for a solenoid 39. The latch 18 is thereby moved to its inoperative position so that the associated conducting strips 12 are free to move according to the positions of the lifting rods 42. Thus those strips 12 which correspond to stops in the " out " position are raised and are subsequently forced against their upper contacts 29 by the latch 18 when the combination piston 88 is released. Those strips 12 which correspond to stops in the " in " position are held against their lower contacts 30. The setter piston 87 is then released so that switch 77 returns to its original position as shown. Subsequent depression of the combination piston 88 causes a solenoid 57 to raise the associated strips 12 into contact with their bus-bar 37, energizing coils 65 of the selected stops and coils 66 of the others. The selected stops 61 are thereby held, or moved into, the " out " position, while the unwanted stops are held, or moved into, the " in " position. A similar process may be carried out in respect of each combination piston on the organ, independently of the other combination pistons. Specification 772,234 is referred to.
