Title: Improvements in or relating to controlling devices for low-pressure steam
Inventor: LIGHTOWLER LESLIE ERNEST
IPC: B61C1/00
Filed: 1950-03-03
Abstract: 675,325. Fluid-pressure servomotor-control systems. LAYCOCK ENGINEERING CO., Ltd. Dec. 29, 1950 [March 3, 1950], No. 5384/50. Class 135 [Also in Group XIII] A controlling device for low-pressure steam, e.g. to be supplied to a carriage-heating system from a locomotive, has a cast, gunmetal body 1 with internal chambers 12, 23 for a stop valve 18, Fig. 2, and a reducing valve, shown in Fig. 4, corresponding bosses 17, 32, 37B, for mounting and guiding their spindles 16, 37 and handwheels 20, 30. Furthermore, there are a high-pressure inlet 9, Fig. 2, and a lowpressure outlet 49, Fig. 5, a passage 10 from the inlet to the stop valve, a passage 22 from the stop valve 18 to the reducing valve, a passage 41 from the reducing valve to the outlet 49, and a boss 52 for a relief valve 54 making connection, Fig. 5, with the passage 41. The inlet 9 may be at the side of the body but as shown it is formed in a flanged portion 7 provided centrally at the back for mounting the body. The stop valve 18 co-acts with a seat 19 disposed between the valve inlet and outlet chambers 10 and 12 and also with an auxiliary seat at the inner end of a bush 14 so that a packing gland 15 may be replaced if necessary while the device is under pressure. The passage 22 from the stop valve outlet chamber 12 extends to the high-pressure chamber 23 of the reducing valve and a pressure gauge 4, Figs. 2, 3 is connected by a member 42 to the lower passage 41 from a low-pressure chamber 26 of the reducing valve. The passage 41 enlarges to form a chamber 48 surrounding a block 13 containing the stop valve chambers and returns as an upper passage 50 for communication with the relief valve 54. In modifications (not shown), the lower passage 41 connects to a relief valve projecting from the bottom of the body 1 and the upper passage 50 to the low-pressure gauge 4. A pipe 47, Fig. 3, threaded into the short tubular member 42 connects the gauge 4 to the passage 41 or 50 across which the member 42 is secured by a nut 44, communication being by axial and radial bore 45. In the reducing valve, Fig. 4, a throttling valve 24, in the high-pressure chamber 23, is controlled by an auxiliary valve 27 which adjusts the flow to a cylinder 35 and thereby the position of a piston 25 attached to the valve 24. The position of the valve 27 and thus the pressure of steam on the piston is determined by a diaphragm 28 acted on by steam on one side and a spring 29, adjusted by the handwheel 30, on the other. A fine bleed hole 39 connects the steam side of the diaphragm to the low-pressure chamber 26. A locking ring 40 secures the handwheel 30 in adjusted position. The relief valve 54 is spring-loaded, integral with a spindle 53 and has guiding fingers 57. When it is fully open, the surface 58, Fig. 3, of the valve bears against the bottom of an outer casing 51 which has radial slots to allow steam past the spindle to atmosphere by way of a union 59.

Filed: 1920-02-25
Abstract: 139,494. Pupin, M. 1. Feb. 4, 1918, [Convention date]. thermionic relays.- In the receiving circuit of a wave signalling system of the type employing a multi-step thermionic amplifier, the electric constants of the circuit are such that reaction between the tubes is destroyed with respect to internal disturbances but not with respect to desired wave signals. As shown in the diagram, two threestep thermionic amplifiers adapted for the reception of high frequency signaling waves are connected by an aperiodic pilot conductor which has this " filtering " property. The first amplifier consists of three interconnected high impedance tubes 1, 2, and 3, the plate circuit of the tube 3 being connected to the grid of an auxiliary low impedance tube 4, the function of which is to connect effectively the three-step amplifier to the pilot conductor. The plate resistances 7, 8, 9, and 21 are approximately equal to the respective internal impedances of the tubes 1, 2, 3, and 4. The aperiodic pilot conductor connects the plate circuit of the tube 4 to the grid of the first tube of the second multi-step amplifier and consists of a number of approximately equal capacities 22, 23, 24, and 25 connected in series and a number of approximately equal resistances 26, 27, 28, and 29 connected in parallel and earthed at 30. When lowimpedance tubes are employed in the amplifiers the capacities 22, 23 &c. are replaced by equal resistances and the resistances 26, 27 &c. are replaced by equal inductances. Any number of groups of valves may be connected in the manner described as circumstances may require.

Abstract: 482,014. Automatic exchange systems. SIEMENS BROS. & CO., Ltd., and VOSPER, W. T. Feb. 26, 1937, No. 5830. [Class 40 (iv)] In an outgoing repeater which sends break impulses over the outgoing loop, the latter is controlled by the impulse receiving relay A and by two auxiliary relays AA, AB at make contacts a1, aa3 in series and at a break contact ab4 in parallel with a1, the arrangement being such as to prevent the make and break periods being shorter than the permissible minimum. At each impulse, A, AA, AB fall back in succession and reoperate in the same order, so that the break period depends on, the release lag of AA, AB and the operating lag of AA and the make period depends on the operating lag of AB. Relay AB is made to operate more slowly than it releases by means of a winding normally shunted by a resistance YG, while the initial operating circuit includes a resistance YE which is cut out during impulsing. Upon seizure, the operation of A, AA, AB is followed by that of release relay B and switching relay HA, and dialling relay C pulls up at the first impulse of each train and holds by virtue of a short-circuited winding. Relay BB, which is connected up by C, energizes MD and is held between trains by the operation of I over the outgoing loop. The operation of polarized relay D and its auxiliary relay DD upon reply disconnects MD and places DA, DB under the control of S, Z pulse wires. During the period that these two relays are both energized, metering impulses are delivered to DC and are repeated over wire P. Relay I responds to busy flash, and its first relapse and reoperation connects up BR in place of BB whereupon the flash condition is repeated back by DD, the outgoing loop being maintained while A, AA are back by BR, which is held by DD.
