Filed: 1938-08-08
Abstract: 520,992. Valves. HURST, W. F. F. MARTIN-, and BRITISH THERMOSTAT CO., Ltd. Aug. 8, 1938, Nos. 23376/38 and 10497/39. [Class 135] A valve-device particularly for the cooling- system of aircraft engines comprises a valvemember which can open in opposition to a thermally-sensitive chamber to relieve excessive pressure, and co-operates with a movable valve-' seat for admitting air to the system when the pressure falls. The valve shown in the Figure is enclosed in a casing 1, 2 which communicates through openings A, 3 with the cooling-system and an air-outlet pipe. A valve-disc 10 cooperates with a seat 8 on a disc 7 carried by a bellows 4 which is mounted in a holder 5 provided with a stop-ring 9 for the bellows. The valve-disc carries another bellows 13 provided with a cup 14 having a threaded stem 15 carrying a sleeve 16 which can slide in a threaded bush 17 in the casing. The bellows communicates with a phial 11 which is attached to the valvedisc and passes through a guide 12. The phial is heated by the system and contains the same liquid as that in the system, or contains a liquid having a slightly higher or lower boiling point than that in the system. A spring 23 is arranged between tne cup 14 and a collar 24 which abuts on a flange 25 on the sleeve 16. Another spring 22 is arranged between the casing and a hood 20 attached to the valve-disc. When the system warms . up, the valve-disc is opened in opposition to the spring 22 to allow escape of air, and when the collar 24 abuts on the bush 17, the pressure in the bellows 13 aids the spring to close the valve-disc. When the maximum pressure is exceeded, the spring 23 yields and the valve acts as a safetyvalve. When the system cools, the bellows 4 yields and the valve-disc opens to admit air into the system.

Abstract: 940,487. Analysis of X-ray and other spectra. T. I. (GROUP SERVICES) Ltd. June 27,1962 [ June 29,1961], No. 23511/61. Heading G1A. In a method of testing material to determine its constituents, the material D, Fig. 3, is bombarded with electrons and the resulting radiation (X, y or infra-red) is detected by a proportional counter C whose output is applied through an amplifier A to a pulse height analyser P which sweeps through the amplitude range in half a volt steps and produces a count at each step. To enable reasonable accuracy, the sweep extends over a period of two to four minutes. The resulting signals, which represent the energy spectrum in the fashion shown in Fig. 2 and where the X coordinate is denoted by time, are applied to a ratemeter R the signal from which modulates a carrier signal at M. The final signal is then applied to record on one track of a multi-track magnetic tape recorder TR, the start of movement of the tape being synchronized with the start of sweep in gate P by a signal S. The procedure is then repeated with known pure elements in place of the sample, the elements being those known to be or suspected to be present in the sample. The resulting energy spectrum signals are recorded in similar fashion on further tracks 2-4. The recorded signals are then all played back simultaneously, Fig. 4, and applied through amplifying and detecting channels A', F to control a doublebeam oscilloscope DB. The signal from track 1 corresponding to the sample is applied to the Y-deflection plates of one beam,whilst the signal from tracks 2-4 corresponding to known elements are fed through individual adjustable attenuators V and a combining unit B to the Y-deflection plates of the other beam. The X-plate deflection is synchronized by a signal from the magnetic recorder, the tape in which is formed into a closed loop and run through repeatedly at a rate, say, thirty times greater than the recording rate. The oscilloscope has sufficient persistence to keep the whole of the two traces visible and the three attenuators V are adjusted until the trace from combining unit B matches that due to the sample. From the settings of the control knobs of attenuators V, the proportions of the known elements in the sample may be deduced. In ah alternative arrangement instead of using a double-beam oscilloscope, a single beam tube is employed, the sample signal being applied to one Y-deflection plate, the signal from combining unit B being applied to the other Y-deflection plate and the attenuators V being adjusted to obtain a straight line trace. A storage oscilloscope may be used.

Title: Pressure relief valves and packaging containers incorporating them
IPC: B65D77/22
Filed: 1977-06-03
Abstract: Between the container wall (1) and the covering (6) which covers a passage opening (2), a valve element (3) is fixed by an edge-side layer of adhesive or a weld (4). The valve element (3) consists of a porous, disc-like material impregnated with a liquid. The valve element (3) advantageously serves as a carrier for the liquid. The valve opens by the liquid layer in the pores of the porous material tearing open in the event of overpressure. In this overpressure valve which already responds at very slight overpressures, the risk of gas exchange into the interior of the packaging container occurring in the interval between the diminishing of the overpressure is reduced. <IMAGE>

Abstract: 723,833. Lubricating systems. SIELAFF, M. [trading as VOGEL KOMMANDIT-GES. W.]. Sept. 23, 1952 [Dec. 3, 1951], No. 23827/52. Class 12 (3) In a system for the automatic lubrication of machines in which lubricant from a supply reservoir is fed under pressure through a conduit common both to one or more points to be lubricated continuously and to means for feeding the lubrication points intermittently, a pressure responsive flow-controlling valve is interposed between the common conduit and the points to be continuously lubricated, so as to ensure sufficient pressure for the intermittent lubricant, and passages for returning excess lubricant to the supply reservoir are provided both on the continuously-operating and the intermittentlyoperating devices. In the arrangement shown, lubricant is supplied from a reservoir 1 by a pump 2 to a conduit 5 leading by a spring-loaded valve 3 to points 4 to be continuously lubricated. Excess lubricant returns to the reservoir by a conduit 6. A conduit 7 connected to the conduit 5 leads to a housing 8 in which is a control piston 9 provided with an annular groove 10. When the piston is actuated, which may be done mechanically, hydraulically, or electro-magnetically, the piston moves inwardly, opening communication between the conduit 7 and a conduit 11 leading to distributers 12 for 'supplying points with accurately dosed quantities of lubricant. Lubricant returns from the conduit 11 to the housing 8 through a spring-loaded valve 14, which is set for a lower pressure than that of valve 3. Lubricant flowing through the valve 14 forces the piston 9 back to its normal position, in which excess lubricant in conduit 11 flows back to the oil reservoir 1. The bore 15 at the inner end of the piston is connected through a valve 18 and a passage 19 with the return passage 17 to the reservoir. The valve 18 responds to a small pressure sufficient for returning the piston to its normal position. A catch 20 is provided to locate the piston resiliently in its operative and normal positions.
