Patent GB-381849-A (GB)
Title: Improvements in and relating to pressure gauges
IPC: G01L19/06
Filed: 1932-03-22
Abstract: 381,849. Pressure gauges. JUNKERS, H., 21, Kaiserplatz, Dessau, Anhalt, Germany. March 22, 1932, No. 8513. Convention date, March 23, 1931. [Class 106 (ii).] A gauge more especially of the floating bell type wherein a valve is automatically operated to shut off the admission of pressure fluid to the measuring chamber at excessive pressures is provided with an automatic device between the admission pipe and the measuring chamber which enables the pressures in the pipe and measuring chamber to balance in spite of the valve being closed when the pressure in the admission pipe again falls to a point within the range of the apparatus. The liquid chamber 1 communicates with the atmosphere through an opening 2 and houses a floating bell 4 which is guided on a rail 3. A pipe 5 admitting pressure fluid to the bell above the level of the sealing liquid has mounted on the end a valve casing 6 housing a valve 7 provided with a stem 8 and also a non-return valve formed by an elastic disc 11 which bulges slightly on the side facing the pipe and is provided with a slot 12. Normally, when the pressure is the same on both sides of the disc, the natural elasticity of the disc keeps the slot 12 closed. As the pressure increases the bell rises and when at the end of the range, a projection 9 engages the stem 8 of the valve 7 and shuts off the supply. When the pressure of the supply fluid falls below that within the bell the valve 11 bulges further causing the slot 12 to open and equalize the pressures. As the pressure falls again within the range, the bell descends and the valve 7 takes up the original position. The device may be fitted to a diaphragm gauge, the parts 6, 7, 8, 10, 12 being built into the pressure chamber of the diaphragm housing and the spindle 8 being connected to the diaphragm so that the valve 7 is seated when the deflection of the diaphragm is at a maximum.

[Also in Group XL (b)] A high-frequency electric discharge device having a high-frequency coaxial line connector sealed through insulating material forming part of the envelope of the device is coupled to an external coaxial line feeder through the intermediary of an external cavity resonator rigidly fixed to the envelope of the device in order to prevent damage to the insulating seal due to vibration of the feeder. The cavity resonator also acts as an impedance matching device. In the magnetron device shown, 10, 16 is the coaxial line connector, 15 is the insulating seal and 31 the cavity resonator which is tunable by means of the slug 35. The external feeder is connected to the cavity resonator 31 at 33. The inner conductor 16 of the coaxial line connector 10, 16 terminates in a probe 17. The magnetron is of the multi-cavity vane type, double strapped at each end of the anode block and with packaged polepieces. The magnetron envelope 1 and external magnet structure 23, 25 is embedded in silicone rubber 29 within a protective casing 27. The rubber 29 is injected into the casing 27 through the opening 28 which is plugged with thermosetting resin loaded with silica flour 30. The discharge device may have more than one high-frequency connector and may be associated with more than one cavity resonator, e.g. where the discharge device is an amplifier.

Filed: 1940-05-15
Abstract: 540,863. Electric signalling and controlling. BUSH RADIO, Ltd., HARRISON, W. H., and FLETCHER, H. L. May 15, 1940, No. 8703. [Class 40 (i)] [Also in Group XL] An electric signalling or controlling apparatus comprises a circuit adapted to receive alternating currents, means for rectifying said currents, means for storing electrical energy obtained by the rectification of said currents, and means for discharging the accumulated electrical energy through current responsive means to initiate a signalling or controlling function. Fig. 2 shows an arrangement in which a carrier wave modulated by a constant low frequency current is received at terminals 10 and is arranged to energize a signalling device 20. The input is applied to a tuned circuit LC the output of which passes to a dry rectifier 12 and then to a resonant circuit 13 tuned to the modulation frequency. The inductance of circuit 13 comprises the primary of a step-up transformer which applies the low-frequency voltage to a dry rectifier 15 supplying a large storage condenser 16. A time switch 18 periodically discharges condenser 17 to supply a large impulse for operating a relay 17 controlling the signalling device 20. A simpler circuit is also described for operation by an unmodulated alternating current, there being in this case only one dry rectifier. The arrangement may be used for switching on a wireless receiving apparatus.

Title: Improvements in method of making inflatable articles of liquid-impervious material lined with fabric
IPC: B63B7/08
Filed: 1953-03-31
Abstract: 725,986. Compound sheet materials. UNITED STATES RUBBER CO. March 31, 1953 [June 24, 1952], No. 8858/53. Class 140. [Also in Groups I and XXXIII] Inflatable fabric-lined articles are made by folding a sturdy fabric upon itself, stitching the folds to form a flattened sleeve, applying adhesive to the outer faces of the sleeve and finally applying a sheet of liquid impervious material to each side of the flat sleeve forming flange joints with each other beyond the edges of the fabric. The sleeve may be stitched also in spaced apart seams to form a plurality of tubes intercommunicating through the stitches. The ends of the fabric may be sewed together to form a closed loop before forming the tubes. Boats, paddling pools, inflatable mattresses and other inflatable articles may be thus produced. If desired the tubular construction may be varied at different points by interrupting the sewing operation. As shown, an inflatable wading pool is constructed by forming a piece of duck 10 into a loop by sewing its ends with nylon thread and folding the loop upon itself lengthwise at the middle 14 to form a double-ply fabric. The edges 15 are joined by stitches 16 and the required tubular construction formed by further parallel rows of stitching 17. The fabric is then coated with cement (or it may have been coated previously, if desired) and sheets 18 of rubber, neoprene gum or other liquid impervious material applied to each side, forming flange joints 19 with each other at the top and bottom. A base sheet 20 is then applied over one of these flange joints and an inflating air valve 21 attached to complete the structure.

Abstract: 793,398. Smokeless powder compositions. OLIN MATHIESON CHEMICAL CORPORATION. March 22, 1956 [May 17, 1955], No. 8956/56. Class 9(2) The invention comprises smokeless powder grains having a coating of a di-isoalklphthalate having from 3 to 6 carbon atoms in the alkyl group. Suitable smokeless powders are those with a nitrocellulose base or those containing a liquid explosive ester (e.g. nitroglycerin) in combination with nitrocellulose or nitrostarch. The diisoalkylphthalate should be used in amounts of between 2 and 15 per cent. The deterrent may be applied to the grains for example by suspending the grams in an emulsion of the di-isoalkylphthalate in water using gum arabic as emulsifying agent. In an example spherical grains of gelatinized nitrocellulose coated with about 15 per cent of nitroglycerin were coated with about 4 per cent diisobutylphthalate by emulsion coating.
