Abstract: 718,964. Filing papers; bookbinding. NATIONAL BLANK BOOK CO. Jan. 19, 1953. No. 1520/53. Classes 16 and 146(1) A binder cover construction comprises a back portion having two flexible sheets 3. 4 of plastic material and a stiffener strip 5 of smaller area laminated between them, spaced pins 6 mounted in the strip and extending through one sheet for fastening a sheet binder device such as a ring binder 15 thereto, two covers 1, 2 of plastic material with the inner marginal side edge of each cover located between the outermost edge portions 12, 13 of the side margins of the flexible, material and welded therewith in laminated form, the covers being thinned down along the marginal weld 12<SP>1</SP> and the end edges of the back, being flush with the cover edges. Hinge bands 10 and 11 are made by welding sheets 3 and 4 either side of the strip 5, leaving an unwelded flexible band 16 between welds 10, 11 and 12<SP>1</SP> and the sheets are also welded along bands 14 at each end. In a modification, the hinge band welds 10, 11 are omitted, the strip 5 extending nearly up the bands 12<SP>1</SP> and the sheets 3, 4 acting as the hinge.

Title: Nuclear reactor containment

Filed: 1974-01-11
Abstract: 1443301 Bolting SIEMPELKAMP GIESSEREI KG 11 Jan 1974 [13 Feb 1973] 1531/74 Heading F2H [Also in Division G6] The cover 5 of a missile shield surrounding a nuclear reactor pressure vessel and made up of cast iron segments clamped together by axial and circumferential tension elements 7, 8 is removable after releasing a plurality of fastening means 25 which, when released, still retain the remaining parts of the shield in a clamped condition. The axial tension elements 7, of steel rope or bar, pass through sleeves 23 in bores 15 of the cover 5, the tops of the sleeves projecting above the cover to form collars 24. A respective externally threaded anchor plate 26 secured to the top of each tension element 7 has a smaller external diameter than the diameter of the bore 15, and receives a nut 27 to clamp the cover 5 via split spacers 28. To remove the cover, the anchor plates 26 and nuts 27 are raised by a press (not shown) the spacers 28 are removed laterally, and the anchor plates and nuts lowered until the plates 26 rest on their collars 24 to allow the tension of the elements 7 to compress the sleeves 23, and hence the parts of the shield below the cover, to clamp them together. The nuts 27 are then removed, and the cover 5 lifted off.

Abstract: 1,088,401. Regulating fluid flow. DI-DRO ENGINEERING CO. Jan. 13, 1966, No. 1653/66. Heading G3H. [Also in Division F2] A metering valve controlling the flow between two passages 62, 64 at right angles to each other comprises a cylindrical valve member 72 which is a close slip fit in a bore 70. An axial passage 90 in the member 72 is in constant communication with passage 62 and a radial passage 94 leads from the axial passage to a V-shaped circumferential groove 96. The width of the groove 96 tapers from the passage 94 for 180‹ on both sides of the passage. The angular position of the valve member is adjusted by removing a plug 74. The metering valve is described for use in a valve controlling flow of fluid to a press cylinder in which a supply (16) Fig. 1 (not shown), feeds through a non-return valve (26) to the cylinder and the cylinder pressure acts through passages (64), (60), grooves (54), (50) and passage (48) to close a valve (32) at a predetermined pressure. When the pressure cylinder falls, the pressure acting on the end of cylinder (46) leaks through the metering valve to allow the spring (36) to open the valve (32).

Patent GB-1123485-A (GB)
Title: Superregenerative null detector
IPC: G01R19/00
Filed: 1966-01-14
Abstract: 1,123,485. Amplifying circuits. ROSEMOUNT ENG. CO. 14 Jan., 1966 [14 Jan., 1965], No. 1955/66. Heading H3W. [Also in Division G1] A null detector for detecting the presence of a unidirectional input signal on an input line 16 comprises an amplifier 18 with positive feedback on line 25 such as to make the amplifier superregenerative i.e. in a state where the positive regenerative feedback is in excess of that required to produce an essentially unlimited gain. Feedback is periodically interrupted by closing a switch 33 to ground the feedback loop and thus restore amplifier 18 to a stable state in which its output is zero and can be changed in either direction by a small input signal voltage applied across terminals 11, 12, the direction of charge of output depending on the polarity of the input. When switch 33 is closed a small unidirectional signal voltage charges capacitor 32 and when switch 33 is opened a fraction of the input voltage is applied to amplifier 18 through a capacitor 17. A capacitor 28 will then be charged by the amplifier output in the same direction as the polarity of the input signal and a positive feedback signal is applied to the amplifier input over capacitance 26. The amplifier output will increase as a generally exponential function of time until amplifier 18 saturates Fig. 4 (not shown). The polarity of the output of the amplifier and hence of the input signal may be observed on a voltmeter 22. Switch 33 may be automatically opened and closed at a desired rate to provide a continuing indication. In a modification, Fig. 3 (not shown), low frequency circuit oscillation is prevented by non-linear elements each comprising e.g. Zener diodes connected in series opposition so as to conduct at voltages above some particular value. If a suitable non-linear element (106) is placed in series with the output meter, the latter will receive current only when the amplifier is saturated. The average meter reading will then be an indication of the amount of time for which the amplifier is saturated. This time is proportional to the logarithm of the input voltage signal over a wide dynamic range, Fig. 4 (not shown). The null signal detector may be arranged for detecting the output from a bridge circuit, Fig. 5. A switch 151 for periodically interrupting the feedback is operated at a uniform repetitive rate and synchronously with a switch 128 for simultaneously interrupting a power supply 127 to the bridge circuit. The amplifier 134 is an A.C. amplifier having a bandwidth extended below the feedback interruption repetition rate.

Title: Improvements relating to non-return valves
Inventor: BOWERS ERIC HIDER
IPC: F16K15/06
Filed: 1952-01-29
Abstract: 709,847. Fluid-actuated valves. DOWTY EQUIPMENT, Ltd. Jan. 29, 1952, No. 2429/52. Class 135. [Also in Group XXVIII] A non-return valve, particularly for use in the delivery conduit from a multi-cylinder hydraulic pump, to allow pressure waves to be transmitted through the valve without excessive build-up of pressure at the valve outlet, comprises a body 21 having an inlet 22 and outlet 25, a piston 31 movable in the body and exposed on opposite sides to the inlet and outlet, a valve closure member 28 formed by the piston or a part associated therewith and normally closing the inlet under the spring 36, the piston being permitted too-and-fro movement under inlet pressure pulsations when a predetermined outlet pressure is reached without opening the inlet. Liquid passes from the pump through the inlet 22 and raises an annulus 28 from a seat 29 against the spring 36 which is oppositely seated on radial arms 33 of the piston 31 sliding through the annulus. The arms normally abut a casing shoulder 34. The liquid leaves the outlet 25 and passes through a selector valve to a jack which, 'when its movement is completed, allows the annulus to seat. Cyclical pressure waves from the pump will now cause the annulus to oscillate and entrap small increments of pressure on the outlet side until the excess pressure is sufficient to move the piston arms 33 away from the shoulder 34, in which condition the waves are transmitted by the piston to be dissipated in the outlet part of the hydraulic circuit. Small excess pressure developed at the outlet may also be dissipated by leakage between the annulus and the piston, but reverse flow is prevented by the piston shoulder 38 engaging the sealing ring 37. In a modification a hollow ported piston slides in an inlet opening. Flow to the jack opens the ports by making the piston compress a spring, after which the ports just close and the spring is unstressed. A pump pressure wave momentarily opens the ports and builds up an excess pressure on the outlet side which moves the piston further into the inlet opening against spring tension, in which condition the piston transmits the pressure waves.
