Title: Improvements in pressure reducing valves
Inventor: JAY JAMES BERTRAM
IPC: G05D16/06
Filed: 1953-05-18
Abstract: 723,258. Valves. HYMATIC ENGINEERING CO., Ltd. May 18, 1953 [May 19, 1952], No. 12580/52. Class 135. A pressure reducing valve comprises a coaxial double-beat valve actuated by a bellows d subject internally to inlet pressure and externally to delivery pressure. The double-beat valve comprises a hollow stem a on which are sealingly mounted a sleeve g carrying a seating- ring h, one or more Belleville springs j, a coned and splined spacer sleeve i and a sleeve k carrying a seating ring m. By turning a nut n, locked by a spring r engaging stem notches b, the position of the seating rings can be adjusted relatively to one another and the seats e, c. Fluid flows from the inlet s, through ports u in a seat carrying unit c<SP>1</SP> secured in the valve casing by a nut y locked by a spring 10, through the seat e where it is metered by the coned part h<SP>1</SP> on the stem and the seat c where it is metered by the coned part i and through the hollow stem and openings f to the outlet w. The stem has flats 16 which, when the valve is open, provide a fluid passage around the stem and through the bottom 13 of the seat unit to the space 14 to augment the effect of outlet pressure on the bellows which normally acts past an adjustable needle valve. The stem is connected to the bellows by a rubber collar 24 to prevent the transmission of bellows vibration and the bellows, which may be internally spring-loaded to expand it, is supported on an adjustable ball joint 18. The space 14 may be connected by a pipe to the unit supplied with fluid from the outlet w, in which case the needle valve acts to damp out vibrations. The seats may be of equal cross-section in which case the valve is balanced. If the lower seat is of larger area so that inlet pressure tends to close the valve, the seat unit is made of two parts spigoting together.

Title: Improvements relating to a stopping device for use on draw-twisting machines
IPC: B65H63/028
Filed: 1966-03-22
Abstract: 1,132,742. Stop-motion. BARMAG BARMER MASCHINENFABRIK, A.G. 22 March, 1966 [23 March, 1965], No. 12610/66. Heading D1D. In a stop-motion on a draw-twisting machine which is actuated in the event of a lap on a godet or on its associated guide roller, comprises a feeler-unit arranged beside yarnbearing surfaces of the godet and roller; the unit is in the form of two flanges rotatably mounted on a spindle and either the edge or the face, in the case of each flange, act as the feeling element, while the two feeling elements are disposed at equal distances from the godet and the roller; further, the plate carries a control member which when a flange is moved by a lap actuates the device for stopping the machine. Plates 7, 8 are in one with a sleeve 6 around a shaft 5 secured to a fixed part 4. When a face is to be used as a feeling element, the latter is so disposed that it lies parallel to a tangent to the associated yarn-bearing surface; when the edge is to be used as the element, the flange is so disposed that it would cut the associated surface if produced. To take care of the mutual inclination of the axes of the godet and roller, one edge is inclined, or one plate is appropriately twisted. The device is so disposed that the flanges lie within the area enclosed by the yarn between the godet and roller. When a lap builds up it engages the corresponding flange and rotates the sleeve 6 to which a member 9 is adjustably secured, so that the member engages a microswitch 12. The member 9 may have a hand grip or be moved by a separate lever when it is desired to stop the machine manually.

Abstract: 1537550 Activation analysis KERNFORSCHUNGSZENTRUM KARLSRUHE GmbH 29 March 1976 [29 March 1975 12 April 1975] 12614/76 Heading G1A [Also in Division G6]  Apparatus for analyzing fluent material in intermittent sequence comprises: a dosing vessel 8 Fig. 1 having an inlet 14 and outlet 16 for forming a sample; a radiation vessel 9 having an inlet 15  and outlet 17 and containing a radiation source 41 positioned to activate uniformly a sample admitted to the vessel 9; a measuring vessel 10 Fig. 2 having an inlet 95 and outlet 99 and containing a radiation detector 11; and material guide means combining the dosing, radiation and measuring vessels into a structural unit 1. Outer guide tubes 2-7 containing shielding and moderating material e.g. graphite 49, 50, 51, 68, 69 and lead 62, 63, 64, 65, 70, define passages alternately annular and tubular in cross-section and inter-connected by funnel-shaped cavities 71, 74, 75, for screening the vessels 8, 9, 10 from each other and for guiding the sample from one to the other. Hot moulding sand, to be analyzed for residual bentonite, is placed in a hopper 110 whence it is admitted to a spherical dosing vessel 8 via a pivotable shutter in the form of a spherical cap 83 driven by a motor 87. The volume of sand defined between the vessel 8 and a spherical insert 18 is released into the spherical radiation vessel 9 by a shutter 26 driven by a motor 38, where it is activated for a predetermined time with thermal neutrons derived from a source 41. This is a Cf-252 pellet of 54 mCi activity, having a triple Cf 2 O 3 - cermet encapsulation, and is screwed from the side into a 7-ray absorbing iron core 40 surrounded by an inner sphere 19 containing powdered ZrH 2  moderator 43. The moderator 43 thermalizes the fast neutrons and so prevents them from activating the silicon of the sand itself. The thermal neutrons produce Al-28 in the bentonite, having a γ energy of 1À78 MeV with a half-life of 2À3 min. After a predetermined irradiation period the sand is released by a shutter 27 driven by a motor 39 into the measuring vessel 10 having a hemispherical and a cylindrical portion 94, 96, where γ-rays are received by the detector 11 including a NaI(Tl) crystal. A measuring system (not shown) includes a high voltage unit, an amplifier, a stabilizer, an analyzer and a counter-timer for controlling the motors 87, 38, 39 and counting pulses representing Al-28 activity, and a power pack. The detector 11 is protected by a water cooling system 107. The structure 1 on a frame 109, is shielded (not shown) with elements of graphite and of paraffin wax containing boric acid additive.

Abstract: 1457965 Cutting by fusion H G BALS 26 March 1974 [27 March 1973] 13344/74 Heading B3V  An electrically conductive workpiece 34 is cut by applying an intermittent voltage betweeen it and a rotating endless electrode 14 to generate an arc to seften and/or melt the workpiece 34 and oscillating the electrode 14 in the cutting direction so as to remove the softened and/or molten material from the workpiece 34 while the voltage is zero. An endless wire electrode 14 is mounted on two pulleys 10, 12, one of which 12 is driven by a motor 16 to rotate the electrode 14, e.g. at 100 m./sec. The pulleys 10, 12 are provided with radial cooling bores (20) (Fig. 2, not shown) and are mounted together with guide rollers 30, 32 on a frame 26 which is pivotable about a spindle 44. The pulley 12 and the motor 16 are mounted on a floating bracket 18 which maintains the wire 14 taut. The guide rollers 30, 32 are eccentrically mounted so that when they are rotated in synchronism, the electrode 14 is horizontally oscillated at an amplitude of 1 mm. causing the softened and/or molten material to be mechanically removed. The voltage applied between the electrode 14 and the workpiece 34 is interrupted during the time of contact of the electrode 14 with the workpiece 34 which is moved relative to the electrode 14 over a work-table 24 having a non- conducting layer 28 for insulating it relative to the frame 26. A compressed air jet (42) (Fig. 3, not shown) is blown on to the rear side of the electrode 14 in the cutting region to prevent the generated arc from completely encirculing the electrode 14. The electrode 14 may alternatively be in the form of a steel band having a leading edge with sawtooth projections and an insulated rear edge.
