Title: Improvements in fluid flow control valves
Inventor: KLINGER-LOHR HUBERT DR
IPC: F16K3/24
Filed: 1961-02-07
Abstract: 915,063. Valves. ISTAG A.G. Feb. 7, 1961 [Feb. 12, 1960], No. 4570/61. Class 135. A fluid-flow control valve comprises a sealing ring closure member 2 carried by a part 1 on a two-part piston member 1, 11, the other part 11 being loosely mounted on a spindle 5 and loaded by a spring 10 into engagement with the sealing ring. The part 1 is allowed limited axial movement relative to the spindle such movement being determined by a collar 7 on the spindle. To close then valve the piston is moved by actuation of the spindle as a unit until the part 1 is arrested by an abutment 15 on the housing after which, further movement of the spindle acts through the spring to move the upper part 11 relative to the lower part, thus causing compression of the ring 2 to seal relatively to the housing. The abutment 15 may co-operate with a surface 14 on the part 1 to form an additional valve and a further pilot valve may be provided by a closure member 19 on the spindle co-operating with a seat 18 on the piston. The spring 10 abuts a nut 6 mounted on the spindle and the spring loading may be adjusted by withdrawal of the spindle until the nut abuts a projection 25 and is held against rotation. Rotation of the spindle then adjusts the spring loading. In operation, the spindle is held against rotation.

Title: Improvements in or relating to voltage stabilizer devices
Inventor: GASKILL CHARLES DAVID SINCLAIR
IPC: G05F1/595
Filed: 1960-02-10
Abstract: 979, 782. Automatic voltage control. INDUSTRIAL PROCESSES Ltd. May 4,1961 [Feb. 10, 1960], No. 4670/60. Heading G3R. In a system for stabilizing the voltage applied to a load, a pair of transistors are connected with their collector-emitter paths in series with each other and the load, the base potential of one transistor being controlled in dependence on the difference between the load voltage and a reference voltage, a voltage source and a resistance being included between the emitter of the one transistor and the base of the other to limit the collectoremitter voltage of the one transistor and the base current of the other transistor respectively. In Fig. 5 the D.C. output of a full wave germanium or silicon rectifier GR1, GR2 is applied through series connected transistors PT7, PT6 to the positive and negative output terminals shown. A control voltage dependent on the output voltage is derived from a potentiometer R11, R12, R13 to which is also applied a voltage, stabilized by Zener diodes Z2, Z3 from a further rectifier GR3 to increase sensitivity. The control voltage is compared with a reference voltage, derived from a Zener diode Z1, in a circuit including a long tailed pair of transistors PT1, PT2. Any difference is applied through a transistor amplifier PT3, PT4 and an emitter-follower transistor PT5 to vary the impedance of transistor PT6 so that the output voltage is stabilized. The use of the two transistors PT7, PT6 reduces the maximum collectoremitter voltage and the voltage from rectifier GR3 included in the circuit interconnecting the base of transistor PT7 with the emitter of transistor PT6 is such that, for large control voltages, the voltage across transistor PT6 is maintained constant at a value just less than the maximum permissible. Use of a neon stabilizer in place of Zener diode Z, and application of positive feedback to transistors PT1-PT4 is referred to. Other embodiments involving three transistors in series, further transistor amplification, use of bridge-type rectifiers, and/or surge limiting circuits involving diodes or capacitors, are described.

Title: Process for dyeing wound packages
Inventor: CAPPONI MIRO
IPC: D06P3/66
Filed: 1962-02-08
Abstract: Fibres or filaments of natural or regenerated cellulose are dyed with reactive dye by a process which comprises mounting rounf packages of the cellulosic fibres or filaments on a hollow perforated tube which forms the axis of a centrifuge, pumping the alkaline solution of a reactive dye through the hollow axis into the package and then hydro-extracting the package and fixing the dyeing.  The dye solution may also contain a melting agent which is preferably low-foaming, e.g. a mixture of an organic solvent and an anionic compound such as an aliphatic sulphonic acid, as well as a neutral salt such as sodium chloride or sodium sulphate, to assist the fixation yield.  The specified alkalis are sodium hydroxide, sodium carbonate, trisodium phosphate and their potassium analogues.  An anti-foam agent, e.g. of the silicone type, may also be included.  The apparatus consists of a centrifuge hand which supports the package, the centrifuge housing, the driving mechanism and a feed tank equipped with a circulatory pump.  At the centre is fitted a perforated conical tube upon which the package is mounted.  From the bottom of the centrifuge mounting, which remains stationary, the excess liquor is drained off and recirculated.  The rotating speed of the centrifuge is 1000-6000 r.p.m. i.e. 1000-2500 r.p.m. for impregnation and 2500-5000 r.p.m. for hydroextraction.  For operation, either the dye liquor may be pumped upward through the hollow axis, with or without pressure, by means of a rotating packing ring fitted between the motor and the centrifuge head in which case the total impregnating and hydro-extracting time is preferably 40-90 seconds, or impregnation is carried out while the package is stationary by pumping the liquor through a flexible tube into the perforated conical tube from the top downward and under pressure, e.g. 1 atmosphere, until the liquor runs out evenly on the outside of the package then the tube is detached and the package is hydro-extracted for 20-60 seconds.  In the latter case the rotating packing ring between the motor and the centrifuge head may be omitted.  Fixation may be achieved by leaving the packages in the moist state for 3-48 hours or by steaming at 100-105 DEG C.  Examples of dyeing cotton, linen and viscose staple are given in which many reactive dyestuffs are specified.  Specifications 751,244 and 904,581 are referred to.

Title: Improvements in or relating to sewing machines
IPC: D05B19/00
Filed: 1918-03-20
Abstract: 143,276. Vickers, Ltd., and Francis, C. E. March 20, 1918. Sewing-machines; needles, vibrating.-Relates to sewing-machines having mechanism for laterally vibrating the needle, of the kind comprising a lever or similar device connected to the needlebar and oscillated by a cam or the like. The invention consists in mounting the lever b on a member such as the slide c capable of being moved relatively to the body of the machine to vary the position of the " neutral " line of the stitches, i.e. the line of stitching made by the needle when the mechanism is set so as to produce no lateral vibration thereof, and in providing means, such as an axially movable cam a, for determining whether the needle vibrations take place across the neutral line, or terminate thereon on either side, operated by a camber such as a slide e capable of movement independently of the levercarrying member. The slide e is mounted on the slide c working in fixed guides on the frame of the machine, and has a fork e<1> engaging a groove in the cam. The cam-follower b<4> has a rectilinear movement in fixed guides and is connected to the lever by a pin-and-slot device. Spring plungers e<2>, e<3>, c<2> are provided on the slides, by which they may be locked in any adjusted position relatively to the machine frame or connected together for simultaneous adjustment A hand-lever g<3> pivoted on the frame carries similar spring plungers g<1>, g<2> by which :.t may be connected to either or both of the slides. Automatic adjustment according to a pattern may be obtained by a suitable cam i driving a lever i<1> connected by a link i<2> with an arm g<5> of the lever g<3>. The amplitude of lateral vibration of the needle is varied by moving the connexion between the lever b and the connecting-rod b<2> to or from the lever fulcrum b<1> through the medium of a link f<1>, lever f, link f<3>, and treadle-rod f<5>, which is moved upwards against the action of a spring f<6> and carries stopcollars f8, f<9>. The adjusting-lever g<3> may be connected to this mechanism by an arm g<4> linked to a lever h which is connected by a link h<2> to a block h<3> adjustably clamped in an arcuate slot in a member h<4>, which is mounted in vertical guides on the lever f and may be clamped thereto by a pin h<5> and nut.

Title: A method for simultaneously and interferometrically detecting a plurality of dimensions
Inventor: MOTTIER FRANCOIS
IPC: G01B9/02
Filed: 1969-01-29
Abstract: 1,212,641. Optical ranging. BROWN, BOVERI & CO. Ltd. 29 Jan., 1969 [31 Jan., 1968], No. 4969/69. Heading H4D. In an interferometer ranging device capable of simultaneously measuring two path lengths, X and Y, a laser beam 22 is circularly polarized by “ wave plate 5 and is then divided by prism system 6 into a measuring beam 24 and a reference beam 23. The measuring beam travels over the first of the paths X to be measured, to a further beam dividing prism system 14. Partial beam 25 is linearly polarized in the Z plane by filter 25 and is then redirected by adjacent corner reflector 18 along said first path. Partial beam 26 is linearly polarized in the X plane by filter 19 and then travels over the second path Y to be measured to a remote corner reflector 20 and back again to prism system 14. The two partial beams, retaining therein their distinctive polarizations are combined by the system 14 and retrace the first path to prism system 6. The two partial beams interfere with the reference beam in the prism system 6 and the two interference patterns are separated out by analysers 11 and 12. The interference causes an intensity modulation of the beams incident on the detectors 9 and 10 as the path lengths vary. The corresponding pulses in the outputs of the detectors 9 and 10, when counted allow the determination of the dimensions X and X + Y in multiples of the laser wavelength. To determine the sense of any change in X or Y, a path length variation across the diagonal interface of system 6 is produced by means of wedge thereat a few wavelengths in thickness, thereby producing a striped interferance pattern across the detectors. The detectors comprise pairs of photo detectors separated by a quarter of the distance between maxima in said pattern, whereby phase detection means coupled to the pairs of photo detectors enables said sense to be determined.

Title: Improvements in means designed to facilitate the take-off and landing of aircraft
IPC: B64C23/00
Filed: 1939-02-18
Abstract: 524,913. Aircraft with rotary wing systems. HAMMOND, E. V. Feb. 18, 1939, No. 5460. Addition to 499,632. [Class 4] An aeroplane is fitted with a rotor or rotors similar to those described in the parent Specification, but without retracting means, the stabilizing devices of the aeroplane being adjusted as the rotor system is speeded up or slowed down. A single bladed rotor 3, Fig. 1, is mounted on a shaft 5 with a counterbalance weight 4 and normally trails in the wind. Articulations 7, 8 are provided at the blade root. When additional lift is required the rotor is speeded up as described in the parent Specification and the tail plane is simultaneously adjusted. For this purpose the shaft 5 drives a shaft 11, Fig. 3, through bevel gear 10, the shaft carrying a weighted lever 13 which tends to move in the position shown in full lines, against the action of a spring 17 as the shaft speeds up. A worm wheel splined to a second shaft 11a is drawn, by movement of the lever 13, successfully through the positions 22, 22a, 22b and when in the position 22b it engages a worm 26 driven from the shaft 5, so that the shaft 11a is rotated. This shaft drives through friction gear 31, 31a, Fig. 5, a screwed shaft 33 which traverses a nut to raise the tail plane 34. Tumbler gear reverses the direction of rotation of the worm 26 when the rotor is slowed down. A machine with two rotors mounted over the wings also is described, the two rotors being adapted to be driven in opposite directions through bevel gear and transverse shafts geared to a central longitudinal shaft. The following features described in the parent Specification may be used. The rotor shaft drive and brake and a variable surface tail plane or extensible and retractable tail planes may be used. An extensible and retractable rotor or rotors at the tail may be employed for stabilizing. The pitch of the rotor blades may be controlled and maintained at the no lift angle as the rotor is speeded up and then changed to a positive angle as the driving means are disconnected.
