Abstract: 766,054. Electrostatic generators. SOC. ANON DE MACHINES ELECTROSTATIQUES. March 8, 1955 [March 10, 1954], No. 6791/55. Class 35. An electrostatic generator of ignition impulses comprises a main generator GP of insulating charge-carrier type excited by a further machine GE of the same type which is primed by a third machine P of rapid build-up characteristic which is centrifugally de-coupled after starting. The starter machine P, which is of the construction described in Specification 766,055, may be connected to one of the working ionizers 13 of the exciter or to an independent plate 42 and ionizer 41. The exciter has two sets of plates and ionizers acting in opposite sequence to produce self-excitation, while the main machine has three sets acting in parallel. As shown in Fig. 3, all three machines are on the same driving shaft 1 and enclosed in the same pressure housing 3. The priming machine has an insulating rotor 48 having charge carriers 49 embedded in it. The stator comprises an annular insulating channel 6 faced with chargeinducing plates 47. A centrifugal weight 52 acting on a cam-surface 53 serves to lift the rotor and disconnect its contact 50, 51 as the speed rises. The self-excited exciter comprises an insulating charge-carrying rotor 55 between inducing plates 56 and ionizers 57. The main generator consists of an insulating chargecarrying rotor 60 between ionizers 22 and inducers 61. The capacitance C between these inducers and the casing serves as a reservoir from which an ignition discharge may be drawn by the contact 39 of distributer D. Suitable dielectric media are hydrogen at 10-20 Kg. per sq. cm, and nitrogen at at least 5 Kg. per sq. cm. The exciter may be primed by a frictional machine, by an induction coil, or by radio-active ionization, and the priming machine may be spring accelerated. The machine may be driven by an electric motor. Specifications 719,687, 753,199, 766,053, 766,055 and 766,056 also are referred to.

Abstract: 869,899. Electrical measuring devices. LANGHAM, E. M. March 3, 1959 [March 3, 1958], No. 6814/58. Class 40 (1). A device for measuring relative movement between two members, e.g. the movement of a workpiece or tool relative to the bed of a machine tool, comprises a rod of magnetic material wound with at least one winding the pitch of the turns of which is at any point along the winding proportional to the distance between that point and a datum point on the rod, a portion of the rod being surrounded by a movable sleeve of a magnetic material having at least one winding which provides a uniform flux along the length of the sleeve such that the voltage induced in the rod winding by A.C. in the sleeve winding is proportional to the displacement of a datum position on the sleeve relative to the datum position on the rod. Construction, Fig. 1.-As shown, a rod 1 slides through sleeve 4 bellows 2 being provided to prevent the ingress of dirt &c. between the sliding surfaces. The rod is preferably manufactured from strips of high permeability material, e.g. " Mumetal " (Registered Trade Mark), and the variable pitch winding may be applied by placing a wire in a groove cut in the magnetic material or alternatively by cutting or photo-etching a variable pitch helix in a tube of copper shrunk on the rod, the winding being symmetrical about the centre of the rod which is the datum point referred to above. The rod is preferably provided with two such windings insulated from each other and the rod. The sleeve has three windings two uniform pitch centre-tapped windings and one winding similar to the rod windings. Circuit arrangements, Fig. 6.-The two centre-tapped uniform windings 18, 20 and the variable pitch sleeve winding 17 are connected to feed-back amplifiers 33 and 34 and a reference voltage source at terminals 30 in order to produce a uniform field in the sleeve. The non-uniform pitch rod windings are shown at 12 and 9, 9 being the inner winding on the rod which is fed, from cathode followers 41 and 42, with a signal similar to that induced in winding 12 in order to minimize the effects due to capacitance between the rod windings and the rod. An auto-transformer 38, whose centre tap is earthed is included in order that the output taken from its ends, which varies in accordance with the relative positions of rod and sleeve, may be balanced about earth.

Title: Improvements in or relating to lubricating grease compositions
Filed: 1950-03-21
Abstract: A lubricating grease composition comprises a major proportion of lubricating oil and a minor proportion of a metal soap of a keto acid of the C12-C22 aliphatic monocarboxylic acid series.  The keto acid may be derived, for example, from palmitic, myristic or lauric acids; 4-keto stearic acid, derived from hydrogenated oiticica oil and 12-keto stearic acid are particularly mentioned.  Soaps of alkali or alkaline earth metals, especially of calcium, may be used.  The lubricating oil may be mineral oil and/or synthetic oil such as the dibasic acid alkyl esters or polyglycols.  From 5-30 per cent. of the soap may be used in forming the grease.  The grease may be prepared by mixing the fatty acid or ester with mineral lubricating oil, adding the metal base saponifying agent, heating and then adding more lubricating oil.  The greases may contain other soaps such as those of hydroxy acids or normal fatty acids, and also other conventional additives.  Specification 669,206 is referred to.

Abstract: 671,261. Calliper gauges. KRATZER, H. March 21, 1950, No. 6980/50. Class 106 (ii). A sliding calliper gauge for marking off a work-piece W is provided with overlapping offset jaws 2, 8, so that a scriber point N may be used with greater accuracy than in the case of a gauge with jaws in the same plane. The back face 11 of jaw 2 may be used in conjunction with the face 11<SP>1</SP> of jaw 8 to measure a workpiece G as shown in Fig. 3. When closed, the jaw 2 overlaps jaw 8 so that the faces 10, 101 are in the same plane. Fig. 4 shows the calliper gauge in use, the measuring limb 2 lying flat on the face of the work-piece W whilst the gauging face 10 of the other limb is in contact with the side R of the work-piece, thus avoiding small errors due to the slight inclination necessary when both gauging faces are in the same plane.

[Classes 83 (ii) and 83 (iv)] [Also in Group XXVIII] Soldering; coiling.-Tubes of molybdenum, tungsten, or alloys containing a major portion of at least one of such metals, are made by winding a close coil of such wire, obtained by powder metallurgy, on a machinable metal mandrel, securing the ends to the mandrel by spot-welding &c., applying brazing material along the length of the mandrel, placing upright with one end in a cup of similar material, enclosing in an envelope and evacuating some heating electrically by high-frequency current so as to melt the brazing material and fill any spaces by capillarity, then allowing to cool and removing the mandrel. A wire 12 of trapezoidal section is coiled on a mandrel with its short side 15 on the inside so that due to stretching of the outer portion during coiling the sides 16, 17 in the finished coil are parallel to each other. The mandrel may be of iron or steel and may be removed by drilling or by treatment with acid.

Abstract: 397,571. Impedance networks. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and LEY, D. A., c/o General Electric Co., Coventry. March 14, 1932, No. 7527. [Class 40 (iii).] A low-loss transformer terminating-impedance for a filter is matched over a substantial part of the pass range but mismatched in the attenuation range. Thus the network shown is matched in the pass range to a filter connected at 1, 2, while a valve input circuit of infinite impedance is connected at 3, 4. The Specification gives examples in which for a T-section filter the match is effected for the geometrical mean of the cut-off frequencies of the filter ; the termination shown is made resonant at this frequency and its (purely resistive) impedance at that frequency is made equal to the image impedance of the filter. A further relation is obtained by equating the real part of the terminating impedance to that of the filter image impedance at a frequency midway between one of the cut-offs and the geometric mean of the cut-offs. The Specification also gives an example of a lattice-section filter in which matching is effected at the mid-frequency of the pass range and at frequencies near the cut-offs.
