Title: Improvements relating to the feeding of thermionic valves from a source of current containing disturbing components
IPC: H02M1/14
Filed: 1927-08-03
Abstract: 275,624. Siemens & Halske Akt.-Ges. Aug. 4, 1926, [Convention date]. Drawings to Specification. Thermionic valve circuits.-Relates to filtering arrangements for eliminating hum from the voltage supplied to thermionic valves, and consists in dividing the filter into independent sections each designed according to the amperage of the valve or group of valves with which it is associated, anode voltage being supplied separately to each valve or group. Thus for the first valve, which acts as a voltage amplifier and has small output current, the filter in the anode circuit consists of a high resistance shunted by a capacity. For subsequent valves, lower resistances and, if desired, larger capacities are employed, while for the power valves, which have a small amplification factor but large, output current, the filters may be of the kind comprising choking coils.

Title: New complexes, process for preparing them, and their applications
IPC: C08F10/00
Filed: 1965-05-14
Abstract: The invention comprises complex hydrocarbon/metal halide polymers of formula <FORM:1093457/C3/1> or <FORM:1093457/C3/2> where M is a metal of Groups V, VI, VII or VIII of the Periodic Table which is capable of forming a metal carbonyl, p is the valency of the metal M, X is a halogen atom, n is an integer (e.g. 1,500 to 5,000), and R and R1 are hydrogen atoms or alkyl, aryl, aralkyl or alkaryl groups which may be halogenated.  The polymers are obtained by reacting halogenated olefins and halogenated aromatic hydrocarbons with metal carboxyls in solvents at 0 DEG  to 250 DEG  C. When contacted with water the polymers lose the metal halide and form polymers containing no metal halide.  In examples polymers are obtained by reacting 1,4-dichlorobutene-2, 3,4-dichlorobutene - 1, 1,4 - dichlorobutene - 1 and o ,o  - p - dichloroxylene with nickel carbonyl and iron carbonyl, and the products are contacted with water to obtain hydrocarbon polymers.

Abstract: 665,096. Cathode-ray tubes. ELECTRIC & MUSICAL INDUSTRIES, Ltd. July 6, 1948 [July 31, 1947], No. 20727/47. Drawings to Specification. Class 39 (i). In a televion receiving tube, the cathoderay beam is given an elongated form in crosssection, and the major dimension of the crosssection lying transversely of the direction of line scan is maintained constant over the whole area of the screen, by compensating for variations due to the picture signal modulation or to the deflection of the beam from its centre position. The beam passes through a non- uniform transverse magnetic or electrostatic field which imparts to the beam an elliptical cross-section, and is varied in strength so as to compensate for the variation of the major dimension of the cross-section. As regards the picture signal modulation the field strength is varied in accordance with the picture modulation amplitude; as regards the deflection of the beam from its centre position the field strength is varied in accordance with the added integrated outputs of the line and frame scan generators. The transverse non-uniform field is formed between a pair of equal and opposite coils, or between a pair of arcuate electrodes fed in push-pull, and is located between the modulating electrode and the deflection system. Specifications 622,002 and 661,266. [both in Group XL (b)], are referred to.

Abstract: 601,669. Self-contained supply systems. O'BRIEN, J. F., and CATALDO, J. B. Oct. 25, 1944, No. 20735. [Class 38 (iv)] [Also in Group XXXVII] Variable-speed generators, with. A cut-out system for a variable voltage source operating in parallel with a constant voltage source comprises : '(1) a main switch in the interconnection between the sources and actuated by " on " and " off " coils; (2) a polarized relay including a permanent magnet, a reverse current coil and a voltage coil, the last being connected across the main switch, and (3) a secondary switch controlling the " on " and " off " coils under the influence of the polarized relay. As shown the cut-out is used in a system wherein a generator is connected to charge a battery. A permanent magnet 30 co-operates with an iron clapper 31 to which is fixed an armature 34 which passes through a coil 55, connected across the poles of a main switch, and a looped portion 35 of a conductor 15 in the battery charging circuit. A main switch 50 comprising a snap spring 22 of the type described in Specification 582,185, [Group XXXVII], is operated by " on " and " off " coils 51, 52 which are selectively energized by a relay 59, an ancillary switch 54 ensuring only momentarily energization of the coils. With the main switch open and switch 5 closed, the coil 55 operates when a sufficient voltage differential has been built up between the generator and battery to give the clapper 31 a polarity causing it to be moved clockwise so operating relay 53 and closing the main switch 50. Reversal of current in the loop changes the polarity of the clapper and causes it to be drawn to the opposite pole of the magnet 30 de-energizing the relay 53 and opening the switch 50.

Title: One-way engaging device
IPC: F16D41/07
Filed: 1968-05-02
Abstract: 1,200,676. Ratchet clutches and brakes. GEORG MULLER KUGELLAGERFABRIK K.G. 2 May, 1968 [14 March, 1968], No. 20900/68. Headings F2C, F2E and F2Q. To increase the number of sprags and hence load capacity in a sprag-type one-way clutch or brake device having cylindrical or planar raceways, each sprag has at least one racewayengaging end face that is laterally undulated in the tilt axis direction, the undulations of adjacent sprags being complementarily shaped for nesting of the sprags. Applications include gas turbines, reversing transmissions and machine tool feeds. Undulation waves at the inner and outer end faces of the sprags may be of identical amplitude, length and phase (Figs. 2-4, not shown), of identical amplitude and length but phase-displaced one half wavelength (Fig. 5, not shown), of unequal length, or, as shown, of unequal amplitude, equal length and phasedisplaced one half wavelength, such latter form being produced by swinging the cross-section of the sprag about an axis 30 in alternate directions as the section proceeds axially of the device, the axis 30 being disposed parallel to the device axis. The sprag, as shown, having therefore greater and smaller wave amplitudes of their end faces 31, 32, has respectively interrupted and continuous engagement with the corresponding device races, such that where the greater and smaller amplitude wave faces engage the outer and inner races the same engagement pressure may prevail. However, the sprags may be fitted in the opposite manner, in which case the torque capacity is reduced. As shown, the sprags have hooks 39, 40 for engagement by garter springs 41, the latter being tension or compression springs depending on whether the large or small amplitude and faces engage the outer race. The spring seats on the hooks are formed of two arcs of different radius for rapid movement of the sprags to their near engagement position. Projections 42, 43 and 44, 45 are provided for retention of the sprags in two relatively rotatable cages. In Figs. 15-17 (not shown), a centrifugal weight and spring arrangement is provided to act on the two cages to compensate for the effect of centrifugal force on the sprags which effect tends to cause the sprags to engage the outer race in the disengaged condition. A lever on which the centrifugal weight is mounted may also be used for optional, mechanical, device disengagement. In Fig. 18 (not shown), the two cages are provided with turbine vanes so that, to avoid wear, the sprags may be controlled by drag of oil associated with the device. The sprags end faces may be of logarithmic curve shape.
