Abstract: 662,891. Rotary filters. KOMLINESANDERSON ENGINEERING CORPORATION. May 23, 1949 [June 11, 1948], No. 13756/49. Class 46 A filter web for a rotary drum filter comprises a plurality of parallel, contiguous, flexible filaments each constructed of a series of non-pervious elements spring- biassed closely together along the longitudinal filament axis, the spacings between the elements being controlled by tension applied along the said filament axis. As shown at 15a, Fig. 4, the elements consist of coils or turns of a helical spring, or as shown in Fig. 5, of discs or washers 36, threaded on a spring 35 so as to be biassed together along the filament axis . The elements may also consist of rings spring- biassed together. The discs or washers 36 are given slight deformations 37 to provide a minimum spacing for filtration. The filaments 15a consist of a plurality of helical metal springs made continuous by short connecting studs 27, Fig. 3, which threadedly engage the interior of the spring and at the same time form baffles to prevent the passage of liquid longitudinally through the filaments. The filaments are made endless by set studs 27 and so also the spring support 35, Fig.. 5. Half round wire is preferably used to form the helical spring shown in Fig. 4. The filaments 15, Fig. 2, on the drum 10 lie in the same horizontal plane, each filament being contiguous with the adjacent filament, the end filaments resting on inclined sealing rings 25 rigidly attached to the drum heads 26 to compensate for errors in filament diameters. The filaments 15a, Fig. 3, are placed over the .drum 10 and some at least are passed off the drum and over a discharge roller 16.

Title: Improvements in or relating to data transmission systems
IPC: H04N1/413
Filed: 1970-03-23
Abstract: 1281432 Digital transmission systems; signailing by DC SIEMENS AG 23 March 1970 [24 March 1969] 13858/70 Heading H4P The bandwidth of a facsimile-type signal produced by a computer having the form of a binary coded pulse train, e.g. corresponding to characters or symbols, is reduced so that it may be transmitted over a telephone line by dividing the elemental signals into groups of for example three elemental signals and converting each such group into a single signal whose amplitude represents the pattern of black and white image elements in the group, i.e. the signal transmitted has one of eight possible amplitudes. In the embodiment described this " binary-to-analogue " conversion is effected by two groups of three trigger stages, one of which is sampled for transmission while the other group receives information, and vice versa, the trigger stages being controlled by a pulse generation and gating arrangement, and the different amplitudes for transmission being derived from six transistors, respectively connected to the trigger stages, having collector resistors of different values. In the receiver an oscillator whose pulse repetition frequency is proportional to the received voltage amplitude is sampled and applied to two groups of three trigger stages the outputs of which are gated in synchronism with the gating in the transmitter by a similar pulse generation arrangement.

Abstract: 1,044,337. Conveyers. METALLGESELL - SCHAFT A.G. April 9, 1963 [April 10, 1962; Aug. 3, 1962; Sept. 7, 1962], No. 14193/63. Heading B8A. [Also in Division F4] A rotary hearth sinter machine 1 is charged by a roller conveyer 2, Fig. 1, the lengths of the discharge edges of the rollers varying proportionally with their distance from the centre of rotation of the hearth 1. The conveyer may extend radially inwards from the periphery, or may extend at an angle to the radius as at 3. In a modification. Fig. 2 (not shown), a roller conveyer with its discharge edges extending in the opposite direction to the rotation of the hearth is combined with a conveyer having its discharge edges extending in the direction of rotation. Marginal protective material can be fed along the edges of the roller conveyers.  A roller conveyer 7 (Fig. 3, not shown), may feed material from the centre of the hearth. It also has a hopper 8 having slots 10 extending in the direction of travel of the hearth and of arcuate length proportional to the distance from the centre may be used. In a further modification, Fig. 4 (not shown), a roller conveyer 15 with its discharge edge 19 in the radial direction of the annular grate 1 is fed by a belt conveyer 16 and the material so fed is distributed in proportion to the radial distances by pivotally and horizontally adjustable guide plates 17. The required distribution may also be obtained by tilting the conveyer about its discharge edge 19 and also about its lateral edge 21 on a lateral pivot 20. In this case the plates 17 may be dispensed with. In further modifications, the roller conveyer 15 is fed by a reciprocating or swinging conveyer belt the discharge edge of which has its greatest speed near the inner periphery and its least speed near the outer periphery of the grate. In this case the belt speed is constant. However, the speed of reciprocation may be constant and the the belt speed may vary with the point of discharge being greatest at the outer periphery of the grate. The belt conveyer may be used without the roller conveyer or the plates 17 or the pivot 20. In a further modification, a roller conveyer having discharge edges extending in a tangential direction to the grate is followed in the direction of rotation of the grate by a hopper having a discharge slot tapering radially inwardly of the grate and having a trailing edge which acts as a scraper. Alternatively a separate vertically. displaceable scraper may be provided.

Title: Improvements in and relating to phonic motor devices for television and like systems
IPC: H04N1/36
Filed: 1938-06-04
Abstract: 519,515. Television ; valve relay circuits. I.M.K. SYNDICATE, Ltd., NAGY, P., and BYRON, D. H. June 4, 1938, No. 14461. [Classes 40 (iii) and 40 (v)] [Also in Groups XXXV and XXXVI] A phonic wheel motor for use, for example, in driving a television scanning mirror 28 comprises a pair of toothed rotors 18c, 24c, mounted on a common shaft 13 and co-operating with a pair of correspondingly toothed stators one of which 19 carries driving coils 23 connected in the output circuit of a thermionic valve system while the other 26 carries pick-up coils 27 connected in the input circuit of the thermionic valve system. The teeth of the stator 19 are constituted by a series of bars which extend longitudinally beyond the rotor tunnel and are collected into groups each of which is surrounded by a coil while the several groups are joined at opposite ends by magnetic rings 20, 21. The teeth of the stator 26 are constituted by a series of bars collected into two groups (see Fig. 3) on which the pick-up coils 27 are mounted. Magnetizing coils 29 may also be provided. Speed adjustment may be effected by angular displacement of the stator 26 with respect to the stator 19 or by phase displacement of the driving impulses applied to the coils 23 with respect to the pick-up impulses from the coils 27. When the motor is applied to television scanning, synchronization may be effected by applying synchronizing impulses through a valve V3, Fig. 4, on to the control grid of the valve V2 the anode circuit of which includes the driving coils 23. Input from the pick-up coils 27 is, after amplification in a stage V1, also applied to the control grid of the valve V2, the valves V1, V2 operating to produce impulses of rectangular wave form in the driving coils 23. To avoid hunting, provision is made to ensure that any hunting frequency is not fed back to the grid circuit in such phase relation as to amplify the hunting. To produce a more even torque the stator and rotor systems may be divided mechanically and one element displaced by half a tooth pitch so as to obtain staggered driving impulses. Self-starting may be ensured by adapting the arrangement to start as a splitphase induction motor, or by coupling it to a third stator and rotor system. A modified construction is described with reference to Figs. 5 and 6 (not shown) in which the stators are built up from ordinary circular stampings with radial teeth.
