Title: An improved seal for use between relatively rotatable elements
IPC: F16J15/32
Filed: 1962-09-10
Abstract: 1,072,941. Seals. G. BLAIR. Dec. 9, 1963 [Sept. 10, 1962], No. 34528/62. Heading F2B. In a seal for preventing leakage of lubricant between a stationary element and a rotatable element, e.g. an axle and a railway axle box, and comprising a sealing ring 23, Figs. 1 and 2, located between carrier plates 24, 25 and supported circumferentially by a spacer 27 between the plates, the sealing ring is provided in its lower part with a pair of spaced recesses 35, Fig. 3, extending through the radial width of the ring adjacent the plate 24 and with a portion 33 which projects between the recesses 35 at least to the contiguous surface plane of the plate 24 and is adapted to be laterally distorted into either of the recesses upon rotation of the rotatable element to serve as a scraper or deflector for lubricant tending to enter between the seal ring and the rotatable element. The projecting portion 33 may be in the form of a block of the same resilient sealing material as, and of greater thickness than, the ring so that when it is compressed upon securing the plates 24, 25 on to the spacer 27 it projects as a flexible tongue 36 into or through a radial recess 34 in the plate 24, the upper surface of the tongue projecting into the circle defined by the inner periphery of the sealing ring. The lubricant scraped from the axle by the tongue 36 is deflected away from the sealing ring into one of the recesses 35, depending on the direction of rotation of the axle, and flows through one of two channels 27 in the spacer 27. The sealing ring 23 may be of plastic or rubber, e.g. neoprene, and may be non-porous or wholly of sponge-like or cellular structure or has an inner peripheral cellular, slitted or pitted surface layer for retaining lubricant so as to reduce friction between the ring and the axle. Alternatively, the sealing ring may be of a reinforced, lubricant-impregnated textile or textile bonded material. The plate 24 and the spacer 27 may be of plywood and the plate 25 of hardboard. The seal may be mounted, in the manner described in Specification 983,139, to float transversely to the axle, being pressed by springs so that the plate 25 is in frictional engagement with an inclined or normal surface of the axle box. In Fig. 4, the projecting portion 38 is moulded integral with the ring 23, which may be split at the top, and extends to the inner side of plate 24. The latter is formed with two radial recesses having oblique surfaces 39 extending outwards and downwards from the adjacent edge of the spacer 27 and, between the recesses, with a nose 40 extending up the lower part of the portion 38 so that its upper part is free to deflect to serape off lubricant which drains away by one of the channels 35 and over the corresponding surface 39 in plate 24. The drain recesses with the oblique surfaces 39 may be substituted for the channels 37 in a modification of Figs. 1 to 3 and the channels 37 may be substituted for the drain recesses in a modification of Fig. 4.

Title: Improvements in duplex telegraphy and telephony
IPC: H01Q5/00
Filed: 1920-12-15
Abstract: 157,889. Soc. Franþaise Radio-Electrique. Jan. 16, 1920, [Convention date]. Duplex signalling; wireless systems.-In duplex wireless or line telegraphy, the receiver is connected to two points 1, 2 of the antenna or line, the potential difference between these points due to transmission being annulled, so that the receiver is not affected by transmission. Transmission is effected through a transformer 3, and the potential difference between the points 1, 2 is annulled by a transformer 4<1> connected to a source having the same frequency as, but differing in phase from, that supplying transformer 3. If desired, a second transformer 4" may be used, stated to annul the effect of the transformer 4<1> on the transmission. The effect of the transmission may be compensated for by acting upon a part of the circuit of the currents to be detected instead of upon part of the antenna circuit, or the two methods may be combined. Fig. 4 shows the transformers 3, 4 in the anode circuits of valves 6, 7 respectively. The anode circuit of a valve 8 includes a transformer 14 so as to react on the circuit of the currents detected by the receiver 12. Phase adjustment of transformer 4 is effected by a condenser 9 shunted by inductance 10. An arrangement is also described in which valve 8 and transformer 14 are omitted, and the receiver 12 is directly connected to points in the antenna circuit on opposite sides of transformer 4.

Abstract: 1478958 Control of D.C. motors SIMMS GROUP RESEARCH & DEVELOPMENT Ltd 18 July 1974 [25 July 1973] 35432/73 Heading H2J A motor control system comprises a D.C. motor having a reversible armature 10 and a plurality of field windings 11 each in series with a respective transistor 12, the series combinations being connected in parallel to form an arrangement in series with the armature 10, Fig. 1 (not shown), all the transistors 12 being simultaneously controlled by a variable mark/ space ratio oscillator 26 and each combination 11, 12 being associated with a circuit such as that shown in Fig. 2, whereby in the event of the current through a particular transistor exceeding a predetermined value, the circuit produces a control signal which is applied to the oscillator to modify its operation to reduce the current through all of the transistors. A controller 28, for example the accelerator of a vehicle driven by the motor, determines the mark-space ratio of oscillator 26 which turns transistors 19, 12 on and off to produce a desired motor speed. The method of connection of the windings 11 and transistors 12 ensures that the winding currents are substantially equal. Each current is sensed by a resistor 15 connected to the input terminals of an operational amplifier 31 which, when the current exceeds a predetermined value, supplies a control signal via diode 36 to the oscillator 26. This signal may either terminate the oscillator cycle and so turn off the transistors 12 until the next cycle, or vary the mark-space ratio of the oscillator to reduce the currents through the windings. Members 12, 19, 31 and their associated circuitry may be mounted on a replaceable panel provided with a warning circuit composed of transformer 17, monostable element 38, 39 and a light emitting diode 37, which flashes when transistor 12 is made conductive and thus indicates correct operation.
