Title: Improvements in or relating to the transmission of high frequency oscillations over high power conductors for high frequency telegraphy and telephony
IPC: H04B3/56
Filed: 1920-10-22
Abstract: 154,884. Ges. fiir Drahtlose Telegraphie. Dec. 1, 1919, [Convention date]. Electric oscillations in line-wires, telegraphing, telephoning, and signalling by.-In high-frequency telegraphy and telephony over high-power conductors, the stations are capacitatively coupled to the conductors at distances from the ends equal to a quarter of the wave-length or to an odd multiple of this amount, the electrical portion of the electro-magnetic field being thus utilized for the coupling. When using more than one frequency, distances are used corresponding to the best intermediate value. In order to prevent the formation of a number of stationary waves out of phase with one another, artificial elements are added to compel the formation of only a single stationary wave, such elements being short circuits (condensers) or interrupters (inductances).

Abstract: 1,086,863. Retractive switches. JOSEPH LUCAS (INDUSTRIES) Ltd. Aug. 4, 1964 [Aug. 2, 1963], No. 30690/63. Heading H2B. A vehicle with a compression-ignition engine has an ignition switch with an actuating shaft 25 spring-biased to a rest position but movable axially to actuate the contacts (61), (62) (Figs. 5-7, not shown) of a starting aid and rotatable in a first direction to actuate the contacts (61), (63) of the starter motor or rotatable in the opposite direction to operate a fuel supply valve, via a lever 37 having a plate part 36 loose on shaft 25 such that it is moved only when the shaft is rotated in said opposite direction (Fig. 2, not shown). The switch shaft is retractive both axially and angularly unless moved in the lever-actuating direction, when it is latched by a catch lever 46 engaging a pin 49 (see also Fig. 4, not shown). Actuation of a lever 47 releases the catch lever 46 and a torsion spring 31 returns shaft 25 to its initial rest position. A lock 45 may prevent such actuation of release lever 47 by moving a cam 51 into its path. Contact plates 53, 54, on shaft 25 carry the movable contacts 56, 55, for co-operating with a contact block 24, which carries fixed arcuate contact pieces (61), (62), (63), connected respectively to the battery, starting aid and starter. A handle 43 is detachably locked to shaft 25 by a spring-loaded pin 44. A heating coil 66 visible through a window 67 indicates the condition of the starting aid heater coil, which is energized by axial movement of the shaft, so that when coil 66 glows shaft 25 may be turned to energize the starter motor. Alternatively, with the shaft (73) (Figs. 8-12, not shown) depressed and then rotated to the position for energizing the starter motor, a latching bimetal (91) prevents closure of the appropriate contacts (85), (87) by movable contact (79) on plate (78) until after an adjustable time delay during which the bimetal (91) is heated by a heating coil (92) in parallel with the starting aid heater coil. After the predetermined time, the heated bimetal moves to unlatch a sleeve (81) and allow rotation of plate (78) by a stressed spring (84) so that contact (79) completes the circuit to the vehicle starter, angular movement of the shaft (73) being imparted through a contact plate (76) thereon and torsion spring (84) to the sleeve (81) and thence plate (78).
