Abstract: 1,041,668. Automatic voltage control. STANDARD TELEPHONES & CABLES LTD. Sept. 11, 1963, No. 35848/63. Heading G3R. [Also in Division H2] A protective arrangement for a power supply circuit comprises a semi-conductor controlled rectifier SCR connected in series with a resistor R5 across the protected circuit, a firing potential being applied to the gate of the SCR to render it conductive in the event of overvoltage or overload so that the resulting increased current flowing through a fuse F blows the fuse. In the circuit of Fig. 1 a transistor series regulator SR is controlled by a comparator C having an input from a voltage divider SN and an input from a voltage reference, e.g. a zener diode or gas-discharge tube. The gate of the rectifier SCR is connected to the junction of resistors R3, R4 which are connected in series with a transistor VT1 having its base connected to a potential divider R1, R2 connected across the output terminals. In the event of overvoltage, the transistor is rendered conducting so that the resulting potential across resistor R4 causes the rectifier SCR to fire and conduct so blowing the fuse F. Figs. 2 to 4 (not shown) illustrate modifications in which the transistor is not used and/or a zener diode and a separate supply are connected to the lower end of resistor R2. In the overload responsive arrangements of Figs. 5 and 6 (not shown) the firing potential for the SCR is derived from a potential divider connected in series with a zener diode across a resistor which is connected in series with one of the supply lines. Reference has been directed by the Comptroller to Specification 1, 005, 261.

Abstract: 339,771. Hands, F. C. Nov. 27, 1929. Actions, pneumatic; re-winding-mechanism.- A valve which connects the ducts of a pneumatically operated automatic musical instrument to suction for playing, is reversed to connect the ducts to pressure air for cleaning, the pressure air passing in the reverse direction. In Fig. 1, the usual bleed hole 1 of a tracker-duct 14 nas its connection to suction at 6 through the reversing-valve 7 which is operated by a diaphragm 8 to connect the bleed to pressure at 5 for cleaning. The bleed hole may be formed in a celluloid disc 1<a>. In Fig. 3 the action is connected at 15 and thus is connected to pressure at 5, in lieu of suction at 6, on operation of the valve 7 by hand-control of the duct 17 of diaphragm 16. The reversing-box also contains a valve 22 which operates the re-wind mechanism and is operated from a tracker-duct connected at 21: on operation also of the valve 7, pressure air reaches chamber 23<a> by duct 24, reversing diaphragm 23 and expelling dust from duct 21. During this action also a diaphragm 28 is inflated by the pressure air to assist the return movement of the diaphragm 23. The re-wind mechanism is put into operation as follows :- With suction in the chamber 23<a> from the chambers 15, 6, tracker operation at 21 of the diaphragm 23 connects chamber 22<a> to suction. To accelerate the re-wind action, chamber 22<a> is connected to a bellows operating a valve controlling a duct 18. A valve 19 is thus reversed, operating more powerful re-winding mechanism. To facilitate cleaning or inspection of the passages 17, 18, 21 each may be formed with a transverse passage provided with a cover-plate.

Abstract: 367,931. Bomb-dropping. AIRCRAFT PATENTS, Ltd., 4, Broad Street Place, and COOKE, G. H., 28, Dalmeny Avenue, both in London. Des. 3, 1930, No. 36486. [Class 9 (ii).] Electric circuits and switches for controlling bomb-releasing devices are so arranged that the operation of certain switches determines which bomb or bombs are to be dropped, and the operation of other switches serves to drop the selected bombs or all the bombs. Electric lamps are also provided to indicate that the circuits are operative ; and electromagnetic devices and switches therefor are provided to cause the fuzes of the released bombs to be armed or not. As shown in Fig. 1, electric devices a<1>, a2, a3 adapted to release bombdropping gears (not shown) are connected on one side through a main switch c to one pole of a battery b, and on the other side to selector switches d<1>, d<2>, d<3> moving between contacts e<1>, e<2>, e<3> and f<1>, f<2>, f<3> connected to bus-bars h, j, respectively. A switch k is interposed between the bus-bar and a bus-bar connected to the battery b ; and switches m<1>, m<2> mechanically coupled together are interposed between the bus-bars h, j and the battery b. The bombs to be dropped are selected by moving their corresponding selector switches d<1> .. to their contacts f<1> .., and the selected bombs are dropped by the operation of the switch k, which closes the circuits of the selected devices a<1> .. only. If it is desired to drop all the bombs, the switches m<1>, m<2> are operated and close all the circuits. A lamp p<1> between the bus-bars j, l indicates that the circuits are operative. Another lamp p<2> between the busbar and a bus-bar q connected to contacts g<1> .. at the selector switches d<1>.. indicates each time a particular selector switch is operated that the corresponding circuit is operative. In a modification, the switch k is replaced by a two-way switch adapted to connect the busbar j to the bus-bars h or l, and the double switch m<1>, m<2> is replaced by a single switch adapted to make or break the connection between the bus-bar h and the battery b. To control the arming of the fuzes, electromagnetic devices r<1> , Fig. 3, for performing the arming or disarming of the fuzes are connected through selector switches t<1>, t<2> to a bus-bar u connected to a contact k<2> of the switch k, so that the control circuit of the fuzes is closed before the bomb-dropping circuit is closed at the contact k<1>. To ensure a sufficient time delay between these two operations, additional resistance, for example a second spring, may be introduced to check the switch after the contact k<2> is reached ; the single switch may be replaced by two switches coupled together. The Provisional Specification also describes details of the electromagnetic fuze-setting devices and means for selecting which fuze of a bomb provided with more than one fuze shall be put into operation.

In a termination of a high frequency, coaxial power cable, power is transferred to or from the cable in a radial direction by a coaxial coupling structure 3, 4 and coolant 6 is passed into or out of the hollow inner cable conductor in an axial direction by a duct; screening being provided to shield the coolant 6 in the duct from the electric field of the cable and to shield the terminated cable end from its surroundings. In the embodiment of Fig. 1 an insulating coolant duct 5a is screened by a metal cone 9 connected to the inner cable conductor 1 and is surrounded by a metal screen 7 connected to the outer conductor 8, the inner conductor 1 being supported by an insulating plate 2. A resilient metal pipe (not shown), e.g. of corrugated brass, may connect the conductor 1 and the duct 5a to allow for expansion. In other embodiments (Figs. 2, 3, not shown), the core 9 is omitted and the coolant 6 passes through a coiled metal duct (5b, Fig. 2), preferably having a ferrite core, or a linear metal duct (5c, Fig. 3) which threads metal discs. In each case the duct (5b or 5c) is short-circuited with the screen 7 at its exit therefrom to provide a coaxial delay line which is dimensioned to match the impedance of the cable to provide the termination with a low reflection factor. This factor may be further reduced by balancing the reflection factor of the delay line, which acts as a parallel-resonance circuit, with a series-resonance circuit in place of the inner conductor 3 of the coupling structure.
