Abstract: 563,145. Metals and alloys. UDY, M. J. Jan. 27, 1943, No. 1415. Convention date, Feb. 9, 1942. [Class 82 (i)] A reaction mixture for use in preparing alloys or an alloying metal consists of a mixture of a finely-divided oxide of chromium; manganese, vanadium, tungsten, titanium, or molybdenum and finely divided calcium oxide, which mixture has been heated sufficiently to effect chemical combination between the oxides, and is then mixed in finely divided form with finely divided non-carbonaceous reducing material, e.g. silicon or aluminium. Before being mixed with the reducing material, the product of the chemical combination may be subjected to the action of an oxygen-containing gas at a temperature sufficiently high to effect conversion of at least a portion of the metal oxide to a higher state of oxidation. The reaction mixture may also contain silica for slag-forming purposes, and a small amount of sodium carbonate for promoting oxidation. For incorporating alloy metals in molten iron or steel or other metal baths, the reaction mixture is such as will react exothermically to produce the alloy metal. Silicon, as a reducing agent, is preferably employed as an alloy of silicon and the metal of the metal oxide of the reaction mixture. Aluminium may be employed as such or as an aluminium-silicon alloy.

Title: Improvements in or relating to circuit arrangements for two-motion selector switches of so-called "square" type
IPC: H01H67/16
Filed: 1936-01-17
Abstract: 469,107. Automatic exchange systems. STANDARD TELEPHONES & CABLES, Ltd., and WRIGHT, E. P. G. Jan. 17, 1936, No. 1567. [Class 40 (iv)] The circuits of a bidirectional selector of the kind which upon release continues its rotary movement to the end of the bank, are arranged to provide for the absorption of particular digits. In one arrangement the initial impulses of the first digit are received by a series of relays and only the later impulses effect vertical stepping. In a second arrangement the selector releases if raised to a particular level by the first digit, and the initial impulses of the second digit are suppressed in order to cover the release period. As shown, the first impulse operates dialling relay C, and D pulls up at the end of the impulse. The second impulse operates E, and D falls back at the end of the impulse. The third impulse operates F, and D pulls up again at the end of the impulse and remains held, subsequent impulses going to the vertical magnet VM, If the first digit is 0, relay energizes and closes a hunting circuit (not shown) for the rotary magnet RM, otherwise the selector responds. to a second digit before hunting. If the first digit is 2 or 3, relay G energizes when C falls back, and the second digit goes to the vertical magnet VM and the third digit to the rotary magnet RM. In the second arrangement, relay J and contact c4 are added ; relay G is unnecessary, and contact g2 is replaced by a make contact of J. The first digit thus goes to the vertical magnet VM. If the digit is 8, J operates and closes a homing circuit (not shown) for the rotary magnet RM. The circuits are then in condition for absorbing the first three impulses of the second digit as described above.

Title: Method of and apparatus for determining the quantity or level of liquid in a container
IPC: G01F23/00
Filed: 1925-01-20
Abstract: 252,218. Rosenmund, A. L. Jan. 20, 1925. Indicating by measuring height of trapped column of liquid.-The quantity or level of liquid in a container, for example of oil in the crank casing of a motor-car, is indicated by trapping a part of the liquid in a smaller chamber and utilizing the trapped column to limit the extent of movement of an indicating element. The measurement may be effected by lifting the column until an air vent is closed thereby or by moving a vented piston downwards into contact with the liquid. In the apparatus shown, the liquid-container 12 communicates trhough a passage 14 with the interior of a fitting 11 containing a piston 30 normally retained by a tension spring 37 below the passage 14. A branch passage 35 leads to the space below the piston. In the upper part of the fitting 11 is a float 24 normally resting on a disc 20 having an aperture 21 for the passage upwards of the liquid. When the piston is raised, the upper face of the float closes vents 23 to the outer air and thus limits the stroke of the piston. The float and disc are mounted in a detachable head member 22, which may be covered by a detachable cap 26 having fine vent holes 27. The piston may be raised by a handle 39, Fig. 3, on the shaft of a pointer 40 indicating the travel of the piston and thus the height of the column, the shaft carrying an arm 38 connected to the piston-rod by a cord 32. Where a vented piston moving downwards is employed, the communication between the bulk container and the trap is closed by a sleeve which is moved downwards by a spring as soon as the piston is pushed downwards. The piston in this arrangement may be held in the normal raised position by means of a spring connected to a lever joining the piston rod to the member 32 of the indicator. The indicator may be read directly from the position of the piston rod.

Patent GB-289163-A (GB)
Title: Improvements in or relating to remote control mechanism for indicating and other purposes
IPC: G01F23/50
Filed: 1927-01-22
Abstract: 289,163. Whitbourne, H. Jan. 22, 1927. Indicating.-In remote control mechanism of the type in which an inextensible flexible member is moved longitudinally within an outer stationary tubular member to transmit a pull or push, the inner member is simultaneously rotated for the purpose of reducing friction. The inner member preferably comprises superposed windings of closely coiled wire of which adjacent layers are wound in opposite directions and is an easy fit in an outer metal tube or pipe which may be bent as required. The material is preferably the same throughout to reduce errors due to changes of temperature. The inner member may be rotated continuously at relatively high speed by an electric motor, clockwork or a windmill, or it may be given partial or complete rotation by hand in the act of operating the remote control. To prevent creeping within the tube, short metal sleeves may be secured at intervals along the inner member, the spacing being irregular to render the device aperiodic. In an application to centrifugal speed indicators for use on aircraft, the flexible inner member 1, Fig. 1, is rotated continuously by a centrifugal device 3 of the governor type driven by the engine directly or through gearing, variations in speed causing longitudinal movements of the inner member which are indicated by a pointer 9 actuated through a pinion 13 and annular rack 11. In a twin engine control, transmission devices actuated by each engine coact with a single pinion 13 the axis of which is displaced when the speeds differ, such displacement being utilized to open or close the throttle of one or each engine.

Title: Improvements in or relating to time-bases
Inventor: ATTWOOD BRIAN ERNEST
IPC: H03K4/62
Filed: 1965-01-15
Abstract: 1,076,092. Transistor saw-tooth generators. MULLARD Ltd. Oct. 28, 1965 [Jan. 15, 1965], No. 2010/65. Heading H3T. A field time-base comprises a semi-conductor output stage (T2, T3), a saw-tooth drive circuit comprising a capacitor (C1) which is charged during the sweep and discharged during the fly-back and means for converting the drive into pulses the width of which is modulated in accordance with the instantaneous drive amplitude. In the circuit shown, the conversion is effected by a transistor T1 which is gated on by a ringing circuit LT, C6 tuned to an even harmonic of the line frequency. The output transistors operate in a highly efficient switching mode to amplify the pulses and these are smoothed by a circuit LF, C5 before application to the deflection coils LY. The sine wave from LT, C6 causes the pulse modulation to be non-linear but this allows exponential distortion to be compensated by adjusting RV2. Alternatively, increased efficiency may be obtained by making LT, C5 resonant also at the third harmonic of its fundamental frequency or by arranging that it saturates at sine wave peaks. The sawtooth and sine wave could be applied to the same electrode of T1 or the connections could be interchanged and T1 could be replaced by a gate-turn-off rectifier. SW could be a blocking oscillator or a triggered PNPN device. The output stage transistors are switched-off during the fly-back and the output circuit LY, C5 accordingly rings for half a cycle carrying the base of T3 negative through C3 and R4, thus helping to cut-off T3. However, the base of T2 is also carried negative of the supply rail and to avoid the resulting conduction of T2 a diode D1 is provided, the diode also allowing the coil voltage to be clamped at the end of the half-cycle (Fig. 6, not shown). A feedback winding from coil LF to the base of T1 would speed the switching and a resistor may be added in series with the base of T3 or emitter of T1 to avoid excessive base current, the resulting non-linearity being corrected by a resistor in the collector lead of T3. Transistors T2 and T3 may be of complementary type or may be replaced by gate-turn-off rectifiers and D.C. coupling may be provided between C1 and T1, as described in Specification 935,722.
