Title: Improvements in Wireless Direction-finding Arrangements.
Inventor: ROBINSON JAMES
Filed: 1918-11-04
Abstract: 134,342. Robinson, J. Nov. 4, 1918. Directive wireless signalting; bearings, determining wirelessly.-In a wireless directionfinder, a directive system is combined with a non- directive system in such a way that the intensity of the minimum signals observed is not zero as in the case when the directive system alone is used. The non- directive system superimposes a signal of constant value upon the signal of varying value received by the directive system, thus enabling any message included in the signals to be appreciated. In the arrangement shown in Fig. 4, a rotatable aerial coil 1 is connected through a reversing- switch 3 to a non-directive aerial 2 and tuning- condenser 4 in the detector circuit X. By operating the switch 3, the effects of the directive system may be added to, and subtracted from, the effects of the non-directive system, thus facilitating the determination of the minimum signal. The non-directive aerial 2 may be cut out of circuit and replaced by an inductance of equal value. The non-directive aerial may comprise a pair of fixed coils at right-angles to each other. The rotatable aerial 1 may be replaced by the moving coils of a radio-goniometer, of which the fixed coils are connected to two fixed directive aerials in the usual way. The Specification also refers to known arrangements in which two coils at right-angles are rotatably mounted on a vertical axis, means being provided to reverse the connexions between the two coils, which are adjusted until there is no change in the intensity of the signal on reversing the connexions. The Provisional Specification refers to several alternative arrangements of the non-directive aerial system.

Filed: 1935-06-24
Abstract: 459,050. Mechanical toys. SCHMID, M., 80A, Furtherstrasse, Nuremberg, Germany. June 24, 1935, No. 18082. [Class 132 (iii)] A toy vehicle or figure comprises steering mechanism for causing the vehicle to travel in a straight line or a curve or in contact with the edge of a surface or for preventing it falling over the edge of a surface. The vehicle a, Figs. 1 and 2, has a running wheel e keyed on the rear axle d driven by a spring motor b, a rear wheel f loosely mounted on a separate stub axle g, a front wheel axle h mounted in vertical slots i in the vehicle body, a rigid support l arranged out of the longitudinal axis of the vehicle and extending a shorter distance from the bottom plate k than the running rims of the wheels e and f, and two rod-shaped feelers n and n<1> frictionally adjustable at the two ends of a transverse bar m simulating the front buffer. The vehicle is weighted at c or the motor is arranged at the rear. If the feelers n, n<1> are raised, the vehicle moves in an arc on the track surface, Fig. 5, whilst if the feelers are lowered to slide on the track the vehicle runs in a straight line until it reaches the edge p of the surface o<1> when it is turned, Fig. 8. If only one of the feelers n<1>, Fig. 9, is lowered and the vehicle is placed on the support l with the feeler n<1> overhanging the edge of the track, the vehicle will run along the edge as it tends to perform an arcuate movement as shown in Fig. 5. In the construction shown in Fig. 10, the rigid support l is replaced by a lever q pivotally mounted on a pin r above the bottom plate k. If the lever q hangs down its face t comes into contact with the plate k and it acts like the rigid support l whilst if the lever q is swung inwards and held, the vehicle travels in a straight line.

Title: Improvements in or relating to the manufacture of transistors and other semi-conductor devices
IPC: H01L21/3063
Filed: 1957-06-07
Abstract: 825,494. Semi-conductor devices; electrolytic etching. TELEFUNKEN G.m.b.H. June 7, 1957 [July 16, 1956], No. 18180/57. Classes 37 and 41. A thin semi-conductor wafer is prepared by etching the surface of a semi-conductor body to form a depression, forming a PN junction and applying potentials across the PN junction and across the interface between an electrolyte and the depression surface so that the wafer is eroded to a desired thickness at which the direction of the etching current is reversed stopping further etching. In place of the initial etching to form a depression, the body surface may be illuminated during the electrolytic etching process, to promote etching in the central region. Fig. 1 shows an N-type semiconductor body 1 with a central depression in a conductive container 3 with insulating layers 2. A negative voltage (e.g. five volts) is applied to electrode 5 with respect to electrolyte 4, and minus 20 volts are applied to electrode 7 which forms a PN junction with body 1. A space charge layer 6 results from the reverse biasing of the PN junction. The semi-conductor is etched away until the electrolyte reaches the space charge region 6 where etching ceases due to the reversal of polarity. Metal salts may be added to the electrolyte so that a metallic electrode is deposited when this current reversal occurs. The smaller biasing voltage may be temporarily increased, or the PN junction bias temporarily reversed to increase the rate of etching. The semi-conductor may consist of germanium, and the wafer may be used for transistors.

Title: Improvements in or relating to circuit breaker reclosing mechanisms
IPC: H01H75/04
Filed: 1942-12-30
Abstract: 562,045. Automatic circuit-breakers. JOHNSON & PHILLIPS, Ltd., and BELLISS, W. H. A. Dec. 30, 1942, No. 18509. [Class 38 (v)] A circuit-breaker is adapted to be repeatedly reclosed pneumatically while a fault lasts, and is ultimately locked open by a thermal device heated during the periods when the breaker is open. The contact-actuating lever 7 is copivoted at 8 with a latch lever 9 to which it is normally locked by a toggle 10, 11 and trippable lever 12, which is notched at 12a to engage a pin 14 on lever 7. A further latch 15 engages lever 9 but is deflected by the toggle when, on overload, the coil 16 acts on lever 12, the linkage collapsing to a position in which lever 9 overlies a lever 19 and the toggle and latch lever 12 are reset. The tail of lever 9 engages a part 22 of a slidable rod 23 whereby movable contact 24 closes the circuit of a solenoid 26 which opens a valve 5 admitting air beneath the piston '3. Lever 19 is rotated about pivot 20 and by lifting lever 9 into engagement with latch 15, recloses the breaker, the switch 24 being reopened by lever 9 engaging the part 27 at the end of this movement. If the breaker trips out again, the next (and each subsequent) reclosure is retarded by the slow descent of piston 3 due to restricted exhaust port 28, which prevents the immediate reopening of valve 5. The initial reclosure may also be retarded by attaching lever 19 to lever 9 so that the piston is normally retained in its upper position. When the breaker is open, contact 34 on link 6 engaged contacts 33 to energize the heater 32 of a thermal switch 30 in series with the valvesolenoid 26. After a given number of reclosures, switch 30 opens and prevents further reclosures until manually reset by a push-button 44 on a reciprocating rod 43. A further pushbutton 45 on that rod can open switch 30 and mechanically trip the lever 12 or close a trip circuit 47 for coil 16. The heater 32 can be cut out, and reclosure effected, by a further push-button 37 having contacts 38 shunting the switch 30. Indicator lamps 31, 36 show the condition of a low air-pressure switch 29 and switch 30, respectively and lamps 40, 42 the open and closed condition of the breaker. The solenoid 26 may be controlled by an additional contact in dependence on the piston-position, and may electrically release the valve which is closed subsequently by the piston at the end of its stroke.

Title: Fuel cells
IPC: B01J47/12
Filed: 1962-05-14
Abstract: The electrolyte of fuel cells which becomes diluted in use by the formation of water, is reconcentrated by circulating it through an electrodialysis cell where the ions are drawn back into the fuel cell electrolyte and the water thus depleted is removed. For example, an outer wall of the fuel cell includes a perm-selective membrane communicating with a <PICT:1002419/C6-C7/1> chamber including an electrode, and into which excess of fuel cell electrolyte overflows, and by electrolysis, the dissolved ion recharges the fuel cell electrolyte.  The overflow may be operated by a float which when it rises to a discharge level operates a magnetic switch energizing the dialysis cell electrode.  A separate dialysis cell may be employed as in Fig. 4, where the fuel cell having electrodes D1, D2, is connected to the dialysis cell R2 by a conduit 1, and regenerated electrolyte is circulated by a pump P, dilute electrolyte passing into compartment R2, and the resulting ion-depleted water being discharged at valve 6.  Acid and alkaline electrolytes may be treated using cation or anion selective membranes, and salt solutions using both types of diaphragm in a 3-compartment cell. Electrolytic decomposition of the water itself may be effected by using a "gas" valve electrode, the surface of which is a porous catalytically active material e.g. as disclosed in Specification 931,778, the O and H produced being fed to the fuel cell units. Specifications 806,644, 909,459, 939,026, 960,479 and 985,239 also are referred to.

Abstract: 792,759. Sawing stone. ROUJON, A. L. June 15, 1956 [June 16, 1955], No. 18594/56. Class 124. Apparatus for feeding abrasive material to stone saws comprises a distributer tank associated with one or more settling tanks into which is delivered the excess liquid charged with slurries and abrasive overflowing from the distributer tank and in which the abrasive is deposited, the abrasive being evacuated into a sump into which fresh abrasive and liquid from the sawing operation are delivered. As shown, fresh abrasive, e.g., silicon carbide, is delivered by a conveyer c from a hopper a into a sump e in which liquid from the sawing operation is collected. The liquid is delivered from the sump to a distributer tank g by a conveyer h and the mixture supplied to the saws through pipes l and distributers m. Overflow from the tank g is fed to a separator n in which the abrasive settles to the bottom and the overflow may pass to a second separator o. The bottom of the separator is closed by a plug p3, Fig. 3, which may be raised by one or more pins p on a revolving disc q to discharge sediment through a pipe v to the sump e. The separator may be washed by a spray s, the valve r2 of which is opened at the same time as the plug is raised. When two separators are used they may be discharged alternately, twice per revolution of the disc q.

Levels, regulating.-Each bin or tank of a series supplied with pulverized coal, liquids, &c. from a common source is mounted on an elastic supporting member, the vertical movement of the bin, &c., as it is filled or emptied being utilized to cut off or open the supply pipe, and to give a signal to an attendant in charge of the supply. The bin 10 is carried by a frame 37 resting upon four cams 41, 42 fixed on shafts 47, 48 which are connected by arms 43, 44 and a rod 45 to ensure similar motion. A flange 15 on the shaft 47 is formed with a cup which rests upon a ball 46 attached to the spring 40. The vertical movement of the bin actuates a compressed air valve 20 by means of pins 32 on the flange 15, coacting with an arm 26 on the valve spindle which is turned suddenly as soon as the point of attachment of the-control spring 27 passes the neutral position. A device comprising a wedge-shaped spring plunger 29 coacting with a nose 30 also assists to complete the turning of the valve. The valve connects the pipes 23, 24 alternately to pressure and exhaust, thus controlling the movements of a motor 18, to which is attached the lever 13 of a valve 11, such as is described in Specification 122,825, [Class 135, Valves &c.], by which the material forced through the supply pipe 5 is deflected into the bin 10 or allowed to pass.
