Title: Improvements in automatic electric circuit-breakers
IPC: H01H73/30
Filed: 1950-06-26
Abstract: 684,868. Automatic circuit-breakers. MARCOZ, J. A. E. June 26,1950 [July 29, 1949], No. 15902/50. Class 38 (v) A trip-free circuitbreaker or switch has a pair of co-operating contacts 1, 2 mounted on spring blades 3, 4 normally biassed upwardly into the positions shown in Fig. 3. To close the switch, a push button 7 is depressed, the initial movement of the button moving a comparatively weak blade spring 6 down into engagement with the blade 3 and bringing a projection 11 of the button adjacent to the blade 4. As the downward movement of the button continues, the blades 6, 3 are moved until the blade 6 engages beneath a latch member 9. Just before the blades 6, 3 are latched, the projection 11 moves the blade 4 downwards, so that having latched the blade 3, it is necessary to release the button 7 before the contacts 1, 2 can be closed by the subsequent upward movement of the blade 4, thus rendering it impossible to hold the contacts closed under overload conditions. The latch member 9 is carried by a spring plate 10 connected by a insulated set screw 13 to a U-shaped bimetallic element 12. Distortion of the element 12 deflects the plate 10 to trip the switch. The direction of the current in the blades 3, 4 and the arms a, b of the element 12, Fig. 4, is such that the members 3, 4, a, b form a coil to blow out the arc formed between contacts 1, 2 when the switch is tripped.

Title: Improvements in or relating to discharge tubes
Inventor: LENZ KURT
IPC: H01J5/06
Filed: 1951-07-10
Abstract: A discharge tube electrode is provided with a very smooth solid operating surface by coating it with a substance containing metal, mounting it in its operating position in the tube, heating the substance so as to cause it to melt, and allowing it to solidify. Preferably a eutectic alloy is used which has a low vapour pressure for its component at the melting point; this may be an alloy of iron, cobalt or nickel with phosphorus or arsenic, preferably 89 per cent nickel and 11 per cent phosphorus.  These alloys have the additional property of "poisoning" any particles of emissive material which may fall upon them and this is useful in connection with grids of transmitting valves and thyratrons.  The substance may be applied as a paste or electrolytically and the melting is prefer ably done during exhaustion.  Such smooth electrodes are useful where subjected to high voltages, for example rectifier anodes and cathode shields of cathode-ray tubes, electron microscopes and X-ray tubes.

Title: Improvements in or relating to arrangements for converting numbers from a scale having a first radix to a scale having a second radix
Inventor: VOLES RODGER
IPC: G06F7/66
Filed: 1959-05-19
Abstract: 950,950. Digital electric calculating apparatus. ELECTRIC & MUSICAL INDUSTRIES Ltd. May 18,1960 [May 19, 1959], No. 16845/59. Heading G4A. In an arrangement for converting a number from one radix to another, an electric signal is generated representing each digit in the first radix without having regard to the order of the digit, a code signal in the second radix is generated in respect of each digit having regard to the order of each digit and said code signals are combined to provide the original number in the second radix. As applied to a differential analyser, such as that described in Specifications 948, 760 and 949, 196, a decimal number to be applied to the Y register is entered on the first level I 1  of a matrix 1. The resistors K connecting the level to the vertical conductors 10<SP>0</SP>-10<SP>M</SP> are inversely proportional to the digits corresponding to these orders. Clock pulses C1 connect the vertical conductors one-by-one to a summing amplifier 3 and converter 4. Thus at the first step the units digit is set up in 4 and applied in binary digital form to coincidence circuit 8. At the same time clock pulses C2 are applied to a counter R3 which completes a cycle in the time of one C1 clock pulse. At the end of each cycle a pulse is applied to counter 6. When the converter 4 and counter 6 are in agreement, i.e. after the units digit has been counted out, coincidence circuit 8 operates to inhibit gates G3, G4. Meanwhile a single rectifier connection between Bo and Do in matrix 5 has permitted the transmission of the binary equivalent of decimal unity to serial adder 7 a number of times equal to the units digit. The cycle then repeats in respect of the tens digit with appropriate rectifier connections in matrix 5 giving the appropriate weighting. When the complete number has been transferred an elementary integration takes place in the manner described in the abovementioned Specifications. Reference is also made to Specification 679,725.

Title: Improvements in and relating to aerial obstructions to aircraft attack
IPC: F41H11/04
Filed: 1939-06-09
Abstract: 529,871. Aerial warfare. PRESCOTT, S. J. June 9. 1939, No. 16984. [Class 9 (ii)] Aerial suspensions for anti-aircraft defence comprise a flexible obstruction closed up in a parachute so that it can open while falling by its own weight and descend slowly with the open parachute. The obstruction consists of two or more strips of fabric 6, e.g. upholstery webbing. each connected at one end to a bar 8 and at the other end to a bar 7, the strips being rolled on the bar 7 so that the whole obstruction may be accommodated within a hollow cylinder 1 of cardboard, celluloid, metal &c. The bar 8 is connected by a loop 9 to a cord 10 connected to a cap 2 on the cylinder 1, so that when released the bar 8 may fall clear of the cylinder. The parachute 4, which is carried by ribs 3 pivoted on the cap 2, is folded about the cylinder 1 where it is held by a band 12 able to be snapped by the pull of a cord 13 connected to the bar 7. When the apparatus is launched, by falling down an inclined runway or through an opening in an aircraft, the bar 7 with its fabric rolls falls relatively to the cylinder and tensions the cord 13 which then breaks the band 12, whereupon the parachute opens to check the fall of the bar 7 and thus allow the obstruction to unroll. A pilot parachute may be provided. The fabric obstruction may be coloured to reduce its visibility.
