Title: Improvements in or relating to processes for the manufacture of semi-conductor rectifiers
Inventor: BLANKS HENRY STANLEY
IPC: H01L21/24
Filed: 1955-07-28
Abstract: 797,687. Semi-conductor devices. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. May 28, 1956 [July 28, 1955], No. 21831/55. Drawings to Specification. Class 37. A method of making a PN junction rectifier comprises the following steps: placing a pellet of activator material characteristic of one conductivity type on a semi-conductor wafer of the opposite type, heating in vacuo or in an inert atmosphere to a temperature slightly above the melting-point and wetting temperature of the activator, forming an oxide skin on the activator, raising the temperature to the optimum temperature for alloying, and then cooling. In the embodiment an indium pellet is placed on a germanium wafer mounted on a nickel baseplate, and heated in a flow of oxygen-free hydrogen to 300  C. The flow of hydrogen is then replaced by a flow of nitrogen containing some oxygen and the assembly raised to the optimum alloying temperature of 510 C. The assembly is then cooled and, if desired, the oxide layer is removed from the indium by etching. The effect of the oxide film is to raise the surface tension so that the uncontrolled spread of indium over the germanium surface which would otherwise occur at the optimum alloying temperature is avoided. Sufficient oxygen may be introduced into the nitrogen by bubbling it through water. The method may also be used in alloying an antimony pellet to a wafer of silicon.

Patent GB-673332-A (GB)
Title: Improvements in or relating to the method of producing hydrogen
IPC: C01B3/30
Filed: 1950-09-06
Abstract: <PICT:0673332/III/1> Hydrogen is produced by circulating a hydrocarbon in gaseous phase, e.g. methane, ethane, propane, butane, vaporized liquid hydrocarbons, or gases from cracking liquid or solid hydrocarbon materials such as coal tar pitch, and steam in concurrent intimate contact through a reaction zone containing barium oxide in graular form, maintaining the reaction zone at 1700 DEG -2300 DEG F. and at least 1 atmosphere absolute, the amount of oxide being sufficient to absorb substantially all the carbon dioxide produced, the minimum pressure being about 1 atmosphere for the range 1700 DEG -2050 DEG F. and being related to the temperature for the range 2050 DEG -2300 DEG F. by empirical equation: p=1+4.9x10-2 (t-2050) where t is the temperature, and recovering the gaseous product.  In a cyclic process using three reactors steam from 42 and methane from 44 in proportions 2 : 1 to 4 : 1 are mixed and fed by pipes 46, 54 downwardly through freshly regenerated preheating fixed bed of barium oxide at 2300 DEG -2350 DEG F. on porous plate 38 in reactor 32. Some reaction occurs and heat is liberated by the barium oxide-carbon dioxide reaction, which establishes a temperature gradient of at least 100 DEG F. downwardly in the bed.  The gases pass thence by pipes 64, 66 upwardly through fixed bed of barium oxide, say at least 800 parts BaO per 100 parts carbon in the methane, or porous plate 40 in reactor 34, which has a temperature gradient of at least 100 DEG F. already established by use of reactor 34 as preheater in the preceding cycle.  Hydrogen is withdrawn through pipe 78 cyclone 84, pipes 96, 102 and 98 through steam preheater to produce.  The bed in reactor 30 which was used for hydrogen production in the preceding cycle is simultaneously regenerated under fluidized conditions at atmospheric pressure and 2300 DEG -2350 DEG F. by burning producer gas entering at 150 with air entering at 162.  Waste flue gases are withdrawn through line 74, cyclone 80, and line 114 through a steam/methane feed preheater. The producer gas is obtained by passing coal from hopper 126 and steam from line 134 into reactor 138, while injecting air at 142; the producer gas is withdrawn through line 144 and cyclone 146 to line 150.  The pressure in the reactors 32, 34 is controlled by valve 112 in line 98, and optimum conditions are 1700 DEG -2050 DEG F. at 20-50 atmospheres.  The particle size of the barium oxide should be -20 to +200 mesh so that at a gas velocity of 0.03-0.3 ft./sec. in reactor 34 the bed is unfluidized while at a gas velocity of 1-4 ft./sec. in reactor 30 the bed is fluidized.  The temperature is maintained in reactor 34 by the BaO-CO2 reaction, but additional heat may be supplied, if necessary, by external heating or by combustion of carbonaceous material.  The compound BaO BaCO3 is preferred to BaO as it has a lower regeneration temperature.  An apparatus using a single reactor is also described.

Title: Improvements relating to data transmission systems
IPC: H04L1/20
Filed: 1965-05-24
Abstract: 1,112,536. Data transmission systems. TELEFONAKTIEBOLAGET L. M. ERICSSON. 24 May, 1965 [28 May, 1964], No. 21988/65. Heading H4P. A system for reducing the effect of noise on a received differential coded signal comprises means for inverting a decoded bit if the time integral of a differential bit lies below a given threshold, whereby double faults which would otherwise appear are reduced to single faults. In the embodiment described phase-modulated signals are demodulated and the resulting polar differential signal passes to integrators which integrate the positive and negative voltages occurring in a bit period. The difference of the integrals is determined at the end of each bit and operates a toggle except when the difference is small,,i.e. when a bit is mutilated and its state cannot be confidently determined. The toggle feeds a two-bit register which gives a parallel signal to a gating arrangement. The integral difference, after rectification, passes to a threshold unit set to a level below which the bitstate is indeterminate, this unit passing only those difference pulses which exceed that level to operate a flip-flop which feeds the gating arrangement. The gating arrangement decodes the differential signal and produces simple binary signals. When an error has been detected by the threshold loop the gating arrangement provides an inverted bit, such bit being the second bit of a faulty bit-pair resulting from the mutilated differential bit.

Abstract: 887,586. Circuits employing bi-stable magnetic elements. PHILIPS ELECTRICAL INDUSTRIES Ltd. July 11, 1958 [July 12, 1957], No. 22319/58. Class 40 (9). [Also in Group XIX] A pulse frequency dividing circuit comprises a pair of cores A, B, Fig. 1, each having two windings WA1, WA2 and WB1, WB2, the turns of which are dissimilar, the windings WA1, WB1 being connected in series in the same magnetizing sense to a source of negative pulses NG, while the windings WA2, WB2 are connected in series in opposite magnetizing senses to a source of positive pulses PG, a third winding WA3 acting in the same sense as winding WA1 on core A being also connected to the positive pulse source. The pulses PG, NG may be derived from a common input and are applied alternately, the winding with the larger number of turns in the relevant series path taking priority in reversing the magnetic state of the associated core, if the state is such as to be reversible. A reversal of state of a core limits the current in the series path so that the magnetic state of the other core is unaffected. Assuming that the cores are both initially in state " 0," then a sequence of core reversals takes place as shown in Fig. 3, the winding WA3 being operative during the first positive pulse to switch core A to state " 1 " and during the second positive pulse to inhibit switching of core A by current in winding WA2. A single output pulse for a total of two positive and two negative input pulses may be derived from windings (not shown) on each core. Alternatively, outputs may be taken from a terminal UA, UB or UK. In a modification, Fig. 4, an additional core C with windings WC1, WC2 respectively connected in the two series paths is provided. In this arrangement a resistor R3 is provided across which a switching voltage is developed at the stage when the impedance of winding WC2 is low to a positive pulse. The two pulses in this case are provided by an alternating supply over respective rectifiers G1 and G2. The pattern of core switching as the application of pulses proceeds is shown in Fig. 5. Output windings (not shown) may be provided on cores B and C or outputs may be derived from resistors in series with windings WA1 or WA2.

Abstract: 381,277. Roasting grain. CRETORS, C., 620, West 22nd Street, Chicago, U.S.A. Aug. 8, 1931, No. 22512. [Class 58.] A corn-popping apparatus comprises a stationary support having mounted thereon in an invertible manner, a shallow open-top popping-pan and associated heating-unit located near the bottom of the pan, the pan having a rotary stirring means therein and a cover carried by, a swinging arm which has a pivotal connection with the stationary support and which is provided with means tending constantly to move the arm upwardly and a latching means adapted to hold the arm and cover in downward position, said latching means having an operative connection with the pan cover effecting release of the latch on an initial upward movement of the cover. A tubular support 1 carries and communicates with sleeves 3 on which are mounted the heater elements and popping-pans. Burners 13 are enclosed by walls 14, 14<1> and deflector plates 12 to throw an annular zonal flame on the pans 15. Each heater unit is loosely mounted on a shaft 30 having driven connection with a shaft 6, driven through gearing 5 from a shaft 4, through a manually-operated clutch 35 and bevel gears 34. The shaft 30 is detachably connected to an annular neck 10 of the central casing 7 of the heater unit by studs 22 and a deformed annulus 21, and is further supported by brackets 23. The cover 39 is provided with a central guide sleeve 40 in which a carrying stem 41 has limited independent movement, the said sleeve and stem being connected by a helical rib and groove formation 42 so that after the cover has been raised to a certain distance it no longer rotates with the stem 41. The said stem is clutched to the stirrer unit by means of a sleeve 43, elongated slots in which engage a cross pin 31 on the stirrer unit. When the corn expands, the cover is initially retarded by friction and moves upwards under the action of the rib and groove formation 42, such movement releasing a rocker bar 48 from an abutment 50 so that the arm 44 carrying the lid may move upwards under the action of the spring 47, so releasing the clutch 31, 43. The pans are then inverted by means of the handles 54 for which purpose each sleeve 3 is in sliding engagement with the neck 2 of the pedestal 1 ; each pan is maintained in its popping position by a spring- impelled bolt 51 engaging a depression in the sleeve 3. Gaseous 'fuel is supplied to the burners through the support 1 and sleeves 3, 7 or may be supplied through extensions 3<1> of the sleeves 3.
