Title: Coded electric signal recognition circuits
IPC: G06F7/02
Filed: 1958-01-28
Abstract: 856,729. Electric selective signalling systems. RADIO CORPORATION OF AMERICA. Jan. 28, 1958 [Jan. 31, 1957], No. 2880/58. Class 40 (1). A word recognition circuit (for example for use in a paging system) is described in which a word to be recognized is shifted serially into a magnetic core recognition register which is then " tested " to determine whether the word is that which the register is designed to recognize or not, this being effected by means of one additional coil on each core, the coils being seriesconnected and so poled that their series impedance is substantially zero only when that word which is to be recognized is in the register. A word to be recognized, 61, Fig. 2a, comprises a series of fourteen positive and negative pulses followed by a long pulse. The word is received by a device 11 and amplified and inverted by a transistor 30. Resulting positive pulses (ones) then pass via a diode 82 to cause firstly a one to be entered by a transistor 31 into the first core of a 16-core register 16 and secondly after a short delay, caused by a core 35, shift of the contents of register 16 by a transistor 33, while resulting negative pulses (zeros) pass via diode 135 direct to transistor 33 to cause shift of the register 16 only. When the long pulse is received at the end of the word it is inverted and causes shift of the register 16 (this results in the fourteen bits of the word being in the right-hand fourteen cores of the register, the first two being in their zero states) and also passes to an integrating capacitor 161, Fig. 2b, where, by virtue of its duration, it causes a transistor 52 to produce a test pulse which passes via the seriesconnected test coils on leads 189. If the word received is that which the register is designed to recognize the series-connected test coils present a very low impedance to the test pulse and the result is that a flip-flop 55, 56 is changed over to energize a warning device 22 (e.g. buzzer or lamp). If the word received is not that which the register is designed to recognize, then the warning device is not energized.

Abstract: 1,179,161. Automatic position control. VICKERS Ltd. Jan.12, 1968 [Jan. 20, 1967], No.3230/67. Heading G3R. In an electron beam welding system, power is reduced and the beam scanned transversely to the weld periodically so that any error in the mean position of the beam is detected by the timing of secondary emission from the weld line which is utilized to correct the beam position automatically. In Fig. 1, two plates 1a, 1b are supported on a continuously moving trolley 22 in a vacuum chamber 21 so that they are welded together along a line 2 by an electron beam 3 from a gun 4. At intervals determined by a programmer 12 the gun is biased to reduce power and deflecting coils X, Y energized by a generator 11 to move the beam slightly ahead in the welding direction to a point 15 and then to scan an area 14. The increase in secondary emission each time the beam crosses the abutment is detected by a Faraday cage 6 and compared with the time at which the scan is central when a unit 7 is gated by programmer 12. Any difference, representing error in the mean position of the beam, produces a voltage at 8 which is applied to deflecting coils 5 or Y to correct the error in readiness for the next welding interval at full power. Signals from unit 7 and scan generator 11 are applied to a television type display 9 and a cathode ray tube 10 which indicate the position of the abutment. A modification, more suitable when the welding line is not straight, in which the electron beam is scanned once instead of several times, is described.

Title: Improvements in the manufacture and production of hydrocarbons of low boiling point from those of higher boiling point
IPC: B01J8/20
Filed: 1929-02-01
Abstract: 328,649. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Feb. 1, 1929. Hydrocarbons, cracking and distilling; hydrogenation, destructive.-In a process of cracking high boiling point hydrocarbons, such as tars, mineral oils &c., in the presence of a solid catalyst, which maintains its shape under the conditions of working, e.g. bauxite, silica gel &c., the deterioration of the catalyst by the deposition of carbonaceous material thereon is minimized by the intermittent or continuous withdrawal of some of the liquid being treated together with its contained catalyst, separating this from the liquid, which may be returned to the reaction chamber, and regenerating the catalyst for further use. Separation from the catalyst may be effected bv distillation, filtration, extraction by a solvent, by centrifuging or by a combination of these methods. Removal may be effected by a valve at the bottom of the reaction chamber or, when the cracking is carried out under pressure, removal and re-introduction are effected by means of a pressure lock, the withdrawal being made before there is any substantial deposition of coke on the catalyst. Reduced or increased pressure may be employed, e.g. 10 to 100 atmospheres or more, and extraneous gases, such as hydrogen, nitrogen, water vapour and gaseous hydrocarbons such as methane, may be introduced at temperatures between 350‹ and 650‹ C. In an example, gas oil with 3.5 per cent of finely ground bauxite is preheated to 420‹ or 430‹ C. at a pressure of 50 atmospheres and introduced into a reaction vessel from which the volatile products are withdrawn. A part of the liquid with its contained bauxite is intermittently or continuously withdrawn through a vertical tube. The volatile constituents of this portion are distilled off, or the liquid is separated by filtration &c., and the adherent matter removed from the bauxite by combustion, the heat so generated being used for preheating the oil. The regenerated bauxite, ground if necessary, is returned to the reaction chamber. Specifications 5245/13, 189,200, 326,157, and 326,184 are referred to.

Abstract: 737,808. Recording and integrating apparatus. INSTITUT DE RECHERCHES DE LA SIDERURGIE. Feb. 9, 1953 [May 14, 1952], No. 3561/53. Class 106 (4). [Also in Group XXXVIII] The rates of fluid flow in two or more pipes are summed, or percentages thereof are summed, and recorded against total flow, the recording chart being advanced at constant speed in steps of variable duration so that its displacement over an extended time is proportional to total flow. The invention is described for recording the rate of flow of oxygen and rate of flow of total blast, i.e. air plus additional oxygen, in a refining pig-iron Thomas converter. The air and oxygen flows in the respective pipes A, O, Fig. 1, are measured in U-tube or ring-type meters 1, 2, the measuring arms 9 of which drive through cords 11, pulleys 12, and gearing 14, 15, Selsyn transmitters 3a, 4a, 3b, 4b. The transmitters 3b, 4b are differential Selsyns, Fig. 2 (not shown), and cascade connected with the respective transmitter 3a, 4a to summate the corresponding readings, and the gearing 14, 15 is arranged so that the receivers 5, 6 set by the usual servomotors 19 responsive to the error voltages register rate of flow respectively of total blast, i.e. air plus oxygen and total oxygen, i.e. oxygen plus 0.208 of the air flow. Recording mechanism. Each servomotor 19, Fig. 3, drives the associated recording pen 21 in accordance with the corresponding fluid flow rates, and also drives a cam 22 having a semicircular portion 23 of enlarged radius. A similar coaxial cam 24 is fixed. A disc 26 driven at constant speed by a motor 29 carries a spindle 28 on which are secured rockers 28a coacting with the cams 22, 24 to open a microreverser switch 27 also carried by the disc 26, when the cam portions 23, 25 of greater radius are operative. The micro-switch 27 is thus closed for a variable time during each rotation of the disc 26 dependent on the angular position of the cam 22, and energizes a clutch 31 so that during these periods the record chart is advanced by the motor 29. Over an extended time interval the chart advance is thus in accordance with the integral of the rate of flow, i.e. in accordance with the volume flow.
