Title: Alloys and method of making same
IPC: C22C1/03
Filed: 1939-09-20
Abstract: 537,257. Alloys. BATTELLE MEMORIAL INSTITUTE. Sept. 20, 1939, No. 26274. Convention date, Sept. 21, 1938. Drawings to Specification. [Class 82 (i)] A method of making an alloy of two or more metals, particularly such as may be substantially insoluble in each other in the molten state comprises heating a parent alloy to such a temperature as to melt a low melting-point constituent thereof, and replacing this constituent with a different metal which is to form a constituent of the final alloy. The replacement may be effected by pressure or suction. For example silver may displace copper from an iron-copper alloy to give an iron-silver alloy; or bismuth may displace tin from an aluminiumtin alloy to give an aluminium-bismuth alloy, and so on. In some cases the operation may be carried out in two stages; for example an iron-tin alloy may be made from an ironcopper alloy by first displacing the copper by lead, and then the lead by tin. The production of the following alloys is referred to : iron with silver, bismuth, barium, calcium, magnesium, strontium, lead, and tin; nickel with silver, tin, thallium, and lead; aluminium with bismuth, cadmium, potassium, lead, and thallium; copper with lead, selenium, tellurium, thallium, and tin; silicon with lead and thallium; silver with selenium; beryllium with magnesium; and cadmium with gallium.

Title: Improvements in telephone systems
IPC: H04M3/523
Filed: 1950-10-31
Abstract: 685,337. Automatic exchange systems. GENERAL ELECTRIC CO., Ltd., and SCOWCROFT, J. Aug. 20, 1951 [Oct. 31, 1950], No. 26494/50. Class 40 (iv). A two co-ordinate wiper switch or distributer connects an incoming call to a marked outlet to a queue circuit, remains so positioned until the turn of the call to be answered arrives and then connects the call to an operator's position. Each distributer has two sets of wipers and twenty outlets per level. When a distributer is seized by a forward hunting switch, relay A steps the wipers to the first level, the outlets of which lead to queue circuits, and RH initiates rotary hunting. If all the queue circuits are busy, at the eleventh contacts AH, HA revert busy tone. If, say, wiper P1 finds an idle marking, AH, HA operate and RH releases, so energizing the rotary release catch magnet ZA. When the call having reached the head of the queue an operator is ready to take the call, battery is removed from the wiper P1, whereupon AH, HA fall back to energize the release magnet Z in series with the magnet ZA. The switch returns to a rotary normal position but does not fall back vertically. The rotary off-normal contacts NR release the magnets Z, ZA and operate the vertical magnet V and RH follows so that the switch hunts over the second level. Levels other than the first have outlets to operators' positions. On the eleventh contacts AH, HA release RH and the magnets Z, ZA return the wipers to the rotary normal position of the second level, the wipers then being raised and the search continued over the remaining levels. Should, say, P2 be successful, relay BH brings up HB which switches through to the operator's position and releases RH. A distributer having ten outlets per level and one wiper set may be used.

Title: Improvements in or relating to synchronising code patten detectors
Inventor: BRIGHAM ERIC RICHARD
IPC: H04J3/06
Filed: 1966-06-16
Abstract: 1,127,101. Electric selective signalling. MARCONI CO. Ltd. 20 March, 1967 [16 June, 1966], No. 26832/66. Heading G4H. Also in Division H4] An arrangement for detecting a code pattern of a predetermined sequence of bits, e.g. a synchronizing signal in a p.c.m. system, comprises a shift register having a number of stages which is less then the number of bits in a sequence, means for feeding the sequence to the register, means for shifting the register in steps, in each of which the register registers a different sub-sequence of bits, means for detecting the sub-sequences registered in the successive steps, a counter for counting the steps taken and for providing a pattern recognition signal when a count sufficient to permit registration of the whole pattern has been made, and means for resetting the counter if, at any step in the count, an incorrect sub-sequence combination is registered. As shown in Fig. 1, the synchronizing code, consisting of the sequence 1101010101010101, is fed to a three stage shift register 1 which is shifted step by step by pulses from a unit 2 which are also supplied to an AND gate 3. Three code detectors 5, 6, 7 are connected to the shift register so that they respond to the sub-sequences 110, 101 and 010 respectively. In operation, when the first combination is registered (110) the output of detector 5 switches a bi-stable device 9 which opens AND gate 3. The next pulse from unit 2 steps a 13-step counter via gate 3 and shifts register 1 by one step so that it registers 101. This combination is recognized by detector 6 thus inhibiting gate 8 from providing an output and enabling gate 3 to remain open. Counter 4 is stepped by the next pulse from 2 and the register shifted to register 010, this sequence being recognized by detector 7 so that gate 8 remains inhibited and gate 3 remains open. Detectors 6 and 7 continue to inhibit the gate 8 until the end of the synchronizing signal is reached, a full count is reached at 4 and an output signal is obtained indicating that the correct sync. signal has been received. Should an error occur in the sync. signal, detector 6 or 7 will fail to inhibit the gate 8, bi-stable 9 will be switched over to close gate 3, and the counter 4 will be reset to zero. The detector then awaits the registration of the 110 sequence to restart the count. In a modification, Fig. 2 (not shown), using the same synchronizing code, a two-stage register co-operates with a pair of detectors responding to 11 and 00 respectively. When the initial sequence 11 is detected a bi-stable device is switched to enable an AND gate controlling the counter which continues to count if the correct sync. signal is being received. Should the combination 11 or 00 be detected after the initial sequence a signal is provided via an OR gate to reset the counter.

Abstract: 888,617. Protective arrangements for variable-speed generators. MULLARD Ltd. Aug. 7, 1959, No. 27099/59. Class 38 (4). A circuit for detecting abnormal operation of a dynamoelectric machine comprises means for producing a signal dependent on the load current and speed, respectively, corresponding to the field current under similar normal conditions, the signal being compared with the actual field current, and any divergence between these quantities above a determined value actuating protective means. A permanent magnet tacho-generator develops across an inductance L2 a voltage proportional to the square of the speed, which voltage is rectified, amplified through transistors T36, T37 and applied to one control winding of a magnetic amplifier MA8, which controls the pulse duration of a square-wave supply BB applied to its main windings. A second control winding is fed with a voltage proportional to the load current. The output from MA8 is compared with the output from another magnetic amplifier MA7 also fed with a square-wave supply AA and controlled by a voltage proportional to the field current. The resultant output from the two amplifiers MA7, MA8 is fed to a further amplifier MA9 which is connected through a time lag circuit to a flip-flop arrangement T47, T48. When the resultant rises above a determined level the flip-flop operates a switching transistor which disconnects the field circuit. The resultant may alternatively operate an alarm. A pair of transistors T41, T42 effect correction of the amplifier MA8 characteristic in two stages as the machine speed decreases. Specification 844,591 is referred to.
