Title: Carrier frequency systems with main and stand-by phase-controlled oscillators
IPC: H04B1/74
Filed: 1975-03-27
Abstract: 1495419 Data transmission SIEMENS AG 27 March 1975 [9 April 1974 (2)] 13106/75 Heading H4P A carrier frequency system having main and at least one stand-by phase controlled oscillators each being connected to a local synchronization detector which also receives a common control frequency has oscillator disconnection switches with, on poles remote from the oscillator, an amplitude level detector with an output controlling its local sync. detector, each oscillator having an identical alarm and switch over unit controlled by the level detector comprising a first gate having an output to a first interconnection terminal and to a (NAND) second gate with commoned outputs to a first alarm effective when all oscillators are defective, a second NAND gate input being common to a third gate controlling the disconnecting switches, a second alarm being rendered effective to switch over to stand-by oscillator(s) on failure of any oscillator. Main oscillator OB of frequency harmonically related to a control frequency fst has its output monitored by synchronism detector SD, also receiving inputs from one or more stand-by oscillators OE of the same or harmonically related frequency also the control frequency fst, the output being passed through disconnecting switch UB to an amplitude level detection circuit G and common output terminal (unreferenced) to which other oscillators, provided with similar monitoring circuits are connected.  A common alarm A operates if both units become defective, or B on failure of the main oscillator which causes switch over. The alarm circuits comprise NAND gates 1,2,3, 6 with output terminals U-Z bridged in dependence whether an oscillator is main or stand-by, and manual reset key LT. In one modification, NAND gates 4, 5 are added as shown which avoid a switch over if any stand-by oscillator is disturbed. A second modification (Fig. 2, not shown) provides automatic reset by eliminating gates 6 and the B alarm circuit is connected through diodes to a common input to gates 1. Each sychronism detector may comprise an exclusive OR gate 10, Fig. 3, formed by NAND gates 16-19 having an output E fed via low pass filter 20 to a transistor switching stage 21, 22. The circuit is fed with the control frequency fst together with outputs from the phase discriminators of the oscillators through a plural input NAND gate 12 feeding a flip-flop 11 which may be synchronized by a pulse generator 24 formed by NAND gates 13-15. An alarm signal is generated in the event of non synchronism of any phase lock loop from any cause or a break in any connection line. Provision (not shown) is made to switch the band width of the low pass filter in phase control loops. Interference pulses may be suppressed by the insertion of a delay element in line A if the phase discriminators by themselves do not provide sufficient lag. The arrangement is particularly suited to I.C. phase controlled oscillators; certain NAND gates may be replaced by inverters.

IPC: G01P3/36
Abstract: 131,688. Hughes, A. J., and Hughes & Son, H. Aug. 1, 1918. Speed indicators operating by sighting torrestrial objects.-A device for measuring the angle of drift of aircraft on a particular course and for determining the ground speed comprises two concentric rotatable rings C, D mounted in a frame A which carries a lubber line B. The frame is mounted with the line joining the lubber line to the centre of the rings parallel to the fore-andaft axis of the aircraft. The outer ring C is graduated in degrees and the inner ring D carries an index E which is similarly situated in respect of two parallel cross-bars F, G or other device forming an observation slot. In use, the machine is set upon its course, the slot is rotated until the ground appears to move parallel with it, the angle of drift is then shown as the angle between the lubber line B and the index E. The ground-speed indicator comprises a sight hole II, capable of being fixed centrally, and situated above a linear scale F. This scale may be considered to have been made as follows:-At a known height an observation is made as to the apparent distance along the bar F a fixed point on the ground moves from the line PP in time t and a corresponding mark is made on the scale. This procedure is repeated for varying heights the speed of the aircraft being say 100 miles per hour. The scale is used thus:-Knowing the height of the aircraft, a pointer .1 is moved to the corresponding division of scale F. A pointer K is then placed opposite the line PP and the observer then causes the pointer K to follow a fixed point on the ground for time b. The speed in miles per hour then equals 100 X distance of K from P / distance of J from P

Patent GB-581035-A (GB)
Title: Improvements in or relating to the manufacture of vinyl cyanide
Filed: 1944-07-13
Abstract: Vinyl cyanide is prepared by the vapour phase reaction of acetylene and hydrogen cyanide in the presence of a catalyst comprising a cyanide of an alkali or alkaline earth metal supported on a substantially inert material of low surface activity, i.e. not capable of adsorbing large amounts of gases, for example carbon in such forms as wood charcoal, graphite, coke or coal, alundum, vitreous silica, beryl or metals such as chromium, aluminium, silver and gold which may be plated on to steel or other base metal.  Wood charcoal is the preferred support.  It may be heated, for example up to 700 DEG  C. for not more than 2 hrs., to remove volatile materials, but activation should be avoided by absence of oxygen, water vapour or other activating agent.  Alkali metal cyanide may be used as catalyst at a temperature not below its melting point, preferably 50-100 DEG  C. above the same, for example 500-700 DEG C., although temperatures down to 350 DEG  C. may be used.  A mixture of equal parts of sodium and potassium cyanides is preferred which may be dissolved in liquid ammonia and used to impregnate granules of wood charcoal, the solvent then being evaporated.  Such a catalyst is employed at 520-600 DEG  C.  The amount of cyanide is generally 5-20 per cent of the support, but may vary from less than 1 to 50 per cent. Materials forming cyanides under the reaction conditions such as alkali metal hydroxides, oxides, carbonates and borates may be used instead of preformed cyanides.  Double cyanides of alkalis or alkaline earths with heavy metals, such as sodium zinc, potassium copper, and potassium cadmium cyanides, are also applicable.  The cyanide may be diluted with fusible salts such as alkali metal halides, borates or carbonates.  Diluent gases may be added to the reactants, for example an excess of the latter, carbon monoxide, nitrogen, hydrogen or a hydrocarbon such as methane.  Vinyl cyanide is recovered by condensing and distillation.  In examples: (1) wood charcoal, devolatilized by heating to 1000 DEG  C., is broken to 3/8 " size and impregnated with 20 per cent of sodium cyanide, applied as a solution in liquid ammonia.  A mixture of 1 part hydrogen cyanide, 2 parts acetylene and 1.7 parts hydrogen by volume, preheated to 430 DEG  C., is passed through the catalyst, temperature increasing to and being maintained at 590-606 DEG  C., (2) temperature is maintained at 599-612 DEG  C., (3) equal parts of sodium and potassium cyanides are used in the catalyst and temperature is 595-615 DEG  C.

Title: Improvements in or relating to electronic decoding apparatus for decoding code numbers having various numbers of digits in telecommunications systems
IPC: H04M15/10
Filed: 1958-04-28
Abstract: 837,931. Automatic exchange systems. SIEMENS & HALSKE A.G. April 28, 1958 [April 26, 1957], No. 13485/58. Class 40 (4). In a system in which a register seizes a common translator after the receipt of each dialled digit and offers to the translator the digit(s) thus far received, if the digit(s) offered are insufficient for a translation to be effected, the translator applies operating voltage to a fast-acting relay in the register operation of which relay causes the register to release the translator. If, however, the digit(s) offered are sufficient, the operating voltage is suppressed, the translator operates one or more of a group of relays in the register in accordance with the required translation, and the operation of these relays brings up the fast-acting release relay. In Fig. 4, the elements above the chain-dotted line are part of a register and those below constitute the translator. The transistor T1 is normally conductive and upon seizure of the translator by a register applies operating voltage to the fast-acting release relay A. In considering the normal operation in response to a two-digit code, the circuits connected via W4 to the base of T1 will be assumed to be absent. The register offers digits to the translator by marking the relevant ones of leads S1, S2, S3 in respect of the first, second and third digits, respectively. If only one digit is offered no translation is effected and the operation of A follows. But when " 11," say, is offered, the AND-gate W11, G11 is opened and as a result the contacts s1 s2 are closed to operate the relays R1 and R3 in the register corresponding to the translation, and to connect -U1 to G1 and G3 of the OR- circuit G1 . . . Gn. The base of T1 thus becomes more positive than its emitter, and T1 is cut off before A can operate. If it is desired to measure the traffic to a particular centre having the code " 112," translation of "11 " is prevented by keeping T1 conductive when " 11 " is offered to the translator. This is effected by the AND-gate W12, G12 connected over d1, d2 to the leads S1(1) and S2(1) to which the marking voltage -U2 will be applied by the register. As -U2 is more negative than -U1, and W4 is substantially smaller than W2, the base of T1 remains more negative than its emitter, relay A is operated and the register releases the translator before R1 and R3 can operate. After reception of the third digit, the register again seizes the translator, and, as one of the leads S3 is now marked, transistor T2 conducts and applies its emitter voltage -U1 to G5 so that T1 is cut off and the translation is received by the register. If the call is to the centre "112," d3 connects S3(2) via G14 to the base of T3 and the AND-circuit W13, G13, G14 passes -U2 thereto, so that T3 conducts and operates counter Z to register the traffic to the centre.
