Title: Clock pulse generating equipment
IPC: G11B20/14
Filed: 1958-09-12
Abstract: 857,955. Synchronizing arrangements for data-storage apparatus. STANDARD TELEPHONES & CABLES Ltd. Sept. 12, 1958 [Sept. 13, 1957], No. 29259/58. Class 106 (1). In equipment for generating clock pulses in synchronism with an irregular train of information pulses, e.g. read from or to be written on a magnetic record, a pulse generator is stopped in response to each information pulse applied to the input and is started or restarted in response to a corresponding delayed pulse. As shown in Fig. 1, the pulse generator comprises an LC delay network LZK2 and a feedback path comprising AND gate U1 and OR gate O1. Each information pulse at a is applied to delay network discharge switch 2 and to bi-stable flip-flop FF which is switched over so as to close gate U1 and open gate U2; the pulse is also delayed in network LZK1 and then applied through pulse shaper 1 to reset FF and through gate U2 to network LZK2. The outputs of both delay networks are combined in OR gate 02 to form the required clock pulse train. In the circuit shown in Fig. 2, the pulse generator comprises a multivibrator MV2 which is normally free running to produce clock pulses at the required frequency at output g, but is stopped when FF is switched over by an information pulse at a and is started again after a delay determined by one-shot multivibrator MV1. If multivibrator MV2 is tuned to produce output pulses with a period T, MV1 will have a restoring time of T/2. A detailed circuit diagram is given in which MV1, MV2 and FF each comprise a crosscoupled pair of PNP transistors.

Abstract: 1,059,823. Error-correcting arrangemenst. CODEX CORPORATION. July 24, 1963 [July 25, 1962], No. 29359/63. Heading G4A. An error-detecting and correcting arrangement for transmitted binary data comprises as shown, a convolution code check bit generator 2 comprising 2-bit delay units 3, 5, 7, 9, 11, a modulo-2 2 adder 19 and a 1-bit delay 21, information bits arriving at 2-bit intervals being alternated on output line 17 with check bits derived from the last 6 information bits received. At the receiver a switching circuit directs the information bits to line 8 where they enter a replica of the check bit generator 2, and the check bits to modulo-2 adder 14. If the re-computed check bits do not correspond an output appears on line 16. In the example described, not all the connections g<SP>1</SP>, g<SP>11</SP> to adders 19 and 19<SP>1</SP> are effective; according to which are effective, an error function is formed consisting of a series of bits fed into delay units 3<SP>11</SP>-11<SP>11</SP>. When the firstreceived information bit reaches the output of chain 3<SP>1</SP>-11<SP>1</SP> a decision must be taken, on the basis of the error function bits in 3<SP>11</SP>-11<SP>11</SP>, as to whether it is in error or not; this decision is taken by a threshold circuit 36 controlling modulo-2 adder 27. The theory behind the choice of an error code, and the realization of threshold circuits, is given in detail, and further applications to block linear codes are discussed and illustrated. Specification 1,059,824, divided out of the present Specification, and relating to similar arrangements for diffuse codes, is referred to.

Abstract: 669,526. Making footwear and lasts therefor. MURRAY, A. E. Nov. 21, 1949 [Jan. 8, 1949; May 14, 1949], Nos. 29705/49 and 29706/49. Drawings to Specification. Classes 17 (i) and 17 (ii). [Also in Group V] On a stiff monitor sheet of non-shrinking material such as cardboard, having, in outline, the shape of a foot for which the footwear is required, a dish of plastic material following the outline of the sheet and shaped to the underside of the foot, which rests on it, is built up and to it a cover or upper of plastic material conforming to the contours of the upper part of the foot is attached. The cardboard may be removed, after danger of shrinkage has passed, and a sole applied, or it may be left in position. The dish and the cover or upper are both built up by successively applied layers of thick loosely-woven fabric known as monks cloth brushed with selfvulcanizing latex. Burlap and terry cloth may be used for some of the layers. Thick latex and finely divided fibrous materials or rags are worked under the arches of the foot as it rests on the layers. A slit is made in the front of the upper to admit the foot, while the materials are still soft, and the shoe allowed to take up the mobile form of the foot i.e. when in action in walking. After using the form in this way for some time, a cast is made of the modified form, from which a shoe may be built. Such shoe may be built up from layers of monks cloth coated with latex and may have a tongue which is level with the upper. Before making up the shoe the casts may be modified in any way desired-e.g. in length or in foot depth by adding or removing material.

Title: Improvements in or relating to gun mountings
IPC: F41A27/30
Filed: 1954-10-15
Abstract: 822,003. Gun mountings. WEBSTER, T.H. Sept. 26, 1955 [Oct. 15, 1954], No. 29715/54. Class 92 Relates to a gun mounting designed to correct the out of balance produced by the gun during its time of recoil and run out. According to the invention for guns firing at small angles of elevation the trunnion axis is positioned above the centre of gravity of the recoiling parts at such a distance x, Fig. 19, that the pull of recoil and subsequent run out forces produce a couple about the trunnion axis tending to depress the gun muzzle in opposition and approximately equal to the couple about the trunnion axis produced by recoiling parts as they slide' rearward in recoil and tending to elevate the gun muzzle. For guns firing at angles of elevation greater than about 20-25 degrees a different arrangement is necessary. In this -case each trunnion pin 1, Fig. 14, is secured to the cradle 2 and carries a toothed arc sector 3 of radius x, Fig. 13, which meshes with a toothed arc 4 on the underside of the trunnion cap 5. The bearing part 6 of each trunnion is carried at the upper end of a link 7 pivoted on a pin 8 on the side of the carriage cheek 9. As the gun elevates or depresses the toothed arc sector 3 moves forwards or rearwards. The pitch line of the teeth of each sector 3 are arranged at the distance x in relation to the trunnion axis so that equal and opposite couples are set up during recoil and run out. Fig. 17 shows how the gun is elevated when this recoil balancing device is used and when power elevating is necessary. An elevating arc 10 is pivoted on a cross shaft 17 in bearings 11 on the carriage cheeks 9, the axis of this pivot being a suitable distance from the trunnion axis 1. The arc 10 is moved in elevation by a power-operated pinion 12 and actuates the gun by links 13, the upper end of each link being carried on a pin 14 secured to the gun casing 2 while the lower end is secured to the arc 10 by a pin 16.

Title: Improvements in or relating to the process of producing a mixture of isomeric chloropentenyl ethers
Filed: 1950-12-07
Abstract: A mixture of 5-chloro-3-pentenyl ether and 3-chloro-4-pentenyl ether obtained by reacting at least two moles of butadiene with one mole of chloromethyl ether (see Group IV (b)) on reaction with an inorganic cyanide appears to yield only one dinitrile which on hydrolysis yields a dicarboxylic acid which may be used for the manufacture of alkyd resins.  The mixture of isomers may also be reacted with an aqueous solution of an alkali carbonate to yield a mixture of isomeric glycols which react with polycarboxylic acids, including that described above, to form linear polyesters or alkyd resins.  The mixture of isomers can also be converted readily into a mixture of isomeric diamines which react with dicarboxylic acids including that described above to form linear polyamides.ALSO:A mixture of 5-chloro-3-pentenyl ether and 3-chloro-4-pentenyl ether is obtained by reacting at least two moles. of butadiene with one mole. of chloromethyl ether at a temperature of 0-50 DEG  C. in the presence of a mild Friedel Crafts catalyst such as zinc chloride, mercuric chloride, ferric chloride, bismuth chloride or antimony chloride.  If desired the process may be carried out at superatmospheric pressure of up to 100 pounds per square inch.  It is preferred to carry out the process in the presence of a solvent especially glacial acetic acid.  The two isomers can be separated by fractional distillation, but this is not usually necessary since the mixture of isomers on reacting with an inorganic cyanide appears to yield only one dinitrile which may be hydrolysed to a dicarboxylic acid.  The mixture of isomers can also be reacted with an aqueous solution of an alkali carbonate to yield a mixture of the isomeric glycols which or can be converted to a mixture of isomeric diamines.  The dicarboxylic acids, glycols and diamines may be used for the production of polyamides and polyesters (see Group IV (a)).  An example is given for the production of the isomeric mixture, the reaction being carried out in the presence of zinc chloride using glacial acetic acid as solvent and using 3 moles. of butadiene per mole of chloromethyl ether.  It is stated that when various mixtures of the two isomers are treated with a catalytic amount of zinc chloride the two compounds form an equilibrium mixture containing about 85 per cent of 5-chloro-3-pentenyl ether and about 15 per cent of 3-chloro-4-pentenyl ether.
