Title: A textile ring spinning, twisting, doubling or like machine having a donning and doffing device
IPC: D01H9/04
Filed: 1956-04-13
Abstract: 854,968. Donning and doffing apparatus for ring spinners &c. SCRIVEN, F. W. A. July 15, 1957 [April 13, 1956], No. 11307/56. Class 120(2). A donning and doffing device in a ring- spinning &c. machine comprises two sets of cop-gripping means, each of which can be moved into and out of engagement with caps on the spindles, one set being adapted to grip full cops and having at least one yarn gripper for each cop and the other being adapted to grip empty cops; there is a yarn holder on each spindle of the machine so that when the doffing device is employed, the yarn is held by the yarn gripper and the yarn holder, so that the yarn breaks between the two. In Fig. 2, the donning-device 12 and the doffing device 10 comprise a framework carried on a shaft 14 which can be rotated by a handle 56 and moved up-and-down by rotating a handle 72 ; the device 12 consists of rails 36, 38, connected together and to the shaft by bars 40, and the device 10 of rails 24, 26 connected similarly by bars 28. At each position corresponding to that of the machine spindles the rail 26 has a clip 30, a fork 32 and a guard 34, Fig. 4, while at corresponding positions on the rail 24 is a series of catch-members 35. Each spindle has a disc 74, Fig. 7, with a groove 76 and three notches 78. When the spindle-rail is lowered prior to doffing, a few turns of yarn are wound in the groove 76. The lappet rail 17 is tilted backwardly and the frame lowered until the guards 34 push aside the yarn passing to the spindles and the forks 32 are just below the cops and the members 35 engage the tops of the cops. The shaft 14 is then turned so that the clips 30 grip the cops ; when the frame is raised, the cops are withdrawn by the clips and the forks, and the thread, being caught between the notches 78 the clips, are broken. The rail 38 of the donning- frame has clips 42 positioned to correspond with the spindles, and a bar 44 hinged to the rail 36 has depressions serving to break the tapered end of cops carried by the clips. For donning, the frame is rotated clockwise from the position of Fig. 2 and lowered to bring the cops to the spindles, the clips being disengaged by a partial anticlockwise station.

Title: Process for the manufacture of hydroxyphenyl-serines
Filed: 1952-05-05
Abstract: Hydroxyphenyl serines are obtained by reacting a benzyloxybenzaldehyde with glycocoll, in the presence of an alkali metal hydroxide and a mixture consisting of methyl or ethyl alcohol and water as solvent, and subsequently splitting off the benzyl radical or radicals.  The benzyl radical(s) may be split off, for example, by catalytic hydrogenation or by hydrolysis with a hydrohalic acid, especially hydrobromic acid.  Suitable benzyl oxybenzaldehydes are, for example, o-, m- or p-benzyloxybenzaldehyde, 3,4-, 2,3-, 2,5-, or 3,5-di-(benzyloxy)-benzaldehyde, 2 - benzyloxy - 5 - chlorobenzaldehyde and tribenzyloxybenzaldehyde.  In the examples: (a) p-benzyloxybenzaldehyde, glycocoll, alcohol, sodium hydroxide and water are heated together to give p-benzyloxyphenylserine which is hydrogenated to give p-hydroxyphenyl-serine; o-hydroxyphenyl-serine is obtained if o-benzyloxybenzaldehyde is used as starting material; (b) 2-benzyloxy-5-chlorobenzaldehyde is reacted with glycocoll in the presence of sodium hydroxide to give 2-benzyloxy-5-chlorophenyl-serine which on treating with hydrobromic acid gives 2-hydroxy-5-chlorophenyl-serine; (c) 3,4-dibenzyloxybenzaldehyde is reacted with glycocoll in the presence of sodium hydroxide to give 3,4-di-(benzyloxy) - phenyl - serine which is hydrogenated to give 3,4-dihydroxy-phenyl-serine, and (d) p-benzyloxybenzaldehyde is reacted with glycocoll in the presence of sodium hydroxide to give p-benzyloxyphenyl-serine which on hydrogenation gives p-hydroxyphenyl-serine; if o-benzyloxybenzaldehyde is used as starting material o - hydroxyphenylserine is obtained.  2 - Benzyloxy - 5 - chlorobenzaldehyde used as starting material in one example is obtained by reacting 2-hydroxy-5-chlorobenzaldehyde with benzyl chloride in the presence of potassium hydroxide.

Title: Error-measurement systems
IPC: H04L25/04
Filed: 1971-04-28
Abstract: 1318824 Data transmission system testing SIEMENS AG 28 April 1971 [29 April 1970] 11780/71 Heading H4P In a testing of a data transmission system where a test pattern of predetermined length is transmitted and compared at the receiver bitby-bit with an identical locally generated test pattern and the total number of errors counted or alternatively the number of bit-blocks containing at least one error counted, the receiver can vary the bit-length of the block on which an assessment is based. In the receiver of Fig. 2 a test pattern received at E is compared bit-by-bit in a comparator V with an identical pattern generated by shiftregister SR having mod-2 addition feedback A1. The two patterns are initially synchronized before measurements are taken by setting the register to a point 20 bit positions before the end of the pattern and then comparing the register output with the received pattern. Any lack of coincidence found by comparator V causes the register to be reset via gate G2 to the 20 bit point. The register on attaining the end of the pattern is deemed to be synchronized and a gate G3 detects the all-zero condition of the register to reset bi-stable K1 via gate G4, so removing the inhibition from gate G1 Any subsequent error pulses from comparator V pass through gates G1, G5 to error counter F2. To measure block-errors, each error signal from the comparator via a now closed switch (not shown) sets bi-stable K2 to close gate G5 so blocking pulses to counter FZ. K2 is only reset at the end of each block by counter Z, so that only one error pulse per block reaches counter FZ. Counter Z is set to the derived block length and is driven by clock pulses T (S1 down) if the block length is less than the test pattern length or by pulses from gate G3 at the end of each test pattern (S1 up) if the block length is greater than the test pattern length. To terminate either measurement switch S2 is put to position 1 and at the end of the next test cycle, for total errors, or at the next coincidence of the end of a test pattern and block length, for block errors, switching unit D operates to set bi-stable K1 via gate G6, so inhibiting gate G1 to further error pulses. The circuit of Fig. 2 may act as a transmitter of the test pattern by putting switch S3 to position 1 and feeding the output of register SR via gate G7 to output A.

Abstract: 595,510. Making magnetic powder. STANDARD TELEPHONES & CABLES, Ltd., and BUCKLEY, S. E. May 14, 1945, No. 12064. [Classes 83 (i) and 83 (ii)] Foundry moulds.-A process for manufacturing finely-divided magnetic material comprises melting magnetic material, adding thereto an embrittling agent and casting the molten material into ingots of such size, shape and construction that the ingots so formed are cooled so rapidly that a fine grained crystalline structure substantially free from long needle-like crystals is produced throughout the greater part of the ingot. A molten nickel-iron alloy containing an embrittling agent is cast into a mould comprising two side plates 1 of mild steel or cast iron about three feet square, pressed by clamps 3 on to a U-shaped spacing piece 2 about “ inch thick. The side plates may be water-cooled. Pouring is facilitated by a refractory tundish 4. After cooling, the cast material is broken into fragments in a hammer mill and the pieces ground to a fine powder. The fragments may be reheated to the temperature of recrystallisation and rapidly quenched in cold water from that temperature before being ground into powder. As a further alternative, the mould may be taken apart as soon as the ingot has cooled to the temperature of recrystallisation and the ingot then quenched in cold water.

The nickel-chromium helix a, Fig. 2, may be coiled on a silica tube b in a groove therein, or the turns may be separated by an asbestos or like strip c on a plain tube. Studs b<1>, b<2> fused into the tube secure the ends of the helix. ' The uncoiled ends of the filament are folded several times and then twisted together about pieces of ccpper wire d, which are coupled by sheet-metal sleeves g to the supply conductors. The outer end of the filament is brought back through the tube. In order to concentrate heat at the end of the tube, a small part of the helix is coiled up within the end of the tube; or the end of the tube is tapered so that the helix may extend over it. The outer silica tube may be closed at one end, and may be fused at the other end to the inner tube; the intermediate space can then be exhausted. An asbestos or other packing-ring i<2> is compressed on to the outer tube by a gland i<1> screwing into a handle j, to which may be attached a guard k. Alternatively, the tubes may be mounted in a cap like that of a glow lamp. In a larger heater, the packing ring is compressed within a short socket by a screw cap, and a handle at right angles to the tubes is attached by arms to the socket. The guard is provided at its outer end with a strengthening-ring and with spring fingers for steadying the outer tube. In an immersion heater for a bath, a float m, Fig. 6, carries a combined guard and stand o and four heating-tubes h, secured by stuffing-boxes m<6> and by spring fingers n<3>.
