Patent GB-306464-A (GB)
Title: Process for producing solutions adapted to be spun
IPC: D01F4/00
Filed: 1929-02-20
Abstract: 306,464. Heberlein & Co. Akt.-Ges. Feb. 20, 1928, [Convention date]. Albumens, - Solutions of animal proteins. of sparing solubility and high molecular weight, are prepared by subjecting the proteins to a swelling operation and to a simultaneous or subsequent treatment with phenol, or homologues or derivatives thereof or with a mixture of these, until .solution occurs. The swelling operation may be effected with hot water, if necessary under pressure, and the effect may be increased by the addition of acid in quantity such that no degradation of the protein occurs. The swollen mass is then dissolved in the phenolic substances in the liquid state to form viscous liquids, but if the protein swells sufficiently in the phenolic substances the preliminary swelling may be omitted. The dissolving of the protein can be assisted by heating, but decomposition of the protein must be avoided. The phenolic substances should have low melting points below 100 C. In some cases the addition of a small proportion of water is desirable to improve the fluidity. Horn, skin, flesh, waste wool, and waste silk are suitable proteins. In one example, horn shavings are heated with hot water and salicylic acid until they become soft and swollen, and after draining are introduced into about 10 times their weight of liquid phenol. The temperature should not exceed the boiling point of water in order to avoid hydrolysis. The swelling operation can be repeated several times by further addition of water. When they are completely dissolved, the added water may be separated by evaporation, but not beyond the point at which there is still enough water to retain the whole of the phenol in liquid condition. In another example, waste skin is gently warmed under a reflux condenser with about 5 times its own weight of crystallized phenol, if the waste skin has its natural-water content, or with phenol liquefied by water, if the waste skin is dry, and sulphur dioxide is introduced. The skin dissolves easily with strong swelling.

Abstract: 930,120. Automatic control of flight. JOS. SCHABERGER & CO. G.m.b.H. Feb. 18, 1960, No. 5877/60. Class 38 (4). [Also in Group XIX] Apparatus for detecting lateral accelerations of a highspeed flying body and which may act to control rudders to restore the body to its intended flight path comprises, Fig. 1, a chamber 3 maintained filled to a constant level with an electrically conducting liquid supplied through an opening 12 from a container 1. A membrane 4 retains the liquid until the apparatus is to be used. In use, the liquid issues in a jet from a nozzle 13 and, in the absence of lateral accelerations, a knife-edge 7 divides the jet into two equal parts which enter chambers 8. Each chamber 8 contains a pair of electrodes 9, the resistance between each pair decreasing upon increase of the depth of liquid. The electrodes 9 may be connected in a bridge circuit which is balanced when there are equal amounts of liquid in the chambers and hence a lateral acceleration which causes these amounts to be unequal will unbalance the bridge and a restoring action is applied to the flying body until the two liquid amounts are equalised. In a modified apparatus, Fig. 2, the liquid flowing through the nozzle 13 enters a pipe 17 and, in the absence of lateral accelerations, leaves in equal amounts from nozzles provided at the pipe ends, the liquid entering tubes 15 each containing a resistance wire 16 connected to a bridge circuit.

[Also in Division F2] A fluid-pressure system for actuating two servomotors 150, 153 comprises a pressure regulator valve 39 which provides a progressively increasing pressure to the servo 150 until a predetermined pressure is attained whereafter it supplies pressure fluid to the other servo 153. With control valves 64, 152 positioned as shown a pump P supplies pressure fluid through a filter 31 to the servo 150 at a minimum pressure determined by the regulator valve 39, which pressure is insufficient to actuate the servo. A pressure regulator piston 41 of the valve 39 is separated by a spring 107 from a larger piston 102 and the assembly is urged right by a spring 43 which determines the minimum pressure. Operation of the valves 152, 64 closes the line 154 and connects lines 60, 83 to supply pressure fluid to the piston 102 which moves right against the bias of springs 107, 108 and loads the piston 41 to progressively increase the system pressure applied to the servo 150. When a predetermined pressure is attained the piston 102 opens a port 99 and supplies pressure fluid to the other servo 153. When the pressure in the servo 153 attains the predetermined value the piston 102 moves further right to increase system pressure to a maximum determined by a flange 104 abutting a stop 163. On return of the valves 64, 152 to the position shown the servo 153 is vented and the piston 102 moves left to reduce the loading on the relief valve piston 41 whereupon the pressure applied to the servo 150 falls to the minimum value.

Abstract: 1502952 Error syndrome generation COMPAGNIE INTERNATIONALE POUR L'INFORMATIQUE 14 Feb 1975 [19 Feb 1974] 6335/75 Heading G4A An error syndrome generator includes two stages each of a plurality of modulo-two adders, the adders A-V of the first stage receiving selected subcombinations of the bits 1-63 of a multi-byte data word and associated byte parity check bits 64-71, some of the adders J-R generating fresh byte parity check bits, the adders S0-S7 of the second stage receiving selected subcombinations of the output bits from the adders of the first stage, and some of the adders of the second stage also receiving one or more bits of data word, the adders of the second stage generating the bits of the syndrome S0-S7. The subcombinations of bits used are dependent on the matrix of the code used to form the syndrome. As shown, Fig. 7, some of the adders of the second stage receive a bit from the data word which cancels the same bit which is present in the subcombination supplied by one of the adder of the first stage supplying the second stage adder, e.g. adder S1 receives bits 24, 25 which are present in the subcombination M also supplied to adder S1. Similarly the same bit may be present in two subcombinations formed by two adders of the first stage which supply the same second stage adder, e.g. bits 0-3 from adder J and from adders D (for bits 0 and 2) and A (for bits 1 and 3) are supplied to adder S3 and thus cancel. The arrangement may be used to correct a word having 8, 8-bit bytes, bits 00-63, and 8 byte check bits 64-71 supplied from a source MEM, e.g. a memory. The syndrome generator CS, as above, generates fresh byte parity check bits (J-R above) P0-P7 which are used in the formation of the syndrome bits S0-S7 as described above. The syndrome produces correction bits 00-63 for any of the data bits shown to be error, the correction bits may for example being exclusive-ORed with the data bits. The syndrome bits S0-S7 are also used to correct the fresh parity check bits in accordance with the correction applied to the data bits. The 64-bit output word and the byte parity check bits are multiplexed to an output on two 32-bit words with associated parity bits.
