Patent GB-669952-A (GB)
Title: Process for the production of organic acids and the esters thereof
IPC: B01J27/06
Filed: 1949-10-06
Abstract: Monocarboxylic aliphatic acids and esters thereof are produced from monohydric aliphatic alcohols containing one carbon atom less per molecule than the acid formed by reacting the alcohols with carbon monoxide or carbon monoxide-containing gas under pressure and at elevated temperature in the presence of catalysts consisting of at least one silver halide or of silver or at least one silver halide in the presence of at least one other metal halide.  Preferably the other metal halides used are those of the alkalie earth metals or of heavy metals, e.g. potassium iodide and nickel chloride.  Carbon monoxide may be used in a mixture with hydrogen or with small quantities of carbon dioxide.  The reaction may be carried out at such a temperature that the starting materials and the products are in the gaseous phase and in this case the catalyst should be applied to a carrier, e.g. activated charcoal, copper or the like.  Normally certain quantities of ethers and esters are obtained in addition to the acids but the formation of these is inhibited if a carrier having a dehydrating action is used.  The formation of ethers and esters may also be reduced by isolating them as they are formed and returning them to the cycle.  Preferably a temperature above 250 DEG  C. and a pressure over 100 atm. is used.  Water may be present in the reaction mixture.  In the examples acetic acid and methyl acetate are obtained from methyl alcohol and carbon monoxide with (a) silver iodide; (b) silver bromide; (c) potassium iodide, silver chloride and silver iodide; (d) potassium iodide, nickel chloride and metallic silver, as catalysts.

Abstract: 1487724 Keyboards with coded outputs; telegraphy SIEMENS AG 24 June 1976 [25 Sept 1975] 26228/76 Heading H4P [Also in Division G4] An arrangement for coding data characters comprises a counter TUZ arranged to count cyclically pulses of a pulse train G, a keyboard matric TMF comprising a plurality of intersection points, each associated with a respective data character key and a respective associated count of counter TUZ, for producing in response to actuation of each key one transfer pulse at a time when the counter has the count associated with that key, a gating circuit T1 arranged to transfer the count (e.g. to a store PS) in response to a transfer pulse supplied thereto, means UVFG for supplying the transfer pulse to T1 in the absence of an inhibiting signal, means SDC, T2, OVMZ for detecting a count associated with a hybrid data character key (e.g. õ, ÷, ³, shift) for the coding of which a plurality of consecutive coded characters are required and for producing the inhibiting signal in the presence of a transfer pulse, and means SZ, ASP, FWSP responsive to the production of both a transfer pulse and an inhibiting signal to produce and to supply to T1 a plurality of consecutive transfer pulses at times at which the counts of TUZ are those associated with keys relating to consecutive data characters (e.g. a, e) corresponding to the hybrid data character (e.g. õ) selected. As shown, SDC detects a hybrid count to produce a signal on one of four leads which passes through a gate T2 enabled by the transfer pulse to a gate OVHZ and an addressing store ASP (Fig. 3, not shown). The output of OVMZ provides the inhibiting pulse for a gate UVFG, and also enables a counter SZ which counts pulses G in synchronism with TUZ. The outputs of ASP and SZ address a read-only store FWSP (Fig. 3) which produces one output from each of a pair of selected NOR gates therein at counts in SZ corresponding to the required two characters making up the hybrid. These outputs pass via gate OVFG to enable gate T1 for the corresponding counts in TUZ. A counter ZZ, a gate NOR32 and an analyser TB are provided to eliminate "bounce effects". Circuit SDC may be neutralized by an input A (e.g. from a keyboard key so that no hybrid characters, or only certain ones, are detected.

Class 142(iii) Upon weft breakage, a combined shuttle feeler and weft cutter is moved horizontally and enters an opening in the shuttle box wall and a corresponding opening in the shuttle to check the position of the shuttle and to cut and grip the weft. If the shuttle is correctly positioned, the bobbin transfer hammer is operated by an abutment on the slay engaging a pawl 19. When weft failure occurs, a shaft 29 is turned in the direction of the arrow A and by means of a toothed segment 30, a gear 31, an arm 32 and a connecting rod 33, a support 12 for the shuttle feeler 20 and the cutting and gripping jaws is moved horizontally towards the shuttle box. The pawl 19, when engaged by the slay abutment, pivots to engage a lever 16, pivoted at 15, whose end 18 moves a lever 26 to operate the cutters and gripping jaws located in a slot 21 in the feeler. On further pivoting, the pawl 19 engages a recess 14 and a member 8 is pivoted and operates the hammer 10. The cut weft end is withdrawn from the shuttle eye as the slay moves back. The support 12 returns to the inoperative position when the shaft 29 returns to its initial position. An eccentrically mounted support 34 provides adjustment of the horizontal position of the feeler and cutting and gripping jaws. Specification 405,179 is referred to.

Title: Improvements in or relating to methods of producing silicon of high purity
Inventor: WILSON JACK MCCREATH
IPC: C01B33/04
Filed: 1953-09-25
Abstract: <PICT:0745698/III/1> Pure silicon is prepared by the thermal decomposition of silane (SiH4) by heating to temperatures between the decomposition temperature (about 500 DEG C.) and 800 DEG C. and with molecular concentrations about 0.3 per cent.  The silane may be decomposed so as to form a coherent body around a seed of pure silicon.  In Fig. 2 pure silane, preheated by heater 28, is drawn through aperture 27 via valve 25 and flow meter 24 into decomposition chamber 12 by a vacuum pump connected to outlet 29.  The gas flow is directed on to the silicon seed 16 supported on rod 17 and heated by copper current concentrator 18, itself cooled by water in coil 19, and primary coil 22 which form the tuned circuit of an induction heater (see Group XI).  The rod 17 passes through a vacuum seal 31 and is connected to a mechanism 32 which alters its position so as to give optimum crystal growth.  Pure silane is prepared from silicon tetrachloride and lithium aluminium hydride. Silicon tetrachloride is refluxed with copper turnings and the arsenic content reduced to less than 0.01 micrograms per mililitre by fractional distillation of the chloride.  The silicon tetrachloride is then mixed with pure dry ether or tetrahydrofuran, and reacted with lithium aluminium hydride which has also been refluxed with pure dry ether or tetrahydrofuran. The resulting silane after fractional freezing and distillation may be stored in cylinders or swept straight into the decomposition chamber with an inert gas.

Title: Improvements in or relating to indicating or repeating devices linked or associated wth inaccessible transmitters
IPC: G01C17/36
Filed: 1931-09-23
Abstract: 382,999. Electric signalling systems. BAULE, M. E. A., 13, Rue Leon Gambetta, Chaville, Seine-et-Oise, France. Sept. 23, 1931, No. 26581. [Class 40 (i).] An inaccessible rotatable member. fitted with a bar magnet, controls the movement of a magnetic needle which is followed by a hunting transmitter to communicate the movement of the inaccessible member to a remote point. As shown in Figs. 1 and 2 the inacc essible member 2 carries a bar magnet 8 which controls the small magnetized needle 6. As 6 follows the movement of 2 it makes contact with one or other of contact pins 9, 91, completing a circuit for motor 14 to drive the plate 11 until 6 is again central between 9 and 9<1>, the device 17. coupled directly to 14, sending a suitable signal to the remote point to indicate the movement made. As shown in Fig. 3, the small magnetized needle 25 which follows the movement of the prime mover, is periodically lifted, by means of the pneumatic device 42, 44, so that contact wheels 26, 27 make contact with rings 28, 29 to close a circuit for a motor (not shown). The motor, by means of gearing 33, 34, drives the member 30 until the wheel 26 contacts with an insulated portion of ring 28, a signal transmitter, coupled to the motor, sending a suitable signal to the remote point to indicate the movement made by 30 which is equivalent to the movement of the inaccessible member. The pneumatic device 42, 44 may be operated by the solenoid 48, 49, Fig. 6, the switch 50 being closed either by hand or by automatic means. A system is also described in which the readings transmitted differ by a predetermined fixed amount from the actual movement of the needle 25, the adjustment being effected by providing an adjustable coupling between 30 and 33.
