Abstract: 956,853. Weft replenishing mechanisms; weft end manipulating. RUTI MACHINERY WORKS Ltd. April 6,1961 [April 11,1960], No.12482/61. Heading D1E. A weft end stripping mechanism comprises a reciprocable suction tube 3, with a flexible stripper 4, and a brake 23 which, when the stripper is moved to the bobbin 15, pivoted by a cam 26 to allow the stripper to grip the tip bunch 21 and, on withdrawal of the stripper, acts to grip the weft against the stripper during the first pick and is then slightly pivoted by a member 29 to allow the cut weft to be drawn into the stripper. Upon response to a weft feeler scissors 30 are advanced, to the position shown in Fig. 1 which, via levers 50, 48, 81, 77, and 74 causes a pin 67 to project. As the slay 40 advances a track 69 acts on the pin 67 to pivot a lever 65 which causes, via levers 64, 62, 56 and 12, the stripper 3 to advance and retract. Further advancement of the slay 40 operates the bobbin hammer 19 and retracts the scissors 30 causing a cam 54 to operate the scissors to cut the weft. As the scissors retract the pin 67 is withdrawn from the track 69 so that return of the slay does not again reciprocate the stripper.

Title: Purification of terephthalic acid
Inventor: FUCHS OTTO
IPC: C07C51/42
Filed: 1956-04-27
Abstract: Mixtures of terephthalic acid with one or more toluic acids are separated by suspending the mixture of acids in a liquid medium consisting of one or more alcohols containing at the most 6 carbon atoms and at most 3 hydroxyl groups or a mixture of such alcohols with not more than the same weight of an aliphatic ketone, an aromatic hydrocarbon, an araliphatic alcohol or a mixture of 2 or more of these compounds, the said medium being liquid under reaction conditions and inert towards the reactants, saturating the suspension at a temperature not exceeding about 130 DEG  C., with ammonia and separating the liquid from the undissolved ammonium terephthalate. The ammonium terephthalate is dissolved in water and the resulting solution acidified with, e.g. hydrogen chloride gas when the pure terephthalic acid is precipitated.  Detailed examples are given using methanol, a mixture of methanol and acetone, a mixture of methanol and benzene, and a mixture of ethylene glycol and methyl ethyl ketone as the reaction medium. Other suitable specified liquid media are, for example, ethyl alcohol, isobutyl alcohol, secondary and tertiary butanol, hexanols, propane diols, glycerine, alone or together with, e.g., diisopropyl ketone, toluene, chlorobenzene, and methyl benzyl alcohol.
Patent GB-1462690-A (GB)
Title: Computer comprising three data processors
IPC: G06F1/12
Filed: 1974-03-25
Abstract: 1462690 Data processing system HASLER AG 25 March 1974 [28 March 1973] 13138/74 Heading G4A The system employs three processors which operate simultaneously on identical instructions. Execution of an instruction is initiated in each of the processors by the output of a majority gate which occurs when at least two of the processors have completed the execution of the previous instruction. Access to a common memory is via a majority circuit and the processors are synchronized with each memory access. If one processor fails it is taken out of service and an identification signal generated. Each processor 1 (1U, 1V, 1W), Fig. 3, includes its own clock 6 which feeds a control unit 7 which accesses a memory common to the processors and which controls an instruction execution unit 8. At the end of execution of an instruction by a processor the associated control unit 7 passes an EOI signal to a majority gate 9 in each processor. The EOI signals are delayed (10) as necessary to take account of the differing execution speeds of the processors. The majority circuits simultaneously initiate the next instruction by an SNI signal when two or more EOI signals are received. Access from the processors to the memory 2 is via a single majority circuit 21, Fig. 4. When a control unit 7 sends an access pulse towards the memory via line 13 an associated bi-stable 11 is reset, so that gate 12 no longer passes signals from the clock 6 to the control unit. The memory is accessed only if the majority circuit 21 receives access pulses on lines 13 from at least two of the processors. The response from the memory passes to each processor and causes the bi-stables 11 to be set simultaneously so that the control units again receive clock pulses. The majority circuit 21 also provides an error signal to the processors indicating which of the processors is providing a signal differing from those of the other two. If the error signals pertinent to a particular processor exceed a certain rate it is first assumed that the contents of a register in the processor are incorrect. A correction program is then initiated, employing the majority circuit, to bring the contents of the corresponding registers in each processor to the same values. If errors still persist and two of the processors indicate that the third is faulty that processor is rendered inactive, for example by inhibiting two or more of the gates 19 so that there is no more than one EOI signal at the input to the majority gate 9.

IPC: C07C45/54
Abstract: 131,399. Soc. Chimique des Usines du Rh¶ne anciennement Gilliard, P. Monnet et Cartier. June 22, 1917, [Convention date]. Acetaldehyde; acetic anhydride.-Ethylidene diacetate is decomposed into acetaldehyde and acetic anhydride by heating it at atmospheric pressure with catalysts (acids or acid salts) below its boiling-point; if the temperature is kept below the boiling-point of the acetic anhydride, the acetaldehyde can be distilled off separately. The removal of the acetaldehyde may be assisted by passing air through the reaction mixture. The ethylidene diacetate may be employed mixed with a diluent such as acetic acid or anhydride; the catalyst may be employed dissolved in a neutral solvent such as hydrocarbons or ketones of high boiling-point. Suitable catalysts are sodium pyrosulphate, monosodium orthophosphate, metaboric acid, and sulphacetic acid. Specifications 23190/14 and 110,906 are referred to.

Abstract: 902,460. Turbine power plant. POWER JETS (RESEARCH & DEVELOPMENT) Ltd. April 6, 1960 [April 17, 1959], No. 13141/59. Class 110 (3). [Also in Group XXXI] A turbine power plant comprising two turbines, each of which has an inlet control valve to regulate the flow of working fluid and an output shaft connected to different elements of a differential gear, has the third element of the differential gear connected to the output shaft and a unidirectional clutch connecting one of the turbines to the output shaft when that turbine is driven in reverse by the other turbine. Two free piston gas generators 1, 2, having blow-off valves 3, 4, operated under idling conditions, supply working fluid to turbines 7, 8 through control valves 9, 10. The turbine 7 is connected through shaft 11, pinion 12, gear 13 and shaft 14 to the bevel gear 15 forming part of a differential gear. The output shaft 16 of the turbine 8 is connected through pinion 17, gear 18 and shaft 19 to the second element 20 of the differential gear. The other end of the shaft 16 is connected, when the turbine 8 is driven in the reverse direction, through a unidirectional clutch 21, gears 24, 24A, 25, 27, 28 to the output shaft 29. The shaft 29 is also connected through gears 30, 31 with the bevel wheel carrier 32 of the differential gear. Starting from rest the turbine 7 only is operated and drives the output shaft 29 through the differential gear and the unidirectional clutch 21 and gears 24, 25, 27, 28. Under these conditions, the turbine 8 is driven in the reverse direction. At about 15 m.p.h. turbine 8 is brought into operation. The effective gear ratio between the shaft 14 and output pinion 31 then changes gradually to 1 : 1 when both the turbines are running at the same speed. The differential gear may be, of the epicyclic or other types. A reversing gear train may be placed between the output shaft 29 and the driving wheels.

The shaft 15 can also be clutched at 20 to a bevel pinion 19 driving a vertical screw which raises and lowers the front end of the implement. The shaft 15 slides axially to cause one or other of the clutches 18, 20 to be engaged and is locked in either clutching position by means of radially-sliding blocks 31 which can be caused to engage grooves 23, 24 formed in the shaft. These, blocks are made to slide in and out by partially rotating a cap 25, whereupon pins fixed to the blocks are acted upon by cam grooves and move the blocks into engaging or disengaging position. Automatic power control.-If the implement encountered an abnormal construction a pin on the drawbar member is sheared and allows a collar on the drawbar to move and de-clutch the engine.
