Title: Improved process and apparatus for spinning cuprammonium silk by the stretch-spinning process
IPC: D01D5/14
Filed: 1930-08-28
Abstract: 356,457. Artificial silk. BRITISH BEMBERG, Ltd., Hazel House, Milk Street, London. Aug. 28, 1930, No. 25747. Convention date, Aug. 29, 1929. [Class 2 (ii).] In the stretchspinning of cuprammonium silk the thread is guided downwards in a rectilinear path and the jet of precipitating liquid is deviated from the path of the thread before or at the outlet of the spinning apparatus but before the collecting or guiding member. In this manner the thread arrives on or in the further devices of the spinning apparatus with the liquid adherent to its surface only. As shown in Fig. 1, a known cylindrical spinning apparatus 1 has an exit pipe 2 surrounded by tube 3. The tube 3 is connected to pipe 2 by a seal 5, and has a siphon tube 4. The quantity of liquid drawn off by the siphon may be adjusted by a tap 6. The thread issuing from the spinning cell with only superficially adhering liquid is guided directly over two rods 13 in a hardening bath 12 underneath the spinning apparatus. The thread issuing from the spinning apparatus may alternatively be passed vertically downwards to a roller round which it passes and upon which it is sprayed with acid. It is passed horizontally from the first roller to a second roller after which it is collected in a centrifuge. As shown in Fig. 3, the siphon tube is dispensed with and the tube 3 is provided with a small rod or sheet-metal member 10 which diverts the current of liquid issuing from the apparatus away from the path of the thread. As shown in Fig. 6, the tube 3 has a siphon tube 4 the lower end of which projects below the orifice of tube 3 and carries an overflow vessel 16. The vessel 16 is slidably mounted on the tube 4 by means of a resilient sleeve 17. The rate of flow of liquid through the tube 4 may be regulated by adjusting the position of the vessel 16 on the tube 4. The thread issuing from the tube 3 may be passed vertically downwards to a driven roller, then vertically upwards to another roller displaced with respect to the first, and then led to a centrifuge, reel, or bobbin. For economy of space, the spinning apparatus, guiding and withdrawal rollers, and the receiving apparatus for the thread may be arranged vertically underneath one another.

Filed: 1973-05-30
Abstract: 1378737 Rolling mills ZDARSKE STROJIRNY A SLEVARNY NARODNI PODNIK 30 May 1972 [30 May 1973] 25763/73 Heading B3M The vertical rolls 1 of a universal rolling mill are supported in chocks 2 which are horizontally slidable on guide bars 3 attached to the mill frame 4. The chocks are adjustable by rods 5 having oppositely threaded ends which cooperate with pivotable nuts 6 in the chocks. The rods pass through the frame 4 without transferring the rolling loads to the frame. Each rod has a rotatable bush 7 near one end, and a threaded bush 8 near the opposite end. Rotation of the bushes 7, which are keyed to the rods, causes the oppositely threaded ends to move the chocks towards or away from each other. Rotation of the bushes 8, however, causes axial movement of the rods to shift the two chocks laterally relative to the pass line. Backlash in the nuts 6 is taken up by balancing units 10.

Title: Improved process for the production of liquid fuel suitable for internal combustion engines
IPC: C10L1/02
Filed: 1923-10-17
Abstract: 232,276. Distillers Co., Ltd., and Hutchinson, H. B. Oct. 17, 1923. Motor spirit consisting of a stable mixture of alcohol and petrol or other hydrocarbon oil is obtained by distilling the mixture until the greater portion of the contained water has passed over, allowing the distillate to stand, and mixing the layer consisting mainly of alcohol and hydrocarbon with the mixture of alcohol and hydrocarbon remaining in the still. In an example. a mixture of equal volumes of low-grade netrol and alcohol of 95 per cent strength is heated in a still, and the vapours passed through a fractionating column 2 into a separator 4 maintained at 58-65‹ C. Any condensate is returned to the column 2 by a pipe 6. Uncondensed vapours are led to a condenser 5 from which the liquid is run into a separating vessel 8. The lower layer of water with some alcohol is run into a vessel 12 and sprayed with water or brine to separate any contained hydrocarbon, the aqueous alcohol is run off to a separate still and concentrated, and the hydrocarbon is run .through pipes 15, 16 to a container 17 in which it is mixed with the alcohol-hydrocarbon laver from the vessel 8, and with the cooled residue from the still 1. At the commencement' of the distillation the temperature in the separator 4 and in the exit pipe 3 may be kept at 45‹ and 55-58‹ C. respectively, to admit of the lower boiling constituents of the petrol being partially separated and run direct to the container 17.

Title: Improvements in or relating to thermionic valve counter circuits
IPC: H03K23/82
Filed: 1944-12-30
Abstract: 584,422. Pulse counting circuits. TAYLOR, S. M. Dec. 30, 1944, No. 26192. [Class 40 (v)] [Also in Group XIX] In a counter circuit for producing an output pulse for every 2n + 1 input pulses, an electronic switch passes the input pulses to a series of n scale-of-two units forming a scale of 2n chain, an output pulse from the chain operating the switch to connect the input circuit to the output circuit to produce a pulse coincident with the 2n + 1 input pulse, the output circuit restoring the switch to the normal position. A further scale of two unit may precede or follow the circuit giving a 2(2n+1) counter, or scale of ten, when n=2. The scale of two units, Fig. 1, comprises a trigger circuit or multivibrator biassed to have two stable states with either valve 1 or valve 2 conducting, the other being cut off. A negative pulse, applied to the grids of both valves, reverses their state, the positive pulse appearing in the anode circuit of vavle 2 when it is cut-off, by alternate negative pulses, causing normally non-conducting valve 3 to pass current and generate a negative pulse on its anode. The scale-of-ten counter, Fig. 2, comprises a scale-of-two unit consisting of double triode valve 10 feeding pentodes 12, 13 which act in a similar manner to valve 3, the valve 13 normally being cut off at the suppressor grid. Negative pulses from valve 12 feed scale-of-two units 14, 15 the output from which reverses the state of trigger valve 16 which cuts off valve 12 and allows valve 13 to conduct. The next pulse from valve 10 passes through valve 13 to restore the trigger device 16 and generate an output pulse through triode 17. When valve 16 is restored the rise in suppressor grid potential of valve 12 is delayed due to the condenser 18 to avoid passing an extra pulse to units 14, 15.
