Title: Improvements in or relating to straight-bar knitting machines
Inventor: WHEELDON JOHN THOMAS
IPC: D04B15/88
Filed: 1957-12-27
Abstract: 849,531. Knitting-machines. MORLEY Ltd., I. & R. Feb. 13, 1959 [Dec. 27, 1957], No. 40150/57. Class 74 (2). After a rib welt has been transferred to the needles of a straight-bar machine, it is engaged by points or hooks on an endless band or bands in front of each needle-bar and extending from a point adjacent the needles to a point adjacent the take-up roller, and is thereby carried towards and delivered over a take-up roller or between it and an associated roller. In Fig. 1, points 15 are provided on an endless band or bands 1 carried by rollers 3, 4. The roller 4 is belt-driven from the take-up roller 6 and is carried by a bracket 10. The roller 3 is borne on an arm 8 pivoted at 9 to the machine frame and to it is secured, by a spring- clip 18, a guide-plate 16 formed with wings 17 which, as the fabric passes over them, lift it off the points and deliver it over the roller 6. An additional fabric lifting finger may be provided, secured at the front end of the machine, passing over the take-up roller and having its rear end located between the rows of points. The fabric is collected in a container 19. In Fig. 3, the bands are in pairs (of which one band 21 is shown). The fabric-engaging surfaces of the bands are coated with a fabric-gripping granular substance such as carborundum. The fabric is placed on the bands by wheels 27, driven by friction and bearing each a pair of fabricengaging pins 28; and it is removed by a brush 29 rotating with a shaft 30 which drives the larger band rollers 24 through a belt 31. In Fig. 6, hooks 41 on two bands 32, 33, associated with each needle bar and running in guides 34, 35, pivoted on a shaft 40, engage a welt when it is placed on the needles; and the bands are then withdrawn by means of pin-wheels 38, 39 secured to the shaft 40, which is stepped round by pawl-and-ratchet. Fabric take-up rollers 43 on a second shaft, also stepped round by pawl-and-ratchet, engage with rollers 44, loose on shaft 40, to provide pairs of take-up rollers. When the fabric has been delivered between the roller pairs, the pin-wheel ratchet is disabled and the shaft 40 is rotated in the reverse direction to return the hooks 41 to their starting- point. This reverse rotation may be produced by an electric motor or by a weight on a cable wound up by a pulley on the shaft 40 during forward rotation of that shaft. The pawl is controlled by a bluff-plate positioned by a double-acting solenoid, the switches of which are associated with, respectively, automatic welt transfer mechanism and a worm 48 on the pin-wheel shaft 40.

Title: Process for the recovery of polycarbonates from solutions thereof
IPC: C08G64/40
Filed: 1963-10-11
Abstract: <FORM:1039547/C3/1> Solid polycarbonates are recovered from their solutions by introducing a polycarbonate solution into a shearing device having an operating speed sufficient to cut the polycarbonate particles as they are precipitated, while concurrently maintaining in the shearing device a turbulent stream of polycarbonate non-solvent having a Reynolds number of at least 1500 and while maintaining the temperature in the shearing device at at least the boiling point of the polycarbonate solvent.  The shearing device preferably operates at a speed of 2000 to 20,000 r.p.m.  The polycarbonate solvent may be a chlorinated aliphatic hydrocarbon, thiophene, dioxan, tetrahydrofuran, acetophenone, anisole, cyclohexanone, benzonitrile, dimethyl formamide or nitrobenzene.  The non-solvent may be water, a hydrocarbon, acetone, ethyl acetate, trichloroethylene, carbon tetrachloride, 1,1-dichloroethane, nitromethane, acetonitrile or a dialkyl carbonate.  Polycarbonate solution is sprayed into a shearing device 5 also fed with a stream of hot water from a pump 4.  The output from the shearing device flows to a tank 1, the temperature of which is maintained at above the boiling point of the polycarbonate solvent by spurging live steam into it. Volatilized solvent is removed from the top of the tank whilst hot water is removed from the bottom via a screen 2.  Polycarbonate particles collect above the valve 3 and are removed and passed to a dryer.  In place of the valve, a star feed or a de-watering screw conveyer may be used.  In an alternative, the screen 2 may be removed and the solids recirculated via pump 4 with controlled removal of slurry at 7.  In examples, the polycarbonate solution used is one obtained by phosgenating bisphenol A in the presence of methylene chloride.

Abstract: 960,143. Electronic counters. STANDARD TELEPHONES & CABLES Ltd. Nov. 2, 1962 [Nov. 8, 1961], No. 41613/62. Heading G4A. [Also in Division H3] A multistable storage device comprises a series arrangement of a plurality of tunnel diodes DK having different peak currents coupled to the output of a bistable circuit Q1, Q2 and in which successive input pulses each switch the bistable circuit from a first to second condition whereby one of the tunnel diodes is switched to its high resistance state, and in which subsequent to the storage of input pulses, interrogation is initiated by converting the bistable circuit into a monostable circuit, whereby tunnel diodes remaining in the low resistance state during storage of input pulses are switched to the high resistance state. Each input pulse turns transistor Q2 on, charging the state of the bistable circuit, the current rises until a tunnel diode changes state producing a voltage pulse which via capacitor CK turns off transistor Q2. Read out is initiated by converting the bistable circuit to a monostable circuit by opening switch S. The transistor Q2 conducts and as current builds up a tunnel diode which is in the original low resistance state is changed into the high resistance state, the resultant voltage pulse turns off the circuit for a one digit period. The serial digit output obtained from the circuit is the complement of the pulse train stored. To erase all information the switch S1 is opened. The input pulses may be fed to the base of transistor Q2.
