Title: Improvements relating to Textile Machines
Inventor: MACKIE JOHN KAY PRINGLE
IPC: D01G15/48
Filed: 1966-04-29
Abstract: 1,170,738. Carding engines. JAMES MACKIE & SONS Ltd. 24 April, 1967 [29 April, 1966], No. 19029/66. Heading D1N. In an arrangement for maintaining oscillations of a stripping knife 2 for a textile machine, the knife is supported by a tubular shaft 1 containing a torsion bar 9, and a driving mechanism produces mechanical impacts acting at intervals on surfaces 21 of arms 20 connected to, and extending radially from, the shaft. The mechanical impacts may be produced by pulses of compressed air applied to a flexible diaphragm 22. The shaft preferably has two laterally extending arms which each include a diaphragm supplied with compressed air from a single rotary valve member 28. The magnitudes of the impacts are controlled by a pneumatic control circuit 40 in dependence of the amplitude of oscillation in order to maintain the amplitude substantially constant. The control circuit 40 includes a pressure regulator 41 in which a throttling valve 47 is acted on by subsidiary air pressure in chamber 64 acting on a diaphragm 65 which in conjunction with a spring 48 tends to open the valve to increase the pressure of the main compressed air supply through conduits 42 and 43 to. the valve member 28. The subsidiary air pressure is adjusted by an interrupted air flow signal device 53, 54 controlled by an interrupter 52 oscillating with the shaft. The greater the amplitude of the oscillation the less long is the air flow interrupted and the greater is the subsidiary pressure, and vice versa. Alternatively the mechanical impacts may be produced by (a) bursts of compressed air directed directly onto the arm, in which case the arm can take the form of a vane operating in a closed housing or (b) a striker in the form of an electrically or mechanically operated cam.

Title: Improvements in or relating to feed devices for veneer cutting machines, lathes, milling machines and the like
IPC: B23Q5/40
Filed: 1922-07-13
Abstract: 183,138. Aktiebalaget G. Ahrens Mekaniska Verkstad. July 13, 1921, [Convention date]. Lathes; milling.-A feed device for a lathe, milling or like machine has continuously rotating nuts, and spindles mounted therein, the latter being held stationary for feeding the cutter, rotated in either direction for advancing or withdrawing the cutter, or being unconstrained when no motion is required. The nuts 19, 20 are continuously driven through a friction clutch 9, gearing 11, 12, and worms 13. The spindles 21, 22, having right and left hand threads respectively, are axially constrained in bearings 23 mounted on the cutter-slide 24 and carry bevel wheels 26, 27 gearing with wheels 28, 29 secured to a shaft 32, which is rotated in either direction by means of a hand-wheel 33, or by a clutch 34, 52, gearing 38 39, shaft 40, gearing 42, 44, shaft 45, and friction gearing 46 and 48 or 49. In operation, the work is mounted between centres 2, 3, and the slide is given a slow cutting-feed by engaging the clutch 34 with a stationary clutch 37, these being so designed as to remain in engagement, and the friction gears 46, 49 being kept in contact by a spring 50. At the end of the cutting stroke, the surface 60 of an arm 57, pivoted to the slide, strikes a fixed stop 61 and releases the clutch, owing to the surface 59 coacting, against the action of a spring (not shown), with a pin 58 on the lever 36. A spring 53 then engages the clutches 34 and 52, whereby the slide is rapidly withdrawn. At the end of the backward stroke, a pin 62 on the slide strikes a lever 51 which disengages the friction drive and thus stops the slide. The latter is brought rapidly up to a new piece of work by engaging the friction gears 46 and 48. The arm 57 may be actuated by hand, and carries a stop 55 for holding the clutch-lever in neutral position, as shown in Fig. 2. The lever 51 may also be operated by hand. The clutch 9 is kept in engagement by a spring 17 and may be released by a hand-lever 16. In a modification, the gear wheels 26, 27 form the nuts, the spindles then being fixed to worm-wheels 19, 20 and forming the continuously rotating members.

Title: A process for the manufacture of ammonium salts
IPC: C01C1/242
Filed: 1932-07-08
Abstract: <PICT:0390980/III/1> In the production of ammonium salts, e.g. the sulphate or phosphates, aqueous or gaseous ammonia and an acid are continuously introduced into a container, the temperature of the container is controlled by means of a vacuum applied throughout the reaction, the ammonium salt formed is continuously withdrawn and the mother liquor is separated from the crystals of ammonium salt being returned wholly or in part to the container.  A saturator or bath 1 is maintained under vacuum by a pump 2. Ammonia is fed through a pipe 4 and perforated distributer ring 8 while sulphuric acid is added through a pipe 6.  A stirrer 9 is provided.  The heat of reaction causes an evaporation of water at a temperature depending on the vacuum, the water evolved passing through a pipe 3 to a condenser 18. The condensate may be wholly or in part returned to the saturator through pipes 25, 26. Additional water may be supplied through a pipe 19.  The ammonium sulphate crystals are pumped by a pump 13 through a pipe 12 into a settler 14.  The larger crystals are removed through a pipe 15 to a centrifuging or filtering apparatus, the mother liquor removed in this apparatus returning via a pipe 16 to a trough 22 surrounding the top of the settler.  Agitation in the settler causes the smaller crystals to flow into the trough 22 whence they are returned to the saturator through a pipe 17.  An open tank 23 provided with a heating coil 24 may be interposed in the line 17 for use when aqueous ammonia or dilute sulphuric acid are employed, the necessary additional heat for evaporation being thereby supplied to the saturator.  Vacuums of only a few centimetres of mercury below atmospheric pressure may be employed but preferably a higher vacuum, e.g. a total pressure of not more than 10 cms. of mercury, is employed.

Title: Polyamide preparation process
Inventor: CLEMO PHILIP FRANCIS
IPC: C08G69/28
Filed: 1959-06-06
Abstract: A process for the manufacture of high molecular weight polyamides from polymethylene diammonium salts of aliphatic alpha, omega dicarboxylic acids, said salts containing from 8 to 24 carbon atoms comprises passing a hot aqueous solution of the salt containing from 45 to 70% by weight thereof through a pressure tube at polyamide-forming temperatures under a pressure at least sufficient to prevent the evolution of steam and for a time such that a degree of polymerization of from 1,15 to 1,37 is attained, suddenly reducing the pressure to atmospheric pressure by passing the resultant propolymer solution through a jet or valve into a chamber at substantially atmospheric pressure so that the ensuing expansion is approximately adiabatic and heating in order to complete the polymerization in said chamber and/or one or more further vessels, at atmospheric or higher pressures, the water of reaction being removed in the form of steam.  Specified diammonium salts are hexamethylene diammonium adipate, hexamethylene diammonium sebacate, octamethylene diammonium adipate, decamethylene diammonium adipate, pentamethylene diammonium sebacate and dodecamethylene diammonium adipate.  The examples describe an apparatus and exemplify the condensation of hexamethylene diammonium adipate, in one example on the presence of acetic acid.

Title: Improvements relating to electro-pneumatic braking apparatus
IPC: B60T13/68
Filed: 1921-07-19
Abstract: 177,127. Westinghouse Brake & Saxby Signal Co., Ltd., (Assignees of Thomas, T. H.). March 17, 1921, [Convention date]. Fluid-pressure.-In electropneumatic braking apparatus the de-energization of the valve magnets is arranged to be temporarily delayed when the control switch is moved to positions for deenergizing the magnets to compensate for the relatively slower energization of another or other valve magnets, the circuits of which are closed in the same positions of the switch. In the system shown the valves magnets A, B are respectively de-energized and energized in the running condition (position II of the driver's switch) energized and de-energized in service applications (position V of the switch), and both de-energized in emergency applications. The various connections are effected by the drum contact 25 of the driver's switch which is moved with the handle 4 of the driver's valve and cooperates with stationary contacts 15, 16, 17 connected respectively to the train-wires 26, 27 of the valve magnets A, B and the source of current 19. In addition there is provided a switch bar 11 which in the running position of the driver's valve is held in the position shown by compressed air supplied to the piston chamber 6 so that the bar connects the train-wire 27 to the source of current 19 by the contacts 12, 13, 18 in addition to the connection by the contact 16. When the driver's switch is moved to position V for a service application of the brakes, the piston chamber 6 is connected to an exhaust port in the driver's valve, the train-wire 26 is immediately connected to the source of current 19 to energize the valve magnet A and the contact of the wire 27 is disconnected from the source of current, but the wire 27 is maintained energized through the switch bar 11 for an interval required for the escape of the compressed air from the chamber 6. The bar 27 is then moved by the spring 5 to the position in which it disconnects the contacts 12, 13 and connects the contacts 12, 14, so that the train-wire 26 is now connected to the source of current 19 by the switch bar 11 as well as bv the contact 15. Thus when the driver's valve and switch are returned to the running position, the de-energization of the valve magnet A is delayed in a similar manner to that of the magnet B in making a service application of the brakes. The simultaneous de-energization of the magnets A, B and consequent emergency application of the brakes when the switch is moved from running to service application positions and vice versa is thus provided. A timing reservoir may be connected to the pipe 22, or the vent port may be restricted, to provide the necessary delay in the release of the compressed air from the chamber 6.
