Abstract: <PICT:0471005/IV/1> In a method of dyeing rayon cakes, a plurality of cakes 16, each wrapped in a pervious fabric 17, are assembled in end-to-end contact on a perforate cylindrical member 15 having a cake supporting flange 18 at one end.  The cylinder 15 carrying the cakes is then inserted into a second cylindrical member 20 having an imperforate end, the open ends of the cylinders are closed by a cover 21, and the enclosed cakes are supported in a bath of dyeing liquor with the common axis of the cylinders horizontal.  The dye is passed under pressure through the cakes between their inner and outer peripheries.  The central portion of the cover 21 is depressed as at 22 and is provided with a fastening device in the form of a lock strap 23 which co-operates with a pair of inwardly disposed ledges 25 forming part of a helix on the interior surface of the inner cylinder 15.  The cylinders enclosing the cakes are supported on horizontal, hollow, perforated spindles 14 mounted on the outside of a cylinder 12 suspended with its axis vertical in a tank 30 of dyeing liquid. The spindle 14 passes through holes in the imperforate bottom of the outer cylindrical member 20 and in the cover 21 and the perforated cylinders are held in position by a screw cap 13.  A square boss 26 on the bottom of the outer cylinder cooperates with a square hole in the flange 18 to prevent relative rotation of the inner and outer cylinders.  The dyeing liquor may be circulated either inwards or outwards through the cakes.

Title: Improvements relating to electric motor control systems
Inventor: WILSON GRAHAM RUDGE
IPC: H02P7/34
Filed: 1953-06-23
Abstract: 740,402. Automatic speed-control systems. ENGLISH ELECTRIC CO., Ltd. June 23, 1954 [June 23, 1953], No. 17372/53. Class 38 (4). [Also in Group XXXVII] The invention relates to control systems for a sequence of motors coupled together through a common load (e.g. a strip rolling mill drive) and automatically maintanied at a predetermined speed relationship with respect to an adjustable reference voltage. Features.-(i) Degenerative current compounding is included in the automatic control system so that if e.g. the load increases due to the motor running too fast, the current compounding signal causes the speed to be reduced. (ii) Automatic inertia compensation is provided by a flywheel pattern motor. As shown a motor M is supplied by a Ward-Leonard generator G controlled through an amplifying exciter AE in accordance with the difference between the reference voltage' across bus-bars RB (common to other motors, not shown) and the voltage of a pilot exciter PE driven by the motor. Current compounding signals are obtained from the voltage drop across the motor and generator compoles, and the inertia compensation signal from a resistance RI in series with the flywheel motor IM; both signals being applied through a potentiometer PT to a magnetic amplifier AM feeding a resistance R in the input circuit to the generator exciter AE. Adjustments.-The potentiometer PT is ganged to the master rheostat MR so that the percentage compounding of the motor is substantially independent of the mill speed. The degree of compounding may be set by rheostat RHI. The speed for the particular motor is set by the field rheostat SRI which is ganged to rheostats SR2, SR3 in the field circuits of the pilot exciter PE and flywheel motor to compensate for changes in the motor field. It is stated that the inertia compensation voltage may be derived from a winding on the generator or a transformer connected across the generator armature.

Title: Improvements in or relating to Typographic Composing Machines.
IPC: B41B25/00
Filed: 1916-12-05
Abstract: 111,703. Wigg, W., and Lanston Mono type Corporation. Dec. 5, 1916. Strip-perforating machines; justifying type.-In machines of the kind described in Specification 17199/08 having means such as described in Specifications 15999/13 and 103,338 for applying the transfer component to the character-signals, the unitsmeasuring mechanism is arranged to register the value of character-signals that are associated with the transfer component at two units less than the normal. The arrangement compensates automatically for the reduction in value of the charactersignals due to the presence of the transfer component, and thus causes the correct justification-fraction to be shown on the justification-indicator. As shown, the carrier 3a for the zero stop 3 of the units rack 2 can slide on pins 3<d> and is adjustable by means of a stepped block A, the steps A<1>, A<2> being arranged two units apart and connected by an incline. A spring C holds the carrier in contact with the block. The block is connected by a link B and a bell-crank to a handle which, in the manner described in Specification 103,338, effects the coupling of the transfer punch to the character punches and the uncoupling of the units stop for the space signal. The step A<2> normally engages the carrier, and on operating the handle, the block is depressed and allows the carrier to engage the step, A'. As applied to the construction of units-measuring mechanism described in Specification 102,825, the carrier is arranged under an arm and is supported by bolts passing through slots in the arm. As applied to the arrangement described in Specification 15989/13, the block A is operated by the lever of the pneumatic valve which controls the coupling of the transfer punch.

Title: Improvements relating to compressed fluid braking apparatus for vehicles
IPC: B60T15/18
Filed: 1960-05-18
Abstract: 902,966. Fluid-pressure braking systems. WESTINGHOUSE AIR BRAKE CO. May 18, 1960 [May 27, 1959], No. 17495/60. Class 103 (1). A compressed fluid braking apparatus ineludes a control device 5 subject to control reservoir pressure acting in opposition to control pipe and brake cylinder pressures, so as to supply fluid from supply reservoir 2 to, or release it from, the brake cylinder 7 as necessary to provide a brake cylinder pressure substantially proportional to the difference between pipe and control reservoir pressures, the device including a control reservoir charging valve 13, 14 and a valve 42, 47 which, in response to a pipe pressure reduction more than a certain extent relative to the control pressure is opened independently of valve 13, 14 to allow a discharge of fluid from the control reservoir 6. Charging with device 5, as shown, and mounted on a trailer vehicle, air at " normal pressure " in pipe 1 flows via chamber 12 to reservoir 2 and depresses diaphragm 8 to open valve 13, 14 to charge control reservoir 6 to within “ p.s.i. of the " normal pressure." When fully charged the device is again as shown. Service braking.-On a slight reduction in pipe pressure, control pressure in chamber 10 raises pistons 8, 9 to close exhaust valve 34, 35 and then open supply valve 30, 33 to connect reservoir 2 to brake cylinders 7 via check valve 4, chamber 20 and connection 21. The device returns to a lap position when brake cylinder pressure corresponds to the reduction in pipe pressure. Brake release.-Restoration of pressure in pipe 1 returns pistons 8, 9 downwards to close valve 30, 33 and open valve 34, 35 to vent brake cylinders 7 via chamber 20, passage 36 in follower 23 and exhaust chamber 17 ; if pressure is partially restored the device reaches a lap position. If pressure in pipe 1 is reduced below a certain valve, e.g. 20 p.s.i. below normal, the device 5 remains in the application position, pressure in reservoir 2 equalizing with that in the brake cylinders. Emergency braking-when pipe pressure drops by more than 25 p.s.i. (due for example to a break away of the trailer) piston 9 opens valve 42, 47 via plunger 25 and pressure flows from reservoir 6 via pipe 11, valve 42, 47 and chamber 44 to reservoir 2 and the brake cylinders. A somewhat higher braking pressure is produced and the control reservoir pressure is reduced so that should the trailer be re-coupled to truck having a lower " normal pressure " the trailer brakes are fully released on recharging as the previous higher pressure has not been trapped in reservoir 6. The reservoir 6 may be charged from pipe 1 via a check valve or a normally open valve which closes when brake cylinder pressure exceeds a small value.
