Filed: 1927-04-12
Abstract: 269,543. Verein f³r Chemische Industrie Akt.-Ges. April 15, 1926, [Convention date]. Acetic acid.-Precipitated acetyl cellulose is pressed to remove acetic acid and produce a coherent band which is then washed and pressed alternately, after which the material may be rapidly dried. The washing may be in countercurrent. Precipitated acetyl cellulose a from a store tank in the form of more or less thickened pulp passes into a conduit b having a raised breast portion up which the pulp is fed by a vaned wheel c and passes through a conduit o on to a travelling endless film or band d. The mass passes under a freely mounted roller e which removes unevennesses, and then through a preliminary press f, and a main press q which may be of granite or acid-resisting steel, the band then having about 50 per cent dry material. The acid expressed collects in a tank 1. The pressed band then passes from the. endless band d to an endless band d' which carries it through washing tanks h, h<1>, h<2>, h<3>, a pressing-roller k being arranged at the outlet side of each tank to remove the wash-water. A travelling covering-felt i may be arranged above the band d' to keep the acetyl cellulose band a in contact with its supporting band d<1>. The washing water travels through the tanks in counter-current to the material. The washed band is passed over heated drums similar to those used for drying paper, the band a being carried round the drums by a band d<2>. The Specification as open to inspection under Sect. 91 (3) (a) is not limited to the treatment of the cellulose acetate, in the form of a band but includes the pressing of the precipitated material after which it may be washed and again pressed as many times as necessary. This subject-matter does not appear in the Specificaticn as accepted.

Title: Improvements relating to wet processing
Inventor: HELLIWELL GUY STORR
IPC: D06B5/16
Filed: 1953-04-14
Abstract: <PICT:0744418/IV(c)/1> In apparatus for wet-processing textile materials of the kind comprising a closed circulatory system, the treatment liquid being circulated through a kier 1 by means of a pump 7, hydrostatic pressure is applied to the circulatory system at the suction side of the pump by means of the head of liquid, e.g. water, contained in a pipe 15 and open-topped tank 17.  The articles to be processed, which may be packages 3 to be dyed, are arranged on spindles 4 in the kier 1.  During the initial process valves 12 and 14 are opened and valve 16 is closed and the liquid is commenced circulating through the kier 1, pump 7, heater 9 and two-way valve 8. Trapped air escapes through the pipe 13, any excess liquor also being discharged through the pipe 13 into the open-topped expansion tank 10.  When the initial clearing run is completed, the valves 12 and 14 are closed and valve 16 is opened so that the liquor is cycled in a closed circuit and is subjected at the same time to the head of pressure maintained by the tank 17.  This excess pressure assists the pumping action thus enabling a smaller pump to be used than would be otherwise possible.  By choosing the pressure head correctly evolution of vapour within the kier at the temperature of operation may be prevented, while the danger of excessive pressure arising if the temperature should increase is reduced.  In a modification, Fig. 2 (not shown, the tank of 17 is connected into the system through the expansion tank 10.

Title: Improved method of and installation for making x-ray exposures
IPC: H05G1/24
Filed: 1935-04-06
Abstract: 437,093. R÷ntgen -ray apparatus. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, Emmasingel, Eindhoven, Holland. April 6, 1935, No. 10724. Convention date, April 6, 1934. [Class 39 (i)] In the making of X-ray exposures a condenser is first charged during a number of cycles from an alternating current source through a rectifier and is then discharged through the tube, this discharge being supplemented by a supply from a continuously operating source for example from a high voltage transformer with a rectifying device ; during the condenser discharge the internal resistance of the tube is raised either by reducing the temperature of the cathode or by varying the potential of an auxiliary electrode arranged within the tube and controlling the anode currents. A two position switch 1 and time-controlled switch 2 controls the connections of the apparatus ; in the position I of the switch 1, the transformer 10 for the cathode 9 is connected to the mains 16, 17 through two adjustable resistances 11, 12, Fig. 1, and the high tension transformer 5 is connected to the tube through the four rectifiers 6 arranged in a bridge circuitfor fluoroscopic exposures under control of the operator's switch 19. With the switch 1 in position II the whole or part of the resistance 12 is first short circuited and a vacuum switch 14 in the tube circuit is opened, its actuating coil 15 being energized ; the circuit of the coil 15 is completed through the contacts 29, 30 of the time switch 2. The actuator 3 of this switch is in circuit and delays movement of the contact arms, until the condenser 7 has been charged. The movement of these contacts allows the switch to close and if desired after further delay the short circuit about the resistance is removed thereby raising the internal resistance of the tube ; if desired the cathode heating circuit may be opened. To prevent unwanted discharge of the condenser into the tube, short circuiting contacts 34 are provided, the coil 35 therefor being energized with the switch in position I when the control 19 is closed. The transformer may have a switching arrangement for disconnecting from the mains after condenser discharge. The transformer may be connected to the condensers and tube through a single valve. Reactances 8 are included in the condenser circuit. In a modification the potential of a control electrode 37, Fig. 2, surrounding the cathode is varied to alter the internal resistance of the tube, the biassing being effected through a transformer 38, in whose secondary is included a rectifier 39, a condenser 40 and if desired a resistance 41, the condition of the condenser is shown by a glow discharge lamp 42. In position I of the main switch the condenser 40 is charged and the internal resistance of the X-ray tube is high, in position II the condenser 40 is discharged by means of a short circuit to reduce the tube resistance, the short circuit being temporarily removed by the time switch 2.

In a brake for a vehicle having at least two axles a brake force distributer includes two rollers 10a, 10b, Fig. 2, each carried by a rod 12a, 12b and rolling along each face of a plate 11 which is interposed between a floating balance rod 9 and a control member 3, means pivoting a regulating lever 17 through an angle proportional to one axle load the proportionality being dependent on the other axle load and means interconnecting the two rods, the plate and the regulating lever whereby, under varying loads the two rods and the plate are displaced to vary the point of application of the control member on the balance rod. Brake pedal 1 controls via a rod 2 the pivoted lever 3 which acts through the rollers 10a, 10b and plate 11 on the floating balance rod 9 to control the slide valves 6a, 6b of a distributer connected to the front and rear wheel braking circuits through conduits 8a, 8b. The rods 12a, 12b and plate 11 are pivoted to a lever 14 fixed on a pin 15 carried by a support 5. As the front axle load increases, a lever 18 is moved in direction of arrow 22 to rotate lever 17 and lever 14 in direction of arrow 23. This causes plate 11 to rotate the rollers 10a, 10b whilst displacing them by half its own displacement. The point of application of the control force on balance rod 9 is displaced towards slide valve 6a to cause a front/rear differential braking effect. When the rear axle load increases a rod 24 moves a slotted member 19 towards the pin 15 so as to reduce the effective length of lever 17, thereby increasing the effect of load variations on the front axle. Lever 18 and rod 24 may be connected to a piston or bellows in a fluid suspension system.
