Title: A device for facilitating the putting on and taking off of stockings
IPC: A47G25/90
Filed: 1930-10-14
Abstract: 351,363. Device for putting on and taking off stockings. GENTIL GES., J. J., 5, Potsdamer Strasse, Berlin. Oct. 14, 1930, No. 30772. Convention date, Nov. 13, 1929. [Class 141.] To facilitate the putting on and taking off of stockings, particularly stockings of the surgical type, the appliance shown in the Figure is employed and is held on the foot while the stocking is drawn over it. In the case of drawing on a stocking, the appliance is removed after use through an aperture in the heel of the stocking. Instead of shaping the device to the foot, as shown in the Figure, a simplified device is described with a flat-shaped foot part and a heel part with a simpler bend. The Specification also states that the two parts may be hinged together.

IPC: D01D10/04
Filed: 1953-11-09
Abstract: <PICT:0780485/IV (a)/1> <PICT:0780485/IV (a)/2> Regenerated cellulose yarns spun from cuprammonium solutions by the funnel method are arranged immediately after spinning in warp formation and are drawn through the washing baths in this arrangement by a traction device placed after the washing baths; they are then treated in a substantially unstressed state with impregnants, excess impregnant is removed and the yarns are fed under at most a moderate tension to a drying device.  As shown in Fig. 1, the warp of yarns 1 is drawn through a washing bath 2 by a traction mechanism comprising rollers 3, 4, 5 mounted on an impregnating bath 7.  Excess impregnant is removed by a suction device 21A and the warp passes through a drying chamber 6 to a take-up device operating at the same peripheral speed as the traction mechanism.  The rollers 3, 4, 5 are positively driven and the roller 4 may be tilted about the axis of roller 3.  Each yarn passes through a groove in the suction device 21A, as shown in Fig. 4.  The impregnant may be an oil, fat, size, synthetic resin or matting agent.

Title: Analog to digital encoder

Abstract: 1,080,675. Measuring angular displacements. D.H. BALDWIN CO. July 21, 1965 [July 27, 1964], No. 31050/65. Heading G4H. Phase displaced signals 12, 14 from a plurality of photo-cells sensing markings on a disc rotating with a shaft are converted in a wave synthesizor 20 to five signals phase displaced by 36 degrees before being passed to triggers 32, 38, 44, 50, 56 which convert the signals to square wave form and also form their complements. The ten signals are then fed to a logic unit which examines the phase relationship of pairs of signals phase displaced by 72 degrees to determine the direction of movement of the shaft, a train of positive or negative pulses being sent to a reversible counter, the counter receiving ten pulses for each marking on the disc. To prevent errors due to incorrect centring of the disc four photo-cells are positioned on each side of the disc. To compensate for any change in the direct current level of the signals produced by the photo-cells, each photo-cell assembly gives out four signals phase displaced by 90 degrees and these are subtracted in pairs, the R 180  signal from the R 0  signal, the R 270  signal from the R 90  signal and vice versa.

In a heavy water moderated, boiling water nuclear reactor the lower end of the fuel assembly 3, Fig. 3, is prevented from making vibrational contact with the wall of the pressure tube 2 by the tube 20, thereby reducing wear. The assembly is supported at its upper end from a closure plug. The tube 20 is secured within the pressure tube by the shoulder 22 and resilient fingers 23. The upper end of 20 is formed of resilient fingers 32 which grip the pressure tube inner wall. The pad 34 at the fuel assembly lower end is spaced from member 20. Vibrational wear is shared between the fingers 32 and pad 34. In a further embodiment, Fig. 4, the split ring 59 is mounted at fuel assembly lower end and resiliently engages the pressure tube wall. Vibrational wear is shared by 59 and the groove in the fuel assembly in which it is retained. In the event of a breach of the coolant circuit, an emergency water supply may be conducted to spray apertures at the assembly centre. Spring loaded, dynamically stabilizing devices are mounted at the upper end of the fuel assembly and engage the pressure tube wall to centralize the assembly.

Abstract: Metal oxide gel particles, e.g. of uranium or thorium, which have been dried at a temperature not above 300 DEG  C., are rounded by wetting with a mixture of 25-75 volume per cent water and a water-miscible organic liquid, and tumbling.  A ThO2 gel, which may contain up to 10 mole per cent UO2 or up to 5 mole per cent PuO2, may be prepared by forming an oxide sol containing NO31 in the NO31/Th ratio o 0.05-0.15, and evaporating at 80-100 DEG  C.  The gel fragments are broken up and screened, e.g. to - 24, + 100 U.S. mesh (149-710 m ), corresponding to a product diameter of 100-500m . The particles may be wetted with 50-100 c.c./kg. of the solution, in which the organic liquid may be an alcohol, e.g. ethanol or a ketone, e.g. acetone.  After tumbling the particles may be fired at 1100-1200 DEG  C.  Alternatively, they may be incorporated into a BeO matrix by firing at 500-600 DEG  C., wetting with an organic liquid, e.g. an alcohol, air drying, tumbling with BlO powder of particle size below 2m , pressing, and firing at 1700-1800 DEG  C. in H2.

A roll film camera has the shutter reset and a constant length of film corresponding to one frame fed by rotation of a single shaft 8b extending outside of the camera. In one embodiment shown in Figs.2 and 3, a ratchet wheel having teeth 7 is freely mounted on a shaft 6, a segment 9 rigidly fixed to the shaft being coupled to the ratchet wheel by a spring brake band 10 which co-operates with a friction lining 11 secured to the inner surface of an annular flange of a disc 8. A film spool is engaged by an axial projection of the ratchet wheel, and the film 16 passes over a metering roller 17. A gear 18 attached to the metering roller meshes, through an intermediate gear train, with a gear 19 rigidly fixed to a shaft 19a. A disc having a notch 21a is rigidly fixed to the shaft 19a which also carries a freely rotatable disc having a notch 20a, the latter disc having a slot 22 in which a pin 23 attached to the former disc slides, a spring 24 coupling the discs together between the pin 23 and a pin fixed to the latter disc. In operation, gear 19 makes one complete rotation per frame and notches 20a, 21a are aligned after a length of film has been wound; these allow a lever 26 to pivot so that a projection 26a engages both notches, the pawl at the other end of the lever engaging the teeth of the ratchet wheel. Further rotation of the shaft 8b reduces the curvature of the brake band and no rotation is transmitted to the segment 9 and the shaft 6. A toothed gear 13 rigidly fixed to shaft 8b meshes with a gear 14 which operates the shutter changes devices. Other embodiments are described in which the brake band and friction lining drive transmitting structure is replaced by spring-loaded ball bearings, spring-loaded pivots and a ratchet and pawl arrangement. In all embodiments, a fresh length of film cannot be wound on until the shutter has been operated which causes an element 27 to pivot lever 26 out of engagement with the teeth of the ratchet wheel, at the same time spring 24 causes notches 21a, 20a to become misaligned until a fresh length of film has been wound on.

Class 41 In a process for the preparation of p-aminophenol by the electrochemical re-arrangement of nitrobenzene by the use of electrolysis and in the presence of sulphuric acid, the electrochemical reaction is effected in the presence of stannous ions. The stannous ions may be added either in the form of a stannous salt, or reducible stannic salt or a tin coating on the cathode which dissolves in the catholyte and is subsequently reduced to stannous ions. The stannous ions catalyze the reaction so as to result in greatly improved yields of p-amino-phenol. As shown an electrolytic cell comprises a lead anode 3, surrounded by a porous cup 2, a cathode 5 consisting of a copper mesh screen, anolyte 4 and catholyte 6. Specified anolytes are sulphuric acid solution, hydrochloric acid solution, phosphoric acid solution and sodium sulphate solution. The catholyte consists of a mixture of nitrobenzene, sulphuric acid and water. Specified tin salts and other sources of stannous ions which may be used are stannous chloride, bromide, nitrate, and sulphate and stannic chloride, bromide, sulphate and phosphate, stannous oxide and stannic oxide. Examples describe the carrying out of the process using stannous chloride of a tin-plated cathode.
