Title: Improvements in or relating to winding yarn
IPC: B65H54/50
Filed: 1962-08-23
Abstract: Palladium is electrodeposited from a solution containing a source of palladium ions or palladium-containing ions, a source of ammonium ions and a source of sulphamate ions of pH 5-9.  The palladium may be at least partly provided by a complex palladium compound e.g. palladium diammino disulphamate, palladium diammino sulphate, ammonium palladous-dinitrito disulphamate, ammonium palladous dinitrito sulphate, disulphamato-dinitrito palladous acid, sulphato-dinitrito-palladous acid.  An aqueous solution containing Pd(NH3)2 (NH2SO3)2 and Pd(NH3)2SO4 is prepared by reacting Pd(NH3)2(NO2)2 with sulphamic acid at below 50 DEG  C. and pH above 5 by addition of ammonia. NH4NO2 is also formed. An aqueous solution containing Pd(NH3)2 (NH2SO3)2 and NH4NO2 and (NH4)2Pd(NH2 SO3)2(NO2)2 is obtained by reacting Pd(NH3)2 is obtained by reacting Pd(NH3)2 (NO2)2 with NH4NH2SO3 at above pH 5 and below 50 DEG  C. In an example NH4NH2SO3 was dissolved in water and the pH adjusted to 7 by addition of ammonia. Palladium diammino dinitrite in ammonia was added and also Ni NH2SO3 and the pH adjusted to 7.3-7.8 by addition of sulphamic acid.  The bath composition may be in grams/litre: Pd (calculated as metal) 4-100 NH4NO2 4-100, NH4 NH2SO3 20-160, Ni(NH2SO3)2 0-1 ammonia to give pH 6-8 and the working conditions are: temperature 15-35 DEG  C., strike voltage 2-4, working voltage 1.3-1.8, current density 2-40 amps/sq. foot, cathode efficiency at 35 DEG  C. at least 95% or at 5 amps/sq. foot 34 mgms. of Pd/amp. min. The anodes may be of platinum or palladium and the vessel containing the electrolyte may be made of or lined with glass, " Perspex " (Registered Trade Mark), polyethylene, polyvinyl chloride or austenitic stainless steel.  Printed circuit boards may be plated in the solution (see Division H1).

Convention dates, Nov. 14, 1933, Nov. 17, 1933, and Nov. 30, 1933. [Class 40 (iii)] The rapid component of scanning is given by a cathode ray beam oscillating over a line F1, F2, while a rotating mirror M provides the slower scanning component. The line F1, F2 may be defined by a narrow slit in a shutter. The mirror drum may be replaced by a lens disc and the image may be projected on a ground glass screen. The synchronous motor S controls the movement of the cathode ray. The ray may be modulated in intensity by causing the rectified or unrectified signals to deflect the ray at right angles to the line F1, F2 and so vary the area of the luminous spot. A steady voltage superimposed on the modulating potentials may be used to invert the image and also control the average intensity. The complete picture may be built up in one rotation of the mirror drum or by each mirror of the drum.

Title: Improvements in or relating to cylindrical pin-and-box type threaded couplings
IPC: F16B33/02
Filed: 1956-10-29
Abstract: 801,456. Rod &c., couplings. DE BATAAFSCHE PETROLEUM MAATSCHAPPIJ,N. V. Oct. 29, 1956 [Oct 31, 1955], No. 32953/56 Addition to 786,652. Class 99(1). [Also in Group XXIV]. In a pin-and-box coupling for pipe-lines or a well-drilling string, the pin 2 and the box 4 being provided with cylindrical screw-threads 5 and 6 respectively, at least one of the screwthreads, when unloaded, deviates from a normal cylindrical screw-thread in such a way that, after the box has been shrunk tight around the pin, the outer flanks of the screw-thread 5 and the inner flanks of the screw-thread 6 are more heavily loaded than the other flanks of the screw-threads. A normal cylindrical screw-thread is defined as one in which the pitch and the flank diameter are uniform throughout, or one in which the pitchis uniform and the flank diameter varies so that there is a taper over part or all of the length of the screw-thread of less than one degree, the flank diameter being equal to twice the radial distance from the axis of the screw-thread to the middle of the flank ; also, the inner and outer flanks are defined as those flanks which are directed respectively away from and towards a plane M normal to the longitudinal axis of and bisecting the length of the screw-thread. The screw-threads of the pin and box, when unloaded and cold, may have the same pitch, the middle of the screw-thread on either or both the pin and box being provided with a local variation of pitch at the plane M, and the difference between the flank diameters of the screw-threads being greater at the middle of the latter than at the ends thereof. Alternatively, (a) both screw-threads may have a constant pitch, that of the screw-thread of the pin being greater than that of the screw-thread of the box, in this case, the difference between the flank diameters being smaller at the middle of the screw-threads than at the ends of the latter, and (b) the screw-thread of the pin is of greater pitch than the screw-thread of the box, the difference in pitch decreasing from the middle of the screw-threads towards both ends thereof, preferably the decrease of the difference in pitch being continuous and the box being provided with a normal cylindrical screwthread. As shown in Fig. 1, there is a helical slot between the unloaded flanks of the screwthreads 5, 6. In the embodiment shown in Fig. 5, the pin 15 has a shoulder 16 which bears against a shoulder 18 provided on the box 17 ; the lines 19 and 20 extending from the shoulders 16, 18 and the flank 21 intersect on one side of the axis 22 of the coupling so that a good fluid seal may be obtained between the shoulders. Specification 799,028 is also referred to.

Abstract: 285,004. Humphreys & Glasgow, Ltd., (Assignees of Soc. de Construction d Appareils pour Gaz Ó l'Eau et Gaz Industriels). Feb. 8, 1927, [Convention date]. Producers.-Steam and oxygen are supplied to a gas producer during up- or down-steaming so that the heat generated by the oxygen maintains the fuel bed sufficiently hot for the continued generation of water gas by the steam. The fuel bed is first blasted up with air or oxygen admitted through a valve 24. For upsteaming, valves 14, 19 and 20 are opened and steam supplied through pipe 13 and oxygen through valve 17, the proportions of the mixture being controlled by valves 15, 21 in accordance with the indications of meters 11, 18. Valve 6 being closed, the oxygen-steam mixture enters by a pipe below the grate, and the gas passes out from the top of the producer and through a combustion chamber 2. If a subsequent down run is required the proportion of oxygen in the uprun is increased to heat the fuel bed sufficiently to enable water gas to be generated by supplying steam only through pipe 10 to the top of the producer. An oxygen escape pipe 22 is provided to prevent any oxygen which may have leaked from calva 19 from getting into the pipe 4.

Abstract: 429,612. Dispensing liquids and gases. FRANCIS, E. M., 36, Heathcote Grove, Chingford, Essex. Dec. 4, 1933, No. 34030. [Classes 8 (i) and 102 (ii)] In apparatus for dispensing gases or liquids, of the type in which fluid is expelled from a chamber a, Fig. 4, by distending a bladder d by means of an air pump f, fluid is drawn into the chamber a by releasing the pressure in the bladder by means of a valve e. The fluid to be dispensed may be drawn into the chamber a, or into a separate container l. In the former case the bladder may be shielded from the fluid by means of a partition with a connecting passage. As shown two jars a l are clamped between a base o and a cover n by means of bolts p. The cover carries the pump f, the air pipe b and the fluid discharge pipe c, and is formed with a passage m connecting the vessels a, l. Fig. 6 shows apparatus for transferring liquid from a bulk container to an accumulator cell w. A stopper x, inserted in the cell, carries a pipe y to the bulk container and a pipe m to a chamber a. The latter contains a diaphragm d\ which may be elastic, or acted on by springs. The diaphragm is expanded by air from a pump f to expel air from the cell w. The pressure behind the diaphragm is then released by means of a valve e, whereupon liquid is drawn into the cell w from the bulk container. The apparatus shown in Fig. 4 may also be used for transferring liquid from a bulk container by the employment of a Y-fitting provided with stop cocks.
