Abstract: 703,036. Roller bearings. BRITISH TIMKEN, Ltd. Sept. 15, 1952 [Feb. 7, 1952], No. 3209/52. Class 12(1) An X type roller bearing or a roller bearing cage for such a bearing has its rollers 3 and 3<SP>1</SP> located in the triangular section cage 4, Figs. 1, 2, 3, by means of wire loops 10 sprung into diverging grooves 9 in lands 8 between the roller pockets 5. After assembly of the loops 10 into one side of the bearing the latter may be turned over and the opposite side assembled in the same way; the grooves 9 may however be cut parallel to each other throughout their depth and the loops caulked into the grooves. In a modification the loops 10 are replaced by strips or bars 11, Fig. 11, fixed into the grooves by caulking &c. and having extending portions 11<SP>1</SP> to retain the rollers. The retaining members, may also be of U shape or other form, long U-shaped members being employed, the closed end overhanging one pocket and the free ends of the branches overhanging another pocket. In a further modification the retainers may be provided at both the top and the bottom rolling surfaces of the rollers. Specification 689,261, which is referred to, describes and shows the roller cage 4 for use in X type roller bearings.

Abstract: 113,836. Insull, M. J. March 8, 1917. Metals, powdered, obtaining coherent masses from.-Unsintered tungsten powder is subjected to pressure, preferably greater than 130 tons per square inch, to obtain a solid having a density greater than 15 and, in some cases, above 17. Articles such as chemical dishes may be made out of the solid so prepared. After the compressing process, the pressure upon the tungsten powder is relieved so as to allow the powder to expand substantially equally in all directions. In the apparatus shown, the powder is placed in a cell 12 formed by a bottom plate 15, lateral wedge-shaped blocks 17, 18, and end wedge-shaped blocks 21, 22. The blocks are fitted to slide vertically in inclined side walls 14, 23 of the die 4, but during the compression are held by plates 19 and screws 20. The punch has a pressing-plate 11 secured in a slot in a block 7, which is carried by a plate 6. After the powder has been compressed, the plate 11 is raised slightly and, at the same time, the plates 19 are released.

Abstract: 544,470. Insulation for dynamo-electric machines. BRITISH THOMSON-HOUSTON CO., Ltd. March 14,1941, No. 3476. Convention date, March 15,1940. Drawings to Specification. [Class 35] The windings of a dynamo-electric machine are bonded into an integral mass by polyvinyl chloride plasticized by the addition of, for example, 15-40 per cent. of tricresylphosphate. The wire has a coating of an organic enamel, preferably a condensation product of a hydrolyzed polyvinyl ester and an aldehyde, and liners, wedges and coil separating partitions may be made of paper or other substances which form with polyvinyl chloride a moisture resisting compound of high dielectric strength. The polyvinyl chloride composition is extruded preferably from a hot mass on to the wire, which is brought to the same temperature by a gas-flame; or it may be wrapped on in tape form or applied in solution. When the core is fully assembled, heating current is passed through the windings and the whole is fused into a single moisture, oil, and vibration-proof mass.

Title: Process for the oxidative preparation of iodine
Inventor: KING RALPH WILLIAM
IPC: C01B7/14
Filed: 1964-01-28
Abstract: <PICT:1005476/C1/1> Iodine is prepared by oxidizing an aqueous iodide-containing solution using oxygen in the presence of nitrogen dioxide as catalyst at a temperature greater than 40 DEG  C. up to 20 mole per cent of catalyst based on the iodide to be oxidized may be used. The NO2 may be introduced separately or together with oxygen or it may be formed in situ by adding NO, N2O4, HNO3 or an alkali metal, e.g. Na or K, nitrite either separately or with one of the reactants. Oxygen or air may be introduced into the reaction mixture at several points with stirring or shaking.  Alternatively, the iodide solution may be sprayed into an oxidizing atmosphere or the gaseous oxidant may be used to atomize the solution.  The pH of the iodide solution may be equal to or less than 7.  The partial pressure of oxygen is at least 0.5 atm. abs. and the total pressure less than 10 atm. abs. The temperature of reaction is between 40 DEG  and 140 DEG  C. Iodine may be separated from the reaction mixture by settling or by stripping with, say, nitrogen, air, or steam.  Iodine in the gases may be recovered by washing, e.g. with aqueous NaOH, Na2CO3, or NaHCO3.  The iodide solution may be that resulting from the preparation of C4-C6 alkadienes from more saturated hydrocarbons by dehydrogenation with iodine and/or iodine compounds.  Zone I heats the iodide solution before passing into the oxidation zones II and III which are of steel or tantalum or glass lined.  Oxygen is introduced at 4 and HNO3 at 3. The effluent gas may be removed from Zone II by line 18 or recycled to Zone III by line 17.  The liquid from the oxidation zones passes to the stratification Zone IV.  The iodine layer may be removed at 8. The aqueous upper layer passes to the stripping Zone V where steam is introduced at 10.  A mixture of steam and the remaining iodine from the solution passes into the cooling Zone I and is absorbed by the Hl solution introduced by line 1. Iodine-free liquid may be withdrawn at 16 or water cooled in 13 whence part may be added to the iodide solution feed.  In a modified apparatus, Fig. II (not shown), the effluent gases from the oxidation zones are passed successively through a washing tower and absorption tower.  In the washing tower water is introduced at the top and the iodide solution containing HNO3 is added at the mid-point before entering the oxidation zones. Specifications 895,500, 911,212 and 943,806 are referred to.

Abstract: 1421291 Radionavigation SOC D'ETUDES RECHERCHES ET CONSTRUCTIONS ELECTRONIQUES 25 Jan 1973 [23 March 1972] 3861/73 Heading H4D Relates to a phase-comparison hyperbolic radio navigation system, e.g. OMEGA, comprising at least two spaced stations A and B each sequentially transmitting signals of frequency 10À2 and 13À6 kHz such that the phase difference between the 10À2 kHz signals as received at a mobile station defines a set of narrow hyperbolic lanes and the so-called lane identification differential phase (corresponding to the phase difference between the 3À4 kHz beat frequencies derived from the pair of different frequencies transmitted by each station - A and B) defines a corresponding set of wide lanes, each wide lane including three narrow lanes. According to the present invention said lane identification signal from unit 10, Fig. 1, is automatically corrected for frequency dispersion errors in a unit 12 by a correction signal C derived from the narrow lane number N as given by an integrating phasemeter 7 responsive to the 10À2 kHz signals and the resultant corrected analogue differential phase signal V (DPS) is applied to a moving pointer indicator 122, Figs. 3 and 4, whose full scale deflection (corresponding to one wide line) is produced by a voltage V o , a bias voltage S being applied to the indicator 122 such that the resultant deflection signal V (DPS)-V o  is always less than V o  and said bias signal S being produced by applying the signal V (DPS) in parallel to four comparators 123-126 having respective reference signals 2V o , V o , O and - V o , the output from each comparator being +2 2 or - 2V o  according to whether the signal V (DPS) is greater or less than the corresponding reference signal and the outputs from the comparators 123-126 being summed via resistors R such that the maximum and minimum values of the bias signal S are + 2 and - 2V o . With such an arrangement the validity of the narrow lane number N can be checked by dividing said number by three, since the resultant remainder should correspond to the reading of indicator 122. The differential phase signal V (DPS) can be produced (i) as shown in Fig. 1, by combining a 10À2 kHz phase difference signal with a corresponding 13À6 kHz signal or (ii) by phase comparison of actual 3À4 kHz beat frequencies. If the wide lane number is in doubt, a corresponding lane identification process is effected using the 1À13 kHz beat frequencies between the 10À2 kHz signal and additional transmitted 11À33 HHz signals.
