Title: Self-aligning bearing
IPC: F16C35/077
Filed: 1953-01-29
Abstract: 719,194. Self-aligning bearings. COMERY, P. D. Jan. 29, 1953 [Feb. 1, 1952], No. 2603/53. Class 12(1) A self-aligning bearing arrangement comprises a shaft 10, Fig. 1, mounted in bearings 11 supported in a housing 14 provided with a flange 15 the outer surface 16 of which is curved with a radius R. An element 19 positioned between thrust surfaces 15a and 20a is confined against radial expansion by the machine frame 18, and comprises a series of wedge-shaped blocks 30, 31 in interengagement as shown to provide the selfaligning action. The blocks are loosely threaded in the manner of beads on a bracelet on a double wire 32, so that when they are moved axially relatively to one another from the Fig. 1 position, the circumference of their circumscribing circle is increased. Springs 25 around the bearing are supported by the flange 15 and closure plate 23 and are provided to keep the flange 15 and shoulder 20 in contact with the element 19 under conditions of slight reverse thrust. In operation, thrust is transmitted from the shaft 10 directly through the bearings 11 to the housing 14 and thence through the flange 15 and the element 19 to the machine frame 18. Under the influence of the load each block of the element is urged, like a wedge, between the inclined lateral faces of adjacent blocks, thereby tending to increase the circumferential length of the element. However, the wall 17a of the recess 17 confines the element against radial expansion. Any small mis-alignment of the shaft is absorbed by deformation of the element 19, the clearances 42 and 43 on one side of the assembly being reduced while the corresponding clearances on the diametrically opposite side of the assembly are increased, by a sliding action between the faces 40, 41, of adjacent blocks and a circumferential displacement progressively from block to block around the element. It is desirable that adjacent blocks should be made of dissimilar materials, such as bronze and steel, as a precaution against seizing. Specification 659,526 is referred to.

Title: Improvements in charging arrangements for electric accumulator vehicles
IPC: H02J7/32
Filed: 1942-03-02
Abstract: 549,784. Charging batteries. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET and SCHMIT, W. G. March 2, 1942, No. 2704. Drawings to Specification. [Class 38 (iv)] A series wound traction motor of an accumulator vehicle is utilized to charge the accumulators from A.C. mains by exciting the series field through a dry rectifier. The armature may, as a motor-generator, be driven preferably in a reverse direction, by a three phase motor or, as a rotary converter, by A.C. fed into slip rings. When the motor used is an auxiliary machine coupled to the main motor drive through a free wheel, the auxiliary motor pinion incorporates a free wheel so that the gearing is not driven when charging. A relay responsive to the armature voltage when the machine is generating may energize a relay completing the charging circuit and energized from the A.C. mains, so that charging stops on failure of the mains supply and restarts automatically on restoration.

Abstract: 939,430. Electrostatic flocking. L. T. F. BRYAN. April 24, 1962 [Jan. 24, 1961], No. 2814/61. Class 93. An article is coated electrostatically with a fibrous material by fluidizing the particles of fibrous material in a chamber and conveying them while fluidized to a device for electrostatically charging the particles and directing them to the article, the electrostatic forces being such that the deposited particles are attracted to the device so that they are maintained upstanding from the article by the forces of attraction. The device for charging the fibrous particles is preferably a tubular nozzle into which the fluidized flock is conveyed and in which the particles become charged as they pass along the nozzle, which is suitably connected to a suitable source of high-tension current. As shown (Fig. 1), an electrostatic " gun " 10 comprises a nozzle 11 from which the flock is discharged. The flock is delivered to the nozzle by a hose 12 connected to a chamber 13. A source of hightension 14 is connected to the gun by leads 15 in order to charge the flock. Air under pressure is directed downwardly into the chamber 13 through a jet 17 into the mass of flock, thus maintaining a considerable quantity of flock in a fluidized state in the chamber. The air from jet 17 carries the fluidized flock from the chamber along the hose 12. The supply of air to the chamber is controlled by a solenoid actuated switch 18 which is energized by a trigger switch 19 which also connects the high-tension supply 14 to the nozzle. The article to be coated may be provided with an adhesive coating in order to attach the flock thereto. Various modifications are also described.

Title: Improvements in and relating to the production of polymers of formaldehyde
IPC: C08G2/00
Filed: 1942-03-04
Abstract: 557,873. Resinous polymerization products. DU PONT DE NEMOURS & CO., E. I. March 4, 1942, No. 2837. Convention date, Aug. 26, 1940. [Class 2 (iii)] Anhydrous formaldehyde is polymerized at - 20C. to +30C. in an inert solvent containing from 0.05 to 5.0 molar per cent. (calculated on the formaldehyde) of an aliphatic acyl ketene and from 0.01 to 2.0 molar per cent. of an isocyanate or isothiocyanate. The ketene is defined by the formula R R 1 # C = CO in which R is an acyl radical and R<SP>1</SP> is an aliphatic residue. Examples are propanoylmethyl-, butanoylethyl-, pentanoylpropyl-, octanoylhexyl- and dodecanoyldecyl-ketenes. Suitable isocyanates or isothiocyanates include methyl, ethyl, propyl, butyl, amyl, hexyl, heptyl, decyl, octacedyl isocyanates and isothiocyanates, tetramethylene diisocyanate, hexamethylene diisocyanate and diisothiocyanate, phenyl, naphthyl and cyclohexyl isothiocyanates and phenylene, naphthylene and cyclohexylene diisocyanates and diisothiocyanates. Suitable solvents are dimethyl, diethyl and diisopropyl ethers, methylene chloride, methyl chloride, chloroform, carbon tetrachloride, trichlorethylene, tetrachlorethylene, dichlorethane and chlorobenzene. In an example anyhdrous formaldehyde is distilled in an atmosphere of nitrogen into a cooled pressure vessel containing methylene chloride, n-octanoyl-n-hexyl-ketene and hexamethylene diisocyanate. A pressure of 25 atmospheres of nitrogen is applied, the vessel sealed, allowed to warm to 0-10C. and allowed to stand for 24 hours. The pressure is released and the solvent evaporated from the polymer. The polymer may be freed from formaldehyde and its lower polymers by extraction with methyl alcohol, acetone, dilute aqueous ammonia, aqueous formamide and dilute aqueous solutions of strong alkalis. The polymer may be modified by reaction with esterification and etherification agents such as acid anhydrides and alkyl sulphates. Plasticizers may be incorporated by digesting the powdered polymer with a solution of the plasticizer dissolved in an aromatic hydrocarbon or chloroform. Suitable plasticizers are #- phenoxyethanol, tetraethylene glycol or its dimethyl ether, diphenyloloctadecane, diethylene glycol dicresyl ether, polyethylene oxide, #-hydroxyethyl-o-methoxybenzamide, dimethoxyethylphthalate, dibutyl phthalate, triethylene glycol dihexoate and the cyclohexanone ketal of glycerol. Phenols, cresols, resorcinol, 1.12-diphenyloloctadecane, amides, casein, starch, urea, fillers, e.g. wood and cork flour, mica and clay, pigments and other polymers may also be added. The products are particularly suitable for the production of moulded articles, e.g. buttons, combs, hollow-ware and panels.

Title: Improvements in or relating to apparatus for collecting in closed vessels condensed water discharged by heating apparatus
IPC: F24D19/08
Filed: 1930-01-28
Abstract: 337,302. Taglietti, U., and Tasso, A. Jan. 29, 1929, [Convention date]. Heating by circulation of fluids.- In a condensate collecting apparatus communicating with a number of groups of steam heaters each group working at different pressures on the closed cycle system and connected to independent collectors, the latter release their excess steam or discharge excess condensate to a heat accumulator. The collector of the low pressure group works as a continuous discharger of the accumulator. The steam heaters 1-1 - - 3-3 working at high, medium and low pressures discharge their excess steam and condensate to the collectors B<1> - - B<2>, respectively, from which the liquid is pumped to the boiler by the pumping apparatus 30 - - 32. Excess condensate passes from B<1> and B<2> to the accumulator P through pipes 18, 19 and excess steam through safety valves VS', VS<2> to the same reservoir. The low pressure collector B<3> and the accumulator are at the same pressure, condensate discharging from the latter to the former, which also receives excess condensate and steam from the low pressure group 3-3. The pressure in the latter is kept beneath a suitable limit by adjusting the pressure in the accumulator. This may be effected by automatic iniection of cold water under pressure into the accumulator, the supply being controlled by a valve actuated by the pressure existing in the accumulator; or by combining with the accumulator a tubular heat exchanger having cold water circulating through the tubes; or the accumulator may work as an intermittent steam generator or as a continuous generator in a secondary steam heating plant. Specification 295,104, [Class 102 (i), Pumps &c.], is referred to.

Title: Method and apparatus for measuring and indicating the quantity of liquid in a container
IPC: G01F17/00
Filed: 1924-02-06
Abstract: 226,695. Burness, T. P. N. Feb. G, 1924. Indicating by measuring volume or pressure of air above liquid.-The volume of liquid in a container is measured by trapping a column of liquid with air above, the level of the trapped liquid corresponding to that in the container, and then reducing the volume of the trapped fluids by a predetermined amount, and measuring the air pressure. A tube a carries an annular chamber b at its lower end, which is mounted on a spigot f communicating by a pipe g with the container h. Orifices j in the tube a are at the level of the bottom of the container. A piston k is normally below the orifices j, and is mounted on a rod l passing through a stuffing-box m. A sleeve n limits the upward movement of the rod l by engagement with the stuffing-box. A sleeve r surrounds the tube a and is attached to the rod l by a cap q, and has a slot v to allow vertical movement over the pipe u. The tube a communicates with the air by means of openings p, o. Liquid in the tube a is normally at the same level as in h, so that when the sleeve r is lifted the openings j, p are closed and the column of liquid and air is trapped. The air is compressed until the piston reaches its upward limit, and the pressure is measured by a gauge t which may be calibrated to indicate the corresponding volume of liquid in the container b. Alternatively, the upper part of the tube a may be connected to the upper part of the container h instead of to the air, in cases in which the liquid is maintained under gas pressure.

Abstract: 607,357. Drawing; - rolling; extruding. KRYSZEK, S., and HARD ALLOYS, Ltd. Jan. 31, 1946, No. 3141. [Class 83 (iv)] In a method of mounting a tungsten carbide or similar hard metal element comprising, for example, a drawing or extruding die or a hollow cylinder forming the working surface of a roll in a rolling mill, the element is associated with a central supporting member or is positioned within an annular supporting casing and the space between the element and - the supporting member or casing is filled with hydraulic fluid under pressure so as to oppose the tendency for the element to burst under the application of pressure to its working surface. Fig. 1 shows the invention as applied to a die element 1 of hard metal mounted between gaskets 8, 9 in a support comprising a base 2, side walls 3 and a cover 4 bolted thereto. An annular space 7 left between the side walls 3 and the outer surface of the element 1 is filled with hydraulic fluid through a hole 12 in the cover 4, the pressure of the fluid being adjustable by a screw 14 operating through a diaphragm 15. In a modification, instead of the fluid being admitted directly to the space 7, an envelope of rubber or other resilient - material is inserted in the space and filled with pressure fluid. As shown in Fig. 3, an annular hard metal plug 19 may be supported between gaskets 26, 27 at the end of a mandrel 20, the space 21 between the plug and a reduced portion of the supporting mandrel being fed with hydraulic fluid through a passage 28. A roll for a rolling mill may comprise a hard metal cylindrical shell supported at its ends and, if desired, at intermediate points also on an axle and the space between the shell and the axle being supplied with pressure fluid. In any of the above forms, the pressure of the fluid may be varied automatically in accordance with the pressure applied to the working surface as by supplying the fluid from a pump through a valve electrically controlled from a motor operating the drawing carriage or other machine part.
