Abstract: 117,153. Stagg, T. D., and Osborne, F. E. July 24, 1917. Pulleys and driving- drums.-In a built-up wheel or pulley, the spokes e are of U-shape, with their outer ends formed as tangs f recessed into the rim h and the curved inner ends tightly engaging recesses formed by curved webs d, d<1>, projecting from a flange c un the hub a. The webs d, d<1> may converge to form taper recesses, and may be formed with ribs o as shown in Fig. 1; or each spoke may be formed in two parts abutting against a transverse wall in the hub recess. The hub flanges k, k, secured by transverse bolts j preferably passing through the spokes, are formed with ribs r embracing the webs d, d' so as to relieve the bolts j of driving &c., stresses. The wheel shown in Figs. 1 and 2, comprises two such sets of spokes arranged to break joint. In a modification, the wheel comprises one set only of curved spokes with alternating straight radial spokes. An outer tyre i is shrunk &c., on the rim h, and further to consolidate the wheel, tension-rods l (Fig. 5) connected at their inner ends to the hub a or to a ring b, are threaded into straining-nuts m housed in the rim.

Title: Pharmaceutical compositions containing dioxolanes
IPC: A61K31/445
Filed: 1965-03-15
Abstract: 2 - Piperidyl - 1,2 - ethanediol hydrochloride is prepared by catalytic hydrogenation of 2-pyridyl-1,2-ethanediol hydrochloride in water using a platinum oxide catalyst, the product being recrystallized from isopropanol.  2,2 - Diphenyl - 4 - (2 - piperidyl) - 1,3 - dioxolane is prepared as the hydrochloride salt by reacting 2 - piperidyl - 1,2 - ethanediol hydrochloride with dimethoxyphenylmethane, at elevated temperature in isopropanol, while passing dry hydrogen chloride into the reaction mixture.  The required product forms a precipitate, which is extracted with ether and the residue recrystallized from ethanol and then ethereal methanol to give the pure product, M.Pt. 248-252 DEG  C. The alpha racemate of this compound is prepared by extracting the residue from the ether extraction in the above procedure, with hot ethanol and filtering, to give a filtrate and an ethanol insoluble residue; the solution is chilled and the resulting crystals recrystallized from methanol until the pure alpha racemate is obtained, M.Pt. 256-260 DEG C.  The beta racemate is derived from the said ethanol insoluble residue by continued recrystallization from methanol until a product having a constant melting point of 301 DEG  C. is obtained. Resolution of the racemates is effected by converting 2,2 - diphenyl - 4 - (2 - piperidyl) - 1,3-dioxolane hydrochloride to the free base, and reacting this base with L-(+)-tartaric acid in methanolic solution, when the L-(+)-tartrate of the dextrorotatory base crystallizes out.  The mother liquor is converted back to the free base and by similar means, using D-(-)-tartaric acid, the levorotatory base D-(-)-tartrate is prepared. Both tartrates are then converted to the corresponding hydrochloride salts.  The dioxolanes are for use in pharmaceutical compositions (see Division A5).ALSO:Analgesic compositions comprise 2,2-diphenyl-4-(2-piperidyl)-1,3-dioxolane <FORM:1093583/A5-A6/1> or the a - or b - racemate, or a stereoisomer, or physiologically acceptable acid addition salt thereof, in admixture with one or more of the following: caroisoprodol; reserpine; chlordiazepoxide; imipramine hydrochloride; pheno-, buta-, or amo-barbital; chlorphenesin carbamate; chlorpromazine hydrochloride; meprobamate; dl-monobasic amphetamine phosphate; ectylurea; methscopalamine bromide; methylprednisolone; hydrocortisone; prednisolone; prednisone; aspirin; phenacetin; acetyl-p-aminophenol; codeine; medroxyprogesterone; hydroxyprogesterone acetate; ethoxzolamide; and hydrochlorothiazide.  The compositions are preferably in a unit dosage form for oral administration.

Title: Improvements in or relating to the cracking of liquid hydrocarbons
IPC: C10G9/40
Filed: 1929-04-10
Abstract: 336,269. Lucas, O. D. April 10, 1929. Hydrocarbons, cracking.-Oils are raised to the cracking temperature by indirect contact with liquid diphenyl or diphenyl oxide in a heat exchanger, the said heating liquid being contained in a closed system to which heat is supplied outside the heat exchanger. The oil may or may not be heated directly, as in a pipe-still, before entering the heat exchanger. Oil from a tank A passes through a cold oil pump B to a pre-heating coil X in a dephlegmator H; a part of the oil may also be heated in a low pressure heat exchanger K. The pre-heated oil is mixed in a vessel O with oil from the dephlegmator H, and passes through a pump P to a coil D located in the cooler part of a pipe-still C ; it is then raised to cracking temperature in a high pressure heat exchanger F by indirect contact with diphenyl (or diphenyl oxide) heated in a coil E in the hotter part of the still C. The cracked oil passes through a release valve c to an expansion chamber G and dephlegmator H. Fuel oil collects in a receiver Q, and light oils in R. The liquid diphenyl is circulated by a pump S, make-up being supplied from a tank T. 'The shaft driving the pump S, which works at a high temperature, is preferably cooled by diphenyl circulated by a pump V at about 50‹ C. and at a pressure slightly greater than that of the main circulation. In an alternative form of apparatus, the whole of the heab for cracking the oil is supplied by indirect contact with the diphenyl. When cracking gas oil at 435‹ C. and at a pressure of 600 lbs. per sq. in., the diphenyl oxide is heated to 460‹ C. at a pressure of 450 lbs. per sq. in.

Title: Method of producing an oxide layer on metallic parts
IPC: C23C26/00
Filed: 1963-03-21
Abstract: In a method of producing an oxide layer on a metallic part to provide a surface to which ceramic will adhere, at least one metal layer (e.g. of Al, Be, Mg or Zn) is applied to a surface of the metallic part (e.g. of Cu, Ni, Fe, Cu alloys, Cr-Ni alloys or Ni alloys), the metal layer is substantially diffused into the metallic part by application of heat (e.g. at 800-1200 DEG C.), the metal layer is exposed to an oxidizing atmosphere at between 500 DEG C. and 1000 DEG C., and the oxidized metal layer is mechanically compressed (e.g. by rolling).  The ceramic may be sprayed on in molten form and may be an oxide which is the same as or different from that already produced on the metallic part.  MgO, Al2O3, ThO2, ZrO2 and BeO may be applied by the plasma-spray, flame-plating or plasma-plating methods.  The metal layer may be applied by melting a metal on the surface of the metallic part, dipping in a molten metal, cementation, vaporization, rubbing with metallic powders, spraying, galvanic plating or cathode vaporization. In the examples, (1) a Cu body is electrolytically coated with Be using a melt of NaF and 2BeO.5BeF2, (2) Cr and Ni steel parts are dipped in liquid Mg or the Mg is vaporized on to the steel, and (3) steel or Cu parts are sprayed with Al.  In all the examples the metal layer is diffused into the metallic parts, oxidation is in an air-oxygen mixture and the oxide layer produced by the oxidation is mechanically compressed before the application of a ceramic coating.ALSO:In a method of producing an oxide layer on a metallic part to provide a surface to which ceramic will adhere, at least one metal layer (e.g. of A1, Be, Mg or Zn) is applied to a surface of the metallic part (e.g. of Cu, Ni, Fe, Cu alloys, Cr-Ni alloys or Ni alloys), the metal layer is substantially diffused into the metallic part by application of heat (e.g. at 800-1200  DEG C.), the metal layer is exposed to an oxidizing atmosphere at between 500 DEG C. and 1000 DEG C., and the oxidized metal layer is mechanically compressed (e.g. by rolling).

Abstract: 806,291. Amplitude modulating apparatus. MARCONI INSTRUMENTS Ltd. Dec. 20, 1956 [April 16, 1956], No. 11459/56. Class 40 (5). A combined amplitude modulator and variable attenuator (for a signal generator) comprises a waveguide-beyond-cut-off attenuator having a waveguide 1 and slidably adjustable head 2. The waveguide is coupled to an unmodulated oscillator 4 by a launching coil 5. The head 2 carries both a pick-up coil 7 connected to an output lead 9, and an absorption coil 10. The two coils are tightly coupled. The coil 10 forms a closed loop with a crystal diode 11 and a R.F. by-pass capacitor 12. The diode 11 is biased by a fixed source 14 in series with a source of modulating signals 13, so that the diode conducts during the periods when the bias and the modulating signals are additive. When the diode 11 conducts, the power absorbed reduces the amplitude of the signals in the pick-up coil 7.
