Abstract: 195,708. Lymburn, J. F. Dec. 28, 1921. No Patent granted (Sealing fee not paid). Vehicle and like lamps.-An incandescent lamp bulb is arranged with its filament extending actually or apparently forward or rearward of the focal point of the lamp and is provided with an internal screen which eliminates or subdues the rays which would normally be projected in a predetermined sector and leaves unmodified the rays in the remaining sectors of the emergent beam. Fig. 1 shows a motor-vehicle head-light in which the bulb filament is stepped in two planes so that its two parts 8, 8<1>, which extend respectively forward and rearward from the focal point, are separated by an opaque screen 6. Rays from the part 8<1> can only reach the upper part of the reflector and are reflected parallel to or towards the lamp axis, as at a, a<1>, b, b<1>, and rays from the part 8 can only reach the lower part of the parabolic reflector 7 so as to emerge with a downward divergence, as at c, c'. If the screen 6 is made translucent some upward illumination may be obtained, as shown by the dotted rays. These rays may be coloured selectively by the use of a coloured transmitting screen. In place of a stepped filament and flat-screen, the screen may be stepped and the filament linear, or, as shown in Fig. 3, a linear filament may be used with a tubular screen 12 having two semi-cylindrical parts cut away. Figs. 4 and 5 show a form in which the filament is disposed on a halfconical surface generated by a line from the focal point to the upper margin h of the reflector. The screen k is so placed as to cut off from the reflector all rays such as those shown at p, p<1> which would be reflected upwards.

Title: Improvements in or relating to the hydration of olefines
IPC: C07C29/04
Filed: 1931-12-22
Abstract: The hydration of olefines with the production of alcohols or ethers is effected by passing olefines and steam in contact with pyrosulphates which are stable under the reaction conditions, especially alkali pyrosulphates.  The temperature may be 100-350 DEG C. or more.  Pressure may be employed up to 25 atmospheres or more. The catalyst may be supported upon a carrier such as pumice, kieselguhr, carborundum or silica gel; or the gas mixture may be passed through a molten bath comprising the pyrosulphate, and the pyrosulphate may be in suspension or molten.  For the production of ethyl ether two or more volumes of ethylene to one of steam may be used, while for alcohol equal volumes of ethylene and steam are suitable.  Liquid water may be employed instead of steam.  In an example a mixture of 3 volumes of ethylene with 2 volumes of steam is preheated to 200 DEG  C. and passed through molten barium pyrosulphate at 300 DEG  C. under 20 atmospheres pressure.  The reaction vapours may be cooled under the same pressure to recover the alcohol.

Abstract: 847,228. Granulating metals. MARVALAUD Inc. Nov. 20, 1956, No. 35421/56. Class 82(2) [Also in Group XXII] A method of casting solid metal filaments or powder consists in projecting a stream of molten metal on to a rotating, smooth, concave mould chill surface 5, and controlling the speed of projection and speed of rotation so that the metal remains on the surface for less than one revolution. The metal may be tin, lead, cadmium, indium, zinc, bismuth, aluminium, magnesium, copper or other non-refractory metal or alloy. It is supplied to a transversely-adjustable nozzle 7 from a container 12, and is forced through the nozzle by pressure from a line 11. The size of the filament is controlled by the size of the nozzle 7, the speed of the mould-rotating motor 6 and the velocity and temperature of the molten metal at the nozzle. Movement of the nozzle during casting produces a filament of varying thickness. The chill block may be of brass, aluminium or steel, and the nozzle be of glass, steel, molybdenum, or silicon carbide. A number of spaced nozzles may be used to produce several filaments simultaneously. It is stated that the mould 4 may be a cylinder, cone or belt, and that external cooling means therefore may be provided.

Title: Improvements in or relating to drive mechanisms
IPC: G03B19/18
Filed: 1934-12-11
Abstract: 436,828. Brakes. RADIO CORPORATION OF AMERICA, 30, Rockefeller Plaza, New York, U.S.A. Dec. 11, 1934, No. 35583. Convention date, Dec. 29, 1933. [Class 103 (i)] [See also Groups XXVI and XXXI] A drive mechanism for delivering a constant torque from a variable driving torque comprises a member driven by the variable-torque producing device, a device tending to subject it to a counter torque equal to the variable torque, and a device acting thereon for producing a constant difference between the driving and counter torques. In the device shown a spring 10 drives a shaft 14 with a brake wheel 24 secured to it. A brake shoe 19 carried by a pivoted toggle arm 20 carries a pawl 22 which engages in a ratchet 23 on the spring barrel 11. The reaction of the spring on the barrel acting through the pawl 22 thus tends to move the brake shoe 19 to the right, and by the action of the inclined toggle arm 20 to apply it to the wheel 24 so that the frictional counter-torque of the shoe is equal to the driving torque and rotation of the shaft 14 is prevented. The constant difference between the driving and counter torques is produced by a spring 18, of adjustable constant tension attached to the brake 19 and tending to move it to the left, in opposition to the pawl 22. In these circumstances, if r is the radius of the brake wheel, P the pull of the spring 18, and F the force exerted on the brake block by the pawl 22, then, since the brake block remains in equilibrium, the tangential frictional force produced by it on the wheel is equal to F-P, and results in a counter-torque of (F-P)r. Since the driving torque of the spring 10 on the drum is equal to Fxr, the resultant torque, that is, the difference between the driving and counter-torques, = Fxr-(F-P)r = Pxr. The effective driving torque is therefore equal to the product of the tension of the spring 18 and the radius of the brake drum, and is independent of the variations in torque produced by the spring 10. Other devices are illustrated in which the driven shaft is operated through gearing of epicyclic form from a hand-crank, the planetary or idler gears being mounted on a pivoted carriage connected to the brake so as to produce on it a force equal at all times to the driving torque, which force is opposed by a constant-tension spring as in the mechanism above described.

Title: Dyed shaped articles of regenerated cellulose
IPC: D01F1/02
Filed: 1954-12-08
Abstract: Dyed shaped articles of regenerated cellulose such as filaments and films are made by mixing with viscose, at least one water-soluble, non-reduced sulphur dyestuff, having as such no affinity for cellulose, so that the dyestuff is reduced by the xanthogenate present in the viscose, extruding the mixture into a coagulating bath and exposing the shaped articles thus obtained to the air during the normal washing and drying processes, so that the reduced dyestuff contained in the articles is oxidized.  In an example, a paste containing 100 g. of Immedial carbon CBO is stirred at room temperature with 200 c.c. of water and 75 g. of sodium sulphite, the mass dried at 100 DEG  C. under reduced pressure and 102 c.c. of a 10 per cent aqueous solution of the thus solubilized dyestuff stirred for 1/2 hour at room temperature with 1000 g. of viscose containing 85 g. of cellulose. The viscose is then spun in the usual manner to form filaments which are subjected to the usual after-treatment with water, dilute aqueous caustic soda solution and dilute aqueous hydrochloric acid.  The filaments are then dried at 50-60 DEG  C. while exposed to the air and acquire a deep black colour. Specification 683,251 is referred to.
