Abstract: 280,496. Tourne, C. Nov. 10, 1926, [Convention date]. Addition to 273,293, [Class 39 (i), Electric lamps, Arc &c.]. Repairing.-Burnt out or broken filaments are replaced without opening the bulb from a reserve continuous length of filament contained within the bulb. In the simplest construction of lamp bulb, the supply of filament is wound on a reel 15 carried by a rod 7 slidable in a sleeve 8 and the end 1 is drawn from the reel and secured between two clamps 2, 3 by which current is supplied to it. The clamp 2 is fixed and the clamp 3 is mounted on a slidable rod 7. To replace an active filament length the rod 7 is reciprocated to bring the end of the filament held by the clamp 3 into the grip of the clamp 2. A soft-iron bar 14 is screwthreaded on to the sleeve 8 and is coupled to the rod 7 by location between projections 12, 13 thereon, so that the reciprocation of the rod may be produced by rotation of the bar. This may be effected by rotating the bulb between the poles of an electromagnet. A device is described (Fig. 22, not shown) for rotating the bar from a distance by a flexible shaft coupled to toothed gearing within the cap of the bulb. Another device is described (Figs. 24-26, not shown), wherein an electric motor and switches are mounted in the cap of the bulb for effecting the operation automatically. Several filaments with independent renewal supplies may be mounted around the rod 7.

Title: Improvements relating to the separation of oxygen-containing organic compounds from aliphatic hydrocarbons by distillation
IPC: C07C7/06
Filed: 1950-07-03
Abstract: Aliphatic hydrocarbons are separated from mixtures containing aliphatic alcohols and other oxygen-containing organic compounds by adding water and an alcohol which contains fewer carbon atoms in the molecule than any alcohol in the mixture and which forms ternary azeotropes with the hydrocarbons and water, and then submitting the aqueous mixture to distillation to take the azeotropes overhead leaving the purified oxygen-containing compounds as residue.  The process is applicable to the purification of the alcohols obtained by catalytic hydrogenation of carbon monoxide, and by the catalytic addition of carbon monoxide and hydrogen to olefines; propanol being suitable as the added alcohol in such cases.  The mixture to be treated is preferably a fraction having a final boiling point not exceeding 250 DEG C. and containing only such compounds that the difference in the number of carbon atoms per molecule, is not greater than 6. The overhead-condensate separates into two layers.  The lower layer, which comprises an aqueous solution of the added alcohol, may be returned to the still.  The upper layer, which consists substantially of the hydrocarbons, may be distilled in a separate column for the recovery of any small quantity of added alcohol that it may contain.  In an example, a fraction boiling between 110 DEG and 160 DEG C., obtained by hydrogenation of carbon monoxide at a presure of 20 kg./sq. cm. using an iron catalyst, was mixed with 25 per cent. by volume of propanol containing 28 per cent. water; and the mixture was distilled.  Three fractions came over-at 81 DEG , 85 DEG , and 88 DEG  C.-which contained C8, C9 and C10 hydrocarbons, respectively.  The propanol/water azeotrope was then distilled off. From the residue remaining, C4, C5 and C6 alcohols were separated in a purified state by simple distillation.  In another example, a fraction boiling between 160 DEG  and 204 DEG  C., obtained by hydrogenation of carbon monoxide at 15 kg./sq. cm., was purified by azeotropic distillation with aqueous propanol to give a residue containing C7, C8 p  and C9 alcohols, which were recovered in a high state of purity by distillation in vacuo.

Title: Improvements in or relating to hydraulic systems for controlling double acting hydraulic motors
IPC: F15B11/12
Filed: 1951-07-16
Abstract: 692,838. Hydraulic machines. BENDIX AVIATION CORPORATION. July 16, 1951 [Sept. 25, 1950], No. 16863/51. Class 69(ii) A hydraulic system for controlling a doubleacting motor wherein the stroke of its piston in one direction is limited to a predetermined value comprises a control unit 10, having a valve member 25 actuated by a piston 27 slidable in a cylin-. der 23 communicating at one end through a passage 33 with a gear pump 34 connected by a shaft 36 to a gear motor 21. The motor 21 communicates through a passage 22 with the other end of the cylinder 23 and is driven by liquid exhausted from the left-hand end of the cylinder 12 of the doubleacting motor when the valve 25 is open. To move the piston 12a of the double-acting motor outwards, a control cock 13 is positioned to connect the unit 10 to a pressure liquid supply pump 16 and the right-hand end of the cylinder 12 to a tank 118. Pressure liquid, the pressure of which is insufficient to rotate either the pump 34 or the motor 21, is then supplied through non-return check valves 38, 40 to opposite ends of the cylinder 23. The valve 38 is lightly loaded opening first to cause rightward movement of the piston 27 and opening of the valve 25 until arrested by an adjustable stop member 29. Pressure then builds up in the cylinder 23 and the passage 33 when the more heavily loaded check valve 40 opens to pass pressure liquid through the now open valve 25 to the cylinder 12 and move the piston 12a outwards to the full extent of its stroke. To move the piston 12a inwards, the cock 13 is positioned to connect the unit 10 to the tank and the righthand end of the cylinder 12 to the pump 16. The check valves 38, 40 now close and liquid exhausted from the left of the piston 12a passes through the valve 25 to drive the motor 21 and with it the pump 34. The pump 34 then withdraws liquid from the cylinder 23 which permits movement of the valve 25 towards closure. On closure of the valve 25 the piston 12a stops, the stop position being determined by the stop 29 which determines the volume of liquid admitted to and hence withdrawn from the cylinder 23. The operator may if he desires limit the outward movement of the piston 12a by manipulation of the cock 13 which will also effect the final position of the piston on its inward stroke, e.g. assuming no adjustment is made to stop 29, the piston 12a will move farther to the left on its inward stroke. A spring 28 may be fitted to assist closure of the valve 25 and a non-return check valve 45 fitted in the outlet from the motor 21. In a modification, the outlet flow from the pump 34 instead of being led direct to the tank 118 through the cock 13 is led to the back of another piston connected to the valve 25 to assist its closure in lieu of the spring 28. A passage connects the opposite sides of this other piston and a check valve in the passage permits expulsion of liquid from the back thereof during its rightward movement.

The bushes are radially compressed by the insertion of a tube E which spreads the ends D' of the bushes into chamfers C' formed in holes C, C<SP>1</SP> in the flanges A<SP>1</SP>, B<SP>2</SP>. In a modification the bush D' is omitted and an integral pin projecting from the flange A<SP>1</SP> replaces the tube E. In a further modification the bush D<SP>1</SP> is made separate from the disc D and is traversed by a headed pin bolted to the flange A'. The gear wheel is made in one piece, e.g. by casting, and then broken to facilitate assembly to a shaft. The hub and rim are slotted at A<SP>2</SP> to form a weakened line for the break A' which is arranged to follow a path between two teeth in the rim. Lugs A', A<SP>5</SP> receive bolts which clamp the hub to a shaft, the two halves of the rim being attached each by a pair of rubber bushes to the flange A<SP>1</SP> and, the spacing disc D being formed in two portions. Specification 675,967 is referred to.
