Filed: 1943-04-20
Abstract: 563,156. Converting. GREVILLE, E. G., and GROVER, H. W. April 20, 1943, No. 6327. [Class 38 (ii)] [Also in Group XXXI] A D.C. voltage changer for producing a high unidirectional voltage for X-ray tubes, electromedical work or for an electrostatic precipitator for cleaning producer gas comprises a rotary commutator having segments 17 connected through slip-rings 13, 14 to a low voltage source such as a battery 7, and intermediate segments connected to resistances 19 so that alternating current of predetermined wave form is collected from the brushes 25, 26. Thus, by a step-up transformer 3, high tension A.C. is produced, which when rectified provides D.C. of a voltage approximating to the R.M.S. value of the voltage at the secondary terminals of the transformer. The rectifier may be of the thermionic valve type or, as shown, a rotary double disc full wave rectifier comprising conducting segments 33, 34 co-operating through air gaps with adjustable collectors 39 ... 42. The low voltage commutator and the high voltage rectifying discs are mounted on a common shaft driven by a motor supplied from the low voltage source which may be the battery of a vehicle running on producer gas cleaned by a precipitator energized by the high tension current produced.

Abstract: 744,909. Carbon paper. FRANCIS, F. G. Feb. 26, 1954 [March 11, 1953], No. 6743/53. Class 100 (4). A carbon paper has directly applied to one or both sides a supporting film of polythene which serves to prevent it curling during use. The polythene may include polyisobutylene or be compounded with white or coloured pigments; fillers to effect a rough surface may also be incorporated. The carbon paper may be produced by extruding a thin film from a press at a temperature of 150‹ C. directly on to one side of a moving paper web while applying pressure thereto, and thereafter applying a transfer composition to the paper web on one or the other side. The thickness of the film may be adjusted by control of the speed of the paper web or the rate of extrusion of the film. In an alternative arrangement, a film not more than 0.0005 inch thick may be applied first and the transfer composition applied at a temperature of 120- 200‹ C. so that the polythene and the transfer composition slightly intermingle.

Abstract: 829,034. Change-speed control. ELECTROHYDRAULICS Ltd. Feb. 21, 1958 [March 1, 1957], No. 6971/57. Class 80 (2). A selector rod 2 is slidden left or right from the neutral position shown to establish the ratio in a change-speed gear driven through a hydrodynamic torque converter, establishment of the ratio not selected then being prevented so long as an engine-driven pump (not shown) is driven at a relatively high speed and supplies fluid under pressure through a port 6 to act on a piston 8 against the bias of a spring 14, the pressure of the fluid sliding the piston within its bore so that a locking plunger 11 is projected into the space between a collar 3 on the selector rod and two collars on either side thereof, axial movement of the selector rod thereby being limited. The gearing may be a forward and reverse hydraulically-controlled planetary gear in a fork-lift truck, the engine of which drives the pump supplying the fluid under pressure. The piston 8 has a port 9 in its crown through which the oil flows freely to a venting passage 7 whence it returns to the pressure-fluid circuit and the pump. The spring 14 engages a threaded plug 13 screwed in-and-out of its bore to adjust the compression of the spring to a value such that, with the engine idling, the piston 8 is held in the left-hand position shown, so that the plunger 11 moves to the position shown and the selector rod 2 can then be slidden from one ratio position to the other. The collar 3 on the selector rod 2 is of such axial thickness that, with the plunger 11 projecting into the bore containing the selector rod, an established ratio can be disengaged by movement of the selector rod but further movement of the selector rod to establish the other ratio is prohibited.

The metal to metal contact between the member 12, wire 16 and casting 11 avoids the use of a separate bonding strip between the pipe and casting. In another arrangement, Fig. 4 (not shown), the wire coil is in two segments, each anchored to the ends of respective straps fitted over the pipe.

Abstract: Methyl manganese pentacarbonyl is prepared by reaction of sodium manganese pentacarbonyl (see Group III) and dimethyl sulphate in tetrahydrofuran solution (Ex. 3).  Cyclopentadienyl manganese tricarbonyl is prepared by reacting cyclopentadiene with a dispersion of sodium in tetrahydrofuran and adding the resulting solution to a solution of chloro manganese pentacarbonyl (see Group III) in tetrahydrofuran (Ex. 20).ALSO:Alkali metal manganese pentacarbonyls are prepared by reacting alkali metal with dimanganese decacarbonyl in the presence of an ether.  Dimanganese decacarbonyl dissolved in an ether, e.g. tetrahydrofuran, in proportion 1:100-20:100 preferably 9:100-20:100 is reacted with say a 4 preferably a 1 : 1-3 fold excess of alkali metal e.g. na, either as such, as a dispersion in an inert, organic liquid which is miscible with the ether present e.g. white mineral oil or the ether per se, or as an amalgam, at 10-100 DEG C. depending on the b.pt. of the ether.  Excess alkali metal is removed by settling or centrifugation followed by decantation to yield a clear solution of the product which is then stored under N2.  A or Xe to prevent oxidation.  The Specification also refers to the preparation of manganese pentacarbonyl hydride by contacting the alkali metal manganese pentacarbonyls in ether solution with an acid stronger than the resulting hydride e.g. a mineral acid or any suitable lower aliphatic carboxylic acid, at ambient temperature and in an inert atmosphere.  Acids specified include: Hcl, H2SO4, HNO3, H3 PO4, Ctt3. CO2H, C4 H11. CO2H, or C6H5. CO2H, strong oxidising acids at least, being used in the form of dilute aqueous solutions. Manganese pentacarbonyl hydride may be isolated from the reaction products by solvent extraction or decantation, pure material preferably being obtained by bubbling inert gas e.g. N2 or A, through the reaction products and condensing the resultant vapour with the aid of dry ice.  Ethers specified apart from tetrahydrofuran for either reaction include:- lower, saturated alkyl ethers containing at least 4, preferably 4-12 carbon atoms/molecule and having no active hydrogen or other active groups, e.g. ethyl-butyl, dibutyl, isobutyl-isopropyl, or methyl-neopentyl ether; ethers containing a plurality of -C-C C- linkages e.g. diethyl or dibutyl ethers of diethylene glycol; or most preferred, cyclic ethers e.g. derivatives of tetrahydrofuran, 1:3, 1 : 4 dioxane or derivatives thereof. Preparation of nitrosyl or methyl manganese pentacarbonyl (see Group IV(b)) or the complex HgClMn (CO)5 from alkali metal manganese pentacarbonyls and bromo, or chloro manganese pentacarbonyl from manganese pentacarbonyl hydride and cyclopentadienyl manganese tricarbonyl from chloro manganese pentacarbonyl and cyclopentadienyl sodium (see also Group IV(b)) are also referred to.
