Title: Aminopiperazine derivatives
IPC: C07D295/30
Filed: 1963-10-29
Abstract: The invention comprises aminopiperazine derivatives of the formula <F\1> wherein X may be a halogen or hydrogen atom, R is a hydrogen atom or methyl group, n is an integer from 1 to 6 and Z is a hydrogen atom or a phenyl, halophenyl, methylenedioxyphenyl, methoxy phenyl or hydroxyphenyl radical and the non-toxic addition salts thereof.  The halogen substituents may be fluorine, bromine, chlorine or iodine and suitable values of -(CnH2n)-Z are benzyl, phenethyl, a -methylphenethyl, phenyl-propyl, -butyl and -hexyl. The compounds may be prepared by refluxing a 1 - benzhydryl - 4 - aminopiperazine, a 1 - benzhydryl - 4 - [(alkyl or aralkyl)amino] - piperazine or a 1 - benzhydryl - 4 - methylaminopiperazine with the appropriate ester or acid halide to give the acyl hydrazide, of the formula I in which a -CH2-radical of the group R or -CnH2n-Z adjacent to the exocyclic nitrogen atom is replaced by a =C=O radical, and reducing the hydrazide by use of an alkali metal aluminium hydride in the presence of an inert solvent.  In an alternative method, a hydrazone of the formula <F\1> obtained by condensing a benzhydryl-4-aminopiperazine with an appropriate aldehyde or ketone, is reduced by the use of a hydric reducting agent; this method can be effected in one step by carrying out the aminopiperazine/ carbonyl compound condensation in the presence of molecular hydrogen and a hydrogenation catalyst. Examples describe the preparation of 1 - benzhydryl - 4 - methylaminopiperazine, 1 - benzhydryl - 4 - dimethylaminopiperazine, 1 - benzhydryl - 4 - (N - methylbenzylamino)piperazine, 1 - (4 - chlorobenzhydryl) - 4 - benzyl - aminopiperazine, 1 - benzhydryl - 4 - benzylaminopiperazine, 1 - benzhydryl - 4 - (4 - chlorobenzylamino)piperazine, 1 - (4 - chlorobenzhydryl) - 4 - (3,4 - methylenedioxybenzylamino)-piperazine, 1 - benzhydryl - 4 - isopropylaminopiperazine, 1 - benzhydryl - 4 - (a  - methylphenethylamino)piperazine, the 1 - benzhydryl derivatives of 4 - (4 - fluorobenzylamino)piperazine, 4 - (4 - iodobenzylamino)piperazine, 4 - (2 - chlorobenzylamino)piperazine and 4 - (4 - hydroxybenzylamino)piperazine.

Abstract: 1402466 Automatic control of temperature SIEMENS AG 26 Sept 1972 [27 Sept 1971] 44502/72 Heading G3R [Also in Division H1] In a method of operating a fuel cell, wherein electrolyte flows through the cell at a variable rate, an increase in the flow-rate is brought about as a consequence of an increase in the temperature of the electrolyte leaving the cell, and conversely a decrease in flow-rate is brought about by a decrease in electrolyte temperature. The arrangement is such that if the temperature of the electrolyte is below a predetermined minimum e.g. during the warm-up period then the electrolyte flow is substantially zero and this flow-rate gradually increases, Fig. 2 (not shown), as the electrolyte temperature increases. A thermistor, thermocouple or resistance thermometer 7 senses the highest electrolyte temperature, i.e. just after leaving the battery 2, and this is fed to a regulating unit 8 controlling the motor 6 operating the electrolyte pump 5. The system is stabilized at the optimum cell operating temperature. In an alternative arrangement the regulating unit 8 controls a throttle valve and the pump 5 is of the constant-speed type. The arrangement considerably reduces the warm-up time of the battery before it is ready for full operation.

Abstract: 1526927 Recovering vanadium from hydroconversion catalysts SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ BV 13 Oct 1975 [15 Oct 1974] 44604/74 Heading B1E [Also in Divisions Cl and C5] Vanadium and optionally nickel, is recovered from a catalyst which has become deactivated in a process in which a vanadiumcontaining hydrocarbon oil has been treated with hydrogen and the vanadium content of the catalyst has increased by at least 10 pbw per 100 pbw of catalyst carrier, the recovery of vanadium being achieved by extracting the deactivated catalyst with an aqueous solution of a mineral acid so as to reduce the vanadium content by at least 40% of the vanadium deposited during the catalytic treatment, the vanadium and possibly nickel are then isolated from the solution obtained. Mineral acid solutions exemplified are sulphuric: sulphurous and nitric acids. The catalysts may be any used conventionally in the treating of hydrocarbon oils with hydrogen, for example metal(s) with hydrogenating activity as a carrier, i.e. Ni, Co, Mo, W, V an alumina, silica on silica-alumina, or catalysts such as alumina or silica alone. These deactivated catalysts can be regenerated by removing as much of the Ni and V as is possible (if the catalyst required is to be free of these components) or by removing only enough of the Ni and V to obtain a catalyst containing desired quantities thereof. The regenerated catalyst can be used directly as such or after the addition of further amount of metals with hydrogenating activity.

Title: Improvements in or relating to an electrophotographic recording material
IPC: B22C9/00
Filed: 1960-12-29
Abstract: In the manufacture of an electrophotographic recording material (see Division H1), a sheet of paper or cellulose acetate is thinly spread with an aqueous solution of gum arabic, gelatin, or polyvinyl methyl ether and at least two kinds of fine particles each comprising filter dyes and colour-producing reagents, which undergo change on the passage of electric current, in a gelatin binder are sprinkled over the adhesive layer and the support or the coated surface is softly beaten to cause the gelatin particles to distribute themselves in a single layer on the adhesive, non-adherent particles thereafter being removed as by stronger beating action.  The resulting coated sheet may be compressed to reduce the gaps between the particles and the spaces remaining may be filled by impregnating the surface with paraffin wax dyed black.  In an alternative, the fine particles may be encapsulated in alakli-soluble cellulose acetate hydrogen phthalate, which may be admixed with an unreactive binder such as polyvinyl butyral, or an acid-insolubilized material such as a protein.  Reference is also made to coating by a beating technique a material bearing filter dyes and colour-changeable reagents coloured and made insoluble by oxidation with a layer of capsules containing an oxidizing agent such as cupric sulphate.

Title: Apparatus for transferring strip material
IPC: G11B15/22
Filed: 1970-09-21
Abstract: 1329996 Tape transports; brakes CANON KK 21 Sept 1970 [20 Sept 1969 26 Sept 1969] 44924/70 Heading G5R [Also in Division F2] Braking mechanism for a tape recorder comprises two brake wheels each rotatable with a respective reel in either direction, and brake shoes which can be brought into contact with both brake wheels to brake them, the shoes being arranged so that the brake wheels are braked only by brake shoes operating in an "escape direction" irrespective of the direction of rotation of the brake wheels. "Escape direction" is defined as that direction in which the (tangential) frictional force derived from the contact between shoe and wheel tends to decrease, rather than increase, the braking effect of the shoe on the wheel. As described, each wheel may have either one or two shoes associated with it, and in the latter case only one shoe is operative at any one time. As shown in Fig. 5, when brake wheel 23A is rotating as shown, and member 28A is moved to permit springs 21A, 22A, to act on arms 11A, 12A, respectively, in brake-applying direction, the brake torque developed moves arm 11A outward along pin 24A until little or no braking effect is exerted by shoe 13A, and moves arm 12A inwards and upwards, free of pin 25A, so shoe 14A is applied in the "escape" direction. (Link 18A may be stopped by pin 27A). In Fig. 7, by differently-shaped and orientated brake arms 111A, 112A, and appropriatelyplaced fixed pins 124A, 125A, it is shoe 113A which is applied and shoe 114A which is released during counter-clockwise rotation. In Fig. 10, arm 301A is urged leftwards by brake torque until holding lever 309A contacts pin 315A to cause application of the single shoe 302A in the "escape" direction. When the direction of wheel rotation is reversed, lever 301A is tilted in the opposite direction to cause brake application in the new "escape" direction. The greater spacing, from the wheel, of the righthand pivots and pins has the effect of providing that the braking force in the latter direction of rotation is less than that in the former. Fig. 15 shows a variant of Fig. 10. In Fig. 17, links and fixed pins are dispensed with: instead, pins 449 and 450 on brake arm 447 are accommodated in triangular slots of fixed mounting plates 451 and 452 respectively. In the embodiment of Fig. 5, where in the complete apparatus four springs such as 21A are provided, the strengths of the springs are so chosen that the wheel associated with the reel acting as supply reel for the time being has a greater braking force applied to it than the other wheel, to maintain the tape taut. Wire instead of tape may be employed.
