Patent GB-802349-A (GB)
Title: New process for the production of a pure alkaloid
Filed: 1957-03-20
Abstract: Deserpidine is separated from its mixtures with reserpine, particularly those mixtures obtained by extraction of plant material of the Rauwolfia species, by treating the mixtures with a nitrosating reagent, especially sodium nitrite in acetic acid, and isolating deserpidine from the nitrosation products.  The alkaloid mixtures are preferably freed from reserpine to a considerable extent before nitrosation, e.g. by treatment with thiocyanic acid and separation of the less soluble reserpine salt.  The nitrosation is preferably carried out at about 20 DEG  C. to avoid nitrosating deserpidine itself.  In examples: (1) a mixture of reserpine and deserpidine (1:1) in methanol and acetic acid is treated with sodium nitrite, filtered from nitrosation products, deserpidine precipitated with ammonia and then purified by solution in chloroform-ether-petroleum ether, filtration, extraction of the filtrate with acetic acid and reprecipitation with ammonia; (2) as in (1) using a mixture of reserpine and deserpidine (1:3).

Abstract: 1,166,228. Seaming non-metallic sheet material. TELEPHONUND TELEGRAPHENFABRIKS-A.G. KAPSCH & SOHNE. 26 Feb., 1968 [7 March, 1967], No. 9228/68. Heading B5K. [Also in Division H1] A galvanic cell Z (or stack of cells) having contacts at each end is sealed in a tubular jacket of synthetic thermoplastic material by inserting the cell into the jacket so that a cell contact K touches external contact A1 embedded in the end wall S1 of the jacket; supporting the jacket around a marginal portion of wall S1; inserting into a terminal portion of the jacket an end wall S2 of synthetic thermoplastic material having an embedded external contact A2 which touches cell contact B; pressing wall S2 into the terminal portion so that transmitted pressure elastically arches wall S1 away from cell Z; welding wall S2 to the adjoining terminal portion; and releasing the pressure whereby the elastic return to shape of wall S 1 produces a substantial contact pressure between the cell contacts K, B and the external contacts A1, A2. As shown, contact K is the free end of a carbon electrode and contact B is the end of a zinc can; walls S1, S2 are of low pressure polythene and the tubular portion M of the jacket is of high pressure polythene. Pressure is applied by ram 5 which is locked in position at a predetermined pressure by wedges 7, 8. Welding mould 10 is lowered over the end of the cell to a position determined by wedge 7 acting as a stop for cross-beam 15. The mould is heated by contact with heating block 17, the lower part of the mould being continuously cooled so that only the end wall S2 and terminal portion of the jacket are heated and these are rapidly cooled after the raising of the heating block. Alternatively the mould may be heated directly by a highfrequency current or it may be made with a heat-conductive welding zone and an insulating lower zone and be heated and cooled by the application of hot and cold bodies alternately. The moving parts of the apparatus may be actuated by pneumatic cylinders 6, 9, 16, 21 or by cams.

Title: New carbonyl compounds and their precursors and the production thereof
Inventor: WEEDON BASIL CHARLES LEICESTER
IPC: C07D317/26
Filed: 1958-03-24
Abstract: The invention comprises compounds of formula <FORM:0920914/IV(a)/1> where Q is a carbonyl, hydroxymethylene, acyloxymethylene or ketalised (including cyclically ketalised) carbonyl group, R is alkyl, R5 is -OH, -OR6 or (except when Q is a carbonyl group) -R6, R6 being alkyl, R1 and R2 are alkyl and n is 1 or 2.  Compounds of formula I in which R5 is alkyl may be prepared by reacting an acid <FORM:0920914/IV(a)/2> or a halide thereof with a metal alkyl.  An acid of formula II may be obtained by hydrolysis of an ester of formula I where R5 = -OR6.  A carbonyl group Q of such an ester may be ketalised with a mono- or di-hydric alcohol or a cyclic ketalising agent, e.g. 2ethylenedioxybutane, in the presence of ptoluenesulphonic acid, or may be hydrogenated to a hydroxymethylene group which may then be acylated.  A keto ester of formula I wherein Q is carbonyl and R5 = -OR6 may be obtained by reacting an acid halide <FORM:0920914/IV(a)/3> where X is halogen with a metal alkyl. The acid halide III may be obtained by thionyl chloride on a monoester <FORM:0920914/IV(a)/4> obtainable by partial hydrolysis, e.g. with alcoholic KOH at normal temperatures, of the diester.  The semicarbazone of methyl 2,2-dimethyl5-ketoheptanoate is prepared in an example.  The Provisional Specification omits the limitation that R5 is not alkyl when Q is a carbonyl group in compounds of formula I.

Title: Improvements relating to liquid measuring and dispensing apparatus
IPC: B67D7/36
Filed: 1949-04-11
Abstract: 664,542. Dispensing petrol. WAYNE TANK AND PUMP CO., Ltd., and SMALE, N. E. May 2, 1950 [April 11, 1949], No. 9728/49. Class 116. Means for compensating for possible errors arising from hose dilation has associated with the pre-settable automatic cutoff mechanism an auxiliary valve controlled device which is responsive to the pressures in the delivery line on either side of the automatic cut-off valve incorporated in the mechanism and a compensating space' and in that the arrangement is such that upon an increase in pressure on the inlet side of the cut-off valve which obtains when the cut-off valve commences to close a volume of liquid equivalent to the volume of hose dilation that would normally occur at the particular delivery pressure is permitted to flow into the compensating space and is expelled therefrom to occasion a backwards flow through the flow meter when the delivery pump is put out of action. As shown in Fig. 2, the inlet pipe 201 from the cutoff valve leads to a chamber 22 of the auxiliary valve and an outlet pipe 211 leads from a chamber 23. A diaphragm 24 is mounted between plates 25 and 26 and a valve 32 is attached to the diaphragm and is associated with a spring 33. The intermediate cover plate 26 has an orifice 261 communicating with the chamber 22 which the valve normally closes. The orifice leads to a cylindrical chamber 28 having a piston 29, which is urged by a spring 30 towards the orifice, and a screw bolt 34. When the cut-off valve closes the difference in pressure between the inlet and outlet unseats the valve and liquid passes into the chamber 28 against the action of the piston. When the pump motor is shut off this liquid returns through the flow meter for effecting pressure relief and compensation. In the embodiment shown in Fig. 4 the cutoff valve 38 has the diaphragm 24 secured to a piston 36, and clamped by a cup 41 cooperating with the valve seating and orifice 261. The piston has two parts 291, 292, the part 292 has a projection 293 into a bore 282 in a sleeve associated with a cap 43 adapted to screw into the end of the cylinder. The chamber 23 communicates by passages 45, 46, 47 with the inlet side of the delivery line. The piston 36 responds to pressure through an aperture 401. The volume of the compensating space is a predetermined amount a bellows device may be used to vary the compensating space under pressure.

Abstract: 115,334. British Thomson - Houston Co., (General Electric Co.). July 10, 1917. Protective arrangements; electro-magnetic switches. -In distribution systems in which a number of generators 2 - - 5 supply current to common bus-bars such as 1 which supply the various feeders 10, 12 through oil-break, time-lag circuit-breakers 11, 13, the bus-bars are automatically and instantaneously sectionalized by means of switches 14, 15 in the event of a fault so that a reduced number of the parallel-connected generators supply current to the fault and operate the circuit breaker on the faulty feeder, whereby circuit-breakers of less capacity than the generator capacity of the station may be employed. The generator switches 6 and 9 are provided with auxiliary contacts 20, 21 which are bridged when the generator switches are closed thereby preparing the local tripping circuits of the section switches 14, 15, from the control bus-bars 27, 28 through a balanced-arm differential relay 22 with contacts 29, ready for tripping the section switches when, on the occurrence of a fault, the relay devices 18, 19 complete the local circuit by bridging the contacts 25, 26. A fault in one of the feeders 11 or 13 causes the instantaneous operation of the sectionalizing switch 14 or 15 so that current is fed to the fault only from the generator 2 or the generator 5. A dead short-circuit on one of the feeders 10 or 12 trips both switches 14 and 15, and generators 3 and 4 run idle. The generator switches 6 - - 9 serve in their open positions each to short-circuit one of the resistances 34 - - 37 in series with one, 32, of the differential windings of the relay 22. Each resistance is equal to one half the resistance 33 in the opposing differential winding 31. If, for some reason, one of the end generators, say generator 2, is not running, and its switch 6 is consequently open. the sectionalizing switch 15, only, is subject to automatic tripping on fault, the differential relay remaining closed since, although one 34 of the resistance sections is short-circuited, the current in the winding 31 is still greater than that in the opposing winding. If a fault occurs under these circumstances in one of the feeders 10, current is supplied to it by generators 3 and 4 only, while if it occurs on one of the feeders 12, current is supplied from generator 5 only. If two generators are out of action and consequently two sections of resistance are short-circuited, the relay is balanced and under its spring control it assumes the ' off ' position throwing the tripping means for the sectionalizing switches out of action since, under these circumstances, current can be supplied to a fault from two generators only.
