Title: Unsaturated new sulphonamides
IPC: C07C311/02
Filed: 1961-05-25
Abstract: The invention comprises 3-substituted 1,4-endomethylene- D 5-cyclohexene- 2-sulphonamides of the general formula <FORM:0935860/IV(a)/1> (wherein R1 represents a C1-5 alkyl group or a phenyl group, and R2 represents a hydrogen atom, a C1-5 alkyl group or an acyl group) and their alkali metal salts, and pharmaceutical preparations containing a compound of the invention and an excipient. The sulphonamides are prepared by reacting a corresponding 3-substituted 1,4-endomethylene-D 5-cyclohexene-2-sulphonyl halide (e.g. the chloride) with H2NR2, and optionally acylating the product (when R2 represents a hydrogen atom), and/or converting the sulphonamide to an alkali metal salt, and/or separating the endo- and exo-isomers.  The sulphonyl halide starting materials are prepared by condensing cyclopentadiene with a ,b -unsaturated sulphonyl halides containing at least three carbon atoms (e.g. D 1-propenesulphonyl chloride or b -styrylsulphonyl chloride).  The compounds of the invention have an exciting effect on the central nervous system, and some of them are analeptics.  They may be administered enterally or parenterally in the form of pharmaceutical preparations (e.g. tablets, dragees, powders, ointments, creams, suppositories, solutions, suspensions and emulsions) containing them, with or without further active ingredients, in admixture or conjunction with an organic or inorganic excipient.

Title: Improvements in or relating to fuel injection systems
IPC: F02D41/30
Filed: 1961-05-26
Abstract: 976,340. Regulating I.C. engines. ROBERT BOSCH G.m.b.H. May 26, 1961 [May 27, 1960], No. 19039/61. Heading FIB. [Also in Division H3] In a fuel-injection system for an internalcombustion engine, a monostable circuit 30 controls the duration of conduction of transistors 91a, 91b (controlling the fuel-injectioncontrolling transistors 20, 21) in respective bi-stable circuits 26, 27, initiation of conduction being determined by pulses supplied by the windings 22, 23 of an A.C. generator coupled to the crankshaft. Considering the pulses from winding 22, positive half-cycles pass through diode 83a to switch NPN transistor 81a on and hence PNP transistor 91a, regeneration being applied through transformer winding 93a and R.C. network 85a, 86a. The pulse developed in winding 36 of the same transformer 37 is of a polarity to render transistor 33 conductive so that a feedback signal is applied through transformer 40 having an adjustable core to develop a signal across resistor 43 which is added to that appearing across potentiometer 45 and is applied through conductor 48, potentiometer 47 and conductor 46 to the base of transistor 31 thereby switching that transistor off and maintaining transistor 33 conductive through emmitter-follower 32. After a period determined by the characteristics of transformer 40 transistor 31 becomes conductive once more switching transistor 33 off so developing a large-amplitude negative pulse at its collector due to the primary winding of transformer 40 and so acting through diode 84a to switch transistor 81a and hence transistor 91a off. The length of the fuel-injection interval is determined by the movement of the core of the transformer 40 which is controlled in dependence upon the pressure at the inlet manifold. Further control is provided by voltages developed in circuits 55 and 64 and applied across potentiometer 45. Circuit 55 provides an acceleration-boost control the pulse developed in core 61 when the accelerator is depressed causing transistor 63 to conduct to charge capacitor 57 and thus apply a decaying control voltage to the base of transistor 31. Circuit 64 develops a voltage at low speeds to provide an idling control. A further voltage variable with speed is also applied directly from the potentiometer 47 to the base of transistor 31.

Filed: 1934-10-09
Abstract: 436,362. Controlling variable - speed gearing. FLURSCHEIM, C. H., Rushmoor, Fleet, Hampshire, and ASSOCIATED ELECTRICAL INDUSTRIES, Ltd., Crown House, Aldwych, London. Oct. 9, 1934, No. 19653 /35. Divided out of 432,981. [Class 80 (ii)] Relates to means for actuating by power a biassed control member 110a for change-speed gearing suitable for vehicles. Tnis control member or shaft 110a may actuate the executive control or bus-bar of a Wilson gear-box, not shown, and an engine clutch, if fitted. The shaft 110a is biassed by springs towards the right to the position shown witha crank 96 hard against a buffer 107<1>, The crank 96 is the crank of an electric servo-motor 95 which crank is connected by a link 97 to a crank 110 on the control shaft 110<a>. A further link 98 connects the crank 110 to a pedal lever 22 which can be used instead of the servo-motor. When the motor 95 is energized, the crank 96 is thrown sharply over to the left, pulling with it the control shaft 110a whereby the bus-bar is moved to release the brake bands in the gear-box. During this movement, return springs are stressed and a slot 101 allows the pedal 22 to remain unmoved. The crank 96 carries switch means 96a which break the motor circuit at the end of the crank stroke, whereupon the stressed springs immediately return the crank 96, link 97, crank 110, and control shaft 110a to the right, to the position shown. The crank 96 at the end of its outward stroke strikes a buffer 107, and the switch projection 96a strikes down a rod 102 which breaks the circuit at 104 between contacts 105. The return stroke is preferably retarded by a dashpot 108, which allows a pre-selected brake and the clutch to engage gradually. The electromotor 95 may be energized by the relay shown at 18 in Fig. 1 of Specification 432,981. According to the Provisional Specification, the crank of the servomotor might pass its dead centre on the outward stroke, and return to its first position by completing a revolution instead of by rocking backwards.
