Title: Process for the manufacture of cyclobutanones
IPC: C07J53/00
Filed: 1970-03-06
Abstract: 1308182 Cyclobutanones; steroids SCHERING AG 6 March 1970 [6 March 1969 18 July 1969] 10860/70 Headings C2C and C2U The preparation of an isomeric mixture of a cyclobutan-2<SP>1</SP>-one and a cyclobutan-3<SP>1</SP>-one of the formula (wherein R 1  and R 2  are each alkyl or cycloalkyl, or R 1  and R 2  together with the adjacent carbon atom represent a cycloalkyl or steroid group, and one of T and U is O and the other is H 2 ) is effected by reacting a tertiary α-ketone of the formula (wherein X is Cl or Br) with dimethylmethylene sulphonium oxide. The mixture may be separated into the individual components by standard methods such as chromatography. Novel steroid products have the formula wherein C 5  = C 6  is a single or double bond, V is H or CH 3 , and the A ring is one of the structures in which W is H, alkyl, tetrahydropyranyl or acyl, Z is H or CH 3  and Y is H 2 , H(OH), H(OR) or ethylenedioxy, R being alkyl or acyl. In these products an esterified OH group may be hydrolysed and a free OH group esterified. In the preparation of the cyclobutanones the reagent may be liberated from a trimethyl sulphoxonium salt in an aprotic solvent with an anhydrous base. Reactive keto groups in steroid starting materials must be protected, e.g. by ketalization. Named non-steroid products are 3,3 - dimethyl - cyclobutan - 1 - one, 2,2 - dimethyl - cyclobutan - 1 - one and spiro[3,5]nonan-2-one.  The novel steroids are pharmacologically active, e.g. they show a strong testicle and prostate inhibition in male rats and inhibit ovulation in female rats, and they may be made up into pharmaceutical compositions with suitable carriers.

Abstract: 560,760. Actuation of switches ; protective cut-out arrangements; dashpots. REYROLLE & CO., Ltd., A., ROBERTSON, A. T., and CRAWSHAW, 1. J. S. A. Aug. 12, 1942, No. 11263. [Class 38 (v)] [Also in Group XXXII] A dashpot arrangement suitable for circuitbreakers controlling polyphase circuits, comprises two liquid-containing chambers B, C inter-communicating through a restricted aperture A<1> having an adjustable needle A<2>, the chamber B having flexible diaphragms D operated by overload coils D<1> in each phase, and the chamber C, a diaphragm E controlled by adjustable spring F and acting on a switch E<3> through a lever E<2> which may have an adjustable fulcrum E<4> for time-setting. Further control of the operation may be provided by a spring flap-valve J with orifice J<2> arranged to provide quick return of the parts. Further diaphragms G are normally held retracted against spring-force H<1> by underload coils H. In Fig. 2, the diaphragms are connected to the plungers D<2> by light springs D<3> which return the plunger of a currentless phase, so producing relative movement between levers interconnecting the plungers, and operating contacts D<4>. By making the differential movement required to produce tripping greater than that of any diaphragm to produce overload tripping, it is ensured that overload tripping takes precedence over.single-phase tripping. The return member may consist of a body of gas. One or both chambers may contain a body of air which moves after the liquid in, so as to accelerate the finish of, the operating stroke, and before it in the return stroke. Alternatively the diaphragms may pull away from the passage A'. By making the displacement of E very large, overloads in all phases will be necessary to produce tripping.

Patent GB-220275-A (GB)
Title: Improvements in and relating to reclosing circuit breaker systems
IPC: H02H3/44
Filed: 1924-05-09
Abstract: 220,275. British Thomson-Houston Co., Ltd., (Assignees of Anderson, A. E.). Aug. 8,1928. [Convention date]. P7-otective arrangements.-Relates to improvements in an automatically-reclosing circuitbreaker system of the type described in Specification 220,276, in which a change of current is produced in the load circuit after the circuitbreaker has opened on overload and the reclosing is dependent upon the current rate of change being below a predetermined maximum. The system described employs circuit-breakers of the type set out in Specification 187,993 in which a generator 4 supplies a load circuit 1 connected by a circuit-breaker 3 of the above type to a load circuit 2 supplying a load 5. After the circuitbreaker 3 has opened on overload the time relay 11 is energized and completes the circuit of a contactor 10 which connects a resistance 9 between circuits 1 and 2 and if the consequent rate of flow of current is above, a predetermined maximum the energization of the transformer 8 with primary 12 in series with the, resistance 9 operates the relay 7 to prevent the circuit-breaker reclosing circuit from being completed. At the same time a second time relay 42 is energized, the function of which is to allow sufficient time for the operation of relay 7 before, the circuit-breaker reclosing circuit can be completed. If the rush of current in the resistance 9 is sufficiently great the relay 7 fed from the secondary 13 of transformer 8 operates, and so de-energizes relays 10, 11, 42, its core being held up by a pivoted catch 16. When relays 10, 11 are restored to their original positions the circuit of the coil 17 is completed so that nlay 7 is released and a further change of current is produced in the load circuit. If, however, relay 7 is not energized sufficiently, the relay 42 is permitted to complete its operation after which the relay 41 is energized, completing the circuit of the electromagnet 14 which closes the circuit-breaker. Two further relays 50, 51 may be provided for operation where the circuit-breaker connects two sections either of which may be energized and connected to the other when its electrical conditions are such that the relay 7 does not operate when the contactor 10 is closed. The relay 50 has an energizing winding 55 connected to the circuit 2 and an operating winding 56 between circuits 1 and 2, this relay being arranged in the manner described in Specification 207,549, so that an operating voltage for the reclosing gear is obtained from the section having the greater voltage when the circuitbreaker is open. Specification 125,279 also is referred to.
