Filed: 1967-02-07
Abstract: 1,143,712. Telegraphy. SIEMENS A.G. 7 Feb., 1967 [8 Feb., 1966], No. 5759/67. Heading H4P. A circuit for detecting the clearing signal in a telegraph exchange system comprises a number of relays and a pulse generator ZTG as shown. If a clearing signal comes from a local subscriber, who is connected via subscriber circuit TS and the exchange to a distant subscriber on line FL, contact a goes to-TB. When the pulse generator applies a pulse on 201 relay F is energized and locks up, and the circuit of relay MZ is prepared 200 m.sec. later a pulse on 202 energizes MZ and the circuit of a relay M is prepared. 200 m.sec. later M is energized and its contact m2 releases the seizing relay C. Had the clearing signal originated from the distant subscriber the relays energized in succession would have been L, MZ, and M. If a signal of clearing signal polarity lasts less than 200 m.sec., relay F (or L) will be de-energized before relay MZ can be energized and so the seizing relay will not be cleared. Contacts mz 3 and f3 prevent relay A from receiving the stop polarity disconnect signal returned from the distant station.

Title: Improvements in and relating to the preparation of derivatives of cholesterol
IPC: C07J9/00
Filed: 1946-02-25
Abstract: Steroid substances rich in 7-halogencholesteryl esters suitable for conversion into 7-dehydro-derivatives are obtained by reacting a 3-carboxylic ester of cholesterol with a halogenator of the formula <FORM:0608482/IV(b)/1> where R1, R2 and R3 are lower alkyl groups and X is chlorine or bromine in an inert solvent, e.g. carbon tetrachloride.  Preferably equimolecular proportions of the cholesteryl ester and halogenator are used and the reaction is carried out at the boiling point of the solvent in the presence of an organic peroxide, e.g. benzoyl or acetyl peroxide.  Excluded from the scope of the present invention are esters, the acyloxy fragment of which contains any grouping which reacts either with the halogenator or with the halogenated cholesterol.  In examples: (1) a carbon tetrachloride solution of cholesteryl acetate is treated with tertbutyl hypochlorite in the pressure of benzoyl peroxide; (2) as in (1), using tert-butyl hypobromite. The products of the examples may if desired be dehydrohalogenated. Specification 574,432 is referred to.

Filed: 1923-03-01
Abstract: 216,584. Illingworth, S. R., and Illing- worth Carbonization Co., Ltd. March 1,1923. Moulding, fuel blocks; moulds.-Apparatus for the manufacture of briquettes comprises a plurality of superposed inclined chambers 10, in each of which is disposed a mould 17, means being provided for feeding the coal at the upper ends of the chambers and also for moving the moulds to allow of the discharge of the briquettes. The mould 17 is divided into compartments by transverse and longitudinal partitions, of which the longitudinal partitions 171 are the higher with the exception of the partition at the lower end, and an extension 172 is formed at the upper end of the mould. Cover plates 18 having projections 180 fitting into the compartments of the m6uld are carried by saddle pieces 19 which are maintained in position in the mould by guides 20 on the mould sides. Wedges 21 operated by a lever 210 are adapted to raise and lower the cover plates. The mould is supported by rollers 22 adapted to run on trackways 23, which being inclined cause the mould to be raised when moving down the chamber. In operation, the cover plates having been raised clear of the transverse partitions 170, coal is admitted through the feed valve to the compartments, and when the mould is full the cover plates are lowered so that the projections 180 rest on the surface of the coal. After heating, the hand wheel 24 is operated to cause the mould to move down the chamber on the trackway 23 until the plates 18 contact with the upper surface of the chamber and by means of the projections 180 expel the briquettes. At the lower end of each chamber a wheel 15, driven by means of a sprocket wheel, discharges the briquettes into a cooling chamber 16 having a discharge opening 160. The feeding arrangements comprise a hopper from which the coal is fed by means of main pipes 12 and branch pipes leading to the chambers. In a modification the moulds are mounted in frames carrying the trackway, the cover plates, and the crank levers for operating the wedges, this assemblage of moulds being charged outside the heating chamber. Specifications 164,104 and 186,085, [both in Class 55 (i), Coking &c.], are referred to.
