Title: Improvements in and relating to the preparation of derivatives of cholesterol
Filed: 1946-03-25
Abstract: 7-Halogeno derivatives of cholesteryl esters are obtained by reacting a 3-ester of cholesterol, i.e. a carboxylic acid ester in an inert solvent, e.g. 60-80 DEG  C. petrol, carbon tetrachloride, benzene and cyclohexane with a halogenator of the formula R.CO.NH.X, where X is bromine or chlorine and R is phenyl or substituted phenyl, e.g. the N-bromo-derivative of benzamide, m - nitrobenzamide, p - nitrobenzamide and p-methoxybenzamide.  The ester, solvent and halogenator must be such as will not react with the halogenated steroid.  The resulting 7-halogeno compound may be dehydrohalogenated, e.g. by methods described in Specification 574,432, to the 7-dehydro compound with or without hydrolysis of the ester group.  In examples: (1) cholesteryl acetate is treated with N-bromobenzamide in petroleum ether and after heating with diethylaniline and hydrolysing, 7-dehydrocholesterol is obtained; (2) to (8) as in (1) using as halogenators, N-bromo - m - nitrobenzamide, N - bromo - p - benzamide and N-bromo-3 : 5-dinitrobenzamide.

Abstract: 545,074. Electric heating elements. BRITISH THOMSON-HOUSTON CO., Ltd. July 21, 1941, No. 9196. Convention date, July 20, 1940. [Class 39 (iii)] Electric heating elements of the kind in which a resistance wire is embedded in powdered refractory material in a tubular sheath as described in Specifications 144,767 and 198,932, [both in Class 39 (iii)], are loaded with the insulating material while the sheath is rotated and intermittent blows imparted to it. The sheaths 11, containing the resistance held in a central position by temporary end caps, are arranged in upright positions'in a frame 15 and are provided with rotatably mounted heads 30, each having a hollow shaft 31 provided with ball bearings. The shaft is surmounted by a hopper 90 containing the powdered insulation. The sheath 11 is supported at intervals by transverse beams 43 carrying plates 47 with recesses in which the sheath is held by pivoted plates 49. The heads 30 are rotated as the sheaths are filled, by an electric motor 61 through toothed gearing 86 at about 20-25 revs. per minute. Blows are applied to the sheath at intervals along its length by vibrating hammers 101 pivoted at 102 and having springs 106 secured to the hammer and to a pin 112 on a plate 113 which is reciprocated so that the spring axis passes across the pivot 102 and a snap-acting blow is imparted by the hammer. Movement of the plate 113 is effected by an eccentric. device carried by the shaft 118 which is driven by the motor. The combined rotation and vibration of the sheaths retains the conductor in a central position and compacts the insulation. When filled, the sheaths are withdrawn and their diameter reduced by swaging. The ends of the sheaths are then severed to remove the portions which secure the temporary end caps.

Title: Improvements relating to the production, mixing, blending or refining of food products containing fats
IPC: A23G1/10
Filed: 1922-04-04
Abstract: 200,176. Spensley, J. W., and Chemical Engineering Co. (Manchester), Ltd. April 4, 1922. Addition to 186,462. Cocoa preparations.-Food products containing fats, such as margarine, cocoa butter, and edible fats generally, chocolate, and baking-preparations containing fats together with flour and other ingredients are uniformly mixed or refined by passage through a high-speed centrifugal pinned disc mill having a stationary pinned disc and rotating pinned disc the pins on the one disc intercalating in concentric rings with the pins upon the other, while substantially the whole circumference of the mill is open for the discharge of the treated materials by centrifugal action, an annular discharge receiving channel being provided around the mill. Preferably the mill employed is of the kind described in the parent Specification. The discharge outlet is surrounded by an annular casing or bin 5, Fig. 1, around which passed a scraper 6 for discharging the products through a shoot (not shown) that leads to the bottom of a removal elevator 9, power from the driving-shaft 10 passing to the scraper through pulleys 11, 12, belt 13, worm-shaft 14 and wom-wheel 16. A feed hopper 19 communicates with the interior of the mill through a tubular inlet 20 passing through the interior of a revoluble sleeve 17 connecting the worm-wheel with the scraper, and into a central aperture of the cover 18 over the mill. In the top of the casing an opening 21 communicates with a dust collecting balloon 22, and a steam jacket 23 admits of the contents being kept hot. The particular manner is set forth in which the mill is to be used with or without heat, with one or with several different fats at the same time, with repeated circulation of the materials by means of a pump, and in the specific manufacture of chocolate so as to perform the whole of the process within one or a series of the pinned disc mills and without employment of melangeurs, refiners, and conches. Other applications indicated with directions are to a modified process for chocolate without heat and to admixture of fats and flours to produce baking powder, or of oils with flour. Heating coils may replace the jackets. The peripheral speed of the pinned disc may attain to 20,000 feet per minute, at which even solid or semi-solid fatty matter is forced through the machine without any difficulty when fed in at the centre. Reference has been directed by the Comptroller to Specification 186,462.

Title: Improvements in and relating to electric clock mechanisms
IPC: G04C13/02
Filed: 1943-06-17
Abstract: 566,831. Clocks. TELEPHONE MANUFACTURING CO., Ltd., SMITH, S. J., and TERRY, R. ST. G. June 17, 1943, No. 9740. [Class 139] Pendulum operated and controlled mechanism of the kind in which a free pendulum (not shown) receives energizing impulses from a falling gravity arm at equal intervals of time, the release of the gravity arm being controlled by an attendant pendulum 1 which may form part of a master clock, is characterised in that a synchronizing magnet 10 receiving impulses from the free pendulum and adapted to apply synchronizing impulses to the attendant pendulum 1 is adapted to operate a rocking lever 2 which carries insulated spring contact members 3, 4, whose relative opening and closing is adapted to be controlled by a member 6 carried by the attendant pendulum, when they are brought into a predetermined position by movement of the lever 2 brought about by energization of the magnet 10. In the manner described in Specification 545,910, the free pendulum periodically closes contacts 13 for an instant to energize the magnet 10 which pulls the lever 2 down into the position shown, whereby one or other of two pallets 7<1>, 7<11> contacts a spring 8 on the attendant lever if it has departed from synchronism with the free pendulum. At the same time, a roller 5 on spring contact 3 engages the member 6 and the contacts 3, 4 close to lock in the magnet 10 until such time as the attendant pendulum has swung to a position where the member 6 frees the roller 5. The contacts 3, 4 then open, magnet 10 de-energizes and the lever 2 rises to inoperative position. By this means, the greater the variation from synchronism the longer is the magnet 10 energized and the greater is the correcting impulse.
