Title: Process for recovering proteolytic enzymes from the pancreas of mammals
Inventor: FREDERIKSEN SVEND EMIL
IPC: C12N9/94
Filed: 1946-10-30
Abstract: Proteolytic enzymes are obtained by treating the residue resulting from the recovery of insulin from minced, fresh or well-preserved glands, treating the latter or an extract thereof at a suitable pH value with a quantity of alcohol or acetone sufficient to produce an alcohol or acetone concentration above 20 to 60 per cent and separating the liquid which is treated to extract the enzymes therefrom in the presence of a concentration of alcohol or acetone below 20 to 60 per cent.  The pH value during the enzyme extraction should range from about 1 to 7 and advantageously 1 to 4.  In examples: (1) pancreas glands are extracted with 80 per cent alcohol and the enzymes recovered from the filter residue by extraction with water; (2) as in (1) using acetone instead of alcohol; (3) pancreas glands are extracted with alcohol acidified with sulphuric acid and the enzymes recovered from the filter residue by extraction with urea solution; (4) as in (3), but extracting the enzymes with water at 100 DEG  C. Specification 613,030 is referred to.

Title: Improvements in cinematograph projectors
IPC: G11B15/34
Filed: 1957-10-16
Abstract: 859,497. Sound-film speed-controlling devices. PAPINI, G. Oct. 16, 1957 [Oct. 16, 1956], No. 32337/57. Class 40 (2). In an automatic speed compensating device for controlling the running of a film through the sound head of a cine projector, the flywheel effecting even speed of the film is driven both by the film itself and an auxiliary motor through a speed varying arrangement controlled by film tension regulating members. The film 2 after passing over a feed sprocket 4 and through the picture gate associated with lens 5, is drawn past erase and reproducing heads 6, 7 over a sprocket 8 associated with flywheel 9, and over a jockey pulley 12 by a sprocket 15. The flywheel is thus driven by the film, but is also driven by a rubber pulley 17 or 22 on an auxiliary motor 18 according to the position of a stirrup 21 which is set according to whether a film having 16 or 24 frames per second is being employed. As the drive sprocket 15 tends to speed up and increase tension, the jockey wheel 12 lifts and through a lever 23 lifts the auxiliary motor 18 so that the pulley 17 or 22 drives on a smaller diameter of the flywheel and slows it up accordingly. As the drive sprocket speed drops the reverse action takes place.

Filed: 1921-12-05
Abstract: 198,707. Lanchester, F. W., and Daimler Co., Ltd. Dec. 5, 1921. Brakes, arrangement and disposition of, and braking.-A brake of the Anternally expanding or coil type is applied with equal efficacy for either direction of rotation, by the frictional drag between the members of an electromagnet, one of which has a part which abuts one or other of the ends of the ring or coil while the other member is secured to the brake drum or a part rotating therewith. The member M<1>, M<2> of an electromagnet is axially slidable within the cylindrical extension K<2> of the brake cover K<1> and when energized engages the armature member N secured to the brake drum A whereupon a projection M<4> on the magnet member M<1> engages, according ta the direction of rotation of the drum, one or other of the ends of the brake ring L. The other end of the ring L comes against a stop K<3> on the extension K<2> and the ring is thus expanded into engagement with the drum A. The ring L may be made like a piston ring with or without a covering of friction material. Normally it grips the cylindrical part K<2> by its elasticity. A number of brake rings arranged to operate in series as described in Specification 133,156, [Class 103 (i), Brakes &c.], may be substituted for the single ring L. The brake is shown applied to the detachable steering wheel of a motor vehicle, the drum A being mounted on the hub member B and ths cover K<1> upon the stub axle member F<2>. It may however be applied also to the rear wheel brakes. The brakes on all the wheels may then be applied by a pedal controlling a rheostat, the propeller shaft or counter shaft brake being operated from a hand lever, or the front wheel brakes and countershaft brake may be electrically operated and the rear wheel brakes be controlled mechanically. The electric brakes may be arranged in parallel so that the failure of one will not affect the other, but when the axle pivot is eccentric to the road wheel centre the front wheel brakes may be in series so that the failure of onewill not tend to throw the car off the road.

Abstract: 847,674. Treating liquids by electrolysis. GREAVES & SONS Ltd., R. Oct. 20, 1958 [Oct. 19, 1957], No. 32696/57. Class 41 A method of producing chlorinated liquid from a liquid which contains a salt and which can be electrolysed to liberate chlorine, e.g. sea water, comprises passing the water continuously between electrodes 10, 15 which are suitably energised, so that chlorine is concentrated in the water flowing near one electrode, and drawing off the chlorinated water separately from water flowing near the other electrode. Electric connections may be arranged to enable the polarity of the electrodes to be reversed, the water outlets connections being likewise reversed. Water enters at 13 and flows between a casing 10, which here is the cathode, and a carbon anode 15 which are separated by a porous diaphragm 18. Outlets 42, 43 lead respectively from the catholyte and anolyte spaces. A scraper comprising three longitudinal bars, as 50b, 50c, connected by four rings, as 50d, 50f, 50g, is rotatable by a spindle 53 which engages two members 57, 58 which extend across the ring 50g. Alternatively, a longitudinally movable scraper may be provided. The rotatable scraper may be operated manually or mechanically. Two modifications are described in which no scraper is employed. Each comprises a cylindrical cathodic casing with coaxial inner anode and intermediate cylindrical diaphragm. In one case, sea water enters the casing by a radial inlet at one end, catholyte water leaving by a radial outlet at the other end and chlorinated anolyte water by an outlet disposed parallel to the axis of the casing. The other modification is similar, but the diaphragm extends the full length of the casing and a second inlet, for anolyte water, is axially disposed at the inlet end of the casing.

Abstract: 451,402. Washing granular materials. MEUNIER, F. J., 3, Villa Blaise Pascal, Neuilly-sur-Seine, France. Nov. 29, 1935, No. 33116. [Class 82 (ii)] Apparatus for the purification of coal &c. by the gravity concentration process includes one or more transverse partitions which may be movable and means for collecting separately the fractions which sink in the compartments formed by the partition or partitions, the collecting means comprising a single conveyer arranged at the bottom of the vessel below the partition or partitions and co-operating with discharge openings, each of which is positioned so that it removes the material which sinks in one of the compartments. Coal &c, is fed into heavy liquid in the vessel 1 by means of a hopper 9 with a feeding plate 11 worked by an eccentric 12. The coal 8 c. is directed along the vessel by a deflecting baffle 13 and the light material which floats is carried by a scraper conveyer 14 to a discharging bucket elevator 15 which dips into a quiescent zone of liquid in the vessel bounded by a grating 16. Near the bottom of the vessel one or more transverse partitions 21 tapering towards the upper edge are provided. The position of the partition 21 is adjustable by means of a hand wheel 26 on a threaded rod 25 passing through the partition. Below the partition is a screw conveyer 18 which co-operates with discharge openings 20, 19, the fraction sinking on the near side of the partition being discharged through the opening 20 and that sinking on the far side through the opening 19. The opening 20 preferably has an adjustable cross-section so that adjustments may be made to correspond with different positions of the partition. The openings lead by means of screw conveyers to the boots of elevators 23. The elevators 23 and the elevator 15 discharge the products on to screens 34 on which thev are rinsed and the liquid recovered and reconcentrated. Liquid is withdrawn from the quiescent zone bounded by the grating 16 and forced by a pump 28 into a transverse pipe 27 and longitudinal pipes 29, the pipes 27 and 29 having openings which produce horizontal and obliquely directed jets of liquid from the pipe 27 and upwardly and obliquely directed jets from the pipes 29. To prevent decrease in the density of the liquid owing to moisture carried in by the coal &c., liquid of greater density than that in the vessel is supplied from a tank 2 through a pipe 3 having a valve 4 controlled by a densimetric device 5.
