Title: Improvements in apparatus for use in a gravity concentration process for the wet concentration of coal
IPC: B03B5/62
Filed: 1933-05-24
Abstract: 420,427. Concentrating coal. VOOYS, G. J. DE, Huckelhoven, Erkelenz, Germany. May 24, 1933, No. 28743/34. Divided out of and addition to 420,367 under which a Specification was laid open to inspection under Sect. 91 of the Acts, Dec. 5, 1933. [Class 82 (ii)] Apparatus for concentrating coal by the process described in the parent Specification, using a sludge of clay and barytes as the concentrating liquid, comprises a vessel 1 containing the concentrating liquid connected at the bottom to a bucket conveyer housing in which a conveyer 9 works to remove the gangue. A circulation is produced by withdrawing liquid both from the top of vessel 1 and from the conveyer housing and returning it to the vessel 1 through openings 11 so that an upward current is produced above the openings and a downward current below the openings. The floating coal is removed by means of a rake conveyer 5 which carries the coal along an extension 19 and then over a draining screen through which the liquid passes into a hopper 6 from which it is returned to the vessel 1. The rake conveyer is guided by strips 15 so that the rakes gradually dip more deeply into the liquid as they cross the bath. At the discharge point 17 the rakes are guided horizontally by the extension 19, and a grate 20, which may be made of wood and mounted so that it can swing or which may be made of rubber, is positioned in front of the outlet point to prevent the jamming together of the particles of coal. The vessel 1 is made with very steep walls and is joined at the bottom to the bucket conveyer housing in such a way that no particles can drop past the buckets or get fixed at the point where the vessel and the housing join. For this purpose the join is made as a sharp edge 23 and the buckets travel close to the opening 22. Above the edge 23 the conveyer housing is enlarged so that any particles of coal can float up. Liquid, together with any particles of coal, overflows at the point 24, the coal is removed by a rake or the like, and the liquid returned, together with liquid from an overflow in the vessel 1, to the openings 11.

IPC: C11C3/02
Filed: 1951-12-10
Abstract: Fatty acid glycerides suitable as ingredients of icing and chocolate coatings for bakery goods and candies in that they do not soften at summer temperatures but melt readily, without sensation of waxiness, in the mouth, are made by heating glycerol with an excess of fatty acids having 8-18 carbon atoms at sub-atmospheric pressure to cause esterification, e.g. heating to 450 DEG  F. at 25 in. of mercury below atmospheric pressure, maintaining the temperature of heating and the reduced pressure for a few hours, and then distilling off the free fatty acids by increasing the temperature, e.g. to 550 DEG  F., and reducing the pressure further, e.g. to 29 in. of mercury below atmospheric pressure.  The fatty acids employed are preferably those having 12-18 carbon atoms such as the fatty acids derived from coconut type oils, e.g. coconut oil and babassu oil, and consisting principally of lauric and myristic acids.  The ester from which the free fatty acid has been distilled may be refined and bleached, and may be hydrogenated.

Title: Improvements relating to fishing-reels
IPC: A01K89/06
Filed: 1952-11-20
Abstract: 718,681. Fishing-reels. STEENSEN, S. J. Nov. 20, 1952, No. 29348/52. Class 48 In a fishing-reel comprising a reel 7 mounted on a shaft 6 fixed to a bracket 5 secured to a rod 1, a friction disc 20 is rotatably mounted on the shaft and is in driving connection with a crank 27 the shaft 25 of which is arranged for limited axial movement to bring the friction disc into engagement with the reel. The friction disc is secured to a gear 22 rotatable on the shaft 6 and engaged with a gear 26 on the inner end of the crank shaft 25. When the crank shaft is pushed inwardly its gear 26 pushes the friction disc into contact with the reel and when the shaft is returned outwardly by a helical spring 30 its gear 26 abuts a flange 23 on the other gear 22 so that it carries this gear 22 and the friction disc with it. In a modification, Fig. 3, the spring 30 and shaft 25 are surrounded by a sleeve 39 which is held in contact with the bracket 5 by a blade spring 40 having a forked end slidable in a groove 41 in the sleeve. The end of the crank 27 is formed to engage with a cam surface formed on the sleeve 39 at an angle to the shaft 25 and when the crank 27 is turned the end rides along the cam surface so that the shaft 25 moves inwardly to engage the friction disc with the reel. At casting the shaft 6 is arranged parallel to the rod as in a stationary type reel but the reel is caused to rotate by initially passing the line around a finger 37 carried by the bracket 5 and disposed between the planes of the end surfaces of the reel. When the reel has reached a sufficient speed the line is freed from the finger so that it then unwinds over the free end of the reel. The latter continues to rotate thus minimizing twisting of the line. The finger may be rigid or made of springy material or it may consist of one end of a spring-loaded lever 37<SP>1</SP> journalled to the bracket, the other end extending to be operated by the fisherman's hand holding the rod. A cup-shaped member 15 is rotatably mounted independently of the reel on the outer end of the shaft 6 and has a flange 16 covering the front flange 8 of the reel. At winding in, the line is guided on to the reel by the fork-end 33 of a pivoted spring-loaded lever 31 rocked by the fisherman. The direction of the winding of the line on the reel may be reversed by placing a loop of the line around one of a series of tooth-like projections 10 formed on the rear flange 9 of the reel and rotating the reel in the reverse direction.

Abstract: 319,786. Telefunken Ges. fiir Drahtlose Telegraphie. Sept. 28, 1928, [Convention date]. Fading, preventing ; modulating systems and apparatus; selective signalling systems.-To prevent fading, the shunt branch of a transfer circuit between a high-frequency generator and the aerial is so influenced by low-frequency oscillations that a plurality of high-frequency oscillations of different frequencies but similar amplitude is simultaneously radiated. The transfer circuit II, Fig. 1, has a shunt a tuned to the oscillator frequency, for which it provides a short-circuit path, so that if the shunt is detuned at one or more low frequencies, only the corresponding side-band frequencies are transferred to the aerial. Detuning is effected either by varying the magnetization of the choke L, Fig. 2, from the low-frequency source N, or the capacity of the condenser C by a vibrating diaphragm. For telephony, circuit N may carry the microphone current, the carrier wave being added at the receiver end.
