Title: Arrangement for tempering chocolate compositions
IPC: F25B15/00
Filed: 1963-11-08
Abstract: 995,982. Tempering chocolate. R. SOLLICH. Nov. 8, 1963, No. 44127/63. Addition to 995,981. Heading A2A. [Also in Division F4] In the chocolate tempering apparatus of the parent Specification the heating wire for adjusting the temperature in the tempering zone is dispensed with and an additional connection is established from the condenser part of the refrigerator to the vapourizer part and the correct quantity of fluid for compensating the excess cold in the tempering zone is supplied therethrough. Valve 22 in connecting duct 20 is controlled by switch thermometer 14 at the outlet of the tempering zone and opens if the tempering temperature drops. Hot gas flows into liquid duct 23 so that the liquified working medium of the refrigerator partly evaporates. The cooling output drops and the temperature of the chocolate composition in the tempering worm 12 rises. Water bath 24 serves as an insulating jacket and when refrigerator 7 is switched off serves to heat the tempering worm. The cooling output of the refrigerator is greater than that required for cooling to the tempering temperature.

Title: Improved fluorination process

IPC: C07B39/00
Filed: 1969-01-16
Abstract: 1281822 Fluorination process IMPERIAL SMELTING CORP (NSC) Ltd 9 Dec 1969 [16 Jan 1969 5 Sept 1969] 2592/69 and 44130/69 Heading C2C A continuous process for fluorinating organic compounds comprises simultaneously feeding fluorine gas and one or more organic compounds into a mechanically fluidized bed containing at least one solid inorganic metal fluoride capable of acting as a fluorinating agent by conversion to a lower valency fluoride. The exemplified fluoride is cobalt trifluoride, used in admixture with cobalt difluoride. The fluorine gas converts the difluoride to the trifluoride. The fluorine may be diluted with an inert gas or gases, for example nitrogen. The bed may contain one or more inert solids to act as heat carriers, and is fluidized by one or more impellers immersed therein. The product may be passed through a separator to remove cobalt fluoride dust and thereafter either (a) washed with water, preferably refrigerated, and the resulting liquid separated into aqueous hydrofluoric acid and the fluorination product, or (b) condensed and the condensate separated into anhydrous hydrofluoric acid and the fluorination product. In the latter case, the anhydrous hydrofluoric acid may be passed to an electrolytic cell to produce fluorine to be fed back to the reactor. Temperatures of 35- 450‹ C. are used if fully fluorinated products are required. Examples prepare (a) perfluoro-1- methyl-decalin from 1-methyl naphthalene, (b) perfluoro-1,3-dimethyl cyclohexane from mxylene, (c) perfluoro-n-hexane from n-hexane, and (d) per (chlorofluoro) cyclopentanes from hexachlorocyclopentadiene.

[Also in Divisions F1 and F3- F4] An air-cooled internal combustion engine 3 is transversely disposed in a compartment 1 at the front of a vehicle and in addition to being cooled by air entering opening 5 at the front of the vehicle it is also cooled by a blower connected to a duct 20 which forcibly directs air through passages 12 and 16 surrounding the cylinder body and cylinder head respectively of the engine. The passages 12 surrounding the cylinder body are subdivided by plates interconnecting the inner and outer walls and between which the air is deflected upwardly to be ejected at the top so that it is distributed about the outside of the cylinder head to assist in further cooling the head. The cylinder head passage is also subdivided by connecting walls and the passage also communicates with ducting 24 feeding warm air to the passenger compartment. The passages leading from the blower to the cylinder body and cylinder head are also provided with partitions to ensure an even distribution of the cooling air over the cylinders along the length of the engine.

Abstract: A substantially solventless siloxane encapsulating liquid is made by (A) forming a homogeneous mixture of (1) an organic solvent solution of a resinous copolymer of R3SiO0.5 and SiO2 units wherein R is a monovalent hydrocarbon (saturated or unsaturated) radical, the copolymer containing an average of from 0.3 to 0.8 R3SiO0.5 units per SiO2 unit, and (2) a liquid silanol-terminated diorganopolysiloxane having a viscosity of from 100 to 4000 cp. at 25 DEG  C. and in which the organic radicals are monovalent hydrocarbon radicals, and (B) heating the mixture at an elevated temperature to remove the organic solvent.  Solvents specified are aliphatic and aromatic mineral spirits, benzene, toluene, xylene and trichloroethylene.  Preferably siloxane (2) is used in amount of 1 to 10 pts.

Abstract: 1409279 Cinematography EASTMAN KODAK CO 6 Oct 1972 [6 Oct 1971] 46290/72 Heading G2E A strip take-up mechanism for use in a cine camera has two sliding members 4, 5, capable of movement relative to each other, operating so that when the strip (film) tension is too great film take-up is deferred until the tension is reduced. As shown eccentric 3 is driven by gear 2 via gear 1.  Sliding members 4, 5 have surfaces 6, 7 contacting the eccentric 3 to produce in them reciprocating motion in directions 20, 21. This motion causes tooth 13 to rotate gear 14 which carries a film 16 engaging a film reel (not shown). The members 4,5 are biased together by spring 12 and the relative movement of the members 4,5 is restricted to the directions 20, 21 by pins 9,11 in slots 8,10. If during filming, for example when the take-up reel is nearly full, the amount of film to be taken up is less than the reel movement produced by advancing the gear 14 by one tooth some relative movement of the members 4,5 will occur and the gear 14 will be advanced only by an amount equal to taking up the slack in the film. The parts 18, 19 may act as a meter of film usage.

In a circuit breaker of the kind having an arc control chamber 3 into which arc quenching fluid is injected, during opening of the contacts 5, 6, by means of a piston 7 coupled to the movable contact 6, the piston 7 is arranged to draw fluid from a supply chamber 1, through valve 19 and opening 18, into a reservoir during contact closing and to discharge it therefrom, through a second valve 20, into the chamber 3 during contact opening. The fluid flows through turbulator 4 into a cowl 11 from whence it is returned to chamber 1 through normally open valves 15, 16 which close in the event of excessive pressure to prevent damage to insulator column 10. The upper side of piston 7 is returned to the chamber 1 by way of passages 21, 22; the piston 7 is spaced from the walls of its cylinder 8 so as to allow escape of fluid around the piston if, due to excessive pressure in the chamber 3, the valve 20 should fail to open.
