Title: Improvements in or relating to power-transmission belts
IPC: F16G1/14
Filed: 1938-04-07
Abstract: 513,593. Driving belts of cellulose derivatives or other plastic materials. WILLIAMS, W. P. (Schering Akt.-Ges.) April 7, 19 38, No. 10732. Drawings to Specification. [Classes 2 (ii) and 2 (iii)] Endless power transmission belts, either seamless or having an autogenous joint, and having no stiffening support, are made from an elastic film-forming organic artificial material of low ductility and high tensile strength. Suitable film-forming materials are polymerization products derived from vinyl alcohol, vinyl chloride, vinyl esters, vinyl carbazole, acrylic acid esters or styrene, cellulose ethers such as benzyl cellulose, and cellulose esters such as cellulose triformate or cellulose triacetate. Suitable softeners such as aliphatic phosphoric acid esters may be incorporated in the film-forming composition. The autogenous joints may be made with the aid of swelling agents or solvents, or, in the case of thermoplastic materials, by heating the ends under pressure. Seamless belts may be made by casting the film-forming composition as on rotating cylinders, on endless bands, or on the inside surface of rotating drums, the casting being effected in the latter case by centrifugal force. In examples, endless belts are made from a composition of cellulose triacetate, ethyl alcohol,. methylene chloride, plasticizer and dye.

Filed: 1968-03-07
Abstract: 1,219,835. Defrosting. DUNHAM-BUSH Inc. 7 March, 1968 [10 March, 1967], No. 11239/68. Heading F4H. During defrosting of a compression-type refrigeration system, hot gas from the compressor discharge line 4 is supplied directly to the suction line 6, as well as to the inlet of the evaporator 20, to prevent the suction pressure from becoming too low and to evaporate liquid refrigerant entering the suction line from the evaporator. The hot-gas line 24, which is in heat exchange with a drain pan 40, extends to a point 25 in the evaporator inlet line 12 and has a branch 26 communicating with the suction line. A pre-set valve 28 in line 26 determines the relative quantities of hot gas flowing to the evaporator and suction line, and line 24 includes a solenoid valve 27 and a check-valve 30. Defrosting is initiated by the timer of a control unit 42, which closes a valve 16 upstream of the thermostatic expansion valve 18. The compressor continues to run until it is stopped by a low-pressure control or by means responsive to the evaporator outlet temperature or by a timer and the control unit then opens valve 27 and stops the evaporator fan 22. The compressor re-starts and remains energized since the flow through line 26 is sufficient to prevent operation of the compressor low-pressure control. Defrosting is terminated by control unit 42 when the evaporator temperature rises to a predetermined value subject to an over-riding control by the timer.

Title: Discharge of solid by-products separated from chlorination gases
Inventor: GROVES JAMES DENNIS
IPC: C22B1/08
Filed: 1957-04-09
Abstract: <PICT:0875156/III/1> <PICT:0875156/III/2> Ferric chloride impurity, deposited as a solid from titanium tetrachloride chlorination gases obtained from iron-bearing titaniferous materials, is absorbed in a melt made up of ferric chloride and another normally solid salt non-reactive therewith, the melt being maintained above the dew point of titanium tetrachloride and below the melting point of ferric chloride and generally in the range of 180-300 DEG C.  The salt making up the melt is preferably sodium chloride and this may constitute from 4-28% by weight of the melt.  The melt may be diluted in operation with further sodium chloride; alternatively it may be continuously or intermittently removed for regeneration.  The initial cooling of the chlorination gases may be effected with a cold liquid such as titanium tetrachloride, by recirculation of cool inert gases or by introduction of a solid such as ferric chloride which volatilizes under the operating conditions.  The process of Specification 806,052 may be used.  It is preferred to allow a small stream of chlorination gases from which the solid ferric chloride is separated, to pass over the top of the melt to prevent diffusion of ferric chloride back to the separator.  Alternatively an inert gas may be employed for purging the space above the melt. If ferrous chloride is present in the melt it is preferred to introduce a stream of chlorine into the body of the melt to convert it to ferric chloride.  According to examples (1) hot gases from the chlorination of ilmenite were chilled to 350 DEG C., ash was removed and gases then cooled to 170 DEG C. whereupon the iron chloride precipitated in a separator 1 as shown in Fig. 1.  A melt 4 containing 26% by weight of sodium chloride was maintained at 250-280 DEG C., and a minor amount of the chlorination gases were sucked down from the separator 1 over the top of the melt and out through outlet 13.  The melt was discharged through valve 11.  (2) An apparatus as shown in Fig. 2 was employed whereby the deposited solid chlorides from a separator 1 passed through a bifurcated duct 15 into one or the other of vessels 16 and 17 containing a ferric chloride/sodium chloride melt which became progressively enriched in ferric chloride.  The solid stream was then diverted to chamber 17 and chamber 16 heated to boil off the ferric chloride and regenerate the melt.  Specification 762,583 also is referred to.
