Title: Method of and Apparatus for Drying, Conditioning and Regulating the Moisture Content of Hygroscopic Materials.
IPC: A24B3/04
Filed: 1918-05-21
Abstract: 121,080. Carrier, W. H., and Carrier Engineering Corporation. May 21, 1918. Chambers. - Relates to a method of and apparatus for drying, conditioning, and regulating the moisture-content of hygroscopic materials in a chamber by an induced circulation of air therethrough. The air is circulated in the chamber in a predetermined path having a mixing-zone and an exhaust zone within the chamber, these zones being so arranged that the greater portion of the air, when it reaches the exhaust zone, is again drawn into the mixing-zone by the introduction into the mixing- zone of a smaller quantity of conditioned air at a high velocity, the air from the exhaust zone becoming mixed with the charge of conditioned air, and the mixture then circulating through the chamber in the predetermined path. As shown, the material B, Figs. 1, 2, and 3, is hung on racks 18 in a room or chamber A so as to leave spaces 10, 11, 12 on three sides of the material, and conditioned air at a high velocity is delivered by a fan 17 through a duct 13 which extends along one side near the ceiling and is provided with nozzles 14 through which air is discharged horizontally into the space above the material. An air-exhaust duct 15 extends parallel with and just below the duct 13, and has openings 16 in its bottom adjacent the upper part of the side space 10. The air passes downwards in the space 12 at the back of the chamber, then through the passages 19 between the racks 18, and upwardly in the space 10 to mix again with incoming air in the space 11. Part of the air passes out from the space 10 through the duct 15. The moisturecontent and preferably the temperature of the air delivered into the chamber are varied for controlling the temperature and humidity, or both, in the chamber A. A hygrostat 24 located in the chamber or in the duct 15 controls a motor 25 which operates dampers controlling the connexion between the duct 15 and fan inlet 21, and dampers 23 controlling the fresh-air inlet. A steam jet discharging into the inlet 21 is operated by a diaphragm valve controlled by the hygrostat 24, and the steam or other heater 29 is regulated by a diaphragm valve controlled by a thermostat 31 placed in the chamber A or in the duct 15. In a modification, Fig. 5, the material B is arranged in the chamber A<1> in two portions separated by an intervening free space 10<a> in the middle of the chamber. The air is discharged from the supply nozzles 14<a> through open-ended tubes 32, and the exhaust duct 15<a> is arranged in the space 10<a> at the floor line.

Patent GB-908023-A (GB)
Title: Manufacture of halopropenes
IPC: C07C17/20
Filed: 1961-03-08
Abstract: Hexafluoropropene and 1,1-dichlorotetrafluoroprop-1-ene are prepared by disproportionating 1- or 3-chloropentafluoroprop-1-ene at a temperature of 300-450 DEG C. in the presence of heated anhydrous aluminium fluoride of crystallite size not greater than 500 Angstrom units radius made by the action of hydrogen fluoride on aluminium chloride.  The starting material may be purified by passage through heated activated carbon prior to its passage through the reactor. The emergent gases from the reactor may be condensed in a cold trap and separated by fractional distillation and may, prior to this condensation, be passed through a water scrubber to remove any acid gases formed. The recovered starting material may be recycled. 1,1-dichlorotetrafluoroprop-1-ene may be treated with chlorine and hydrogen fluoride in the presence of antimony pentachloride catalyst to give 1,1,2-trichloropentafluoropropane which, on treatment with zinc, yields 1-chloropentafluoroprop-1-ene which may be used as further starting material.  When 3-chloropentafluoroprop-1-ene is used as starting material some isomerisation occurs to give the 1-chloro-compound.  In examples: (1) 3-chloropentafluoroprop-1-ene is passed through a heated nickel tube containing activated carbon and then through another heated nickel tube containing the crystallite aluminium fluoride catalyst; the exit gases are condensed in a dry ice-acetone trap and distillation of the condensate yields hexafluoropropene, 1,1-dichlorotetrafluoroprop-1-ene and 1-chloropentafluoroprop-1-ene; (3) is similar to (1) but uses a higher temperature for the activated carbon treatment, causing isomerisation of the 3-chloropentafluoroprop-1-ene to the 1-chloro-compound.  Example (4) shows that under the conditions of Example (1) the starting material is not isomerised or disproportionated by activated charcoal.  Example (2) shows that the passage of 3-chloropentafluoroprop-1-ene over activated charcoal at higher temperatures than Example (4) gives 1-chloropentafluoroprop-1-ene together with small amounts of hexafluoropropene and 1,1-dichlorotetrafluoroprop-1-ene.  U.S.A. Specification 2,676,996 is referred to.

Title: Improvements in fluid pressure actuating systems
IPC: B60T13/16
Filed: 1944-05-11
Abstract: 595,188. Fluid - pressure - operated brakes. SCHNELL. S. May 11, 1944, No. 9013. [Class 103 (i)] [Also in Group XXVIII] The pressure produced by a manually operated hydraulic master cylinder causes a pump which supplies a brake or other operating motor, to be driven until the pressure in the motor reaches a value proportional to and greater than that produced by the master cylinder which is also directly connected to the brake or other operating motor. In one form, the pump comprises a number of units 29 driven by an electric motor 73 through a pulley 21, shaft 20, a roller 22 carried by the shaft and a swash-plate 28 mounted by a ball-and-socket 27 on a differential piston 26. Each pump unit comprises a delivery valve 38 and a piston 32 carrying an inlet valve 36, the supply being drawn from a reservoir 17 which is connected by pipe 19 to the reservoir 8 of the master cylinder 1. The master cylinder is connected by pipe 9 and passage 45 to the chamber 25 at the larger end of the piston 26 and the brake operating motors 12 are connected by pipe 10 and passage 56 to a chamber 42 intermediate the piston ends. A release valve device for the brake motors comprises a differential piston 46 normally held by a spring 50 on a seat 49 to close an axial passage 47 from the pipe 10. The switch 71 of the motor 73 is actuated by a solenoid 68 the circuit of which includes a switch 63 with a contact 59 normally held away from a fixed contact 60 against the action of a spring 66 by the piston 26 and a slidable plug 65. Operation of the master cylinder forces liquid therefrom by pipe 9 passage 45 openings in the piston 26 and past the seal 53 to chamber 42 thence to the brake cylinders 12 and at the same time the liquid pressure acting on the end of the piston moves it to close the contacts 59, 60 and to incline the swash-plate, the pump units 29 thus being operated to supply liquid to the cylinders 12 through passages 41 and chamber 42. When the pressure in this chamber acting on the differential area of the piston 26 is sufficient to overcome that acting in the chamber 25 on the piston end the piston and swash-plate are returned to the neutral position shown, the contacts 59, 60 also being opened to stop the motor 73. The release valve 46 is subject on opposite faces to the pressure in the master cylinder and the cylinders 12 respectively, and the ratio of the effective areas of these faces is the same as that of the areas of piston 26 so that when the master piston is returned to reduce the pressure in pipe 9 this valve moves to the left to reduce the pressure in the cylinders 12 by a proportional amount. In another form, the swash-plate pump is replaced by a rotary pump of the gear wheel type which delivers to an annular chamber formed on the piston 26 between the end seal 54 and an additional seal past which the liquid flows to the release valve 46 and pipe 10 the pump motor being controlled as in the device shown in Figs. 1, 2.
