Patent FR-1423739-A (FR)
IPC: C08F2/54
Filed: 1964-10-01
Granted: 1966-01-07
Abstract: Telomerized alcohols are obtained by irradiating with high energy ionizing radiation a flowing mixture of reactants in the vapour or liquid phase, the reactants comprising an alcohol having fewer carbons than the product alcohol and an olefin, the dose rate of the radiation being 1 to 40 megarads/hour and the radiation being applied for a period of 10 secs. to 10 mins.  The reaction in the vapour phase is suitably effected at approximately atmospheric pressure and at a temperature sufficient to maintain the vapour phase and the concentration of alcohol with respect to olefin is preferably in an overall molar range of 0.5:1 to 40:1. The starting alcohol may be a C1- 6 saturated aliphatic alcohol and is preferably an alcohol containing a tertiary hydrogen atom and the hydroxyl group on the same carbon atom; the starting olefin is preferably a C2- 6 1-olefin but it may contain up to 12 carbons and it may also be a diolefin. The high energy ionizing radiation may be ionizing particle radiation, e.g. accelerated electrons, nuclear particles including protons, fast neutrons, alpha and beta particles, deuterons and fission fragments, and ionizing electromagnetic radiation, e.g. gamma rays and X-rays.  The energy level at which the radiation is employed is suitably 1 kev. to 30 mev.  The reaction in the liquid phase is suitably effected at room temperature to 200 DEG  C. at a pressure which is approximately atmospheric and the concentration of alcohol with respect to olefin may be in a molar range of 15:1 to 500:1.  The starting alcohol may be a C1- 12 saturated aliphatic alcohol and is preferably an alcohol having a tertiary hydrogen atom and the hydroxyl group on the same carbon atom; the starting olefin and the radiation may be the same as that employed in the vapour phase reaction.  In the vapour phase reaction, energy transfer substances, e.g. rare gases or solids of high surface area may be employed.  In the examples, mixtures of isopropanol and ethylene are reacted together.

Title: Apparatus for removing dust from granular material
IPC: B01D50/00
Filed: 1952-01-14
Abstract: 693,418. Pneumatic separating; centrifugal separators. VOGEL W. Jan. 14, 1952. No. 1031/52. Classes 23 and 117. In apparatus for removing dust from granular material by sifting in an air current which traverses a sieve along which the material moves forward, the sieve is divided into zones which are traversed consecutively by the air current, and cyclone separators are provided for separating the dust from the air current between each pair of zones. As shown the material is fed from a hopper 1 to a sieve 2 which is vibrated to feed the material along it. The apparatus is divided into five zones traversed in succession by the air current, each zone comprising four sections which are traversed in parallel by the air current. Below and above each section are pyramidal pipes 3 and 4 respectively, which are connected by rubber sleeves 5 to the part of the housing which vibrates. Pipes 6, which are provided with suction valves 7, are fitted to' the bottom pipes 3 of the sieve zone at the exit end and are connected to a collecting bunker 10. The other pipes 3 are connected to cyclone separators 8 which are also connected through paddle wheels 9 to the bunker 10. The top pipes 4 are connected to cycline separators 11, each group of four separators being connected through an individual paddle wheel 12 to a common pipe 13 connected to the bunker 10 and provided with a worm conveyer. Each group of four separators 11 is connected to the suction pipe 16 of a fan 17, and the pressure pipes 18 of those fans which are connected on the suction side with the first to the fourt sieve zones lead into the lower cyclone separator of the immediately following sieve zone. The pressure pipe 19 of the last fan 17 supplies air to a dust-removing device not shown. The fans draw an air current through the sieve in opposite direction to the movement of the material being sifted, the coarse material falling through the sieve to be separated in the cyclone separators 8 or falling down the pipes 6 and the dust is carried away by the air current above the sieve having its coarser constituents removed by the cyclone separators 11. The fans 17 are so arranged that the throughput of the second to the fifth fan is a little greater than that of the immediately preceding fan to ensure that a sub-atmospheric pressure is maintained in the space above the sieve, and for this reason paddle wheels 20, 21 are provided at the entry and exit of the sieve. For wet material the pipes 3 and 4 may be provided with heating jackets supplied with hot water or steam preferably circulating in the same direction as the air current.

Patent GB-283735-A (GB)
Title: Improvements in dash-pots and equivalent devices
IPC: F16F9/24
Filed: 1927-01-14
Abstract: 283,735. English Electric Co., Ltd., and Deriaz, P. Jan. 14, 1927. Dashpots.-In apparatus in which movement is transmitted from a driving element 2 to a. driven element 3, the initial rapid displacement is effected by fluid pressure and the slow return to the normal position is controlled by valves or ports brought into action by the movement of the piston in the cylinder. The driving element 2 carries an arm 12 connected to a piston 6 disposed in a cylinder 7, the upper end of which is connected by passages 8 to the lower end of a cylinder 4 containing a dashpot piston 5 adapted to operate an arm 11 on the driven member 3. Return movement of the arm 11 is effected by a spring or by a positive connection to the piston 5. The annular space 14 above the piston 5 is connected to an independent source of fluid pressure through the passage 15 which also supplied pressure fluid to the groove 20 in the cylinder 4. The groove 21 is connected to an exhaust pipe 22. When the piston 6 is raised rapidly, the dashpot piston 5 is also raised rapidly by direct fluid pressure against the pressure in the annular space 14. Conversely, when the piston 6 is lowered rapidly, the piston 5 follows under the action of the pressure in the annular space 14. In either case return to the normal position in which the piston 5 is shown is effected slowly by fluid pressure. When the piston 5 is moved upwardly, the movement is checked and the slow return started when the central groove 17 in the piston communicates with the exhaust groove 21 in the cylinder, since the lower end of the cylinder is then connected to exhaust through the passage 16 in the piston and the groove 17. The downward movement is continued by the pressure in the annular space 14, but is checked by regulating the rate of escape of fluid below the piston 5. This escape takes place to the exhaust groove 21 through a restricted passage in the plug 24 and then through an annular groove 19 and its helical extension of diminishing depth so as to bring the piston slowly to rest in the central position. When the piston 5 is moved downwardly, the movement is similarly checked and the return movement started when the central groove 17 in the piston communicates with the pressure groove 20 in the cylinder, the annular and helical grooves 18 then being utilized. The piston 6 may be arranged in the lower part of the cylinder 4, the cylinder 7 being dispensed with.
