Title: Process for the production of pentafluoroethane
IPC: C07C17/21
Filed: 1961-03-20
Abstract: Chromium oxide catalysts for use in the preparation of pentofluoroethane are prepared as follows:-  (a) by precipitating hydrous chromium oxide from an aqueous solution of a chromium salt (e.g. chloride or nitrate) with ammonium hydroxide, and drying the precipitate as granules or cubes, (b) by mixing anhydrous chromic chloride with the hydrous chromium oxide of (a), and pelleting the mixture; (c) by reacting ammonium hydroxide with an aqueous solution of chromic chloride and aluminium chloride, and drying and shaping the precipitate formed; (d) by impregnating alumina with an aqueous solution of chromium trioxide, and then drying the material and reducing it in hydrogen; and (e) by heating the hydrous chromium oxide of (a) above in nitrogen and then in hydrogen chloride gas.ALSO:Pentafluoroethane is obtained by contacting a vapour phase mixture, comprising hydrogen fluoride and a perhaloethylene, with a chromium oxide catalyst at 200 DEG C. to 550 DEG C.  The perhaloethylene may be tetrachloroethylene, 1,1-dichloro-2,2-difluoroethylene or chlorotrifluoroethylene.  The catalyst may be hydrous chromium oxide in the form of granules, cubes or pellets, and may be mixed with chromium chloride or alumina, or chromium oxide may be employed on an alumina support.  The vapour mixture is passed over the catalyst in a reactor, the product is passed through a water scrubber, dried and condensed, and the components of the product separated by distillation.  Partially fluorinated compounds, e.g. chlorotetrafluoroethane, dichlorotrifluoroethane, chloropentafluoroethane, dichlorotetrafluoroethane, trichlorodifluoroethane and tetrachlorofluoroethane, are also obtained and may be recovered or may be recycled to the feed mixture.  When starting with tetrachloroethylene, 1 to 10 moles of hydrogen fluoride per mole of tetrachloroethylene may be employed. Examples are given.

Title: Controller for magnetic powder clutch for vehicle
Inventor: SAKAKIYAMA RIYUUZOU
IPC: B60W10/10
Filed: 1980-01-10
Abstract: PURPOSE: To provide optimum clutch torque characteristics by a method wherein a clutch current at the time of clutch engagement after completion of a speed change is maintained at a specified value.  
     CONSTITUTION: The switching of a transistor 13 is controlled by a signal P, and a coil 14 for the magnetic powder clutch is fed with a current. The clutch current is  not allowed to flow in the coil 14 during a speed-change operation, thereby enabling  the operation. During when the clutch is engaged, a current fed through intermittent on-off operations of the transistor 13 flows in the coil 14. In this case, the current is smoothed by a rectifying circuit 15 and a current of about 1/3W2/3 of a rated current is allowed to flow, establishing a semiclutched condition. After completion of the clutch engagement, the transistor 13 remains turned ON, so that the rated current flows in the coil 14 and a rated torque is transmitted as it is. Accordingly, the optimum clutch torque characteristics of the magnetic powder clutch proportional to the clutch current can be obtained.

Title: Method and apparatus for gas detection
Inventor: MITSUYOSHI TADAHIKO
IPC: G01N27/416
Filed: 1982-01-11
Abstract: PURPOSE:To perform highly reliable gas detection for CO detection having no malfunction by H2, by utilizing characteristics of oxidizing and reducing reactions of carbon  monoxide and gaseous hydrogen and discriminating two gases by the fact that an electrolytic current between electrodes is either of an oxidizing current or reducing current. CONSTITUTION:An action electrode 2 is formed on the one side of a gas-permeable  porous film 3 and a counter pole 5 and a reference electrode 6, are formed on the other  face of a porous film 4 and an electrolyte 7 is enclosed in an electrolytic cell 1. A  titled apparatus has such characteristics that an electrolytic current flows to the oxidizing side when carbon monoxide CO is brought into contact with the electrode 6 and the electrolytic current flows to the reducing side when H2 is brought into contact with the  electrode 6. The gas flowed from the outside is reached to the electrode 6 earlier than  the electrode 2 because a vent hole 11 of the film 4 is far large compared with a vent  hole 10 of the film 3. Accordingly, malfunction by the H2 is prevented by giving an  alarm buzzer depending on whether the electrolytic current flows to the oxidizing side  or the reducing side. Further, the activity reduction of the action electrode is prevented  and the stability of the apparatus is kept by adsorbing gases other than the H2 by  using a packing agent instead of the vent hole.
