Abstract: 500,182. Catalytic agents. EVANS, W. E. (Ruhrchemie Akt.-Ges.) May 1, 1937, No. 8643. [A Specification was laid open to inspection under Sect. 91 of the Acts, Oct. 2, 1937.] [Class 1 (i)] In the preparation of catalysts suitable for benzine synthesis &c. by precipitating a coinpound of the iron group upon a carrier consist ing of kieselguhr, powdered asbestos, chromium oxide, or steatite, the carrier is previously heated to incandescence (i.e. above 1000‹ C.) to reduce the solubility of constituents soluble in the acid and alkaline reagents used in the preparation and regeneration of the catalyst. To obtain a fine distribution of the carrier material it may be mixed with finely divided combustible material such as wood-pulp before heating. An extraction with acid may follow the heating. As a further precaution against solution of constituents of the carrier the latter. may be added to the catalyst, solution only when the precipitation of the latter is almost completed. When the exhausted catalyst is dissolved off the carrier by means of acid and reprecipitated, any impurities which have also been dissolved may be removed by ,a preliminary precipitation followed by filtration.

Title: Composite ceramic-metal bodies
IPC: C04B37/02
Filed: 1955-03-30
Abstract: A method of hermetically bonding aluminium or magnesium to a ceramic, comprises applying to the ceramic a layer of zirconium or titanium or a mixture or alloy thereof, applying to the said layer a solder having a melting point higher than that of the metal to be bonded and casting the metal to be bonded to the metallized portion of the ceramic.  The term "ceramic" includes glass, porcelain, diamond, graphite and the like, and the solder may be silver or a silver-copper alloy.  The titanium &c. layer may be applied by placing a powdered metallic hydride on the ceramic member and dissociating it to leave a metallic layer. Alternatively a suspension of metallic hydride, e.g. 3-4 grams of metallic hydride with 1-2 drops of a cellulose nitrate lacquer and 2-3 ccs. of a solvent such as amyl acetate may be applied as by brushing, and the coated member heated to over 500 DEG C. in a vacuum or non-reactive atmosphere such as hydrogen, helium or argon. The solder layer may be melted over the first metal layer during the formation of the latter.  The metal to be bonded is then placed in a carbon retaining mould placed about the coated ceramic part and the assembly heated, to a temperature, e.g. 660-750 DEG C. for aluminium, in a vacuum or inert atmosphere, until melting is complete and then cooled in a vacuum or inert atmosphere. U.S.A. Specification 2,570,248 is referred to.

Title: Improvements in or relating to tension control in winding apparatus
Inventor: DEFONTENAY PAUL
IPC: F16H61/02
Filed: 1968-02-27
Abstract: 1,221,956. Tension control in winding. P. DEFONTENAY. 27 Feb., 1968 ['15 March, 1967], No. 9330/68. Heading D1D [Also in Divisions B8 and F2] In apparatus for winding material into or off a spindle A, driven by a motor M 1  and having a torque control device PC which maintains the tension in the material at a predetermined value, the torque control member which normally acts as a brake and is driven by the motor about a rotatable axis against a braking torque is also capable of acting as a motor to augment the driving torque exerted on the spindle when driven in an opposite rotational sense by a power source PA. The motor M 1 , the spindle A 1 , and the member PC are connected to respective elements of a differential gean D. The power source Pa is driven by an auxiliary motor M 2  which is automatically brought into operation when motor M 1  does not supply sufficient power to maintain the desired tension T. The output of pump Pa exceeds the maximum input of pump PC when the latter acts as a motor so that some excess fluid passes through regulator valve RC which is adjustable for allowing the tension T to be varied. An arrangement for the automatic control of pump PC is shown in Figure 12. Pump PC rotates around shaft 2 by pinions 41 meshing with pinions 42 keyed to the shaft. The pump acts as a brake when the various parts rotate as shown by the arrows, fluid being pumped from reservoir 18 through ducts 43, 44 to chamber 6. Outlet pipe 20 of pump Pa also communicates through non-return valve A r  with chamber 6. If spindle A 1  requires to be driven at high speed then shaft 2 will be driven only at low speed, and clockwise movement of body part 40 will nearly close a valve 3 with respect to seatings in a part 47. This causes switch 7 to be operated by member 51 to switch on motor M 2  to drive pump Pa which delivers fluid to chamber 6 and causes PC to act as a motor, shaft 2 rotating clockwise. As the requirements of spindle A 1  become less, more fluid from pump Pa emerges from pipe 46 and impinges on member 9 which actuates switch 10 to cut off motor M 2  and thus stop pump Pa.
