Filed: 1967-03-07
Abstract: 1,113,186. Printed circuits. SIEMENS A.G. 7 March, 1967 [8 March, 1966], No. 10603/67. Heading H1R. In a process for making a thin film circuit comprising at least one resistor and at least one capacitor, one surface of an insulating carrier 1 (e.g. glass or ceramic) is covered with a highresistance metal layer 2; a lower-resistance metal layer 3 is then deposited, followed by etching away of unwanted parts of the layers 2, 3; layer 3 is partially oxidized where resistors and capacitors are required, to produce a capacitor dielectric layer 6 overlying a lowresistance electrode 5; and the areas designed as resistors are further treated so as completely to oxidize at least layer 3 at 4. Where conductors are required, layer 3 is protected from any oxidation. The preferred metal for layers 2, 3 is Ta, the difference in resistivity of the layers being produced at the sputtering-on stage; alternatively, layers 2, 3 may comprise Ta/A1; Ni-Cr/Ta; or Ni-Cr/A1. The oxidation steps are preferably carried out by anodization. A second electrode 7 for the capacitor may be of Au applied by vapour deposition.

Patent GB-106663-A (GB)
IPC: D03D51/00
Abstract: 106,663. Crowley, J. F. May 30, 1016. Brake mechanism; stop-motions, shuttle. - In braking- means for electrically-driven looms or other machinery, a solenoid is energized to take off the brake when the motor switch is closed, and this switch is held closed by a trigger device, which can be released manually, by a safety device on the loom, or by failure of the current. The solenoid may be short-circuited after the brakes have been taken off thereby and the brakes be held off by a second trigger, which may be connected to the switch triggerdevice. The arrangement shown comprises a motor switch j adapted to be held closed by a tooth i<2> on the trigger lever i. A weight-applied brake b is taken off by the solenoid f. Contacts f<2> short-circuit the solenoid in the raised position of the core, and the brakes are held off by the engagement of the tail b<2> of the brake lever with a lever k connected to the trigger lever i by the rod l. A second lever m is connected to the rod l for engagement by the safety tongue n of the loom. If the tongue n is raised by the shuttles,vell or from other cause, it strikes the lever m and the switch is thereby opened and the brake applied. A holding-on coil o is also provided, the plunger of which drops and releases the trigger device if the current supply fails. If the solenoid f is constantly energized to hold the brakes off, the plunger g thereof is arranged, when it drops by failure of the current, to release the trigger and thus effect the opening of the switch. The core g may be held in the raised position by a shunt coil adapted to be energized when the core reaches its upper position.
Patent GB-573109-A (GB)
Title: Improvements in or relating to catalytic isomerization of paraffin hydrocarbons and catalysts therefor
IPC: C07C5/27
Filed: 1942-07-31
Abstract: A catalyst for the isomerization of paraffins is prepared by impregnating a dry porous carrier with anhydrous aluminium chloride, preferably under superatmospheric pressure, at from 250-700 DEG  F., and then subjecting it at the same or a higher temperature to a current of purging gas.  Excess aluminium chloride is thereby removed, and a product obtained which will not lose substantial amounts thereof during the isomerization.  The chloride may be used alone or dissolved in such solvents as lower alkyl halides or polyhalides which are removed after the impregnation by slow heating with increasing temperature. Alternatively, the purging gas may be used to sublime the chloride and bring it into contact with the carrier.  Compounds known to have a solubilizing effect on the halide, e.g. methyl chloride or methane, may be used to accelerate the absorption.  Where impregnation is effected at an increased pressure of a few lbs./sq. in., temperatures are preferably about 250-375 DEG  F. with a contact time of 1-3 1/2 hrs., although times up to 25 hrs. may be used.  The subsequent purging, for example with hydrogen, hydrogen chloride, chlorine, nitrogen, methane or carbon dioxide, is then effected at about 250-500 DEG  F.  Suitable carriers are activated carbon, alumina, silica, alunite, diatomaceous earth, acid-treated clay, bentonite, montmorillonite, bauxite, and "Sil-O-Cel," "Super Filtrol," or "Porocel" (Registered Trade Marks). They may be preheated to about 800 DEG  F. for up to 18 hrs. prior to impregnation.  The process is applicable to the reactivation of spent catalysts of known type.  The catalysts are used for vapour phase isomerization of butane, pentane, hexane, heptane, 2-methyl pentane, their homologues, and mixtures such as gasolines or naphthas. Hydrogen, and promoters such as halogens and halides may be present. Contact times are generally 50-100 secs. with a feed rate of 0.2-3 vols. (measured as liquid) per vol. of catalyst per hr., and temperatures 150-450, preferably 275-330 DEG  F., with pressures up to, say, 180 lbs./sq. in.  The aluminium chloride content of the catalyst is about 8-35, preferably 8-12 per cent, based on the weight of carrier. Examples 1-4 describe the impregnation of preheated activated alumina, bauxite or activated charcoal by heating with aluminium chloride at temperatures between 260 DEG  and 310 DEG  F. for 17 or 18 hrs., followed by purging in nitrogen at from 325 DEG to 360 DEG  F., for 2 1/2 -3 hrs.  Examples 5-8 describe the use of these catalysts in isomerizing butane or pentane in the presence of 5-6 per cent of HCl, at 325 DEG  or 100-200 DEG  F. respectively.
