Title: Improvements in and relating to electromotive drives for calculating machines
IPC: G06C23/06
Filed: 1921-12-08
Abstract: 172,640. Optische Anstalt C. P. Goerz Akt.-Ges. Dec. 11, 1920, [Convention date]. Thermal switches; automatic circuitbreakers; time-limit devices. - When a motor starting key is depressed, a rod rotates a lever 2 which bv means of a roller 5 displaces a slide-bar 6 against the action of a spring 13. The bar is guided by two pegs 11, 12 and has two pins 15, 16 for operating bell-crank contact levers 18, 19 respectively controlling the motor circuit and a heating circuit 23 for a bimetallic strip 14. The first action of the lever 2 is to swing the bar 6 to the right about the peg 12 to release the lever 18 and so close the motor circuit, the connection between the motor and the machine having meanwhile been effected by the release by the lever 2 of a pivoted spring-controlled arm 4. Upon further movement of the lever 2, the bar pivots about the peg 11, the lever 19 is released, and the heating circuit completed. A notch 10 in the bar also escapes from the peg 12 and the bar slides upwards until its shoulder 7a engages the free end of the strip 14. As the latter warms up, it forces the bar down again to re-engage the notch 10 with the peg 12 and the lever 19 consequently breaks the heating circuit. The strip now begins to cool and straighten and when its end reaches the shoulder 7 the bar 6 resumes its original position and the motor circuit is broken. Instead of the starting key operating the lever 2 by mechanical connection it mav close an electric circuit including a motor, the rotor of which is coaxial with the lever 2.

Title: Production of iron biscyclopentadienyl and alkyl and aryl derivatives thereof
IPC: C07F17/02
Filed: 1953-12-04
Abstract: A cyclic process for the production of iron bis-cyclopentadienyl and its alkyl and aryl derivatives comprises reacting cyclopentadiene or an alkyl or aryl cyclopentadiene with elemental iron at a temperature between 400 DEG  and 800 DEG  F., oxidizing the resultant passive iron with an oxidizing gas possessing a free energy of oxidation between + 2000 and - 5000 calories per gram atom of iron at a temperature between 600 DEG  and 1600 DEG  F., reducing the so-formed oxidized iron reactant with a reducing agent as defined below to produce a reactive iron surface and thereafter reacting the reactivated elemental iron with the cyclopentadiene charge.  The cyclopentadiene may be diluted with an inert gas.  The oxidation may be carried out with steam until about 3 per cent of the total iron is oxidized.  Reduction may be carried out by means of hydrogen, a hydrogen-containing mixture or carbon monoxide.  The elemental iron may be obtained by reduction of natural or synthetic iron oxides (haematite, magnetite or a hydrous oxide obtained by precipitation of a salt such as ferric sulphate with ammonia), by decomposition of iron carbonyl or by heating an iron salt of an organic acid such as ferrous oxalate. It may be supported on a carrier such as porous aluminium oxide. Its activity may be enhanced by addition of CaO, BaO, B2O3, MgO, V2O5, ZrO2, SiO2, kieselguhr or oxides of chromium and molybdenum.  The mixture of liquid hydrocarbons obtained in the manufacture of coal gas, carburetted water gas, oil gas, or a C5 fraction from cracked petroleum oils (all of which contain cyclopentadiene) may be used as the cyclopentadiene charge.
