Filed: 1938-10-12
Abstract: 520,147. Sewing-machines. FAIRWEATHER, H. G. C. (Singer Manufacturing Co.). Oct. 12, 1938, No. 29506. [Class 112] [Also in Group XXVI] The feed-advance eccentric of a sewing- machine is made of variable throw, and is adjusted by rotation relative to the shaft which carries it, such relative rotation being normally positively prevented. The eccentric 23 is formed on a member 22 slidable in a groove across a disc 21 secured to the shaft 14, and has a large bore, elongated transversely, receiving a second eccentric 24 forming part of a disc 26 which is angularly adjustable on the shaft 14. Adjustment of the disc 26 causes the eccentric 24 to move the member 22 on the disc 21, thus varying the throw of the eccentric 23 and consequently the feed. The disc 26 is secured in its adjusted position on the shaft by a member 28 sliding in a transverse guide in the disc and having offset teeth 29, Fig. 6, which, engage teeth on the periphery of a flange 32 of the feed-lift eccentric 33, which is integral with a bevel bear 60 driving the loop-taker shaft; the member 28 is moved to the locking position by a spring 36 and by centrifugal force due to the greater weight of the end opposite the teeth 29. In order to adjust the disc 26, a plunger (not shown) in the standard of the machine is pushed in against a spring to engage notches in the members 26, 28 and at the same time move the member 28 so that its teeth are disengaged; the shaft 14 is then rotated while the member 26 is held against rotation, the required position being indicated by a pointer on the driving pulley of the machine, and the plunger is released to allow the member 28 to return to the locking position and to free the member 26 for movement with the shaft. Specification 503,365 is referred to.

Forward/reverse speeds are effected by turning, i.e. rocking the lever 3, together with the second potentiometer unit 2, about the axis of shaft 10 (Fig. 2) which is thus turned to operate the 1st potentiometer unit 1. Left/right turning control is effected by simply turning the lever 3 about the axis of shaft 20 (Fig. 1) which is thus turned to operate the second potentiometer unit 2. The lever 3 is universally movable within a guide slot 40 in the casing 4, the slot 40 being shaped to increasingly restrict left/right turning control movement of the lever 3 with increasing forward or reverse control movement of the lever 3 to automatically prevent overturning of the wheel-chair on bends at increased forward/ reverse speeds. The speed and steering roles of these potentiometer units 1 and 2 may be interchanged to suit particular applications. The lever 3 may be constructed as a spring- loaded dead-man's type handle to shut off the controls and brake the wheel-chair to a stop when the lever 3 is manually released.

Title: Process for the manufacture of carbon and carbon-dioxide from carbon-monoxide
IPC: C01B31/00
Filed: 1930-10-03
Abstract: In the catalyst decomposition of carbon monoxide into carbon and carbon dioxide, the catalyst, such as iron, nickel, tungsten, or molybdenum, is deposited on carbon black or on a carrier such as magnesium oxide which can be removed from the product chemically by solution.  Activating agents, such as caustic alkalies or materials producing the same at the temperature of the reaction, or alkaline earth oxides, may be added.  Fresh catalyst may be periodically or continuously introduced, e.g. in the form of the carboxyl of iron or nickel.  Removal of the catalyst from the carbon may be effected by reaction with carbon monoxide at 50 DEG  C. at atmospheric pressure or 100-180 DEG  C. at pressures of from 30 to 60 atmospheres. Alternatively, the removal is effected by treatment with acid, e.g. iron is removed by heating with hydrochloric acid and nickel by nitric acid.  Decomposition of the carbon monoxide is carried out at normal or increased pressures, e.g. 100 atmospheres.  Two examples are given, using nickel and iron mixed with carbon black respectively as catalyst, completion of the reaction being effected by the use of a second apparatus or by passing the gas first over partly exhausted catalyst. Specification 326,913, [Class 90, Non-metallic elements], is referred to.
