Filed: 1928-09-21
Abstract: 319,922. Fahy, F. C., Wilkinson, W. K., and Parkinson, J. W. Sept. 21, 1928. Star-delta starters in which movement from the neutral position to the delta position is prevented and when the allowable movement to the star position for starting has been made the movement to the delta position must be effected rapidly have a toothed cam e on the switch shaft normally serving, in the neutral position, to prevent anticlockwise movement of the shaft (to the delta position) bv its engagement with a pendulous catch g. Clockwise movement to the star position is possible, see Fig. 4, and thereafter the shaft may be turned rapidly through the neutral position to the delta position. If the movement is slow the pendulous catch has time to engage the toothed cam in the neutral position and prevent completion of the movement. The switch shaft is normally held in the neutral position by spring-connected centralizing levers j engaging a projection i on the shaft. In the delta position a catch n engages a pin o and the catch can be freed by hand through the rod q or automatically by a no-volt or overload coil.

Abstract: 622,289. Arc lamps. GRETENER, E. Sept. 11, 1946, No. 27356. Convention date, Sept. 11, 1945. [Class 39 (i)] An arc lamp with a high intensity arc using air current concentration has a revolving disc as a negative electrode. As shown in Fig. 2 an arrangement may be provided to keep the cathode spot fixed in space independent of the radius of the negative electrode N. The feeler A is pressed against the edge of the disc N and by means of a rack and pinion causes the disc to be moved towards the anode P as the disc gets smaller. Two contacts A1, A2, may be provided for starting, and to limit movement of the disc. On starting, the disc touches the anode and the lever ZH makes contact with A1 and energizes the magnet M, which holds the lever ZH in contact with A2, the running position. Thus, owing to the contact A1, the disc can never move too near the holder of the positive electrode.

Title: An improved method for the production of dehydrated alcohol
IPC: B01D3/00
Filed: 1924-11-17
Abstract: 224,921. Barbet, E. A. Nov. 17, 1923, [Convention date]. Alcoholic liquids, distilling.-In rectifying alcohol, the proportion of water in the distillate is decreased by conducting the rectification under reduced pressure. At an absolute pressure of 70 mm. alcohol free from water is obtained. The rectification is carried out in a column H, H<1> maintained under reduced pressure by a compound pump P which may be driven electrically by three-phase current to obtain a uniform number of revolutions. The column is supplied with alcohol vapours by a pipe 1 from a purifying column A, B. The vapours cause the residual water in the base of the column to boil at the reduced pressure, and are drawn into the column through a pipe 11. The condensate from the condenser J is in part returned as reflux by a pipe 2 and in part passes to receivers L, L<1>. The uncondensed gases and vapours are discharged by the pump P into a column R supplied with cold water. The alcoholic liquid is passed into a tank T and returned to the column. Amylic and butylic products are drawn from the column by pipes 7, 8 into receivers Q - - Q<111>. A second pump P<1> is used to exhaust these receivers after they have been discharged. In the purifying column, fermented liquors preheated in a tubular heater E by the residual liquor are admitted to purifying plates B. Light products are separated on the plates B<1> and pass to a condenser C. The section a from which the vapours are withdrawn to the column H is connected to the vapourregulator F.

In a powder clutch, to permit free relative movement of a disc 7 under pressure of the powder 4 in a surrounding casing 3, the disc 7 is universally mounted on its shaft 5 by two groups 8 of radially inclined tangential coilsprings. This permits both the casing shaft 1 and disc shaft 5 to be mounted in external bearings 2, 13 which need not be accurately aligned. A flexible seal 11 bearing on a powderproof inner ball-bearing 12 is provided between the casing 3 and shaft 5. The powder 4 is in the form of a metallic shot, the diameter of which is more than 0.2 mm., permitting a slight slip between the disc 7 and casing 3 (slip between 0.1  and 0.01 per cent) and more slip on overload. To increase the torque transmitted the surfaces of the disc and/or the casing 3 may be locally roughened by metallisation or hammering to form rounded deformations. The contact pressure between the disc 7 and powder 4 may be increased by providing the ring with slight undulations, the size of which is generally not more than 15 per cent of their pitch, and the disc may be externally and internally round or polygonal.
