Title: Improvements in operating members for emergency stop switches for electrical apparatus
IPC: H01H3/02
Filed: 1952-07-05
Abstract: 731,687. Hand-actuating devices for switches. CRABTREE & CO., Ltd., J. A., WINTLE, T. D. G., and HILL, W. E. June 30, 1953 [July 5, 1952], No. 16961/52. Class 38 (5). An operating member for an emergency stop switch comprises a helical spring 9 disposed between a fixed cup-shaped member 1 secured to the switch casing, and a cap 6 containing a tubular member 7a carrying an integral, arcuate plunger 7. The latter passes through an arcuate slot in the member 1 and is notched at 7b, the spring being torsionally stressed so that when the cap is depressed to cause the plunger to open the switch contacts, the spring rotates the cap and causes notch 7b to engage the slot in member 1 to retain the cap in the " switch open " position. On rotating the cap to disengage notch 7b, spring 9 projects the cap to its outward position and the switch contacts close. In a modification, Fig. 4, cap 12 carries a three-pointed member 17, the points being normally positioned in recesses 18 in the fixed member 13. On depression of the cap and its subsequent rotation by spring 11, the points ride over shoulders 18a to retain the switch " open."

Title: Improvements in or relating to the brewing of malt liquors
IPC: C12C7/00
Filed: 1921-06-22
Abstract: 186,161. Hyde, C. F. June 22, 1921. Mashing-processes.-The coarse meal and grits obtained by crushing malt for brewing purposes are separated from the fine meal, and are mashed to render the starch soluble, after which the mash may be used as mashing-liquor for the remainder of the ground malt, or the latter may be doughed into it. The ground malt, issuing from the mill 3, falls on a sifter 4, through which the fine meal passes to a hopper 5, and the coarse meal and grits to a hopper 6. The husks with adhering grits pass to another mill 7, ana therefrom to a sifter 8, through which the grits pass to the hopper 6, the husks passing over the sifter to the hopper 5.

Patent GB-357088-A (GB)
Title: Improvements in apparatus for sorting letters, cards and the like
IPC: B07C3/08
Filed: 1930-06-04
Abstract: 357,088. Sorting letters &c. WITHERUP, J., 5, Redvers Drive, and BURT, G., 38, Moss Lane, both in Orrell Park, Aintree, Liverpool. June 4, 1930, Nos. 17110 and 28681. [Class 117.] In apparatus for sorting letters &c. the letters are fed singly from a file to an observation station, from which they are picked up by a series of carriers having selective devices set in accordance with the address and coacting with corresponding fixed devices at the collecting stations for releasing the letters. The apparatus described consists of a series of arms B<1>, Fig. 1, carrying grippers D<1>, D<2> over an annular series of collecting openings C. The grippers consist of a comb D<1>, Fig. 10, and pivoted holder D<2>, and take up the letters from a similar form of holder at the point H. The grippers are opened at the discharging stations by the pivotal movement of a bar B<2> on the arm B<1> which is produced when one or a combination of pins F carried thereby engages the correspondingly situated fixed tappets F<2> disposed opposite each of the openings C. The pins F are normally held up by latch levers f<2>, Fig. 9, and are set when a corresponding cam or tappet G on the frame is released by the actuation of a key on the control board. This tappet releases the latch f<2> allowing the corresponding pin F to drop. The cam surface b5 on the carrier resets the tappet under its holding latch g<3>. At the discharging stations, the fixed tappets F<2> open the gripper and reset the pins. The letters are fed from a file L by a continuously moving friction band M<1>, the foremost letter being released from a detaining finger by a suction member K which is swung against it by mechanism actuated by any one of the control keys. From the file it is passed behind an observation window O by means of a friction belt M<2> and rollers and is temporarily held by a retaining member N while the address is read. The actuation of the control key displaces the member N and allows the letter to pass the stampcancelling printing roller P to the take-up station H. The controlling keyboard is associated with a synchronizing device consisting of a ratchet wheel R, Fig. 4, rotated in unison with the carrier, and coacting with a toothed lever r<1> to prevent the operation of the keys until the proper moment. The key may consist of a single arm movable to different angular positions and in any position actuating a rod s<2> which through the levers 8, 2 actuates the suction device K and stop mechanisms. Alternatively, the board may have separate keys for each setting, each key also actuating the synchronizing and associated mechanisms. An indicator Q may be operated in connection with each setting. The connection between the keyboard and the setting mechanisms G may be mechanical, pneumatic or electrical, and the gripper and holding devices may be pneumatic. In a further modification, the grippers may be carried by an endless band.

Abstract: 443,072. Arc converters. MARX, E., 431, Husarenstrasse, Braunschweig, Germany. June 14, 1935, No. 17190. Convention date, June 16, 1934. [Class 39 (i)] The pressure in a closed gas-circulating system of an arc converter is maintained by means which supply gas thereto, Main electrodes 5 and screen electrodes 4 are located within an insulating tube 1 which is provided with gas distributers 2 divided intc two parts 6, 7 by partitions which support the electrodes 4. Gas flows through the cooler 13, compressor 12, pipes 8, 9 to the parts 6 from which it flows, in two parallel paths, through the space between the electrodes 4 and tube 1, and through the electrodes 4 to parts 7 and pipes 10, 11. Cylinders 15 containing compressed gas are connected to a pipe 20 through a two-way valve 17 which is automatically controlled by means 21 to disconnect one cylinder when the pressure therein falls, and connect the other cylinder to the pipe 20. A pipe 24 connects the valve 23 to the system, and pressure-responsive means 22, which preferably is arranged in that part of the system in which the lowest pressure obtains, is adapted to control the valve 23 to maintain the pressure in the system. The valve 23 may be replaced by a compressor to which a reserve compressor may be connected in parallel. The minimum pressure in the system may be atmospheric.

Title: Improvement in and relating to driving devices for the counting mechanism of dry gas meters
IPC: G01F15/06
Filed: 1930-06-04
Abstract: 362,897. Gas meters. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(Pintsch Akt.-Ges., J. ; 71, Andreasstrasse, Berlin.) June 4, 1930, No. 17255. [Class 54.] In a dry gas meter the movement of the diaphragm operates a lever 6a to rock a lever 6 passing through a gastight diaphragm in the wall of the measuring chamber and the movement of the lever 6 is transmitted to the counting mechanism by a friction drive which transforms its rocking movement into a unidirectional rotary movement. In Fig. 2, each of two rods 7; 8 connected to the lever 6 is connected by two pivoted levers 10b, 10a to the spindle 16 of a disc 11 operating the counting mechanism. The downward movement of the rod 8 and the upward movement of the rod 7 press balls 13 arranged between the levers 10b, 10a into contact with the disc 11 and move the disc in a clockwise direction. In a modification the balls are dispensed with and the two levers 10b are formed with cam surfaces which tend under the pressure of springs to engage the disc. In Fig. 3 the rods 7, 8 are connected to levers 10 rocking on the spindle 16 and carrying spring-pressed balls 13 or wedges engaging the disc 11. In order that the dead motion in the mechanism may not be affected by the wear of the parts the oblique friction surface engaged by the ball &c. may be of logarithmic spiral form. In Fig. 4 the rod 7 rocks a disc 21 and che rod 8 a disc 22 on the hub 18 of a disc 20 operating the counting mechanism. The disc 21, 22 are formed with oppositely disposed logarithmic spiral recesses in which are arranged spring-pressed balls engaging depressions in the rim 19 of the disc 20. In Figs. 9 and 12 a single rod 33 connected to the lever 6 carries a fork 34 having pins 35 engaging recesses 52<1>, in friction discs 36, 36<1> rotatably mounted on the hollow pins 51, 52 of friction wheels 46, 47. The discs 36, 36<1> driving the counting mechanism 44 are each provided with two friction surfaces 64, 65 of logarithmic spiral form and spring-pressed balls 37 are arranged between the friction surfaces andthe inner surfaces of the wheels 46, 47.
