Title: An improved time-measuring apparatus employing an auxiliary movement and a synchronous electro-motor
IPC: G04C15/00
Filed: 1936-04-29
Abstract: 452,404. Alternating-current motors. LANDIS & GYR AKT.-GES., 1, Hofstrasse, Zug, Switzerland. April 29, 1936, No. 12146. Convention date, June 15, 1935. [Class 35] [See also Group XVIII] A clock normally driven by a synchronous motor 3 and having an auxiliary movement, with escapement 25, in reserve is characterized in that the escapement is released by the residual rotation of the motor when the rotor axis is moved axially on current failure. When current flows, the axially acting magnetic force of the motor 3 moves the axis 5 of the rotor 4 to the right, Fig. 2, against lever 8 and spring 6. When current falls below a predetermined minimum, spring 6 moves axis 5 to the left so that a cam 9, as it rotates to rest, rocks a bellcrank 13 to raise a spring 12 and release the escapement 25. A pin 26 on crank 13 locks behind lug 27 on a lever 16 until the motor is again energized and rotates disc 18 and pin 17 to lower the lug 27.

Inside the cell, the shaft carries a series of insulating rings 14, and fitted on these in turned grooves 15 are the electrodes 16. The rings have bores 17 drilled through them in correspondence with holes 18 in the electrodes, and alternate electrodes are electrically connected, through the tubes so formed by springs 19. The end electrodes 16a and 16l are of opposite polarity, and these are held tightly against conducting collars 21, 20 carried on insulating rings 23, 22 on the shaft. The whole assembly is held firmly on the shaft between a shoulder 25 and a nut 27 on a threaded portion of the shaft. Outside the cell the shaft carries conducting rings 34, 35, insuated from it, and these are connected to the collars 21, 20 by means of conductors 39, 38 which pass through tubes 30, 29, lined with insulating material, which are drilled coaxial with the shaft.

In operation, the fluid enters and leaves the cell throuh apertures 6, 7, and makes contact with the rotating electrodes, which may be made of silver or copper according to the nature of the fluid and may be of the same or different metals. The direction and speed of rotation of the electrodes may be changed by means of a gear-box device if desired. The apparatus is suitable for the treatment of fluids containing solid particles, as any particles which adhere to the electrodes are immediately thrown off by centrifugal force.

Abstract: 729,914. Treatment of electrolytically-tinned iron. EISEN-UND HUTTENWERKE AKT.- GES. June 4, 1951, No. 13243/51. Class 41. In a process for melting-on the tin layer of an electrolytically-tinned iron band or sheet by means of induction or resistance heating the band or sheet is heated in two separate successive stages by separate heating devices in such manner that in the first stage the band or sheet is preliminarily heated to a temperature below the melting point of tin, to remove residual gas or liquid occluded by or deposited on the band or sheet during the electrolysis, and to form an alloy layer between the band or sheet and the tin coating, and in the second stage the band or sheet is heated to a melting- on temperature above the melting point of tin. In the arrangement indicated diagrammatically, an electrolytically-tinned band 1 is conducted through a heating device 2 wherein it is heated by induction or resistance heating to a temperature below the melting point of tin, but above 120‹ C. The band is then passed through a second heating device 3 for a shorter period, in which the melting-on takes place.
