Abstract: 657,476. Testing balances of watches. COMPAGNIE INDUSTRIELLE DE MECANIQUE HORLOGERE. April 21, 1947, No. 10576. Convention date, June 21, 1946. [Class 139] In apparatus for testing and adjusting the frequency of oscillation of a balance wheel unit, the balance wheel unit to be tested and adjusted and a standard balance wheel unit are arranged to control contacts of separate switches in a circuit including an ammeter, a voltage source and a neon lamp, in such a way that a series of electric impulses is transmitted to the neon lamp and the resulting average current is measured by the ammeter. The circuit, Fig. 1, comprises a microammeter 16, a neon lamp 15 having a resistance r 1 , a switch R controlled by the balance wheel unit to be tested, a switch E controlled by the standard balance unit and voltage supplies U and u the latter being shunted across the switch E and in series with a resistance r 2 . The arrangement is such that the neon lamp 15 is excited and lit by a voltage U Œ u when the switch E is open while the lamp receives and remains lit by a working voltage U when the switch E is closed. The lamp 15 is extinguished when the switch R is opened. The balance wheel unit to be tested is fixed in a jig as shown in Figs. 5 and 6, the staff being support in bearings C 1  C 2  and two insulated contacts G 1 , G 2  embracing the outer convolution of the hair--spring. The contacts G 1 , G 2  form the switch R which is opened as the balance passes through its mid position.. The switch E is formed in the same manner by two contacts embracing the outer convolution of the hair-spring of the standard balance. unit. The outer end of the first mentioned hair spring is gripped between two rollers M 1  and M 2  one of which is rotatable to lengthen or shorten the hairspring in accordance with the reading on the microammeter. The hair-spring is then. bent at the position at which it is to be attached to the balance cock of a movement. The Specification as open to inspection under Sect. 91 comprises also an arrange-- ment in which the balance unit to be tested and the standard balance unit are arranged to send " ticks " to associated microphones one of which through an amplifier and relay periodically lights a neon lamp and the other of which controls the speed of a motor which constantly rotates a radially marked disc. This subject-matter does not appear in the Specification as accepted.

Abstract: 540,126. Thermionic valves and circuits therefor. SCHUMANN, W. O. April 11, 1939, No. 10998. Convention date, April 11, 1938. [Classes 39 (i) and 40 (v)] A gas filled valve with a grid capable of stopping the discharge when it reaches a certain potential is so arranged that the potential of the grid is altered when the stopping potential is reached so that the current, instead of being stopped is kept constant or reduced to a desired extent. Fig. 3 shows an arrangement for this purpose in which the grid 2 is connected, not only to a battery e or other source of potential, but to the anode through a condenser C and resistance r 1 . When the current commences to fall rapidly owing to the grid reaching the critical negative potential its potential is raised by the discharge through the condenser C and the current restored. In a modification the grid is connected to the anode through the source of grid potential and the condenser C dispensed with. Other arrangements are described in which the required potential is furnished from a second grid. In a further modification the action of the grid is regulated by the change in ionization produced by electrons accelerated by a second grid, the potential of which is regulated in accordance with the current.
