[Also in Group XXXVI] In a screening assembly for an electronic device, e.g. a thermionic valve, a screening can 1, Fig. 1, is formed with at least two external lugs 4, and a sheet metal saddle member, adapted for permanent attachment to a chassis or the like, includes an annular ring having an internal lip of inverted U-shaped cross-section having slots 9 through which the lugs 4 can pass and recesses 8 which the lugs engage after rotation of the can. As shown there are two alternative positions for the can which is urged upwards by a spring 2 in the top of the can or an annular spring at the top of the valve socket. The saddle member may be bolted to an apertured chassis, to the other side of which is secured the valve socket. Alternatively, the socket 14, Fig. 4, is formed with a flange 13 having slots 16 through which pass lugs 15 of the saddle, Fig. 3, and recesses 18 which are engaged by upwardly-bent lugs 17, after rotation of the saddle. In a further arrangement a flange is formed mid-way along the screening can and has external lugs which engage a saddle mounted on an auxiliary chassis, the can and valve extending through this chassis to a valve socket carried on a main chassis which is spaced from and parallel to the auxiliary chassis.

Abstract: 434,545. Maintaining defined speeds. IGRANIC ELECTRIC CO., Ltd., 147, Queen Victoria Street, London.-(Assignees of Stansbury, C. ; 12th Street, Milwaukee, Wisconsin, U.S.A.) April 5, 1934, No. 10338. Convention date, April 6, 1933. [Class 38 (iii)] [See also Group XXXVI] In order to control the speed of an electric motor in accordance with a speed standard, a reactive impedance is used to control the motor circuit having two members, relative movement between which varies the impedance ; the movement of these members is made dependent on the difference between the speeds of the controlled motor and the standard. One member may be driven through a slipping clutch so that the impedance may vary only between minimum and maximum values. The impedance, e.g. 28, Fig. 1, may be arranged in association with a resistance 21 to cause a phase shift between anode and grid voltages of valves 15, 16 connected to circulate a current in accordance with the change through a resistance 14 in series with the field winding of the controlled motor 12. A variable inductance or a variable condenser may constitute the impedance. Figs. 2 and 3 show the impedance 28 constituted by a winding 23 on a core driven by the motor shaft 24 and a yoke 31 driven by a standard speed shaft 38 through a slipping clutch 36 between limiting relative positions determined by stops 33, 34. Fig. 5 shows a form wherein a yoke 39 around a coil 23 has a core 40 variably inserted by the differential action between a screw 43 driven by the motor and the core 40 driven by the standard speed shaft. Fig. 6 shows in section a condenser 46, the plates of which are driven respectively by the motor shaft 24 and a standard speed shaft 38.

Title: Improvements relating to Ploughs, Cultivators and other Agricultural Implements.
Inventor: WALLACE DUNCAN MCNAUGHTON
IPC: A01B63/16
Filed: 1917-07-23
Abstract: 117,661. Wallace, D. M., and Everitt, A. July 23, 1917. Ploughs; cultivators. - Relates to motor - driven ploughs, cultivators, &c., having automatic raising and lowering gear of the kind in which crankmounted land and furrow wheels are moved towards one another by a winding gear put into action by a clutch under the control of a foot lever, a lever for manual operation also being provided. The invention consists in automatically disengaging the ratchet locking pawl of the hand-lever by actuation of the clutch-operating foot lever when the ploughs &c. are to be lowered. As shown in Fig. 2, the pedal lever i<2> operates the clutch rod h to throw the clutch o and winding gear p into action to draw the land and furrow wheels a, c together. During this movement the pawl m on the auxiliary lever f slips over the ratchet-shaped teeth on the quadrant rack e, as the lever f moves to its lowest position, as shown in Fig. 1, coresponding to the raised position of the frame. When the frame is to be lowered, pressure on the foot lever i<2> puts the clutch into action momentarily to relieve the pressure on the pawl m, which is at the same time retracted by means of a cam l operated through links k j, by a pawl i<3> on the foot-lever i<2>. The pawl is held out of action by the notched end m<1> of the cam whilst the frame descends by gravity. As the lever f returns to the position shown in Fig. 2, the links k, j, strike a fixed stop q throwing the cam l out of action.
