Title: Remotely controlled receiver
IPC: H02J13/00
Filed: 1949-01-20
Abstract: 662,447. Electric control systems. SAUTER AKT.-GES. FABRIK ELEKTRISCHEN APPARATE, F. Jan. 20, 1949. [Jan. 21, 1948; Jan. 18, 1949] Nos. 1659/49 and 1660/49. Class 40 (i). [Also in Groups XL (a) and XL (c)] A receiver controlled from a central station over power lines by impulses of high frequency comprises a series resonant circuit connected across the line, the signal impulse voltage developed across the inductance portion of the resonant circuit being fed to the control grid of a cold cathode glow-discharge relay by way of a capacitively loaded rectifier of small time constant to enhance amplitude limitation at relatively high input voltages. A plurality .of control impulses at the same or different frequencies may effect selective control operations, through synchronous distributors at the transmitter and receiver. The series resonant circuit comprising the coil 14 and condenser 13, Fig. 1, is connected directly across the power lines 11, 12. When an impulse at the resonance frequency is sent over the line, the voltage developed across the coil 14 is fed over the rectifier 15 and protective resistance 16 to the control grid G1 and condenser 17 in parallel and fires the glow discharge tube 1 during the positive half-cycles of the power supply fed to the other tube electrodes from the secondary of the mains transformer 2. Amplitude limitation of the input signal is effected by the capacitative loading of the rectifier by condenser 17 or by suitable dimensioning of the coil 14. A relay 21 in the tube anode circuit operates for the duration of each control impulse. The first impulse, the starting impulse, energises over contact 22 a synchronous motor 3 which then drives a rotary distributor switch 6 in synchronism with a corresponding distributor at the control station (not shown). Cam operated contacts 5 provide a self-locking circuit for the motor which drives the distributor 6 for one revolution only from the starting position shown. During this revolution further control impulses at the resonant frequency are sent to operate the relay 21 as the distributor 6 rests on selected contacts whereupon the corresponding "on" and "off" windings of further relays 7, 8, 9, 10 effect the selected "on" or "off" control operations over lines 32-35. The transformer 2 may be replaced by a potential divider. In modifications, Figs. 5 and 6 (not shown), the impulse voltage developed across coil 14 is stepped up through a transformer before application to the rectifier-grid circuit. Three or five electrode glow discharge relays may be used. The synchronous distributors may be replaced by stepping switches or different control frequencies may be used, one for each control operation.

Abstract: 155,132. Roy, J. Jan. 20, 1920. Circular machines.-A brake-element is introduced between the cam-shell and needle-cylinder of a manually-operated machine to guard the cam-shell against movement during the pause between the back and forth strokes in reciprocation. The bed plate 10 has two offsets 11, 12 in the outer peripheral edge and one offset 13 in the inner edge. An inner annular flange 15 of the gear ring 14 seats, on the offset 11 and an offset 16 of the ring 14 supports the cam-shell 17 and has a flange 18 seated on the offset 12. When the cam-shell 17 is reciprocated, it is necessary that the same be held stationary during the pause between the back and forth movements, to avoid dropping stitches or breaking the yarn. This is effected by means of a brake member such as a blade spring 23 secured by a screw 24 to an enlargement 25 of the needle cylinder 19. The fres end 26 passes through an opening in the cylinder wall and bears against the inner wall 27 of the cam-shell 17. Modified forms of brake elements such as spring studs or plungers may be used. Fig. 6 shows a spring 39 which is housed in the recess formed by a flat portion 38 of the needle cylinder and exerts a braking action on the camcylinder wall. ,
