Title: Improvements in locking means for securing a nut on a screwed member
IPC: F16B39/10
Filed: 1952-08-21
Abstract: 743,247. Locking nuts. PISCHEK, F. Aug. 21, 1952, No. 20980/52. Class 89 (1). In means for locking a nut on a bolt &c., a washer a is prevented from rotating relatively to the bolt and has radial tongues 7 spaced equiangularly, and a plate c has a polygonal opening 8 to fit the nut and a series of notches 9 or apertures 9<SP>1</SP> to receive one of the tongues 7, the angular spacing of the notches &c. having a vernier relation to the spacing of the tongues so that engagement of a tongue and notch &c. may be secured in any position of the nut. The clearance between the faces of the opening 8 and the sides of the nut is such that the plate c may be rotated through an angle α relatively to the nut, and the angular spacing of the tongues and notches are respectively unequal multiples of α to secure the vernier effect, so that in any position of the parts after tightening the nut, one of the tongues will be within an angle α of one of the notches and rotation of the plate c within the limits of its clearance on the nut will produce exact registering of that tongue and notch. Both notches 9 and apertures 9<SP>1</SP> may be provided on plate a, Fig. 2, and the notches &c. may be slightly wider than the tongues 7. Rotation of washer a may be prevented by a bent-over flange 2, Figs. 7 and 8, or the flat edge of the washer may engage part of the work, such as the fish-plate of a rail-coupling. The tongue 7 registering with a notch &c. is bent up and clinched as shown in Figs. 7 and 8 and the tongues originate from within the arcuate edge of the washer, as shown in Fig. 1, to prevent fracture during bending.

Abstract: 149.235. Huth Ges., Dr. E. F., Rosenbaum, B., and Loewe, S. Aug. 18, 1917, [Convention date]. No Patent granted (Sealing fee not paid). Electric selectors.-In a relaying system for use in wireless telegraphy and telephony, automatically working intermediate stations are provided, which transmit the message from the calling- station to the called station. Fig. 2 shows a part of the system adapted for wireless telephony, the primary transmitting station being indicated by the microphone 11, transmitter 12 and aerial 13, whilst an intermediate station is depicted by the aerial 14 and its associated apparatus. In its normal condition, the intermediate station is ready for reception, the antenna 14 being connected to the receiver 16 through the change-over switch 15. The receiver 16 magnetizes the rotating steel band 17 in accordance with the received message. A distinctive call of three notes is transmitted at the end of the message, which is transferred to the wire 17, and by exciting the three detecting-coils 18 in a certain sequence actuates the relays 19, which close corresponding local circuits to change over the aerial from the receiving to the transmitting apparatus. A detecting-coil 21 is influenced in accordance with the magnetization of the wire 17, the potential variations being magnified by the relay 22 and impressed upon the grid of the transmitting-valve 23. The message and the final call is thus transmitted to the next intermediate station, which acts in a similar manner. When the transmitter 23 repeats the final call, the relays 19 are again actuated and change over the switch 15 to the receiving position.

Abstract: 1437671 APC systems; pulse modulation circuits THOMSON-CSF 14 May 1974 [14 May 1973] 21396/74 Headings H3A and H4L An automatic frequency and phase control system suitable for synchronizing a plurality of TV camera assemblies to a central station comprises at the central station 1, a phase and frequency comparator 7 fed by signals received from an oscillator 6 at a remote station and from a reference generator 5 for producing a first yes-no type of phase difference signal and a second yes-no type of frequency difference signal representing also the above phase difference signal, a circuit 8 for transmitting periodically the difference signals at a certain carrier frequency and a correcting circuit 10-15 at the remote station responsive to the received signals to apply a correction signal to the oscillator 6, the sign of which is determined by the value of the frequency or phase error signal received and having an amplitude which differs according to whether the received signal differs or not from the preceding one. At the central station, the frequency and phase comparators produce respective binary outputs the first one or both of which are sampled, encoded and transmitted as a phase shift modulation or a carrier along a cable 4. At the remote station, the received signals are demodulated, decoded and separated into clock and data signals. The clock pulses corresponding to the transmitted carrier are applied via a pulse width modulator 10 to an inverter 12 which depending on the sign of the binary error data pulses applied to it enable the selected one of current sources 13, 14 to charge or discharge a capacitor 15 for a period determined by the clock pulse duration. When the frequency difference is large, the detected error signal has only one sign and only one current source is effective. The error signal changes in sign when locking is reached. A sequence detector 11 detects this change of sign to reduce the pulse width and also of amplitude of pulses delivered by modulator 10. The capacitor 15 is then alternately charged or discharged in small increments until the system settles down to a synchronized state. Fig. 2 (not shown) relates to the sequence detector 11 and includes a pair of cascaded shift register stages and combination logic gates. Fig. 4 (not shown) relates to a combined frequency and phase comparator. A pulse width modulator (see Fig. 3) comprises an amplitude comparator 30, an RC circuit 38, 35 having a large time constant and applying a steady voltage U 0  to a terminal of the comparator in the absence of any input pulses to shunt FET 37, a second RC circuit 31, 32 periodically discharged by clock pulses applied to shunt FET 34. The comparator output produces a change of state when capacitor 31 is discharged by the clock pulses and a further change of state when the charge voltage exceeds the steady voltage at the other input. The output pulse width is altered by applying pulses to FET 37 to change the charge voltage held by capacitor 35.
