Title: Improvements relating to the steering wheels of road vehicles
IPC: B62D1/19
Filed: 1936-11-02
Abstract: 478,150. Steering road vehicles. HAWTHORN, H. R. Nov. 2, 1936, No. 29744. [Classes 79 (iii) and 79 (v)] Steering control means comprises a steering shaft 1, an upper shaft section 6 connected to the steering shaft and the steering wheel 4 through spaced joints or pivots 3, 5, means for locking the . j joints to prevent relative angular movement of the parts connected by them, and hand-operated means for releasing the said locking means of the two joints simultaneously. Thus the steering wheel can be readily moved out of the way of the driver when desired and can be locked in its new position to prevent unauthorized use of the vehicle. In the construction shown the shaft section 6 is connected to the shaft 1 and the wheel 4 by rule joints 3, 5 formed with stops 7 to limit angular movement. The joints are locked in the normal position, shown in full lines, by means of spring bolts 10 sliding in the shaft section 6 and having lugs 9 projecting into notches in the joint parts on the shaft 1 and the wheel, so that the wheel is locked to the part 6, and the part 6 is locked to the shaft 1. The inner ends of the bolts are formed with overlapping slots 13 through which passes a rotary cam 14 which has cylindrical heads 15 rotatable in the part 6 and carries an arm 17 controlled by a jointed rod 19 20 furnished with an operating knob 22. When it is desired to move the steering wheel out of the way the knob is depressed and rotates the cam 14 to withdraw the bolts 10 from the notches and thus free the joints. The shaft section 6 can now be swung upwards parallel to the dash-board 2, as shown in broken lines, and the wheel 4 can be swung about the part 6 also parallel to the dashboard. The steering wheel is marked to show the position in which the joint pivots are horizontal to allow the desired movements. The joint 21 in the rod 19, 20 is coaxial with the upper joint 5 when the knob 22 is depressed. In order to prevent unauthorized use a hasp may be mounted on the dashboard adapted to embrace the shaft and to engage and lock in a key-controlled lock on the dash-board. According to the Provisional Specification the cam may be controlled by a cable.

Title: Improvements in or relating to frequency-shift telegraphy receivers
IPC: H04L27/14
Filed: 1957-09-24
Abstract: 872,572. Receivers for alternating current telegraphy. PHILIPS ELECTRICAL INDUSTRIES Ltd. Sept. 24, 1957 [Sept. 27, 1956], No. 29952/57. Class 40(3) In a receiver for frequency-shift telegraphy in which signals demodulated at 3<SP>1</SP>, Fig. 1, are applied to control a relay 20 via a pulse repeater and limiter 14, 15, a D.C. restorer is provided between the detector and pulse repeater in the form of two series-connected diodes 26, 27 with a bias supply 28, 28<SP>1</SP> connected in the direction to cut-off the diodes, the terminals 33, 35 for the input signals being connected to the junction of the diodes and to the centre tap of the bias supply, the first connection including a capacitor 25, and the terminals 32, 35 for the output signals being connected to the junction of the diodes and to the centre tap of the bias supply. The input signal, Fig. 2(a), which may have its D.C. level displaced by an amount #E due to variations in transmitter frequency or receiver tuning, is arranged by adjustment of input potentiometer 29 to have a peak-to-peak amplitude E equal to the potential of the bias supply. In operation, capacitor 25 is charged positively or negatively in dependance upon the direction of displacement #E and causes a potential to be added to the input-signal whereby the signal appearing on the plate remote from the input is restored to the correct D.C. level. For the case illustrated, where #E is displaced negatively, capacitor 25 charges positively via diode 27 to the extent (#E) that the negative swing of the input (E/2 + #E) exceeds the potential E/2 of bias source 28<SP>1</SP>. A potential #E is thus added to the input and the output appears as shown in Fig. 2(b). During periods of rest grid current flowing to valve 14 may alter the charge in capacitor 25 with the result that the D.C. level is incorrect when signalling is resumed. This effect is avoided by supplying signals to the junction of the diodes which are in phase with the input signals but of greater amplitude. The signals are supplied via a resistor network 30, 31 which may be connected either to the output of the pulse repeater as shown or to the output of detector 3. The grid current for value 14 is then supplied via the resistor network and the charge in capacitor 25 maintained unaltered. In a modification, Fig. 3 (not shown), bias source 28, 28<SP>1</SP> is replaced by a bias network connected between terminals 5 and 7 of the main voltage supply. In a further modification (not illustrated) the bias may be obtained from a transformer and rectifier circuit arranged to be energized from the incoming signal applied to detector 3.

Abstract: 1,151,186. Locks. JOHN TANN Ltd. 19 Sept., 1967 [4 July, 1966], No. 29967/66. Heading E2A. A key operated lock including a number of bolt detaining members, e.g. sliding members or, as shown, pivotted levers, is provided with retaining means, e.g. a pawl 29a, for holding at least one of the levers in an inoperative position, Fig. 14, the remaining levers normally occupying bolt-obstructing positions and being displaceable by a temporary key 33 to free the bolt, use of another key 34, intended for permanent lock operation, resulting in actuation of means, e.g. a cam surface 32 on lever 16, to disengage the retaining means, Fig. 16, so that all the levers become operable by the permanent key, while the temporary key is no longer effective in operating the lock. The lock illustrated includes ten levers (12-21), Figs. 13 and 15 (not shown), of which levers 12-15 and 17 are initially held by the pawl 29a, levers 18-21 function normally and lever 16 is not operable by the temporary key 33, the latter being for use by a workman installing the lock. The permanent key, which is for use by the authorized user of the lock, has steps identical with those of the temporary key for operating levers 18-21, whilst the other steps differ. In particular, the step corresponding to lever 16 is effective to raise the latter, thus tripping the pawl 29a and allowing lever springs 23 to move levers 12-15 and 17 to their operative positions. Each of the levers, except lever 16. is formed with the usual gate, through which the bolt stump or talon 28 may pass when the respective lever is correctly oriented by the key. The look casing comprises a plate 1, formed with four upstanding corner posts 3, over reduced-section free ends of which a suitably apertured face plate (not shown) is fitted. The face plate is secured by screws engaging tapped posts 6.
