IPC: B60R25/00
Filed: 1919-07-21
Abstract: 152,772. Doyle, D. July 21, 1919. Locking while standing.-Means are provided for (1) freeing the road wheels from the engine and (2) locking them against rotation, a key-operated lock securing the means in either of these positions or in the position for normal running. In the form shown in Fig. 6, the rear end of the propeller shaft a can be coupled by a clutch c to the driving-shaft d or to the fixed casing e. In the mid-position shown, the road wheels are freed from the driving-shaft. The clutch c is operated by a rod f held in any one of the three positions by a lock. In the form shown in Fig. 7 applied to the change-speed gear-box, a gear-wheel 7 permanently connected to the road wheels may be engaged by a toothed sector X on a shaft v which is operated by a shaft t controlled by a lock 10. The shaft t has three locked positions, one in which the gear-wheel 7 is locked by the sector X, another in which the gears are free for normal running, and an intermediate position in which arms 1, 2, hold the change gears in neutral position so that the engine cannot drive the road wheels. When the gears are locked, a bolt 6 is moved by the shaft t to hold the cover of the gearbox in place. In a modification, the changespeed lever, or an independent lever, operates a. sliding plate having a cam-slot which effects the movement of the toothed sector X and the arms. 1, 2. ...

Title: Circuit arrangement for varying the contrast of a television picture
IPC: H04N5/235
Filed: 1963-05-13
Abstract: 1,049,641. Television. FERNSEH G.m.b.H. May 13, 1963 [May 12, 1962], No. 18816/63. Heading H4F. In apparatus for generating television picture signals, the signals are applied to a gate stage which is controlled so as to pass only signals corresponding to a predetermined area of the picture and a control signal is derived therefrom and employed to modify the contrast of the signals. In one arrangement the predetermined area, which is rectangular, may be adjusted in position over the picture area and may also be adjusted in size over the limits of <SP>1</SP>/ 25  to  of the total picture area. The control signal may be derived by: (a) a peak rectifier, (b) a rectifier responsive to the mean level of the signals, or (c) a limiter which passes only signals above a predetermined level and a rectifier which responds to the mean level of the signals from the limiter. The derived signal may control: (a) the intensity of a light source illuminating the subject being scanned to derive the picture signals, (b) the amount of light passing from the subject to the pick-up device, e.g. by controlling a variable density filter or an iris diaphragm in the light path, (c) the conditions of operation of the pick-up device, e.g. in the case of a vidicon pick-up tube the signal may control the potential of the target electrode, (d) the amplification of the picture signals (reference being made to the simultaneous clamping of the black level), (e) the directcurrent component of the picture signals. In a first mode of operation the control signal operates only during the scanning of the predetermined area, the signals from outside the area remaining unaltered. In a second mode, the control signal is applied to modify the whole picture signal and if the signal from outside the predetermined area exceeds peak white or peak black it is clipped at these levels. In a third mode, the control signal modifies only the signal from the predetermined area whilst the remaining signals are eliminated and replaced in a reproduced picture by white, black, grey or coloured areas. The outline of the predetermined area may be indicated by mixing peak white or black marking pulse in with the picture signals. In an extension of the invention, a plurality of gate stages are provided to derive a corresponding plurality of control signals which control signal production from a plurality of discrete picture areas. Brief descriptions are given of the application of the invention to: (a) a film scanner where the light source intensity is subject to control, (b) a film scanner employing a cathode-ray tube flying-spot scanner, the beam intensity of which is subject to control, and (c) an X-ray television system incorporating an X-ray image converter. A circuit is described (in block diagram form only) for generating line- and framefrequency pulses of adjustable width and timing for controlling the gate stage in the first arrangement referred to above.

Class 97(1) In an interferometer in which a beam of light is divided into two beams which are recontinued to produce interference bands and the value to be measured is determined from the displacement of the bands, the arrangement is such that the interference band of zero order is formed by a dark line. As shown applied to a gas refractometer light from a source 1 is directed by lenses 2, 3 and a prism 4 on to a light-transmitting reflector 6 of silver bv which it is divided into a reflected beam 6" and a transmitted beam 6<SP>1</SP>. The beam 6<SP>1</SP> passes into a chamber 13 containing the gas the refractive index' of which is to be measured, is reflected back through the chamber by the prism 7 and reflected by the surface 5 of the prism 4 to pass again through the reflector 6. The reflected beam 6<SP>11</SP> passes through chambers 14, 12. containing a standard gas such as air and is reflected by the surface 6 in coincidence with the beam 6<SP>1</SP> the resulting interference bands being observed in a telescope 9, 15 on a graticule 10. Thus the beam 6<SP>1</SP> is transmitted twice.;by the reflector 6 while the beam 6" is. reflected twice by that reflector which is so chosen that thereby a phase difference of # is introduced between the two beams so that the zero order interference band is dark. A polarizer 16 may be provided to give place to polarized light.
