Abstract: 787,806. Television. ELECTRIC & MUSICAL-INDUSTRIES, Ltd. Oct. 17, 1955 [Oct. 15, 1954], No. 29711/54. Class 40 (3). Frame sequential colour signals R + G + B are directed into separate channels by a gate 10 and displayed on cathode-ray tubes 1, 2 and 3 from which simultaneous colour signals are derived by storage-type pick-up tubes 7, 8, 9, the system being characterized by the use of low- and high-pass filter combinations 11 and 14 whereby only the low-frequency components RL and BL of the red and blue signals pass to tubes 2 and 3 whilst the high-frequency components RH and BH pass to gate 13 where they are added to the complete green signal G and applied to tube 1. 12 and 15 are amplifiers. 28 is a delay network introducing a delay equal to that introduced by the low-pass filters in filter combinations 11 and 14. The derived simultaneous signals may be utilized in any way; the Figure illustrates a low- and high-pass filter combination 16 to separate the green low-frequency components GL from the combined red, green and blue high-frequency signals MH in the output of pick-up tube 7 and an adder 18 and matrix network 17 for deriving a luminance signal EYL + MH together with either colour difference signals RL-EYL and BL-EYL or I and Q signals in accordance with American N.T.S.C. standards. The number of combinations of cathode-ray display and pick-up tubes may be reduced to one or two by the employment of the arrangements described in Specifications 778,180 and 778,181. The Specification describes a circuit, Fig. 2 (not shown), for the filter combinations 11, 14 and 18. Specification 778,179 also is referred to.

Title: Improvements in dash pot damping devices
IPC: G01G23/08
Filed: 1928-10-19
Abstract: 322,292. Marks, Sir G. C., (Toledo Scale Co.). Oct. 19, 1928. Dashpots for use particularly with weighing scales and of the kind in which means are provided to compensate automatically for changes in the viscosity of the liquid damping- medium resulting from changes in temperature, consist of a piston provided with ports and a valve member spaced therefrom over the ports, temperaturecontrolled means being provided to move the valve member towards and away from the ports so as to vary the leakage space. In the weighing-machine dashpot shown in Fig. 2, a piston is moved up and down in a cylinder by a rod 9 connected at its upper end to a. lever forming part of the weighing-machine. The piston shown in more detail in Figs. 4 and 8, consists of a rigid member 10 with ports 18 which are partly covered by a thermostatic element 17 made of two pieces of metal having different coefficients of expansion. When the temperature of the liquid medium rises, the thermostatic element 17 bends downwards and reduces the effective area of the leakage orifices, thus compensating for the loss of viscosity and ensuring a constant damping effect. A pin 22 engages freely a hole 23 in the element 17 and retains it in position. The member 10 and the thermostatic element 17 are adjusted relatively to one another by screw-and-nut mechanism at the upper end of the rod 9. Adjustment of the screw forces the tube 12, which is connected to the thermostatic element downwards against the resistance of the spring 16 so as to reduce the leakage area. The thermostatic element may be arranged in various ways. It may, for example be flat or curved, it may be arranged below the plunger, the ports may be formed in it instead of in the plunger, and it may carry adjusting- screws.
