Abstract: 1,145,955. Gravity switches. LONDON BANKSIDE PRODUCTS Ltd. 20 Feb., 1968 [22 Feb., 1967], No. 8471/67. Heading H1N. In a switch actuated by tilting, the actuating member is independent of the contacts so that contact pressure is unaffected by the angle of tilt. A ball 4 is free to roll in a closed tubular member 3 pivoted on a projection 2 on the base 1, so that the member 3 is unstable except in its two limiting positions where it abuts against stops 5, 6. Thus, when the base 1 is tilted, the member 3 will, at a certain point in the movement, turn rapidly to its alternative stable position. The spindle, to which it is fixed, has a flat 12 across it, adjacent to a spring blade 7, so that when the member 3 turns to abut the stop 6, the blade 7 is lowered to allow contacts 9, 10 to close. The pivot of the member 3 is slightly to the right of the mid-point, as seen in the figure, so that when returning to the position shown, the ball 4 has a greater moment to enable it to overcome the downward thrust of the spring 7.

Abstract: 689,821. Colour television. HAZELTINE CORPORATION. April 13, 1951 [May 25, 1950], No. 8674/51. Drawings to Specification. Class 40 (iii). In a dot-sequential colour television system, i.e. a system wherein signals corresponding to component colours of a televised image are cyclically sampled at a high rate (e.g. 3.8 Mc/s.), a " monochrome signal resulting from the algebraic combination of the colour component signals is derived, and at least the low-frequency components of this signal are conveyed to the final output at the transmitter and to the reproducer at the receiver, by channels which by-pass the sampling devices effecting respectively the multiplexing of the colour-component signals and the demodulation of the multiplexed signal and extraction of colour information therefrom, the output from the sampling device at the transmitter being restricted in frequency to induce only those components resulting from the modulation of the sampling frequency by the colour component signals. This results in a composite picture signal wherein all the brightness information is conveyed by the "monochrome " signal and the multiplexed colour component signals may, if desired, be restricted to a narrow frequency band so that the picture " drawn " by the " monochrome " signal appears as if " painted in " by the colour signal. By varying the gain at the receiver of the channel conveying the colour signal, the colour saturation in the reproduced picture may be controlled. In a preferred embodiment, Figs. 1 and 2 (not shown), the frequency band of the monochrome signal, produced by combining the three separate colour outputs of the colour camera, in parallel, is 0-4 Mc/s. The individual colour-component signals are each restricted to 0-2 Mc/s., being transmitted, in combination with the monochrome signals, as the 2-4 Mc/s. frequency band resulting from heterodyning the 0-2 Mc/s. colour signals with the sampling frequency in the sampling device. In an alternative arrangement, Figs. 1a, 2a (not shown), the portion of the monochrome signal sent by the by-passing channel is restricted to 0-2 Mc/s., the remainder of the monochrome signal being combined with the colour-component signal in the multiplexed channel. In further modifications, the frequency band of the colour signals is restricted further, the green and red components occupying a band of 0- 0.5 Mc/s. while the blue component occupies a frequency band of 0-0.1 Mc/s.
