Abstract: 722,828. Clinometers. D'ENIS, F. B. Feb. 9, 1953 [Feb. 7, 1952], No. 3310/52. Class 97 (2). In a clinometer of the kind comprising an index member and an indicating scale of which one is rotatable with respect to the other about a horizontal axis and has secured thereto a pendulous mass in the form of a closed container partly filled with a heavy liquid such as mercury, the container is so shaped and dimensioned and contains a sufficient amount of liquid that when at rest the liquid is disposed close to or in contact with a central portion of the top wall of the container leaving unfilled spaces on either side of this central portion, so that upon oscillation of the rotatable element a surge is set up in the heavy liquid having a natural period of oscillation which is less than that of the pendulum system. The clinometer shown has a cylindrical casing 10 with a front transparent cover apertured at 12 and bearing a peripheral scale 15, and a rear wall 13 apertured at 14. A plate 26 bridging the aperture 12 and obscured from view by an opaque cover 27 supports, together with a plate 25 bridging aperture 14, a spindle 16 carrying four equispaced pointers 18. A bracket 19 extending from one pointer has clipped thereto an elongated container 21 partly filled with mercury. The container may be arcuate or V-shaped and may have a bulge 29 (Fig. 5) which is constantly filled with mercury. Preferably the mercury level is tangential to the upper arc of the arcuate container or intersects the upper V of the V-shaped container. A weighted bob 28, Fig. 4 (not shown) may be suspended from the container. In an alternative form, the scale may be connected to the spindle and one or more index marks may be provided on the casing.

IPC: H04L27/26
Filed: 1964-01-30
Abstract: 1,063,032. Data transmission. BRITISH TELECOMMUNICATIONS RESEARCH Ltd. Jan. 26, 1965 [Jan. 30, 1964], No. 4015/64. Heading H4P. In a data transmission system a frequency on each of two data channels represents the combination of Mark and Space pulses which form the first and second pairs of bits of a 4-bit input word. A further channel contains timing pulses, alternate pulses being of different frequency. At the receiver band-pass filters select the three channels, the resultant signals feeding four very high Q tuned circuits in the case of each data channel, and, in the case of the timing channel, two circuits in cascade, each tuned to the geometric mean of the timing signal frequencies. The latter operates a flip-flop which gates open the data channels' tuned circuits for a substantial fraction of each element period so that the oscillations built up in them are quenched prior to the end of each element period, whereby jitter effects are reduced. The eight tuned circuits feed a decoder which translates their output to the original 4-bit signal. Arrangements for detecting loss of carrier and excessively low signal/noise ratio are provided.

Filed: 1959-02-05
Abstract: 864,785. Measuring length. DETECTRON Inc. Feb. 5, 1959, No. 4078/59. Class 40 (1). [Also in Group XXXVI] Apparatus for giving an indication when a void, conductive particle or thin area in dielectric sheet exceeds a given length as the sheet is being advanced, comprises means for generating a voltage pulse having a duration dependent upon the length of each void, conductive particle or thin area in the direction of advancement and means for generating a second voltage pulse having an amplitude corresponding to the duration of the first pulse, the second pulse being fed to an indicator circuit responsive only when the second pulses exceed a predetermined amplitude. In Fig. 1 the dielectric sheet 14 is passed between an earthed roller 10 and one or more wire brushes 12 connected to a voltage source. The circuit to earth will be completed by a metallic particle, by a void of sufficient size to permit a bristle to pass through to the roller or by a smaller void or a thin area if a discharge takes place between the brush and the roller and this will cause the voltage at the grid of a valve 43 to be reduced below the cut-off value for the duration of the void &c. A capacitor 62 will accordingly charge to an amplitude dependent upon the duration of the voltage on the grid and if the capacitor voltage exceeds an adjustable voltage applied to the cathode of a valve 70 this latter valve will conduct, causing valve 96 to become non-conducting and a relay 100 to release. In an alternative embodiment (Fig. 2, not shown), the roller 10 is replaced by a flat conducting sheet and it is also suggested that where a number of brushes are used across the width of the dielectric sheet the brushes may be connected to different indicating circuits.
