Title: Converter for catv
IPC: H04N7/167
Filed: 1973-05-14
Abstract: 1430848 Television distribution systems OPTICAL SYSTEMS CORP 14 May 1973 [16 May 1972] 22800/73 Heading H4R In a television distribution system, a converter for rendering a TV signal intelligible to a receiver is enabled when a transmitted digital code matches a digital code generated, e.g. by switches or a punched or magnetic card in the converter. At the transmitter, TV vertical and horizontal sync. pulses are manipulated (Fig. 3, not shown) and gated to produce clock tone bursts of 18À9 kHz and coded data bursts of 23À6 kHz having trapezoidal envelopes. A 16-bit code following a 28 msec. start/sync. tone burst is representative of the class of subscriber in relation to the programme. The clock and coded data is added to an audio modulator and both video and audio scrambled before transmission. At the converter, Fig. 5, switch 88 applies power and connects the distribution cable to the circuitry 94-110 which includes a splitter 96 to divert RF signals to age circuitry (Fig. 6, not shown) which heterodynes the RF to IF and extracts descrambling data to enable the descrambling RF amplifier 100 and extracts the 18À9 kHz clock and 23À6 kHz data signals for use in a comparator (Fig. 7, not shown). Here, the clock signals are squared to cycle a 16-bit counter to sequence an 8 x 8 matrix optical card reader on the occurrence of the start tone burst fed to a sync. generator. The coded data from the IF circuit (Fig. 6) and from the card reader is compared in an Exclusive-OR gate (162) to maintain oscillator 106 in the heterodyne mixer 104, Fig. 5 converting the transmitted TV band to a usable band. The enabling signal is held for up to ten successive data sequences to enable different types of coded data to be transmitted and to prevent disablement during short transmission breaks. The card reader may be replaced by a switch matrix set according to prior instructions. The reader may however include TV channel encoded data which enables a varacter to tune a mixer oscillator to automatically convert the TV signals to the corresponding TV channel for the receiver. Alternatively a cyclical ramp generator may be held at the appropriate level on receipt of a transmitted holding code at an instant appropriate to tune the oscillator. Increased security may be obtained by arranging for the card reader to have a switch plan altering the card data readout order.

Title: Improvements in and relating to take-off indicators for aircraft
Inventor: BROWN ALEXANDER ANDERSON
IPC: G05D1/00
Filed: 1958-07-18
Abstract: 866,228. Aircraft take-off indicators. KELVIN & HUGHES Ltd. July 20, 1959 [July 18, 1958], No. 23201/58. Class 40 (1). An aircraft take-off indicator for showing distance travelled in relation to distance to go, in which a voltage is generated by the rotation of an undercarriage wheel, the magnitude of the voltage being proportional to the ground speed of the aircraft, has means for correction for the change in effective diameter of the wheel with change in load on the tyre as the aircraft lifts. An electromagnetic generator 10 (Fig. 1) operated by the undercarriage wheel gives a voltage dS/dt . The undercarriage also operates an ex-   tension sensor 11 to give a voltage which is fed dS together with - into a correcting unit 12. The dt output from the correcting unit 12 is passed through an integrator 13 to give an output S representative of the distance travelled. The output S is then fed into a subtracting unit 14 together with a preset voltage Sa, from a source 15, which is representative of the total runway length. The voltage Sa-S is then shown on the indicator 16 as " distance to go." The output from the correcting unit 12 is also passed through a differentiating unit 19 to give an output A representative of the instantaneous acceleration. This is fed into a subtracting unit 18 together with the output At from an acceleration/time programme unit 17 which represents the minimum required acceleration at that instant in order to take off in the " distance to go." The " excess acceleration " A-At is shown on an indicator 20. The programme unit and the differentiating unit may have mechanical outputs.

Filed: 1922-09-01
Abstract: 186,595. Metropolitan-Vickers Electrical Co., Ltd., (Assignees of Hodgkinson, F.). Sept. 30, 1921, [Convention date]. Fluid bearings.-A film of lubricant is established betwen the contacting surfaces of a bearing prior to their relative rotation by supplying lubricant therebetween at a number of points at pressures proportional to the bearing pressures adjacent to such points in order to prevent injury which is liable to be caused when a member commences to rotate in a dry bearing. The stationary surface 10 of a journal bearing is provided with a number of separate grooves 11 arranged symmetrically about the axis. Lubricant is supplied to the grooves from a pump 14 through a pipe 13 and branches 16. Each branch 16 communicates with a grooves 11 through a small aperture 17, which serves to reduce the pressure. The lubricant in the groove where the bearing pressure is large is not able to pass readily between the bearing-surfaces, with the result that the pressure of lubricant in such a groove increases and approaches the pressure in the pipes 16, while the pressure of lubricant is smaller in a groove where the bearing pressure is small. In a modification, each groove 11 is supplied from a separate pump. The applications of the invention to an ordinary thrust bearing and to a Michell thrust bearing are also described.
