Patent GB-1253895-A (GB)
Title: Improvements in or relating to aircraft landing radio guidance receivers
Inventor: BENJAMIN JOHN
IPC: G01S1/02
Filed: 1969-05-09
Abstract: 1,253,895. Radio navigation. DEFENCE, SECRETARY OF STATE FOR. 4 May, 1970 [9 May, 1969], No. 23734/69. Heading H4D. A receiver for aircraft landing guidance of the kind in which two double-sideband signals yield relative amplitudes which are a measure of the departure of the receiver from the preferred approach path includes multipliers 5, 6 for deriving beat frequencies from combinations of upper and lower sideband components respectively and a comparator 9 for indicating discrepancy between the beat frequencies. In the usual I.L.S. system 90 Hz and 150 Hz modulations are derived from and phase-locked to a common 30 Hz source and the sum of 90 Hz and 150 Hz modulation depths is substantially constant in the guidance area; hence a phasesensitive detector 9, in the absence of reflections, will produce no output or a small and steady D.C. In the presence of reflections it is demonstrated that the output of detector 9 will fluctuate; circuit 10 and device 11 afford a warning when a predetermined fluctuation is exceeded.

Abstract: 245,510. British Colour Printing Co., Ltd., and French, W. J. Oct. 8, 1924. Show cards; figures or models.-Relates to advertising or display devices of the kind in which a piece of glossy and usually transparent material, such as celluloid, is provided on or used in conjunction with a cord, sheet or backing having a pictorial representation or coloured surface, the glossy material being intended to impart a more realistic appearance to what is displayed than by a pictorial representation alone. According to the invention, the glossy material is embossed or otherwise treated to produce raised parts or a surface in relief for representing the pattern, shape, configuration or ornamentation on or of the article or part to be portrayed. In the application to a card a, Fig. 1, having a picture of a bowl containing biscuits, the card is embossed at b around the portion representing the bowl. Within the outline b a piece of celluloid c, cut to shape, is placed and secured to the card a, preferably by means of a " cutter crusher." The celluloid is previously embossed or otherwise treated to produce a surface pattern in relief representing cutting or moulding around the bowl and the shape of the stem and base. As shown in Fig. 4, the embossed celluloid g is placed between a backing d having a picture of a cobra, and a front piece e having an aperture f shaped to the outline of the picture on the backing. The celluloid is embossed to represent the scales of the cobra. In a modification, Fig. 5, the display device represents a person h holding a tray i bearing a glass of beer. The glass is formed by bending a strip of embossed celluloid j fixed at one end and having at the other a tab k which is inserted under the fixed end. The celluloid is used in conjunction with a backing l of paper coloured to represent the colour of beer.

Abstract: 983,618. Telegraphy. SIEMENS &HALSKE A.G. June 19, 1963 [June 20, 1962], No. 24343/63. Heading H4P. The invention provides an apparatus for receiving signals at one speed and for re-transmitting them at another speed or the same speed. It comprises input and output stores and is characterized in that a character is passed from one store to the other only during the stop pulse of that character. Received signals from l1 are fed via unit EE, where the start and stop bits are removed, to input store ESp. From this store characters are transferred to output store ASp, either direct or via tape store BSp. Store ASp is read out at a selected speed, signals passing via unit AE, where start and stop bits are replaced, to line 12. The manner of operation depends upon the relative speeds of the signals on l1 and 12; (a) If the speed of 11 is the greater, stored ASp and ESp will gradually fill to capacity. When ASp reaches 120 bits switch k1 is opened. Subsequent received characters are now transferred to tape store BSp whenever the input store is filled to 120 bits, transference taking place in blocks of 120 bits. Output store ASp has a main capacity of 120 bits and a reserve capacity of 90 bits. If k1 is open, whenever the total unfilled capacity of the store becomes 120 bits a block of that length is transferred from the tape to the store for subsequent transmission. Switch k1 is closed again only when there is no data in the tape store. (b) If the speed of l2 is greater than that of l1, k1 remains closed and characters are transferred between the input and output stores during the stop bit, as determined by counter FZ1.
