Title: Improvements in or relating to telephone signalling systems
Inventor: WRIGHT ESMOND PHILIP GOODWIN
IPC: H04Q11/04
Filed: 1963-03-08
Abstract: 1,040,833. Automatic exchange systems. STANDARD TELEPHONES & CABLES Ltd. March 6, 1964 [March 8, 1963], No. 9305/63. Heading H4K. In an inter-exchange system information relating to a call is sent over signalling circuits to the wanted exchange, whereupon an independent message channel is established backwardly from the called exchange over the most direct route available, which is not necessarily that of the signalling circuits. On a call from A to D, for example, signals may pass by way of B and C, although the preferred message channel is direct from A to D. The signals are first given a number identifying the call, but after a message channel has been assigned the subsequent supervisory signals are given a number identifying the channel. The signals are recorded at each exchange on buffer stores and are processed by a routing control circuit. The invention is suitable for use in a system operating on the TAS1 principle. The system may employ a communication satellite in association with exchanges at a number of ground stations.

Abstract: 812,757. Coiling fins on tubes; rolling. CARRIER CORPORATION. March 28, 1956 [March 31, 1955], No. 9726/56. Classes 83 (2) and 83 (4). Apparatus for winding a sheet metal ribbon about a tube to form a helical fin thereon comprises ribbon-engaging means adapted differentially to elongate a ribbon fed thereto and cause the emerging ribbon to curl, means for directing the curling ribbon helically around and edgewise to the surface of the tube and rotary means which determine the helical lie of the finforming ribbon about the tube and cause its inner edge to grip and impart rotational movement to the tube. The metal ribbon passes from a supply through a guide 111, adjustably mounted on a cover 67 fixed to the end of a housing 20 on a frame 10, to co-operating driven forming rolls 61, 74 which differentially elongate the ribbon to form it into a helix and also form a slight tube engaging foot thereon. One or both the rolls may be convexly curved to give the ribbon a dished form. The roller 61 is secured to the end of a hollow shaft 33 rotated, and axially adjustable, by a threaded member 37, in the housing 20, through which shaft 33 the tube, on to which the fin is coiled, is guided. The roller 74 is mounted in an inclined extension 24 of the housing 20 and is driven from the hollow shaft 33 through bevel gears 36, 71. The helically-formed ribbon is guided about the tube by a U- shaped guide 112, Figs. 14, 27, embracing the tube and secured to the cover 67. A rotating disc assembly 117 then engages the fin on the the tube to elongate its outer edge to cause it to grip the tube and rotate it and move it longitudinally, transmitting rotation from the disc assembly 117. The discs also space the turns of the fin and determine its final pitch. The disc assembly 117 comprises a series of axially spaced discs 118 on a shaft 119 rotatable in a bracket 136 adjustably mounted on the frame 10, the axis of the discs being inclined to the axis of the tube. The discs 118 may be formed on the outer parts one or both sides with radial ridges 121 and grooves 122, Fig. 20, which form undulations in the fin edge which are flattened out as the fin leaves the nip between adjacent discs. The shaft 119 is driven through a coupling 147 from a stub shaft 90 mounted in the housing extension 24 and driven by a chain 92 from the roller 74. The face of the roller 61 may be formed of a series of interconnected plane surfaces. A fin of varying height may be formed when the tube is afterwards to be bent. A plurality of strips may be coiled simultaneoulsly.

Title: Improvements in or relating to radar simulation
Inventor: CUTLER ALBERT ERNEST
IPC: G01S7/40
Filed: 1960-03-18
Abstract: 887,641. Radar simulators. COMMUNICATIONS PATENTS Ltd. March 18, 1960, No. 9783/60. Class 40(7). A radar simulator comprising means for generating successive signal trains of timespaced signal elements corresponding to echoes from the earth surface includes a "shadow" amplifier which causes a first signal element in a wave train to reduce the amplitude of succeeding signal elements in dependence on the amplitude and duration of the first signal element to simulate the screening effect of foreground objects on background objects. The invention is described as applied to simulating a craftborne scanning radar in which a model or transparency 10, Fig. 1, representing the earth's surface is scanned by a flying-spot C.R.T. 11 and a photo-cell 13 whose output is applied through the "shadow" amplifier 20 and a mixer 21 to modulate the intensity of a display C.R.T. 22 scanned synchronously with the flying-spot scanner 11. The photo-electric scanning device is moved relative to the transparency 10 to simulate movement of the craft by means of orthogonal lead screws 15, 16 and signals simulating other craft, noise and clutter are applied to the mixer 21 from generators 61, 62, 63. The "shadow" amplifier 20 is shown in Fig. 2. Positive video signals from the photocell 13 are applied to the control grid. of a pentode 25 via an integrating circuit 30, 31 of time constant 2 Á-secs. which discriminates against short duration signals, e.g. signals simulating marker buoys, and the negative output from the pentode 25 is applied toa cathode-follower 33 having a C.R. cathode circuit 36, 35 having a time constant of the same order as the sweep trace so that a signal of large amplitude and duration will produce a delayed negative control voltage. This control voltage is mixed in the grid circuit of a pentode 41 with the positive video signal from the photo-cell 13 thereby reducing the amplitude of subsequent video signal elements. Alternatively the control signal may control the gain of the pentode 41. The resultant output from the pentode 41 is applied to an output phase inverter 47 via a diode 52 having an adjustable positive bias which removes any pedestal produced in the pentode 41. The degree of "shadowing" is controlled by potentiometers 29 and 35. At the end of each range sweep the capacitor 36 is discharged by a clamping circuit (not shown) controlled by the master time base. In order to simulate the "shadowing" effect on echoes from other craft, such signals from the generator 61 may be applied to the pentode 41.

Finely divided SiO 2  is produced by simultaneously adding solutions of alkali metal silicate and a mineral acid to water at 70-90 C. while maintaining a pH of 7-9, until a SiO 2  concentration of 2À5-5À0% has been reached, and then acidifying the mixture to a pH below 4, and separating, washing, and drying the SiO 2  formed. The ratio of addition of acid (Fz) and of silicate (Fw) and the time of reaction (t) are determined from equations relating concentration of acid (Cz) and silicate (Cw), quantity of water (V), and final SiO 2  concentration (Cs); and are controlled such that lies within a 3-dimensional diagram relating Cs, pH, and TC. (Fig. 7). Na or k silicate may be used, e.g. waterglass with a SiO 2 /Na 2 O ratio of 3À3/1 and a SiO 2  concentration of 6-27%. The acid may be 5-25% H 2 SO 4 . Acidification, e.g. to pH below 4, may be effected by adding acid at a faster rate, or by running the reaction mixture into acid. The SiO 2  may be washed to a Na 2 O content below 1%, and dried at 130- 150 C. for 10-20 hours, or in an atomization drier with inlet and exit temperatures of 500 and 125 C. respectively.
