Filed: 1970-06-24
Abstract: 1317972 Pipe supports G A FORBES 19 April 1971 [24 June 1970] 30551/70 Heading F2P A support for a pipe 3 comprises an apertured body 1 of thermally insulating material, e.g. cork, and a shell 6 formed with a flat base portion 4 for standing the support on a flat surface, e.g. the upper surface of a length of angle iron 5.

Title: Radar systems
IPC: G01S13/42
Filed: 1971-05-01
Abstract: 1319002 Pulse radar; aerials MARCONI CO Ltd 23 Feb 1972 [1 May 1971] 12570/71 Headings H4A and H4D A within-pulse scanning radar system has a transmission aerial arrangement providing a fan-shaped beam which scans in elevation such that its movement is slower at low than at high elevations. As described, a vertical array of horns T 1  to T 2 , Fig. 2, provides a beam which is narrow in a vertical plane (e.g., 1À2 degrees between half-power points) but which has an azimuthal angle equal to the surveillance angle required. A transmission pulse generation circuit TG coupled to a master oscillator MO feeds pulses to the aerial elements T 1  to T 2  via a scanning arrangement ST, which introduces equal increments of phase change between said elements in accordance with the desired scanning rate. A receiving aerial arrangement comprises a horizontal array of horns A 1  to A n  which provides a beam which is narrow in azimuth but which extends in elevation over the surveillance angle required. Each aerial element A 1  to A n  is associated with a respective amplifier/frequency changing mixer F 1  to F n  which has a second input from a respective local oscillator LO 1  to LO n  controlled by the master oscillator MO. Within pulse scanning is effected by providing a progressive frequency difference of 1/t between successive local oscillators, where t is the pulse duration (e.g., 2À5 micro-seconds). Thus, if the frequency of the local oscillator associated with the central aerial element is f 0 , those of the local oscillators for the elements on either side would be f 0  + 1/t, for the next pair f 0  + 2/t, and so on. Each unit F 1  to F n  feeds into a respective storage filter S 1  to S n  having a bandwidth of 1/t and connected to a utilization line U. Both range and direction are determined in quantized form. As shown in Fig. 3, the transmission beam may be scanned from maximum elevation to zero elevation in steps having decreasing speeds and pulse repetition frequencies (P.R.Fs.) and with maximum dwell at the end of the scan. The beam may be stepped back by a beamwidth at each change of P.R.F., it being arranged that signals received during these steps are ignored by the processing equipment. Instead of stepping back the scanning, Gaussian loading of the receiver sensitivity may be employed at each change of P.R.F.

Holes 30 may be provided in the collar to permit extra cables to be carried. When these holes are not carrying cables pins 33 made of, for example polytetrafluoroethylene, are inserted to prevent the collar distorting when clamped.

Abstract: 1346987 Casting processes BRITISH STEEL CORP 28 May 1971 [26 March 1970] 14681/70 Heading B3F A method of casting rimming steel ingots comprises pouring rimming steel into a mould, allowing the steel to form an outer solid skin and a pin zone, infecting a deoxidizer into the top zone of the cast ingot to kill the rimming action in only the top zone, force-cooling the top of the ingot to form a solid cap and allowing the rimming action to continue in the lower part of the ingot so that pressure resulting from gas evolution causes the solid cap to become convex. "Fish-tailing" is thereby minimized on subsequent rolling of the ingot. The deoxidizer is preferably aluminium introduced into the ingot as a continuous strip, rod or wire or as shot.

Abstract: 1355389 Telegraphy; loss of signal detection KOMBINAT VEB MESSGERATEWERK ZWONITZ GERATEWERK KARL-MARXSTADT 8 Dec 1971 57054/71 Addition to 1325470 Heading H4P In an arrangement as disclosed in the Specification 1,325,470 for detecting loss of signal input and providing a fault indication to disconnect a receiver, the differentiating element and bi-stable multivibrator are replaced by a Darlington pair of transistors. This enables use on single or double current operation without alteration and enables fault lasting over 130 ms. when operating at 50 baud to be clearly detected. Capacitor C is normally charged through resistors W2, W5 and on reception of a stop element discharges through the collector emitter path of the transistor T2 hence with normal start-stop code the capacitor will be regularly discharged on reception of each stop element i.e. at least once every 130 ms., discharge current being limited by resistor W5. In the event of loss of input, capacitor C will not be discharged and the yoltage will build up to exceed the threshold value of Zener diode D2 thus sending another transistor T3 conductive, resulting in a lamp 2a being energized and a signal through W7 switching off the equipment 1, normally a teleprinter.
