Title: Improvements in or relating to foamed inorganic polymers
Inventor: GREY PETER JOHN
IPC: C01B21/092
Filed: 1964-10-09
Abstract: A mass of an inorganic foamed polymer is formed by heating one or more bodies containing an anhydrous phosphorodiamidate metal salt to a temperature such as to partially foam (defined below) the bodies, the bodies being such that foaming may take place throughout their volume, crushing the partially foamed bodies, and heating to a temperature such that further foaming takes place. Partially foamed is defined as a state in which further gas can be evolved on further heating.  The metal salt may be that of an alkali or alkaline earth metal, e.g. Ca or Sr, or Zn, Sn, Cd or La.  The reaction may be carried out in an inert atmosphere, e.g. N2 or NH3.  The Zn salt may be partially and finally foamed at temperatures of 650-800 DEG C. and 750-850 DEG C. respectively, and the Ca and Sr salts partially foamed at 700-850 DEG C. and finally at 850-950 DEG C.  The reactant bodies may contain up to 50% of urea, cyanuric acid, phosphoric triamide, melamine or hexamine. The reactant bodies may be in the form of a thin layer e.g. 0.1 inch thick, or tablets which may also contain 1% of magnesium stearate.  The final heating may be carried out in a surface-graphitized metal container.  Specification 1,070,013 is referred to.

Abstract: 906,652. Frequency measuring. GENERAL ELECTRIC CO. Dec. 23, 1958 [Jan. 30, 1958], No. 41553/58. Class 37. In a system for frequency analysing an input signal from source 1, the signal is added at 3 to the signal already circulating in the closed loop comprising time delay circuit 5, frequencyshifter 9 and band-pass filter 13. Frequencyshifter 9 increases the frequency of the signal in the loop by a constant amount Fs, and the band-pass characteristics of filter 13 are chosen so that a limited number N of circulations is possible. The output of adder 3 has amplitude peaks which occur at regular intervals 1/Fs, the times of occurrence of these peaks on a timebase synchronized to Fs being linearly dependent on the frequency of the input signal. Thus the positions of the peaks 22, 23 on the trace of cathode-ray tube 16 indicate the frequencies present in the input spectrum, the amplitudes of the peaks being proportional to the amplitudes of the respective component frequencies.

Title: Improvements in or relating to pulse communication systems
IPC: H04B17/40
Filed: 1961-11-29
Abstract: 970,736. Testing repeaters in pulse communication systems. WESTERN ELECTRIC CO. Inc. Nov. 29, 1961 [Dec. 20, 1960], No. 42787/61. Heading H4L. Relates to a system for detecting a faulty repeater in a chain of pulse regenerative repeaters and is particularly applicable to bipolar pulse code communication systems in which normally there is only a small direct current component. A test signal consisting of pulse groups in which there are more pulses of one polarity than the other and thus having a direct current component, and having a group repetition frequency which is adjustable and is substantially less than the pulse repetition frequency of the system is generated at the transmitting terminal and each repeater is provided with a filter responsive to a frequency indicative of that repeater. The pulse density of the test signal, and hence the D.C. component, is varied, and the response of the repeater is transmitted back via a return path to indicate the condition of the repeater. In a typical test signal, Fig. 3, line a shows an arrangement of unipolar pulses to provide the D.C. component, line b shows a succession of pulses of alternating polarity combined with the test signal as at c in order to clock the repeaters, and line d shows the " identification tone " resulting from the grouping of the unipolar pulses and having a frequency equal to the group repetition frequency. The test signal is generated at 12, Fig. 4, and applied to the input terminals of the system comprising repeaters 14, 16, 18, 20, 22, each repeater being equipped with a filter 24 to 32, respectively, responding to a frequency f 1  to f 5  peculiar to that repeater. In operation, the repetition rate of the unipolar pulse groups is adjusted to correspond with the frequency allotted to the repeater under test, the test being started with only a small number of unipolar pulses per group which are gradually increased by predetermined amounts to increase the amplitude of the identification tone, with corresponding increase of the D.C. component, until a point is reached at which the amplitude of the identification tone as measured at 13 shows a sharp fall, Fig. 5 (not shown). This gives a measure of the quality of the transmission. A generator for the test signal is described, Fig. 6 (not shown), in which a unipolar pulse train whose density may be varied is first generated and is gated on and off at the required identification tone frequency.

An arresting wire 5 for arresting a landing aeroplane is connected to a brake drum 1, 2 on each side of the runway. To centralize and stabilize the aeroplane the brake drums are connected by a synchronizing wire or chain 6 lying above the runway surface.

A space heating control system having a duct, interiorly and exteriorly of the space, for circulating air, has an electrical heater fed with a cyclic voltage consisting of alternatively occurring peaks of relatively large amplitude and troughs of relatively small amplitude. The cyclic voltage may be derived from a rectifier. A thermostatic switch 26 located in a room energizes an electric heater 22, a fan motor 14 and a control circuit including a thermistor 28 arranged in a budge network and located in an air circulation duct, which below a determined temperature causes transistors 48, 54, 62 to block thus allowing a potential across a resistor 64 to rise and a thyristor 44 to conduct passing current to another heater 24. A capacitor 66 ensures conduction of thyristor 34 near to voltage zeros. The transistors are fed with half waves through a diode 38, a smoothing capacitor 40 and stabilizing Zener diode 41 being provided. The heater 24 may be divided into parts (24a, 24b) see Fig.4 (not shown) one part (24b) being energized through another thyristor (82) conduction of which trails that of thyristor 34 through a circuit (even numbers 94-100).
