Title: Improvements in or relating to the protection of control arrangements from undesired or stray electromagnetic radiation
IPC: G21D3/04
Filed: 1964-10-27
Abstract: 1,070,500. Controlling reactors. SIEMENS A.G. Oct. 27, 1964 [Oct. 31, 1963], No. 43853/64. Heading G6C. In a reactor safety control system the parameter measuring devices within the reactor are coupled to the reactivity control means through signalling channels. The latter are exposed to radiation which generates signals in the electric circuits which are capable of causing operation of the safety control means in the absence of any signals from the parameter measuring devices, i.e. under normal operating conditions. To prevent this effect, a dummy channel and electric circuit is disposed adjacent to the active channel and is therefore subjected to the same radiation intensity. The leads in the two channels are coupled in opposition at the control device and the resultant signal due to the incident radiation is thus zero.

Abstract: 1, 046, 819. Automatic control systems for cathodic protection. RUMANIA, MINISTERUL INDUSTRIEI PETROLULUI SI CHIMIEI. Oct. 29, 1964 [Oct. 30, 1963], No. 44149/64. Heading G3R. In a cathodic protection system, a control circuit is arranged to produce current pulses the mark/space ratio of which is controlled in dependence upon an error signal obtained by comparing the potential of a sensing electrode with a reference voltage derived from a Zener diode. These pulses are applied over a transistorised amplifier and an integrating stage to a sacrificial anode associated with the structure being protected. The protecting current is thus automatically controlled so that the potential detected by the sensing electrode is maintained at the reference value. Suitable arrangements of oscillators, amplifiers and trigger circuits for producing the pulses are described with reference to Figs. 2, 5 and 6 (not shown) which illustrate, in block diagram form, three different embodiments.

Abstract: 935,958. Releasable fastenings. APPLICATIONS INDUSTRIES DU TUBE S.A. Dec. 29, 1960 [Jan. 5, 1960], No. 44638/60. Class 44. In a fastening arrangement for securing together two tubes which are telescopically adjustable relative to each other, particularly where said tubes form the support for a small table, tray, or seat 2, the outer tube 3 is provided with grooves 5 on its internal surface which co-operate with grooves on the outer surfaces of a plurality of members 16 supported adjacent the lower end of the inner tube 6. The said members 16 are held by means of an elastic, annular member 17 between the lower, frusto-conical end of the inner tube 6 and a frusto-conical member 15 fixed on a tubular member 12 which is rigidly connected to a further tube 8, the two tubes 8, 12 being slidable along a fixed rod 20, and normally being urged upwards by a spring 14. Thus normally, as a result of the action of the spring 14, the members 16 are compressed between the lower end 7 of the tube 6 and the member 15, and are therefore urged outwardly to firmly engage the grooved outer tube 3. In order to release the fastening and adjust the relative positions of the two tubes 3, 6, the tubes 8, 12 are forced downwardly by raising the lever 10, thus lowering the member 15 relative to the lower end 7 of the inner tube 6 and enabling the members 16 to contract away from the outer tube 3, under the action of the elastic member 17.

Title: A process for producing a substantially monocrystalline rod of semiconductor material
IPC: H01L21/208
Filed: 1963-11-18
Abstract: A monocrystalline rod of silicon having a diameter of at least 25 mm. is pulled from a molten zone produced by induction heating of the upper end of a rod of larger diameter.  The ratio of the diameters of the thicker and thinner rods is preferably greater than 1.4.  The molten zone may be initially produced by induction heating or electron bombardment.  The larger diameter rod may be preheated by resistance or induction heating or by being surrounded by a silver heat reflector in the form of a cylinder having a vertical slit to prevent coupling.  Pulling may be in a vacuum or protective gas atmosphere.  The crystal being pulled may be rotated at 10-150 rpm. The melt may be replenished by adding powdered or liquid material or by further melting the rod.  In the latter case, the thicker rod may be raised or the induction coil lowered as pulling proceeds. According to Fig. 3, (not shown) a rod 23 is pulled from a melt 21 maintained molten by an induction coil 22 in a cup-like depression in a larger diameter rod 20, molten material being supplied to the molten zone through a slip 24 by melting of a rod 26 by an induction coil 25.  According to Fig. 4 (not shown) the melt is replenished by melting the rim of the cup-like depression by an induction coil 34.

Filed: 1973-09-28
Abstract: 1444810 Frequency modulation; preventing acoustic reaction; signal compression ITT INDUSTRIES Inc 28 Sept 1973 [7 Oct 1972] 45525/73 Headings H3R H3J and H4R In a method of varying the frequency of an input signal in dependence on a control signal, the signal to be varied is delayed by an electronic analogue delay line having a delay determined by the frequency of a clock signal, the clock signal being frequency modulated by the control signal. If the control signal is of triangular waveform, frequency-shift keying of the input signal is acheived because during the leading edge of the triangular wave, the frequencies of the input signal are shifted up in frequency, and during the trailing edge they are shifted down in frequency. If a sawtooth control signal is used, a frequency shift in one direction is achieved. Such an arrangement may be utilized to illuminate acoustic feedback when a microphone and loud-speaker are used in close proximity. Alternatively, the control signal may consist of a band of frequencies having an arbitarily chosen frequency distribution. If the frequency variation is made sufficiently large, a speech signal input may be rendered unintelligible, or encoded.
