Title: Electron beam tube cooled partially by direct radiation
Inventor: ANDORE PERETEIE
IPC: H01J23/033
Filed: 1990-01-04
Abstract: PURPOSE: To enable a good cooling without enlarging a size of constitution, by providing a plurality of fins facing a required direction in an external wall of a collector, and performing cooling by direct heat radiation. CONSTITUTION: In an external wall 5 of a collector tube 1 or the like in a cylindrical electron beam tube having a vertical axis YY', in parallel thereto, in a direction such as crossing with the axis YY', a plurality of radial fins 4 are provided. Heat generated in a collector or the like, after transmitted in the fin 4, is radiated to a cooling heat source side by direct heat radiation. By utilizing this direct heat radiation, without enlarging a size of the constitution, the collector or the like can be well cooled. Further, a similar effect is obtained even when partly the fin is directed to a direction not crossing with the axis YY' but in parallel thereto.

Title: Methods of and systems for the demodulation of a wave which is repetitive at equal known time intervals
IPC: H03K9/00
Filed: 1941-01-17
Abstract: 586,115. Directive wireless signalling. STANDARD TELEPHONES & CABLES, Ltd., and EARP, C. W. Jan. 17, 1941, No. 652. [Class 40 (v)] In systems for obstacle detection by radio pulses or by the frequency sweep method using a wave modulated by a signal wave which is repetitive in character, a favourable signal-tonoise ratio is obtained by feeding to a differential detector, the signal wave and a suitable comparison wave, thus eliminating random noise elements. Fig. 1A shows a receiver for use with the radio pulse system in which the detected signal is applied to one input T of a differential detector D, the comparison wave being fed in at T1. The output is taken from a low-pass filter LP. The comparison wave-is supplied by a generator S at pulse periodicity and is shaped by passage through a phase shifter PS, limiter L, high-pass filter F and half-wave rectifier R. Fig. 1B shows the frequency sweep system in which energy direct from the transmitter T whose frequency is varied cyclically over a predetermined frequency range, is made to beat with a reflected wave in the receiver detector Det. 1, the result after further detection at Det. 2 comprising the principal wave for feeding at A to one input of a differential detector as in Fig. 1A. The comparison wave is derived from the modulator M of the transmitter and is shaped by a network N before being applied at B to the second input of the differential detector. In a modification, the comparison wave is derived from the signal wave by passing it through a network which delays it for an integral number of pulse periods. In a further modification, the comparison wave is derived from the main wave by modulating it from a constant frequency source, the modulated wave being mixed in proper phase with the signal wave in a second modulator. Specification 578,114 is referred to.

Title: Improvements in or relating to modulated carrier-wave transmitters
IPC: H03C1/62
Filed: 1936-01-08
Abstract: 468,756. Wireless transmitting systems. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and GREEN, E. Jan. 8, 1936, No. 709. [Class 40 (v)] In a series modulating arrangement in which the carrier frequency source R, consisting of a valve or bank of valves, is connected in series with and on the negative side of a modulating valve stage M, the grid voltage applied to the input of the modulating valve includes a fixed bias component and, in opposition to it, a component across a resistance R3 obtained by rectifying, at S, the modulated carrier energy. The arrangement is such that in the absence of modulating signals at G the fixed bias V2 applied across resistance R2 is effective to "back off " the valve M, but on the occurrence of modulating signals the total bias is reduced by the increase of the voltage across R3 and the feed current through the valve stage M is increased. The bias voltage V2 may be obtained from the H.T. supply by connecting a high resistance between the negative terminal of the supply and the junction point of resistances Rl and R2. In a modification, Fig. 3, the modulating stage consists of a bank of two valves M1, M2 in parallel. Their grids are connected to tappings on resistances R1<1>, R1<11> which are connected through condensers to the modulating source G and to tappings on resistance R2, which is coneected to the negative H.T. lead (earth) through a high resistance R5 giving the fixed bias potential. The rectified modulated carrier is applied ; after smoothing across the resistance R3 and the free terminal of the modulating source G is connected to the tapping on resistance R2 to which resistance R1<11> is connected. The Provisional Specification discloses an arrangement in which the carrier stage is on the positive side of the modulating stage and also an arrangement for obtaining fixed bias in the grid circuit of the modulating stage of a series modulation arrangement. In the latter arrangement, a high resistance in the grid circuit is connected in series with a further high resistance across the carrier stage and is shunted by a condenser sufficiently large to byepass all modulating frequencies. Specification 427,026 is referred to.
