Title: Improvements in and relating to radio locating equipment
IPC: G01S13/42
Filed: 1946-10-22
Abstract: 634,992. Radiolocation. BRITISH THOMSON-HOUSTON CO., Ltd. (General Electric Co.). Oct. 22, 1946, No. 31382. Drawings to Specification. [Class 40 (vii)] In a pulse radar system comprising a directive aerial system which performs a conical scan about a mean axis so that echo signals from targets off the mean axis bear a modulation at the scanning frequency, means are provided for producing on a cathode-ray tube a circular timebase synchronized with the modulation and for applying a brightening signal to the grid of the cathode-ray tube at a predetermined epoch of the aerial scanning cycle. An oscillatory voltage whose amplitude is inversely proportional to the range of the target is applied to the horizontal plates of the cathode-ray tube to provide the indication with " wings." The radius of the time-base is proportional to the degree of misalignment between the target and the mean axis so that the display accordingly provides an indication both of the range of the target and of the direction and the extent of its deviation from the mean axis. The display is similar to that which would be seen in a telescope mounted parallel to the mean axes of the aerial system. Echo signals received by the directive aerial system are applied to a mixer device to which is also applied a train of rangegate pulses. These pulses are set either manually or automatically into coincidence with the selected echo signals which are then passed to an integrating network and a resistance-capacity filter circuit tuned to the aerial scanning frequency. The output of the filter is applied through an amplifier to one pair of plates of the cathode-ray tube and also through a 90 degree phase-shifting network and a further amplifier to the other set of plates to deflect the cathode-ray beam in a circular path. The motor driving the aerial in its scanning motion is coupled to a generator which generates a signal at the frequency of the aerial scan. This signal is applied to a " clipping " valve and thence to a differentiating network and to a flip-flop which generates, at a predetermined epoch of the aerial scanning cycle, a positive pulse which is applied to the grid of the cathoderay tube to turn the electron beam on to cause illumination of a portion of the circular timebase. To provide the indication with " wings " the output of a high-frequency oscillator is applied to a potentiometer which is controlled from the range-gate control, so that it delivers a signal whose amplitude is inversely proportional to the range setting of the gate circuit.

Abstract: 445,407. Casting concrete walls in situ. McMAHON, C. J., Coogee, Teignmouth, Devon. Nov. 13, 1935, No. 31470. [Class 20 (ii)] A movable mould comprising side plates and an end plate for use in moulding monolithic walls in situ, has means for locking the side plates in position, reverse movement of these means causing the side plates to be released both from the east wall and from the end plate. The side plates a are provided with cam surfaces 3 which coact with counterweighted levers k whereby rotation of these levers causes the mould sides to grip the wall portion previously cast. Reverse rotation of these levers releases the mould sides, and to ensure separation, inclined tails n of angle bars m attached to these levers engage bars o on the mould sides and press the sides away from the wall; at the same time a two-part shaft s which carries pins w engaging cam grooves x provided on brackets t on the rear plate, is rotated, thus causing shoulders s<1> on the shaft to press against the inside surfaces of the mould sides and release them from the rear plate. The shaft s is rotated through link gear r, q, p from the locking levers k. A roller 11 is provided on the rear plate to facilitate movement of the mould. A removable front plate f can be hooked to the side plates when required and the rear plate carries a core e for use when constructing hollow walls. Angle extensions adapted to be secured to the front end of the mould are used for constructing corners.
