Title: Spectrometer system
IPC: G01T1/36
Filed: 1973-01-18
Abstract: 1385152 Radiation spectrometers INTERTECHNIQUE 18 Jan 1973 [19 Jan 1972] 2753/73 Heading G1A A spectrometer system for counting e.g. gamma rays emitted by n different radioisotopes in samples, includes a first linear amplifier 20 and second amplification means e.g. 22-26 comprising a cascaded series of linear amplifier stages, together with n counting channels, each having a counting means e.g. 34-38; a pulse height analyzer e.g. 28-32 passing only a selected amplitude range of pulses to the counter, and having means for manually adjusting said range; and separate operator controlled selector means e.g. 40-44 to connect the analyzer to the output of the first amplifier or of any one of the stages of the second amplification means. In the Fig. 1 system, the sample is monitored by two scintillation counters, coupled to summation circuit 16, but, alternatively, a single crystal into a hole in which the sample is lowered, may be viewed by a single or two photo-multipliers. Fig. 1, and Fig. 2, more clearly, show the selector means, e.g. 40, having connections to outputs 48, 50, 52 and 54 of the amplifiers 20, 22, 24, 26. An arm 46 is used to select the output to be used. In the positions of to k, an arm 56, actuated in synchronism with arm 46, connects the output of amplifier 50 to respective amplitude windows which have been preset by adjustment of pairs of screws 62, 63; 64, 65 etc. When the selector positions b to c are used, the windows may be manually adjusted by dials 78, 79. The amplifiers of the second amplification means are of equal gain when four are used, these may all have gains of 2. Alternatively, two amplifiers with a gain of 2 and one with a gain of 4 may be used. Recalibration of the system is carried out by use of a standard isotope having a well-defined peak, and alteration of the high voltage supply 18 to attain maximum counting efficiency. A modification for use in position counting uses auxiliary coincidence circuitry, Fig. 4 (not shown).

Title: Radar apparatus
IPC: G01S13/64
Filed: 1964-01-22
Abstract: 1384686 Radar EMI Ltd 14 Jan 1965 [22 Jan 1964] 2864/64 Heading H4D In a pulse radar system for the detection of moving targets the echo signals are received by storage media, e.g. storage tubes. Each storage tube has the echo signals after coherent detection written on it in a series of intensity modulated vertical lines, one line corresponding to each pulse. Due to the Doppler shift introduced into the reflected signals by the target motion, the charge pattern of the vertical lines on the storage tube has an increased intensity at the point along the lines representative of the moving target range. The array of vertical lines is scanned successively along different horizontal lines each of which corresponds to a particular range. The intensity modulation at a horizontal line corresponding to the range of a target will have a cyclic variation depending upon the target velocity. A filter bank selects the signal and applies it to a  B-display cathode-ray tube. In a second embodiment the echo signals are digitized and applied to a storage matrix which replaces the storage tube. The digital signals in each matrix horizontal line represent echoes from a corresponding range and cyclic variations in the digital signals indicating the presence of a moving target are extracted by a Fourier analysis type of frequency selector. In a further modification the storage matrix is replaced by an array of delay lines which may be either magneto-strictive or quartz. The antenna scans horizontally in azimuth and has a beam width of 1 degree. Doppler cancelling is provided to neutralize the effect of any craft movement.

Abstract: 1,157,024. Winding or unwinding strip. LOEWY ROBERTSON ENG. CO. Ltd. 4 Jan., 1968 [19 Jan., 1967], No. 2973/67. Heading B3E. [Also in Division B8] A coiler or uncoiler for strip material comprises a mandrel mounted on a motor-driven shaft and having a retractable outboard bearing supported by two segment shaped jaws which when in an inner position, clamp the outboard bearing between them so as to embrace the bearing from opposite sides and when in an outer position are detached from the bearing and located at a distance from the mandrel to clear a path for movement of coils on to and away from the mandrel. The mandrel M has a rolling bearing R at its outboard end which is clamped during operation of the apparatus by a pair of jaws 2 and 4. The jaw 2 is integral with an arm 6 which is pivotally mounted at 8 on the base 10 of the coiler. The jaw 4 is pivotally mounted at 12 on the arm 6. The arm is moved from the solid line position (its inner position) through the broken line position to the chain dotted position (its outer position) by an hydraulically operated toggle mechanism. A first toggle link 22 is pivotally connected at 24 to an upright part 15 of the base and is also pivoted to a second toggle link 16, which is pivotally attached at 14 to the arm 6. An extension of the link 14 is coupled by a connecting link 30 to the jaw 4. The toggle is operated by an hydraulic piston and cylinder assembly 40, pivotally attached to the base at 41 and to the link 22 at 44. As the piston-rod 42 is retracted into the cylinder, the link 16 rotates clockwise, and through the link 30 causes the jaw 4 to rotate anticlockwise. Further movement of the piston causes the arm 6 to rotate clockwise and swing the jaws to their final position.
