Abstract: 1,231,498. Radiation monitoring arrangement. NATIONAL RESEARCH DEVELOPMENT CORP. July 31, 1969, [Aug.5, 1968], No.37346/68. Heading G1A, [Also in Divisions C4, H4, H5] In a gamma camera which includes a collimator 1 for collimating the rays parallel to a given axis, a scintillation screen 3 for the receipt of the collimated radiation, and a vacuum tube image intensifier 5, the collimator has a plurality of apertures arranged in a two-dimensional array in a plane at right angles to the axis, and is mounted with freedom for movement along the two dimensions in the plane, whereby, by maintaining substantially random movement of the collimator during use of the camera, the limitation upon the resolution imposed by the collimator aperture size is reduced. The lead collimator 1, Figs. 1 and 2, is mounted in a plate 24 which is displaceable in mutually perpendicular directions by double-acting pneumatic or hydraulic cylinders 26a and 28 supplied by a distributor system, not described, which ensures substantially random motion of about 10 to 20 oscillations per exposure. The light is focused on the photo-cathode of image intensifier 5 by a polymethylmethacrylate lens 4, the final image being received by a camera or closed-circuit television system 7. Preferably, to reduce background illumination of the intensifier 5, the screen 3 is mounted in the smaller end of a frusto-conical light pipe the smaller end of which faces the collimator, and around the periphery of the larger end of which a plurality of photo-multipliers is arranged, whereby the sum of the output signals of the photo-multipliers is dependent upon the energy of the photon-generating event which causes a scintillation, but is independent of the position of the scintillation on the screen. The sum signal from the photo-multipliers is sampled by a pulseheight analyser which selects only those pulses of a height-corresponding to a desired photongenerating event, which pulses are employed to energize the image intensifier.

Abstract: 1,265,585. Automatic exchange systems. SIEMENS A.G. 20 March, 1970 [21 March, 1969], No. 13453/70. Heading H4K. A programme controlled data processing system for a telephone exchange has a programme store instructions in which when read out to a decoder control a processing unit, the processing unit having an operand store and a selection circuit which determines which out of a number of bits of data present in the operand store is to be dealt with next. As shown in Fig. 2, the processing unit has operand stores OR1, OR2, and a set of processing units including the selector unit W, a NOT-gate I, a shift element S, a comparator C, AND-gate U, OR-gate O, adder 1A and a test element mvn. Operations are controlled by instructions y delivered from the programme control and guided by address data x. Data buses B1, B2 route the data. Conditional shift commands on lead l can be originated in the comparator or be obtained by way of a switching network SN. The select circuit W can determine which of a group of concurrently active substations, is ringing and can indicate which one of those is nominated for processing. Such one-at-a-time selection may be made according,to a principle dictated by data stored in an operand register. The starting point from which a sequential testing is employed to select a first qualified candidate may be altered by shift element; command. Such selection can also be applied to route selection, section by section, across a switching network: and can be applied to selection in matters of internal processor functions. The form of the selector circuit can comprise a chain of elements such as shown in Fig. 4, an element being associated with, a corresponding unit of the group in respect of which, a selection is made. An element is a candidate for selection if it is marked by a potential on terminal p and this: will result in a select'output on terminal z only if the left-hand element of the chain provides a positive input on terminal k1, such input being present if the terminal is the marked starting point of the selection chain or if no other candidates for selection intervene between the starting point and the element.
