Abstract: 875,918. Radar. PLESSEY CO. Ltd. Jan. 14, 1958 [Jan. 14, 1957], No. 1325/57. Class 40(7) [Also in Group XXX] In apparatus for the transmission of information from a vehicle moving along a predetermined path past a fixed point by reflection of microwaves from a coded linear longitudinal array of alternate reflecting and non-reflecting surfaces on the vehicle the transmitter beam width at the array and in the direction of vehicle movement is not greater than the length of the shortest of the surfaces. As applied to railway wagons arrays 2, 3 are so inclined that reflections are directed only to their respective receivers 5, 6. Transmitting aerial reflector is ellipsoidal to afford a beam wide enough vertically to cover both arrays. The code is afforded by the pattern of array 3, array 2 being provided to effect decimal numbering and to render the system independent of wagon speed. The identity displayed is rendered independent of wagon travel direction by arranging differing combinations of array patterns at their ends. To reduce the effect of spurious pulses received when no wagon is present, there is provided a gate 16 actuated by pulses received when the leading parts of the array patterns pass through the beam. The transmitter. may be amplitude-modulated. Specification 757,300 is referred to.

Abstract: 890,322. Endless conveyers for bottles and like articles. MEYER MANUFACTURING CO., GEO. J. Jan. 14, 1960 [May 26, 1959], No. 1398/60. Class 78 (1). [Also in Groups XVII and XXXII] Articles such as bottles being discharged from a conveyer into collecting pockets in which rows are received, are decelerated in their travel towards the closed pocket ends by means offering increasing resistance to their movement. The invention is described as applied to bottle cartoning apparatus in which bottles 8 advanced by a conveyer 10 and separated into rows by guides 16 enter pockets P, the walls 22 of which are movable transversely so that the bottles, initially supported on fixed members 20, drop between these members into the carton beneath. Protruding from the fixed plate 66 forming the pocket ends is a series of pneumatic buffers 64 which are pushed rearwardly by the bottles against resistance due to discharge of air from their cylinders. Towards the end of their stroke the air escape is progressively restricted, to give a shock-free stoppage of the bottles, by a spigot on the piston restricting air exit from the cylinder (see Group XXXII).

IPC: G01N23/222
Filed: 1957-01-15
Abstract: 824,789. Radioactive analysis. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Jan. 15,1958 [Jan. 15, 1957], No. 1458/57. Class 40 (3). The concentration of a trace element in a base material is determined by subtracting the electrical outputs corresponding to the gammaray spectrum produced by two irradiated samples of the material, one of which contains the trace element. In the Figure the two matched thallium activated sodium iodide crystals 3 and 4 are exposed to the samples 5 and 6 respectively which have been previously irradiated by a neutron source, associated similar photo-multiplier tubes 1 and 2 detect the scintillations produced. By means of switch 8, operated at ¢-second intervals in conjunction with switch 11 the output of each photomultiplier is passed in turn through an amplifier 9 to the kicksorter 13 the bias of which is controlled by the recorder 10. The kicksorter output is applied via switch 11 to the ratemeter 12 in which the outputs corresponding to the pulse rate of each source at the energy level corresponding to the kicksorter bias setting are subtracted, the resulting signal being recorded at 10. The kicksorter bias is varied over a range corresponding to the energy range required, hence the recorder indicates the difference in the two gamma-ray spectra and isolates the spectrum of the trace element. The concentration is measured by comparison with the spectrum of a known amount of irradiated trace element.
