Title: Scintillation device
IPC: G01T1/166
Filed: 1972-03-23
Abstract: 1360707 Scintillation scanner PICKER CORP 23 March 1972 [25 June 1971] 13646/72 Heading H4F A scintillation scanner of the type described in Specification 1,211,122 includes a calibration system for automatically calibrating the value of data signals representative of measured radiation activity in response to the value of a reference signal representative of the level of maximum radiation activity, i.e., a signal representative of radiation activity at a calibration point or a "hot spot". The calibration system utilizes circuitry for counting the number of pulses which occur at the calibration point for a predetermined number of intervals of time, and then dividing the number of counted pulses by the number of intervals of time to develop a calibration signal having a high degree of statistical accuracy. The values of the data signals obtained during the normal operation are then modified by the calibration signal so that the data signals always remain within a preselected range of values regardless of the levels of measured radiation activity. This ensures that when a visual recording of the measured radiation activity is produced using different colours for different activities, i.e. counts per minute, the entire colour spectrum available is utilized. The recording is effected using a pulsed light source in conjunction with a film plate, and in addition to modulating the intensity of the light pulses with the modified data signals, the duration of the light pulses is controlled in response to the output of a pulse height analyser (from which the data signals are derived) and the calibration signal.

Patent GB-567289-A (GB)
Title: Improvements in or relating to the production of trichloracetonitrile
Filed: 1942-10-02
Abstract: A mixture comprising not less than three molecular proportions of chlorine per molecular proportion of acetonitrile is passed over a non-volatile chlorination catalyst at a temperature above the boiling point of the product, viz.: trichloracetonitrile.  The reaction gases are condensed and, on distillation, a residue is obtained which by further fractional distillation under reduced pressure gives a trimer and tetramer or trichloracetonitrile.  In an example, chlorine is passed into a vessel containing acetonitrile maintained at about 38 DEG  C. by thermostatic control, and the resulting gaseous mixture is reacted in a catalyst chamber containing active carbon impregnated with barium chloride.  The products are condensed in two stages, first with water cooling, and then with brine at - 10 DEG  to 20 DEG C.  After washing with water and drying, trichloracetonitrile is obtained by distillation.  A similar crude product is obtained in a second example, but using unimpregnated active carbon, and after recovering the trichloracetonitrile, the trimer and tetramer are obtained by distilling the residue under reduced pressure.  Active carbon impregnated with a halide of zinc, copper or any alkaline earth metal may be used.

Abstract: 160,099. Royston, E. R., (Lee Hardware Co.). May 20, 1920. Drawings to Specification). Sketching and writing pads and blocks; bookbinding.-The edges of a number of sheets or leaves are bound together by an adhesive composition which is flexible when dry and allows the book or writing-pad so formed to be laid open flat at any point, or to be bent or flexed without injury. In applying the binding-composition, some parts of the edges are left free, so that adjacent sheets may be stretched apart slightly to permit the insertion of a loose sheet, such as a piece of carbon paper; or so that one or more of the sheets may be torn out without disturbing the remaining sheets. The adhesive consists of 35 parts smoked plantation or fine Para raw rubber mixed by rolling with the same amount of unsmoked first latex, adding 10 parts silica, magnesium carbonate, or fossil flour, 13 parts calcium chloride, 6 parts calcium hydroxide, and 1 part colouring-matter. This mixture is stirred into a solvent consisting of 70 parts carbon tetrachloride and 30 parts benzol to which a suitable deodorant is added. East India gum may also be added to minimize the tendency of the composition to become doughy and to assist quick drying.

Title: Improvements in or relating to machines for the decortication, polishing or for the cleaning or opening of cereals and other grain-like substances
IPC: B02B7/02
Filed: 1924-06-06
Abstract: 239,293. Pollak, J. E., (Kaspar Getreides chõl Maschine Ges.). June 6, 1924. Decorticating and polishing.-A machine having a series of decorticating, cleaning, or polishing chambers through which grain passes in succession as described in Specification 153,253, has the means for transferring the grain from chamber to chamber operated in rapid succession after suitable working intervals so that all the chambers are normally full. The cams 11, 13, Fig. 3, that control the transition of grain &c. from chamber to chamber are mounted on a shaft 10 carrying a toothed wheel 14 having an eccentric portion 15 engaging with a driving pinion 16 mounted on a spring-controlled rocker 18. When the shaft 10 has made one revolution the eccentric portion 15 depresses the pinion 16 and rocker 18 which is then retained by a catch 24 engaging a screw-threaded spindle 25 so that the camshaft 10 stops. The spindle 25 is rotated by worm gearing 27 from the main shaft 23 of the machine so that after a certain period the catch 24 leaves the end of the screw 25 and allows the pinion 16 to engage once more with the toothed wheel 14 to effect another transition of grain. The period is varied by means of an adjustable collar 31 that determines the position taken up by the catch 24 in engaging the screw 25. The admission of grain to the first chamber from a hopper 47, Fig. 10, is effected by the opening of a valve 49 by means of a cam 57 on the control shaft 56. The valve is opened by a spring 50 when the lever 55 moves into the gap 60 in the cam. The cam is composed of a pair of mutilated discs adjustably clamped together by bolts 61 passing through slots 62 so that the size of the gap 60 can be varied to control the duration of the charging period. Alternatively a cam displaceable on the shaft 56 to bring into action different peripheries of various forms may be employed.
