Title: Apparatus for and a method of determining the spectrum of a source which emits ª radiation
Inventor: ZABOROWSKI HENRYK LUDWICK
IPC: G01T1/202
Filed: 1959-08-05
Abstract: 925,629. Radio-activity measurements. COMMISSARIAT A L'ENERGIE ATOMIQUE Aug. 5, 1959 [Aug. 7, 1958], No. 26716/59. Class 40 (3). The spectrum of an α-emitting radioactive source 24 is determined by a scintillation detector comprising a reflective hemispherical container 2 carrying an interior scintillating surface (silver-activated zinc sulphide) and which is adapted for fluid-tight mounting on a photo-multiplier 10, a duct 5 being provided to permit the pressure of gas within the detector to be controlled. The photo-multiplier supplies its signals to a counter through an amplitude discriminating circuit adjusted so that the counter responds only to low amplitude impulses corresponding to α particles reaching the ends of their effective paths at the scintillating surface. Accordingly, as the gas pressure is varied, particles of different energy levels reach the end-of-path condition at the scintillating surface and the spectrum may be determined. The pressure may be varied in discrete steps and a count made at each step, or the pressure may be varied continuously, e.g. with the aid of a small leak, and the count effected as a function of time. The radio-active source is located in the region of the centre of the sphere of which the hemisphere is a part. Where the radioactive source is of appreciable size, i.e. functions as other than a point source, it is preferably covered by an apertured mask which functions to reduce the solid angle over which its radiations are effective. Reference is also made to placing the source off-centre. Hemisphere 2 which is polished internally is welded to a stainless steel ring 4 and is secured to a easing 12 for the photomultiplier 10 by means of clamps 15, 16 with the interposition of a flexible seal 14. The photomultiplier is introduced into casing 12 between the lips of a seal 9 and bears lightly against a neoprene packing 11.

Title: Improvements in the manufacture of reinforced lead sheet
Inventor: CRAIG ROBERT
IPC: B23K1/00
Filed: 1950-11-09
Abstract: 698,265. Making composite sheets; rolling; soldering. LEVER BROS. & UNILEVER, Ltd. Oct. 15, 1951 [Nov. 9, 1950], No. 27418/50. Classes 83 (ii) and 83 (iv). [Also in Group X] A process of making reinforced lead sheet comprises heating a tinned surface of a lead sheet to liquefaction, contacting the liquefied tinned surface face-to-face with a tinned surface of a reinforcing mesh structure of a strainresisting metal, pressing the mesh structure into the liquefied surface and solidifying the liquefied surface, the tinned surface of the lead sheet being liquefied to a depth sufficient to ensure that the reinforcement is embedded throughout the whole of its thickness. The reinforcement may comprise a net or fabric woven from wires or a perforated sheet. In a preferred method lead sheets 9, 10 of 8 lb. lead with their upper surfaces cleaned and coated with solder paint containing powdered solder and a liquid flux, and a centrally-disposed sheet 27 of tinned expanding metal, are fed between rolls 1, 2. The tinned surfaces of the lead sheets are heated to liquefaction point by radial, gas-fired heaters 21, 22, to a depth sufficient to receive the thickness of the expanded metal between them, and the rolls are chilled to a temperature of - 3‹ C. by internal circulation of brine fed from a coil immersed in industrial spirit cooled to a temperature of - 10‹ C. by the addition of solid carbon dioxide. The reinforced sheet emerging from the rolls is guided to one side by the guide 3 and allowed to cool at room temperature in a horizontal plane. The position of the heaters may be varied by movement of the counterweights 15, 16 and finely-adjusted by supporting screws 19a, 20a, and the rolls are driven by a variable-speed motor manually controlled so that the time of travel of the lead sheets under the heaters is sufficient to boil off the flux in the solder paint.
