Title: Circuit arrangement for flattening an energy response of a scintillation counter in bias modulation of a threshold discriminator
IPC: G01T1/20
Filed: 1964-10-30
Abstract: 1,082,957. Radiation dosimeters. JAPAN ATOMIC ENERGY RESEARCH INSTITUTE. Oct. 30, 1964 [Nov. 1, 1963], No.44449/64. Heading G1A. The number of pulses produced by a scintillation counter is made proportional to the dose or dose rate received by connecting the scintillation photo-multiplier to a counter through a threshold discriminator to which is applied a cyclicly varying bias. The waveform of the bias is so chosen that the proportion of the cycle in which pulses can pass to the counter is proportional to the energy of the corresponding incident y or particle quantum. Thus for a plastic scintillator, in which pulse height is proportional to the incident energy, a sawtooth waveform is used. For a NaI scintillator, a more complicated waveform is used, Fig. 5 (not shown)

Filed: 1962-11-27
Abstract: 1,016,451. Machinery guards. HENRY ALLDAY & SON (1922) Ltd. Oct. 29, 1963 [Nov. 27, 1962; May 13, 1963], Nos. 44769/62 and 18803/63. Heading F2J. If, during the working stroke of a toolcarrying slide 2 of a press, a guard 33 connected to the slide for limited movement relative thereto in the direction of slide movement is obstructed, a roller 8 in a tapering cavity between a side of the slide and an adjacent part of the press body 1 is caused to wedge therebetween to stop further slide movement. A support plate 11 fixed by screws 10 to the slide 2 is connected by two pairs 14a, 14b of parallel arms, to a carrier plate 16, pivot-pins 15 connecting the arms to the plate 16 passing through slots 15a in the plate 11 to limit the relative movement between the two plates. Parallel arms 24 pivoted at 25 to the carrier plate 16 support a plate 26 carrying the guard 33, a bias spring 30, anchored to a lug 28 on the plate 26, urging the guard downwards. A roller 31 on an extension of the upper arm 24 cooperates with a fixed cam 32 to allow the guard to move into the safe position in advance of the slide on the working stroke, while causing the guard to rise clear of the stationary tool portion 5 when the slide 2 is raised. The roller 8 rests on the end 9a of an arm 9 adjustably mounted on the carrier plate 16 and lies in a cavity 6 in the slide 2 between a tapered insert 7 and the body 1. Obstruction of the guard 33 during the working stroke of the slide 2 causes upward movement of the plate 16 relative to the slide, the resultant upward movement of the arm 9 forcing the roller 8 to wedge in the tapered cavity and lock the slide. To release the roller, the slide is raised slightly. A stop 34 prevents upward movement of the plate 16 at the top of the slide stroke.

Title: Improvements relating to the handling of steel slag
Inventor: GRADY JOHN JOSEPH
IPC: F27D3/15
Filed: 1962-11-27
Abstract: <PICT:1029677/C6-C7/1> In a process of granulating and disposing of the slag from an open hearth furnace, the molten front flush steel slag flows via an adjustable shoot into a granulator where it is granulated by a water jet and the granulated slag is continuously removed by, for example, a rake conveyer.  A pair of water jets may be mounted one above the other in the wall of the granulator and the level of the water in the granulator is maintained below the point of intersection of the water jets and the slag stream.  The slag shoot is adjustable so as either to direct the slag into the granulator or on to the pit floor.  The granulated slag is subjected to magnetic separation.  As an optional feature a granulator may also be located on the pit side for granulating the slag from the steel ladle or alternatively this slag may be directed to the granulator used for the front flush slag.  Fig. 5 shows the furnace 20, the front flush slag 64 the shoot 78, granulator 82 (shown in more detail in Figs 6-10, not shown) rake conveyer 132, tapping ladle 50, ladle slag 67, slag shoot 79.
