Title: Radiation imaging devices
IPC: G01N23/04
Filed: 1972-11-08
Abstract: 1370084 Scintillation cameras G D SEABLE & CO 8 Nov 1972 [9 Nov 1971] 51425/72 Heading H4F In an Anger-type scintillation camera, the co-ordinate output signal, e.g. x, does not linearly correctly correspond to the co-ordinate value of the scintillation. An example of actual (solid and dot-dashed lines) as against ideal (dashed line) true co-ordinate/signal co-ordinate relationship is shown at Fig. 8 from which can be deduced that an even distribution of radiation sources will give rise in the television display to a pattern of radiation concentrations, Fig. 9, each corresponding to the position of a photomultiplier. The specification therefore proposes irradiating the scintillation crystal with a regular matrix array of point sources produced by a uniform source and a lead shield 30, Fig. 2, having the matrix of holes 31 therethrough. The detected erroneous co-ordinates of each point source are recorded in the form of errors for each true position, together with interpolated errors for positions in between the matrix positions. The shield can be positioned in four different ways corresponding to holes 32 to give errors for 4096 positions which are stored in a 64 x 64 matrix. Figure 3 indicates on 4 x 4 section of the 4096 position matrix. The camera erroneously indicates that a source of radiation (200 units strong) is located at element (x(n), y(m). The recorded errors for this position are + 1À25 and + 2À50. This places the true source position as indicated by the dotted square. To ensure that the corrected position does not extend over several elements at once (e.g. x(n + 1), y(m + 3); x(n + 1), y(m + 2); x(n + 2), y(m + 2); x(n + 2), y(m + 2) as shown), the detected position co-ordinates are converted to 8 bit binary code forms in a 256 x 256 matrix position array, each new element occupying 1/16 of the previous 64 x 64 matrix array element, are stored in ten bit registers after being shifted up by two bits (multiplied by four) and are corrected by adding to the shifted co-ordinate codes, the recorded errors multiplied by four. A random number from the four:- is added to the corrected code, to ensure that the final codes only occupy the desired elemental positions. The positions errors can be reduced by mounting the photomultipliers directly on the crystal, without any intervening light guides.

Abstract: 541,181. Cash registers. NATIONAL CASH REGISTER CO. May 13, 1940, No. 8583. Convention date, May 20, 1939. [Class 106 (i)] The locks for two clerks keys are mounted on a rockable member and are effective when the member is in normal position and ineffective when the member is rocked from this position. The keys 22, 23 are rockable on the shaft 24 and. are held by the weight of the key-coupler 20 with their rear ends engaging a frame member 25. Studs 26, 27 on the keys are latched by hooks 28, 29 rockable on shaft 30. The lever 29 is fastened by a yoke 31 to a lever 32 a notch 33 in which engages the eccentric rimmed cam 34 on the barrel of the lock 35. This together with lock 50 is carried by a lever 36 pivoted at 37. The lever 28 has a cam slot 38 engaged by a stud 39 on a lever 46 pivoted at 47 and having a notch 48 which engages a cam rim 49 on the lock 50. The rocking of either hook 28, 29 to the extreme position clockwise causes it to engage a stud on the associated key locking the latter. By turning the lock barrel through 180 degrees the lever is moved from " eff ective " to " ineffective " position. If the lever 36 be moved slightly counterclockwise, until its arms 52 rests against the shaft 55, the levers 32, 46 are rocked counterclockwise to the position shown in Fig. 6 and the control by the locks is superseded by the lever 36. The arm 52 can only engage the shaft when the control lever 57 has been moved to reset position and the pinion 56 rotated so that the rim of cam 54 is removed from under the end of arm 52. Pivoted about the shaft 24 is an auxiliary cam plate 58 which is carried up with the key 23 by engagement of a stud 59 on the key on which it rests. Pivoted to the plate 58 by a stud 60 is a lever 61 which when rocked counter-clockwise hooks by notch 62 over the edge of the key-coupler to move therewith and carry the plate 58 upward, an arcuate surface 63 contacting the rear end of the coupler and preventing movement of the key. When the A lock is turned 180 degrees from the position shown in Fig. 1, a lever 46 is rocked clockwise and through stud 64 rocks the lever 61 even though the B key is not depressed. The stud 64 will move in raceway 66 on plate 58 and the lever 61 and plate are oscillated. If the lever 36 is depressed the stud 64 will idle in raceway 65. The movement of lever 46 around the stud 47 causes a stud 68 to move past a high point 69 in cam slot 70 of lever 71 rocking the latter so that a surface 72 engages a surface 73 on a stud extending from a plate attached to the key-coupler so as to lock the coupler while lock 50 is being turned. When the coupler is out of home position, the surface 75 on the stud engages the surface 76 preventing operation of the lock when the machine is being operated. In a modification a lock control for the levers 32, 46 is described which requires a 360 degrees movement of the lock-barrels the turning of which move slotted slides the flanges of which perform the function of the barrel rims in the first construction. Specification 458,087 is referred to.

As described the store 10 comprises bi-stables (50-60, Fig. 2, not shown) connected as a shift register stepped twice in each bit interval, the outputs of the bi-stables being connected to the decoder 18 comprising AND gates (70, 72, Fig. 5, not shown) and a NAND gate (74) which delivers a signal on one of the three leads 20, 22, 24 representing (1) advance, (2) delay and (3) a no shift signal to AND gates (84, 86, 88, Fig. 7, not shown) in circuit 26 when (1) the output code from the last five bi-stables is 00101, (2) the output code from all six bi-stables is 010100 and (3) any other -pattern is received. The AND gates in circuit 26 also receive an advanced, normal and delayed clock signal (from a delay network, Fig. 6, not shown) on leads 32, 34, 36 respectively so that one gate is enabled to pass the signal on line 28 representing the bits stored in the fourth bi-stable (56) to write driver 42.
