Abstract: 1319179 Image converter tubes; semiconductor targets SIEMENS AG 15 Nov 1971 [13 Nov 1970] 52991/71 Headings HID and H1K [Also in Division H4]  The location of gamma rays 15, Fig. 1, incident on a scintillator 14 is determined by means of a converter tube wherein electrons from a photo-cathode 3 form an image on a semiconductor plate 8 provided with orthogonal conducting output strips 16 and 17 on opposite faces. The plate 8 may be of N-type silicon 300 microns thick with gold strips 16 on one side and aluminium strips 17 on the other, there being 10 to 140 strips on each side. The scintillator may be coupled to the photo-cathode through a light guide 12 formed by glass rods 7 mm. in diameter, with intervening coupling layers 11 and 13 of silicone oil, and may be preceded by a collimator 14<SP>1</SP>. The device may be used medically to determine the distribution of radio-active material in an organ. Location circuit. Fig. 3.-Electrons corresponding to a single gamma ray are arranged to impinge on a target area such as 45 covering at least nine crossing points of the electrodes. The X-co-ordinate electrodes 18-22 are connected directly to a summing amplifier 30 and to weighting resistances 35-44 which weight the output of each electrode in accordance with its co-ordinate position. The weighted outputs are summed in amplifier 29 and the quotient of the outputs of amplifiers 29 and 30 is developed in unit 31 and corresponds to the X co-ordinate of the centroid of area 45. The Y co-ordinate is derived similarly and the two co-ordinates may be fed to an oscilloscope 32 or other output device. The output of amplifier 30 may also be fed to a pulse height discriminator 46 which reduces interference by blanking the display 32 if the input corresponds to an unwanted low energy gamma ray.

Title: Terminating coaxial cable
IPC: H01R9/05
Filed: 1968-11-13
Abstract: 1,204,450. Making coaxial connectors, jointing by forging. AMP Inc. 13 Nov., 1968 [11 Dec., 1967], No. 53832/68. Headings B3A and B3H. [Also in Division H2] A method of terminating a coaxial cable 10, having a metallic tubular outer conductor 12 separated from an inner conductor 16 by dielectric material to a connector half including a tubular body 24 or 52 having a bore through which the cable can pass, and which has an enlarged portion at the rear end of the body, comprises the steps of positioning the tubular body over the cable end, placing a ferrule 36 or 68 of ductile material in the enlarged portion of the bore, holding the tubular body fixed relative to the cable end and applying an axial force to the ferrule to deform it by a predetermined amount to secure the tubular body to the cable. The ferrule 36 is first positioned on the cable and then the body 24 is moved into place. A clamping sleeve 102 is threaded into a nut 44 of the connector half 20 to align the end 26 of the body with the cable end and to cause an element 120 to grip the inner conductor 16 by means of a taper 122 mating with a corresponding tapered bore 116 in the sleeve 102. A sleeve 82 is then positioned over the cable, die elements 70, 72 placed as shown in Fig. 5 and the sleeve 82 moved over them. A sleeve 92 is next screwed to the sleeve 82 thereby moving the elements 70, 72 so that projections 76 thereon deform the ferrule 36 against the end surface of the enlarged portion of the bore of the body 24. Movement of the dies stops when surfaces 78 thereon engage the end surface of the body 24. With reference to the mating connector half 22, the ferrule 68 is first placed on the cable with a body 52 positioned thereon. A holder 134 fitted within a further sleeve 92 is threaded on to the half 22 until the forward portion thereof bottoms against the cable end and ferrule thereby properly positioning them and the cable elements. The conductor 16 lies within a bore 142 of a tubular portion 140 of a nut 138, which limits the axial position of the holder 134 in the member 92. Die elements 70, 72 are fitted to the cable and a further sleeve 82 slid thereover and threaded into the sleeve 92. Thereafter the sleeves are relatively rotated to deform the ferrule 68 as with the ferrule 36. Inspection ports (154) may be provided to ascertain that the ferrules are properly deformed, Figs. 1, 7 (not shown), and two or more ferrules may be used on each cable instead of a single ferrule.
