Title: Apparatus for measuring x-ray absorption
IPC: G01N23/06
Filed: 1974-01-09
Abstract: 1407931 Measuring x-ray absorption SIEMENS AG 9 Jan 1974 [7 Feb 1973] 01123/74 Heading G1A X-ray absorption measuring apparatus comprises a beam source with two detectors in fixed relationship therewith and aligned with the beam, all forming a unit movable relatively to an object placed between the detectors, the ratio of the detector outputs representing the degree of x-ray absorption by the object. An x-ray tube 1 powered by a substantially stable supply 10 directs a narrow beam 5 through a first detector 2 to a second detector 3, the beam 5 passing through a point 6 of an object 4 (e.g. a patient's head). By translation in the direction 8 the unit scans a plane in the object 4, the successive degrees of absorption by the object being calculated by the computer 9 from the ratios of the detector outputs, whereby any errors due to fluctuations in the intensity of the source 1 are substantially eliminated. At the end of a scan the unit returns to the position shown in solid lines, then rotates a small amount about the axis 6 and scans again in the direction of the dotted arrow, progressively repeating the process until it comes full circle. Thus a tomographic matrix of information is built up, enabling the boundaries of normal tissues and abnormal conditions to be identified.

Title: Furnace Structure
IPC: C21B7/00
Filed: 1967-01-09
Abstract: 1,172,122. Blast furnace supports; platforms. HEAD WRIGHTSON & CO. Ltd. 9 Jan., 1967 [17 Jan., 1966], No. 1151/67. Heading F4B. All or a considerable fraction of the weight of a blast furnace is taken by a generally rectangular frame 12, surrounding and spaced from the furnace above a bush ring 13, said frame being supported by a leg 14 at each corner engaging foundation members 15 set in the earth. The frame 12 comprises deep I-section girders 38, eight connector members 43 disposed equiangularly about a vertical axis A and connected as by welding or bolting to the web of each associate I-beam and the furnace shell 6. Associated with the top and bottom of each of the members 43 are structural rings 45 and 13 fixed to the furnace shell. A compression ring member 51 in the form of a regular octagon welded to the top flanges 40 of the girders 38 has internally-extending projections welded to members 43. An auxiliary frame member 23 has legs 24 connected to the frame 12, said legs carrying working platforms 25 and 26. Pairs of divergent turn-buckles 56 extend between the furnace shell 6 and girders 59 forming the top of auxiliary frame 23. Similar turn-buckles extend between the furnace shell and the frame 12. The bottom portion 62 of the hearth 9 is semi-ellipsoidal in shape and of circular cross-section. It is lined with carbon bricks 64 which extend upwardly to meet the shaft lining 61 which incorporates conventional cooling plates. The legs 14 and girders 38 are prestressed so that when subject to their full load they will be straight. This is achieved by bowing girders 38 upwardly and drawing the lower ends of legs 14 radially outwardly and holding them in such a position as to allow said lower ends to rotate freely without subjecting them to bending moments. To this end a metal base 66, Fig. 7, is bolted to each foundation member 15 and is normal to the leg axis B when the leg is straight. An adjustable member 67 rests on member 66 and is formed with an annular groove 68 engaged by a flange 77 on a casting 75 forming the bottom of the leg. Groove 68 and flange 77 have mating part spherical seatings 71 and 76 of hardened metal. Each member 67 has lugs 78 connected by a draw bolt 79 to a lug 81 fixed to the base, so that by tightening nuts 82 on the bolts 79 each leg can be moved to its prestressed position. Each leg is filled with concrete 121 which may incorporate steel reinforcements 122. In a modification, Fig. 9 (not shown), the hearth is supported by a foundation set in the ground. The connector members from the girders 38 may be attached to flanges on the furnace shell which is cooled by vertical elongated cooling plates (102, 103) and by conventional cooling plates in the bush area, Fig. 10 (not shown). In a similar construction, Fig. 11 (not shown), the whole wall is cooled by conventional cooling plates.

Filed: 1943-01-25
Abstract: 561,637. Artificial hands. HOARE, C. G. Jan. 25, 1943, No. 1227. [Class 81 (ii)] Operating mechanism for pivoted thumb and/or finger joints of artificial hands comprises a base block 11, fixed to the body of the hand, a jointmovement operating piece 12 slidable thereon and adapted to be clutched thereto by a oneway friction clutch 19, 21 and an actuating member 13 movable by a flexion cord 25, against a spring 24, for moving the piece 12 in one direction and for releasing the clutch. A pivot plate 9, fixed to the block 11 on the inner surface of the palm of the hand, has rotatably mounted thereon the ring 12 furnished with an arm 15 which, through a link system 14, moves a pin 8 projecting from the thumb-actuating lever 7. The pin 8 also engages a slot in the finger-actuating lever 4. The thumb and fingers, which may be rubber-padded, are respectively pivoted at 6, 3 so that movement of the pin 8 actuates the thumb and fingers to open together or to close together. Upon the ring 12 is rotatably mounted the further ring 13, spring-urged at 24 and carrying an arm 32 to which the flexion element 25 is attached. The plate 9 is formed with a wedge-shaped aperture 19 in which is situated a roller 21 carried by a pivoted arm 22, spring-urged at 23, the aperture 19 and roller 22 forming the friction clutch. Pivotally carried on the arm 32 is a detent 26 and a spring-urged pawl 29. Springs' 20 operate to bias the fingers and thumb to the fully-opened position. When it is desired to re-grip an article, the flexion element is pulled which moves the pawl 29 to trip the clutch thus allowing the fingers and thumb to open under the pull of the springs 20. Further movement of the member 25 causes the detent 26 to fall into the niche 27, thus moving the ring 12 to effect re-grip and also clearing the pawl 29 from the nose 30 of the arm 22. Release of pull in the member 25 will allow the ring 13 to move back to the Fig. 4 position under the pull of the spring 24.
