Patent GB-686787-A (GB)
Abstract: 686,787. X-ray and like apparatus. SIEMENS - REINIGER - WERKE AKT. - GES. April 13, 1950 [April 25, 1949], No. 9173/50. Class 98 (i). [Also in Group VI] In apparatus comprising a unit rotatable about an horizontal axis and containing a source of radiationsuitable for medical purposes and a patient's bed, the guides for the rotatable system are provided on an arc disposed in a single plane lying perpendicular to the axis of rotation, the diameter of the arc being at least equal to the length of the patient's bed. It may consist of an X-ray examination apparatus, in which the X-ray tube, the fluorescent screen or photographic plate, and the patient's bed are so mounted as to form the rotatable unit. As shown in Fig. 1, a tubular ring 5 is mounted on rails 6, in turn mounted by spacing members on rails 1 fixed to a wall and to the floor. A rectangular frame 8 carries rollers 7 which ride on ring 5 and is rotatable about its centre A by means of an electric motor 9, mounted on the frame and driving a gear-wheel engaging a toothed arc 11 on the ring 5. Frame 8 supports a cross-member 12 on which a second electric motor 13 and a carriage 16 (not shown) may slide. The motor 13 has a gear engaging a rack 15 on member 12 and is supplied through contacts sliding on current-supplying rails parallel to the rack. The motor 13 and carriage 16 are equal in mass and are connected to an endless belt 20 passing over rollers on member 12. An X-ray tube 17 and beam-limiting tube 18 are pivotally mounted on the carriage 16, and have attached thereto a slotted link 19 engaging a pin 21 fixed to frame 8. A fluorescent screen or cassette for photographic material 24, together with a Bucky or like grid 25, is mounted to slide by engagement with link 19 beneath a bed 22 for the patient mounted on frame 8. The distance of bed 22 from the centre A is variable, and the bed has an adjustable foot-rest 26. The apparatus is adjusted with the bed in its lower, horizontal position, and motor 9 is energized to turn the frame 8 to the required position. The weight of motor 9 substantially balances the weight of the patient. Motor 13 is then energized and moves along rack 15, moving tube 17 and the screen or cassette 24, the tube 17 being meanwhile energized. Frame 8 may be fixed to ring 5, which may be rotatable on fixed rollers. In a modification, Fig. 5, a frame 37 is rotatable on a fixed ring 35 and carries diametrically opposite brackets 39. Circular plates 41, joined by rails 42, are mounted in circular bearings in brackets 39, forming an assembly rotatable about an axis B-B. A carriage 44 is slidable on rails 42, and carries further slidable carriages supporting an X-ray tube 48 and a fluorescent screen or photographic cassette 51 with Bucky or like grid. A trough-like support 53 into which a patient may be strapped is supported between the plates 41 to rotate about an axis C-C. Reference has been directed by the Comptroller to Specification 681,602.

Title: Method and Installation for Producing Cast-in-situ Piles
IPC: E02D5/38
Filed: 1979-02-07
Abstract: The invention relates to civil engineering and is concerned with a method and installation for producing cast-in-situ piles, which provide for a speedy driving of a casing pipe into the ground and a high degree of compaction of concrete mix. According to the invention, a casing pipe (1) is set on the ground. A fluid is fed into the casing pipe (1), and electric pulses are passed through the fluid to produce electric discharges resulting in electrohydraulic effect whereby the casing pipe (1) is driven into the ground. While the casing pipe 1 is being pulled from the ground, concrete mix is fed thereinto and compacted by similar electric discharges. The installation for carrying out this method comprises a pile puller (2), a pile driver (3) and a concrete feeder (4) which are all coupled to the casing pipe (1). The pile driver (3) incorporates a fluid feed system (6) communicating with the casing pipe (1), and a pulse device (8) including electrodes (11 and 12) installed at the lower portion of the casing pipe (1) and intended to produce electric discharges in the fluid fed into the casing pipe (1) by the fluid feed system (6). The invention is useful in laying of foundations of concrete and reinforced concrete piles for apartment and industrial buildings, hydraulic structures and other facilities. <IMAGE>

Abstract: The invention relates to a focal plane camera shutter which enables special effects to be obtained. The shutter has a slit 25 which traverses the picture frame 12 over a period of several seconds, the slit width remaining constant during the traverse. Because of the length of time it takes the slit to traverse the picture frame, it is possible to alter the contents of the picture frame during exposure. This can be done by movement in the picture, or by changes in the camera settings during the exposure for example, the aperture or the effective focal length of the lens. <IMAGE>
