Patent GB-732958-A (GB)
Title: Improvements in or relating to the manufacture of hollow steel self-hooped or super-pressurized bodies
IPC: B21D26/02
Filed: 1953-11-27
Abstract: 732,958. Stamping. FERRAND, G. A. Nov. 27, 1953, No. 33060/53. Class 83 (4). A sliding joint for a press for use in manufacturing hollow self-hooped or super-pressurized steel members the walls of which are expanded by internal fluid pressure, said joint compensating for longitudinal shortening of the hollow members and constituting an annular block for the member which slides on a part connected to the pressure plate of the press, is characterized in that the annular block has a surface for the application of end pressure, said surface being at least equal to the internal cross-section of the hollow member after expansion, said block having, on its front surface, an annular abutment limiting the expansion of the hollow member. A hollow member 10 to be expanded is held between the plates 13 of a hydraulic press and the sliding joint is interposed between the plates and the end of the hollow member. The joint comprises a steel ring 16 connected to the plate 13 and surrounded by a sliding ring 18 bolted to a member 20 having a recess 21 with an inclined wall 22 and a groove 23. A rubber sealing ring 24 is seated in the groove and provides a pressure-tight seal.between the body 10 and the member 20. Pressure fluid, e.g. compressed air, enters the groove below the sealing ring from an inlet pipe 25. When the hollow member is expanded the sealing ring follows the wall of the recess and ensures a constant seal. Sealing rings are also provided at 30 and 31. The inside diameter of the ring 18 is greater than the inside diameter'of the hollow member 10 so that the inside face 28 of the member 20 always presents to the action of the internal pressure a greater cross-section than the member 10 and, therefore, as the member 10 expands and shortens in length the assembly 18, 20 follows the displacement and keeps the end 19 of the member 10 in contact with the groove 21 (Fig. 2). In a modification, the ring 16 has a step 33 and the ring 18 a complementary step 34 so forming an annular space 35 sealed by rubber rings 36 and 37. By supplying pressure fluid to the space 35 the shortening of the hollow member may be accentuated to maintain its wall thickness constant. Specifications 292,580, [Class 83 (iv)], 340,148, 671,609, 676,569, and 676,598 are referred to.

A device for effecting a connection between a rigid wall 1 and a removable component comprises two rings 3, 14 slidable one within the other and securable respectively to the removable component and the rigid wall, a groove 23 in the ring 3 for positioning adjacent the other ring in use and rigid fastening components which are connectable to the ring 14 and each movable between a fastening position in which it penetrates into said groove and an unfastening position in which it is disengaged from said groove. The ring 3 has a shoulder 4 and a threaded part 5 and in use is fitted in an aperture 2 of the wall 1, a sealing gasket 6 being positioned between the shoulder 4 and an internal face of the wall 1 and a ring 7 engaging the threaded part 5 on the outside of the wall to compress the gasket. The ring 14 is either integrally connected to the removable component in which case circumferential ridges are provided on the ring 14 for sealing engagement of the ring 14 with the interior surface of the ring 3 or as shown the ring 14 is provided with a groove 20 in which a portion of the removable component engages, the portion having three lips, two of which are positioned in the groove 20 and the third of which engages the interior surface of the ring 3 to provide a seal. The rigid fastening components can take a number of forms; in one form three pins are used and these extend through apertures in the ring 14 and engage the groove; the pins are carried by a flexible strip 7. In another form as shown in Fig. I the fastening components are screws 17 which engage through tapped holes 16 in the ring 14 into the groove. In a third form each fastening component has a head and a shank the shank extending, in use, axially of the rings and the ring 14 has a groove which is disposed in use opposite the groove 23 the two grooves receiving the heads; the fastening components can be made of solid material or of folded sheet metal or each could be in the form of a bolt in which case a nut can be screwed on the shank outside the rings. To enable such fastening components to be engaged with the rings the ring 3 has the outer groove wall provided with gaps so that after the fastening components are engaged with the ring 14 they can be introduced through the gaps to engage in the groove 23. The provision of gaps into the grooves 23 enables a mounting and ejecting apparatus to be engaged with the ring 3 for replacing the removable component; when gaps are not required to enable the fastening component to be engaged with the groove 23 an additional groove provided with gaps for the use of the mounting and ejecting apparatus can be provided.

Abstract: 1,269,995. Photo-copying apparatus. R.C.A. CORPORATION. July 4, 1969 [July 5, 1968], No. 33888/69. Heading G2A. In the imaging of a filled in polygon Fig. 4 (not shown) of a predetermined shape on to a photosensitive sheet 10, the polygon is first notionally divided into a plurality of separate smaller polygons (70-74), a number of which are rectangles, and each of these rectangles is imaged in turn by firstly forming a narrow border image (80), Fig. 5 (not shown) by selecting a circular aperture from a plurality of apertures 41 in a disc 42 and moving a copying head 12 containing the disc 42 round a closed path in accordance with data fed to X and Y stepping motors to expose an outline of the rectangle on the sheet 10 and then successive interior images, each formed as a strip by selecting a slit shaped aperture from the disc 42 and overlapping at least one other formed image, are similarly exposed within the outline image, also in accordance with data fed to the motors, until the whole outline image has been filled in. The head 12 is then moved to expose the sheet 10 corresponding to the next rectangle, until all the rectangles have been imaged on to the sheet 10. The non-rectangular polygons are then imaged. The aperture selected to lie in the exposing light beam is selected to minimize the number of movements of the head 12. An outline image is unnecessary where extreme accuracy is not required. In the event of the predetermined polygon shape including a re-entrant angle, at least one side thereof is internally extended to form one side of a smaller rectangular image. The image producing means could alternatively be an electron beam in a cathode ray tube or a pen.

Convention dates, Nov. 30, 1931, and Oct. 15, 1932. [Class 38 (v).] In a switch, which is automatically operated by a thermostat for regulating the temperature of electrically heated metal-pots for type-barmaking and other machines, the terminals 74, 75 of a circuit pass into a vacuum tube 73, and the terminal 74 carries a spring contact 76, which normally touches the terminal 75. The vacuum tube is carried by an L-shaped member 72, which is supported between two chisel-edges 88, 89 formed on the members 84, 85 respectively of a thermocouple, which is mounted on the metal-pot. The members 84, 85 have different coefficients of expansion, and, as the temperature rises, the distance between the chisel-edges increases and the member 72 tilts downwards. One end of a rod 80, which is mounted in a slightly flexible stem 79 of the vacuum tube, meets, and is arrested by, an adjustable stop 81, so that the other end of the rod moves the spring contact 76 away from the terminal 75 and breaks the circuit. An additional resistance is thereby placed in series with the normal heating-resistances, so that the heating effect is reduced.
