Title: Sheet metal joint and method of fabrication
IPC: B21D39/03
Filed: 1962-07-30
Abstract: 938,253. Attaching handles; riveting. E. C. FRAZE. July 30, 1962 [Aug. 11,1961; May 2, 1962], No. 29214/62. Classes 83 (2) and 83 (4). In a method of attaching an apertured sheet-like member to a sheet of deformable material without destroying the continuity of the sheet, a hollow boss is formed in the sheet, passed through the aperture in the member and compressed to form a bead which spreads over the periphery of the aperture. A tab 28 is attached to the end of a tear-strip 25 formed in the end 22 of a can 20 by forming a dimple 40 in the end 22 (Fig. 4), reforming the dimple to a straightsided boss 36 between dies 48 and 50 (Fig. 6), passing the boss 36 through an aperture 32 in the tab and then impacting the top surface of the boss (Fig. 14) to cause the metal to flow radially outwards and form a bead 36a engaging the periphery of the aperture. During the impacting operation the boss is supported on an anvil 65. The tab is formed with a second aperture 30 (Fig. 10) which creates a line of weakness at which the tab bends upwards to serve as a handle, the aperture 32 is chamfered at 35 (Fig. 11), and there may be a rib 34 formed around the aperture 32. Where the rib is omitted there is no confinement of the metal and the resulting joint is as shown in Fig. 26 where the metal flowing radially outward overlies the upper surface of the tab 126. In a modification (Fig. 23) the impacting punch has a pair of opposed downwardly projecting abutments 170, 172 which partly confine the metal and result in the formation of thickened bars 176 and 178.

Title: Improvements in handling and conveying hot metal stock
IPC: B21B43/00
Filed: 1925-11-19
Abstract: 257,789. White, A. E., (Morgan Construction Co.). Nov. 19, 1925. Roller-way conveyers.-In a conveyer having skew rolls for side-stepping and reducing the velocity of hot bars delivered endwise in close succession from a rolling-mill, each bar is maintained in its line of delivery until its entire length is supported on the skew rolls, thus avoiding bending of the bars. The bars 1, travelling on conveyer rolls 2 of ordinary construction, pass between pinch rolls 8 to the receiving portions 14 of skew rolls 10 which are shaped as shown in Fig. 2 and which, for the purpose of spacing the successive bars, are rotated at a higher peripheral speed than the conveyer rolls. All the rolls are driven from a motor 7 by gearing as shown in Fig. 1. A modified form of skew roll is also described. In operation, as soon as the bar is released by the pinch rolls, it is accelerated until it reaches the surface speed of the roll portion 14. Thereupon the friction becomes sufficient to cause lateral movement of the bar along the portions 17 of the rolls., this movement being-accompanied by a reduction of speed of the bars and causing the overlapping of the bars as shown in Fig. 1. In a modification, the end clearance between successive bars is effected by a series of high speed cylindrical conveyer rolls, and the skew rolls are driven at a lower speed so that, in operation, the bars skid over the portions 14 until their speed has decreased to the surface speed of the rolls whereupon the side stepping of the bars takes place as before. In this modification, the conical rolls may be replaced by cylindrical skew rolls.

Filed: 1971-06-22
Abstract: 1327856 Data storage INTERNATIONAL BUSINESS MACHINES CORP 22 June 1971 [29 June 1970] 29321/71 Heading G4C A two level data storage system comprises a main or backing store 9 and a high speed or buffer store 1, addressed by virtual addresses, there being an addressable directory store 11 which contains entries relating virtual addresses to main store addresses and a directory store addressing means which generates a sequence of pseudo random directory store addresses from a virtual address whereby a search of the directory store is effected to find the main store address corresponding to the virtual address. A CPU 3 sends a virtual address to store 1 and, if the addressed data is there, it is returned to the CPU. If it is not there the virtual address goes to the directory store 11 where it is searched for as described. Data is stored in store 9 in variable sized pages (e.g. 64, 256, 1024, or 4096 words) and a particular virtual address may be included in any of the 4 page sizes. The size is unknown at the start of the search and the sequence of directory addresses must locate it regardless of size. The directory has a set of entry locations or directory addresses and each virtual address has a subset of this set within which the address may lie. The subset of addresses is generated by randomizing the virtual addresses and using the result to address the directory i.e. the directory location is computed as a pseudo random function of the virtual address and a count H (va, cnt). The first directory entry fetched is at directory address H (va, o) and comprises an I.D. (which can be copy of the virtual address) and the physical address or store 9 at which the page begins. If the I.D. does not identify a page containing the virtual address, the entry of H (va, I) is tested and this continues for incremental counts until the data is found or until the count exceeds a predetermined number when the data is deemed to be missing. Magnetic discs and tapes are mentioned.
