Title: Method of sealing tubes and charging and sealing thermal responsive elements
IPC: B21D39/04
Filed: 1951-07-27
Abstract: 702,005. Making thermal responsive elements. RANCO, Inc. July 27, 1951 [Feb. 15, 1951], No. 17836/51. Classes 83 (2) and 83 (4) A method of sealing a copper or copper alloy tube by cold welding comprises confining diametrically opposite sides of the tube, collapsing the tube by said confining means and then crushing the collapsed portion by crushing tools operating in a direction normal to the confined diameter of the tube thereby causing longitudinal flow of metal from the confined area until the tube is severed. The invention is applicable to charging and sealing a thermal responsive element of the type including a chamber 10 comprising two dish-shaped flexible walls of beryllium copper and a copper capillary tube 11 hermetically sealed to the chamber 10. For exhausting and filling the element with a thermal responsive fluid the open end of the tube 11 is connected to a manifold M which may have a plurality of tube connecting means. The interior of the manifold is connected to an exhaust pump P through a pipe line 14 and a cut-off valve 15 and also to a cylinder C containing the thermal responsive fluid, e.g. sulphur dioxide, methylchloride, butane or propane through a pipe line 16 and a cut-off valve 17. After the element is charged with fluid and while the tube 11 is still connected to the manifold, the tube 11 is sealed by cold welding and severed by a device S comprising an annular body 20 having a central opening 21 through which the tube extends. The body 20 has four rectangular radial openings 22 in which bar-shaped jaw members 24, 25, 26, 27 of hardened steel and having arcuate-shaped inner ends may be reciprocated to depress the sides of the tube inwardly. The jaw members are spring-loaded outwardly and forced inwardly by hydraulic pistons operating in cylinders 37, 38, 39, 40. Pipe lines 42, 44 are connected to a control valve 48 and pipe lines 41, 43 to a valve 49 so that opposing pistons are operated simultaneously. The jaw members 24, 26 have limited inward movement so that after collapsing the tube they are sufficiently spaced to permit the members 25, 27 to move between them to cold weld and sever the tube. The sharp edge of the severed end may be enclosed by a cap consisting, of a sheet metal sleeve 47 frictionally telescoped over the end of the tube the tube end then being dipped into a low temperature molten solder which forms a coating 48 over the sleeve and closes the outer end thereof. The thermal responsive element may be used to operate electric switches, valves, gauges, &c.

Title: Hierarchical data storage systems
IPC: G06F12/08
Filed: 1976-05-06
Abstract: 1531926 Multi-level storage systems INTERNATIONAL BUSINESS MACHINES CORP 6 May 1976 [23 June 1975] 18559/76 Heading G4A Each basic storage module BSM 20 includes sections of an upper, slower access, larger level L3 and a lower, faster access, smaller level L2, paging occurring within each module, and a common control system is arranged to control the interconnection of a plurality of users (processors 12) to the modules 20 so that it is possible to concurrently access all the modules 20 and, when conflict between modules for the same user port arises from concurrent outputs of the upper and lower levels of different modules, priority is granted to the module whose upper level has been accessed. In the system described the fastest access level is formed by the dedicated cache memory L1 of each processor. When data requested by a processor is not in its cache memory L1, the request is extended over the respective bus 33 to a request queue control 15. Each request includes the L3 address, processor identifier and an instruction identifier. Control 15 assigns an available queue slot to each request and identifies the slot by an index 0-7. The high order bits of the L3 address identify one of the BSM's 20 and control 15 passes the address and the assigned slot index to the identified BSM over a bus 26, the address being stored in a register 22 and the slot index in a register 24. Each register 22 is part of a level determining arrangement which includes a L2 directory and which provides a signal LVL on a line 25 indicating whether the requested data is in level L2 (0) or in level L3 (1) of the associated BSM. When a selected BSM is ready to perform the requested data access, it sends the queue index in register 24 over a bus 27 as a response to the priority network 11, all simultaneous responses being ORed together at 28. Priority network 11 comprises a set of gates for each level L2 and L3, each gate in a set corresponding to one of the index responses QIRB0-QIRB7. The gates for level L3 are enabled by the combination of the appropriate QIRB and the corresponding LVL signal on bus 25 provided a higher order (lower index) gate in the same set has not been enabled. The L2 set of gates are only enabled if no L3 gate is enabled whereby in the event of coinciding L2 and L3 responses, L3 is given priority. Network 11 provides the selected index value as output to read the corresponding queue slot, the processor identifier being used to control a cross-bar switching network 17 to complete a connection between the requesting processor and the responding BSM over buses 31, 32, and the instruction identifier and address are passed to the requesting processor so that it is able to associate the data transferred with the instruction which initiated the transfer. Storage level L3 may be monolithic, transistor or core storage. A similar response handling system may be provided for each of a number of subsystems comprising processors and BSM's sharing a data transfer path.
