Title: Testing an elongate conductor consisting at least partially of superconductor material
IPC: G01R31/02
Filed: 1975-06-30
Abstract: 1499164 Testing super-conductors SIEMENS AG 30 June 1975 [1 July 1974] 27591/75 Headings G1N and G1U Apparatus for testing an elongate conductor consisting at least partly of super-conductor material, comprises: means for generating an applied magnetic field; means for passing the conductor, while the super-conductor material is in the superconducting state, lengthwise along a path transverse to the applied magnetic field; and means located adjacent the path for monitoring the magnetic field generated by currents induced in the conductor. A tape 12 having a super-conductive core is passed round and under a roller 18 of diameter e.g. 40 mm located in a liquid-helium cryostat, so that at its lowest point it is travelling substantially transversely to the region of maximum flux density of a super-conducting electromagnet 16 also located in the cryostat. Secondary magnetic fields generated by eddy currents induced in the tape 12 are detected by a Hall plate 19, or preferably by two Hall plates on respectively opposite sides of the tape, the Hall e.m.f. due to the primary applied magnetic field being backed off in electronic apparatus (24), Fig.2 (not shown). A curve plotted by a chart printer (25) thus represents the secondary magnetic field due to eddy currents induced in the tape 12. The magnetic flux density is e.g. 2-5 tesla; and the tape speed is so chosen (e.g. 1 metre/min) that the induced current attains the critical value corresponding to the applied flux density everywhere within the super-conducting portion. Thus the recorder graph comprises a steady component due to the  mean critical current, with superimposed noise due to surface irregularities of the tape, any flaws in the super-conductive portion being represented by negative spikes. Further coils 23, 23, may be included to superimpose either monotonic or alternating variations on the applied flux, to investigate variations of critical current with applied flux. If an alternating variation is applied, then phase-sensitive detection may advantageously be used to separate timedependent effects such as those due to ohmic resistance in normally-conductive portions of the tape.

Title: Numeral storer for calculating, book-keeping or the like machines
Inventor: HEBEL MARTIN
Filed: 1954-09-25
Abstract: 785,614. Data-storage apparatus. ELDI-FEINMECHANIK GES. Sept. 25, 1954, No. 27743/54. Class 106 (1). In a number-storage device comprising a group of resilient comb-shaped plates each having one tooth for each denomination and, for each denomation, two members, one normally locking the corresponding teeth and being movable to release them for deflection to registering positions and the other being movable to couple sensing bars with the corresponding teeth for reading out the stored number, the members of the two sets are operated alternately and in sequence by cams on a single shaft. In a decimal arrangement, four plates 19 are selectively pivoted by electromagnets 21-24 to cause a digit to be stored in coded form in a denomination selected by the rocking of the corresponding latching plate 33, which releases any of the associated teeth 20. Restoration of the latching plate maintains the newly deflected teeth in registering position. The digits of a number are entered in sequence, the latching plates 33 being rocked in turn by staggered cams 8 on a shaft 4 advanced step-by-step by electromagnet 7. A digit is read out by feeler bars 11 which are urged upwardly by an electromagnet 15 acting through springs 12. The bars sense the teeth of a selected denomination through a corresponding coupling plate 40 having resilient teeth which when the plate is operative are positioned between teeth on the feeler bars and undeflected teeth 20 of the plates 19. Where a tooth 20 has been deflected, the feeler bar is able to rise. The coupling plates 40 are moved laterally to their operative positions in sequence by cams 9 arranged alternately with the cams 8 on the shaft 4. The feeler bars may control transmission links in a calculating machine as described in Specification 785,285 or may operate electric contacts 18.

Filed: 1974-06-26
Abstract: 1453348 Data processing systems INTERNATIONAL BUSINESS MACHINES CORP 26 June 1974 [2 July 1973] 28245/74 Heading G4A In a data processing system operating in a virtual memory mode, an I/O channel 10, Fig. 1, responds to a start I/O instruction to fetch a channel address word CAW which contains the virtual address of the start of a channel programme, the virtual address is translated to a real address by a channel look-aside buffer 14, the virtual address being stored in a virtual address stack 30, Fig. 2, in the buffer, and an interlock arrangement ensures that memory frames (pagesized real areas of memory) addressed by the channel cannot be accessed by the CPU. The interlock is provided in the channel look-aside buffer by an I/O bit array 32 which stores, for each memory frame, a count which is incremented or decremented each time a channel addresses that frame or finishes with that frame. As long as a request for access to a memory frame remains outstanding, the corresponding count is non-zero and an I/O summary bit reflecting the zero or non-zero status of the count is held in an insert storage key ISK in a storage protect area of memory in addition to other protect bits (parity, reference, change) used by the supervisor programme page relocation algorithm. Control information needed by the channel for the address translation process is held in an I/O control area I/OCA which stores a segment table origin address STO and translation control bits TCR. The virtual address stack 30, Fig. 2, holds the active data and command virtual addresses for each channel and is accessed by channel number and data/command bit, corresponding real addresses being stored in unit control words UCW for each channel. Comparison of a virtual address in I/OSAR with the virtual address in stack 30 appropriate to the channel concerned indicates whether or not address translation is required, and if it is, the operation is performed by reference to segment and page tables via the segment table origin STO, under the control of a translate ring counter 36.

Title: Improvements relating to the sorting or marshalling of railway vehicles
IPC: B60M1/10
Filed: 1920-01-10
Abstract: 166,476. Venables, R. E. S. Jan. 10, 1920. Electric locomotives.-A carriage travelling on a parallel path is temporarily engaged with a railway vehicle and, by engagement with sectional track conductors, controls the motion of the vehicle according as the next track section is vacant, as the points or other movable devices are correctly set, or as the vehicle has taken the correct road, or not. The carriage may travel underground and may act on the ordinary handbrake of the vehicle in a gravity system, or it may itself be arrested by brakes acting on its own wheels, or a. wheel geared thereto. The carriage may be self-propelled and may also propel the vehicle, and in the latter case the carriages described in Specification 162,322 may be used; and when an electric motor is used, it may be regenerative. Fig. 16 shows a carriage 3 running underground. The rails 4 are engaged by flanged wheels 7L and the rails 6 by plain wheels 7U, the wheels being carried by bogies 39 mounted on pivots 40, each pivot carrying a worm-wheel 44 driven by a worm 43, and pinion wheels 45, one engaging the wheel 7L direct and the other engaging the wheel 7U through a pinion 48. Adhesion of the wheels is increased by connecting the bogies 39 by links 42 with a spring 25 which carries at its centre a shackle engaged by a chain 59. Cables 5 lead fore and aft from drums 49, and are attached to the vehicle. Each drum is engaged by a pawl 51 on a lever 50 resting on a stop 52 adjusted by a screw 58. When the cable is unwound, lever 50 is raised and carries with it chain 59 to increase the spring load on the wheels. When the carriage is only used to arrest the vehicle, one end of chain 59 is fixed and the cable 5 on that side omitted. The carriage can be removed through covers 61 by releasing four bolts 68, flanges 69 supporting the wheels 7U in a path to disengage the gearing.

Abstract: 997,863. Centrifugal pumps. B.S.A. HARFORD PUMPS Ltd. July 22, 1963 [July 24, 1962], No. 28402/62. Heading F1C. In a centrifugal pump comprising a by-pass passage through which some liquid at elevated pressure is bled off and returned to the inlet leading to the impeller, the by-pass passage is so arranged that the by-pass flow issuing from the passage into the inlet has a directional component which is opposed to the direction of the main flow through the inlet, so that the by-pass flow physically opposes and thereby restricts the main flow through the inlet. A circulating pump for a central heating system is controlled by returning part of the flow to the inlet 2 via a by-pass passage 10, under the control of a manually adjustable valve 12. The by-pass passage 10 is located midway around the volute 4 and is inclined at approximately 15 degrees to the axis of the inlet. The by-pass flow enters the inlet 2 in counterflow to the inlet flow, whereby a throttling effect is exerted to restrict the inlet flow, thereby augmenting the normal by-pass effect in reducing the pump output. Rotation of the by-pass valve 12 towards the closed position alters the angle at which the by-pass flow discharges into the inlet 2, whereby the effect of the counterflow in throttling the inlet flow is reduced. The discharge angle may be fixed. Instead of being continuously variable, the by-pass valve may have two positions only. Alternatively, a by-pass passage with a fixed angle and a fixed flow may be provided.

Title: Improvements in and relating to movement and vibration dampers
IPC: F16F7/04
Filed: 1947-10-26
Abstract: 641,189. Vibration dampers. POWNALL, G. N. du T. Oct. 29, 1947, No. 28815. [Class 108(iii)] In a vibration damper of the kind comprising relatively rotatable friction elements, means for loading the friction elements by axially directed pressure consists of magnetic (preferably electro - magnetic) elements, which are capable of relative axial movement to form a substantially closed magnetic circuit. In the arrangement shown, an electro-magnetic element 25 including an electric winding 26 is in splined engagement through a bush 23 with a shaft 22 and cooperates with a second electro-magnetic element comprising a disc-like mild steel back plate 10, housing an electric winding 12. The shaft 22 is journalled in the back plate 10 and in a cover 18 secured thereto by bolts 16. Pairs of friction plates 27, 28 which are respectively splined to the periphery of the element 25 and slidably engage the bolts 16, cooperate with interspaced pairs of friction linings 29 and with further friction linings 29a, 29b, respectively located on a spigot 17 of the back plate 10 and against a pressure plate 30, non-rotatably clamped to the element 25. A ring 32 of bronze or other anti-friction material prevents facial contact between the element 25 and the back plate 10. Adjusting shims (not shown) may be inserted between the pressure plate 30 and the element 25. The windings 12 and 26 are energized through terminals 35 and 39 respectively which are connected to the windings through plug and socket connections and spring-loaded plungers and contacts, respectively, to facilitate removal of the cover 18 without disturbance to internal wiring. In the application to a damper between the chassis and axle of a vehicle, the windings 12 and 26 are energized from the vehicle battery, the. circuit including fixed and/or variable resistances whereby the friction elements may be loaded to varying degrees to suit running conditions of the vehicle. The number of friction elements may be varied to suit the type and weight of the vehicle., Mechanical means, such as springs, may be employed for supplementary loading of the friction elements. In a modification, the magnetic elements may comprise permanent magnets having' a winding or windings associated with one or both magnets. The damper is applicable to rail vehicles, recoil mechanisms on guns, rocket firing apparatus and industrial machine tools. The current to one magnetic element may be reversed and varied to vary the pull between the elements or to provide a reverse force between the friction elements.
