Title: Improvements in or relating to spooling arrangements for use, for example, in magnetic recording and reproducing apparatus
Inventor: DUTTON GILBERT FARADAY
IPC: G11B15/18
Filed: 1954-06-25
Abstract: 773,509. Sound-film or tape apparatus. ELECTRIC & MUSICAL INDUSTRIES, Ltd. June 13, 1955 [June 25, 1954; July 22, 1954], Nos. 18619/54 and 21368/54. Class 40 (2). In a magnetic tape record apparatus, the tendency for air to become trapped between the convolutions on the take-up spool is reduced by means of a resilient contacting member 12 arranged to press against the tape at a point in the proximity of the initial flexure of the tape as it is applied to the spool. In one embodiment, Fig. 1, the members 12 are mounted on arm 13 mounted on adjustable friction bearings 14, the point of pivotation being arranged as near as possible to the roller 6 or other point acting as the final guide means. Another embodiment is described with reference to Fig. 5 in which the arm 58 carrying contacting member 59 is mounted for rectilinear movement.

Abstract: 805,003. Turbines; centrifugal and axialflow compressors. ALLEN SONS & CO. Ltd., W. H., PERROT, F. C., and OXFORD, J. T. B. June 16, 1955 [June 25, 1954], No. 18716/54. Classes 110 (1) and 110 (3). An inlet duct for a gas turbine or compressor of the axial flow type or compressors of the centrifugal type wherein the gas enters the turbine or compressor casing laterally at one or more sides, i.e. transversely to the shaft axis and is led to a circumferential passage from which the flow is turned through approximately 90 degrees to enter the compressor or turbine blading through an annular approach passage, has the annular approach passage formed asymetrically either axially or radially or both relative to the rotor axis such that the lines of constant static pressure in the passage are inclined to a radial plane in such a manner as to produce acceleration of air or gas towards the region adjacent a lateral inlet and thereby reduce or counteract the whirl velocity in the inlet. In the axial flow gas turbine, Fig. 1, the combustion chamber 1 is connected with a circumferential passage or chamber 2 which communicates with the turbine blading 4 by an annular approach duct 5. This duct is longer at a point adjacent the inlet from the combustion chamber than at a diametrically opposite point. The radial dimensions of the duct are approximately uniform. Due to the inclination of the entry plane 8, the lines of constant static pressure are inclined in directions roughly parallel to the plane of entry. In a modification, as applied to a compressor, Figs. 6 and 7 (not shown), the entry plane 8 is at right angles to the rotor axis and the radial width of the duct is varied with the narrowest position adjacent the lateral inlet.

Abstract: 1,142,206. Welding arrangements. WELDING INSTITUTE. 29 April, 1966 [4 May, 1965], No. 18749/65. Heading H2H. A D.C. arc welding system has a principal power source having an output which does not fall cyclically to zero providing the major part of the arc current and an open circuit voltage of the same order as the arc voltage, and at least one supplementary power source connected in parallel having an output voltage which is greater than that of the principal power source and a short circuit current output not greater than 50% of that of the principal source. The sources may be derived from a battery, a generator or transformer rectifier combination, and in the latter case the output pulses may be phase shifted with respect to each other. A number of supplementary power sources of differing voltages may be employed, and a further source having an open circuit voltage which is low compared with that of the principal source and having a low impedance such that at short circuit its output current is materially higher than the output current of the principal source may be included. The principal source may include an impedance so that at the short circuit the further source current output is at least twice that of the principal source. The system may be used with consumable or non-consumable electrode arc welding and/or cutting arrangements. The principal source may also be replaced by two or more sources having differing open circuit voltages. Each source except that having the greatest voltage must have a reverse current preventing diode in series unless the sources already include rectifying diodes. The principal source may be of the type having pulses superimposed on a steady D.C. current and the supplementary source may be operative only over periods of expected instability.

Title: Improvements in road traffic control systems
IPC: G08G1/082
Filed: 1937-07-07
Abstract: 502,247. Road signals for controlling traffic. SIEMENS & GENERAL ELECTRIC RAILWAY SIGNAL CO., Ltd., DOWNES, F. A., HERWALD, N., and TYACK, F. G. July 7,1937, No. 18874. [Class 118 (ii)] In a system for controlling traffic at an intersection of at least three routes, in one mode of operation, traffic responsive devices in two of the routes are each adapted to effect a demand for a different right-of-way condition, while, in another mode of operation, both of the devices effect a demand for the same rightof-way condition. Thus, when traffic is light, the system may operate on a two-phase basis, and when heavy on a three-phase. The system is described as applied to a three-phase controller of the type described in Specification 427,832, embodying timer circuits of the type set forth in Specification 408,706. The controller may be part of a progressively controlled system such as is described in Specification 450,602, a degree of overlap of traffic conditions being provided to prevent the too frequent change from two-phase to three-phase working and vice versa. The change in number of phases may a a change in the cycle time as determined by the master controller. Three-phase to two-phase working. The controller operates as described in Specification 427,832 and it is assumed that the right-of-way is on road C. The tie line is energized, relays Z, J and relay group JA, JR, JG pulling up in turn, relay CY operating after J followed by relay CZ. prevents the Speed Timer operating during the conversion, also preventing a demand on B road from being effective, while CY and CZ cause an artificial demand to be made to maintain the right-of-way on road C. JA locks up JA, JR, JG and connects the B amber lamps to the A amber lamps; JR recompleting the Speed Timer circuit and connecting the B red lamps to the A red lamps, JG serving the same purpose for the green lamps. The relays associated with road B are now ineffective and the controller operates with two phases, pads in road B being connected in parallel with pads in road A. If right-of-way is not on road C, one of relays AR, BR is normal so that the relay group JA, JR, JG is not energized, when Z and J operate, but CY, CZ operate to give an artificial demand on road C by operating relay CD. Right-of-way passes to road C, when the conversion is completed. Two-phase to three-phase working. When the tie line is de-energized, Z and J release, and if right-of-way is on road C, relay CR will be normal so that JA, JR, JG release. CZ releases followed by CY which is slow to release, so that a pulse is sent to relay RW to maintain the right-of-way on road C until the conversion is completed. If right-of-way is on roads A and B, JA, JR, JG will remain operated as relay CR is operated. Artificial demand relays CZ, CY release to give an artificial demand, operating CD. The Speed Timer operates so that right-of-way passes to road C when the conversion is completed by relays JA, JR, JG releasing.

The system may be used for accumulating the charges incurred by using telephones, or (e.g. in hotels) TV sets, automatic dispensing devices, or the like. The data is received in the form of "charge pulses" (one per use of the device) on inputs FT1 ... FTN (Fig. 2) to an "interface matrix" IF containing N relay circuits Rr. Memory ME contains a section DA and units ... thousands sections MU ... MM (Fig. 3, not shown) linked to corresponding registers RSE and RSU ... (RSM). Each section MU &c. contains 1024-bit sections B1-B8 (for 1-, 2-, 4- and 8-weighted bits respectively) so that the charges from up to 1024 devices may be accumulated in ME in BCD form. IF and ME are addressed by a counter CA, the state of each relay contact r being scanned and transmitted to a multiplexer MX while the corresponding location in ME is accessed. To avoid errors caused by relay contact bounce or interference pulses, ME is only updated when a relay has been scanned four times and a 1100 result has been obtained: this is checked by AN in conjunction with DA and RSE, which respectively store the result of a current scan and of the previous scan. A 1100 result (LKJI) causes AN to transmit a 1-signal to the units section ADU of adder AD, which incorporates carry logic P5-P7 and co-operates with registers RSU ... to update the relevant total in MU... To ascertain the charges incurred by any peripheral device, its identity is entered on a keyboard CL and fed to a comparator CR connected to CA via a code converter TR: when the inputs to CR agree, ME is accessed and the required data is fed to a register RT, whence it passes via a multiplexing switch AM to a visual display VS. A printed tape output of the contents of ME may also be obtained, and there may be more than one device per location.
