Title: Anchor system
Inventor: LIEM SYLVESTER
IPC: B25B13/48
Filed: 1995-05-25
Abstract: A chemically-set anchor system comprises a female anchor (2) with an internally beaded bore, a capsule (not shown) containing resin and a hardener, and a setting tool (4) which fits into the bore in the anchor (2). The capsule and anchor are inserted into a hole drilled into masonry, and the setting tool (4) is coupled to the anchor (2) by a connection (14, 16) which permits torque to be transmitted from the tool (4) to the anchor (2) whereby rotation of the anchor (2) breaks the capsule and mixes the resin and hardener. The connection (14, 16) is such that the setting tool can then be withdrawn from the anchor by simple axial movement without applying torque to the anchor (2), and without waiting for the adhesive to harden. The connection may be a drive pin (14) on the tool (4) engaging slots (16) in the anchor (2), or vice versa. Alternatively, the bore of the anchor (2) may be a square or hexagonal in cross-section, for engagement by a corresponding profile on the tool (4). The free end of the shank (12) may carry a spring clip (not shown) to frictionally hold the anchor (2) on the tool (4). <IMAGE>

Title: Position controller for a servo drive
Inventor: KARTE THOMAS
IPC: F15B13/043
Filed: 1995-07-31
Abstract: A position controller for a pressure medium-operated servo drive with a pilot stage (6, 7, 8) based on the principle of current/pressure conversion (I/P conversion), preferably a pneumatic pilot stage, and a main stage (5) which can be actuated through the latter and by means of which a final control element (1) can be acted upon by a pressure medium to execute a control movement, the pilot stage comprising an electronics unit (2) by means of which the pilot stage can be actuated. In order to be able to produce rapid venting of the pressure medium with the "intrinsically safe" type of ignition protection, the invention proposes that in the electrical actuation path between the electronics (2) and the pilot stage (6, 7, 8) there is a switching element (13) which cuts the electrical actuating signal to the pilot stage in the event of a malfunction, and in that in this case the pilot stage adopts a fail-safe position such that the control volume (1) of the final control element is vented through the main stage (5). <IMAGE>

Title: Electro-magnetic radiation isolator
Inventor: MACKAY ANDREW JAMES
IPC: H01Q15/24
Filed: 1996-06-24
Abstract: An electro-magnetic radiation isolator (10) for microwave or millimetre-wave frequencies, comprises a Faraday rotator (20) sandwiched between two polarising layers (22, 26, 30 & 24, 28, 32). Each of the polarising layers comprises an array of high conductivity linear strips (30, 32) separated from an array of resistive strips (22, 24) by a quarter wavelength dielectric layer (26, 28). Radiation incident on one side of the isolator with its electric vector orthogonal to the strips passes through a first polarising layer with little attenuation and has its polarisation rotated by the Faraday rotator. The second polarising layer is arranged so that this radiation is then able to pass through the second polarising layer with little attenuation and hence is transmitted by the isolator with a relatively high transmission coefficient. Incident radiation which is incident on the other side of the isolator may either be reflected or absorbed in the isolator, and hence has a very low transmission coefficient.

Patent GB-968831-A (GB)
Abstract: 968,831. Flexible tubes. A. C. ANSELM. Nov. 24, 1960 [Nov. 25, 1959], No. 39987/59. Heading F2P. A method of making a tube which is externally corrugated and has a substantially smooth bore, comprises the steps of winding around a mandrel a reinforcing wire covered with or constituted by a thermoplastic material to form a reinforcing helix 2 with adjacent turns spaced apart, helically winding a flat tape 3, of a material having at least one face thereof constituted by a thermoplastic material, around the helix so that the edges of the tape overlap, heating the thermoplastic of the tape to soften the plastic to a temperature required for welding and then deforming the tape while softened, by radially-acting forces, around the helix to weld the overlapping edges of the tape and the helix together and thereby form a corrugated tube with the portions of the tape intermediate the turns of the helix lying substantially on the same diameter as the internal diameter of the helix. As shown, the tensioned strip 3 passes over or through a guide 4 on to the helix 2 which is mounted on a mandrel 1 and the overlapped edges of the strip are heated by hot air jets 6. Deformation of the strip is assisted by a grooved roller 7 or a stationary, inwardly profiled jacket, and a wire or thread or electrical conductor 9 is wound around the tube and welded in position by a hot, air jet 6a. A device for controlling the tension of the strip is incorporated in the apparatus. The tape and helix may be simultaneously wound on to the mandrel. The tape may consist of laminations bonded together before or after winding on to the helix, and the tube may be formed of two helices and two or more tapes. The helix may be of a thermoplastic material or consist of a metal covered with thermoplastic material, and the tape may consist of a thermoplastic material such as polyethylene, polyvinyl chloride or a polyamide and have fabric, threads or fibres embedded therein, a metal foil having a paper lamination on both sides thereof and at least one of the paper laminations being coated with or laminated with a layer of thermoplastic material, or a paper laminated with a thermoplastic material such as polyethylene. Preferably, the turns of the helix lie beneath the overlapping edges of the tape.

Title: A coated superalloy article
Inventor: MEELU MEHAR CHAND
IPC: C23C10/58
Filed: 1997-02-22
Abstract: A superalloy article 20 has a multilayer coating 22 comprising a chromium, titanium and/or tantalum and silicon enriched layer 24, a platinum aluminide coating 26, an alumina layer 28 and a ceramic thermal barrier coating 30. The platinum aluminide coating 26 is a very good corrosion and oxidation protective coating for the superalloy article 20. The chromium and silicon enriched layer 24 prevents silicon in the platinum aluminide-silicide coating diffusing to the superalloy article 20 to minimise the formation of silicon rich topologically close packed phases at the interface between the superalloy article 20 and the multilayer coating 22. The system forms a good bond coating for the ceramic thermal barrier coating 30. The chromium, titanium and/or tantalum may be applied by chromising or sputtering. Additional steps include depositing yttrium, zirconium or erbium.

Title: Torque down control apparatus involving switching of fuel cutting to cylinders
Inventor: MATSUKI YOSHITAKA
IPC: F02B75/22
Filed: 1997-09-30
Abstract: An engine has two barks of cylinders 1a, 1b, and a catalyst 2a, 2b in the exhaust path from each bank of cylinders 1a, 1b. When a fuel cut requirement signal is generated, for instance when wheelslip is detected, 11, a corresponding fuel cut to a number of cylinders is carried out. Cylinders in which the fuel is cut are controlled to be switched between right and left banks 1a, 1b. For example, when there is a requirement for a fuel cut with respect to two cylinders, then two cylinders in the right bank 1a have their fuel cut for a predetermined time, and then two cylinders in the left bank 1b have their fuel cut for a predetermined time, and this operation is repeated during a continuing time of the required fuel cut. A different combination of two cylinders can be used each time the fuel is cut in a particular bank (figure 8). Accordingly, any thermal damage due to the fuel cut is not concentrated on only one catalyst. Various switching patterns may be employed (figure 5) using various numbers of cylinders.

Title: Pipe lifting device
Inventor: MCCORMICK DAVID JOHN
IPC: B66C1/62
Filed: 1998-03-26
Abstract: A pipe lifting device comprises a pin having an elongated shaft portion 10 and at one end a pivotable gravity operated latch 22 eg a toggle having two unequal length arms 23,25 (11, 12 Fig.1) which operates to prevent unintentional withdrawal of the shaft from a hole in a section of pipe, and at the other a means for attaching lifting means 12. In use, the latch is aligned longitudinally with the shaft and stopped by a chamfered face 26 against a stop surface 24 (see Fig.2). The latch and part of the shaft may then be inserted into a hole in a section of pipe and the shaft rotated through 180' about its longitudinal axis to cause the latch to pivot due to gravity into a position perpendicular to the shaft so as to be retained within the pipe (Fig.1). Removal of the lifting device may be effected by rotating the shaft through a further 180‹ such that the longer arm pivots due to gravity and the shorter arm is stopped, thereby aligning the latch with the shaft and preventing further rotation of the latch. The latch may include an insert of denser material at one end to enhance the latching action, in which case the latch arms may be of equal or unequal length.
