Patent GB-2226520-A (GB)
Title: Extruding a continuous polymeric encapsulant of varying composition over a metal line
Inventor: HOWELL BOBBY O
IPC: B29C48/49
Filed: 1989-12-12
Abstract: The metal line is suitable for transmitting signals or injection of chemicals in a hostile subterranean environment. The encapsulant is continuously extruded as sequential sections, comprising a first nylon-based material section and a second fluoropolymer-based material section, and an intermediate section wherein the composition of the encapsulant is a composite of varying percentages of the nylon and fluoropolymer-based materials. The metal line is preheated so that the extruded polymer does not stress crack, and the composite material is extruded at a temperature substantially above the melting point of nylon. and is fluid cooled to delay crystallisation. The encapsulated tubular metal line is suited for transmitting fluid through a petroleum recovery well bore having a corrosive fluid wherein the temperature in the well bore varies with depth. The continuous extrusion between the different sections, avoids the leakage that might otherwise occur, between seals at the section junctions.

Title: Dual frequency sonar transducer assembly
Inventor: STEARNS CLEO MILFORD
IPC: B06B1/06
Filed: 1989-12-19
Abstract: The assembly may be operated at low and/or high frequencies in a sonar array. It comprises a low frequency unit of tonpilz design including a low frequency driver 18, a low frequency tail mass 19 and a composite head mass 16, the composite head mass acting as a single low frequency water driving piston and comprising a plurality of high frequency units 25 forming individual high frequency water driving pistons. The high frequency units are also of tonpilz design, with independent drivers 24, independent head masses, and a common tail mass 22. The use of a common tail mass simplifies the design without compromising high frequency operation. The design leads to more efficient operation at both frequencies by minimizing the head mass to tail mass ratios.

Title: Compression indicating device
Inventor: CENEY DAVID JOHN
IPC: F16B31/02
Filed: 1990-03-30
Abstract: A compression indication device for replacing torque spanners, load cells etc. comprises a member 18 carrying a stud (26) which is positioned such that when a compressive force is applied to the member (18) by tightening a nut (14) on a bob (16), it eventually contacts a compression washer (20) when the washer (20) reaches a deformed position in which it exerts a desired force on an assembly of flat plates (10, 12). An electrical circuit is completed through the stud 26 and washer 20 and a bulb (30) lights, thus indicating that the desired load has been achieved. The stud 26 comprises a conductive core spaced by an insulating sleeve from an outer threaded portion engaging in a threaded hole in member 18. A spring loaded ball in the core contacts washer 20 and prevents excessive force on the stud. In an alternative arrangement the stud is made entirely of metal and is secured by nuts in an insulating liner in the member. The device may be applied to a friction welding machine to ensure that the workpieces are compressed together at identical pressures despite size variations. <IMAGE>

Title: Wide-band clip for connecting pipes and process for the production thereof
Inventor: STICHEL WILLI
IPC: F16L33/04
Filed: 1990-11-28
Abstract: A wide-band clip for connecting two pipes or the like comprises a clamping band (1), to the end portions of which, on the outside thereof, are secured clamping jaws (5) having flanges (9) which are bent away from the clamping band and which can be pulled towards each other by means of a screw connection (12), and limbs (7) extending over a part of the periphery of the clamping band. Each limb (7) forms with the end portion bearing thereagainst a positive connection in which a tongue (15) which is delimited by a respective substantially U-shaped incision in the end portion (3) extends through at least two transverse slits (16) in the clamping jaw limb (7). The length of the transverse slits (16) and the width of each tongue (15) are at least a quarter of the clamping jaw width. That provides a connection between the clamping jaws (5) and the clamping band (1), which is highly resistant to a tensile force applied thereto. In the production of the wide-band clip, prior to the introduction of the tongue (15) into the transverse slits (16), the web portions (27, 32) which are defined by the transverse slits are pressed alternately out of the plane of the limb above the one surface of the limb. The tongue (15) is then introduced into the transverse slits (16) and then the web portions (27, 32) are pressed back into the plane of the limb again, causing deformation of the tongue. <IMAGE>

Title: Radiation pyrometer
Inventor: WATSON JEFFREY
IPC: H04N5/335
Filed: 1991-12-11
Abstract: A radiation pyrometer has four rectangular photodiodes 21 to 24 mounted in an orthogonal array 20. Radiation from a hot body 2 is focussed as a circular image 25 centrally of the array. The outputs of diagonally opposite photodiodes 21 and 23, and 22 and 24 are connected together to form two identical output channels. The output of each channel is insensitive to displacement of the image 25' since the resulting decrease in coverage of one photodiode 22 (or 23) is compensated by the increase in coverage of the other photodiode 24 (or 21) of the pair. <IMAGE>

Title: System, used in scheduling or the like, for satisfying constraints
Inventor: TANAKA TOSHIKAZU
IPC: G06F19/00
Filed: 1992-10-09
Abstract: In a system, utilized in, e.g., scheduling of machine use, for satisfying constraints, a section 3 detects necessity of constraint relaxation in a problem solving cycle of a section 1. When the necessity is detected, a section 4 is enabled to select a target constraint to be relaxed from a constraint group. A section 5 searches a constraint relaxation knowledge management section 2 in association with the selected constraint to check if a partial solution satisfies a relaxation permission condition. If the condition is satisfied, constraint relaxation is attempted according to a relaxation method recorded in correspondence with the condition. When the constraint relaxation is executed, section 3 checks if the result is successful, and control returns to the problem solving cycle of section 1. <IMAGE>

Title: Data memory with power-saving access control
Inventor: HOWARD DAVID WILLIAM
IPC: G06F12/0802
Filed: 1993-09-27
Abstract: A data memory is described in which data words comprising access control bits and further bits are stored at each memory location. When a particular memory location is addressed, 4, then the access control bits stored at that memory location are output, 8, to control logic 12 that serves to generate a valid access signal. The valid access signal is fed back to the selected memory location and controls 16, 18, whether the further bits stored at that memory location are output 10. If access to those further bits is not permitted by the access control bits, then the further bits are not output and power is saved by not having to drive bus lines. The control logic is responsive to hardware and software flags in addition to the access control bits. The system is particularly suited for use in conjunction with a cache memory (as shown) or a RAM (Fig. 6). <IMAGE>
