Title: A distance measurement system
Inventor: WEBSTER DAVID JOHN
IPC: G01S15/08
Filed: 1992-03-23
Abstract: Apparatus and a method using ultrasonic signals to determine the distance between the displacement of two points in space. An ultrasonic distance measurement unit (1) generates frequency modulated ultrasonic waves using binary shift keying. The signals are transmitted by the transmitting transducer (2) towards a reflector assembly (30), preferably comprised of two reflectors (31, 32). One of the reflectors (31) is smaller than the other reflector (32), and the smaller reflector (31) is positioned in front of the larger reflector (32). The reflected signals are received by the receiving transducer (3). The unit (1) phase digitises and processes the received signal by recording time stamps of zero-crossings of the received signal. The speed of sound may be determined by a temperature measurement system (5) and/or by measuring the transit time difference between the two reflectors (31, 32) of the assembly (30). The distance between the unit (1) and the assembly (30) can then be determined from the speed of sound and the time taken for an ultrasonic signal to travel between the unit (1) and assembly (30). Displacement of the assembly (30) relative to the unit (1) can be determined by making distance measurements over a period of time. The present invention has a number of applications, including measurement of roof convergence in underground mining.

Title: Producing a thermal insulating panel
Inventor: MCLOUGHLIN JAMES ANTHONY
IPC: F16L59/02
Filed: 1994-02-24
Abstract: A thermal insulating panel is manufactured from a substantially rectangular sheet (11) of porous material by folding the sheet over on itself to bring a pair of opposite edges (12, 13) into overlying aligned interfacial engagement with one another and securing the overlying edges together along the interface therebetween to form a tubular member having a seam extending in an axial direction. The tubular member is then flattened to form two opposed closed side edges (15, 16) extending in the axial direction and two lateral opposed open side edges (17, 18), the seam being positioned intermediate the two opposed closed side edges. One of the two open side edges (17) is then closed to form an envelope open along one side edge (18) and particulate thermal insulating material is introduced into the envelope through the open side edge which is then closed. Pressure is applied to the exterior of the envelope to consolidate the insulating material and to form a substantially rectangular panel having two opposed side edges (15, 16) neither of which contains the seam. <IMAGE>

Title: Image synthesizer
Inventor: MURATA HIROYUKI
IPC: G06T15/04
Filed: 1993-08-26
Abstract: An image synthesizer which can output a high quality texture-mapped image on a real time basis without hindering the high-speed operation and downsizing of hardware. A three-dimensional image is formed by a game space setting portion (13) and an image supply portion (10), and predetermined three-dimensional arithmetic processing is executed. Coordinates of each dot inside a polygon and texture coordinates corresponding to the former are determined by a processor portion (30). The texture coordinates are stored at an address of a field buffer portion (40) designated by the coordinates of each dot. Predetermined rendering data is stored in a texture data memory portion (42). The texture coordinates are read out from the field butter portion (40), while the rendering data is read out from the texture data memory portion (42), so that a pseudo-three-dimensional image is synthesized and outputted. When the texture coordinates are stored in the field buffer portion (40) in this way, thinning-out/interpolation operation, etc., can be executed. <IMAGE>

Title: Optical network traffic protection system
Inventor: OKA AKIHIKO
IPC: H04B10/077
Filed: 1994-10-17
Abstract: A failure detector (31), connected to receive a signal (DS1, DS2, DS3) from an interface lower level than the SONET level, detects a failure in that interface, such as a fiber cut or the loss of signals. An Alarm Indication Signal (AIS) generator (32) is responsive to the detection of a failure by the failure detector to generate an AIS at the SONET level (STS and VT levels). A signal processing circuit (33) converts a low-level signal from the interface to a SONET-level signal. When receiving the SONET-level AIS from the AIS generator, the signal processing circuit inserts it onto the SONET-level signal for application to SONET Add/Drop Multiplexers (ADMs). In a network which comprises multiple SONET path protection switching (PPS) rings that are connected together with interfaces at a level lower than the SONET level, such an arrangement can enable path switching to be triggered effectively even in the event of failures in the interfaces, thereby promoting the preservation of signals. <IMAGE>

Patent GB-944941-A (GB)
IPC: G03G13/22
Abstract: 944,941. Electrophotography. PHOTOSTATIC ENTERPRISES Ltd. Nov. 16, 1959 [Nov. 17, 1958], No.38821/59. Drawings to Specification. Heading G2H. [Also in Divisions B5, B8 and H1] A transferable film bearing an electrophotographically-produced visible image, e.g. a label, is produced by coating a base with a temporarybond coating, which is such as to allow a charge to leak away, applying over this a photoconductive insulating film, and, after forming electrophotographically an electrostatic pattern on the photoconductive film, developing the pattern with a developer carrying a pigment substance, and finally stripping the image-bearing film from the base by destroying the temporary bond. By repeating the image-forming and developing steps multicolour images may be obtained. Before or after stripping the photoconductive film bearing the developed image from the base a sealing layer may be applied over the image-bearing film. The base may be of aluminium foil with or without a paper backing, metal, plastic, glass, wood, paper, hardboard or cloth; the temporary adhesive may be animal glue, natural gums and resins, polystyrene, waxes, mineral oil, animal or vegetable fats, greases or oils; and the photoconductive insulating film may be of lead, lead oxide, lead iodide, cadmium selenide, bismuth trioxide, zinc oxide or selenium particles dispersed in a film-forming binder comprising cellulose or cellulose esters or natural or synthetic gums or resins, especially alkyd, silicone, or epoxy resins. The photoconductive film may contain also lead or cobalt naphthenate driers and may also include rutile as an opacifying pigment. The developer may comprise a pigment such as carbon, carbon black, cadmium selenide or cobalt oxide, an alkyd or silicone resin, and cobalt and lead naphthenate driers ball-milled to form a pigment-in-resin dispersion which is itself then dispersed in an insulating liquid such as petroleum solvents, n-pentane, cyclohexane, and fluorochloro-ethanes or -methanes. The sealing layer may be an unpigmented layer of the filmforming synthetic resins specified for the photoconductive film, and may be a preformed layer secured by an adhesive over the image. The image-bearing film may be secured to any desired surface such as a preserving can by applying an adhesive to the surface of the photoconductive film from which the base has been stripped.

Patent GB-2285999-A (GB)
Title: Parallel seal assembly
Inventor: KENNEDY BRIAN S
IPC: E21B33/122
Filed: 1995-01-26
Abstract: A scoophead/diverter assembly functions to orient and anchor multiple tubing strings at the Y juncture in an oil or gas well with multiple lateral wellbores. The large bore of the scoophead enables a secondary wellbore's production tubing (liner) to pass through until the top of the liner is in the scoophead. In order to effect a seal inside the scoophead, an offset parallel seal assembly with centralizer is utilized. This parallel seal assembly carries compressive loads on the primary wellbore side, and has a shear out mechanism (440, 442) on the secondary wellbore side. This seal assembly also may constitute the connection between the scoophead and a selective re-entry tool (SRT). The SRT is a tool that ties the two separate tubing strings below it into a single production tubing string to surface or the next lateral. This parallel seal assembly has two seal assemblies (382, 384) parallel to one another with one seal assembly being of larger diameter and longer than the other. The larger seal assembly (382) seals into the seal bore of a tie back sleeve which is latched into the scoophead, and is attached to the top of the secondary wellbore's production tubing string. The smaller seal assembly (384) seals in the small bore of the scoophead. The smaller assembly (384) acts to isolate the primary wellbore. The larger seal assembly (382) is longer than the smaller to allow it to enter its bore and align the assembly. The alignment is accomplished by trapping the larger seal assembly (382) in its bore and trapping the centralizer (386) in the wellbore. This positively limits the rotational misalignment available to the smaller seal assembly (384) prior to stabbing into the scoophead. <IMAGE>

Title: Asymmetric divergent projection system
Inventor: COLCLOUGH ROBIN CHRISTOPHER
IPC: G02B17/00
Filed: 1995-03-02
Abstract: The asymmetric divergent projection system has a colour or monochrome film, CRT, LCD or similar image projection device, an asymmetrical divergent lensing mirror/s or lens/es and an image projection screen. The image is focused onto the screen using an asymmetrical divergent lensing mirror/s or lens/es whose asymmetric convex shape expands the image, optically compensating for the geometric image distortion caused by the varying focal length (A* has a higher rank than; succeeds *B) occurring with the mirror/s being placed off screen-centre to project the image across the full front area of the unit's housing. Distortion compensation is achieved by graduating the angle of reflection, or refraction for a lens, over surface of the divergent mirror or lens such that the image is equally projected across the surface of the screen to match the optical paths shown as B, C and A.

Title: Frequency-sensitive control of beamwidth an acoustic transducers
Inventor: POWER JEFFREY
IPC: G10K11/18
Filed: 1995-12-12
Abstract: The present invention proposes a transducer in which automatic frequency-sensitive control of the beamwidth is provided by frequency-dependent "shading" of the local response to the signal across the face of the element. This is achieved by using a resistive coating 21, in association with a capacitive layer 22, with the currents representing the acoustic signal travelling through the resistive layer. Due at least in part to the central position of the contact to the resistive layer the CR value of the combination varies over the surface of the element. The capacitive layer may be a piezoelectric ceramic or polymer material or an air layer. A multilayer embodiment is shown in fig. 8. This technique is useful in Sonar or Hi-Fi applications. <IMAGE>
