Patent GB-2257732-A (GB)
Title: Anchor assembly
Inventor: MURRAY DONALD
IPC: E21B23/02
Filed: 1992-07-16
Abstract: An anchor is engageable by application of a downward load which allows collets 26 having a thread 14 form to engage a thread 12 form on a packer body 10. Further letting down on the tool locks in the collets 26 anchoring the tubing string. Release is accomplished by an upward pull which shears a ring 74 which frees the collets 26 for inward movement thereby allowing release from the packer body 10. An additional feature of the apparatus is that it permits initial engagement and disengagement of the anchor prior to locking of the collets. Thus, if insufficient tubing is available at the surface upon initial engagement with the packer, the tool may simply be pulled up to permit the addition of a pup joint at the surface. With the pup joint added, the string can then be lowered for latching leaving enough room at the surface to attach the tubing hanger. <IMAGE>

Title: Method and apparatus for automatically identifying a program including a sound signal
Inventor: FARDEAU MICHEL
IPC: H04B17/00
Filed: 1992-09-22
Abstract: A method and apparatus for automatically identifying a program broadcast by a radio station or by a television channel, or recorded on a medium, by adding an inaudible encoded message to the sound signal of the program, the message identifying the broadcasting channel or station, the program and/or the exact date. In one embodiment, the sound signal is transmitted via analog-to-digital converter (12) to a data processor (14) enabling frequency components to be split up, enabling the energy in some of the frequency components to be altered in a predetermined manner to form an encoded identification message, and with the output from the data processor (14) being connected via a digital-to-analog converter (26) to an audio output for broadcasting or recording the sound signal. In another embodiment, an analog bandpass filter is employed to separate a band of frequencies from the sound signal so that energy in the separated band may be thus altered to encode the sound signal.

Title: Electrical connector for PCB's
Inventor: CHEN CHOU LIN
IPC: H01R12/70
Filed: 1992-11-11
Abstract: An electrical connector which has a housing (13) with a first surface (6) for mounting a mother board (10) and a second surface (7) for mounting a daughter board. On both ends of the first surface (6) there are mounting legs (130) for receiving an edge of the mother board (10). On both ends of the second surface there are latch members (120) for holding the daughter board and stoppers (122) slightly spaced from the latch members (120). When the daughter board is mounted on the connector, the latch members (120) are prevented from being flexed excessively due to the contact of the latch members with the stoppers (122). Alternatively, the first surface may be attached to a pcb by soldering pins. The daughter board may be received parallel to the mother board or at an angle to it. The latches may be separatable metallic pieces. <IMAGE>

Title: Video camera fade control.
Inventor: NA WOON-HEE
IPC: H04N9/74
Filed: 1992-12-09
Abstract: The apparatus generates a blanking area of blue colour having a triangular shape in each corner of the video image for fading-in or fading-out a video image obtained from video camera 1. Four coordinate determiners 70 - 76 are provided to calculate the coordinates of the transition between the video image and the blanking area which are connected to four area generators 80 - 86. These control blue screen generator 9 to produce the blue blanking area as required. The effect is progressive, the blanking area increasing in size for fade-out, and decreasing for fade-in, controlled by switches 5 and 6 respectively. <IMAGE>

Title: Method and apparatus for estimating the doppler frequency of a mobile station
Inventor: DAHLMAN BENGT ERIK LENNART
IPC: G01S11/10
Filed: 1993-03-16
Abstract: A method and apparatus for approximating the doppler frequency of a mobile station (M1-M9) by examining the signal between the mobile station (M1-M9) and a base station (B1-B10). Several channel estimates (hj(n)) are calculated at different intervals (t1, t2) for the signal between the mobile station (M1-M9) and the base station (B1-B10). The difference (Vj(n)) between these channels estimates (hj(n)) is used to determine the approximate doppler frequency of the mobile station (M1-M9). A cellular mobile radio system can use the doppler frequency of the mobile station (M1-M9) to prioritize a handoff queue or to select an appropriate detecting algorithm for detecting data in a received signal (r(t)).

IPC: A41H3/00
Filed: 1993-03-17
Abstract: Method of and apparatus for generating two- and three-dimensional surface meshes and for unwrapping and flattening three-dimensional pattern shapes is based on a computer-assisted design system. Thus a three-dimensional surface (R) Figure 4 defined by parametric spline patch surfaces joined at surface boundaries with at least one edge (E1, E2) defining a discontinuity in said surface and with at least one vortex (V1-V3) defining a point on said edge is mapped to a flat plane by growing a regional mesh (Figure 5a) on the surface conforming to its topology independently of said boundaries, the mesh coinciding with and spanning the mathematical definition of the surface and having nodal points interconnected by links defining triangular or other polygonal elements therebetween. Said elements are mapped to a flat plane and assembled in two-dimensional shape. The elements are initially aligned either side of the edges with the remaining spaces then being filled under operator supervision. <IMAGE>

Title: Erasing the optical characteristics of a display field on a carrier e.g. a telephone card.
Inventor: DSCHEN TSING
IPC: B42D25/00
Filed: 1993-08-06
Abstract: A carrier (1) for display fields (3) or value characters, such as a credit means in the form of a telephone card, contains optically readable display fields (3) which can be erased by the effects of heat or which can at least be changed permanently in optical terms, and a storage layer (5) for storing energy for the purpose of producing the thermal energy required for the heating effect at the location of the display field (3) to be erased. In this way, the energy stored in the storage layer (5), which energy corresponds to at least the erase energy required, is released by the supply of an initial energy which is less than the erase energy. If a photoconductive layer (9) is used additionally, the reading light beam (13) can also serve to produce a local electrical current I in the region of the display field (3) to be erased, wherein the current I produces sufficient thermal energy in the form of initial energy to set in motion the reaction process in the storage layer (5) and to release the thermal energy stored therein. The storage layer (5) is a pyrotechnical material. <IMAGE>
