Title: Endoscope optical system
Inventor: LAYCOCK LESLIE CHARLES
IPC: A61B1/002
Filed: 1995-06-03
Abstract: An endoscope comprises an optical system for forming an image of e.g. organs inside a patient's body, and a relay system e.g. optical fibres, for relaying the image. The optical system 1 produces peripheral pixels of the relayed image which correspond to a greater field of view of the object than the central pixels of the relayed image correspond to. This may be achieved by a lens 8 which has a greater magnifying power at its optical axis than at its edges or by arranging that peripheral optical fibres of a relay system accept a greater field of view than central fibres (Fig. 3).

Title: Gaining access to subsea oil wells
Inventor: HEAD PHILIP
IPC: E21B41/10
Filed: 1995-09-11
Abstract: A guide arrangement 3 for gaining access to an underwater well comprises buoys 4, a connecting frame (5) and guide lines 12 extending from the lower end of the buoys 4. The guide arrangement 3 may be lowered by means of a wire support or coiled tubing 6 from a surface vessel (8) and when it is in position a remote vehicle 22 is used to connect the guide lines 12 to the well head 2.

Title: A chain roller having grooves which prevent axial expansion when the roller is pressed through a sizing die
Inventor: OTANI TOMOFUMI
IPC: B21D3/14
Filed: 1996-01-30
Abstract: A chain roller 16 is manufactured from cut strip steel (10, figs 1 and 2) into which blind grooves 22 have been, for example, rolled-formed. The strip is formed into a cylindrical shape, with the grooves on the inside, and then the unsized roller 16 is pressed through die 20. Grooves 22 plastically deform, as the roller 16 passes though the die, which prevents the roller from increasing in length. The shape, number and orientation of the grooves 22 may be varied (see figs 10 to 12). When being assembled to form a chain the roller (24, fig 5) is press-fitted into inner plates (26, fig 5) and a pin (28, fig 5) is inserted through the roller. Lubrication pockets are created by the grooves (see figs 6 to 9). The roller may be used as a bushing fitted into a roller made of resin provided in a centre roller chain or a top roller chain.

Title: Slide driving apparatus for mechanical press
Inventor: SATO MITSUO
IPC: B30B1/26
Filed: 1996-07-16
Abstract: A mechanical press has a drive shaft to which power from a motor is transmitted through a transmission system including a flywheel 3 and a clutch. A pinion on the drive shaft drives a drive gear 5 fixed to a crankshaft 6 which provides a reference phase. The crankshaft 6 drives a reference slide 8. The drive gear 5 drives a driven gear 9, 11 provided on each of other crankshafts 10, 12 which drive different slides 15, 16 in the mechanical press. Each driven gear 9, 11 is disengageable from the drive gear 5. After disengagement, the rotational phase relation between a drive gear 9, 11 and the drive gear 5 can be changed and, thereafter, the drive gear 9, 11 be brought again into engagement with the drive gear 5. The sequence of the pressing steps to be performed by the different slides, as well as the phase differences, are thus determined and set so as to ensure that each step can be performed without being affected by the pressing operations which are being performed by other slides.

Title: Holder for cellular phone
Inventor: KIM DONG-JOO
IPC: H04B1/38
Filed: 1996-11-19
Abstract: In a holder for cellular phone, a button 48 on the rear of a phone case 42 is releasably retained by a spring-loaded detent 60 in the lower end of a slot 59 provided in a cover member 58 secured to a base member 52 which itself can be clipped to a user's belt. The slot 59 is shaped to cooperate with the button when retained to limit the rotating angle of the cased cellular phone relative to the holder, thus preventing a sudden separation of the cellular phone from the phone case. In an alternative construction the case and holder are integrated, and the holder has means for limiting the rotating angle of a phone case relative to the holder, thus allowing the phone case to be rotated freely or within a limited angle relative to the holder. In a further construction the base member is a bracket fixed to a support eg in a vehicle.

Patent GB-2313497-A (GB)
Title: Lithium cell recharging
Inventor: PALMORE SEAN FRANCIS
IPC: H02J7/00
Filed: 1997-02-27
Abstract: Overcharge of the weaker cells in a battery of series connected lithium ion cells S, charged with a current limited constant voltage, is prevented by providing each cell S with a protection circuit 10 which has a bypass circuit 12 including a MOSFET T and a resistor R1. If the design voltage of a cell is exceeded, an integrated circuit voltage comparator Y turns on the MOSFET via a filter circuit 16 to bypass a minor part of the charging current through the resistor R1, the major part of the charging current still flowing through the cell. The bypass current only flows while each of the other cells are coming up to design voltage so that little power is thereafter dissipated in the bypass circuit 12 when the MOSFET T is off. The circuits 10 can thus remain connected to the cells at all times. The bypass current may be between 10mA and 200mA, and is no more than 10% of the charging current.
Patent GB-2315346-A (GB)
Title: Approximating trigonometric funtions using look up tables and quadrant bits
Inventor: TAKAHASHI HIDEAKI
IPC: G06G7/22
Filed: 1997-07-16
Abstract: The device uses two look up tables to calculate the sine or the cosine of an angle, the angle being represented in binary format. The two most significant bits indicate the quadrant of the angle, i.e. 0-90{, 90-180{, 180-270{ or 270-360{. The remaining bits of the angle are used as an address to read values from two look up tables, one storing modulus values for the sine function in the range 0-90{, the other storing modulus values for the cosine function in the same range. The most significant bits are then used to determine whether the value from the cosine or the sine look up table is used for the function value and are also used to determine the sign of function value.

Title: Exponentiation Circuit Utilizing Shift Means and Method of Using Same
Inventor: BUSS JOHN MICHAEL
IPC: G06F7/552
Filed: 1996-01-29
Abstract: A circuit and method for computing an exponential signal x 8 is provided. The circuit includes a logarithm converter (4) which converts an input signal to binary word that represents the logarithm of an input signal x. A first shift register shifts (8) the binary word in a bit-wise fashion to produce a first intermediate value; while a second shift register (28) shifts the binary word in a bit-wise fashion to produce a second intermediate value. The shift registers may be implemented using multiplexers. The shifting operations are equivalent to multiplying the intermediate values by a factor which is a power of two. The first intermediate value is either added to or subtracted from the second intermediate value to produce a combined value. An inverse-logarithm converter (34) converts the combined value to the exponential signal.
