Title: Rotary positive displacement supercharger
Inventor: SAYAMA MASAYUKI
IPC: F04C28/26
Filed: 1996-05-24
Abstract: In a supercharger for supplying air to an engine a casing 13 has a suction opening 31 at an inlet end of the casing and a discharge opening 33 at the opposite end thereof, rotors 15, 17 compressing air introduced via the suction opening 31 to supply the engine, via the discharge opening 33. The casing 13 has therein a by-pass passage 19 for establishing communication between the suction opening 31 and the discharge opening 33, a by-pass valve 21 to open and close the by-pass passage being operated by an actuator 43. The supercharger is driven via an electromagnetic clutch 5. The valve 21 may be opened by the actuator 43 to supply air to an engine via the by-pass passage 19 when the supercharger is not driven and to allow recirculation of air from the discharge opening 33 to the suction opening 31 when the supercharging pressure exceeds a predetermined value. When the valve 21 is closed air is supplied to the engine via the supercharger.

Title: Communication Equipment with Transmission Rate Regulating Function
Inventor: TANAKA MASAHIKO
IPC: H04L1/00
Filed: 1996-07-25
Abstract: An RSSI detector detects the level of the electric field of a received signal, and an initial value of the transmission rate is determined from the detected level of the received electric field. A radio circuit transmits the determined initial value to a base station and in response the base station transmits a control signal at the assigned initial value of the transmission rate. A bit error rate detector detects the bit error rate of the control signal and the initial value of the transmission rate is fine regulated according to the detected bit error rate in order to determine an optimal transmission rate.

Title: Handwear
Inventor: LUGGAR RICKY
IPC: A41D13/08
Filed: 1995-02-13
Abstract: In one form of angling, a fishing line is tied to the tip of a multi-section pole which is often referred to as a "roach pole". No reel is used and in order to place the hook in a desired position the pole is shipped by adding sections of pole to extend the pole until the tip of the pole is suitably placed. To retrieve the line and hook, there is disclosed a glove on which a roller (14, 14a) is mounted for rotation about an axis approximately parallel with the length of a finger when in use. In use, the roach pole can be pushed or drawn smoothly across the roller simplifying the action, so reducing the effort involved, and reducing the skill required to prevent the tip from wobbling.

Patent GB-2309145-A (GB)
Title: Image construction
Inventor: WRIGLEY ADRIAN MARTIN THOMAS
IPC: G06T15/50
Filed: 1995-11-30
Abstract: A ray tracing method for constructing an image of a notional scene from data concerning a plurality of objects (1, 2; 18) in the scene and the illumination of the scene, involves allocating surfaces of objects in the scene into a plurality of subsets, projecting from a notional viewing position (4; 21) a plurality of straight line paths (6; 20) and storing data for all said paths, determining which, if any, of those straight line paths intersect any surface in a selected subset or a zone of illumination, and repeating that step for all the other subsets until all the paths have been tested for intersections (e.g. 12) against all surfaces in the scene. The method also determines, for each path, which intersection is nearest the viewing position and stores data on the co-ordinates for that intersection and on the surface of the object or zone of illumination at that intersection. The intensity on colour of light which will pass along the path through the notional viewing position (4; 21) from that intersection is then calculated and stored, and the stored intensity and/or colour is then used to produce a picture signal for a visual display. A plurality of paths are tested for intersections against a given subset of surfaces before the paths are considered in relation to other subsets, thereby reducing the number of times the subsets have to be called up from the data base. The method can be conducted on apparatus which uses parallel ray processors.

Title: Determining a parameter of a substance, especially a hydrocarbon
Inventor: RANSON AARON
IPC: G01N21/35
Filed: 1997-05-01
Abstract: Determining a parameter of substance, in particular a parameter such as the octane number, oxygen content, aromatic content, etc. of a fluid hydrocarbon, using a measurement cell 10 which defines an inner space 14. The cell has an inlet 16 for introducing a sample of the substance to the inner space, and an outlet 18 for removing the sample. There is also an optic couple in the form of a source 20 and receiver 22 for passing NIR radiation through the sample along an optic path 26 defined by the positioning of the source and receiver. This provides an NIR spectrum which is analysed in order to determine the required parameter of the sample. The cell has a structure, such as contoured elements 24, for directing the flow of the sample in the inner space, so that turbulent flow such as vortices are inhibited and the NIR spectrum can be rapidly provided upon introduction of the sample to the inner space. This arrangement can also be used for separating bubbles and sediment from the sample.

Title: Camera/lens calibration
Inventor: MATHISEN ALLEN E
IPC: G06T13/00
Filed: 1998-03-30
Abstract: A studio camera determines its position by viewing four reference points (eg thumbtacks in a wall) and determining their positions in the camera's field of view; the camera's position is determined by triangulation. To set up the system, the reference points are set up in a rectangle, then the camera is moved around. At each position the camera's position determined in this manner, orientation determined from sensors, zoom and focus condition are recorded in a database. This enables the position to be determined more accurately subsequently. Due allowance for offsets involved in mounting the camera on a support may be made.
