Title: Optical device with two reflective surfaces for inserting in partially open book
Inventor: CHRISTIE-MILLER IAN RUSSELL
IPC: H04N1/10
Filed: 1996-09-25
Abstract: An optical device employs two reflective surfaces 1 and 2 for the recording the contents of a book 3 without opening it more than e.g. thirty degrees. The coupling of two of the optical devices (Fig 4) allows recording of the paper structure and watermarks in a book 3 without opening it more than sixty degrees. The coupled devices may also be used to obtain images of recto and verso plus images of the paper structure and watermarks from either or both sides. Light 6 from a light source emerges at 7 for recording by e.g. a digital camera and computer.

Title: Automobile Headlamp
Inventor: TATSUKAWA MASASHI
IPC: F21Y101/00
Filed: 1996-12-31
Abstract: A bulb 14 is arranged in such a manner that the lower end of a filament 16 of the bulb 14 coincides with an optical axis Ax of a reflector 10. Horizontal cut line forming steps 12aH out of a plurality of light distribution steps 12a constituting a reflecting surface 12 extend over such upper and lower areas as to interpose phantom lines Lh1, Lh2 on the reflecting surface 12 therebetween. The phantom lines will correspond to the horizontal cut lines. Vertical sections of these horizontal cut line forming steps in both upper and lower areas are set to parabolas, each having a short focus, and to parabolas, each having a long focus, respectively. The horizontal cut lines are formed by taking advantage of the luminous fluxes of reflecting light from both areas. Each parabola having a short focus is connected to the corresponding parabola having a long focus at the apex thereof smoothly. As a result, the horizontal cut line forming steps 12aH can be reduced into a single step without steps and bends.

Title: BOP isolation test tool
Inventor: JENNINGS CHARLES E
IPC: E21B34/00
Filed: 1998-01-20
Abstract: A blowout preventer (BOP) test tool (15) comprises an upper tubular member or mandrel (23), a lower tubular member or body (21), a ball valve (25) and a bore (27). The tool (15) is lowered on a string of drill pipe (17) and inserted sealingly into casing hanger (13) positioned within a wellhead housing (11). Body (21) has an enlarged lower portion (22) and a series of seals (24). The tool (15) is inserted into casing hanger (13) with the ball valve (25) in an open position as shown in figure 2. A BOP can be sealingly engaged to the drill pipe above the test tool. Fluid can be pumped down a choke and kill line to test the BOP seal. If required, full closure of the BOP may be tested. Mandrel (23) is picked up and rotated clockwise. This rotation of the upper member relative to the lower member causes the ball valve to rotate to the closed position. The means for actuating the rotation of the valve comprises a drive plate, a clutch and a hub connected to a rocker arm. Once the mandrel (23) has been removed and the valve (25) rotated to the closed position the BOP can be sealed and fluid pumped in via the choke and kill line.

Title: Data carrier deactivation in absence of user data
Inventor: FELDMAN HOWARD RAY
IPC: H04L29/06
Filed: 1998-03-04
Abstract: In a radio communications system in which data is transmitted on a modulated radio frequency carrier, the carrier is switched off when no data is available for transmission. If repeated signalling information is required to be transmitted, only a predetermined number of repeats are transmitted before the carrier is switched off. Data input for transmission is compared with a predetermined bit sequence. If a match is found for any relative bit alignment, this indicates an idle state (absence of user data) and the carrier is switched off. When more user data is received the carrier is switched on and frames are transmitted in synchronisation with the timing of frames transmitted before carrier deactivation. After carrier reactivation a constant power preamble may be transmitted to assist in level control in the transmitter. In a satellite SCPC system satellite power efficiency is improved and mobile earth station battery power is saved.

Title: A mineral separation process
Inventor: MCCULLOCH JOHN
IPC: B04C5/00
Filed: 1998-03-12
Abstract: A process for mineral separation employs a cylindrical separation vessel 1 having an axial inlet 6 for raw material feed, an involute inlet 2 for separating medium which induces vortical flow within the vessel, an axial outlet 4 for low density material and an outlet 8 for high density material. To optimise the process, the pressure of the separation is monitored and is used to control the feed rate of the separation medium into the vessel. The process is particularly useful for the separation of fractions of coal from a process stream of coal containing fractions of differing densities.

Title: Improving the efficiency of a transmitter amplifier by controlling an amplifier voltage using a voltage conditioner such as a switched mode converter
Inventor: LEIZEROVICH GUSTAVO D
IPC: H03F1/02
Filed: 1998-08-25
Abstract: A radio (300) has a transmitter (302) comprising a power amplifier (308), a voltage conditioner (318), and a controller (313). The power amplifier operates at one of a plurality of output power levels. When the output power level is reduced from a maximum setting to a lower setting, the controller adjusts a control signal level provided to the voltage conditioner. The change in control signal level selects a lower output voltage from the voltage conditioner, which is supplied to the power amplifier. By selectively adjusting the voltage level supplied to the power amplifier, the power added efficiency is maintained at an optimum level. The voltage conditioner may be a switched mode converter of buck, boost or buck/boost type.

Title: Triangular mesh decimation method and apparatus
Inventor: SHIN KWANG-SUNG
IPC: G06T17/20
Filed: 1998-12-08
Abstract: A triangular mesh decimation method and apparatus acquires a 3 dimensional image for an object, wherein the 3 dimensional image contains vertices on the surface of the object, each vertex having a depth value representing a distance from a predetermined base plane. The 3 dimensional image is highpass filtered to detect salient vertices and the salient vertices are marked to provide a marked 3 dimensional image, wherein each of the salient vertices has a depth value substantially larger than depth values of its adjacent vertices. A marked triangular mesh corresponding to the marked 3 dimensional image is generated based thereon, with the salient vertices being still marked. Then, non-salient vertices in the marked triangular mesh are decimated, wherein the non-salient vertices are vertices exclusive of the salient vertices.

Title: A cuff pressure controller for the laryngeal masks and tracheal tubes
Inventor: ABDELATTI MOHAMED OSMAN
IPC: A61M16/04
Filed: 1999-04-08
Abstract: A cuff pressure controller for trachea tubes and the laryngeal masks, consists of a modified 10 ml plastic syringe <B>4</B>. The plunger of the syringe was replaced with a metal (screw) bolt <B>3</B>. The bung <B>5</B> of the original plunger was fixed to one end of the metal bolt. A flat washer and gland nut <B>2</B> were screwed over the metal bolt so that the resulting plunger can be rotated forward and backward inside the syringe barrel in a controlled fashion. Rotation of plunger anti-clockwise moves the plunger backward creating a space (external cuff reservoir) in the syringe where excess air from an over-inflated cuff can be vented to control its pressure. Monitoring and control of the pressure may be achieved using a pressure gauge <B>9</B> in line with the cuff and the modified syringe.
