Title: Video processing systems
Inventor: TAYLOR RICHARD JOHN
IPC: G06T3/40
Filed: 1983-03-11
Abstract: An input video frame comprises low definition pixels (K, L, M, N frame 1 and Q, R, S,T frame 2) at a low frame rate. The input frame is stored in a high definition frame store which is recursively updated and filled using spatial interpolation (Fig. 8). e.g. to give a value at W, and temporal interpolation (Fig. 9) to give values between the input frames and enable an output at a higher definition and higher frame rate. <IMAGE>

Title: Method and apparatus for starting an electric starting motor adapted for starting an internal combustion engine
Inventor: HAMANO ISAO
IPC: F02N11/00
Filed: 1983-05-19
Abstract: An electric starter motor for an internal combustion engine has a pinion at its shaft end for meshing with a ring gear of the engine. The pinion is shifted by a shift lever into a position meshing with the ring gear, after which the starter motor is excited to turn the ring gear and thereby start the engine. Initially, until the pinion engages the ring gear, brushes 8 of the starter motor are shifted away from the electrically neutral axis towards pole sides of trio stator permanent magnet of the motor whereby the main magnetic field produced by the magnet is strengthened by the armature- reaction magnetic fluxes. After the pinion is engaged with the ring gear said brushes are returned to their positions on said neutral axis. The brushes 8 are on brush holders 10 which are moved by a small D.C. motor 15 controlled by a control unit 17 when the ignition switch 18 is operated, the motor 15 driving a pinion 152 engaged with a partial ring gear 102 formed in the brush holders 10. <IMAGE>

Title: Data storage medium
Inventor: PETTIGREW ROBERT MARTIN
IPC: G11B7/24073
Filed: 1983-11-21
Abstract: A data storage medium is provided which is suitable for production or replication by moulding, casting, embossing or a similar process against a tool. The data storage medium has a surface or a surface region which is strongly absorbent of at least a predetermined band of wavelengths of electromagnetic radiation. The surface or surface region includes a layer of a heat sensitive material which has a textured surface pattern the pitch of which is smaller than the shortest wavelength of the predetermined band of wavelengths, and the depth (peak-to-trough) of which is at least 100 nm. The surface pattern is free from undercutting, and can comprise an array of protuberances or one or more sets of grooves (which may be intersecting). The textured surface is of high opacity at least at, and just below, the surface which in use is to be exposed to writing radiation. A filled plastics material, e.g. PVC filled with carbon black, may be used. A tool for use in producing such a data storage medium, and methods of using the tool, are also disclosed. The data storage medium may be prepared in blank form for use as the consumer desires, or it may be pre-recorded in part or in entirety.

Title: Optical inspection system
Inventor: FULKERSON EMMET MITCHELL
IPC: G01S17/32
Filed: 1984-02-09
Abstract: An optical inspection system utilizes triangulation principles wherein an indexing light beam 6 is projected to a lens 18, parallel to the optical axis 21 of the lens, and focused by the lens to one focal point 24 of the lens. An object 33 present near the focal point reflects light, some of which 36A, 36B is captured and collimated by the lens. A photodetector 57A, 57B detects the collimation and produces a signal when a particular type of collimation occurs, indicating that reflection occurs exactly at the focal point. Thus, the position of the object is ascertained. Provision 12A, 12B is made for scanning the indexing light beam along a focal plane 30 for contour scanning of the object located near the focal plane. <IMAGE>

Title: Smoke detector
Inventor: BARRETT ROGER
IPC: G01N27/66
Filed: 1984-04-10
Abstract: A smoke detector includes two ionisation chambers, 1 and 2, in cascade, chamber 2 being used as a reference chamber. Connected to junction 3 of the chambers, 1 and 2, is a high impedance switch 4. The potential at junction 3 is monitored by the switch 4, which conducts above a predetermined threshold value indicating that a certain amount of smoke has been detected. Capacitor 6 is then caused to charge via a path consisting of diode 5, conducting switch 4 and resistor 7. When the voltage across capacitor 6 exceeds a set value, transistors 9 and 10 are switched on and thereafter form a latch which maintains a set voltage across detector terminal lines, 12 and 13, regardless of any subsequent variation in the potential at junction 3. The latch triggers off an alarm, (not shown) such as a bell or a light, to indicate that smoke has been detected. <IMAGE>

Title: Dense medium separator
Inventor: DOUGHTY JOHN PAUL CARROLL
IPC: B03B5/34
Filed: 1985-04-23
Abstract: A dense medium separator has a vessel (1) with a generally cylindrical upper portion (2) and a generally conical lower portion (3), an axial feed aperture (4) at the upper end and a lower axial float discharge aperture (6) at the lower end, a first sinks orifice (8) disposed generally tangentially at the upper end, a lower sinks orifice (9) disposed generally tangentially at the lower end and an inlet aperture (10) for medium disposed tangentially intermediate between the ends of the vessel. In operation, the medium, fed tangentially at (10), divides so that a proportion (11) flows towards the first sinks discharge orifice (8) and the balance (12) flows towards the second sinks orifice (9) with the volume of medium which is discharged at each sinks orifice being controlled by the orifice area and back pressure applied to the flow. The balance of the medium flow towards the first sinks orifice (8) which is not allowed to leave the vessel via this orifice reverses direction close to the feed entry pipe and flows axially (13) towards the float discharge aperture (6) in the lower end wall. At the second sinks orifice (9) a proportion of the medium close to the wall is discharged through this orifice and the balance is discharged through the float aperture (6). <IMAGE>

Title: Improvements in or relating to devices for continually releasing liquid
Inventor: DRANSFIELD MARTIN
IPC: C02F3/04
Filed: 1985-04-29
Abstract: A device for the continual release of batches of liquid from a reservoir which is itself continuously filled at a slow rate, and particularly for the periodical release of liquid effluent from the rotary arm assembly of a sewage trickle filter bed. The device comprises a "U"-tube 21 with one limb taller than the other. The free ends of the taller and shorter limbs are respectively connected to the reservoir outlet and open to atmosphere, so that atmospheric pressure can support a head of liquid within the tube when the latter is full and the reservoir outlet is closed by a seal 25. That seal 25 is buoyant, located within the reservoir and restrained from lateral movement so that it tends always to approach and close the outlet as the reservoir level falls. <IMAGE>

Title: Growing strawberry plants for fruiting out of season
Inventor: DODD PETER BRIAN
IPC: A01G7/00
Filed: 1986-01-14
Abstract: Leafed plantlets are first grown to develop roots using bottom heat, the roots being maintained at a temperature of at least ambient temperature (eg 15-20 DEG C), the plantlets are then treated to promote the production of crowns, eg by removing the apical bud or by root treatment with 2-chloroethyl trimethyl ammonium chloride (chlormequat), and growth is then allowed to continue (still using bottom heat) until 4-5 crowns per plant are produced. The plants are then cultivated for fruiting or are first cold stored. The initial plantlets may be propagated by a similar process in which the promotion of the production of crowns is replaced by the promotion of the production of runners, eg by root treatment with giberellic acid.
