Patent GB-2211315-A (GB)
Title: Laser scanning system
Inventor: MORTON DAVID HUGH
IPC: G02F1/33
Filed: 1987-10-22
Abstract: A laser scanner for a telecine or a telerecorder is proposed in which the laser beams emitted from red, green and blue lasers 11R, 11G, 11B are deflected through individual tracking deflectors 24 to follow individual chirp lenses 28R, 28G, 28B passing through an acousto-optic chirp cell 10. A train of three chirps is launched into the cell and each tracking deflector tracks a different chirp. The frequency characteristics of each chirp are chosen so that the respective laser beam is focused on the film 18 and the intensity control signals applied to the lasers on lines 44 are relatively delayed so as to achieve registration of the red, green and blue scans. Intensity control may be omitted in the case of a telecine machine. <IMAGE>

Title: Spot-the-ball games
Inventor: FENWICK-WILSON ANTHONY
IPC: A63F13/00
Filed: 1989-06-26
Abstract: A method of producing an image for a spot-the-ball competition comprises storing a sequence of images in digital form on computer. The ball is identified on a selected image and an image from the sequence before or after the selected image in which the ball is not at the same location is used to create a new image in which the portion of the image where the ball is located is replaced by a corresponding portion from the other image. The computer stores the coordinates of the missing ball. A grid is then superimposed on the image by generating a pseudo-random number and locating a numbered grid over the image so that the square corresponding to the random number lies over the missing ball. <IMAGE>

Patent GB-2235808-A (GB)
Title: Optically readable data carriers
Inventor: SMALL ERNEST PETER
IPC: G11B7/26
Filed: 1989-08-11
Abstract: Carriers of optically readable data are made as replicas from a master having a storage area onto which data are programmed and separate sets of data are arranged to appear on the data storage area in a plurality of predetermined separate physical locations so that screening of selected locations can be effected to result in only certain data on the carrier being readable. The screening may be accomplished by the application of a printed marking layer on the disc surface, which allows only intended areas of the disc to be read. Windows may be provided in the marked area to allow positional (tracking) information to be read but which otherwise corrupt the data marked off. Alternatively the master disc may be masked so that only the desired section of data are transferred to the copy. <IMAGE>

Title: Attenuated viruses.
Inventor: ALMOND JEFFREY WILLIAM
IPC: C12N7/00
Filed: 1990-01-18

Patent GB-2234613-A (GB)
Title: Method and apparatus for switching contexts in a microprocessor
Inventor: OKIN KENNETH
IPC: G06F9/46
Filed: 1990-03-02
Abstract: An apparatus and method are disclosed for switching the context of state elements of a very fast processor within a clock cycle when a cache miss occurs. To date, processors either stay idle or execute instructions out of order when they encounter cache misses. As the speed of processors become faster, the penalty for a cache miss is heavier. Having multiple copies 8, 10, 11 of state elements on the processor and coupling them to a multiplexer permits the processor to save the context of the current instructions and resume executing new instructions within one clock cycle. The invention is particularly useful for minimizing the average instruction cycle time for a pipelined processor 6 with a main memory access time exceeding 15 processor clock cycles. The number of processes who's states are duplicated may be large. <IMAGE>

Abstract: When using arrangements for transposing containers, such as bottles and the like, which are in the form of sorting or multiple-type apparatus, relatively long bottle feeding means have to be provided on the bottle feed table, which is common to all of the bottles, because of the different types of containers. The invention provides that at least one gripper head (3), which is disposed on a common displaceable cross-piece member, is associated with these bottle feeding means, and each gripper head is adjustable in respect of its gripper height, independently of the vertical position of the other gripper heads, such that, when bottles are picked-up by the other gripper heads, said gripper head cam remain with its tulip-shaped grippers above the plane of the bottle feeding means. Pref. the apparatus is provided with scanning means (25) which prevent the grippers descending if insufficient bottles have arrived to fill a crate (10). The other heads can descend, grip, lift and deposit the bottles in their crates, as normal. <IMAGE>

Title: Marker float.
Inventor: MOORE DOMINIC
IPC: B63B22/08
Filed: 1991-05-24
Abstract: A marker float (1) comprises a spherical buoyant member (2) and a substantially cylindrical chemiluminescent device (3). The first longer portion (4) of a chemiluminescent device (3) extends out of the buoyant member (2) to form indicator means. The other end (5) of the chemiluminescent device (3) is attached to a ledger weight (8) by a length of fishing line (7). The marker float (1) is positioned by wrapping the line (7) around the indicator portion (4) of the chemiluminescent device (3) and holding it in place by overwrapping with soluble line connected both to the ledger weight (8) and a fishing line from a rod. When the marker float is cast into water it sinks under the weight of the ledger weight (8). The soluble line dissolves allowing the marker float (1) to rise through the water whilst shedding the line (7). Once the soluble line has dissolved the casting line may be reeled in. <IMAGE>

Title: Process and arrangement for sinking a deep bore-hole
Inventor: BRUSSMANN DIETMAR
IPC: E21B17/16
Filed: 1991-12-13
Abstract: In a process for sinking a deep bore-hole according to the rotary flushing drilling process, a drill string (2) hanging on a hook and comprising a multiplicity of coupled, hollow drill rods (3) is sunk into the bore-hole. The deepest drill rod carries a rotary drilling tool (5) at its free end. The lower part of the drill string (2) is fitted with at least one heavy element (6), by means of which the cutting pressure of the rotary drilling tool (5) is produced, and the drill string (2) is displaced according to the progress of the drilling by coupling further drill rods (3) on to its upper end. A drilling fluid is fed through the hollow drill rods (3) to the rotary drilling tool (5), where it emerges into the bore-hole. The drilling fluid in the drill string (2) only communicates with the drilling fluid in the bore-hole in the region of the rotary drilling tool (5). The drill string (2) is divided into hydrostatically independent drill string sections by elements (4), which are acted upon at their lower ends and at their upper ends by the hydrostatic pressure of the drilling fluid in the bore-hole. These measures result in the drill string (2) being maintained under tensile stress down to the immediate vicinity of the rotary drilling tool (5). <IMAGE>
