Patent GB-2224129-A (GB)
Title: Optical matrix
Inventor: EDWARDS GEOFFREY STEPHEN
IPC: G02B6/35
Filed: 1988-09-27
Abstract: An optical matrix switch comprising a single crystal silicon slice (8) having a plurality of mutually orthogonal V-grooves (10, 12) etched into its surface using a conventional silicon photolithographic technique, the silicon being crystallographically orientated such that, as a result of the cubic structure of the silicon, the resulting V-grooves are precisely at 90 DEG  to each other, with the sides of each V precisely at 54.74 DEG  to the surface of the silicon. The mutually orthogonal V-grooves (10, 12) serve as guides for a plurality of cylindrical fibre optic terminations (16) so that light signals can be routed from one selected fibre optic (14) to another by the location of a light reflecting means, also formed as an etched silicon crystal with a mirror or pentaprism, at the intersection of the grooves (10, 12) associated with those particular fibre optics. <IMAGE>

Patent GB-2238936-A (GB)
Title: Sound imaging system for video game
Inventor: LOWE DANNY D
IPC: H04S1/00
Filed: 1990-12-07
Abstract: Game software 10 includes sound positioning information that uses speakers 26, 28 to give the player the impression that the sound is emanating from a location other than the actual speaker locations. A sound processor receives monaural signals in response to sound positioning information from software 10 so each monaural signal is divided into two signals, one of which being passed through a transfer function to produce two-channel outputs having differential phase and amplitude adjusted on a frequency dependent basis. Each sound location needs a different relationship using different transfer functions, each embodied by adjusting a digital filter 60 in response to positioning information. <IMAGE>

Patent GB-2252432-A (GB)
Title: Dynamic speed computer bus
Inventor: YEE DAWSON L
IPC: G06F13/42
Filed: 1991-08-30
Abstract: The dynamic speed bus system decreases the length of the bus cycle accesses required for fast peripherals 205; but, maintains normal (longer) length bus cycles for slower peripherals 206. Circuitry is provided to decrease the bus cycle length by increasing the clock frequency to the bus controller 200. When accessing peripherals 206 that can support only normal length bus cycles, the circuitry drives the bus controller with the normal lower clock frequency. When accessing faster peripherals 205, a higher clock frequency is generated such that the waveform transitions smoothly between the low and high bus frequencies. The dynamic speed bus circuitry of the present invention is divided into two logic sections: 1) a decode section 202 and 2) a clock generation section 201. The decode section 202 identifies faster peripherals that are compatible with shorter bus cycles. The decode section signals the clock generation section 201 to supply a higher clock frequency. <IMAGE>
Patent GB-2261030-A (GB)
Title: Recovery of liquids from underground reservoirs
Inventor: HARDIE JAMES FRASER
IPC: F04F1/18
Filed: 1991-11-02
Abstract: A recovery method and apparatus for lifting liquid from an underground reservoir to a well head via a twin nested pipe arrangement extending from the reservoir to the wellhead. The inner pipe (12) conveys the liquid from the reservoir upwardly to the well head and the annular space between the pipes serves to convey a gaseous driving pressure medium e.g. hydrocarbon gas to operate a specially designed jet pump (20, 30) located within the inner pipe. The jet pump receives a supply of the gaseous driving pressure medium from the surrounding outer pipe through an inlet (24), the pressure differential thereby established across the jet pump assisting the uplifting of the liquid through pipe (12) under reservoir pressure and reduces the hydrostatic load of the upwardly moving column of liquid. After carrying out this pumping action, the gas is exhausted into the upwardly flowing column of liquid in the pipe (12) and moves upwardly with it in the manner of a gas lift. Instead of the single tapered nozzle gas outlet (24b), a series of separate jet outlets arranged in a circle may be used. <IMAGE>

Title: Memory utilisation and data retrieval
Inventor: BOLGER MARTIN
IPC: G06F17/30
Filed: 1992-12-21
Abstract: A memory mapping and data retrieval method involves setting up a number of data files 3 which have a header storing values for a number of parameters. An item master file 4 is also set up which has a record for each of the items to which the data relates. Logical addresses are used to determine actual addresses by reference to look-up tables 9, 10, one of which is updated on-line, the other being updated in a batch process. All updates to a data file 3 are recorded in a log file 5 which also includes a log of an access path to the stored data. Because the headers 3a have a number of parameter values, different processors 6 may access the same data file 3 using different logical addresses. <IMAGE>

Title: A hoisting lug
Inventor: NAERLAND ALF SIGURD
IPC: B66C1/66
Filed: 1994-02-24
Abstract: A hoisting lug for use when lifting containers, especially socalled iso-containers (1), formed with socalled iso-corners, each provided with a through-going hole (3) in a top wall, said hole being directed upwardly in the position of use. One has aimed at providing a simple and reliable connection of the hoisting lug (6) to said corner (2) through the through-going hole (3). To this end, the hoisting lug (6) comprises an anchoring member (11) and a separate locking member (12) for the same, said anchoring member (11) having a shaft part (11a) extending outwardly at opposite sides of the shaft part (11a). Thus, the anchoring portion (11c) at the transition to the shaft part (11a) is defined by two border edge portions (11d and 11d'), one at either side of the shaft part (11a), the anchoring portion (11c) at said transition (11d, 11d') having an extent exceeding the largest lateral measure of the hole (3), and the locking member (12) has a shaft part (12a) and a locking portion (12b), the overall width of the locking portion (12b) and the shaft part (11a) of the anchoring member (11), which together constitute the neck portion of the hoisting lug (6), at said transition is only slightly smaller than the extent of the hole (3) in the same direction, so that the locking portion (12b) of the locking member (12) prevents the anchoring portion (11c) from passing into and through the hole (3). <IMAGE>

Abstract: Buoyant articles (e.g. apples 27) are packed by floating the buoyant articles (27) in a liquid, supplying the container (11) to be packed to conveyor means (10), operating the conveyor means (10) to successively pass the container (11) through the liquid and raise the container (11) from the liquid with the container ensnaring at least one buoyant article (27) whilst emerging from the liquid, and separating the container (11) with the buoyant article (27) or articles (27) therein from the conveyor means (10). The containers (11) may be replaced by a continuous film of substrate material which, after emerging from the liquid, is divided into individual substrates each of which carries at least one buoyant article (27), Figure 5 (not shown), or the film substrate may be used on top of a series of containers (11), Figure 4 (not shown). <IMAGE>
Patent GB-2293073-A (GB)
Title: Digital ntsc video signals
Inventor: THOMAS GRAHAM ALEXANDER
IPC: H04N9/78
Filed: 1994-08-31
Abstract: A component of an NTSC colour television signal, e.g. the luminance component, is digitally sampled by sampling an input signal with a mean frequency related to the colour subcarrier frequency, e.g. 2fsc, and changing the sampling phase between successive lines of a field by an amount equal to half the interval between samples. The sampling pattern repeats every four fields, and the sampling phase changes by 180 DEG  between corresponding points on adjacent pictures. The phase shift between fields 1 and 2 of the four-field structure can be +90 DEG  and the phase shift between fields 3 and 4 can be -90 DEG , or vice versa. This can be used in a coding method which involves sub-band analysis filtering the luminance input video signal into a low-frequency luminance signal and a high-frequency luminance signal, sub-band synthesis filtering the high-frequency luminance signal and the chrominance input video signal to form a combined high-frequency signal, and phase-segregated coding the low-frequency luminance signal and the combined high-frequency signal to provide the composite video output signal. <IMAGE>
