Title: Image-data reduction technique
Inventor: ANDERSON CHARLES HAMMOND
IPC: G06T9/00
Filed: 1986-07-22
Abstract: First processing means 202 converts a high-resolution, wide field of view image signal into a series of output signals, ranging in resolution from high resolution, L0, to low resolution, GN, representing the same field of view. These signals, except for GN, are further processed by second processing means 204-0 to 204-(N-1) to produce final output signals ranging in field of view from a low resolution image of the entire field of view, GN, to a highest resolution image of a selectably positionable smallest spatial sub-region of the entire field of view, L'0 (see Figure 5). The arrangement is such that each of the final output signals L'0-LN-1, GN comprises the same number of pixels. This eases subsequent computing requirements. The technique finds a use in foveated electronic cameras which may be used in surveillance or robotic systems. <IMAGE>

Patent GB-2215136-A (GB)
Title: Broadsword anti-radar foil
Inventor: HUTCHINS RONALD CECIL
IPC: H01Q15/14
Filed: 1988-02-10
Abstract: The limited advantage of chaff when the radar detection system to be confused has moving target indication (MTI) to screen out such 'slow moving' targets, is countered by the use of offset 45 degree angle fins at the base of the chaff foil pieces so as to present a doppler complication to the reflected radar wave. The rotational velocity of the foil could show up just as readily as a linear velocity of a target such as an aircraft. With many of this type of foil aloft, and each having somewhat different rotational velocities, the doppler system can conceivably be confused. At the same time, the rotation of these units help to increase the target area making a cluster of such units seem larger than actual in terms of the radar signature. The design geometry of the blade coupled with the angular displacement of the fins, serve to govern the rotational velocity of the unit in flight, thus presenting each reflecting surface for a slightly longer exposure than if the blade were pointed and the edges streamlined. Prototypes have proved the aerodynamic stability of the units, and the added advantage of compacted stowage in a limited space is readily observed. <IMAGE>

Patent GB-2215153-A (GB)
Title: Low level D.C. amplifier
Inventor: MOOREY ERNEST JAMES
IPC: H03F3/38
Filed: 1988-02-24
Abstract: A D.C. amplifier comprising a number of modulators, in this case 2 (ABCD) and (EFGH), followed by A.C. amplifiers, A1 and A2, demodulators, (JKLM) and (NPQR), and D.C. amplifiers A3 and A4. The modulators are so driven that, while one channel is changing phase, the other channel(s) are not changing phase. A signal at the input is sequentially inverted by the modulators, which are time displaced from one another. In the case of a two channel system, the modulators and demodulators would normally be displaced from each other by a phase angle of 90 degrees. Following synchronous demodulation, the signals are added together and further amplified by D.C. amplifiers. <IMAGE>

Patent GB-2332735-A (GB)
Title: Dispersion container for ammunition
Inventor: HUTTER HORST
IPC: F42B12/58
Filed: 1988-04-11
Abstract: A dispersion container 10 in which the muzzle velocity of the ammunition 12 can be altered in accordance with the target by time-based adaptation of the action of opening a pressure chamber 24 positioned between the gas generator 11 and the ammunition tube 10 during the ejection of the ammunition. In separation, gas from the generator forces securing element 30 against the action of spring 31 to align channels 32 and 23. An impulse can then be transmitted from target data computer 27 to ignite primer 25; gases therefrom pass into chamber 24. The build-up of pressure shears pin 21 to eject plug 20 from the container 10 and cause a drop in pressure. If the primer is ignited whilst the element 30 still blocks channel 23, gases can escape through borings in plate 34.

Title: Electronic equipment cabinet
Inventor: REYNARD DEREK THOMAS DUNCAN
IPC: H05K9/00
Filed: 1989-02-22
Abstract: An electronic equipment cabinet having a hinged door 3 located in a door frame 2, in which a door edge which is located on an opposite door side to the hinge carries a hinged door flap 4, such that the flap 4 and the door 3 may be folded out of a common plane when the door is in an open condition, the flap 4 and the door 3 being movable into their common plane upon closing the door within said frame 2, the action of closing said door serving to expand the door and flap combination sideways such that a sealing gasket 7 at the door/flap edge will be compressed as the flap and door are moved to the closed position. This allows effective sealing of the door in order to reduce the possibility of any internal or external electromagnetic affecting apparatus outside or inside the cabinet. When the equipment housed is a digital telephone exchange, for example, the use of the cabinet will then ensure electromagnetic compatibility with other equipment. <IMAGE>

Title: Method of manufacture of crusted pie casing
Inventor: KORCZYNSKI ANDRZEJ NICHOLAS
IPC: A21B3/13
Filed: 1989-08-03
Abstract: A flat piece of pastry or dough or similar material, 11, is placed on the outside of an upside-down mould, for example a baking tin, 10. The pastry or dough is of a larger size than the mould (e.g. of a larger diameter) so that it fits over the mould. With the tin still upside-down, the pastry or dough material is baked in a normal manner on the mould. A weight, for example a wire tray 12, may be placed on top of the pastry or dough during baking to prevent the crust separating from the rest of the pastry or dough and forming an air bubble. A pastry or bread shell is produced with a crust on the outside and softer material on the inside. This can be filled as desired and is easily eaten by hand. <IMAGE>

Title: Method for preparing pasta-containing retort food and preparation of pasta
Inventor: YAMAMOTO MASANORI
IPC: A23L7/109
Filed: 1990-07-02
Abstract: A method for preparing a pasta-containing retort food comprises introducing dried or partially dried (as described) pasta and water-containing sauce for seasoning into a heat resistant container, sealing the container and adjusting the water content of the pasta to 50 to 85% or 60 to 85% by weight by subjecting the pasta-containing food packed in the container to a retort-sterilization treatment. A method for preparing pasta comprises forming pasta dough from 45 to 83% by weight of flour, 0.3 to 4% by weight of thermally coagulable protein, 0.1 to 2% by weight of gums and/or 5 to 20% by weight of a starch and 13 to 25% by weight of water, then drying the resulting pasta dough at a temperature from 75 to 95 DEG C and relative humidity from 30 to 90%. These methods make it possible to prevent pasta from becoming soggy during a retort-sterilization treatment and to provide retort foods which contain pasta having excellent texture and taste when they are heated and cooked in the home with an oven toaster or the like.
