Title: Aliasing reducing filter in image signal manipulation
Inventor: KEATING STEPHEN MARK
IPC: G06T3/40
Filed: 1990-05-30
Abstract: An image signal processing apparatus has an address generator 14 that generates addresses for successive words of a digital input signal representing an input image to be manipulated. Local scaling factor computation means 42 monitors the addresses for successive sets of three words of the input signal, each set comprising first and second words that are relatively horizontally spaced in the input image and a third word that is aligned vertically with the second word in the input image, and computes from each such set both horizontal and vertical local scaling factors representing the extent of compression in the horizontal and vertical directions of a corresponding local area of the manipulated image. A digital filter 40 effects two-dimensional filtering of the input image. Bandwidth control means 44 is responsive to the successive local scaling factors to vary the horizontal and vertical bandwidths of the filter 40 to minimise aliasing that would be caused by the manipulation of the local areas. The computation means 42 computes the local scaling factors for each local area such that the horizontal scaling factor corresponds to the length of a line Ih that extends perpendicularly from a line passing through the positions Ib, Ic of the second and third words in the manipulated image to the position of the first word Ia in the manipulated image and the vertical local scaling factor corresponds to the length of a line Iv that extends perpendicularly from a line passing through the positions Ia, Ib of the first and second words in the manipulated image to the position Ic of the third word in the manipulated image. <IMAGE>

Title: Leaky cable antenna
Inventor: BARTRAM DAVID VAUGHAN
IPC: H01Q13/20
Filed: 1990-06-22
Abstract: A communication system comprises a leaky feeder cable 1 disposed within a housing 8 which provides a discontinuous RF shield. The housing is preferably made of stainless steel, and the discontinuities, which may be apertures 9 are preferably arranged to establish a regular pattern on signals received or transmitted. As an alternative the discontinuities can be provided by a series of separate tubes (Fig 2a). Such a tube may be made with the discontinuities of RF transparent material or may be a continuous RF transparent tube with areas of RF shielding, coating or sheathing. The tube may be notched (Fig 2b). Instead of a circular tube, square or other cross-section tube may be used. Instead of terminating in resistance 2 the ends of the cable 1 can be coupled (Fig 3) to enhance received signals. The leaky feeder may be used for voice, remote control and video communication. The leaky feeder may be used for mobile to mobile communication (Fig 4). A mesh network such as used in buildings is described (Fig 5). <IMAGE>

Title: 'Fuel-free' energy generator
Inventor: STEWARDSON K A
IPC: G21K1/00
Filed: 1990-11-15
Abstract: The energy generator consists of two opposing rigs each comprising a proton producer attached to the commencing end of a length of electromagnetic accelerator tube finishing in a powerful compressing electromagnet. A clutch of protons from the proton producer (the site of which is shown in the diagram at point 1) is accelerated along the tube (point 2) by an array of electromagnets (not shown). As the protons near the end of the accelerator tube they pass beneath a powerful electromagnet (3). The electromagnetic field produced by this electromagnet applies a motive force that impels the protons into close proximity (4). Before the protons can separate they emerge from the end of the tube and collide with another cluster which has emerged from the opposite tube. This kind of collision generates radiant heat - the amount generated being greater than the amount of energy applied - which can be extracted by a heat extraction system. <IMAGE>

Filed: 1991-10-15
Abstract: The alarm bell controller of an electric alarm clock is capable of allowing the alarm clock to sound the alarm either every twelve hours or once every twenty four hours after a specific alarm time has been preset without the need of further adjusting manually the alarm switch to the ON state every day. The alarm bell controller is provided with a first switch 83 and a second switch 84 which are turned on alternatively in a period of twelve hours at the time the hour hand comes into superposition with the alarm hand. A third switch 85, which corresponds to the alarm switch in the alarm clock, is coupled between the first switch and the alarm bell 34. An actuating device 88 is coupled to the third switch and is capable of engaging the third switch when electricity is flowing thereinto. A fourth switch 87 is connected between the second switch 84 and the actuating device 88 and the engagement and disengagement of fourth switch 87 is mutually exclusive to that of the third switch 85. A two-way switch 86 is further provided which can be selected to allow the alarm clock operate either in a MANUAL (12) mode or in a AUTOMATIC (24) mode. <IMAGE>

Filed: 1992-12-03
Abstract: In a butchery process a carcass (1) is cut into primal joints (3,4,5) along one or more cut lines (B-B,C-C). A cut is made skin-deep only, along at least one of the cut lines (B-B,C-C) from the skin side of the carcass.

Title: Pelletising or granulating reactive material
Inventor: HART ALAN DAVID
IPC: B01J2/00
Filed: 1993-03-03
Abstract: The pelletisation or granulation of a material or mixture of materials which is reactive in a liquid to produce a gas is improved by treating the reactive material prior to final compaction to form a coating thereon of a substance which is less soluble in the liquid than the reactive material. The preferred reactive material is calcium hydride and the preferred coating is calcium carbonate with or without calcium hydroxide, formed by treating the calcium hydride with carbon dioxide and water vapour. The pellets so produced have a more uniform hydrogen production rate when used in fuel cells.
