Title: Pocket belt conveyor
Inventor: NOLTE GUNTHER
IPC: B65G17/04
Filed: 1993-07-16
Abstract: Several spaced cross bars (12) are set between two traction supports and the pockets (13) are fixed between the adjoining cross bars. The pockets have a rubber or rubber-like base wall and in order to fix this the cross bars have a fastening surface which is inclined to the traction supports. The cross bars are preferably of triangular cross-section such as a right-angled isosceles triangle. The cross-sectional shapes can be different in the longitudinal direction so that a reduced cross-sectional surface is formed between the traction supports. The cross bars are made of rubber or rubber-like material reinforced by a single steel cable or tube in the centre. Advantage - More reliable filling of the pockets without loss of material. Reduced wear by avoiding relative movement between parts.

Patent ZA-936591-B (ZA)
Title: System for termite detection and control
Inventor: THORNE BARBARA L
IPC: A01M1/00
Filed: 1993-09-07
Abstract: A system for termite detection and control is provided by a subterranean bait station having a perforated outer housing permanently implanted in the terrain below ground level, and a perforated cartridge removably received within the housing. The openings in the housing and the cartridge are in alignment with each other when the cartridge is fully received within the housing in its operational position. The cartridge received within the housing will initially contain a non-toxic bait material for diagnosing or assessing the level of a termite infestation; the bait cartridge is periodically removed from the housing to inspect for termite activity. If termite activity is detected, the non-toxic bait cartridge is replaced in the housing with a correspondingly perforated pesticide-containing bait cartridge for extermination of termites. Removal, replacement and substitution of the non-toxic and pesticide containing cartridges does not disturb pre-existing termite foraging galleries as a result of the precise alignment of the openings of the housing and the removable, exchangeable cartridges. The system may also be used for above-ground termite detection and control by externally mounting an appropriately modified housing to an outer surface of any article to be monitored, such as a timber.

Title: A system for the correction of missing or deleted symbols
Inventor: TOMLINSON MARTIN
IPC: G06F11/08
Filed: 2004-12-22
Granted: 2008-10-08
Abstract: In many communications systems, broadcasting systems and storage systems, information is encoded as a sequence of symbols. The total number of symbols transmitted or stored is denoted by n, and these are obtained by encoding k information symbols using parity check equations from an error correcting code (ECC). The present invention allows the k information symbols to be recovered before all n symbols have been received or read, thereby compensating for missing symbols and allowing faster access to the information. Three decoding methods using parity check equations to recover missing symbols are described, each of a different degree of complexity. It is shown that the present invention can cope with a higher number of missing symbols than the current state of the art.

Abstract: PCT No. PCT/DE79/00090 Sec. 371 Date Apr. 21, 1980 Sec. 102(e) Date Apr. 21, 1980 PCT Filed Aug. 18, 1979 PCT Pub. No. WO80/00423 PCT Pub. Date Mar. 20, 1980. A pulp suspension of waste paper which is laden with air bubbles is introduced into a flotation cell. Fine air bubbles rise through the pulp suspension toward the top. Printing ink and other impurities are deposited on the bubbles which form a foam layer on the surface of the pulp suspension. The foam which is laden with impurities is drawn off from the surface. The fibers which have been subjected to preliminary purification in this manner sink downwardly. For reducing the number of cells connected in series to fewer than a third, while obtaining the same degree of whiteness, the fibers which were subjected to preliminary purification are drawn off and are once again supplied to the flotation cell in the form of an air-laden pulp suspension. Alternatively, instead of the air-laden pulp suspension, a water-air suspension can be injected. The air bubbles which are thus introduced once again rise toward the top and traverse the sinking fibers in a counterflow. As a result, an intensive air-pulp contact is created.

Title: Sealing device made of metal for a highvacuum closure
IPC: F16K1/34
Filed: 1980-11-24
Granted: 1983-12-14
Abstract: A sealing device for a high-vacuum closure, such as used in a high-vacuum valve, where the surfaces effecting the seal are formed of metal. In forming the seal, a sealing member extends between and into contact with a pair of laterally spaced sealing surfaces. The surfaces on the sealing member which contact the sealing surfaces are rounded and have a radius of curvature equal to half the dimension of the sealing member between the sealing surfaces when it first contacts the surfaces during the closing step. The sealing surfaces can be frustoconical or spherical. When the device is closed, sealing force presses the sealing member between the sealing surfaces so that a relative rolling action takes place. Only elastic deformation occurs when the seal is effected.

Abstract: In a decoupling arrangement for an integrated circuit device incorporating a lead frame of the sort which includes an elongate metallic web the lead frame provides an integral seat or platform (23, 24) whereon is mounted a decoupling capacitor (C) which is connected in shunting relation of the power supply inputs to the integrated circuit device, the capacitor (C) providing a convenient mounting platform for the integrated circuit chip 12 and also assuring minimal lead lengths between the capacitor and the power supply inputs of the integrated circuit chip. Due to the shortness of such lead lengths and consequent reduction of the inductance reactance of the power supply circuit, efficient dampening of switching transients is achieved with the use of capacitors of much smaller values, in less area than heretofore required in external dampening applications. <IMAGE>
