Abstract: An isolation member (34) for use in a non-electric detonator cap (10) is of substantially cylindrical shape and has an interior passageway (40) extending therethrough and defining a positioning region (44) and a discharge port (56). Positioning region (44) is dimensioned and configured to snugly receive and seat therein a signal transmission line (30) and to orient the signal-emitting end (30a) thereof to aim along the longitudinal axis of cap (10) through a diaphragm (42) at the target provided by receptor charge (14). The isolation member is positioned between, and spaces the signal-emitting end (30a) of the signal transmission line (30) from the receptor charge (14) contained in the detonator cap. The isolation member comprises grooves (58, 58a, 58b) to provide an alternate flow path through which a signal emitted by the discharge end (30a) of a signal transmission line (30) can reach the receptor charge (14) should the signal fail to burst the diaphragm (42). The isolation member is preferably made of a semi-conductive material to bleed off to the shell (12) any static electricity charges transmitted through the signal transmission line (shock tube 30) so as to prevent static discharge initiation of the charge.

Abstract: A sprayer attachment is designed for mounting upon a swather tractor and includes a central frame with a tank which can be carried upon the front arms of the swather tractor. Two masts each carry a respective one of a pair of booms, each for extending outwardly to a respective side of the tractor for movement with the tractor in a spraying action. Each boom includes an inner section, an outer section and a tip portion. In the folding action the outer section and tip portion are folded about a horizontal axis so as to move to a position overlying the inner section. The folded boom is then pivoted about a vertical axis at the mast to lie along side the side of the tractor. The tip portion includes a parallel cable in advance of the tip portion for impacting an obstacle with the cable actuating release of the latch and accelerating the tip portion away from the obstacle to prevent impact with the obstacle. The tip portion is also moved to the retracted position during the folding action so that the maximum height of the outer section during folding is reduced to avoid contact with power lines and the like. The booms are inclined outwardly and rearwardly in the extended position to move the center of gravity rearwardly.  The tank has two recessed sides to receive the arms of the swather tractor and a front which is inclined forwardly and downwardly to improve vision. Each boom is movable vertically along a vertical supporting mast independently for height adjustment. A hydraulic and electrical coupling allows the existing control lever of the swather tractor to control the boom movement.

Title: Radio communications systems and methods for jittered beacon transmission
Inventor: HAARTSEN JACOBUS CORNELIS
IPC: H04B7/26
Filed: 1997-08-22
Granted: 2003-04-22
Abstract: Radio beacon transmission between a private radio communications base station and a mobile terminal within the transmission range of the private radio communications base station designed to prevent interference with overlapping uncoordinated private radio communications networks is provided by jittered beacon transmission. The private base station transmits radio beacon bursts at jittered time intervals, which vary pseudo-randomly to prevent repeated radio beacon collisions between uncoordinated private radio communications networks with overlapping transmission ranges. The beacon time jittering is performed pseudo-randomly in a pattern which is associated with a base station identification value. The mobile terminal derives the base station associated identification value and status information from a received radio beacon and determines if the base station is available for communications with the mobile terminal. The mobile terminal further synchronizes with the jittered base station beacon transmissions based on the pre-determined jitter generation function associated with the base station identification value derived from the received radio beacon. The mobile terminal is thereby able to readily maintain synchronization with one or more private radio communications network base stations without losing synchronization due to repeated radio beacon burst collisions between the base stations.

Title: Device for filtering fluids containing impurities
Inventor: BACHER HELMUT
IPC: B29C48/03
Filed: 1997-12-03
Granted: 2004-07-20
Abstract: The invention relates to a device for filtering fluids, notably plastified, thermoplastic materials, containing impurities, particularly in the form of solids. Said device comprises a case (1) containing at least one fixed, substantially level filter (5). The fluid to be filtered is fed to the filter (5) in the area around its periphery by means of at least one inlet channel (3). The filtered fluid is led out of the case (1) via at least one outlet channel (7). At least one scraping element (17) is pressed with its scraping edge (31) against the inlet-facing surface (11) of the filter (5), and is movably fixed to a support (12) which can be rotated by a drive element (15) around an axis (14) substantially perpendicular to the inlet-facing surface (11) of the filter (5). The scraping element (17) scrapes off the impurities adhering to this surface (11) and moves them to the centre of the filter (5). from where then are evacuated by means of at least one endless screw (38) via at least one evacuation channel (39) starting at the centre of the filter (5) and leading out of the case (1). At least one scraping element (17) is fixed on a support (12) in such a way that it pivots around an axis (18) and sticks out from said axis in the direction of the rotation of the support (12) and at an oblique angle to the filter (5). The scraper edge (31) of the scraping element (17) is pressed against the filter (5) when the support (12) rotates as a result of the counter-pressure generated by the fluid to be filtered. This effectively prevents blockages of the scraping elements (17).
