Abstract: PCT No. PCT/FI94/00302 Sec. 371 Date Jan. 5, 1996 Sec. 102(e) Date Jan. 5, 1996 PCT Filed Jun. 30, 1994 PCT Pub. No. WO95/02307 PCT Pub. Date Jan. 19, 1995In a digital time division multiple access (TDMA) radio system, the transmission times of mobile stations in a cell are advanced in relation to the base station of the cell each by a timing advance which compensates for the transmission delay caused by the distance between the base station and the respective mobile station. Part of the radio capacity of the cell is arranged to serve only within a first given timing advance range, and thereby to serve mobile stations located within a first given area of the cell, and another part of the radio capacity is arranged to serve only within a second given timing advance range, which is different from the first timing advance range, and thereby to serve mobile stations located with a second given area of the cell. The first and second areas may partially overlap. Handoffs between channels of the capacity are accomplished on the basis of exceeding or falling below threshold timing advance values.

Title: Coated media for chromatography
Inventor: VARADY LASZLO
IPC: B01J20/281
Filed: 1991-01-16
Granted: 1992-09-17
Abstract: Disclosed are pellicular materials useful in contact with proteins and as chromatography media. Rigid, inert, hydrophobic, polymeric materials are exposed to a solution comprising a solute defining plural interspersed hydrophobic and hydrophilic domains. The solute molecules adsorb onto the surface of the substrate by hydrophobic - hydrophobic interaction with their hydrophilic domains extending outwardly away from the surface into the solution. The molecules are then crosslinked in place to produce a solvent and pH resistant coating which presents a hydrophilic surface sufficient to mask hydrophobic regions therebeneath. The multidomain adsorbing compounds may comprise reactive groups which subsequently can be derivatized using conventional techniques to produce chromatography materials useful for conducting affinity, size exclusion, cationic exchange, anionic exchange, neutral hydrophobic interaction, and other forms of chromatographic separations.

Title: Improvements in collation assemblies
Inventor: OBEROI BHUSHAN KUMAR
IPC: B65G57/14
Filed: 1987-11-17
Granted: 1990-06-21
Abstract: The invention relates to apparatus for collating and stacking building components, such as roof tiles. The apparatus comprises pairs of shelves (24) for receiving and supporting tiles which are fed into the shelves continuously by means of a conveyor arrangement. The shelves are moved downwards towards a stack support positioned beneath the shelves. As a pair of shelves becomes the lowermost pair, the two shelves move apart releasing the tile carried thereon onto the stack support to form part of a stack. When the stack is complete, the stack support is removed and the number of shelves between the uppermost and lowermost shelf increased to enable a predetermined number of tiles to be stored in the shelves whilst the stack support is being replaced.

Title: Automatic train marshalling logic control circuit - makes provision for high or low entry speed of shunted sections (OE150575)
IPC: B61B1/00
Filed: 1971-07-22
Abstract: The forwarding section of track is equipped with a rail brake and a track occupation indicator. The exit of vehicles is detected by a contactor. The speed of a shunted train section as it leaves the brake is measured by radar equipment. The target speed is represented by an adjustable analogue voltage applied as a reference to a comparator circuit. The comparator produces an output signal when the presence of a train section is indicated and is lower than target. A network of logic circuits, switched by the occupation indicator, the comparator and the exit contactor controls the movement of the propelling trolley, whose arm engages with the leading axle of the train section and feeds it forward at an appropriate speed.

Title: Large ventilating duct flanged connection - uses curved spring strip clip to clamp hollow angle shaped flanges together
IPC: F16L23/14
Filed: 1971-08-04
Abstract: A prefabricated coupling for large rectangular air ducts includes two hollow angle flanges (11, 26). On installation, the duct walls are pushed into the axial slots which are formed by the hollow angles. The upright parts (13) of the angles are placed back to back to produce the coupling plane at right angles to the duct axis. A C-shaped spring steel rail (31) is then driven by hammer blows over the mushroom shaped outer edge (27) which is formed by the two angles. The clamping force so obtained firmly locates the duct walls in the correct relative position.

Abstract: An electronic watch is set to the proper time by correction of the content of counters of the watch through the actuation of one or both of two switches. The actuation of the first one of the switches selects whether the content of the counters is to be incremented or decremented at a first speed. The subsequent actuation of the other switch performs the correction at a second higher speed in the sense selected by actuation of the first switch.
