Patent GB-2274023-A (GB)
Title: Radar reflectors
Inventor: RIX CLIFFORD
IPC: G01S13/02
Filed: 1994-02-14
Abstract: A radar reflector comprises a pair of opposed colinear solid dielectric lens reflectors (10) and two corner reflectors (11) between to provide substantially uniform and high reflectivity in the plane of the reflector elements. Radar energy strikes the outer convex surface of a first converging lens element (12) of relatively high dielectric constant and is then transmitted through a second lens element (17) of material having a relatively lower dielectric constant to a reflecting metallic coating (18) on the outer convex surface of the second lens element (17). The surfaces of the two lens elements (13, 14, 18) are formed such that their respective radii of curvature decrease with distance from the axis of symmetry (15). The first lens (12) is preferably silica flour in a polyester resin with a dielectric constant substantially equal to 3.4 while the second lens element (17) is an expanded foam polystyrene with a dielectric constant substantially equal to 2. Preferably the corner reflectors (11) are trihedral reflectors. <IMAGE>

Title: Pheumatic conveying system for rod-like articles
Inventor: SEIM II ALBERT DANIEL
IPC: A24C5/47
Filed: 1994-02-18
Abstract: In a pneumatic filter rod conveying system between a distributor (2) and a receiver unit, a vent (12) is provided in an interconnecting conveyor (10), close to the distributor (2). This enables a relatively high pressure gradient to be established, with resultant high filter transfer rates at the distributor, without having excessively high pressures in the distributor and/or higher than necessary line transmission speeds. Also provided is a selectable pressure switch (40) for reducing air pressure at the distributor when there are fewer than normal filters in the line, e.g. at the end of a run: this also allows avoidance of undesirably high line transmission speeds. <IMAGE>

Title: A microcell asynchronous demultiplexing and multiplexing device
Inventor: MOURIER MARC
IPC: H04L12/70
Filed: 1995-12-27
Abstract: Transmission in asynchronous mode for multiservice networks with a wide bit rate range means that digital data is transported in standardised ATM cells featuring a header and a payload of fixed length. For low bit rate services penalised as far as transmission efficiency is concerned on network routes, the process, whilst effecting all switching and all transmissions on cells in standardised format, multiplexes and demultiplexes microcells from different communications thus avoiding the transmission of partially filled standardised cells, and permitting standardised ATM networks to be transited without these networks recognising these microcells. The cells from various sources may comprise completely filled cells C 0 which are transmitted unchanged, cells with a single microcell C 1 or cells with more than one microcell C 2 . The last named are demultiplexed to single microcell packets according to defined rules 3 and as far possible reassembled into full packets for transmission. This process restricts the amount of empty packet structure, thus optimising transmission capacity.

Title: Superimposed variations on back emf sensing angular position
Inventor: STOCKSCHLAGER ALFONS
IPC: H02K7/04
Filed: 1996-09-06
Abstract: Windings 24A, 24B ... produce a varying back emf as the rotor rotates causing a corresponding variation in motor current at a frequency dependent on the number of windings. One of the windings is wound with for example fewer turns so as to superimpose a cyclic variation on the back emf related to angular rotor position. This is detected and used to count the number of revolutions of the motor in a vehicle window winding arrangement so as to determine the fully closed/open positions. Alternatively, a resistor may be connected across the windings or the winding spacing may be varied.
