Title: Portable cordless telephone systems
Inventor: BARNES NIGEL EVERARD
IPC: H04B7/26
Filed: 1990-02-28
Abstract: The telecommunications system comprises a plurality of distributed base stations (BS1..BSn) each operatively coupled to a public switched telecommunications network (PSTN) and being adapted to co-operate with one or more of a plurality of portable cordless telephone units (CT1..CT4) by way of a plurality of cordless digital communication channels operating on a time division duplex basis. The base unit (BS1..BSn) is arranged upon detection of an incoming public switched network call, to poll all the portable cordless telephone units (CT1..CT4) by transmitting on a repetitious basis the identity of the portable units to be connected to the incoming call on a selected channel and the base unit (BS1..BSN) is arranged to intersperse each poll operation with a signalling message. Each portable unit (CT1..CT4) is arranged to scan the cordless channels at a predetermined interval and the base unit (BS1..BSn) is adapted to postpone the sending of a ringing message to any of the portable units (CT1..CT4) until a predetermined period has elapsed since the commencement of the polling action, the predetermined period being substantially similar to but larger than the predetermined interval.

Title: Paper-shearing device
Inventor: LO KUN-NAN
IPC: B26D7/26
Filed: 1990-10-12
Abstract: A paper shearing device includes a power operated active blade (20) having an inclined blade edge (21) and a passive blade (30) having a second blade edge (34). A bolt (40) fastens the passive blade (30) to a stationary positioning plate (13) in a limitedly movable position with a resilient piece (50) located between the stationary positioning plate (13) and the passive blade (30) which provides easy relative adjustment of the blades. The resilient piece (50) urges the passive blade (30) to a position that permits the inclined blade edge (21) to contact the second blade edge (34) when the blade (20) is moved towards the passive blade (30) to effect shearing. Further movement of the blade (20) pushes the passive blade (30) against the action of the resilient piece (50), as a web of paper (11), particularly in a fax machine, is sheared. <IMAGE>

Title: Aspect ratio measurement of non-spherical particles
Inventor: GATE LEONARD FARLAM
IPC: G01N15/00
Filed: 1991-01-21
Abstract: A method and apparatus are disclosed for obtaining a measurement indicative of the aspect ratio of non-spherical particles in suspension (1). Conductivity of the suspension is measured (9, 10) for two different orientations of the particles between points (5 and 6) and the difference between the conductivities measured is used as an indication of the particle aspect ratio. The particle orientation will be aligned in one measurement and in the other may be aligned and transverse to the first orientation direction or random. Alternatively there may be a single aligned orientation but transversely directed conductivity measurements. A flow shear, electric, magnetic or acoustic shear field may be used to orient the particles. <IMAGE>

Title: Arrangement for actuating a motor vehicle friction clutch disconnects engine accelerator control until after gearshift
Inventor: KONRAD ANDREAS
IPC: B60W10/10
Filed: 1991-04-18
Abstract: For the automatic actuation of a friction clutch (5) arranged between an engine (1) and a gearbox (7) of a motor vehicle there is proposed a control means (19) which reduces the power of the engine (1) during the gear change of the gearbox (7) while the gearbox is shifted via the neutral gear position thereof. During re-clutching after the gear change, the engine speed is automatically adapted to the gearbox input speed in order to avoid a clutching jolt. "Double-declutching" is carried out when shifting down the gearbox (7) to minimise the load on controlled synchroniser mechanisms of the gearbox (7). <IMAGE>

Title: Apparatus and method for cutting wires of equal length
Inventor: DE LA FUENTE CARLOS
IPC: E01D19/16
Filed: 1992-06-30
Abstract: Wires (4) of identical length are produced, by unwinding from a coil (6), a first "reference" strand extending obliquely between a high point A and a low point B close to the coil, and the relative level H0, with respect to the level of the point B, of a point M, of the said strand, located at a given horizontal distance from the point B, is measured. The end of the said strand is cut at a fused point C. Successive strands are then stretched between the two points A and B until the relative level of the point M corresponding to each of these strands is equal to the value H0 of the point M of the reference strand; and these successive strands are cut in turn at the point C when the abovementioned equality is realized. The strands are wound together to form cables of suspension bridges. <IMAGE>

Title: Seat belt retractor
Inventor: FUJIMURA YOSHIICHI
IPC: B60R22/42
Filed: 1993-04-06
Abstract: In an emergency, a pawl 7i of deceleration sensor 7 engages teeth 14c of a lock gear to cause rotation of the reel shaft relative to the lock gear. Thus the main pawl 17 is turned into engagement with the teeth 23a of the lock ring, so that the rotational force of the reel shaft in the webbing unwinding direction  alpha  is transmitted to the lock ring to turn it in the same direction  alpha . This rotation of the lock ring is transmitted through arm 24 to turn a lever carrying a toothed member 26c. As a result, the toothed member 26c bites into the webbing 3, whereby subsequent self-locking action causes the webbing to be clamped between members 26c and 27b. In addition to the main pawl 17 there is a back-up pawl (20, Fig. 4) located at the other end of the reel shaft to engage with teeth (2g) formed on the retractor frame. It is possible to incorporate clamp means to a frame lock type of seat belt retractor, which improves the reliability of part engagement much more. Many other details of the seat belt retractor are disclosed. <IMAGE>
