Patent GB-2278445-A (GB)
Title: Flow meters
Inventor: SVOBODA KAREL
IPC: G01D5/22
Filed: 1993-05-18
Abstract: A fluid flow meter comprises a conduit 2 within which an orifice plate 8 is secured having an opening 10. An axially slidable contoured plug 12 provides a variable restriction to the size of the opening 10. The plug 12 is biased in the upstream direction by a spring 22 such that the position of the plug is responsive to the fluid flow rate in the conduit. The position of the plug is measured by a transducer 13 comprising a ferromagnetic shaft 18 which is attached to the plug and which has a semi-circular cross-section, the orientation of which varies along its length, and a fixed ferromagnetic sensor body 24. The sensor body has a primary coil 42 and secondary coils 38, 40, the induced voltages in which are dependent upon the axial position of the shaft 18 (and therefore the plug 12), and thus give an indication of the flow rate. <IMAGE>

Title: A driving circuit for use in a display apparatus
Inventor: MATSUMOTO TOSHIO
IPC: G09G3/36
Filed: 1993-11-23
Abstract: A driving circuit for use in an active matrix liquid crystal display apparatus for transmitting a video signal to data lines (S1, S2, ..., Sn) includes a plurality of shift registers (11, 12, 13, 14); a control signal generating circuit (51, 52,..., 5n) for outputting a control signal which is at the ON level during a period shorter than a pulse width of signals outputted by the shift registers (11, 12, 13, 14); a switching circuit (21, 22, ..., 2n) controlled to be ON or OFF based on the control signal; and a sampling capacitor (41, 42, ..., 4n) for holding the video signal sampled by the switching circuit (21, 22, ...; 2n). In such a driving circuit, the plurality of shift registers (11, 12, 13, 14) sequentially output signals so that the periods in which the signals are high are partially overlapped sequentially. The control signal generating circuit (51, 52, ..., 5n) outputs a control signal which is at the level during a period shorter than the signals from the shift registers (11, 12, 13, 14). Since the switching circuit (21, 22, ..., 2n) is controlled to be ON or OFF based on the control signal, a period in which the switching circuit (21, 22, ..., 2n) is conductive is short. Accordingly, the number of such switching circuits (21, 22, ..., 2n) which are simultaneously conductive is small, thereby applying a capacitance of only a small number of capacitors (41, 42, ..., 4n) to a video signal line. <IMAGE>

Abstract: A method for measuring the swing time of a golfer's swing and selecting a golf club having the inverse of four times its natural frequency approximately equal to the swing time. The golfer's swing time is defined as the time elapsed between maximum acceleration of a club head during downswing until ball impact. In the preferred embodiment, an accelerometer is mounted within the club head and is connected to an electronic data processor. A graph of club head acceleration versus time is plotted and the swing time is measured from the graph, between peak acceleration and ball impact which may be determined by means of a piezo-electric crystal.

Patent GB-2298281-A (GB)
Title: Differential pressure transducer
Inventor: BURFORD DENNIS WILLIAM
IPC: G01L13/02
Filed: 1995-02-21
Abstract: A capacitive differential pressure transducer has two mechanically similar sensor parts A, B, each comprising a first chamber 18 and a second chamber 19 separated by an electrically conductive diaphragm 15. An electrode 12 is secured in each of the first chambers 18, in close proximity to one side of the respective diaphragm 15 and electrically insulated therefrom to form a capacitance with the diaphragm. The two sensor parts are positioned in like orientation and rigidly conjoined to each other. Fluid corrections 16,17 apply a first fluid pressure to the first chamber 18A of sensor part A and the second chamber 19B of the other sensor part B, and a second fluid pressure to the second chamber 19A of the one sensor part A and the first chamber 18B of the other sensor part B. Because of the mechanical similarity and like orientations of the two parts A, B of the sensor, an electrical measurement of the relationship between the two capacitances (e.g. using a diode pump circuit - Fig.5) provides a differential pressure measurement which is substantially immune to errors induced by forces acting on the diaphragms 15A,B owing to their mass. As shown each part A,B has an upper body part 8 in the form of a cranked conductive ring and a lower body part 14 in the form of a short cylinder with a closed bottom. The parts 8,14 are bolted together with the diaphragm 15 held therebetween. A ring 16 insulates the electrode 12 from the upper body part. The electrodes are connected to a circuit board 20; a conductive plate 21 provides screening.

Title: Method and device for fire extinguishing by alternating a liquid fog and a liquid jet
Inventor: SUNDHOLM GOERAN
IPC: A62C3/02
Filed: 1993-09-14
Abstract: The object of the invention is to provide a new method for fighting fires, which method requires a small amount of extinguishing liquid for extinguishing a fire and for preventing reignition. When fighting fires in apartments and the like the fire is a first suppressed by spraying fog-like liquid, and thereafter a concentrated liquid spray is directed into the smouldering fire seat. For this purpose it is suggested to use a pistol-like extinguisher (1) with a hydraulic accumulator (5) as a drive unit and provided with a spray head (3) which at first, when the pressure in the hydraulic accumulator is high, produces a fog-like liquid spray and later, when the pressure in the hydraulic accumulator is reduced, produces a concentrated liquid spray. When fighting fires which develop intensive heat the fire is first suppressed by spraying a water jet from a relatively long distance, and thereafter extinguished by spraying a liquid fog at close range. For this purpose it is suggested to arrange, in parallel with a fog-producing spray head, a separate nozzle for producing a forceful, concentrated water jet. To shift from spraying liquid fog to spraying water jet and vice versa, a conventional valve can be used. <IMAGE>

Title: UV and electron beam curable propenyl-ether siloxanes
Inventor: CRIVELLO JAMES VINCENT
IPC: C09J7/02
Filed: 1996-08-21
Abstract: Silicone release agents comprising propenyl-ether functionalized silicones exhibit a rapid cationic induced photo-cure. Such propenyl-ether functionalized silicones are synthesized by the hydrosilation of various * small Greek alpha *-allyloxy-* small Greek omega *-(1-propenoxy)alkanes with various linear and cyclic hydrogen functional siloxanes. The functional group is of the formula Me-CH=CH-O(CH 2 ) x -O(CH 2 ) y -  where  x is a non-zero integer and y is zero or an integer.  The siloxanes are proposed by hydrosilation of a siloxane with a propenyl * small Greek alpha *-alkenyl diether of an alkanediol. The * small Greek alpha *-alkenyl group (preferably allyl) reacts preferentially whereas the propenyl group undergoes rapid photo-curing.

Title: Recovering colliding radio packets in a multiple access communication system
Inventor: WALES STEPHEN WILLIAM
IPC: H04B7/185
Filed: 1996-11-18
Abstract: A packet radio system is provided with a multiple access scheme which operates to schedule transmissions of data bearing radio packets on a common communications channel 5 from a plurality of users 1,2,3 to a common receiver 6 of the system. The radio packets via which the plurality of users communicate include synchronisation data, wherein if a packet is transmitted on the same channel, and chronologically overlapping with other packets on that channel, each packet uses substantially different synchronisation data. The common receiver includes a multi-user detector in which contemporaneously transmitted packets may be detected and recovered in dependence upon the synchronisation data, thereby substantially increasing a throughput of the packet radio system. Also mentioned is the use of trellis coded modulation and the subsequent resolution of multiple data packets in dependence upon both the synchronisation and trellis codes.

Title: Polymer coatings for metal oxides
Inventor: THORNTON GEOFFREY
IPC: C08K9/08
Filed: 1997-01-31
Abstract: Thiophene in the liquid phase is polymerised by being held in contact with a film or substrate of ferric oxide. Other monomers which undergo oxidative polymerisation may be used, and other oxide films may be substituted for ferric oxide provided their redox potential is sufficiently positive to cause polymerisation of said monomer. The oxide film may be on a substrate of the related metal, i.e. iron or steel for ferric oxide. The polymer layer thus formed is useful for corrosion protection, and may be electrically conductive.
