Title: Method for the protection of valves
Inventor: VINE GEOFFREY ALBERT
IPC: F16K27/02
Filed: 1991-07-03
Abstract: A method for the protection of valves of the through conduit type against the ingress of debris prior to actuation involves internally coating the bore of the valve with a suitable material. Once actuated the protective material tears and becomes detached from the valve bore. Suitable materials include silicone polymers, wax based coatings, epoxy coatings, bitumens, rubber and adhesive tapes. The method is particularly suitable for ball valves in oil and gas pipelines and may be applied at manufacture or before installation. The method of application may be by brush spray, injection or hot dip processes. The gaps in the valve may be filled with an anti-corrosion lubricant prior to the application of the coating.

Title: Cable testing
Inventor: MURPHY DAVID CHRISTOPHER
IPC: G01R31/02
Filed: 1993-08-20
Abstract: A major characteristic which determines the suitability of a local network for digital transmission is the attenuation at 40KHz which should not exceed 37dB. Testing which can be carried out at the exchange enables the attenuation to be determined by measuring:   (a) the capacitance as seen between the two wires of the twisted pair and between each wire of the twisted pair and earth and hence calculating the actual capacitance C between the two wires of the twisted pair; (b) the resistance of the loop with the subscribers terminal equipment off hook and subtracting therefrom a nominal value for the resistance R of the terminal equipment; (c) the leakage between the two wires of the twisted pair and between each wire of the pair and ground and hence determining the total leakage G; and estimating the inductance L as seen between the two wires of the twisted pair and hence calculating a value for the attenuation q using the formula:- <IMAGE>

IPC: F16K5/16
Filed: 1995-09-05
Abstract: In a rotary valve having a tapered closure plug 4, a spring 26 co-operates with the plug 4 through an adjustable mechanism to provide a resilient stop which limits movement of the plug away from engagement with the valve seating surface of a tapered valve chamber. A collar 22 is adjustably screwed onto a drive shaft 12 (Fig. 2) or a tubular portion 70 of the spring 26 (Fig. 7), its position being locked by a grub screw 31. Upon movement of the plug towards and away from the spring, the collar is brought into and out of abutment with the other of the spring and the plug. Alternatively, the collar may be screwed into an aperture in a spring beam (106) (Figs. 10, 11, not shown) supported externally of the valve body. In a modification (Fig. 12, not shown), a stack of disc springs is accommodated in a hollow drive shaft and adjustably loads a thrust rod which confronts the wider end of the plug 4. <IMAGE>

Title: Electronic purse loan system
Inventor: NONAKA TOMOYUKI
IPC: G06Q30/06
Filed: 1996-07-30
Abstract: The sum of the former loan of the user of an IC card is written to a personal information storage provided at a center and when the IC card is inserted into the slot of an electronic purse terminal at the time of the next transaction, the sum of the loan stored in the personal information storage is cleared and this loan is paid. At this time, the sum stored in the sum information storage of the IC card is updated by this payment and is stored as the balance in the sum information storage. If the balance is more than the charge for a transaction, the transaction is effected and if the balance is less than the charge for the transaction, the transaction is performed by having a new loan. The sum of this loan is stored in the personal information storage in the center. As described above, the suspension of a transaction due to the shortage of a balance can be avoided by providing a function for loan to an electronic purse system. The system may be used in paying for hire of films, payment for goods at a POS terminal, or payment of fares.

Title: Ground fault circuit interrupter
Inventor: LEGATTI RAYMOND H
IPC: H02H3/33
Filed: 1993-07-14
Abstract: A ground fault circuit interrupter (GFCI) is provided that can be used in single phase or polyphase systems, with a range of input voltages from 70 to 264 volts AC, frequencies of 50 or 60 hertz, and ground fault trip currents of 6 to 30 milliamperes. A leading power factor circuit (33) is connected to the secondary winding of the GFCI differential transformer (23) to permit the magnetic circuit to respond to pulsating DC signals. Provision is made for continuing to provide GFCI protection in the event of an open neutral lead (13), with a timing circuit (81, 83, 85) to prevent current flow to the ground lead (15) until current flow in the neutral lead (13) is completely discontinued. Various types of circuit interrupting devices, such as a circuit breaker or a power converter, may be selectively utilized. A further secondary winding and switch means is incorporated in the differential transformer which may simulate a ground fault in order to test the interrupter. A time delay means prevents current surges from flowing to ground and thus creating a ground fault in associated GFCI's.

Title: Circuit for charging a capacitive load
Inventor: HEFTMAN GEORGE
IPC: H02M3/338
Filed: 1997-10-24
Abstract: A capacitor 4, which discharges into a xenon tube 5 that is triggered recurrently by a pulse generator 6, is charged incrementally between triggering from flyback current within primary 9 and secondary 8 windings of a transformer of a converter circuit 1. The primary winding 9 forms the collector load of a transistor 11 that switches between conduction and non-conduction in dependence upon feedback via a tertiary winding 10 of the transformer. The voltage applied to the base-emitter circuit of the transistor 11 is limited by a zener diode 18 connected in series with a shunt-connected capacitor 19 and diode 20. The zener diode 18 conducts in the reverse direction during flyback voltage induced in the winding 10 to discharge the capacitor 19 incrementally for stabilising the charged voltage of the load capacitor 4 against variation of input DC voltage. A DC restoration circuit 21-23 supplies base current to the transistor 11 from the tertiary winding 10, and capacitors 24, 25 provide further circuit stabilisation.
