Title: High cis-1,4-polybutadiene rubber compounds
Inventor: BUSH JERRY LEVI
IPC: C08K5/14
Filed: 1999-07-19
Abstract: This invention relates to blends of a specific type of cis-1,4-polybutadiene rubber with other rubbery polymers, such as natural rubber, synthetic polyisoprene rubber, styrene-butadiene rubber, isoprene-butadiene rubber and/or styrene-isoprene-butadiene rubber. The cis-1,4-polybutadiene rubber utilized in the blends of this invention is synthesized by polymerizing 1,3-butadiene in the presence of (a) an organonickel compound, (b) an organoaluminum compound, (c) a fluorine containing compound and (d) para-styrenated diphenylamine; wherein the organoaluminum compound and the fluorine containing compound are brought together in the presence of the para-styrenated diphenylamine. The cis-1,4-polybutadiene rubber blends of this invention offer improved processability and enhanced physical properties. For instance, improved mixing which results in better incorporation of pigments and fillers, such as carbon black and silica, at lower levels of power consumption is realized. Additionally, improvements in extrusion characteristics and in tear resistance with little sacrifice in hysteretic properties, abrasion resistance and modulus are also attained with the rubber blends of this invention. The rubber blends of this invention can be used in manufacturing a wide variety of rubber products, such as tires, hoses, belts, golf balls, tennis balls, racquet balls, golf club grips, stoppers, plungers, tubing, straps, diaphragms, motor mounts, bushings, weather stripping, windshield wiper blades, shoe soles, other molded rubber products and adhesives.
Patent GB-2357197-A (GB)
Title: Capacitor discharge device
Inventor: LIU CHU-KUANG
IPC: H02H3/14
Filed: 1999-11-16
Abstract: A device for discharging charges from a capacitor 1b of a power system includes a discharge loop 20 electrically connected to the capacitor 1b for providing a discharging passageway for the charges to be safely discharged therethrough, and a control loop 30 electrically connected to the capacitor 1b for actuating the discharge loop 20 to discharge at the moment when the power system is suddenly powered off. Charge stored in capacitor 1b can be quickly discharged when the power is switched off or when the power module (22, fig 2) is disconnected from the system. When the power system is powered on, the discharge loop 20 and the control circuit 30 are short-circuited. When the power system is off or when the power module is disconnected, capacitor 1b starts to discharge. Current will flow through resistor 15 and generate a voltage drop at gate terminal G. FET 11 is opened and current is discharged to ground through resistors 18 and 19. Reduces risk of electric shook when power module is extracted from the system.
Patent GB-2345076-A (GB)
Title: Pilot operated pressure equalising mechanism for subsurface valve
Inventor: LEISMER DWAYNE D
IPC: E21B34/00
Filed: 1999-12-09
Abstract: As shown, a flow tube 18, moveable within a longitudinal bore of the subsurface valve, is used to shift a pilot activator 48 within a pilot bore 50 from a closed position (Figure 8) to an open or equalising position as shown. In the open position, fluid below the valve closure member 24 is allowed to pass through a pilot passageway 58 establishing fluid communication between the pilot bore 50 and a cylinder 64 in which a pilot piston 62 is located. Exposure of the pilot piston 62 to fluid pressure from below the valve member moves the pilot piston 62 within the cylinder 64, causing an equalising plug 66 to move to an open or equalising position, establishing fluid communication from below the valve closure member 24 through an equalising passageway 92. The pressure above and below the valve closure member is then equalised through the equalising passageway prior to the opening of the valve closure member by further downward movement of the flow tube 18. Other embodiments are shown in figures 12 and 13 in which the sealing surfaces are made of pliable materials and figures 14-19 in which the pressure is equalised via an internal fluid passageway in the equalising plug.
Patent GB-2345740-A (GB)
Title: Valve control
Inventor: BURGESS ALAN D
IPC: F24D19/10
Filed: 1999-12-23
Abstract: A bottomhole drilling assembly comprises a drillstring pressure modulation valve assembly having a spring 22 which bears against a compensation piston 76 at one end and on the other end against a modulating ram needle 27. The pressure modulation valve assembly (A, figure Ib) is situated between a pressure responsive thruster (34, figure 1a) and a fluid-operated drilling motor (50, figure 1c) attached to a drill bit (40, figure 1c). The thruster is responsive to internal pressure differences between itself and the annulus. The thruster acts by telescoping to add to the weight on bit (WOE) thus advancing drilling. Changes in conditions during drilling cause a pressure drop to occur through the drilling motor which increases pressure in the thruster . This causes positive feedback which advances the drill further and may stall the bit or motor. The modulation valve compensates for such changes to minimise the effect of such changes on the operation of the thruster. Piston 76 can be preloaded, with fluid flowing, before drilling commences. Spring-loaded needle 27 reacts to any pressure changes by varying the pressure difference at orifice 31.

Title: Apparatus for generating an exchange pulse train for use in a telecommunications system
IPC: H04J3/06
Filed: 1980-02-25
Abstract: In order to provide the possibility of interchange of roles of leading and led exchange pulse train generators, an exchange pulse train (T'') of the led generator is synchronized in phase with that (T') of a leading generator. Each generator derives its exchange pulse train (T', T'') from a respective intermediate pulse train (H', H'') by means of a frequency reduction arrangement (BKP, U). Comparison in the led generator (UGN, BKN, UGV, BKV, BKVv) of the exchange pulse trains detects a relative phase lead or lag greater than a given threshold value of the same order as the intermediate pulse train period and, in order to maintain in-phase synchronism, shortens or lengthens (BKR), as appropriate, a half period signal portion of the exchange pulse train by an intermediate pulse train period. The intermediate pulse generator is servo-synchronized by means of a master pulse train derived in a frequency adjuster from a received standard pulse train.
