Patent GB-2176934-A (GB)
Title: Thyratrons
Inventor: MENOWN HUGH
IPC: H01J17/50
Filed: 1986-05-16
Abstract: A thyratron which enables reverse current conduction has an anode 7 and an adjacent anode grid 9 which together enclose a volume 11. A potential difference is applied between the anode 7 and anode grid 9 such that on forward conduction of the thyratron the charge density of plasma in the volume 11 is increased and when forward conduction of the thyratron stops, persists for some time in that space. On reverse conduction, the plasma contained within the volume 11 acts as a cathodic medium. In another mode plasma may be created in volume 11 prior to the thyratron becoming conducting. In other embodiments (Figures 3 and 5) a plurality of enclosures for containing plasma to act as a cathodic medium are provided. <IMAGE>

Title: Improvements in or relating to valves and fluid systems
Inventor: HARDAKER EDWIN JOHN
IPC: B60G17/015
Filed: 1988-06-09
Abstract: A valve 10 comprises a ball 18 movable in a chamber 11 having an end passage 15 and a side passage 16. Acceleration of the valve in the appropriate direction will cause the ball to move to engage valve seat 14 to prevent communication between passages. Two such valves may be connected in opposite senses between two fluid suspension systems e.g. on a vehicle and fluid transfer from the suspension device under compression, as a result of the acceleration, to the suspension device under extension is prevented, thus restricting movement of the suspension devices and the resulting roll or pitch movements of the vehicle. An arrangement with eight such valves in pairs for a four suspension unit vehicle is described. <IMAGE>

Title: Fiber optic safety system
Inventor: ROCKSTROH TODD JAY
IPC: B23K26/08
Filed: 1990-04-12
Abstract: In a system for detecting energy leakage from an optical fiber (16) transmitting high power laser beams, a second optical fiber (26) is placed together with the laser power transmitting fiber into a jacketing tube (3) which may run in conduit (32). The second fiber is connected at one end to a light source (20) and at the other end to a photosensitive diode (28). Leakage of laser energy from the power transmitting fiber will cause a failure of the second optical fiber, reducing or terminating the transmission of light to the photosensitive diode. Energy leakage from the laser power transmitting fiber can therefore be detected by monitoring the output of the photosensitive diode and the laser source shutdown before the beam damages the conduit. …<IMAGE>…

Title: Device and method for evaluating the moulding stability of pieces moulded by an injection molding machine
Inventor: MANABE NORIO
IPC: B29C45/50
Filed: 1991-03-19
Abstract: The injection molding machine (10) has a screw (12) which reciprocates to inject a molten molding material from the cylinder (11) into a metal mold (14). To evaluate molding stability the injection pressure imparted to the molten molding material by the screw (12) at each screw position is detected by respective means (22, 21), for each molded piece, and the detected injection pressure is then integrated to obtain the work done by the machine, and the molded piece so produced is weighed. A correlation between work done and the weights of molded pieces is statistically obtained. Molding stability is then evaluated from the correlation so obtained. Mould temperature changes e.g. at the commencement of moulding, and material viscosity changes, may be assessed from the relationship between the work done and the injection sequence (Figs 5, and 8). <IMAGE>

Title: A downhole installation device and running tool therefor
Inventor: ZWART KLAAS
IPC: E21B47/06
Filed: 1991-06-04
Abstract: The device comprises a running tool 10, an inner mandrel 12 and a bomb hanger 13 secured to the tool for installation downhole below a piece of equipment (not shown) already installed and having a restricted internal diameter, e.g. a safety valve. The running tool includes a long inner probe 11 which extends through the inner mandrel 12 and to which the bomb hanger is attached by shear screws 14, and an outer mandrel device comprising a trip mandrel 15 and a sleeve 18. The trip mandrel carries inner trip keys 17 and outer trip keys 20. The outer keys 20 retract to allow the installation device to pass down through the core of the safety valve but when the device is then lifted the outer keys 20 abut the bottom of the valve. This allows the inner trip keys 17 to release the probe from the mandrel and allow no-go fingers 40 on the bomb hanger to open out. When the device is run downhole the no-go fingers 40 land on the appropriate landing nipple. By jarring down, the screws 14 are sheared to release the bomb hanger from the probe which moves downwards into the bomb hanger to cause lock-out fingers 41 on the bomb hanger to operate. The running tool can then be retrieved and the inner mandrel 12 and bomb hanger remain downhole carrying, e.g. a pressure gauge. A release device 55/56 is provided to enable the running tool to be released and retrieved if the bomb hanger is not properly installed, e.g. if the lock-out fingers do not properly lock-out or if a lock down collet 30 does not function properly. <IMAGE>
