Title: Surface discharge spark plug for i.c. engines
Inventor: TINWELL PAUL
IPC: H01T13/52
Filed: 2000-04-10
Abstract: The spark plug includes a central high voltage electrode (3) extending within an insulator body (2) and having an exposed portion (3a) protruding from a lower end (2a) of the insulator (2). A ground electrode (4) is mounted on the insulating body with a small longitudinal spacing (12) from the lower end of the insulator (2) such that a spark gap is defined between the two electrodes with a longitudinal component alongside a lower end region (2a) of the insulating body. In operation, a spark produced between the two electrodes runs along a surface area of the lower end region (2a) to ignite the fuel-air mixture. The spark plug has enhanced performance, particularly in ignitability, anti-fouling performance and extended life. Since the spark plug exhibits reduced capacitance so that its associated ignition coil assembly can be of reduced external dimensions, it is possible to locate more of the ignition coil assembly, or the whole of it, within the bore formed in the cylinder head of the engine, so as to provide a more compact arrangement for the ignition system of the engine.

Title: Continuous process for the production of carboxylic acid esters of alkylene glycol monoalkyl ethers
Inventor: GERBERICH H ROBERT
IPC: C07C67/08
Filed: 1997-10-31
Abstract: The present invention provides an improved method for the preparation of carboxylic acid esters of alkylene glycol monoalkyl ethers by the acid catalyzed esterification of the monoalkyl ether with a carboxylic acid. In a preferred embodiment of the invention, the carboxylic acid and alcohol are reacted in a reactor/column and the resulting ester product is distilled into an overhead decanter/extractor as a single phase. A small amount of solvent, preferably a hydrocarbon is added to the mixture causing the resulting distillate to separate into two phases, one phase containing the desired product, the other containing primarily water. The process described is applicable to both batch and continuous operation and is not constrained by the difficulty of separating closely boiling azeotropes and results in substantially higher production rates than achieved by current processes.

Title: A laser cavity including a lyot filter
Inventor: COX ALAN
IPC: H01S3/16
Filed: 2001-10-30
Abstract: A laser cavity comprises a gain medium 1 and a first and second end mirrors 3,4. The laser cavity further comprises a birefringent frequency-doubling material 5 and a mirror 2 arranged to fold light propagating within the laser cavity though a predetermined angle, wherein the predetermined angle is selected such that the reflectivity of the fold mirror 2 is polarisation dependent, and the birefringence of the birefringent material 5 co-operates with the polarisation dependent reflectivity of the fold mirror 2 to form a Lyott filter which suppresses oscillation of unwanted laser modes. The invention allows the construction of a low loss, high finesse laser cavity with longitudinal mode control. The need for introduction of an extra polarisation selection element to form a Lyott filter is removed. The gain medium 1 may be Nd:YAG, Nd:YVO4 or Nd:YLF. The material 5 may be KTP, LBO or KNbO3.
Patent GB-2369637-A (GB)
Title: Apparatus and method for controlling fluid flow
Inventor: MALONE DAVID L
IPC: E21B21/10
Filed: 2000-06-27
Abstract: A choke system or valve assembly includes a valve having an orifice (170, 190-194) through which fluid flow can be choked or controlled. An actuator (114, 152) positions the valve at one or more incremental positions (170A-170E) between an open position and a closed position. The valve, orifice (170), and actuator (114, 152) provide a substantially consistent (or otherwise predetermined) change in pressure drop and flow rate between different valve positions by varying the flow area of the valve orifice (170, 190 - 194) non-linearly as the valve is shifted through several positions. Another feature is the ability of the actuator (114, 152) in conjunction with an indexing mechanism (100, 102) to provide precise control of the valve orifice through the several valve positions. The indexing mechanism includes an indexer device (100) to index the actuator through the several positions and a positioner device (102) to maintain the valve at a fixed position after the actuator has shifted the valve to the next incremental position.
