Abstract: A headlamp system for a vehicle comprises: at least one headlamp which is switchable between at least a high beam mode and a low beam mode, in which the headlamp emits a high beam and a low beam respectively, and wherein said high beam is of higher intensity than said low beam; a biased actuator which is movable by a driver of the vehicle between a temporary-on position and an off position, and which is biased from said temporary-on position to said off position; and a headlamp which is arranged to emit a safety flash when said biased actuator is moved to said temporary-on position; wherein the overall duration of the safety flash is automatically limited to a value which is less than 2 seconds.

Abstract: A process for the production of a polymeric film comprising a copolyester having an acid component and a diol component, said acid component comprising a dicarboxylic acid and a sulfomonomer containing a sulfonate group attached to the aromatic nucleus of an aromatic dicarboxylic acid, said process comprising the steps of: (i) melt-extruding a layer of said copolyester; (ii) stretching the extrudate in at least one direction; (iii) heat-setting the film by raising the temperature of the stretched film to a temperature T1 in a first heating zone such that (TM-T1) is in the range of from 5 to 30° C., and then raising the temperature of the film to a temperature T2 in a second heating zone such that (TM-T2 is in the range of from 0 to 10° C.

Abstract: This invention provides a piezometric device to measure ground water having a fluid container in which the piezometric element is immersed so that it is permanently saturated. An opening above the level of the piezometric element allows fluid in a container to be retained and yet equalized with surrounding ground water to provide pressure readings. This avoids the device becoming unreliable should the water level fluctuate. A releasable seal may be placed over the opening into the container 2 to keep the fluid within the housing during transportation.

Abstract: An exhaust gas catalyst especially for small two-stroke gasoline engines comprises a platinum group metal deposited on a refractory metal honeycomb support and is provided with a diffusion barrier coating which reduces conversion without reducing light-off temperatures. Prolonged catalyst life is shown when exposed to misfire conditions.

Abstract: A product created through the reflow of low melting point solder on select contacts of a printed circuit board. In one form, the printed circuit board has fine pitch devices, including flip-chip integrated circuits, connected to a board having conventional coarse pitch surface. The fine pitch contacts of the board are exposed through holes in a stencil characterized in its ability to withstand solder reflow temperatures, not be wettable by solder, and have a coefficient of thermal expansion relatively matching the printed circuit board. Low temperature solder paste is screen deposited into the stencil openings. With the stencil fixedly positioned on the board, the solder paste retained by the stencil pattern is reflowed to selectively form on the underlying contacts of the printed circuit board. Thereafter, the stencil is removed from the board and the board is subject to previously practiced depositions of flux and paste in preparation for fine and coarse pitch component placement and ensuing solder reflow.
