Patent FR-2495306-A1 (FR)
IPC: G01B3/00
Filed: 1981-10-27
Abstract: In a device for measuring depth or length and having a probe (feeler, gauging, tracer) pin (1) which is guided displaceably and is biased in the sense of extension by a tension (extension) spring (10) acting on it with one end, when the spring length is small a largely constant extension force is maintained even in different extension positions, because the second spring end acts on the shorter lever arm of a pivoted lever (12) which presses in the sense of contraction onto the probe pin by means of a longer lever arm, with the result that when the probe pin is displaced the two points (9, 11) of action of the spring are shifted approximately in the same direction and the change in length of the spring corresponds only to a fraction of the probe pin travel.

Title: Electrically conductive disc rotation meter for e.g. electricity meter - uses aperture in disc and field emitting and field sensing plates to supply data to microprocessor
Inventor: ARNASON JOHN D
IPC: G01P3/483
Filed: 1982-04-06
Abstract: The meter comprises a pair of plates on opposed sides of the disc. A varying voltage is applied to one of the plates (218) and the change in induced voltage on the other plate (220) as the aperture passes between the plates is sensed by a sensing circuit (226). Two pairs of plates spaced from one another about the axis of the disc may be used to eliminate spurious pulses resulting from axial movement of the disc. The sensing circuit may be arranged to generate a signal which is passed to a signal-processor, which in turn generates a number of output signals proportional to the number of signals received from the sensing circuit. The signal-processor can be a microprocessor, which may also supply the varying voltage applied to the plate(s) adjacent the disc.

Patent FR-2528186-A1 (FR)
Title: Fluid jet system for detecting presence of drill - uses thermistor to sense cooling effect generated when fluid strikes object for automatic control of drill
IPC: G01V9/00
Filed: 1982-06-07
Abstract: A monoblock assembly contains a fluid emitting jet whose jet strikes the tip of a drill in its path. The fluid trajectory is altered by the drill when present and this action cools a thermistor housed in the monoblock assembly. The thermistor is powered from an amplifier circuit which is followed by a comparator. The comparator drives an electromechanical stage to operate a relay when a particular threshold temperature level has been achieved. Absence of the drill causes the thermistor to heat because of the absence of the cooling effect created by the fluid jet. This action allows the relay to provide automatic control of the drill.

Title: New carbohydrate analogues, their use in the food industry and process for preparing them
Inventor: DEFAYE JACQUES
IPC: C07H9/02
Filed: 1983-08-08
Abstract: The invention relates to new carbohydrate products which are sugar analogues in the food industry. These products are characterised in that they essentially consist of saccharide anhydrides whose molecule contains two saccharide rings linked to each other via two acetal bonds which are present in a dioxane ring. In general, at least one of the saccharide rings is that of (optionally substituted) fructose and the latter is linked to the dioxane ring via a spiro bond. The treatment of the sugars with a hydrogen halide, and more particularly with hydrogen fluoride, makes it possible to reduce their calorific value and, optionally, to subsequently isolate the carbohydrate analogues according to the invention, which constitute calorie-free food sugars.
