Abstract: Abstract of the Disclosure An optical micrometer scans an article passing through its zone of measurement to provide a series of pulses representing the dimension of an article.  Each new measurement is compared against a previous measure-ment, or an average of a predetermined number of previous measurements, and the difference is then compared to a previously established deviation limit.  If this dif-ference does not exceed the deviation limit, then the new measurement is transferred to the output of the circuit for utilization by the system, but if this dif-ference exceeds the deviation limit, then the previous measurement signal will be transferred to the output. An alarm is provided whenever a predetermined number of new measurement signals outside the deviation limit occur within a certain number of measurement intervals.

Abstract: ABSTRACT OF THE DISCLOSURE             Method of extracting, measuring and adding a product. The subject matter of the present invention is a method of extracting and measuring a product and adding said product to a product contained in a hopper. The method, according to the invention, of extracting and measuring out a product from a bulk stock and adding said product inside a hopper is essentially charac-terised in that it uses at least three perforated surfaces or plates superimposed on one another and in contact with one another so that the product to be extracted is trapped in the hole(s) in the centre plate between the top plate and the bottom plate by a relative movement of the top plate in relation to the two other plates then stationary in relation to each other and the product so trapped in the hole(s) in the centre plate is extracted to the outside by a relative movement of the centre plate in relation to the top plate and the bottom plate, then stationary in relation to each other, or by a relative movement of the bottom plate in rela-tion to the centre plate and the top plate. The addition and mixing of the additive so extracted with a product contained ina hopper, which products may be a pigment and a plastic in granules in a hopper,is done by making a cavity in the bulk of the product contained in the hopper in an area close to its delivery nozzle and by pouring through the bulk of said product, from one or several distributors controlled by the device fed by the hopper, the additive(s) into the cavity for mixing there, which avoids dirtying the whole of the hopper and makes better and more proportionally accurate mixingpossible. The method according to the invention and the devices for putting it into effectare particularly useful when small grain or powdered products have to be measured, as is particularly the case in the plastics processing industry.

Abstract: ABSTRACT OF THE DISCLOSURE             The invention provides a peripheral vision horizon device for use in projecting a light bar on the interior of an aircraft cockpit or the like to indicate pitch and roll, the light bar being located with refer-ence to a datum in the cockpit.  The device includes a housing having a first part attachable to the cockpit and a second part rotatably coupled to the first part for movement about a first axis which on assembly in the air-craft extends transversely of the cockpit.  A lens carrier is rotatably coupled to the second part for rotation about a second axis which is at right angles to the first axis. A light source is contained in the housing and an optical system is coupled to the housing for directing light from the light source towards the lens carrier along the second axis.  A lens of two-fold symmetry is mounted in the lens carrier transversely of the second axis for receiving said light and projecting a beam of light which strikes the interior of the cockpit to create the light bar.  Con-trol means are also coupled to the housing, the control means being operable to move the second part about the first axis to indicate pitch and to move the lens carrier about the second axis to indicate roll.  Consequently, deviation of the position of the light bar from the datum will indi-cate the orientation of the aircraft relative to a horizon-tal plane containing the light bar.
