The process and the device are used for testing electrically insulating protective coatings on metal parts which, together with a backplate electrode, form an electrolytic cell to which current or voltage is applied. The process and device are characterized by the fact that, for quantitative testing of the protective coating, a stabilized current impulse or a constant voltage impulse of short dura...

The device has a humidity sensor made of porous material in which at least one measurable characteristic is changed as a function of humidity. The device covered by the invention is characterized by the fact that it contains a narrow band infrared radiation source (1) which irradiates the humidity sensor (3) from a prescribed distance (S). In this way it is possible to eliminate almost entirely th...

Date Nov. 6, 1986.The detection and identification of metal items is effected by a marginal oscillator the resonant circuit of which has an inductor surrounding a path along which any metal items are caused to travel. The frequency and amplitude changes in the ...

A compensation circuit for a heater wire and a temperature sensor, the temperature sensor generating a signal whose amplitude is dependent upon the amplitude of the voltage across the heater wire. The circuit comprises a comparator circuit and a priority encoder circuit for generating digital information that is a function of the amplitude of the voltage in the heater wire; a multiplexor/demultipl...

The present invention relates to a method of and apparatus for measuring the width of an object. The object is moved across a first beam and a photodetector produces a signal indicating when the object is eclipsing the beam. An interferometer is trained on a device for moving the object across the beam and is used to calculate the distance the moving device travels while the object is eclipsing th...

A corona discharge device having a first corona wire and a second corona wire parallel to the first corona wire and in physical contact therewith, such that the forces created by the wires during energization prevent the vibration of the wires, thereby eliminating short circuiting and the need for costly wire-damping devices.

Apparatus and method are disclosed for electrophotographically producing high quality reproductions from an original document sheet which contains continuous tone (pictorial) and line-type information. The locations of the different content portions of the original are determined using a sonic digitizer that is integrated with the exposure platen. The document sheet is exposed onto each of two ima...

An electrophotographic reproduction apparatus and method are provided for reproducing an original document sheet that includes a continuous tone pictorial information area and a line-type information area. Rather than reproducing the entire document sheet with screening of both types of information, means are provided for selectively screening only the pictorial information area on the reproductio...

An intelligent compiler particularly useful for evaluating Boolean expressions such as those associated with ladder structures. True/false paths are defined through the expressions. In a first pass for the code generation, the start code for examining each element is set out. In a second pass the relative offsets for branching from one element to the next element along both the true and false path...

The method concerns the comparison of a measured speed curve (S) with a reference speed curve (R) of a signature for example. The signals of the reference are read by the rectangle (A) and those of the measured curve are read by the rectangle (B). The measured speed curve is divided into equal segments. The position of each segment of the measured curve is determined with respect to the correspond...

A device for maintaining the vigilance of a motor vehicle operator (22). Two preferred embodiments, maintaining the operator's attention toward the direction of developing traffic conditions, with a visual system focused at infinity, are disclosed. One shows an image (26), unrelated to the motor vehicle (12), which is projected (37-38) or otherwise transmitted from below the normal line of sight o...

Magnetic recording media wherein the record surface is coated with an isocyanate lubricant (and, preferably, a supercoat of like lubricant), such lubrication being adapted to inhibit spin-off and like depletion, despite frequent head-contact, while exhibiting good durability, wear resistance and recording characteristics over extended life (computer applications).

In a method and apparatus for diluting a reaction product, particularly a peracid for sanitizing purposes, reactants from an inlet 75 are reacted in a reaction vessel 3 provided with means 13 for impeding their ingress to minimise turbulence as they mix with the body of liquid within the reactor. An outlet 11 is positioned remote from the impeding means to remove liquid generally having the longes...

What is disclosed is a curable organopolysiloxane composition based on the platinum catalyzed silicon hydride addition to unsaturated groups on silicon, cure system. The novel feature is the use of a silane to enhance the adhesion of the curable material to many substrates. The silane has the general formula 2.
