Abstract: 1. A process for inspecting and automatically sorting objects showing patterns with dimensional tolerances and reject criteria varying in accordance with the location of said patterns, of the type including the comparison of the image of a reference object with the image of an object to be inspected, the latter being liable to show geometrical defects with respect to the reference object, characterized in that it includes the following steps : - Elaborating binary electronic images IREF and IEXA from the reference object and the object to be inspected, - Defining a structuring element B for each image point (pixel), the size of said structuring element being able to vary for each pixel in function of predetermined data and adjusting IREF to the maximum and minimum dimensional tolerances by expanding and eroding said image by means of structuring element B, which provides (IREF )max and (IREF )min , - Forming images of the "spreading" and "lack" type defects by respectively carrying out the following logical operations : [(IREF )max OR IEXA ] EXCL. OR (IREF )max and [(IREF )min OR IEXA ] EXCL. OR IEXA , - Measuring the size of the defects on the defect images and comparing said defects with respect to reject criteria which define, for each pixel, the dimensions of the defects which can be accepted according to predetermined data, and - Sorting and selecting objects without any defect or showing defects allowed by the reject criteria.

Abstract: A solar heating system includes an absorber panel (1) connected to a water supply tank. A valve (10,11) is located in each of feed and exhaust connections (3,6) and at least the inlet valve (10) is temperature responsive so as to close when the temperature of the panel contents falls below a first predetermined temperature. The outlet valve (11) may be temperature or flow responsive so as to close under the temperature or flow conditions prevailing when the inlet valve (10) closes and thereby isolate the panel (1) from the tank (2). A temperature responsive dump valve which may be incorporated in the valve (10) is connected to the panel (1) and opens when the temperature of the panel contents falls below a second predetermined temperature which is lower than the first predetermined temperature and thereby empties the panel contents. The combined inlet and dump valve (10) has a temperature responsive element which controls both a primary valve member and a secondary valve member. The primary valve member controls flow between inlet and outlet ports (13,14) of the valve (10) and the secondary valve member controls flow between the outlet port (14) and a dump port (12). The temperature responsive element has a part exposed externally of the valve body and is substantially insulated against the influence of temperature conditions existing within the body of the valve (10).

Abstract: Disclosed is a process for machining nickel-base superalloys wherein a thermal-effect process, such as laser or electric discharge machining, is first used to remove material but leaves a recast layer. Next a chemical milling process is used wherein the etchant only attacks and removes the recast layer. The etchant is comprised by volume percent of 40-60 HN0 3 , 5-20 HCI, and 20-55 H 2 0, with which is included 0.016-0.025 moles/liter FeCl 3  and at least 0.008 moles/liter CuS0 4 . The FeCl 3  improves removal rate but tends to cause unwanted pitting and intergranular attack. These tendencies are inhibited by the addition of CuS0 4 ; preferably the molar ratio of CuS0 4  to FeCl 3  is 2:1. The beneficial combination of FeCl 3  and CuS0 4  is usable in other etchants.

Abstract: The present invention relates to coherent poly(acetylene) films and to a method of producing such polyacetylenes. The process comprises solvent casting a solution of a polymer of the general formula (V) derived from a precursor (IV), and transforming the pre-cast, polymer (V) into a poly(acetylene) (III) film and a by-product (VI) at a temperature between 20 DEG  and 200 DEG  C. at reduced pressure. The poly(acetylene) thus formed has a substantially higher density than the poly(acetylene) polymers produced hitherto. The morphology of the poly(acetylene) produced is that of a thin, coherent solid film with no voids and, no basic structural units are visible even at a magnification of 10,000 times. The polymers also have a lower crystallinity than those produced by conventional methods.

Abstract: A stimulable phosphor sheet carrying a radiation image stored therein is scanned with stimulating rays which cause the stimulable phosphor sheet to emit light in proportion to the radiation energy stored therein. The emitted light is photoelectrically detected to obtain sequential electric signals of respective picture elements of the radiation image. The interference among the electric signals of the respective picture elements which is caused by the light emission response characteristics of the stimulable phosphor to the stimulation is eliminated electrically. The correction is conducted by adding a differentiated value of the sequential electric signals of the respective picture elements to the sequential electric signal of the respective picture elements
