Abstract: The silicone rubber composition is characterized by the formulation of a novel organic peroxide as the curing agent which is a bis(4-organosilyl-substituted and 2- and/or 6-substituted benzoyl) peroxide such as bis(2-methyl-4-­trimethylsilyl benzoyl) peroxide and bis(2,6-dimethyl-4-­trimethylsilyl benzoyl) peroxide. The silicone rubber composition is suitable for hot air vulcanization without compression to give a cured rubber having no surface tacki­ness and free from voids. The cured silicone rubber article is outstandingly superior in respect of the resistance against aging in high-temperature steam and low permanent compression set to the silicone rubber cured with 2,4-­dichlorobenzoyl peroxide which is the only peroxide curing agent usable in hot air vulcanization.

Abstract: The flow rate of every amount fed out of a particular storage container (1-4) by a feed device (5-8) is measured by a flow meter (10). The flow rate is regulated by means of a regulator (9). If the actual value of the flow rates of every individual component is not equal to the setpoint value, all the flows are fed back to the respective storage container (1-4) via the reversing valve (11) and the return line (12). If all the actual values are equal to the setpoint values, the reversing valves (11) switch over so that the individual components are fed to the mixer (13) via the feedline (14). The mixture produced is again analysed in measurement units (18-20). If the actual values found by analysis are again not equal to the analytical setpoint values, the reversing valves (11) are in turn immediately switched over to the return line mode. Consequently, it is no longer necessary to remove a mixture which has not been further processed, that is to say the product, as waste during the period of time in which the control circuits are stabilising. On the contrary, the individual components are again fed back to the storage tank (1-4) so that no product loss can occur and a higher quality standard of the product can be achieved.

Abstract: The invention relates to a pulmonarily actuated valve (1) for overpressure operation in the interior of a protective breathing mask, consisting of a valve housing (2) having a spring-loaded control diaphragm (8), which subdivides the valve (1) into an outer chamber (16) connected to ambient pressure and a breathing chamber (17) carrying the breathing gas, the control diaphragm (8) controlling an inlet valve (6) for the breathing gas via a manually released control button (11) and a lever device (13, 14). The invention solves the problem of preventing unintentional release or switching on of the valve from the rest position into the operating position in the event of external vibrations. This is done by virtue of the fact that in its central region the control diaphragm (8) has an elastic protuberance (9) with a depression (9a) into which in the event of release of the control button (11) a tappet (12) integrally formed thereon can lock home positively and carry along the control diaphragm (8) with the protuberance (9) into a recess (24), arranged above the control diaphragm, of an insert (10). In this connection, the protuberance (9) is supported in the recess (24) lying tightly against it.

Abstract: A method is provided for the preparation of stable aqueous dispersions of non-solvated, un-neutralized, low amine, low acid number polymerized fatty acid polyamide resins. In the preferred method of this invention, a polymerized fatty acid polyamide resin which has been prepared so as to have a low acid and low amine number is liquified by heating the polyamide resin to a temperature where it is at or above its melting point. The liquified polymerized fatty acid polyamide resin is then blended with a predetermined amount of water which is heated to a temperature such that the resulting blend will have a temperature above the melting point of the polyamide resin. A surfactant which will promote the emulsification of the polyamide resin and water is included in the mixture. The resulting mixture is then subjected to sufficient comminuting forces to form an emulsion in which droplets of the polyamide resin have a volume average size distribution of about 20 microns or less in diameter and preferably 5 microns or less. The resulting emulsion is then cooled to a temperature below the melting point of the polyamide resin causing the emulsified droplets of the polyamide resin to solidify as finely divided particles which are dispersed uniformly through the aqueous   phase. The resulting stable aqueous dispersions of the polymerized fatty acid polyamide resin which are obtained are especially useful for hot melted adhesive applications, and when utilized in coatings, inks, and the like.

Abstract: PROGRAMMABLE TILES 
     A set of functional components (tiles), consist in part of subgate elements, which, by their design, facilitate the creation of dense integrated circuits, without forfeiting the capability of modifying the functionality of individual tiles by late mask programming techniques. Overall densities approaching those obtained with hand-crafted, custom designs can be obtained in part because such components are designed to be tiled throughout a storage logic array, permitting the creation of orthogonal logic gates as well as individual gates (and more complex functions) the functionality of which is distributed horizontally, vertically and even in a zigzag fashion. Moreover, the transition time from prototype to high volume manufacturing is reduced significantly due to the ease with which even complex functions can be repaired and enhanced.

Abstract: An object placement method and apparatus which obtains efficiency and optimized placement by providing a library of object placement patterns, each pattern in said library representing a plurality of objects filling a pattern line or series of pattern lines of a three-dimensional space. For each pattern line, a first type object (for example, a first size object) to be placed is selected and the pattern which minimizes the portion of the three-dimensional space used to place a number of first type objects, subject to at least one constraint factor, is determined. A representation of the objects in the rows according to the determined pattern may be provided. According to another aspect of the invention, linking restrictions between the objects of differing sizes may be provided. The linking restrictions are patterns from the library which may not be employed with objects of differing types in a line of the three-dimensional space. The linking restrictions may reject patterns that lead to irregular pattern geometries, inefficient use of space, unstable characteristics or any other undesirable configuration of the two object types in a single pattern line. The element placement technique of the present invention determines the patterns which minimize the portions of the three-dimensional space used to place the objects consistent with at least one constraint factor without violating the linking restrictions.
