Abstract: Valve operating apparatus is disclosed in which the valves (la,lb) are operated by rocker arms (7,8,9) driven by cams (3,4,5) having different cam profiles and hydraulically operated coupling mechanisms (2l,22) for selectively connecting or disconnecting adjacent rocker arms to vary the operation of the valves under different engine operating conditions. The coupling mechanisms are operated by fluid supplied through the rocker shaft (6) mounting the roker arms. The rocker shaft is divided into independent fluid supply passages (32,33) whereby the couplings can be supplied independently with operating fluid in order to expand the number of available valve operating control modes. Variations are described in which operating fluid can be independently supplied to various auxillary hydraulically-operated equipment, as well as to the selective coupling mechanisms.

Abstract: A method is provided of producing a self-supporting ceramic composite structure having one or more encasement members (14), such as an encasing stell sleeve, joined to it by growth of the ceramic material to engagement surface(s) of the encasement member(s) (14). A parent metal is contacted with a body of filler (38) which is encased by the encasement mmber(s) (14). The resulting assembly is heated to melt and oxidize the parent metal, e.g., aluminum, to form a polycrystalline material comprising an oxidation reaction product which grows through the body of filler (38) and stops at the engagement surface(s) of the encasement member(s) (14) which thereby determines the surface geometry of the grown ceramic matrix. Upon cooling, the encasement member(s) (14) is shrinkfitted about the ceramic composite body. The invention also provides the resultant articles, for example, a ceramic composite body having a stainless steel member affixed thereto.

Abstract: 1. Process and device for the atomisation of at least one jet of a liquid, preferably molten metal. 
<??>2.1. Known methods and devices of the type concerned here have poor atomisation performance and consequently slow cooling of the atomised metal particles or the like. This leads to unfavourable grain formations. The process according to the invention and a corresponding device are intended to obviate these disadvantages. 
<??>2.2. As regards the process, it is proposed to atomise the molten metal particles or the like in a compressed gaseous medium, which offers a higher energy transfer for the ultrasound employed. It is furthermore proposed, as regards the device, to employ a plurality of ultrasonic oscillators (12). By superposition, these produce a (common) ultrasonic field (27) with a high energy density in the nodal region (29). This gives more intensive atomisation and an associated improvement in the quenching rate. 
<??>2.3. The method proposed and the corresponding device are particularly suitable for producing specific materials or objects composed of these materials.

Abstract: A process for making an absorbable, annealed surgical device made from a multi-phase, polymeric composition derived from lactide and glycolide is disclosed. The device has a high distortion temperature, good resistance to hot wet creep, but yet loses tensile strength in vivo quickly. The composition per se is injection-moldable, can be annealed, and is not brittle. The process of the invention comprises polymerizing a first monomer mixture containing a predominant amount of lactide, followed by polymerization of a second monomer mixture in the presence of the first monomer mixture. The polymer is then formed and the surgical device annealed. The first monomer mixture contains a predominant amount of lactide and the second monomer mixture contains glycolide.

Abstract: A flame sensing digital primary safety control for fuel burning devices and method therefor are disclosed. A photocell senses the presence or absence and the condition of the burner flame. A DC control signal for the primary safety control is generated under a "dark start" condition in the fuel burning device. Once proper ignition of the fuel has occurred, safety control is transferred to an AC "normal flame" signal that is obtained from the photocell. The use of an AC safety control signal provides a greater degree of safety for the fuel burning device because problems with the photocell, such as a shorting of the cell, produce a "fail safe" condition in contrast to a DC signal operated safety control.
