Abstract: ABSTRACT OF THE DISCLOSURE      Metal catalysts for use in known heterogeneous catalysis processes are prepared by vaporizing a metal in a low pressure environment in the vicinity of an organic liquid polymer, so that the metal contacts and becomes anchored to the polymer.  The resulting products have the metal in the form of small clusters, anchored to the poly-mer, this form of the metal being the catalytically most active form.  The organometal polymers are stable at temperatures in the -40°C?+40°C range.  Suitable polymers include poly (methyl-phenyl siloxanes) and poly (phenyl-ethers). Suitable metals include titanium, chromium, molyb-denum, etcetera.

On one face end the mould core has a mould core portion which projects axially beyond the ends of the teeth and forms a holding surface, whose diameter is constricted to the diameter of the tooth notches.  The edge of the fabric cover which projects axially beyond the teeth is tightly bound and secured sealingly on the holding surface of the mould core portion.  At the end of the mould cavity on which the mould core portion containing the secured fabric cover edge rests the plastic material is axially introduced into the mould cavity.

Abstract: TWO-STROKE INTERNAL COMBUSTION ENGINE AND        METHOD OF OPERATION THEREOF           ABSTRACT OF THE DISCLOSURE     An internal combustion engine comprises a combustion chamber and a piston movable relative to the combustion chamber between top dead center and bottom dead center positions.  A fuel transfer passage introduces fuel-air mixture into the combustion chamber in response to piston movement.  An auxiliary chamber is also provided which is communicable with the combustion chamber in response to piston movement shortly after the ignition of a fuel-air mixture, such that high pressure ignition gases enter the auxiliary chamber.  The high pressure ignition gases thereafter flow back into the combustion chamber in response to piston movement before communication is established between the combustion chamber and the fuel transfer passage.  The incoming flow of high pressure ignition gases serves to influence the normal scavenging streams.  The auxiliary chamber can also function as an auxiliary transfer passage in response to piston movement to supplement the fuel transfer passage in supplying a new fuel-air mixture charge to the combustion chamber.  In one embodiment, an air transfer passage is provided for introducing fresh air into low pressure regions in the cylinder to lend overall stability to the scavenging process.

Abstract: ABSTRACT OF THE DISCLOSURE           A well-logging method and apparatus for detecting the first arrival of an acoustic wave in a logging signal under adverse signal conditions.  The received acoustic signal is amplified at a fixed gain until clipped at the largest amplitude throughout the logging procedure.  This amplified signal is converted RMS to DC level signal and stored in sample and hold means for a period shortly before first arrival of the acoustic wave.  The continuing DC level signal and the stored DC level signal are compared to pro-duce a comparator output DC signal when the continuing DC signal has a certain increased magnitude.  This certain increased magnitude is used to generate a pulse of given magnitude and duration that is especially suitable in di-gital data systems.
