Abstract: ABSTRACT OF THE DISCLOSURE A process is provided herein for preparing structural components. The process includes first forming a slurry containing a hydraulic binding agent, water, additives and an organo(poly)siloxane of the general formula   where at least 10 percent of the number of R radicals are the same or different alkyl radicals having at least 4 carbon atoms per radical and the other radicals when present are alkyl radicals having from 1 to 3 car-bon atoms per radical and/or phenyl radicals, R' represents the same or different alkyl radicals having from 1 to 4 carbon atoms per radical, x is 0, 1, 2 or 3, with an average of from 0.9 to 1.8, y is 0, 1, 2 or 3, with an average of 0.01 to 2.0 and z is 0, 1, 2 or 3, with an average of from 0.00 to 0.5, with the proviso that the sum of x + y + z may not exceed 3.5, preferably not more than 1.5.  The slurry is then molded and, thereafter, the molded slurry is exposed to aqueous steam.  With the same amount of organopolysiloxane, building blocks or structural components prepared as described above and bonded or hardened with the aid of aqueous steam, exhibit much improved hydrophobicity in which the hydrophobicity is more even distributed on the surface or within the structure of the building blocks or structural components.  Moreover, the pores are better  dis-tributed throughout the structural components and subsequent to bonding or hardening they can be more easily coated, for example with bitumen, than building blocks or structural components prepared heretofore containing silicone oil and then bonded or hardened with the aid of aqueous steam.

Abstract: PULSE WITH MODULATED FUEL METERING SYSTEM            ABSTRACT     A fuel metering system for a gas turbine engine with a low pressure drop fuel vaporizing system includes an engine driven centrifugal pump (10) supplied with fuel at a given absolute pressure (Pi) from a tank The pump discharges fuel to a rapidly pulsed, solenoid operated ball valve (20) which functions as a metering valve in controlling flow to the engine.  The solenoid (38) of the metering valve receives periodic voltage pulses of appropriate width from an electronic control which senses selected engine parameters and computes the required fuel flow and the pressure differential (Pr-PD) across the metering valve.  Since the pressure differential across the metering valve increases with engine speed, favorable flow turndown ratios may be achieved without operating the metering valve at high or low values of duty cycle.

Abstract: ABSTRACT:               A semiconductor laser having mirror faces serving as resonators, in which the active laser region comprises end zones adjoining the mirror faces and com-prise implanted ions, preferably protons, with associated crystal damage.  The end zones have a length which is at least equal to the diffusion length of the recombining charge carriers in the end zones.  As a result of the high recombination rate in the end zones substantially no non-radiating recombination occurs at the mirror faces so that mirror erosion is avoided. The invention also relates to a method in which the  end zones are formed by an ion bombardment on the upper sur-face of the semiconductor wafer with a number of lasers, which wafer at the area of the mirror (oleavage) faces to be formed is provided with grooves which do not extend up to the active layer, in which grooves the end zones are provided via an ion bombardment through the active layer.

Abstract: ABSTRACT         Novel compounds have been discovered in which a bis com-pound of a polysubstituted 2-keto-1,4-diazacycloalkane ("2KDZC") provides a diurethane bridge so as to form an oligomeric 2KDZC-urethane ("2K-U" oligomer) having from 2 to about 15 repeating units; the bis compound bridge itself consists essentially of two distally linked polysubstituted 2KDZC moieties, and the 2K-U oligomer formed consists essentially of two 2KDZC moieties linked through their N1 atoms, which moieties in turn are distally linked to urethane groups through the N  atoms of the 2KDZC. Such 2K-U oligomers unexpectedly contain a self-limiting number of 2K-U repeating units which happens to provide 2K-U oligomers which are desirable and highly effective u-v light stabilizers in organic materials; more specifically, this invention provides a novel class of polymeric hindered amine-urethane derivatives, particularly piperazinone bis compounds which may be distally linked to each other in a single step reaction utilizing an appropriately substituted diamine, a haloform such as bromoform or chlorform, in one of several known syntheses for making 2-keto-diazacycloalkanones, some of which syntheses may preferably utilize a phase transfer catalyst; this bis compound may then be hydroxyalkylated and reacted with an appropriate diisocyanate.

Abstract: ANTIGENIC MODIFICATION OF POLYPEPTIDES                 Abstract Modified polypeptides capable of provoking the formation of antibodies in an animal may be produced by forming a linear polymer of polypeptide fragments, each having a molecular structure similar to a fragment of the protein to which antibodies are to be provoked. Such linear polymers can be made more immunogenicthan the proteins to which they are related without introducing undesirable extraneous materials into the animal being treated, but have reproducable immunogenic properties. Proteins which are not endogenous or immunogenic to an animal can be chemically modified so as to make them more immunogenic. Also, modified antigens useful for fertility control can be produced by chemical modi-fication of zona pellucida or sperm antigens. These modified polypeptides, antigens and modified antigens are desirably administered in the form of a vaccine having a vehicle comprising a mixture of mannide monooleate with Squalene and/or Squalene.
