Abstract: ABSTRACT OF THE DISCLOSURE         An AM stereo broadcasting system for transmitting stereo signals in the AM broadcasting band.  The system is based on amplitude modulation by two carriers having the same frequency and a 90° phase difference from each other, and is capable of increasing the modulation depth of pilot signals (used for stereo signal identification) irrespective of the stereo signals, so that the pilot signals can be easily detected.  By modulating both the sum and difference signals by the pilot signal, the receiver portion of the present system can derive the pilot signal irrespective of the stereo signals, thereby obviating many of the previous AM stereo broadcasting system problems.

Abstract: Abstract of the Disclosure The present invention relates to a process for producing acrolein and methacrolein by oxidation of propylene and isobutyl-ene or tertiary butanol in oxygen-containing gas mixtures on shell catalysts especially produced from an inert support and a shell encompassing said support.  The shell comprises an oxidic catalyst material containing the elements nickel, cobalt, iron, bismuth, phosphorus, molybdenum and tantalum or samarium and, when required, alkali or alkaline earth  metal, in specific atomic ratios.  This shell catalyst is obtained in a process in which a charge of the support moved mechanically by a gas stream injected from below while loosening it is sprayed from above in increasing amounts with a suspension of the starting material for the shell containing a binder and, when required, an expanding agent.  The ratio of dispersion sprayed on to the dispersion agent removed again by the gas stream remains approximately constant.  The coefficient of thermal expansion of the prestage as a dry powder must not differ from that of the support by more than 15%.  The shell is consolidated by further motion.  The material is dried in the gas, which continues to flow, and is tempered, when required, after decomposing any added expanding agent.

Abstract: ABSTRACT OF THE DISCLOSURE         A scan synchronized push-pull power supply for a television receiver has a source of direct voltage coupled to the primary winding of a power transformer.  A first controllable switch of the power supply includes a main current path and a control terminal for controlling conduction in the main path.  A second switch of the power supply includes a main current path with first and second terminals thereof.  The main paths of the two switches are coupled to the primary winding in a push-pull arrangement.  A deflection rate signal that is synchronized with scanning current generation is applied to the control terminal of the first switch to alternately switch conduction of its main current path between conductive and nonconductive states during each deflection cycle in synchronism with the scanning current generation.  The switching of the main current path of the first switch to either the conductive or nonconductive state produces a change of voltage between two main path terminals of the second switch so as to switch the conduction state of the second switch to the one that is opposite that of the first switch.  The switching action of the two switches results in the development of alternating polarity voltages across the primary and secondary windings of the power transformer.

Abstract: ABSTRACT OF THE DISCLOSURE           A sine-function generator comprising a plurality of bipolar transistors with their collectors connected to a pair of output terminals in alternating antiphase and their emitters connected in common to a single current source.  The bases of the transistors are connected to respective nodal points of a base-bias network comprising a series-connected string of equal resistors.  Current sources supply equal currents to the network nodal points to develop base voltages at those points according to a predetermined distribution pattern establishing a peak voltage along a line representing the nodal sequence.  An input signal applied to the ends of the resistor string controls the location of this voltage peak along the nodal line, thereby controlling the current flow through the transistors in such a way that the net differential output current is proportional to the sine of the angle represented by the input signal.  A ladder-type base-bias network also is disclosed.

Abstract: Abstract of the Disclosure High density, generally microscopically homogeneous corrosion-resistant chromium-uranium metal alloys for ammunition use (particularly for spherical pellets or shot) can be made from U238 or an isotopic mixture high in U238 (such as "depleted uranium") and at least about 10 atomic % chromium.  The alloys can also contain one or more metals of Group VIII, first triad, of the Periodic Table, and a variety of other elements used, for example, in making ferrous metals.  Major factors to be considered in formulating  the alloy are densi-ty, melting point or melting range, passivity or chemical or biological inertness, resistance to segregation in the molten phase and upon rapid cooling (chromium-poor phases or regions being particularly undesirable), and compensation for any loss of free chromium due to formation of intermetallic or other forms of combined chromium.  The uranium content in the alloy is preferably less than 70 atomic %.  Rapid cooling of the chromium-uranium or chromium-uranium-Group VIII metal melt, e.g. by the shot tower technique, avoids undesirable segregation effects which can detract from corrosion resistance. The shot tower may optionally contain a non-oxidizing atmosphere.

Abstract: Abstract In a process for producing wooden building components acted upon by flexural forces in the built-in condition, and made up of at least two members that are bonded together, the load capacity is increased by stressing at least one part of the component in the direction of its length by a linear force and is then bonded to another part of the component while still being acted upon by said force. In a preferred form of the invention at least one part of the component is acted upon by a pulling force and another part is acted upon by a compression force with a pre-stressing effect. The use of the process makes possible the production of bonded wooden structural members free of transverse forces.
