Abstract: CONTINUOUS METHOD OF AND APPARATUS FOR MAKING                BARS FROM POWDERED METAL               Abstract of the Disclosure Powdered metal is continuously introduced into a die cavity in discrete quantities and compacted into bar seg-ments to form a bar.  The cavity has a fixed cross-sectional area and is open at both ends, except during the initial compaction when one end is closed.  After formation of a length of the bar, the frictional resistance between the bar and the cavity wall is relied on so that the bar remain-ing the cavity serves as a stopper for subsequent compactions of the discrete quantities of powdered metal to form the continuous bar.  The bar is forced out of the cavity and may be passed through an induction furnace for sintering, and through a swager, all preferably in a continuous opera-tion.  Also provided is means for varying the compaction so that the bar lengths formed from the discrete quantities of powdered metal are compacted and bonded into a bar of substantially uniform physical characteristics along its length.

Abstract: ABSTRACT OF THE DISCLOSURE         The critical deformation of the shell of continuous steel castings is monitored and obviated by measuring bulging of the casting between at least two adjacent guide rollers located at the solidification zone of the casting.  By consider-ing the position of the guide rollers, the speed of casting travel and/or the quantity of coolant is adjusted to reduce bulging to or below an acceptable level.  The method is effected using guide rollers for detecting two reference points on the casting, and at least one pickup for detecting bulging between the guide rollers, a computer for receiving the bulge values and a control unit connected to the computer for varying the supply of coolant and/or the speed of travel of the casting.

Abstract: ABSTRACT OF THE DISCLOSURE          A transponder includes twelve directional filters that operate in both band stop and band pass modes.  The pass and stop bands of each filter has a center frequency that is substantially the same as the center frequency of one of twelve signal channels of the transponder, whereby each channel corresponds to a filter.  The twelve filters are connected to a rectangular waveguide at selected relative displacements from a downstream end thereof.  Signals within one of two groups of six alternate adjacent channels are propagated through their corresponding filters and through the downstream end without either an undesired signal loss or an undesired group delay.  Signals within five channels of the other group are propagated through their corresponding filters and through the downstream end with a symmetrical loss of the highest and lowest frequency portions thereof.

Abstract: Abstract of the Disclosure An exhaust manifold assembly for an internal combustion piston engine employs one exhaust tube for each cylinder and a collection chamber for each pair or larger group of exhaust tubes.  Each collection chamber is connected to a plurality of exhaust tubes so that the exhaust timing spacing is the same in each collection chamber.  The extended axes of the exhaust tubes connected to any one collection chamber intersect within that collect-ion chamber.  A single exhaust reaction chamber is fed from pipes carrying the discharge from each collection chamber, and the extended axes of the pipes intersect within the exhaust reaction chamber.  The effect is to reduce backpressure and to improve scavenging efficiency while maintaining relatively high exhaust gas temperature for purification efficiency.
