Abstract: ABSTRACT           This invention relates to an improved bottom block for vertical DC and EM casting large ingots and billets, particularly ingots having generally rectangularly shaped cross sections which are rolled into sheet and plate.  The improved bottom block stably supports the ingot or billet in its downward descent during casting so that the ingot or billet does not move on the bottom block by leaning off center or rocking back and forth.  In accordance with the invention, a plurality of drain holes in the bottom block, which are adapted to remote coolant which collects on the top surface of the bottom block, are provided with fan shaped recesses which form appendages on the butt of the ingot or billet.          These ingot or billet appendages ride up the lower inclined surfaces of the recesses when the ingot or billet butt shrinks and curls, thereby stabilizing the ingot or billet.

Abstract: Method and Apparatus for Making Tubes Formed with Holes in their Peripheral Wall Abstract of the Disclosure The invention relates to a method for making tubes formed with holes  in  their  peripheral  wall, particularly muffler tubes,  in which the tubes are formed of sheet metal and subsequently  welded along  abutting edges  of the sheet metal.   Known from practical application is a method of the type defined above, in which  a  hole  pattern  is initially punched  into  a  sheet  metal  strip.    The metal strip is subsequently formed, as by a roll forming method, into tubes which are  then closed  by a  longitudinal weld seam.  After the welding step the tubes are cut to length by  means of a cutting  device,   the  operation  of  which  is  controlled depending on the hole pattern.   It  is  the  object  of the invention  to  provide  a  method  and apparatus of the type defined  above  which  in  addition  to   the  advantage  of economical production  offers the possibility of forming the tubes with holes over their entire  periphery.   With regard to  the  method  according  to the invention, this object is attained  by  introducing  a backing   element   into  the previously welded  tube and  forcing it into engagement with the interior wall surface thereof, followed by the formation of holes from the exterior in the area of the tube supported by the backing element.

Abstract: ABSTRACT A multi-channel laser ROS scanner for simultaneously scanning laser beam components across multiple lines of a photosensitive surface including appratus for determining deviations in the position of the surface from a desired position due to undesired photosensitive surface velocity variations whereby an error correction signal can be generated, and a TIR modulator having a plurality of interdigitated, addressable drive electrodes. The total number of drive electrodes Nt of the TIR modulator is greater than the collective number of drive electrodes Ns needed to provide the desired pixel resolution for all of the simultaneously scanned lines. When the photosensitive surface is maintained at a desired velocity, such velocity being determined in a conventional manner by system parameters, the surface is correctly positioned and Ns adjacent drive electrodes located generally centrally within the TIR electrode configuration are addressed by the video data signals for the multiple scan lines, causing the laser beam components to exit the TIR modulator with an unshifted or "normal" propagation direction within the optical window of the modulator resulting in scan lines being recorded at desired positions on the photoreceptive surface. Should the photosensitive surface deviate from its desired position at a given time, the error signal functions to cause Ns different adjacent drive electrodes to be addressed whereby the laser beam components exiting the TIR modulator are shifted in propagation direction such that they strike the photosensitive surface at a placement which corrects for the position deviation.

Abstract: ABSTRACT         An automatic linear compression circuit for a telephone "handsfree" loudspeaker is provided.  The circuit consists of a variable attenuator the level of attenuation of which is controlled by the input signal level.  The input signal is passed through a positive peak detector to obtain a time averaged signal corresponding to the average positive peak values of the input signal and this time averaged signal is compared against a time increasing reference voltage.  As long as the reference voltage is below the value of the time averaged signal a positive attenuator control signal is derived.  This positive control signal keeps the attenuator portion of the circuit operative.  In the attenuator the input voltage is sampled to a first capacitor.  The first capacitor is subsequently connected to and disconnected from a second capacitor a number of times as long as the positive attenu-ator control signal is present.  Each time this is done the voltage on the first capacitor is reduced by a factor depending on the capacitances of the two capacitors. After a predetermined time the voltage remaining on the first capacitor is passed through buffers and another capacitor to provide an attenuated output.  The circuit is simple and flexible, permitting wide ranges in the operating parameters to be achieved simply by including one or more variable capacitors.
