Abstract: Abstract The  present  invention  is  directed  to  muffler apparatus and a method for making same.  The apparatus inclu-des  inlet  and  outlet  tubes  with  a  plurality  of  baffles extending from the inlet and outlet tubes to a housing.  The outlet  tube  has  a constricted  portion  near  its  inlet end formed with creases and lobes and a flare at the end.  Such constriction increases the housing to outlet tube area ratio of  the  muffler  which  results  in  advantageous  attenuation characteristics.    The  process  for  making  the  muffler  is simpler than known methods since the outlet tube is formed and baffles pressed onto it in a single step.

Abstract: ABSTRACT OF THE DISCLOSURE     An automatically adjusting automobile parking brake actuating mechanism has a thrust screw attached to a fric-tion pad and axially translated in response to normal brake activating movement of the friction pad.  An adjusting nut having an axial threaded bore threadingly receives the thrust screw and includes coaxial ratchet teeth and a peri-pheral groove externally circumscribing the adjusting nut. An adjuster pawl having a pivot, an adjusting leg communica-ting with the ratchet teeth and a camming leg communicating with the peripheral groove effects pivotal movement of the adjuster pawl, thereby causing rotation of the ratchet teeth and the adjusting nut relative to the thrust screw.  An axial force is applied upon the adjusting nut to effect axial translation of the adjusting nut and the thrust screw to urge the friction pad into a brake applying mode.

Abstract: Abstract of the Disclosure Mixtures of di-tert-octyldiazene (where tert-octyl refers to 1, 1, 3, 3-tetramethylbutyl) and tert-octyl secondary or primary alkyl diazenes are prepared by reacting mixtures of tert-octylamine and a primary or secondary alkyl primary amine with sulfuryl chloride and oxidizing the resultant mixture of sulfamides with basic bleach.  Then, the mixture of diazenes is heated in a chlorinated solvent and the di-tert-octyldiazene decomposes and the unsymmetrical tert-octyldiazene rearranges to a tert-octylhydrazone.  The tert-octylhydrazone is extracted out of the solvent with dilute acid, the acid solution extract is heated to 40-50°C, and the ketone that forms is stripped off under reduced pressure.  The acid solution is neutralized to form tert-octylhydrazine.  The tert-octylhydrazine is an intermediate that can be reacted with various compounds, e.g., ketones, aldehydes, acids, acid chlorides, isocyanates, chloroformates and sulfonyl chlorides to form different t-octylhydrazine derivatives.

ABSTRACT OF THE DISCLOSURE           A battery charging system is provided including a charger and a rechargeable battery of "standard" size and configuration.  The rechargeable battery bears a special indicia that is sensed by the charger as a precondition to enabling the charging circuit of the charger.  The indica-bearing battery can thus be used in place of "standard" non-rechargeable batteries in battery using products of various sorts, but non-rechargeable batteries, lacking the special indicia, cannot be charged in the charger.  Potential damage to the charger or product and other adverse effects associated with charging of non-rechargeable batteries is thus avoided.

Abstract: ROLL FOR USE IN CALENDERS AND THE LIKE             ABSTRACT OF THE DISCLOSURE           A roll for use in a calender has a stationary carrier which is surrounded by a hollow cylindrical shell with the interposition of a hydraulically operated displacing unit which can flex selected portions of the shell when necessary so as to establish a preselected nip between the peripheral surface of the shell and the shell of an adjoining roll.  The hydrostatic displacing unit is flanked by two antifriction bearings which operate between the carrier and the shell and are lubricated by a circuit which is independent of the circuit that supplies hydraulic fluid to the displacing unit.  This renders it possible to use in the displacing unit a fluid whose temperature is much higher than the maximum permissible temperature of lubricant for the bearings.  The bearings are sealed from the respective ends of the displacing unit by single seals or by multiple seals, and any leak fluid which penetrates beyond the neighboring seal is evacuated through one or more channels in the carrier and/or in the shell.  Lubricant for the bearings may but need not be identical with hydraulic fluid which is supplied to the displacing unit.

Abstract: METHOD OF OPTIMIZING FLOW PATTERN AND INCREASING    SIGNAL-TO-NOISE RATIOS IN ELECTROCHEMICAL           FLOW THROUGH SENSORS    ABSTRACT In electrochemical flow through sensors comprising at least one cell for the passage of a fluid for analysis therethrough, the method of optimizing the flow pattern and signal-to-noise ratio comprising the steps of loading the cell under high pressure with a first fluid which will set to a solid material; before the solid material solidifies, causing a second fluid immiscible with the first fluid to flow through the cell at low pressure to find the optimum flow path therethrough; and, with the immiscible fluid in the cell, allowing the first fluid to  solidify. Bandspreading is improved because any offset, junctions, or potential traps that would induce drag or trapping effects on a test fluid flowing through the cell are reduced in size and/or number and/or eliminated.  The signal-to-noise is improved as the result of filling spaces in the cell that may contribute to noise but do not contribute significantly to useful signal because of their location relative to the optimum flow path.
