Abstract: Abstract of the Disclosure A substantial reduction of free excess formaldehyde in formaldehyde laden wood panels is achieved by coating at least one side of the panel with a salt solution containing an ammonium cation such as a 10-15% aqueous solution of ammonium bicarbonate.    After coating, a barrier is placed over the coated surface such as by stacking a plurality of similarly coated panels with the barrier being maintained sufficiently long to allow ammonia gas generated from normal degradation of the ammonium salt to migrate to the free formaldehyde zone where the ammonia gas reacts with the formaldehyde to produce a stable, low volatility reaction product.  The treatment may be applied to raw or finished panels and the generated ammonia gas reacts in the stacked panels with formaldehyde in both the glue lines and the formaldehyde based finish topcoating.

Abstract: Title CLUTCH LEVER AND ADJUSTMENT METHOD           Abstract of the Disclosure A method is disclosed for constructing and adjusting a plurality of release levers of a friction disc clutch.  The method ensures that the inner or nose ends of the release levers lie in a common plane upon final clutch assembly.  In a preferred embodiment, a rivet is secured to the nose end of each release lever.  The resulting lever unit is heat treated in a manner wherein the attached rivet is hardened throughout its entirety, while the lever per se is case hardened to a specified depth.        Next, a clutch cover, pressure plate, pressure means for urging the plate, and the plurality of heat treated lever units are installed together to form a clutch cover sub-assembly.  Relative movement between the clutch cover and pressure plate is effected against the bias of the pressure means until the levers are in an extreme position relative to the clutch cover.  The rivets are then machined, preferably by a grooved grinding wheel having a suitable contour in order to adjust the nose ends of the levers to a pre-determined common plane.        Alternatively, the heat treatment step may be limited to the rivet per se, wherein the rivet may be heat treated after the machining step.

Abstract: ABSTRACT           A  method for production of a multi-layer gap-less steel pipe.  An inner pipe and an outer pipe are formed from thermomechanically rolled steel strip with high notched  bar impact  strength by welding.  The individual helical welding seam steel pipes of about the same lengths are matched  with a  difference  of  less than about one percent  between  the outer  diameter of the inner pipe and the inner diameter  of the outer pipe.  The matched inner pipe is inserted into the outer  pipe  and the pipes are  mechanically  expanded  with length control to a preset outer diameter of the multi-layer steel  pipe.  The  resulting multi-layer steel pipe has  the inner  pipe  disposed under compression and the  outer  pipe layer disposed under stress.  The presence of a  compression stess  in the inner pipe provides a means opposed to  stress corrosion.  The advantages of the helical welding seam steel pipes    can  be  combined  such  as  economic   production, advantages relating to crack formation and crack propagation stopping,  and  the availability of high internal  pressure loads  upon use of thin ,  economic steel strip of different yield strength.

Abstract: ABSTRACT A transistorized microwave oscillator comprises an oscillator circuit including a transistor and a feedback capacitor.  The oscillator circuit generates a fundamental oscillating frequency and harmonic components.  A cut-off waveguide is connected to the oscillator circuit for cutting off the funda-mental oscillating frequency and unwanted lower-order harmonics to provide a higher-order harmonic.  According to the invention the feedback capacitor is utilized as the coupling circuit for extracting the desired harmonic from the oscillator circuit.  Also, the feedback capacitor is concurrently used as an antenna.  The nth harmonic of the fundamental frequency radiated from the antenna is extracted into another circuit through the cutoff waveguide.  Since the waveguide and oscillator circuit are interconnected merely by the wave-guide, which has a width determining cutoff, the complexly structured fre-quency multiplier coupling antenna of the prior art is not necessary.  Also, as the oscillator circuit can readily be incorporated with the waveguide by a solid piece of metal, the structure and manufacture are simplified.
