Abstract: A D H E S I V E   B O N D I N G   O F     A L U M I N U M   C O I L S     ABSTRACT OF THE DISCLOSURE    The present invention is directed to a method and apparatus for joining aluminum members within an aluminum heat exchanger coil.          A tubular member to be joined to a separate member in the coil has its exterior surface roughened by sand blasting to enhance adhesive adherence.  The roughened surface is covered with a conversion coating to replace any accumulated aluminum oxide, to prevent the formation of additional aluminum oxides and to simultaneously provide a surface adapted to adhere to an adhesive.  An adhesive is then applied to the mating areas of the tubular members to be joined and subsequently cured to form a tight secure joint.  This invention is particularly useful in field repair of aluminum heat exchanger coils.

Abstract: ABSTRACT OF THE DISCLOSURE           An improved apparatus for successively separating and feeding sheets from a stack of sheets is disclosed.  A wave generator wheel, rotating in a plane generally parallel to the stack, and about a tiltable axis generally perpendicular to the stack, is tiltable in a first direction to contact the stack for shingling the stack, and in a second direction to the contact the stack for restoring the stack to its un-shingled state.  Sheets in a stack are driven forward or rearward by simply tilting the rotating wheel.  The wave generator wheel is controlled by an open-loop or closed-loop control arrangement to first drive the stack's top sheet away from a feed nip, and to then drive the stack's top sheet into the feed nip.  Instead of tilting the wheel, the wheel can be in the form of rollers connected to a disk via flexible spokes which are depressed to contact and drive the stack's top sheet.

Abstract: "HYDRAULIC IMPACT DEVICE" Inventor - Edgar J. Justus ABSTRACT OF THE DISCLOSURE             A hydraulic impact device in which a hammer member having a piston portion is reciprocally disposed in a cylinder, a reciprocating sleeve valve is disposed within the cylinder and surrounds the hammer member.  The sleeve valve has a first peripheral seal with an upper portion of the cylinder and a second peripheral seal with the lower portion of the cylinder so that an annular cavity is formed between the first and the second peripheral seals.  The bottom portion of the sleeve valve forms a single seal with the upper portion of the piston section.          A pressure relief valve is situated between the inlet to said annular cavity and an annular cavity below the piston portion to insure that the pressure in said annular cavity is greater than the pressure in the cavity below the piston portion and the sleeve valve thus effecting a sealing force between the sleeve valve and the upper face of the piston portion. An energy storage means is provided for receiving energy from said ram member during its upward stroke.  The upper and lower sealing portions of said sleeve valve are axially spaced such that when said lower sealing portion seals a fluid inlet port, the upper sealing portion opens a fluid outlet port thereby reducing the pressure in said annular cavity by interrupting a fluid communication between the inlet port and said annular cavity and establishing fluid communication between the outlet port and said annular cavity.

Abstract: ABSTRACT OF THE DISCLOSURE           An apparatus for inductively heating cooking utensils comprising four induction cooking coils excited by a central power oscillator providing an alternating sinusoidal excitation voltage at about 25 kilohertz which is 100% amplitude modulated at 120 hertz.     Power to the four induction coils is duty cycle controlled by four 60 hertz triacs each series inserted between the power oscillator and a respective one of the induction coils.  The triacs switch to excite their respective induction coils only at the zero point of the excitation voltage modulation envelope.  Line power fluctuations are minimized by sequential switching of the triacs in a manner that results in an effective power switching frequency of approximately 46 hertz when all four induction cooking coils are excited.  The central power oscillator is inherently protected from high Q load conditions without the provision of feedback loops.
