Abstract: TITLE                 DIFFERENTIAL THERMAL WATTMETER                              INVENTORS                          Louis G. Cox Norbert L. Kusters ABSTRACT OF DISCLOSURE                The differential thermal wattmeter for the ac/dc transfer of power includes a differential thermal con-verter as a "sum and difference" multiplier, with both ac and dc voltage and current signals simultaneously applied to both heaters. DC feedback to the current input speeds up the response and maintains thermal balance between the heaters, so that the output meter becomes a null indicator,  This reduces and can eliminate the need for quadratic response.          The requirement for exact matching of the thermal converters is also eliminated by effective interchange of the heaters.

Abstract: ABSTRACT OF THE DISCLOSURE         A container (pod) is disclosed for photographic processing liquid which contains an aromatic alcohol in which a cavity-forming layer is provided for a strong seal at the edge areas of the container (2 to 3 lbs./in.).  However, in selected edge areas of the cavity-forming layer an additional adhesive layer is located which provides for a more easily bursting seal.  This differentially weaker seal/stronger seal effect is accomplished by the use of an adhesive layer comprising a a) crosslinked homopolymer of 2-acetoacetoxyethyl methacrylate or a crosslinked copolymer of this compound with specific norbornyl esters of methacrylic acid or b) crosslinked homopolymer of specific norbornene esters of methacrylic acid.          The cohesive strength of such a polymerized and cross-linked composition is such that it permits the bursting of the adhesive layer at a desired level of pressure (0.3 to 0.7 ??./in.).

Abstract: 2195-7a ABSTRACT OF THE DISCLOSURE     A machine which converts a strand of wire into a body of meandering shape has two carriers which rotate about parallel axes and respectively carry annuli of pins.  One annulus of pins surrounds the other annulus of pins, and each pin of one annulus is adjacent to a pin of the other annulus.  When the carriers rotate, neighboring pins of the two annuli move toward each other during one-half of each orbital movement about the respective axes and away from each other during the other half of each orbital movement.  A looping device winds the wire alternately about the oncoming pins of the inner and outer annuli while the neighboring pins move away from each other whereby the wire is converted into a meandering body and the wire portions between successive pins are stretched to assume a predetermined shape.  The meandering body is stripped off the pins while the neighboring pins move nearer to each other.  The meandering body can be used as a starting material for binders which connect the sheets of note books, calendars or the like.
