Abstract: A microstrip interconnector includes a ground plane layer, a dielectric layer coupled to the ground plane layer and a spring conductor, and provides a solderless connection between circuit boards. The spring conductor has first and second rising arms with a midsection therebetween. The midsection couples to the dielectric layer opposite the ground plane layer, defining a first elevation. First and second contacts proximate distal ends of the first and second arms, respectively, define at least one second elevation. The solderless interconnection is for example provided when the ground plane layer, the dielectric layer and the spring conductor cooperatively interact to provide a matched impedance path from the first contact, proximate a microstrip of a first circuit board, to the second contact, proximate a microstrip of a second circuit board that is separated from the first circuit board by a gap.

Abstract: A label dispenser includes a frame whose upper surface defines, in lateral cross-section, an arcuate trough within which to receive a supply of spiral-wound label-bearing linings or rolls. A pair of guide rods mounted on the frame in parallel-spaced relation to the trough's front edge guide the end of each lining first upwardly and then sharply downwardly so as to cause separation of individual labels from their respective linings upon movement of each lining relative to the guide rods. At least one spacer engages each guide rod at a like location intermediate the rod's ends so as to maintain the relative position of each guide during operation of the dispenser thereby to eliminate deleterious lateral deflection of one or more of the guide rods. Another rod is mounted on the frame in parallel-spaced relation to the trough's rear edge. Dividers slidably and pivotally supported by the rearward rod provide lateral support for the individual linings.
