Abstract: ABSTRACT       A fixture for locating the conductors of a multi-conductor flat, flexible cable relative to a multi-contact electrical connector prior to the simultaneous connection of each contact to an individual conductor of the cable includes a clamping bar having a surface adapted to extend across the width of the cable.  Side-by-side parallel flutes extend across the surface the flutes being spaced apart a predetermined distance on centre lines which extend normally of the surface.  Each flute has a centre of curvature and the centres of curvature of alternate flutes are offset with respect to the centres of curvature of the remaining flutes.  When the clamping bar co-operates with a support surface of the fixture to clamp the cable to the support surface, the conductors of the cable assume a zig-zag array as seen in transverse cross-section.  The clamping bar and the support surface form part of a cable support which is attached to but capable of limited move-ment towards and away from a surface of a connector support. When pressure is applied to the cable support a cable will be moved relatively-towards the surface of the electrical connector from which extend a plurality of electrical contacts.  Conductor receiving portions of the contacts penetrate simultaneously and cable and establish electrical contact with the conductors.

Abstract: Abstract of the Disclosure A phase compatible polymer blend serves as a radiation sensitive lithographic resist in the fabrication of circuits and circuit elements.  Radiation sensitivity is due to inclusion of a "modifier".  Resist properties, notably stability to agents and ambients to be masked are attributed largely to a second component, the "matrix polymer".      In an exemplary embodiment in which the blend is positive acting, fabrication including dry processing is dependent upon use of a resist blend of a vapor developing polysulfone and a novolac.  The novolac, inherently soluble in alkaline media is rendered insoluble in the blend.  Radiation initiated depolymerization results in volatilization of the modifier to render the irradiated portions of the resist soluble in alkaline developers.      Modifier may function in other manner; for example, it may undergo radiation initiated polymerization so as to insolubilize the blend in irradiated regions, so resulting in a negative acting resist. Effective isolation of lithographic from masking functions permit  design of blends with high lithographic sensitivity, as well as good processing stability.  The latter is sufficient to permit use in many dry processing procedures as practiced in direct writing, as well as in mask fabrication of large scale integrated silicon circuits.

Abstract: APPLICATION OF:  DONALD M. BERLIN, JR.   FOR:  CALIBRATION MECHANISM FOR A PRESSURE SWITCH                   A B S T R A C T    A calibration mechanism for a pressure switch of the type utilizing a rotary cam which controls the setting of a spring-biased plunger to establish pressure levels re-quired to actuate the switch.  The calibration mechanism includes a support bracket mounted on the switch and a cam assembly including an integrally formed cam member and cam-shaft.  A plunger adjustment mechanism includes a pivotally mounted lever having a cam follower in following engagement with the cam. The support bracket defines a bore adapted to receive the camshaft.  The cam has a range of rotational orientations in which the cam follower engages the operative portion of the cam profile.  The camshaft includes a pro-jection extending radially therefrom which is axially dis-posed from the cam a predetermined distance greater than the axial length of the bore in the support bracket.  The support bracket defines a slot extending from the bore.  The cam assembly is assembled to the support bracket by orient-ing the cam assembly relative to the bracket such that the projection on the camshaft passes through the slot as the camshaft is inserted in the bore.  The cam assembly is then rotated to the operable range of angular displacement in which the projection is angularly offset from the slot, thus axially retaining the shaft of the cam assembly in the bore of the support bracket.

Abstract: Abstract of the Disclosure A heated metal plate drying system for drying either green veneer or partially dried veneer can have a plurality of modular hot presses mounted on a frame. At a loading station, individual sheets of veneer to be dried or redried are fed into a hot press, and at an unloading station the dried veneer sheets are unloaded from the system. Within each individual modular hot press, a direct contact drying process occurs that functions to reduce the moisture content of a veneer sheet down to the desired uniform level such as within a range of from 1 to 10%. The drying process accepts veneer of different species, thickness, and beginning moisture contents and the controlled process variables include contact time, temperature and pressure. Each individual modular press can be multi-opening and has the ability to open and close on command. Specially designed heated metal plates are part of each press and each plate has substantially parallel grooves on at least one surface. The modular presses are mounted on the frame such that they may be tilted at the unloading station to facilitate unloading of the dried veneer sheets. At the loading station, a loading apparatus functions to sequentially feed individual veneer sheets into the openings. The loading apparatus is pivotally mounted. Also provided is an aligning apparatus for ensuring proper alignment of each veneer sheet within its respective opening after being loaded. The modular presses in one embodiment are mounted on a carousel frame structure that is rotatable on a main bearing so each modular press indexes past the loading and unloading stations.
