Abstract: A lens case comprises an outer case member and a drawer with "left" and "right" contact lens wells slidable on the case member. Removable caps are friction fitted over each well, the caps also being hinged to the drawer. A foldout lid with a mirror is adapted for disposition over the caps. The arrangement is such that as the drawer is shifted to the closed position in the case member, a wall of the case applies pressure to the caps through the mirror or through tapered ribs on the caps to maintain the caps sealed on the wells.

Abstract: The subject invention conserves memory real estate by employing ROM cells which are FETs or non-FETs depending upon the programming. Each cell comprises a gate, a source and drain region and provision for connections to bit and word lines. Programming is achieved by a mask which permits doping of the source and drain regions to comprise FETs for the cells indicative of one state of logic while precluding doping of the source and drain regions to complete the channel in the cells comprising the other state of logic. Also, the FETs are fabricated, their contacts extending linearly between bit lines which are preferably diffused lines, and the word line making direct contact with gates of the linear cells. The process simplifies the number of steps required to manufacture the FETs and non-FETs by simply providing the programming after the basic cells are formed. Such unprogrammed structures may be inventoried and simply programmed i.e.

Abstract: A hanger assembly for use in a subterranean well incorporates a torque transmitting expansion joint providing a selectively adjustable extent of axial contraction. The expansion joint essentially comprises a telescopic inter-relationship of two sleeve assemblies. One sleeve assembly carries a fixedly mounted rectangular key which is engagable only with an axially extending slot provided in the other sleeve assembly. The first mentioned sleeve assembly also rotatably mounts a key which cooperates with a peripherally extending slot provided in the other sleeve assembly. The axial extending slot connects with a trough portion of the peripherally extending slot. Successive reciprocations of the two sleeve assemblies produce an incremental rotation of the round key around the peripherally extending slot and normally limits the extent of axial contraction of the two sleeve assemblies to the axial extent of such peripherally extending slot.
