Abstract: A concave surface for engaging and conforming to the convex side of a contact lens is provided together with partial vacuum generating structure operative to generate a slight degenerative partial vacuum at the concave surface to allow a pick up device upon which the concave surface is defined to be used to momentarily pick up and move a contact lens into close proximity to the cornea of an eye to which the contact lens is to be applied.

Abstract: A multipurpose workpiece holding device comprises a channel shaped frame adjustably mounted on a tilting and swiveling base. The frame has vertical slots on opposite sides thereof for adjustably receiving a lead screw on one side of the frame and a jaw forming element on the other side of the frame. The lead screw has a headed end for use as a clamp in conjunction with a concave jaw-forming element in the oppositely disposed slot and the device is also provided with an attachable and detachable vise jaw for the clamp element on the lead screw and a further vise jaw for use in place of the concave jaw element so that ready conversion as between a vise or clamp can be effected. Both single-jaw and double-jaw workpiece holding devices are disclosed.

Abstract: A rotary vise structure comprises a worktable journally mounted for rotation in a base member which includes a releasable latching rod adapted to engage selected openings in the worktable to hold the worktable in selected angular positions. The latching rod may be released to allow the worktable to be indexed to alternative angular positions, and the latching rod may also be held by a retainer in the released position to allow free rotation of the worktable. The worktable includes adjustable jaws for clamping articles thereon, the jaws being received in slideways of inverted-T profile. The worktable is made up of a plurality of plates secured face to face, the plates being appropriately slotted to define the inverted-T shaped slideways.

Abstract: A portable flashlight comprises an elongate battery casing and a swivelling flashlight head connected to one end of the casing through a ball-and-socket connection which forms part of the electrical circuit connecting the batteries to the flashlight bulb. A removable support pad is provided for attachment to an end cap of the casing for supporting the casing in vertical position while permitting swivelling movements of the flashlight head, and the casing further includes a transversely extending support pad for supporting the casing on its side and a magnetic assembly for magnetically attaching the casing to a support surface.
