Abstract: A method and a Bernoulli pick-up device for lifting and moving flat disc-shaped work pieces such as semiconductor wafers. The pick-up device has a working member the under side of which forms a flat suspension surface incorporating the orifice of a single inclined jet through which air is ejected in an unbalanced flow towards a limiting surface at one end of the suspension surface. In operation the working member is positioned over a wafer with the jet orifice separated a predetermined distance in front of the center of gravitation of the wafer whereby an initial drawing movement towards the limiting surface is impressed on the wafer. Wafers can be unloaded from a wafer magazine without any need of centering the suspension surface relative to the wafer. An improved magazine design makes it possible to unload wafers from arbitrary tracks independent of the presence of wafers in neighbor tracks.

In the locked position, the discharge latching lug will overlie the closing latching lug thus preventing removal of the closing member from the discharge member. Unlatching of the two members is achieved by a rotation of the closing member until the closing member latching lug is no longer underneath the discharge member closing lug. An indexing assembly can also be provided which will hold the unlocked position.

Abstract: The donning of surgical gloves is facilitated by inflating the surgical glove with the cuff open so that the surgeon may insert his hand into the glove while inflated and then deflating the glove around the surgeon's hand. The glove is mounted in a glove package with the cuff of the elastomeric surgeon's glove stretched around a ring. The ring with the glove so mounted is mounted at the mouth of a tube which telescopes into a larger tube making a sliding air seal with the larger tube. When the smaller tube is withdrawn from the larger tube, the reduced air pressure that results within the chamber defined by the tubes sucks the glove into the chamber and inflates it in the chamber. After the surgeon has inserted his hand into the inflated glove, the inner tube is then reinserted into the outer tube to increase the pressure within the chamber above atmospheric causing the cuff of the glove to explode off the ring on which it is mounted and snap around the surgeon's wrist.

Abstract: The method of joining the contiguous surfaces of telescoped end portions of tube members wherein at least one of the surfaces to be joined is coated with a layer of solder. A heated forming means is applied to the telescoped end portion to reflow the solder while simultaneously applying sufficient pressure in a radial direction to progressively reduce the radial clearance between the end portions in an axial direction toward the open end of the female member. The temperature and pressure applied is sufficient to provide melted solder between the surfaces to be joined as the crimping action proceeds axially so that excess solder is forced hydraulically out of the open end of the female member as the radial clearance is progressively reduced to a minimum. The scrubbing action of the molten solder as it is forced progressively from the radial clearance is effective in removing the oxide from the surfaces to be joined thereby completing a joint between the members.
