Abstract: A PC card for insertion into a slot of a portable computer or other electronic device, has an antenna that allows the electronic device to send and receive data through radio waves. The antenna is moveable from a stowed position wherein most of the antenna lies in the PC card housing, and a first deployed position wherein most of the antenna projects rearwardly through an opening at the rear of the housing so radio waves can be transmitted and received. The antenna can be mounted on a tray that is moveable forwardly and rearwardly into and out of the rear of the housing. The tray can form a smart card-receiving recess that receives a small smart card to enable connection to pads on the smart card so as to provide authorization for communication through a wireless telephone network.

Abstract: A PC card of standard width and thickness (e.g. 54 mm and 5 mm) is constructed to receive a chip card of smaller width and thickness (e.g. 18 mm and 0.8 mm) so the PC card can used to connect contact pads of the chip card to an electronic device such as laptop computer into which the PC card is inserted. The PC card includes a sheet metal cover with a top cover portion (13) having a flat region that is deep drawn to form a ramp (30) that extends downwardly to an aperture (31). A chip card can be slid down along the ramp and through the aperture, and along an internal path portion in the card to engage contacts on a circuit board. Guides on opposite sides of the internal path portion can be formed by tabs (36, 37) partially punched out of the cover portion, parts fastened to the underside of the top sheet metal cover portion, and/or parts or components mounted on the circuit board.

Abstract: A PC card has an opening (24) in its upper sheet metal cover part for receiving a chip card (20), with a chip card guide (22) provided for guiding movement of an inserted chip card through the opening. The guide has a U-shaped upward projection (31) that lies in the opening against the rear and opposite sides of the opening. The guide has a ramp wall (32) lying under the opening to guide the leading edge of an inserted chip card. The guide is formed of a molded polymer with an upwardly-facing surface location (70) that is bonded facewise to the lower face of the sheet metal at a location immediately around the opening therein. The inserted card is stopped at a position where a portion of the chip card lies directly in the opening.

Abstract: An ammunition round for guns has a cartridge case provided with a detonator cap at one end, a bullet inserted in the other open end and an explosive charge between them. The base of the bullet has a recess in which there is a pyrotechnic insert generating an illuminated trace when the bullet is fired. The bullet may be an expanding bullet. The round provides a bullet with an integral trace device.

Abstract: Polyionic isotonic salt solution consisting of physiologically tolerable cations and anions and, optionally, colloids and a variety of substances known as additives to perfusion solutions, comprising .gtoreq. 80 mval/l potassium, .gtoreq. 1.7 mval/l of magnesium and, as anions, chloride, sulfate, phosphate and anions of organic aliphatic fatty acids or hydroxylic acids in a concentration of 90-160 mval/l in total, whereby the chloride ions are contained in physiological concentration of 100 mval/l at most.
