Abstract: A new host (14) and new PC card (12) are provided that have more than the standard two rows (16,18) of 34 contact positions each, where the new host can not only engage the new card but can also engage types I, II, and III standard PCMCIA cards so the new host is backward compatible to the large number of existing standard cards. The new PC card has the standard two rows (16,18) of 34 contact positions vertically spaced by 11/4 mm and has third and fourth additional rows (20,22) of card contact positions vertically spaced from the standard rows. The new card front end has laterally opposite card sides forming runners (44,48) of the standard thickness of about 3.3 mm, with the runners having upper and lower surfaces (72,74) lying respectively above and below the standard pair of rows, and with at least the third row lying above the level of the upper runner surfaces.

Abstract: An RF connector is provided for a PC card by having one element (40) of an RF connector in the host device into which the card is inserted. The card has a second element (30) of the RF connector. The two elements are arranged opposite each other when the card is fully inserted into the host device. In this way, a capacitive coupling can be provided between the respective circuits of the card and the host device. RF signals may, accordingly, be transmitted to and from the host device and the PC card.

Abstract: A new IC card is described, which can fit into standard card-receiving hosts that each has a host connector with 68 contact positions; however, the new IC card has more than 68 card contacts that can mate with more than 68 host connector contacts. The new IC card is designed to be inserted into a host stack of at least two vertically-spaced hosts. The new IC card includes upper and lower card connectors that each have 68 contact positions in accordance with PCMCIA specifications, and has a card frame that holds the two card connectors at a spacing equal to the vertical spacing of the host connectors. The card frame has slots on either side to receive mid walls that form parts of the host edge guideways, the card frame also including a slot at the front between the upper and lower card contacts to receive a separation wall of the host stack which separates the host connectors.

Abstract: An electronic device has a host with a card-receiving slot, with the host being capable of receiving and operating low voltage-low current (3.3 volts and no more than 0.12 amp) cards, low voltage-high current cards, high voltage (5 volts)--low current cards, and high voltage-high current cards. The inner end of the slot has a voltage-discriminating first side and an opposite current-discriminating second side. Each side has a switch with an actuator lying at a location that is occupied by a discrimination key portion that is present in one kind of card (low voltage or low current) but not in another kind of card (high voltage or high current). The electronic device has different circuits for energizing or rejecting the types of card sensed by the switches.

Abstract: An electronic device has a host with a card-receiving slot, and can receive and operate with both low voltage (3 volts) and high voltage (5 volts) IC (integrated circuit) cards. The inner end of the slot has a voltage-discriminating first side, and has a switch (82, FIG. 5) with an actuator (80) lying at a location that is occupied by a discrimination key portion (69) that is present in a low voltage card but not a high voltage card. The electronic device has both lower and higher voltage circuits (124, 130) for energizing lower and higher voltage cards, and the type of card sensed by the switch determines which circuit is connected to contacts at the inner end of the slot.

Abstract: A card-receiving host having a simple push latch/unlatch mechanism to aid in withdrawal of an inserted IC card. The host (24, FIG. 2) has dual push latch/unlatch mechanisms (54) which allows the card (16) to be fully inserted and latched when first pushed forward, and, after a second push on the card, unlatches the mechanisms and moves the card rearward by an amount predetermined by the latch implementation to facilitate grasping it to pull it out of the host. In one arrangement the host connector has a male pin assembly that is free to move in and out to accommodate the latch lost motion and to provide the means to transfer the latch spring pressure and motion to the IC card for its rearward travel. The host connector male pins are, in this implementation, terminated to the electronic device frame via a flexible cable (94), in another system (FIG.

Abstract: An adapter cable and card for interfacing a personal computer to a local area network or other type of computer network which can operate on either of two types of media. The cable uses a symmetrical plug connector which mates with a receptacle connector on the adapter card in either a first position, or a second position which is 180 degrees rotated from the first position. In the first position, signal lines for one type of media are connected and signal lines for the other type of media are disconnected. In the second position, signal lines for the second type of media are connected, and signal lines for the first type are disconnected. The disconnection of the unused conductors allows the drive circuits for unused type of media to remain active without causing electromagnetic interference problems.

Abstract: A catalyst for use in hydroformylation of olefins which comprises a Group VIII noble metal complexed with a phosphine ligand having at least one alkyl or aryl group bonded thereto, such as tris-4-propylphenyl phosphines and tris-4-octylphenyl phosphines. These and other triphenylphosphine catalysts can be separated from a crude reaction product of a noble metal-catalyzed hydroformylation reaction by contacting the crude reaction product with a dense polymeric, nonpolar membrane, preferably nonpolar polyolefin membranes.

Abstract: Basically, the present invention is predicated on the discovery that zeolites that have a high silica to alumina ratio, e.g., a ratio of 20 and above, pore diameters of greater than about 5.0.ANG., and which have substantially no active acid sites, i.e., zeolites which are non-reactive toward olefin isomerization and oligomerization, are especially useful in substantially separating linear olefins and paraffins from hydrocarbon mixtures containing at least linear and branched aliphatic hydrocarbons and optionally containing aromatic and other hydrocarbons.

Abstract: A method for selectively separating benzene from gasoline boiling range streams by first passing the stream to an adsorption zone comprised of an adsorbent capable of selectively adsorbing benzene from the stream. A substantially benzene-free stream results and the adsorbent is regenerated by treating it with a desorbent solvent capable of desorbing benzene from the solid adsorbent.

Abstract: In one embodiment of the present invention, there is provided an electrochemical cell having a metal bromine couple. The cell includes an electrode structure on which to deposit the metal of the couple and a counterelectrode at which to generate bromine. A microporous membrane separates the electrode and counterelectrode. Importantly, the aqueous electrolyte comprises an aqueous metal bromide solution containing a water soluble bromine complexing agent capable of forming a water immiscible complex with bromine and an additive capable of decreasing the wettability of the microporous separators employed in such cells by such water immiscible bromine complexes.

Abstract: It has now been discovered that reduction in the coulombic efficiency of metal halogen cells can be minimized if the microporous separator employed in such cells is selected from one which is preferably wet by the aqueous electrolyte and is not wet substantially by the cathodic halogen.

Abstract: The coulombic efficiency of aqueous zinc bromine batteries can be increased if, in addition to the bromide ions required to be present in the electrolyte to charge the cell to rated capacity, chloride ions are added to the electrolyte in amounts sufficient to reduce the amount of free bromine present in the electrolyte during operation of the cell.

Abstract: An electrochemical cell is described which contains, in a sealed configuration, an anode having a zinc anode-active material, a cathode having a halogen compound cathode-active material, a liquid electrolyte having a gas space above it, and an auxiliary electrode. The auxiliary electrode is made of a carbon-containing hydrophobic material, is adapted to carry a cathodic potential, and is positioned in the cell so as to be partially located in the liquid electrolyte and partially located in the gas space. A method of retarding pressure build-up in the cell also is described. The method involves converting hydrogen gas which is generated in the cell and builds up in the gas space to its ionic state via the formation of an ionic compound and dissolving the compound in the liquid electrolyte by creating a cathodic potential at the auxiliary electrode.
