Title: Personal memory card system
Inventor: BERNSTEIN HOWARD L
IPC: G06K19/06
Filed: 1987-04-08
Granted: 1991-10-08
Abstract: Personal Memory Card System Abstract A personal memory card system is arranged for use with a memory card which looks and feels much like an ordinary credit card.  No ohmic electrical contact is required between the card and a reader/writer in an associated station for transferring data to and from the card and operating power to the card.  The need for conductive contacts in transferring data between the reader/writer and the card is avoided through use of a capacitive interface formed when insulated metallic plates on the card are aligned in close proximity with corresponding plates on the reader/writer.  Operating power is transferred to the card through an inductive interface formed when a flexible flat inductor embedded in the card is aligned in close proximity to another inductor in the reader/writer.  Data to and from the card and power to the card are reliably transferred even after some time of normal use since there are no exposed metallic surfaces to corrode or to which particles may collect.  In addition, the potential of damage to the card from electrostatic discharges is minimized since an insulator is provided between the electrical inputs to the card and any sources from which this discharge might occur.  The personal memory card system is also arranged to permit an authorized user to selectively reprogram a memory card with new and different data as desired.

Abstract: MULTILAYER PACKAGING FILM         ABSTRACT This invention relates to a co-extruded multilayer film and particularly for vacuum packaging food products. A vacuum packaging film is provided comprising at least two co-extruded layers, namely, a bonding layer comprised of a material selected from the group consisting of low-density polyethylene, high-density polyethylene, linear low-density polyethylene, ethylene-vinyl acetate copolymer with a vinyl acetate content of 3% to 9% by weight, ionomeric resins, and a mixture thereof; and a complementary layer comprised of an ethylene vinyl acetate-copolymer, wherein the vinyl acetate content is in the 15% to 26% range, by weight, the remainder being ethylene; said film being cross-linked by radiation.  The film is preferably radiated at a lower level than 20 MRad.  The film is adapted to resist high stretch ratios during the packaging process, so that packaging of bodies with projecting portions or cavities is possible, without breaking the film.

Title: Diffuser
Inventor: PRESZ WALTER M JR
IPC: B64C21/10
Filed: 1987-04-29
Granted: 1992-06-09
Abstract: Abstract A diffuser has a plurality of adjacent, adjoining, alternating U-shaped troughs and ridges which extend downstream over a portion of the diffuser surface defining an undulating surface portion of the diffuser wall.  The undulating surface delays or prevents streamwise two-dimensional boundary layer separation by providing three-dimensional relief for the low momentum boundary layer flow, thereby permitting diffusers to be designed with either greater area ratios for the same diffusing length, or shorter diffusing lengths for the same area ratio.

Abstract: TWIST ON ELECTRICAL CONNECTOR            ABSTRACT OF THE DISCLOSURE:            A    twist   on  electrical  connector   is   provided, comprising a moulded thermoplastic cap and a wire  coil insert therefore.  The cap is a thin walled  structure, and the coil is in substantially intimate contact along its entire length within the innermost,  wire retaining portion,  of the cap. A plurality of radially extending ribs, having substantial height and width, is formed on the outer periphery of the cap,  at least in the  upper portion thereof. The outwardly extending ribs provide a better finger grip, and are generally spaced apart such that  the  distance  between any two adjacent  ribs  is below  the 2-point  threshold of discrimination  for  a human  finger.  The ribs permit better heat dissipation from  the  interior of the cap,  in the event  of  heat build  up  therein;   and  the  generally  thin  walled construction permits easy injection moulding techniques with relatively quick mould cycle times.

Title: Interconnector device
Inventor: CHRISTOPULOS JOHN A
IPC: H01M50/253
Filed: 1987-06-30
Granted: 1991-03-05
Abstract: ABSTRACT OF THE DISCLOSURE         An interconnector device permits a lithium-sulfur-dioxide battery (e.g., the BA5847/U) to be substituted for a standard Leclanche battery (e.g., BA200/U).  The lithium-type battery can therefore be used in its customary manner or, with the interconnector, as a substitute for the Leclanche battery; battery proliferation is thereby reduced.  The interconnector comprises a rectangular wafer of plastic material with a pair of prongs mounted on one flat surface of the wafer and at a location which corresponds to that of female sockets of the lithium-type battery.          A pair of coil spring connectors are mounted on the opposite flat surface of the wafer and at locations which correspond to the locations of the coil spring connectors of the Leclanche battery.          The prongs and coil spring connectors of the interconnector are electrically interconnected in parallel.

Abstract: A deployment and retraction arrangement for a slot cover which is adapted to cover or seal a longitudinally extending slot or space present between at least two adjacent located membranes or panels.  More particularly, the arrangement is a rollable deployment and retraction arrangement for selectively deploying and retracting a slot cover employed for covering a slot or space present intermediate two adjacent membranes or panels so as to, preferably, prevent any FR leakage through the slot during radar operation of the panels.  The slot cover structure includes an elongated cover member consisting of upper and lower cover portions which are centrally fastened to each other along the longitudinal axis thereof, and with the cover portions being configured in transverse cross-section such that, in the extended deployed position of the slot cover, the upper and lower cover portions have clamshell configurations extending from the central axis, whereby the outer edges of the cover portions come into surface-engaging clamping contact with the surfaces of the applicable membrane or panel which is interposed therebetween, so as to be in essentially slot closing or sealing relationship therewith, and to thereby inhibit any FR leakage through the slot present between the panels, during radar operation. Additionally, suitable deploying and retracting operating structure is provided, which is in operative communication with the slot cover so as to impart a separating action to the lateral edges of the upper and lower cover portions upon initiation of deployment or retraction of the slot cover to thereby prevent any frictional contact between the edges of the slot cover portions and the facing surfaces of the respective panel or membrane which is interposed between the slot cover portions, and thereby minimizing any membrane distortion which could lead to deployment failure or membrane damage.
