Abstract: Heat-sealable laminates useful as packaging materials, for example, for the packaging of photographic processing chemicals, are comprised of a metal foil, a thermoplastic polymeric film, and an interlayer formed by radiation curing of a composition comprising an acrylated epoxy resin. The laminates are manufactured by a process which comprises forming a sandwich comprising a layer of metal foil, a layer of thermoplastic polymer and an interlayer formed from a composition comprising an acrylated epoxy resin and irradiating the interlayer through the layer of thermoplastic polymer, for example by the use of ultraviolet radiation or high energy ionizing radiation, to cure the interlayer and bond it to both the layer of metal foil and the layer of thermoplastic polymer.

Abstract: A high level of aromatics are absorbed by coffee oil by placing a coffee aroma frost in an isolated vessel, raising the internal temperature and pressure, removing water from the pressurized vessel and thereafter introducing coffee oil into the pressurized vessel. The mixture is allowed to equilibrate for a period of time and is then slowly vented.

Abstract: A circuit board connector having a plurality of pairs of contacts arranged in a row and with each contact having a "C" shaped portion. Each pair of contacts is mounted securely at first ends thereof in a circuit board with the backs, or closed sides, of the "C" shaped portion facing each other and designed to receive the edge of a second circuit board inserted therebetween. The free end of each contact has an ear-like element extending outwardly from the board to which the contacts are secured. A connector housing fits over the pairs of contacts after they have been secured in the board. Inside the housing tabs are provided, behind which tabs the ears of the contacts are positioned, thereby prestressing each pair of contacts apart. The housing is also designed so that the side walls thereof press against a dimple or finger-like tang formed near the base of each contact, thereby forcing the contacts of each pair of contacts together and further enhancing the prestressing of each pair of contacts.

Abstract: A printed circuit board connector is comprised of an elongated rectangular housing having a passageway in a longitudinal edge thereof for insertion of the board. A thin plate lever lying along the outer surface of each side wall of the housing and rockably mounted thereon, is provided at its free end with openings to capture the free ends of resilient contact members supported within the housing for retracting them against their bias from the path of a circuit board inserted in the passageway. A thin slidable cam plate between each of the side walls and plate levers cooperates with projections on the walls for causing them to move outward for pulling the contacts away from the passageway. A feature of the invention is that the housing and plate levers are all injection molded in one piece, and the levers are broken off the housing and rockably mounted thereon.

Abstract: Soluble coffee of improved stability during storage is prepared by removing a portion of the aromatics from an aqueous coffee extract, drying the remaining extract, fixing the removed aromatics by mixing them in solution with a fixative and drying the resultant solution, and adding at least a portion of the fixed aromatics to the dried remaining extract. The soluble coffee powder so prepared is characterized by its lack of off-flavors normally developed during storage.

Abstract: A metal clip for connecting an insulated wire and a terminal post together without stripping the wire or solder. The clip is generally channel-shaped with a first slot means extending across the bottom wall of the channel and into the side walls of the channel. Extensions of the free end of the side walls are folded within the channel back towards the bottom wall and have second slots formed therein which are aligned with the first slot means. The conductor is inserted into the first and second slots and then the terminal post is pushed into the channel at right angles to the wire and adjacent the bottom wall thereof to force the conductor farther back into the slots and causing the edges of the slots to either grip or cut through the insulation and into the wire, thereby making a good electrical and mechanical connection.

Abstract: An electrical connector for a substrate including a housing having a base, an elongated channel and a plurality of cantilever contacts mounted in the base extending into the channel, and a member operatively mounted in the channel having a base including an aperture receiving each contact mounted in the base of the insulating housing. Inter-engaging latch arms on the housing and member provide for zero insertion force loading of the substrate in the member in a loading position. A cam surface in each aperture cams each contact into engagement with a conductive pad on the substrate and provides a wiped, graduated force electrical connection when the substrate and member are operatively engaged in the housing in a loaded position and the substrate, member and housing are secured by the inter-engaging latch arms on the member and housing.

Abstract: A female contact particularly useful as a low profile contact inserted in a printed circuit board and comprising a tubular portion with a flared open end for receiving a male pin. A pair of opposing contact fingers extend from the flared open end and are folded back upon themselves to extend downwardly into the interior of the tubular portion. Near the open end of the tubular portion the two opposing fingers are initially close to, and substantially parallel to, the walls of the tubular portion. As they extend further into the tubular portion, the curved fingers extend away from the walls of the tubular portion and towards each other, with their concave surfaces facing each other. As a terminal post is initially inserted between the fingers the fingers are deflected apart and outwardly towards the walls of the tubular portion so that a point on said fingers will be forced against the wall of the tubular portion.

Abstract: An electrical connector for a flat multi-conductor transmission cable includes a cable terminating face, a parapet having a plurality of V-shaped grooves and a scalloped top extending from the face, a bus strip engageable with the face, and a cover. Also, a method for terminating the cable includes severing an insulated sheath of the cable intermediate its end, sliding the severed insulated end along a length of the conductors to expose the shield and signal conductors, severing the signal conductors, folding the insulated end of the transmission cable back along its length over a bus strip, and engaging the shield conductors with the bus and the signal conductors with electrical terminals on the face of the connector.

Abstract: An electrical connector for forming a high amperage connection with a male pin includes a number of beams surrounding the pin and a collar surrounding the beams. The end of the pin is inserted into the connector and moved past outer contacts on the beams and engages inner contacts on the beams to force the inner contacts radially apart and rock the beams about the inner surface of the collar to force the outer contacts against the pin. Alternate inner contacts are axially spaced to reduce the insertion force.

Abstract: An apparatus consisting of a pair of rollers with tangentially meeting perimeters for crimping successive portions of a continuous strip of solder into rings around a strip of terminal posts carried in parallel manner upon a common carrier strip. The roller perimeters each contain a circumferential track of crimping ridges which are both axially and angularly positioned to coincide with corresponding ridges on the other roller to crimp said solder strip around each post on the strip of terminal posts, both strips being simultaneously passed between the crimping tracks on said rollers. Each roller also comprises a circumferential track of spur-type gear teeth, the two tracks being axially offset on opposite sides of said crimping tracks and having bottom lands (the troughs of the teeth) which coincide when the teeth pass through the common tangential or pitch plane of the rollers.

Abstract: According to one aspect of the disclosure, a planar substrate receives a plurality of conductive posts therein, which posts include an offset medial portion having a laterally projecting notch portion. Certain posts are arranged with their notch portions in coplanar relationship and in latching registration with an interior sidewall portion of a housing received over the posts. Accordingly, the housing provides an insulating receptacle shroud for the posts and is latchingly retained in place without a need for attachment to the substrate. The shroud is also provided with card guides connected thereto by integral hinge portions enabling alignment of, and reducing twisting and warping of, the card guides. The card guides are additionally coupled together with rails further reducing twisting and warping of the guides. The terminals are advantageously mounted in strip form for ease in manufacture and assembly to the substrate.
