    摘要: The modular jack allows a RJ series connector plug to be attached to a communications card that conforms to the PCMCIA requirements for a Type III card. The modular jack includes a main body portion including a top surface, a bottom outer surface and a front surface. The receptacle is disposed entirely within the front surface of the modular jack such that no portion of the plug extends through either the top surface or the bottom surface of the main body portion of the modular jack. Thus, the modular jack allows the communications card to be connected to standard RJ series plugs without deviating from the Type III PCMCIA card height requirement, even when the plug is inserted into the jack. Desirably, the main body portion has a height measured from the top surface to the bottom surface that is generally equal to or less than about 10.5 mm. Additionally, the receptacle preferably includes an upper inner surface and a lower inner surface that are separated by a distance that is generally equal to or less than about 10.1 mm. The modular jack may also include a latching area that securely holds the connector plug within the receptacle, but allows the connector plug to be removed from the receptacle without the user depressing a biased clip of the connector plug if a predetermined force is applied to a body of the connector plug.

    摘要: A communications card capable of being mounted in electrical communication with a computer has formed therethrough an aperture so sized and shaped as to be capable of receiving a physical/electrical media connector. A plurality of contact wires are disposed in the aperture. The contact wires have a tapered section formed thereon for preventing embedding and damage to the contact wires caused by plugging and unplugging the physical/electrical media connector in the aperture. The contact wires also have a remote end that is substantially rounded. The cross-section of the media connector is greater than the thickness of the communication card. The physical/electrical media connector also has a biased retention clip, a contact pin block, and contact pins. The retention clip has several standardized characteristics including a broad fixed end protruding from an outer surface of the contact pin block. The broad fixed end tapers abruptly at a transition notch down to a narrow free end, capable of being manipulated by a user to remove the physical/electrical media connector from the aperture in the communications card. In use, a physical/electrical media connector is inserted directly into the aperture in the communications card, the aperture being in contact with a plurality of contact wires fixed within the communications card. The aperture is formed either within the communications card itself, or within an aperture block in electrical communication with the communications card.

    摘要: A card holder for housing, for example, plastic patient identification cards which have on them vital patient information and tabbys, i.e., tabs which have on them room or bed numbers and which normally are adhesively affixed to the card holder is fabricated of metal, preferably stainless steel, and is of a size substantially corresponding to the size of the identification card to be removably supported by it. Being of metal, the useful life of the card holder is far greater than those of plastic. The card holder has parallel side edges, each of which has at least one and preferably two upstanding stops integrally formed therewith, which stops have a height substantially corresponding to the thickness of the identification card. These upstanding stops prevent lateral movement of the identification card with respect to the card holder. In addition, a generally L-shaped retainer is integrally formed with each of the parallel top and bottom edges of the card holder, and these L-shaped retainers form slots for receiving therein the upper and lower edges of the identification card to effectively secure the identification card in and affixed against movement to the card holder. A tab portion also is integrally formed with the top edge of the card holder, and indicia such as a room or bed number is permanently embossed on this tab portion, thus eliminating the need for adhesively affixed tabbys and the like. Preferably a support tab is fixedly secured beneath the tab portion on its backside to support the tab portion during imprinting, so that a clear print of the embossed indicia is provided. A semi-circular cut-out in at least one side edge of the card holder is provided to assist in removing the identification card from the card holder.

    摘要: This invention relates to an improvement in a process for preparing toluene diamine. The improvement resides in a process which is capable of permitting reduction of dinitrotoluene to toluene diamine without prior alkaline treatment for removal of nitrocresols in the dinitrotoluene. In carrying out the improvement the feed dinitrotoluene is water washed to remove HNO.sub.3 to a level below 6000 ppm, and the catalytic conversion of dinitrotoluene to toluene diamine is done continuously. Dinitrotoluene is charged to a reaction vessel containing a liquid carrier and reduced with hydrogen at constant pressure, the dinitrotoluene being added at a rate to maintain a concentration of dinitrotoluene of 0.0001 to 25% by weight of the total reactor contents while the hydrogenation catalyst is maintained at a level from about 0.1 to 3% based on the weight of reactor contents.
