Title: Direct connection system for removably engaging a physical/electrical data transfer media connector in communication with telephone data transfer line with a communications line
Inventor: ALDOUS STEPHEN C
IPC: G06F1/16
Filed: 1992-06-05
Granted: 1994-10-18
Abstract: A  communications  card  capable  of  being  mounted  in electrical  communications  with  a  computer  has  formed therethrough an aperture so sized and shaped as to be capable of receiving a physical/electrical media connector.  The media connector 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 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 communications card is divided into a retractable access portion of the communic-ations card which can be directly accessed by manipulating an actuating  mechanism  releasing  a  retention  means  thereby allowing a spring to push the retractable access portion of the card outside of the computer housing.   The retractable access portion of the communications card may be reinserted back into the computer housing to be carried internally when not in use.

Abstract: A car catcher is pivotally mounted to an elevated frame structure of a roll-off hoist at an end which protrudes rearwardly from a vehicle beyond the rear wheels thereof.  Chains establish a downwardly pivoted operative position of the car catcher by interconnecting the frame with the hoist.  A pivotal latch lever moved by the same actuator used to raise the catcher from an operative to an inoperative position is positioned to a confronting relation with a jam lock to prevent unwanted lifting of the catcher from the operative position.  The actuator moves the pivotal latch lever free and clear of the jam lock against the stop to allow, under control by an operator, pivotal movement of the car catcher to an inoperative position as desired during loading and off-loading operations by the hoist.

Abstract: A chemical vapour deposition method is provided for case hardening a ferrous metal interior tubular surface by exposure to diffusible boron with or without other diffusible elements such as silicon to enhance the wear, abrasion and corrosion resistance of the surface. The pack composition used allows for borosiliconizing of the interior surface without sintering or adhering to itself and/or adhering to the surface. The pack composition comprises between about 5% and about 20% by weight of a suitable source of boron; between about 2% and about 10% by weight of silicon material; between about 2% and about 15% by weight of an activator; and the balance being a non-sintering, non-adhering filler. The pack composition is substantially free of diffusible carbon thereby minimizing carburization of the interior surface of the tubular member, and remains free-flowing after the heating and cooling steps, to permit the treatment of continuous lengths of the interior surface of the tubular member whereby the pack composition flows freely from the tubular member interior after the treatment.
