  • Patent number: 5732919
    Abstract: A stowable monitor life apparatus is described. The invented lift apparatus employs two different biasing mechanisms for deployment of a monitor support structure, thereby reducing the space required to house the apparatus with its associated monitor while promoting quick and easy deployment and stowage of the monitor within the system's housing. Preferably, the biasing mechanisms take the form of a pivotal gas spring in combination with a coil spring, whereby the coil spring acts along a generally vertical axis to partially deploy the monitor support structure and to pivot the nominally horizontal gas spring into an inclined orientation that enables it to complete the lifting of the monitor support structure. Thus, the two springs assist one another upon manual deployment via a pushbutton release mechanism.

  • Patent number: 5090313
    Abstract: An apparatus for making multi-color silk screen prints on dimensionally unstable material such as T-shirts includes a platen, to which the shirt is adhesively affixed, that is removable from the remainder of the apparatus with a shirt attached to it without loss of registry between the shirt and silk screens carried by the apparatus when the platen is reinstalled on the apparatus. This permits moving the platen from one apparatus to another thereby printing more colors than would be possible with either apparatus alone. The apparatus also permits removing the shirt from the apparatus to perform a non-silk screen process between the printing of colors. In a preferred embodiment of the invention the removal of the platen is accomplished by dividing the platen into a bottom piece that is attached to the remainder of the apparatus and a top piece that is releasably attached to the bottom piece.
