Abstract: A trolley device capable of lifting and moving an open topped container, comprising a body part having handle means and means which permit movement of the device along a surface, the body part having primary container-contactable means including at least one container-contactable part located above ground level when said body part is upright which can engage a lower external side of such a container, and secondary container contactable means including at least one container-contactable part spaced above the said primary contacting means when said body part is upright and which can engage an upper internal side of the container, said body part capable of pivoting about the said means which permit movement to raise both said container-contactable means.

Abstract: A potting compound injection apparatus includes a pneumatic tube for inserting single part potting compound and injecting the compound into the cells of a composite panel. The pneumatic tube has an open end for releasing potting compound and an opposed end interconnected to a pneumatic pressure source. The potting compound injection apparatus may also include a frame for maneuvering the pneumatic tube with respect to the composite panel. A method of injecting a potting compound includes applying potting compound through a pneumatic tube into a composite panel having cells.

Abstract: The invention is directed to techniques for transferring data using a device driver that is arranged to prevent improper operation of a non-primary routine (e.g., an administrative operation) from causing improper operation of a primary routine (e.g., a data transfer operation). Accordingly, the primary routine can continue to operate properly after a failure of the non-primary routine. In one arrangement, a data communications device transfers data. The data communications device includes a port that couples to a network, and a processor coupled to the port. The data communications device further includes memory, coupled to the processor, that stores a device driver. The device driver has a first set of instructions that directs the processor to perform a data transfer routine that moves data between memory and the port, and a second set of instructions that directs the processor to perform an administrative routine.

Abstract: A vehicle adapted for transporting and manipulating objects within a confined space, such as a tunnel. The vehicle comprises a pair of side frames interconnected by vertically adjustable front and rear interconnecting members that include horizontal portions onto which a boom is slideably and pivotally connected. Raising and lowering of one or two of the interconnecting members and lateral traversing of one or two of the connected boom portions provides for manipulation of an object or tool attached to the boom.
