Abstract: A bicycle stand including a stationary upright member anchored to the ground and horizontally oriented enclosure of rectangular cross section attached to its top with an opening in one side thereof to receive a bicycle securing arm. A pivotable second member carrying three arms is adapted to engage a bicycle. One of the arms is aligned with and adapted to pass through the opening, an aperture to receive a leg of a shackle lock placed within the enclosure to lock the bicycle in the stand. A storage compartment can serve as one of the upright members and is secured by the same lock.

Abstract: A method and apparatus for verifying the proper airing of television program having a digital identification code recorded on a preselected scan line which is not normally visible to the television viewer. A plurality of television channels are automatically simultaneously monitored by a primary monitoring system at a site 30 within the reception area and broadcast encoded programs are identified and timed and appraised as to their audio and video signal quality. The information generated is stored locally for later comparision with centrally stored 62 information specifying the program that should have been aired. Each of the channels is sequentially monitored for a preselected fixed time interval, which depends on the number of channels being monitored, under the control of a programmable sequential controller 54. A secondary monitoring system is provided for use as a backup or for monitoring cable channels.

Abstract: Photocopy machine having a feed module for successively feeding individual original documents from a stack thereof. Cooperating portions of the feed module and of the photocopying machine form a straight line original document feed path having an entryway that is accessible for conventional insertion of original documents. The feed module includes apparatus for successively feeding original documents from a stack along a direction reversing path that leads to the above entryway of the straight line feed path. The feed module can be pivoted to afford access to the straight line original document path and to permit copying of original documents which cannot be sheet fed. The feed module includes an original document separating arrangement wherein a feed tire and flanking retarder bars are cooperatively disposed so as to obviate need for any adjustment of the arrangement to afford proper feeding of documents of variable thickness.

Abstract: Apparatus for varying the nozzle area in the turbine section of a gas turbine engine is disclosed. Nozzle guide vanes extend across the flow path for the working medium gases and are rotatable to alter the area of the nozzle. In one embodiment the rotatable vanes are cantilevered from the outer engine case and are opposed at their radially inner ends by a shroud which is affixed to the inner engine case.
