Abstract: 1535614 Registering sheets INTERNATIONAL BUSINESS MACHINES CORP 9 Feb 1977 [23 March 1976] 5245/77 Heading B8R [Also in Division G3] A device for feeding two documents from an entry station 10 to a platen 12 of a copier comprises photoelectric sensors 96, 98 which detect the presence of the documents and energize rollers 20, 18 respectively to align the documents with their front edges against gate 24 and their sides against fences 26 and 22, respectively. After alignment, gate 24 is retracted and a belt drive 14 drives the documents forward, rollers 20, 18 maintaining their sides against the side fences 26, 22, up to an exit gate 17. After completion of the copying cycle the exit gate is retracted and the belt 14 driven again to eject the documents and a fresh pair of documents, prealigned in the entry station are admitted. The operation of the system is automatically controlled by logic circuitry (see Division G3).

Abstract: 1,224,970. Circuit board assemblies. INTERNATIONAL BUSINESS MACHINES CORP. 12 Jan., 1970 [16 Jan., 1969], No. 1357/70. Heading HlR. The invention, a ventilated circuit board assembly for mounting in a machine frame, comprises circuit boards (glass epoxy laminated structure) 17, 19, and frame members 11, 13, 15 (thermosetting filled phenolic resin) secured in a stack so that the circuit boards are trapped by the resilient members 43 on the end frames 11, 15 and abutments 45 on the inside frame 15 thus providing location (pins 63, 64 and holes 65, 66) and vibration damped support for the circuit boards. Rubber cushioning members 41 which may be replaced by dome-shaped rubber bumpers on projections 43 are provided. The circuit boards carry connecting shrouds 53, 75 on the connector projections 73 to effect interconnection and external connection (Figs. 2 and 3, not shown). Additional circuit boards and frame members may be included and ventilation is by convection in the channels formed by the abutment and resilient members.
