Abstract: Apparatus for transporting cards containing data to be scanned at a reading station by a single transport roll against which the cards are held in proper reading alignment as the cards are transported past the reading station, the transport roll being circumferentially grooved, and the cards being held against the transport roll by pressure applying means confronting the bottom of the groove within the axial extent of the groove.

Abstract: A data card feeding station in which a stack of cards is aligned and removed one-by-one from the stack by a feed roll and a pressure applying spring under the control of a card engaging plate which is actuated on command to allow engagement of a card between the feed roll and the spring.

Abstract: The invention is concerned with fasteners which are used to secure a plurality of plates, or other structural members, together in an interference fit between the fastener and the plates to impart a residual hoop stress within the structural members and around the hole through which the fastener extends so as to obviate fatigue failure in the structural members in the vicinity of the hole. The fastener assembly of the invention comprises the combination of a flared sleeve of relatively soft material, and a tapered mandrel of relatively hard material. The mandrel is first driven into the sleeve at the factory in a preliminary interference fit with the sleeve, and the sleeve is then finish ground to the final tolerances, so that each mandrel and sleeve becomes a matched pair.

Abstract: A battery operated thermometer by which a person's temperature is measured by a thermistor which varies the current flow through a resistance bridge circuit, and the temperature is shown by adjusting a dial to adjust a meter to a null point. A quick connector is employed to connect the disposable probe in the bridge circuit. The probe consists of a pair of conductor wires in an insulating sheath and having bared ends held by pressure only in conductive contact with a thermistor chip by a plastic tip which shrinks to press the bared ends against the chip.

Abstract: Sorting apparatus has vertically adjustable sheet receiving and feeding vacuum chamber and traveling belt mechanism which directs successive sheets to a receiver having vacuum chamber and traveling belt conveyor mechanism for transporting sheets to or past vertically spaced trays. Fingers are shiftable to and from positions to deflect sheets from the transport conveyor and cause sheets to enter the trays. The receiving and feeding mechanism and the receiver are separable at the vertical plane of the fingers between the fingers and the vertically extended traveling belts.
