Abstract: 1,229,171. Routing baggage trucks. BENDIX CORP. 13 May, 1969 [6 June, 1968], No. 24380/69. Heading B7H. In a baggage handling system for routing baggage in trucks 20 via track 22 to different points in an airport, baggage ownership and address information is fed into a memory forming a part of a radio transmitter and receiver device 19 on the truck carrying the baggage and the information when transmitted is read and where necessary acted on by receive and routing elements &c., controlling the route followed by the truck. At entry points such as the parking lot 26 or the airline office 21, a segmented baggage ticket 11, 12, 13 is made out with a baggage claim number, and the flight itinerary-airline, flight number, flight transfer information &c. A portion 11 of this ticket is then read by apparatus 15, 17 and the details in binary form are transmitted via a very short range transmitter to a receiver forming a part of the unit 19 carried by the truck 20 on which the baggage is loaded. The information is stored in a circulating register in unit 19 and then transmitted back to the apparatus 15, 17 for check purposes. If correct, the apparatus actuates a brake, thereby releasing truck 20 for its journey. During its journey the truck apparatus 19 which is alternately switched to transmit and receive modes each of 4 m.secs., transmits a signal which is received, only in passing because of the short range, by trackside units 30, 32 and 35. Trackside units 30 are fixed address units and serve to route the vehicle from, e.g. the main loop 22a, 22b, 22c to loops 22h, 22j &c., each associated with one airline. Each is provided with a counter unit which selects only that part of the information transmitted, e.g. the airline number, with which the unit is concerned and if this address information matches that permanently stored then the truck is switched to the required loop. Trackside units 32 are associated with the flight numbers and are provided with an address store which can be programmed with the flight numbers. These units are provided at the flight points with loops 24, 25 or at the hold areas 31 to which baggage awaiting flight is routed. Baggage arriving at the flight areas is loaded on individual trucks 20 each with a device 19 which receives its route information via apparatus 15, 17 which reads a further portion of the segmented baggage ticket 12. The truck is routed either to the area 31 if it is to continue on another flight or if the trip is terminated to a baggage claim recirculation area 33. Passengers at the parking lot 27 or taxi rank 27 can now claim their baggage by inserting their part 13 of the baggage ticket in the associated apparatus 15, 17. By land line the baggage claim number is transmitted to a unit 35 adjacent the recirculation area and when this unit detects the baggage circulating in the loop 33 transmits to the associated device 19 the address 30e, 30f for collection.

Abstract: 1,233,353. Transistor circuits for insulating a diode. INTERNATIONAL BUSINESS MACHINES CORP. 6 Feb., 1969 [22 March, 1968], No. 6446/69. Heading H3T. A circuit for simulating a diode characteristic has a diode D and resistor R5 connected from an input terminal 1 to one pole of a voltage source 3, a control circuit having an emitter coupled pair T1, T2 with the base of transistor T1 connected to the input terminal and the base of transistor T2 connected to a bias potential, and biasing transistors T3, T4 controlled by the control circuit T1 T2 to bias the diode conductive whenever the potential on the input terminal 1 exceeds the bias potential. As shown, the circuit uses NPN transistors and simulates a diode having the anode as 1 and the cathode as 2. When the input 1 is negative transistor T1 and diode D are off and transistors T3 and T4 are on. As the input increases positively transistor T1 conducts. This decreases the emitter potential of T4 and when the emitter potential of T4 becomes more negative, e.g. by 0.5V than the input 1 diode D conducts and current flows through R5 to the cathode 2. In a modification (Fig. 3, not shown), the bias potential for T2 is obtained from a tapping on a voltage divider (P) connected across the voltage source. Also a further voltage source (4) may be connected between R5 and via an external circuit (5) to the input terminal 1. Alternatively one of the voltage sources may be formed by tapping the other. The circuit may be made in monolithic semiconductor wafers and uses include limiters and amplifier input stages. Specification 1,215,334 is referred to.
