Title: Meal-vending machine
Inventor: KNOLL HANS
IPC: G07F9/10
Filed: 1988-05-06
Abstract: A meal-vending machine (10) has a magazine (30) for a plurality of portioned meals, a heating station (35) for the meals, at least two dispensing stations (19, 20) for the heated meals, transport devices (32, 36, 39) for transferring the meals between the magazine (30), the heating station (35) and the dispensing stations (19, 20), and a control unit (50) with a program-control mechanism (73) for the synchronised actuation of the magazine (30), heating station (35), dispensing stations (19, 20) and transport devices (32, 36, 39). So that a multiplicity of heated meals can be dispensed in a short time, irrespective of the particular heating time required, a keeping-hot and storage station (41, 43, 60 to 64) is arranged between the heating station (35) and the dispensing stations (19, 20). The heating station (35) contains a number of lugs which is smaller than the number of dispensing stations (19, 20). The control unit (50) has a data memory (52) for storing a number of meal-selection commands (51) and for the time-offset activation of the magazine (30), heating station (35) and transport devices (32, 36, 39). This ensures that a preselectable number of heated meals is kept ready in the keeping-hot and storage station (41, 43) at a preselectable moment. <IMAGE>

The proportion of units (A) and of the sum of units (B) and (C) is each 100 mol-%, the proportion of units (C) being up to 50 mol-% and, if Z represents -SO2-, up to 75 mol-%. The Staudinger index [ eta ] of the copolyether amide is in the range from 50 to 1000 cm3/g, and the value of the glass transition temperature is above 200 DEG  C. The copolyether amide is prepared by a low-temperature solution, solid, interface or melt condensation process. The moldings produced therefrom in the form of filaments, wires, films and other moldings are obtained by processing the pulverulent copolyether amides or their solutions.

The movable pulley members (4, 6) are actuated by hydraulic servos (A1, A2), loaded by pressure supplied by a pump (8) through a control valve (9) for adjusting and maintaining the transmission ratio. Servos (A1, A2) on the primary shaft (1) and secondary shaft (2) each have an associated torque sensor valve (10, 11) different from that of the other servo. One sensor valve (11) is preceded in a hydraulic control circuit by a minimum pressure valve (12) and followed by the other sensor valve (10).
