Title: Coin testing device for small slot machines - is especially suited to use in telephone coin-boxes
Inventor: BACHFRIEDER HEINZ
IPC: G07F1/02
Filed: 1974-02-21
Abstract: A coin slot in a coin plate takes up an outward position under spring pressure. A coin inserted moves two sense arms; one for diameter and the other for thickness, and itself rests on a divider below the slot. The two sense arms move plates at the rear of the mechanism in the vertical and horizontal directions. These plates have orifices cut in them which allow a rod connected to the sprung coin plate to pass or not dependant on whether or not the coin checks are within tolerance. The coin is thus dropped to one side of the divider by it being moved to one side and the coin returned or to the other side into a different coin slide as an intermediate store where it is held by a second divider. The second divider may cause the coin to pass to a coin cassette or to the returned coin outlet.

Patent DE-2449039-A1 (DE)
Inventor: BECKENBACH KARL DIPL ING
IPC: F27B1/20
Filed: 1974-10-15
Abstract: The charging of the gas- or oil-fired shaft furnace with the material to be burned and sintered, such as lime, dolomite, magnesite or cement, is effected by means of a bell (30), after which the material passes successively through an inlet zone (12), a preheating zone (14), a burning zone (16) and a cooling zone (18). By means of the bell (30), the material is brought, during sinking down, up to the furnace wall at the upper end of the inlet zone (12). The material slopes down from the furnace periphery to the furnace centre (24) which is covered by the central part of the bell, so that a large depression is formed in the furnace centre. The relatively coarse pieces of material collect around the longitudinal furnace axis (24) and above the combustion chambers in the form of a pillar, whose cross-section approximately has the shape of a circle with protruding circular ring sectors, while the relatively fine pieces of material migrate through the furnace outside this pillar. The expensive preclassification of the material becomes unnecessary. <IMAGE>

Patent DE-2462165-A1 (DE)
Title: Protection circuit for microwave heating system - makes use of upper and lower limit electronic comparators in order to control generator
Inventor: BOETTCHER LUTZ DIPL ING
IPC: H05B6/68
Filed: 1974-03-23
Abstract: The microwave heater is used for raising stored blood to normal body temperature, for use in transfusions, from the storage temperature of approx. +4 deg.C. A resistive temperature detector (51) provides one input to each integrated circuit comparator (52, 53). The other input corresponds to the required temperature (U5) in one case, and to a predetermined minimum temperature (U4) in the other. Both comparators give an 'on' signal to the microwave generator when the actual temperature lies between the reference limits, but either comparator can give an 'off' signal if its reference value is reached. Damage or malfunction associated with the detector (51) giving an artificially low temperature signal would thus cause the equipment to switch off thereby eliminating the possibility of further damage.
