Title: Matching Parison Production Rate to Bottle Blow Moulding Rate
IPC: B29C49/64
Filed: 1980-02-19
Abstract: In a machine system for continuous formation of molecularly oriented plastic bottles by blowing heat-conditioned parison comprising a plurality of parison-forming stations, e.g., sixteen; a plurality of blowing stations, but fewer in number than the number of parison-forming stations, e.g., four; and a storage area between the parison-forming and parison- blowing stations, improvements are described primarily in the storage area and in the mechanisms for transferring the hot parisons. A carriage (201) (figure 3) carrying sixteen jaws is reciprocated by a cylinder (230) into and out of an injection mould (100) to transfer sixteen injected parisons at a time onto expandable collets. The carriage jaws (210, figure 4) are opened and closed as two sets of eight by scissor linkages (220), cylinders (232, 234) and racks (231). A rotary transfer mechanism 247 (figure 8) carrying the collets transfers the sixteen parisons 8 axially away from the jaws (210) and then rotates about axis 276 to move the parisons from horizontal to vertical positions at the storage area plate 300. Pairs of jaws 303 (figure 12) clamp the parisons. One jaw supporting plate 304 of each pair is moved by a cylinder 314, to operate a rack and pinion 310 for moving the other jaw supporting plates 302. Heating pockets condition the parisons at the storage plate 300. The parisons are then received on a reciprocated transfer carriage (figure 18) by four sets of jaws 422/466 which are individually opened 406/closed 404 about four parisons by cylinders 412. The jaw sets are moved sequentially to a shuttle (figure 25) which shuttles four parisons at a time to the four blow moulds, while depositing four blown items on a lead- off conveyor. The cooled blow moulds, pins and stretch rolls are operated by toggle linkages (figure 22). <IMAGE>

Patent GB-2090034-A (GB)
Title: A circuit arrangement in a coin checker
IPC: G07D5/08
Filed: 1981-11-24
Abstract: The coins (37) come within the coil field of an oscillator (2,6,7). Within a reverse feedback path of the oscillator amplifier (2), several resistances (11 to 18) are arranged, switchable parallel to each other individually or in any desired combination, by switching transistors (21 to 28), each controlled by a program (29). This makes the amplification controllable step by step. The program (29) has a constant-value-storage (49) with a stored standard value for the amplification in which oscillations cease whenever the field coil area is free and a calibrating resistance (35) is connected parallel to the condenser (7) of the oscillator (2,6,7). For each coin type, two pre-determined standard limit values of amplification are stored in the constant-value-storage (49), with the oscillations ceasing between them in the presence of an acceptable coin (37). Prior to each testing operation, the program (29), with calibrating resistance (35) being connected parallel to the condenser (7) increases the amplification step by step until oscillations cease. The quotient of the thus obtained amplification value and the standard value is multiplied by the two standard limit values of each type of coin, and the product is stored in the read-write-memory (59) as the nominal limit value. During the coin testing, the amplification is altered step by step from the highest nominal limit value to the next lower, and so on. A coin acceptance signal is issued whenever the oscillator oscillations do not cease with the higher of the two nominal limit values and do stop with the lower of the two nominal limit values.
