Filed: 1974-02-08
Abstract: 1429737 Electronic watches DAINI SEIKOSHA KK 8 Feb 1974 [23 Feb 1973] 05944/74 Heading G3T [Also in Division H2]  An electronic timepiece comprising a timing circuit for producing a time indication on a liquid crystal display, is provided with an astable blocking oscillator circuit, Fig. 2 including a rectifying element D arranged to be connected to a battery 18 to produce a rectified voltage higher than the battery voltage to power the liquid crystal display. Assuming collector current flowing in a transistor Q Fig. 2, terminals 1 and 2 of a coil L2 will be positive and negative respectively and negative and positive potentials will be induced at terminals 3,4 respectively of a coil L 1 ; (coils L 1 , L2, L3 being magnetically coupled on a common pot core Fig. 3, (not shown). This results in increased base current in Q and hence increased collector current. As soon as capacitor C, in an RC control circuit, becomes charged, the transistor Q is rendered non-conductive, so that the polarity of coil L2 reverses and at the same time negative and positive potentials are induced at terminals 5, 6 respectively of Coil L 3 . Diode D will therefore conduct and a voltage will appear across C 2  which is the sum of the battery voltage and that induced in L3. In Fig. 1 (not shown) this higher voltage is also used to power minutes and hours counters (13) (14) respectively and driving circuits (15) (16) coupling the counters to the liquid crystal display.

Title: Improvements in and relating to control devices for expanding mandrels on machines for printing and varnishing hollow bodies
IPC: B41F17/18
Filed: 1960-02-22
Abstract: 888,796. Printing on curved surfaces. MASCHINENFABRIK WINKLER FALLERT & CO. A.G. Feb. 22, 1960 [March 13, 1959], No. 6168/60. Class 100(2) [Also in Group XXII] Expansible mandrels 2, 3, for supporting hollow bodies 44 during printing or varnishing are controlled by a mechanism which ensures that the mandrels are expanded and collapsed at the appropriate times to grip and release the bodies. The mandrels 2, 3 are mounted on an intermittently rotatable turntable 1. Each mandrel has a sleeve 4, Fig. 4, carrying a bush 7 supported by ball bearings 5, 6. A member 9 carrying a tapered needle 10 is slidable within a bush 8 located in the bush 7. The member 9 is connected with a lever 12 engaging a fork 14 secured to a bolt 15. The needle 10 engages tapered surfaces on segments forming the expansible mandrel to expand the mandrel, the needle being pressed outwardly by a spring 16 to expand the mandrel. In operation, the turntable 1 is stopped with the bolt 15 of one mandrel 2 in axial alignment with a bolt 21, Fig. 2, of an air cylinder 18 connected to a valve 26 controlled by a cam 32. The valve 26 opens to cause the bolt 21 to press on the bolt 15, thereby collapsing the mandrel 2 to allow a hollow body 44 to be manually or automatically mounted on the mandrel. Further rotation of the cam 32 causes closure of the air valve 26 to permit mandrel expansion. The turntable rotates further, such that the hollow body 44 passes a printing station 38 where it is printed in one or more colours. The mandrel is collapsed to permit withdrawal of the hollow body when the bolt 15 is in axial alignment with a bolt 22 of an air cylinder 19 connected to a valve 27 controlled by a cam 27. If a hollow body 44 is not present on the mandrel 3 when passing the printing station 38, a limit switch 43 is not actuated and the circuit to an electromagnet 29 remains closed, such that air flows through a pipe 28 to an air cylinder 20 to collapse the mandrel. Hydraulic rams may replace the air cylinders 18, 19 and 20.

Abstract: 696,192. Gas turbine plant; axial-flow compressors. SULZER FRERES SOC. ANON. March 14, 1952 [April 14, 1951], No. 6706/52. Classes 110(i) and 110(iii) In a plant for producing compressed air in which the working air compressor 1 is driven by a gas turbine 4 which has its own compressor 2 for its working medium, the compressor 1 is connected through a conduit 24 to the flow path of the working medium at a point 25 after its compression to its highest pressure; this point may be between the compressor 2 and a heat exchanger 5, as shown, or between the heat exchanger and a combustion chamber 3, or at the combustion chamber itself. The flow of air thus bled from the compressor 1 is adjusted by a valve 26. By this means, the amount of air delivered through a pipe 23 to the point of use, which may be a blast furnace, can be regulated. Further regulation can be effected by blowing off air through a valve 28. A cooler and a non-return valve may be arranged in the conduit 24, and a regulating valve may be provided in the pipe 23; preferably beyond the connection to the conduit 24. Fuel gas, such as blast furnace gas, is supplied by a compressor 6 to the combustion chamber 3, the supply being regulated by adjusting a valve 20 and also by returning a proportion of the gas to the inlet of the compressor 6 through a pipe 16 having an adjustable valve 17 and a cooler 18. An alternating current dynamo-electric machine 30 normally acts as a generator to supply a network 31, but on occasion it acts as a motor to assist the turbine 4. It is connected to the turbine 4 through gearing 29 and, it may be, means for disconnecting the drive, such as a hydraulic coupling or torque convertor or disengageable gearing. The turbine 4 exhausts through the heat exchanger 5 to preheat the combustion air.
