Patent GB-372733-A (GB)
Abstract: 372,733. Bookbinding. KUSTERS, T., 54, Willibrordusstraat, Amsterdam. Nov. 6, 1930, No. 33449. Convention date, Nov. 7, 1929. Void [Published under Sect. 91 of the Acts]. [Class 16.] Relates to the manufacture of books, in which the printed matter is so arranged o the sheets that two books are produced for binding at one operation. In order to avoid the necessity for double composing of the type matter, each sheet is printed for one half of its area with a number of normally consecutive pages, and for the other half of its area with a number of pages, also normally consecutive, which lie as far from the last page of the book as the others lie from the first page, some of the pages being left blank, if necessary. For example, for a pamphlet of 128 pages, one sheet would bear pages 1 to 16 and pages 113 to 128, a second sheet, pages 17 to 32 and pages 97 to 112, and so on. For a pamphlet of 32 pages, the formes are so arranged that, when the printed sheet is folded along the lines AB, CD, EF, Fig. 1, a double signature of the form shown in Fig. 3 is produced, of which the upper half contains pages 1 to 16, and the lower half, pages 17 to 32. Another identical signature is placed upon this in reversed position, and the two signatures are cut on the line GH, so as to produce two complete books.

Abstract: 1,187,041. Extruding; forging; die casting. JACO ENG. CO. Ltd. 25 Aug., 1967 [27 Aug., 1966], No.38519/66. Headings B3F, B3H and B3P. [Also in Division F1] Press and casting dies are cooled and lubricated by spraying with a coolant alone and subsequently with lubricant. A plurality of spray nozzle assemblies 10 are supplied with compressed air from a compressor, air line or reservoir 25. Each nozzle, Fig. 2, has a pair of Venturis 36, 37, an air inlet 35, coolant inlet 34 and lubricant inlet 33. The air extracts a coolant such as water from a tank 20 or from a pump or main supply, and also lubricant from a tank 14. The lubricant is fed by a pump 15 through a control valve 16 and a proportioning valve 13 which is preferably of the kind described in Specification 1,187,042. The dies may be used in a die casting, extrusion, stamping or drop forging process. In operation, the supply of compressed air is started by opening a valve 26 controlled through mechanical or electrical linkage, by the opening movement of the dies or by a heat sensor device. This extracts water which is sprayed through outlet tube 30 on to the dies. Following a predetermined interval a relay or delay mechanism, which may be controlled by a heat sensor responsive to the drop in die temperature, opens the valve 16 thus admitting the lubricant to proportioning valve 13 and hence to the nozzles. The valve 13 has a central means 60 which regulates the proportion of coolant to lubricant. Subsequently both valves 26, 16 are closed before another work cycle commences. In a drop forging machine the workpiece may be transferred successively to die sets each having cooling nozzle assemblies which may be fed from the same coolant and lubricant source through separate proportioning valves. The lubricant may be in the form of a thick slurry or a viscous paste or liquid. Colloidal graphite is referred to.

The transistor collector is connected via capacitor 14 to earth and when the transistor conducts this capacitor acts as a low impedance source of negative voltage. After the charge in the gate has been removed a current still flows via the collector base junction to recharge the capacitor for the next cycle. The circuit can be driven as shown from a transformer 6 or from a tapped choke (Fig. 6, not shown). In either case the circuit eliminates the time constant caused by leakage inductance in the transformer/choke to give a faster turn off.
