Title: Improvements in make-ready element for printing presses and method of making the same
IPC: B41N10/04
Filed: 1931-12-29
Abstract: A non-porous, resilient material, resistant to the action of printing-ink, oils, and cleaning-solvents and not liable to be embossed contains a polymerized reaction product of sulphur and a halogenized unsaturated hydrocarbon, and less than half as much vulcanized rubber, and is applied to a base of wool felt, woven cotton fabric, or paper to produce a make-ready element for printing-presses.  The reaction product is prepared by the action of sodium or other alkali or alkaline-earth polysulphide on dichlorethylene, dibromethylene, or similar compounds of the higher members of the olefine series.  The product is rendered plastic in a mill, and rubber, which has also been rendered plastic, is mixed therewith, diphenyl guanidine being then added. Paraffin, stearic acid, a plastifier such as sulphurized Burgundy pitch, an accelerator such as mercapto-benzo-thiazole, zinc oxide, carbon black, and sulphur are mixed separately and added to the other ingredients.  The rubber, paraffin, and stearic acid are added to facilitate the subsequent calendering of the mixture, the mercapto-benzo-thiazole and sulphur act to vulcanize the rubber, the carbon black increases the strength and toughness of the material, and the zinc oxide acts to render the material less tacky and more durable.  The material is then applied to the base in a calendering-machine.  A layer of the mixture, to which materials such as cork have been added, may be applied to the base beneath the final coating of the mixture.

Abstract: 1,060,306. Transistor gating circuits; multiplex pulse code signalling. R. DESSOULAVY. Sept. 17, 1963 [Sept. 20, 1962], No. 36502/63. Headings H3T and H4L. In a transistor gating circuit for controlling the application of signals from a source E to an output line b, switching voltages applied at terminals e 1  control the conductivity of transistor 1 provided that the voltage applied at terminals e 2  is large enough to maintain transistor 2 non-conductive; when transistor 2 is permitted to conduct, however, transistor 1 is biased off by the voltage applied to its base from source 4 so that the switching voltages applied at e 1  cease to control the connection of the source E to the output line b. In a pulsecode-modulation time-division-multiplex sytem, Fig. 2 (not shown), three circuits each as shown in Fig. 1 are employed. Three-phase pulses e 2  are applied to the transistors 2 so that only one is non-conducting at any one time, the corresponding transistor 1 thus being the only one of the three transistors 1 which is controlled by the switching voltage e 1  applied thereto from a common pulse generator through a multiplewinding transformer. Information signals E 1 , E 11  E 111  are thus sampled in turn by the switching voltage e 1 , the chopped output from the transistors 1 being applied to a comparator circuit where the amplitudes of the incoming pulses are compared with a step-wave voltage synchronized with pulses e 1 , the results of the comparison being applied to logic circuit network which derives therefrom the desired pulse coded binary signal.

Abstract: 1317802 Compressing and packaging stacked bags WINDMOLLER & HOLSCHER 28 July 1970 [31 July 1969] 36552/70 Heading B8C A stack of bags St is compressed and packaged by apparatus comprising a forked plunger 20 which introduces the stack into a pivotable chamber or L-shaped receptacle (43, 44, Fig. 5), two freely rotatable rollers 15, 16 for supporting two sheets F 1 , F 2  which are transversely sealed together to form a web stretching across the chamber or receptacle so that the web can be taken thereinto by the moving stack and an hydraulically or pneumatically actuated folding device 4 which moves across the front of the receptacle or chamber 1 to maintain stack compression as the plunger 20 is displaced (in the direction of arrow b) at the end of its compression stroke and to pull the sheet F 2  across the stack undersurface to that portion of sheet F 1  lying beneath a reciprocable welding jaw 3 so that a stack sleeve M may be formed and the sheets F 1 , F 2  re-interconnected. The folding device 4 comprises a series of triple rollers. The receptacle or chamber 1 may be provided with an adjustable backing member so that a compressed stack of a desired height may be obtained. During welding the plunger 20 is lowered (arrow c) and carried on a transversely moving crosshead 23 (arrow d) so that its prongs pass through a longitudinally slotted stack guide wall 19 into a grid 26 to be ready to lift the next stack mechanically or manually placed on the grid. After welding, the jaw 3 is lifted, the folding device 4 withdrawn and the chamber 1 or receptacle is swung to a discharge station 8. The chamber 1 may be swung clockwise together with the jaw 3, or anti-clockwise (Figs. 4, 5) without the jaw 3. The stack 1 may be prevented from dropping out of the chamber 1 during swinging by either a holding plate extending along the chamber path or by clamps such as a pressure plate 31 or a pivotable wall section (35, Fig. 2) which press the stack against the opposite chamber wall. In the embodiment (Fig. 5) employing the L-shaped receptacle the stack is fed and compressed in an oblique direction so that clamps are not required. In this embodiment a piston or spring- loaded welding jaw (40, Fig. 5) takes up the space occupied by the leading roller (45) of the folding device when the latter is located beneath the stack undersurface. The plunger 20, crosshead 23, jaw 3 may be pneumatically or hydraulically actuated.

Each conveyer comprises a pair of helically wound spring wire cord bands 5, 6 supported side-by-side so that the bottles may be cradled between them. The burner 18 is fixed on an arm formed by plates 19 which is pivoted at one end 20 and has an adjusting screw 21 at its other end by which it may be rocked about its pivot to adjust the position of the burner vertically. If the adjustment is substantial, the pulleys carrying the cord bands 5, 6 may be adjusted laterally to ensure that cylindrical bottles still pass coaxially through the burner.
