Abstract: In a method for measuring the volume of a liquid flow through a measuring chamber (2) during a measuring period, a pulse generator (12) is caused to emit a number of pulses corresponding to the volume. In the measurement, the measuring period is divided into a number of measuring intervals. During each measuring interval, the pulses from the pulse generator (12) are detected, each detected pulse is multiplied by a flow correction factor, the corrected pulse values are added to a summation variable, and this summation variable is multiplied by a volume conversion factor for determining the liquid volume. The separate determined liquid volumes are thereafter summed up for all measuring intervals during the measuring period. A measuring apparatus for measuring the volume of a liquid flow through a measuring chamber (2) has a pulse generator (21, 23) for generating a number of pulses corresponding to the volume, has time base means (33) for dividing the measuring period into measuring intervals, memory means (34) for storing one or more correction factors, pulse-correcting computing means (24, 25) for multiplying each detected pulse by said one or more correction factors, adder means (26, 27) for adding the corrected pulse values, and multiplier means (35) for multiplying the added corrected pulse values by a volume conversion factor.

Title: Improved process of impregnating layers of fibrous material with synthetic artificial resin
IPC: D21H17/48
Filed: 1934-01-15
Abstract: A sheet of fibrous material such as paper or fabric of considerable length is impregnated with a preferably aqueous solution of the initial elementary substances of a synthetic resin, whereupon, prior to drying, the sheet is wound into a roll in order to avoid vaporization of volatile initial substances during the condensation which is effected to such an extent that in the subsequent drying and final heating, vaporizable initial substances are no longer present. Condensation may be effected at room temperature or by heating. suitable synthetic resins are condensation products of formaldehyde or furfural with phenol, cresol, urea or thiourea.  Examples describe impregnating paper with a solution of cresol, formalin and hexamethylenetetramine, winding on a cylinder to form a roll, heating at 75 DEG  C. for 24 hours to effect the condensation and drying by leading the length of paper through a heated chamber or in vacuo at a low p  temperature.  Tubes may be made by winding the dried intermediate product on a core and heating, if desired, under pressure. Compound sheets may be formed by compressing a plurality of layers at high temperature and pressure.  Moulded articles may be made by dividing the dried intermediate product into small pieces and forming by heat and pressure.  The Specification as open to inspection under Sect. 91 describes also drying an impregnated breadth of paper by leading it through a closed furnace which fits the paper so exactly that no volatile substances escape.  This subject-matter does not appear in the Specification as accepted.

A metal extrusion press has two die-sets 15, 115, for alternate use during an extrusion cycle, each of the sets being separately retractable from the press through a tunnel 17 in the platen 10, and two outside stations 16, 116, for auxiliary operations, e.g. discard removal, supported on or built into the platen at opposite sides of the longitudinal axis X, X of the press. When in its working position a die-set is secured in the platen by hydraulically-operated plates 22. The die-set is transferred after retraction from its working position opposite a billet container 13, Fig. 1, by lateral movements of a slide 20 which moves it to or from the station 16, the other die-set concurrently being moved from or to the second station 116 by a slide 120. Run-out tables 24, 124, secured together by a cross-member 26 are pivoted at their converging point 27 on the axis X, X to swing respectively with the slides 20 and 120 to stations 16 or 116 as the extruded article is released from the platen 10. Fig. 2 shows the detail of station 16, including an hydraulically-operated punch 28 for shearing the discard D from an extruded tube A in the die-set 15; a stripper-ring 34 removes the discard from the punch on its return stroke within the platen 10. The transverse movement of the slide 20 into the station 16 after its withdrawal by a rack-and-pinion 35 from the working position in the platen tunnel 17 is effected by swinging by powered means the run-out table 24 on which it is supported after withdrawal, a C-shaped support plate 32 accepting the work and die-set in a recess facing towards the axis X, X. The movement of the slide on its table by the drive 35 is so controlled, e.g. by limit switches that the die-set 15, when aligned with the axis Y, Y, Fig. 1, is through a boss 21, in axial engagement with the support plate 32. Station 116 is similarly equipped. In a modification, parallel run-out tables and slides may be moved transversely opposite their working and ancillary positions in place of the pivoted converging tables and slides described.
