Title: Improvements in or relating to paper making machines
IPC: D21F3/04
Filed: 1937-07-26
Abstract: 499,657. Wet presses for paper-making machines. MILLSPAUGH, W. H. July 26, 1937, No. 20598. [Class 96] In a paper-making machine having a wet press beyond the wire cloth 11 comprising two suction press-rolls 1, 2, a plain intermediate roll 3 arranged to coact with the two suction rolls and two endless press felts 5, 6 each extending over and around one of the suction press-rolls, the axes of the suction rolls 1, 2 are arranged below the axis of the plain roll and the stationary suction boxes 1a, 2a within the suction rolls are so arranged in relation to the two bites between the two suction rolls and the plain roll that water expressed from the wet web of paper 7 and into and through the felts will be drawn into and from the suction boxes. The two felts 5, 6 may be of different texture. The two felts may be replaced by a single endless felt extending over each of the suction rolls and below the plain roll. The plain roll may be carried by pivoted arms 4 so as to press freely against the suction rolls. The axes of the two suction rolls may be in the same horizontal plane or the axis of the second suction roll may be lower than that of the first suction roll. One or more of the rolls may be mounted in laterally adjustable bearings so that the rolls may be moved radially relatively to one another. All the rolls may be positively driven or two rolls only may be positively driven, the third roll being driven by friction contact with the other rolls ; the peripheral speed of the rolls may be synchronized for example by the means described in Specification 458,756 or 458,757, or by means of multiple belts driven by a series of expanding cones mounted on the rotating shaft of a driven roll. The wet web of paper may be transferred from the wire cloth 11 to the felt 5 of the wet press by means of a felt 10, Fig. 4, and suction roll 8 located after but adjacent the suction box 9a of the couch roll 9 as described in Specification 458,758 ; the two felts 5, 10 with the web of paper therebetween preferably pass through the bite of a preliminary pair of press rolls 12, 13, the lower one 13 being a suction roll and the upper one 12 being plain roll.

Abstract: 222,275. Tunmer, R. F. Aug. 14,1923. Crystal detectors. - A holder for a crystal D comprises a cup A<1> having corrugations &c. on its inner wall and a spring controlled plunger B<1> carrying a plate B<2> with a serrated or otherwise roughened surface B. The crystal is thus held firmly in position, and multiple electrical contact with the crystal is ensured. The opening a<1> in the cup through which the plunger B<1> passes is larger than the stem of the plunger so that the latter is allowed a limited rocking movement to allow the plate B<2> to accommodate, itself to the surface of the crystal. Or the plate B<2> may be mounted so that it may rock on the plunger B'. The spring C on the plunger is preferably conical so that the convolutions may lie within each other when the spring is compressed.

Abstract: 632,704. Bottling, stoppering, and capsuling machines. CHELLE, P. L. Aug. 10, 1945, Nos. 20621 and 20622. Convention dates, June 24, 1943 and May 26, 1944. [Class 125(ii)] Apparatus for filling, stoppering, capsuling and labelling bottles or the like, comprising filling, stoppering, capsuling and labelling machines and a bottle conveyer mounted on a common frame containing common drive means for the various devices, the bottles being passed one by one by the conveyer into the machines, is characterized by the conveyer being in the form of an endless chain, the active stretches of which are situated in a common horizontal plane, and by the common frame comprising at the top, under the conveyer, a tray for receiving liquid spilt from the filling machine or from broken bottles. In the form shown in Fig. 1, the filling machine T, the stoppering machine B and the capsuling machine C are mounted on a table having upturned edges 13, on a frame 2, fixed to the base 1, while the labelling machine E is mounted on a table on a frame 3, slidable on the base 1. The conveyer 9 runs around a sprocket 14 mounted on the frame 3, and a driving sprocket 15, fixed to the tank of the filling- machine, and rotating intermittently therewith. The conveyer is tensioned by nuts 10, rotation of which causes movement of the frame 3 relative to the frame 2. The machines are driven from an electric motor 5 through shafts 4 and 6, geared together by gears 7 and 8, one of which has wide teeth to allow movement of the frame 3 without disengagement of the gears. In the embodiment shown in Fig. 3, all the machines are mounted on a table carried by a common frame 2, and a safety device for the conveyer 9 is provided, consisting of a spring-loaded mounting for the sprocket 14; the adjustment of the tension of the conveyer is by two sprockets 40, one contacting either stretch thereof,. the separation of the sprockets being adjustable by a spindle 43 with reversed threads, running in the blocks 39 upon which they are mounted. The tank of the filling-machine T is driven intermittently from a cam having a double groove, part of which is helical and the remainder circular, which engages rollers 29 carried by a disc 27 fixed to the shaft 22 of the tank. Specification 626,168, [Group XV], and French Specifications 736,592, 795,081 and 863,238, are referred to.

In order that the presence of a container component, e.g. a can end, differing from a predetermined kind can be detected photo-electrically the component is marked according to a code with a substantially clear and colourless medium containing a luminescent substance. In the embodiment described the markings take the form of parallel lines or of concentric circles, the spacing of the lines or circles being indicative of the product or of the decoration on the component, and are caused to fluoresce under the action of ultra-violet light. In one embodiment two photo-cells are used in conjunction with a movable apertured plate. If the lines appear under the apertures both cells give an output which is fed via an amplifier and pulse shaper to a coincidence gate. If an undesired component is viewed there will not be coincidence, and a visual warning and automatic ejection device are operated. In a second embodiment only one cell is used, the time taken for two markings on the steadily moving component to pass the cell being indicative of the type of component viewed.
