Abstract: 332,269. Bowles, E. J., and Molins Machine Co., Ltd. April 15, 1929. Index-type-wheel machines. - A ticket printing and registering machine comprises four type-wheels, one for printing one of a series of fare indications, another for printing one of a further series of fare indications, another for printing the class of ticket, and another for printing the fare stage, and registering means associated with each fare indication on both fare wheels. The class type-wheel 4 is set by rotation of the knob 29, and the fare stage type-wheel 3 is advanced one fare stage by a complete rotation of the knob 29 through the single toothed wheel 32 and spur wheel 33 fixed to wheel 3, the fare stage set being shown on an indicator 34, integral with a spur wheel 36 meshing with a spur wheel 37 integral with the wheel 3, which is observed through an aperture 40. The first fare typewheel 2 is set by longitudinal movement of the shaft 9 through the rack 11 and spur wheel 12 integral with the wheel 2. Rotation of the wheel 2 rotates the shaft 13 carrying cams 13a through the spur wheels 18, 17, sleeve 16<a>, and spiral gears 15 and 14, and sets the fare indicator disc 38 fixed to sleeve 16<a> which is observed through an aperture 39. The cams 13<a> by pressing on levers 44 determine which of the pawls.42 is to be in operative relation with its registering mechanism 10<a> or 10<b>. The second fare type-wheel 5 is set by rotation of the knob 19 carried on a sleeve 19<a> fixed to wheel 5, which is maintained in its operative position by means of a spring-controlled pin 20 which coacts with a series of depressions in the face of a member 21 integral with the sleeve 19<a>. Rotation of the wheel 5 puts one of the cams, determined by the fare selected to be printed, on the shafts 22, 23 into operative relation with its respective registering mechanism through the mutilated spur gears 24 and 25 fixed to member 21, spur wheels 26 and 27, 28 and 28b, and 28a and 28c. Rotation of the shaft 9 by means of knob 45 rotates a cam 46, carried by the shaft, which operates the rocking members 43, 43a carrying the pawls 42 for actuating the registering mechanism through a lever 48, having a roller 48a in contact with the cam and carrying a gear segment 48b, and gears 49 and 50. An independent counting unit is actuated on each movement of the member 43 in order to mark a serial number indication on the tickets printed and also register the total number of individual tickets printed. Rotation of the shaft 9 also rotates cam 51 which presses a lever against the action of a spring, which forces the. platen 7 against a ticket inserted in the slot 6 to be printed by the type wheels and ink ribbon 8. The rim of each wheel of all the counting units is furnished with type numbers so that a way card can be printed with their readings after the fare class and stage printing wheels have been rotated to a neutral position.

Abstract: 962,410. Expressing liquid from or adding liquid to paper pulp. BILLERUDS A.B., and SVENSKA CELLULOSA A.B. Aug. 30, 1962 [Sept. 15, 1961], No. 33287/62. Heading D2A. A mass of fibre pulp is made to flow through a passage having perforated side walls under the action of a pressure difference between and applied at the ends of the passage and liquid is expelled from or introduced into the pulp through the perforations in the side walls according to the pressure difference across the walls. The fibre pulp, which must have a minimum concentration of 5% by weight and preferably at least 15%, forms a coherent column of pulp from which liquid may be expelled substantially without loss of fibre through the perforations. Counter pressure means are required at the end of the passage and may be provided by a constriction or bend in the passage, by a conically shaped member disposed at the outlet or by connecting the passage to a pressurised reaction vessel. As shown, filtered pulp of e.g. 15% concentration from a rotary filter 2 is supplied through tube 5 to a screwfeeder 6 and pulp pump 7 which causes a cylindrical column of pulp to flow through a perforated or foraminous strainer tube 8 surrounded by a jacket 9 into which liquid is expelled from the pulp. The discharge of liquid from the pulp is controlled by a valve 11. The concentrated pulp passes to a mixer 14 and is disintegrated therein to pass into a pressurised boiler 16 for digestion with soda solution. In a modification (Fig. 2 not shown) a plurality of strainer tubes each with pulp feeder and pump are connected in series and water for pulp-washing is added to the pulp entering the final stage while the liquid expelled from the strainer tube of that and of each stage is passed to the preceding stage inlet for further washing. In a further modification (Fig. 3 not shown) a plurality of strainer tubes are connected in series to form a tower and water for pulp washing or liquid for chemical treatment may be introduced through the perforations of one strainer tube and expelled through those of the following tube. In a further modification (Fig. 4 not shown) high pressure washing water is introduced at the point where the pulp is disintegrated to flow counter current to the pulp column the water being extracted through the strainer tube.
