Title: Improvements in the machines for the production of papers, cardboards or other sheets
Inventor: PIERRE LEJEUNE
IPC: D21F1/06
Filed: 1962-09-14
Abstract: 953, 635. Regulating flow and consistency of paper pulp. ETABLISSEMENTS NEYRPIC (ATELIERS NEYRET-BEYLIER & PICCARDPICTET), and SOC. GRENOBLOISE D'ETUDES ET D'APPLICATIONS HYDRAULICS SOGREAH. Sept. 14, 1962 [Sept. 15, 1961; Aug. 9, 1962], No. 35171/62. Heading D2A. [Also in Division G3] In a pulp feeding circuit pulp is pumped in a closed circuit having.an inlet duct and a discharge orifice, the pulp which by-passes the discharge orifice being returned via an overflow unit, a condition of operation of which automatically controls the supply of pulp to the inlet duct. In Fig. 1 a pump 2 supplies pulp through ducts 3, 5 to a paper or cardboard-forming discharge orifice 9 and the increase in width from the beginning of duct 3, which is of circular section, to duct 5, which is of rectangular section, is taken care of by a spreader box 4 which may have one or two projections such as 15 to produce uniformity of flow across the width of duct 5. The pulp which passes discharge orifice 9 enters a duct 6 divided by vertical baffles to reduce turbulence and then overflows into a duct 7 leading to the inlet of pump 2. Changes in the level in duct 7, detected electrically at 27, serve to control a servomotor 25 adjusting the supply of pulp through an inlet duct 8 so as to compensate for varying rates of operation of the paper making machine and permit pump 2 to maintain a constant flow. The rate of flow through discharge orifice 9 may be controlled by air pressure or suction applied above the level of the pulp by a pump 20 and adjusted manually and automatically by valves 23 and 24 respectively, Figs. 2-8 (not shown) illustrate suitable shapes for the ducts, baffles and spreader box. The levels of pulp in ducts 6 and 7 may be substantially equal and well above the division between the ducts. In another arrangement the upper portion of the division between ducts 6, 7 is pivoted about a horizontal axis to permit adjustment of the rate of discharge from orifice 9 without the need for pump 20.

Abstract: 410,048. Hydraulic machines. GIOVANNONI, J. A., 10, Rue de l'H¶pital Militaire, Lille, France. Dec. 15, 1933, No. 35386. Convention date, Dec. 21,1932. [Class 69 (ii).] Means for controlling the flow of liquid to and from the cylinder of an hydraulic jack or like lifting-device comprises a series of coaxial chambers fitted with ball or other suctionactuated valves arranged in the following manner in order to avoid the use of a separate return passage for the liquid and a separate check valve for braking the descent of the load. An actuating-lever A is pivoted at B to a pump plunger 1, below the cylinder 3 of which are arranged chambers 5, 4, 8, 9, Figs. 1 and 2, fitted with suction and pressure-actuated ball valves 14, 13, 15. The cylinder 3 is connected by a duct 2 to the chamber 4, and the chamber 5 is connected by a duct 6 to a supply reservoir 7, and the chamber 9 by a duct 10 to the lower end of the jack cylinder 11, fitted with a piston F. When the plunger 1 is raised, liquid flows from the reservoir 7 through the duct 6, the chambers 5, 4, and the duct 2 into the cylinder 3, the valve 14 being opened and the valve 13 closed. When the plunger 1 is depressed, the valve 14 is closed and the valve 13 opened, and liquid is forced from the cylinder 3 through the duct 2, chambers 4, 8, 9, and duct 10 to the jack cylinder 11. The load is lowered by an additional depression of the piston 1, whereby a sliding rod 16 is depressed by the piston to open the valve 14, thus re-establishing communication from the jack cylinder 11 through the chambers and duct 6 to the reservoir 7. On a predetermined intensity of the return flow, the valve 15 is closed, and the liquid flows through restricted passages 18 in the valve seat to effect a braking action. The throttling or braking action is assisted by an enlargement 17 on the rod 16 opposite the duct 6, the chamber 5 being tapered if desired to increase the throttling action.

Filed: 1975-08-30
Abstract: 1513802 Selective signalling FERRANTI Ltd 31 Aug 1976 [30 Aug 1975] 35857/75 Heading G4H In a communication system for providing time-division communication over a single channel between a central control unit and a plurality of controlled units, respective control words can be sent in both directions during halfcycles of one polarity of a periodic signal and data can be sent from the controlled units to the central unit during half-cycles of the other polarity. At a petrol filling station, a central kiosk controls a plurality of remote locations (blendertype petrol pumps) using a signal line and a clock pulse line linking the kiosk to all the remote locations in a loop. A counter at each remote location counts the clock pulses, a respective count defining a time slot relating to the remote location on the signal line. The sequence of time slots starts with a sync. slot to synchronize the counters. The slot for a remote location consists of 3 bits for sending "control" commands to the kiosk, a "1" bit, 3 bits for sending control commands from the kiosk, and a final "1" bit, each bit being sent during a positive half-cycle of the clock pulse sequence. One command sent from the kiosk can cause the remote location to send a data message to the kiosk twice, on the signal line. This message consists of a start bit, bits indicating grade of petrol, bits identifying the remote location, and price and volume information in BCD form, each bit being sent during a negative half-cycle of the clock pulse sequence. The data message is compared with its repeat at the central kiosk to enable print-out if equal, the message also being displayed.
