Title: Method of and apparatus for pressing molded pulp articles
IPC: D21J3/00
Filed: 1954-05-11
Abstract: 752,258. Moulding pulp articles. TRIGGS, W. W. (Keyes Fibre Co.), May 11, 1954, No. 13730/54. Class 87(2) Egg cartons are made from a slurry of fibre and water by shaping them on die formers by suction, drying them and then pressing them between dies, in the presence of heat and moisture to an extent only sufficient to remove the warpage and distortion of the drying. The articles are first moulded from pulp by apparatus as shown diagrammatically in Fig. 1, in which 13 represents a tank containing pulp through which female die formers 10 on the ends of hollow arms 11 are rotated step-by-step, pulp articles being formed on them by suction. A male die former 14 oscillates in synchronism with the movement of the arms 11, at the end of a hollow arm 15, and transfers the articles to a conveyer 19 which carries it to a succession of conveyers 20, 22, 23 which take it through a drier 21 and a gate 41 to the press. The dies 24, 25 of the press, which may be steam-heated, are designed to restore the dried article to its original moulded shape and to give it a smooth finish, besides, if desired, impressing extra designs on it. Water or stiffening, colouring or other materials may be sprayed on the article before it is pressed. The die 25 is raised and lowered by a hydraulic piston and cylinder 29, 29<1> controlled by a valve 30. A motor-driven camshaft 35 reciprocates a valve stem 40, through a cam and lever 36, 38, and causes hydraulic fluid to be admitted alternately to the top and bottom of the cylinder 29<1> through pipes 31, 32. The gate 41 ensures that the dried articles are fed singly in time with the opening and closing of the press and comprises a rocking member with depending portions 42, 43 operated from the camshaft 35 through a cam 50, lever 48, and links 46, 45a. The pressed article is delivered on a transfer device 51 which deposits it on a conveyer 52. The device 51 is mounted on a carriage 53 which is reciprocated in guides 56 by the oscillation of a lever 57 about a pivot 59 carried by the operation of a hydraulic piston and cylinder 61, 62 controlled by a valve 66 which is cam-operated, similarly to the valve 30, from the camshaft 35, in synchronism with the die 25. As the carriage 53 approaches its outer position a slotted yoke 73, fixed to a pivot 72 which connects the carriage 53 and the transfer device 51, embraces a stationary pin 74 and the device 51 is thus caused to tilt and deposit the pressed article on the conveyer 52. Vacuum and/or compressed air may be supplied to the dies through a pipe 34, timed by vacuum mechanism' to co-operate with the movement of the dies so that the article is transferred to the male upper die as the press opens and dislodged therefrom for delivery in the fully open position. The reshaping press may be adapted for use with existing pulp moulding machines.

Title: Improvements in and relating to electrical apparatus for the measurement of pressurein vacuum systems
IPC: G01L21/00
Filed: 1943-08-28
Abstract: 566,470. Determining physical qualities of materials ; resistance meters ; thermionic ammeters and voltmeters. ROLLIN, B. V. Aug. 28, 1943, No. 14086. [Class 37] An ionisation pressure gauge for the measurement of pressure in high vacuum systems comprises a thermionic valve connected to the system, the vacuum of which is to be measured. A positive potential is applied to the grid and a negative potential to the anode. Residual gas atoms in the valve, while connected up to the vacuum to be measured, are ionised and positively charged by collision with electrons emitted by the cathode ; the positive ions collect at the anode, giving rise to a positive ion current which is a measure of the pressure. The ionisation gauge is connected to an amplifier, both being connected to an A.C. supply by connections adapted to allow only unidirectional currents to flow through the apparatus so that no additional rectifier is required. As shown in Fig. 1, the gauge a is connected to the amplifier b by means of a switch c between the anode of the gauge and the grid of the amplifier. The electrodes of the two valves a, bare connected to an A.C. supply d1, d2 by high resistances R1, R2, R3, R4, R5. The ion current is measured by an A.C. or D.C. instrument e and the electron emission current by an instrument f. The anode of the gauge a is negative with respect to its cathode because of the potential drop in R3 due to the emission current. The ion current flowing through R5 changes the grid potential of the amplifier b, causing a corresponding change in its anode current. Both the gauge and the amplifier operate only during the half-cycles when d1 is positive with respect to d2. A single instrument may be inserted between the points g, h. By turning off the gauge a reading is obtained depending on the potential drop in R2. The cathode of the gauge is then heated until emission starts and with the switch c open, the reading falls on account of the potential fall in R1, the difference of the two readings giving a measure of the emission current, which may be adjusted until a zero reading is obtained. On closing the switch c the ion current flows through R5 causing the potential drop across R2 to change and the reading to increase. The increase is a measure of the ion current and therefore of the pressure in the gauge. Alternatively, the instrument may be connected between the points i, j. The measuring instrument may be a milliammeter or voltmeter, a cathode-ray tube, or a " magic eye," which avoids the use of an amplifying valve other than the " magic eye " itself. A device for keeping the emission current of the gauge constant is shown in Fig. 5, in which a gas-filled relay b is incorporated. Increase of the emission current in the gauge a increases the potential drop in a resistance R3 and causes the grid of the relay to become more negative with respect to its cathode so that current passes through it during a smaller fraction of the cycle and the filament heating of the gauge is reduced.
