IPC: D21D1/30
Filed: 1947-08-07
Abstract: 647,905. Preparation of paper pulp. PRICE BROS. & CO., Ltd. Aug. 7, 1947, Nos. 21624 and 21625. Convention dates, June 6, 1946 and July 8, 1946. [Class 96] Paper pulp is screened into different fibre sizes, or washed free of soluble matter and ink &c., by simultaneously rolling and pressing the pulp, in the presence of an aqueous liquid, across and between opposed plates 1 and 2 at least one of which is pierced by holes &c. 16. Pulp may be fed in at 12 and discharged at 13. Liquid may be fed to the pulp during rolling and may contain detergents or bleaches. The clearance between the plates may be varied cyclically as by moving plate 2 to and from plate 1 and the plates may be moved relatively across each other, e.g. in planes perpendicular to the to-and-fro motion. One plate, e.g. plate 2 may be gyrated so that all points therein move in separate paths, e.g. equal circles. The opposed surfaces may be toothed, The holes 16 may be backed by channels 17 18, 19, 23 and 24 connected to pipes 20, 21, 22, 25 and 26 enabling different liquids to be fed to the pulp and drained therefrom. Liquid may be fed in through holes in one plate and drained off through holes in the other. Its rate of flow may be regulated. Rolling may be continued until a desired fraction of the finer constituents of the pulp or the ink &c. or the soluble matter has been carried off in the exhaust liquid. Pulp may be thickened by continually increasing the pressure exerted on it by the plates. Partially disintegrated waste paper can be completely repulped by agitation in the apparatus.

Title: Improvements in or relating to control devices or valves for vacuum systems, and vacuum control systems for vacuum operated airplane instruments
IPC: B64D13/04
Filed: 1943-12-24
Abstract: 599,189. Regulating air compressors. PESCO PRODUCTS CO. Dec. 24,1943, No. 21642. Convention date, Dec. 12, 1942. [Class 8 (i)] [Also in Group XXIX] A control device 16 for vacuum systems, especially those used to operate aircraft instruments comprises a valve 44 which is normally closed to cut off the system from a source of outside pressure and pressure responsive means such as the diaphragm 54 subject to a second source of pressure, such as aircraft cabin pressure, for unseating the valve, and admitting outside pressure to the system. As shown in Figs. 1 and 2, the device 16 comprises a cylindrical housing 30 with a connection 22 to a vacuum pump 20, a second connection 18 to a vacuum-operated instrument within the air. craft cabin 12, a third connection 28 to atmosphere through a filter 26 and a fourth connection 24 to the pressure in the cabin 12. The base of the housing 30 is closed by a base 34 having an integral spindle guide 38. The guide 38 has a bearing bush 42 and is provided with a vent hole 41. The valve disc 44 is normally forced to its seating 68 by a spring 70. The valve has an integral spindle 39 clamped at its upper end to a diaphragm 54 of rubberised fabric or neoprene clamped at its periphery to the housing 30 by a cover 35. Ports 50 in a spider 60 place the diaphragm in communioation with the atmospheric connection 28. In operation, the valve 44 remains seated until the vacuum in the system exceeds a predetermined amount when it opens to restore the vacuum to normal. As the aircraft ascends, the atmospheric pressure decreases whilst the pressure in the cabin is maintained by a supercharger so that the pressure on the diaphragm opens the valve 44 and relieves the load on the pump 20. At high altitudes, say 40,000 ft., with the valve 44 fully open and the pump 20 completely unloaded, the vacuum created in the system may exceed the predetermined amount and adversely affect the instrument. To prevent this, a second valve may be inserted in the connection 18 to admit some of the pressure from the cabin when the vacuum exceeds the predetermined amount.

Title: Control for hydraulic jack circuits
IPC: F15B13/02
Filed: 1959-06-29
Abstract: 863,701. Hydraulic apparatus. CATERPILLAR TRACTOR CO. June 29, 1959 [April 3, 1959], No. 22176/59. Class 69 (2). [Also in Group XXI] The lowering of an implement, such as the bulldozer 10 of a tractor 13, by a jack 14 is effected rapidly by the provision of a passage 24 which is between the intake and exhaust passages 19, 20 of the jack and has one or more check valves 26, 32 adapted to open upon the event of the pressure in the exhaust passage exceeding the pressure in the intake passage. The jack is supplied with liquid pressure from either of the passages 19, 20 which are connected to a reversing valve 18 leading from a pump 17 and sump 21. A housing 22 is interposed in the passages closely adjacent the jack and has passages 23, 24 forming part of the passages 19, 20 respectively. The passage 24 also extends to meet the passage 23 and is provided with the check valves 26, 27. When the bulldozer is being lowered, the pump 17 is connected by the passage 19 to the upper end of the jack. The weight of the bulldozer causes the pressure in the exhaust passages 20, 24 to be higher than in the intake passage to open the check valves 26, 27 and by-pass the fluid from the lower end of the jack to the upper end; a throttle 29 in a normally closed check valve 25 assists in the raising of the pressure in the passage 24. When the bulldozer strikes the ground, the drop in pressure in the passage 20 permits the check valves 26, 32 to close so that the fluid pressure from the pump applies a downward force on the bulldozer. The bulldozer is raised by operation of the valve 18 to connect the pump to the line 20, the pressure from the pump opening the check valve 25 to permit the fluid to flow unrestricted to the lower end of the jack. In other embodiments, the check valve 25 is dispensed with, the throttle being formed in the passage 24 and a single check valve is provided between the intake and exhaust passages.
