Title: Improvements in fibrous articles and process of and apparatus for making same
IPC: D21J7/00
Filed: 1930-07-23
Abstract: 352,275. Making building - blocks &c. by moulding pulp. BROOKES, N. E., 5, Chancery Lane, London. -(Bemis Industries, Inc.; 40, Central Street, Boston, U.S.A.) July 23, 1930, No. 22235. [Class 87 (ii).] Articles such as bricks are manufactured from fibrous pulp. The pump 91 delivers the pulp from the reservoir 90 to the gravity - distributing tank 95 when the short-circuiting byepass valve 97 is closed. The tank 95 communicates with the perforated rotating cores 50 which pass through the mould and deliver the pulp thereto. A further supply of pulp is delivered to the lower ends of the cores 50 to regulate the distribution. Suction is applied by the pump 81 through the water trap 80 to the mould casing, whereby the solid matter is caused to adhere to the perforated walls 32 of the mould and the liquid is drawn through to the water trap. Air is drawn through the partly consolidated material to assist in removing the remaining water. This is effected by the automatic emptying of the gravity tank 95 through the valve 97 as soon as the mould is fully charged, and the resultant opening of the upper ends of the cores 50 to the atmosphere. The system of working the lower pulp supply and the subsequent air supply to this system are described, also means for draining this system into the tank 80. The mould comprises four perforated walls, three of which are hinged together at 18, 19 while the fourth, 15, is secured in position by the tie-rod 27 and wedge 28. The walls are braced by vertical angle irons 21 at each corner connected by horizontal angle irons 24 and tie rods 31. Linings of finely perforated material 32 are provided all round the walls. In the illustrated form two moulds are used in a single casing, bridge bars 33 connecting them together. The motor 70 which drives the stirring- apparatus 99 in the pulp reservoir also rotates the members 50. The machine thus described manufactures a building-block with a single central hole and a semicircular recess at each end, but a slightly modified machine is described for making blocks with several cored holes. The moulded articles are raised by tackle 99d.

Title: Improvements in or relating to machines for washing minerals, ores, and the like solid materials
IPC: B03B5/56
Filed: 1946-07-29
Abstract: 615.149. Washing granular materials. RATCLIFFE, A., TALBOT, G. W., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. July 29, 1946, No. 22536. [Class 82(ii)] In a machine for washing minerals &c. of the type in which a gyratory motion is imparted to the material at right angles to its line of travel through the machine, washing trough or troughs 1 are resiliently supported independently of the rotating shaft 16 which imparts the gyratory motion to the trough(s) (in the example shown through the agency of the plates 4, rods 7, springs 9 and framework 11, 12), the said shaft being supported by bearings connected to the trough(s) and preferably mounted in a cylindrical housing 14. The shaft 16 is driven through a flexible coupling 18, or a rope drive, by a motor 19 mounted on the framework 12, or the motor may be mounted on the trough(s); the gyratory motion is obtained either by locating the bearings 15 on eccentric journals on the shaft 16 or preferably by offsetting the centre of gravity of the shaft as at 17 and using concentric jouirnals. In operation, solid material and liquid are fed at hoppers 3, and due to the eccentric loading of the rotating shaft 17 the whole suspended system is subjected to a gyratory motion at right angles to the axes of the troughs. Liquid and dross leave the troughs through apertures 20, the washed material being discharged over sills 2.

Title: Improvements in or relating to voltage-dependent capacitors
IPC: H01L29/92
Filed: 1959-07-01
Abstract: 886,637. Semi-conductor devices. SIEMENS & HALSKE A.G. July 1, 1959 [July 2, 1958], No. 22634/59. Class 37. In a voltage - dependent capacitor of the type including a PN junction the cross-sectional area of at least one of the semi-conductor zones adjacent the junction decreases continuously or in a stepwise manner. Thus as the space charge region is expanded by the operating voltage the capacity is further reduced by the decrease in area of the material. Fig. 1 shows a junction consisting of weakly-N-type material 1 which decreases uniformly in area in a direction perpendicular to the junction. The P-type material 2 is more strongly doped. The effect of the weakly doped N region is to increase the expansion of the space charge zone. Fig. 2 shows a construction in which the cross-sectional area of the N-type material 5 is reduced in a step-wise fashion. Layer 7 is P-type and is formed by alloying an acceptor material into the layer 5.
Patent GB-751570-A (GB)
Title: 4-amino-phthalimide-5-sulphonic acid
IPC: C07D209/48
Filed: 1954-08-04
Abstract: The invention comprises 4-amino-phthalimide-5-sulphonic acid and the sodium salt thereof.  4 - Amino - phthalimide - 5 - sulphonic acid is prepared by sulphonating 4-amino-phthalimide with concentrated sulphuric acid, monohydrate, oleum or chlorsulphonic acid and recovering 4-amino-phthalimide-5-sulphonic acid from the mixture. Preferably 4-amino-phthalimide is dissolved in an inert organic solvent, e.g. nitrobenzene, o-dichlorobenzene or tri-chlorobenzene and the sulphonating agent is added to the solution.  The reaction is preferably carried out at elevated temperature. 4-Amino-phthalimide-5-sulphonic acid precipitates as an insoluble internal salt which may be converted into the sodium salt.  In the example chlorosulphonic acid is dropped into a suspension of 4-amino-phthalimide in nitrobenzene at elevated temperature.  The desired product is obtained by filtration or by evaporation of the solvent.  The crude product is suspended in cold water and neutralized with sodium carbonate with the addition of sodium chloride when the sodium salt precipitates. Alternatively the suspension of the internal salt may be added to ice water and the solution may be neutralized with concentrated ammonia.  After heating the aqueous layer is separated and the sodium salt is precipitated by addition of sodium chloride. 4-Amino-phthalimide may be removed from the product by heating the salt with pyridine or acetone.  The product may be diazotized or converted to the acylamino derivatives. 4-Amino-phthalimide is obtained by nitrating phthalimide and reducing the resulting 4-nitro-phthalimide.

Title: Change-ratio gearing
IPC: F16H61/02
Filed: 1961-06-26
Abstract: 937,469. Change-speed gear and control. FAIRCHILD STRATOS CORPORATION. June 26, 1961 [July 6, 1960], No. 22981/61. Class 80 (2). [Also in Groups XXVI and XXVII] A two-ratio gear in which ratio shift is effected by reversal of the direction of torque through the gearing comprises planetary gearing 16 having a ring gear 36 stationed for one direction of drive by a sprag-type one-way detent 40 but allowed to rotate on torque reversal against the resistance of a servo brake-piston 50 through which oil passes to engaged friction surfaces, thereby allowed to slip so that restrained rotation of the ring gear is permitted. In the form shown, a gasturbine 19 in an aeroplane normally drives through the gearing 16 to an axial flow compressor 10 supplying compressed air to the aeroplane cabin, but when the gas turbine is inoperative, compressed air may be fed to the compressor which then acts as a motor and drives back through the gearing at a different ratio to start the gas turbine. The engine shaft 18 carries planet pinions 26 meshing the ring gear 36 and also meshing a sun gear 32 driving the compressor 10, which in turn drives an oil pump 66 feeding pipes 72, 96. A drag-coupling 102 actuated by rotation of the ring gear 36 is connected by a link 100 to a two-position pressure relief valve 80. When the compressor 10 is used as an engine starter motor, the dragcoupling 102 acts to condition the valve 80 to maintain a high pressure in the pipes 72, 96, thus engaging the brake to restrain rotation of the ring gear 36. Pressure in the pipe 72 is fed through a pipe 98 to a resonant nozzle 108 normally lined-up with a venting port 112. As the speed of rotation of the motor-acting compressor 10 increases, the resonant nozzle 108 ultimately begins to oscillate back-andforth as the natural frequency of the compressor &c. is reached, so that free flow of the oil to the venting port 112 is restricted. Increased pressure is therefore supplied to the brake servo 50, which applies the ring gear brake more firmly and tends to slow down the speed of rotation of the motor-acting compressor 10. Oil vented through the port 112 flows through a centrifugally acting valve 120 in the engine shaft which tends to close with increasing engine speed, thus still further increasing the brake engaging pressure. On starting the gas turbine 19, reversal of torque through the gearing 16 acts upon the dragcoupling 102 to so condition the valve 80 that a low pressure only is maintained in the pipes 72, 96, this pressure being fed to a lubricating pipe 74.
