Abstract: 1341783 Biological purification DRAVO CORP 6 Jan 1971 [12 Jan 1970] 570/71 Heading C1C [Also in Divisions B1-B2] Liquid discharged from settling stage 8 of a sewage treatment plant is filtered downwards through a bed 19 of sand or ceramic particles of 1-6 mm. major dia., preferably 1-3 mm. and predominantly within 1 mm. dia. of one another, the bed being supported by false floor 20 to the space under which air and filtrate are periodically delivered to backwash the bed, the backwash liquid than flowing over weir 37 (Fig. 5) to reservoir 39 (Fig. 1). The various treatment stages shown in Fig. 1 are all performed in a central vessel 8 and a series of tanks formed by dividing an annular vessel enclosing tank 8 with radial walls (Fig. 2, not shown). The two filters shown in Fig. 5 occupy one of the tanks, divided by wall 3b, and are used alternately. Liquid flowing over weir 10 of central vessel 8 is delivered by channel 23 through one of valves (24) to the filter in use, and filtrate passes through valved outlet (27) to a chlorination tank 28. Some liquid from tank 28 is discharged, while a proportion is pumped to backwash the filter which is out of use. During backwashing the space under floor 20 is first supplied with air by compressor 30, then with air and filtrate together; pressures and flow rates are exemplified. Tank 39 evens out the flow of backwash liquid which is pumped back to primary contact tank 6, where it mixes with incoming raw sewage and recycled sludge from tank 14. Settled sludge from vessel 8 is scraped into sump 13 and delivered by air lift pump 15 to tank 14 where it is aerated. Sludge not recycled to tank 6 is delivered to aerobic digester tank 16.

Title: Improvements in, or connected with, electric motors
IPC: B66C13/24
Filed: 1923-01-10
Abstract: 213,692. Scott, W. H. Jan. 10, 1923. Motors, controlling. - In a series motor for winches, cranes, or the like which at times is caused to run at reduced speed by means of a series resistance which absorbs part of the line voltage, a non-inductive diverting resistance is used across the series winding or part of the series winding to keep an electric brake in a floating condition of application. Fig. 1 shows the use of a diverter R across the brake hold-off coil for this purpose. With the controller on step 1 the brake coil is shunted and the resistance inserted in the circuit of the motor which thus floats on the brake at a reduced speed. At step 2 the resistance is still in, but the diverter is disconnected and at step 3 the resistance is short-circuited, the diverter still being open, so that the brake is held off fully during steps 2 and 3. In place of being connected across the whole brake magnet coil, the diverter may be across a part only, the remaining part being shortcircuited during the floating period. In Fig. 3, a diverter R<3> is permanently connected across the brakes hold-off coil and the change from floating to hold-off of the brake is made by connecting in a shunt coil S on the magnet which in steps 2 and 3 assists the series coil, step 1 giving the floating connection, as in Fig. 1, i.e. with the series hold-off coil only in action.

Title: Improvements in or relating to the dehydration of castor oil
IPC: C09F5/06
Filed: 1951-01-12
Abstract: Castor oil is dehydrated by adding a solution of a dehydration catalyst to castor oil which has been preheated to above 450 DEG F. Many catalyst are specified.  Those soluble in the oil, e.g. sulphonic, sulphuric and phosphoric acids and diethyl and dimethyl sulphate, may be dissolved in a small quantity of oil, e.g. 5-15 per cent of the total, and added to the bulk of hot oil.  Those insoluble in the oil, e.g. sodium bisulphate, may be added to the hot oil aqueous solution.  Solution in oil is preferred to solution in water. Preferably the solution contains 0.1-2 per cent of catalyst based on the oil.  Dehydration temperatures mentioned are about 500-560 DEG F, preferably about 520-560 DEG F. Reaction may be effected in the presence of an inert gas, which may be used for removing water of dehydration.  The latter may also be removed by applying a vacuum. Heating may be effected in a large vessel or by passing the oil through a heat-exchange system.  Desirably the catalyst is added portionwise or continuously and the dehydration time is kept as low as possible, e.g. 1-2 hours.  The catalyst solution may itself be preheated, and dehydrated castor oil may be used as solvent. Instantaneous addition of catalyst requires slightly more catalyst. Alkyl phosphites should not be used as catalyst when drying oils are to be made.  Oils of good colour are obtained.  In examples raw castor oil is heated to 550 DEG F. and (1) aqueous sodium bisulphate, (2) a solution of diethyl phosphite in castor oil, (3) phosphorous acid in castor oil and (4) diethyl sulphate in castor oil (whilst passing CO2) are added.  In a further example (4) is repeated under vacuum without CO2.  Illustrations for comparative purposes are provided of similar reactions in which the oil is not preheated and in which the catalyst is added without prior dilution.

Title: Control apparatus for two bidirectional step motors
Inventor: BESSON RENE
IPC: H02P8/40
Filed: 1993-09-02
Abstract: The device includes two driving circuit (C1, C2) each of which includes six power transistors (T11-T16, T21-T26) that are connected in pairs into three parallel circuit branches. A first coil (B11) of one of the motors and a first coil (B21) of the other are, on the one hand, both connected to the junctions of the transistors of one of the branches of one of the driving circuits (C1) and, on the other hand, respectively connected to the junctions of the transistors of the two other branches of this circuit. The same applies for the second coils (B12, B22) of the motors and the other driving circuit (C2). The various transistors are controlled so that the two coils of the same motor simultaneously receive the current pulses which are needed to make it turn but by preventing the simultaneous application of current pulses to a coil from one of the motors and to a coil from the other. This arrangement makes it possible to save four transistors and two output terminals on the integrated circuit used to control the motors.

Abstract: PURPOSE:To facilitate the detection of leakage, if any, from a connection by a methd wherein the connection between a cooling duct and an insulated pipe where leakage may occur from therebetween a is covered with a thin film capsule similr to a rubber balloon. CONSTITUTION:An insulated pipe 12 is connected to a cooling duct nozzle 16 forming part of a cooling duct through a flange 15. An O-ring is used to seal the flange. The flange 15 is covered with a thin film capsule 18, for instance, a rubber balloon, enclosing the flange. In case leakage should occur from the connection, the thin film capsule 18 will expand and explode. The explosion of the capsule 18 can visually be observed through a check window made in the tank. In so doing, accordingly, leakage of the cooling medium in the tank can readily be discovered and the leakage spot can also be made clear.
