Title: Improvements in or relating to spools with variable diameters, particularly for a thread of artificial silk
IPC: B65H75/24
Filed: 1929-01-14
Abstract: 304,203. Schoenfeld, M. Jan. 16, 1928, [Convention date]. Spools.-In spools of variable diameter, particularly adapted for the wet treatment of artificial silk threads, radially movable longitudinal parts of the periphery when moved inwardly provide in the end portions of the spool a continuous cover extending beyond the wound up goods and so prevent the liquid used from flowing through the side of the spool. A cylinder 1, slotted at 2, has its slots completely covered by longitudinal parts 3 having a row of apertures 5 for the passage of the liquid. Pins 4 are used to effect radial displacement of the parts which are pushed out during winding and occupy an inward position against the cylinder 1 during the liquid treatment. The slots may be dispensed with, the cylinder 1 being recessed to receive the parts 3, Fig. 3, apertures being then provided in the recesses and parts 3 and also in the parts of the cylinder 1 between the recesses. The recesses may be short stamped depressions at the ends of the cylinder 1. As shown in Fig. 7, the parts 3 have extensions 3<1> which in both the retracted and outermost positions form a continuous convex surface. In this latter arrangement ring shaped end parts 1 are rigidly connected by four bars 8. Ring shaped end pieces may be used and connected together by bars in which the pins 4 carrying the parts 3 are mounted, the parts 3 in their inward position forming a continuous cover in themselves. Specification No. 296,634 is referred to.

Title: Process for the preparation of base-exchange materials
IPC: C01B33/46
Filed: 1933-01-19
Abstract: In the production of base-exchanging substances by the treatment of hydrated aluminium silicates of naturally or artificially produced indurated character first with dilute acid and then with dilute caustic alkali, both treatments are affected at atmospheric pressure, and the treatment with alkali takes place in the cold or at temperatures not exceeding about 30 DEG  C. Fireclays having a composition approximating to that of kaolin may be employed, and be subjected to calcination at 500--600 DEG  C. prior to or following the acid treatment which may take at elevated temperatures. Sulphuric acid or an acid solution of an aluminium salt may be used for the acid treatment, and the alkali may be caustic soda, caustic potash, or ammonia.  The material is thoroughly washed after each treatment, and caustic alkali containing alkali silicate which is obtained by the alkali treatment may be used in making up caustic alkali for subsequent operations.  If the treated material, after use in the softening of water, has lost alkali and base-exchange efficiency, it may be restored by treatment with caustic alkali as above described.

Patent GB-360277-A (GB)
IPC: C10G17/10
Filed: 1931-01-20
Abstract: The residues obtained when mineral oils containing naphthenic acids are distilled in presence of alkali are treated preferably after dilution with liquid hydrocarbon, with concentrated sulphuric acid to liberate the acids and recover contained oil. For example, the residue of the distillation of Venezuelan oil in presence of caustic soda is diluted with gas oil or lighter hydrocarbon, stirred with 4 per cent of 98 per cent sulphuric acid, and allowed to stand; acid resins and sulphate form a bottom layer which is removed.  The upper layer is either worked up to a mineral oil of high naphthenic acid content by filtration through fuller's earth and removal of the diluent, or the naphthene acids are extracted by aqueous lye and acidification of the extract and the gas oil is removed from the recovered oil by distillation.ALSO:Naphthenic acids are recovered by acidifying with concentrated sulphuric acid the residues obtained when mineral oils are distilled with alkali.  The residues may first be diluted with liquid hydrocarbons.  For example, the residue of the distillation of Venezuelan oil in presence of caustic soda is diluted with gas oil, stirred with 4 per cent of 98 per cent sulphuric acid, and allowed to stand to separate acid resins and sulphate.  The naphthenic acids are then extracted from the oily upper layer by aqueous alkali and recovered by acidification of the extract.

IPC: F02P17/02
Filed: 1947-01-21
Abstract: 620,542. Testing ignition. ETABLISSEMENTS JAPY FRERES. Jan. 21, 1947, No. 1944. Convention date, March 29, 1946. [Class 7 (iv)] In an apparatus for checking the ignition system of an internal combustion engine comprising an oscillograph, means are provided, both to cause the trace on the oscillograph screen to describe a closed path during each complete cycle of the engine and to modulate the path in accordance with the voltage developed by the ignition system. The output of a single phase alternator 1, Fig. 1, which latter is driven from a four stroke engine 2 in such a manner that its frequency is equal to half the engine speed, is supplied to one grid 4a of a thermionic valve 4, the anode of which is connected to a resistance capacity unit 5 in order that two voltages in quadrature may be obtained for feeding the X and Y plates of an oscillograph 6. Under these conditions the trace on the oscillograph screen will be circular and its speed half the engine speed. Sparking plugs 7 supplied from a magneto M are connected through low capacity condensers 8 to a second valve grid 4b so that the sparking impulses, in firing sequence, are superimposed upon the trace as shown in Fig. 2. To obtain a datum point in each revolution and to enable the angle of advance or retard of the ignition to be ascertained, a cam operated switch on the alternator shaft connects a battery 10 and condenser 11 to one of the control grids of the valve 4 thereby causing a radial line to be traced on the oscillograph screen. A datum cylinder may be indicated by removing its sparking plug connection to the valve 4. The radius of the circular trace may be proportional to the alternator voltage, and a potentiometer, which is connected in the lead to the valve grid 4a to enable the radius to be adjusted, may be calibrated in terms of engine speed. The oscillograph screen may either be covered with a removable transparent material such for example as the material known under the Registered Trade Mark " Plexiglass " upon which has been marked the impluses resulting from a standard magneto and plugs, or a rotatable plate with a normal trace circle and four other circles, two of greater and two of lesser radius, each pair corresponding to 5 and 10 Kilovolts for example. In a modification, utilisation of a two-phase alternator enables the resistance capacity unit to be dispensed with. In another modification the sparking impulses are fed directly to the Y plates of the oscillograph so enabling the valve to be omitted.

Title: Improvements in and relating to electro-pneumatic compressed air brakes for vehicles
IPC: B60T13/66
Filed: 1959-01-20
Abstract: 841,232. Electro-pneumatic brakes. VERWALTUNGSGESELLSCHAFT DER WERKZEUGMASCHINENFABRIK OERLIKON. Jan. 20, 1959 [Jan. 27, 1958], No. 2070/59. Class 103 (1). An electro-pneumatic compressed-air brakes system, particularly for railway rolling stock, is provided with control valves 17 controlling the charging and discharging of the brake cylinders, each of the control valves 17 being operated by the force of an electromagnet fed from a source of current through an electric amplifier 18, the output current of which is positively related to a control input voltage, the amplifier 18 being provided with a negative current feedback making the current in the electromagnet independent of fluctuations in the resistance of the electromagnet. Referring to Fig. 1, the amplifiers 18 are shown as being operative by a driver's brake valve 10 constituting a variable resistance; the main line auxiliary reservoir and brake cylindei being represented at 5, 21 and 19 respectively, the member 17 being an electropneumatic control valve, shown in detail in section in Fig. 3. The manner in which the negative feedback is supplied to the electromagnet 61 of the amplifier valve 18 is shown in the detail in section in Fig. 3. The manner in which the negative feedback is supplied to the amplifier valve 18 is shown in the circuit of Fig. 2. When a voltage increase occurs owing to an increasing voltage of the battery 36, the current then input, flowing through the diode in the blocking direction, produces a voltage drop on the resistor 41, which reduces the voltage on the diode. In this manner on the diode 64, a voltage results, which is independent of the fluctuations of the voltage on the battery 36 to a far reaching extent.
