Title: An improved binder for binding an aggregate and process of manufacturing same
IPC: C10L5/44
Filed: 1924-09-16
Abstract: 244,517. Carpenter, S. W., and White, G. N. Sept. 16, 1924. Plastic compositions containing humus. - A binding agent for use particularly in the manufacture of fuel briquettes is prepared by subjecting soft vegetable tissue to aerobic fermentation with retention of the non-gaseous fermentation products, and adding alkali to the material either before, during, or after the treatment. Suitable vegetable materials are straw, water weeds, cactus, pricklv pear, rushes, grass, bagasse, beet sugar residues, sisal, hemp, flax residue, soya bean waste, and leaves or stems of bracken banana, maize, and potato. They are prefetrably used fresh cut, but a partly fermented material, such as hay, may be used if it has retained substantially all the non-gaseous fermentation products. The alkali may be partly replaced by an alkaline earth, and it may be added in two stages. The binding agent may be desiccated for transport and subsequently restored to its original form by kneading with water. Several examples of the method of preparing the binding agent are given, of which the following is typical 1 cwt. of dried grass is boiled for 24 hours, the liquid is drained away, and the residue is bruised or brushed, placed in a shallow wooden tray, and watered with 2 gallons of solution containing 2“ lbs. of sodium carbonate. 2 lb. of decayed fruit or grass is added to aid fermentation, and the mixture is allowed to stand in a warm place and is periodically turned over and moistened with the liquor from the boiling operation. The product is ready for use in 24 days. Further fermentation may be prevented by a small addition of copper sulphate or other fungicide. In the manufacture of fuel briquettes the amount of binder is usually 1/6 of the fuel, but as little as 1 per cent may be used if high pressure is employed. The fuel may be mixed either with the wet binding-agent, or with the desiccated binder and water, or with the raw materials before fermentation. Specifications 14389/04 and 226,344. [both in Class 50, Fuel, Manufacture of], are referred to. The Provisional Specification describes the production of binding-agents by the above-described method from decomposed vegetable matter such as peat, lignite, and coal, and from soil rich in humus.

Title: Process for the removal of neutral oils from phenolate solutions containing them
IPC: C07C37/68
Filed: 1959-06-26
Abstract: <PICT:0908938/III/1> In a process of removing neutral oils from aqueous solutions of alkali phenolates by steamstripping, the vapours are washed with a solution of an alkali hydroxide in order to prevent loss of phenols in the vapours, and in the neutral oil and water condensate obtained therefrom.  In an example, a phenolate solution having a neutral oil content of 0,42% is introduced through pipe P into a column comprising two sections 1 and 2 packed with Raschig rings.  Steam is introduced into the sump of the column and/or steam is generated by boiling, by means of a heating device, the phenolate solution which collects in the sump of the column.  An 8% solution of caustic soda is introduced into the top of the column through pipe S, the proportion of caustic soda solution being 6% by volume of the quantity of phenolate solution.  A mixture of oil vapours and steam passes through pipe 3 into condenser 4.  The condensate, which separates int oil and aqueous layers in container 5, contains phenols only to the extent that the losses amount to 1%.  The process may also be applied to solutions in which the equivalent quantity of phenol present is greater than the equivalent quantity of the alkali present.ALSO:<PICT:0908938/IV (b)/1> In a process of removing neutral oils from aqueous solutions of alkali phenolates by steam-stripping, the vapours are washed with a solution of an alkali hydroxide in order to prevent loss of phenols in the vapours, and in the neutral oil and water condensate obtained therefrom.

Patent GB-942675-A (GB)
Title: Improvements relating to automatic voltage regulating systems for vehicle generators
IPC: H02J7/16
Filed: 1960-06-24
Abstract: 942,675. Automatic voltage control systems. R. BOSCH G.m.b.H. June 24, 1960 [June 27, 1959], No. 22122/60. Heading G3R. In an automatic direct voltage regulator for a vehicle lighting system, two power transistors are connected by their emitter-collector paths in series with a field-winding of a generator and a potential divider, comprising two resistors, is connected in parallel with the series arrangement, the junction of the resistors being connected to the base of one of the transistors; the ratio of the values of the resistors corresponds to the ratio of the required emitter-collector voltages of the transistors. As shown, delta-corrected windings 11-13 of an alternator 10 supply a battery 15 through a three-phase rectifier 21, lines 16, 18 and a reverse-current rectifier 18. A field 14 is connected in series with transistors 35, 36 across lines 16,18 and is biased from a transistor 41, connected as a blocking oscillator, so as to maintain the line voltage constant. The voltage at a tapping 61 of a potential divider 62-64 is opposed by the voltage across a Zener diode 43 so that the transistor 41 only becomes conductive when the line voltage exceeds a predetermined value. The increasing collector current passing through a winding 50 of a transformer causes voltages to be induced in windings 45, 46 which are connected so as to cause blocking oscillations to occur. The voltage across a capacitor which is charged through rectifiers 48, 52 from windings 45,46 renders the transistor 35 non-conductive and since the base potential of the transistor 36 is fixed by a potential divider 37, 38 this transistor is also rendered non-conductive. Increase in the effective resistance of transistors 35, 36 causes the current through the field 14 to fall and to reduce the line voltage until the blocking oscillations are stopped when the line voltage falls below the predetermined value. The voltage at the junction of the windings 45,46 is maintained constant by a crystal diode 44 having a non-linear characteristic. In a modification, the junction between transistors 35, 36 is connected to line 16 through a resistor and to the junction of resistors 37, 38 by a diode so as to ensure that the transistor 36 is fully non-conductive when transistor 35 is fully non-conductive. In a further modification, the emitter-collector paths of three transistors are connected in series with the field winding, the base voltages of two of the transistors being'determined by potential dividers. The output current from the alternator 20 is limited by developing across a condenser 32 a direct voltage proportional to load current through a current transformer 24 and rectifiers 30, 31 connected as shown. At a predetermined line current the voltage across the condenser 32 is such that a diode 60 conducts to apply a bias to the transistor 41 through the Zener diode and initiates blocking oscillations.

IPC: B23K9/10
Filed: 1948-08-23
Abstract: 648,939. High-frequency control systems for electric welding. RESISTANCE WELDERS, Ltd. Aug. 23, 1948, No. 22199. Drawings to Specification. [Class 38 (iv)] The high-frequency currents accompanying an arc in a resistance or arc-welding machine are utilized to effect some control of the operation of the machine or of ancilliary equipment. Thus, in an atomic hydrogen welding- machine, the high-frequency current components occurring in the work circuit upon striking an arc may be rectified to energize a relay which causes the opening of a normally closed electromagnetic valve in the pipe through which the hydrogen is supplied to the arc. In another embodiment high-frequency components due to an arc struck between the electrode and work by means of a low-voltage are utilized to apply the higher main welding voltage. In the case of a flash butt welding- machine the disappearance of high-frequency components at the moment of butting may be employed to cut off the welding current. Alternatively, the appearance of high-frequency components at the moment of flashing may control the subsequent movement of the moving electrode block.
