Title: Method of and means for increasing the calorific efficiency by supplying a mixture of producer gas rich in hydrogen and heavy oils to an internal combustion engine
IPC: F02M21/00
Filed: 1933-10-04
Abstract: 426,491. Actuating-materials. GRANICHSTAEDTEN, P., 18, Marokkanergasse, Vienna. Oct. 4, 1933, No. 27363. Convention date, Oct. 5, 1932. [Class 7 (ii)] [See also Group XII] Pre-ignition is prevented in engines using producer gas, containing more than 15 per cent of hydrogen, by adding thereto heavy oil in a vaporized state, the temperature of the gas during its passage from the producer to the engine being such that condensation of the heavy oil vapour is prevented. The oil is vaporized, either in a vaporizer 7 arranged at the top of the producer 1, or at a point in the pipe-line where it is heated by the hot producer gases, or in a vaporizer 8 heated by the exhaust pipe 6 of the engine, the supply being controlled by drip cocks 14, 15 ; alternatively the heavy oil may be injected by a pump into the gas pipe-line which is maintained at a high enough temperature to vaporize the oil. Steam generators 9, 10 supply a larger amount of steam than usual to the producer 1, the resulting gas, rich in hydrogen, passing through a dust chamber 2 with baffles 3 and a dry purifier 4 ; part of the steam is superheated in a jacket round the dust chamber 2. The whole of the apparatus leading to the engine cylinder 5 is kept at such a temperature that condensation of the oil vapour is only just avoided. The following oils may be used, viz.-crude petroleum, gas and heating oils, tar oils produced from coal, lignite, or peat, asphalt, pitch, oils containing anthracene and medium and heavy hydrocarbon oils. Examples of solid fuels which may be used in the producer are anthracite coke, wood, peat or corn cobs. Alternatively catalysts-e.g. iron or copper oxide or sodium carbonate-may be used.

Abstract: 690,336. Hydraulic shock absorbers. ELECTROL, Inc. Oct. 25, 1949 [Nov. 27, 1948], No. 27400/49. Class 108 (iii). [Also in Group XXIX] In a device for varying the pressure in a closed hydraulic system a piston member has a large piston portion and a smaller piston portion working in corresponding cylinders, the smaller cylinder being in communication with the closed hydraulic system, valve mechanism is provided for connecting the larger cylinder alternatively to a source of pressure fluid or discharge, and this valve mechanism is mounted in and movable with the piston member. The intensifier shown in Fig. 2 comprises a piston 32 working in a cylinder 18 and integral with a smaller diameter piston 30 working in a cylinder 20. A valve 64 which is carried in the interior of the piston controls the connection of the left-hand side of the piston 32 either to a source of fluid under pressure connected to an inlet 40 or to a sump connected to an outlet 73. The valve is operable manually or mechanically by means of a rod 75 and is returned to a neutral position by a spring 87. By supplying fluid under pressure to the left side of the piston 32 the piston 35 is advanced in its cylinder to apply pressure to liquid in a pipe 15 or by releasing fluid from the left side of the piston the pressure in the pipe 15 is relieved. Hydraulic pressure can be used to operate the larger piston. Passages 83, 84, 85, 86 are provided in the valve to balance the pressures on its opposite ends. It is stated that a seal may be inserted at the bottom of a recess 77. The pipe 15 leads to an hydraulic cylinder and an hydraulic accumulator of the type in which a flexible diaphragm separates liquid below the diaphragm from air above the diaphragm. The invention can be applied to hydraulic shock absorbers for motor vehicles.

Title: Improvements in electrodeposition of nickel
IPC: C25D3/16
Filed: 1959-08-14
Abstract: Addition products are formed from watersoluble acetylenic compounds, especially a substituted or a ,a 1-disubstituted acetylenic compounds, by reaction with an alkali metal sulphite or bisulphite. The products are believed to contain sulphonic groups.  The reactants may be dissolved in water and heated under reflux; addition of oxygen or benzoyl peroxide accelerates the reaction.  Addition of a "free radical inhibitor" such as hydroquinone slows the reaction.  Examples are given of the formation of such compounds from 2-butyne-1,4-diol, 1,4-dichloro-2-butyne, 1,4-di-(b -hydroxyethyl)-2-butyne, and 1-4-diacetoxy-2-butyne with sodium bisulphite; many other suitable acetylenic compounds are listed, including alcohols, ethers, carboxylic esters, amines, hydroxyamines and halogen compounds.

Title: Method of selecting and establishing connecting paths between coupling groups in telecommunication, preferably telephone systems
IPC: H04Q3/00
Filed: 1961-08-04
Abstract: 939,538. Automatic exchange systems. STANDARD TELEPHONES & CABLES Ltd. Aug. 4, 1961 [Aug. 5, 1960], No. 28474/61. Class 40 (4). In a system in which connections are set up over two or more coupling blocks A, B, each of which are divided into sections A1 ... An, B1  ... Bm, a forward marking network is provided with switching means such as LKA1, whereby markings are only extended between sections involved in setting up the call. By this means simultaneous settings up of different calls may be effected provided no particular section is involved in more than one of the calls. The drawing shows only the control network, the speech paths following the same course with the exception that the speech outlets from group A are directly connected to inlets of group B. In setting up a call from inlet E 1  of group A to outlet b12 of group B, the inlet is marked and the masking fans out through all free paths in section A1. At the same time the identity of the outlet b12 (or possibly a group of outlets from B1) is fed to a marker MA1 which sets a switch RVA1 to connect up an auxiliary marker MB1 associated with section B1. Marker MB1 is fed with the identity of the outlet b12 within its section and sets a switch LZB1 to apply a backward marking to outlet b12. At the same time a switch LKA1 is operated over RVA1 and this connects up the forward making leads of section A1 to the corresponding leads of section B1 to permit continuation of the forward marking fan-out in section B1. Selection is then effected amongst the free paths backwards from the outlet b12 to determine a free route and the connection set up and held independently in accordance therewith in by known methods, the control network being then used to set up further calls. In the event of an attempt to set up two calls using the same section, the calls are set up successively either in random order in with a predetermined order of priorities. The invention may be extended to several groups in tandem. Each section may comprise a plurality of cross-bar switching stages. Switches LKA1 may be of the relay type or electronic e.g. diode switches or transistors. Specification 794,815 is referred to.

Title: Method of recovering potassium salts as potassium carbonate from the waste liquor of fermentation industries
IPC: C12F3/00
Filed: 1948-11-03
Abstract: Potassium salts are recovered as potassium carbonate from waste fermentation liquors by concentrating the liquors, e.g. to a solids content of 50 to 60 per cent, burning the concentrate with a limited amount of air and converting the potassium sulphide thus formed to the carbonate by carbonation.  The combustion may be effected continuously by causing the concentrated liquor to fall through the hot combustion gases into the combustion zone of the furnace used; the molten residue from the furnace may then be dissolved in water and reacted with carbon dioxide to form potassium carbonate, which may be recovered in solid form, and hydrogen sulphide which may be recovered per se.  The combustion gases may be used, e.g. for producing steam in a boiler for concentrating the liquor.  Potassium sulphate may be added to the waste liquor before or after concentration.

Title: Improved process for the opening up of cellulosic vegetable materials, more particularly straw
IPC: D21C1/00
Filed: 1935-10-18
Abstract: In a process for the manufacture of artificial spun fibres, the cellulose is obtained from straw or the like, particularly annual plants and grasses, e.g. alfa grass, broom, hemp and flax stalks, corncobs or cereal straw, is converted into a solution for spinning and is spun, e.g. by the viscose process.  The raw material is subjected to a pre-boiling at about 4--10 atmospheres pressure with a boiling lye derived from a final boiling.  In the case of alkali, these lyes are still weakly alkaline but also contain organic substances.  Advantageously, the pre-boiling is followed by a steaming under pressure, the final boiling then being carried out with fresh alkali, if necessary with the addition of reducing substances.  In an example, straw is boiled with waste lye for 1--2 hours at a pressure of 4--10 atmospheres.  The liquor is then removed and the half-opened fibres are steamed for 1--2 hours at the same pressure.  After removing any condensate, the fibres are boiled with dilute sodium hydroxide for 4 hours at 4--10 atmospheres.  The lye is then run off and employed for the first boiling of a fresh batch of material.  The process of the invention results in an economy of bleaching materials, e.g. chlorine.
