Title: Improvements in or relating to motor fuels
IPC: C10L1/16
Filed: 1950-08-16
Abstract: A hydrocarbon base gasoline having an ASTM 50 per cent distillation point below about 310 DEG F, is mixed with about 0.5 volume per cent of a solvent oil and from 1.0 to 2.5 volume per cent of dimethyl carbinol (isopropanol).  The solvent oil consists essentially of a liquid hydrocarbon mixture having a kauri-butanol solvent power above about 20, a 50 per cent distillation point above 350 DEG F at 10 mm. Hg pressure, a viscosity at 100 DEG F not above 450 S.U.S. and an A.P.I. gravity of about 18-20 degrees.  The dimethyl carbinol should be at least 98 per cent pure.  If desired, crude commercial (65 per cent), dimethyl carbinol may be added to gasoline and the aqueous phase which separates removed to leave a gasoline phase containing dimethyl carbinol of about 98 per cent purity.  Preferably, however, the crude dimethyl carbinol is purified in known manner before use. The use of the fuel compositions of the invention prevents icing of the carburetter and consequent engine stalling in cool, humid weather conditions.  Other additions may be present, e.g. lead alkyl anti-detonants, lead scavenging agents, dyes, gum inhibitors, oxidation inhibitors, metal deactivators such as N, N1-disalicyal-1, 2- diamino propane, and N, N1-disalicyal-1, 2-diamino ethane, and rust preventatives such as sorbitan mono-oleate, pentaerythritol mono-oleate, and amine phosphates, nitrates and nitrites.  In comparative examples a solvent oil of kauri-butanol value 25.2, 50 per cent distillation point 413 DEG F at 10 mm Hg pressure, viscosity 75.3 S.U.S. at 100 DEG F and A.I.P. gravity 26.6 degrees is used in the following compositions (1) gasoline and 0.5 per cent by volume of solvent oil (2) gasoline and 1 per cent by volume of 99 per cent dimethyl carbinol (3) gasoline, 0.5 per cent solvent oil and 1 per cent of 99 per cent dimethyl carbinol (4) gasoline containing lead tetraethyl, 0.5 per cent solvent oil and 0.1 and 2 per cent of dimethyl carbinol, and (5) as in 4 with 2.5 per cent of 99 per cent dimethyl carbinol.

Title: Air-blast circuit breaker with multiple interruption
IPC: H01H33/16
Filed: 1960-06-13
Abstract: 928,916. Gas-blast switches. A. G. BROWN, BOVERI & CIE. June 13, 1960 [June 13, 1959], No. 20703/60. Class 38 (5). Each phase of an air-blast circuit-breaker comprises a plurality of elements each of which has two power interrupting units and a voltage disconnecting unit subjected to air blast, one of the power interrupting units being in parallel with a low-ohmic resistor. In Fig. 1 an auxiliary compressed-air container 1 supplied through an insulator 15 carries power interrupting units 2, 3 connected in parallel with high and low ohmic resistors 4, 6 and controlled by valves operated by pistons 7, 8 housed in a casing 9 normally exhausted of air, the voltage disconnecting unit 5 being secured to the insulator containing the unit 3. The breaker is opened by admitting air from container 1 to the casing 9 to depress pistons 7, 8, unit 3 opening before unit 2 and both reclosing after air from an insulator 14 has opened unit 5. The units have exhaust valves 13, 13a and pistons 7, 8 have pressure-equalizing holes and restoring springs 16. The breaker elements may be arranged in a row or symmetrically with respect to a plane. In a modification, Fig. 2 (not shown), one end of the low-ohmic resistor is secured to the auxiliary air container and the other end carries the second power unit and high-ohmic resistor, the container also carrying the voltage disconnecting unit whose air supply is used to operate the two pistons and produce the same opening sequence as before. In Fig. 3, main valves 17 controlling the operation of units 2, 3 are arranged in intermediate casings 19 connected, when units 2, 3 are open, to the auxiliary container 1, the high-ohmic resistor being omitted. To open, air is admitted through insulator 14 to depress pistons 22, open valves 17 and exhaust casings 19, thus allowing air from container 1 to open units 2, 3 and flow to exhaust until valves 17 reclose and casings 19 refill with air. This construction may be modified, Fig. 4 (not shown), so that the contacts of the power units are contained in a single intermediate casing enclosing a further casing receiving the moving contacts and a common reclosing spring and being connected to a main valve and piston mounted on the intermediate casing. The latter is connected to the auxiliary air container through a hollow fixed contact forming part of the lower unit and supported by a bushing which is mounted on the auxiliary container and carries the intermediate container.

Title: Improvements in or relating to electro-magnetically operated current interrupters
IPC: H01H50/76
Filed: 1949-08-09
Abstract: 658,073. Electromagnetic interrupters. WIDAKOWICH, M. Aug. 9, 1949, No. 20754. [Class 38(v)] In an electromagnetic vibratory interrupter the reed 5 carries or operates in addition to its ordinary contacts a contact 7, which is in series with the electromagnet and disengages a contact 8 during each oscillation when the amplitude exceeds a predetermined value. In the form shown the contacts 7, 8 are also in series with the self interrupting contacts 3, 4. Springs 11, 12 press the contacts 3, 8 inwards and stops 9, 10 limit inward movement. When the amplitude is sufficient for the stop 10 to be engaged, the contacts 7, 8 open so cutting off the current to the magnet 2. The device thus operates at substantially the same amplitude and frequency even though the applied voltage varies. A variable resistance 15 may be arranged across the contacts 7, 8 to adjust the effect and a condenser 13 and resistance 14 absorb the sparks at both pairs of contacts. In a modification the armature 1 instead of carrying the contact 7 carries a rod which strikes the spring carrying the contact 7. In a practical form of the invention, Figs. 3-5 (not shown), a single magnet and armature control five sets of contacts and are mounted with the contacts on a frame supported by springs inside another frame.

Abstract: Heat-insulating compositions are made by mixing porous plastic particles with an inorganic binder consisting of a suspension of water-containing particles of alkali metal silicate and inorganic fillers in an aqueous solution of an alkali metal silicate, and solidifying at a temperature above >0 DEG  C. but below that at which the plastic sinters.  Solidification can be assisted by extracting water down to a content of 20%, by treatment with carbon dioxide, or by the application of pressure. The porous plastic may be polyurethane, polystyrene, copolymers of styrene and acrylonitrile, acrylic acid, or butadiene, vinyl chloride, or copolymers of vinyl chloride and vinylidene chloride.  Flame retardants such as inorganic halogen compounds or mixtures of chloroparaffins and antimony trioxide may be included. The alkali metal silicate powder is preferably sodium silicate containing 16-20% water and having an Na2O/SiO2 ratio of 1:2.0 to 1:4.0.  The solution is of 15-60 DEG  Be1 concentration, and the total water content varies between 25 and 75% of the weight of the silicate. Magnesia, talc, calcium carbonate, powdered asbestos, glass, quartz, zinc carbonate, sodium silicofluoride, or silica gel can be used as fillers in the ratio of 1:1 to 4:1 relative to the anhydrous silicate.
