Title: Improvements in or relating to road construction
IPC: C08L95/00
Filed: 1934-05-05
Abstract: A roadway or pavement is prepared by compacting on the surface a mixture of mineral substances of graduated grain sizes to form the minimum cavities, a liquid binding agent and a powdered solid binding agent soluble in the liquid to a slight extent.  With coal or lignite tar powdered petroleum pitch is used and with mineral oil, powdered coal tar pitch is used.  The mixture is applied cold and within a few hours of its preparation.  A small quantity of powdered stone and solid binding agent may be strewn on the surface during rolling.

Abstract: 1,101,901. Ratchet mechanism. DSO METALOOBRABOTVASHTI I DARVOOBRABOTVASHTI I INSTRUMENTI. 28 March, 1966 [26 March, 1965], No. 13669/66. Heading F2Q. [Also in Division B3] An indexing mechanism comprises toothed wheels 3 on a driven shaft 2, cylinders 4 radially mounted in a body 1 around the wheels 3, and operating pins 5 located in the cylinders 4 and having wedge-shaped ends which are adapted to be moved sequentially into and out of engagement with the toothed wheels causing stepped angular rotation thereof. Control mechanism comprises a plurality of nozzles 8, one corresponding to each cylinder 4, cooperating with openings formed in a drum 6 secured to the shaft 2. Fluid under pressure is fed to the nozzles 8 and to valves associated with the cylinders 4, the arrangement being such that when one of the nozzles 8 is in coincidence with an opening in drum 6, a driving impulse is transmitted to the appropriate valve to cause a pin 5 to engage the toothed wheel 3 and rotate the wheel one step. As the drum 6 rotates, it causes the opening to move out of coincidence with the nozzle 8 whereby a further impulse is transmitted to the valve to cause the pin 5 to disengage from the toothed wheel. As shown, two toothed wheels 3 are provided, and a second system of nozzles (not shown) is provided for counting either the strokes of each cylinder or the separate movements of the shaft. The valves in the control system can be formed by pneumatic or hydraulic motors, electromagnets or flexible membranes.

Title: Improvements in and relating to stabilized hydrocarbon distillates and manufacture thereof
IPC: C10M131/12
Filed: 1954-05-11
Abstract: A hydrocarbon distillate boiling at least to a substantial extent above the gasoline boiling range is stabilized against discoloration and sediment formation during storage by adding to the distillate a salt of a carboxylic acid and an N-alkylsubstituted alkylene polyamine, this salt containing at least 20 carbon atoms in its molecule.  Hydrocarbon distillates which may be treated in this manner include burner oils, fuel oils, furnace oils, diesel oils, jet fuels, lubricating oils transformer oils and turbine oils.  They may comprise straight-run petroleum distillates, cycle oils from the catalytic or non-catalytic cracking of petroleum feedstocks, or hydrocarbon distillates derived from the Fischer-Tropsch synthesis or oxo process.  Lists are given of carboxylic acids and alkylene polyamines from which the salts may be prepared; these salts may be neutral, basic or acidic.  In the examples, the salts added to hydrocarbon distillates are (a) the neutral or basic salt derived from the N-alkyl alkylene polyamine known as "Duomeen T" (the word "Duomeen" is a Registered Trade Mark), and the mixture of dicarboxylic acids known as "VR-1 acid", (b) "Duomeen T" dioleate, (c) the "Duomeen T" salt of a tall oil acid and (d) N-lauryl-1, 4-butylene diamine stearate.

Title: Transistor cirucits
IPC: H03K19/088
Filed: 1972-03-24
Abstract: 1330605 Anti-saturation circuit INTERNATIONAL BUSINESS MACHINES CORP 24 March 1972 [23 April 1971] 13810/72 Heading H3T Saturation of a transistor T 1  is avoided by connecting the collector and base of a like conductivity further transistor, such as To to the base and collector of it respectively and arranging the base potential of this further transistor so that it conducts when the transistor T 1  nears saturation. In a TTL circuit (Fig. 1) the bias is obtained via a potential divider R 31 , R 32  across the collector-base of the input transistor. Alternatively, the transistor, T 0  and T 2  can be combined to have common base and collector and separate emitters. (Figs. 4 and 5, not shown). One emitter of the combined transistors may be directly connected to the collector of transistor T 1  or be tapped to its resistive load. This second arrangement improves its drive capabilities. Integrated circuit constructions are described and the circuit may be used in multivibrators and amplifiers.

Abstract: 146,936. Mining & Metallurgical Processes Proprietary, Ltd., (Assignees of Rigg, G.). July 9, 1919, [Convention date]. Rotary furnaces.-In roasting operations in which a current of air is forced or drawn through a charge of ore on a grate, uniform passage of the blast is ensured by periodically perforating the clinker formed on the grate. An apparatus for use in the desulphurization of lead ores comprises a pot or casing 20 mounted on trunnions on a wheeled frame 22 and having within it at a suitable level a grate 27. Beneath the grate is a plate 32 mounted on a vertically-movable stem 30 and carrying teeth 35 arranged in alinement with the grate apertures. By operation of the telescopic lever handle 41 the teeth can be moved through the apertures in the grate to perforate the clinker.

Patent GB-1078555-A (GB)
Title: Process for purifying polymer solutions
IPC: C08F6/02
Filed: 1965-04-05
Abstract: Catalyst residues are removed from a polymer solution by passing the solution and a heavier liquid which is immiscible, or at least not completely miscible with said solution, and in which the catalyst residues are soluble, in co-current relationship through a column with internal obstructions, in which column the heavier liquid forms a continuous phase, subjecting the liquids in the column to flow pulses and separating the polymer solution from the heavier liquid. The heavier liquid is preferably demineralized water free from O2 and at a temperature of 0 DEG  to 250 DEG  C.  An acid, base and/or wetting agent may be added to the water.  The column obstructions are constrictions in the column wall, perforated plates or filling bodies, e.g. saddles or rings. Solutions of saturated polymers, e.g. polybutylene-1 and copolymers of ethylene and propylene, unsaturated polymers, e.g. polybutadiene and polyisoprene, and rubbery polymers of at least two 1-alkenes and at least one hydrocarbon with two double bonds such as terpolymers of ethylene, propylene and hexa-1,4-diene, cyclo-octadiene, dicyclopentadiene or norbornadiene, may be purified in the column.  On leaving the column the polymer solution and heavier liquid are separated by centrifugation or are allowed to stand.  The polymer is recovered from solution by evaporation of the solvent.  In examples the vanadium content of a gasoline solution of an ethylene/propylene/dicyclopentadiene copolymer produced using an AlC2H5Cl2/VOCl3 catalyst is reduced by passing the solution with water through a column at 20 DEG  C.
