Abstract: 418,816. Heaters for air and fuel. AICHER, A. A., 72, Beaconsfield Road, Blackheath, London. Feb. 1, 1933, No. 3112. [Class 7 (iii).] To enable heavy fuel to be used in a carburetter, the air and the fuel are proheated by drawing the fuel to the carburetter around a number of tubes contained in a casing, the said tubes each containing a concentric tube which extends through the casing and through which passes the exhaust from the engine while air is drawn into the carburetter through the thin annular space between the tubes. The heater comprises a nest of about fifty inner tubes c carried by plates g, each of these tubes being surrounded by a slightly larger tube b, the tubes b being carried by plates d, e. The casing consists of superposed annular members k<1>, h, a, k<2> of which k<1>, k<2> form the inlet and outlet for the exhaust. Air enters through slots s and after passing between the tubes b, c leaves by the outlet m. Fuel enters at p, fills the space between the casing a and tubes b and is drawn to the carburetter through the outlet o. The air is stated to receive heat at a rate roughly proportional to its velocity.

Abstract: 1,138,908. Typewriters etc; selective printing. SIEMENS A.G. 27 Jan., 1967 [28 Jan., 1966], No. 4103/67. Heading B6F. [Also in Division F2] In an intermittent drive, for controlling epicyclic gear trains in turn controlling axial or rotational setting of type carriers, caseshifting and feeding of the type carriage, and line feed in teletypewriters, each of three clutches comprises a key 18 arranged in a radial slot 17 through a driving shaft 3 and movable radially of said shaft between two positions in which respectively it does and does not engage a keyway 19 in a driven eccentric 4 rotatably mounted on the shaft 3. The shaft 3 is so driven by a constant speed shaft 1 through a three-gear eccentric drive 2 that its speed varies from zero to maximum and back to zero per revolution of the shaft 1, the shaft 3 being driven intermittently half a revolution at a time. Three eccentrics 4 are arranged to act, via connecting rods 6, on a sun 7, a cage 14 carrying planets 8, 9 and a cage 15 carrying planets 10, 11. The cages are pivotable about the sun 7 and suns 12, 13. An output gear meshes the sun 13. Each of the eccentrics 4 is stationed in its rest position by spring-loaded rollers 20 engageable in a pair of diametrically disposed notches 21 in the eccentric. The eccentrics 4 can be clutched to the shaft 3 when the latter is stationary. In each clutch, the key 18 comprises a part having two indentations engageable by a spring- loaded retainer ball in the shaft 3, and having a length equal to the diameter of said shaft. A V-shaped spring 24 has arms acting on the two ends of the key, one arm being turned back on itself so that the spring arm free ends point in the direction of rotation of the shaft 3. A cam 22, secured to the shaft 3 by a small part of the key, has two rise portions by which the spring arms are spread and freed after half a revolution of the shaft 3. The two spring arms may be respectively prevented from acting on the corresponding key ends by a half-moon shaped stop means 25 of a setting element 5 solenoidactuable against a spring. When set in one position, one arm may be prevented from acting on the key after leaving the full rise portion of the cam whilst the other arm moves the key when such movement is possible and if the key has not already taken up the desired position due to a previous setting. The setting movement of the element 5 must be effected when both spring arms are spread. In Fig. 1, this is not possible when shaft 3 is in the rest state. To overcome this difficulty, the modification shown in Fig. 3 includes an additional mechanism comprising a ring 26 having an actuating lever 28 and extensions 27 which in the rest position hold the spring arms spread. Shortly before the shaft 3 starts to rotate, the ring 26 is rotated so that the extensions 27 free the spring arms.

Title: N-alkylbenzyl substituted polyethyleneimines
IPC: C08L79/02
Filed: 1967-01-27
Abstract: The invention comprises water-insoluble N-alkyl benzyl substituted polyethylene imines containing at least 1% of nitrogen and the use of these compounds, incorporated with hydrocarbon polymers, in order to render the resulting matrix polymer, containing from 0.1 to 1.5% nitrogen, by weight, dyeable by water-soluble anionic dyes.  The N-alkyl substituted polyethylene imines are conveniently prepared, in a polar solvent, from alkyl benzyl halides, preferably the bromide, chloride or iodide, and a polyethylene-imine with a minimum M. Wht. of 10,000.  Hydrocarbon polymers to which the invention is applicable include polypropylene, polyethylene, poly-1-butene, poly-(4-methyl-1-pentene), graft and block copolymers of two or more 1-alkenes or of non-terminal olefins with 1-alkenes, or mixtures of two or more of these copolymers.  It is necessary to treat the mixture of hydrocarbon polymer and dye receptor polymer, in the physical form of filaments, yarns, fabrics, films, sheets &c., with an acidic reagent to render the matrix dye receptive; various acidic materials mentioned are mineral acids; acid anhydrides; acid gases; organo-carboxylic acids, both saturated and unsaturated, mono- and di-functional; halides which liberate hydrohalic acids with water; non-matallic halides and oxyhalides; metal halides; organic acid halides and organic halides where the halogen is on a carbon atom adjacent to an activating group, e.g. benzyl, allyl and compounds capable of complexing with basic nitrogen polymers.ALSO:Drawn or undrawn fibres, filaments, yarns and fabrics made from hydrocarbon polymers blended with a dye receptor polymer which is an N-alkylbenzyl substituted polyethyleneimine are dyed advantageously using water soluble anionic dyes.  The hydrocarbon polymers must contain 0.5 to 10% of the N-alkyl benzyl polyethylene imine and are made highly dye-receptive by treating with an acidic reagent, the materials then being dyed in the conventional manner.  This method of dyeing is suitable for polypropylene, polyethylene, poly-butene, poly (4-methyl-1-pentene) or mixtures thereof the alkyl benzyl substituted polyethyleneimines must be such that they contain at least 1% by weight of nitrogen and typical examples are where the alkyl variety contain from 6 to 20 carbon atoms.  Suitable acidic reagents for treating the matrix polymer before dyeing include phosphorous pentachloride, sebacoyl chloride, hydrochloric acid, monochloroacetic acid and dichloracetic acid.  Typical dyes include Capracyl Orange R, Alizann Sky Blue B, Reectone Red 2B, Pontamine Fast Yellow 4GL and Alizann Red 5.
