Title: New or improved appliance for the application of stripes of paint or the like, particularly on road surfaces, sports grounds, or the like
IPC: E01C23/22
Filed: 1956-01-27
Abstract: A mobile appliance for the application of stripes of paint on road surfaces comprises a flat container mounted on a wheeled chassis and in which is fixed a row of spraying nozzles with their orifices directed against the roadway, the nozzles being under a common control.  A mobile container 1 for a paint chamber 10 comprises two plates 6, 7 secured by angle-plate 8.  A presser bar 17 is spaced above the container and by operating a cable is raised by two fingers 18 mounted on the ends of a shaft rotating in bearings on the angle-plate to adjust a row of needle valves 13 which control a row of spraying nozzles 2 at the bottom of the container.  The needle valves are urged to closed position by springs 14, each acting between an abutment 15 on the valve and the plate 7.  The presser bar is depressed by two springs 48, each acting between the presserbar and the top of a bolt 47 securing the bar to <PICT:0792746/III/1> <PICT:0792746/III/2> the plate 7.  A nozzle is put out of action by adjusting a screw 21a on the valve.  Compressed air is supplied to the nozzles through openings 27 and to outlets 32.  Air is supplied through an inlet 46 attached to the plate 6 to produce an air spray from the nozzle 3 to clean the surface in front of the nozzles.  The container is attached to a vehicle by a linkage which comprises two levers 34, 35 pivoted to each side of the angle-plate 8 and to straps 36 which are pivotally secured to a clamp on a shaft of the vehicle. The upper pivots of the levers 35 are adjustable to vary the height of the nozzle.

Title: Improvements relating to the winding of armature cores
Inventor: FARMER CECIL
IPC: H02K15/09
Filed: 1959-01-27
Abstract: 872,079. Coil-making apparatus. GOLDMAN, A. D., and GOLDMAN, Y. Jan. 27, 1959, No. 2912/59. Class 35. An apparatus for winding an armature core of an electric generator or motor uses a precut wire unit sufficiently long to wind the whole core. The core A is mounted with its shaft 45 held in a chuck 44 on top of a rigid post 28. Mounted in sliding relation with the post are two sleeves 27, 29 joined by a rack bar 30 which co-operates with a gear pinion 32 turned by handles 33 and braked by brake band 35. Upper sleeve 27 carries rods 26 attached at their upper ends to an annular member 25 which rotatably supports a table assembly 21, which in turn carries near its periphery a plurality of rotatable spools 22 whose angular spacing is equal to that of the armature grooves. The table has an annular central guide member 40 (Fig. 2). provided with slots 41 corresponding to the armature grooves. On the upper end of armature shaft 45 is loosely mounted an annulus 47 carrying a number of pins 48 equal to the number of armature grooves. The pre-cut wire unit (Fig. 4) comprises sufficient wire 10 to wind the whole armature and may be a single wire or several wires side by side (not shown). The wire is folded back on itself several times to form a number of equal portions 11, equal to the number of armature grooves. Each pair of wire portions 11 is then pressed together (Fig. 5, not shown), wound into a separate coil 16 for most of its length and then one coil is placed on each spool 22, with each bight portion 13 anchored on a pin 48, and a pair of wires 11 arranged in each slot 41 (Fig. 2). A retaining annulus 48<SP>1</SP> prevents the wires moving out of the slots. To wind the armature, table 21 is first lowered to a position below the core (Fig. 8, not shown), so that a pair of wire portions 11 is inserted into each groove. The table is then indexed through 180 degrees and raised so that each pair is inserted into a groove diametrically opposite to its initial one. On now indexing the table through 180 degrees in the opposite direction the wire portions are aligned with their original grooves and the procedure of lowering, indexing, raising and re-indexing is repeated until winding is complete. The complete winding is tested for faults before the bights 12, 13 are cut.

Title: Process of intercalating olefines into halogen-methanes
IPC: C07C17/275
Filed: 1955-02-01
Abstract: Telomerization of olefines with halomethanes is effected with the aid of a reaction promoter which is a metal of the 8th group of the Periodic system or a compound thereof capable of liberating the metal during the reaction (e.g. iron, nickel, cobalt or osmium, or a carbonyl thereof).  The reaction may be carried out at 20-250 DEG  C. (preferably 50-200 DEG  C.) under low or superatmospheric pressure, and in the presence or absence of water or organic solvent.  It may be made continuous by using a large excess of one reaction component (which may be recycled), and gradually adding the other reaction component in small amounts. In examples, undistillable residues are obtained from the products of the reaction of ethylene with carbon tetrachloride and with chloroform, and of n-hexylene with carbon tetrachloride.  Other reaction components specified are propylene and methylene chloride.ALSO:Intercalation of olefines into halomethanes by telomerization is effected with the aid of a reaction promoter which is a metal of the 8th group of the Periodic System or a compound thereof capable of liberating the metal during the reaction (e.g. iron, nickel, cobalt or osmium, or a carbonyl thereof).

It may be made continuous by using a large excess of one reaction component (which may be recycled), and gradually adding the other reaction component in small amounts.  In examples: (1) ethylene is forced into a silver-lined autoclave containing a heated mixture of carbon tetrachloride, iron shavings and water, producing tetrachloropropane, tetrachloropentane, tetrachloroheptane and an undistillable residue; (2) the water in (1) is omitted and an enamelled autoclave used; (3) the iron in (2) is replaced by iron pentacarbonyl; (4) ethylene is introduced into a silver-lined autoclave containing a heated mixture of chloroform and iron pentacarbonyl, yielding trichloropropane, trichloropentane, trichloroheptane and trichlorononane; (5) n-hexylene is reacted as in (1) to give a distillate, which is mainly tetrachloroheptane, and a telomeric residue.

An electric motor for driving the shaft is located between the bearings and separated therefrom by sealing partitions. Water not only serves as pressure fluid for the bearings but also circulates between the housing and an inner cylindrical liner to cool the motor.

Abstract: 860,343. Adhesive tapes; laminates. JOHNSON & JOHNSON. Jan. 29, 1958 [Jan. 31, 1957], No. 3480/57. Class 140. An adhesive sheet or tape comprises a fabric backing of woven or otherwise interlaced threads of fibres or filaments treated so as to be water-repellent, the water-repellent substance being present in amount between 0.5 to 15 % by weight of the fabric, and bearing on one side a waterproof film of thermoplastic material and on the other side a layer of adhesive. The fibres or filaments may be rendered waterrepellent by impregnating the backing substantially throughout with a solution or dispersion of the water-repellent substance and then evaporating the solvent or dispersing fluid, or by applying the substance to the backing in solid form and heating to soften or melt the substance and causing impregnation of the fibres or filaments, e.g. by passage through heated rollers. The water-resistant film may be of polythene and may be between 0.001 and 0.006 inches thick, metals, polymers and copolymers of vinyl chloride or acetate, vinylidene, chloride, acrylonitrile, polyethylene terephthalate, chlorinated rubber, and copolymers of organic esters and isocyanates. The backing may be treated so as to reduce the moisture content thereof to 3% by weight or less prior to the application, e.g. by extrusion coating or lamination, of the film-forming material thereon. The backing may be of woven or non- woven, e.g. carded or garnetted, fabric of natural or synthetic fibres, e.g. cotton, wool, jute, flax, fibre glass, rayon, nylon, or " Terylene " (Registered Trade Mark). Specified water-repellent materials are organo-silicone compounds, metallic soaps, e.g. aluminium stearate, organic titanium compounds, proteinaluminium compound complex, emulsions of waxes and aluminium acetate, e.g. " Phobotex," " Mystolene," " Cerol " (Registered Trade Marks), and " Irgapel ". The adhesive may be pressure-sensitive, e.g. natural rubber, modified rubber, synthetic rubber or rubber-like substance such as polyvinyl butyl ether and polyisobutylene, heat or solvent activatable, e.g. casein glue.
