Abstract: 1,229,237. Coating. LICENCIA TALALMANYOKAT ERTEKESITO VALLALAT. 10 Dec., 1968 [16 Dec., 1967], No. 58724/68. Heading B2E. A pliable laminar material comprises a carrier, a layer composed of fibres consisting of the material of the carrier itself or of fibres applied on the surface of the carrier. Such that it contains a proportion of thermoplastic fibres, and a film formed by melting the outer surface of the fibre layer. The material is produced by forming a fibre layer, which contains a proportion of thermoplastic fibres, on the surface of the carrier and optionally applying a thermoplastic synthetic material on the fibre layer in the form of a solution, dispersion or powder, then melting the outer surface of the fibre layer and, if present, the synthetic material by heating thereby forming an outer film, compacting the system so obtained by compression and, if desired providing the outer film with a pattern. The fibre layer may be formed by napping the material of the carrier or by applying a binder to the surface of the carrien and electrostatically applying cut fibres of the desired composition onto this or by forming loops from the material of the carrier and cutting the loops open.

Abstract: 1,231,759. Strontium ferrite. WESTING- HOUSE ELECTRIC CORP. 21 Feb., 1969 [19 March, 1968], No. 9498/69. Heading C1A. [Also in Division H1] Magnetic strontium ferrite is made by mixing, reducing the particle size of, and reacting a charge comprising celestite, a source of carbonate ions, e.g. soda ash, a predominantly ferric oxide containing-substance, e.g. haematite, and water; removing the major proportion of water-soluble sulphates produced, and then calcining the mixture, e.g. at 900-1400 C. to form strontium ferrite of predominantly magnetoplumbite structure. The ratio of soda ash to celestite is preferably 0À5-1:1. Particle size reduction may be effected by ball-milling for 2-24 hours, at not more than 70 C. to produce a particle size of 5-10 Á. Lead monoxide (up to 2% by wt. of solids) may be added to the charge to be milled. The ferrite clinker may be formed into permanent magnetic bodies by milling, pressing and sintering, or by incorporating it in polymeric binders which are hardened after orientation of the ferrite particles.

Abstract: 1,264,703. Heat treating apparatus. P. H. LYTZEN. 19 May, 1969 [4 March, 1969], No. 25440/69. Heading B5B. [Also in Division F4] Films or continuous filaments of plastics material are heat treated by passage through a kiln in which drying air circulates, transverse compressed layers being produced in the drying air directly before it meets the material to be heat treated. Simultaneously with the heat treatment, the plastics films or filaments may be stretched to 10-30 times their initial length at about 120‹ C. Rapid pulsations of air produced by a centrifugal fan 6 are directed against a web 1 to be dried, thus displacing the film of cold air tending to adhere to the web. Baffles 27 ensure that air repeatedly impinges on the web before being recirculated past a heater 8. To prevent overheating of the web, dampers 9 and 11 open and damper 10 shuts when the web is stopped so that cool air is drawn in by the fan 6. A temperature sensor 20 controls the heater 8 during normal operation to maintain the correct temperature of drying air, and-during shutdown, a sensor 21 controls damper 10 to bleed a small quantity of hot air to keep the temperature of the air flow at about 100‹ C. Build up of heat in heater 8 during shutdown ensures a quick resumption of the correct working temperature on start-up. Similar return paths 14 and fans 6 may be located on each side of the web, Figs. 4-6 (not shown) and a plurality of fans may be provided longitudinally of the web. Instead of a web, articles on a roller or band conveyer may be dried in the apparatus.

Abstract: 1288508 Hydrostatic transmissions ROBERT BOSCH GmbH 15 Jan 1970 [16 Jan 1969] 1939/70 Heading B7H A motor vehicle, especially a tractor, having an hydrostatic wheel drive on the front axle and a mechanically driven rear axle has a threeposition valve 16 which provides a connection between the hydrostatic circuit and atmosphere when the vehicle is travelling at high speed, e.g., on the road. The hydrostatic transmission is put into operation only when it is necessary to apply more tractive effort. An internal combustion engine 2 drives the rear axle 4 and an adjustable hydraulic pump 5 which supplies hydraulic motors 7, 8 driving front wheels 7, 8 through reduction gears 9, 10. When the valve 16 is in the position II, as shown, a line 23 communicating with the atmosphere in a reservoir is connected to a line 15 while a line 24 is connected to a line 25 and a line 27 is connected to a line 27<SP>1</SP> having a throttle 28. Line 27<SP>1</SP> is connected to a line 18 between a pump 19 and pump 6 and supplies a cooling circuit 26 for pressure medium. In the position I of the valve 16, pump 6 supplies motors 7, 8 through lines 17 and 15, and pressure medium returns to reservoir 21 by lines 25 and 24. In the position III, reverse direction of the motors 7, 8 is produced for reverse travel of the vehicle. Alternatively, the rear wheels may be driven by an hydrostatic transmission, the front axle may be the main drive axle, or the hydrostatic transmission may be used in vehicles having more than two axles.

In one form, light from the tube 10 passes through a lens 23 and the means 24 to be focused on the plane 22, and thence through a lens 27 to be focused on a rotatable and axially movable drum 26 carrying sensitized paper. In another form, Fig. 11, the character plate is divided into a number of sections arranged in columns and rows, each section having columns and rows of characters. One section is made luminescent by the electron beam, and the complete section is projected on to the photoconducing plate 29 of an image pick-up tube 28, which comprises a focusing field generating coil 28a, a position selecting deflector coil 28b, and a character scanning deflector coil 28c. The coil 28b selects a point in the area or sub-section of the section containing a selected character, and the coil 28c causes an electron beam to scan the character from the selected point. The character can thus be read out, and is converted into electric signals which pass through an amplifier 33 and to a display tube 32 similar to the tube 10 or having a head including fibre optics element, and thence to the lens 27. The lens 27 may be one of a plurality of lenses in a turret or a zoom lens for movable magnification, or the size of the character can be varied by a focusing coil 32c and a simple lens 27 can be used. A further lens of semi-circular arcuate crosssection may be provided between the lens 27 and the paper and according to the orientation of the further lens the image of the character can be modified, e.g. by vertical or horizontal elongation or inclination.

Abstract: 1307922 Testing yarns HEBERLEIN & CO AG 5 May 1971 [6 May 1970] 21769/70 Heading D1F A comparative assessment of "crimping force" i.e. the contractile force arising in a textured yarn (which has been extended to remove temporarily the texturing deformations e.g. crimp) due to the tendency of the deformations to return when the yarn is restrained from freely contracting in length under the influence of that force, is obtained by feeding a pretensioned textured yarn through a zone between two forwarding devices wherein the yarn is heated and partially relaxed and the crimping force therein operates an indicator. In the operation of the apparatus shown, a crimping force arises in the yarn forming a loop between feed rollers 16 and 22, passing through tubular heater 18 and around a pulley 20, in dependence upon the pretensioning by a tensioner 12 and the overfeed e.g. 6% of rollers 16: consequent movement of the pulley 20, and hence of a loaded, counter-weighted, pivotally mounted arm 24, is measurable on a calibrated scale 32. The hanging, loading chain 28 is secured at one end to an adjustable roller 30 which is employed to determine a coarse setting, for any particular yarn under test, to enable the pivoted arm to operate within the limits of the scale 32 which then provides a fine reading. In another embodiment of apparatus, Fig. 2 (not shown) within a yarn heating and relaxing zone, a single run of yarn passes through a heater (40) thence around a weighted pulley (42) suspended thereby, the approach and departure paths of the yarn to and from the pulley making an angle to the vertical. The pulley is attached to the end of a counterweighted, pivoted arm (46) movable against a calibrated scale (47).
