Title: Process for hydrating hardening and stabilizing calcium cyanamide granules
IPC: C05C7/02
Filed: 1951-01-15
Abstract: Calcium cyanamide granules are hydrated, hardened, and stabilized by maintaining the moistened granules, after the addition of finely divided water, at such a temperature, e.g. under 100 DEG C, say 80-90 DEG C, by the cooling effect of evaporation brought about by a regulated air stream that the chemically combined water amounts to at least 10-13 per cent, and subsequently removing the residual free water by drying.  The water treatment may be carried out in a rotary drum and the air scavenging in a bunker having a funnel shaped bottom so that the air is led through the whole cross section, e.g. by use of porous air-permeable material, or both treatments mal be in one or more rotary drums.  Solutions of fertilizing salts may be used in place of water.ALSO:In the hydration, hardening, and stabilizing of calcium cyanamide granules (see Group III) the granules may be treated with finely divided solutions of fertilizing salts.

Title: Engine cooling fans
IPC: F04D29/38
Filed: 1973-01-08
Abstract: 1379701 Axial-flow fans AISIN SEIKI KK 8 Jan 1973 [8 Jan 1972] 1033/73 Heading F1C A vehicle engine cooling fan comprises blades 11 extending from a hub 10, the angle α, between the chord line 17 of each blade and the plane of rotation being less than or equal to the angle #, between the chord line 17 and the chord line of a leading edge portion 18 of the blade. The leading edge portion 18 is therefore inclined at a negative or zero angle with respect to the plane of rotation. The hydrodynamic forces exerted on the blade when it drips into flood water are therefore reversed or at least nullified over the leading edge portion 18 whereby deflection of the leading edge portion into contact with the radiator is avoided. To assist in confining deflection of the blade to the trailing edge portion 19, a groove 20 or a shoulder (21), Fig. 7 (not shown) may be provided, preferably on the pressure side of the blade. The length  of the chord line of the leading edge portion 18 may be 8% to 30%, preferably 8% to 20%, of the length of the chord line 17.

Title: A rubber composite paving or surfacing mixture for sports grounds, polo grounds, tennis courts, football grounds, race tracks, roads, halls of houses, paths, floors and the like
IPC: C08L97/02
Filed: 1934-09-29
Abstract: A self-vulcanizing composition for use on roads, walls, and floors of houses and sports grounds comprises coir dust, peat dust, wood flour, or sawdust, and rubber latex in the proportions of from one to five of dry rubber to one of coir dust, together with the following vulcanizing agents: 3 to 15 per cent of colloidal or precipitated sulphur, 1/2 to 1 per cent of an accelerator such as diphenylguanidine, quinoidine or piperidine, 2 to 3 per cent of an activator such as zinc oxide and if necessary 1/2 to 1 per cent of an anti-coagulant such as ammonia or caustic alkali, all percentages being calculated on the solid content of the latex.  The composition is left to stand, e.g. for 24 hours in the tropics and longer elsewhere to effect partial vulcanization and then applied to the surface to be covered. Instead of rubber latex a reversible latex concentrate produced by centrifuging, filtering or evaporation may be employed.  The composition may be applied by itself, or on strips or layers or woven sheets of coconut or coir matting, or in the form of portable sections.  To each side of such a layer may be fastened a sheet of expanded metal and these compound sheets fastened to the surface to be covered by screws or pegs.  After partial vulcanization in situ the surface may be rolled and corrugated. The surface may be top surfaced with a bitumen or rubber-bitumen emulsion and covered with a screen of sand or gravel or granite chips.  A portable section may comprise a sheet of rigid expanded metal faced on each side with a layer of coconut or coir matting and embedded in the composition. This section, when partially vulcanized, is pressed to remove surplus water and may be top surfaced with one or more coats of rubber or rubber-bitumen emulsion followed by a screen of sand or gravel or granite chips, or with a self-vulcanizing layer of rubber with or without fillers.  The undersides of the sections are preferably coated with a bitumen or rubber-bitumen emulsion or water proof paint. The sections are fastened down by screws or pegs and the interstices between them are filled with a bitumen or rubber-bitumen emulsion.
Patent GB-1081111-A (GB)
Title: Method of applying coatings
Inventor: LINDEMANN OTTO HANS
IPC: B05D1/18
Filed: 1965-01-11
Abstract: A method of forming a coating on an article comprises first coating the article in a coating compartment with a liquid composition comprising film forming ingredients and a volatile solvent therefor, transferring the article from the coating compartment to a spinning compartment, in which is maintained an atmosphere laden with vapour of the solvent sufficiently to keep liquid, the composition on the article and spinning the article at a peripheral speed sufficient to remove excess liquid therefrom. Escape of solvent vapour from the spinning compartment may be prevented by cooling the vapour so that it condences into the spinning compartment and the temperature of the spinning compartment is preferably such that substantially all the re-condensed solvent revaporizes.  The coating may be done by dip-coating and the article may be rotated during coating and is preferably pre-heated to approximately the boiling point of the volatile solvent.  This heating may be done by vapour of the volatile solvent.  The volatile solvent may be a halogenated hydrocarbon, preferably, trichloethylene but other examples are given.  The excess composition removed may be recycled to the coating compartment for re-use.

Title: Fluid-blast electric circuit interrupters
IPC: H01H33/91
Filed: 1961-01-12
Abstract: 912,251. Fluid-blast switches. WESTINGHOUSE ELECTRIC CORPORATION. Jan. 12, 1961 [Feb. 26, 1960], No. 1334/61. Class 38 (5). Each of the three poles of a fluidblast circuit interrupter comprises a fixed contact carried by the operating cylinder of a puffer mechanism, whose piston is connected to the movable contact operating means by two rods extending through the cylinder and fixed contact structure, the piston during an opening operation, commencing its movement before the movable contact. Figs. 3A and 3B show a weatherproof porcelain tube housing a cylinder 48 carrying a contact plate 62 and fixed contact 32, the latter being enclosed in an orifice 43 communicating with the cylinder 48 through holes in the plate 62, Fig. 4 (not shown). The movable contact 33 bears, through springs 34, 35, against a sleeve 37 connected to a verticallymovable operating rod 22 and carrying another sleeve 39 having a projection 39a engageable with a flange 40 on the contact 33, which is guided by a sleeve 54 and is connected through contact fingers 50 to a terminal plate 53 having a contact 5. The sleeve 39 has portions 45 connected to piston-rods 46 secured to a piston 47, the pressure on whose upper face is stabilized, during contact opening and closing, by apertures 49 in the cylinder 48. To open, rod 22 is moved downwards, thus lowering the piston 47 to build up pressure in the cylinder 48 until members 39a, 40 engage, whereupon contacts 32, 33 separate and the arc between them is extinguished by a fluid blast from the cylinder 48. The springs 34, 35 faciliate reclosure and provide the contact pressure. Porcelain housings 24, 25 are mounted on a housing 11 containing the operating mechanism for the rod 22, and all three poles of the interrupter are carried on a movable truck 2 which supports a mechanism compartment 13 operating all the pole mechanisms simultaneously, closing being by solenoid action, thus tensioning opening springs which are retained latched until tripping. The interrupter may be used with metal-clad switchgear, its external contacts 4, 5 co-operating with contacts 7 on a panel 10. Alternative orifice structures are described, Figs. 8 and 9 (not shown), and the fluid used may be sulphur hexafluoride, selenium hexafluoride, or one or both of these mixed with air, carbon dioxide, argon, helium or nitrogen. Alternatively, air alone may be used or a liquid such as oil. The current-carrying capacity may be increased by connecting the interrupter contacts in parallel with main contacts which do not break the arc.

Title: Improvements in cylinder grinders
IPC: B24B33/08
Filed: 1928-01-16
Abstract: 296,619. Hutto, M. C. Jan. 16, 1928, Round holes, enlarging and trueing; rotating- tool apparatus.-A cylinder grinder comprises a number of radially disposed abrasive blocks 18 urged inwards by garter springs 34 and abutting against lugs 31 on the edge of plates 28a fixed in radial slots in top and bottom rings 2 integral with the. body 1, each plate having tapered projections 29, 30 abutting against a pair of cones 5, 6 which are hand adjusted towards each other against spring pressure 9 by the screw and head 8 to force the blocks 18 outwards against the cylinder walls. If the cylinder walls are out of the true circular one end of the stone may be thus tilted in and the other end out, which causes the two cones to move axially as one element along the base to a new position of bearing pressure, and so allowing freedom of the stones to adjust themselves and so prevent them binding. When the blocks have ground themselves free they are again adjusted by screwhead 8. To hold the plate 28a in position without material longitudinal movement hardened pins 24 and 25 with countersunk heads are inserted near the end of each slot in the ring, the pins abutting against the high points 27 on the sides of the plate to allow the plate to tilt. The stone carriers have projections 19 with rounded ends which fit between the rings 2, 3.

Title: Improvements in motor devices for colour-light signals
IPC: B61L5/18
Filed: 1936-01-16
Abstract: 453,737. Railway light - signals. GENERAL RAILWAY SIGNAL CO., Rochester, New York, U.S.A.-(Assignees of Field, O. S. ; 473, Seneca Parkway, Rochester, New York, U.S.A.) Jan. 16, 1936, No. 1487. Convention date, Feb. 21, 1935. [Class 105] [See also Group XXXV] In a colour-light signal with a colour screen positioned by a motor element comprising a magnetic structure with pole faces cooperating with sector vanes transversely mounted on a rotatable armature shaft the vanes are arranged to lie on the same side with respect to the pole faces, for example at the left-hand side in the longitudinal direction of the armature shaft. The magnetic structure shown consists of two U-shaped members 27, 28 magnetized by permanent magnets 31 so as to provide at the front and rear of the structure a pair of pole faces 27<1>, 281 with which co-operate front and rear vanes 7, 8 mounted on a rotatable armature shaft which can be normally or reversely energized by a winding (not shown in the Figure) and is thereby moved in the clockwise or anti-clockwise direction. The axial component of the force on the lower vane 7 will act axially towards the right and therefore its turning moment will tend to pull the adjacent end of the shaft down on to its knifeedge bearing 10. The axial component of the force acting on the upper vane 8 also will act axially towards the right and therefore its turning moment will tend to push the adjacent end of the shaft on to its knife-edge bearing 10a. The rear pole faces are cut to provide inwardly set ears 35 which give a direct pull on the vane 8 as it reaches its limit positions to provide extra torque for effective closure of the usual contact springs, Fig. 5 (not shown). The armature is biassed to its central deenergized position by links having a slotted connection with pivoted counterweights, Fig. 5 (not shown). Specifications 275,942, [Class 75 (iv)], and 379,776 are referred to.
