Title: Improvements in carburettors
IPC: F02M17/12
Filed: 1926-08-13
Abstract: 280,293. Richardson, T. H. O., and Richardson, J. W. Aug. 13, 1926. Spray carburettors.-To maintain the proportion of air to fuel constant, the fuel is supplied to the interior of a suction-actuated wing E mounted in an induction passage C of square cross-section, the wing being provided on the upper surface with perforations or slits F which atomize the fuel as it is drawn therethrough into the induction passage. The wing E is secured to the horizontal arm D<1> of an L-shaped fuel supply pipe, the vertical arm D of which dips into a, fuel reservoir B supplied from the float chamber A. The arm D<1> is provided with a fuel outlet slot on its upper surface opening into the interior of the wing, and is rotatably mounted in the wall of the reservoir B. A vane L may be provided on the bottom of the arm D to damp its movements. To control the movement of the wing, a spring G is attached at one end to a stop G<1>, which may be adjustable, and at the other to an arm K attached to the arm D of the fuel pipe. At starting, the wing is held bv the spring with its upper end in contact with the wall of the induction passage, air entering between the lower end of the wing and the opposite wall of the induction passage. As the suction increases, the wing assumes a more vertical position thus admitting additional air. Modifications are described in which the camber of the wing is adjustable. In one form, a bent spring M<1>, M<2>. Fig. 5, secured to a fixed rod L<1>, forms part of the wing, the hollow portion of which does not extend beyond the bottom of the pipe D<1>. As the wing moves under the influence of the suction, the arm M<2> of the, spring tends to straighten, thus automatically varying the camber of the under surface of the wing. In a second form (Fig. 6, not shown), the rod L<1> is free to move in the induction passage and is connected to the lower end of the hollow part of the wing by a strip of pliable metal, so that by manually adjusting the position of the rod L<1> the camber is varied.

Title: Improvements in the preparation of phosphorescent substances
IPC: C09K11/06
Filed: 1939-07-10
Abstract: 531,035. Luminescent materials. I. G. FARBENINDUSTRIE AKT.-GES. July 10, 1939, No. 20057. Convention date, July 18, 1938. [Class 39 (i)] [Also in Group IV] A phosphorescent material is obtained by incorporating coronene with solid polynuclear fully hydrogenated hydrocarbons; these may be hydrogenated anthracene, pyrene or coronene. The coronene content may be from 0.5 to 20 per cent. With a content of 1 to 3 per cent a yellow-green phosphorescence is obtained at ordinary temperatures which changes to blueviolet above 80‹ C. In one method of making such a material coronene is mixed with five times its amount of decahydronaphthalene and subjected to hydrogen at 200 atmospheres with tungsten sulphide as catalyst. The pressure is maintained by addition of hydrogen until the product still retains 1 per cent of coronene after which the remaining decahydronaphthalene is removed by distillation. In another methode pyrene is hydrogenated with tungsten sulphide as catalyst and 1 to 2 per cent of coronene is dissolved therewith in a mixture of benzene and alchohol, from which the material is crystallized.

Title: Improvements in combined vacuum and pressure brake control apparatus
IPC: B60T13/46
Filed: 1922-07-22
Abstract: 203,469. Gresham, H. E., and Kiernan, G. July 22, 1922. Fluid-pressure.-Valve mechanism for the control of a compressed-air brake on a locomotive by the train-pipe of automatic vacuum brakes provided on other vehicles of the train comprises a piston a constantly subject on its under side to the vacuum in the trainpipe connected at i and on its upper side to that in a reservoir connected at g. This reservoir is open to the train-pipe past a non-return valve b when the piston a is in the releass position shown. The valve b is contained in the train-pipe fitting i and seats upon the port h when the train-pipe pressure is raised to apply the brakes. The piston a is connected by the lever e to a piston valve c having radial apertures l extending from a central aperture k. In the release position shown the brake cylinder connected at x is open to exhaust through the passage k, l and chamber m. When the train-pipe pressure is raised, the compressed-air supply valve d is opened by the lever e and the valve c is also raised so that the apertures l are open to the chamber n and compressed air is thus supplied to the brake cylinder until the compressed-air pressure on the valve c is able to overcome the difference in pressure effected on the sides of the piston a. The degree of application of the pressure brake is thus proportional to that of the vacuum brakes.

Title: Organosilicon compounds and compositions containing same
Inventor: PATTON ROBERT
IPC: C08G77/00
Filed: 1964-05-14
Abstract: The reaction of Si-bonded hydrogen with an unsaturated compound, as hereinafter defined, is catalyzed by a complex of a Pt (II) halide with a compound containing S, N or P.  Any compound having at least one and not more than two H atoms bonded to an Si atom may be used, including monomers, polymers, copolymers and mixtures thereof.  A preferred compound is a substituted silane of formula RbSiHcX(4- bc), where R is hydrocarbon, X is halogen, alk- or aryloxy, b=0, 1 or 2, c= 1 or 2, and b + c does not exceed 4.  The phrase "unsaturated" embraces all those compounds containing a pair of C atoms linked by an unsaturated bond but excludes primary and secondary amines, aldehydic compounds and compounds having a CN group bonded directly to an unsaturated C atom.  If desired, the Si-H bond and the unsaturation may be embodied in the same compound, thus giving rise to a polymeric reaction product.  The Pt complexes used in the invention may have the formula L2PtX2, (LPtX2)2 or LL1PtX\2, wherein L and L1 are ligands containing S, N or P, and X is halogen, usually Cl.  Suitable ligands include hydrocarbyl phosphines, hydrocarbyl sulphides and nitriles.  Between 10-8 and 10-2 moles of catalyst (calculated as atoms of Pt) per mole of unsaturated reagent is used. Reaction temperature is best 10-150 DEG  C., and almost always below 300 DEG  C.; reaction time may be 1/2 -8 hr.; normal or superatmospheric pressure may be used.

Title: Improvements in or relating to engine cylinder and head connection
IPC: F02F1/04
Filed: 1943-12-02
Abstract: 572,456. Cylinder heads. UNITED AIRCRAFT CORPORATION. Dec. 2, 1943, No. 20192. Convention date, Oct. 30, 1942. [Class 7 (ii)] The head 14 of an engine cylinder, particularly of aluminium-base metal having a different co-efficient of expansion from the steel barrel member 10, is shrunk and screw - threaded on to the barrel member, and the respective threads 18, 16, on the head and barrel are cut to different pitches which become equal through differential expansion at a temperature within the range of operating temperatures. The fin muff jacket 12 is passed over the barrel threads 16 which are of rounded cross section. At the machining temperature the pitch 18 of the head members is made less than the pitch 16 of the barrel but at the shrinking temperature of the head the pitch 18 preferably becomes the same amount,greater than the pitch 16. For further provision against thread stresses the curvatures of the threads 16, 18 are not equal. This produces interference areas D at the crests and troughs of the threads and causes deformations as the mismatched thread portions are forced into continuous engagement by the forces of the shrink fit. By this means the stresses in the material are confined mainly to radial forces at the crests and roots and results in compression of the material. In some cases the interference may be less at the root of the aluminium thread in the head than at the crest thereof so as to reduce the stress at the root of the weaker thread.

Title: Humidifying system
IPC: F24F6/12
Filed: 1964-05-19
Abstract: 1,037,749. Air humidifying system; spray producers. GRINNEL CORPORATION. May 19,1964 [May 17,1963], No. 20673/64. Headings B1R and B2F. In an apparatus for maintaining the humidity in an enclosure a humidistat 44 when the humidity in the enclosure requires correction operates a 3- way valve 48 and serves to connect a line 58 which leads to a water tank 94 and an air manifold 14 to a source of air pressure 52 and air from manifold 14 and water from tank 94 are supplied to an atomizer nozzle 10 in the enclosure, the pressure of an supplied to the tank 94 being greater than the pressure of the air in manifold 14. Air is first supplied to line 50 through valve 48 and this pressure opens a valve 66 and connects air manifold 14 directly with air source 52 through a pressure reducing orifice 70. Air passing from line 50 through line 58 is at first vented through a port 74 of a valve 76 until the air pressure in manifold 14 reaches a predetermined value which closes valve 76 and air then passes to the tank 94. The nozzle 10 comprises a water valve normally closed but opening when the water pressure reaches a predetermined value, the system being so arranged that this pressure is reached more quickly than air pressure in manifold 14 is building up. When the humidity is restored valve 48 is actuated via pressure line in the system and vented through line 48alpha; valve 66 then closes and valve 76 opens. The nozzle 10 (Fig. 2, not shown) receives water from the tank 94 via line 16 and water enters a chamber 26 normally closed by a spring loaded valve 28 and opened when the water pressure reaches a predeterminated value. Water is being discharged through the orifice 34 and mixes with air from manifold 14 supplied via pipe 12 and passages 38 and 40 before final discharge from orifice 42 into the enclosure. In a modification the reaching of a predetermined pressure in the air manifold serves to open a valve for supply of air to the water tank and the water tank exhausts to the air manifold through the valve wherein the desired humidity in the enclosure has been reached and the valve connecting the system to the source of air pressure has been closed.
