Title: Improvements in or relating to starting apparatus for internal combustion engines of aircraft and other vehicles
IPC: F02N99/00
Filed: 1939-06-04
Abstract: 529,553. Turning-gears. BOSCH GES., R. June 3, 1939, No. 16342. Convention date, June 30, 1938. Drawings to Specification. [Class 7 (v)] In a starter for aircraft, motor-vehicle and other engines, a coupling element is rotated manually or by a motor through reduction gearing and a friction clutch and is automatically brought into engagement with an engine member by means of a member which is connected to the coupling member through a friction coupling and by virtue of a higher speed of rotation than the coupling member exerts an axial and torsional thrust on the coupling member to urge it forwards into engagement with the engine member. The construction is the same as that described in Specification 529,552.

Abstract: 907,690. Sorting by gauging. ZKL VYZKUMNY USTAV PRO VALIVA LOZISKA. May 11, 1960, No. 16688/60. Class 106 (2). An automatic machine for sorting articles according to the diameter of a surface of revolution comprises a continuously rotatable feed disc with recesses in its periphery, a feed station, a measuring station, a plurality of sorting stations arranged around the feed disc and control means to open the entrance to a sorting station selected in accordance with the size of the article. As shown (Fig. 1) a rotating disc 1 has recesses 2 into which test pieces 6 are fed by means (Fig. 2) of a vertical tube 7 a rotating disc 8 and a stop 8a. The test pieces are passed between a fixed contact 9 (Fig. 4) and a movable contact 10 on an arm 12 pivoted at 13 and urged towards the fixed contact 9 by a spring 14.

Title: Improvements relating to hardening iron alloys by quenching
IPC: C21D1/56
Filed: 1936-06-18
Abstract: To moderate the hardening effect of a liquid used for quenching the surface of a heated iron alloy article, air or another gas, such as nitrogen or carbon dioxide, is introduced into the quenching liquid in the form of finely distributed bubbles.  The air or other gas may be enclosed in the foam produced by adding a foam-former, such as soap, saponin or glycerine, to the quenching p  liquid and may be introduced into the liquid or the soap or solution by means of a water-jet pump.  Instead of water chlorinated hydrocarbons such as carbon tetrachloride or trichlorethylene may be used as the quenching liquid.

Title: Improved means for counting knots and the like in yarn and like thread-like material
IPC: D01H13/32
Filed: 1960-05-13
Abstract: 895,515. Spinning and testing yarns. SOUTH AFRICAN WOOL TEXTILE RESEARCH INSTITUTE. May 13, 1960 [May 14, 1959], No. 16990/60. Class 120(3) An indicating device which may be mounted on a textile machine to check the efficiency of the machine and/or the operator, continuously and successively registers the occurrence of thickened portions such as knots or slubs in a running yarn without interrupting the yarn travel. Separate electromagnets actuate indicating circuits and reset the device on completion of a yarn investigation. As shown, passage of a yarn I through a slit 12 permits a spring 11 to retain a pivoted lever 2 in a position whereat a contact 8 bridges spring-loaded points 9 to maintain a circuit for energising electro-magnet 14: a knot will deflect the lever sufficiently to open the circuit between points 9 and then slide over the top of slit 12 between arms 13 to allow lever 2 to resume normal position and enable yarn to pass again through slit 12. When, at the commencement of an investigation, the electro-magnet is energized, an armature portion 15 is drawn against fixed portion 16 and causes a rod 18 to tilt a lever 19 about a spindle 20 and lift a pivoted slide 22 in a guide 23 to cause a flanged-extension or pawl 28 to engage a tooth of a ratchet wheel 29 which is thereby rotated to lift an arm 35 from a stop 48 into the starting position. When the electro-magnet 14 is deenergized, slide 22 falls or is lowered and is pulled to a position against a flange 24 by a spring 34 so that, when electromagnet 14 is automatically reenergized, pawl 28 again rises and rotates wheel 29 an amount limited by engagement of extension 30 with a ratchet tooth but sufficient to cause a plate 36 carried on insulated arm 35 to bridge a first set of contacts 37a, 37b, to complete an indicating lamp circuit, and so register the passage of a knot. The action may recur until expiration of the yarn and/or until all indicating lamp circuits have been successively operated, after which latter the occurrence of further knots will result in pawl 28 rising and falling harmlessly and ineffectively in a blank region 60 of the ratchet. On completion of the test, the electro-magnet 14 is deenergized (to free slide 22) and an electromagnet 39 raises an extension 43 of an armature 42 into engagement with a projection 47 (irrespective of the extent by which wheel 29 has been rotated) to rotate wheel 29 until arm 35 is arrested by stop 48, whereat the device is reset in preparation for the next test. The resetting may be automatically initiated, e.g. from a ball-winding machine. The movements of wheel 29 are restrained by adjustable friction means, Fig. 5 (not shown).

Title: Improvements in or relating to catalyst and processes for its manufacture and use
IPC: B01J23/882
Filed: 1955-06-20
Abstract: A refractory metal oxide carrier supports a minor proportion by weight of a catalyst composition comprising boron oxide; a compound of molybdenum and a compound of iron, cobalt or nickel; the amount of boron oxide in the catalyst being smaller than the total amount of the compounds of molybdenum and the iron group metal.  The catalyst composition can be shaped, pelleted or moulded to any size for use with all types of reactors such as fluidized and fixed bed reactors. The catalyst can be used both in the liquid and gaseous phase for the removal of undesirable impurities from gasoline or other hydrocarbon fractions; destructive hydrogenation of hydrocarbons, especially higher boiling oils; the reforming of gasoline; the dehydrogenation of normally gaseous or normally liquid hydrocarbons; isomerization of olefinic, paraffinic, alkyl aromatic and naphthenic hydrocarbons and the isomerization of alcohols and ethers; hydrogenation of unsaturated acids, alcohols and ethers; nondestructive dehydrogenation of unsaturated hydrocarbons; hydrogen transfer reactions; alkyl transfer reactions; the cyclization of aliphatic hydrocarbons containing six or more carbon atoms with straight chain arrangements; hydrocracking of higher boiling oils; desulphurization of kerosene, gas oil and lubricating oil and polymerization reactions; generally in the range of temperature of 300 DEG  to 1200 DEG  F.  Particularly exemplified is the removal of sulphur, arsenic or nitrogen from a hydrocarbon fraction comprising gasoline hydrocarbons by subjecting said fraction at a temperature of 500 DEG to 900 DEG  F., a pressure of 50 to 5000 pounds per square inch in the presence of hydrogen in an amount of 20 to 10,000 cubic feet per barrel of said fraction (or up to 25,000 S.C.P. in the case of a cracked feedstock) to contact with the catalyst of the invention at a L.H.S.V. of 10.  Preferred carriers are oxides of aluminium, zirconium, zinc, titanium, magnesium, thorium or silicon, naturally occurring oxidic materials such as clays, diatomaceous earth, feldspar or bauxite or mixtures of the oxides such as aluminium, and titanium; aluminium and silicon; aluminium and zirconium; aluminium, silicon and zirconium; aluminium and magnesium; aluminium, silicon and magnesium; zinc and zirconium; zinc and magnesium.  The boron compound is preferably boron oxide or boric acid.  The catalyst may be treated with one or more halogens, preferably fluorine.  Details are given of all the alternative methods of introducing the various components into the composition.  The catalyst may be regenerated by treatment with air or other oxygen-containing gases at temperatures below 1200 DEG  F. and this may be followed by a treatment with a hydrogen-containing gas at a temperature of 700 DEG  to 1100 DEG  F. or the regenerated processes may be reversed so to treat with hydrogen first.
