Title: A process for the production of low-boiling oils from higher-boiling oils
IPC: C10G11/04
Filed: 1936-12-28
Abstract: Oils are converted into products of low boiling point by treatment in the vapour phase with steam, water gas or other gases containing oxygen at temperatures above 350 DEG  C. and pressures up to 20 atmos. in presence of mixed catalysts which contain at least one oxidizing constituent comprising magnesium, calcium, zinc or oxides or phosphates of these metals or of iron, at least one hydrogenating constituent comprising aluminium, tin, vanadium, molybdenum, tungsten, manganese, iron, cobalt, nickel, or sulphides of these metals or of zinc, and carbon as a catalyst activator.  Additional catalysts which exert a cracking action, e.g. aluminium oxide or molybdenum oxide; a polymerizing action, e.g. organic and inorganic halides or lead; a condensing action, e.g. gaseous halogen compounds, may also be used.  The catalysts may be pretreated with air.  The materials undergoing reaction may be indirectly heated by heat exchange with the products of the reaction which latter have been further heated directly or indirectly by a separately heated agent, e.g. steam.  The initial materials comprise petroleum tars and their distillation, cracking and hydrogenation products and oils derived from coal, shale, peat, wood, bitumen, humin substances, lignin, &c., by distillation, cracking or hydrogenation.  Heavy oils are preferably pretreated in the liquid phase and then subjected to the vapour-phase treatment which is preferably commenced at high temperatures, e.g. 450 DEG  C., and completed at lower temperatures, e.g. 350 DEG  C.  The reaction temperature may be controlled by the introduction of ammonia or ammonia salts.  Eddesser petroleum is cracked at 450 DEG  C. in presence of molybdic acid and steam under 100 atmos. pressure and passed into a separator from which liquid fractions are re-cycled.  The products in the gaseous state are treated at 500-550 DEG  C. with 1 kg. steam at about 20 atmos. in the presence of 40 parts magnesium oxide, 40 parts molybdenum oxide and 20 parts carbon, 0,9 kg. gasoline boiling up to 180 DEG  C. being obtained.

Abstract: 766,294. Cleaning endless conveyer belts ROBERTSON, J. D. Dec. 13, 1954, No 36031/54. Class 78 (1). [Also in Group VIII] Apparatus for cleaning a travelling conveyer belt made of flexible material having interstices therein whose sizes vary with lateral contraction and expansion of the belt comprises a plurality of members which operate in succession on the belt at longitudinally spaced locations to laterally contract and expand the belt in turn to close and open the interstices, whereby foreign matter is dislodged, and means for directing a wash spray on the belt after its lateral expansion and while its interstices are open to wash the loosened foreign matter from the belt. As shown, a conveyer belt or " felt " for use in a paper-making machine'and consisting of either woven sheet material or perforated flexible plastic sheet material is engaged successively by curved-axis rollers 40, 42 and 44, the planes of whose axles 56 are adjustably inclined to adjusting the ends of the axles in bearings 78, 80 and 82 respectively. The arrangement is such that the belt first engages the concave side of roller 40 and leaves it on the convex side thus expanding the belt laterally and opening the interstices or perforations to loosen the foreign matter in them. The belt is then contracted laterally by roller 42 whose convex side first engages the belt and is then expanded laterally again by rollers 44 whose concave side first engages the belt. Roller 44 is adjusted to give a greater degree of expansion than roller 40. A wash spray 46 at high pressure is positioned at the back of the belt as it leaves roller 44 with its interstices or perforations expanded to act through the belt on the loosened foreign matter, and is followed by an inclined spray 48 at less pressure acting on the front of the belt. Each roller is built up from a number of spools 53, Fig. 4, carried by ball bearings 54 which are slid along the axle 56 which is of hexagonal section, being spaced by sleeves 58, and a rubber covering sleeve 52 which is engaged over the spools after assembly. The spools are held in place by end plates 60 secured to the axle by set screws 62. A cap 66 is secured to the flange 53a of the end spool and rotates on a flanged member 72 fixed to plate 60 by screws 74 passed also through a rubber seal 74 so that the latter is pressed around the axle. The roller 42 is vertically adjustable on uprights 86 to vary the angle of lap of the belt around it, and roller 40 may also be adjustable along the support 84 for tensioning the belt by means of screwed rods (Fig. 9, not shown) engaging nuts carried by the bearings 78 and simultaneously rotatable by a hand wheel, clamping means being provided for locking the bearings in their adjusted setting.

Title: Dolls
IPC: A63H13/00
Filed: 1975-09-02
Abstract: 1517187 Dolls TOMY KOGYO CO INC 2 Sept 1975 [4 Sept 1974] 36164/75 Heading A6S A doll has a leg mounted upon a base and containing a shaft driven through mechanism mounted in the base to move a jointed part, e.g. its other leg &c. while the first leg is held stationary on the base, the first leg alternatively being rotatable on the base so that the mechanism twirls the doll as a whole. A hollow base 12 contains a flexible shaft 36 rotated by turning a handle 48 to drive through gears 54, 56 to a shaft 102 within the doll's leg 86. A lever 20 journalled by trunnions 22 in the base 12 is biassed by a slider button 66 to raise the right-hand end of the shaft 36, the gears 54, 56 and the shaft 102 so that dogs 82 on the foot of the doll are raised clear of slots 84 within a socket on the base. Accordingly, rotation of the shaft 102 acts through a friction slip coupling 106, 108 to twirl the, doll as a whole on the base 12. If the slider button 66 is moved leftwards to allow cam surfaces 34 and the left-hand end of the lever 20 to rise by pivoting about its trunnions 22, its right-hand end together with the gears 54, 56, &c., falls. Accordingly the dogs 82 on the doll's foot slide into slots 84 inside the socket on the base 12, and the doll as a whole is thus prevented from twirling on the base. If the shaft 102 is now rotated by turning the handle 48, the coupling 106, 108 slips. Drive is transmitted instead through gears 112, 114 and a slip coupling 146, &c. to the jointed leg 94, 96 which is pivoted backwards or forwards relative to the doll's torso 88 by an amount limited by stops, and to the doll's torso which is rocked backwards or forwards relative to the leg 86 by an amount limited by stops. Simultaneously, the shaft 102, &c. drives through gears 122, 124; 130, 132 to friction slip couplings 138, &c. for rotation of the doll's arms 92. When a desired posture of the doll has been achieved the slider button 66 is returned to the position shown and turning the handle 48 causes the doll once more to twirl, thus simulating a ballerina.

Dec. 5, 1930, No. 36783. Convention date, Dec. 5, 1929. Void [Published under Sect. 91 of the Acts]. [Class 63.] Ironing.-A hat-ironing machine comprises a rotary turntable 2 supporting a hat block, a rocker arm 16 mounted on a rock shaft 12 intersecting the axis of the turntable, and a smoothing iron 11 attached to a carrier movably mounted on the rocker arm and resiliently pressed toward the hat for the purpose of ironing the hat by to-and-fro movements of the rocker arm. The rocker arm is actuated by a revolving crank through an adjustable coupling enabling the range of movement of the iron to be varied for particular parts of the hat. The spindle 3 of the turntable is driven by an electric motor through worm gearing, and itself carries a worm driving one member of a clutch 50, disengaged, when desired, by a handle 55. The other member of the clutch is connected by a spring 42a to a crank 41 connected by a link 43 with an arm 15 on the rock shaft, the connection being adjustable along the arm. The rock arm 16 pivotally carries an arm 17 terminating in a handle 26. This arm carries a yoke 23 pivotally carrying a yoke 21 supporting the iron 11, the two yokes providing a universal joint. The iron is urged toward the hat by a spring 18, and the weight of the parts, when the iron is operating on the crown, is counterbalanced by a spring 28 secured to an extension of the arm 17 and to a bracket below the rock shaft. For holding the iron in inoperative position, a latch 24 on the arm 17 engages a latch plate fixed to the arm 16, the latch being released, when desired, by a lever 25. A further counterbalanced spring 31 is operative when the iron is operating on the sides of the crown. For operating on the brim, the hat is inverted on a brim block, substituted for that shown, and the coupling on the arm 15 is shifted to near its end. The spring 42a functions as the iron is passing over the corner of the brim or crown, to accelerate its movement and prevent burning.
