Title: Production of polymerized resin acid derivatives
IPC: C09F1/00
Filed: 1941-11-12
Abstract: 557,512. Polymerized resin acid derivatives. HERCULES POWDER CO. Nov. 12, 1941, No. 14584. Convention date, May 3, 1941. [Class 2 (iii)] Polymerized resin alcohols are prepared by treating a polymerized resin acid, an ester thereof, polymerized rosin or an ester thereof with hydrogen, so as to reduce the carboxyl group of the starting material to the primary alcohol group. According to conditions, polymerized resin alcohols or polymerized hydrogenated resin alcohols are obtained. Reduction may be accomplished by treating the starting material with an alkali metal and a lower aliphatic alcohol, and thereafter hydrolysing the resulting alcoholate to the alcohol, or the starting material may be reacted with hydrogen in the presence of a conversion catalyst, thereby producing a polymerized hydrogenated resin alcohol. Many starting materials are specified, and examples are given in which:-(1) the methyl ester of polymerized rosin is treated with metallic sodium and anhydrous n-butyl alcohol ; (2) the methyl ester of polymerized d-pimaric acid is treated with metallic sodium and anhydrous n-butyl alcohol; (3) polymerized abietic acid, in solution in dioxane, is heated in a pressure bomb with hydrogen in the presence of a copper chromite catalyst ; (4) the methyl ester of polymerized sapinic acid is treated as in example (3) ; (5) the dimer of abietic acid is treated as in example (3) ; (6) the dimer of abietic acid is treated as in example (1).

Abstract: 544,155. Catalytic dehydrogenation and hydrogenation. KELLOGG CO., M. W. Sept. 27, 1940, No. 14648. Convention date, Oct. 3, 1939. [Class 1 (i)] [Also in Group IV] Motor fuels of high anti-knock value containing a high percentage of naphthenic compounds and free from olefines are obtained by passing a naphtha fraction boiling within the gasoline range and consisting mainly of aliphatic hydrocarbons together with hydrogen over a dehydrogenating-aromatising catalysts at temperatures between 800 and 1000‹F., under pressures of 1-30 atmos. and with a space velocity of less than two volumes of liquid naphtha per volume of catalyst whereby the naphtha is converted into aromatic and olefinic hydrocarbons and gases, separating the normally liquid products of the reaction from the gases and passing the liquid products with hydrogen over a hydrogenating catalyst at 200‹F. 20 atmos. pressure, and a space velocity of 0.25 volumes of liquid per volume of catalyst per hour, whereby the aromatic hydrocarbons are hydrogenated to produce naphthenic hydrocarbons and the olefines are hydrogenated to yield saturated compounds. The aromatisation catalyst specified comprises oxides of metals of the 6th Group of the Periodic System together with oxides of metals of the 3rd Group, e.g. catalysts prepared by depositing 10 per cent. chromium oxide on activated alumina or by co-precipitating molybdenum and aluminium oxides. The catalyst used in the second stage is the same as that used in the first stage or catalyst produced by soaking silica gel or pumice in nickel nitrate and then igniting the mixture to convert the nickel to oxide which is reduced to nickel by treatment with hydrogen. Ten per cent. copper may be added to the nickel. Hydrogen from the second stage after purification may be re-cycled to that stage.

Class 145 A structural or reinforcing ring, particularly a reinforcing ring for silos as described in Specification 748,179 [Group X], is composed of two or more layers 11, 12, 13, 14 of plywood and one or more layers 8, 9, 10 of wood of a thickness considerably greater than the individual layers of plywood and is built up from arcuate elements 2<SP>0</SP>, 2<SP>1</SP> &c. assembled together with staggered butt joints 15 and bonded together by means such as adhesive. The arcuate elements are made by attaching plywood to opposite faces of an inner layer of softwood by such means as a resin bonding agent set by radio frequency heating, cutting a required number of elements 2<SP>0</SP>, 2<SP>1</SP> &c. from the sheet and dividing each element along a plane extending midway through the softwood layer. The elements are then assembled, in staggered relation and with plywood and softwood layers alternating, and bonded together by means of, for example, a resin bonding agent and suitable heat-treatment. A steel band may he secured to the outside of the ring by bonding or by screws and may be split so that it can be tightened on the ring by a screw or have overlapping ends interconnected by welding or by screws.

Filed: 1922-05-31
Abstract: 183,430. Trent Process Corporation, (Assignees of Trent, lV. E.). July 20, 1921, [Convention date]. Flotation processes and apparatus.-A process of treating finely-divided coal or other carbonaceous material consists in placing the material in water or other liquid suspension, applying an agglomerating-agent such as hydrocarbon oil, and agitating the mixture to cause the oil to unite with the coal particles to form substantially uniform spherical masses free from gangue and largely freed of the liquid and of such sizes as to be capable of being carried by the moving liquid. The finely pulverized coal is fed with water intermittently or continuously through an inlet 2 of the receptacle 1, which is divided by the partitions 5 - - 8 into compartments 4, 9, 10, 11, 12, the inlets and outlets 16 - - 19 of which are so placed and of such a size as to regulate the time required for the material to pass through each compartment. Oil is introduced by the pipe 3 and is agitated with the coal and water by means of the blades 15 on a rotary shaft 13. The agglomerated masses are carried by the water through the discharge trough 20, and deposited on an endless travelling screen 21, where they become subjected to the clearing action of jets of water from the pipe 26 and from which they are discharged into the receptacle 23. The water, with the suspended impurities and any excess oil, flows through the screen 21 into the trough 24, being conveyed by a pipe 24<1> to a settling-receptacle 25. Specification 151,236 is referred to. The Specification as open to inspection under Sect. 91 (3) (a.) refers also to Specification 146,981 but this reference does not appear in the Specification as accepted.

Produce from an extrusion nozzle is cut off by a converging stream of gas from a chamber concentric with the nozzle. The control of the gas stream is effected by a valve synchronized with the produce extruding means. In the form shown in Fig. 3 a rotatable valve 23 directs produce into a chamber 21. The valve is rotated to connect the chamber with extrusion nozzle 26 and piston 20 moves to force the produce through the nozzle into, e.g. containers. As the piston reaches the end of its stroke, gas is injected through annular chamber 27 to cut-off the produce. In another form, Fig. 4 (not shown), produce, forced through an extrusion nozzle by a piston (30) is similarly cut-off by a gas jet at the end of the piston stroke. As the piston withdraws suction is created at the tip of the nozzle to draw remaining produce back into the head.

Title: Improvements in and relating to means for lowering boats
IPC: B63B23/18
Filed: 1920-06-08
Abstract: 168,970. Schat, A. P. June 8, 1920. Boat raising a n d lowering gear. - The running blocks of boatlowering tackle are provided with means for bracing the falls irrespective of the position or inclination of the boat, so that the falls may be payed out from the boat. The running block c, Fig. 1, is fitted with a lever e pivoted at f and fitted with a pivoted brakeshoe g for gripping the fall d. Self-locking blocks with braking means automatically actuated by the weight of the boat, such as those described in Specification 154,470, [Class 78 (v), Winding and paying-out apparatus &c.], may be used. The fall 42 passes under the sheave 34, around the sheaves 38, 35, and upward to the sheave 34, making a small angle of contact with the sheave 38. The sheave 38 is carried on a pin 37 working in a slot 36 and fitted to a link 40 pivoted to a lever 39 which is itself pivoted at 33 to the frame 30 of the block. When the boat is suspended from the hook 41, the sheave 38 automatically grips the fall between itself and the sheaves 34, 35. This braking effect is controlled by the lever 39. In another modification, Fig. 4, the hook 5 is suspended by links 6 mounted on a brake shaft 7 passing through vertical slots 8 in the side cheeks 1 in which the sheave 4 is mounted, the sheave axle 3 riding in vertical slots in the links. The brake shaft 7 is fitted with toggle links 12, 13 carrying brake shoes 14, 15, pivoted at 16, 17, and eccentrics 19 co-operating with projections 21 on the cheeks 1. When the boat is freely suspended from the hook 5, the shoes 14, 15 automatically move outward to grip the falls, and the braking effect may be regulated by the lever 7 mounted on the brake shaft.
