Title: A process for the production of carboxylic acid esters
IPC: C07C69/24
Filed: 1958-01-02
Abstract: The invention comprises a process for the production of carboxylic acid esters, wherein the same limited quantity of one or more esterification catalysts in liquid form under the reaction conditions is continuously sprayed at high velocity within a reaction vessel to form a reaction zone which is filled by a layer of sprayed whirling particles of the liquid catalyst and is continuously recycled, while one or more carboxylic acids, anhydrides or esters is introduced into the reaction zone together with one or more alcohols, ethers or olefines.  The catalyst may be a liquid, or a solution, suspension or emulsion of a catalyst material (which may itself be solid) in an inert liquid; specified catalysts are hydrochloric acid, sulphuric acid, phosphoric acid, aliphatic or aromatic sulphonic acids (the latter may be molten), and acid salts such as zinc chloride or aluminium chloride, which may contain water of crystallisation and may be used as aqueous or anhydrous melts or as solutions or suspensions; specified inert liquids are natural or synthetic paraffins, silicone oils and mineral oils.  Suitable reactants are fatty acids such as formic, acetic, propionic, butyric, oleic, stearic, palmitic, and other saturated or unsaturated monocarboxylic acids, aromatic monocarboxylic acids such as benzoic and toluic acids, and dicarboxylic acids such as succinic, glutaric, adipic, suberic, azelaic, sebacic, phthalic, isophthalic and terephthalic acids; nonohydric alcohols and their ethers, polyhydric alcohols such as glycol and glycerol, and olefines such as ethylene, propylene and butylene.

Abstract: 161,268. Baumann, K., Guy, H. L., and Metropolitan-Vickers Electrical Co., Ltd. Jan. 5, 1920. T r a n s m i tting- mechanism ; fluid relays.-In valve-gear for turbines &c. wherein a number of steam admission valves 1, 1 are opened in sequence by a governor-actuated, spring-loaded, floating lever 5, means are provided for varying the sequence of opening by varying the distribution of the load on the lever 5. Thus, Fig. 1, by connecting the upper ends of the springs 9<a>, 9<b> to straps 11 embracing eccentrics 12 secured to pins 13 which are journaled in the lever 5 and are rotatable by handles 12<a>, either of the springs may be given the greater tension and so cause the later opening of its associated valve. In a modification the lower ends of the springs are secured to a lever, the inclination of which may be altered. Again, one spring only may be used, being attached to the lever 5 by a crank, which can be thrown from one side to the other of the point of attachment of the lever to its operating rod. An adaptation of the last modification to a turbine having four valves 1 is shown in Fig. 11, wherein three floating levers 5, 5a, 5b are used, and the three springs 9<e>, 9<f>, 9<g> are connected thereto by cranks 18.

Abstract: 984,128. Treating material in reactors. SOC. INDATOM. Jan. 3, 1963 [Jan. 18, 1962], No. 373/63. Heading G6C. An experimental facility 1 for irradiating materials in a reactor 2 is of cylindrical outline and adapted to be rotated by a vertical shaft 4 in an arcuate recess formed in the wall of the reactor tank. Other similar facilities may be provided as at 3a, 3b. As shown, the reactor is heavy-water moderated. The facility 1 comprises tanks 5, 6 containing heavy water and reservoirs 7, 8 containing light water acting as a thermal neutron absorber. The tanks 5, 6 have a test channel 9, 10 extending therethrough and as shown in Fig. 1 the channel 10 is in the position for irradiating the material whereas channel 9 is shielded from the reactor. The lower end of the facility is shielded by concrete plugs and water reservoirs (Figs. 2a, not shown) and the upper end, Fig. 2, is shielded by a water reservoir 21, a concrete plug 22 and a lead covered steel plate 23. The channels 9, 10 contain coolant fluid and are connected at their ends by conduits such as 26 to heat exchangers 25 in the plug 22. The exchangers 25 may be connected through conduits 27 and rotary joints 28 to fixed external heat exchangers (not shown) to further cool the fluid. In use, after the channel 10, for example, has been in the Fig. 1 position for a sufficient time the facility is rotated through 180 degrees and the channel 10 may then be left to cool before it is unloaded. Meanwhile, a further experiment may be begun with the channel 9 which is now in the radiation zone. A modified facility is described with reference to Fig. 6 in which a rotatable ring 51 has heavy water reservoirs 52, 53 separated by light water columns 54, 55. Test channels 66, 67 extend through the reservoirs 52, 53 and the ring 51 surrounds a fixed column having a heavy water compartment 56 and a light water compartment 57.

Each line pan of a double-chain scraper conveyer comprises an end casting 1 provided with first and second lugs 13, 14 and an end casting 4 having a lug 18. A connector member 20 having a central slot 21 is engageable over the lugs 13, 18 and is secured by a semi-cylindrical locking member 28 which is inserted by rotating it around the lug 14. Fig. 2 shows how, by suitable shaping of the lugs 13, 18 and of cooperating faces (26, 27, Fig. 6, not shown) of the connector member 20, a horizontal hinging action may take place between adjacent pans. Faces 22, 23 of the member 20 are tapered to permit hinging of the pans in a vertical plane. To remove a line pan from the assembly without disturbing the remainder of the pans, the four locking members 28 securing the pan are removed, as are the corresponding connector members 20. The pan is then lifted as shown in Fig. 13 and slid until overlapping portions of the pan and the adjacent pan at the opposite end of the lifted pan are clear of each other. The members 1, 4 may be other than cast.

The speed of swing- ing of the dragline platform also is controlled in accordance with the angle of swing so that the cycle of excavating and dumping can be automatically repeated after the initial points of the cycle have been recorded in a calculator means. In the arrangement shown the hoisting transducers are mechanically connected to the hoisting mechanism 2 driven by motor 35 and the dragging transducers are connected to drag rope mechanism 4 driven by motor 37 and the swing angle transducers are connected to swing motor 39. The transducers are connected to units 31, 32, 33 respectively which control the motor controllers 34, 36, 38 and various adjustable preset controls are provided and all signals are computed in the calculator 26. A protection system is provided which ensures that the bucket will not prematurely dump its load nor approach too close to the dragline structure. In operation an operator manually performs a digging operation and records the transducer outputs of the breakout point, dumping point and digging contact point so that the calculator is programmed for repeated digging and dumping cycles. The various details of the operation are described in connection with a digging profile shown in Figure 10. The excavator can be made to operate in a 360‹ mode.

Abstract: 269,628. Lister, P. Jan. 13, 1926. Reeds, threading.-The reed is held by adjustable clips in a horizontal position on the platform of a stand a, b, b<1> furnished with a foot treadle w for driving a rod h loosely carrying a circular metal blade m furnished with a groove m<1>. The rod h is so shaped as to rotate the blade m. Warp threads placed in this groove are drawn through the reed dents, the blade m having a rim n, which causes long lengths of threads to be drawn. The blade and rim are divided at o<1> to make an opening, o, the width of which is adjusted by a screwed spindle t<1> operated by a worm and worm wheel p<1>. The width of the opening is shown on an indicator r fixed. to the spindle t'. The opening o causes the blade m to traverse from one dent of the reed to the next as the rod h rotates, a balance weight assisting this movement. When the treadle w is depressed, a lever g linked thereto operates a chain e passing round a gear c and attached to a spring-controlled drum f. The gear c is attached to a free-wheel gear c<1>. which turns a gear d and rotates the rod h. This makes a full revolution, upon which a catch l coacting with a cam k fixed to the rod h blocks further rotation of this rod h and prevents further depression of the treadle. When the treadle rises, the gear c is rotated, but owing to the free-wheel arrangement the gear c<1> is not turned. A lever g<1>, however, moves the catch l out of its locking position into the position shown in Fig. 3, thus freeing the rod h for a further rotation when the treadle w is again depressed. A catch l<1> prevents back play of the rod. Balancing springs are provided on the bar carrying the pulley f. Specifications 5487/82, 17562/99, 15503/04, and 25012/06 are referred to.
