Title: Devices for controlling the depth of an object moving submerged through water
IPC: A01K73/02
Filed: 1968-02-23
Abstract: 1,148,158. Water kites. MT. AUBURN RESEARCH ASSOCIATES Inc. 23 Feb., 1968 [23 Feb., 1967; 6 June, 1967], No. 8906/68. Heading B7A. [Also in Division A1] A device for controlling the depth of an object moving submerged through a body of water, i.e. fishing nets or oceanographic instruments comprises a bridle 12 connected at its forward end to a tow cable 34 and with its legs 14, 16 respectively pivoted on shafts 18, 20 between which legs are mounted Venturi tubes 22, 24, end plates 26, 28, and a hollow cylinder 30. The end plates 26, 28 support between their upper portions a float 36 and between their lower portions a weight 38, both weight and float being symmetrically streamlined so as not to produce lift forces other than by their buoyancies. The portion of cylinder 30 directed away from the direction of movement through the water is perforated, and a flap 40 adjacent the perforations is movable in slots 46, 48. In operation, water flows over and under the cylinder and parts from its surface at flap 40. The Venturi tubes 22, 24 keep the pressure inside the cylinder below the ambient water pressure at the cylinder's surface so that the boundary layer of water is drawn through the perforation. Adjustment of flap 40 below the horizontal plane produces upward lift, raising the object 50, and vice versa. Plates 26, 28 reduce water flow around the ends of the cylinder, thereby increasing lift forces. The float 36 and the weight 38 maintain the stability of the device, which has no effect on the depth of the object 50 so long as flap 40 is in the horizontal plane of the cylinder axis. Alternatively, the device comprises a rotor (108), Figs. 4 and 5 (not shown) which is reversibly drivable at different speeds, having end plates (110), (112) to reduce water flow around the ends, and mounted in bearings (68), (70) holding bridle arms (64), (66) and arms (88), (90) which carry a float (92) and arms (94), (96) which carry a weight (98), the float and weight having the same purpose as in the first embodiment. Rotation of the rotor in one direction produces upward lift and vice versa.

Title: Improvements relating to the purification of organic liquids
IPC: B01D3/36
Filed: 1942-06-29
Abstract: 576,302. Distilling alcohols &c. STANDARD OIL DEVELOPMENT CO. June 29, 1942, No. 8920. Convention date, Aug. 1, 1941. [Class 32] In the dehydration and purification of organic liquids which contain impurities difficult to remove by simple distillation, e.g., the purification of alcohols prepared from olefines by treatment with sulphuric acid or of ketones, esters, chlorhydrins and amines by adding an entrainer which forms ternary azeotropic mixtures with the organic liquid and with a third liquid, e.g., water, the organic liquid containing impurities is fed to a fractionating column 2 at an intermediary level through a conduit 1, while the entrainer and third liquid is fed through conduit 4, 5 immediately above and below the conduit 1. The fractionating column is maintained at the required distillation temperaure by a steam coil 3 so that impurities, entrainer. and water are removed overhead through the line 6 while the purified organic liquid is drawn off continuously as a bottom fraction through conduit 16. The overhead distillate is condensed, stratified in decanter 9, and the upper layer is returned in part as reflux to the column while the lower layer is passed to a second distillation column in order to recover the entrainer and organic liquid from the aqueous content. The process is described specifically in respect to the recovery of secondary butyl alcohol from a mixture containing also secondary butyl ether and hydrocarbons as impurities using diisobutylene as entrainer.

Abstract: 722,201. Controlling vehicles. TWENTYMAN, C. E. H. July 10, 1953 [April 10, 1952], No. 9164/52. Class 79(5). [Also in Group XXXIV] In brake actuating means for tractors and the like where the brakes are applied and released through a pedal-operated lever which carries a pawl for engagement with a fixed rack and which is adapted to be displaced to its brakeapplying position by the driver of the vehicle and adapted to be held in that position by engagement of the pawl with the ratchet, there is secured to the lever an arm which extends therefrom to the vicinity of the driving seat so as to adapt said lever for manual operation also, and there is located on said arm, adjacent the driver, an auxiliary lever which, when swung into one of two extreme positions, operates through a linkage system and a cam positively to retain and lock the pawl in engagement with the ratchet. Fig. 1 illustrates the brake operating lever 1 in its inoperative or " off " position. The lever 1 is provided with a laterally projecting pedal 3 which when depressed actuates the lever 1 about its pivot 2 to apply the brakes. The lever 1 may also be actuated by depressing the arm or hand lever 8. Having applied the brakes, the driver may take the pawl 6 into engagement with the fixed ratchet plate 4 to retain the lever 1 in the " on" position either temporarily by depressing the spring-loaded plunger 13 by hand or permanently by swinging the auxiliary lever 19 from the idle to the working position. The action of the auxiliary lever 19 is shown in enlarged scale in Fig. 3 ; so that when the lever 19 is moved to the locking position, illustrated in full lines, a cam-like projection 20 is moved to strike and ride along the rounded shoulder 21 on the upper edge of a rocket member 16 and causes the rocker to turn in the direction which depresses both rods 15 and 17. The depression of the rod 15 pulls down the plunger 13 whereas the depression of the rod 17 turns the cam 18 about its pivot to engage the pawl 6 with teeth 7 of the ratchet plate 4. When it is desired to release the brake, the auxiliary lever 19 must be swung to the position shown by the chaindotted lines in Fig. 3 and a slight depression given to the lever 1 will enable the pawl 6 to assume the vertical position shown in Fig. 1 and release the brake operating lever 1.
