Abstract: 420,811. Spray carburetters. CARTER CARBURETOR CORPORATION, 2838, North Spring Avenue, St. Louis, Missouri, U.S.A. April 28, 1933, No. 12458. Convention date, May 12, 1932. Addition to 420,810. [Class 7 (iii)] [See also Group XXIX] According to the invention of the parent Specification an eccentrically - mounted choke valve in the air inlet of a carburetter has its initial opening resisted until a predetermined degree of suction is attained, whereupon the valve releases itself and moves freely towards fully-open position. According to the present invention, the initial opening movement is resisted by a drum member yieldablyconnected to the choke valve by a spring and adapted to be engaged by a latch, and means are provided for disengaging the latch when the air choke valve is opened to a predetermined position. One end of a bimetallic coil 30, Fig. 5, is secured to a shaft 31 carried by a housing 32 fixed to the exhaust manifold 12, and the other end 36 engages an adjustable abutment 37 secured by a screw 39 in a slot 38. After the coil has allowed the choke valve to open fully, the end 36 of the coil moves out of engagement with the abutment 37. A lever 42, Fig. 2, on the shaft 31 is connected by a link 44 with an arm 43 rigidly secured to the shaft 8 of the choke valve 7, and a cam 48 mounted on the shaft 8 is connected to the arm 43 by a screw 50 passing through a slot 49. A drum 51 is mounted on the shaft 8 between the cam 48 and the carburetter wall, and is provided with a slot 55 which is engaged, when the engine is stopped and the temperature is low, by a spring-pressed latch 56 mounted on a pin 57. When the engine starts, the suction opens the valve 7 against the resistance of the coil 30 and a spring 52, one end of which is connected to the shaft whilst the other end is engaged in one of a plurality of slots 54 in the periphery of the drum, until the cam 48 passes under the latch 56, and releases the valve. To open the choke valve when the throttle is moved to a wide-open or fully-closed position from a partly-open position, the throttle shaft 24 is provided with a lever which is connected to the lever 43 by a link 63 and a lost-motion device. The throttle valve operates a metering- rod to control the amount of fuel passing to the main nozzle 22 and the slow-running nozzle 25, which discharges at the edge of the throttle valve, and an accelerating-pump which discharges through a separate nozzle into the mixing-chamber.

Title: Apparatus for superimposing one article upon another
IPC: B65G47/88
Filed: 1974-03-21
Abstract: 1508124 Feeding articles to conveyers; stoppering METAL BOX Ltd 18 March 1975 [21 March 1974] 12556/74 Headings B8U and B8T Articles such as paint can lids are individually fed to a feed member 18 from which they are individually dispensed on to the tops of cans passing on a horizontal conveyer (not shown) located under the member 18, the latter comprising a slide member 16 down which a lid slides to be initially held by a pair of retaining fingers 55 whose lower ends are closed by a respective retaining lug 28 of an associated release member 22 which is biased to the position shown, and when a can passes under the fingers 55 it abuts trip pins 41 of the release members 22 thereby causing release of the members 22 which, owing to the engagement of the pin 41 with the upper outer periphery of the can, are caused to pivot outwardly about respective spindles 23 so that the retaining lugs 28 are thus moved outwardly from the fingers 55 whereby a lid initially held thereby is free to slide under gravity down on to the top of the can. The release members 22 are each comprised of a slot 25 between arms 26, 27, an aperture 37 being provided in each of the arms which is aligned with an aperture (32) provided in a catch member 29 pivotally mounted at 30 on member 22, Fig. 3 (not shown), and a latching stud 38 extends outwardly from the associated finger 55 through the apertures (32), 37, a notch (40) on the upper side of the aperture 32 engaging the latching stud 38 thereby holding the member 22 against movement. When a can abuts the trip pins 41 it initially causes upward rotation of the catch members 29, sufficient to disengage them from the studs 38, and then the continued movement of the can causes the above said outward movement of the members 22, such movement being opposed by a weak tension spring 48, which causes the return of the members 22 to their initial position when the can has passed. In a modified apparatus, Figs. 4, 5 (not shown), the members (22) are each biased to their lid-retaining position by a respective compression spring (62), the members (22) being mounted on L-shaped channel members (56) whose positions are adjustable to provide for the dispensing of different sized lids.

Title: An improved method of controlling the water content of hydrocarbon fluids
IPC: C10G33/04
Filed: 1940-08-06
Abstract: 549,699. Dehydration of hydrocarbons. STANDARD OIL DEVELOPMENT CO. Aug. 6, 1940, No. 12634. Convention date, Oct. 4, 1939. Drawings to Specification. [Class 91] The water content of hydrocarbon fluids is reduced by treatment with a solid inorganic dehydrating agent having several degrees of hydration characterized in that the hydrocarbon is first treated at a relatively high temperature with the dehydrating agent in a relatively high degree of hydration whereby part of the water is removed and the partly dried hydrocarbon is then treated with the hydrating agent at one or more successively lower degrees of hydration and at successively lower temperatures, the final stage being carried out with the dehydrating agent in a form having a dissociation pressure lower than the partial vapour pressure exerted by the desired final water content in the hydrocarbon at the temperature of operation. The preferred dehydrating agent is calcium chloride, but sodium sulphate or sodium hydroxide may also be used. An apparatus is described in which the dehydration may be carried out in either two or three stages. The principle of the invention may also be applied when it is desired to add to a hydrocarbon fluid a limited and controlled amount of water. This is carried out by allowing the hydrocarbon to contact a less hydrated form of the agent at a lower temperature followed by contact with a more hydrated form at a higher temperature.
