Abstract: 801,872. Liquid dispensers; automatic feed weighers. D.K. MANUFACTURING CO. July 13, 1956 [July 18, 1955], No. 21703/56. Classes 116 and 143 A liquid dispenser comprises a closed tank 15 (Fig. 3), pivoted at 12 so that it normally adopts the chain line position, a continuously open spout 18, means for tilting the tank forwardly to effect discharge of liquid through the spout, a liquid supply conduit 20 connected to the bottom of the tank, and a valve 22 (Figs. 1 and 2 not shown) which is automatically opened to admit liquid to the tank through conduit 20 when a switch 32 is closed by forward tilting to the tank. The tank is provided with a heat insulating jacket 17 an electric heating element 24 and thermostat 26a. A receptacle, e.g. a coffee pot 41, is supported on one side of a beam 46, 54 fulcrumed at 48 and provided with a counter-weight 56 and a mercury switch 58 which, when the beam moves to the dotted position under the weight of a predetermined quantity of liquid in the pot 41, energizes a solenoid 70 which withdraws a spring latch 62 and allows the tank to pivot rearwardly so cutting off the feed of hot water to the pot. A handle 94 and linkage 80, 80a, 86, 88 effects tilting of the tank into its feeding .position where it is retained by latch 62. A manually operable switch 95 (Fig. 2 not shown) is provided to effect cut off before the beam moves if this is desired. In a modification (Fig. 5)' tank 102 is provided with a spout 110, a tilting handle 135, and an inlet valve 123 controlled by a switch 132, the weighing apparatus being dispensed with in this embodiment.

Patent GB-684571-A (GB)
Title: Cellulose esters
IPC: C08B3/16
Filed: 1950-09-07
Abstract: Cellulose esters of acyl-vanillic acids are produced by reaction between a cellulosic substance containing free hydroxyl groups and an "acyl-vanillic acid" (i.e. a compound in which the nuclear hydroxyl group of vanillic acid is acylated) in the presence of an esterification catalyst, an "esterification impeller" and a solvent for the ester formed.  An "esterification impeller" is defined as a carboxylic acid anhydride which causes the reaction of an acid with hydroxyl groups in cellulose or a cellulose derivative without itself combining with these hydroxyl groups.  Examples are halogen- and alkoxy-substituted aliphatic acid anhydrides, and especially monochloracetic acid anhydride.  Mixed cellulose esters of fatty acids containing up to 4 carbon atoms and of acyl-vanillic acids may be similarly prepared from a partial cellulose ester of the fatty acid.  Such esters may also be prepared by treating cellulose (preferably after an activating pretreatment with a lower fatty acid) with a mixture of a lower fatty acid anhydride and the anhydride of an acyl-vanillic acid in the presence of an esterification catalyst such as sulphuric acid and of an inert liquid diluent or a solvent for the ester formed.  In the example, cellulose acetate having 0.65 hydroxyl group for each anhydro-glucose unit, acetyl-vanillic acid (produced from vanillic acid and acetic anhydride-see Group IV (b)), monochloracetic acid anhydride and magnesium perchlorate are heated in nitromethane solution at 50-60 DEG  C. for 8 hours.  The product is precipitated by addition of water, filtered, washed, extracted with ether, washed and dried.  The esters can be dissolved in acetone, acetone-ethyl alcohol mixtures, or dioxane and films or filaments may be produced from the solutions.  The esters may also be used in the preparation of moulding powders.ALSO:Acyl-vanillic acids, wherein the nuclear hydroxyl group of vanillic acid is acylated, and particularly wherein the acyl group is derived from a fatty acid containing up to 4 carbon atoms, are prepared by esterifying vanillic acid with the appropriate acid anhydride, preferably in the presence of an esterification catalyst such as zinc chloride.  In the example acetyl-vanillic acid is prepared by maintaining a mixture of 16.8 parts by weight of vanillic acid, 85 parts of acetic anhydride and 2 parts of zinc chloride at 25 DEG  C. for 0.5 hour, heating it for one hour on a steam bath, and pouring it into a large mass of crushed ice.  The mixture is allowed to stand for 16 hours and the precipitated acetyl-vanillic acid is filtered off.  An aqueous suspension of the precipitate is treated with sodium bicarbonate and the solution thus obtained is filtered.  The filtrate is acidified with dilute hydrochloric acid, whereupon crystalline acetyl-vanillic acid separates out.  The acyl-vanillic acids may be used for the preparation of cellulose esters (see Group IV (a)).

Title: Pumping plant

Filed: 1955-08-06
Abstract: 789,692. Centrifugal pumps. AKTIEBOLAGET FLYGTS PUMPAR, and ENGLESSON, S. Aug. 6, 1955, No. 22712/55. Class 110 (1). Plant for pumping sewage or the like from a basin comprises one or more individual pump units each consisting of a pump assembled with its motor and adapted to be freely moved into engagement with a guide when lowered into the basin so that the unit is guided with its outlet in engagement with the opening of a discharge tube where it is retained in releasable but fluid-tight relation directly, or indirectly by its own weight. Sewage is pumped from a basin 1, Fig. 1, by two motor-driven pumps 10. After removal of a cover-plate 18, each pump 10 can be lowered as by means of a chain 17, with rollers 8, 9 carried by a pump bracket 6 engaging both sides of the flanges of a T-beam 5 so as to guide the pump into the position shown, with the discharge flange 15 of the pump in engagement with an entry flange 16 at the bottom of a rising main 2. The motor leads 11 are connected to a junctionbox 12. A disc valve 20 closes the exit from the inoperative pump. Instead of being on opposite sides of the T-beam flanges, as shown, the rollers 8, 9 may all engage the inner surfaces of the flanges so that, in conjunction with the inclination of the flanges 15, 16, a wedging action is obtained between the flanges 15, 16. In the modification shown in Figs. 5 and 7, each pump 10 is guided by a pair of parallel rods or tubes 29 which are engaged by members 32 of a pump bracket 33. A hook 34 on the discharge flange 15 engages an inclined back surface on the entry flange 16 of the rising main 35 to wedge the flanges together. There is a separate rising main 35 for each pump, the two rising mains being connected together near the top of the basin 1, or outside the basin, to permit inspection of the junction and any valve members therein. In further modifications, the guiding means may be formed by wires or by the rising main itself. The pumps may rest directly on flanges of the rising main, which in this case extends downwardly through the bottom of the basin and extends upwardly outside the basin.
