Abstract: 961,858. Stacking and nesting trays. W. H. LOCKWOOD. June 5, 1961 [June 13, 1960], No. 20143/61. Headings B8D and B8P. Open-top nestable trays with peripheral flanges have interengaging projections, e.g. 18 and recesses, e.g. 19 on the flanges so that when one tray is inverted and placed upon another a closed receptacle is formed, the bases of the trays having similar projections and recesses so that the receptacles so formed can be stacked. In one form, a square tray 12 has a peripheral flange 17, Fig. 1, with staggered projections 18 so arranged that when an identical tray is inverted and placed on the tray to form a closed receptacle 10, Fig. 5, the projections 18 on one tray engage in the spaces 19 on the other. The bottom surface of each tray has similar exterior projections 21 so that the closed receptacles so formed can be stacked one upon the other. The empty trays can be nested in the ordinary way since the sides slope outwardly. Fig. 9 shows a modification in which the projections are replaced by hook-like members 36, 40 and the engagement is effected by a relative horizontal twisting movement of the trays. When the hook members 36 are fully engaged, a rib 43c engages a depression 43d to retain the inverted tray in place. Triangularsection display trays 51, Fig. 20, can be formed into closed receptacles by snapping resilient hooks 64 over hook-receiving portions 65 and engaging portions 63b, 63c on the sides. Hooklike members 60 on the tray bottoms are slid together to stack the closed receptacles. The trays may be moulded of plastics or made of metal, wire mesh or plywood.

Filed: 1943-01-22
Abstract: 569,660. Purifying liquids. AMERICAN CYANAMID CO., DURANT, W. W., and BLANN, W. A. Jan. 22, 1943, No. 1162. [Class 46] A liquid purification system comprising at least one bed C<1> of hydrogen activated cation active material and one A<1> of anion active material is provided with a further bed C<2> of hydrogen activated cation active material and a bed A<2> of buffered' anion active material which has been treated with a reagent to adjust the effluent fluid to a predetermined pH value, together with an element which is contacted by at least a portion of the effluent from the buffered bed and responds to the presence in it of ionic materials so as to provide an indication of the condition of the effluent, or to control its flow, or both The buffered bed maintains the pH value of the effluent substantially constant during normal operation of system, but when one or more of the preceding beds' becomes exhausted the pH value of the effluent undegoes a marked change which causes the responsive element to operate the indicator or shut off the flow of fluid through the system. The fluid flowing into the bed C<2> should have a low content of ionizable anions and cations, for example, less than 20 parts in a million. The responsive element in the test cell may comprise a glass and a reference electrode actuating a pH meter, or a pair of electrodes connected to means for measuring the resistance between them. Alternatively, an indicator may be added to the effluent which, when it changes colour, causes a photoelectric cell, on which a light beam passing through the effluent falls, to operate an indicator or control mechanisms. The control mechanism may comprise a valve operated through relays and a solenoid to shut off the flow of fluid, together, if desired, with other valves which supply regenerating solution and washing fluid to one or more of the beds of ion active material.

Title: Low-molecular weight sulphuric acid esters of levans and process for preparing them
IPC: C08B37/00
Filed: 1965-01-11
Abstract: A polysulphuric acid ester of a levan, having a viscosity of (N)=0.03-0.07 (aqueous 83% solution at 22.5 DEG  C.), a sulphur content of 16-18.5% and a heparin action of 3-15%, is made by reacting a high-molecular weight levan with chlorosulphonic acid, and hydrolytically degrading the esters obtained in an acid medium.  The esterification may be carried out in presence of a base, e.g. pyridine, and a solvent, e.g. formamide.  The hydrolysis may be effected by treating a salt of the ester with mineral acid to pH 2.5, for e.g. 10-100 minutes at 30-70 DEG  C., or by treating with cation exchange resin.  In an example, levan polysulphuric acid ester is precipitated as pyridinium salt, and converted to sodium salt prior to hydrolysis.  The hydrolysed esters are used as blood-coagulants in pharmaceutical preparations (Division A5-A6].ALSO:A pharmaceutical composition having blood anti-coagulant properties comprises a pharmaceutically active amount of a levan polysulphuric acid ester of viscosity [n]=0.03-0.07 (aqueous 3% solution, 22.5 DEG C), sulphur content 16-18.5% and heparin action 3-15% in admixture or conjunction with a carrier, e.g. water, lactose, glycerine or vegetable oils. The composition, in which the levan ester may be in the form of sodium salt, may be administered as aqueous injection solutions, ointments, capsules, dragees or tablets.

Title: Process for the manufacture of a mineral feed additive essentially consisting of dicalcium phosphate
IPC: A23K20/26
Filed: 1961-01-12
Abstract: A feed additive, essentially dicalcium phosphate, is produced by adding phosphoric acid of at least 70% w/w to pulverized dry limestone in an amount to give CaHPO4.2H2O, whereby if the acid concentration is in excess of 85% w/w the acid is diluted to 84 to 85% w/w and if the concentration is less than 84%, there is admixed with the limestone quicklime fines or sodium pyrophosphate-a chemical dehydrating agent, such that the required concentration is obtained, the limestone acid mixture being mixed during the addition of the acid, the product resulting being thereafter maintained at 30 DEG  to 80 DEG C. for 6-48 hrs.  The acid is preferably admixed within 5 minutes in for example a rotary disc mixer, employing limestone powder which contains preferably more than 50% of -60 microns grams. The aftertreatment at 30 DEG  to 80 DEG C. may be effected by passing air at 30 DEG  to 80 DEG C. over the powder placed in a container, which may be a rotating tube drier.  The final product is a non dusting powder from which particles of greater than 0,5 mm. are removed by sieving and these can either be used separately or comminuted and added to the bulk product.  Up to one-fifth by weight of the limestone powder can be replaced by the chemical equivalent of dolomite, or up to 5% over the theoretical P2O5 requirements of CaHPO4.2H2O of phosphoric acid may be employed or between 10 to 20% excess, over the equivalent of phosphoric acid, of limestone or dolomite may be used.  The product may also contain less than the theoretical amount of water and thus contain between 48-50% phosphorus pentoxide.  The examples relate to the production of monocalcium phosphate using 84,5% concentration of acid, using 76% acid with quicklime as dehydrating agent, 80% acid with pyrophosphate as dehydrating agent and limestone with added dolomite, using a rotary disc mixer and rotary tube drier.
