Filed: 1942-09-09
Abstract: 559,965. Visible card indexes. FREIBERG, S. B. Sept. 9, 1942, No. 12736. [Class 146 (i)] In a visible card index, the record-cards are coupled together in a series by narrow connecting-strips or links having a tongue-and-slot engagement with the cards, so that each link has a hinge connection with each of two adjacent cards. The links 22, Fig. 1, may have undercut lugs 25, 30 on opposite edges, the lugs 25 engaging in slots 24, Fig. 2, in one recordcard 20, and the lugs 30 engaging in wider slots 29 in the next card. The width of the slots 29 permits the cards to slide to a limited extent on the lugs 30, so that the series of cards may either be extended in overlapping arrangement or compacted together in the form of a block. The hinge connections between the links and the cards permit the cards to be spaced apart, as shown in Fig. 4, and any card together with those in front of it to be turned through an angle of 180 degrees, in order to expose its rear face and the front face of the card below. The links may be formed with slots 65, Fig. 12, and lugs 66, so that they may be connected together in a continuous chain of zig-zag form, each link having slots 63 in its ends, from which a record-card 62, Fig. 13, can be suspended by means of lugs 64. Each of the links may consist of two parts 81, 82, Figs. 20 and 21, having oppositely directed lugs 85, 89 formed with slots 86. The two parts of a link are interlocked, and the lugs are pushed through slots 87, Fig. 19, in adjacent record-cards 83, 84, Fig. 23. The slots 87 have wavy portions 88, by which the cards are engaged with the slots 86, to prevent withdrawal of the lugs. The slots 24, 29, Fig. 2, may be formed in a narrow strip 50, Fig. 10, or in a carrier-card, to the face of which a record-card 52 may be attached by the engagement of lugs 53 with slots 51 in the carrier strip or card. The slots 51 are so formed that the record-card may turn about the lugs 53, which serve as trunnions. Each of the connecting links may be formed by an integral bent portion at the top edge of one record-card, which has a tongue-andslot engagement with an adjacent card.

Title: Improvements relating to Syringes for Medical Purposes.
Inventor: LARCHE JEAN ETIENNE
IPC: A61M5/31
Filed: 1918-08-06
Abstract: 123,520. LarchÚ, E. J. Feb. 22, 1918, [Convention date]. Syringes; air injectors; cannulas. - The needle 9 of a syringe for intravenous injection or for tapping the pleura or for making an artificial pneumothorax, is surrounded by an adjustable guard 10 with a blunt end. When the needle has been inserted into a vein or the like, the guard is released by operating the fixing screw 14 and is moved to the limit of the groove 15 before being re-fixed, thus masking the point. The guard can then be pushed for a considerable distance into the vein without risk of puncturing the walls. Fluid is usually administered or withdrawn through the needle, but if the latter becomes clogged it can be withdrawn leaving the guard in position for the completion of the operation. To enable this to be done, the nozzle of the syringe is made to fit the socket 11 at the end of the needle and also the socket 13 at the end of the guard. The Specification also describes and illustrates a syringe with a permeable piston.

Title: Improvements in or relating to synthetic resins and their production
IPC: C08G63/06
Filed: 1935-04-30
Abstract: Synthetic resins are prepared by condensing an alkyl or aralkyl ester of an aromatic hydroxycarboxylic acid, or a mixture thereof with a phenol, with an aromatic dicarboxylic acid halide.  The reactants are preferably heated until the evolution of hydrogen halide ceases and then further heated in vacuo at a higher temperature (200--300 DEG C.) to remove by-products and unreacted materials.  Copper or cuprous chloride may be present as catalyst.  An example is given of the condensation of 2 mols. of methyl salicylate with one mol. of phthalyl chloride to give a pale yellow hard resinous material.  The methyl ester may be replaced by the ethyl, butyl and benzyl esters, and p-hydroxy-benzoic acid may comprise the acid component; in addition, a part of the ester may be replaced by phenol or an alkylphenol, e.g. 1 mol. of methyl salicylate and 1 mol. of the phenol can be condensed with 1 mol. of phthalyl chloride.  In conjunction with cellulose derivatives, such as the nitrate and acetate, the products are useful for the production of coating compositions, of which two examples are given containing (1) the resin, nitrocellulose, toluene, butyl acetate, zinc oxide and titanium oxide; (2) the resin, a castor oil-modified alkyd resin, nitrocellulose, dibutyl phthalate, butyl acetate, toluene and ethyl acetate.

Filed: 1944-07-08
Abstract: 580,505. Photographic materials. DIMSDALE, W. H. July 8, 1944, No. 13074. Drawings to Specification. [Class 98 (ii)] In coating both sides of a water permeable support such as paper with light sensitive colloid layer, one side is first coated with the lightsensitive aqueous coating composition, a layer of a water-insoluble alkali soluble resin is applied as an outer layer and allowed to dry, and then the other side is coated with the light sensitive composition. The resin layer is unaffected by the second operation of coating with light sensitive material and prevents the first coating from damage as it passes through the coating machine. The resin layer may be removed in alkaline baths. Although, if it is colourless and transparent, it may be left on the material, dissolving later in the developing baths. Suitable resins are natural resins, semi-synthetic resins, e.g. silvestic acid, the alkali soluble fraction of Yellow Gum Accroides, and synthetic resins such as alkyd resins and alkyl methacrylate polymers containing free carboxyl groups. The resins may be applied as solutions in ethyl alcohol, ethyl acetate or acetone. The product may be used for printing from wet negatives, a second layer of resin being applied, if necessary, on the other side of the support. The light sensitive layers may be supercoated with plain gelatin layers before applying the resin, and the support or other independent layers may be opaque or contain yellow dye or pigment for preventing the passage of light therethrough. The use of gelatino-silver halide emulsions is preferred but the light sensitive material may be a bichromate or a diazo compound and other colloids, e.g. agar-agar, alginates, vinyl acetates, vinyl acetals, far-hydrolysed cellulose acetates and water-permeable methyl methacrylate resins may be used instead of gelatin.

Title: Method of obtaining sodium salts of barbituric and thiobarbituric acid derivatives
IPC: A61K31/16
Filed: 1956-05-01
Abstract: Dry sodium salts of barbituric or thiobarbituric acid derivatives are prepared in sealed ampoules by removing the solvent from a filtered alcoholic solution of the salt at a temperature of between 30 DEG and 50 DEG  C. under a progressively reduced pressure, the solution being allowed to boil only when it has a consistency sufficient to prevent the "bumping" associated with boiling, the solution becoming a foam during the boiling.  The ranges of pressure for the stages of the process before and after boiling commences are 140-150 mm. of Hg and 20-10 mm. of Hg.  The sodium salts are obtained by dissolving the barbituric or thiobarbituric acid derivatives in sodium alcoholate, the solution containing an excess of sodium not exceeding 2 per cent of the theoretical amount required for the formation of the sodium salts.
