Title: Improved process for producing insulin preparations with protracted effect
Inventor: HALLAS-MOLLER KNUD
IPC: A61K38/28
Filed: 1951-04-03
Abstract: Injectable insulin preparations with protracted effect, wherein pure insulin is used in a crystalline state, are obtained by producing an insulin crystal suspension exhibiting per litre a total content of one or more of the metals zinc, cobalt, nickel, cadmium, copper, manganese and iron above 7.5XAX10-3 millequivalent, where "A" indicates the number of international units of insulin per millilitre of the suspension.  Insulin crystals may be suspended in an aqueous medium containing one or more of the above metals in the form of a salt such as chloride, sulphate, nitrate or acetate, a hydroxide, oxide, metal complex or metal per se and having, or being adjusted to, a pH of 3 to 9, and preferably 7, provided substances suppressing the solubility of the crystals are not present.  The medium is preferably rendered isotonic with e.g. glucose, glycerin and sodium chloride.  The insulin crystals are preferably of at least 10m , especially 25 to 100m , in which case a stabilizer, e.g. a high molecular polysaccharide such as dextran should be present.  The pH is maintained by buffers such as an acetate, borate, diethylbarbiturate, phosphate, or maleate buffer or a mixture thereof.  Phosphate buffers are not suitable for zinc insulin crystals, but may be used for nickel insulin crystals. Preservatives such as phenol, methyl p-hydroxybenzoate, propyl p-hydroxybenzoate and phenyl mercuric acetate may be present.  The suspension medium may contain dissolved or precipitated amorphous insulin, or such may be provided by the added insulin crystals. Insulin crystals with increased content of one or more of the mentioned metals may be suspended in a medium such as water or fatty oils such as olive, sesame and peanut oil which does not per se show any content of the metals in question.  The suspension medium and the insulin crystals may be packed in separate ampoules.

Abstract: 592,705. Moulding hollow articles of thermoplastic material. WHEELING STAMPING CO. May 3, 1944, No. 8376. Convention date, March 20, 1943. [Class 87 (ii)] The head of a collapsable tube is formed by a combined injection and compression operation, and.then the tubular body is formed by a combined injection and extrusion operation. With the plunger 19 raised slightly above the position shown in Fig. 1, thermoplastic material is injected from a cylinder 7 through an orifice or orifices 4 into a chamber formed by a sleeve 2 and a mould 14. The plunger 19 then descends to the position shown in Fig. 1, compressing the material in the chamber and pushing the mould down. As the plunger 19 and mould 14 descend together, material injected from the cylinder 7 forms a tube on the plunger 19. When a shoulder 23 reaches the orifice(s) 4 it cuts off the stream issuing from the latter. The mould may descend faster than the plunger, as shown in Fig. 2, leaving the tube free to be blown off the plunger by air passing through a duct 25 in the latter. The heated upper portion 3 of the sleeve housing and the cooled lower portion 10 are separated by insulation 13a. In a modification, the mould 14 is screw-threaded to form an exterior thread on the tube, and as it parts from the plunger it pulls the tube off the latter, assisted perhaps by air from duct 25; the tube is then unscrewed from the mould.
