Title: Process for the preservation of blood and serum samples
IPC: G01N33/96
Filed: 1969-07-11
Abstract: 1,235,577. Preservation of blood and serum samples. BOEHRINGER MANNHEIM G.m.b.H. 11 July, 1969 [15 July, 1968; 19 March, 1969], No. 34990/69. Heading B1X. A process for the preservation of blood and serum samples to be used subsequently for the determination of components present therein comprises applying a known amount of the sample, to be investigated to an absorbent carrier with ion-exchange properties and then drying the carrier. The sample is eluted from the carrier using for example 0.33N perchloric acid or 2:1 chloroform-methanol immediately before the determination is to be carried out. The carrier may be paper, compressed cellulose, hydrophilic synthetic resin or textile fabric; it may itself have ion-exchange properties or may have ion-exchange properties imparted to it by impregnation or by fixing to it organic or inorganic powders or granulates with ion-exchange properties. Examples relate to determination of glucose, using the hexokinase -G-6-PDH method (NADP, ATP, hexokinase, glucose-6- phosphate dehydrogenase) and the GOD-POD method (peroxidase, glucose oxidase, 2, 2- azino-di-(3-ethyl benzothiazolone-6-sulphonic acid); determination of triglyceride (NADH, ATP, phosphoenol pyruvate, lactate dehydrogenase, pyruvate kinase); determination of galactose (NAD, galactose dehydrogenase); determination of cholesterol (dimethyl - benzene sulphonic acid, acetic acid, acetic anhydride).

Title: Electromagnetic sound recording and reproducing apparatus
IPC: G11B5/48
Filed: 1937-12-24
Abstract: 498,272. Telegraphones. LORENZ AKT.-GES., C. Dec. 24, 1937, No. 35702. Convention date, Dec. 24, 1936. [Class 40 (ii)] Relates to telegraphones in which means are provided for enabling a record, which has been made on a magnetic carrier whilst passing from one spool to another, to be obliterated during rewinding and a fresh record made at the same time. According to the invention, an obliterating head, a recording head, and a reproducing head are provided in the apparatus, together with electrical or mechanical means for arranging them in the order stated, relatively to the advancing movement of the record carrier, during movement of the carrier in either direction. In the arrangement shown in the Figure, the record carrier S, which may be a steel tape or wire, is driven in either direction from one spool to the other by means of an endless fibre belt 9, itself driven by a pulley 8. The obliterating head 12, the recording head 13, and reproducing heads 14 are mounted on a common support which may be rotated so that whether the carrier S is travelling from left to right or vice versa, the advancing part of the carrier can pass first through the device 12. and then through 13 and 14. Thus, with either direction of travel, recording or both recording and reproduction can be effected at will. Alternatively, the support for the recording &c. heads may be detachable, and reversibly attachable to the machine by plugs and jacks. In a further modification, an additional head or heads may be provided on the support, and selectively connected or disconnected as required according to the direction of movement of the tape or wire, by means of electrical switches. The driving arrangement shown has the advantage of preventing irregularities in the pull of the take-up spool from affecting the sound reproduction.
