Title: Radioimmunoassay for renin activity
IPC: G01N33/573
Filed: 1975-09-03
Abstract: 1509460 Determination of renin activity MALLINCKRODT Inc 3 Sept 1975 [6 Sept 1974] 36342/76 Heading G1B A radioimmunoassay method for the determination of the renin activity of a plasma sample by measurement of the rate of generation of angiotensin I from angiotensinogen comprises the steps of (a) if necessary, adding a known amount of angiotensinogen to the sample, (b) mixing the product with a buffer solution and an inhibitor or inhibitors for enzymes which convert angiotensin I to other substances, (c) incubating the mixture to generate angiotensin I, (d) mixing the product with a predetermined amount of radio-actively labelled angiotensin I, a predetermined amount of an antibody for angiotensin I and a buffer solution, (e) incubating at at least 12‹C, (f) separating bound from unbound angiotensin I, for example by use of a strip of ion-exchange resin membrane, (g) determining the relative proportion of bound and unbound labelled angiotensin I, and by determining the unlabelled angiotensin I content of the reaction mixture of (d) by comparison of the relative proportions of bound and unbound labelled angiotensin I determined in step (g) with the relative proportions of bound and unbound labelled angiotensin I in standard radioimmunossay reaction mixtures containing known amounts of unlabelled angiotensin I and (i) determining the renin activity of the unknown sample from the difference between the angiotensin I content of the mixture of (d) and the angiotensin content of a similar reaction mixture which has been kept at at most 37‹C to avoid significant conversion of angiotensinogen to angiotensin. The inhibitor used in step (b) may be 8-hydroxy quinoline and/ or 2, 3-dimercaptoethanol and the buffer may be potassium acid phthalate or 2, 2-dimethyl glutanic acid. The label used in step (d) is generally I-125 but may be J-131, and the buffer used for the assay (step (d)) may be tris-buffer containing human serum albumin and sodium azide.

Patent GB-763673-A (GB)
Title: Improvements in and relating to fluorocarbon acids and derivatives
IPC: C07C59/135
Filed: 1954-12-16
Abstract: The invention comprises normal perfluoro beta-alkoxypropionic acids having the formula F(CF2)nOCF2CF2COOH where n has an integer value of 1 to 8; and their acid halides, metal and ammonium salts, and alkyl esters.  The acid fluorides of these acids are prepared by electrolysing a solution of the corresponding hydrocarbon alkoxypropionyl fluorides or chlorides in anhydrous liquid hydrogen fluorides (see Group XXXVI).  These acid fluorides are insoluble in liquid hydrogen fluoride and are either evolved in admixture with hydrogen or settle at the bottom of the cell depending on their volatility.  The acid fluorides can be hydrolysed with aqueous alkali to form alkali metal salts of the acids which in turn can be treated with concentrated sulphuric acid to form the free acids.  The acids will readily react with metals, metal oxides, hydroxides and carbonates, or ammonium hydroxide in water or an inert reaction solvent to yield metal and ammonium salts, or with phosphorus pentachloride, benzoyl chloride or phthalyl dichloride to produce the corresponding acid chlorides which may in turn be reacted with bromine, iodine, calcium bromide or calcium iodide to form the corresponding acid bromide or iodides.  Specifications 686,678 and 763,674 are referred to.

Title: Analysis of emulsions and suspensions
IPC: G01N21/31
Filed: 1972-08-04
Abstract: 1438631 Photo-electric analysis of dispersions SIR HOWARD GRUBB PARSONS & CO Ltd 1 Aug 1973 [4 Aug 1972] 36547/72 Heading G 1A The amount of a disperse phase in a dispersion medium is analyzed by a double beam absorption spectrometer; one beam passes through a sample cell and the other through a cell containing only the dispersion medium. The latter cell has a variable path length which is used not only to achieve an initial balance between both paths before measuring commences, but also to balance the two paths during measuring at a wavelength not affected by the disperse phase. When the wavelength is changed to one which is affected by the disperse phase the resulting imbalance of absorption between the two paths is a measure of the amount of disperse phase present. Milk may be analyzed for lactose, protein, fat and water content using the spectrometer. Fig. 1 shows an infrared absorption spectrum for milk, .the small peaks at c, d, and e being due to fat, protein and lactose respectively, while the rest of the curve, including peak a, is due to water. The spectrometer is shown in Fig. 3, comprising source 1, variable attenuator 11, chopper 3, a plate 4 carrying the sample and reference cells 5 and 6, a filter wheel 8 and detector 10. The apparatus is initially balanced without the cells in the two paths by using the device 11. The two cells are then filled with water, this being the dispersion medium of milk, and the filter wheel is set to pass 4À8Á, this being the peak a in Fig. 1. The path length of cell 6 is adjusted until the absorption of the two paths is the same, the chopper 3 allowing the paths to be measured in sequence. Next milk is put in the sample cell in place of the water and the apparatus is balanced again, still at 4À8Á. The imbalance at 5À7Á, 6À43Á and 9À6Á is then measured to determine the amount of fat, protein and lactose. Finally water is put in the sample cell in place of the milk, and with the filter wheel positioned at 4À8Á again, the imbalance gives the total content of the dispersed phase (or by subtraction the water content). The adjustment of the path length at 4À8Á may be effected automatically by a motor controlled by the photo-detector output via a sample and hold circuit. The cell plate 4 may have a temperature stabilizing water flow, Fig. 6 (not shown), the sample fluid also being pre-heated by this flow before entering the sample cell.

Abstract: 917,159. Lathes; chucks. USINES TORNOS, FABRIQUE DE MACHINES MOUTIER S.A. Nov. 5, 1959 [Nov. 6, 1958], No. 37530/59. Class 83 (3). An automatic lathe comprises a sliding headstock 3 for feeding and rotating a stock bar 6, tools 17 arranged in front of a fixed or moving sleeve 20 through which the stock is fed, and guiding and pushing means for controlling the stock. The headstock 3 is carried on a slide 7 moved against a spring by a cam, on a shaft at the rear of the lathe, acting through a lever 8, a crank 9, carrying a pin 12, and a block 13. The pin 12 and block 13 are adjustable to vary the position and stroke of the headstock. The tools 17 are fed by levers 18 carrying adjusting screws. A support 5 carries additional tools, such as drills or taps, on a rocker arm or turret, the tools being indexed and fed by a cam on the cam-shaft. These tools may be non-rotary or may be rotated or counter-rotated relatively to the work. When a piece has been machined, it is parted off, released, and the headstock is then moved back to grip a new piece of stock. The stock-bars are carried in tubes of a turret 25, the uppermost tube carrying the operative bar. Each tube has a pusher 26, Fig. 5, that in the upper tube being continuously urged forwards by a pivoted arm 27b on an endless chain 28 moved by a continuouslyenergized motor 31. When a stock-bar has been used as far as possible, the chain returns the pusher and stock-end to the other end of its tube where the arm 27b is released by a ramp 96 and a projection 27a trips a lever 97 to enable a weight 33 on a cord 104 to index the turret. A spring-pressed rod 34, acting on a pawl lever, assists the motor 31 in controlling movements of the stock-bar. Thus, when the stockbar end should be removed and if the friction is too great to enable the motor 31 to withdraw it, in succeeding non-cutting cycles of the lathe, the rod repeatedly moves the stock back twice the distance it is moved forward until the end is free of the frictional holding points, such as the sleeve 20, and can be withdrawn easily by the motor. When all the stock has been used, the stock ends are removed from the turret and replaced by new bars. In a similar way to that described in Specification 917,158, the chuck jaws 71, Fig. 2, are closed by tubular abutting sections 44, 45, 46 moved axially by levers 47 actuated by a rocking lever 53 through a conical sleeve 49, The lever 53 is rocked to close or release the chuck by a cam-grooved lever 59 acted upon by projections 63, 66 on a cam 64 on the cam-shaft 65, the chuck being held by friction in either of its two positions. In a modification, the rod 34 actuates rack-andpinion gearing instead of a pawl lever.

[Class 40 (iv).] The diaphragm a, Fig. 1, of a subaqueous sound receiver is damped by rubber, leather, felt, &c. c carried by a plunger g, the stem b of which passes through a support e in the casing d and extends through the back f of the casing so as to be adjustable from the exterior. The exterior portion of the rod b may be separated from the water by a cap h. According to modifications the diaphragm is damped at its centre. This may be effected by arranging the device c to bear against the centre of the diaphragm, Fig. 2 (not shown), or by causing the plunger to engage about the edge of the member a<1> for converting the vibrations of the diaphragm into current fluctuations or against an intermediate member as shown in Figs. 3 and 4. If desired, a gaseous or liquid substance may be employed as the damping medium. Fig. 5 shows a construction employing air damping in which the plunger g carries a cylinder l having a small hole or passage n, the stem b carrying a plunger head m making an exact fit in the cylinder. Instead of a plunger, the cylinder may be closed by a diaphragm.
