Abstract: 1388719 T-globulin and anti-serum therefor HADASSAN MEDICAL RELIEF ASSOCIATION Inc 1 Sept 1972 [2 Sept 1971] 40595/72 Heading A5B [Also in Division G1] The invention comprises pure T-globulin, i.e. a globulin fraction of M.W. 115,000-170,000 detectable in the blood of pregnant women and cancer sufferers, which when precipitated from serum and subjected to electrophoresis as below migrates towards the positive electrode at 5mm/hr. The electrophoresis is carried out in an agar block measuring 75mm (between the electrodes) x 25mm x 4mm, the current is 10mA, the voltage gradient is 4.5 volts/cm and the agar is buffered at pH 8.6. In preparing T-globulin, blood serum from cancer-sufferers and for pregnant women is treated with saturated ammonium sulphate to precipitate the globulin, from which the appropriate molecular weight fraction is collected as follows: (a) The globulin is dissolved in water (b) a precipitate is formed by addition of perchloric acid, (c) the precipitate is washed with neutral saline, (d) the precipitate is extracted with saline at pH 7.8-8.2 to dissolve out the T- globulin. T-globulin anti serum may be prepared by injecting T-globulin and Freund's complete adjuvant into a mammal. The antiserum may be purified by electrophoresis or by precipitation with perchloric acid followed by re-solution at pH 7.8-8.2. It may further be purified by treating it with normal blood serum to precipitate out all the anti-bodies except anti-T-globulin.

Title: Fluid pressure operable actuators
Inventor: THOMAS GORDON FREDERICK FRANK
IPC: B60T17/10
Filed: 1964-10-14
Abstract: 1,044,359. Fluid-pressure brakes. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. Sept. 8, 1965 [Oct. 14, 1964; July 28, 1965], Nos. 41884/64 and 32239/65. Heading F2F. In a compressed-air actuator 1 for vehicle brakes, particularly one having two diaphragms 3, 7, as shown, or alternatively (Fig. 1, not shown, of the drawings accompanying the second Provisional Specification) having a piston 10 and a diaphragm 4, so as to provide two working chambers (4, 6 in the former case, and 12, 11 in the latter embodiment), escape of air from the actuator in the event of rupturing of diaphragm 3, or of the piston seal 16, is prevented by a valve comprising a closure element formed or carried by the diaphragm or piston. In the embodiment shown, the diaphragm 3 carries a flexible valve closure element 14 of annular form which is integral with a central portion 15 attached by a screw 16 to the diaphragm, the element normally covering an inlet opening 5. The element 14 acts as a one-way valve when the diaphragms are in the brakes-off position to which they are biased by a spring 11, so that the brakes may be applied by admitting air either to inlet 5 or to another inlet (not shown) communicating with the chamber 6. Once diaphragm 3 has been moved away from inlet 5, by the admission of air to chamber 4, element 14 no longer covers the inlet, so that release of the brakes can be effected, while if chamber 6 is pressurized instead of chamber 4 the element 14 remains in the position covering the inlet to guard against rupture of diaphragm 3. In the modification of Fig. 2 (not shown), of the drawings accompanying the first Provisional Specification, the diaphragm 3 itself acts as the closure element, the opening 5 being provided in a sleeve 21 which has a series of peripheral holes communicating with the chamber 4, these being covered by a resilient ring to provide a one-way valve, necessary to enable air to pass initially into the chamber 4 on pressurizing the inlet. Referring to the drawings accompanying the second Provisional Specification (not shown), the valve in the embodiment of Fig. 1 is provided by a resilient ring 22 inserted in a groove either in an end face of the piston 10 or in the adjacent cylinder end wall opposite the end face of the piston (Fig. 3). The ring 22 may be of U-section and supported on a radial flange carried by the piston (Fig. 2). Alternatively, an annular valve closure element 28 (Fig. 4) of dished cross-section secured to the end wall of the piston may directly cover the inlet 14 to the working chamber 12 of the piston. The actuator in this case includes an alternative manual applying means 20 for operation by a cable and which has a lostmotion connection with a sleeve 19 secured to a member 18 of the clamping assembly 5, 6, 18 for diaphragm 4 which provides the second working chamber 11. The effective area of the first chamber 12 may be varied by attaching a sleeve 23 of appropriate thickness to the piston.

Title: Process and apparatus for stretching beaded edge films
IPC: B29C55/16
Filed: 1960-12-07
Abstract: 966,401. Film stretching apparatus. FARBENFABRIKEN BAYER A.G. Dec. 7, 1960 [Dec. 12, 1959], No. 42162/60. Heading B5B. An apparatus for simultaneously stretching beaded edge films longitudinally and transversely comprises pairs of inlet and outlet rollers 2 and 7 (Fig. 1), the inlet rollers being provided with rubber covering 2a (Fig. 2) to ensure that the beads of the film are not crushed. The marginal beads of the film 1 are engaged by two rows of gripping devices 3 (Figs. 1 to 3) which are mounted in slides or carriages 4 displaceable along rails 5 (Fig. 2) transversely to the direction of travel of the film. Fixed to the last gripping device is a knife 6 (Fig. 1) which severs the marginal bead from the stretched film. The marginal beads of the film are engaged by a wheel assembly 8, 9, 10 (Fig. 3) coupled by gear-wheels so that a predetermined speed can be imparted to the edge of the film at each gripper. Each gripper is mounted on springs 11 which can be adjusted by means of nuts 12. The tensile forces required to stretch the film transversely are transmitted by pressure cylinders 13 (Fig. 1) through rods 40 to the carriages or slides 4, the maximum displacement of the latter being limited by studs 14. The pressure in each cylinder is independently adjustable. The drive for the wheel sets of the gripping devices 3 is so subdivided into a number of groups that the speeds of the individual groups can be adjusted by means of variable speed gears 15 to 19 (Figs. 1 and 2) while stretching is in progress. The speed ratios within each group can be effected by changing the gear-wheels 21 to 23 (Fig. 1). The peripheral speed of the input rollers is determined by variable speed gear 15, gear-wheels 20 to 23 and chains and chain sprockets 24 and 25. The wheel assemblies such as 8 to 10 are driven by shafts 26 (Figs. 1 and 2) each being provided with a longitudinal groove and each carrying a bevel gear-wheel 27 axially displaceable along its shaft and meshing with a bevel gear 28 fixedly mounted on shaft 29 on the top of which is fixedly mounted the driving gear 10 of each wheel assembly. The output rollers 7 are driven by the adjustable variable speed gear 19 through a chain and sprockets 30 and 31. When it is desired to introduce a fresh film into the apparatus, the opposing carriages 4 with the grippers 3 can be moved towards one another to accommodate the initial width of the film and the wheel sets 8 to 10 can be moved apart by means of a lever 32 and a detent 33 (Fig. 3) whereby the marginal bead of the film can be introduced between the wheels 8 and 9 on the one hand and the wheel 10 on the other.
