IPC: C10M169/00
Filed: 1958-10-21
Abstract: A lubricating composition, suitable for use in internal combustion engines, comprises lubricating oil, 2.5-8.0 weight per cent of the calcium, barium, strontium or magnesium salts of both a C1-C5 and a C7-C12 carboxylic acid in proportions corresponding to 2.5-20 mols. of the salt of the C1-C5 acid per mol of the salt of the C7-C12 acid, and 1-5 weight per cent of a C16-C36 tertiary alkyl primary amine. The C1-C5 acid may be acetic, propionic, acrylic or lactic acid, while the C7-C12 acid may be capric, caprylic, nonanoic or lauric acid.  The mixture of salts may be prepared by coneutralization of the mixed acids with the metal oxide or hydroxide in the lubricating oil.  If desired, the neutralized product may be heated to 430-600 DEG  F. so that the mixed salts form a complex.  The amine may have the formula RC(R1)(R11)NH2, wherein R,R1 and R11 are straight or branched chain alkyl radicals of 1-18 carbon atoms such that the total number of carbon atoms in the molecule is 16-36.  The lubricating oil may be mineral or synthetic. Examples of synthetic oils are di-(2-ethyl hexyl) sebacate, polyglycols and their esters, complex esters, formals, silicones and carbonates.  The composition may also contain zinc di-(C3-C6 alkyl) dithiophosphates or alkoxy- or aroxy-polyalkyleneoxy mono- or di-esters of phosphoric acid as inhibitors of lead corrosion.  Additional ingredients which may be present in the composition are detergents (e.g. calcium petroleum sulphonate), viscosity index improvers (e.g. polyisobutylene), corrosion inhibitors (e.g. sorbitan monooleate), pour depressants, dyes and other grease thickeners.  In an example, a lubricating composition is prepared from (1) acetic acid, (2) "Wecoline AAC Acid" (a commercial mixture of caprylic, capric and lauric acids), (3) hydrated lime, (4) "Primane JM-2" (a commercial mixture of C18-C24 tertiary alkyl primary amines), (5) phenyl alpha naphthylamine, (6) a solution of the mono- and di-esters of phosphoric acid with the mono-n-butyl ether of polypropylene glycol dissolved in the unphosphated ether, and (7) mineral lubricating oil.  The effect of omitting (4), (5) and (6), and also of replacing (4) by P2S5-treated polybutene, P2S5-treated barium alkyl phenol sulphide or a blend of aluminium alcoholate and P2S5-treated polybutnene, is described.  The use of 3 - amino - 3,5,7,9,12 - pentamethyl - tridecane or 6 - amino - 2,2,4,4,6,8,8 - heptamethyl - nonane instead of (4) is also mentioned.

Title: Process for manufacturing tin-containing serum albumin particles suitable for binding technetium
IPC: A61K51/08
Filed: 1976-08-13
Abstract: Human serum albumin particles which are suitable for binding technetium are produced. Human serum albumin purified by dialysis is adjusted to a pH of 9.8 to 10.2 and kept at 71 to 73 DEG C for 10 to 20 minutes. It is then cooled to 45 to 50 DEG C, adjusted to a pH of 6.8 to 7.0 with acid and 0.17 to 0.22% by weight of tin(II) ions, based on the albumin, is added. The pH is adjusted to 5.2 to 4.8 by further addition of acid and a further 1.53 to 1.73% by weight of tin(II) ions, based on the albumin, are added. The temperature is raised to 71 to 73 DEG C and the suspension is subjected to countercurrent sedimentation with physiological saline solution. After decantation of the saline solution, the concentration of the particles is adjusted to 2.5 to 3.0 mg of albumin per millilitre of suspension with sterile distilled water. The suspension is then freeze-dried in vessels precooled to -80 DEG C. The freeze-dried human serum albumin particles can be labelled immediately before use with technetium-99m by adding isotonic sterile pertechnetate solution and shaking briefly.

In the motor of Fig. 2, the stator 2 includes a piezo-electric element 8 fixed to a wear-resistant lining 18 urged into contact with rotor 3 by a spring 13. Oscillation of the piezo-electric element is converted into rotation of the rotor. In a modification, Fig. 3 (not shown) the rotor includes the piezo-electric element and in a further modification, Fig. 4 (not shown) the rotor and stator both include a piezo-electric element. In yet another modification, Fig. 5, the motor includes several piezoelectric elements. The piezo-electric vibrators of the motors described may comprise several piezo-electric elements or layers connected electrically in series or parallel. The Specification discloses a large number of modifications including piezo-electric elements arranged to oscillate in one or in two modes, e.g. longitudinally, radially, in shear. Where the piezo-electric element is arranged to oscillate in two modes, one oscillation mode may be designed to urge the rotor and stator into contact and the other mode is then arranged to produce the rotary movement of the rotor. The motor may be reversible, Figs. 43, 44 (not shown). The motor may include several rotors, Fig. 42 (not shown). If the piezo-electric vibrator has two pairs of electrodes (one electrode may be common to the two pairs) then if one electrode pair is connected to a voltage source and the rotor is mechanically driven, then the second electrode pair can be connected to a load, the apparatus then functioning as a generator, Figs. 46 to 48 (all not shown).

Filed: 1964-08-19
Abstract: 1,014,708. Braiding-machines. MECAPRE S. A. Aug.19, 1964 [Aug.19, 1963], No. 33942/64. Heading D1C. A bobbin carrier for a braiding machine has a yarn tensioning device comprising a hook 19 slidable on a tube 11 against the action of a spring 20 coiled round the tube 11. The tensioning device is additional to the normal tensioning imposed by the spring loaded double hook 8 and bracket 7 controlling the pawl 5 and ratchet 4 mechanism for the bobbin spindle. The yarn from the bobbin 1 passes through a stationary guide 16 over hook 19 beneath hooks 8 and through guide 17. Alternatively the yarn passes over the stationary guide beneath one of the hooks 8 over hook 19 back round the other hook 8 and thence to guide 17. Any sudden variation in tension therefore causes the hook 19 to descend against the action of spring 20 thereby avoiding yarn breakage. The bracket 7 rises against the action of a spring contained in the tube 11.

Abstract: 741,713. Surface and outline gauges; gauging surface roughness. KOHAUT, A. Dec. 8, 1953, No. 34093/53. Class 106 (2). An apparatus for testing balls for roundness and/or surface defects, comprises two cylindrical rollers 1, 2 for supporting a ball 3 under test, means for causing the ball 3 to be rotated about two axes perpendicular to one another, and gauging means acting along an axis passing through the centre of the ball and perpendicular to the two axes of rotation. As shown, the rollers 1, 2 and an upper roller 4 all rotate in the same direction about their respective longitudinal axes to cause the ball 3 to rotate about an axis perpendicular to the paper. The roller 4 is also moved axially relative to the rollers 1 and 2 to cause the ball 3 to rotate about an axis a-a. Any vertical displacement of the roller 4 is a measure of deviation from the true form for the ball. By use of electronic measurement of the movements of the third cylindrical roller in the measuring direction, the components which originate from surface roughness may be separated by screening from those which arise from macrogeometric defects in shape.

Abstract: 1,140,959. Photographic flash apparatus. AGFA-GEVAERT A.G. Aug.1, 1966 [Aug. 6, 1965], No.34372/66. Heading G2A. A photographic flash apparatus comprises a rotatable socket for a flash-cube (as defined) and means for automatically ejecting the cube when all the lamps therein have been used. As shown, a flash-cube 3 having a base 3a with projections 3b is retained in a socket comprising an axially fixed, apertured wheel 2 by a hair-pin spring 4. As the cube is inserted it depresses an ejector 5 against the force of a spring 6 so that a lug 5c is pushed through a notch 1c in the apparatus housing 1 until it lies below an annular surface 1d of the housing; the cube and socket are then rotated through 45 degrees so that the ejector is prevented from returning and ejecting the cube by lug 5c engaging surface 1d; means for preventing rotation being made in the wrong direction e.g. a spring clip, are preferably provided. After each lamp is fired, the cube is rotated through 90 degrees to connect the next lamp into the firing circuit; this rotation may be effected manually, or automatically, e.g. by the film drive mechanism in a camera, by means of toothed or friction wheels 7 and 8, the former being connected by a shaft 9 connected to a grooved coupling disc 11 urged upwards by a spring 10 into driving engagement with projection 5c when a cube is present; when a cube is not present projection 5c lies in notch 1c and is not engaged. When the socket and cube have been rotated through one revolution, i.e. after all the flash-lamps have been used, projection 5c is aligned with notch 1c and hence ejector 5 is returned by spring 6 to eject the cube. An annular rubber disc may be provided over wheel 2 to prevent the cube being ejected violently.
