Title: Improvements in or relating to animal cell cultures
Inventor: TELLING RONALD CHARLES
IPC: C12M1/36
Filed: 1963-10-30
Abstract: In the propagation of animal cells, in which the cells are suspended in an aqueous culture medium containing or being supplied with nutrients or additives known to be necessary or useful for the sustenance or multiplication of cells, the pH of the medium is kept between 7.3 and 7.8.  For the control of the pH, the medium is contacted with a non-poisonous gas (e.g. by flowing the gas across the top of the medium) which contains carbon dioxide at a partial pressure higher than the equilibrium pressure corresponding to the carbon dioxide content of the medium should the pH of the medium rise above a desired or defined maximum pH, and a non-poisonous gas which contains carbon dioxide at a partial pressure below the above-mentioned equilibrium pressure is sparged through the medium should the pH of the medium fall below a desired or defined minimum pH.  Alternatively, there is sparged through the medium a non-poisonous gas containing an adjusted amount of carbon dioxide for the regulation of the pH. The gas may consist of air, air diluted with an inert gas, or a mixture of non-poisonous gases preferably containing some oxygen. Non-poisonous anti-foam agents may be added to the medium to avoid frothing.  Examples are directed to the propagation of cloned baby hamster kidney cells and to growing strains of foot-and-mouth disease viruses in the cells for the production of vaccine.ALSO:Strains of foot-and-mouth disease viruses are grown in cloned baby hamster kidney cells propagated in suspended culture in an aqueous culture medium regulated to a pH within the range 7.3 and 7.8.  The virus particles are inactivated by a treatment with formaldehyde or acetyl-ethyliminine.  Aluminium hydroxide is

Abstract: 1449854 Stabilized ethyl cellulose DOW CHEMICAL CO 14 Sept 1973 [14 Sept 1972 23 July 1973] 43319/73 Heading C3F The tendency of ethyl cellulose lacquers to discolour in the presence of iron and moisture is prevented by the addition of one or more Na, K, Mn or Ca nitrobenzoate salts (except sodium m-nitrobenzoate). Sodium o- and p-nitrobenzoates are the most effective. In the examples the ethyl cellulose used has a D.S. of 2À30 and 5% viscosity of 70 c.p.s. The composition must have an apparent pH (as herein defined) of at least 5À7. The composition presumably inhibits to corrosion of the iron which gives rise to the discoloration of the lacquer.

Abstract: 440,475. Sights for aircraft guns. PILAIN, R., 20, Rue Terme, Lyons, France. March 22, 1934, No. 25812 /35. Divided out of and addition to 438,956 under which a Specification was laid open to inspection under Sect. 91 of the Acts, Sept. 24, 1934. [Classes 92 (i) and 92 (ii)] Relates to sights 125, Fig. 6, for aircraft gun mountings of the " ring " type which are automatically corrected for " own speed," as described in the parent Specification, when the gun 9 is moved in azimuth by rotation of the ring 38 and in elevation by raising the U-shaped elevating-arm 2. In the parent invention, " own-speed " is represented by an adjustable crank 96, mounted at the upper end of the elevating-arm, the crank being maintained parallel to the direction of flight by a primary gear contained within one limb of the arm 2 and the plane of movement of the crank arm being maintained parallel to the plane of the turret by a secondary gear contained within the other limb of the arm 2. According to the present invention, the primary gear is constituted by a chain-and-sprocket gear, Fig. 4, actuated by a rack 40<a> on the stationary ring of the turret and driving a worm wheel 77, Fig. 3, carrying a universal joint 96a representing the adjustable crank-pin 96, and the secondary gear comprises a train of parallelmotion linkages, Fig. 5, connecting a fixed arm 60 on the elevating axis to an arm 68 fast with the pivotally-mounted casing 72 of the worm wheel. The mounting of the worm-casing 72, crank-pin 96, sight supports 118, 119, and a pair of guns 9 at the upper ends of arms 69, 70, extending from the elevating arm 2 is shown in Fig. 6 and in the perspective view, Fig. 9. The guns 9, only one of which is shown in Fig. 9, are mounted in cradles 107 trainably pivoted at 105 in brackets 106 and crossconnected by a bar 110. The front sight support 118 is connected to the crank-pin 96 and the rear sight support 119 is adapted to slide in the rear end of a frame 116, the front end of which is universally jointed at 112 to a link 111 hinged on the bar 110. The centre part of the frame 116 is supported by a ring 117 connected by arms 115 and links 113 to the arms 69, 70. The arrangement is such that the axis of the frame 116 always remains parallel to the guns and to the side 80, 82 of the vector triangle. This triangle is completed by a short side 80, 81 representing the crank radius, and by the side 81, 82 which represents the resultant position taken up by the sight 125.

Title: Improvements in or relating to piezoelectric coupling elements
IPC: H03H9/54
Filed: 1961-12-12
Abstract: 1,010,764. Electromechanical couplings; transistor tuned amplifiers. SONUS CORPORATION. Dec. 12, 1961 [Dec. 12, 1960], No. 44438/61. Headings H3T and H3U. An electromechanical coupling for, e.g., an I.F. amplifier, comprises a pair 14, 16 of piezoelectric elements secured faceto-face with an electric conductor interposed between them. The elements may consist of axially-polarized ceramic discs carrying pairs of fired-on silver electrodes 20, 23 and 22, 24. As shown, the elements are secured to either side of a conductive foil 18 by a conductive cement, the foil being connected to a terminal common to the circuits of both elements. In a modification (Fig. 3, not shown), the foil 18 is replaced by silver wires embedded in the cement and touching both internal electrodes. In a further modification (Fig. 4, not shown), electrodes 23, 24 are separated from one another by insulating cement and have separate leads. This enables a balanced input circuit and an unbalanced output circuit to be used. The elements may vibrate in either a thickness or a radial mode and an improvement in bandwidth may be obtained by making the discs non-circular or of non-uniform thickness. An impedance match between the input element and the source may be obtained by varying the area of the input electrodes. The output impedance of the element 16 is made substantially greater than the load impedance R L . This is done by decreasing the capacitance between the electrodes e.g. by using a grid electrode or an annular electrode (as shown). In order to separate the radial and thickness mode resonances, the discs should have a diameter at least ten times their thickness. The I.F. amplifier of Fig. 5 uses a coupling 42 between a pair of transistor stages 48. Input and output matching circuits comprise further electromechanical couplings 38, 46.

A billet 19 is hydrostatically extruded using castor oil and the extrusion is stopped when the press is in operational equilibrium, i.e. constant extrusion speed. The reduced part of the billet is then examined to determine the relationship between the work-hardening and billet diameter between two points X, Y. These values are plotted, Fig. 3 (not shown), to give "a workhardening profile". The nose of a billet 30 to be extruded is then shaped by machining and swaging to produce the same work-hardening profile in the nose. The nose is examined after treatment and the amounts of machining and swaging adjusted to give the required result. The billet may be copper or aluminium. The shaping of the nose permits operational equilibrium to be quickly set up.
