IPC: C12R1/045
Filed: 1991-01-02
Abstract: A method for selecting amino acid residues is disclosed which upon replacement will give rise to an enzyme with an altered pH optimum. The method is specific for metalloenzymes which are inactivated at low pH due to the dissociation of the metal ions. The method is based on altering the pKa of the metal coordinating ligands or altering the Kass for the metal binding. New glucose isomerases with an altered pH optimum are provided according to this method. These altered properties enable starch degradation to be performed at lower pH values.

Filed: 1993-03-25
Abstract: The invention concerns a method for limitation of the coating width and/or for prevention of damage to the roll ends in coating or surface-sizing of paper or of an equivalent web material. In the method, the coating agent, such as size, coating paste or equivalent, is introduced into the coating device to an application zone defined by a coating member (10), by a moving base (1), by lateral seals (20), and by a front wall (15) and spread onto the moving base by means of the coating member (10) loaded against the moving base. Into the areas outside the coating width, substantially over the width defined by the lateral seals and the roll ends, liquid is sprayed onto the moving base (1), in its running direction, immediately before the coating member (10) or directly into the nip between the moving base (1) and the coating member (10). The liquid jets are supposed to lubricate said nip and to dilute the coating agent that has entered into the areas outside the coating width. The excess amount of the sprayed liquid is collected off to prevent its entering into the recirculation of the coating agent, so as to prevent the coating agent from being diluted. The invention also concerns a corresponding equipment. <IMAGE>

Title: The vortex rocket reactor
IPC: G21D5/02
Filed: 1965-01-11
Abstract: 1,036,981. Rocket propulsion. UNITED STATES ATOMIC ENERGY COMMISSION. Jan. 11, 1965 [Feb. 18, 1964], No. 1108/65. Heading F1J. [Also in Division G6] In a rocket propulsion engine, hydrogen gas is isothermally heated by a nuclear reactor and exhausted through a divergent nozzle. The reactor is annular and encloses a central cylindrical chamber in which the hydrogen is heated prior to ejection through the nozzle. Adiabatic injection of the hydrogen into the chamber is through nozzles which are perpendicular to the chamber axis and tangential to the periphery but which impart a velocity greater than sound to the gas. The gas is concentrated round the chamber walls, is heated, by radiation from the surrounding reactor bars and is thus expanded at constant pressure isothermally. Expansion occurs radially inwards and the rotational kinetic energy is raised as the radius of the rotating gas bars falls. The reactor is formed of uranium impregnated beryllium oxide tubes confined within a cylindrical steel pressure vessel. An annular graphite reflector surrounds the pressure vessel and is cooled by the hydrogen passing through it prior to passage through the reactor. Boran control rods are mounted in the uranium bars. The thermal opacity of the hydrogen is increased by added carbon particles or halogens.

If the depressions 21 are parallel channels (Fig. 4, not shown), rather than a continuous sea surrounding an orthogonal array of islands 20 (Fig. 3, not shown), strip colour filters may be associated with them on the tube faceplate to provide a colour camera tube. The undulating form of the substrate may alternatively be produced by etching a fibre optic array of which the cores and the cladding exhibit different etching characteristics, or by mechanically impressing a pattern upon a heated substrate of glass.

Abstract: Preparations of the total suprarenal capsule or of the cortex thereof are treated with ammonia in the cold to precipitate the greater part of the 1-(3 : 4-dihydroxy-phenyl)-2-methyl-amino-ethanol-1, and are then subjected to treatment with formaldehyde, as described in the parent Specification, to inactivate the remainder of that compound, leaving the hormone of the suprarenal cortex unchanged. According to examples: (1) fresh suprarenal capsules are ground with water containing ammonia, and the solution is filtered, neutralized, concentrated, and then treated according to the process described in the parent Specification; (2) a suprarenal extract is concentrated in an atmosphere of CO2, concentrated ammonia solution is added to precipitate the 1-(3 : 4-dihydroxy-phenyl)-2-methylamino-ethanol-1, and the filtered solution is then treated with formaldehyde.  The quantity of ammonia employed may be reduced by first neutralizing the extracts with caustic soda and then adding a little ammonia, or by first adding a small quantity of ammonia or an ammonium salt such as the chloride, and then adding caustic soda.

Title: An improved method and apparatus for quench hardening
IPC: C21D9/32
Filed: 1959-01-14
Abstract: 897,809. Press quenching. GLEASON WORKS. Jan. 14, 1959 [Jan. 24, 1958], No. 1394/59. Class 72. A method of quench hardening a ring gear or like part comprises applying quenching medium to the heated part while it is held between clamping dies, the clamping pressure exerted on the part by the dies being periodically released as the part is cooled. As shown, a quench press comprises a press frame 26 slidable on rods 22 and 23. Rotation of cranks 35 through 180 degrees lowers die carrier 39 on to a workpiece such as ring gear G which is supported on lower dies on press frame 26. Similar rotation of cranks 28 lowers press frame 26 to carry the workpiece below the level of the quenching liquid. Die carrier 39 comprises a central cylinder 42 and piston 43 which actuate centering device 46, six cylinders 48 arranged in a circle around cylinder 43 with pistons 49 connected to an annular die member 52 which is adapted to bear on the inner portion of the upper face of the workpiece, and six concentric cylinders 59 with pistons 58 connected to annular die member 54. The reaction of the thrust applied to the workpiece is transmitted by screw 41 to tongues 67 which are locked below corresponding tongues 73 by the movement of lock bar 72. The lower die (Fig. 8) comprises concentric outer and inner annular members 87 and 88 which support radially disposed bars 89 on which rests the workpiece, member 87 being fixed at 88 and movable up and down by piston rod 94 attached to piston sections 96 and 97 by threads 95 of opposite hand, rotation of rod 104 with respect to these sections varying their spacing and hence the maximum length of the piston stroke. Alternate application of hydraulic pressure through passage 109 to cylinder 98 and through ports 62 to cylinders 48 rocks bars 89 about fulcrum 87 and flexes the workpiece 20-120 times per minute to the extent of 20-40 thousandths of an inch prior to quenching, the number of flexures being automatically controlled. The position of annular member 88 and assembly 96 is fixed when quenching by a stop means comprising a ring 112 rotatable around part 93 and having inclined surfaces engaging complementary inclined surfaces on another ring secured to part 93 so that rotation of ring 112 by piston 116 as far as it is allowed by preset eccentric 125 determines the angle of bars 89 when quenching. When the frame is lowered into the quench tank coolant is circulated by a pump through pipes 132 into chamber 135 through openings 136, groove 139, some flowing under the workpiece between bars 89 and out through passages 144 to the quench tank, while the remainder flows over the teeth of the workpiece to chamber 146 and returns to the quenching tank through openings 147. While quenching, the high pressures exerted by die members 52 and 54 and centering device 46 are released at a rate of 20-200 pulses per minute for 10-15 seconds in the case of automobile gear rings. The hydraulic and electrical circuits are described. Specification 806,993 is referred to.
