Title: Method and apparatus for Treating Walls of an Enclosure
IPC: B08B3/12
Filed: 1967-03-15
Abstract: 1,186,442. Cleaning tanks. PYRATE SALES Inc. 15 March, 1967 [21 March, 1966], No. 12258/67. Heading A4F. [Also in Divisions B2 and F1] Spray apparatus for cleaning the interior of an oil tank comprises a pair of pneumatic spray nozzles 65 adapted to discharge the spray material as an aerosol in opposite directions and mounted so as to be rotated simultaneously about axes A and B which are substantially at right angles to each other. Each nozzle includes a resonator cavity 74 into which gas or steam is discharged in a supersonic jet stream from an orifice 76. The gas or steam is then directed into an annular well 77 and is emitted as sonic waves having a frequency greater than 10,000 cycles/sec. within a well defined angle of between 10 degrees and 50 degrees. The spray material is discharged into the sonic field through a central tube 67. The fluids reach the nozzles via generally co-axial conduits and part of the gas or steam is diverted so as to drive a pneumatic motor 80 which rotates a turret 10 via gears 114, 115 and a pinion 119 which engages a fixed gear 120 forming part of the stationary turret support 27. The nozzles are caused to rotate about the axis B by a gear 121 on the nozzle arm 11 which gear engages a fixed gear 122. The meshing gear teeth of gears 114, 115 and 121, 122 differ by a small number to achieve uniform spraying over the tank interior. The gas and steam conduit is provided with baffles and a filter and the position of the spray within the tank may be adjusted. The walls of the tank create an aerosol fog soon after spraying is started and the aerosol fog beam C is subsequently discharged through this fog. The fog may be produced initially using a solvent only for solids which are subsequently sprayed in solution cleaning liquids such as detergents, bond releasing agents, or alkalized or acid solutions may be used. Amine-amido sulphonates are stated to be particularly suitable.

Title: Improvements in gyroscopic stabilizer systems
IPC: G05D1/08
Filed: 1923-05-09
Abstract: 197,680. Metropolitan - Vickers Electrical Co., Ltd., (Assignees of Lamme, B. G.). May 15, 1922, [Convention date]. Systems for continuous-current motors only; regenerative systems.-In apparatus for preventing or controlling the rolling of vessels by imparting precessional motion to a stabilizing gyroscope, the precession is produced by an electric motor which is adapted to operate regeneratively to control the speed of precession. The gyroscope 3 comprises a rotor 6 mounted on a vertical axis in the casing 5 which is pivoted on trunnions 4 disposed transversely of the vessel and carries a gear wheel 9 meshing with a pinion 10 on the shaft of the motor 11. The generator system comprises a prime mover 14 driving an alternating current generator 15, a continuous current generator 16 and an exciter 17. The generator 15 supplies current to the squirrel-cage motor 8 on the shaft of the rotor 6 and the generator 16 supplies current to the rotor of the precession motor 11. The motor 11 has a shunt field-winding 13 connected to the exciter 17, and the generator 16 also has a shunt winding 20 connected to the exciter 17 through reversing switches 21, 22, a rheostat 24 being preferably included. The generator 16 may also have a relatively weak series winding 25 to assist the winding 20 during starting. The switches 21, 22 are controlled by an auxiliary gyroscope 34 which is responsive to rolling motions of the vessel, so that the direction of the current in the winding 20 changes with changes in the direction of roll. The prime mover 14 has a falling speedtorque characteristic so that, as the motor 11 accelerates, the speed of the prime mover tends to fall. As the motor 11 has a substantially constant field its speed is approximately proportional to the voltage of the generator 16 so that when a torque is applied tending to increase the speed beyond a certain maximum the motor acts regeneratively, and thus limits the velocity of precession of the gyroscope 3. Also reduction of the generator 15 is resisted by inertia of the rotor 6 which, through the rotor 8 acting regeneratively, returns power to the system during part of the cycle of operations. The motor 11 is provided with a brake 27, which is biassed towards operative position by a spring 29 but is adapted to be released by an electromagnet 30 connected to the exciter 17 through switches 32, 33 so that its circuit is completed when either of the switches 21, 22 is closed. When the winding 20 is de-energized the magnet 30 is also de-energized, but owing to delay in the dying-down of the magnetic flux the applications of the brake is delayed until the motor 11 lias been brought almost to a standstill.

Operating doors by weights and springs and by toothed-gear mechanism; indicating and signalling operation of doors.-The usual clutch device between the shaft e of the door-operating gear d, c and the worm f of the hand-gear m, p is under the control of a hand-lever q carrying a link r connected through a lever l and rod k with the movable clutch element h<1>, the lever q being normally maintained in a position with the clutch elements in gear by a cable t of a distant control u and a spring s. The clutch comprises the movable member h, h<1> the ratchet teeth of which engage the ratchet teeth on the member g. The member h is feathered to slide on the shaft e, and the member h<1> is feathered to slide on the member h, and between the members h, h<1> is a spring j. In the position shown, with the lever g in the mid-position, the clutch is in gear and the door can be opened or closed by the hand-gear. To allow the door to drop, the lever q is lifted by hand against the action of the spring, or the cable t is slackened by the movement of the distant control: in the latter case, the spring s pulls the lever q into a lowered position. Either movement of the lever q displaces the link r and swings the lever l to the right, opening the clutch elements. By lifting the lever q again to its midposition, the door can be opened by the hand-operated gear even when the distant control is set at the "clutch open" position. For doors sliding horizontally, closing weights or springs are provided. Alarms and signalling devices are used to indicate the position of the door or the movement of its release.

[Class 49] A whippable milk preparation is made by homogenizing fresh milk and incorporating with it either before, during or after homogenization a proteinaceous material, such as milk powder, which depresses the surface tension at the interface of the fat particles and the aqueous constituent of the milk, the amount of proteinaceous material added being not substantially greater than that which is required to raise the temperature at which the product will whip to the temperature corresponding to the upper limit of the rapid increase in that temperature for the material utilized. Whole and'or skim milk powder may be used in amounts between 1 and 5 per cent. by weight, and a small amount of protective colloid, e.g., one or more of the following materials : gelatin, agar-agar, albumin, globulin, sodium alginate, gum tragacanth and gum arabic, may be added to stabilize the preparation so that it will stand for 1-5 minutes after the whipping.
