Patent GB-627781-A (GB)
Title: Improvements in or relating to electric motor control systems
IPC: H02P9/08
Filed: 1947-04-28
Abstract: 627,781. Transmitting mechanical power. GENERAL ELECTRIC CO., Ltd., CROFT, E. H., and RANDALL, H. April 28, 1947, No. 11321. [Class 38 (iv)] [Also in Group XXXVII] In a.system comprising a motor fed by an engine-driven generator, the motor and generator have separately excited windings both controlled by a servo system in accordance with changes in load of the engine, the arrangement being such that for heavy loads, e.g. when starting in the case of a traction system full resistance is in the generator field circuit and none in the motor field circuit, the generator field subsequently being strengthened and the motor field weakened. As shown, the sliders 28, 29 of resistances 5, 10 in circuit with the battery fed windings 3, 9 of the generator 2 and motor 7 respectively are operated by the piston 13 of a servomotor 12. The position of the piston 13 is determined by a two-way control valve 15 receiving oil by inlet 51 and actuated through a linkage 16 from the governor of the main prime mover 1, the coils 21, 22 of valves 17, 18 being energized by a master controller under normal conditions. In a modification, a separate servomotor is provided for each field resistance, but both are controlled by a single valve and interlocks ensure that the generator field is fully energized before the motor field is weakened. An overload device may be provided to ensure movement in the.load-reducing direction when the generator current exceeds a predetermined value.

Patent GB-456895-A (GB)
Title: Improvements in or relating to the quantitative and/or qualitative separation of materials in grains or pieces, such as minerals, coals and the like
IPC: B03B5/62
Filed: 1935-04-12
Abstract: 456,895. Separating solid materials. HOYOIS, L., 92, Chaussee de Ransart, Gilly, Belgium. April 12, 1935, No. 11403. [Class 82 (ii)] To separate a desired portion from a mass of granular material, e.g. minerals, coal, &c., a moving bed of the material is formed from which a portion is allowed to separate, the quantity separating from the bed being determined by the provision of adjustable water currents by means of which a predetermined quantity of the separated material is carried away. The separation may be purely quantitative or may be partly qualitative, for example in cases in which stratification occurs in the moving bed of material. Upward or downward currents of water may be produced at the point of separation to assist the qualitative separation. In the form shown a bed of material is carried down a trough A by a stream of liquid introduced at C and a portion separates from the bed and passes through an opening D, the area of which is adjusted by a movable damper G. A weir F is preferably provided on the side of the opening D remote from the feed end of the trough. The separated portion passes into a box E, being preferably confined therein in the form of a hillock by partitions H I. The box E has an adjustable discharge opening O and two water inlets J, K controlled by cocks 1, 2 respectively. By controlling the amount of water introduced into the box any desired hydrostatic head may be produced on the outlet O, this hydrostatic head determining the rate of discharge through the outlet. When a desired hydrostatic head has been established, there can be produced, by varying the amount of water introduced at K relative to that introduced at J, any desired strength of current, varying from zero when the cock 2 is closed to a maximum when the cock 1 is closed, passing from the inlet K to the opening O. This current which is preferably canalized by partitions S and T carries a portion of the separated material to discharge and thereby controls the amount separating from the bed in the trough A. If the hydrostatic head produced is such that it extends to the top of the weir F any desired upward current can be produced in the opening D by increasing the amount of water introduced at K. A downward current through the opening D can be produced by temporarily throttling down either or both of the cocks 1 and 2 to reduce the hydrostatic head.

Abstract: 928,257. Polyolefin coated sheeting. KALLE A.G. March 26, 1962 [March 28, 1961], No. 11504/62. Class 140. A polyolefin coated sheeting is produced by extruding a polyolefin upon a sheeting surface to which an oxidizing agent for the polyolefin has been previously applied. The sheeting, e.g. foils of regenerated cellulose, aluminium or paper, may also have an anchoring agent, e.g. melamine - formaldehyde resin, polyalkylene 'mine, alkyl titanates, and bivalent or multivalent diisocyanates, applied thereto. The anchoring agent and the oxidizing agent may be applied as a mixture or separately, the order being immaterial. The oxidizing agent, e.g. chromic acid, chromates, chlorates, persulphates, perborates, nitrates, nitrites, sodium peroxide, hydrogen peroxide and organic peroxides such as cumyl hydroperoxide, cyclohexanone peroxide, methyl ethyl ketone peroxide and benzoyl peroxide, may be applied in aqueous or organic solution or dispersion, the coated sheeting being dried prior to passage through a pair of squeeze rollers where it is combined in known manner with the extruded polyolefin film. The polyolefin e.g. polymers and copolymers of ethylene or propylene, may contact the sheeting surface at a distance of less than 5 cm. from the orifice of the slot die through which it is extruded. The surface may be partially covered with other layers, e.g. an image in printing ink, prior to coating with polyolefin. The surface not provided with the polyolefin layer may be coated with, for example, a moistureproofing lacquer.

Title: Improvements in aircraft pressure cabins
Inventor: WILLIAMS DAVID
IPC: B64C1/06
Filed: 1955-04-21
Abstract: 830,072. Aircraft pressure cabins. NATIONAL RESEARCH DEVELOPMENT CORPORATION. April 20, 1956 [April 21, 1955], No. 11506/55. Class 4. An aircraft pressure cabin has transverse hoops resisting hoop stresses and sufficiently closely spaced to take so high a proportion of the hoop stress borne by the skin and hoops that at the designed operating pressure differential the hoop stress in the skin is below the critical value at which a crack in the skin will propagate catastrophically. Failure of the cabin arising from rapid spreading of a crack due to fatigue or accident is thus prevented. In Fig. 2, the Z-shaped hoops 2 are thickened at 5 and the skin is also reinforced by hoops 4. Similar hoops may be disposed on the external surface of the skin, adjacent and between the frames 2, which then need not be thickened. A further form of hoop is shown in Fig. 5, comprising bands 4c secured to flanges on U-shaped frames 2c. Stringers 6 are provided. Preferably half, or at least half, of the material available for the skin and hoops is used for the hoops, and the radial expansion of the skin between the hoops due to the pressure differential nowhere exceeds by more than 5% the radial expansion of the skin in contact with the hoops.

Abstract: 290,219. Rouzet, L. May 10, 1927, [Convention date]. Condensers with plates on a rotatable spindle. A, Fig. 2, interleaving fixed plates are controlled by a cam C engaging a roller G on a crank M on the spindle A, a rotation of 360‹ of the cam and its operating knob producing a rotation of 180‹ of the spindle A. The cam may be such that the angle of the rotation of the knob is proportional to the increase in the wavelength or fre,- quency, or that a logarithmic wavelength scale is obtained, the condenser having semi-circular plates. The cam is constructed by milling with a tool of the diameter of the roller G, a crank corresponding to the crank M and a plate from which the cam C is made being carried by spindles corresponding to spindles A, B. When the cam is such that the ratio of the wavelengths is the same for all settings of the operating shaft B at equal angular distances, a scale divided logarithmically as in Fig. 5 is adjusted so that, the correct wavelength being indicated at one setting for a known wavelength, it will then indicate wavelengths correctly at all points. When the condenser is used with an inductance having a number of different values, marks are made corresponding to the correct position of the scale for each. The Specification as open to inspection under Sect. 91 (3) (a), comprises also a modified cam, Fig. 2 (Cancelled), and modifications in which a cylindrical cam rotates in a plane perpendicular to the moving plates, or in which the moving plates travel in a straight line instead of rotating.
