Abstract: 1,257,535. Centrifugal strainer. SOC. FIVES LILLE-CAIL. 8 Dec., 1969 [9 Dec., 1968], No. 59814/69. Heading B1D. A centrifugal strainer drum 10 has a hub 38 mounted for rotation on a pivot 34 which is rigidly secured to the upper half 22 of the enclosing housing, the upper half being resiliently supported relative to the fixed lower half of the housing by rubber blocks 26, or by a rubber ring (60) (Fig. 2, not shown), located on a level with the centre of gravity of the whole supported structure, including the drum, which is also the level of the geometric centre of gravity of the inner surface of the drum. This ensures that any vibration of the structure is limited to the horizontal direction. Fig. 1 shows a frusto-conical, solid drum, lined with screen 12, but the drum could be perforate and cylindrical. Material enters the drum from pipe 50 via rotating bladed wheel 52 and annular conduit 56. In an alternative construction (Fig. 3, not shown) pipe 50 carries an annular disc (62) making a very small clearance with the rotating part of the material inlet, thereby minimising the flow of air created through the drum by wheel 52. The upper and lower halves of the casing are sealed together by flexible ring 30 or bellows. The upper half may have a thick wall to increase its weight or carry additional weights.

Abstract: 1290733 Controlling inclination of vehicle lights; correspondence control systems JOSEPH LUCAS (INDUSTRIES) Ltd 12 Feb 1970 [24 Feb 1969] 9702/69 Headings G1A and G1N The inclination of the headlamps of a vehicle is adjusted to take account of changes in the attitude of the vehicle body. Movement at the front and rear of the vehicle is sensed by potentiometers which control the voltage applied to coils 18, 19 wound on bi-metallic strips 15, 16 respectively. Strips 15, 16 are connected by spring strip 14 and are arranged to flex inwards when heated. A plate 13 is attached to spring strip 14 so that it moves to a new position when the heating currents are different e.g. when one end of the vehicle is loaded so that its attitude changes. Photo-cells 23, 24 are connected to motor 27 through control unit 26 so that the motor rotates in opposite directions dependent on which photo-cell is illuminated. The headlamps are moved by strip 11 which is driven by motor 27 and has a mask 25. When plate 13 moves the light beam will influence one of the photo-cells 23, 24 to operate the motor in the correct direction and mask 25 will be moved until it again masks both photo-cells when the inclination of the headlamps will be correct for the particular attitude of the vehicle. The light source may be attached to plate 13 or, as shown, the light source may be fixed and the light beam pass through hole 22 in plate 13.

Abstract: 1313513 Transistor deflection current generator DECCA Ltd 1 May 1970 [9 June 1969] 29109/69 Heading H3T Deflection current for a cathode-ray tube deflection coil 10 is provided by a circuit comprising a feedback resistor 14 in series with the coil, a transistor 15 and a diode 16 connecting the coil to a first voltage source 17 and a switch 30 responsive to the voltage across the coil to connect the junction of the transistor and diode to a higher voltage source. So long as a steady current is required by the coil it is supplied by the low voltage source but when an increase is required in response to the input at 13 the resulting increase in voltage across the coil is fed through a capacitor 37 to the base of transistor 30 to connect the coil to the higher voltage source. Diode 25 prevents excessive voltage across the coil and diode 33 protects transistor 30 and provides a threshold such that small changes in coil current do not switch on transistor 30. Base bias may provide a further increase in threshold. Transistor 30 may be replaced by a complementary Darlington pair with a protecting diode connected to the first of the pair (Fig. 2, not shown). A second circuit 11, 19 &c. provides for push-pull deflection.
