Abstract: 1334612 Centrifugal filter FIVES LILLECAIL 19 April 1971 [17 March 1970] 24434/71 Heading BID  A centrifugal strainer separator comprises a cylindrical basket 10 mounted for rotation at the lower end of a driving shaft 12 which is suspended in pendular fashion on a supporting frame 14. The basket is connected to the driving shaft by a flexible coupling, e.g. a ball joint 13. or a universal joint, ensuring the rotation of the basket whilst permitting rocking movements of the rotor relatively to the shaft, a resilient restoring device, e.g. a resilient ring or series of studs 15, interposed between the basket and the shaft opposing these angular movements of the basket. The driving shaft itself may be flexibly connected 22 to the shaft of motor 23. The coupling between the driving shaft and the basket also suitably includes a damping device (Fig. 3, not shown) to brake the rocking movements of the basket relatively to the shaft and the precession movement of the shaft-basket assembly, e.g. in the form of discs (53) mounted transversely on the driving shaft so as to be capable of sliding on the shaft and taking up variable inclination relative to the axis of the shaft, the edge of the disc being clamped between two jaws (57) fast with the basket. A centering device may also be provided which makes it possible to keep the driving shaft and the basket coaxial thus suitably being in the form of a cone (43) (Fig. 3, not shown) which may be displaced upwards to bear against a corresponding conical recess (45) to prevent angular movement. Means may also be provided for preventing angular movemet of the driving shaft relative to the supporting frame (Fig. 4, not shown).

Title: Improvements in electrically actuated gongs and like sound producing apparatus
IPC: G10K1/064
Filed: 1920-08-25
Abstract: 150,350. Magerle, E. Feb. 24, 1919, [Convention date]. Bell-operating mechanism, electric.-Relates to electric bells and like sound-producing apparatus in which a hammer or tapper is actuated by a solenoid which co-acts with a resilient contact to make and break the circuit. The solenoid plunger 2, of magnetic material, is in electrical contact with a metal guiding sleeve 9 on which the solenoid coil 1 is wound, and rests on a resilient contact 7. On making the circuit, the current flows through contact 7, plunger 2, sleeve 9, and through the coil 1, thus attracting the plunger 2 up the coil and breaking the circuit at contact 7, the period elapsing before contact is broken, and consequently the quality of the stroke, depending on the nature of the contact spring 6. The hammer head 4, of non-magnetic material, for example wood, may be mounted on an adjustable rod 3, or may be spaced from the plunger by a spring, or it may have a rod 3, Fig. 6, which slides in a hollow plunger and is spaced therein by a spring 19 from a similarly sliding stud 16, which engages between two springy contact strips 21, 22. For slow beat bells a plunger shaped as at 2, Fig. 2. without the head 4 and rod 3, may function as the hammer. The striking appliance may all be located within the gong 8, or may be outside and strike on two gongs, the contact beneath the plunger being shown in this case as telescopic members pressed apart by a helical spring. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a bell push for causing a solenoid-operated bell to make two strokes only, the solenoid in this case not requiring a contact 7, and a flange being provided to prevent the plunger 2 falling down to touch the gong. The push is fitted with a rocker 32, Fig. 9 (Cancelled), through which the circuit is completed when first touched by a push spring 31, but when further pressure is applied to the push the circuit is broken by one rocker arm being raised off the contact plate 34. A similar sequence occurs when pressure is taken off the push; thus' two waves of current are sent through the solenoid, giving two strokes on the gong. This subjectmatter does not appear in the Specification as accepted.

Title: Engine-drive unit having a converter and speed variator
IPC: F16H47/06
Filed: 1971-04-19
Abstract: 1332552 Variable-speed friction gear; change-speed control; engine/transmission units AUTOMOBILES PEUGEOT and REGIE NATIONALE DES USINES RENAULT 19 April 1971 [1 April 1970] 24806/71 Heading F2D [Also in Division B7] In a transverse unitary automatic enginetorque converter-gear-box-differential assembly for a motor-vehicle in which the gear-box is of the continuously variable friction gear type having interpenetrating friction discs 5, 6 respectively fast with an engine driven shaft 4 and an output drum 7 which is carried at each end in journals of a rocking yoke 8 pivoted transversely at journals in a fixed casing 1 about the axis ZZ of an output layshaft 9 to effect ratio shift by hydraulically operated linear piston motors 15, 16 (Fig. 2) acting each side on abutment faces on the rocking yoke 8, as described in Specification 1,280,588, the engaging clamping pressure on the interpenetrating friction discs is hydraulically applied by a servo-motor 10, 11 supplied by hydraulic pressure from a pump 19 via a line 12 to the servo 11. The pressure is automatically regulated by engine manifold depression acting via a diaphragm and pipe 29-31 on a push rod 27, 28 of a valve 17 which via a plate 26 pivoted at 32, on a bell crank lever 33, adjustably moves a slide 23 controlling an orifice 24 to automatically regulate the pressure in the line 12 according to the engine load and hence the transmitted torque. The valve 17 further has a spring- loaded plunger 38 projecting into the variator casing (Fig. 2) and only brought into operation when a lost-motion x has been taken up when the friction disc variator joke 8 is moved to its greatest reduction ratio (i.e. lowest gear) whereby the valve unit 17 is adjusted to increase the servo-pressure at 11 to accommodate increased torque effected by the torque converter during its initial torque multiplication phase, as follows. When the yoke 8 is moved, as stated above, to take up the lost motion x and move into its position shown in full in Fig. 2 giving the greatest eccentricity e of the friction discs 5, 6 for the greatest reduction ratio, and the increased torque via the converter multiplication phase becomes operative, the yoke 8 inwardly moves the spring-loaded plunger 38 to rock the bell-crank lever 33 and thus lower the pivot 32 of the plate 26 to alter the effective points of contact on the plate 26 of the push rod 27 and slide 23. The resulting change of ratio of their effective distance to the pivot 32 in the plate 26 from a/b in Fig. 3 to the larger ratio a<SP>1</SP>/b<SP>1</SP> in Fig. 4 thus further modifies the effect of the orifice 24 to correspondly increase the friction disc engaging pressure in the line 12 to the servo 11 for the higher engaging pressure during the torque multiplication phase of the converter.
