Abstract: 1414537 Piezoelectric transducers COMMISSARIAT A L'ENERGIE ATOMIQUE 11 June 1973 [15 June 1972] 27711/73 Heading H4J Apparatus for picking up acoustic signals emitted by metal rods, wires or fibres 15 under tension comprises a piezoelectric ceramic cylinder 6 having internal and external metal coatings 7, 8. Two end plates 10 secure a cyclindrical metal casing 9 around the cylinder 6 without touching it. Rubber rings 14 are preferably also provided to maintain a constant air-filled space 12 between cylinder 6 and casing 9. A cover 13 of sound permeable material seals the air-filled space 12. A rod 2 is secured to the casing 9 and terminates in a co-axial connection 5 (Fig. 3). Rod 2 contains two conductors 3, 4 connecting between the metal coatings 7, 8 and the coaxial connection 5. In use, the apparatus is in a liquid-filled tank 16 and the rods, wires or fibres 15 are coaxially arranged in the cylinder 6. Rod 2 is mounted on the tank 16 by an acoustically insulating ring 19 and a device 26 allows for adjustment to provide the coaxial arrangement. The rods, wires or fibres 15 are held between a stationary head 20 and a head 21 secured to a device 18 for exerting tensile stress. The base 22 of tank 16 is connected to head 21 by a bellows 23. Device 18 is preferably of the kind in which water flows into a vessel 25. The coating 13 is resistant to corrosion by the liquid 17. Cylinder 6, preferably of barium lithium titanate has a radial resonance of 185 kHz and the device, uses the response in the region of this resonance frequency.

Class 100(2) A rotary printing machine in which its rotating parts are locked in predetermined angular relationship by a drive mechanism carried by frame parts 14, 15 relatively movable apart to separate certain of the rotating parts, has a supplementary transmission which permits separation of the frame parts whilst maintaining the angular relationship of the rotating parts. As shown, a rotary multi-colour offset machine has an impression cylinder 1 co-operating with blanket cylinders 2, 3 co-operating respectively with plate cylinders 4, 5. The cylinders 1...5 are driven through gearing from gear wheels 12, 13 driven by a chain 11 and motor 10. In order to provide access to the cylinders 1...5 and inking and damping mechanism 6, 7 and 8, 9 the frame parts 14 and 15 are moved apart by a double acting hydraulic ram 35 e.g. operated as described in Specification 815,811. The part 15 is mounted on rollers, not shown. The gearing driving the cylinders is maintained in correct angular relationship while the parts 14 and 15 are separated by gears 17, 18, 21, 23, 24, 25, the gear 25 engaging a gear on the cylinder 5. The gear 21 is carried by a sleeve 19 keyed to a shaft 16 to permit sliding thereon.

In a motor vehicle centrifugal clutch having additional control mechanism the rate of engagement is controlled by an hydraulic cylinder having a spring-loaded needle valve actuated by depression on a diaphragm and a non-return valve. The rate of engaging movement of a clutch thrust race 25, under the control of a vacuum servo diaphragm 15, is determined by the rate of flow of hydraulic fluid to a cylinder 1 through a fixed orifice 19 and a needle valve controlled orifice 18. The orifice 18 has a controlling needle 5 loaded to full open position by a spring 9 and urged towards closed position by a diaphragm 8 connected on its underside to the engine manifold depression. Rapid disengagement is provided by a non-return valve 6 allowing fluid from reservoir 10 to flow freely to the cylinder 1. Clutch engagements at small throttle openings are thus slow and at large openings fast. In a modification, the piston 2 is used as a master piston in an hydraulic clutch control servo system utilizing the reservoir 10 for both the engagement control and servo system fluid.

Abstract: 381,343. Canning or bottling under vacuum. CHORLTON, F. O. L., Riverside Works, Bury. Oct. 16, 1931, No. 28743. [Class 49.] The invention relates to that type of machine for sealing lids or stoppers on cans or bottles in vacuo in which the can &c., 13 is supported on a table 12, which is vertically movable within a sealing cylinder 5 positioned below the sealing chamber 11, and which moves up into the sealing chamber where a lid is sealed on the can &c., the sealing cylinder 5 sliding vertically within an outer support. According to the invention means of a variable-leverage character is provided whereby the extent of lift of the sealing cylinder is automatically adjusted with the adjustment of the distance of the table bracket 3 below the sealing chamber. As shown, one arm of a bell-crank lever 1 pivoted on a pin 2 having an eccentric part 2x is connected to the sealing cylinder 5 by a link, or links 6, the other arm being impinged against by a bowl 7 revolubly mounted on a rod 8 sliding in bearings on the frame 4 and receiving motion from a cam 9. When a vessel taller than that shown in the Figure is to be sealed the bracket 3 is lowered to accommodate it, the pin 2 being thus brought nearer the bowl 7 and a greater movement being imparted to the lever 1, which thus transmits the greater lift necessary for the increased height of vessel.
