Abstract: A method for reducing elongational viscosity of an elastomeric composition includes adding at least one elongational-viscosity-reducing additive to the elastomeric composition in an amount so that the elongational viscosity of the elastomeric composition, measured at 120° C. and at a shear rate of at least 1000 sec<SUP>-1</SUP>, is at least 10% less than the elongational viscosity, measured at 120° C. and at the shear rate of at least 1000 sec<SUP>-1</SUP>, of the elastomeric composition without the at least one additive. A process for producing a tyre includes feeding an elastomeric composition to an extruder; forming, by extrusion, the elastomeric composition as a continuous elongated element; and depositing the elongated element on a support in a plurality of coils to make up a structural element of the tyre. Forming the elastomeric composition is carried out at the shear rate. The elastomeric composition comprises the at least one additive.

Abstract: The manually operated handbrake or parking brake e.g. for a motor vehicle consists of a cable linkage (20,21) which is connected to one end (17) of a 180 deg. crank arm (16) e.g. in drawn wire or rod material. The other end of the arm (12) has a longitudinal groove which locates a pivoting cam (10). As the arm is rotated, the cam acts on the end of a cylinder (7) which pushes the cylinder and brake pad support (5) into contact with the brake disc. A wire spring (11) returns the arm to its original position and a coil spring (9) returns the actuating cylinder to the released position. A flexible rubber gaiter (24) protects the lever mechanism from ingress of dirt and dust.

Date May 27, 1993In a plastic clip which serves to close sausage casings, bags or the like and consists of two interlockable parts (1, 10), at least one part (1) consists of an elongate frame, which has side bars (2), which have a large height in relation to their wall thickness. The side bars (2) are provided with central recesses (4), into which the end of the wrapper, which end has been gathered to form a tip, can be inserted. The other part (1; 10) together with the first part encloses the wrapper and that has been gathered to form a tip. At least the other part (1; 10) is provided with a projection, which consists of a rib (13), which extends parallel to the side bars and protrudes into the interior (5) of the frame. That projection deflects the tip in wave shape and applies pressure to the tip at the same time. For this reason, the clip will have a maximum elastic yieldability and, as a result, a maximum adaptability to different tip thicknesses or different pressures in the closed interior space in conjunction with a strong and uniform seal whereas the firm detent connection is not adversely connected. In a first embodiment the two clip parts are identical. In a second embodiment the first part encloses the tip by a U-shaped recesses, which are formed in the side walls and closed by the second part.

Abstract: A shaft (44,144,145) is conventionally driveably connected to a bore (46,146) by a steel key of rectangular cross-section. Where the shaft is of smaller diameter than the bore, a slotted nylon sleeve is fitted between them and a tall steel key extends through the slot. Failure of both standard and tall keys can occur for various reasons. A unitary component (50,162,163) of suitable plastics material or non-ferrous metal is therefore proposed. This component essentially includes an integral key (56,174) of curved cross-section adapted to engage in a mating keyway (176) formed in the bore. Where the shaft (44) and bore (46) are nominally of the same diameter, the component (50) consists also of an integral key (52) of rectangular cross-section adapted to engage in the conventional keyway (48) in the shaft. Where the shaft (144,145) is of smaller diameter than the bore (146), the component (162,163) also includes a sleeve (164) with the key (174) of curved cross-section formed on its outer periphery, and a keyway (170) of rectangular cross-section formed in its inner periphery and adapted to be driveably connected by a separate standard key (171) to the conventional keyway (148,149) in the shaft. The component is useful in the flange-mounting of different electric motors on off-the-shelf gear units. <IMAGE>

Abstract: A process and assembly denitrifies dried tobacco leaf (R, R') in Burley rib form which is: (a) inserted into the chamber within a housing (9), (b) brought into contact with a solvent (12), and (c) then discharged from the housing (9). The novelty is that: (d) the housing chamber is pressurised and; (e) the tobacco leaf (R, R')is transported through the chamber and solvent bath (12) by a helical conveyor (2). Also claimed is that the solvent (12) is water and that the chamber is heated to between 100-130 degrees C., pref. 118 degrees C. The tobacco is passed through the chamber (9) in a continuous process in which there is constant exchange of the water (12) which consists in the chamber of a liq. phase (12), and the gaseous phase (13) which is introduced to the chamber. The tobacco residence period in the chamber is adjusted by regulation of the conveyor rotation speed. The ratio of the mass flow of dry tobacco in Kg to that of the solvent in Kg is in the range 0.5-0.031, pref. 0.25. The tobacco is subsequently subjected to a further rinsing under a water shower. The pressure maintained in the chamber is 1.5 to 3.0 bar, pref. approx. 1.9 bar.
