Abstract: A static mixer comprises a conduit for transporting flowable material, and a plurality of stationary mixer elements which so deflect the flow of material that a thorough mixing is effected. Each mixer element comprises seven plate members: a diamond-shaped plate (34); two triangular plates (48,50), co-planar and perpendicular to the diamond-shaped plate, the base of one triangular plate providing a leading edge to divide material flow into the conduit into two separate flows; and four deflector plates (66,68,70,72), which join the diamond-shaped and triangular plates and conform to the contours of inner walls of the conduit to provide two separate flow paths. The flow paths are substantially helical and rotate through substantially 180 degrees from the leading edge to trailing edge of each mixer element to rotate and thoroughly mix individual flows through the element. The leading edge of each succeeding mixer element is angled relative to the trailing edge of the immediately preceding mixer element to obtain successive division, mixing and recombination of flows.

Abstract: Continuously variable combined transmission with a hydrodynamic unit (1) at least in three parts, provided with an adjoined bridge coupling (11) and with a continuously variable mechanical transmission (2), wherein the continuously variable of the rotation torque is achieved by means of the continuously variable mechanical transmission (2) and wherein the inversion for the reverse and forward running, as well as this starting in these two operation modes are carried out by the hydrodynamic unit (1). The stator (14) of the hydrodynamic unit is secured to the input shaft of the continuously variable mechanical transmission by means of a coupling (4) or a unidirectional coupling (15). In the forward running operation, as well as in the short starting phase, the hydrodynamic unit (1) effects the bridging. This switching is achieved as a function of the rotation speed and may further be influenced as a function of the rotation torque. In both operation modes, the continuously variable mechanical drive (2) is in a position for transferring the maximum rotation torque. The brakes (3) and the clutch-couplings (4) may also be designed as claw couplings with synchronisation device.

Abstract: Standard engineering shapes or profile elements are united by screw clamps to form a releasable and adjustable boom arm or cantilever arrangement. By means of quadrangular clamp bodies, substantially vertical support arms carrying seating or reclining means for a person are mounted on a horizontal support arm and can be individually adjusted in relation thereto. The boom arm is mounted in a further screw clamp provided in the free end of a hydraulic cylinder and piston assembly and is therefore capable of being raised and lowered and swivelled about the lengthwise axis of the cylinder. A hand-grip capable of being pivoted away is provided for the safety of the occupant. Boom arms of this type are employed in bathing installations to safely transport patients and invalids into and out of bath or the like tubs. The releasable and adjustable design concept of the boom arm permits it to be dimensionally adjusted during its initial installation, so that preliminary dimensional surveys are superfluous. In service, the boom arm can be readily adapted to modifications of building or apparatus, changed methods of treatment and varying ergonomic requirements. This provides an increased degree of flexibility and adaptability in application in comparison to welded constructions and therefore greater economy.

Title: A data processing system incorporating an automatic reset arrangement

Granted: 1988-01-13
Abstract: Cartridges for a microcomputer have two adjacent edge connectors replaced by a single connector (14) with a projection (29) which passes into the area in which the adjacent connector would normaliy be placed. When the cartridge is inserted or removed from the connector socket (3) in the microcomputer, the projection transiently shorts a pair associated socket contacts (27,28). A fixed potential (for example earth potential) normally applied to the main portion of the edge connector from its associated contact (28) of the pair is therefore transferred to the transiently contacted contact (27) to provide a reset signal for the microprocessor of the microcomputer. Thus, the microprocessor is reset each time a cartridge is inserted or withdrawn.
