Abstract: An ultrafiltration apparatus in which a plurality of support panels are arranged to form a stack, with panel faces each carrying a membrane for separating a base liquid into two fractions. Apertures are formed in the panels, and the stack is arranged so that these apertures are in registration to form ducts within the stack. Longitudinal ribs are formed in the panel faces, with longitudinal channels on either side of same. Transverse ribs are formed between adjacent longitudinal channels, with transverse channels between adjacent such ribs. Turbulence reduction flanges are inserted between selected panels within the stack to divide same into subassemblies, which direct fluid flow from the top of one subassembly to the bottom of the succeeding subassembly, providing bottom-to-top flow across the panel faces throughout the stack. The fraction of base fluid that flows through the membrane is collected in the transverse channels and thense flows in the longitudinal channels to a permeate extraction duct, where such permeate can be extracted.

Abstract: A slip-controlled brake system for road vehicles with four-wheel drive which are fitted with differentials (2) and differential locks (3,4) is proposed. When the anti-lock system is functioning the differential locks (3,4) are switched off. When the differential locks (3,4) are subsequently switched back on, it is ensured that at least the accelerator pedal is not operated. In this way damage to the transmission or drive train is prevented when the differential locks (3,4) are switched back on. <IMAGE>

Abstract: In order visually to indicate the existence of a "continuation" current through a lightning arrester, an indicator is associated therewith, which is formed by an elastically deformable strip maintained retracted against capsule electrode by a retention mechanism which is associated with an electrical filter which causes fusion of a fusible wire under the effect of a "continuation" current. Once its end is released, the strip projects outwardly of the lightning arrester and marks the location of the defective insulation.

Abstract: In an information recording and reproducing apparatus using a disc-shaped information recording medium having a plurality of recording tracks, each of which recording tracks is divided into a plurality of sectors, to record and reproduce information on and from the information recording medium on a sector-by-sector basis, when a target sector (Sn) is detected to be a defective sector whose address can not be reproduced, in the first place, a reference sector (Sn-k), which is positioned preceding the defective target sector and whose address can be reproduced, is detected. Then, a rotational latency time from the detected reference sector (Sn-k) to the defective target sector (Sn) is measured by using:   (l) a time measuring circuit (l3) for measuring the rotational latency time per se; or (2) a counter circuit (l4) for counting the number of a sector mark or sector marks (ll) which indicate the presence of an associated sector or sectors and which are detected during the rotational latency time, so that the defective target sector (Sn) may be taken to be a normally detected target sector whereby information may be recorded and reproduced on and from the defective target sector (Sn), thereby making it possible to perform recording and reproduction of informa tion on and from a defective sector whose address can not be reproduced.

Abstract: A cardiac valve prosthesis in which the inner area of the valve ring has an internal cross section continuously decreasing in flow direction. The valve ring is shaped like a nozzle, and flow disruption occurs only at the nozzle end, allowing a concentric flow discharge. Vortex formation at the jet boundary and inside the flow is inhibited. As a result, flow resistance is reduced and blood damage is minimized. A flushing channel traverses the joint cavity in order to avoid deposits of blood particles in the valvular joint.

Abstract: A self-locking fastener having a bearing surface comprising a plurality of sets of serrations (13) arranged to penetrate a workpiece such that, while a resistance to the loosening of the fastener from the workpiece is created, the marring of the workpiece surface is minimized. Use of the fastener is particularly advantageous if the workpiece consists of soft materials such as cast-aluminum or non-heat treated carbon steels. Each set of serration (13), when viewed as a profile, includes a downwardly inclined surface, a relatively deeper serration and a relatively shallower intermediate serration. The intermediate serration controls the depth of the penetration into a workpiece.

Abstract: An injection moulding machine has a closure unit which holds either a first mould with a central gate and central cavity or a second mould with central cavity but non-central gate for an asymmetrical sprue; it has also an axially moving/driven injector unit, mounted on a block on the frame, and a base block to take the plasticating barrel and drive system for the screw. An arrangement moves the injector from one operating position with a central injection axis for the first mould round to a set second position (at least) for the second mould in a pivoting plant passing through the central axis of injection. The mounting block holding the plasticating barrel in a sliding seating can be locked in position; this block and its support can be moved back by the unlocked but axially halted barrel; it pivots about a point at the back and between parallel faces on the support. It can be moved into a position opposite that for injection where pressurised melt from the barrel flows out of the nozzle and beyond the bore which is extended in the direction of injection; it flows to a point on the mould support from which solidified polymer can drop off for disposal.
