Abstract: A fastener for sliding doors or windows comprises one or more bolt assemblies (8) having sprung loaded bolts with heads (15) mounted in housings set into the stile (7). The fastener also comprises a receiver assembly (9) including a pair of rails (23, 24) having similar aligned key-hole openings (25, 26) respectively. The outer retainer rail (23) is slidable relative to the inner rail by operation of an actuator (27) controlled by a handle assembly (10). When the bolt heads (15) are received in the aligned openings (25, 26) on closing of the stile (7) to the jamb, the handle (29) of the assembly (10) is turned causing the retainer rail (23) to move downwards to trap the heads (15) of the bolt in the narrower parts of each opening (25) in the retainer rail (23). The handle assembly (10) preferably includes a lock to prevent the handle (20) being rotated after locking. The spring loaded bolts provide a "buffer" action and prevent damage to the receiver assembly even if in the fastening position. The bolt assemblies may be mounted on a jamb with the receiver and handle assemblies on the stile.

Abstract: A batten which is made of a plastic profile, that seen on a transverse sectional view, consists of several cavities next to one another, in order to hold close fitting inserts. In this manner it can be obtained that the stiffness of the batten is changing gradually, because the reinforcing inserts in the cavities have a different length. The stiffness of the batten can be changed in a simple way and right along its full length. The profile and rod-like inserts are substantially constant in cross-sectional dimension throughout their length and consequently easy and cheap to manufacture.

Abstract: Halogen is produced by electrolyzing an aqueous halide in a specially designed cell. The cell comprises an analyte chamber and a catholyte chamber separated by a permeable membrane or diaphragm, notably an ion exchange (generally cation exchange) polymer. At least one electrode comprises at least two sections. One section comprises a gas and electrolyte permeable layer, sheet or mat having a catalytic surtace, i.e. one having a low overvoltage, (low hydrogen overvoltage if the cathode and low halogen overvoltage if the anode). This layer is spaced from themembrane by a second portion comprising an electroconductive resiliently compressible layer or mat, which is in contact with the membrane on one side thereof, the other side thereof being in contact with the main cathode. This second or spacer section advantageously has an electrode surface having a higher overvoltage than the first electrode surface. Preferably the cathode has the above construction. Upon electrolysis of alkali metal chloride or other halide in such a cell and with a cathode of the type described above, a low voltage is obtained even at high current densities and the cathode efficiency is high.

Abstract: An apparatus is arranged such that, in positioning an electric discharge machining electrode, the contact between a tool electrode (P) and a workpiece (W) is detected by applying positive and negative voltages in the form of pulses between the tool electrode (P) and the workpiece (W) through a pulse transformer (PT) and detecting the applied voltages. The voltages detected through detecting electrodes (A, B) are passed through an absolute value circuit (1) and a smoothing circuit (2) and are compared with a reference voltage (VL2) in a comparator (C2). The contact between the tool electrode (P) and the workpiece (W) is detected from the output of the comparator (C2). Since the mean value of the applied voltages is 0, corrosion due to electrolysis does not occur, and positioning errors due to the coulomb force are not produced either.
