An invention is described through which it is possible to reduce in quantity the coloured, mostly dark, and frequently adhesive deposits which form in lead accumulators with separators of filled poly-olefins during formation and operation. The essential feature is that the separators contain as plasticizer a process oil with a CA value of ? 6 %, a sulphur content of ? 2000 ppm and a polar part of ...

A device for wheel-chairs with a frame (1), driving wheels (2) and a seat which can be raised and lowered. According to the invention the device comprises at least one pair of parallel arms whereby the seat (5) can undergo parallel displacement in the height direction in relation to the frame (1) by means of a device (20, 21, 22) for turning of the arms (10, 11) in relation to the frame (1).

A tire building apparatus comprising: an extruder having an extrusion die comprising a doughnut-shaped die member and an axially elongated die member to provide for consecutively extruding a cylindrical-shaped material downwardly from space between the doughnut-shaped die member and the axially elongated die member; a tire supporting unit for supporting a green tire into which the cylindrical-shap...

PURPOSE:To detect a fault of an interval timer by setting different values alternately to plural interval timers, then monitoring the corresponding time-up end signals. CONSTITUTION:When either one of interval timers 2 and 3 has a fault, no time- up signal is obtained from the faulty timer. Thus the output of a flip-flop 11 is fixed at a set or reset state and then changed into a DC output. As a r...

PURPOSE:To shorten the time required for injection and to improve the work efficiency by holding in advance spare liquid crystal material in a defoamed state in a second vacuum tank, supplying it to an injection bowl in a first vacuum tank and executing injection to a liquid crystal panel. CONSTITUTION:At the time of executing injection, first of all, a liquid crystal panel 2 is set onto an inject...

A method for regulating the flow of liquid metal to an atomization zone is provided. The regulation is effected by imparting a high density flux to a stream of liquid metal as it descends toward the atomization zone. The high density flux is applied by a flux concentrator. The flux concentrator is a small sleeve-like element attached by parallel conductors to a larger sleeve-like element which act...
