Title: Detachable connection between cylindrical parts
Inventor: BARANEK WERNER
IPC: F16B9/02
Filed: 1986-11-06
Abstract: A detachable connection comprises a cylindrical part (3) secured in a cylindrical bore (4) in a part (1) by the use of an expander pulling bolt (6) which is introduced into a cylindrical recess (5, 20) in the part (3) to expand the latter. The bolt (6) comprises a pressure region (7) of relatively larger, constant diameter and a guide region (8) of relatively smaller diameter, compared with the diameter of the recess (5, 20) and also a conical expander region (9) joining the pressure and guide regions. The arrangement is used in securing adjacent end members (22, Fig. 6) of a traction chain of an excavating vehicle; securing a threaded axle in a seat; and securing an axle in a train wheel hub. Bolt (6) is inserted in the recess, region 8 first, by a pressing tool, or by hammering. Bolt 6 is pushed out of the recess by a socket tool inserted through a hole (10) in bolt (6) to engage a socket (18) in a screw (15) to displace the screw (15) towards bolt (6) to press on its guide region (8). <IMAGE>

Patent GB-2196269-A (GB)
Title: Duplex filters
Inventor: RADMALL PAUL
IPC: B01D35/12
Filed: 1987-10-29
Abstract: A duplex filter comprises two filter units 70,71 and a system 85 to 88 which monitors the pressure drop across the unit in service and automatically moves valve 74 to switch the flow through the other unit when the first unit clogs. The filter elements in the respective units are cylindrical and axially aligned in their housings on opposite ends of a cylinder 93 (Fig. 4). When the main flow of fluid from inlet 75 to outlet 80 is switched to a clean filter unit, e.g. unit 71, the piston 92 is caused to move the length of cylinder 93 in a time determined by restriction 109 (or 108). Piston 92 carries a hollow rod 95 extending into each filter element and carrying therein respective spool-like nozzles. As the piston moves, filtrate flows into the nozzle of the unit in service, through rod 95 to the nozzle of the clogged filter unit, and the filtrate flow rotates the nozzle by reaction jets at the same time as other jets direct filtrate on to the filter element, to backwash it for the time taken for the nozzle to move the length of the element. <IMAGE>

Title: Low leakage A.C. proximity switch circuit
Inventor: HARRIS GEOFFREY JOHN
IPC: H03K17/95
Filed: 1989-06-23
Abstract: The circuit operates a main switch (TH1) to pass an A.C. supply through an external load when a metallic object is in proximity to a coil (L1) driven by an oscillator circuit including transistors (T1, T2) which is connected to a level detector circuit including transistor (T3) and controlling TH1. Upon initial application of the A.C. supply, the level detector circuit is overridden by a time delay circuit including capacitor (C3) and transistor (T4) until a predetermined period of time has elapsed, so as to prevent the generation of erroneous "on" signals before the oscillator has stabilised. Transistor (T4) conducts and clamps the output of the level detector until the current flowing in (C3) has reduced to a sufficiently low value for transistor (T4) to turn off. The circuit is powered by a power supply stage including storage capacitor C7, the charging current thereof being controlled by a transistor T10 and MOSFET T11 to a predetermined maximum value when the switch is "off". <IMAGE>
