Abstract: An automatic cut-out has an additional arc loop in the region of the contact point (41) which is formed by an arc conducting rail (16, 33) and an additional conducting rail (31), which are connected to one another by means of rectangular connecting lines (35, 36, 37) which connect essentially laterally adjacent to the arc conducting rail and are located essentially in the region of the switched-off position of the moving contact piece (20). In this way, after opening of the contact point (41) and commutation of the base of the arc from the moving contact piece (20) to the arc conducting rail (33, 16) currents are made to flow in each case parallel and in the same direction with respect to one another both in the additional conducting rail (31) as well as in the arc conducting rail (33, 16), by which means it is achieved that the base of the arc is accelerated into an arc quenching plate stack. <IMAGE>

Abstract: The invention relates to a device for positioning an exploratory probe in space, for example an ultrasonic probe. This device comprises an essentially rigid arm (20) whose first end (21) is articulated relative to a support holder (10) by two perpendicular articulation spindles (24, 26) and the exploratory probe (2) is mounted on a support element (30) connected to the second end (22) of the arm by at least two articulation spindles (32, 34). The support element (30) of the exploratory probe is connected to the second end (22) of the arm by means of a set of four articulation spindles (32, 34, 36, 38) which are successively disposed perpendicular to each other and in space in such a manner as to occupy a limited volume in the immediate vicinity of the exploratory probe. This device thus offers an ability for unlimited positioning in space of the exploratory probe within a space or volume which is limited or confined, which constitutes an essential technical advantage for locating targets such as concretions, renal or biliary calculi with a view to their destruction. <IMAGE>

Abstract: A flutter exciter induces vibration either for actual aircraft flight testing or for wind tunnel model testing. The basic flutter exciter unit is a pair of rotatable concentric cylinders mounted on either a fixed vane or an aircraft wing or a tail surface. Each cylinder has a slot which allows the air flow to pass therethrough. By rotating the cylinders together, oscillating air pressures are induced on the fixed vane or the aircraft surface to which the cylinders are attached. The cylinders may be mounted at a trailing edge of either the fixed vane or the aircraft wing, to any tail surface, or on any other lifting surfaces of the aircraft itself. Thus, because the flutter exciter can be made as a completely self-contained unit, it may be simply mounted to any suitable hard point on either the test model or the aircraft. The power required to rotate the slotted cylinders is minimal, thus allowing the use of a low wattage motor.

Abstract: A control system (10) for motor vehicle gear-changing transmissions (12) is provided having a manually operable device (28) and an automatic device (30, 34), in each case for generating gear-change control signals. The gear-change control signals are supplied to the force-driving devices for the plurality of windings of a stepping motor in order to switch selected windings on intermittently. When switching a winding on, a reverse current is also triggered which causes the automatically operating device (30, 34) to generate a fault signal if no reverse current is generated by the selected winding. If a fault signal occurs, the generation of further automatic gear-change control signals is suppressed so that transmission gear changes can be carried out only by the application of manually generated gear-change control signals.

Abstract: A  beta -galactosidase complementation assay for determining the presence of an analyte which is a member of a specific binding pair (sbp) in a sample is provided, which assay permits visual discrimination between those samples wherein the analyte is present above a predetermined, threshold concentration. The method comprises combining the sample with a hydrophobic enzyme donor- (ED-) analyte conjugate and the complementary member of the sbp to form an sbp complex-containing assay medium. A small volume of the assay medium is spotted onto an enzyme acceptor (EA) affixed to a bibulous, solid support, followed by development with enzyme substrate solution. A substantially larger area is detectable when analyte in the sample is below as compared to above a threshold concentration. The assay is particularly useful in field testing applications such as determining the presence of antibiotics in milk, toxins in water, or drugs in serum or urine. Kits facilitating the method are also provided.

Abstract: Upper and lower sections 8, 9 are formed on an endless belt 2 by means of deflection rollers 12, the belt being maintained in revolution by a drive. Sludge water is charged to the upper section of the belt, which comprises a multi-layer web 6 resting on a carrier web 4. The layers of the web 6 forming a transmissivity pack consist of a fibre mat and have different thicknesses, so that the sludge water encounters a filter layer which is adjoined by a discharge layer of lower density. The high water permeability of the transmissivity pack leads to efficacious separation of water from the sludge particles and hence to pre-thickening to increased values of dry solids content. <IMAGE>

The output signals of the two comparators (7, 8) are combined to form a status signal (UStat). The proposed circuit makes it possible to detect both a shortcircuit or shunt on the load and a leakage current of the power transistor (1) and an interruption in the load or its feed line.
