Title: Trolley brush
IPC: B60L5/08
Filed: 1991-04-26
Abstract: A current collector for contact lines has a base part (1) to which an arm (2) is coupled, which arm bears the sliding contact carrier (3). The base part (1) is provided with a slot-like recess (6), whose plane extends in the plane which is formed by the longitudinal axis (13) of the arm (2) and a first swivel axis (A) of the arm. This recess (6) is bounded by a wall part (7) which has a spherical cap (10) towards the recess (6), in which cap a crowned projection (11) of the arm (2) engages. Between the base part (1) and the arm (2) a spring (4) is arranged which holds the projection (11) in engagement with the spherical cap (10). In this way, the arm (2) can be swivelled about the swivel axis (A) and in the plane of the recess (6) counter to the spring force.

Title: Cellular and serum protein anchors and conjugates
Inventor: POULETTY PHILIPPE
IPC: A61K47/48
Filed: 1994-09-16
Abstract: Novel bifunctional reagents useful in providing extended in vivo lifetimes of physiologically active agents are provided. The reagents comprise conjugates of a first binding member specific for a target in a mammalian host, such as a toxin, drug of abuse, microbe, autoreactive immune cell, infected or tumourous cell, antigen presenting cell, or the like, joined to a second binding member specific for a long-lived blood component, including cells, such as an erythrocyte, platelet or endothelial cell, and plasma proteins. These conjugates find use by extending the lifetime and availability of the target binding member for coupling the target and the blood component and thereby reducing the concentration free target, modulating the volume of distribution of the target, targeting the target to sites of enhanced immune response, facilitating target clearance from the bloodstream, or extending the stimulation of an immunogen.
Patent AU-8207487-A (AU)
Title: Electrical heaters
Inventor: BREMNER ROBERT
IPC: H05B3/14
Filed: 1987-12-03
Abstract: A system for automatically disconnecting a conductive polymer heater if an arcing fault occurs. A sensor conductor (4) is incorporated into the heater, so that if an arcing fault occurs, the current through the sensor conductor increases and triggers a safety circuit to disconnect the heater. As illustrated in Figure 1, the sensor conductor is preferably insulated by an organic polymer (5) which pyrolyses if an arcing fault occurs and thus permits current to flow between the sensor conductor and an electrode (1) of the heater.

Abstract: The invention relates to a mandrel (13) for centering a workpiece (48) in a machine tool (1). The mandrel (13) comprises two parts, namely a centering element (24) and a clamping element (22), which can be locked together. The centering element (24) is fitted in a fixture element (41) supported on the machine tool and incorporates pneumatically controlled centering devices (33, 35). The centering element (24) is fitted in the fixture element (41) in such a way that a positive pressure occurs between the centering element (24) and the fixture (41), resulting in dust and dirt being kept away from the bearing. The diameter (a) of the portion of the centering element (24) which is fitted in the fixture (41) is independent of the diameter of the workpiece (48) which is to be machined. This means that the centering element can be stably fastened in even when workplaces (48) with small-diameter holes are machined.
