The contact element is arranged spaced apart from the resistor network, and the magnetic element can be moved relative to the resistor network and the contact element. An electrically conductive connection can be established between the contact element and the resistor network by deflecting the contact element. A plastic spacer element is arranged between the resistor network and the contact element and is hot-swaged to the resistor network and/or to the contact element.

Abstract: A vehicular pointer-type residual quantity meter comprises: a display panel that has a scale part which allows a driver to recognize a residual quantity, and a non-scale part that differs from the scale part; a pointer unit that is disposed behind the display panel; a pointer driver body unit that carries out a movement of the pointer unit in a real space; and a control unit that controls the pointer driver body unit in so that the pointer unit indicates one of metering regions in the scale part in replay to a current residual quantity. The control part controls the pointer driver body unit so that when the residual quantity decreases to zero, the pointer unit moves from a metering region corresponding to a zero residual quantity in a direction opposite to a metering region corresponding to a residual quantity value greater than zero to the non-scale part of the display panel.

Abstract: A wildlife conditioning and suppression system conditions wildlife to avoid a restricted area. The system relies on backing up predetermined and repeatable warning stimuli with real enforcement directed against the wildlife. In a preferred embodiment, a warning zone is defined around a protected area and predetermined sensory warning stimuli are produced each time wildlife enters the warning zone. If the wildlife enters the protected area, physical enforcement by means of a water cannon is used to eject the wildlife from the area. The wildlife is thereby conditioned to avoid the area by means of repeatable warning stimuli backed up with real enforcement.

A rotatable fluid responsive actuator is magnetically coupled to the indicia bearing member such that a magnetic force, which varies as a function of the fluid induced position of the actuator, is imposed on the indicia bearing member. At a critical level of the fluid, the imposed magnetic force overcomes the gravitational force and the indicia bearing member moves to a second position.

Abstract: In a light powder granule treating system, a light powdery granule supplying member is connected to a light powdery granule treating member through a supply conduit, and a sensing member is arranged for detecting the light powdery granules being so stagnant within the conduit as to form a massive flow of a thickness which exceeds a predetermined value. When the sensing member detects the stagnant light powdery granules, it generates a detection signal which in turn stops the light powdery granule supplying member from operating.

Abstract: A reservoir (20) for a master cylinder (16) has a body (22) with an end member (82) attached thereto by tangs (92, 92' . . . 92.sup.N) that engage a surface (69) on a flange (70). A shoulder (86) concentric to peripheral lip (84) on the end member (82) retains a seal (96). A projection (90) that extends from the end member (82) acts as a stop to assure that a pin (52) on a lever (54) that carries a magnet (60) remains attached to arms (44) extending from the body (22). While motion may move the fluid in compartments (34 and 36) toward flange 70, shoulder (86) acts a first barrier and seal (96) acts as a second barrier to prevent fluid from leaking through the mechanically formed joint. If fluid is lost from the compartments (34 and 36) a float (58) tracks the fluid level and moves magnet (60) toward sensor (64) to inform an operator of the change in fluid level.

Abstract: A wedge shaped hollow float is mounted by one end to a channel bolted to the inside of the sloping roof of a grain bin approximately two feet from the top thereof. A curved rod is pivotally secured by the inner end thereof to the other end of the float and extends through the channel and through the roof and has an indicating disc on the outer end thereof. As the bin fills, the angle of repose of the grain engages the other end of the wedge shaped float and gradually lifts it as the bin continues to fill. When the indicator is fully extended, a rod and disc indicates to the operator that the flow of grain to the auger hopper should be shut off and the two foot space at the top of the bin is sufficient to hold the grain left in the auger and in the hopper thus avoiding any spillage.

Abstract: The soap solution dispenser contains a reservoir into which opens an outlet or outflow opening of a container. In the reservoir there is present a float body or float which is pivotably mounted and provided with at least one indicator flag. Conjointly with the drop of the liquid level in the soap solution reservoir the float body also descends, which causes a displacement of the indicator flag. During the lowering of the surface of the soap solution the indicator flag moves along a viewing window formed in a cover or covering hood. There is thus signalled or indicated that the content of the soap solution in the reservoir is quite small or nearly consumed, so that the container now should be exchanged. One resulting advantage of the invention is that the indicator flag moves externally of the soap solution, so that the indicator flag cannot become stuck or bind, and thus, always remains readily visible.

Abstract: A direct indicating automatic stop fill valve is mounted to the inlet to an LPG tank whereby inlet ports to the tank volume are covered by a slidably mounted cylinder which is raised through contact with a float/cam arrangement until the tank level reaches a predetermined level. The cylinder is then driven into a sealing position to stop the flow into the tank by a differential pressure force resulting from the inlet pressure being higher than tank fluid pressure. The cylinder also supports a drive magnet for actuating a gauging mechanism to visibly indicate the open or closed status of the stop fill valve.
