Abstract: Circuit apparatus for supplying a loop current to a two conductor loop telephone line includes first and second differential amplifiers (11,14) each having the same gain factor. The first amplifier is coupled to one side of the line via a series resistance (12), while the second amplifier is coupled to the other side of the line via a series resistance (15) of the same magnitude. A feedback amplifier (16) has one input terminal coupled to one side of the line and another input terminal coupled to the other side of the line. The output of the feedback amplifier is coupled to the input of a variable gain amplifier (21) which has its output coupled to an input terminal of the first differential amplifier (11). The first differential amplifier receives a voltage reference source at its other input which source controls the magnitude of the current supplied to the line circuit. To accommodate different system characteristics, the gain of gain controllable amplifier (21) is varied which effectively varies the equivalent feed resistor for the subscriber line.

Abstract: A manual starter crank has an integrated safety device providing protection against backfiring during starting of an internal combustion engine. The manual starter crank has a starter shaft which, when turning in a starting direction, engages the free end of a cam shaft of the internal combustion engine. The safety device is integrated into the casing of the manual starter crank and includes a ratchet with a pivot axis which is approximately parallel to the starter shaft. In the engaged position of the ratchet, a free end thereof engages an abutment surface on the starter shaft, whereby the manual starter crank is connected in torque transmitting relation with the engine cam shaft when the crank is turned in a starting direction. The safety device includes a disengaging bushing surrounding the starter shaft and which is mounted on a bearing support by a one-way clutch and presents a disengaging pin in the path of movement of the ratchet. The disengaging pin cooperates with the ratchet to move it to a disengaged position during backfiring of the engine.

Abstract: In electrochemical flow through sensors comprising at least one cell for the passage of a fluid for analysis therethrough, the method of optimizing the flow pattern and signal-to-noise ratio comprising the steps of loading the cell under high pressure with a first fluid which will set to a solid material; before the solid material solidifies, causing a second fluid immiscible with the first fluid to flow through the cell at low pressure to find the optimum flow path therethrough; and, with the immiscible fluid in the cell, allowing the first fluid to solidify. Bandspreading is improved because any offset, junctions, or potential traps that would induce drag or trapping effects on a test fluid flowing through the cell are reduced in size and/or number and/or eliminated. The signal-to-noise is improved as the result of filling spaces in the cell that may contribute to noise but do not contribute significantly to useful signal because of their location relative to the optimum flow path.

Abstract: So that a wing (6) of a window or door, at least rotatable, but preferably rotatable and tiltable, can be made more "sluggish" during rotation, a braking device is inserted between the fixed frame (1) and the wing (6). It consists essentially of a basic part (2, 3) and of a wing part (4, 5), the latter being fastened to the wing and the former to the fixed frame (1). A braking device, whose effect can be varied and therefore adjusted by means of a tension device (27, 28), especially with brake discs (25, 26, 32, 34, 38), improves the braking effect. So that the wing can also be tilted in spite of this braking device and to ensure that no special measures or actions are needed for this, there is a plug connection which consists of a peg (8, 11) of the part fastened to one frame and of a receptacle (9, 10), interacting therewith, of the part to be fastened to the other frame. <IMAGE>
