Abstract: A method and a device is indicated for removing grid debris (10) on a grid (6) which is partially immersed into a waste water flow and inclined in the flow direction, which grid possesses, if appropriate, an adjoining grid apron (33), the grid debris (10) being guided by means of a raking device (20, 21, 22) which engages between the bars of the grid (6) in a periodical engagement movement, towards a discharge point located at the upper edge of the grid (6) or the grid apron (33). The characterising aspect of the invention is seen in that the grid debris (10) is removed by means of the successive transfer from mutually adjoining removal sections simultaneously to at least two removal sections. The preferred constructional solution consists in providing at least two rake parts (21, 22; 30, 35, 36, 37, 38) which execute, simultaneously, translatory movements in the same direction, which rake parts are arranged at a distance in the removal direction and are connected to each other with a common movement- actuating mechanism. …<IMAGE>…

Abstract: The invention relates to a circuit arrangement for detecting voltages from various voltage ranges supplied to a circuit input, which contains at least one differential amplifier one input of which is coupled to the circuit input and the other input of which is connected to a reference voltage. Due to the fact that a semiconductor arrangement, the conductivity of the main current path of which can be controlled by a control voltage applied between its control electrode and a connection of the main current path, is connected with this connection to the circuit input and is connected with its control electrode to a supply voltage connection of the circuit, in such a manner that the semiconductor arrangement changes its state of conductivity when the potential at the circuit input exceeds the potential at the supply voltage connection connected to the control electrode, the circuit manages with a particularly low supply voltage. <IMAGE>

Abstract: A method of specifying the operands for a microcoded CPU employs a combination of a set of microinstruction routines for generic operand modes, along with hardware primitives for selecting various specific types of operand treatment. Decode of a machine-level instruction produces an entry point for the microstore to select one of the set of generic operand modes, and also decode of the instruction produces control bits that are used directly to select the specific operand type or use by the hardware primitives. In this way, branching is avoided in the microinstruction sequences for operand specifying, but yet the amount of microcode needed is a minimum.

Abstract: Die Erfindung betrifft eine Halbleiteranordnung, die insbesondere bei der Herstellung infrarot-emittierender Dioden Verwendung findet. Auf ein n-dotiertes GaAs-Halbleitersubstrat ist eine erste Si-dotierte GaAlAs-Schicht aufgewachsen, die eine n-leitende Zone und eine p-leitende Zone enthält. Der Al-Gehalt nimmt im Verlauf der Schicht kontinuierlich ab. Auf die p-leitende Zone der ersten GaAlAs-Schicht ist eine zweite GaAlAs-Schicht aufgewachsen. Die Al-Konzentration an der Grenzfläche zur darunterliegenden Schicht ist größer als die Al-Konzentration der ersten GaAlAs-Schicht an der Grenzfläche zum Substrat und nimmt kontinuierlich mit der Dicke der Schicht ab. Durch den Verlauf der Al-Konzentrationen in den beiden epitaktischen Schichten wird ein Lichtleiteffekt erzielt, so daß die emittierte Strahlung im Gegensatz zu herkömmlichen GaAlAs-Dioden bevorzugt auf den senkrecht zum Substrat orientierten Seitenflächen der Halbleiteranordnung ausgekoppelt werden kann. Durch diese Maßnahme braucht das Halbleitersubstrat bei der Herstellung von infrarot-emittierender Dioden nicht entfernt werden. <IMAGE>

Abstract: A wound evacuator for extracting body fluids from a patient has end walls (20,22) connected by a side wall (24) to form a cavity (26) for receiving the body fluid. Springs (28) within the cavity bias the end walls (20,22) apart, to expand the cavity (26). One of the end walls (20) has an inlet opening (30) including a one-way check valve (32) through which body fluids can be drawn by the partial vacuum created within the expanding cavity (26). An outlet opening (38) in the end wall (20) has a discharge valve assembly (40) with a valve member (46) which is held against a valve seat (44) by the partial vacuum within the cavity (26), and is moved away from the valve seat (44) when the end walls (20,22) are manually pressed together to cause body fluids in the cavity (26) to be discharged through the valve assembly (40) to a collection bag (18). The valve assembly (40) has an end fitting (52) by means of which the collection bag (18) can be connected to the evacuator. The collection bag (18) has an inlet port (70) with an anti-reflex valve (78). The valve member (46) is freely movable within a passageway (50) in the discharge valve assembly (40), so that after fluid has been discharged from the evacuator to the collection bag (18), when the partial vacuum created within the expanding cavity (26) extends to the anti-reflex valve (78) in the collection bag (18), the valve member (46) is positioned in the passageway (50) away from its seat (44). On separation of the collection bag (18) from the evacuator, the partial vacuum within the cavity (26) draws body fluids from the passageway (50) and the bore (38) in the end fitting (52), before the valve member (46) moves into sealing engagement with the valve seat (44). Leakage of body fluids upon separation of the collection bag (18) is thus substantially reduced.

Abstract: A guidance system for a homing missile has an observer filter (41) which utilizes signals representative of range (R), range rate (R), acceleration normal to the line-of-sight of the missile ( yM), optionally acceleration along the line-of-sight of the missile ( XM), and line-of-sight rate of the missile to a target (λM). The observer filter (41) includes means (47, 43, 49), responsive to a lateral acceleration signal ( ÿM), a measured range rate signal (R m ) and a range signal (R) for providing an estimated line-of-sight rate signal (λ̇est). The measured line-of-sight rate signal (λ̇m) and the estimated line-of-sight rate signal (λest) are applied to a subtractor (55) to produce a difference output signal. The difference output signal is applied to a multiplier (57) to produce an error signal which is added (51) to a line-of-sight acceleration signal (λ̇est) to minimize the difference output signal. The estimated line-of-sight rate signal (λ̇est) provides a more accurate estimate of the actual line-of-sight rate of the missile to the target than that which can be obtained with a standard proportional navigation system, and is applied, in combination (59) with the measured range rate signal (Ṙ m )to control an autopilot (23).
