Title: Filling valve for drawing off liquids
Inventor: KNABE UWE
IPC: B67C3/28
Filed: 1981-04-22
Abstract: To ensure that vessels are not filled to different levels, the closing process of filling valves which are arranged on a rotating filling machine is to be completed independently of the valve involved as soon as the prescribed filling level of the container in question has been reached. To achieve this, it is proposed according to the invention that an actuating device be preferably arranged in the lower region of the valve gate, close the latter when the prescribed filling level has been reached and be operatively connected to a checking device which determines the filling level.

Patent DE-3125793-A1 (DE)
Title: Keyboard coding device
Inventor: TELLERMAN JACOB
IPC: H03M11/00
Filed: 1981-06-30
Abstract: An ultrasonic waveguide (5) is used for coding magnetic keys (1 to 4) on a keyboard. The magnets (1, 2a, 3a, 4a and so forth) of the keys act with their respective magnetic fields on the ultrasonic waveguide (5) which makes it possible to generate signals in a given time relation to an applied pulse which provides for coding by means of depressed keys. Since the required information essentially appears on a wire, particularly a single wire, the system is fundamentally a very reliable solid-state system in which the entire basic-signal processing takes place in an "integral" ultrasonic waveguide component. Potential simplicity, construction at low cost and the very high reliability have the effect that the invention can be very suitably and advantageously used in keyboards for computers, data processing systems or equipment, teletype systems or equipment, computer user (home) terminals or time-sharing stations, computer-controlled booking stations, visual display consoles or desks etc. <IMAGE>

Title: Directional coupler for optical signals which serves as a switch
Inventor: WIEDEBURG KLAUS DR ING
IPC: G02F1/313
Filed: 1982-01-29
Abstract: Directional coupler for optical signals which serves as a switch and uses integrated circuit technology, two closely adjacent light guides (A-A', B-B') which are arranged in parallel along a coupling section being mounted on a substrate, e.g. of LiNbO3 by means of Ti doping, and there being mounted on the light guides along the coupling section electrically conductive electrodes (E11 ... E16, E21 ... E26) which are electrically controllable in each case and, depending on the electrical control voltage (V1, V2) between the electrodes, directly (from A to A') relay the light guided in the relevant light guide (A-A') or relay it in an interchanged fashion (from A to B') crosswise between the light guides. The level of the control voltage can be reduced by mounting more than two electrodes (E11 ... E16) on one of the two light guides (A-A') along the coupling section - preferably even on both light guides (A-A', B-B') along the coupling section. <IMAGE>
Patent DE-3212286-A1 (DE)
Title: Lockable hydro-pneumatic suspension for axles with different loads
Inventor: PEIFFER JOACHIM DIPL ING
IPC: B60G17/005
Filed: 1982-04-02
Abstract: The invention relates to a lockable hydro-pneumatic suspension. Lockable suspensions are required, for example, for the front axles of wheel loaders, which are to be sprung for road travel with different loads, but are to be connected as rigidly as possible to the frame in certain working conditions. Known locking mechanisms bring about a draining of the spring cylinder and mechanical locking after lowering onto the compression stops or a separation of the hydraulic accumulator from the then locked double-acting cylinders. Others produce running out of the spring cylinders onto the rebound stops. There are difficulties with all these methods if load changes have occurred between locking and unlocking. This is prevented according to the invention in that, by partially draining the hydraulic accumulator and piston chambers and at the same time pressurising the annular chambers, lowering to the compression stops and locking occurs, the pressure in the hydraulic accumulators being discharged by a pressure retaining valve only down to a pressure lying somewhat below the minimum pressure. A special valve ensures that the normal levelling is damped but that large flow cross-sections are available if needed. The invention is intended to be used preferably on wheel loaders, which work without suspension, but can be operated in road traffic and in load and carry operation with adequate comfort and higher speeds of travel.

Patent DE-3235709-A1 (DE)
Title: Aquarium installation
Inventor: KOERPER HANS DIPL KFM
IPC: A01K63/04
Filed: 1982-09-27
Abstract: An aquarium is described, having an aeration installation, which operates particularly effectively and at a high degree of efficiency and by means of which, at the same time, good and thorough mixing of the water can be achieved. To this end, water is pumped out of the tank and passed back through jets onto the surface of the water. As a result, the water is able to absorb substantially more atmospheric oxygen than with conventional aquarium aerators, which operate in accordance with the principle of the passing-through of air. In a preferred example of embodiment, jets are arranged on two opposite sides of the aquarium tank and are acted upon alternately. As a result, a surf-like reversing flow arises in the tank, which is particularly advantageous for seawater aquaria.

Title: System for arranging packages in a row at predetermined intervals
Inventor: HOMANN ERWIN
IPC: B65G47/08
Filed: 1982-12-28
Abstract: The invention devises a system for arranging packages in a row at predetermined intervals. This row of packages is intended to be combined with other rows to form layers, which can in their turn be palletized. Under the system provided for by the invention, the packages which reach the grouping/conveying section can be held at appropriate intervals by means of a light barrier (11), two groups of counters (201-20k-1/222-22k) and space distributors which are controlled by this circuit. In this process, the first group of counters records the passage of a certain package and emits a triggering signal to a counter (22 mu ), which is incremented by means of pulses from a pulse generator (14). The pulse generator (14) is synchronised with the grouping/conveying section, so that the counting corresponds to the path of the package in question along the grouping/conveying section. The counter emits a signal when a number has been reached which indicates that the package has completed its passage to the space distributor, which is to halt the following package. This signal raises the space distributor (7 mu ). <IMAGE>
