Patent EP-0413960-A1 (EP)
Inventor: SPALT WOLFGANG DIPL-ING FH
IPC: F15B13/00
Filed: 1990-07-18
Abstract: In a solenoid valve, valve bodies (12) are arranged on a base plate (10). So that the electrical leads (35) for the electromagnetic adjusting units (19, 20) can be run from one side of the valve body (12) to the other when there is only one electrical connection block (32), an intermediate plate (11) is arranged between the base plate (10) and the valve body (12). The intermediate plate (11) has elastic intermediate parts (25) which, through their zigzag-shaped design, enable the tolerances to be compensated even in the case of rigid plastic. But if the intermediate part (25) is made of a material having a high modulus of elasticity, different valve bodies can also be mounted on the base plate (10). The solenoid valve is consequently of simple construction and can be produced in a modular construction system. <IMAGE>

Abstract: A confocal scanning ophthalmoscope consists of an upper instrument part (26) which can be aligned onto the patient's eye, and of a supply block (27). The supply block (27) contains one or more lasers (9) for generating the measuring light, and a secondary electron multiplier (25) for detecting the light backscattered on the fundus of the patient's eye. 
<??>Provided between the supply block (27) and the upper instrument part (26) are two flexible optical fibres (7, 8); a first (7), which conducts the light of the laser (9) to the upper instrument part (26), and a second (8), which conducts the light backscattered on the fundus of the eye to the secondary electron multiplier (25). 
<??>Owing to the spatial separation of the lasers (9) and the secondary electron multiplier (25) from the upper instrument part (26), the latter is especially compact and can therefore easily be aligned onto the patient's eye. Moreover, electromagnetic stray fields occurring at the galvanoscanner (18) are prevented from being coupled into the data lines downstream of the secondary electron multiplier (25).

Abstract: A bioassay technique employing aquatic amphipods sensitive to water borne toxic materials is employed for routine screening of toxicity levels in dilute solutions. For example, a number of  Hyalella azteca  are counted into a sample of water to be assayed. Similar numbers are counted into volumes of toxicant-free water as a control. Every twenty four hours the number of surviving organisms is counted. The mortality thus determined is compared with the mortality of the same strain of anthropods in solutions with known amounts of toxic materials.

Abstract: Adaptive discrete-time filters, as used, for example, in echo cancellers, comprise a control circuit for controlling the coefficients for adjusting the discrete-time transversal filter. A prior art manner of adjustment is the LMS algorithm. This algorithm is relatively simple because few computations are necessary but they may lead to poor convergence results with autocorrelated input signals. Further, the OP algorithm is known which leads to good convergence results with auto-correlated input signals but which also requires a substantial amount of computation. According to the invention an algorithm is provided for input signals, more specifically speech signals, which may be modelled with an autoregressive process of the order of p, which algorithm requires the same amount of computation as the LMS algorithm but leads to the same or better convergence results for this type of signals than the OP algorithm.

Abstract: A paint spraybooth has a generally horizontal partition (18) which defines a lower boundary of the work station and a discharge structure (22) depending from the partition. Means (33) are provided for supplying a flow of liquid into the discharge structure and for supplying a flow of air carrying the particulate from the work station into and through the discharge structure. A scrubber chamber (20) is also provided into which the discharge structure projects, the chamber including a receptacle (24) for containing a pool of liquid. The discharge structure itself is constructed to include an elongated inlet channel (40) and a plurality of discrete discharge tubes (50) extending down into the scrubber chamber. The inlet channel has a top (42), a bottom (44) and a pair of converging sidewalls (46) which depend from the partition (18) at the top of the channel. Each of the discharge tubes (50) has sidewalls (52) and endwalls (56) extending down from the bottom of the channel and together forming a discharge port (60) which is directed at the receptacle within the scrubber chamber. The sidewalls (46) of the inlet channel (40) and the sidewalls (52) of each of the discharge tubes (50) join together or merge to form a generally unobstructed surface, permitting unimpeded flow of the water from the application chamber into the receptacle of the scrubber chamber.

Abstract: A strap (10) carries a key (12), and is used to secure the key to part of a user's body such as a wrist. The key (12) has a shank (52) and a head (50) with a slot (54) through which the strap passes. The key head is slidable but captive on a portion (10a) of the strap between a thickened portion (34) and a stop (56). The thickened portion (34) is formed with a recess (36) for receiving a shank when the strap is worn. When the strap is worn, for example on the user's wrist, the head of the key is located between the strap and the user's wrist, whereby the shank of the key is retained in the recess and is shielded to prevent it from causing damage or injury. The side walls of the recess (36) diverge away from the entrance (38) to maintain the strap's flexibility when the key is in the recess.

Abstract: A vehicle brake warning device for use in a vehicle (5) with a brake pedal (51) includes an inertial transducer (1, 6) which produces different electrical signals in response to the magnitude of inertial force experienced during braking, a control circuitry (4, 4') receiving electrical signals from the inertial transducer (1, 6) and having an output dependent upon the received signal, and a warning device (3) activated by the output of the control circuitry (4, 4'). Whenever the brake pedal (51) is actuated to reduce the speed of the vehicle (5), the inertial transducer (1, 6) experiences an inertial force whose magnitude depends upon the speed of the vehicle (5). The inertial transducer (1, 6) sends out an appropriate signal to the control circuitry (4, 4'), which signal corresponds to and is dependent upon the magnitude of the inertial force. The control circuitry (4, 4') activates the warning device (3) to send out a warning signal which varies depending upon the magnitude of the inertial force.
