Patent DE-4333263-A1 (DE)
Inventor: BIPPUS HANS-DIETER
IPC: H04Q1/14
Filed: 1993-09-24
Abstract: The invention relates to a terminal block consisting of an insulating material housing (2) and of insulation-piercing terminal contact elements (7), which are arranged in said housing, for incoming and outgoing conductors. In order to simplify the connection of the conductors to the insulation-piercing terminal connecting elements (7) and to enable protection of the cables against overvoltages and overcurrents as well as making it possible to pick off voltages which pass via the terminal block, it is proposed according to the invention that the insulation-piercing terminal contact elements (7) be arranged separately from one another in the insulating material housing (2), and that each insulation-piercing terminal contact element (7) be connected to a centre tap (18) and that the centre taps (18) which are opposite one another spaced apart in the insulating material housing (2) be capable of being electrically connected to one another by means of different function connectors (31, 40, 50). <IMAGE>

Title: Circuit arrangement for the automatic correction of the transfer characteristics of electrodynamic sound transmitters without additional mechanical or acoustic sensor
Inventor: KLIPPEL WOLFGANG DR
IPC: H03H21/00
Filed: 1993-10-06
Abstract: The invention relates to an arrangement for automatic correction of the linear and nonlinear transfer characteristics of electrodynamic sound transmitters (loudspeakers, headphones, actuators, ...). The arrangement consists of an adaptive linear or adaptive nonlinear correction filter (3) which is connected to the electric terminals of the sound transmitter (1) via a detector circuit (2). The detector signal generates from the electric terminal signals a control signal v(t) which approximates the velocity of the voice coil. The output (11) of the detector circuit is connected to the first input (12) of a differential amplifier (13) which compares the control signal v(t) with the reference signal at its other input (14) and provides an error signal at its output (15). According to the invention, the detector circuit is constructed to be adaptive and equipped with an additional control input (17). The output (15) of the differential amplifier is connected both to the control input (16) of the adaptive correction filter and to the control input (17) of the adaptive detector circuit. The arrangement allows an adaptive adaptation of the correction system to the sound transmitter without using any additional mechanical or acoustic sensor. <IMAGE>

Date Jun. 1, 1995A continuous kneading machine for doughs comprises a tub-shaped container, open at the top, which contains at least one pair of identical synchronously counterrotating kneading shafts. A series of U-shaped bracket components are attached to each kneading shaft longitudinally. The U-shaped bracket components are angularly offset relative to each other around the shaft circumference, with each bracket component being inclined in the direction of motion, such that the bracket components form a helical profile along the kneading shaft. A "manual" type of kneading is achieved due to the shearing off, pulling apart, and pressing together actions of the inventive shaft and bracket configuration.

Title: Method for reduction of condensate formation in central heating boilers
Inventor: JANNEMANN THEO DIPL ING
IPC: F24H1/41
Filed: 1994-01-14
Abstract: The method for condensate reduction involves a boiler with a burner and heat exchanger against which the combustion gasses act and through which the heating water is pumped. A surface temperature above dew point is achieved on zones of the heat exchanger away from the burner, by setting the water flow speed to a low value. The temperature is controlled dependant upon boiler water temperature, feed temperature, return temperature, or the surface temperature of the heat exchanger. When water or surface temperatures are low, a smaller speed is set than when the temperature is at a lower level. The pump RPM is controlled or regulated, to adjust the water flow speed. Different pumps are used for higher or lower speeds.

Title: Opto-electronic semiconductor laser appts. for use as semiconductor laser, amplifier, coupler
Inventor: HILLMER HARTMUT
IPC: H01S5/12
Filed: 1994-05-31
Abstract: The appts. includes a laminated structure (1-15) and is organised in three different distributed feedback grating structures (G1-G3). Two of the layers (5,11) are active layers having optical amplifier characteristics and other layers have different refractive indices. Control voltages are applied to change the optical characteristics to tube the device. The initial two gratings (G1,G2) in respective layers (2,14) have a small refractive index and defined thickness and flank the two active layers of a higher refractive index.  Other layers (1,3,13,15) surrounding the two gratings each have lower refractive indices. The two gratings define an over grating in umpteen microns within which lies an inner part in a grating free region with a variable grating period. Within the region, the middle layer (8) has a greater refractive index than its immediate neighbours (7,9) and is deemed to be the third grating (G3) of the two waveguides formed from the two active layers, co-directionally coupled.

Title: Device for illuminating target area of work piece
Inventor: DORSEL ANDREAS DR RER NAT
IPC: B25H1/00
Filed: 1994-10-05
Abstract: The light from a laser diode (1) is collimated by a lens (2) and deflected by a mirror (3) with an aperture to a diffractive optical element (6) or D.O.E. consisting of equidistant circular zones with a saw tooth profile. The D.O.E. is mounted coaxially to the drill axis of a drilling machine (5) which can slide on a mounting stand (4) and produces light with a conical envelope which falls on the surface (7) of the workpiece. The device can be clamped to the drill holder by a simple circular clamp arrangement. When the D.O.E. is illuminated rays are focussed onto the workpiece and are reflected back in the direction of the user's eyes. A cross wire arrangement can be included which would then show up as a target on the surface of the workpiece.

Filed: 1994-11-02
Abstract: The cylindrical container (1) jacket (18,18') consists of prefab reinforced concrete segments (10) with a vertical groove on both front sides, with opposite grooves filled by seal forming material. Several, spaced tensile members (2) inside the segments hold the jacket together, as they pass through the material in the grooves. The tensile members are embedded in the filling material. The jacket lower portion (18) is pressed against a bottom plate (5) by the prestress of the tensile members. Between each two segments is located a lower recess (51), engaged by the on side cast concrete bottom plate and thus positively closes the lower end of the front side segment grooves.

Abstract: Un système de commande et de réglage sert à ajuster le mélange d'air/carburant d'un moteur à combustion interne (12). Le système comprend une sonde à l'oxygène (sonde lambda) (14) exposée aux gaz d'échappement du moteur (12) qui émet un signal de sortie qui représente une mesure du coefficient d'air lambda. Une mémoire de base (10) enregistre des temps de dosage du carburant qui sont utilisés afin de commander au préalable le moteur (12) jusqu'à obtenir un coefficient prédéterminé d'air lambda. Une mémoire (18) de valeurs de consigne enregistre des valeurs de consigne du coefficient d'air et un agencement de réglage (20) corrige les temps de dosage du carburant lus dans la mémoire de base (10) en fonction du signal de sortie mesuré par la sonde lambda (14) et d'une valeur de consigne correspondante lue dans la mémoire (18) de valeurs de consigne. La valeur réciproque du coefficient d'air lambda est enregistrée dans la mémoire (18) de valeurs de consigne. Chaque temps de dosage du carburant lu dans la mémoire de base (10) est lié par multiplication à la valeur réciproque correspondante du coefficient d'air lambda lue dans la mémoire (18) de valeurs de consigne. Un convertisseur (16) convertit en une valeur réciproque correspondante du coefficient d'air lambda le signal de sortie au moyen d'une relation caractéristique de la sonde et connue au moins approximativement entre le signal de sortie de la sonde lambda (14) et le coefficent d'air lambda. La prise en considération de la relation linéaire entre la valeur réciproque du coefficent d'air lambda et la quantité de carburant (temps de dosage du carburant) permet d'obtenir un réglage rapide et précis au moyen d'un agencement linéaire simple de réglage.
