Title: Method and apparatus for the positioning of textile blank pieces
Inventor: KOEHLER EBERHARD PROF DR ING
IPC: A41H43/02
Filed: 1993-09-19
Abstract: Known positioning methods and apparatuses position plane cloth blanks, without securing in position, according to three coordinates by means of air cushions and stops, with adjustment according to size and material, or by means of displaceable depositing plates and actuating drives which are complicated to control, are sluggish and tend to require build up. The new solutions execute, without adjusting work, independently of size an orientation of a blank edge taking place successively in three coordinates and method steps, friction grippers and a vacuum serving for securing the blank piece in position. The essence of the invention according to Figure 1 is that the blank piece (17) deposited on a positioning plate with a suction device is fixed in position alternately by means of suction air and friction grippers and, as a result of movement by means of actuating drives in the x, y and  phi  directions, is moved relative to the punctiform photosensors (1 and 2), fixed to the frame, in three movement steps as far as the sensor (1), is rotated about the latter as far as the sensor (2) and is displaced parallel to the x axis by means of the clip (19) as far as the sensor (1). The sector of use is the automatic processing of blank pieces in the textile industry. <IMAGE>

Title: Method of regulating the pick-up reliability in CD players in motor vehicles
Inventor: KUEHN HANS-ROBERT
IPC: G11B7/09
Filed: 1993-10-15
Abstract: It is known that the drive resonance occurring in the case of CD players is influenced by means of an electromagnetic arrangement, it being possible at the same time for the movement of the drive to be determined. The invention is based on the object of providing a method of improving the pick-up reliability. According to the invention, the automatically occurring interference amplitudes are analysed during operation, counter-measures are computed with the inclusion of known data on the player regarding resonance behaviour on the basis of corresponding algorithms and a control signal is generated, by which the pick-up reliability of the player is improved by means of the electromagnetic arrangement. In particular for CD players in motor vehicles. <IMAGE>

Title: Direct-current lifting magnet (levitating magnet)
Inventor: OESTERLE HANS-PETER
IPC: H01F7/17
Filed: 1993-11-04
Abstract: The direct-current lifting magnet has, within a coil former (10) which is surrounded by a coil (5), a device (2, 4, 6, 9) for holding the armature (3) in the form of a spline, by means of spring force from a compression spring (7), alternately in a first position (A) and in a second position (D) which is axially displaced with respect to the first position (A). When current flows through the coil (5), the armature (3) is in this case moved axially, and such that it is forced to rotate, from the first or second position (A, D) respectively into the second or first position (D, A) respectively. Such an arrangement offers the advantage of the armature (3) being fixed in the first or second position (A, D), respectively without any current flowing and without it being necessary to provide a permanent magnet. <IMAGE>

Patent DE-4417853-A1 (DE)
Title: Pressurised fluid motor or pump unit
Inventor: GRAHL THOMAS
IPC: F04B49/00
Filed: 1994-05-20
Abstract: The motor or pump unit has a housing made in two parts (1,2) held together by screws. It has a facility which receives either transverse forces or displacement in order to generate from it a signal proportional to the torque. The registering of the transverse forces or deformations is integrated into a torque limiting mechanism. The shaft of the unit is designed so that the largest possible deformation is achieved to maximise the signal deviation. The registering of the shaft sag takes place by a nozzle-flapper system acting with the cylinder block.

Title: Prevention of unwanted crystal growth in gas scrubbing suspensions
Inventor: PLASCHNA HARALD DIPL ING
IPC: B01D53/50
Filed: 1994-05-20
Abstract: To prevent unwanted crystallisation of solids in suspensions used for exhaust gas scrubbing, the water containing sulphate and pref. reaction products (1) in a watery form with a sulphate content are diverted from the desulphurising assembly (8) for the exhaust gas into a container (2). In the container, it is treated with a part flow of fresh calcium hydrate suspension (5) for a sufficient reaction time for sulphate precipitation. At the station (4) to quench the quicklime, water (3) with a low sulphate content is added to give a fine grain calcium hydrate suspension with insignificant grit formation.

Title: Recording and projection device for a cine film
Inventor: NAKATSUYAMA TAKASHI
IPC: G03B21/44
Filed: 1994-06-21
Abstract: A recording device for a cine fim and a device for projecting a cine film (100) are provided which develop little noise due to the film advance. A cine film (100) is advanced on an image base, with the result that the film is advanced when it is clamped in between a drag roller (45) and a rotating roller (48) and such that the film advance is stopped when an oscillation coil (moving coil) (43) is driven to move the drag roller (45) away from the rotation roller (48). A recording unit (30) records an image of the cine film each time the film advance is stopped. In this way, recording can be carried out with extremely little noise developing due to the film advance. The same kind of film advance is carried out during the projection of each image, and each image is likewise projected by a projection unit (70) each time the film advance is stopped. Thus, a projection can likewise be carried out with extremely little noise developing due to the film advance. <IMAGE>

Title: Measuring concentration of solid particles in gas esp. for controlling administration of coal dust in coal-powered power station
IPC: F23N5/18
Filed: 1994-07-25
Abstract: The measurement method involves multiple measuring units (14), each of which includes a transmitter (20) using a Gunn-oscillator (22) to transmit electromagnetic waves (29), and a receiver which uses a Schottky diode (23). The transmitter and receiver are connected to a sensor tube (18) which the gas (X) to be analysed flows through. They are connected by an angle frame (25.1, 25.2), a connecting plate (26.1, 26.2) and an antenna (24.1, 24.2). The electromagnetic waves (29) travel through the tube, reflecting at a specified angle. In this process, some absorption by the solids takes place, which is measured, giving the amount of solids in the gas.

Inventor: BEYER LUTZ
IPC: B28B13/02
Filed: 1989-12-14
Abstract: Un dispositif sert à commander dans le temps la pression de remplissage d'un outil (11) de moulage par compression avec une masse pâteuse ou épaisse, notamment lors de la fabrication d'aimants à oxyde. Un capteur de mesure (14) détecte la pression dans l'outil (11) de moulage par compression et applique un signal de pression correspondant à un premier étage (19) de valeur limite et à un deuxième étage de valeur limite (21) par l'intermédiaire d'un discriminateur. Les sorties des deux étages de valeur limite (19, 21) sont connectées à une porte de circuit logique (22) qui génère un signal de déclenchement d'un synchroniseur (23) qui lui est connecté lorsque le signal du capteur dépasse une première valeur limite du premier étage (19) de valeur limite en même temps qu'il tombe au-dessous d'une deuxième valeur limite du deuxième étage de valeur limite (21). Le temps de maintien du synchroniseur détermine la pression de remplissage. On peut ainsi déterminer à l'avance la pression de remplissage optimale grâce à une détection précise du moment où la pression de remplissage voulue est atteinte, ce qui permet d'obtenir des cycles de travail de courte durée, une façon simple de prédéterminer la pression et une réduction sensible des pièces manquées.
