Patent DE-3733983-A1 (DE)
Title: Method for damping interfering (wind) noise in sound signals transmitted by hearing aids
Inventor: MAAS RAINER
IPC: H04R25/00
Filed: 1987-10-08
Abstract: A method is proposed for damping interfering noise in the sound signal in the case of transmission by hearing aids. In this case, the sound signals detected are digitised, and the spectral distributions are determined by Fourier analysis. The temporal variations in the spectral distributions are monitored in a plurality of frequency windows. The respective temporal variations are compared with prescribed and, as the case may be, modified limit values. Depending on the comparison, control signals are produced which vary the amplitude of the spectral distributions and/or the cut-off frequencies in the respective frequency windows in such a way that the interference signals are suppressed. The changed spectral distributions are subsequently converted into synthetic sound signals which, for their part, are converted into acoustic signals. <IMAGE>

Title: Connecting element for connecting and stabilising a bone in the region of a fracture
Inventor: FISCHER ARTUR PROF DR
IPC: A61B17/80
Filed: 1988-03-17
Abstract: Connection of the bone areas adjoining a fracture is effected using rigid steel elements which are implanted with additional fastening elements. Such rigid connections are not expedient in rib fractures because these require slight elasticity in the region of the connection. There is proposed a thin-walled connecting element in the form of a metal strip from which comb-like webs project on either side of its longitudinal axis, the webs extending in circular arc shape in cross-section. The connecting element can be clamped in the region of the fracture by bending the ends of the webs.

Abstract: This casing made of unreinforced cellulose has a cross-section with differing wall thicknesses. The section having the minimum wall thickness is opposite the section having maximum wall thickness and is in the section having the larger, outer radius of curvature. The thickness of the section having the maximum wall thickness is in the range of 50 to 160 micrometres, that of the minimum wall thickness is in the range of 10 to 50 micrometres. The maximum of the wall thickness is greater than the minimum of the wall thickness by 50 to 800%. On account of the relationships of its wall thicknesses, the casing shows improved physical properties which are particularly of importance for its use as a synthetic casing for sausages.

Patent DE-3828886-A1 (DE)
Title: Device having a superlattice structure
Inventor: KIMURA MIKIHIRO
IPC: H01L29/73
Filed: 1988-08-25
Abstract: A device having a superlattice structure contains a first composite semiconductor superlattice (RA) of a first conductivity type and a second composite semiconductor superlattice (RB) of a second conductivity type which differs from the first conductivity type. The superlattices are in contact with one another and form a potential barrier between themselves. Each superlattice (RA, RB) contains a multiplicity of alternating quantum well layers (3,5) and quantum barrier layers (4, 6) which respectively have a thickness which is equal to or less than that of the de Broglie wavelength ( lambda ) of tunnelling charge carriers in the first and second superlattices (RA, RB). The potential barrier is situated virtually parallel to the planes of the quantum well layers and the quantum barrier layers. Because of the restricted thickness of these layers (4 to 6), charge carriers can tunnel quickly from quantum well to quantum well through the quantum barrier layers situated therebetween, specifically with a high probability and low loss. An additional superlattice or a doped semiconductor body can be connected to the two superlattices in order to form a bipolar transistor. <IMAGE>

Title: Switching mechanism for line protection circuit breakers
Inventor: MUELLER GERRIET
IPC: H01H73/04
Filed: 1988-10-15
Abstract: More stringent requirements for line protection circuit breakers force the manufacturers to consider how the contact mass of the contact pieces can be reduced. The invention indicates a switching mechanism for line protection circuit breakers, in the case of which switching mechanism the moving contact piece 4 is used in a simplified configuration, without contact limbs. In consequence, the contact behaviour with respect to speeding it up is improved. Such a switching mechanism is used in all line protection circuit breakers and residual current device/line protection circuit breaker combinations. <IMAGE>
Patent DE-3840568-A1 (DE)
Inventor: WULFF MICHAEL
IPC: G03B27/68
Filed: 1988-12-01
Abstract: The copying device for the modification (distortion) of film patterns, which are arranged on a film to be exposed, comprises a light source 2 which is movable over the film and film pattern. A relative movement between the film pattern and the film is effected in a known manner in the axial direction of the movement of the light source in order to carry out the desired elongation or compression. Further, a slit or line diaphragm is provided, preferably in the form of a collecting lens 6, which extends transversely relative to the movement direction of the light source and is movable along with this. According to the invention, the light source 2 is substantially enclosed by a light collecting foil 3 (as is commercially available under the trademark "LISA" of the firm BAYER AG), one edge of the foil extends parallel to the line diaphragm 6 and is adjacent to it. Accordingly, a point light is radiated in spite of excitation by means of a scattered light in the edge axis. Due to the high efficiency, the collecting lens can be sharply stopped down, i.e. a very narrow light slit is usable, so that a great depth of focus is formed and a shadow-draw effect is prevented.
Patent DE-3840892-A1 (DE)
Inventor: BENCKERT HARTMUT DR
IPC: F04B7/02
Filed: 1988-12-05
Abstract: The invention concerns a sequence-control unit for a twin-cylinder thick matter pump with two delivery cylinders (1, 1') discharging through front-located openings (2, 2') into a hopper, and a hydraulically operated pipe switch (3) which is located inside the hopper and can be connected on the input side to each of the openings (2, 2') of the delivery cylinders (1, 1') in turn, leaving the other opening free, and which can be connected on the output side to a delivery line (4). The delivery cylinders (1, 1') are connected to hydraulic drive cylinders (5, 5') which are operated in a push-pull mode by at least one hydraulic reversing-pump (6). At the end of each delivery-cylinder compression stroke, a pipe-switch changeover operation is initiated and during the changeover operation the delivery of thick matter is interrupted. During the pipe-switch changeover operation, the reversing-pump delivery direction is initially kept unchanged, maintaining a free supply of hydraulic fluid to the drive cylinders (5, 5'), and it is not until completion of the pipe-switch changeover operation that the delivery direction is reversed. To initiate the reversal process, a hydraulic or electrical end-limit signal (y, y, 26, 26') is detected at the pipe-switch (3) or at its hydraulic actuating elements (21, 21') after each switchover operation.

Title: Tripping device for switching devices (switchgear) and switching installations in the medium-voltage range
Inventor: DEHARDE HORST
IPC: H01H71/20
Filed: 1988-12-22
Abstract: Live components in switching devices and switching installations can carry overcurrents for a relatively long time. The heating of the components associated with this can destroy insulating encapsulations. This is particularly true in the case of current-limiting components, such as high-voltage, high-rupture capacity fuses, which are used for short-circuit protection in conjunction with high-voltage, high-rupture capacity lower parts, interrupter circuit breakers and load interruption circuit breakers. It thus makes sense to provide additional disconnection protection in special cases. The invention indicates a tripping device for switching devices and switching installations in the medium-voltage range, in the case of which device a fuse body 1 is used on a component 3 to be monitored. An insulating rod 4 which is directly connected to a switching device 6 or to a switching installation, is introduced into the fuse body 1. In the event of an increase in temperature, a switch (circuit breaker) which is connected upstream of the component 3 to be monitored and is inside the switching device 6 or the switching installation is switched off (disconnected). Such tripping devices can be used in switching devices and switching installations in the medium-voltage range. <IMAGE>
Patent DE-3901852-A1 (DE)
Inventor: PALUSCHKA HANS
IPC: H01H73/04
Filed: 1989-01-23
Abstract: In known contact systems for current-limiting circuit breakers, with two moving switching arms in each case per phase, the lower switching arm is connected to the current path by means of a braided cable and, in the event of a short-circuit, pivots against the movement direction of the upper switching arm, which is coupled to the latching mechanism. As a result of the dynamic deflection of the two switching arms in the event of a short-circuit, the arc between the contact pieces is admittedly additionally extended and extinguished more quickly, but the braided cable for the current supply just forms a weak point on the lower switching arm to the extent that the welded attachment of the braided cable to the switching arm is mechanically very highly loaded by the impact-like deflection in the event of a short-circuit. The braided cable can be dispensed with in that the second moving switching arm (3) is held by means of journals (8), directed coaxially to the side, in open, approximately half- cylindrical bearing recesses (9) in pivotably sprung contact on the underside (10) of the current path (6). The moving switching arm (3) additionally has stop tabs (20), which are offset in a parallel manner with respect to the free end of the current path (6), opposite the journals (8), which stop tabs (20) rest on the upper side of the current path (6) when the switching arm (3) is in the switched-on position and secure the spring-loaded switching arm (3) together with the journals (8) on the current path (6) in its switched-on position.   <IMAGE>

Title: Method for synchronously driving pulse-controlled invertors
Inventor: HOFMANN WILFRIED DR ING
IPC: H02M1/08
Filed: 1989-05-06
Abstract: The invention describes a method for obtaining synchronous pulse patterns for driving pulse-controlled invertors, especially for supplying three-phase machines which are operated at a low pulse frequency. The principle is a method in which, starting from a discrete control voltage vector, decomposition into edge vectors and zero vectors is carried out (triple method) by projection with respect to the two adjacent edge vectors which are offset by 60@ respectively. It is proposed to detect the control voltage vector which leads by half the triple range at specific detection times and to convert it into corresponding invertor switching states, via the triple range, in accordance with the pattern according to the invention.
