Patent DE-19529362-A1 (DE)
Title: Fluid loss determination method in hydraulic circuit - building up and leaking adjustable operational pressure in circuit which affects pressure monitor detecting drop in pressure
Inventor: UHRIG WOLFGANG
IPC: G01M3/28
Filed: 1995-08-10
Abstract: The method involves building up an adjustable operational pressure in a circulation, e.g. by a pump and valve arranged in the circuit, which is connected to one or several consumers. The operational pressure in the entire hydraulic circuit or in individual branch lines of the hydraulic circuit is leaked during a selectable unit of time. The leakage affects the operating pressure of a pressure monitor (15) which detects the drop in pressure.

Patent DE-19536752-A1 (DE)
Inventor: WIERES LUDWIG
IPC: B01J35/04
Filed: 1995-10-02
Abstract: The present invention concerns methods and devices for producing a honeycombed body from at least one metal foil (1) composed of at least two different layers, in particular steel roll-bonded with aluminum. The metal foil (1) is provided at least partially by shaping with a structure and is then layered or wound to form the honeycombed body, the metal foil (1), before shaping, being heat-treated by the ohmic heat generated therein. Heating is preferably brought about by induction coils (6). Cold formability is thereby increased and, if necessary, an oxide layer can be provided in a specific atmosphere (10). The invention reduces expenditure in terms of energy and apparatus and enables high-grade honeycombed bodies to be produced economically, in particular with efficiency-increasing microstructures.

Title: Corner loudspeaker horn for radiating music signals in bass range
Inventor: NICKEL FRANK DIPL ING
IPC: H04R1/02
Filed: 1995-10-09
Abstract: The horn emits audio (music) signals in the bass range.

The horn preferably emits extremely low pass signals e.g. music signals with frequencies between 20 and 25 Hz. The horn has a high efficiency so that unusually high sound levels can be reproduced even in higher frequency ranges. The horn is preferably very compact, with a space requirement of about 0.42 sq. metres. The horn can be combined with other horns for different arrangements.

Patent DE-19540795-A1 (DE)
Title: Speaker location method using microphone array
Inventor: ZELINSKI RAINER DR ING
IPC: H03H11/36
Filed: 1995-11-02
Abstract: The method involves using the microphone array for the speaker location, such that all the microphone signals of the array are simultaneously evaluated.  The speech region is divided into numerous, finite sectors, and the correct sector is selected according to the plausibility criteria.  The individual microphone signals, connected for their transit time and phase values, are tested against each other for the phase position coherence, prior to forming the array summation signal.  Then the sector with maximum coherence is selected.  Preferably during this test, varying frequency band decisions are taken, also according to the maximum coherence.

IPC: G11B7/26
Filed: 1995-11-16
Abstract: The device aligns a stack of circular discs (1) of storage media, e.g. CD, CD-ROM, and holds them precisely between two guide plates for machining of the external profile (4) by a cutting or milling tool. The alignment is achieved by three transparent marks on the discs which are illuminated by light beams from below.  The machining tool may be a numerically controlled contour milling tool with hard metal tip, or it may be laser cutter, with suction and cooling devices to remove swarf and keep the discs cool. Any desire shape (6) can be machined by use of a computer programme, provided that two points on the original circumference remain as locations for the CD player.

Abstract: A servicing trolley (11A,11B) on a multiposition textile machine is connected to individual positions to control and monitor the service work being carried out at that position. The machine has a terminal (T) which is connected to the data transmission network (18) to scan and indicate central or distributed data on production and faults requiring service on individual positions.  An additional terminal (t) with an input unit (y) and an output unit (x) is fitted to the servicing trolley (11A,11B).  The input unit (y) is specially arranged for queries on the state of individual positions (4,4t). The output unit (x) is specially arranged to show faults self-diagnosed by the machine and their causes.  When the servicing trolley (11A,11B) is at a working position (4p,4s) it is connected to the data transmission network (18) of the machine.  Preferably when the trolley (11A,11B) stops at a position the terminal (t) is connected to the network (18) so that the situation at any position can be interrogated independently of the current trolley position or the service operation which is being carried out.  Switch arrangements are provided for an operator to call the servicing trolley to a particular position which has been signalled as having a fault which the service trolley was not able to repair.  The operator can then observe the operation to diagnose the cause of the fault.
