Title: Airbag system for upper dashboard mounting
Inventor: TAGUCHI MASAHIRO
IPC: B60R21/261
Filed: 1995-04-03
Abstract: The system (50) has an inflating device (3) which generates gas to inflate an airbag (2). The bag shape is formed by two-dimensional stitching on the edge of at least one piece of bag fabric.

Title: Warhead for combating seas mines
Inventor: SCHILDKNECHT MANFRED DR
IPC: F42B33/06
Filed: 1995-06-01
Abstract: Sea mines are countered by a warhead with two shaped charges (24) in a housing (12), detonated by a firing device (20) in a direction determined by the shape of the end faces (20) of the charges, producing a cone-shaped region (42) of high pressure from the two interpenetrating shock waves (40). The faces of the two charges are pref. convex or concave in shape in a first plane and are convex in a plane perpendicular to the first plane, being symmetrically formed about a plane of symmetry (36). The faces pref. define a space (30) which is filled with a medium (32) which has a shock wave impedance corresp. to that of water.
Patent DE-19520353-A1 (DE)
Inventor: MUSCHALLIK CLAUS DIPL ING
IPC: H04L27/26
Filed: 1995-06-07
Abstract: In the OFDM methods, a plurality of modulated carriers are transmitted by frequency multiplexing, which results in an almost rectangular spectrum owing to the high number of carriers. In order to separate the carriers from one another again in the receiver, a fast Fourier transform is carried out such that each carrier can be cleanly separated from the others when the carriers are exactly orthogonal relative to one another. However, the orthogonality of the carriers can be disturbed by various causes. Furthermore, in the receiver the useful signal has to be separated from the undesired neighbouring channel signals by analog or digital filtration. In order to improve carrier and channel separation, the selectivity of FFT filtration can be increased by increasing the number of FFT components. However, this normally leads to an undesirably high increase in computing steps. The claimed configuration of the time window used within the context of the FTT and oversampling before the FFT render the calculation of some of the coefficients superfluous.

Title: Machining method, especially for reaming
Inventor: OSTERTAG ALFRED
IPC: B24B39/02
Filed: 1995-06-14
Abstract: The method involves a tool (3) attached to the end of a coolant fluid delivery tube (2). The tool machines the inner wall (14) of the cylinder (6) whilst coolant is supplied into the space between the wall and the tool through openings (15, 16) in the tube. The cylinder may be rotated with respect to the tool and delivery tube. The coolant flows from the delivery tube on the opposite side of the tool from its head. It continues past the tool head carrying any debris away from the machining head.

Title: Displacement pump with axially reciprocated and rotated piston - uses convex or concave control pocket base larger in radius than piston using grooved piston to connect cylinder entry and exit per cycle
Inventor: WEISBRODT RAINER
IPC: F04B7/06
Filed: 1995-08-04
Abstract: The base (12) of the control pocket (9) should be convex and is made up of a cylindrical surface which is of larger radius than the piston (3), or made up of two abutted flat surfaces. In a case in which the base is concave, this is formed by a single cylindrical surface and extends over this surface by an angle beta less than 90[deg], this same radius being that of the piston (3) and at an angle to the piston axis. The cylinder (2) has opposing entries (16,17) for the flushing agent infeed and exit respectively, using an annular piston groove (18) to connect the two entries temporarily in each working cycle. The cylinder can move axially in relation to the piston dead-end points. The cylinder moves in the main housing (1) in the axial direction so as to initiate the flushing action, using the piston groove (18) to establish the connection link (16,17) over the required period. The control pocket (9) is used to connect the piston space (11) alternatively to the vacuum and pressure connections (6,8). The piston is a sintered component and the pocket is simply ground into shape, (15) denoting the overall flushing device.

IPC: G05F3/24
Filed: 1995-08-18
Abstract: The load (1) supplying constant current circuit comprises current source (10) supplying temp. dependent input current of preset value to a reference transistor (20), which generates a reference voltage (Vr) at one junction point coupling it to the current source. A voltage divider (30) generates a control voltage (Vc) by dividing the reference voltage.

The temp. dependence of the output current is adjustable by setting the voltage divider ratio of the voltage divider.
Patent DE-19532343-A1 (DE)
Title: Semiconductor device mfr. for microwave communication
Inventor: MATSUOKA HIROSHI
IPC: H01L21/76
Filed: 1995-09-01
Abstract: The method involves using a substrate (101) with opposite front and rear surfaces and active elements (102-104) formed on the front surface. Concave parts are also formed on the front surface in which a photoresist is then deposited until it fills the concave parts and covers the entire substrate surface.  The photoresist is then exposed and developed, using a marker with such apertures that the photoresists remains in the concave parts. The photoresist is reshaped by annealing to smooth the front surface. Plating electrodes and wires are then formed on the substrate, and the photoresist is finally removed from the concave parts.

Title: Loudspeaker crossover method for dividing signal into frequency bands
Inventor: RICHT STEFAN DIPL ING
IPC: H04R3/14
Filed: 1995-09-14
Abstract: The original signal (1) is filtered in an electrical high-pass filter (2) and this forms with a delay unit (4) the high-pass channel, giving an output signal (5) with a negative sign to the adding point (12). Also the undelayed (3) and also the delayed high-pass signal (5) serve to control a tweeter or another filter.  An equaliser circuit (7) or (8) is added to improve the characteristics of any loudspeaker, while the low-pass channel is formed by the additional low-pass filter (6) and the equaliser circuit (9) to correct undesirable characteristics.

Title: Ink storage pen for ink jet printing head, ink supply and pen set up processes
Inventor: ALTENDORF JOHN M
IPC: B41J2/175
Filed: 1995-10-30
Abstract: The ink-jet pen (22, 24, Fig.1) comprises a body of polyurethane foam (130) mounted in an ink chamber (160,162,164). A rectangular ink pipe (168) extends from a bottom wall (174) of the ink chamber (160,162,164) between the walls (176,178) of the ink chamber (160,162,164). A wire mesh filter (136) is mounted to the ink pipe (168). The ink pipe (168) and mesh filter (136) extend into compressive contact with the foam (130) to locally increase the capillarity of the foam (130). Any air that comes out of solution collects as a bubble (320) in the rectangular ink pipe (168). The bubble does not block ink flow to a printhead (142) because the comers of the rectangular ink pipe (168) provide a fluid capillary path.

Title: Sandwich injection moulding of hard ring with soft edges e.g. for filter cover
Inventor: RAPP ERICH
IPC: B29C45/16
Filed: 1995-11-08
Abstract: A component, especially of thermoplastic, made by sandwich injection moulding, consists of a hard material, especially a ring, with a plate shaped edge enclosed by a flexible soft material. The hard material part (30) and the soft material part (40) are moulded in the same tool which has two halves (10,20) to determine the shape of the parts.  The hard material part (30) is injection moulded first and then sections (12,13,22,23) of the tool are moved so that a shaped cavity for the soft material part is formed.  The soft material part (40) is then injection moulded.  Preferably the upper mould (10) has a first part (11) which defines the shape of the hard ring (30) and is supplied through a nozzle (28).  The second (12) and third (13) mould parts define the shape of the soft edge (40) when a hydraulic actuator moves a cylinder (23) axially downwards. The soft edge material is supplied through a nozzle (26). A pin (27) provides a through hole in the hard component and is moved out of the way when the cylinder (23) moves downwards. The soft material fills the hole and is thereby keyed in. Several pins (27) are distributed round the circumference of the component.  The two injection processes follow in quick succession because little time is required to perform the movement of the tool parts (12,13,22,23).

Abstract: In a process for determining the thickness of a layer of electroconductive material, the measurement errors are converted into dimensionless standardised values by a standardisation process.

These standardised values are converted into layer thickness values by means of a calibration curve.
