Patent DE-19711846-A1 (DE)
Title: Mechanical vibration damper, e.g. for helicopter engine vibration damping
Inventor: SEIDL WERNER DR
IPC: B64C27/00
Filed: 1997-03-21
Abstract: The damper consists of a spring (8) between vibrating and supporting structures, a pivoted transmission lever (16), and a weight (18) on the end of the lever. The spring is in the form of an elastic titanium bellows which has a low ratio between its inner and outer diameters. The bellows spring is made from a series of discs (28) welded together by electronic bombardment, and the weight (18) is in the shape of a curved member which partially covers the outer surface of the spring with a distance between the two. The length of the lever between the weight and the articulated joint (24) can be adjusted, e.g. by a motorised drive, and the articulated joint (24) and pivot (20) have bearings of elastomer with low damping properties.
Patent DE-19712655-A1 (DE)
Title: Chipless formed valve plunger as hollow-walled housing bowl and cam
Inventor: SAILER PETER
IPC: F01L1/20
Filed: 1997-03-26
Abstract: The material of the valve plunger recess (12) should either form part of the thickness of the adjuster (6) or be used to hold this (6). The hollow cylindrical wall (2) of the general housing (1) goes over at base level (3) into a double-walled folded edge (4), used here to provide the space (5) for the adjuster (6). Housing walling (2) and base (3) have two spaced (8,9) incisions (10) arranged in the peripheral sense so as to form a free tongue piece (11) bent round in its turn parallel to the base (3). The tongue should be bent round towards the adjuster from above or below the base and thus runs in the direction of the gas exchange valve shaft (7). Tongue and base are firmly joined by welding, soldering or bonding, and the tongue extends peripherally by at least one valve shaft diameter. The folded edge (4) runs in cone shape towards the adjuster (6) and the base (3) in a variant can be fitted with two specifically flexible tongues running parallel to the base axis so as to engage respective slots in the adjuster element (6).
Patent DE-19719258-A1 (DE)
Title: Tube-and-plate pack of condenser or evaporator
Inventor: HAUSSMANN ROLAND
IPC: B23K1/00
Filed: 1997-05-07
Abstract: The tube-and-plate pack is made of aluminum or an aluminum alloy. It consists of sandwiched rows of flat tubes (2), zigzag plates (4) between them and side closing plates (6) to complete the condenser or evaporator of a vehicle air conditioning plant. At least one of the closing plates bulges out in such a way that the bulge levels out the tolerances of the flat tubes and the zigzag plates. If both plates are bulged, the bulging is equal, so that the combination of the two bulges levels out the tolerances.
Patent DE-19723866-A1 (DE)
Title: Method to detect correct polarity of inductive signal generator
Inventor: FAHRBACH WILHELM
IPC: G01P3/489
Filed: 1997-06-06
Abstract: The method is for detecting the polarity of an inductive signal generator (3), which has a positive and a negative half cycle for each sampling event, which are generated by projections (2) on a fly wheel attached to a crankshaft (1) and which comprise the impulse signal (S1). The method involves producing a threshold value (T) from the impulse signal zero value, and generating an evaluation square wave signal (S2) from a half cycle of the impulse signal between the time at which it equals the threshold value and the time at which it equals or crosses the zero level. A keying ratio determination step determines the keying ratio of the evaluation signal. An acceptance or rejection step, which depends on the keying ratio determination, decides whether the polarisation is correct, which is when the keying ratio is equal to or less than a predetermined value.

Title: Volume flow rate measuring process for injection jets
Inventor: FOLLENDORF H-MICHAEL DIPL ING
IPC: F02M65/00
Filed: 1997-06-24
Abstract: The measuring process involves supplying checking oil by a hydraulic pump (2) from a tank (1) to a hydropneumatic store (7) up to a set pressure. The filling valve (3) is then closed and a measuring valve (8) fitted to the injection jet (9) is opened, so that the checking oil flows from the hydropneumatic store vie the injection jet into the tank. The fall time between the two set pressures in measured, and the mean volume flow rate is calculated from this. The control operations, measurements and calculations may be controlled electronically by a microprocessor.

Patent DE-19735031-A1 (DE)
Title: Recombination injection moulding of thermo-, duro- or elastomeric plastic
Inventor: EHRITT JUERGEN
IPC: B29C45/17
Filed: 1997-08-13
Abstract: The injection nozzle (3) in this case reaches into the mould and compressed gas (or liquid) is introduced from an injector in the section of the cavity (2), forming a cushion between cavity wall and melt. The moulding hardens, pressure is released and the moulding is extracted. The novel features include successive introduction of melt into sections (10, 11) of the cavity. Melt from both sections is recombined at a location (12) remote from the injection nozzle. The pressurised gas enters via a microporous mould section (13) corresponding to the shape of the moulding. This is located at the recombination point. Here, tempering elements (14) are located, to control melt hardening. An Independent claim is included for equipment carrying out the method. Gas injection is a function of: pressure in the cavity, elapsed cycle time and/or injection screw displacement. Gas pressure follows a given profile over time. The microporous section is heated or cooled for a desired interval, either preventing premature setting (especially), or alternatively inducing rapid setting of the appropriate plastic types. Further injector(s) may be used to inject the melt interior with gas.

Patent DE-19750123-A1 (DE)
Inventor: WIENAND KARLHEINZ DR
IPC: H01C17/28
Filed: 1997-11-13
Abstract: The invention relates to a method for producing a sensor arrangement for measuring temperature, comprising a temperature-sensitive measuring resistor which has a thin metallic resistance layer and bare contact surfaces on a ceramic substrate, said resistance layer being externally, electrically insulated. The contact surfaces are electroconductively and directly, mechanically, permanently connected to strip conductors on a ceramic support element. The strip conductors are electrically insulated from each other and are resistant to high temperatures. The measuring resistor is contacted and fixed on a pre-prepared support element by means of placement and burning in.

Contact surfaces for connecting a plug or cable are located at the end of the support element which faces away from the measuring resistor. The temperatures sensor, a standard component in the form of a flat measuring resistor, is placed on the ceramic support element wirelessly as an SMD component. The sensor arrangement produced according to the inventive method is suitable for measuring temperatures even above 400  DEG C.
