Patent DE-3804264-A1 (DE)
Inventor: RUCHHOLTZ CARSTEN DR ING
IPC: H01R9/26
Filed: 1988-02-11
Abstract: For the overheating protection or overload protection of, in particular, ballast units, a connecting terminal has a base body in which at least one terminal insert (2') with two connecting contact points (3') is provided, which contact points are electrically insulated from one another. Their conductive connection is achieved by means of a current- or temperature-sensitive protecting element (5) which is arranged in a retaining chamber (4, 4'), offset from the terminal inserts, and is connected to the two connecting contact points (3'). These contact points are constructed on two individual terminal bodies (12), each of which has a screw terminal for the conductor which is to be connected or the contact tongue of the ballast unit and a connecting contact element, designed as a crimped terminal or terminal clip for one contact end of the protecting element. The walls (6) of the retaining chamber (4) also provide air and leakage paths which are also adequate for transformers with relatively stringent safety requirements. <IMAGE>

Title: Process for dyeing natural and/or synthetic polyamides
Inventor: FRAUENKNECHT JOSEF
IPC: D06P3/10
Filed: 1988-02-24
Abstract: The invention relates to a process for dyeing natural and/or synthetic polyamide fibres with anionic dyes, characterised in that the polyamide fibres are dyed at a temperature from 60@C to 105@C with a dyeing liquor which contains at least one anionic dye together with a cationic (cation-active) auxiliary which has affinity for the dye(s), and an anionic auxiliary is added to the dyeing liquor at a time 15 to 60 minutes after the dyeing temperature has been reached in order that the exhaustion of the dyeing liquor may be completed. The dyeings obtained are level and show good penetration.
Patent DE-3809070-A1 (DE)
Inventor: BLOTENBERG WILFRIED DIPL ING
IPC: F04D27/02
Filed: 1988-03-18
Abstract: In the case of known control methods for turbocompressors, in order to prevent surging before the working point of the compressor reaches the surge limit, it is ensured by controlled opening of at least one venting or reversal valve on reaching a venting line parallel to the surge limit that the flow through the compressor does not fall below a minimum through-flow which varies as a function of the delivery pressure. The disadvantage to these known methods is that surging cannot always be reliably prevented, particularly in the case of rapid shifts in the working point in the direction of the surge limit. The new method is intended to avoid this disadvantage. 
<??>The new method proposes that in addition the rate at which the working point shifts in the direction of the surge limit be determined in the performance characteristics and that if a rate-related rapid opening line running at various distances from the surge limit is exceeded, rapid opening of the venting or reversal valve be superimposed on the normal venting control. This means that opening of the venting valve occurs at the latest possible moment but always in sufficient time. The compressor can thereby still be operated safely at levels closer to its limit which results in more economic partial load operation and greater surge safety. 
<??>The new method is suitable for controlling turbocompressors for widely varying applications, for example in blast furnace blast generators, in petrochemical processes or the manufacture of fertilizers.

IPC: H01B15/00
Filed: 1988-07-08
Abstract: The invention relates to a process for dividing up and recovering the individual materials from old cables. For this purpose, the cable mixture is sorted into individual constituents and cut to size, the outer plastic sheath is removed by being slit open, and the individual cores are fed to a disk comminuter. It is essential, at the same time, that the disk comminuter should cut up the individual plastic-sheathed cables or the cable composed of several individual cables into short cable pieces of a length of 3 to 10 mm in a salami-like manner. Because the pieces are very short, the short cable pins are separated from the plastic ring arranged round them on a following vibrating screen.

Title: Method and arrangement for the determination of the thermal resistance of IGBT components
Inventor: BAYERER REINHOLD DIPL ING DR
IPC: G01R31/26
Filed: 1988-09-22
Abstract: It is the object of the invention to specify a method and a measuring device for the determination of the internal thermal resistance and the transient thermal resistance of IGBTs (insulated gate bipolar transistors), which also permits a measurement on IGBTs with a reverse-connected parallel diode. This object is achieved by means of a method for the measurement of thermal resistance in which the collector-emitter voltage of the IGBT is measured before and after a defined power pulse as well as by means of a method for the determination of the transient thermal resistance by means of detecting the cooling curve after the power pulse, and specifically by means of measuring the collector-emitter voltage at specific time intervals. The methods can be carried out with a measuring device connected to a computer. The solution according to the invention can be used for the testing of IGBT modules. <IMAGE>
Patent DE-3837927-A1 (DE)
Title: Flow indicator
Inventor: KINAST PETER
IPC: G01F1/28
Filed: 1988-11-09
Abstract: The invention relates to a flow indicator in the drip chamber of medical transfusion systems. At flow quantities above 10 millilitres per minute, the flow quantity can no longer be determined by the usual drop rate, because a continuous stream of the medium forms in the inlet of the drip chamber. By means of an impact plate mounted on a spring and a scale applied to the transparent wall of the drip chamber, the volume flow of the flowing medium can be made visible and indicated to an order of magnitude, in that the stream directed onto the impact plate presses this downwards in the chamber against the spring force. The flow occurs via the gap between the outer diameter of the impact plate and the chamber wall, which is so dimensioned that a deformation of the chamber wall during air removal from the drip chamber does not lead to jamming of the impact plate. The impact plate is guided in the longitudinal direction by means of a pin which is fixedly inserted in the impact plate or in the counter-disc.

Title: Tilt-away writing surface for seats
Inventor: HEINZEL EBERHARD DIPL ING
IPC: A47C7/70
Filed: 1989-02-06
Abstract: Writing surfaces for seats are usually integrated into the chair, so that the armrest must have a different shape, or they are constructed individually in the case of a chair without armrests. In general, it is required that the writing surface be capable of being tilted away when not in use, so that the chair can be used in normal fashion. In known embodiments, this can be achieved only by performing a plurality of pivoting operations, which requires a complicated and expensive fitting. In order to provide a writing surface which has a simple fitting in terms of its construction and functioning, a clamping head (5) is attached to the seat (1) in such a way that it can be laterally adjusted and locked with respect to the latter. In this clamping head, a column (4) is guided obliquely rearwards and downwards and is capable of being locked. The writing surface (2) is mounted at the upper end of the column (4) in such a way that it can be pivoted from a vertical out-of-use position into a horizontal use position. The new writing surface can be moved into the functioning position and into the out-of-use position with few and simple manipulations and is suitable for virtually any piece of seating furniture. <IMAGE>

Abstract: In the case of a gas-blast circuit breaker having two contact pieces (1, 2), at least one of which is constructed to be hollow for the dissipation of switching gases, and having a blowing device which consists of a piston (3) and cylinder (4) and produces an extinguishing gas flow as a result of a relative movement between them, an insulating material tube (7) is arranged in the course of the extinguishing gas flow, which tube (7) is perforated on the outside, encloses the arc combustion space (8) during the extinguishing phase, and is coupled to the moving part (4) of the blowing device. The cross-section of the insulating material tube (7) which is available for the extinguishing gas to pass through is smaller than the cross-section of the tubular contact piece (1, 2) which is intended to dissipate the switching gases. In order to optimise a gas-blast circuit breaker of this type, the cross-section of the insulating material tube (7) which is available for the extinguishing gas to be passed through is dimensioned to be in a range between one quarter and one eighth of the cross-section of the tubular contact piece (1, 2) which is intended for dissipation of the switching gases. <IMAGE>
