Patent DE-4227991-A1 (DE)
Title: Symmetrical concentric lens system with optimal aberration correction - has e.g. central sphere with 46 per cent of radius of outer shell of different glass for diffraction-limited error-free imaging
IPC: G02B3/00
Filed: 1992-08-21
Abstract: All radii of curvature and the plane of the image field are arranged concentrically around a common point which forms the centre of the aperture of the system. The radius of curvature of the image field is equal to the focal length. Spherical and chromatic aberrations can be corrected to any desired deg. by choice of suitable materials (e.g. fluorite for the inner sphere and ZK5 for the surrounding half-shells), with refractive indices and dispersions dependent upon the number of elements. A special CCD matrix detector may be divided into honey-comb like hexagonal elements for homogenous covering of the image field, while allowing correction of brightness fall-off at the edges. An optical fibre structure can be inserted parallel to the lens aperture for transferring the crooked image field onto a planar image field. USE/ADVANTAGE - For optical astronomy, addn. of any number of concentric surfaces does not affect symmetry or correction of coma, astigmatism, distortion and chromatic aberration.

Inventor: MORGENSTERN ERICH
IPC: F16K51/00
Filed: 1992-10-31
Abstract: The invention relates to a valve, particularly for a hose coupling, which is used when filling a tanker. The valve is a disc valve which is surrounded by a housing (2) and is held in a closed position by a spring (22).

Title: Holder for glass panels in building - has clamping device with different thermal expansion coeffts. to retain contact holding pressure when surrounding temp. changes.
Inventor: HAHN THOMAS
IPC: E04F11/18
Filed: 1992-11-28
Abstract: The clamping device (1) which holds the glass panel in position is formed so that its contact pressure on the holding area of the panel does not change when the temp. changes, even if these temp. changes alter the thickness of the holding area. The distance between the clamping jaws of the clamping device is reduced or increased when the thickness of the holding area reduces or increases as a result of the intermediate layers in or on the glass panel increasing or decreasing whilst the contact pressure remains the same. The clamping device has components with different thermal expansion coeffts. such as bimetal components. The clamping jaws can be connected by a bolt and sleeve using an expansion part with a greater expansion coefficient. USE/ADVANTAGE - Glass panels in a building are securely held in all temp. ranges even in the event of a fire.

Abstract: Flow limiter (10), having a differential pressure transmitter (12) and a differential pressure regulator (14) in a common housing (11), which influence the effective passage cross-section between a supply (16) having the pressure p1 and a discharge (18) having the pressure p2. The throttling element, which can be adjusted manually or by an actuator, for example by an electric motor, of the differential pressure transmitter part (12) is constructed in two parts and comprises, on a common valve stem (30), a cone (32) which is arranged loosely thereon and determines the cross-section of the differential pressure transmitter and an auxiliary cone (33) which is seated in a fixed position on the valve stem. The loose main cone (32) is held in contact with the auxiliary cone (33) via a spring (35) which is supported on a stop (36) of the valve stem (30). A bore (37) in the cone (32), which consequently forms the seat of the auxiliary valve, connects the upstream side of the cone (32) to the downstream side if the setting forces on the valve stem (30) are too small to lift the cone (32) from the seat; cf. drawing. <IMAGE>

IPC: E04H6/42
Filed: 1993-07-13
Abstract: The invention relates to a fall-prevention safeguard for parking platforms which can be displaced on a stationary base, with respect to which a lift can be aligned such that the parking platforms can be displaced from a stationary base on to a base, arranged on the lift, for the parking platform, having a securing lever which is mounted pivotably on the base and can be pivoted, counter to the action of a spring, out of a securing position in which it projects into the displacement part of the parking platform into a release position in which it is removed from the displacement path of the parking platform. In order, in the case of said fall-prevention safeguards, to achieve improved mounting of the securing lever, it is proposed that the securing lever be retained on the base by means of an elastomeric material which permits elastic pivoting over a restricted angle range.

Title: Moving yarn false twisting heater - has heated surface with projecting carrier surfaces to vary gap between moving yarn and heated surface for high temps. to give self-cleaning action.
Inventor: BRUSKE JOHANNES
IPC: D02J13/00
Filed: 1993-08-11
Abstract: The yarn heater, for false twisting, has a heating body with a number of spaced supporting carrier surfaces (12) to hold the yarn (1) at a gap from the heated surface. At the entry section, (3) the yarn guide (9) and the carrier (12) are at relatively large intervals and the carrier surfaces are at a small gap from each other in the control section (4). Pref. a further section (5) of the assembly, after the control section (4), has a large gap between the carrier support (12) and the exit yarn guide (10). The yarn (1) is displaced from the heated surface at the entry section (3) at a larger gap than in the control section (4) by a factor of 2-15 and pref. 3-10, with a similar gap between yarn (1) and heated surface at the final section (5). At the leading section (3), the yarn guide (9) has pref. no thermal contact action and/or the carrier support (2.1) at the end of the section (3) has thermal contact with the heated surface from the control section (4). USE/ADVANTAGE - The appts. is for heating the yarn to the temp. required for the false twisting process. The yarn temp. is determined by its gap from the heated surface, so that the body can be heated to a constant temp. of 300-350 deg.C for a self-cleaning action.

Title: Photographic method of joint and spinal mobility using lights attached to limbs - using LED's, battery power and subsequent analysis of photo MMTS by neutral-O-method
Inventor: TSCHAN PETER DR
IPC: A61B5/11

The procedure follows the 'neutral-O-method' for joint mobility measurement. The angular movement may then be measured using the photograph. A number of lamps may be used for spinal vertebrae measurements. ADVANTAGE - Reproducible accuracy of physical mobility measurement.

Title: Fuzzification method
Inventor: GE SHUANGSHENG DIPL ING
IPC: G05B13/02
Filed: 1993-10-14
Abstract: At present, the association functions are defined with a large number of assumptions. These assumptions often contradict the results of psychophysical investigations. However, the control quality of fuzzy control tasks is distinctly improved using the association functions determined in these investigations. The novel method enables the association functions to be calculated in such a way that they have the properties of the experimentally determined association functions. The peak abscissae are calculated, with the use of an exponential equation, in accordance with the details regarding the number of terms and the variation range of the basic variable. The basic variable is then divided by the peak abscissa of a term and exponentially transformed. The transformation is then inserted into the property function of the corresponding linguistic variable which was defined beforehand. The association function of the term is produced thereby. Fuzzy control and control engineering.

Title: Vehicle security circuit e.g. for cars, motor cycles, motor boats and light aircraft
Inventor: GEBHARD DIETRICH
IPC: B64D45/00
Filed: 1993-11-18
Abstract: A security circuit for registering and announcing unauthorised handling of a car is either automatically activated and/or deactivated, or does so at the behest of the user. An electronically coded key (32) is used for this. There is a transmitter (24) which sends out an alarm signal (27) if unauthorised handling is registered. There are several push-buttons concealed in the car for the activation/deactivation. The activation initiates a locking system preventing the car from being driven away, such as hindering the electronic engine management system. The alarm signal only ceases when an external answering signal (31) is received. The alarm unit has an independent power source (35) from the car battery.
