Title: Measuring the pulse duration of ultra short light pulses in ultraviolet range - by superimposing weak ultra short UV pulse and ultra short and wave UV pump impulse inside a material which transmits both pulses
Inventor: ALBRECHT HANS-STEPHAN
IPC: G01J11/00
Filed: 1992-06-15
Abstract: The pulse duration of an ultra short light pulse is measured by superimposing a relatively weak ultra short UV measured light pulse (5) and an ultra short long wave pump impulse (1) inside a material (4) capable of transmitting both impulses. The two pulses can be focussed in a small volume area of the material with certain and changeable relative time delays and with a sufficient accute angle between the beam direction and suitable polarisation direction. The measured light pulse leaving the crystal is analysed and its energy measured and used in the formula (I) to calculate the pulse duration. The material (4) is pref. an isolator crystal with large band distances such as BaF2, SrF2, CaF2, LiF, MgF2. USE/ADVANTAGE - For measuring ultra short light impulses in spectral range 120nm-350nm. The intensity of the UV impulse can be quite small, restricted only by the sensitivity of the receiver. The method can also be used to determine the symmetry of the light impulse.

Title: Permeable rigid-plastics mats on car parks, playgrounds or temporarily on large green areas for staging events
Inventor: EHBAUER HUBERT-G
IPC: E01C9/00
Filed: 1993-02-17
Abstract: Car parks are able to breathe and be covered with greenery, likewise playgrounds, do not need to be asphalted over or concreted over, but at the same time can be clean: in the event of rain the water percolates through the mat pores; grass grows through the pores, since the permeable gravel substructure with greasy but loose topsoil layer provide ideal growth conditions for lawn grasses. The problem of asphalt or concrete in public or company places; of pools of water, ground which is trampled and thus may turn to mud, when it rains; of crushed plants, is thus overcome with the invention of the matting. The rigid-plastics mats are perforated to allow the ground to breathe, grass growth, percolating water, sunray absorption, i.e. are permeable on both sides. At the same time, they are able to withstand any loading, being up to 10 cm thick, and also displacement, for instance in winter during snow clearing, as a result of aluminium pegs at the edge of the mat. They should not, however, be gritted or sanded, which would block the pores. To prevent the pores from freezing over, heating coils are provided in the mats, which at the same time are connected to the mat-joining buttons and can be supplied with recovered energy. To delimit the mat area, attachable/detachable rectangular, triangular, curved or corrugated mat pieces are provided. The surface profile is formed from supporting knobs with longitudinal, transverse and diagonal webs, while the underside ... for the purpose of stable support ... with broader supporting knobs ...

Title: Method for analysing liquid or pasty materials to be analysed from a process fluid and system for carrying out the method
Inventor: KULICKE WERNER-MICHAEL PROF DR
IPC: G01N33/18
Filed: 1993-03-09
Abstract: The invention relates to a method for analysing liquid or pasty materials to be analysed from a process fluid, which consists of water, sediments and chemical auxiliary agents. The material to be analysed is brought to constant pressure and then passed through a filter, temporal variation in the throughput flow rate being measured. The temporal behaviour of the filtrate flow is then correlated with filtrate flow behaviours of known analysis fluids and, from the differences, the quantity and composition of the chemical auxiliary agents to be added to the process fluid are determined.

Title: Method and apparatus for repairing damaged pallets
IPC: B23D45/02
Filed: 1993-03-18
Abstract: To repair damaged pallets (100), a method is proposed in which the damaged pallet (100) is positioned and fixed on a machine table (21) in the upturned position. Thereafter, individual damaged bearers (103) and laths (102, 104) are removed. For this purpose, a separating member which is mounted on a machine frame (30) so as to be displaceable in three coordinate directions is located above the machine table (21). According to an advantageous embodiment of the invention, the separating member has a machine head (40). The machine head (40) carries a rotationally driveable saw blade (42) on an output shaft (41) oriented perpendicularly to the machine table (21). As a result, it is possible selectively to saw out the damaged components of the pallet (100). A further aspect of the invention relates to a separating apparatus (20) and also to a working line for repairing damaged pallets (100) on an industrial scale, the latter, according to a preferred embodiment, having the separating apparatus (20). <IMAGE>

Title: Process and device for mixing a liquid with a disperse solid, in particular an agglomerating solid
Inventor: MOELLER WERNER PROF DR ING
IPC: A23K50/10
Filed: 1993-04-27
Abstract: A process for mixing a liquid with a disperse solid takes place in a mixing tank (1), the liquid being introduced with the solid for turbulent mixing and the mixture being taken off from the mixing tank (1) for utilisation. In order to counteract agglomeration of the solid, i.e. lump formation, it is proposed that from the mixing tank (1) is already fed a premixed or ready-mixed mixture from a flushed addition vessel (2) for the disperse solid, by the solid being taken off owing to the suction action on a liquid passed through and being drawn in by a pump (4), further mixed and either pumped directly into the mixing tank (1) or run indirectly again via the flushed addition vessel (2) for enrichment with agglomerating solid and only then returned to the mixing tank (1). <IMAGE>

IPC: B62K19/36
Filed: 1993-05-21
Abstract: The saddle mounting bracket (11) is on a telescopic mounting with a support tube (6) sliding inside an outer tuber (2) fitted into the bicycle frame. An external control (14) operates a pneumatic control valve to adjust the pneumatic cylinder insert (4) inside the inner tube, to provide additional adjustment for the saddle height.The coarse adjustment is by a mechanical clamp (3) on the bicycle frame. The telescopic adjustment has ball bearings (7) operating in vertical grooves for the fine adjustment. This prevents the saddle from rotating in position.

Title: Damping device
Inventor: GODEL MARTIN
IPC: F15B15/22
Filed: 1993-07-05
Abstract: A damping device is proposed in which two walls (9, 10) movable relative to one another define a damping space (13) from which a fluid is displaced via an outflow opening (15) during a damping section of the relative movement between the two walls (9, 10). A regulating member (18) which can be adjusted for the variable presetting of the outflow cross-section is allocated to the outflow opening (15). There is an actuating member (23) for the adjusting drive of the regulating member (18). Of the two members (18, 23), one is designed as a magnet device (24), while the other is made of an electrically conductive material (25). The members (18, 23) are designed and arranged in such a way that they interact with one another according to the principle of an eddy current brake while the damping section of the relative movement between the two walls is being covered, the regulating member (18) predetermining different outflow cross-sections of the outflow opening as a function of the speed-dependent induction which occurs. In this way, damping of the movement is obtained, during which the relative speed of the two walls (9, 10) is automatically taken into account. <IMAGE>

Title: Sensor chip for high-resolution measurement of magnetic field strength
Inventor: DETTMANN FRITZ DR
IPC: H01F10/08
Filed: 1993-08-16
Abstract: A magnetoresistive sensor element is described, the resistive strips of which consist of elliptical regions, connected in series, of anisotropically magnetoresistive material, which regions have a minimum mutual separation, and in which connection takes place using non-magnetic conductive layer surfaces which zonally cover the elliptical regions such that the boundary lines of the conductive layer surfaces form an angle of approximately 45 DEG  with the longitudinal direction of the strips. The resistive strips of a voltage divider or of a bridge are arranged in a line, so that they can be fitted into a narrow gap of a flux-concentrator arrangement. The high field strengthening of the flux concentrator which can thus be achieved, and the slight rotatability of the magnetisation in the elliptical regions are a prerequisite for a magnetic-field sensor element with very high sensitivity.
