Patent DE-3715349-A1 (DE)
Title: Support cradle for lifting vehicles under the wheels
Inventor: ESSMANN JOHANNES WILHELM
IPC: B66F7/10
Filed: 1987-05-08
Abstract: In the current state of the art, diagnostic car lifts fitted either with drive-on runways or support cradles that grasp under the body are used in garage workshops. Those car lifts fitted with drive-on runways require much floor space, are difficult to drive on, and cover a large part of the underfloor of the vehicle. If the diagnostic car lifts are built to grasp under the body, they require an excessively long set-up time which the operator has to spend in an uncomfortable position. The invention consists of a support cradle that is connected to one or two jacks of a one-jack or two-jack car lift that can retract into the floor. Instead of drive-on runways, the support cradle has very shallow, sprung support frames (3) that grasp under the wheels; it can be adjusted to the vehicle's wheel base by a foot control, and only covers a small part of the vehicle's bottom. Another significant advantage is that the support cradle only presents a small obstacle for a car that is to be pushed. <IMAGE>

Title: Method and apparatus for the exchange of run-off bobbins for full bobbins on ring-spinning and ring-twisting machines
Inventor: ZEISER MICHAEL A
IPC: D01H9/00
Filed: 1987-06-04
Abstract: Method and apparatus for the exchange of run-off bobbins for full bobbins on ring-spinning and ring-twisting machines, in which the bobbin rails receiving the bobbin carriers are movable by means of carriages or slides in the creel carriers designed as rails or sliding surfaces, in such a way that the run-off bobbins are exchanged for full bobbins outside the machine width. Even after the bobbin rails loaded with full bobbins have been moved into the working position, a run-through rail always remains outside the machine width and makes the connection between the supplying and the discharging transport rail, with the result that a subdivision of the creel into sections also allows unloading and loading.

Title: Process for producing and applying carrier means for natural grass
Inventor: REPPERT RUEDIGER LOTHAR VON DI
IPC: E01C13/08
Filed: 1987-07-15
Abstract: A description is given of a process for producing and applying carrier means for natural grass, in the case of which carrier means a ground/floor covering, provided with equal-length supports in the manner of a hedgehog, bears a cover panel which is perforated or configured in the manner of a grid, and the interspace is filled with absorbent or moisture-absorbent filling material, which is capable of growth and serves as cultivated ground, and grass seed is provided thereon, said grass seed strongly taking root beneath the cover panel and growing on the same to form a closely packed carpet of grass. Carrier means of this type are predominantly suitable for most types of indoor games, for example for indoor football, where they replace the hitherto conventional synthetic-grass flooring, and also for open-air grass-covered surfaces which are damaged by a high degree of wear or too much rain, e.g. for tees and greens on golf courses or goal and penalty areas on football pitches, and for desert regions, where nothing grows, for laying on areas of sand which are thereby rendered fully capable of growth. In place of the supports integrated in the ground/floor covering use may also be made, for the purposes of reliable stability and bearing, of load-bearing frameworks, and the entire carrier means may be produced from ground, waste car tyres or other rubber or plastic waste materials, the resulting ground material, mixed with rubber solutions or other solutions, being rolled out and/or pressed to form webs or panels.

Title: Pressure intensifier with two separate pressure-medium circuits
Inventor: KUCHARZYK REINHARD ING GRAD
IPC: F03C1/06
Filed: 1987-11-02
Abstract: Pressure intensifiers are special hydraulic units for converting the pressure of a driving primary pressure-medium circuit, the pressure medium of which is hydraulic oil, into another pressure of a driven secondary pressure-medium circuit, the pressure medium of which can be water. Normally such pressure intensifiers consist of a hydraulic motor which drives a pump. Due to the invention, the primary pressure-medium circuit drives individually controlled motor pistons (22) which are arranged in a circle and which furthermore, driving longitudinally coupled pump pistons (25) in a pump part (8), form a secondary pressure-medium circuit controlled by non-return valves. In this arrangement, the independent control of the motor pistons (22) for their stroke movements is effected by cam plates (9, 11) which are driven by the motor pistons (22) and which in turn bring about the greater strokes of the control sleeves (19) and perform a reversal by compression springs (20) in the face of external forces for protecting the independent-control device. <IMAGE>

Title: Process for the cultivation of cells in a fermenter, and fermenter intended for carrying out the process
Inventor: MAERKL HERBERT PROF DR ING
IPC: C12M3/06
Filed: 1988-06-02
Abstract: The invention relates to a process for the cultivation of cells in a fermenter in which the cells are arranged on bead-like granules which are disposed in the fermenter and to which liquid cell culture medium is fed by a pump unit and, after flowing through the granules, is removed again from the cell culture chamber of the fermenter, and to a fermenter intended for carrying out the process. The culture medium is conveyed by a pump into a pressure chamber and from the latter into at least one pressure tube which is open at one end, is designed as perforated tube and is passed through a fixed bed of macroporous particles. The culture medium penetrates through the wall of the perforated tube into the fixed bed, flows through the latter and then emerges from the fixed bed again. Outside the fixed bed, the culture medium flows back to a base chamber below the intake of the pump and is conveyed anew into the pressure chamber. Nutrient medium and, where appropriate, gases are fed into the culture medium, and waste products and gases are removed from the culture medium, through a semipermeable membrane.

Inventor: HAHN TILL
IPC: E05B65/08
Filed: 1988-07-20
Abstract: The sliding door of showcases is normally closed by means of safety locks, but these have to be installed with a high degree of accuracy if the side wall is to have no play in the position of rest. The new device will likewise make it possible to close a showcase securely, but without having to ensure particular accuracy during installation. The sliding door 4 is held in the closing position or position of rest by permanent magnets 7 which are attached to the showcase and the magnetic field of which can be cancelled via an electrical winding by the flow of an appropriate direct current. Since the permanent magnets do not have to be installed with such accuracy, the assembly of a showcase of this type can also be carried out outside a workshop, for example a building site. Furthermore, the secure closing of sliding doors can thus be brought about, even in places where conventional closing devices would be accessible only with difficulty.

Title: Swirl-nozzle unit
Inventor: RITTER HELMUT
IPC: D02J1/08
Filed: 1988-09-12
Abstract: A multiplicity of parallel tubular air-swirl nozzles (5) are held in a row in the wall of an air-supply pipe (4). Each of the nozzles (5) possesses a continuous yarn channel, into which an air-supply bore (6) opens laterally. The air-supply bores (6) of all the nozzles (5) communicate with the interior of the air-supply pipe (4), to which compressed air is supplied. A yarn-guide eye (8, 9) is respectively arranged upstream and downstream of each nozzle (5) in the running direction of the yarns (10, 11). All the yarn-guide eyes (8, 9) are held in a casing (2) which encloses the air-supply pipe (4) together with the nozzles (5) and which possesses a waste-air orifice (3). Connected to the waste-air orifice (3) is a suck-off device which sucks off the air emerging from the nozzles (5) out of the casing (2). Thus, no disturbing air streams and no fibre fly can escape out of the unit through the yarn-guide eyes (8, 9). The yarn-guide eyes (8, 9) are designed as tubes which project into the interior of the casing (2), in order there to protect the yarns (10, 11) from disturbing air flows. <IMAGE>

Title: Method and device for the simulated generation of a substitute signal
Inventor: KRINITZ REINER
IPC: F02D41/06
Filed: 1989-04-07
Abstract: In water-cooled internal combustion engines two temperature sensors are normally used in order to determine the engine or water temperature on the one hand and the intake pipe or intake temperature on the other. According to the present invention the temperature sensor for the intake pipe or intake temperature is dispensed with and a substitute signal for the intake pipe or intake temperature is formed from the temperature signal of the temperature sensor for the engine or water temperature. This is achieved in that two functional correlations for the respective engine type are measured once by means of two temperature sensors and stored. For operation of the engine on each future occasion, the engine starting or initial water temperature and the instantaneous engine or water temperatures which occur during warming up are then measured in order to then generate the substitute signal by way of the two stored functional correlations. The said measures can also be used for other applications in which, from a first measured signal characteristic, a substitute signal for a second, similar signal characteristic is to be generated by way of fixed functional correlations.
