Title: Sensor for measuring the filling level of fluids
Inventor: ROSBERG RAINER DIPL ING
IPC: G01F23/296
Filed: 1993-05-15
Abstract: In a miniaturised field, for example in medical technology or in chemical laboratory technology, known sensors cannot be used in every case, since, on the one hand, they are of too bulky a construction and, on the other hand, too much electrical power must be used for their operation. The new sensor is intended to occupy a small constructional space and to be able to be operated with batteries. As a resonance element, a piezoelectric tube (11) is used, which has a capillary longitudinal bore (14) and internal and external metallising (12, 13), in connection with an electronic circuit (20) for applying a voltage of high frequency to the tube (11). The electronic circuit (20) generates a frequency band which includes the resonant frequencies for the transverse oscillation of the empty and more or less filled tube (11). The electronic circuit (20) makes available at its output a signal which is dependent on filling level.   The miniaturised sensor, which is of compact construction and operates in any position of use, is able to function in all fluids, even coloured ones. It needs only a little electrical power and can accordingly be supplied with power without problem from a battery or from solar cells. The new sensor always operates equally well irrespective of the ambient temperature and responds without delay. <IMAGE>

Title: Process for producing an edge guard as a border on decoratively covered mouldings
Inventor: GRUENHAGEL OTTO
IPC: B29C45/14
Filed: 1993-05-24
Abstract: In the production of covered mouldings, preferably moulding provided with an injection-moulded rear coating, the outer edges and the edges around clearances and openings in the mouldings must be protected in particular against fraying and detaching of the covered material. This is achieved by the present invention in that these edges are provided with an edge guard running around them, which may also be of a partial form and designed in various shapes and contours. In addition, it is possible to design the respective moulding not only with the outer, running-around edge guard but also with a sheet-like edge guard provided on the edge regions. Production and application are performed by means of suitable gating systems, which inject a thermoplastic material into the mould cavities formed into the plastics injection moulds, corresponding to the shapes of the borders, and at the same time form the edge guard.
Patent DE-4326856-A1 (DE)
Title: Roll for use in damping systems of offset printing machines or offset printing processes
Inventor: FUEHRER JUERGEN DR
IPC: B41N7/04
Filed: 1993-08-11
Abstract: In leverless damping systems of offset printing machines, addition of isopropyl alcohol is unnecessary or the added amount can be drastically reduced if the immersed roll or damping application roll is a roll having a coating of elastomeric material having a surface roughness Rz of between 6 and 20  mu m. The desired roughness is achieved by setting appropriate grinding parameters. The lower wetting capacity of the damping solution which occurs due to the reduced added amount of isopropyl alcohol can likewise be compensated by a roll having a coating of elastomeric material in which the elastomeric material contains an admixture of chopped fibres made from hydrophilic plastics.

Patent DE-4328479-A1 (DE)
Title: Drainage-gutter system
Inventor: ARM WOLFGANG
IPC: E01C11/22
Filed: 1993-08-24
Abstract: Drainage-gutter systems for channelling away surface water are known, which comprise at least one discharge gutter with a discharge opening for channelling away water from the drainage-gutter system as well as conduit gutters without discharge, which can be joined to the discharge gutter to form a gutter line. Each of the gutters exhibits side walls which are connected via a base and are intended for forming a throughflow base, and further exhibit a covering grating with through-passage openings through which water can be channelled into the throughflow space and along this to the discharge opening. In order also to be able to dispose of loaded waste water in a simple manner, it is proposed that the base of the discharge gutter be arranged to be lower than the base of the conduit gutters, that a separator be formed, the discharge opening opening into the separator above its base such that the lowest point of the said opening is located essentially level with the base of the conduit gutter adjoining the discharge gutter. Furthermore, the discharge gutter comprises a covering which is arranged beneath its covering grating and which is arranged to cover over the separator such that water flowing in through the through-passage opening of the covering grating cannot pass directly into the separator.

Patent DE-4402552-A1 (DE)
Title: Process for producing defined surfaces on fibre-composite components with a thermoplastic matrix
Inventor: FUNCK RALPH
IPC: B29C59/04
Filed: 1994-01-28
Abstract: Fibre-composite components which are produced by a winding or braiding method in some cases have a rough outer surface. This is often not desired. When improving the surfaces by means of pressure rollers or pressure shoes, the adhering of fibres and matrix presents a problem. Displacements of the fibre layers occur, the pulling out of individual fibres and in some cases damage to the fibres. With the process according to the invention, these problems are avoided. A metallic strip (3) with a defined, in particular smooth, surface is wound under pretension onto the molten component (1) and is unwound again after cooling of the matrix. In this way, the rough surface texture (a) is transformed into a defined surface (d). The spiral burr (c) can be removed subsequently by means of a cutter (4). The process permits the production of defined outer surfaces on fibre-composite components produced by the winding or braiding method with a thermoplastic matrix. Damage to and displacements of the fibres are avoided, and it can be integrated well into the respective production process. <IMAGE>

Inventor: HILFINGER PETER
IPC: A46B13/02
Filed: 1994-10-29
Abstract: Described is an electric-toothbrush head (1) with a support tube (2) in which is mounted a shaft (7) running along the longitudinal axis (3) of the tube. Two bristle carriers (14, 15) are mounted to rotate about particular axes (24, 25). The invention also calls for means, in particular two piston rods (30, 31), to link the shaft (7) to the two bristle carriers (14, 15) in such a way that movement (36) of the shaft (7) causes a rotational motion (37, 38) of the two bristle carriers (14, 15) about the two bristle-carrier axes (24, 25). The bristle-carrier axes (24, 25) are located in a plane disposed approximately at right angles to the longitudinal axis (3) of the tube, with an angle of approximately 90 DEG  between them. The motion of the shaft can be either a rotary motion about the longitudinal axis (3) or a longitudinal motion along the longitudinal axis (3). In addition, the bristle carriers (14, 15) can be mounted on arms (60, 61) so that they can pivot, in particular about the longitudinal axis (3).

Title: Mechanical or electromechanical propulsion system for vehicle
Inventor: WICKE WALBURGA DR
IPC: B60K8/00
Filed: 1994-12-08
Abstract: The alternative drive system is used in a vehicle stuck in a traffic jam, where the traffic is stationary most of the time and moves forward slowly for a short distance when it moves at all. The engine is stopped, reducing the generation of unwanted heat and exhaust fumes.The drive system uses a foot pedal or a hand lever which is actuated by the muscular strength of the driver to move the vehicle forward slowly. A system of rods or a hydraulic system may be used to transmit the drive. This transmission may be changed from the active to the inactive state by a control knob on the dashboard which ensures that it can only be used when the engine is stopped.
