Title: Safety knife
Inventor: LOHRENGEL DENNIS
IPC: B26B5/00
Filed: 1993-05-10
Abstract: The invention relates to a safety knife having alternative blades, having a casing composed of two side pieces and a movable blade which is retracted into the casing when the cutting action has been completed. Knives are dangerous tools, as their blades are fixed and exposed. The greatest danger of injury occurs when the blade emerges from the cut material during use and the residual energy of the cutting movement is released in an uncontrolled fashion. The object of the invention is further to develop known safety knives in such a way that the danger of injury is minimised.

IPC: F21V9/04
Filed: 1993-05-18
Abstract: A light projection system is claimed which is preferably used for technical and medical endoscopies. The subject-matter of the invention is a lamp carousel (lamp revolver) 10 which can be inserted in a light projector 100 and has at least two light sources 20i which emit light rays (beams) preferably in one direction. The light sources are distributed over the circumference of a rotatable body and, when set in operation, emit their bundles 40 of light rays at a predetermined angle. In addition, the invention has as subject-matter a heating device 20i, 75 for optical instruments which are optically connected to a light source in order to receive light generated by said light source and to make it available for illumination purposes.

Patent DE-4323524-A1 (DE)
Title: Sealing arrangement
Inventor: OSSENBERG UWE
IPC: H02G15/113
Filed: 1993-07-14
Abstract: The proposal is for a sealing arrangement which primarily comprises a sealing web formed integrally on the upper region of a first component and a sealing groove formed in the lower region of a second component, the sealing web engaging in the sealing groove to ensure sealing. In order to provide a sealing arrangement which manages without the use of a flexible sealing element, the sealing groove is designed with a bell-shaped cross-section at its free mouth region, which faces the sealing web, and a roof-shaped cross section in the base region providing the connection between its two legs. The sealing web too is of roof-shaped design at its free end region, which faces the base region, but is slightly wider than the sealing groove in the base region, the angle of inclination of the free end region being slightly steeper than the angle of inclination of the base region. A ramp-shaped widening of its two side walls makes the foot region of the sealing web too slightly wider than the narrowest point of the free mouth region of the sealing groove.

Patent DE-4327449-A1 (DE)
Title: Process and apparatus for exchanging balcony parapets
Inventor: HAKERT KARL OTTO DIPL ING
IPC: E04B1/00
Filed: 1993-08-14
Abstract: The invention relates to a process for exchanging balcony parapets on buildings constructed using concrete slabs, and to apparatuses for carrying out the process. The object of the process according to the invention is to make it possible to exchange defective balcony parapets in a quicker and more cost-effective manner than has been possible hitherto, the intention being, at the same time, largely to avoid any danger to the workers. The invention achieves this object in that it provides an auxiliary railing, as a result of which all work can be carried out safely from the balcony. The old and new balcony parapets can be transported by an external transporting means. The new balcony parapets are designed especially for insulation in buildings constructed using concrete slabs. They exhibit retaining plates which can be fixed on the balcony side walls and on which the new balcony parapets can be fitted. Consequently, quicker and simpler installation is made possible. Moreover, damage to the base slab of the balcony is avoided.
Patent DE-4328314-A1 (DE)
Title: Mixing and supply silo for powdered bulk goods
Inventor: KRAUS WERNER DIPL ING
IPC: B65D88/72
Filed: 1993-08-23
Abstract: The large-volume silo with diameters which are greater than about 20 metres is used for the long-term storage and homogenisation of powdered, fluidisable bulk goods. A constructional shape which is especially favourable in terms of the investment is offered by setting the silo bottom 2 according to the invention directly on cultivated ground 16, so that costly foundations and supporting constructions can be dispensed with. On the flat cultivated ground 16, tunnel line prepared elements 15 are combined to form intrinsically closed tunnel lines 3, 4 and, between these tunnel lines, filling materials such as gravel and/or lean concrete are placed as far as the tunnel upper edge, so that the dispersion base (bottom) 2 is produced without any shuttering. The tunnel lines 3, 4 have a relatively large number of inlet openings 5 with frictional barriers, which consist of the intermediate bases 6 with air supply grooves 9, arranged thereunder. Each inlet opening 5 has assigned to it dispersion sections having air supply grooves 8 which are ventilated only alternately with associated air supply grooves 9. In so doing, the frictional barrier is released and the fluidised bulk goods can flow unimpeded into the relevant tunnel line. From the collecting and discharge tunnel 4, the bulk goods can be carried out via the discharge stubs 11 and the connected metering slide 13. The standard tunnel prepared parts, having the same constructional size, can be put together in a variable manner for all silo bottom shapes and sizes. <IMAGE>

Title: Method and device for informing persons about objects
Inventor: SOMMER ARND MICHAEL
IPC: G06K17/00
Filed: 1993-10-11
Abstract: A method and device for informing a multiplicity of persons about a multiplicity of objects, for example exhibits in a museum, uses a communications unit for each object which has a receiver and a transmitter. Every visitor to the exhibition similarly receives a communications unit which contains a transmitter, a receiver and a memory with stored information on all the objects. If the visitor would like more detailed information on a specific object, he actuates his unit which transmits a sequence of signals. Each signal contains the unique identifier of the unit allocated to the visitor and an identifier of an object. The identifier of a different object is transmitted with each signal in the sequence of signals. As soon as the communications unit of the object recognises its own identifier in the signal, it transmits back an activation signal with the identifier of the visitor's unit. On the basis of this signal, the visitor's unit can recognise the object in front of which the visitor is standing and can thus select the associated information.

Patent DE-4342069-A1 (DE)
Title: Position detector for machine tool rotation counter
IPC: G01P3/487
Filed: 1993-12-09
Abstract: The position detector provides an electrical pulse fed to an electronic evaluation stage (1), when a movable component (1), e.g. a rotary shaft, is in a given position. An energy store (85) stores part of the movement energy of the component as potential energy when the component approaches the given position and releases the stored energy as kinetic energy upon it reaching this position. The released kinetic energy is converted into electrical energy by a movable permanent magnet (81), and E-shaped core (84) and an induction coil (88), to provide the output pulse delivered to the evaluation state.
