Patent DE-4124720-A1 (DE)
Title: Satellite receiver high frequency signal switch=over device - intercepts polarised HF signals for single or multiple antenna installations by using distribution matrix
Inventor: EPHAN NORBERT DR
IPC: H04H40/90
Filed: 1991-07-25
Abstract: The switch-over device has at least two groups of input terminals (12'12") for receiving two HF signals. Differently polarised waves from different paths can be received in dependence on the control of the user, via a distribution matrix (VM). Either the first or the second HF signal can be seletively received at two outputs (A1,A2). The distribution matrix (VM) has four distribution lines (11) and, each line having an actuable or blockable switch, preferably an IF amplifier (15). These can be switched between "open" and "block" in dependence on a voltage applied via the outputs (A1,A2). The inputs of the two amplifiers are conencted to the first input terminal (12') to receive the first HF signal (H). The inputs of the third and fourth amplifiers (15) are connected to the second input (12") to receive the second signal (V). The amplifier outputs are connected either to the first or second output terminal to receive the required signal. A user-dependent control switch actuates the appropriate amplifiers (15) according to the connection condition of the outputs (A1,A2). USE - For receiving satellite broadcasts and distributing signals terrestrially.

Title: Loose cake decoration dispenser - has handle lever to move slide into filling position for release to give sprung ejection of matter to cake surface
IPC: B65D83/04
Filed: 1992-01-31
Abstract: The dispenser for loose material, such as for cake decoration, etc. with sugar or chocolate or chopped nuts or almonds, etc., has a housing (1) with a holding zone (11) for the material and a connected delivery zone (7) with an ejection opening (8). A slide (14) moves between the filling setting which connects the supply and delivery zones, and an ejection setting which separates the zones from each other.

On reaching the filling station, the slide is automatically released and, when the hand lever is released, it returns to its coupled state. USE/ADVANTAGE - The appts. is used to decorate cakes, etc., where the decoration material is ejected to the cake surface with sufficient force to become embedded. The appts. gives cake decoration rapidly and simply, without loss of material.

Title: Dental prosthesis - is formed part coated on all sides with one or more layers directly and in single operation
Inventor: HAHN RAINER DR
IPC: A61K6/884
Filed: 1992-03-25
Abstract: The formed component (3) for dental prosthesis is coated (2) on all sides, with at least one or more layers of organic, inorganic or metal materials and/or a suitable combination of these materials. Pref. materials are filled and/or unfilled and/or fibre-reinforced plastics, organic or inorganic composites, ceramics, carbon materials such as graphite or CFC materials and/or metals and/or metal alloys or the initial stages of these materials. The formed component (3) can either be built up on a positive model (1) by deposition, pressing into place or coasting, and the hardened and/or converted by chemical-physical action. Or it can be a substractive operation from raw material or a semi-finished workpiece. The chemical-physical action to convert the initial materials can be a cross linking reaction and/or sintering carbonising process, carried out after surface coating of the formed component or after the prosthesis is finished, so that each component can be prefabricated with or without a coating. The formed part (3) remains in the cpd. structure, also after coating (2), with the required three-dimensional geometry. USE-ADVANTAGE - The dental prosthesis can be coated directly and on all sides such as a dental plate, with precision in a single operation with a choice of materials to give the required strength in a thin structure. Where gold is used, only a thin layer is required which reduces gold usage, with reduced weight and material costs.

Title: Roasting of microwave oven - has a display to show remains cooking time and time when final core temp. will be achieved
Inventor: KRUEMPELMANN THOMAS DR
IPC: F24C7/08
Filed: 1992-05-30
Abstract: Roasting oven or microwave oven, with a thermal probe to determine the temp. of the food to be cooked and a heating control and monitoring circuit, has a display to indicate the temp. control operation for cooking as set by the computer circuit according to the measured core temp. during cooking, to give the computed remaining cooking time and the time when the final core temp. will be achieved. The computer circuit can determine the time intervals needed for a given core temp. interval. The measured value pairs, for time and core temp. intervals, are stored in memory for comparison to give the remaining cooking time. The remaining cooking time is continuously renewed for display of the actual computed time to achieve the final core temp. The core temp. interval has a fixed lower limit, and the upper limit is formed by the actual core temp. value. The lower limit for the core temp. interval is more than 300 deg. C. and the min. interval value is 10K. The core temp. interval has a fixed length, and the upper interval limit is affected by the actual measured core temp. The remaining cooking time is computed arithmetically from the core temp. interval calculations. USE/ADVANTAGE - The oven control is for the cooking time to be set and operated for correct cooking. The system gives the user information on the cooking time remaining when the oven is working.
