Title: Method of producing plastic-coated model cast prostheses and orthodontic appliances
IPC: A61C13/00
Filed: 1986-06-18
Abstract: The proposal according to the invention - method of producing plastic-coated metal cast prostheses and orthodontic appliances - is concerned with novel coating methods that have hitherto been uncustomary for dental prostheses and in orthodontics. A number of disadvantages such as mechanical wear due to friction between braces and tooth surface is greatly reduced. Tissue-compatible plastics avoid metal allergies and compensation currents which may flow between dental fillings and crowns, on the one hand, and the metallic part of the model cast prosthesis, on the other hand. The essence of the novel production method for thin, wear-resistant, tooth-saving plastic coatings proposed by the invention resides in the introduction of the heating effect of current by means of high-frequency electromagnetic fields in order to permit polymerisation or curing of thin plastic layers by short-term heating. The particularly high strength and wear resistance of these layers is obtained, in particular, in that polymerisation starts from the metal/plastic boundary layer and continues outwards. The above-mentioned boundary layer always has the highest temperature during this process. Since heating is very short-term and, in addition, it can be introduced partially into the metallic part of the prosthesis, heat damage of the plastic embedding compositions or the artificial teeth is ...

Title: Passenger or estate car
Inventor: PRANTL JOSEF
IPC: B60K11/08
Filed: 1987-01-22
Abstract: The application relates to a passenger or estate car with internal combustion engine arranged in the front of the vehicle and mudguards laterally defining the outline of the vehicle. The intention was to find a way of ensuring a favourable air intake for the internal combustion engine of the vehicle even in the case of vehicle bodies of aerodynamic design, which in the front end area have virtually only one opening for admission to the radiator. According to the invention, this is achieved in that the outer skin of at least one mudguard has at least one opening in its approximately vertical lateral area in a largely neutral air pressure zone, which opening is connected by means of a flexible line to an air filter of the internal combustion engine.

Patent DE-3732790-A1 (DE)
Inventor: RILLY GERARD DR ING
IPC: H02M3/335
Filed: 1987-09-29
Abstract: In a switched mode power supply, an output switch is coupled to the primary winding of a transformer and to an input supply voltage derived from the AC mains voltage. A driver stage is coupled to the output switch and to a switched control voltage for producing on-off switching of the output switch between conduction and cutoff to generate a pulse voltage in a secondary winding of the transformer. A supply circuit including a rectifier is coupled to the pulse voltage for generating an operating voltage. A control circuit, responsive to the feedback of the output voltage, modulates the control voltage in a manner that varies the on-off switching of the output switch to stabilize the operating voltage. A bias voltage, derived from the AC mains voltage, and available during a startup interval of the power supply, is coupled to the driver stage during the startup interval. The bias voltage inhibits conduction of the output switch until sufficient time has elapsed after initiation of startup to enable the control circuit to generate a control voltage that is adequate to safely produce the on-off switching of the output switch.
