Title: Solar-heated cooking apparatus
Inventor: FIEBACK KLAUS DR
IPC: F24S23/00
Filed: 1993-03-17
Abstract: The invention relates to an arrangement for a solar-heated cooking apparatus, with a radiation receiver (1), with a radiation converter (2) and a preferably metallic cooking plate (6). In order to achieve a simply constructed, but efficient solar-heated cooking apparatus, the invention proposes that the heat obtained from the solar radiation be transported from the radiation converter (2) to the cooking plate (6) by means of thermal conduction, a plurality of heat-transporting elements (5) extending in each case from the region of the radiation converter (2) into the region of the cooking plate (6). <IMAGE>
Patent DE-4312649-A1 (DE)
Title: Combined sail control for jib and main sail of sailing vessels
Inventor: KLOSS GERNOT
IPC: B63H9/06
Filed: 1993-04-19
Abstract: The advantage achieved with the invention lies in particular in the fact that the control beam puts both sails into any desired sailing position simultaneously by simple turning about its vertical axis. Since the articulation of the sails can be effected by the control beam in the entire turning range of 360 DEG , it is even possible to sail astern in a side wind. High manoeuvrability is achieved through this extreme steering range, paired with the simple operation of the control. Only one person is required for operating the sail control. A further important advantage achieved with the invention lies in the fact that the main sail does not need a boom due to the guidance via mast stay and control shroud. Thus there is no longer a constant risk of injury to the boat occupants due to a flapping boom. So that sails of different size can also be used, the pivot pins to which the control shrouds are fastened, according to a further advantage of the invention, are mounted so as to be extendable in both ends of the control beam.

Title: Process for the production of building elements from natural fibres and the permanent design of building facades and surfaces of supporting structures as well as elements for this purpose
Inventor: THUMANN WOLFGANG
IPC: E04B1/74
Filed: 1993-05-14
Abstract: The invention relates to processes for the production of building elements from natural fibres and the permanent design of building facades and surfaces of supporting structures as well as elements for this purpose. The use of organic fibre material also as surface cladding is gaining increasing importance in ecologically oriented building. The known building elements and claddings for designing building facades and surfaces of supporting structures, such as coated glass walls or rock walls and synthetic foams as well as plastics in general and also metals, have for some time no longer been considered uncritically. The ecologically and economically unjustifiable high energy consumptions for the production of design elements and claddings, particularly when these are at the same time to perform heat-insulating and sound-proofing functions, and the problems of disposal, particularly of building elements containing plastic, have prompted environmentally conscious building contractors to seek alternative claddings and surface designs consisting of natural fibres, particularly those which are suitable at the same time as insulating materials. This is achieved, according to the invention, in that for the permanent heat-insulating and sound-proofing cladding and design of surfaces of supporting structures and building facades as well as for binding harmful substances, animal wool in highly compacted webs ... according to the invention with low-compacted webs or strips of soft wool fleece with ...

Patent DE-4325454-A1 (DE)
Title: Rotary combustion engine with separate compressor and compressed air reservoir functioning virtually continuously
Inventor: LIPINSKI JOSEF
IPC: F01C11/00
Filed: 1993-07-29
Abstract: In addition to simple construction, the engine offers fuel savings and virtually noise-free and vibration-free running. Engine and compressor are of similar construction and are seated on a common main shaft in separate housings. There are no reciprocating parts. Opposing discs, which roll on their end faces are arranged on the main disc. For improved sealing the end faces are provided with a very low toothing. The main discs are formed as a U-profile on the end face and have tooth-shaped webs. The opposing discs run in the said U-profiles and have tooth gaps which roll over the webs without making contact. The working chambers are formed by the said U-profiles, the outer housing and the webs and opposing discs. The compressor draws air in continuously by way of a valveless opening and forces it into the compressed air reservoir. From there the compressed air passes into the combustion chambers, which are situated outside the engine and are controlled by two discs, which are rotated by the main shaft. In addition to the fuel injection and ignition, the combustion chambers are scavenged. The highly compressed gases pass by way of the side wall of the U-profile into the working disc, causing it to rotate and expanding in the process. The expanded gas is expelled by way of a valveless opening.

Title: Gas-burner combination and method for its ignition
Inventor: GROFE FRANK
IPC: F23D14/12
Filed: 1993-08-24
Abstract: The invention describes a gas-burner combination and a method for its ignition, a hyperstoichiometrically premixing burner with a flame outlet surface of perforated ceramic being ignited by a likewise hyperstoichiometrically premixing pilot burner integrated into the radiant main burner. The pilot burner itself is ignited, in a known manner, piezoelectrically, with battery ignition or the like. The radiant main burner and pilot burner utilise the same perforated ceramic plate as flame outlet surface and form a constructional and functional unit. In a burner described as an exemplary embodiment, the distribution space 3 of the pilot burner I is integrated into the distribution space 6 of the radiant main burner II. The mixing tube 2 of the pilot burner I is screwed into the distribution space 3 of the pilot burner I through the wall of the distribution space 6 of the radiant main burner II. The flame outlet surface 7a is adhesively bonded into the distribution space 6 of the radiant main burner II by means of silicone adhesive. The sealing between the distribution space 3 of the pilot burner I and flame outlet surface 7a is likewise effected by means of silicone adhesive, thereby at the same time guaranteeing a gastight separation of radiant main burner II and pilot burner I. <IMAGE>

Title: Control of car body inclination
Inventor: DRUECKE PETER DR ING
IPC: B61F5/22
Filed: 1994-05-11
Abstract: A procedure for controlling the inclination of a car body has the angular speed about the longitudinal axis, the vertical axis and the transverse axis measured, as is also the longitudinal car speed. The three angular speeds in the car's reference coordinate frame are transformed to values in a stationary Cartesian frame and then angles in the three directions are deduced by integration wrt time. Acceleration components in the stationary frame are also deduced from measured accelerations in the car's reference frame. The control philosophy combines proportions of these accelerations with values of the angular speeds in the stationary frame.
Patent DE-4418793-A1 (DE)
Title: Induction motor control method
Inventor: ENDRIKAT CHRISTIAN DR ING
IPC: H02P21/06
Filed: 1994-05-25
Abstract: In a procedure for controlling an induction motor fed by a phase-sequence inverter and a DC intermediate circuit, the discrete-time field-oriented control results from sampling and control intervals that are synchronous with the stator frequency. Using a discrete-time flux observer (7) processing the stator variables, the rotor flux is evaluated followed by synchronisation with the actual currents flowing in the motor. To eliminate the commutation effects in the sampling of data, the voltages are sampled 60 electrical degrees after each commutation. By using the flux observer, a discretisation of the relevant differential equations is obtained; equations are given in the text.
