Patent DE-3436797-A1 (DE)
Title: Valve for inflatable boats (plastic-sheet boats)
Inventor: SCHEFFER WALTER
IPC: B63B7/08
Filed: 1984-10-06
Abstract: The valve consists of a connection piece (10) which is inserted into a hole in the boat skin and is connected to the boat skin, a stopper (30) which is screwed into the connection piece, and a cap (40) which is screwed onto the stopper. When inflating the inflatable boat, the cap is unscrewed and the head part of the air pump is inserted into the cylindrical space of the stopper. During pumping, the air enters via apertures in the base of the stopper, the return flow of the air being prevented by a rubber diaphragm (38). The cap is designed in such a way that it extends due to its frustoconical shape almost down to the boat skin so that ropes or the like slide across it and cannot be caught. The thread at the connection piece is formed on a bush (20) which is made of a rigid plastic. It is pressed into a bush (12) made of non-rigid plastic. Integrally formed on this bush is a flange (11) which is used for connecting to the boat skin. The material of the flange permits adhesive bonding, welding or vulcanisation, depending on the nature of the boat skin. <IMAGE>

Title: Method for determining the position of rotation of, and for positioning of, workpieces with relatively non-distinctive features
Inventor: FROESE-PEECK RUEDIGER DIPL ING
IPC: B23Q41/00
Filed: 1984-12-21
Abstract: A freely programmable device for determining the actual position of rotation and establishing the intended position of rotation of workpieces in combination with a programmable handling device or industrial robot with controlled axes. By means of a gripper, the workpiece is picked up at a controlled axis of rotation and held in the region of a fixedly mounted sensor. During the rotation of the workpiece, the desired features pass through the sensor region. By means of a subsequent analysis circuit, the signals from the robot system, indicating the angle of rotation, are processed together with the signals from the sensor. <IMAGE>
Patent DE-3501862-A1 (DE)
Title: Ventilation device for an electrical generator
Inventor: VOGELSBERGER MARCEL
IPC: F01P5/06
Filed: 1985-01-22
Abstract: A ventilation device is used for improving the cooling of an electrical generator (1), especially an alternator, which is connected to an air-cooled thermal engine. The shaft (2) of the generator (1) is driven via a V-belt (5) with the aid of the thermal engine and bears a cooling turbine (4) for said thermal engine. A cooling airflow which flows around the generator (1) and is then passed to the thermal engine is produced by means of the cooling turbine (4). According to the invention, an air-induction cap (12) is mounted on the side of the generator opposite the turbine (4); the cap (12) has an outer part (15) which projects into an annular flow guide (7), which surrounds the generator (1), in order to divert a part of the cooling airflow and supply it to the generator (1) (Fig. 1).

Title: Heating boiler for compressed gas or compressed oil with a pot-shaped combustion chamber provided in an inner ribbed pipe
Inventor: HEIM KURT
IPC: F23M5/00
Filed: 1985-01-26
Abstract: Arranged in the inner ribbed pipe (6) is a pot-shaped combustion chamber (8). The latter has a pot-shaped lining (10) made of ceramic fibres. The lining (10) extends forwards from the combustion chamber bottom and has a length which corresponds to approximately half the length, but at the most to two thirds of the length of the combustion chamber (8). By the region of extension of the lining (10), the smoke gases have given off their greatest heat and have in this region their lowest temperature. A reheating of the smoke gases is then prevented and a low smoke gas temperature is guaranteed by the lining (10). An additional burning out of the smoke gases is achieved by the glowing surface of the lining and thus a high CO2 content of the waste gases, as a result of which the degree of efficiency of the heating boiler is considerably improved. The lining is connected to the combustion chamber bottom which can be moved to the open end of the combustion chamber. <IMAGE>
Patent DE-3508433-A1 (DE)
Title: Boring tool
Inventor: BERNER WILLY
IPC: B23B51/04
Filed: 1985-03-09
Abstract: In a boring tool with one or more radially adjustable cutting-tip holders (2, 3) which are arranged on a head part (1) which can be connected to an adaptor (11), at least one bore (14) is made in the head part (1). The bore (14) starts from the axis of rotation of the head part (1), runs in the direction of the cutting-tip holders (2, 3) to the periphery (15) and leads out there and is connected to a fluid-feed line (12a, 12'). The inclination of the jet bore (14) is selected in such a way that the bore axis (S, S') extended from the axis of rotation beyond the periphery (15) passes through the area of the centre third inside the possible radial settings of the cutting tips (4, 5) to define the cutting zone at the workpiece. The periphery of the head part (1) across the outlet point of the jet bore (14) is bevelled, preferably at an angle in the range of 30 to 60 DEG . In this way, optimum cooling is achieved. <IMAGE>
Patent DE-3514832-A1 (DE)
Title: Device for determining the key of an image transmitter operated in a keyboard
Inventor: MAAS MICHAEL DIPL ING
IPC: G06F3/041
Filed: 1985-04-24
Abstract: The device comprises a transparent pane (6) which is mounted in front of the image area (4) of the image transmitter (2), is a component of a keyboard (7), and can be operated by pressing the key with the force (F). The transparent pane (6) is supported on at least three bearing points (8A to 8D) with respect to the image area (4). At least two bearing points (8A to 8D) are provided with force sensors (10A to 10D). When a keying pressure is exerted on the pane (6), these sensors display these forces (FA to FD) or changes in force prevailing at the bearing points. The force sensors are connected to an evaluation unit (30) which determines from the measured values (FA to FD) the location (xF, yF) of the keying pressure of the force (F) on the pane (6) and emits a corresponding position signal (T1,1 to T3,4) for the operated key of the keyboard (7). <IMAGE>
Patent DE-3535286-A1 (DE)
Title: Torsional vibration absorber for a drive shaft
Inventor: WELZBACHER JUERGEN
IPC: F16F15/12
Filed: 1985-10-03
Abstract: The torsional vibration absorber has a single rotary mass (4), which is secured by means of rubber bodies (5) on a hub (1) that can be connected to a drive shaft. In order to increase the total torsional spring stiffness and hence resonant frequency of the torsional vibration absorber when a certain speed of rotation is exceeded, resilient switching elements (8) are secured on the inner wall (7) of the rotary mass (4) and these rest under prestress on the circumferential surface (6) of the hub (1). The centrifugal forces which arise when the said speed of rotation is reached cause the switching elements (8) to move radially outwards and come into engagement with arms (10) on the hub (1), forming additional torsion springs which act in parallel with the rubber bodies (5). The torsional vibration absorber is therefore suitable for the absorption of undesired vibrations in a number of frequency ranges. <IMAGE>
