Title: Automatic system for the direction of rotation of a gum-massaging brush
Inventor: KLASEN ANTON
IPC: A61C17/26
Filed: 1988-06-06
Abstract: The present device comprises a handle with in-built motor and the switching function 1/2/3 for selection of the speed. The motor has the task of driving a round brush via a shaft. This round brush is covered above the rotating shaft and above one half of the brush. It is achieved thereby that a rotating brush can now be used to clean the teeth and massage the gums. In comparison with conventional tooth brushes (electrical or manual) this has considerable advantages. The massaging effect and the perfusion of the gums are improved. It is easier to maintain the brushing direction "red-white". To ensure the necessary direction of rotation at any time, the direction of rotation is controlled via an automatic switching system. If the user pushes the brush upwards against the teeth the brush rotates counter-clockwise (as seen from the motor). If he pushes it downwards the brush rotates clockwise. The switch is actuated by the movably mounted shaft. The device is at a standstill if there is no pressure on the brush.

Patent DE-3841148-A1 (DE)
Title: Tractor, especially for use in asparagus fields
Inventor: SCHULZE HEILING KLAUS
IPC: B62D49/06
Filed: 1988-12-07
Abstract: In known tractors, coupling devices for mounted appliances are provided on the rear side of the tractor. This results, in the case of many mounted appliances, for example ploughs, in strong influences being exerted on the running direction of the tractor which lead to inaccurate working results. In the new tractor, the influence of mounted appliances on the running properties is to be reduced. The new tractor is characterised in that the chassis (12, 12') is designed in the form of stilts, with the vehicle frame (10) together with drive unit (11) and vehicle driver's position (15) being placed higher, and in that the coupling devices (2) for the additional appliances are arranged underneath the vehicle frame (10) between the front and rear wheels (13, 14) of the tractor (1). Advantageously, as a result of the high ground clearance of the new tractor, the mounted appliances can be attached underneath the vehicle frame between the front wheels and rear wheels. This results in substantially more favourable force conditions between the tractor and the mounted appliance, thus leading to improved running properties of the tractor and improved working results. The new tractor is particularly suitable for use in agricultural cultivations requiring earth embankments, for example in asparagus cultivation. <IMAGE>

Abstract: The invention is based on the object of designing a mixing housing having a spherical inlet nozzle (9) rotatably mounted in a front covering member (7), in such a way that the air and water supply lines (19, 32) are protected against penetration of bath water when the whirlpool system is not used, and that cleaning of these lines is possible by a rinsing method without rinsing liquid passing into the tub. A piston (15) whose front termination disc (23) is provided with an injector (24) is slideably mounted in the housing. The injector opens into a mixing chamber (26) and under water pressure is passed through it into the mixing chamber. The piston is supported by its front face against a cylindrical helical spring whose other end rests against the inside of the covering member (7). Provided that the rear side of the piston is not exposed to under water pressure from the line (32) the spring forces a sealing ring (27) located in the rear region of the injector (24) on to a pin (27a) that is fixed on the housing, so that the interior space (25) of the piston is sealed relative to the mixing chamber. Furthermore, the air-conveying annular channel (15) which is exposed to compressed air from line (19) is also sealed relative to the mixing chamber (26). The subject of the application is used in the sanitary field. <IMAGE>
