Patent DE-3143344-A1 (DE)
Title: Adjustable bearing preload
Inventor: WEHRFRITZ HEINZ DIPL ING
IPC: H02K7/08
Filed: 1981-10-31
Abstract: The static and dynamic behaviour and service life of spindles is determined to a substantial extent by the preload on their bearings. In the known designs, it is not possible to match the bearing preloads optimally and in a simple manner to the particular application. In a new design, a bush which is set by means of springs and accommodates the floating bearing is additionally supplied with compressed air, the springs ensuring a minimum preload while the compressed air is used to set the optimum preload for the machining task. The spindle comprises a housing (1), in which a bush (9) accommodating the floating bearing (8) is arranged in a manner which allows displacement. The springs (16) subject the bearing to the minimum preload to ensure functional reliability. The bush (9), which is designed as an annular piston, is supplied with compressed air via a system (12) of channels. The air pressure and hence the axial force can be controlled by means of a pressure control valve. <IMAGE>

Patent DE-3152831-A1 (DE)
Title: Corner connector
Inventor: BAUS HEINZ GEORG
IPC: A47K3/34
Filed: 1981-11-27
Abstract: The invention relates to a corner connector for two frame profiles, in particular a door segment of a partition wall for showers or bath tubs, having two outer surfaces preferably enclosing a right angle, each of which is abutted by a face of the frame profile. A corner connector of this type also has holes in the area of the said outer surfaces, which holes are in each case flush with a screw channel of the associated frame profile. Previously it was relatively expensive to assemble a frame with corner connectors and frame profiles, particularly since often particular care and processing accuracy were required to achieve a symmetrical and stress-free connection. Finally there were further difficulties if the door segment was to be suspended for example by means of rollers or the like on a guide rail via the corner connector, particularly since production of the corner connector itself required form tools which were of quite complex design. It is therefore proposed according to the invention that the corner connector has an internal cavity, and that an orifice is provided in the corner connector opposite the face of one preferably vertically aligned frame profile, through which orifice an insert element projecting into the cavity is inserted. The said insert element also has a longitudinal hole flush with the screw channel of the other frame profile, through which hole a screw is introduced into the said screw channel. <IMAGE>

Patent DE-3202463-A1 (DE)
Title: Device for feeding experimental animals
Inventor: KIEPER JOACHIM
IPC: A01K1/035
Filed: 1982-01-27
Abstract: These devices can be used in experimental veterinary medicine in universities, research institutes and the pharmaceutical industry. These devices are suitable for refitting of available standard animal cages, especially on the wire lid of these animal cages. The feeding devices, by means of which the time, duration and frequency of the supply of food to experimental animals can be predetermined and established are designed in three versions. One model has a feeding basket whose contours match those of the standard cage lid, and can be lifted and lowered, and it thus controls access to the food for the experimental animals. This construction is suitable for food pellets which have a diameter or edge length above 10 mm. In the embodiment with the flexible woven wire closure the same food pellets are placed in the available rack in the wire lid. The closure at the bottom of the rack prevents or permits access of the experimental animals to the food. Depending on the position of the mobile feeding trough, access of the animals to the food meal from the rack closed like a container is in each case permitted or prevented. The feeding technique for rats, mice, hamsters, gerbils, guinea pigs, etc. possible with the devices described permits time-controlled food consumption by these experimental animals. In animal experiments on rodents feeding has hitherto been ad libitum, i.e. it has depended on the animals how often and how much they eat from the food which is always available. The feeding devices now permit controlled food consumption with due consideration of aspects of diurnal rhythm. <IMAGE>

Patent DE-3208678-A1 (DE)
Inventor: BUSCH DIETER ING GRAD
IPC: H04R11/00
Filed: 1982-03-10
Abstract: An electro-acoustical transmitter converts electrical signals which correspond to acoustical events into mechanical vibrations which are transmitted onto the skin. The aim is to achieve a small vibrator which, insofar as possible, can be worn on the wrist, for instance, in the manner of a wristwatch. To that end, a coil is employed into which a magnetic core, resiliently mounted relative thereto for instance by a diaphragm, projects as an armature. The housing which carries both the diaphragm and the coil forms the magnetic return flux path. Thus, a miniaturization of the vibrator on the desired order is achieved. An inventive vibrator is particularly suited for the deaf.
