Abstract: The distributor has a frame with coupling elements for three-point mounting on the lower links and the upper link of a tractor, a funnel- shaped container fastened in the frame and having at least one outflow orifice, and a distributor device drivable by the tractor take-off shaft and located at each outflow orifice. It is characterised in that the upper part of the rear wall of the container is made shovel-like and the container can be tilted out of its operating position rearwards into its shovelling position about an axis transverse relative to the direction of travel. The machine can be filled with the least possible labour in the least possible time without additional devices. The removal of residual quantities of material from the container is also possible in a simple way.

Filed: 1986-09-10
Granted: 1988-08-25
Abstract: A device for removing waste material screened or filtered out of liquid flowing through a channel (1) has a basket-type interceptor (6) that is slanted and cylindrical and that rotates subject to power, extends to some extent into the liquid, and has its upstream face (8) open and its downstream face (9) solid. A conveyor (13) is positioned coaxially in relation to the interceptor, leads to a waste-material deposit point outside the liquid, accommodates a powered conveyor screw (18), and has an intake scoop (15) in the vicinity of the interceptor for collecting the waste material. A mechanism positioned stationary above the intake scoop releases waste material from the interceptor. The interceptor consists of a number of continuous annular disks (8) distributed along the outer surface with gaps between them and the waste-material releasing mechanism is a raker-stripper (28) that at least to some extent extends through the gaps between the annular disks.

Granted: 1990-05-10
Abstract: The work or office chair has a seat support (25), which is swivellable about a horizontal swivel axis in the front region and is adjustable in inclination, with a seat (26) and has a backrest support (18), which is inevitably overproportionally adjustable in inclination in dependence on the change in inclination of the seat support (25), with a backrest (19). With increasing inclination of the seat support (25), the backrest (19) executes an additional relative movement downwards in relation to the facing end of the seat support (25). A chair with overproportional synchronous adjustment of seat and backrest and additional adjustment of the backrest in relation to the seat in the case of change in its inclination is achieved with a simple, operationally reliable adjusting device in that the backrest support (18) is attached (16, 21) at least to one connecting rod which itself is mounted rotatably on the chair frame near to the swivel axis (13) of the seat support (25), in that the connecting rod (16, 21) bears a carrier (23) on the chair frame between the attachment axis (17) of the backrest support (18) and the axis of rotation (15), which carrier is guided adjustably in a guide slot (24) of the seat support (25), and in that the backrest support (18) is preferably connected in an articulated manner on both sides via its attachment axis (17) to a swivel lever (32, 34) in each case, which is mounted swivellably likewise on the chair frame in the region of the swivel axis (13) of the seat support (25).
Patent DE-3932618-C2 (DE)
IPC: G01L9/02
Filed: 1989-09-29
Granted: 1991-07-18
Abstract: Described is a device, produced using micromechanical techniques, for the measurement of mechanical forces and their dynamic effects. Such devices consist of several elements, such as housing, support structure and sensor, which are bonded or cemented together. Not only stresses caused by differences between the properties of the materials used, but also stresses caused by the way in which the elements are joined together, are transmitted to the sensor and limit the accuracy of the measurement device. The device of the invention is characterized by the fact that the support structure and/or the sensor have weak points to avoid the formation of mechanical stresses. The device is inexpensive to produce and suitable for use in the automobile and household-appliance industries, as well as in industrial measurement instruments.
