IPC: B01J8/14
Filed: 1988-12-02
Abstract: The invention relates to a process and apparatus for applying matter to expanded starch-containing products, it being possible to use the process in the foodstuffs industry. The process according to the invention can be used, in particular, in the preparation of starch-containing products known as snacks for applying spices or other matter. The expanded starch-containing product is, immediately after expansion, placed in a reaction chamber where it is exposed to the earth's gravity or a centrifugal field. During this, a gas/vapour mixture flows into the reaction chamber at a high velocity approximately at right-angles to the direction of action of the field. The matter to be applied to the surface of the expanded starch-containing product is introduced together with the gas/vapour mixture into the reaction chamber. In the expansion chamber a velocity component opposite to the direction of the field is imposed on the gas/vapour flow.

Patent DE-3902230-A1 (DE)
Title: Device for fastening an electrical module on a base part
Inventor: HABERSTROH RUDOLF
IPC: H05K5/00
Filed: 1989-01-26
Abstract: A device is proposed for fastening an electrical module on a base part, which device allows both a multipole electrical connection and a mechanical connection to be produced between an electrical module and a base part by one simple operation. The device requires less operating space to be kept free for connection and release of the module and thus allows the arrangement of a large number of corresponding modules in a small space. Damage resulting from contact elements which do not mate correctly is prevented by previously locking the module to the base part, this locking being possible only in the event of a sufficiently accurate contact between the module and the base part; this situation can easily be sensed by touch. High contact insertion forces are developed from the torque of an element which can be operated in rotation. The device has no loose parts which could be lost.

Title: Textile machine drive - applies braking to high inertia units when other units are disengaged
Inventor: MEYER URS DR
IPC: D01H1/32
Filed: 1989-04-10
Abstract: In a textile machine, such as a ring spinner, where at least one drive system operates a number of units with different inertias, at least some of the units (20',30') are disengaged from their drives (20-36) when their speeds are reduced to a preset min. speed. At least the unit (16') with the largest effective inertia is braked according to the disengagement time of the units (20',30'). A braking action is applied to the unit (16') with the largest inertia, at least at about the time that the operating sections (20',30') are disengaged, while remaining coupled to its drive (16) and can be fixed in a preset end position after braking and until it stops. The drives (16-36) for the units (16'-20',30') are speed controlled motors with a supply frequency. The greatest inertia is at the spindles (16') with drawing units (20',30') which can be disengaged from their drives (20-36) at the same time. The drive (16) for the spindles (16') has at least one other drive with a generator-driven motor in the event of a power failure. The drive system (12,14) has separate drives (16-36) for the operating units (16'-20',30') with an electronic control (40) to regulate the speeds and the speed ratios between them, together with a run-down control in the event of a power failure to bring them down into a low speed operating mode, partic. the drawing units (20',30') and the ring rail (18'), and then disengaged at least from the drawing units (20',30'). At least one unit (60) with a high inertia is coupled to its drive motor (20) through a clutch (62) with a toothed belt gearing in the transmission between the unit (60) and motor (20), together with a cogwheel gearing (58), while the toothed belt is between the cogwheel gearing (58) and motor (20), so that the transmission chain for the supply cylinder (60) runs from the motor (20) to the toothed belt, a clutch (62), a brake (64), the cogwheel gearing to the cylinder.
