  • Patent number: 11489405
    Abstract: A gear system includes a gear unit and an electromagnetically actuable brake, the brake having a coil core that is connected to a brake surface part in a torsion-resistant manner. The brake surface part is connected to a bearing flange, its bearing mount in particular delimiting a free space. The bearing flange is connected to a cover part which is connected to a housing part of the gear unit, and a shaft is supported in the housing part via at least one bearing. A driver is connected to the shaft in a torsion-resistant manner, the driver having an external tooth system that is in engagement with an internal tooth system of a brake pad carrier such that the brake pad carrier is connected to the shaft in a torsion-resistant yet axially displaceable manner. An armature disk, which is disposed in a torsion-resistant yet axially displaceable manner with respect to the coil core, is situated between the coil core and the brake pad carrier.

  • Patent number: 5957153
    Abstract: A proportioning pumping system that injects an injection fluid into a pressurized conduit flowing with a working fluid at a constant proportion of injection fluid to working fluid regardless of changes in flow rate or pressure within the working fluid conduit. Injection fluid is pumped continuously, by the working fluid, from a non-pressurized tank. The system includes two or more vessels, each divided into two chambers by a diaphragm or bladder. Valving and passages simultaneously fill one vessel with working fluid and pump injection fluid while filling the other vessel with injection fluid and draining working fluid. A first pressure differential creating device in the working fluid conduit draws injection fluid into the working fluid conduit. A second pressure differential creating device determines the proportion of working fluid and injection fluid to be combined.

  • Patent number: 5473967
    Abstract: Potatoes are conveyed one at a time along a predetermined path ending at a cutter that cuts the potatoes into helical strips. A series of four rings surrounds the path. Each ring has a plurality of nozzles that produce jets of water intersecting at a point in the path. At the outlet of the series of four rings is an orienter through which the potatoes pass. The rings and the orienter align and guide the potatoes as they move along the path and through the cutter.
