Abstract: A motor vehicle speed regulating device having a desired speed setting device, an actual speed detecting device, and an acceleration controlling device which operates to regulate the rate of acceleration upon changes made in the adjustment of the set speed device, wherein a delay device is connected in a feedback between a speed correcting device and the acceleration control device.

Abstract: A blending chamber silo for pulverized bulk material has a main silo chamber with an inlet in its uppermost region, and a centrally located blending chamber on the floor of the silo has a roof and side walls with bottom apertures therein for the influx of the material from the main silo chamber into it. Aeration apparatus and air inlets are provided for the silo floor, and separate homogenization aeration apparatus is provided for the floor of the blending chamber, which operates under a pressure higher than that of the silo aeration apparatus. The roof of the blending chamber is spaced well below the top of the silo, and the blending chamber has a diameter substantially smaller than the diameter of the silo, whereby the lower portion of the silo wall and the wall of the blending chamber define a semi-annular narrow space having a height to width ratio greater than 1:1 and which breaks up material compacted or formed into bridges in its downward path toward the bottom apertures of the chamber.

Abstract: An overload protection device for a top pan precision scale having a weighing pan support and a support plate carried by a load support mounted for limited movement and connected to an indicator, includes a spring engaged between the weighing pan support and the support plate whereby the weighing pan support is resiliently coupled to the load support, and a plurality of overlapping elements carried by the weighing pan support and extending beyond the outer peripheral edge of the support plate in close proximity thereto so that the weighing pan support and support plate are held in assembled relationship against the bias of the spring by the overlapping elements at the outer peripheral edge of the support plate, whereby upon eccentric loading of the scale, the pivot point of the weighing pan support is extended to the side of the weighing pan support opposite the load, and the lever translation thus effected results in a lower load on the load support than the highest available load.

Abstract: An upright storage silo for fluid materials, such as comminuted, powdered and granulated livestock feed, flour, grain, spices, sugar, cement, fertilizer and similar, has a mixing chamber centrally located within the silo; a discharge chamber within the silo in communication with the mixing chamber, and defining an area separate from the silo interior; a plurality of aeration orifices within the floor of the silo; a lifting tank in conduit connection with the mixing chamber and discharge chamber; a shut-off mechanism, and a dosage mechanism for conveying the material from the silo. Flow control apparatus of the pressure of aeration is employed for lifting, pulverizing and discharge of the material by utilizing the increased discharge pressure of the pulverized material for the lifting thereof. The material rises under the increased pressure in communication with the silo discharge aperture and thereafter the pressure is relaxed.
