Date Nov. 25, 1982.An apparatus for transferring a pulverulent material from a storage area to a destination site comprises a screw conveyor for transporting the material. The screw conveyor has an inlet and an outlet for the material. A filter surrounds the conveyor at least at the outlet of the conveyor and allows the passage essentially only of air therethrough. A damper at the outlet of the conveyor controls the flow of material from the outlet, and a damper is operative to be opened by the material transported by the screw conveyor. The filter comprises a filter sheet in the form of a circular drum having an inner side and a multiplicity of frusto-conical rings. The rings are disposed on the inner side of the drum and directed with their ends of smaller diameter in a direction towards the damper. The apparatus is useful for filling packages with finely pulverized materials, such as kaolin clay, lime and starch.

Abstract: Filler particles are coated with an adduct of an unsaturated polymer, e.g. polybutadiene, and phosphinic acid groups. The coated filler may be prepared by reacting an unsaturated organic polymer with a phosphorus trihalide and applying the product in the form of a solution or dispersion in an organic solvent to mineral, e.g. calcium carbonate, particles. If liquid, the product may alternatively be applied as such to the mineral particles. In either case, the product so applied is then hydrolysed in situ in order to form the phosphinic acid groups. The coated filler particles are useful in the reinforcement of elastomers.

Abstract: In an electrolytic reduction cell in which molten metal is produced by electrolysis of a molten electrolyte, less dense than the molten metal product, the molten product metal collects at the bottom of the cell. A filter is provided at this location and is constructed from a material which is resistant to attack by both the molten metal and molten electrolyte, and which is wetted by the molten metal, but not by the electrolyte. By correct sizing of the passage or passages in the filter molten metal product can be drawn out of the cell without simultaneous withdrawal of molten electrolyte. In the case of a cell for the production of aluminium the filter is preferably constructed from titanium diboride.

Granted: 1994-01-04
Abstract: ABSTRACT OF THE DISCLOSURE     In a feed-forward amplifier which has an error detection circuit for detecting a nonlinear distortion component of a main amplifier and an error rejection circuit for amplifying the detected distortion component by an auxiliary amplifier and injecting it into the main amplifier to thereby cancel an error component, a first pilot signal is injected into a signal input path and a second pilot signal is injected into a signal amplification path of the error detection circuit.  A first variable attenuator and a first variable phase shifter of the error detection circuit are adjusted by a control circuit so that the level of the first pilot signal component on an error injection path of the error rejection circuit decreases to minimum.  A second variable attenuator and a second variable phase shifter of the error rejection circuit are adjusted by the control circuit so that the level of the second pilot signal component on a signal output path decreases to a minimum.  The first pilot signal component which appears on the signal output path is rejected by inserting therein a filter or cancelled by supplying the error injection path or signal output path with the first pilot signal after adjusting its amplitude and phase. Alternatively, the frequency of the first pilot signal to be injected into the signal input path is spread to thereby lower the level of the first pilot signal per unit spectrum which appears on the signal output path.

Title: Core assembly for pneumatic tire
Inventor: ITO SHUNGO
IPC: B60C17/04
Filed: 1991-07-22
Granted: 1998-01-06
Abstract: A core assembly for a pneumatic tire, which is fitted annularly to an outer peripheral surface of a well portion of a rim, and which rotates should the pneumatic tire collapse owing to a decline in its internal pressure, as an outer surface of the core assembly comes into contact with an inner peripheral surface of a crown portion of the pneumatic tire and an inner peripheral surface of the core assembly slides over the outer peripheral surface of the well portion of the rim.  The core assembly includes a sliding portion formed of a resin material having good sliding properties and high heat resistance, and a main body to which the sliding member is secured and which is formed of a material having a high rigidity and a low specific gravity.  Accordingly, since the surface of the core assembly contacting the rim is constituted by the sliding member, the core assembly is rotated smoothly when the internal pressure of the pneumatic tire declines, and the overall weight of the core assembly is reduced.
