The invention relates to a device (10) for suspending a unit (22), especially a hydraulic unit of an electronically slip-controlled brake system of a motor vehicle, in a receptacle (32a, b, c) provided for that purpose on the vehicle such that vibrations are damped. Hydraulic units of vehicle brake systems are usually equipped with an electric motor (26) which drives pumps located in the hydraulic unit. The brake pressure in the wheel brakes can be modulated via said pumps. The pump drive can cause mechanical and hydraulic vibrations in the unit (22) which can result in unwanted operational noise in case said vibrations are transmitted to the vehicle body without being damped. Devices (10) known in prior art for damping such vibrations can be preloaded with the aid of tools.; Disclosed isa manually preloaded device (10) because generally space for using tools is limited in the vehicle. The inventive device (10) comprises a clamping means (16) which is guided in an axially movable manner on an armature (12) that is fixed to the hydraulic unit and which can be moved from a basic position into a clamping position. The clamping means (16) is interlocked with the armature (12) in bothpositions.

The invention discloses a washing type dust removal device capable of pressurizing, filtering and discharging dust in reciprocating manner. The washing type dust removal device comprises a device body, wherein the device body mainly comprises a dust suction region, a buffer region, a filtering region, an air inlet tube, an air outlet tube, a water draining tube and a support frame; a fixed shaft is transversely arranged in the filtering region; a left-right sliding piece sleeves the fixed shaft; a sliding plate fixedly sleeves the sliding piece; the right side of the sliding plate is fixedly connected with a rubber barrel; the buffer region is arranged on the top of the filtering region and positioned inside the device body; the dust suction region is arranged on the top of the buffer region; the bottom of the buffer region is connected with a plurality of dust suction plates; rotary spraying tubes are arranged among the dust suction plates; and a rotating shaft is transversely arranged on the top of the inside of the dust suction region and is connected with a water storage barrel through the sliding piece. The dust removal device is high in dust removal efficiency; high dust removal efficiency can be kept for a long time; the dust removal effect is improved greatly; the device is small in dust removal load and is prevented from being damaged; dust is discharged simply; workload of dust discharge of operators is reduced; and the working efficiency of the workers is improved.

A tap for dispensing fluid from a vessel includes a main tap body, an actuator, and a seal member. The main tap body includes a passage with an inlet and an outlet and a seat with a shoulder formed around the outlet. The actuator has a handled and is pivotally attached to the main tap body and dispenses fluid from the vessel upon activation of the handle by a user. The seal member is received within the seat and attached to the actuator. The seal member includes a retaining portion received against the shoulder of the seat and a sealing portion which is releasably engageable with the seat. The seal member is resilient to provide a bias force to urge the sealing portion against the seat. The actuator is pivotal between a closed position in which the sealing portion is biased against the seat, thereby preventing fluid from passing through the outlet, and an opened position in which at least a portion of the sealing portion is pulled away from the seat against the bias force, thereby allowing fluid to flow through the outlet.

The invention relates to the field of preparation of nanofibers, especially to a preparation method for a spontaneously-heating elastic nanofiber. The preparation method comprises the following steps: subjecting thermoplastic elastomer and cellulose acetate butyrate to blending and drawing for fiber formation so as to obtain an elastic fiber; then removing cellulose acetate butyrate in the elastic fiber through extraction so as to obtain an elastomer nanofiber; then uniformly dispersing the elastomer nanofiber and inorganic heating powder in an organic solvent so as to obtain blended liquid; adding acetone into the blended liquid to allow a polymer to be precipitated; and subjecting the polymer and cellulose acetate butyrate to blending, extrusion and drawing for fiber formation and removing cellulose acetate butyrate through extraction so as to obtain the spontaneously-heating elastic nanofiber. The spontaneously-heating elastic nanofiber prepared by using the method has good elasticity and spontaneous heating performance.
