The invention relates to a suspension arm 2 with an air guide 1, wherein the suspension arm 2 has in the installation position a downwardly open cross-sectional profile with a base surface 7 and at least two side webs 8 projecting from the base surface 7, and wherein the air guide 1 has a reinforcement element 3 to be arranged on the side webs 8 and an air guiding element 4 composed of a plastic material, and the invention further includes a method for producing an air guide 1 for a suspension arm 2.

The invention discloses a pedaled book page turner. The pedaled book page turner comprises a tabletop, and is characterized in that two opposite slide groove rails are arranged on the tabletop; paired slide blocks are arranged in the two opposite slide groove rails; a page-turning line is connected between every pair of slide blocks; a long execution rod which swings left and right is hinged on a pedestal on the lower parts of table legs; a short execution rod is hinged with the upper end of the long execution rod and penetrates through a long groove hole of the tabletop; a hook is hinged to the upper end of the short execution rod and slides in slide grooves in the front side and the back side of the tabletop; a foot rest lever is hinged on another pedestal below the tabletop; the left end of the foot rest lever is a pedal part; a reset counterweight is arranged at the right end of the foot rest lever; the foot rest lever is hinged with a power swing rod; the power swing rod is hinged with a connecting rod; the connecting rod is fixedly connected with a driving rod through a rotating shaft; the rotating shaft is arranged on a fixing base; the other end of the driving rod is connected with a shifting rod; the shifting rod is positioned in a long groove in the long execution rod; and a thread releasing device is fixedly arranged on the right side of the tabletop. The pedaled book page turner has the beneficial effects that books with any size sold in the market can be turned; and a special power source is not required, the turner is operated by a human foot and is simple and convenient to operate, continuous page turning can be realized, and the addition weight is light.

A method for anti-buckling and reinforcing by a fiber-reinforced composite belongs to the technical field of metal component anti buckling and reinforcing and is characterized in that the method comprises the following three different and independent reinforcing methods of: filling solid light materials, fiber-reinforced composite profiles and wrapping fiber cloth for reinforcement; filling the solid light material; subsequently wrapping the fiber cloth for reinforcement; fully sheathing the fiber-reinforced composite sleeve on the reinforced component and filling the solid light material subsequently; and reinforcing the component by wrapping the fiber cloth. The reinforcing method is flexible, convenient, fast and safe, has small effects on the structure, has light additional weight, obviously improves the bearing capability, and can be combined with other reinforcing types.

The invention discloses a magnetic fluid coupling type passive suspension axial-flow blood pump which comprises a pump casing and a rotor, wherein the cavity in the pump casing gradually widens firstly and then gradually narrows in the direction from the pump inlet to the pump outlet; suspension permanent magnetic rings are arranged inside the upper half section of the pump casing; electromagnetic coils are arranged inside the lower half section of the pump casing; the rotor is arranged inside the cavity; suspension permanent magnetic rings are arranged inside the upper half section of the rotor, driving permanent magnetic rings are arranged inside the lower half section of the rotor, and a drainage groove is formed in the outer surface of the rotor; flow guiding supporting rings are arranged at the pump inlet and the pump outlet, and when the pump casing is filled with blood, the fixed flow guiding supporting rings support the rotating rotor. According to the invention, the magnetic fluid coupling type passive suspension bearing structure with the combined action of permanent magnetic suspension and hydraulic suspension is adopted, so that factors such as abrasion and frictional heating for inducing thrombus are avoided; the passive suspension manner is adopted, so that the energy consumption is less than that of an active control suspension bearing; therefore, the additional weight of the blood pump is effectively reduced, the development of the blood pump towards light-weight type and mini-type is facilitated.

The invention relates to a vehicle structure for a vehicle having a tensioning device adjacent the inner side of the skin of the structure, wherein the tensioning device can be adjusted between different tensioning states by means of a controllable actuator.

Movable modular external AC charger and AC charging system for high-voltage batteries of electric or hybrid motor vehicles. A portable modular external AC charger and an AC charging system for a high-voltage battery of an electric or hybrid motor vehicle, may allow charging performance and range of functions to be adapted as desired.

Fall-back prevention press of a crane in the form of a gas pressure cylinder, with a piston rod engaging in a cylinder space of the gas pressure cylinder configured as piston-type accumulator, with gas in the bottom space of the cylinder being in exchange with the gas in the piston rod and the ring space in surrounding relationship to the piston rod. A seal arrangement in a rod guide of the cylinder seals the piston rod against the cylinder. The seal arrangement includes a lubricant groove which extends around the rod guide and via which the piston rod is lubricated on the outside. The lubricant is acted upon by gas pressure prevailing in the cylinder with interposition of a pressure transmitter.
