Systems and methods for reinforcing a pipe. A robot is adapted for rotating in a pipe to apply resin and/or fiber to an inner surface of a pipe in a generally helical pattern. Application of resin and/or fiber to the pipe may be actively adjusted to achieve desired application. A rate at which the robot moves along the pipe per revolution of the robot can be may be adjustable. A rate at which fiber is advanced toward the inner surface of the pipe may be adjustable for application of the fiber to the inner surface of the pipe in a generally non-tensioned state.

The invention discloses a fluid dynamic machine with a rotary wheel piston speed change mechanism. The fluid dynamic machine is composed of a cylinder body (2), a piston (3), a sliding connecting rod (8), a transmission shaft (4), a rotary wheel transmission device (5) and an air distribution device (6), wherein a rotary wheel disc (51 )of the rotary wheel transmission device (5) of the rotary wheel piston speed change mechanism (1) is eccentrically arranged on the shaft body of the transmission shaft (4); a guide shaft (52) on the rotary wheel disc (51) and the sliding connecting rod (8) are linked with each other; the rotary wheel disc (51) rotates eccentrically; a piston (3) does decelerated motion along with the length change of the arm of force between the axis of the guide shaft (52) and that of the transmission shaft (4); under the driving of the sliding connecting rod (8), the piston (3) performs decelerated motion from a lower stop point (20) to an upper stop point (19) and performs accelerated motion from the upper stop point (19) to the lower stop point(20).

The invention discloses a corn kernel threshing and separating device which comprises a threshing roller with threshing teeth. Each threshing tooth comprises a tooth rod with a spherical top end, a threshing concave plate is arranged below the threshing roller and comprises a concave plate body, the concave plate body comprises two side plates, supporting plates are arranged between the two side plates, a longitudinal separation plate is arranged between the two supporting plates, separation bars are arranged on the longitudinal separation plate, and the separation bars and the longitudinal separation plate are flush with the side plates. A separation roller is arranged on one side of the flowing direction of crops, and separation teeth and separation plates are arranged on the separation roller in a staggered mode. A separation concave plate communicated with the threshing concave plate is arranged below the separation plate. Through rubbing between the threshing teeth and the threshing concave plate, threshing is achieved, power consumption is little, and cost is low. Through the threshing concave plate, while passing ability and screening efficiency are guaranteed, strength and use reliability are improved, and the crushing rate is lowered; meanwhile, through replacement of the corn kernel threshing and separating device, the effect of harvesting corn crops at the same time is achieved, and the use rate of a rice and wheat harvester is improved.

A functional element, in particular a cooktop or control panel, having a flat substrate composed of or of glass or glass ceramic, in which a coating that contains a crosslinked polysiloxane is applied to the substrate. In order to improve the scratch resistance of such a coating, according to this invention, a covering layer that contains an uncrosslinked polysiloxane is applied to the coating.

An adhesive bonding film comprises at least one layer of thermally curable resin. The thermally curable resin includes embedded metal particles adapted to be excited to produce heat for curing the resin.

The present invention relates to a powered hammer device including: a hammer with at least a first and a second projection; at least one translation dog adapted to engage with said projections, and a drive mechanism capable of moving the translation dog substantially reciprocally between a first and a second opposed directions, characterised in that the translation dog is adapted to engage with the first projection to move the hammer in the first direction, the translation dog then engaging the second projection to move the hammer in the reciprocal second direction.
