The present invention provides an iron-based metallic glass alloy powder containing an iron-based metallic element group having Fe as the main component thereof, a metalloid element group comprising Si, B, P, and C, a small amount of at least one species of an element group for improving a degree of supercooling, selected from the group comprising Nb and Mo, and, depending on circumstances, a corrosion resistance modifying component, wherein the total amount of the metalloid element group and the total amount of the corrosion resistance modifying component are set to a predetermined range, andthe iron-based metallic glass alloy powder having a particle diameter of 30 [mu]m or less.

The invention relates to electric linear motors and gas springs in reciprocating pumps for oil wells. By the use of this invention a simple, silent, compact and adaptable mechanism can be constructed to drive a wide range of such pumps. The mechanism will sense a variety of pumping conditions and react automatically thereto.

The disclosed invention is a new concept for controlling the flatness of the strip during the rolling of aluminium strip or foil (2). The system consists of a full width bank of cryogenic roll cooling devices (7) acting on the roll (s) (4) and a full width bank of roll heating devices (8) also acting on the roll(s). Both or either of the cooling and heating banks are divided into individually controllable zones. A process automation system controls the action of the cooling and heating banks via feedback from a strip shape meter (9) and / or a predictive process model, in order, by thermal growth / contraction, to create the best roll profile for rolling flat strip.

The invention relates to a LED light matrix (14) equipped with impulse means for illuminating a moving object (10) in a selected area (11) from an oblique direction for video imaging, said LED light matrix (14) including a group of LEDs (15, 16) each equipped with optics for focusing the light produced by the LED, and with the group being located substantially obliquely relative to the object to be illuminated. Separate LEDs (15, 16) of the LED light matrix (14) are so oriented that the intensity distribution of illumination in the selected area (11) is weighted proportionally to the distance.

The present invention generally relates to a diverting system to be used in a combined-cycle power plant. According to the invention, the diverting system is integrated within the by-pass stack and carries out, in a sole component, the functions of by-passing the hot exhaust flow in a single-cycle configuration or guiding it through the HRSG, acting as a diffusor, in an open combined-cycle configuration.

The invention discloses a bus-through clamping-type ultra large-load capacity annular wiring high-reliability PDU (Power Distribution Unit). A waterproof wiring head is arranged at a wire incoming mounting end plate; the wire incoming mounting end plate and a wire mounting insulated end plate are arranged in an overlapping mode at a wire incoming end of a shell; multiple socket modules are arranged inside the shell; a mounting end plate and an insulated end plate are arranged in an overlapping mode at a closing end of the shell; a bus-PE, a bus-L, and a bus-N are respectively arranged inside the multiple socket modules for electrically connecting the above parts. The quick punching clamping-type connection is low in resistance, reliable, durable, stable and small in temperature rise, and fire risks are eliminated; a charged conductor is fixed and an electrical contact point is closed in the insulated shell during the whole process, hidden electrical dangers such as short circuit and contact oxidation are eliminated; due to annular wiring, single-point fault is eliminated, and the power-off range due to multi-point fault is reduced; no broken connection points exist in the whole bus, and connection is firm; temperature rise is over low, and fire risks do not exist; power distribution reliability is high; the appearance size is small, and the space is saved; and the SPD modules have hot-plug functions.

The invention discloses a car chassis fire warning system. It includes a mirror reflective photoelectric module, which is installed on the bottom of the chassis, arranged vertically and vertically to the reflective surface, and is used to emit light to the reflective surface, and send an early warning signal to the early warning module when no reflected light is received; The upper surface of a section of the exhaust pipe with the smallest vertical distance between the chassis is used for reflecting light; the early warning module is used for early warning when an early warning signal is received. The invention can detect and prompt the driver to remove foreign matter when it enters between the chassis and the exhaust pipe, so as to prevent problems before they happen.

A pile driving rig lower cushion made of material having elasticity modulus of 500-3500 Mpa. The lower cushion comprises two end surfaces and at least one side surface. The first end surface is to be placed against the drive cap of the pile driving rig. The second end surface is to be placed against the end of a pile. The lower cushion has at least one flexible section at the side surface that is more flexible than remaining sections of the side surface in at least one direction. The dimensions of the lower cushion are such that the lower cushion fits snugly into the drive cap housing only when the flexible area is compressed. The lower cushion remains in its place within the drive cap housing due to compressive force caused by the at least one flexible section and friction forces resulting therefrom.

An assemblage having a thermally insulating switch and a thermal insulator for constituting an electrical conductor passthrough through the thermal insulator. The thermal insulator insulates an inner space from an outer space, the assemblage having inner connector on the side of the inner space and outer connector on the side of the outer space, which are electrically conductively connectable by the switch. The assemblage has a control unit for controlling the thermally insulating switch, a current flowing through the switch is detectable by the control unit, the switch is controllable by the control unit in such a way that the switch is actuatable only in a substantially zero-current state, and the switch is disposed in the thermal insulator in such a way that thermal insulation between the inner connector and the outer connector is accomplished by way of the switch in the open state.
