A microfabricated capillary electrophoresis chip which includes an integral thin film electrochemical detector for detecting molecules separated in the capillary.

A system for moving a camera in space has a track with two spaced-parallel rails, each rail having two upward-extending spaced-parallel lips, and a dolly holding the camera and riding upon both rails of the track. The track is preferably segmented with each elongate rail segment preferably in the cross-section of half of a tube, while the dolly has wheels that contact only, and that ride upon, the upward-extending spaced-parallel lips of each half-tubular rail. The camera is mounted close upon the support platform of the generally rectangular wheeled dolly, which is itself squat and low to the track's two spaced-parallel rails. According to the geometries of construction, the camera is relatively insensitive in space and in angular orientation to such irregularities in track and moving dolly as are in any case minor by design, and the camera can be moved along complex paths with great precision for purposes of motion pictures and movies.

An intermediate electrical connector device, which easily enables “floating”, includes an intermediate board (20) having two connecting sections (23A) and (24A), which are respectively formed at the edges (23) and (24), to connect between two connecting bodies (40) and (40′), and a holding body to hold the intermediate board between two connecting sections. The holding body is divided into a plurality of sub-members (10) and (10′) at a surface perpendicular to the fitting direction between the two connecting bodies. The intermediate board is held by one of the sub-members through at least partial fitting, and forms space from another sub-member. The sub-members can be displaced relative to each other on the surface perpendicular to the fitting direction at least one direction parallel and perpendicular to the intermediate board.

An all-in-one combination layout tool is provided for marking center lines for spacing studs, marking rip lines, marking cut lines for roof rafters and staircase stringers, and other purposes. The tool comprises a rectangular base plate, an elongate locator bar with a rounded pivot corner, and two connectors to connect the locator bar to the base plate in a variety of configurations. The base plate includes multiple “pivot” points for pivotally connecting the locator bar, two strategically-placed arcuate slots for marking or making angle cuts, and two strategically placed parallel slots for configuring the tool to mark or make rip cuts. Angle markings are provided on two adjacent edges of the base plate, and 1 / 16-inch markings are provided on the opposite adjacent edges. The base plate is planar and has no enlarged flange or lip that would hinder its use in laying out staircase stringers.

The invention relates to a blocking and positioning device for a buffer type conveyor. The device is formed in the manner that two sets of blocking and positioning mechanisms are correspondingly connected with a synchronous rotation interlocking transmission mechanism. The blocking and positioning mechanisms comprise rotation supports, rotation shaft sleeves, rotation shafts, blocking wheels, positioning plug pins, compression springs, positioning sleeves, blocking pieces and reversing drive rods. The synchronous rotation interlocking transmission mechanism ensures that the blocking and positioning mechanisms are switched during synchronous reversing and structurally comprises an installation plate, an air cylinder, an air cylinder rear lug ring support and a synchronous rotation connecting rod. According to the blocking and positioning device, a single work unit can be positioned, and conveying of multiple subsequent units is blocked; and the blocking and positioning device is simple and compact in structure, small in size and stable and accurate in positioning and has the buffer function. According to the blocking and positioning device, the air cylinder is connected with the synchronous rotation connecting rod to drive the blocking and positioning mechanisms to rotate, and positioning mechanisms and blocking mechanisms can be switched; it is ensured that one conveying unit is accurately and stably conveyed into a station, and meanwhile the subsequent units are prevented from following the corresponding conveying unit to pass the work station; and accuracy and safety of equipment operation are effectively improved.

A shift-drum speed change mechanism includes a first drum spring biasing a first drum toward a first side in an axial direction, which is a side on which a first slider comes into contact with a first speed change member, a first fork spring biasing a first shift fork toward a second side in the axial direction, which is a side opposite to the first side in the axial direction, with a weaker biasing force than the first drum spring, and a first stopper member for the first drum, defining an end of movement of the first drum toward the first side in the axial direction.

The present invention relates to the technical field of LED street lamp, in particular to structure of a reflector panel of the LED lamp. A reflector panel comprises a base, the base has multiple reflector cups, which are divided into two groups according to the direction of their openings, all reflector cups in each group have the same direction of their openings, the directions of the openings of the reflector cups in two different groups are opposite. The reflector panel of the present invention can form the illumination band with even illuminance on the street and cause small light loss.

A braking device for an electric motor includes two brake pads, which are connected to brake disks, which cooperate with a brake rail. The two brake pads are rigidly connected by a connecting element, which is able to experience a certain deflection under the influence of a piezoelectric element, which is used to distance the two brake pads from each other. An assembly, which includes the two brake pads and their connecting element, is fastened on a support by a fastening device, which is elastically deformable along the direction at right angles with respect to the brake rail and to the two brake pads. The elastically deformable fastening device is formed of plates, which are connected on one end to the assembly and on the other end to the support.

The invention relates to a process for the production of cellular or foamed, cast concrete bodies that are reinforced with metallic reinforcements, and to a reinforcement support frame for use in the production of cellular or foamed, cast concrete bodies that are reinforced with metallic reinforcing bars.
