The present invention is a retractable screen (22) and frame (24) assembly (20). The frame (24) includes a first track (32) and a second track (34) in spaced and parallel relationship to the first track (32). The retractable screen (22) includes a canister (36), a screen cloth (38), a control bar (40), a first glide (42), a second glide (44), and a biasing device (46). The biasing device (46) is disposed between a first end (52) of the control bar (40) and the first glide (42). The first glide (42) is inserted into the first track (32) and the second glide (44) is inserted into the second track (34). The glides (42, 44) slide along the respective tracks (32, 34) while the biasing device (46) biases the first end (52) of the control bar (40) with respect to the first track (32). The biasing provided by the biasing device (46) prevents the control bar (40) from binding with the tracks (32, 34) as the control bar (40) and the glides (42, 44) are slid along the tracks (32, 34).

A draft protection device for a laboratory instrument. The device encloses a weighing compartment that surrounds a balance pan. The draft protection device includes a rear wall, a front wall, two sidewalls, a top cover, and a floor that is delimited by border edges. The draft protection device further includes at least one guiding means that is connected to the top cover and serves to guide the movement of at least one horizontally slidable sidewall, and / or a holder means that is connected to the top cover and serves to hold the front wall in place, wherein the guiding means and / or the holder means supports the weight of the at last one sidewall and / or the front wall in such a way that the wall(s) is pushed by a biasing torque against the floor of the weighing compartment. This torque is supported by the border edge facing towards the respective wall.

A metering device for utilization with a syringe, which features on a syringe cylinder a fastening portion with at least one axially directed sensing surface projecting from the upside, and at least one alignment nose projecting from the outer perimeter of the fastening portion, and a plunger with a plunger rod, the metering device having an accommodation for the fastening portion of the syringe cylinder, the accommodation having an axial opening for axially inserting the fastening portion into a fastening position, a sensing device disposed in the accommodation with at least one sensing means projecting from a basis surface of the sensing device facing the axial opening, for sensing the at least one sensing surface of a fastening portion inserted in a fastening position.

The invention discloses a double-color mold capable of preventing products from falling off. The double-color mold comprises two rear mold bodies which are the same in structure; each rear mold body comprises a lower mold plate and a lower mold core; the formed first-color products are left in the lower mold cores; two sliding blocks are arranged on each lower mold plate, and the sliding blocks are slidably connected to the tops of the lower mold plates through guide sliding straight grooves; mounting holes are formed in the groove bottoms of the guide sliding straight grooves, and the mounting holes are located in the sides, away from the lower mold cores, of the sliding blocks; vertical oil cylinders with upward output shafts are mounted in the mounting holes, and lifting blocks are connected to the output shafts of the oil cylinders; first bevel faces are arranged at the upper ends of the lifting blocks and incline in the direction of the lower mold cores from top to bottom, and thesides, away from the lower mold cores, of the sliding blocks are provided with second bevel faces corresponding to the first bevel faces; and reset springs and pressing blocks are connected to the sides, close to the lower mold cores, of the sliding blocks, the reset springs are fixed into the guide sliding straight grooves, and the pressing blocks are located above the guide sliding straight grooves. According to the double-color mold capable of preventing the products from falling off, the problem that the first-color products are prone to falling off when rotating along with the rear moldbodies is solved effectively.

A piston-type internal combustion engine is formed of a high performance synthetic resin material. The cylinders and pistons have an octagonal profile. Two or three rows of pin roller bearings are positioned in transverse semi-cylindrical grooves formed on the cylinder walls, to afford smooth, low-friction rolling contact and to seal the compression from leaking around the piston. There are angle support pieces fitted within the annular channels at respective vertices or corners, and are adapted for rotationally supporting the ends of adjacent pin roller bearings.
