Kit of building blocks for constructing educational electronic circuits comprising a ferromagnetic base plate (10) with the diagram (21) of the circuit to construct. A transparent plastic sheet (30) covers the diagram. A group of magnets (40, 41) rest on the plastic sheet attracted by the plate (10). The surface of the magnets (40, 41) is electrically conducting. A plurality of building blocks can be detachably mounted on the magnets (40, 41), each magnet (41) connecting the steel sheets (702) of the building blocks that rest on it. The steel sheets of the blocks are designed so that the attraction forces that arise between the magnets and the sheets drive the modules exactly to a desired equilibrium position.

A transfer unit used with an image forming apparatus includes an upper housing having a transfer belt of an endless track structure to transfer an image from a photoconductive unit of a main body of the image forming apparatus, and a plurality of rollers to support the transfer belt to rotate therein, and a lower housing removably connected to the upper housing, and having a cleaning unit to clean the transfer belt. The transfer unit is removably mounted to the main body of the image forming apparatus. Accordingly, the transfer unit is facile to be connected to and separated in a vertical direction from the main body of the image forming apparatus. Further, it is convenient to replace the transfer unit since the relative position thereof can be controlled with respect to a contacting object, such as the photoconductive unit.

The invention concerns a storage apparatus for rod-shaped articles, including a housing with a closable opening for filling and emptying the storage apparatus, wherein within the housing is arranged a flexible belt element which is designed for variable adjustment of a storage space depending on the fill level, which is distinguished in that the storage apparatus is designed for filling with a multi-layer, disorderly mass flow. Furthermore, the invention concerns an apparatus and a method for filling a corresponding storage apparatus.

A conveyance seat includes: a seat frame; a seat pad that covers the seat frame; and a seat cover that covers the seat pad and that is fixed to the seat frame. The seat pad has a U-shaped portion formed by a supporting portion, a side surface portion that is continuous with the supporting portion, and a tension adjusting portion that is continuous with the side surface portion, the tension adjusting portion having a protruding portion as a portion of the tension adjusting portion that protrudes toward the seat cover. The protruding portion abuts against the seat cover.

An elevator comprisinga hoistway;an elevator car vertically movable in the hoistway;a counterweight vertically movable in the hoistway;at least one tightening wheel located in the lower end of the hoistway;at least one rope wheel located in or at least in proximity of the upper end of the hoistway;a first roping interconnecting the car and counterweight and passing around the at least one rope wheel located in or at least in proximity of the upper end of the hoistway;a second roping interconnecting the car and counterweight and passing around the at least one tightening wheel, the tightening wheel being mounted movably back and forth in a first direction towards the second roping, and in a second direction away from the second roping; andmeans for exerting force on the tightening wheel to move it in the first direction so as to tighten the second roping.The elevator further comprises means for limiting the movement speed of the tightening wheel towards the first direction and the second direction.

The invention belongs to coal mine winch dispatching equipment, in particular to a dispatching winch system. It solves the problems of difficult maintenance of counterweight dispatching winch equipment, high risk factor of personnel belonging to high-altitude operations, long operation time and insufficient tension of steel wire rope. A dispatching winch system includes dispatching winch and iron ox. The dispatching winch passes through the wire rope II and For the iron ox, the steel wire rope II is wound on the drum of the dispatching winch, and the two ends of the steel wire rope II respectively go around a number of guide wheels to connect with the forward and backward ends of the iron ox, and also include the civil foundation and the hydraulic control system fixed on the civil foundation. There are two sets of hydraulic control systems, and the two sets of hydraulic control systems are respectively connected to the wire rope II located on both sides of the dispatching winch. The invention has high degree of automation, complete intelligent protection, simple operation, safe and stable operation, and low requirements on the working environment.

The invention discloses an all-terrain shock-absorbing suspension compound crawler robot mobile platform, which comprises a disk frame and crawler belt traveling mechanisms fixed on both sides of the disk frame. The load-bearing wheels on the robot mobile platform are floatingly installed on the disk frame through the Christie suspension frame, which can well reduce the impact of the uneven road surface on the robot body, and has good cushioning and shock absorption performance. The sprockets at both ends of the track not only play the role of driving and positioning, but also the sprockets at both ends are suspended on the frame through two first suspension arms arranged in a figure-eight shape, and the upper end of the first suspension arm and the frame can rotate Connected, the lower end is elastically suspended on the upper frame through the first elastic body, and after assembly, the first elastic body is in a stretched state, and this structure also makes the two sprockets play the role of tightening the track. The wheelbase between the two sprockets can automatically adjust the front and rear wheelbases according to the terrain and the platform load. Through real-time adjustment, the track has tension and does not come off, ensuring that the robot can work effectively and stably.

The invention discloses a cleansing stick and a preparation method thereof. The cleansing bar comprises the following components in parts by weight: 5-15 parts of glycerin; 10-20 parts of 1,3-butylene glycol; 33-60 parts of surfactant; 1-8 parts of sodium stearate; 2 parts of stearic acid ‑5 parts; Candelilla Wax 2‑5 parts; C12‑15 Alkyl Benzoate 5‑10 parts; Skin Conditioner 0.9‑2 parts; Adsorbent 2.2‑6.4 parts; Silica 0.9‑1.5 parts; Surfactants include at least two of sodium cocoyl isethionate, sodium C14‑16 olefin sulfonate, sodium methyl cocoyl taurate, coco‑betaine; skin conditioning agents include panthenol , allantoin, bisabolol, and vitamin E acetate; the adsorbent includes at least one of diatomaceous earth and volcanic ash.
