Abstract:
An apparatus for producing electrolytically and collecting separately two gases includes an electrolytic tank, a power supply unit, and two gas tanks. The electrolytic tank has a casing with an open top, a plurality of electrode plates which are spaced parallelly in the casing and which are connected electrically to the power supply unit, and a lid member disposed on the open top of the casing. The lid member has first and second cavities in its upper face and a plurality of partition plates and press plates depending alternatively from its lower face. A plurality of clearances are formed between the partition and press plates. Each of the press plates abuts against a top edge of a respective one of the electrode plates. The first and second cavities are formed respectively with a plurality of first and second through holes which are staggered with one another so that the first and second cavities can be communicated alternatively with the clearances. The gas tanks are connected receptively to the first and second cavities. An electrolytic solution is received in the casing so that the electrode plates can be immersed fully in the electrolytic solution.
Abstract:
A clip comprising two half bodies of a symmetrical structure, and two inverted U-shaped clasps combined together, each half bodies having two clasp openings spaced apart in an upper lengthwise edge for the two clasps to fit and catch hold of a vertical sloped wall in each clasp opening, the two half bodies being able to be pressed inward at their heads to open a normally closed lower sides and then to be closed by elasticity of the two clasps when the heads are released.
Abstract:
An electric connecting device composed of a subsidiary board, a main board, a base and multiple electric conducting plates, wherein a U-shaped groove is disposed on two sides of the base, and a locking latch is disposed beside the U-shaped groove, a slantly curved locking projecting portion being formed on the locking latch whereby the subsidiary board can be quickly installed or removed without slipping, an inclined locking pin being inserted into the U-shaped groove whereby the subsidiary board can be installed in a vertical manner or an inclined manner, stop blocks being disposed in an insert groove of the base at large and small intervals so that two kinds of subsidiary boards with different intervals can employ the same electric connecting device.
Abstract:
Disclosed is a rotary lamp for stage lighting control, which utilizes a four-step control switch to control a long lamp and two short lamps which are respectively mounted on a revolving shaft of a seat to rotate at a constant speed.
Abstract:
A process for transferring printed information, in the form of printing ink, from a printed paper to a non-porous substrate by the application of a solvent to the surfaces of an adhesive coating on the printed information surface and a surface of the substrate, followed immediately by the application of pressure to unite the adhesive surfaces together and the subsequent dissolution and removal of the paper leaving the printed information attached to the substrate by means of the adhesive.
Abstract:
A reactor has an inner surface accessible to the hydrocarbon and comprising a sintered product of at least one of cerium oxide, zinc oxide, tin oxide, zirconium oxide, boehmite and silicon dioxide, and a perovskite material of formula AaBbCcDdO3-δ. 0
Abstract:
An electric wheelchair with quick-release drive wheels includes: a chassis, and two guide wheels and two said drive wheels. The drive wheels are rotated by a drive mechanism and connected to the drive mechanism by a quick-release mechanism. To detach the drive wheel, the user can press the cover to make the rolling balls move out of the receiving groove and back to the arc-shaped engaging portion, which allows the hollow shaft to disengage from the drive shaft. Then, keeping pressing the cover can detach the drive wheel from the drive mechanism. To assemble the drive wheel, the user can press the hollow shaft into the axial hole to make the rolling balls engage in the receiving groove, so that the drive wheel is assembled to the drive mechanism. The assembly and disassembly of the drive wheel require no wrenches or other tools, and therefore are very convenient.
Abstract:
A method for cracking hydrocarbon, comprises: providing steam and hydrocarbon; and feeding steam and hydrocarbon into a reactor accessible to hydrocarbon and comprising a perovskite material of formula AaBbCcDdO3-δ, wherein 0
Abstract:
A damping assembly for a front-wheel independent suspension of a four-wheel mobility scooter includes a chassis with two front wheels, and two connecting sleeves. In each of the connecting sleeves is disposed a first shock absorber which includes a rectangular outer pipe and a rectangular inner pipe disposed in and rotated 45 degrees with respect to the outer pipe, between each of the edges of the inner pipe and the inner space of the outer pipe is disposed an elastic rubber The inner pipe has two suspension arms connected to a shaft, respectively, each shaft includes a first connecting arm extending in a width direction of the chassis, the front wheels are connected to the first connecting arms, on each of the shafts is provided a second connecting arm extending upward and hinged with a third connecting arm extending in the width direction of and hinged to the chassis.
Abstract:
An anti-glare light source including a linear light source, at least one sleeve and a light adjusting element is provided. The linear light source is suitable for providing a light. The sleeve covers at least one end of the linear light source. The light adjusting element is disposed between the sleeve and the linear light source, wherein the light adjusting element includes a plurality of prism portions. The prism portions cover a portion of the linear light source and arrange along the extension direction of the linear light source, such that the distribution of the light converges along the extension direction of the linear light source.
