Sofa frame and assembled sofa, comprising back boards, side boards connected to back boards, and face board connected to side boards; said side boards are relatively configured on the two sides of the back board; the two sides of the face board are respectively connected to the side boards on both sides; said face board comprises at least two folding blocks and hinges connected to the folding blocks. In the above-mentioned sofa frame, as hinges are used to connect adjacent folding blocks, the face board becomes a folding structure. Thus, during transportation, the folded face board occupies less space to reduce transportation cost.

Sofa frame and assembled sofa

A sofa frame, a vertical support bar and an assembled sofa. The sofa frame includes two side boards, a face board connected between the front ends of the two side boards and a back board connected between the rear ends of the two side boards. The two side boards, the face board and the back board forms a detachable frame structure. Between the face board and the back board, a vertical support bar is connected. The rear side of the vertical support bar is fixed with a connecting piece. By fixing and connecting the connecting piece and the back board, the support of the back board is strengthened. The lower end of the vertical support bar is connected with a support leg to contact the ground. The sofa frame is a detachable structure, which can be disassembled for packaging and transportation, and assembled again later.

The present invention provides an arch structure for multi-band base station antenna, the arch structure comprises two interface units for connecting with the side edge of a reflector, and a plurality of snap-fits for fixing with the bottom of the reflector, wherein at least two snap-fits in the plurality of snap-fits are not arranged on a projection mid-axis of the arch structure. According to the arch structure of the present invention, it can effectively avoid the interference between the arch structure and the dipole or dipole isolation wall, and enhance the stability of arch structure, so that the width of the arch structure can be reduced and the manufacturing cost can be saved.

A spiral wound membrane element and a method for cleaning a spiral wound membrane sheet are provided. The spiral wound membrane element comprising a perforated central tube; one or more membrane sleeves, each sleeve comprising two membrane sheets enclosed at two edges around a feed spacer sheet and wrapped around the central tube; a permeate carrier sheet attached to the central tube at a first edge opposite a second edge; and a seal on third and fourth edges of the permeate carrier sheet. The method comprises introducing two solution with different solute concentration to two sides of the spiral wound membrane sheet; establishing a concentration gradient between the first and second sides; communicating a first solvent from the first side to the second side to remove a foulant located on the second side of the membrane sheet; and collecting a waste stream that contains the foulant.

Disclosed is a spiral wound membrane element that provides two permeate streams through a permeate carrier sheet. The spiral wound membrane element is sealed such that the only communication with the permeate carrier is through a membrane sleeve. The first permeate stream flows spirally inward and the second permeate stream flows in the opposite direction, spirally outward. The permeate carrier sheet is sealed at two edges so that the permeate streams can only discharge from opposite, unsealed edges of the permeate carrier sheet. The first permeate stream may be collected in a central collection tube and the second permeate stream may be collected in a peripheral region of the membrane element.

A Chinese-character input method and system is provided to allow users to input Chinese characters to a data processor with a reduced keyboard, such as a mobile-phone handset with a CCITT-compliant (Consultative Committee in International Telegraphy and Telephony) keyboard having only 12 keys. This Chinese-character input method and system allows the user to input Chinese characters to the data processor through a plurality of virtual keyboards which collectively display a set of phonetic symbols, such as those in the Mandarin Phonetic Symbol Set or the Roman Symbol Set, so that the user can perform the input operation through a pronunciation-based input scheme. The Chinese-character input method and system arranges the virtual keyboards in relational layers in accordance with the Mandarin Phonetic-Symbol Combination Rules or the Chinese Roman-Symbol Combination Rules, so that the user can perform the task of Chinese-character input to the data processor more conveniently and efficiently than the prior art.
