Computer assisted method for the advanced design of bent parts of composite material using a computer assisted CAD system comprising the following stages: a) Supplying the 2D mesh model (11) of the part; b) Generating the 3D outer surface (19) of the part; c) Obtaining the 3D mesh model (51) by adapting the 2D mesh model (11) to the geometry of the 3D outer surface (19) by bending the contour lines (17) of the patterns (13) of the 2D model (11) with respect to some bending lines (23) set up in relation to a bending surface (31) similar to that of the tool provided for bending the part; d) Generating the solid model (53) of the bent part. The invention also relates to a computer program that when it is executed on a computer together with a CAD system it causes the execution of the method.

The invention discloses a structure for detecting a post-grouted inserting type sleeve and steel bar connector through an endoscope method and a method applying the structure and belongs to the technical field of detection. Whether the position of a steel bar in a sleeve is in place or not is observed through an industrial endoscope. According to the method, operation is easy and convenient, the result is visual and reliable, the applicable working condition is wide, and the influence of the site construction condition on themethod is less; and meanwhile, whether a grouting channel and an overflowing channel are unobstructed or not can be inspected, and the guarantee is provided for the quality of subsequent grouting construction.

A blind fastener installation tool which accomplishes the blind installation of a series of fasteners is described in detail in this specification. The blind fastener installation tool comprises a structural housing which features a means for securing a fastener installation assembly in position relative to said structural housing during the blind installation of a fastener; and a means for reciprocating said fastener installation assembly relative to said structural housing at the conclusion of a cyclic blowline-fed or clip-fed blind installation of a fastener. The blind fastener installation tool also comprises a fastener installation assembly comprising (1) a pull rod assembly comprising means for pulling a first portion of a fastener; (2) an annular, piston-actuated, direct action, piston-decoupled pull rod actuation assembly to translate the pull rod assembly relative to said fastener installation assembly when said fastener installation assembly is secured at a fastener installation assembly fastener installation position, thereby pulling said first portion of said fastener until blind installation of said fastener is complete; and (3) a nose assembly comprising (3a) a fastener receptacle for securing the position of a fastener relative to said nose assembly during blind installation of said fastener; and (3b) one or more optional pull rod translation dampening assemblies to smoothly and effectually dampen the sudden translation of said pull rod assembly after pintail break during blind installation of a pintail-break—type fastener. The blind fastener installation tool also comprises an optional fastener delivery assembly, said optional fastener delivery assembly constituting: (1) a clip-fed fastener delivery system; or (2) a blowline-fed fastener delivery system.

A cabinet for the storage of goods requiring refrigeration, includes a modular frame structure, space-delimiting elements and shelves (6) bearing the goods, and equipped with a caloric heat exchanger (8) generating an air flow of a temperature selected to suit the goods, and an air channel system (17) communicating with it. Thus a refrigerated cabinet of any size and design can be transformed from an existing cabinet or a mass-manufactured cabinet product range, without altering the module structure of the non-refrigerated cabinet, incorporating all advantageous characteristics of a modular assembly option. The transformation implies no permanent change in structural design, basic parameters or external dimensions of the original cabinet, so it can be transformed back into a non-refrigerated cabinet at any time, by replacing certain elements and the installation and fitting of further units.

A computer aided wave-shaped circuit line drawing method and system is proposed, which is designed for use with a computer platform for providing a user-operated wave-shaped circuit line drawing function, and which is characterized by the utilization of computer-aided graphic drawing technology to allow a user to define a set of dimensional attributes for a wave-shaped microstrip line, and whereby the shape of the wave-shaped microstrip line will be automatically drawn on a circuit layout diagram. Compared to the prior art, since the invention allows the dimensional attributes and locations of each constituent portions (i.e., segments and turning points) in the wave-shaped microstrip to be precisely drawn on the circuit layout diagram, it allows the realization of a microwave digital circuit board from the circuit layout diagram to have precise characteristic impedance and thus precise electrical performance in actual operation.

Rectilinear drawing machine for drawing material, especially bars, pipes or sections, with at least two movable drawing cars which are driven on a path, one run being assigned to each drawing car, and the runs can be fixed in a variable manner.

The embodiment of the invention relates to the technical field of display and discloses a screen printing plate, a light guide plate, display equipment and a manufacturing method of the light guide plate. By the adoption of the screen printing plate, the light guide plate, the display equipment and the manufacturing method of the light guide plate, tracing of the production information of the light guide plate can be achieved, and accordingly the production control difficulty of the light guide plate is lowered. The screen printing plate comprises a screen printing plate body. The screen printing plate body comprises a screen point printing part corresponding to the light guide plate to be printed. The screen point printing part comprises at least one production information mark printing area, and each production information mark printing area comprises a plurality of printing marks. A covering piece is arranged for each production information mark printing area, and the covering pieces are detachably connected with the screen printing plate body and cover selected printing marks in the production information mark printing areas.
