摘要:
A mold for manufacturing interlocking, dry-cast concrete retaining wall blocks in an upright orientation comprises a mold box comprising two side walls joined to end walls to define a mold cavity, a top face, and a substantially open bottom face. Partitions configured to define a space between adjacent blocks or a space between a block and a side of the mold box extend parallel to the side walls of the mold box substantially from the top face into the mold cavity, to form first transverse portions of the profile of the top and bottom surfaces the blocks which do not include any undercut portion that would impede removal of the mold box in a substantially vertical direction. At least one removable insert comprises insert members which, when positioned in the mold box beneath the partitions, form remaining transverse portions of the profile of the top and bottom surfaces, the remaining transverse portions including at least one undercut portion. The insert members, when in position in the mold box for casting, are substantially in lateral alignment with respective bottom surfaces of at least some of the partitions and can be inserted and retracted through openings in an end wall of the mold box.

The present invention relates to a substrate for a thin film photovoltaic module, characterized in that it is a cementitious product with average surface roughness Ra not higher than 500 nm. The invention also relates to the cementitious product as such, the thin film photovoltaic module comprising it, and a method of molding both of them.

A block-forming toy includes a plunger, a mold and an ejector plate. The plunger includes a shaft that passes through a barrel. The two pieces are able to move with respect to one another. Each piece connects to either the mold or the ejector plate, using male and female locking mechanisms. Subsequent to assembling the toy, the mold may be filled and packed with a moldable material. By pulling the plunger up to move the mold upwards relative to the ejector plate, and thus relative to the casted article, the block-forming toy may be used to easily remove the formed block of moldable material from the mold. A variety of mold shapes may be used to create additional blocks to form structures of moldable material. Examples of moldable material include sand and snow.
摘要:
A sleeve for optical communication and method for manufacture for the sleeve for optical communication, for which withdrawal force for ferrules, which are generally used in the technical field of optical communication, or connection loss between ferrules is a predetermined value, and for which manufacturing steps are reduced so as to allow reduction of manufacturing cost. The invention is made by press-molding ceramic feedstock, which after cold isostatic pressing and sintering are performed thereto, and is made so that an inner circumferential surface, of a through-hole for inserting a ferrule formed on the length-direction of the axis, has a sintered state.

A method for making reconstituted limestone blocks includes using a batching plant to make a mixture comprising crushed limestone and cement. The mixture may additionally include water and an additive, such as a plasticizer. The batching plant has been modified to be compatible with the mixture. Next, the mixture is transferred from the batching plant to a mobile stamping machine having a mold box, a hopper, and a feed apparatus configured for transferring the mixture from the hopper to the mold box. Finally, the mobile stamping machine is activated so that the mobile stamping machine forms a construction block by transferring the mixture from the hopper to the mold box, depositing the construction block out of the mold box, and then moving to a next location. The mobile stamping machine is configured to produce approximately 100 construction blocks per hour.

Multi-plate powder press (100) for producing a dimensionally accurate pressed part from a compressible material which is fillable into a die (2), having a punching device (3) comprising a multitude of punches (6) and components adjustable relative to one another in the axial direction and adjustable relative to a press part, a drive unit for adjusting the punching device (3) and/or the punches (6) and components, adjustable relative to one another, in and/or counter to a pressing direction, and a numerical control device which is set up and is programmable in order to control a movement sequence of the punching device and/or the punches and components, adjustable relative to one another, in accordance with a control program. The multi-plate powder press (100) has a control command input element for inputting control parameters and has a display element in order to graphically display the punching device (3) and/or the punches (6) and components, adjustable relative to one another, and also movement sequences. Furthermore, a method for controlling the multi-plate powder press (100) is provided.
