Abstract:
A molding plant for conveying molds, preferably molds for chocolates or similar products. A drive shaft, which includes conveying screws mounted on a shaft, conveys the molds along a processing path through stations in the plant. The underside of each mold has downwardly projecting studs or projections that engage between threads of the conveying screws. The studs are arranged such that the molds can be conveyed along at least two different, transverse processing paths. Preferably, the studs are positioned such that the engagement between the studs and the screws is along a midline of the molds.
Abstract:
Continuously-operating chilling cabinet for treating a mass contained in molds, for example a chocolate mass or the like, such that after the entrance of the chilling cabinet is a device for lifting the molds as they are fed in and stacked and, in an adjacent position, before the exit from the chilling cabinet is a device for lowering the stacked molds. Above the lifting and the lowering device is a mechanism for holding and releasing the lowest mold of the corresponding stack. Above the stacks, the chilling cabinet houses a horizontal carrier that conveys the molds contained in the top row of the ascending column towards the top of the column made up of descending molds.
Abstract:
An apparatus for making a quartz glass crucible comprises a housing having a first chamber and a second chamber therein, a rotation crucible having an inner surface corresponding in configuration to the quartz glass crucible, means for rotating the rotation crucible, means for shifting the rotation crucible and the rotating means together between the first and second chambers, means placed in the first chamber for feeding a grain material into the rotation crucible, means placed in the first chamber for shaping the grain material in the rotation crucible so as to form a shaped body in the shape of the quartz glass crucible when the rotation crucible rotates, and means placed in the second chamber for heating and fusing the shaped body within the rotation crucible so as to make the quartz glass crucible.
Abstract:
A method and apparatus for reclaiming scrap produced in the manufacture of fabric reinforced thermoplastic resin sheet material so that the scrap may be worked, banded and calendered or extruded to form a finished product. The reclaiming or reworking of the material is made possible by first means for tearing the fabric fibers embedded in the thermoplastic resin into discrete finite lengths, means for mixing the resulting fibers and resin and means for forming the mixture into a new sheet of thermoplastic resin material suitable for many commercial uses. The tearing of the textile fibers embedded in the scrap into minute lengths is accomplished by means for applying shearing force to the opposite surfaces of the segments of scrap, in directions parallel to the surfaces.
Abstract:
Equipment for producing a high voltage rectifying unit wherein there is a resin ingredient tank and a curing agent tank for storing separately the resin ingredient and the curing agent, a closed mixer for mixing the resin ingredient and the curing agent, a vacuum chamber for injecting a mixed thermo-setting resin composition into the high voltage rectifying unit, a chamber for defoaming the injected resin composition, a furnace for curing the injected resin composition by heating, and a carrier apparatus covered to isolate the external atmosphere which may carry the resin composition-injected high voltage rectifying unit from the defoaming chamber to the curing furnace, whereby the procedures from vacuum injection to curing can be carried out continuously and automatically.
Abstract:
Thin-walled articles of thermoplastic material are formed in a continuous apparatus starting with heating and extruding granular thermoplastic raw material in the form of a continuous web which is immediately stabilized by rapid cooling of its opposite surfaces and the stabilized web wherein the material sandwiched between the precooled outer surface layers remains at or near extrusion temperature is fed into a thermal forming station wherein shaping tools form the articles in the web without the need for further heating of the web. Adjustments are provided for correlating the cooling action to different materials and web feed rates, for varying the web feed rates and increments, and for varying the shaping tool movements to adapt for different materials and sizes of articles. After the formed articles are separated from the web the web residue is fed back to be mixed with incoming raw material at the extrusion station.
Abstract:
A particle board manufacturing method capable of manufacturing particle board of a thickness of 1 to 10 millimeters of fine or coarse chips, which includes a filling machine and a press wherein the press comprises a heatable platform for conveying the chip-resin mat from a filling machine to a press in a simple and efficient manner and without causing any distortion of the mat.
Abstract:
This invention relates to an apparatus for manufacturing concrete poles which has a train system running on a rail and stays on a required place to manufacture concrete poles, and is characterized in comprising at least a wire storage device, a caging stand, a mold traverser, a spinning machine and a device for carrying materials or products.
Abstract:
Resinoid wheels are continuously produced by preparing resinoid abrasive compositions each different in the size of abrasive grains contained therein, placing the abrasive compositions into a die in the form of superposed layers, molding the superposed layers into a block, heating the block by a high frequency heater, passing the heated block through multiple pairs of rolls to roll the block into a sheet, blanking out circular pieces from the rolled sheet and baking the circular pieces.
Abstract:
Machine for making crayons or the like comprising means for supplying fluid material to a series of mold cavities in a horizontally rotatable mold table, means for controlling the temperatures of the cavities, means for ejecting the molded products from the cavities, means for receiving the ejected products and conveying them to one or more delivery points and means for removing excess material from the mold table and recycling it, with suitable controls for operating the several elements according to a desired program and with specific improvements in the apparatus and in the method of operation.
