Platen Moved By Elastically Deformable Pressure Member Patents (Class 100/269.02)
  • Patent number: 8936695
    Abstract: A composite layup is formed on a tool and placed on a contoured part. The tool is contoured to substantially match the contour of the part. A set of location data is generated which represents the location of the part in space relative to the tool. An automated manipulator uses the location data to move the tool into proximity to the part and place the contoured layup on the part.

  • Patent number: 8468866
    Abstract: In the die cushion device, a shock absorber device relieves shock between a cushion pad and a support section. The shock absorber device includes a damping section and an elastic section. The damping section generates reaction force in accordance with the relative speed of the cushion pad with respect to the support section. The elastic section generates reaction force in accordance with the relative displacement of the cushion pad with respect to the support section. The controller section controls a servomotor so that a speed difference between the speed of the slide member and the speed of the support section is set to be a predetermined target speed difference value that changes over time.

  • Patent number: 7690298
    Abstract: A unit for compacting waste prior to disposal provides a waste compaction unit for fitting into a housing comprising a lid and an interior for collecting waste. The compaction unit comprises a plunger comprising bellows housed in the lid; a pneumatic locking mechanism housed in the lid; and a pump connected to the plunger via the locking mechanism wherein the pump is arranged in operation to activate the locking mechanism prior to inflating the bellows to extend the plunger axially towards the interior of the housing such that any waste collected therein is compacted.

  • Patent number: 7322286
    Abstract: The invention relates to a bin for storing a volume of waste that can be reduced by compaction. The bin includes an apparatus for reducing the pressure exerted in the volume of the bin, under the effect of a vacuum, and ensures that the waste is compacted. The bin includes a tight deformable enclosure in which the waste is collected, optionally contained in a disposable bag, and the tight deformable enclosure includes at least one lateral wall consisting of an assembly of rigid plates or segments (2) which are articulated in relation to each other in such a way as to form a deformable apron that subjects the waste to a compression force between the lateral deformable apron wall and the opposite wall, under the effect of the vacuum being exerted in the enclosure, one of the sides of said enclosure being open for introducing waste, and provided with a tight cover (6).

  • Patent number: 7114436
    Abstract: A safety interlock and retraction mechanism for all types of presses comprising a sensing or activating valve which does not apply full force to a press ram until the ram displaces to the expected work material thickness and a pneumatically operated retraction mechanism which eliminates the need for a return spring. The art differentiates between the thickness of an operator's finger relative to a work material thickness in order to promote safety. The art further provides an increased press ram force by eliminating the return spring force subtracting from the ram force.

  • Patent number: 6539852
    Abstract: A device for attaching a compensation weight (13) with an adhesive layer (17) to an attachment surface (18) of a vehicle wheel (19) for purposes of unbalance compensation. The device has holding structure with two holding parts to secure a compensation weight and with a pressing element (4) pressed onto a rear surface (16) of the compensation weight (13). A guide with which the holding structure may be guided to an unbalance compensation site of the attachment surface (18) and pressed thereto. The pressing element (4) has a pressing surface (8) deformable as a function of the pressing force so that rear surface (16) of the compensation weight lies on the pressing surface (8). The pressing surface (8) in the unstressed basic position of the pressing element (4) has a shape which transfers the pressing force to the middle section of the compensation weight (13).

  • Patent number: 6530315
    Abstract: In a diaphragm (3) of a diaphragm press for separating liquid and solid materials by action of a pressure medium on the materials (7) via the diaphragm (3), the functions of sealing and retention are separated. This is accomplished by a dual embodiment of the diaphragm (3) in the form of a substantially sealing diaphragm seal (14) and a substantially retaining diaphragm carrier (13). A force transmission from drainage elements (6) in the press chamber (4) of a pressing vessel (1) of the diaphragm press to the diaphragm (3) can be accomplished by the diaphragm carrier (13) in a manner that treats the material gently. This substantially improves the service life of the diaphragm (3).

  • Patent number: 6508099
    Abstract: A hemming machine is disclosed having a base, a nest adapted to support a part to be hemmed, a nest carrier which supports the nest and in which both the nest and nest carrier are vertically movably mounted to the base. At least one hemming die is laterally slidably mounted to the base and movable between an extended position in which the die overlies a portion of the nest, and a retracted position in which the die is spaced laterally outwardly from the nest. A lock unit selectively locks the nest carrier against vertical movement relative to the base in at least one, and preferably two positions, so that, with the nest carrier locked against movement relative to the base, inflation of a hydraulic bladder sandwiched between the nest and nest carrier displaces the nest vertically upwardly from the carrier so that the part carried by the nest is compressed against the hemming dies and performs the hemming operation.

  • Patent number: 6237483
    Abstract: An apparatus for performing a global planarization of a surface of a deformable layer of a wafer on a production scale. The apparatus includes a chamber having a pressing surface and containing a rigid plate and a flexible pressing member or “puck” disposed between the rigid plate and the pressing surface. A wafer having a deformable outermost layer is placed on the flexible pressing member so the deformable layer of the wafer is directly opposite and substantially parallel to the pressing surface. Force is applied to the rigid plate which propagates through the flexible pressing member to press the deformable layer of the wafer against the pressing surface. Preferably, a bellows arrangement is used to ensure a uniformly applied force to the rigid plate. The flexible puck serves to provide a self adjusting mode of uniformly distributing the applied force to the wafer, ensuring the formation of a high quality planar surface.
