Embodiments can provide a test tube vacuum retainer system, comprising an outer body comprising a midline plate; one or more side walls, a bottom wall, and a top plate comprising an access hole; a test tube holder comprising a sealant ring; a base; and a vacuum tube comprising an external outlet; wherein the test tube holder is secured within the outer body to the base, which in turn is secured to the midline plate; wherein the vacuum tube is connected to the test tube holder at a first end, and the external outlet is configured to be connected to a vacuum pump configured to apply a vacuum force to the test tube holder when a test tube is inserted into the access hole and placed onto the test tube holder.

A gripping device (10) for sheet-shaped elements (L) comprising: at least one longitudinal bar (20) adjustable in length and provided with a plurality of suction gripping members (30) connected along a longitudinal axis (A) of the longitudinal bar (20).

A double ended hand tool created to pick up place and position flatback crystals, gems or other tiny items is disclosed. The tool contains a hollow, conical end which securely encases each crystal allowing the operator to easily position the crystal with no slip. The tool has a first end and a second end coupled by a shaft. The first end has a wax tip which allows the user to pick up crystals or other small items. The second end has a hollow narrow extended portion which allows the users to manipulate the crystal or other small items.

A vacuum device for a material handling system includes a vacuum device body and a sealing element. The vacuum device body has a vacuum passageway in which a vacuum is generated in response to activation of a pressurized air supply that forces pressurized air through a venturi device. The sealing element moves to a sealing position to substantially seal the vacuum passageway when the air supply is activated, and is urged toward the sealing position via pressurized air that is diverted from an inlet of the vacuum device to the sealing element. The sealing element moves to substantially vent the vacuum passageway when the air supply is deactivated. The vacuum passageway may be in fluid communication with a vacuum cup, which seals against the object when the sealing element is at the sealing position and the vacuum generating device generates at least a partial vacuum in the vacuum passageway.

The invention discloses a device (1) for releasing glasses (2) from the bodies (3) of vehicles where the device (1) comprises a frame (4), at least one suction pad (5), one guide pulley (6) fitted with two guide grooves (7) for guiding a cutting wire (8), or two guide pulleys (6) with a common central line, and two winding pulleys (9). The winding pulleys are fitted with winding grooves (10) for winding the cutting wire (8) and a spacing element or a spacing pulley (11) keeping the cutting wire (8) at a safe distance from the suction pad (5). During releasing the glass (2) the cutting angle () of the cutting wire (8) does not exceed the value of 90. Each end of the cutting wire (8) is wound onto the winding pulleys (9) due to the guide grooves (7) wherein a safe distance from the suction pad (5) is ensured to eliminate their damage.

The pressure balancing device comprises a housing, a deformation medium accommodated in the housing and capable of deforming under compression, and a sealing member movably connected with the housing and capable of deforming under pressure. When part of the deformation medium is compressed by the sealing member, the deformation medium deforms so that a part, not compressed, of the deformation medium compresses a corresponding part of the sealing member to make it protrude outwards. The pressure balancing device is simple in structure, easy to assemble and convenient to operate, and raw material cost and processing cost are saved a lot.

A suction device that holds a member by suction in a stable manner is provided. The suction device includes a columnar main body, a flat end face formed on the main body, a concave part formed in the end face, a fluid flow-forming means for forming a fluid swirl flow in the concave part by discharging fluid into the concave part, the fluid swirl flow generating negative pressure that applies suction to a member, and a linear guide groove formed on the end surface along a direction in which the fluid discharged into the concave part flows out of the concave part.
