Self-Lubricating Connector
A self-lubricating connector with a housing having a contact receiving cavity with a contact provided therein. A lubricating device is positioned in the housing proximate the contact. The lubricating device extends into the contact receiving cavity and has lubricant provided therein. The lubricant from the lubricating device is deposited or on the outside surface of the contact as the contact is moved between the first position and the second position, reducing wear on the contacts as the contacts are moved between the first position and the second position.

DEVICES AND METHODS CONFIGURED TO MANIPULATE FRICTION BETWEEN A WORKING PIECE AND A DEEP DRAWING TOOL IN A DEEP DRAWING PROCESS
The invention relates to a system for making a metal product, comprising —a lubrication source (225) for applying a first lubricant (235) on a punch side of a sheet metal blank (205); —a controllable current source (250) for applying different amounts of current; and —a punch (215) and a die (220) for drawing the sheet metal blank (205) into a metal product, wherein the controllable current source (250) is electrically coupled to one or more of the punch (215), the die (220), or a contact point for applying current through the first lubricant (235) while the sheet metal blank (205) is drawn by the punch (215) and the die (220) into the metal product and while the metal product is being ejected from the punch (215). The application further relates to a method for making a metal product with a such system. The invention relates also to a container manufacturing system (700), comprising —a cylindrical ram (720) comprising a ram body (722) and a ram nose on a distal end of the ram body (722), the ram nose engageable with abase of a container preform; —a die (730) comprising an opening concentrically aligned with the cylindrical ram (720), the opening sized and shaped for receiving the container preform in response to the ram nose engaging with the base of the container preform and the cylindrical ram (720) driving the container preform through the die opening; and —an ultrasonic device (740) coupled with the die (730), wherein the ultrasonic device causes the die (730) to vibrate while the cylindrical ram (720) drives the container preform through the die opening. The application further relates to a method for forming an aluminium container with such system and a die (730) for forming an aluminium container.
IMPROVEMENTS IN METHODS AND SYSTEMS REQUIRING LUBRICATION
Methods and systems in which a shapable mass, which is processed according to the method or in the system, has a lubricant applied thereto. As it is processed in the system, the shapable mass having the lubricant applied thereto is used to transfer lubricant to a part or parts of the system.
DELIVERY DEVICE, MOLD USING SAME, AND DELIVERY METHOD
A delivery device includes a first fluid supply path to supply first fluid, a second fluid supply path to supply second fluid to be mixed with the first fluid for obtaining a mixture, a mixing chamber to which first and second fluid supply paths are connected and in which the first and second fluids are mixed, and a delivery port for delivering the mixture from the mixing chamber, in which the first fluid supply path is connected to a downstream side end part in the flow direction of the mixing chamber, the second fluid supply path is connected to the upstream side end part in the flow direction of the mixing chamber, and the delivery port is provided on a side wall of the mixing chamber between the downstream side end part and the upstream side end part.
System for cleaning, protecting and lubricating hyperbolic rollers and bearings placed in a rotating rotor which is used for straightening wire, rod or reinforcing bar, using air and oil
A system and method for cleaning, protecting and lubricating hyperbolic rollers and bearings for bending, using air and oil, placed in a rotating rotor (1) that contains rollers (32) placed on bearings (34) and shafts (33) inside roller housings (30), where rollers (32) are positioned at an angle with respect to the bending axis and, as bending occurs they cause bending and also as rotor (1) rotates around the item being bent it straightens and feeds the item. Rollers (32) are placed on bearings (34) and are protected through rotational seals (35). The bearings' (34) area of rollers (32) inside the rotational seal (35) is supplied with air at pressure higher than the atmospheric, so that inflow of contaminants are inhibited, or is supplied with air enriched with oil so that bearings (34) are lubricated, and rotational seals (35) located next to bearings (34) of the rollers (32) allow the air flow from the area between the bearings towards the surrounding area.
