Patent number: 5284186Abstract: A mat is produced from a single length of rope or other flexible member using a holder assembly which releasably clamps an end of each of a plurality of hollow tubular members. Warp lengths are formed over the clamped tubular members by alternately weaving the lead end of the flexible member over and under adjacent tubes, thereby forming respective groups of aligned loops thereon, until a desired width is obtained. The ends of the tubular members are unclamped from the holder assembly and weft lengths are formed by pushing or drawing the flexible member through the tubular members. A tube is removed from its position within a corresponding group of aligned loops when the pushed lead end emerges therefrom. The ends of the flexible member are wedged alongside a respective weft length to prevent unravelling of the mat.Type: GrantFiled: December 30, 1992Date of Patent: February 8, 1994Assignee: Intermart USA CorporationInventor: Sholem Bontshek

Patent number: 5277406Abstract: A device for limiting the tension in a rope or the like comprises an anchorage plate (8) and a gripping unit (10) containing two piston and cylinder units (34), two gripping members (14) and a hydraulic control circuit which controls the gripping of the rope or the like in a manner dependent on the tension in the rope or the like. Tension P causes the gripping unit (10) and the anchorage plate (8) to separate, thus compressing fluid in chambers (46). This results in the double acting rams (30) biasing the gripping members (14) towards each other under the action of cams (26). If the tension rises above a threshold value the pressurized fluid trips pressure sensitive valve (54) allowing pressurized fluid to reverse reversing valve (55) thus temporarily relaxing the grip on the rope or the like.Type: GrantFiled: April 27, 1992Date of Patent: January 11, 1994Assignee: The Secretary of State for Defence in Her Britannic Majesty's Government of the United Kingdom of Great Britain and Northern IrelandInventor: Derek I.

Patent number: 5277407Abstract: A friction winch assembly for securing automobiles or other heavy objects to a transporting vehicle includes a spindle rotatably mounted on the transporting vehicle, a ratchet gear axially mounted on said spindle, and an actuator cap for threaded engagement on said spindle. A chain or other flexible elongated member is connected at one of its ends to the spindle for winding or unwinding thereon, and at its other end to the automobile. To wind the chain and secure the vehicle, the actuator cap is rotated with a tool for longitudinal movement along the spindle toward the ratchet until longitudinal movement is limited by a collar affixed to the spindle. The actuator cap, ratchet and spindle eventually frictionally engage each other sufficiently so that they rotate synchronously with the spindle while the chain is wound, until the chain tension secures the automobile.Type: GrantFiled: April 15, 1992Date of Patent: January 11, 1994Assignee: Ryder Automotive Operations, Inc.Inventors: Roger Mayne, Earl C.

Patent number: 5275211Abstract: An electromagnetically activated jacquard control arrangement comprising a plurality of control elements each combined with a lifter element (16) and each provided with an electromagnet (19) with an armature (21). There is further provided a lifter plate (7) which, in each working cycle, lifts the lifter element (16) out of a rest position into a working position and which thereafter is again lowered so that the lifter element, in dependence upon the activation condition of the electromagnet, remains in the working position or returns to the rest position. Every lifter element (16) comprises a hook (26) which operates together with a counterhook held in a predetermined elevation. Each armature (21) is rotatably mounted on an axis (24) and by its swinging movement, displaces the counterhook into or out of the path of the lifter element hook. The lifter plate (7) can lift the lifter element beyond the working position into a predetermined zone.Type: GrantFiled: July 21, 1992Date of Patent: January 4, 1994Assignee: Karl Mayer Textilmaschinenfabrik GmbHInventor: Josef Roth

Patent number: 5273223Abstract: A stator coil winding machine for winding a wire around a neck portion of each pole. A spindle through which the wire is inserted is reciprocated in an axial direction thereof. A nozzle is provided at one end of the spindle, and the nozzle is inserted through a slot of a stator core by the axial reciprocation of the spindle. The spindle is reciprocated axially and is reciprocatively rotated at a predetermined angle at opposite ends of the axial reciprocation. Thus, the wire is supplied from the nozzle and is wound around the neck portion. The nozzle is pivotally mounted on the spindle so as to be tiltable in the axial direction of the spindle. In another embodiment, a nozzle swinging device is provided to tilt the nozzle in a direction counter to an advancing direction of the spindle.Type: GrantFiled: March 5, 1992Date of Patent: December 28, 1993Assignee: Odawara Engineering Co., Ltd.Inventor: Takayuki Tsugawa

Patent number: 5273078Abstract: A rod-type three-dimensional weaving method and apparatus sends weft rods from within a rod magazine between groups of warp rods consisting of a large number of warp rods disposed parallel to one another by means of rod pushers substantially continuously by automatically changing a used-up magazine with another one filled with a new set of weft rod groups. To achieve such continuous weaving, a sensor senses a point where one of the rods in the magazine reaches the preset limit for a magazine change, and a control unit acting on the signal from the sensor removes the used-up magazine and brings another magazine filled with a new set of rod groups into the rod filling position. Or the same control unit stops the rod pushers on one side and starts feeding weft rods from the opposite side by employing the magazine and rod pushers on the opposite side of the group of warp rods, with a significant reduction in the weaving time.Type: GrantFiled: June 26, 1992Date of Patent: December 28, 1993Assignee: Three-D Composites Research CorporationInventors: Masahiko Kimbara, Michiya Hayashida

Patent number: 5273079Abstract: A weaving method makes use of a set of weaving frames arranged such that, in each weaving cycle, some of the weaving frames are held in an identical extreme position, while all remaining weaving frames are moved in order to provide different tensions for the top and bottom warp threads at the moment of beating up. The shed is formed so that at the moment of crossing, as the weaving frames change position, the length of the course followed by the crossing warp threads is equal or almost equal to the length of the course followed by the warp threads held in the extreme position.Type: GrantFiled: September 22, 1992Date of Patent: December 28, 1993Assignee: Picanol N.V., naamloze vennootschapInventors: Daniel Beyaert, Ignace Meyns, Henry Shaw

Patent number: 5271435Abstract: A measuring weft feeder for fluid jet looms which measures the weft yarn lengths being inserted into the loom shed is disclosed. The weft feeder comprises an electric motor for rotating a winding arm, a drum held stationary around which the arm winds up the yarn into even turns, forming a weft yarn reserve whose length is controlled by means of suitable sensors, and a yarn stopping device. The yarn stopping device includes a rod for engaging and stopping the yarn at the outlet of the feeder. The rod is movable between a withdrawn rest position and a projecting yarn stopping position in which its end moves into a cavity formed for such purpose on the drum periphery, close to the free end thereof. The drum cavity has mounted therein a plurality of bristles positioned transversely to the rod of the yarn stopping device, so that the rod may engage the bristles, crossing them at least partially, when assuming its projected position to stop the weft yarn.Type: GrantFiled: February 1, 1991Date of Patent: December 21, 1993Assignee: ROJ Electrotex S.p.A.Inventor: Bruno Maina
