A portable, stable motorless rope-climbing exercise machine comprises a stable support frame, a plurality of rope pulleys and rope guides mounted on the frame, an endless rope extending around the pulleys and guides to form a path which includes a vertically extending rope climbing portion, and hydraulic braking assembly coupled to the pulley system for controlling the rate of movement of the rope based upon the weight of the user when said user is climbing the rope.

A structure for encapsulating a connector assembly so as to provide a very high resistance between the conductors and between the conductors and ground is provided. The encapsulating structure includes a combination of at least two layers of epoxy resins with at least one layer having a dehydrating agent.

A fabricated platform includes a plurality of skeleton members having at least one pair of columns adapted to be disposed vertically on a mounting surface, a plurality of block members having a pair of throughholes adapted to be simultaneously passed through by a pair of columns of one of the skeleton members; and a plurality of plate members each having a plurality of pairs of holes formed therethrough. The two holes in each pair formed in the plate members are spaced apart from each other at a...

A workpiece detector for a sewing machine including a rotatable detecting lever in which small angular displacements at the end of the detecting lever, caused by differences in workpiece thickness, are multiplied mechanically causing the rotation of an electrical converter. Detectable output signals are generated such that overlapping of workpieces or the end of a workpiece may be detected during stitching. The length of the detecting lever is adjustable such that the detecting point may be vari...

A carding engine having a rotatable hollow carding cylinder (5). The inner surface of the cylinder is formed with a fluid-conveying pathway (18 to 21) in a pattern such that fluid circulated through the pathway will maintain the surface temperature of the cylinder substantially uniform. Means are provided for circulating fluid through the pathway in such a way that during operation the pathway is maintained full of fluid.

A method and device for creating uniform stitch lengths in an article being sewn by detecting actual feeding increments of the article using a sensor. With this information, the sewing or embroidery machine is controlled to provide generally uniform stitch lengths.

The present invention provides a sewing machine for positioning a line of stitches a predetermined distance from an edge of a workpiece. The edge tracing sewing machine includes a machine body with a reciprocable needle mounted therein. The needle is reciprocated between an upward and a downward position at which it pierces a moving workpiece, passing a thread therethrough. The edge tracing sewing machine also includes a plurality of illuminable units that communicate stitch positioning to a mac...

Provided is a faulty sewing detector that is, for example, mounted on an overlock sewing machine, with which an over-edge chain stitch is made in a state in which a body fabric and a sleeve fabric of a T shirt or underwear are overlapped with each other. The detector comprises a fabric twisting detecting sensor that detects a fabric twisting by determining the number of overlap of fabrics sewed which is disposed at a position corresponding to the fabric sewing area of a needle, and, behind a nee...

A confocal optical microscopy system for storing and retrieving optical information recorded in multiple layers in an optical disk. The invention includes a system utilizing the principle of confocal optical microscopy for accurately focusing a light beam onto a plane of a layer within a multi-layer disk. Optical information is thereby retrieved from the layer within the multi-layer disk. The invention also includes a method for recording optical data onto the multi-layer disk which comprises st...

A meter mounting is provided with contact jaws which are mounted on a thermally-conductive terminal bracket. The contact jaws are electrically insulated from the terminal bracket by means of a sheet of insulation which has good thermally-conductive properties.
