Knitting elements for a single cylinder knitting machine adapted to be reciprocatingly mounted in the grooves of the dial knit loops and to transfer the loops to the needles. The knitting elements comprise a pair of blade-like members movable with respect to each other. One of the members has an operative end forming an upwardly directed finger having a forward tip and a front and rear yarn receiving beds on its upper edge, the second of the members has an operative end forming a downwardly dire...

Components for forming a drawer or other tray-like structure comprise hollow wall members, conveniently plastics extrusions, defining mortice sockets in their ends, and corner or front connecting members, conveniently plastics mouldings, having tenons engageable in said sockets and retained by triangular or similar detents which snap-engage with complementary apertures in walls of the sockets. The detents are carried on the free ends of resilient tongues, which free ends are directed away from t...

A flooring element having a moulded body and a partially raised surface which is of a material having a relatively high coefficient of friction, preferably the elements are provided with interlocking lugs so that a floor covering can be built up from a number of them.

A plurality of elements with dimensions forming a series of the FIBONACCI-type having a relationship of 1/2 .+-. 1/2 .sqroot.5. Such elements are suitable for economizing storage space and manufacturing costs as only a limited number of different sizes are to be kept in stock.

Electrically conductive sealing elements include a resilient grommet portion and an electrically conductive portion imbedded in a portion of the grommet so as to provide EMI protection and/or an electrically conductive path from a workpiece to a panel into which the grommet can be inserted.

Compressive and tensile structural elements are disclosed having an enclosure with walls surrounding a cavity. A non-compressible material is disposed in the cavity. The walls are shaped such that a force tending to compress or elongate the element by a first deflection causes an amplified second deflection of the walls into the non-compressible material. The second deflection exerts a compressive force against the non-compressible material, resulting in a resistance to the first deflection and ...

In a photothermographic element comprising a photosensitive layer containing an organic silver salt, a silver halide, and a reducing agent on one surface of a support, and a back layer on the other surface of the support, the outermost back layer is based on a polymer latex binder, and the back layer contains a dye of formula (I) satisfying a specific maximum absorption wavelength relationship. The element produces an image with high Dmax, ultrahigh contrast, satisfactory resolution, and minimiz...

A structural I-beam formed of upper and lower surfaces with a means connecting the upper surface to the lower surface. The beam has a plurality of structural elements placed along the upper as well as lower surface. Each of the structural elements themselves having both compressive and tensile structural elements formed as a unit adjacent one to the other. The compressive structural element of the structural element serving to dampen any compressive forces acting on the upper surface of the beam...

Thermoelectric elements of both P-type and N-type lead tellurides having unique characteristics including, particularly in the case of the P-type, a figure-of-merit 90% above that of the best commercial P-type element, are produced by a new process involving as key steps chill casting, cold pressing and sintering to 85-90% theoretical density under protective atmosphere.

Building elements with matching side surfaces for fitting together to form constructions of varying shape, said building elements having the same length (L) and each having two opposite, equiform, flat, parallel end surfaces and at least three flat, rectangular side surfaces extending between said end surfaces to effect said matching of the side surfaces, the cross-sectional surfaces of the building elements each having a size which is a multiple of a triangular area of the size a.sup.2/2, and t...
