A connector block having a first slot extending from one face in a direction for receiving the edge of a circuit board, a second slot extending from a second face in a direction opposite to the first slot and past the first slot for receiving a nose with a ribbon cable wrapped around the nose, openings in the body portion between the slots and contact terminals confined within such openings such that insertion of the nose and ribbon cable into the second slot and insertion of the circuit board i...

An insulated electrical connection block, comprising a housing which encloses interconnected sleeve-shaped contact means, the contact means comprising a pair of abutting conductive sheets formed with respectively opposed radial grooves to define the sleeve-shaped contact means. The housing is formed in two cover-shaped halves which provide recesses adjacent the outer ends of the contact means.

There is provided a loader which is well suited for lifting heavy weight blocks and which is thus particularly advantageously usable in the assembling of blocks for building a ship. The loader body includes at least one beam arranged in a horizontal plane, and a plurality of separate pulley means are directly or indirectly mounted on the loader body in such a manner that these pulley means are arranged fixedly or movable to adjust the distance therebetween, whereby even when the center of gravit...

A right angle header block having a body and an assembly of stacked wafers to one side of the body. Disconnect contacts are confined within the body for engagement with the contacts inserted through openings on one side of the body. L-shaped lead wires extend from the disconnect contacts along interfaces of a stacked wafer assembly and then through the thickness of the assembly to the edge of the bottom wafer. The wafer assembly snaps into the body and is accurately located relative to the body.

A paving block having sides which are shaped to provide an interlocking tooth engagement between the complementary sides of adjacent blocks when laid. Such engagement counteracts shifting of the laid blocks when loads are applied thereto.

Glazing blocks for clamping a window-like panel within a frame having a base portion arranged outwardly of the peripheral edge of the panel, and an inwardly directed shoulder portion against which the panel edge is abutted. The block has a base rested upon the frame base portion, an inwardly directed flange opposing the frame shoulder portion for clamping the panel therebetween, and a wedge-like panel edge engaging tongue portion arranged between the peripheral edge of the panel and the frame ba...

The invention concerns an adhesive block of hot-melting material for an adhesive dispenser in which the block advances along a feed passage under the action of pressurised fluid, is melted and is dispensed as a liquid adhesive, the block having one or more flanges formed on its body, the or each flange being shaped and dimensioned to be capable of serving as a piston face for the direct application of pressurised fluid thereto, whereby the block can be advanced along the feed passage in sealing ...

A ram block for a blowout preventer which can be used successfully in a hydrogen embrittlement environment. The body of the ram block is made of an alloy having an upper hardness level of Rockwell 22 on the C scale (Rc 22), and is provided with an inner supporting edge of a soft, relatively stress-free, workhardenable alloy having an upper hardness level of about Rc22 which is capable of rapidly hardening on slight deformation at least about Rc 35 and upon engagement with and deformation by a to...

A hardened metal block is precisely machined, ground and lapped so as to include a number of stepped surfaces that are accurately dimensioned from a base surface. The base surface is of precision flatness in order to be wrung into adhesive contact with a companion block of precision measurements. A portion of the calibration block is removed to provide access to the companion block as a reference point.

The invention concerns an adhesive block of hot-melting material for an adhesive dispenser in which the block advances along a feed passage under the action of pressurised fluid, is melted and is dispensed as a liquid adhesive, the block having at its rear end a flange shaped and dimensioned to be capable of serving as a piston face for the direct application of pressurised fluid thereto, whereby the block can be advanced along the feed passage in sealing engagement therewith.
