Abstract: A tongue and buckle fastener for a safety belt harness has a tongue 1 with a radiused head portion 3 shaped to mate with a recess 8 in an ejector 17. A latch plate 20 moves at right angles to the direction of insertion of the tongue 1 to engage behind the head portion 3 of the tongue 1. When the tongue 1 has been ejected, the latch plate 20 engages in a groove 28 in one side face of the ejector 17 and overhangs the recess 18 in the ejector 17. When the tongue 1 is inserted, it engages corners 29a and 29b on the latch plate 20 which overhang the recess 18 so as to lift the latch plate 20 out of the groove 28. If a member of any other shape than the tongue 1 is inserted, it cannot engage with both corners 29a and 29 b simultaneously. Consequently only one side of the latch plate 20 is lifted and the ejector continues to block further insertion of such a member.

Abstract: Disclosed is an improved method of fabricating boron fiber and aluminum matrix composite structures, especially gas turbine compressor blades having titanium metal skins. Titanium skins and boron aluminum composite cores are preformed by gas pressure and hard dies prior to hot pressing. The composite sheets of the core are preformed with the use of expendable carrier sheets, which hold the stacked sheets firmly as both the carrier sheets and composites are shaped through moderate temperature and gas pressure against a hard die. The preforming permanently shapes and lightly bonds the composite sheets. The skins are preformed in an analogous process using gas pressurization of a metal envelope into die cavities. The skins and composite core are then hot pressed in hard dies to form the finished part.

Abstract: Suspended from a carriage that straddles a standing seam, in which the upper portions of adjoining upright flanges are interlocked, is a vise having a pair of normally spaced jaws with a short length of the standing seam between them. One of the jaws is rigidly connected to the carriage, but the other jaw can be moved toward and away from the first jaw by a fluid pressure cylinder supported by the carriage. The movable jaw is moved toward the other jaw periodically to compress and close the interlocked upper portions of the seam. Each time the jaws are separated the carriage can be moved along the seam in order to close an adjoining length of the seam. Preferably, the carriage is moved along the seam automatically by means of motor-driven rollers that frictionally engage the standing seam. The rollers are rotated to move the carriage only while the vise is released from the seam.

Abstract: The process employs ion implantation for precise dopant control. The implantation is performed into a thin layer of amorphous silicon covering the emitter and collector opening. The implantation energy is chosen so that the damage is confined to the amorphous layer. Since the deposited silicon layer is to be removed by subsequent processing, its thickness must be carefully controlled. The layer is preferably deposited by a sputtering technique which allows the necessary uniformity and reproducibility of the layer thickness. Furthermore, the sputtering process with its energetic ions provides a reproducible quality interface which is of critical importance for a diffusion source. With such a source, the diffusion into the single crystal silicon extends about the same distance in the horizontal as the vertical direction. This provides the greatest possible horizontal displacement of the junction under the passivating silicon dioxide layer.

An advantage of this is that the injection site is positioned on the support tube in relatively unstressed condition. Furthermore, the skirt portion may define on its inner surface a plurality of sealing rings adapted to sealingly bear against the support tube.

Abstract: An infra-red radiation detector element and its manufacture. The detector element has a mesa (31) of infra-red sensitive material, e.g. cadmium mercury telluride, with separate metal electrodes (64 and 55, see FIG. 17) formed on side-walls of the mesa (31) from a metal layer 33. This permits a significant proportion of the current flow occurring between the electrodes (64 and 55) in operation of the element to pass across the bulk of the mesa (31) between its side-walls and not adjacent its top surface where the carrier recombination velocity may be higher. The mesa (31) is formed by ion-etching using a masking layer (24) e.g. of photoresist, and this permits reproducible etching over a uniform depth and the obtaining of a topographically rough surface to which the subsequently-deposited metal layer (33) can have good adhesion. The electrodes are formed from this layer (33) by a lift-off technique using the same masking layer (24).
