Inventor: KUMCHER FELIPE
IPC: E04B1/19
Filed: 1988-06-14
Abstract: A node-and-bar space-frame structure comprising just two different types of separate elements relatively simple to manufacture and easy to assemble and eventually dismantle, providing thus increased economy all round. The node element (11) includes eighteen connector lugs (37), each featuring a tongue-and-groove shape (41) cut out from a cylinder. The bar element (13) has at each end thereof matching connectors (39) of the same shape and size as the node connectors, one end (29B) of the bar being rotary. A bar-and-node connection is established simply by pressing the matched connectors into each other such that they latch firmly in place. A sleeve-clamp (51) on each bar end slides into place over each connection to secure it against accidental unlatching. The eighteen node connectors are integrated with three orthogonal inter-­lockable disk-shaped bodies (15), two of which are manufactured as a pair of identical full-disk units (15A, 15B) whilst the third (15C) is formed by a pair of identical half-disk units (17). Plastics or metallic materials may be used according to applications.

Abstract: A variable magnification optical system for a copier has a movable lens (10) of fixed focal length for projecting an image of an original document with a desired magnification within a predetermined range, e.g. 0.64 to 1.54, onto a photoreceptor(6). The lens 10 is fixed on a carriage (12) which is slidable along an elongate cam member (13) inclined to the optical axis. The lens is coupled to a cam follower (11) which is slidably mounted on the carriage 12. Cam member (13) has an arcuate camming surface (20) against which the cam follower (11) is urged so that the lens (10) describes an arcuate path as the carriage (12) travels along the cam member (13) enabling the top edge of the original document to be registered with a datum on the photoreceptor (6) for all magnifications. The camming surface (20) is extended beyond that necessary to achieve the predetermined magnification range for the lens, and the cam member (13) is movable relative to the cam follower (11) to alter the portion of the camming surface with which the cam follower cooperates. This makes it possible to compensate on an individual basis for manufacturing tolerances in the focal length of a particular lens used and thereby maintain top edge alignment. In an example of a two dimensional cam the cam surface is extended at both its ends, and the cam member is movable longitudinally (see Figure 2). In an example of a three dimensional cam the camming surface comprises a plurality of different arcs of the same curve disposed sequentially in adjoining relationship transversely to the plane of the curve and the cam member is movable at right angles to the longitudinal axis.

Abstract: A coiled heating element is manufactured by providing a coiled element (1) of bare resistance wire (2) in which the coil pitch is not greater than twice the cross-sectional dimension of the wire. The element (1) is stretched by an amount permitting recovery to its original configuration and an electrically insulating particulate material (3) is applied to the stretched element. The stretched element is then allowed to return towards its original configuration thus trapping particulate material between adjacent coils of the element and the element is heated so as to oxidise the surface of the wire.

Abstract: A method is disclosed for printing and applying two differing labels each including human readable information onto substantially rectangular packages in a manner such that the information on both labels is readable from one of at least two selectable side edges of the packages. A first label is applied in a selected physical angular orientation by a first label applier such that the human readable information thereon can be read from one selected side edge of the packages. The human readable information for a second label is stored as digital data which is assembled in a print buffer such that when it is printed onto the second label the information can be read from the same selected side edge of the packages once the second label is applied in a fixed physical angular orientation by a second label applier. In accordance with the method, human readable information printed upon two labels applied to packages can be made to read from the same side edges of the packages even though the first one of the labels is rotated to obtain a selected physical angular orientation and the second of the labels is not rotated but applied to the packages in a fixed physical angular orientation.

Abstract: Lance for injecting refining oxygen from above into baths of metals or of ferrous alloys contained in metallurgical vessels. In its end part the lance comprises a Laval tuyere defining in the direction of flow of the gas firstly a converging region, then a cylindrical throat and finally a diverging region. It further comprises a substantially cylindrical movable central regulating body which can be moved forward or back axially in the neck region of the Laval tuyere. The nose of the central regulating body has a special profile which, together with the outer coaxial cylindrical wall of the Laval tuyere, defines a diverging region which causes an expansion of the gas stream. The profile of the nose of the movable central body and that of the converging portion of the Laval tuyere are at least approximately complementary. The characteristics of the gas stream are modified through changing its flow profile by axial movement of the nose of the central regulating body.

Abstract: A single crystal turbine blade (10) has a portion of its attachment section layered with a fine grained, polycrystalline alloy (34). The blade is prepared by casting a single crystal body with an undersized attachment section (24), and then layering the attachment section with the polycrystalline superalloy to form a composite structure. Layering is preferably accomplished by plasma spraying the body with the superalloy, and hot isostatically compacting the sprayed superalloy to minimize porosity. The composite structure is then heat treated to develop an optimized microstructure in the dual alloy attachment section. The polycrystalline material in the attachment section may be machined to a firtree shape for mounting in a turbine wheel. The resulting turbine blade has improved life resulting from reduced low cycle, low temperature fatigue susceptibility of, and crack growth in, the composite attachment section.
