Title: Outlet attachment
IPC: F15D1/08
Filed: 1989-02-09
Abstract: An outlet attachment (1) has a connection (2) for the outlet (23) of a fitting and has a change-over device (4) for the purpose of varying the liquid flow rate. For this purpose, housing parts (7, 8) which are connected to one another by an adjusting thread (9) and the spacing of which relative to one another can be adjusted and which can be adjusted relative to one another by means of a combined rotary and linear motion are provided. The housing part (8) on the outlet side is connected via connecting ribs (11) that leave flow openings free between them to internal functional components whose position is to be adjusted. A central flow passage (13) formed by a sleeve (12) can be provided with a screen (5) or a flow-rate limiter inserted in it. Adjoining the sleeve radially to the outside is an annular bypass passage (6). By means of the combined rotary and linear movement, the sleeve (12) can be moved into the bypass-closing position, in which flow takes place only through the sleeve opening. In the other position, the bypass passage is open and forms an additional flow passage. The outlet attachment can be used, for example, as a jet regulator with a filter that can be connected up, as a jet regulator with varying flow rates or as a jet/shower changeover device (Fig. 1). <IMAGE>

Patent DE-3926053-A1 (DE)
Inventor: CARLIN DONALD BARRY
IPC: H01S5/187
Filed: 1989-08-07
Abstract: A surface emitting laser comprises two lasing regions 32a, 32b separated by an optical grating which causes the light output from the lasing regions to be emitted normally to the surface. A plurality of such lasers are laterally aligned and coupled together and also have their light output signals combined. This results in greater phase and frequency coherency and narrower and reduced amplitude sidelobes. Preferably, not more than two lasers are longitudinally aligned along the same axis for still greater coherency compared with adding the light output signals of more than two longitudinally aligned lasers. The lasers can be of the DH-LOC type or of the QW type. <IMAGE>

Inventor: PRATT VANON DAVID
IPC: B23K26/00
Filed: 1989-12-20
Abstract: An article eg a turbine blade is fabricated by depositing a succession of overlying beads (26) of a material (48), the pattern and position of the beads being assigned the proper characteristics of the corresponding section of the desired component. Shape definition is accomplished by characterizing the component as a series of sections or slices having the thickness of the bead, and programming a computer-controlled deposition head to deposit a succession of beads with the respective patterns and positions. Deposition is preferably by precision laser (58) welding. Complex shapes having properties comparable to properties of forged or cast material are readily prepared. The material used in successive beads may be varied, producing a component of graded composition to achieve particular properties in various regions. <IMAGE>
