Patent EP-0552394-A1 (EP)
Inventor: BECKER MICHAEL DR
IPC: G02B26/00
Filed: 1992-01-24
Abstract: In a method and a corresponding apparatus for adjusting the wavelength in an optical device, a wavelength selective filter element (6), for example a Fabry-Perot etalon, whose wavelength characteristic depends on the angle of incidence (α min ) of the light beam (5) on the filter element (6) is arranged on a rotation axis (8) which can be rotated by a motor (9). The filter element (6) is mounted to the rotation axis (8) such that its surface normal (13) forms an angle (γ o ) with the axis (8). The rotation axis (8) itself is inclined relative to the axis (5) of the light beam passing through the filter element (6). When the axis (8) is rotating, the angle of incidence of the light beam (5) on the filter element (6) changes, resulting in a change of the wavelength of the transmitted beam. By rotating the axis (8), very small changes of the angle of incidence and thus of the wavelength can be precisely adjusted. The invention can be used in an external cavity laser comprising a semiconductor laser chip (1), a lens (4) and a grating (7). Rotation of the grating (7) by a drive unit (15) provides for coarse tuning of the output wavelength of the external cavity laser and rotation of the filter element (6) provides for fine tuning.

Abstract: The shower cubicle has a shower tray (1) with a cubicle wall (2) adjoining the shower tray, which wall on the one hand bounds the shower compartment and on the other hand forms an access opening to the shower tray. To simplify the assembly and for the tight connection of the individual parts, provision is made for the shower tray (1) to have an uninterrupted rib (9) in the region of the cubicle wall (2). The cubicle wall (2) consists of at least one self-supporting wall part (2) which has a continuous groove (13), which is complementary to the rib (9), on the narrow side facing the shower tray (1). The shower tray (1) and the wall part (2) are fitted onto the rib (9) in the manner of a tongue-and-groove connection, the wall part (2) having on its upper narrow side an identical rib (9) to that of the shower tray (1). <IMAGE>

Abstract: The fastening anchor has a plate section (1) and a pin section (2) protruding from it. These two sections are designed as a one-piece plastic moulding. A disc-shaped sheet part (4) is tightly welded to the plate section (1). A threaded rod (6) is screwed into the blind hole (3) of the pin section (2). The disc-shaped sheet part (4) is made of a plastic which can be connected in a sealing manner to a respective sealing layer (5). The fastening anchor is inserted with its pin section (2) into predrilled holes of a respective substrate and is, for example, adhesively bonded therein. The object to be anchored is to be connected to the threaded rod (6). There is thus a sealing layer surrounding the threaded rod (6), which sealing layer consists of the sheet part (4), the plate section (1) welded to it, and the pin section (2). This results in an impermeable anchor-fastening construction for surface seals, since the disc-shaped sheet part (4) is likewise connected in a sealing manner to the respective sealing layer of large area. The fastening anchor can be used for surface seals in the building and construction industry. <IMAGE>

IPC: C08F2/50
Filed: 1992-06-01
Abstract: Polymer dispersed liquid crystal (PDLC) films are prepared by ultraviolet curing of monomer/liquid crystal solutions with a copolymerizable photoinitiator instead of a traditional photoinitiator. As a consequence of this method of preparation, there is less initiator contamination of the separated liquid crystal phase in the PDLC films, since most of the copolymerizable initiator is trapped in the polymer matrix rather than in the LC phase, whether the LC is present as droplets or as part of a network or gel morphology. Because the LC phase in the PDLC is less contaminated by initiator, the following advantages are realized: (1) the LC phase has a wider temperature range and a higher clearpoint than PDLC films prepared with conventional photoinitiators; (2) the PDLC has a higher resistivity and better electro-optical characteristics than films prepared with conventional photoinitiators; and (3) the PDLC has increased device photostability as a consequence of initiator being trapped in the polymer matrix causing less PDLC degradation than initiator dissolved in the LC phase. This invention is applicable for the attainment of both droplet or network morphology PDLC films, including network gels.

Abstract: In a radio receiver for receiving a radio signal, a counter (32) counts an eventual intermediate frequency of an amplified signal based on a reference signal as a count datum. A frequency controller (27) controls a reference frequency of the reference signal according to the count datum. A reference oscillator (25) is controlled by the frequency controller to produce the reference signal. Receiving a radio signal by double superheterodyne, the radio receiver gives the eventual intermediate frequency to the amplified signal. In the amplified signal, the frequency controller suppresses an eventual frequency drift which results from frequency drifts of a first local oscillation and a second local oscillation. The radio receiver may be a single superheterodyne receiver.

Abstract: Substrate cubes (1) arranged in rows and columns and having the rooted seedlings (2) are fed to a mobile transporting and planting apparatus (5) having a plurality of workstations and means of transport between them. For the fully automatic planting out of the individual substrate cubes (1) at selectable intervals one behind the other and next to one another, the substrate cubes (1) together with the seedlings (2) are separated mechanically into longitudinal columns by separating discs (16) arranged in the form of a fan and at the same time fanned open somewhat. During further transport, the columns of substrate cubes are fanned open further, in guides, to the preselected intervals between the planting rows and are respectively transferred to conveyor bands (18) running at a higher speed, with the result that the individual substrate cubes of the fanned-open columns are separated at selectable intervals one behind the other. The substrate cubes, separated in this way to the selected planted intervals in the longitudinal direction within a planting row, then pass into planting shoes (19) and are planted out by these. <IMAGE>
