Patent DE-3844487-C1 (DE)
Title: Anchorage for shuttering panels for embedding supporting load-bearing members in concrete
IPC: E04G17/04
Filed: 1988-12-31
Granted: 1990-02-15
Abstract: An anchorage (1) for shuttering panels (2), which serve for embedding supporting load-bearing members (3) in concrete, in particular in underground work or tunnel construction, exhibits an intermediate piece (6) which can be opened or is separated in a longitudinal plane (E) and has a threaded part (7), directed away from the load-bearing member (3) in the use position, for a shuttering tie rod (8). The intermediate piece (6) has a retaining head (9) which can be opened by virtue of its separation and has an inner opening (10) which, in the use position, engages around an undercut (5) or a web (4) of the load-bearing member (3). Shuttering panels (2) can thus be fixed on the load-bearing member (3), which is to be embedded in concrete, such that they withstand the concreting pressure without a supporting means being necessary on the outer side, directed away from the concrete, of the shuttering panels (2). <IMAGE>

Abstract: The current regulator (4), inserted between a DC battery (1) and an AC load (11), uses a controlled semiconductor bridge (5) across which the AC load (11) is connected in series with a choke (6,7).  The latter is divided into main (6) and auxiliary (7) chokes connected in series, the auxiliary choke inductance ensuring that it's effective when the main choke (5) is saturated. The main choke (6) may have two individual coils wound around a common core, each lying in the current path for the AC load (11). ADVANTAGE - Reduced instability.

Filed: 1991-02-21
Granted: 1992-06-11
Abstract: The optical interference microscope has a sample illumination device (10, 12) an objective lens (26) and a viewing lens (40). A interferometer (32) is installed in the light path between the lenses. An image converter (42) behind the viewing lens has a matrix of LCD elements and is coupled to a computer (44) allowing the strip pattern obtained at the image convertor to be converted into contour height differences, represented numerically or graphically. The strip pattern can be optically enlarged, e.g. via adjustment of the viewing lens. ADVANTAGE - High resolution and improved light intensity.

Title: Car seat cover fastener with holding loops - has anchor plate tongue extending beyond plate aperture and deflecting under pressure
IPC: B60N2/58
Filed: 1991-06-05
Granted: 1992-09-17
Abstract: The fastener for a vehicle seat cover (8) has a hollow anchor plate (17) inserted into the underside of a gap (5) in the squab cushion base (2, 3). A stirrup, suspended from a securing loop (9) on the cover, is depressed through the cushion (2) and the anchor plate, pushing aside a tongue (16), formed from the anchor plate. The tongue then springs back against the rim of the anchor plate, preventing the release of the stirrup. A compressible slot for easing insertion of the anchor plate is pref. provided, and the tongue is typically S-shaped in the longitudinal sense. ADVANTAGE - Low-cost cover fastener with simple mechanical application.

Title: FET mfr. using dielectric etching for gate formation - applying two dielectric layers of specified material for successive spacer formation to define very narrow gate width
IPC: H01L21/335
Filed: 1992-04-02
Granted: 1993-07-01
Abstract: During FET manufacture, a channel layer (2), a contact layer (3) and an insulation layer (4) made of SiN, SiO2 or SiON are formed on a substrate (1). For gate formation, a dielectric layer of the same material is formed on the insulation layer for an etching process. Spacers (5) are formed on each side to define the width (8) of the gate within the contact layer. A further dielectric layer (60) is then formed in a second stage, to form further spacers (6) which define a reduced gate width (7). Source and drain formation follows. The length (9) of the region over which the insulation layer (4) is removed is at least 5 microns. ADVANTAGE - Very short gate widths can be obtained using optical lithography.

Title: Folding stool
Inventor: FRENZEL MANFRED
IPC: A47C9/10
Filed: 1993-05-19
Granted: 1994-11-10
Abstract: The invention relates to a folding stool having at least three legs and two supporting arms for a seat comprising a flexible web, which are articulated on a central junction plate, the web being provided at each of its ends with a bar and an eye which is located in the centre of the bar and can be hung into a corresponding notch at the free ends of the supporting arms. The connection between the seat and the supporting arms is, however, problematical. For this reason, the invention provides, in the case of the folding stool, for the bar to be inserted into a loop formed at the ends of the web and for the eye to be formed by an opening in the loop which exposes the bar, so that the bars can be hung directly into the notches of the supporting arms.
