Patent EP-0573369-A1 (EP)
Inventor: GUPTA MOOL CHAND C O EASTMAN K
IPC: G11B7/135

Abstract: A dual diffraction grating useful in optical disk heads comprises first and second light diffracting surfaces of identical pitch and depth, wherein the diffraction grooves of the first and second diffraction surfaces are angularly oriented with respect to one another. Incident light beams are diffracted into first and second components with the first components being TM polarized components and the second components being TE polarized components. Upon emerging from the dual diffraction grating, the first and second components diverge with respect to one another because the first component is substantially transmitted through the diffraction grating without diffraction while the second component is diffracted. The initial diffraction by the first grating causes the TE component to diverge away from the TM component while the second diffraction grating diffracts the TE component back toward the TM component so as to diverge therefrom by only a slight angle of, for example, about 0.1° to 3.0°. In use, the two components emerging from the dual diffraction grating are focussed on photodetectors to develop reproduction signals and tracking and focus error signals. In a preferred embodiment, the first diffraction grating is etched in a first substrate, and the second diffraction grating is etched on a second substrate. The first and second substrates are then bonded to one another with a layer of optical adhesive. The two gratings are displaced by 0.1-5° with respect to each other.

Abstract: An extendable and collapsible seat cushion (10) manufactured from a unitary piece of foam (18). Channels (16) are molded into the foam (18) perpendicular to the length of the seat to allow for compression of the overall length of the seat cushion. Further, channels may be molded into the foam in a direction parallel to the length of the seat cushion to allow for compression of the seat cushion in the lateral direction as well. The channels have angular recesses (16a) near the surface of the cushion (18) to provide a home for compression hinges (19) created by connective foam and cloth disposed between segments of the cushion. A telescoping support (30) frame is provided to assist in the compression and extending of the seat cushion (18). This support frame (30) may be telescoped manually or with assistance by power.

Date Aug. 19, 1993.A water heater has a gas inlet (8) for a mixture of gas and air and an inlet for a fluid (2) to be heated. The gas-air mixture passes through a combustion chamber (11,18) which is at least partly surrounded by at least one fluid chamber (4,7) filled with the fluid (2). The exhaust gas leaving the combustion chamber(s) (11,18) passes through an exhaust gas heat exchanger together with the fluid (2). Here there are two combustion stages, the first (16) being a catalytic gap burner (11) and the second being a monolithic burner (18,19). Owing to the two-stage arrangement, about 80% of the combustion gas is burned in the combustion stage (16) while the remainder is consumed even at the low partial pressures in the second combustion stage (20) virtually without any residue, and especially without emission of NOx.

Abstract: Des objets géométriques consistant en des points, lignes, courbes, surfaces et solides sont définis et élaborés dans un système retenant et utilisant les relations et les dépendances entre objets dans une structure de données de graphe dirigé (digraphe). Le principal avantage du système est une mise à jour automatique du modèle, préservant les dépendances, lorsqu'un objet sous-jacent est modifié. Des types divers de courbes et de surfaces paramétriques et des niveaux divers de dépendance sont aisément appuyés par une structure de programme récursive. Les difficultés d'intersection surface/surface et d'épure sont évitées principalement grâce à des entités nouvelles permettant d'élaborer des unions précises et durables entre objets de surface. L'exemple de représentation (fig. 27) du dessin d'un voilier de plaisance montre six objets de surface de type différent avec leurs relations de dépendance définies. Les plans définis par la coque (271), le pont (272), l'avant de la cabine (273), le côté de la cabine (274), l'arrière de la cabine (275) et le sommet de la cabine (276) se coupent à des liaisons (278, 279) qui sont précises et durables. La relation à ses liaisons et le positionnement relatif des surfaces sont automatiquement préservés lorsque le modèle est mis à jour par modification de l'une de ces surfaces.

Each of these hinge leaves has at least one angular appendage running across the front edge of the associated door panel to a point near the door's arris, and the bores for the hinge pins are provided in the staggered knuckles of the hinge leaves.

Abstract: In the case of electric shock protection which is provided especially for panel distribution busbars (3) in low-voltage distribution cabinets, a flexible, electrically insulating covering profile (22, 22'), which essentially covers the contact bar of the side in each case, extends on both sides of the contact bar (14), along said bar. The covering profile (22, 22') is arranged in such a manner that it prevents the contact bar (14) being touched accidentially by a finger, but a terminal contact (9) which bears like a clasp against both sides of the contact bar (14) can, however, be pushed from the front onto the contact bar (14) with the two covering profiles (22, 22') being locally and automatically forced apart from one another. The force which is required to push the terminal contact (9) on can be reduced by means of a covering strip (21), which is additionally arranged on the front of the contact bar (14) and has a cross-section which tapers towards the front. <IMAGE>

Abstract: Mouldings produced from rigid polystyrene foam or polystyrene particle foam are used for insulation purposes. It has been found that rigid polystyrene foam having a density of less than 20 kg/m<3> has a higher thermal conductivity than rigid polystyrene foam having a higher density. The invention has the object of providing a moulding made from rigid polystyrene foam which has a density of less than 20 kg/m<3> and a favourable thermal conductivity. This object is achieved according to the invention by providing the rigid polystyrene foam with an athermanous material. The consequence of this is that corresponding mouldings having a density of less than 20 kg/m<3> have a thermal conductivity which is no greater or not significantly greater than the thermal conductivity of rigid polystyrene foam having a density of about 40 kg/m<3> with relatively low thermal conductivity. The invention is particularly suitable for sheet-like mouldings made from polystyrene particle foam for insulation in the construction (building) sector.
