Abstract: Rotary piston machine for compressible media, with rotary pistons sealed tight in a common housing and rotatable with one another in a controlled manner, the rotary pistons having a plurality of disk-shaped sections engaging in one another in pairs, whose thickness and/or diameter decreases in the direction of the pressure side, each disk having a surface area and a core area connected respectively by an interface area, the sector angles of the surface area and of the core area of a respective disk not being identical, the disks having various transverse profile contours periodically recurring along the piston axes and each disk being offset at an angle to the two adjacent disks of the same rotor in a such a way that these three disks have a common area section and form a chamber.

Abstract: Apparatus for enabling parts of the surface of a three-dimensional object (1) to be moved relative to each other. Applications include orientation of instruments on the surface of e.g. a satellite or a logic puzzle. Objects with eight external segments (1, 300, 500) are disclosed and it is shown how these can be adapted to form an object with thirty-two inter-changeable segments (400). Some embodiments may also be adapted to form an object with twenty-six inter-changeable segments (100, 200).

Abstract: Sensor for household appliances, in particular washing machines and dishwashers, comprising a housing 2 which comprises first and second housing fingers 8, 10 extending from a basis, a first optical element 12 being arranged in the first housing finger 8, a second optical element 14 which is arranged in the second housing finger 10 wherein a sensing beam 16 transmitted and received by the optical elements 12, 14 is propagating between the housing fingers 8, 10 external to the housing 2 for sensing of the turbidity of a cleaning medium at least partially surrounding the housing 2, and a temperature sensor 18 which is arranged in the second housing finger 10 in a greater distance from the basis 4 compared to the second optical element 14 for sensing the temperature of the cleaning medium.

Abstract: A method of making an electrical current sensor having an electrical conducting portion (6; 6a, 6b) of rectangular cross-section being surrounded, on three of its lateral faces, by a magnetic circuit portion (7) which has end portions (7′, 7″) having planar surfaces situated substantially in a plane of a fourth lateral face of the conductor portion (6), a magnetic field detector (3; 24; 26) being arranged opposite the fourth lateral face. The conductor portion (6) is made by photo-lithography and etching in a layer of electrically conducting material applied on a first surface of a flat support member (1; 1′; 1″) or on intermediate layers (8, 9, 10, 11) deposited on the support member. The magnetic circuit portion (7) is made by photo-lithography and etching in a layer of magnetically permeable material applied on the conductor portion (6) on the first surface of the support member (1; 1′, 1″) or of an intermediate layer (8).

Abstract: The invention concerns an apparatus for preparing a beverage from a capsule containing the product to be extracted comprising a water injecting device (3) including an injection head (18) connected to a water supply conduit (9), and a hydraulic system for displacing the injection head towards a capsule-holder (4) positioned beneath the injection head, the hydraulic system being connected to a piston water conduit (11) interconnected via a locking control valve (12) to a pump (2), which also feeds the injection head.

Abstract: The invention concerns a method which consists in maintaining the two ends (2, 4) of the bar (1) on the end supports (3, 5) of a frame (10), one of the ends (2) being maintained fixed, and in driving the bar in rotation. The invention is characterised in that it consists further in drawing the bar (1) while spraying a coat on the bar, the drawing of the bar corresponding to an elongation of about 0.2 to 0.001%.

Abstract: A door lock provides a restart lockout function for an electrical household appliance to prevent an automatic restart by closing the appliance door again after having been opened during operation of the appliance. The door lock comprises a locking device, which in a closed position locks the door and in an open position releases the door, and a restart lockout device, which in a release state enables operation of the appliance and in a lockout state prevents operation of the appliance. Upon a changeover from its closed position to its open position, the locking device brings the restart lockout device out of its release state into its lockout state.

Abstract: A device for displaying information, such as advertising, text, pictures or the like, comprising a wholly or partly transparent front plate (1) having an at least partly curved or bent cross section between a pair of essentially parallel side edges, and having first and second abutment members (4, 5) arranged along respective ones of the parallel edges at the concave side of the front plate (1), for retaining a display plate (6) in a fixed, curved condition between the abutment members, and a supporting means (30) for support of the front plate (1). The abutment members are gripping edges (4, 5) constituted by folded side edge portions of the front plate (1), and the supporting means consists of a support element (30) of a resilient material having opposite end portions (31, 32) shaped for releasable engagement with the gripping edges (4, 5) of the front plate (1), the element being arranged for resilient snap-in of the end portions (31, 32) to engagement with the gripping edges (4, 5) of the front plate (1).

Abstract: An electrochromic or photoelectrochromic device possessing the property of changing color under the effect of an electric voltage and/or of a variation in the intensity of a light radiation, this device comprising at least one cathode and one anode, at least one of these electrodes being constituted at least in part of a transparent or translucent substrate bearing an electrically conductive coating, and an electrolyte arranged between these electrodes, and an electric circuit connecting said cathode and anode, characterized in that at least one of these electrodes carries a coating constituted of at least one nanocrystalline layer of at least one semiconductive material, having a roughness factor equal to at least 20, and a monolayer of electrically active molecules or of an electrically active polymer, said monolayer being absorbed on the surface of this coating, and in that the device contains at least one auxiliary electrically active compound, possibly dissolved in the electrolyte, having the property of

Abstract: Safety equipment for a bed includes sheeting (14) arranged to be securable to a mattress (12) and an inflatable wall structure (10) secured to the sheeting. The inflatable wall structure is arranged so as to define an upstanding wall which, in use, in an inflated condition, serves as a barrier to someone falling out of bed and as a cushion which protect an occupant of the bed from injuring themselves against the structure of the bed. The wall structure may include lengths arranged to be collapsable along lines transverse to the length to permit the wall to concertina to adopt the profile of a profiling bed.
