The invention relates to a process for the production of flameproofed polystyrene bead foams containing reclaim, which comprises coating comminuted recycled polystyrene foam with at least one flameproofing agent and fusing the coated pieces together with freshly produced, prefoamed polystyrene beads to give moldings, and to products produced by this process.

A prosthetic component is provided for a condylar joint. The prosthetic component includes a platform having a bearing surface and a pair of side walls. The side walls include a pair of concave surfaces which face one another and define arcs of the same right circular cylinder. The prosthetic component also includes a plastic bearing having a bearing surface slidably engaged with the bearing surfa...

A knee joint prosthesis includes a femoral component, a tibial plateau and a tibial bearing member. The design and geometry of the articulation surfaces of the condylar elements of the femoral component and tibial bearing member is such that contact area between the articulation surfaces is maximized both in perfect alignment and in malalignment conditions. Moreover, contact stresses placed upon t...

L'invention concerne un appareil portable et non implantable pour permettre à un patient de s'administrer. à sa demande. des doses successives d'un liquide sans que le délai entre deux administrations successives puisse être Inférieur à une valeur de consigne. L'appareil comprend un réservoir de liquide (7) formé dans un piston (3) qui peut être poussé dans une chambre (1) pour expulser par une so...

A client-server network enables interconnection to both the Internet and switched network. In response to a received client service request, a connection is established over the Internet between a client and a server. Client information transmitted from the client to the server over the Internet connection is used to enable the server to provide the requested service by establishing a switched net...

The invention relates to a mobile communication entity, which combines several mobile communication networks, which can be part of different mobile communication systems (31, 33, 34, 44), and in which a mobile terminal can operate and establish connections to a receiver via said mobile communication networks. The mobile terminal selects a first mobile communication network based on a certain crite...

Novel oligonucleotide analogs of the formula (I) are described, in which A, B, D, G, L, P, Q, Q', R5, R6, X, Y, Z and n are as defined in the description, which have useful physical, biological and pharmacological properties, as well as a process for their preparation. Their application relates to use as inhibitors of gene expression (antisense oligonucleotides, ribozymes, sense oligonucleot...

Target-identification arrangement with an imaging sensor, a signal-processing coupling and an evaluation coupling with a computer for grey scale value analysis of the output signals from the imaging sensor, the signal- processing coupling containing a threshold detector for lightness transitions and for the local extreme values, a sorting based on three words - light/desired/dark - taking place in...

A frequency hopping radio communications system has a plurality of radios each incorporating a transmitter and a receiver. When a radio is not transmitting or receiving, a switch switches it into a mode in which it monitors the signal strength in each of the available hop channels so as to assess the level of interference, and selects a subset of the total number of channels, those having the lowe...

A pipeline coupling comprises first and second substantially annular connecting pieces (2,20) at each end of a length of pipe, an internally threaded nut (14) on the first connecting piece (2) and a corresponding external thread (27) on the second connecting piece (20), and a sealing ring (28) for location between adjacent ends of two lengths of pipe to be connected, a sealed connection between th...

A microwave oven in which a plurality of projections are formed on an interior surface of a cavity for reflection and distribution of microwaves. The plurality of projections are dispersedly arranged so that neighboring projections do not contact each other. With this arrangement, microwaves can be efficiently distributed within the cavity, since the interior surface of the cavity does not have an...

A cover fitment for mounting on a vehicle battery case which is itself attached to a chassis member (12) at the side of eg an articulated tractor unit (10) is moulded as a one-piece component (21, 22) in high impact on tough plastic eg polystyrol, ABS or glass-reinforced nylon. The fitment (21, 22) is supported in a fixed cradle (not shown) on the chassis runner (12) using the spigot projections (...

This invention presents planar solid-state membrane modules for separating oxygen from an oxygen-containing gaseous mixture which provide improved pneumatic and structural integrity and ease of manifolding. The modules are formed from a plurality of planar membrane units, each membrane unit which comprises a channel-free porous support having connected through porosity which is in contact with a c...

The tray (1) has between 2 and 200, pref. between 4 and 20, complete or partly removed sockets (4) on its upper side into which bottles (2) can be placed. They are arranged in rows between its opposing sides. The tray also has an equal number of shapes on its underside, which resemble bushes or rings, and which can accommodate bottle caps (9). The tray rests on bulges or mounting rings (11), on th...
