A series of ortheses for the treatment of scoliotic deformities are each adapted for obliquely applying dynamic derotational forces on the thorax and lumbar spine of the user in opposite directions combined with a kyphosing action on the thorax and a lordosing action on the lumbar spine. The orthoses are designed in order that the correcting forces can be applied on the user's trunk with various d...

The method involves using a reference track image on board the train formed w.r.t. the track distance markers and determining the current distance covered on the track for correlation with the reference track image. The frequency spectra of acceleration measurements originating from a reference journey and the current journey are correlated for the on-board position determination. The frequency sp...

The present invention discloses a subbing coating composition for polyester films comprising: I a polymer A having attached to its backbone carboxyl groups and/or groups which form carboxyl groups upon hydrolysis and a polymer B having attached to its backbone -SO3X and/or -PO3XY groups, wherein X and Y are identical or different and denote an alkali metal, ammonium or hydrogen ...

A method and apparatus for inspecting articles such as printed circuit boards doubles the transport rate for the article under inspection, and modifies the manner in which acquired video images are processed to account for this change in rate. Primarily, this involves two modifications to existing video processing systems including a change in synchronization for obtaining the frames which are to ...

A flame-retardant composition useful in rendering polymers flame-retardant by copolymerizing with the starting monomers, which composition comprises a halogenated, phosphorus-containing polyester obtainable by reacting a polyhydroxyphosphonic compound (A) with a halogenated polycarboxylic compound (B) in such a ratio as to provide two or more hydroxyl groups in the resulting polyester, optionally ...

Two unique quick connect fluid coupling embodiments have a tube inner end (36) which does not contact a seal (42, 44) if the tube (22) is not fully connected. Preferably, a retainer retains the tube (22) within the bore of a housing (24). The retainer (30) is of the avalanche type such that a high force is required to insert the tube (22), and once this high force is overcome the momentum of the t...

The composite type card reader (11) has a shutter lever (28) for opening and closing a card inlet (13), a locking mechanism for locking the card by closing the shutter lever (28), and a lock releasing mechanism for releasing the lock by opening the shutter l...

A device for the receiving and advancing of tyre bead wires and for the transfer of the tyre bead wires to the magnetic disc of the bead setting device of a tyre building machine in green tyre production during automatic building of the said green tyre is provided with swivel arms (6), which can be swivelled inwards and outwards by means of a compressed-air cylinder (9) and which bring about a ten...

The method involves using a control system to vary the speed of the vehicle in a predefinable manner when the vehicle enters a section of track categorized as hazardous and there is no operator on board who can monitor the track in front of the vehicle and operate the brakes when required. The control system varies the vehicle speed so that the vehicle is brought to a standstill. The control syste...

Also disclosed and claimed are polyurethane foam compositions which include the surfactants, a method of making polyurethane foam using the surfactants, and polyurethane foam made by the me...

A new procedure removes infected animals, especially those carrying the agent causing BSE (bovine specific encephalomyelitis). The animals are slaughtered and the bodies further treated. The blood is intercepted (12, 13) and treated with a denaturant and colourant in a mixer (15). The mixture is stored in a collection vessel (19), to be transported away. Bled carcasses are opened to remove the inn...

Process for preparing a flexible foam by reacting a prepolymer having an NCO value of 3-15 % by weight, which is the reaction product obtained by reacting an excessive amount of a polyisocyanate with a polyether polyol or a mixture of such polyols, said polyol or mixture having an average nominal hydroxyl functionality of from 2 to 6, an average hydroxyl equivalent weight of from 500 to 5000 and a...

The invention relates to a process for the preparation of aqueous solutions and gels of chitosan in which chitosan and an acidic chelating agent are dissolved in water.
