Improved pharmaceutical salts of amlodipine, particularly the besylate salt, and pharmaceutical compositions thereof. These salts find utility as anti-ischaemic and anti-hypertensive agents.

A wiring duct (10) has an essentially rectangular cross-section with an open front side for the insertion and removal of electrical leads (1,2). Longitudinal strips (11), with an L-shaped cross-section, are integrally formed parallel to the base of the duct on the open side of the wiring duct (10), the shorter limb (12) of which strips (11) is directed towards the base of the duct. The open side o...

Nitride and carbide powders by a carbothermal reduction route and, if appropriate, nitration of metal oxides capable of being employed especially for the manufacture of ceramics and having a specific surface of between 30 and 250 m<2>/g. Process for the manufacture of powders comprising the following stages: a) from metal oxide or oxides with a particle size of less than 10 mu m, a binder generati...

A mineral wool body suited for use as a sound insulating body having the ability of damping or absorbing both high frequence and low frequence sound, and in which at least the largest portion of the surfaces of the mineral wool body which are exposed to said high frequence and low frequence sound is covered with a binder in such amount and by such application method that practically all surface fi...

Air duct for air distribution systems, for instance a ventilation duct, which is assembled by a plurality of elongated duct sections (1) of incombustible material. Each duct section includes an elongated duct section (5, 6) with an opening (29) which is oriented parallelly along the longitudinal axis of the duct element, and which has the same length as the duct section, the opening being closable...

The invention relates to a process for the separation of L-leucine and L-isoleucine. The process is carried out by subjecting a mixture of leucine ester, and isoleucine ester (or a mixture of leucine ester, isoleucine ester and valine ester) to an esterase catalyzed hydrolysis resulting in a selective hydrolysis of the leucine ester. The pure L-leucine can be isolated from the reaction mixture by ...

Each car controller (10) in a multicar elevator system provides two serial asynchronous full duplex I/O channels to communicate with the next and previous car controllers. These two channels allow the transmission of a message in two opposite directions (32,34) on a communications ring. A single interruption of the ring, by a interrupted transmission line or a disturbed car controller for example,...

The upper weather0) and side parts (4,5) of the protection fit closely around a vehicle which is standing in a loading bay, the upper part being formed by a sealing component (10) in the form of a completely smooth roof sheet (11) of textile material. The upper part (10) is unrolled or rolled up by means of a drive unit.

A support stirrup part (10) is provided, from which a line carriage (11) is releasable for re-use in conjunction with another stirrup. The stirrup part is approx. upwardly and downwardly U-shaped, and has two downwardly directed arms (12,13) together with an upwardly directed fixture lug (14) with a hole (15). It also has a clamp unit (16) in the form of a stirrup (17) which is activated by a scre...

An interconnecting arrangement for one end of a fluid- conveying pipe and a connecting pipe or a fitting comprises a connecting nut 4 which, by means of a locking member 5, can be mounted on a cover plate 1 provided with a cutout 2. The connecting nut 4 has a flange part 4b which is guided through the cutout 2 and provided with a groove 4c. For play-free mounting of the connecting nut 4 on the cov...

The inductance of each toroid coil is calculated so that it is the same as that of others in the same pair, and together the resistance corresp. to the AC current period count is sufficiently strong even to protect against strong current for diodes or switches in the event of short-circuiting. Since the winding of the toroid coil passes one turn around the core, the two must be positioned with lik...

The present invention concerns a tracer composition which gives a low content of free electrons in the flame and is therefore especially suitable for use together with proximity fuses. The tracer composition has a maximum combustion temperature of 2000 K and includes, in addition to binder and fuel, ammonium perchlorate as oxidizer and, if appropriate, a small amount of an iodine compound, and the...
