An improved mobile X-ray unit has a counterweighted articulating X-ray tube support arm that allows positioning of an attached X-ray tube virtually without the need for moving a supporting carriage. The improved mobile X-ray unit also allows the X-ray tube to be locked to the supporting carriage during travel and the articulating X-ray arm includes several electro-magnetically actuated disk brakes...

A method for granulating a stream of molten metal which is caused to fall from a launder or the like down into a liquid cooling bath in a tank. The metal stream is divided into droplets in the liquid cooling bath, which solidify and form solid granules. A substantially uniform flow of cooling liquid is caused to flow from one of the side walls in the tank substantially perpendicularly against the ...

A solid surface modifier is provided by means of a composition containing a highly dispersed hydrophobic powder, a silicone liquid, a solvent, and, optionally, an adhesive. The modifier is effective in imparting water repellent, anti-fouling, anti-icing, anti-corrosive, and anti-friction properties to various surfaces.

A method and a device for regenerating clock rate information in which data is intermediately stored in a memory (1) to which the data is read at a first rate (C1) and out of which the data is read at a second rate (Cp). The difference (np, np') between two levels (N/N', P) of the amount of data stored in the memory (1) is determined, after which the difference is compared with a reference value (...

A paint used as a corrosion-protective coating of products and structures of ferrous and non-ferrous metals adapted to operated in a temperature range of from minus 40 DEG C. to plus 550 DEG C. to 600 DEG C. The paint comprises (in weight %): direct-synthesis butanolized polyphenylsiloxane resin, 20-22; aluminum powder, 12-18; aerosil (pure silicon dioxide), 3-7; a copolymer of methylmethacryla...

The problems of buffer overflow and underflow encountered when employing actually variable or effectively variable bit-rate channels for communicating encoded video images are overcome by jointly controlling the number of bits employed to encode each video frame and the transmission bit-rate of the variable bit-rate channel as experienced by the encoder. The selection of the number of bits employe...

In a high efficiency encoding system according to the invention, a picture is divided in many three-dimensional blocks, or blocks consisting of n areas belonging to each of n frames continuous in terms of time. The movement of the picture is decided in each block to develop movement information. The picture element number of each block is sub-sampled into (1/m), and the phases are sequentially shi...

The electric precipitator has a housing (1) in which there is accommodated a system of discharge electrodes (ionising electrodes, ionic electrodes) (2) made from electrically conductive plastics and a system of precipitating electrodes (collecting electrodes, receiving electrodes) (5). The discharge electrodes (2) are constructed as module plates (13) which are joined to one another in a relativel...

An easy-open can, e.g. for liq. products, has a detachable disc (4) covering a hole (5) in the lid (3) of the can (1), which is detached to allow the can's contents to be poured. The disc can be made from the can lid, which. is shaped by dies prior to fitting to the can to produce the disc (4), which can be slightly curved in shape, and a stretched cylindrical edge round the hole, which can then b...

The underbody of a small or medium tank container has a pair of longitudinal fork stacker channels and a pair of transverse fork stacker channels extending perpendicular thereto. The transverse fork stacker channels (26) are defined by interruptions between profile rail parts (21, 22) of the longitudinal fork stacker channels. The profile rail parts (21) of the longitudinal fork stacker channels a...

Vengono descritti dei nuovi peptidi che rappresentano permutazioni della sequenza del mastoparano. I peptidi possono essere di interesse farmaceutico per contrastare patologie dovute ad alterazioni dell'interazione tra recettori di membrana e proteine G.; New peptides representing permutations of the mastoparan sequence are described. The peptides may be of pharmaceutical interest in counteracting...

Disclosed is a hipjoint socket for insertion into bone tissue. The hip-joint socket has an outer metal shell and an inner antifriction shell, the contact surface of the antifriction shell in the metal shell being conical in shape. The antifriction liner lies upon the conical contact surface without self-locking and the antifriction liner is fixed in the metal shell by a retaining ring. The antifri...
