Abstract: The invention relates to injectable media for ultrasonic echography in the form of microbubbles or microballoons comprising at least two biocompatible substances A and B (gaseous at the body temperature) forming a mixture which when in suspension with usual surfactants, additives and stabilisers provides useful ultrasound contrast agents. At least one of the components (B) in the mixture is a gas whose molecular weight is greater than 80 daltons and whose solubility in water is below 0.0283 ml per ml of water at standard conditions. The presence of the first component (B) in the contrast medium may vary between 0.5 and 41 volume percent. The other component (A) of the ultrasound contrast media is a gas or a mixture of gases whose molecular weight is below 80 daltons. The second component is present in a proportion of between 59-99.5% by vol., and is preferably chosen from oxygen, air, nitrogen, carbon dioxide or mixtures thereof. Gas mixtures described are found to be very effective as ultrasound contrast media. The invention also comprises a method of making the ultrasound contrast medium, the contrast agent and the ultrasound agent kit.

Patent AT-397482-B (AT)
Title: Mount for gang saws
IPC: B27B3/30
Filed: 1988-04-26
Granted: 1994-04-25
Abstract: With the configuration according to the invention, tilting of the gauge faces 5 of the sawing buckles 3 and, if applicable, of the distance gauges 6 is avoided, so that the finished gauge accuracy has a retaining effect by flush bearing contact of the gauge faces 5 in the mount, whereby equal board thickness' and a higher yield are achieved. The invention also ensures the greatest possible free saw blade length and the greatest possible cut-in height. This takes place by the two length regions 7 + 8 of the sawing buckle 3 being configured in such a way as to be pivotally movable obliquely with respect to the plane of this saw blade at the level outside the saw blade length 9 and in the direction of the row 3a of the sawing buckles 3 by means of a joint represented as a collared rivet 10, bolt or screw, which has the collar midway along its length, in a way known per se, but joint- less and with a shorter free saw blade length. <IMAGE>

Title: Piano key mechanism
IPC: G10C3/16
Filed: 1987-10-09
Granted: 1989-06-26
Abstract: In a piano key mechanism, for upright pianos or similar pianos with essentially upright strings 1, a magnet unit 39 is provided for each string damper 3, for providing the damping force, which magnet unit has a stationary magnet part 40 and a movable magnet part 38, which interacts with the stationary part via a gap 46 and is connected to the string damper 39, and also a movable magnet screen 41. The magnet screen 41 is connected to the associated key 4 and, when the key 4 is operated, lies in the gap 46 between the two magnet parts 38, 40, by virtue of which the magnetically generated damping force is suspended. When the key 4 is not operated, the screen 41 lies outside the gap 46 between the two magnet parts, by virtue of which these attract one another and a damping force can be applied to the string 1. Damping which is to a great extent similar to a grand piano in sound pattern is thus possible in a simple manner. <IMAGE>

Abstract: A process for the recovery of copper and zinc values from copper and zinc containing sulphidic ore includes subjecting ground ore to a flotation operation. An initial copper concentrate is floated in a first flotation step, and the initial copper concentrate is fed to a second flotation step to float a relatively zinc free copper concentrate. Remaining ore from the first flotation step is fed to a third flotation step to float an initial zinc concentrate, and remaining ore from the third flotation step is fed to a fourth flotation step to float a copper and zinc containing material. An intermediate concentrate containing from about 5 to about 25% copper and from about 2 to about 25% zinc, with a total of at least about 12% copper and zinc, is produced by selecting at least the remaining ore from the second flotation step, and a zinc concentrate containing at least about 20% zinc is produced by at least selecting a portion of the initial zinc concentrate.
