Title: Stable nano-sol of sparingly water soluble pharmaceutical - has external phase of gelatin selected to balance charge on drug particle to improve bioavailability
Inventor: WUNDERLICH JENS-CHRISTIAN
IPC: A61K9/51
Filed: 1991-12-05
Abstract: Prepn. of colloidally dispersed system of a pharmaceutical (I) sparingly soluble in water comprises (a) selecting a gelatin (deriv.) or collagen hydrolysate having an isoelectric point (IEP) such that at a particular pH it will neutralise the charge on particles of (I), (b) converting the selected cpd. to aq. soln. form, (c) adjusting the pH (in accordance with (IEP) such that nanoparticles of (I) formed will be stabilised by (almost) complete charge neutralisation, and (d) before or after step (c), (I) is dissolved in the aq sol or a soln. of (I) is combined with the aq. sol. (I) can be replaced by other sparingly soluble organic and/or inorganic cpds. (Ia). Also new are the nanosols themselves. They consist of (a) an inner phase of (I) or (Ia) of particle size 10-800 nm., having a negative or positive surface charge, (b) an external phase of gelatin (deriv.) or collagen hydrolysate with opposite charge and the charge balance between the 2 phases is almost isoionic. USE/ADVANTAGE - The systems are useful in tablets (with rapid or slow release), capsules, parenteral or bioadhesive formulations. The bioavailability of almost any (I) can be improved (by increasing the dissolution rate/without use of harmful additives, and the total (I) dose may be reduced. The process is simple, can use many different sorts of gelatin and by balancing the charges, Ostwald ripening (growth of the larger colloidal particles) is prevented, resulting in a stable, monodisperse system

Inventor: BENNIGSEN-MACKIEWICZ ANDREAS V
IPC: B65B69/00
Filed: 1992-06-04
Abstract: In order to achieve a metered emptying of containers for bulk materials, with the least possible generation of dust and avoiding complicated handling movements to be executed on the respective container, there is proposed a top-emptying device, in which a suck-off device, namely a suction pipe (10), is lowered into the container for bulk materials, the suction pipe (10) being guided so as to empty the container content respectively in layers. To guide the suction pipe (10) in layers, the latter is mounted rigidly on a quadrangular platform (7) which is itself fastened to an upper platform (5) via lifting devices (8) engaging at the four corner points. As a result of the synchronous actuation of all the lifting devices (8), a vertical lowering movement of the suction pipe (10) takes place, whereas, by a controlled varying activation of the lifting devices (8), the suction pipe (10) is set in pendulum movements corresponding to a movement pattern oriented to the cross-sectional shape of the container for bulk materials which is to be emptied. The emptying operation is continued cyclically until either it is stopped or the container is emptied completely. <IMAGE>

Abstract: A very simple and easy-to-use height adjustable apparatus for the shop sector, but also for the domestic sector, is achieved by a locking sleeve (2) which totally or partially surrounds an extending tube (4) which is displaceable relative to a fixed standing tube (5). In this arrangement, the upper and lower faces of the locking sleeve (2) are shaped in such a way that rotation about an axis (1) perpendicular to the longitudinal axis of the extending tube (4) is possible to such a degree that a wedge- or dome-shaped lug (3) on the inner side of the locking sleeve (2) can slide out of an opening (7) in the extending tube (4) and the locking sleeve (2) can then be displaced along the extending tube (4), the wedge- or dome-shaped lug (3) being integrally moulded on the lower inner side opposite the axis of rotation (1) or on the side of the axis of rotation (1) above the axis of rotation (1). When the extending tube (4) is lifted, the locking sleeve (2) rotates owing to its weight independently about the axis of rotation (1), and the wedge- or dome-shaped lug (3) slides out of the opening (7) in the extending tube (4). <IMAGE>
