Title: Vacuum dust collector for portable power drill -  has bag compartment shaped to cause kinking of dust bag and release of adherent dust layer
Inventor: GANTNER GEBHARD
IPC: E21B21/07
Filed: 1990-09-22
Abstract: Dust laden air is drawn through a collector ring (9) surrounding the tool bit (14) and into a paper or cloth bag (11) housed in a compartment (3) on the underside of the power drill. Just below the holding flange (13) of the bag are two shelves (6a,7a) which serve as corners about which the bag can kink and swing as a pendulum. On the front wall of the compartment is a corner (8a) causing a further kink as the bag swings forward. - Normal handling of the power drill in use causes the bag to swing against the corners (6a,7a,8a) and to kink, thus releasing the adherent layer of dust that develops on the inside of the bag.

Inventor: ABELE KARL-HEINZ DIPL ING
IPC: C21C1/02
Filed: 1991-08-28
Abstract: The invention relates to a process for treating molten pig iron for desulphurisation thereof in a vessel. The characteristic of the invention is that the treatment is carried out in three phases: In the initial phase, those solids are blown in which deoxidise the initial slag and increase its basicity, and effect a circulating motion of the melt or form a basic deoxidised covering slag. In the middle phase, a desulphurising agent is blown in for the main desulphurisation and, in the final phase, those solids are blown in which purify the melt and effect a final desulphurisation and affect the resulting desulphurisation slag in such a way that its content of iron granules is low. <IMAGE>

Title: Method and apparatus for fractionating measurement of aerosols
Inventor: BUERKHOLZ ARMIN DR
IPC: G01N21/85
Filed: 1993-04-22
Abstract: In the method for determining the particle size distribution in an aerosol-loaded gas stream, the gas stream (3) is fed through a separation-stage cascade (1) with stepped separation limits and the aerosol concentration is measured before and after each separation stage (2n). From the difference in the two measured values belonging to a separation stage (2n) the respectively deposited particle fraction for neighbouring separation limits is then determined. The method is, in particular, carried out such that the individual separation stages (2n) are connected up stepwise after one another in series, the measurement gas flowing through the separation stages (2n) already connected up, the aerosol concentration being in each case measured with the aid of a photometer after the last separation stage connected up. The corresponding apparatus consists of a separation-stage cascade (1), in which, after each separation stage (21...5), a connection line (41...5) which can be closed by a remote-controlled valve (61...5) leads to a collection tube (5). The aerosol concentration remaining in each case after a selected separation stage (2n) is measured with the aid of a continuous (through-flow) photometer (8) which is arranged downstream of the collection tube (5). A computer-supported evaluation and control unit actuates the valves (6n) in the connection lines (4n) and determines the particle size distribution and total concentration of the aerosol on the basis of the photometer signals measured after the separation stages (2n). <IMAGE>
