Patent DE-4110940-A1 (DE)
Title: Arrangement to prevent cooling below dew point - in and downstream of smoke desulphurisation assembly
Inventor: STROEER KURT DIPL ING
IPC: B01D53/74
Filed: 1991-04-02
Abstract: In a smoke de-sulphurisation plant gases are abstracted through a pipe in the lower funnel-shaped regin of the reverse-flow reactor. The novelty is that hot gases are admixed gas to the smoke gases through a pipe arrangement; that the admixed may be introduced via a telescopic pipe, a circular gas pipe, a telescopic jet pipe and an elbow pipe, and the assembly held in position by a support; that one ring gas pipe is arranged around the abstraction pipe, and another circular gas pipe is arranged around the telescopic pipe. USE/ADVANTAGE - The arrangement prevents the gases within the downstream of a de-sulphurisation reactor cooling to below the dew point. Ash and sand are removed and collected upstream of the economiser. The pressure differential between the gas to be abstracted and the hot gases results in good mixing. The funnel-shaped lower reactor region is also heated, thus drying ash and enabling it to fall and flow under gravity. The flow of smoke is easily controlled. There is no redn. in the reactor de-sulpherisation vol.
Patent DE-4111686-A1 (DE)
Title: Contactless leak testing of workpieces using visible and IR light - applying gaseous and/or liq. test medium acting as detectable temp. contrast to surroundings at leakage points
Inventor: NOLTING THOMAS
IPC: G01M3/38
Filed: 1991-04-10
Abstract: A method of contactlessly testing workpiece for sealing involves subjecting the workpiece (10) to a gaseous and/or liquid test medium. The medium acts as a temp. contrast medium to the surroundings at a leakage point (40) and the workpiece is scanned (11-19) using infrared and visible light. After the workpiece has been scanned with infrared and visible light the corresp. signals are superimposed. The superimposed signals are pref. transferred as image data from an evaluation unit (22) to a screen (25) for image display. ADVANTAGE - Simple, practical optoelectronic detection.

Inventor: HABENSTEIN KLAUS DR
IPC: G01N9/00
Filed: 1991-05-17
Abstract: The invention relates to a process for measuring the ionic strength or the specific gravity of aqueous fluids and to a reagent for that purpose. The composition of the reagent is such that the colour change indicating the ionic strength is directly dependent essentially on the specific gravity of the fluid to be measured and not on a shift in pH.

Filed: 1991-08-14
Abstract: The downstream terminal section of a supply lumen (4) for rinsing fluid is designed as a nozzle (14) which directs a strong, sharp jet over a free section (I 30) into the inlet (16) of a discharge lumen (6). The jet of rinsing fluid generates a sucking effect by means of which it sucks material from the organ (8) being treated and discharges this material through the discharge lumen (6). In order to intensify the sucking effect of the jet of rinsing fluid the discharge lumen contains the following elements in succession, as seen from its inlet (16): a mixing pipe (18), a diffuser (20) and a discharge channel (22). <IMAGE>

Title: Jet engine assisting in glider take=off -  has front part of combustion chamber formed as backwardly open cover surface ofacute-angled hollow cone
Inventor: WEBER FRANZ-JOSEF
IPC: F02K7/10
Filed: 1991-08-23
Abstract: The front part (1) of the combustion chamber (2) is formed as a backwardly open cover surface of an acute-angled hollow cone (3), which in the region of the air inlet (4) has a specific number of backwardly directed apertures (5) which are inwardly screened. This means that after each fuel gas feed into the air inlet (4), an outwardly acting vacuum arises through the apertures (5). This makes it possible the penetration of fresh air into the front part (1) of the combustion chamber (2). As a result of this, after a further fuel injection and ignition, a further fuel insertion occurs. This process is repeatable until the requisite flying speed is reached. USE/ADVANTAGE - To assist in the take-off process of a glider.

Title: De=burring unit - has one fluid power cylinder that lowers cutter into stop controlled working position and pivots cutter outwards to remove burr
Inventor: GEYER JOHANN WOLFGANG
IPC: B23D79/02
Filed: 1991-09-30
Abstract: A de-burring unit has a cutter (4) pivoted (14) in a holder (6). The holder (6) can move between an upper position (6a') clear of the work and a lower working position determined by end stops (10a) on guide pillars (10). When the cutter has been lowered into position by the outward movement of fluid power cylinders (8), continued movement of the rod (7) causes a displacement (x) relative to the now stationary holder. The end of the rod then bears on a lever extension of the cutter causing it to pivot outwards and remove the burr on the workpiece. ADVANTAGE - Simple, cost-saving design.

Title: Audio and/or video recording system with special effects facility
Inventor: TEBBE GEROLD
IPC: A61M15/00
Filed: 1992-10-16
Abstract: A recording/playback system using audio and/or video passages has a facility to introduce other effects based upon recorded control signals.
