Title: Apparatus for the elimination of concrements
Inventor: SCHUBERT WERNER DR MED
IPC: A61B17/00
Filed: 1984-11-09
Granted: 1986-06-19
Abstract: The performance of the Dormia basket having a Teflon hose can be improved for removal of calculi. For this purpose, fluid is to be used via the Teflon hose for blowing on to the front part of the Dormia basket, and this is achieved by an umbrella-like sail present there. This improves unfolding of the Dormia basket in the body duct containing the calculus, and the Dormia basket which initially is still elongate can overcome obstacles better and slide forward past the calculus while at the same time the duct wall is pushed away by the fluid to which a lubricant may be added. Even before unfolding of the Dormia basket inside the Teflon hose, smaller nozzles can be used to improve sliding and forward movement. Crushing of a calculus can be achieved with simple means by a metered, axially directed explosive surge in the Dormia basket in that the calculus is pulled, from proximally to a small, lengthwise explosion chamber having a nozzle at the front by additional pulling wires which engage at the front pole of the Dormia basket. <IMAGE>

Title: Leaning ladder
Inventor: NENTWIG JOSEF
IPC: E06C7/42
Filed: 1985-05-15
Granted: 1986-10-30
Abstract: Ladders are important working devices in industry and craft as well as in the private field. Their "technical development" is placed in question by the high number of in part serious accidents during daily use. The details described in 6 points make the light-metal leaning ladder safer in its use. The slip coating with rubber tube has a positive effect to the sides and also perpendicularly to the ladders. The hard rubber round feet are antislip and are suitable for any pitch. The support feet are trapezoidal sheets, onto which T-profiles are welded at an obtuse angle of approximately 100 DEG . The webs of the T-profiles are covered with rubber tube and glued like the ladder uprights and ladder rungs. The coating with rubber tube has the effect that delicate floors cannot be damaged or the T-irons cannot penetrate the earth in the case of soft ground. The ladder leaning surfaces reduce the lateral slip and damage to surfaces.

Patent DE-4230098-C1 (DE)
IPC: C08G18/76
Filed: 1992-09-09
Granted: 1993-06-03
Abstract: The method provides for continuous separation of residues from raw m-diaminotoluene mixtures (m-TDA; 2,4/2,6-diaminotoluene mixture) in the manufacture of residue-free 2,4/2,6-diaminotoluene mixtures (m-TDA). The use of the residue-free m-TDA mixtures is also disclosed. The residue-free m-toluylenediamine is prepared by nitration of toluene, hydrogenation of nitro compounds, separation of the water and solvent by distillation, and removal of the ortho-isomers from the toluylenediamine mixture by distillation. A sufficient quantity of 2,4- and 2,6-toluylenediamine (m-toluylenediamine, m-TDA) is distilled off from the residual product to leave tails having a 30 to 70 wt % residue concentration, an appropriate quantity of said tails being mixed with an adjuvant, inert to toluylenediamine and having a boiling point of over 290  DEG C, to give a residue concentration of 28 to 50 wt %. The tails mixed with the adjuvant are subjected to a further single or multiple stage distillation until a 2,4- and 2,6-toluylenediamine residue concentration of 1 to 5 wt % is reached, and the remaining residual tails, still liquid at low temperatures, are sluiced out.

Abstract: The circuit has a synchronisation separation stage for extracting a line synchronisation component from the video signal and a vertical separation stage for supplying image synchronised vertical pulses, with a synchronisation device providing a line synchronised clock signal, the video signal processing controlled in dependence on the video signal source identified via the latter clock signal and the vertical pulses. A counter and memory stage (30) provides a signal identifying the time duration for which the video signal line synchronisation component and the vertical pulses are not synchronised, fed to a further stage (31) providing a signal with two different values dependant on whether the received signal is within, or outside, a defined range. This signal is fed through a low-pass filter to provide the control signal for the video signal processing. ADVANTAGE - Uses video signal itself to identify video signal source.
