Patent DE-4021893-A1 (DE)
Title: Balanced pressure earth drilling rig - producing negligible emission of gaseous toxic pollutants
Inventor: GRUENANGER GERHART DR
IPC: G01N33/00
Filed: 1990-07-10
Abstract: In soil investigations to ascertain the nature of possibly toxic deposits, there is risk of emission of potentially dangerous vapours and aerosols (e.g. dioxins and furans) into the external environment. This invention provides a procedure and apparatus for sampling a bore hole (8) without allowing such release, involving sealing the bore hole outlet to a chamber pressurised with an inert gas. Prior to arrival of the drilling rig, a flanged well-head fitting (41/42) is driven into the ground at the proposed site. The mobile rig (1) is assembled around a combined road-going/rough-terrain vehicle (2) which is parked over the pre-sunk head fitting (42) and coupled to the fitting via a mating flange (32) on the floor of the rig pressure chamber. The drill tower (4) is arranged so that the drill string (45) passes through a mechanical seal (34) in the chamber ceiling, and enters the ground via the coupled head fitting (42). The pressurised chamber can be entered by operators, wearing suitable breathing apparatus, via air lock (51), but, drill changing, sampling, and even analytical procedures can all be performed by operators, outside of the chamber, working through glove boxes. The chamber is protected by explosion relief panels. Nitrogen gas is suitable for pressurising the chamber. USE/ADVANTAGE - Landfill waste disposal monitoring. Avoidance of contaminating drill operators and the external environment.

Title: Blockage correction for pneumatic suction transport system - applying suction level monitor and programmed air admittance along duct to clear blockage
Inventor: LUEBBEHUSEN PAUL
IPC: B65G53/24
Filed: 1991-03-26
Abstract: The pneumatic duct (3) transports granular material from a supply hopper (1) to a discharge point. A suction pump (6) at the discharge point provides the driving force. A manometer (16) measures the suction level at the discharge point and detects blockages i.e. by changes in suction level. A programmed control (15) operates a series of air admittance valves (11,12,13,14) to clear the blockage. The air is admitted in controlled amounts via groups of inlet jets, starting with groups near the discharge point and progressively moving to the inlet point. The material is normally moved at slow speeds, above the blockage speed. ADVANTAGE - Allows slow speed transport to minimise damage; self clearing control.

Title: Honeycomb exhaust gas assembly - for incorporation as catalyst substrate in motor vehicle exhaust catalyst
Inventor: USUI MASAYOSHI
IPC: F01N3/28
Filed: 1991-05-23
Abstract: In an exhaust catalyser core assembly, passages are formed by a metal strip and a corrugated strip made of another type of metal placed in contact, the two metals touching at regular intervals. The novelty is that the touching metal surfaces are roughened by between 1 and 1,000 scratches per mm on their surfaces to a depth of between 50 and 50 microns; that the honeycomb structure so formed may be rolled up together to form a multilayered spiral, may be stacked in alternate flat layers, or stacked in S-section; that the corrugated sheet metal is perforated throughout; that the stacked sheets of flat and corrugated metals are packed to fit within a metal casing of circular, oval or eliptic cross-section. USE/ADVANTAGE - The arrangement produces an assembly of great strength and stiffness; the abrasions at the points of contact facilitate deep penetration of soldering metal which remains physically sealed off from the catalytic material subsequently applied; the holes in the corrugated metal facilitate rapid heat distribution throughout the body and constant temperature gradient to provide constant reaction conditions; the arrangement is claimed to facilitate full catalytic effect due to constant gas flow and distribution.

Title: Folded wire bundle mfr. for detonation of explosive charge - transferring each completed turn towards end of winding pin, allowing withdrawal of individual loops from complete bundle
Inventor: GEBHARDT GOTTFRIED
IPC: H01R43/28
Filed: 1992-01-30
Abstract: The detonator wires (30a,30b) are wound around two pins (14a,14b) in a number of figure-of-eight loops.
