Title: Double pipe heat exchanger for cracked gases - having direct pipe connections to cracking tubes and distributor for coolant
Inventor: HERRMANN HELMUT DIPL ING
IPC: C07C4/04
Filed: 1975-11-14
Abstract: Heat exchanger for cooling cracked gases has an extended block of double pipe elements with outer pipes for the coolant and the inner pipes for the cracked gases. The gas distribution chamber consists of a flanged trough shaped header which runs the whole length of the cooler. It has a series of gas inlet branches along its length. The inlet header is lined with a refractory insulating material. Both inlet and outlet headers are of the same form. The coolant is distributed and collected by oval tubes running along the inner side of the gas headers. The feed is via tubes which drop into the distributor. The water/stream outlet mixture is collected by rising tubes. Usee with cracking plant for producing olefins and petrochemicals from hydrocarbon feedstocks. The problem esp. when using heavy feedstocks is that there is a low residence time in the furnace and it is essential that the reaction is quenched rapidly. The cooler allows direct connection from the narrow bore furnace tubes to the distribution header. The flanged construction makes maintenance straightforward.

Inventor: BARZANTNY JOACHIM
IPC: G01V3/15
Filed: 1977-04-26
Abstract: Appts. for detecting and surveying reinforcement in concrete comprises a metal detector. As the sensing head of the detector is moved in a first direction a first voltage is varied, while as it moves in a second direction perpendicular to the first a second voltage is varied; the first voltage is supplied to the first input of an X-Y plotter, while the second voltage is added to the output voltage of the detector and is supplied to the second input of the plotter.

Title: Shaping thermoplastic tube into smooth socket with collar - using equipment which provides a radial space during outwards expansion of the wall
Inventor: KAELCKE HORST
IPC: B29C57/06
Filed: 1977-07-19
Abstract: The parent patent claims the formation, in stages, of the end of a thermoplastic tube into a socket with an outer collar. The end is first heated, expanded on a mandrel with corresp. redn. in wall thickness, and then compressed to increase its thickness again so that it has at the collar at least the same compression strength as elsewhere. The collar area is then pressed out into a space, and the tube wall by the collar is increased in thickness from the outer or inner side. The improvement comprises increasing the wall thickness under pressure whilst creating further outer space for it along the whole length of the collar. The improved system prevents formation of creases even with thick tubing.
