Title: Tanker degassing equipment
IPC: B63B25/10
Filed: 1971-01-13
Abstract: Apparatus for extracting gas out of the spaces or tanks of oil tankers consists of one or more pipes extending along the tanker, control valves between the pipes and the spaces or tanks of the tanker for selectively allowing the stream of gas out of the spaces or tanks into the pipes, vertical tubes extending upwards from the pipes to above the deck level of the tanker, gas extractors connected with the upper ends of the tubes above deck level, and air diffusors placed in the deck for allowing a horizontal stream of air into the spaces or tanks in order to prevent the destruction of the layer formation of the gas in the spaces or tanks when suction is applied via the tubes and pipes on the lower part of the space.

Title: Bi metallic tubes - with specified properties of inner or outer layers
Inventor: JACKSON JOHN FABIAN BRINDLEY
IPC: B22D19/16
Filed: 1971-08-09
Abstract: Bimetallic or bialloy tubes composed of different layers with different mechanical props. can be centrifugally cast from a wide range of alloys, e.g. Cu, Cu alloys, Cr, Ni, Fe base alloys and alloys contg. Al + Si. Gas or slag protection is used to prevent the formation of oxide films on the solidifying surface of the primary cast layer before casting of the inner layer. This results in good jointing. An adjustable splash cap is also detailed which is used to compensate for the contraction on solidification of the primary layer and prevent material from the secondary layer reaching the outer surface of the tube. Tubes with high strength inner layers and corrosion resistant outer layers, etc., can be thus cast.

Title: Flue gas expansion chamber with staggered deflectors - forms a resistance for preventing dust loaded fumes entering the atmosphere directly
Inventor: HOELTER HEINZ
IPC: F27D17/00
Filed: 1973-08-16
Abstract: The flue gas expansion chamber is fitted on top of the outlet chimney from areas in which large quantities of hot flue gases are generated. Hot gases of this kind are generated by electric arc furnaces or by hot blown cupola furnaces. The flue gas ducting ensures that the furnaces are operated without disturbance. The expansion arrangement promotes the flow of hot gases into the dust extraction plant and if the quantities of hot gases are not high, then the atmospheric air is allowed to enter in the opposite direction. The expansion chamber has staggered baffles which are formed by equal angle profiles. These profiles are arranged so that they form inverted V-shaped baffles in a staggered pattern to the flow from below.

Title: Counteracting furnace wall subsidence - by pulling the wall back to a vertical position
IPC: F27D1/14
Filed: 1974-02-15
Abstract: Subsidence of the combustion chamber walls of industrial furnaces is overcome by opening up a stepped aperture in the wall, widening in the direction of subsidence, and cementing a ceramic wall anchor thereon, by casting, ramming or injection of refractory material, the wall anchor being supported by means of its claw and a tie bar with a tensioning device on the furnace structure, which is operated in the drive direction after hardening of the refractory material. Instead of having to largely dismantle and rebuild the inwardly sloping refractory wall, this can be pulled into an upright position at much reduced cost.

Title: Clamping ring pipe screw connection - uses sleeve nut with inner cone which pushes against ring with outer cone
Inventor: KUEPPER HANS W DR ING
IPC: F16L19/065
Filed: 1974-04-30
Abstract: The screw connection is for high pressure pipes connected to a housing. It uses a sleeve nut which has a conical chamfer at one end. The sleeve nut screws into a connecting hole in the housing. The conical end of the sleeve nut engages with the conical outside dia. of a split ring placed over the end of the pipe. The conical clamp ring is supported in the housing to which the pipe is connected by a ring which has a larger out side dia. than the split ring. The support ring in turn lies against a sealing ring with conical end face which sits against the conical end face of the hole which is drilled into the housing. The support ring lies against a step in the bore, so that the amount of compression of the sealing ring is limited.

Title: Multi cylinder IC vehicle engine - in which a valve timing device reduces noxious constituents in engine exhaust
Inventor: LANGE KARLHEINZ DIPL ING DR
IPC: F01L1/08
Filed: 1974-11-30
Abstract: The cylinders are divided into two groups, pref. evenly. The inlet and exhaust valve timing of one group is set so that both valves are open to the same extent at, or very near to, TDC, giving optimum engine running conditions and exhaust hydrocarbon composition. The other group is timed to bring the point where both valves have the same opening significantly before or after TDC, and this opening is made greater than the other. This will result in exhaust gases low in nitrous oxides; the two combined will have a relatively low level of noxious components overall.
