Title: Nuclear concrete pressure vessel with liner and cooling tubes - has tubes bent away from weld seams
Inventor: KRAEMER WIELAND
IPC: G21C15/12
Filed: 1975-06-03
Abstract: A concrete vessel, esp. for nuclear reactors, has an internal, pressure-tight liner made from welded steel sheets; cooling pipes on the outer face of this liner are welded to it and cross the weld seams of the liner. At the points where they cross the seams, these pipes are bent away from the liner, esp. in a U-shape, so that ultrasonic testing can be used for the seams of the liner, without disturbance from a cooling pipe in the immediate vicinity at the rear face of the liner. Ultrasonic testing can be used in the construction of the liner, without hindrance from the presence of the tubes adjacent to the seams. The method leads to a shortening of the total construction time.
Patent FR-2288793-A1 (FR)
Title: Vapour deposition in vacuum on substrates sensitive to heat - using electron beam device suitable for glass and plastic substrates
IPC: C23C14/30
Filed: 1975-06-10
Abstract: In a process for coating a substrate by vacuum evapn. and condensn., an electron beam is directed into a localised zone of a cooled holder carrying the material (I) being evaporated, and relative motion is applied between the beam and the holder so that (I) travels through the localised heating zone, the speed and beam-energy being correlated so virtually all (I) is evaporated; and the substrate is located in the path of the vapour. The electron beam is pref. stationary and (I) carried through the beam at a prescribed, uniform speed. (I) pref. consists of finely-divided particles fed onto the cooled holder. Used e.g. for the vapour deposition of materials onto substrates which are sensitive to heat, such as glass or plastic substrates.

Title: Wide objects transporter used on road vehicles - has frame which can be raised to inclined position
IPC: B60P3/00
Filed: 1976-02-18
Abstract: A wide object may be transported by road vehicle on a frame (B) which can be raised to the inclined position shown by hydraulic jacks (D). The frame (B) is connected by pivotal links (C) to a frame (A) fixed to the vehicle platform, and has rollers supported on a guide rail (3) on the frame (A).

Title: Fuel supply system for IC engine - has guide wall in liq. container with narrow apertures to distribute air and lengthen flow path
IPC: F02M25/00
Filed: 1976-07-30
Abstract: The feed mechanism distributes liq. in finely separated form and/or as vapour to an i.c. engine. The liq. is contained in a closed vessel having a distributor in the lower section. The distributor communicates with the external air and has apertures so that this air can reach the liq. in the container. A lead has one end connected to the upper side of the container and its other end connected to the suction pipe of the engine to supply the cylinders with fuel.

Patent FR-2365527-A1 (FR)
IPC: C02F3/12
Filed: 1977-09-23
Abstract: The organic constituents are degraded in a first activation tank (11) under aerobic growth conditions to the extent that both in this stage and in a second activation tank (21) under aerobic growth conditions, dominant formation of filamentous bacteria and bulking sludge is prevented. The pH of the waste water is initially adjusted so that the waste water has a pH of at least 6 on leaving this first biochemical stage (10). The waste water in the activation tank (11) is then aerated with air or oxygen until the organic compounds which favour the uncontrollable growth of filamentous bacteria are largely degraded. The concentration of the dissolved oxygen in the activation tank (11) must be kept at least high enough so that the concentration of the dissolved oxygen is still measurable in the overflow to the second biochemical stage (20). The activated sludge flocks forming in the first biochemical stage (10) are continuously separated off. In the activation tank (11) a biochemical unit per unit volume as high as possible is maintained.
