Title: Post element, capable of being clamped to a road protective barrier, for information signs
Inventor: DICKE WERNER
IPC: E01F9/669
Filed: 1982-01-14
Abstract: The post element consists of a flat-steel member bent approximately at right angles. An information sign e.g. a road sign, is attached at the top of one leg, which is vertical after attachment. Fastened to the end of the horizontal leg of the flat-steel member is a bracket which is bent in the shape of a U and can be mounted on the upper edge of the road protective barrier, which is directed away from the road. The bracket is firmly clamped with the aid of two clamping screws. As a result of the pressure of the two clamping screws (16), protuberances or warts are formed on the edge of the protective barrier, which can be accommodated by blind holes (14a) in the opposite leg of the clamping bracket. <IMAGE>
Patent DE-3205491-A1 (DE)
Title: Gathered blind
Inventor: BAUMANN WILLI
IPC: E06B9/32
Filed: 1982-02-16
Abstract: The gathered blind, the slats (2) of which are pivotable, has a supporting member (3) which engages on the slats between the slat ends and which is fastened to a turning roller (7) arranged above the slats (2) in the pull-up direction. Pivoting limitations for the slats (2) allow an open and a closed slat position and a middle position. The turning roller (7) can be coupled to the pull-up shaft (30) via two helical springs (63, 67) clamped on this shaft (30). The springs (63, 67) are connected to the turning roller (7) at one point in a manner free of play and fixed in terms of rotation, in order to ensure that the slats (2) remain in their middle position. This gathered blind makes it possible to assume not only the horizontal and vertical positions of the slats (2), but also a predetermined adjustable middle position, although no undesired backward pivoting of the slats (2) can occur. At the same time, in this gathered blind, the control of the slat position is not carried out by a release fastened to the pull element (38), but the release (44, 45) forms an actual part of the pull-up device of the blind. It is directly integrated as such in this pull-up device. <IMAGE>

Patent DE-3232497-A1 (DE)
Title: Device for obtaining mechanical energy from heat energy
Inventor: MORITZ RICHARD
IPC: F03G7/06
Filed: 1982-09-01
Abstract: The device is used to obtain mechanical energy from heat energy, with a low heat potential. This is achieved by using the expansion of gases when heated. The device comprises a cylinder (1), around which hot and cold liquid flow alternately. Due to the reduction in volume when the colder liquid flows around the cylinder, the piston (2) at the outlet of the cylinder (1) is moved towards the cylinder (1) and draws in hydraulic fluid from the reservoir (5) via the nonreturn valve (3) (intake stroke). If warmer liquid then flows around the cylinder (1), the piston (2) moves away from the cylinder (1) due to the volume expansion, and presses the hydraulic fluid through the nonreturn valve (3) into the hydraulic motor (6) (pressure stroke). The flow of the liquids through the vessel (4) in which the cylinder (1) is situated is controlled via electrically controlled valves (8, 9, 10, 12, 13). There are temperature sensors (7) at the inlets and in the cylinder for recording the temperatures. The electric control compares the temperatures of the inlet and the cylinder. If the temperature difference has fallen to the desired value, the valves are controlled in such a way that the vessel is emptied. If the flow-monitoring device (11) indicates that the vessel is empty, the next cycle begins. <IMAGE>

Patent DE-3300989-A1 (DE)
Title: Elimination of the orange-peel effect in arc-sprayed coatings
Inventor: OTT WALTER H R DIPL ING
IPC: C23C4/131
Filed: 1983-01-14
Abstract: Like flame spraying, arc-spraying is a thermokinetic process for applying alloyed and unalloyed metals, and also pseudoalloys. The continuously fed spraying material may be used in the form of wire, insulated metal sheathed wire or flattened wire employing a bifilar system. The spraying material (spraying wire) reaches its liquidus at the short-circuit point of the arc. A spraying apparatus is required for the continuous process. As soon as the spraying wire fed in has reached its liquidus, it is atomised by atomising air or inert gas and the spraying particles produced acquire their direction of flight and kinetic energy, in addition to the internal energy already acquired. As a result of the atomisation, the particles acquire an irregular shape and are deformed into spheroids of varying size during their flight path while they are still in the molten state. Large spraying particles (drops) result in the orange-peel effect. This is due to the temperature difference at the positive and negative electrodes. Analogously, the spraying wire has to be fused more slowly at the low-temperature electrode than at the electrode with the higher temperature. According to the invention, this is also the basis of the claim. As a result of the kinetic and internal energy, the spheroids are deformed on striking a substrate so as to match the surface and form the deposit.

Title: Process for flue gas desulphurisation having a gas distributor in the cooling tower without a bottom surface
Inventor: HOELTER HEINZ DIPL ING
IPC: F28C1/00
Filed: 1983-05-19
Abstract: The invention relates to a process for flue gas desulphurisation, preferably downstream of old power stations having low cooling towers. According to the main application P 3314678.0, the scrubbed flue gas from the flue gas desulphurisation plant is passed via a large surface area distributor into the vicinity of the bottom of the cooling tower. In order to achieve design distribution in the vicinity of the bottom to be on as large a surface area as possible, according to the invention it is proposed to design the gas feed (1) in the shape of a ring, that is to arrange it open towards the water flume (9) and to immerse and support this in the water flume so that the trickling water from the cooling tower (3) flows through the ring arrangement downward into the water flume and in the course of this at the same time washes out the entrained droplets from the scrubbed dirty gas. The boundary surfaces of the distributor (4) are perforated. <IMAGE>
