Title: Anti-corrosion aluminised coating - for ferrous metals with brazed joints
Inventor: SPEIRS KENNETH K
IPC: F01D25/00
Filed: 1974-10-15
Abstract: Prodn. of a thermally diffused corrosion protecting aluminised layer on stainless steel components with brazed joints where the braze material is a non-ferrous alloy at m.pt. 607-1052 degrees C and esp. an alloy based on Cu, Ag, or Au, with m.pt. 635-1010 degrees C, involves protecting the braze from excessive Al penetration by selectively plating it with a 0.005 mm layer of Ni. Selective plating is achieved by chemically depositing Hg on the braze, immersing in aq. HNO3 or CrO3 to remove Hg and passivate the steel, followed by electroless Ni plating which deposits only on the braze. After aluminizing, corrosion protection is further improved with one or more silicate coatings opt. followed by chromate/phosphate treatment. Used for mfg. components, e.g. for turbines, which draw in air and operate in marine conditions. Weakening of brazed joints by excessive penetration of Al is prevented.

Title: Combustion engine with carburettor - has vacuum evaporator to purify and pre-heat fuel mixture between carburettor and cylinder inlet
Inventor: SCHWEPPE ERNST
IPC: F02M31/093
Filed: 1975-03-10
Abstract: The vacuum evaporator is arranged downstream of the carburettor, such that, whilst the engine is running under partial load or idling, the mixture from the carburettor is diverted to the evaporator where it is pre-heated before being admitted to the cylinder. The vacuum is preferably that created by the inlet stroke of the pistons whilst pre-heating is effected by heat exchange with the exhaust gases. Purification preferably takes place by guiding the flow of carburettor mixture such that heavy components are separated by centrifugal action or reversal of flow. Diversion of flow downstream of the carburettor may be achieved by a diverter valve which is piston-operated by the vacuum at that point.

Title: Reed switch contacts - produced by uniform annealing and local high temp. annealing, flat squeezing and cutting
Inventor: GROBE WOLFGANG DIPL ING
IPC: H01H11/00
Filed: 1975-06-16
Abstract: Reed contact cores for magnetically controlled reed switches consist of a magnetically hard material. They are mfd. by annealing the wire in a homogeneous temp. field at a predetermined temp. uniformly over its whole length. It is then briefly heated at specified spots at a much higher temp. inhomogenously, and then squeezed flat at these spots. Finally the reeds are cut off to size. This method is ideally suited for the mass prodn. of contact reeds which have to be annealed in sections. Specifically, the wire of magnetically hard material is annealed over its full length at 500-600 degrees C for 1/2 to 1 hr. to produce a constant coercitivty. The spots which will be beyond the final magnetising coils are soft annealed at 800-1000 degrees C for 3-30 sec. so that they can be easily squeezed flat.

Title: Cyano-acetamide derivs. prepn. - by reacting halo-acetamide derivs. with alkali cyanide in the presence of water as solvent
Inventor: QUADBECK-SEEGER HANS-JUERGEN D
IPC: C07D213/85
Filed: 1975-08-28
Abstract: The derivs. are of formula (I): NC-CH2-CO-NR1R2 (where R1 and R2 are H, (cyclo)aliphatic residue, or NR1R2 is a heterocyclic ring). They are prepd. by reacting halo-acetamide derivs. of formula (II): X-CH2-CO-NR1R2 (where X is Cl or B) with an alkali cyanide in the presence of water. (I) are useful as starting materials for dyes, adjuvants, pharmaceuticals, vitamin B6, plant-protection agents, and amino acids. Use of water as solvent improves the simplicity and economy of the process, and enables (I) to be obtd. in better yields and purity. By-prods. are not formed to a significant extent. The process is esp. used for large-scale prodn. because the prepn. of (II) can be combined with conversion into (I) in a 2-stage but 1-pot process. In an example, N,N-diethyl-cyanoacetamide is prepd. in 88.5% yield by treating N,N-diethylchloroacetamide (149.5 pts.) in MeOH (500 pts.) and water (500 pts.) with aq. 30% NaCn soln. (163 pts.) and stirring for 7 hrs. at 60-70 degrees C.

Title: Joining and relaying underwater pipelines - using buoyancy tanks to reduce the lifting load
Inventor: ELLS JOHN WILLIAM
IPC: F16L1/26
Filed: 1975-09-24
Abstract: In the joining together of the ends of two pipelines to form a continuous pipeline in an off-shore location, in which initially at least one of the pipelines is submerged, by(a) lifting one or more submerged pipeline ends above the surface and ensuring that the pipelines are not filled with water over the length to be raised and (b) joining the ends of the pipelines together while they are above the water surface, to form a continuous length which is then lowered to the bottom with lateral displacement to take up the excess length of pipe, the improvement whereby a float and more especially a series of buoyancy tanks, is used to assist in the raising and lowering operations. The use of the buoyancy tanks avoids the need for very heavy lifting equipment, since the pipeline may without such floats have a negative buoyancy of 45-225 kg/m, and partic. 75-150kg/m.
