Title: Purification of gases and prodn. of hydrogen contg. salts - pref. by absorbing sulphur dioxide and producing sodium bisulphite
Inventor: KLINKE GREGOR DIPL ING
IPC: C01D5/14
Filed: 1975-01-16
Abstract: Purification of gaseous effluents (pref. SO2 cont. gases) combined with prodn. of alkali(ne earth)-hydrogen salts of polybasic acids in a multi-stage scrubbing appts. is improved in that the effluents are passed continuously and always in the same order through the scrubbing stages; the washing liquid flows in countercurrent to the gaseous effluents; and the washing liquid is periodically, partly or wholly, transferred between the scrubbing stages. Pref. a two-stage scrubbing appts. is used. NaHSO3 is pref. produced in a two-stage scrubber. In the first stage, the liquid is satd. with SO2 as far as possible to produce the acid salt at pH is approx. 4. In the second stage, the pH is maintained at about 10 by NaOH supplement to attain a high degree of the purification of the gaseous effluents. The Na2SO3-contg. soln. is partly transferred from the second stage to the first stage to be converted into NaHSO3 soln. There is no need to alter the direction of the gas flow. The process can be carried out continuously.

Title: Safety valve for hydraulically actuated devices - two chambers with axially aligned spring-loaded pistons
Inventor: KUPPLICH GERT
IPC: F15B13/02
Filed: 1975-05-05
Abstract: The safety valve is built into a block and outlets may be simultaneously subjected to a pressure from pressure relief valves. During active pressure, no outlet is supplied with pressure fluid from the control slide. The safety valve has two chambers, each with a piston (4, 8) and connected to a pressure fluid conduit (13, 14), associated with the corresponding outlet (A, B), and also to a discharge conduit (11). The pistons are axially aligned, and charged with the same spring load, which may be overcome by a hydraulic pressure, acting on both pistons. The pressure is smaller than that adjusted for the relief pressure valves. This allows the relative movement of the pistons, to free the passage for the outlet of pressure fluid from an outlet by a piston.

Title: Rigging system for sailing vessels - uses rhomboidal sails fixed at corners to pivot about vertical and mutually bracing masts
Inventor: DRECHSEL ARMIN
IPC: B63H9/06
Filed: 1975-12-17
Abstract: The rigging system for sailing vessels is applicable to any craft. The sails are rhomboidal and suspended corner-to-corner so that, to take up the required angle, they pivot about their vertical axes. To permit this, the masts are angled to the vertical and cross, bracing one another. In combination with their shrouds and stays and the hull they thus form a rigid space frame whose members, apart from the hull, are free from any significant bending stresses. Each sail embodies a central horizontal boom/yard which can be constructed so as to permit roll-reefing, using a drive from an appropriate point in the standing rigging. Extensive mechanisation/automation of other sail manipulations is also possible.
