Title: Floating pipeline for natural gas discharge - has pipes sliding freely in axial direction in distance pieces
Inventor: MANNAERTS KLAUS
IPC: B63B22/02
Filed: 1977-04-27
Abstract: The pipeline transports liquid or gaseous media, partic. refrigerated, between a fixed and a moving point, or two moving ones, one at least of which floats on the sea. It comprises two or more pipes each consisting of coaxial corrugated tubes with a heat insulating layer between, and running roughly parallel to one or more supporting ropes. Distance pieces on the ropes hold the pipeline in position and form a chain between the points. The pipes slide freely and axially inside the distance pieces on supporting bearings. Each distance piece can comprise two or more components of high tensile material, together forming a rectangular frame, and fixed solidly together after fitting onto the pipeline. Recesses in two opposite sides of the frame guide the pipes, while a shaft is mounted in the two other opposite sides, and carries the bearings.

Inventor: NOLTE DIETER
IPC: H01H47/00
Filed: 1977-06-18
Abstract: This switching device ensures that the high/low tone sequence of audible signal devices is inhibited when the optical switching means (B 1, B 2), for example a beacon light, does not light up, which can be detected by means of at least one monitoring lamp (K 1, K 2).

Title: Mandrel for expanding the ends of hot plastics tubes - to mould integral bushings; has heat-insulating enamel coating to avoid abrupt cooling of tube being pushed onto it
Inventor: SCHNALLINGER HELFRIED M ING
IPC: B29C57/02
Filed: 1977-07-26
Abstract: Mandrel for widening the ends of hot plastics pipes or tubes, esp. for shaping end bushings, is claimed. The mandrel is made of metal and has a thin coating of thermally insulating material e.g. an enamel, 0.2-1mm. thick. The enamel coating, being of heat-insulating material, reduce "temperature shock" to the thermoplastics material as is experienced when prior-art, relatively cold chromium-steel mandrels sprayed with lubricating oil, are used. As a result, the tube to be shaped can be much more easily pushed onto the mandrel. Also, contamination with the lubricant is avoided, and necessity of installing special heaters eliminated.

This is followed by removal of the HCl formed and concn. to the required (I) content under reduced pressure by (a) adding water (vapour) at under 70 degrees C until the residual water content is 15-30 wt. % or (b) concentration to a residual water content of 0.3 wt. % at a temp. below 170 degrees C, without addn. of water, followed by hydrolysis of the estolide fraction formed to (I) with water. Finally, the aq. (I) obtd. is diluted or conc. to the required concn. or, if 100% (I) is required, this is allowed to crystallise from the soln. Pure, salt-free (I) can be produced easily, without the formation of by-prods. which cause environmental pollution or other drawbacks.

Patent DE-2819703-A1 (DE)
Inventor: DERICHS JOSEF DR ING
IPC: B65H59/22
Filed: 1978-05-05
Abstract: In the operation of the bobbin creel with the pneumatically loadable yarn tension devices (5) the static loading pressure of the yarn tension devices is taken off, preferably per row of creels, from the pressure drop of a flowing pressure medium. A main line (18) through which a pneumatic pressure medium constantly flows is led along the creel. The pressure elements (6 to 14) of the yarn tension devices (5) are connected individually or in groups, preferably by row of creels, via stop lines (15, 16, 17), to the main line (18). The main line (18) can be subdivided by defined flow resistance elements (30, 31) into individual sections (32, 33, 34) of different static pressure. The yarns coming from the rear end of the creel are less intensively loaded than those coming from the front end of the creel. The result is a uniform tension of all yarns. The non-uniform loading relative to one another is maintained with change of the flow rate. <IMAGE>
