Title: Safety binding for skis - releases boot at tip and heel, upwards and sidewards
Inventor: MUELLER FRITZ DIPL ING
IPC: A63C9/00
Filed: 1973-06-22
Abstract: The binding has a release mechanism, consisting of a rigid arm, held by pins, which can move upwards, but is held rigidly sideways. A double linkage rod with transverse head and curved sections is pivoted on the double arm. A stationary axis is axially guided in the double arm, and the curved sections engage in it. A double tension spring is located between the axis, in the front part of an extended double arm. The jaws support themselves, via a guide roller a slide surface of low friction, on a sloping guide surface, so that they move sidewards in a horizontal direction. In normal position, and during upward movement, the jaws are pressed against contact surfaces on an extended angular bearing block, and the extended double arm. The double arm carries a pin, engaging in a recess in the block, and guided by it during upward movement. The jaws carry exchangeable front guide sections.

Title: I.C. engine cylinder liner expansion compensator - is ring with higher expansion rate than liner
Inventor: LEITGEB WALTER DIPL ING
IPC: F02F1/16
Filed: 1973-06-26
Abstract: Cylinder liner, especially for water cooled I.C. engines is provided with a ring, tensioned between the cylinder block abutment face, and the liner lip. A surrounding expansion gas, formed by the insertion of a steel insert during the moulding process, begins at the abutment face and extends outwards at a slant in a mushroom shape to avoid cracking. The ring cross section has a machined out area facing the cylinder head which gives the ring a certain elasticity in order to expand and at the same time allow the cooling medium to reach the liner lip. The ring is manufactured from a metal having a considerably higher expansion rate than that of the liner.

Title: Injection-moulding barrel with sliding screw - has an inlet groove intended to ensure trouble-free, forced, feed of the moulding cpd
Inventor: GUETTLER JO
IPC: B29C45/62
Filed: 1974-07-06
Abstract: An injection-moulding cylinder with sliding screw adapted for the injection-moulding of all types of plastics, has an inlet groove intended to improve feed conditions in such a way that trouble-free, forced, conveying of moulding cpd. is ensured, irrespective of screw dia. and type of plastics. The groove enables the pitch and depth of thread of the screw to be proportioned in such a way that optimal processing parameters are achieved. Owing to the screw dia. being rel. great the injection press. can be considerably increased. This, in turn, leads to improvement of the quality of the resulting moulding esp. in the case of precision components.

Title: Metal cpds. removal from crude or heavy oils - by addn. of fine coal or coke and subsequent sepn.
Inventor: KOENIG GERHARD DIPL ING DR
IPC: C10G25/09
Filed: 1974-07-16
Abstract: Metal cpds. are removed from crude oils or from heavy oils obtained from these, by mixing with finely-divided carbon, at a temp. sufficient for good mixing, and then removing the carbon enriched with metal cpds. Ash content is reduced to less than one-third of the original valve, by a simple economic process. Deactivation of catalysts in subsequent processing, e.g. hydrocracking into distillate fractions, is prevented.

Title: Bisphenol-A polycarbonate prepn. - by melt transesterification of molten bisphenol and diphenyl carbonate
Inventor: WULFF CLAUS DR
IPC: C08G64/30
Filed: 1974-08-17
Abstract: An aromatic polycarbonate of high mol.wt. is prepd. from diphenyl carbonate and Bisphenol A according to the known melt transesterification process, but using raw matls., which as pure substances have never passed through the solid phase, in proportions by wt. of between 30:70 and 70:30 (pref. 45:55 and 55:45). Previous process using crystalline diphenyl carbonate and Bisphenol A led to difficulties in excluding O2 and consequently poor coloured prodt. Use of molten, never crystallised raw matls. makes O2 exclusion much easier giving prodt. of pale colour.

Title: Pressure seal formed inside gas filled cable - by multistage foam injection through sheath without stripping sheath
Inventor: HOCKE KURT ING GRAD
IPC: H02G15/117
Filed: 1974-08-26
Abstract: A method of making a press-tight plug seal in a gas-filled electric cable, esp. a polyethylene-insulated or paper-insulated telecommunications cable, consists of introducing a liq. sealing matl. into the interior of the cable sheath through holes in the sheath with inlet devices connected to these holes, so that the liq. is introduced directly into the cable core, where it foams to produce a foam plastic seal. Pref. where the cable core is wrapped with a sealing matl. three holes are formed in three corresp. approx. equal lengths of the cable defined by four temporary constrictions the two outer inlet devices are first used to introduce the foam into the respective annular spaces between the calbe sheath and the core wrapping in these two outer chambers then these two inlets are plugged, the two middle constrictions are removed and the sealing matl. is injected through the central inlet through both the cable sheath and also the core wrapping so that in the central region the core wrapping is pressed outwards slightly against the cable sheath. while in the outer chambers it fills up inside the core wrapping; the two outermost constrictions are then removed. Pref. the depth of each constriction is equal to the thickness of the cable sheath. Pref. foam is polyurethane.
