Title: Process for esterification of tertiary terpenic alcohols
IPC: C07C69/00
Filed: 1970-05-26
Abstract: Esters of saturated or unsaturated aliphatic acids and tertiary aliphatic alcohols containing a vinyl group with the ethylenic double bond between the [alpha]-# positions to the tertiary carbon atom, are prepared by heating the alcohol with a molor excess of saturated or unsaturated aliphatic acid anhydride (C 4-12 ) at a temperature and pressure to distil the acid formed and excess anhydride from the mixture, and separating the ester from the remaining alcohol by fractional distillation. The alcohol may be where R represents a saturated or unsaturated aliphatic radical (1-10 C), R 1 and R 2 represent a saturated or unsaturated aliphatic radical (1-8 C) and R 2 may be hydrogen, a R 1 and R 2 may together form a tri- or tetra-methylene ring, e.g. linalol.

Patent ES-453905-A1 (ES)
Title: Device for use in emergency locking mechanism for webbing-type safety belts
IPC: B60R22/405
Filed: 1976-12-03
Abstract: A variety of belt locking mechanisms are disclosed, each utilizing a first mechanism responsive to sudden tensioning in the belt to lock it against further withdrawal, and a second involving a pendulum mechanism responsive to sudden changes in vehicle speed to lock the belt. Each belt tensioning device includes a reciprocable pin or shaft reponsive to increased belt tension to shift in a direction in which it causes a locking lever to engage lockingly with the teeth on a cogwheel which rotates with the spindle on which the belt is wound. The locking lever may be held against the resistance of a spring in its released position by a pendulum-type mechanism which moves in response to sudden changes in vehicle speed to release and allow the latch to pivot to its locking position. Alternatively, the motion-responsive pendulum or mechanism, or a similar mechanism, will operate a second cogwheel frictionally coupled to the first-mentioned cogwheel, to increase belt tension and lock the belt through the belt-tensioning device proper.

Patent ES-8301357-A1 (ES)
Title: A cooling tower and a method for the stabilisation of the boundary flow in the cooling tower
IPC: F28F25/12
Filed: 1981-06-25
Abstract: A cooling tower has a wall (1) defining a cooling air flow passage which reduces in cross-section along the direction of air flow towards a neck region (2) and then widens again. A body (3) is mounted on the wall in the neck region (2) to direct air from a central portion of the passage to a radially outer portion of the passage. In this way energy rich air from a region in the passage substantially uneffected by wall friction is injected into the energy-poor air in the boundary layer in the vicinity of the neck region. This helps to avoid boundary layer separation and thereby maintain the cooling efficiency of the tower which would otherwise be reduced.
