Title: Pharmaceuticals prepared from polycyclic bases and cation exchange resins
IPC: C07D223/26
Filed: 1968-08-09
Abstract: A pharmaceutical preparation (providing immediate and rapid release of the therapeutic agent for oral administration) comprises a suspension or dispersion, in a carrier liquid which is substantially free of ions or ionisable material, of a solid compound formed from imipramine, chlorimipramine, 10-keto-imipramine, desimipramine or opipramol base and a cation-exchange resin in the form of a methacrylate polymer containing carboxyl groups and having a degree of cross-linkage from 1 to 10%.

Title: Means and process for producing a false twist by friction
IPC: D02G1/02
Filed: 1969-01-04
Abstract: False twist is imparted to yarn by causing the yarn to contact a rotating annular friction surface 22, guides 28 and 29 ensuring that the yarn contacts the surface with out passing through the opening defined by the surface 22, The friction surface is preferably formed by a ring of reinforced elastomer which internally lines an end recess of a rotatable spindle 19. A V-shaped member having two arms 26, 27 with the yarn guides 28, 29 therein is either pivotally or slidably mounted so as to move into a position where both yarn guides are outside the opening. Previous to false-twisting the yarn may pass through an oven 15 of keyhole cross section for setting crimp, the oven having a safety system wherebyin case of current failure a cover 13 pivots and a direction changing section 14 also pivots to space the yarn away from the oven. The yarn may then pass through a metal tunnel 17 also of key hole cross-section for cooling purposes before passing to the false twist device 16.

Title: Stamp for sheet metal chain links - has cross formation links with opposite arms bent in loops encircling adjacent link
IPC: B21L11/10
Filed: 1977-03-17
Abstract: A strip of metal is fed with a step-wise motion under the punch which stamps out cross-shaped links.

Patent ES-457016-A1 (ES)
Title: Positive engagement clutch with soft engagement motion
IPC: F16D43/26
Filed: 1977-03-12
Abstract: To place a driven shaft in accurate angular alignment with respect to a continuously rotating driving shaft or, selectively, with respect to a fixed reference, the fixed reference is formed as a housing, the driving shaft has a disk with a cam track attached thereto, and the housing likewise has a disk with a cam track. The driven shaft has an engagement pin connected thereto, axially slidable and engageable, respectively, with the cam tracks of the driving shaft, or of the housing,. The cam tracks are arranged to carry along and gradually accelerate the pin coupled to the driven shaft until the pin locks at a predetermined position in the cam track to define the relative angular position of driving shaft and driven shaft upon different axial movement, the engagement pin is permitted to slide out of engagement with the cam track disk coupled to the driving shaft and engage a similar, and stationary cam track on the housing, again formed with a stop or rest position which again determines the angular relationship of the driven shaft with respect to the housing, and hence with respect to the reference. Axial sliding movement of the engagement pin is controlled by pneumatic pressure acting on spring-loaded pistons. The clutch is particularly useful in connection with printing machinery, especially rotary screen printing machinery, to provide for accurate alignment of intermittently operating printing stencil cylinders with respect to the instantaneous angular position of the machine drive shaft.

Title: Offshore pipe laying
IPC: F16L1/20
Filed: 1977-06-15
Abstract: The forward movement of a pipe-laying vessel when laying pipe offshore is controlled to maintain the position of the pipe as laid on the sea bed as close as possible to the desired track. The position of the touch down point on the sea bed of the pipeline suspended from the vessel is measured at periodic intervals by driving a survey vessel fitted with an echo location device along the already laid line. The measured position of a touch down point is compared with the desired track and any deviation is computed. Further movements of the pipe-laying vessel are adapted to minimize this deviation.
