Title: Preserving the legibility of etched coding marks - on metal components after phosphating, by local copper plating before etching
Inventor: HUNZIKER RETO
IPC: C25D5/02
Filed: 1974-10-17
Abstract: Process for retaining the visibility of etched writing or coding marks on the surface of a metal prod. after that prod. has been subjected to a phosphate treatment. The novelty is that at first, a local coating is applied to the surface which will be etched, the coating having a colour which contrasts with the etched marks and which also repels the phosphate. The coating is pref. a layer or copper applied by a stamp using direct current, by a circular brush, or by a felt disc. Used for example, to mark numbers and assembly data on bevel gears after testing, but before phosphating to improve the sliding- or antifrictional- props. eliminates the lengthy process previously used in which covers were mechanically fixed over the etched marking prior to phosphating.

Title: Support bars of grillage with connectors - are locked on the connectors by deforming
Inventor: BORRING JAN MAKUBE
IPC: E04C2/42
Filed: 1974-11-15
Abstract: The grillage assembly is made from a number of parallel bars which have wedge shaped cross sections. The grillage bars are held by transverse rods which pass through holes in the grillage member. These bars are passed through all the members and the transverse bars are locked by denting the grillage bars from the underside. The deformation ensures positive locking. The deformation for locking purposes can be made by a chisel shaped tool which inparts the locking deformation action in one operation on the assembled grille underside. the grille members can be joined also by flat strips which are placed in the slots in the ends of the grillage members. This arrangement considerably simplifies the production techniques.

Title: Automatic seaming and hemming on a blind stitching machine - in which straight edge guide permits sewing of all seams
Inventor: AHNERT PETER
IPC: D05B35/10
Filed: 1975-01-25
Abstract: A device for automatically seaming and/or hemming on a blind stitch sewing machine, is assembled on a worktable so that the sewing plate is flush with teh smooth working surface. A guide strip is positioned in front of, and offset towards, the machine housing side, relatively to the sewing point. The guide strip is located in front of the presser foot and inclined at an acute angle to the sewing direction, on a line running to a point spaced from the point where the needle enters the fabric, equal to the distance between the row of stitches and the edge of the goods, on the machine side of the needle. On the garment section side of the guide strip, a holding down strip is placed so as to allow an unrestricted feed of the garment sections whilst preventing creasing and folding in the edge zone. Without altering the guide bar, garment sections can be automatically seamed along straight or curved edges of differing radii.

Title: Mixer for particulate solids in silo - having aeration to silo controlled by level of solids in pneumatic mixer
Inventor: HEIDEBROEK REINHARD
IPC: B01F33/40
Filed: 1975-03-01
Abstract: Process for controlling the air necessary to loosen solids in a mixing system for particulate solids in a silo consists of a central mixing chamber to which air is admitted, the solids level in which is used as a control parameter for the air flow to the main silo. For this purpose a measuring probe, of either capacitance or radioactive type is used, the signal from which is passed via transmitter and controller to a control mechanism on the air flow to the side. The raises or reduces the airflow depending on the solids level in the mixing chamber. For use on silos employing central mixing chambers. If due to inadequate aeration, not enough material flowdown, no mixing occurs and the output is insufficient. On the other hand, overaerationleads to choking of the chamber and poor mixing. The system described ensures adequate aeration even with variations in the properties of the solids being handled.

Title: Universal joint for angular torque transmission - has cross head with rollers to reduce friction of axial movement
Inventor: RINDLISBACHER HEINZ
IPC: F16D3/205
Filed: 1975-07-09
Abstract: A universal joint consists of a cylindrical component (8) which is the driven part and a spherical body (2) with a shaft extension (3) coupled to the drive. Perpendicular to the drive shaft (3), the sphere (2) has two opposite spigots (4) which carry a roller (5) each. The sphere (2) with the rollers (5) are located in a round hole and two opposite axial recesses (7) inside body (8). When transmitting a torque at an angle between input and output shaft, axial movement between the two component takes place. This movement causes the roller (5) to rotate, thus the friction losses are reduced to a minimum.

Title: Foil-length -covered free-standing arched hangar structure - has foil ends connected to base-anchored beam, sagging under stretched foil
Inventor: FRANKE RUEDIGER DR ING
IPC: E04H15/32
Filed: 1975-04-04
Abstract: The arched free-standing hangar structure incorporates a support of parallel trusses with lengths of foil sheet fixed on them. The bottom ends of these lengths are stretched by means of a clamping medium connected to the base, in such a way that the centre is more powerfully drawn upwards than the edges. The bottom end of the length of foil (F) is connected across its whole width, with a bar-shaped beam (3), anchored to the base (6). The degree of rigidity of this is such that it is elastically sag-deflected to a readily visible extent by the length of foil which is set under stretching tension. The bottom end of the foil may be fitted with a loop (1) which can accommodate the beam and be curved to match the curvature of the tension-subjected beam. A more evenly distributed foil stretching is attained, over its whole width.
