Title: Decorative faced wood panels - hot pressed immediately after falling onto plate thus avoiding premature heating
Inventor: LANGE WOLFGANG
IPC: B27N3/20
Filed: 1972-12-19
Abstract: Fibre board, chipboard or similar panels which are to be faced with resin-impregnated decorative sheets are laid in a rapid operating press upon lateral supports, extending along two opposite sides, pref. the longest sides, of the press and arranged to pivot about external axes parallel to these sides. These supports are thus mounted external to the press but slope inwards and upwards to a position beneath the edges of the panel assembly; as the bottom, heated plate of the press ascends, it throws these supports outwards clear of the press so that the panel assembly is dropped onto the hotplate only just before the press closes. Pref., the edges of the lower plate which contact the supports are fitted with rollers, cam surfaces, etc. to assist the ejection of the supports.

Title: Scissors action clamp for pivoting or tilting window movement - is hinged to fixed frame portion and slides in slot in moving section
Inventor: FRACH WERNER
IPC: E05D15/52
Filed: 1973-06-15
Abstract: The scissors clamp maintains the window etc. in a required tilted position. One end of the first scissor arm is hinged to a pivot point on the stationary frame, and the swivel axis of the movable frame also passes through this point. The other end of the arm is displaceably held in a slot on the upper flank of the movable frame. One end of the second scissor arm is hinged to a pivot point on the movable frame, while its other end is displaceable in a slot in the upper flank of the stationary frame. When seen in closed or swivel position, the pivot point of the second arm on the movable frame, is at a distance to the swivel axis of that frame. This distance, the corresponding end pint of the slot in the stationary frame, and the length of the second arm are selected, so that the second arm, when its end has reached the slot end, determines the desired, max. tilt position, and max. swivel position.

Title: Application of solidifiable liquid mass to cylindrical surface - involves rolling between two paths, one with constant thickness layer of mass
Inventor: JIPPA PAUL-ARMIN DIPL-ING
IPC: B05D1/18
Filed: 1973-09-07
Abstract: A liquid solidifiable mass of lacquer, adhesive or plastics is applied to part of the surface of a cylindrical workpiece, which is simultaneously rolled on the guide plates which move relative to each other; at least one plate produces a constant thickness layer of the mass, which is taken up by the workpiece during contact and transferred to its surface. Pref. the workpiece is positively guided between the plates which are resiliently pressed against is and the surfaces are rolled one on the other to produce the rolling motion. Application of an exact thickness of material is possible with reproducible width in both end regions; mass production is possible with different workpiece dimensions.

Title: Thermal insulating spacers for coaxial tube feeder systems - carrier tape has reinforcement permitting accurate dimensioning of form
Inventor: KUYPERS HUBERT
IPC: B29B7/00
Filed: 1974-03-09
Abstract: The parent patent described a process for the continuous prodn. of spacers for thermally isolating with synthetic foam, coaxial tube systems consisting of at least two concentric corrugated tubes for transporting fluid or gaseous, heated or cooled media, in which the expandable mixt. of synthetic matl. is delivered on to a "U"-shaped carrier band, allowed to expand freely at right angles to the carrier, and simultaneously any foam projecting beyond the reqd. height of the spacers, is skimmed off. In this addn. the continuously moving paper carrier tape is provided first of all, on its surface turned away from the foam, with a reinforcing strip, and is then folded in a "V" with its legs subtending an angle of more than 90 degrees to the base. The legs are then closed in to an angle of less than 90 degrees so that the tape kinks sharply, and finally the "U" profile is calibrated exactly. Possible to produce continuously, spacers with an exact rectangular or square section.
