Title: Cavity wall mortar guard screen - consists of vertical mortar catching sheet and horizontal fitted insulating seal in cavity
Inventor: ZABOROWSKI GEB HUETTIG ERNA
IPC: E04B1/70
Filed: 1978-01-14
Abstract: The gap is cavity walls between a heat insulating inner shell and a brick wall outer shell is maintained by distance pieces which help to create a barrier against moisture, to act as heat insulation and to retard the diffusion. To prevent mortar during the building of the outer wall from falling into the intended gap, it is suggested to erect a mortar guard screen on the brick wall side. The brick wall shell can now be built in one fast non-stop operation.

Title: Applying multi-coloured flock designs onto a glue-coated base - by spaying electrically charged nylon flocking through suitably contoured textile or plastics film templates
Inventor: HOLMQUIST NILS THOMAS BERTIL
IPC: D04H11/00
Filed: 1978-07-04
Abstract: High voltage is generated between an appliance contg. a supply of flocking, and the zone selected for flocking, so as to electrically strongly charge the flocks. A non-conductive cloth, plastics film or the like is arranged above the substrate at a distance from it. The cloth or film is mounted in a frame and has an opening whose contours correspond to a section of the selected zone to be flocked. Electrically charged flocking is applied, through the opening, onto the binder-coated zone. The frame is then replaced by another frame with cloth of film stretched over it but this has opening(s) of different contours through which flocking of other colours are applied onto the substrate. In this way, relatively complex, multi-coloured, patterns or designs are achieved upon the substrate. Used e.g. in the mfr. of multi-coloured, patterned, wallpaper, fabric for apparel, fashion articles, etc. with pleasing flock design. Process is relatively simple. No expensive tools e.g. special flock spraying guns, are required. Unskilled or semi-skilled labour can successfully execute the process.

Title: Fluid flow velocity vector measurement - uses nulling summation of peripheral rotation vector and flow from rotating heated wire
Inventor: LEHMANN BERNHARD DIPL ING
IPC: G01P5/12
Filed: 1979-10-23
Abstract: The appts. includes a heated wire set in a circular motion with a peripheral speed vector to which the measurement flow velocity vector is added, resulting in a relative velocity. This results in a periodic electrical signal in the heated wire. The periodic electrical signal is nulled by varying the revolution rate and if necessary the inclination of the probe to the circular motion. The flow velocity vector is then fully represented by the measurable parameters of the wire peripheral velocity vector. The arrangement for calibration-free measurement of flow speed vector magnitude, direction, and sign is applicable in air conditioning and ventilation technology as well as meteorology where significant convection and stray currents occur. It differs from conventional arrangements in using an uncalibrated heated wire sensor.
