Title: Stabilised wing for hang glider - has porous air panels under wing behind leading edge
Inventor: ZIMMER HORST
IPC: B64C31/028
Filed: 1990-10-05
Abstract: The wing of the hang glider has a hollow shape near the leading edge. The upper (29 and lower (3) wing surfaces enclose a trapped space which forms the wing shape.  The lower surface has porous panels (5) behind the leading edge to equalise any pressure differences under the length of the wing. The porous panels can be made from gauze inserts.

Title: Method for obtaining data which determines full sidereal times e.g. sunrise - broadcasting sidereal time taken from statutory time using radio clock transmitter and has storage memory pref. ROM or PROM provided in radio clock receiver
Inventor: HILBERG WOLFGANG DR ING
IPC: G04G9/00
Filed: 1991-10-04
Abstract: The method involves storing the data determined for the sidereal time, e.g. the times for the sunrise and the sunset, for each day of the year in the memory. The pulse assembly reproduces the received date, converted such that it agrees with the associated address of the special storage memory. The process enables the determined sidereal dates associated with the date to be read out and indicated. The information is also stored which is related to a leap year. Each year number received is monitored, whether it is to be handled as a leap year or not. Separate lists of the date related times, for leap years and normal years are stored. ADVANTAGE - Sunrise and sunset times can be of use e.g. for lighting up times, putting clocks forward or back or raising roller blinds. Timing can be more reliable than poor light which may relate to cloud rather than clock time.
