Patent DE-4138982-A1 (DE)
Inventor: HAAS THOMAS DR
IPC: C07C45/64
Filed: 1991-11-27
Abstract: A process for the production of 3-hydroxyalkanals, more particularly 3-hydroxypropionaldehyde, by hydration of the basic 2-alkenals, more particularly acrolein, in the presence of a solid catalyst containing acid functional groups. The catalysts are based on an inorganic support containing basic activity centers (which are at least partly occupied by a polybasic acid, of which the first pKs value is between 0 and 3, in a form in which it cannot be removed by water) enables the hydration to be carried out with high selectivity. At the same time, the disadvantages of known organic fixed-bed catalysts are avoided. Preferred catalyst are based on pyrogenic titanium dioxide with phosphoric acid fixed thereon.

Title: GPS satellite-synchronised chronometer with local time display - uses XTAL-controlled clock and interpolation signal processor
Inventor: KROGMANN UWE
IPC: G04R20/06
Filed: 1992-01-29
Abstract: The radio synchronised clock contains an antenna (10) and radio receiver (20) consisting of pre-amp (22), IF section (24) and a crystal oscillator (26). The oscillator maintains local time with error delta tB (28). GPS satellites (12,14,16,18) transmit synchronising signals and time codes. By determining the relative timing of these signals, local time and position are generated by processor (30). An error estimate for delta tB is output (32) to a time generator (34). Longitude (36) is output to time-zone store (38) which outputs the difference between the Local Mean Time and GMT to the time generator. By these means a chronometer is realised which automatically indicates local time worldwide and with satellite time synchronisation. USE - Ship navigation and chronometer.

Title: Reconnaissance aircraft with adaptive control of aerodynamic surfaces - operates in conditions providing for centre of mass to remain close to centre of aerodynamic forces
Inventor: DORTOMB BERNARD
IPC: B64C39/02
Filed: 1992-04-10
Abstract: The fuselage carries a wing assembly divided into two regions at selected distances from the centre of mass, with distributed redundant control surfaces. These regions are arranged symmetrically w.r.t. the longitudinal plane of the fuselage. The propeller (MP) and control surfaces (G) are linked to a controller (MC) responsive to signals from e.g. an altimeter, gyrometer, accelerometer and magnetic heading sensor.
