Title: Characterising overflown terrain using signal from FM/CW probe
Inventor: HETHUIN SERGE
IPC: G01S13/935
Filed: 1991-12-12
Abstract: The method involves transmitting a signal from a FM/CW probe towards the terrain and analysing the shape of the spectrum of the beat signal produced by the probe in the frequency domain to characterise the terrain. Information about the reflection properties of the terrain is derived from the shape of the spectrum of the beat signal. A value representative of the reflection properties is derived from the measurement value of the amplitude of the spectrum as a measure of the reflection properties in the vertical direction from the frequency spread as a measurement value representing the backscatter diagram of the overflown terrain.

Title: Cathode ray tube disposal - using crusher followed by metal separator and fine grinder and sieve system to give three fractions of particle sizes
Inventor: KOTTMEYER JOST
IPC: B03B9/06
Filed: 1991-12-18
Abstract: To dispose of cathode ray tubes they are initially broken down in a crusher and the fragments are carried out by a conveyor through a separator to remove coarse metal matter. The glass fragments are finely ground and they are sieved into three fractions of different particle sizes. At least the fraction with medium sized particles, mainly of glass, is passed through a further separator for any metal matter present to be separated. The fraction mainly of glass from the sieve or the metal separator is passed by vibration into a container for transport. The CRTs are squashed before they are fed to the crusher. All the stages to reduce the CRTs into fragments are effected in an underpressure. ADVANTAGE - The method disposes of CRTs without affecting the environment and gives material which can be recycled with a high purity level.

Title: Cyclone reverse flow sub-assembly optimises separation of hot fluid phases - by reverse flow through ring jet followed by vigorous expansion and condensation
Inventor: VEDDER KARL FRIEDRICH
IPC: B04C7/00
Filed: 1992-06-11
Abstract: A hot fluid jet passes through a diffuser (4) within a cyclone vessel (15) which separates the phases of a working medium in a partial process of condensate expansion with high steam surplus. The diffuser (4) funnels into a jet sub-dividing assembly (5,6,8), in which the working medium mass flow is reversed by at least 180 degrees. The novelty is that in this sub-assembly the two-phase working medium mass flow: is returned in one circular (12) surrounding diffuser (4) passage in contra-flow to the outer wall (4''); exits at the upper end of the diffuser outer wall (4'') within the cyclone vessel (15); and partially condenses on the inner mantle areas (19) of the cyclone vessel (15). Further low intensity working medium mass flow compression takes place in the jet sub-dividing assembly (5,6,8), while the jet is pumped through and pressure is raised in the largest free volume (15). A ring jet (9) is located within the sub-assembly (5,6,8) after the 180 degree directional change, and has jet passages oriented to the cyclone centre which increase the compression. USE/ADVANTAGE - The cyclone separates the phases of a working hot fluid medium. The arrangement optimises the performance of existing cyclone separators.

IPC: E02D19/18
Filed: 1992-09-08
Abstract: Together with the support (10), the sealing element (2) is lowered into a vertical ground slot (3). During lowering, the sealing element is rolled-off a drum (1) and secured to the frame of the support. Pref. the element is lowered by the support weight. The drum exerts a controllable resetting force onto the sealing element to be lowered into the ground slot. For the element lowering, a controllable force, opposing the resetting force and overcoming the resistance of filling material in the slot, is exerted onto the sealing element. USE/ADVANTAGE - Improved erection and film clamping for sealing wall.
