Patent EP-0306325-A1 (EP)
Inventor: COLLINS BRIAN STUART
IPC: E04H12/20
Filed: 1988-09-02
Abstract: A telescopic mast is provided in kit form with stays wound on reels in a predetermined order. This order is such that when erecting the mast it is only necessary to walk between the mast and pegs fixed into the ground and not between two pegs at a distance from the mast. This minimises the amount of walking which is necessary in erecting the mast. 
     Clamps between between sections are formed from a strap (52) around the outer (34) of two concentric sections. The ends of the strap (52) are secured together and attached to a member (56) with a pressure face. A camming device (76) between this member and the mast which acts against the pressure face and the mast enables the strap (52) to be tightened thus gripping the outer mast portion against the inner mast portion. 
     The top section of a telescopic mast is less inherent rigidity than the bottom section and this it is preferable to construct it from material with a greater resistance to longitudinal bending than the lower section and to vary the resistance of the intermediate sections accordingly.

Abstract: A signal processing system for hearing aids estimates the absolute quantity of noise in each of a plurality of frequency bands. The audio gains are adjusted so as to minimize the effect of upward spread of masking, wherein noise in lower frequency bands decreases the intelligibility of speech sounds in higher frequency bands. 
     The noise level in each frequency band is estimated by monitoring the amplitude distribution of sound events in that frequency band.

Inventor: SOELKNER GERALD DIPL-ING DR
IPC: G01H9/00
Filed: 1989-05-12
Abstract: Since the models for calculating the wave propagation in surface wave components do not take all physical effects into account, deviations between actual component behaviour and desired component behaviour frequently occur. To improve these models, it is therefore necessary to represent the wave field in the component true to phase or to measure the parameters characterising the elastic wave in resolved form. It is proposed to record quantitatively the deflection of the component surface caused by the elastic wave, by measuring the deflection of a pulsed laser beam. As radiation source, use is made in particular of a mode-coupled Nd:YAG laser with downstream pulse compressor.

Abstract: Air which has had water vapour and carbon dioxide removed therefrom is introduced at about its dew point into a higher pressure distillation column 4 through an inlet 8, and is separated into oxygen-rich and nitrogen-rich fractions. A stream of oxygen-enriched liquid is withdrawn from the higher pressure column 4 through an outlet 18 and is introduced into a lower pressure distillation column 6 in which it is separated into oxygen and nitrogen. Nitrogen gas is taken from an outlet 32 at the top of the lower pressure column 6 and is employed in a heat pump cycle in which it is compressed in compressor 34, cooled in heat exchanger 2, condensed in reboiler 26 to provide reboil for the column 6, and returned to the top of the column 6 as reflux. A part of the liquid nitrogen stream leaving the reboiler 26 is diverted from the flow to the top of the column 6 and is pumped into the top of the column 4 as reflux. The operating pressures of the columns 4 and 6 are thus able to be set independently of one another.

Abstract: A communication system includes a plurality of machines 21-24, 30, 33-35, etc) having unique identifiers and interconnected by a network of message switching nodes (10-14, 40, etc). Each node includes a dynamic routing table containing a plurality of machine identifiers and, for each, the next place in the network where a message to that machine should be directed to. 
     The system includes a Directory Information Base (DIB) which includes a machine listing. For each machine, the listing has an entry including attributes of the machine. The attributes include updating and routing information. The former identifies the parts of the system need to be be updated to maintain consistency if some part of the entry is changed, including in particular information as to which nodes require their dynamic routing tables to be updated in response to a change in that entry (as if the routing tables were part of the DIB). The latter gives node identifications and routes from those nodes to the potential receiving machines. The DIB includes updating means which, on a change in an entry, use the updating attribute of that entry to transmit updating information to the rest of the DIB, in a format defined for the whole of the DIB. Such information is thus also sent to the relevant nodes. 
     Each node includes means for updating the routing table in response to such transmissions from the updating means, including format conversion means for converting such transmissions to the format of the routing table.
