Title: Thermal-insulation body.
IPC: E04B1/78
Filed: 1980-07-15
Abstract: A heat-insulating body such as a heat-insulating slab is made whose insulating and heat-absorbing material includes a fine powder, in particular a silica aerogel which is pressed to form the body. To carry out the pressing operation a sack-like sheath is required but between the sheath and the insulating material a separating agent is provided which results in the fact that the surface of the insulating material does not intimately engage with the sheath which is for example of glass fibre fabric, the sheath being movable with respect to the insulating material after the pressing operation. Apart from the fact that the sheath can be removed for any cases where it would be a cause of disturbance, additionally the insulating body provides improved bending properties and even when made with a high pressing rate has a homogeneous structure. To make the insulating body the separating agent may be applied to the inner surfaces of the sheath, the particulate insulating material then being introduced and the sheath sealed, whereafter pressure is applied.

Title: Process for the manufacture of flavour concentrates from vegetable and/or animal substances.
IPC: A23L13/30
Filed: 1981-05-13
Abstract: The material for extraction is extracted with physiologically acceptable fat or fat-like solvents in the presence of water. This is carried out in a closed pressure vessel at elevated temperature. The amount of water must be such that the water activity corresponds to a aw value of not less than 0.5.

The resulting flavour concentrate can be used as a semi-finished product in the manufacture of sauces, soups, seasoning mixes and the like or can be sold as a finished product. The material which has been subjected to the extraction process is in general completely tasteless.

Title: Radiation-sensitive semiconductor device
IPC: H01L31/10
Filed: 1981-07-03
Abstract: In a radiation-sensitive semiconductor device, for example a quadrant diode, having several rectifying junctions, the mutual distance between these junctions can be considerably reduced by keeping the junctions cut off by means of circuit elements in such manner that associated depletion regions touch each other.

With this arrangement, low crosstalk and good high-frequency properties can be realized. Furthermore, the semiconductor body in which the rectifying junctions are realized may comprise further circuit elements, which permits integration of the radiation-sensitive semiconductor device with other elements.
