Patent EP-0149100-A3 (EP)
IPC: G02C7/02
Filed: 1984-12-05
Abstract: A multifocal spectacle lens is described with a high positive focal power, with a convex front surface which comprises an aspheric focal portion with an additional near segment, a transition zone surrounding the focal portion and a rim zone, and with an inside surface which forms an afocal margin together with the rim zone. The multifocal spectacle lens according to this invention is characterized by the fact that the near segment has an aspheric design and is separated from the focal section above it by a dividing line which has an approximately straight course. The main meridian of the near segment carries over into the main meridian of the focal section above it continuously and practically without any jump. In an advantageous further design of the spectacle lens according to this invention, an aspheric intermediate portion is provided between the near segment and the distance portion being separated from the distance portion by a dividing line with an approximately straight course and whose vertical main meridian also carries over into the main meridian of the distance portion continuously and practically without any jump.

Abstract: Apparatus for refrigeration and storage of products, 
especially liquid food products, such as milk, in an insulated 
tank (10). In the bottom of the tank there is disposed an 
evaporator (12) constituting part of a cooling coil in which a 
refrigerant circulates for keeping the tank contents cold. The 
product is supplied to the tank batchwise during certain time 
periods and the tank is adapted to hold several such batches 
of the product. To obtain a maximum average temperature of 
the product and the refrigerant for cooling with a minimum of 
energy consumption there is connected to the tank an insu­
lated container (24) adapted to hold a batch of the product to 
be kept cold, said container (24) being itself provided with an 
evaporator (28) included in a cooling coil for cooling said 
product batch to the desired low temperature at which the 
product is kept cold in the tank (10). A transferring equipment 
(36) is adapted automatically to transfer the contents from the 
container (24) to the tank (10) when said temperature has been 
attained.

lower range. Means 51 - 55 measure the slope of engine 
output with respect to the perturbed control parameter 
in a first mode for the upper engine speed range and in 
a second mode for the lower range. The measured slope 
issued by means 37, 45 - 47, 57 - 61 to correct the 
engine control parameter. Memories 45 a  - 45 d  
corresponding to each cylinder combination are updated

Title: Production of rapeseed protein materials
IPC: A23J1/14
Filed: 1988-04-18
Abstract: There is disclosed a process of treating meal containing vegetable proteins. This process includes the step of extracting the meal at an extraction and washing zone 10 with a suitable aqueous solvent, e.g. aqueous sodium hydroxide, in which the vegetable proteins are soluble to obtain an extraction solution. The wet residue is suitably separated, e.g. by filter 12, from the extraction solution, and dried in dryer 13 to provide a meal residue C. The solubility of the dissolved protein in the extraction solution is then adjusted in zone 14 to precipitate at least some of the protein and therefore obtain a precipitated protein fraction and an unprecipitated protein fraction in solution. The precipitated protein fraction is then separated from the protein fraction in solution, and the unprecipitated protein fraction is separated from the undesirable components in the solution by membrane processing in a zone 18. Each of the protein fractions is then suitably dried in dryers 17 and 19 to recover the proteins. This process provides a commercially viable process for producing pure, good-grade protein from rapeseed.
