Title: Animal fodder pellets from rotary twin-punch machine - by extruding material inside punches for cutting into short lengths
IPC: B01J2/26
Filed: 1979-11-21
Abstract: The one cylindrical punch of a pair in a plant for the production of small pressed pieces of material, has bores through its mantle which coincide with the surface zones between two bores in the other punch, where their surfaces are brought together in the nip. The material is fed from a hopper into the nip between the two punches and is extruded into their interior to be cut into short lengths. Used for the prodn. of animal fodder in pellet form, whilst avoiding the grinding action on the meal occurring in conventional machines with freely rotating pressing rollers and a single punch. The elimination of this shortcoming, results in higher output. In addition, less power is required and the wear on the punches is reduced by the much larger open surface.
Patent NL-8101279-A (NL)
IPC: A61C19/04
Filed: 1981-03-16
Abstract: A measuring instrument for the depth of the periodontal cavity comprises a probe needle (2), a needle holder (3) and a handle (1). The needle (2) with the needle holder (3) is restrictedly pivotable from a start position determined by an abutment against the action of a bias spring, the deformation of which caused by the needle movement causes no substantial change of the spring force. To this end the needle holder (3) and the handle (1) each are attached to parts of a hinge (4). The hinge parts (5, 6) are biased to the closed position of the hinge (4) by a spring (8, 12, 13, 14) with a spring characteristic which is substantially flat at least within the restricted pivoting range of the hinge. 
<??>In this manner the hinge of the measuring instrument can be made compact and especially flat whereby the user of the instrument has a good view on the probe position under all circumstances. The measuring instrument is constructively simple, can be manufactured relatively cheap and can be more easily sterilized.
Patent NL-8103288-A (NL)
Title: Flowmeter using temp. detection - uses electricity meter to measure current needed to maintain temp. difference between two temp. sensors
IPC: G01F1/698
Filed: 1981-07-09
Abstract: This flowmeter uses the cooling effect of the liq. flow to measure the flow rate. A grid in the pipeline straightens the flow, which goes through an insulated sleeve over a first temp. sensor over a hot wire and over a second sensor. The current flow through the wire is fed through an electricity meter. The temp. difference between the sensors is kept constant by a controller so that the power used to heat the wire is directly prportional to the liq. flow rate. The voltage and current coils in the electricity meter turn a disc which, in turn, operates a totaliser. The system is calibrated by adjusting a potentiometer.

Patent NL-8600450-A (NL)
IPC: G11B20/18
Filed: 1986-02-24
Abstract: A method and apparatus for storing and reading digital information, in which the recorded information is protected by a double symbol correcting code involving interleaving between the codes and also employing an additional, optional error correcting code. The information is organized in sectors, which are arranged such that following the synchronization and header information sub-header information is provided to indicate different sub-modes of operation of the playback apparatus. During playback, when a first sub-mode indication value is detected, this means the sector contains further error protection information, that is, the optional error correcting code, for which purpose a special decoder is activated. When the sub-mode detector detects a second sub-mode indication value, this means that further user information is present at the location where the optional error protection information would have been, and the special decoder is not activated.

Abstract: The rabies vaccine is prepared by growing rabies viruses in animal nerve tissue, mainly in poultry embryos, harvesting the viruses from the nerve tissue or from the heads of the embryos, concentrating the viruses, inactivating them and making up to the vaccine, wherein homogenisation of the nerve tissue or of the embryo heads with a mixer is avoided on harvesting the viruses, and thus damage and fragmentation of the viruses is prevented, in that the nerve tissue or the heads of the embryos or their contents are comminuted without damaging cells, the complete, live and viable viruses are washed out of the resulting cell suspension, the resulting virus suspension is concentrated, delipidated by extraction with an organic solvent which is immiscible with water, and then further selectively concentrated. A myelin-free rabies vaccine is obtained from poultry embryo head tissue containing rabies viruses by the process described above.
