摘要:
A device for optical analysis of a specimen, especially a blood sample, is in the form of a dish, a translucent plate-shaped portion, which has a specimen-receiving surface, essentially constituting the bottom of the dish, and a frame, which engages the plate-shaped portion, forming its wall. To catch surplus liquid from the specimen-receiving surface, especially when receiving, smearing, spinning or coloring the specimen, an absorbing material is arranged in a loop along the circumference of the plate-shaped portion. The design of the device permits safe and easy handling of specimens that are injurious to health.

For carrying out a method to displace an object from a resting position to to a working position or vice verse, a device (1) is arranged comprising a screw (3) with two threads (7, 9) with different pitches and a body (2, 4) with internal threads matching the threads of screw (3). The body is shaped in two parts (2) and (4), which are arranged to be able to be displaced relative to one another in the axial direction of the screw (3), whereby a changing from one thread to another thread can be done by changing the distance between said parts (2, 4) of the body. The screw (3) is arranged to a first object and the body (2, 4) to a second object. In utilization of the method the object can be rapidly displaced to the resting position or working position by the fact that the screw and body are engaged with one another in the one thread or a coarse thread and when needed the screw and body are brought to change to an engagement with one another in the other thread or a fine thread, for example by an increased tightening force action.

The invention relates to an air cleaner in the form of a cyclone separator comprising a cyclone chamber (2), a gas-feeding nozzle (11) which is directed tangentially to the wall (12) of the cyclone chamber, and a gas outlet (7). The invention is characterized in that the cyclone separator comprises a liquid trap (9, 13) arranged in the wall (12) of the cyclone chamber. Further the nozzle and the liquid trap extend along substantially the entire height of the cyclone chamber. The liquid trap comprises axial grooves (13) and a chamber (9) having an inlet gap (15) which connects the chamber (9) with the cyclone chamber (2) for diverting liquid droplets.

In automatic evaluation of cereal kernels or like granular products handled in bulk, the kernels are conveyed on a vibrating conveyor belt (15). Owing to the vibrations, the kernels are spread and settled in grooves (14) in the belt so as to be oriented in essentially the same direction. A video camera (40) produces digital images of all the kernels on the belt. The kernels are identified in the images, and for each kernel input signals are produced and then sent to a neural network based on picture element values for the picture elements representing each kernel. A neural network then determines which of a plurality of predetermined classes that each kernel belongs.
