Title: Machine for processing belly flaps from a front part of a fish
Inventor: KRISTINSSON SIGURDUR
IPC: A22C25/00
Filed: 1991-06-19
Abstract: ABSTRACT          The invention regards a method and a machine for processing belly flaps from a front part after socalled "parting" of the fish into two parts, a rear part and a front part 1 (fig. 1), whether or not the pectoral nose 9 and the pectoral bond 20 are cut, the fish killed by a cut through the pectoral nose and the belly cut all the way, separating the lower end of the pectoral bones.          According to a patent application (Iceland nr. 3597) in the name of the same inventor, it is known to move by spiked chain at each side the front part I with the belly foremost and the head 18 farthest back, along a fixed straight track to a fixed U-formed slide, a kind of a belly scraper 16, at the end of the spiked chains. The belly 3 is threaded upon the belly scraper 16, which scrapes the inside of the belly 3, so that the organs get loose from the front part 1 and are moved into the belly scraper 16. The front part of the belly scraper according to the invention has an ele-vation 26 in the floor, and cuts the pectoral nose 9 from the gills 10 and the tongue 8, so that the tongue 8 is moved into the belly scraper 16, whereas the neb itself pierces downward and out from the head through the pectoral nose 9. The jaw bones are broader than the belly scraper 16 and are therefore on the top of and are moved along its upper edge.          The belly flaps 12 are outside the belly scraper 16. Outside the belly flaps 12 are the slides 31 for cheeks, inclining upwards in the moving direction 32, 33 and elevate the gill lids 14, so that they protrude from the head like wings (fig. 13). There are knives 30 under the foremost end of the slides 31, which cut towards the belly scraper 16, into the belly 3 and throat of the head 18, above the upper edges of the belly scraper 16. In that way the pectoral nose knife 17 cuts the pectoral nose 9 from the head 18, and the horizontal knives cut the belly flaps from the spine 2 along the upper edges of the belly flaps 12. In this way the belly flaps 12 are free and fall down into a tub for belly flaps, whereas the head is moved forward in a known way by means of a spiked chain 29, along the belly scraper to its end, and the head 18 draws the organs to a tub for heads at the end of the spiked chain 29.          The pectoral bones 19 belong to the belly flaps 12 and fall down into a tub for belly flaps, material for jam, where the pectoral bones 19 are separated by pressing the flesh through a sieve, where the bones can not get through.

Patent CA-2048883-A1 (CA)
Inventor: PICKERT WERNER
IPC: B24B49/14
Filed: 1991-08-09
Abstract: Abstract of the Disclosure The present invention discloses a method and a  device  for  preventing  thermal  damage  of workpieces due to heat developed by a grinding process.  According to the method the temperature increase at the surface being ground is determined and the resulting actual value is compared to a reference value which has been established under the same grinding parameters with a grinding disk that  caused  thermic  damage  to  the reference workpiece.    During  manufacture,  the  grinding process  with  the respective  grinding  disk  is interrupted as soon as a temperature increase has been detected that corresponds to the respective temperature causing thermic damage.  The reference value  is  determined  such  that  it  includes  a certain safety margin.  The determination of the actual  value  and  the  reference  value  may  be accomplished by using geometric deformation of the workpiece that result from the temperature increase due to the grinding process.  The device is characterized by special measuring devices for measuring  the  geometric  deformations  of  the workpieces.

Abstract: The present invention is to provide a circuit for detecting humidity in which occurrence of the temperature drift can be inhibited by a simple means and therefore which is able to detect humidity precisely without regard to the temperature of the atmosphere. In a humidity detection circuit including a bridge circuit containing temperature elements, the bridge circuit is connected with a series of a third resistance R3, a current controlling element and a power supply in this order, while a series of fourth and fifth resistances R4 and R5 is arranged in parallel with the series of the R3 and the bridge circuit. In addition a junction between R4 and R5 and another junction between R3 and the bridge circuit are connected separately to a voltage comparing circuit, the output of which is inputted into the current controlling element. In this arrangement, a control section is provided to detect the potential of the junction between the bridge circuit and the third resistance R3. The humidity detection circuit, based upon the detected potential, changes the resistance value of resistance R5 to an optimum level at which the temperature drift does not occur.
