摘要:
The invention regards a mitre cutter arrangement for cable ditches comprising a mitre ruler (Fig 2) to be clamped to the cable ditch (Fig 9) in order to receive a saw arrangement (Figs 3 and 4) running along the mitre ruler, said saw arrangement when displaced being guided by guide means, one of which being applied on the saw arrangement and the other one, cooperating with said first mentioned guide means, being applied on the mitre ruler. The mitre ruler and the cable ditch are clamped to a mitre table, such that the cable ditch will form the desired angle with the longtudinal direction of the mitre table and the mitre ruler, respectively. In the bottom (10) of the mitre ruler a groove (12) is provided for receiving the saw blad (17) of the sawing arrangement, said saw blade running through the groove and into the cable ditch, which is clamped under the mitre ruler.

The present invention regards an operation table for big animals which is immersable into a deepening (11) in the floor (10) of the operation room in such a waythat, in the position or readiness of the operation table its table proper intended for the execution of the operation (16) will be situated at least substantially in flight with the level of said floor (10) but that it may be elevated into a convenient working position. The operation table comprises a support (12) and the table proper (16) for execution of the operation. The foundation is supported by the bottom of the deepening (11) by means of a scissor elevation device (13), and the table proper (16) is supported by the foundation (12) by means of a second scissor elevation device (14). The height of the foundation (12) along with the means for operating same is so chosen, that the foundation will, in its elevated position, be in level with the floor (10) in the operation room.
