Abstract
Abstract In a pressure centrifuge for recovering protein from bones under recycling of the protein solution, the cover (11) of the centrifuge bowl is provided with an aperture without tightening members through which aperture water or recycled protein solution is introduced into the interior of the centrifuge bowl. This represents a more simple construction of the centrifuge than hitherto regarded as possible for centrifuges for said purpose.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
130 words
A centrifuge for recovering proteins from bones and having a centrifuge housing (2) designed as a pressure vessel, which is provided with a removable cover (3) and connected with a source of steam at pressure above atmospheric and which comprises a perforated centrifuge bowl (5) also provided with a removable cover (11), said bowl being secured to a vertical, rotatable shaft (8) passing through the bottom of the centrifuge housing, provision being made in the bottom of the centrifuge housing for a liquid outlet, characterized in that a pipe (12, 29) led through the centrifuge housing (2) or its cover (3) for feeding liquid to the interior of the centrifuge bowl opens above or extends without tightening members through a central aperture in the cover (11) of the centrifuge bowl.
Claim 2
Dependent Claim
130 words
A centrifuge for recovering proteins from bones and having a centrifuge housing (2) designed as a pressure vessel, which is provided with a removable cover (3) and connected with a source of steam at pressure above atmospheric and which comprises a perforated centrifuge bowl (5) also provided with a removable cover (11), said bowl being secured to a vertical, rotatable shaft (8) passing through the bottom of the centrifuge housing, provision being made in the bottom of the centrifuge housing for a liquid outlet, characterized in that a pipe (12, 29) led through the centrifuge housing (2) or its cover (3) for feeding liquid to the interior of the centrifuge bowl opens above or extends without tightening members through a central aperture in the cover (11) of the centrifuge bowl.
Claim 3
Dependent Claim
44 words
A centrifuge as claimed in claim 1, characterized in that the pipe (12, 29) for feeding liquid to the interior of the centrifuge bowl is led through the cover (3) of the centrifuge housing and opens above the central aperture of the centrifuge bowl.
Claim 4
Dependent Claim
126 words
A centrifuge as claimed in claim 2, characterized in that a lifter (23) pivoting about a bearing (25) provided with a central passage (30) and supported by a bracket (26) on the centrifuge housing is secured to the cover (3) of the centrifuge housing, and that the pipe (29) for supplying liquid to the interior of the centrifuge bowl (5) is led centrally through the cover (3) of the centrifuge housing and outside the cover is led along the lifter (23) to the bearing (25) and is in connection with the central passage (30) -thereof, said bearing (25) has a pipe coupling (31) which remains stationary when the cover (3) and therewith the pipe '(29) for supplying the liquid are raised by actuation of the lifter.
