Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
82 words
A material mixer comprising a vessel, mixing screw means in said vessel, said screw means being driven in an orbital path about its own axis and about the inner wall of said vessel; means journalling said screw means in said vessel, comprising a pin ball fixed to said vessel and complementary means on said shaft, operatively associated with said pin ball; said pin ball journal further comprising temperature feeling means, whereby undesired changes in temperature of the pin ball journal are measured.
Claim 2
Dependent Claim
82 words
A material mixer comprising a vessel, mixing screw means in said vessel, said screw means being driven in an orbital path about its own axis and about the inner wall of said vessel; means journalling said screw means in said vessel, comprising a pin ball fixed to said vessel and complementary means on said shaft, operatively associated with said pin ball; said pin ball journal further comprising temperature feeling means, whereby undesired changes in temperature of the pin ball journal are measured.
Claim 3
Dependent Claim
19 words
A material mixer according to claim 1 characterized in that said temperature feeling means are in said pin ball.
Claim 4
Dependent Claim
20 words
A material mixer according to claim 1 characterized in that the temperature feeling means is arranged in said complementary means.
Claim 5
Dependent Claim
35 words
A material mixer according to claim 1, further comprising closure means operatively associated with said complementary means and retaining said pin ball against undesired separation; said temperature feeling means being arranged in said closure means.
Claim 6
Dependent Claim
21 words
A material mixer according to claim 4, wherein said closure means further comprises a ball shaped socket enclosing said pin ball.
Claim 7
Dependent Claim
24 words
A material mixer according to claim 1, wherein said temperature measurement further comprises an alarm whereby said undesired temperature changes can be made known.
Claim 8
Dependent Claim
31 words
A material mixer according to claim 1, wherein said complementary means is a socket having a cylindrical slide bushing freely slidable over said pin ball axially of said mixing screw means.
Claim 9
Dependent Claim
53 words
A material mixer according to claim 1, wherein said complementary means is a socket which includes a shouldered shaft having a first part adjacent said pin socket, said first part being of a diameter less than that of the socket and is journalled in said mixing screw means, said journal comprising radial rollers.
Claim 10
Dependent Claim
23 words
A material mixer according to claim 8, wherein said pin socket extends in a bore of the mixing shaft, said bore being sealed.
Claim 11
Dependent Claim
46 words
A material mixer according to claim 8, wherein said shouldered shaft is provided with a second part of a diameter smaller than that of the first part, said second part including axial thrust journal means and further radial roller means journalled in said mixing screw shaft.
