Patent GB-2188162-A (GB)
Title: Viscometer
Inventor: FERGUSON JAMES
IPC: G01N11/14
Filed: 1986-01-29
Abstract: The viscometer 200 comprises a cup 14 and a plug 16 which define a sample space 12 between them. To effect measurement, the cup 14 is rotated. Fluid in the space 12 provides a viscous coupling to the plug 16 which rotates to a position in which a torsion mounting 26 provides a counterbalancing torque. The size of the counterbalancing torque and hence the position of the plug in balance, depend on the viscosity of the fluid. When measuring viscosity of fluid flowing through chamber 18 a collar 56 is allowed by ratchet mechanism 60 to rotate with the cup 14, but when the rotation of the cup is reversed to recharge the sample space 12 the collar is held stationary by the ratchet mechanism and piston pumps 40 rotating with the cup are reciprocated by cooperating cams 66 on the collar 56 to recharge the sample space 12 with liquid representative of that currently flowing through chamber 12. A centrifugal pump actuated by high speed rotation of the cup may be used instead of the piston pumps. <IMAGE>

Title: Improvements in utility knives
Inventor: GILBERT RICHARD
IPC: B26B5/00
Filed: 1987-05-08
Abstract: PCT No. PCT/GB88/00341 Sec. 371 Date Jan. 8, 1990 Sec. 102(e) Date Jan. 8, 1990 PCT Filed Apr. 29, 1988 PCT Pub. No. WO88/08774 PCT Pub. Date Nov. 17, 1988.A utility knife comprises a lower elongate part shell 1 and an upper such part shell 3 forwardly fitted with interengaging wedging surfaces whereby they clamp together on relative longitudinal movement. This movement is achieved by turning nut 2 on shank 8 to bear on wall 30. The loosening of the nut 2 to unclamp the part shells and thus permit blade 43 to be pushed forward with slider 42 by pushbutton 41 does not separate the part shells 1 and 3 since the end spur 9 of the shank 8 still rides on arresting web 37. Maximum unscrewing of the nut, however, permits separation e.g. for access to stack of spare blades 60 resiliently held at 59 in the rearward part of shell 1 (now unencumbered by the conventional screw-shank), but does not lead to loss of nut 2 because of a complementary detent configuration 25 at the end of the shank and in the end wall 2a of the nut prevents complete nut/shank separation. Spur 9 can be upwardly sloping at its underside and thus constitute an auxiliary clamping means for part shell 1 against part shell 3.
