Title: Improvements in paper and other sheet material roll dispenser
IPC: A47K10/32
Filed: 1979-07-09
Abstract: A holder for toilet or like rolls which is capable of containing at least one reserve roll which can be quickly transferred to an in-use position once a roll in use becomes exhausted.

Title: Electronic device for compensating non-linearity in a gamma camera output
IPC: G01T1/164
Filed: 1980-02-07
Abstract: In a gamma scintillation camera 10, the output signals Ux, Uy represent non-linear functions of the geometrical coordinates x, y of the location of a scintillation event in the crystal. The outputs Ux, Uy of the camera 10 are fed respectively to one input of corresponding high gain differential amplifiers 11 and 12 whose outputs V and W are applied to corresponding inputs of a quadripole non-linear device 13 (Figure 4 not shown) as orthogonal deflection signals for a cathode ray tube. The location of a spot deflected thereby is sensed by an assembly of photodetectors 23 having the same distribution relative to the cathode ray tube screen as the photomultipliers of the camera 10 relative to the scintillation crystal. A weighting circuit 24 generates output signals Uv and Uw representing the barycentre of the photodetector outputs, which are fed to the respective other inputs of the differential amplifiers 11 and 12, thus completing a servo feedback loop. When the servo loop reaches an equilibrium state, the signals V and W provide corrected output coordinate values linearly related to x and y. <IMAGE>
