Title: Photographic printing apparatus
Inventor: HOLLOWS ANDREW DAVID
IPC: H04N1/407
Filed: 1991-02-28
Abstract: A photographic negative or positive is illuminated by light of an adjustable colour eg from an enlarger head (4) and is observed by a video camera (7). The RGB signals are convened to digital form and then transformed using look-up tables in a personal computer (1), which produces on a monitor (10) a display of the illuminated image as it would be if it were to be used to produce a photographic print on paper having characteristics defined by the look-up tables. A small area A, B of the display is selected, compared with a reference image and its colour adjusted (manually or by feedback from the computer) to match that of the reference image. The reference image may be from another negative or it may be an area of some desired colour. Several different reference images may be used, separately compared with different small areas, the colour differences averaged and used to control the colour of the light. Once the colour of the light has been adjusted it may be used to produce a photographic print from the image, in the normal way. <IMAGE>

Title: Colour picture tube having shadow mask with tie bar grading.
Inventor: MARKS BRUCE GEORGE
IPC: H01J29/07
Filed: 1992-07-27
Abstract: A colour picture tube includes a shadow mask which has a rectangular periphery with two long sides and two short sides. The mask has a major axis (X), which passes through the centre of the mask and is parallel to the long sides, and a minor axis (Y), which passes through the centre of the mask and is parallel to the short sides. The mask includes slit- shaped apertures aligned in columns that are substantially parallel to the minor axis. Adjacent apertures in each column are separated by tie bars in the mask, the widths of the tie bars being graded in dimension. The grading is at least partially related to the amount of tie bar stretch occurring in a similar size mask having different tie bar widths. As disclosed the width of the tie bars measured parallel to the aperture columns is varied non-uniformly over the whole of the mask in the way shown in Fig. 6 to compensate for the distortions occurring in the mask as it stretches during doming. The variation may be derived from the observed distortions occurring in a prior art mask having a circular grading of tie bar width, Fig. 4 (not shown). <IMAGE>

Title: RF filters
Inventor: HASLER RAYMOND JENSEN
IPC: H03H1/00
Filed: 1993-02-04
Abstract: A radio frequency transmission line filter has an insulative substrate substantially in the form of a plate of dielectric material, a ground plane (10) formed by metallisation on one face (4) of the substrate, capacitor plates (8a, 8b) formed by areas of metallisation on the other face (2) of the substrate to form, in conjunction with the ground plane (10), capacitances, and coupled to the capacitances respective metallised short circuited transmission line stubs (6a, 6b) forming inductances. The inductances and capacitances together form transmission line resonators. To allow the designer a wide choice in capacitance and/or inductance values, the substrate is recessed in selected areas (16a, 16b, 20a, 20b) to bring the ground plane (10) to within predetermined distances of the capacitor plates (8a, 8b) or inductance stubs 6a, 6b). The ground plane (10) may be trimmed in the recessed areas to adjust component values. Frequency response of the filter may be modified by the formation or connection of a capacitor element between the transmission line patterns (6a, 6b). The bandwidth of the filter may be reduced by the formation of a longitudinal groove between the transmission lines (6a, 6b). A plurality of LC combinations may be connected in series to form a Chebychev low pass filter. <IMAGE>
