Abstract: 1291504 Navigational plotting device M W G WEBSTER 22 June 1971 [24 Oct 1970] 50649/70 Heading G1X A navigational plotting device comprises a flat base member 1 supporting a mirror 17, a pair of radial members 2, 3 and a pair of arms 7, 8 which, at their inner ends are pivoted to the base member 1 and at their other ends are constrained to move in slots 13, 14 in the radial members 2, 3, the arms 7, 8 being provided with mirrors 15, 16 which are arranged substantially parallel to the arms and perpendicular to the base member 1. In use, an observer holds the base member 1 horizontally and, looking towards an object, aligns a pointer 18 on the base member 1 with the object so that it is seen over the mirror 17. Each radial member 2, 3 is then rotated about a pivot 6 on the base member 1 until two further objects can be seen by the observer in the mirror 17 which receives the reflection of the two further objects from the mirrors 15, 16. The arms 7, 8 are then clamped relative to the radial members 2, 3 before the device is transferred to a chart. On adjusting the position of the device on the chart to align the pointer 18 and pointers 4, 5 on the radial members 2, 3 with the representations of the objects on the chart, the position of the pivot 6 indicates on the chart the position of the observer. The pivot 6 may be provided with a hole to receive the tip of a pencil. The base member 1, radial members 2, 3 and arms 7, 8 may be of transparent material which, in the case of the radial members 2, 3, may be tinted and the arm supported mirrors may be adjustable.

[Also in Division G1] A two-stage scale reading device for use in measuring lengths or angles comprises coarse and fine counting mechanisms 4, 5 with tens transmission and optical and mechanical means which drive the fine mechanism 5 and the number wheel 18 for the lowest decimal place of the coarse mechanism, the number wheel being turned back by an amount corresponding to the fraction of a measuring scale interval indicated in the fine mechanism. Motion of a machine tool slide is transmitted to the counting mechanism 4 by a pinion 7 engaging a rack 6 on the slide, chain gearing 8, differential gears 9, 14 and spur gears 15, 16 and 17, 18. To obtain a precise reading, the image of a graduation on a scale 1 on the slide is projected through a plane plate 20 and a micrometer screw 29 is rotated to move rack gearing 30, 32 and tilt the plate 20 until photo-cells 26, 27 receiving light from the scale are balanced as indicated by a magic eye 28. Displacement of the rack 30 rotates the differential gear 9 through a lever 34, thus affecting the coarse mechanism 4 and rotation of the screw 29 is conveyed to the fine measuring mechanism 5 by chain gearing 35. A knob 40 is used to reset the counters. In a modification, the micrometer screw 43, Fig. 4 (not shown), rotates a rhombic prism 41 to obtain a symmetrical setting in a photoelectric device above the prism. The latter device can be adjusted to read a scale at right angles to the scale 1. In a further modification, the number wheels of the counting mechanisms rotate brushes 53, Fig. 7 (not shown), to give a luminous indication on tubes 56. These indications can be repeated or printed. In further modifications, the scale co-operates with a displaceable grid or a scanning slit.

Patent GB-519769-A (GB)
IPC: C09K23/00
Abstract: 519,769. Emulsions and emulsifying agents. KING, A. June 20, 1938, No. 18299. [Class 1 (i)] In the preparation of dispersions of oils, fats, waxes and other water immiscible liquids using gelatinous inorganic metallic hydroxides or oxides as the emulsifying agents, improved fineness is obtained by adding surface tension reducers such as alkalis, soaps, oleic acid or montan wax in quantities small compared with the amount of hydroxide or oxide used. The emulsion may be prepared by precipitating the hydroxide with excess alkali, washing to remove most of the alkali, and homogenizing with the oil. In examples, kerosene and benzene are dispersed respectively by ferric hydroxide and aluminium hydroxide, the small amount of alkali being added before or after emulsification. In the case of a very pure water-immiscible substance, emulsification may be facilitated by first adding a trace of a saponifiable material such as oleic acid. For example, carbon disulphide with a trace of oleic acid is dispersed by agitating with a suspension of gelatinous alumina in water. A paraffin wax emulsion is prepared by homogenizing molten paraffin wax with a trace of montan wax and a suspension of alumina in water heated to 90C. Hydroxides of magnesium, zinc, chromium and nickel are also mentioned as emulsifying. agents. Reference has been directed by the Comptroller to Specification 359,000.

Abstract: 1,218,017. Photographic colour printing. PAVELLE Ltd. Feb.18, 1969 [Nov.22, 1967], No.53224/67. Heading G2A. In a photographic colour head in or for a photographic printer or enlarger using printing material one of the colour components of which, as described the blue component, has a relatively high speed, and including a photo-electric control means 12 for automatically terminating each exposure (initially taking place simultaneously) when a sufficient exposure, as determined thereby, has taken place, to avoid an unmanageably short exposure time for the blue component, a yellow subtractive filter 7 is partially inserted into the exposing beam 2 from a white light source 1. This blue light is transmitted from only part of the beam area to a light mixing box 4 and then through a diffuser 5 to a transparency 6. The filter 7 is adjustable by manual or photo-electrically controlled automatic control means 8. The control means 12 will, when a sufficient exposure has taken place automatically introduce a shutter 11 into abutment with the filter 7, thereby terminating the exposure of the material to blue light, since the shutter blocks the unfiltered part of the beam 2 containing blue light. The control means 12 will also, when appropriate, introduce additive or subtractive colour filters 9,10 into the whole of the beam 2 to terminate red and green light exposures. In another embodiment Fig.3 (not shown), the part of the beam (2) not passing through the subtractive filter (7) passes through a blue filter (14). In this case the filters (9,10) only overlap the filter (7) when inserted. The invention also includes a method of photographic colour printing of material one colour component of which has a relatively high speed, whereby only part of a white light beam is subtractively filtered to exclude this colour.
