(3) Special film developing tanks. These may be of metal, plastics, stoneware, etc.; they enerally incorporate devices such as supporting rods, baskets for removing the films From the bath. Certain developing tanks are also used for rinsing, fixing and washing films. (C) S ecial trays (of lastics, stainless steel, enamelled sheet iron, etc.), clearly intended for !oto aphc use, %ut not including articles which may also be used for other purposes re.g., E r general purpose laboratory or hospital use). @) Tanks for washing negatives, including rotary washing apparatus. (E) Print driers, glazers and drier-glazers (single face, double face, rotary drying machines hand-operated, etc.); roller squeegees; polished stainless stee platesetc.); and chrormum-plated p ates clearly designed to be fitted to these articles or used separately. r rpes9 (F) Printing frames, including vacuum rintin frames, (of metal or of metal and wood) for contact printing; printiog machines Eor proFessional or amateur photographers, etc.); and illuminated frames, without a developer, for making exposures only. (G) Film cutting machines and apparatus, of a kind used in photographic (including cinematographic) laboratories. (H) Special holding frames for retouching negatives. (W) Dry-mounting presses for photographic use. (K) Specialised machines and apparatus used in cinematographic laboratories, such as : (1) Film developing machines whether or not automatic. (2) Film slitting or cutting machines (e.g., for cutting 35 mrn film into two 16 mrn films). (3) Printin machines and cinematographic reducers and enlargers (optical printer!$. (4) Optical effects machines. (5) Sound control units for editing and synchronising sound films. (6) Recording apparatus which reproduces on a paper stri a " slowed down " and enlarged image of the sound track on a film, for use in syncI? ronising and dubbing. (7) Film cleaning machines; machines for treating worn negatives before reprinting; combined cleaning and treatment machines; machines for cleaning negatives. (8) Waxing machines for de ositing a thin coat of wax on both edges of the emulsion-coated side of the ilrn. (9) Joiners (splicers) (hand- or pedal-operated, etc.). F (10) Film editing units. These may be fitted with a picture-head and a sound-head. Such apparatus may be used, for example, to synchronise images with a sound track. Separately presented ictute-heads, and devices equipped with sound-heads which are used together wit frame viewers on synchronisation tables, also fall in this heading. However, separately presented sound-heads are excluded (heading 85.22). (1 1) Machines for numbering copies of films by perforation. (12) Editing desks for handling films; these are fitted with s 001rewinders. Special fdlm re-winders for winding negatives (e.g., after printing); ilm measurers and footage counters, to check the len of films (separately presented counter mechanisms are excluded, see heading 90. 9). !P P (1 3) Film titling apparatus. (14) F i viewers for editing rinted cinematographic film.These viewers may be combined with sound recorEng or reproducing apparatus! (I,) Film viewers for still images used to examine photographic negatives in photographic laboratories. a (w sp ecialised equi ment used in reproduction work (not being photoc ying a aratus By the o heading 84. 3), e.g., apparatus for developing specially sensitise" paper ammonia vapour process. (11) NEGATOSCOPES Negatoscopas are used mainly for examining medical radiographs or radiophotographs. They may be of ve different types, ranging fkom wall-mounted light boxes to automatic magazine-fed ra%ograPh viewers, (111) PROJECTION SCREENS These screens are used in cinemas, schools, lecture rooms, etc. They include projection screens for three-dimensional presentation; also portable screens, rolled in sheaths or contained in boxes, for mounting on tripods, on tables, or for hanging from the ceiling. They are often made of a fabric coated white, silver or with lass grains (microspheres), or of sheets of lastics; these fabrics or sheets are generally per orated. To fall in this heading, however, g e y must be elearly identifiable (e.g., by means of hems or rims, eyelet-holes). f PARTS AND ACCESSORIES Subject to the provisions of Notes 1 and 2 to this Chapter (see the General Explanatory Note), parts and accessories identifiable as being solely or pmcipally for use with the apparatus and equipment of this heading also fall here. This heading also excludes : (a) Photographic (including cinematographic) studio equipment, such as lighting app.aratus, reflectors, spotlights, electric lighhng lamps and tubes of all kinds, sound effect equpment, mcrophone booms, scenery, etc.; these fall in their respective headings. (b) Haleone or similar printing screens (headings 37.05,90.01,90.02, etc. as the case may be). (c) Paper or paperboard cutting machines of all kinds (heading 84.41). (d) Apparatus for the projection or drawing of circuit patterns on sensitized semiconductor materials (heading 84.86). (e) Loudspeakers, microphones and audio-frequency electric am lifiers, other than those presented with and forming an integral part of any of the instruments of this teading (heading 85.18). (f) Cameras for recording documents on microfilm, microfiche or other microforms (heading 90.06). (g) X-ray fluorescent and intensifying screens (heading 90.22). (h) Ex osure calculating discs and rulers heading 90.17); exposure meters, photometers, densitometers, co our temperature meters (heading 9 .27). P (ij) Hand-operated stamps for numbering prints (heading 96.11).
