Abstract: It is known to supply solution to a process and to collect effluent therefrom using `bag-in-box` arrangement each having a predetermined volume. However, if the process must be supplied with greater volumes of solution, the use of larger `bag-in-box` arrangements is limited by weight restrictions that an operator can handle. Described herein is a method of using a number of `bag-in-box` arrangements coupled together to provide a larger volume of replenisher solution to a process and to collect of effluent therefrom than would be the case if only a single `bag-in-box` arrangement is used. An automatic changeover system can be utilised which allows the process to be supplied with a greater volume of solution than that which corresponds to the legal weight limit without having to empty the supply `bag-in-box` arrangements into a large replenisher tank.

Abstract: Described herein is an alarm system for use with a `bag-in-box` arrangement (10) which is used to collect effluent from a processing apparatus (20). The alarm system comprises a chamber (50) located between the processing apparatus (20) and the `bag-in-box` arrangement (10) which includes a level sensor (52) which indicates that the `bag-in-box` arrangement (10) has been overfilled by a predetermined amount and is ready for changing.

Abstract: Used single use camera bodies (10) and miscellaneous loose parts (130, 132, 134) are dumped into a receiver conveyor (72) from which they move to a metering conveyor (88) which delivers them to a series of vibratory grid separators (106, 108, 110) having grid bars (124) separated by slots (126) configured such that each camera body can be positioned with at least one lengthwise corner (148-154) located in the slot and the center of gravity (156) of the camera body positioned above the slot. Camera bodies are thus conveyed lengthwise along the vibratory grid separators to enable loose parts to fall more readily through the slots. Camera bodies are then separated by types at a plurality of sorting stations (186).

Abstract: A camera metering mechanism discriminates between 1) adjacent perforations in a set, which trigger said metering mechanism to interrupt the film advance, and 2) adjacent perforations between sets, which do not trigger the interruption. The mechanism uses a difference in spacing between the perforations, which alternates between a first distance within a set and a second longer distance between sets. The mechanism is triggered to interrupt film advance when the space between detected perforations is less than a predetermined distance. If the space exceeds the predetermined distance, then film advance continues until the next successive perforation. According to more specific features, the perforation detector initiates electrical transitions at the leading and trailing edges of the perforations, and film distances are a determined from the time difference between selected transitions.

Abstract: A method for forming a film scroll and assembling the film scroll into a non-lighttight camera body begins in a darkroom by winding a filmstrip into a film feed roll from a filmstrip source, such as a stockroll onto a winding quill after attaching a formed leading portion thereto. According to the present invention, an outer end of the film feed roll is attached to a film spool of a film cartridge to form a prewound scroll and cartridge assembly for loading into respective chambers of the non-lighttight camera body section. A cover is then fixed to the camera body section to make the camera lighttight.

Abstract: A photographic camera (10) includes a film supply chamber (14); a film takeup chamber (16) and a film exposure gate (18) positioned between the chambers. The gate defines a maximum exposed image width (W) in a direction of film travel between the chambers and a maximum exposed image height (H) in a direction transverse to the direction of film travel. A plurality of mask members (24, 26) extend transverse to the direction of travel, each mask member being configured for masking only a portion of the maximum exposed image width. There is no mask in the camera configured for masking a portion of the maximum exposed image height. A mechanism (88-94) moves the mask members toward or away from a center of the exposure gate to reduce or increase only a final exposed image width (W.sub.e), without masking the maximum exposed image height. As a result, the final width of the exposed image indicates a required enlargement of exposed image to produce a pseudo telephoto print.
