Title: Loading box for loading a length of film into a processing installation
IPC: G03B17/26
Filed: 1977-01-05
Abstract: 1516814 Film dispenser WAINCO PRODUCTS Ltd 5 Jan 1977 [5 Jan 1976] 00133/76 Heading B8M A box whereby a length of sensitized film is fed or loaded into a (photographic) processing installation comprises a rolled film storage chamber, an aperture through which an end of the film passes so that an end portion is outside the chamber (without admitting light thereto) and a track on which, in use, lies the end portion but with at least part of its edge region not bearing against the track, e.g. the track is partially cut-away for such purpose, so that the end portion may be gripped: the aperture may be spring-biased into a normally closed position. The leading-box may be combined with a releasably attached device whereby film is fed into the box from a resiliently mounted, wound spool prior to normal separate use of the box in the installation. A locating tongue on the device enters a slot in the box and actuates a slidable plate to open the aperture in the box (to allow film to be fed therethrough) as the device and box are combined, and the film is secured by a manually operable cutter when a required length has been coiled in the box. The film may be fed into the box by pulling on (and so separating therefrom) a backing strip, or by means of a toothed driving wheel the teeth of which engage perforations in the film.

Title: Improvements relating to control and protection equipment for sectionalised electricsupply systems
IPC: H02H7/26
Filed: 1937-01-02
Abstract: 486,323. Protective cut-out arrangements. GRIMSDALE, A. E. K.O., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Jan. 2, 1937, No. 136. [Class 38 (v)] Control equipment for a sectionalized supply system, such as a traction system employing regenerative braking, comprises a contactor or contactors connecting one or both corresponding lines of a pair of adjacent separately-fed. sections, and controlled directly or indirectly by a pair of control coils which are energized respectively in accordance with the voltages of the two sections and so arranged that both coils must be energized by the normal sectionvoltage to effect and maintain closure of the contactor. Overload means responsive to linecurrent between the sections when the contactor is closed, is arranged to break the energizing circuit through one or both control coils when the current exceeds a given value. The + and - lines of sections A, B of, for example, a trolley bus system are adapted to be interconnected by contactors S, S<1> having operating half-coils a, b and a<1>, b<1> respectively, such that both half-coils of each contactor form control coils and must be energized to effect or maintain closure of the contactor. The half-coils a, a<1> are energized from section A over normallyclosed contacts of overload relays R, R<1>, and over an interlock contact of an isolator Ia, and similarly b, b<1> are energized from section B over contacts of R, R<1> and an interlock contact of isolator Ib<1>, these isolators, together with additional ones Ib, Ia<1>, being simultaneously operable and, when open, preventing energization of the contactor-operating coils. Relays R, R<1> open with a time-delay at a currentvalue which is less than that of the substationbreaker, and when they operate, the contactors are opened and will not reclose until full voltage has been restored on each section A, B. In a modification, Fig. 2, each contactor has a single operating coil c, c<1> and the two coils are connected in series across section A over the contacts of a relay D energized by section B, or over contacts of two relays, one across each section. The apparatus may be incorporated as a unit in the base of the trolley-wire standard. The Provisional Specification states also that the interlock contacts of the isolators should open before the main contacts, so as to prevent the main circuit being opened at the latter.

Abstract: 609,506. Resistance measurements; thermionic valve ammeters and voltmeters. SANGAMO WESTON, Ltd. Jan. 3, 1946, No. 291. Convention date, Feb. 10, 1945. [Class 37] In a megohmmeter of the thermionic valve type a cathode resistance R2 is regulated such that the cathode current flowing through a meter 5 is 100 microamperes with zero resistance across the test terminals 6, 6<1> connected respectively to the anode P and grid G of a high-mu triode 1. On applying the unknown resistance between the test terminals 6, 6<1> (as shown, the insulation resistance separating cable conductors 8, 8), the potential of the grid G is reduced and the cathode current drops to a value in direct proportion to the unknown resistance. The scale, Fig. 2 (not shown), of the meter 5 is graduated logarithmically in megohms. To compensate for the residual anode current at " infinity " a fixed or variable resistance R3 is connected across the meter 5 and cathode heater battery 3. The circuit may may include a grid resistor R4.
