Abstract: 546,592. Phonographs. RADIO CORPORATION OF AMERICA. Oct. 31, 1940, No. 16937. Convention date, Oct. 31, 1939. [Class 40 (ii)] A mechanism is actuated step by step by the movements of a pick-up arm to interpose a stop member in the path of a brake actuating member after a given number of playings, whereby the player is made aware that replacement of needle is needed. In the form shown in Figs. 1 and 2, every time the pick-up 11 is replaced on a rest 15, this rest is depressed against a spring 21, and a finger 17a on the rest turns a ratchet wheel 29 one step. After the predetermined number of steps, the end 31b of a lever 31, urged by a spring 35 into engagement with the ratchet wheel, falls in a deep notch 29a in the ratchet wheel; and a post 7 is thereby lifted through a hole in the motor board 1 into the path of the usual brake lever 5. In a modification, Figs. 3 and 4 (not shown) the outward swing of the pick-up arm transmits rotation through a ratchet device to a gear wheel, which rotates another gear wheel fast with the ratchet wheel controlling the lever 31. The post 7 may also be arranged to strike a bell, or to control a switch in the circuit of a driving motor. Specification 460,897 is referred to. The Specification as open to inspection under Sect. 91 describes also an arrangement in which the ratchet wheel 29 after the given number of steps closes contacts in the circuit of an electromagnet, the armature of which then releases a signal flap ; or the contacts cause a driving motor or an amplifier to be switched off. This subject-matter does not appear in the Specification as accepted.

Colour photography ; plates and films.-A plate of the kind comprising three superimposed, separable layers each sensitized for a different part of the spectrum, and upon which the three partial colour images are produced simultaneously by a single exposure, consists of three elements a, b, c each comprising a cellulose, muscovite or like support carrying an emulsion laver, and independent, interposed filter screens d, e, all of which are superimposed on a common support k, and forced into optical contact by evacuating the air between them and applying an edge-seal. In the form shown the layer f<1> is sensitized for blue-violet by treatment with chinoline dye, which also greatly increases the sensitiveness of the layer; the layer f<2> is sensitized for red with pinacyanol, dicyanin, abney resin, &c. ; and the layer f<3> is sensitized for green with pinachrome, erythrosin, &c. The filter screens d, e, are of gelatine dyed respectively orange and green, and are provided on both faces with continuous marginal strips r of guttapercha or other adhesive material. The support k is of black cardboard carrying a similar marginal strip r. The air between the elements is evacuated, as by placing the plate upon a support, covering it with a celluloid sheet which is caused to adhere at its edges to the support, and exhausting the space so enclosed. At the same time the adhesive strips r are heated, for example, electrically, to cause them to effect an air-tight closure. The edges of the plate are finally coated with celluloid or any colloidal protective coating m. The seal m may be, employed alone. Before development, registration holes are punched at opposite sides of the plate, close to the edges, and the elements are separated after cutting off the margins of the remaining two sides.
