Abstract: 427,520. Colour photography. KODAK, Ltd., Kodak House, Kingsway, London.- (Assignees of Mannes, L. D., and Godowsky, L. ; Kodak Park, Rochester, New York, U.S.A.) Sept. 21, 1933, No. 18936/34. Convention date, Sept. 21, 1932. Divided out of 427,472. [Class 98 (ii)] Refers to the differential colour processing of a plurality of colour-sensitive, silver salt record layers by a method involving colour development of all layers followed by controlled penetration of a bleaching bath, as described in Specification 427,516, and consists in the employment of water-soluble loading agents to extend the time of penetration. Suitable loading agents are watersoluble substances, e.g. sodium sulphate, or organic liquids such as methanol. In an example, a two-layer film is exposed and both layers are colour-developed minus-green, as described in Specification 427,516; the upper layer is then selectively bleached in a chromic acid-bromide bath loaded with methanol followed by a stop bath containing ammonia with or without sulphite, after which the layer is colour - developed minus - red. The invention may be applied to two-colour materials and to the production of master positives as in Specification 427,516. The application of the invention to the threecolour printing material set forth in Specifications 427,517 and 427,519 is also described.

Abstract: 1,179,879. Valves. R. LUDI A.G. 26 April, 1967 [27 April, 1966], No. 19180/67. Heading F2V. The fluid-tightness of two series-connected shut-off valves 13, 14, e.g. in the supply line 10, 11, 12 to a gas burner 15, is tested, e.g. automatically, each time the burner is shut down. An electric signal through a line 37 from the burner to a control 32 shuts the valves electromagnetically. Another signal relayed to a testing device 35 opens a first test valve 25 paralleled across the valve 14 to the atmospheric side 12 to vent the line section 11, an auxiliary manual test valve 26 being open. Valve 25 is re-closed and one minute later a pressure gauge 27 is scanned electrically to indicate whether valve 13 is tight. If not, a warning device (not shown) is operated and prevents re-opening of the valves 13, 14. Otherwise, test valve 21 opens to pressurize the section 11 and is re-closed. After a further minute, the gauge is scanned again for a possible warning should valve 14 not be tight. Valve 26 and a similar test valve 20 are used for manual monitoring.

Filed: 1973-04-24
Abstract: 1370598 Film units POLAROID CORP 24 April 1973 [5 May 1972 6 Nov 1972] 19295/73 Heading G2X In a film unit which includes a layer of photosensitive material between a pair of superposed sheets which is processed in situ by spreading a processing liquid between the sheets, these are spaced apart along the lateral margins by tapered spacers, to assist in obtaining a more uniform spread of the liquid. The unit is of the type in which a supply of processing liquid is provided in a pod attached to one of the sheets, and which is ruptured by passing the unit between pressure rollers which then spread the liquid between the sheets. The liquid tends to vary in thickness from a minimum near the leading edge to a maximum at the trailing edge. By providing a tapered spacer which varies from a maximum at the leading edge to a minimum at the trailing edge, this has a counter action on the varyingthickness of the liquid, so tending to produce a more uniform spread. The tapered spacer is preferably formed as a number of separate layers, as shown in Fig. 6, and is preferably applied to the polyester base sheet 48 by a gravure process. A gravure roller is prepared having cells 66 which vary progressively in depth across the width of the roller. Fig. 7 shows three such rollers, so that three sheets may be made simultaneously. The rollers 62 dip into a supply of coating liquid 70, and the sheet 48 is passed between rollers 62 and a pressure roller 64.

Filed: 1920-07-08
Abstract: 147,602. K÷rting & Mathiesen Akt.- Ges. Dec. 11, 1918, [Convention date]. Induction motor meters; special quaniities, registering.-An induction motor meter for registering the wattless component of the energy supplied has short-circuited rings 2, 3 arranged on the outer limbs of the series core 1 in such a position that their self-induction is increased, and also shortcircuited rings 6, 7 on the central arms of the shunt and series cores 4, 1 respectively. Secondary fields due to currents induced in these rings cause the effective series field to be brought into phase with the effective shunt field or to be displaced by 180 degrees therefrom when the load is non-inductive. The phase displacement of the series field may alternatively be obtained by screening the two arms of the series core by iron sheeting. To register the wattless components due to leading and lagging currents separately, two meters may be employed, each arranged to permit motion in one direction only. Two or more meters may be employed with the usual connexions for polyphase circuits..
