Title: Improvements in and relating to photo-electric relay systems
IPC: G06M7/04
Filed: 1935-10-17
Abstract: 450,287. Controlling apparatus by light. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London. Oct. 17, 1935, No. 28721. Convention date, Oct. 17, 1934. [Class 40 (v)] A relay is operated when a cell is illuminated by the main beam and an auxiliary beam which is controlled by the main beam falling on the cell. Where the relay is to be operated on the illumination of the cell, the main beam falling on the cell 2, Fig. 6, produces corresponding current in the valve 4 which is sufficient to ignite the lamp 5 but insufficient to actuate the relay 7. The auxiliary beam from lamp 5 falls on the cell 2 so that the current through the valve 4 increases to actuate the relay 7 which opens contacts 7<1> de-energizing the lamp 5 and closes contacts 7<11> actuating a counter 8. The cell is thus unilluminated, the main beam having passed off, and the relay is de-energized to prepare the circuit for the next illumination of the cell. Where the relay is to be operated by an occultation of the main beam, the cell 2, Fig. 7, is normally illuminated by both the main beam and the auxiliary beam from lamp 5 and the relay is actuated to open contacts 7<1>, 7<11>. When an occultation of the main beam occurs, the current through the valve 4 is insufficient to maintain the ignition of the lamp 5 and the actuation of the relav 7. The auxiliary beam disappears and the main beam when it re-appears is insufficient to maintain the relay 7 actuated, so that the relay is deenergized to close contacts 7<1> and re-ignite the lamp 5 and close contacts 7<11> to actuate the recorder. The relay cannot be energized over contact 7<1> because of the rectifier 14. The cell is now illuminated by both the main and auxiliary beams so that relay 7 is actuated and the circuit prepared for the next interruption of the main beam. The circuits are stated to be operable by extremely short illuminations or occultations of the cell. Where it is desired to record only illuminations or interruptions longer than a predetermined minimum, the lamps 5 are replaced by filament lamps whose light will only appear or disappear after a predetermined duration or interruption of current.

Title: Method of making crinkled artificial fibres
Inventor: ABERNETLY NELSON WORDEN
IPC: D01D5/22
Filed: 1950-11-24
Abstract: <PICT:0695033/IV (a)/1> Crinkled artificial filaments are produced by melt-spinning fine filaments of an extrudable organic thermoplastic material downwardly through air and directing against all sides of each such filament a plurality of streams of a gas inert to and cooler than the filaments, which streams converge upwardly to define a cone with its apex 1-10 inches below the extrusion orifice, and cooling and stretching the filaments.  As shown, the material, which may be a polymeric or co-polymeric composition of vinylidene chloride, is extruded from the orifices of a conventional plastics extruder to form one or a plurality of filaments 10 which pass downwardly, while still hot, through a zone surrounded by gas nozzles 12 in a tubular ring 19.  The nozzles 12 are directed toward the filaments and tilted slightly upwards so that streams of air or gas converge in an "air cone" with its apex in the axis of the bundle of filaments 10 slightly above the plane of the nozzles 12, as shown by broken lines.  The ring 19 is disposed concentric with and in a horizontal plane at right angles to the axis of the bundle of filaments 10, and its distance below the extrusion orifice is adjustable.  After their passage through the air streams the filaments are further cooled by passing them by means of guide rolls through a bath of cold water or other inert liquid and are cold-stretched by means of snubbing rolls up to about 400 per cent before they are wound on a storage reel.  The crinkled filaments produced are more uniform than those produced by blowing a gas or spraying a non-solvent liquid on but one side of the filaments. U.S.A. Specification 2,377,810 is referred to.
