Abstract: 1,053,138. Electric selective signalling. STANDARD TELEPHONES & CABLES Ltd. June 5, 1964 [June 10, 1963], No. 23416/64. Heading G4H. A solid state arrangement for repeatedly generating a fixed message comprises a number of switches which are set according to the dot, dash, and space signals in the transmitted message. The invention is used in a navigation system. Periodically a bi-stable unit gives a start pulse which feeds the first core of a 21-bit shift register. Clock pulses at dot repetition frequency are distributed by the register to 21 switches which are preset and are connected to dot and dash pulse generators or to neither. When a dash is generated the clock pulses are gated from the register to prevent shifting during this signal. The outputs of the dot and dash generators are combined before transmission. In the event of arrival of a start pulse during a shift pulse the start pulse is delayed so that the shift pulse is not obscured.

Abstract: 1,053,798. Indicators. A. E. BATHO. Oct. 5, 1964, No. 40426/64. Heading G5C. In a remote control message display apparatus comprising a display unit (Fig. 1) connected by a cable 52 to a control unit 50 (Fig. 2, not shown) the display unit includes a non-endless band 10 mounted on spindles 12, 14 driven by motors 28, 30. Photo-cells 36 to 46 are positioned adjacent one face of the band to receive light passed through windows 36a to 46a in the band (Fig. 3, not shown) from lamps adjacent the other face of the band. The band is of a transparent or translucent material with the background surrounding the windows, and preferably also the message letters, covered with an opaque coating. The letters themselves may alternatively be picked out in opaque paint or the letters and background may be of contrasting colours. In operation a knob 60 (Figs. 3, 4, not shown) of the unit 50 is turned to select a desired message and a selector button 64 is pressed to pass current via relay 86 to motor 28. Relay 72 is activated to render operable photocells 36 to 46 and when light shines through the window associated with the desired message on to the corresponding photo-cell (37, 38 . . . or 42), that photo-cell closes a stop relay 88 thereby opening the relay 86 and stopping motor 28. A circuit for reversing the band includes a relay 70 the right-hand coil of which is activated when light shines through window 46a on to photo-cell 46 thereby respectively opening and closing the circuits to motors 28 and 30. Impulses from photo-cells 43, 44 trip either one of relays 90, 92 to rotate a " message displayed " indicator drum in the control unit.

Glass fibres are produced by supplying a stream of molten glass 14 to a channel 13 in the upper surface 12 of a body rotating about a vertical axis so that the glass, under the influence of centrifugal force, flows as a sheet on to a rotating radially outer surface 11 of a rotor on which are starting points from which filaments of glass are generated, which filaments are subsequently attenuated into fibres by a gas or steam jet 21. In the embodiment shown, the upper surface is separate from the radial surface and may rotate at a different speed and in the opposite direction thereto. It may, however, be integral with the radial surface (see Figs. 1, 3, 6 and 7, not shown). The starting points may be pyramidal protrusions (Figs. 9 and 10, not shown); " hot spots " formed by blind bores in the outer or inner radial surface, in which case a heating fluid is supplied to the inside of the rotor (Figs. 11 and 12, not shown); or apertures (Fig. 8, not shown) through which air may pass from the (pressurized) interior of the rotor. The rotor may be surrounded by an induction heater (39 in Figs. 3, 6 and 7, not shown) and the glass filaments may be subjected to one or more directing and attenuating jets as well as a " soft " flame from an annular duct (42 in Fig. 7) after leaving the rotor.
