Title: Improvements in or relating to digital instruments
Inventor: CLEMENTS JOHN ANTONY
IPC: G01P3/48
Filed: 1967-10-16
Abstract: 1,248,904. Digital display arrangements. SMITHS INDUSTRIES Ltd. 16 Oct., 1968 [16 Oct., 1967], No. 47085/67. Heading G4H. The output of a measuring device is applied to a number of digital display devices 30-32, having an astable oscillator within unit 10 arranged to switch the display devices on and off at such a rate as to be undiscernable to the eye and means are provided for varying the mark/space ratio of the oscillator to vary the brightness of the display. The anodes of the display devices are connected to the 200v. supply through resistors 34 and via diodes 35 to the multivibrator. When the multivibrator is in one state it acts as a short circuit across the display devices to extinguish them. The mark/space ratio is variable by an adjustable potentiometer 37. The cathodes of the displace devices are connected to a speed measuring circuit for a road vehicle. In one form a generator driven from the output shaft of the gear-box generates a frequency signal which is squared to produce pulses at a frequency indicating the speed. A sampling gate opened for a set period passes the pulses to a three decade binary counter providing signals for the display device. In another form hold circuits are interposed between the counter and the display to hold the signals during the sampling period. In a modification of this form the sampling gate is omitted, the sampling period being established by resetting the counters at the start and, at the end of the period enabling the hold circuits to store the value counted. In a variant of this form the timing circuit may be triggered by a gate detecting a zero condition in the counter, which counts continuously, the gate enabling the hold circuits after the elapsed sampling period. An independent timing circuit resets the hold circuits to zero if the interval between two successive enabling pulses exceeds a set value. In another form the frequency signal is converted to an amplitude signal and compared with a step signal to obtain a timed pulse. This is used to close a gate which, since the beginning of the cycle, has been passing clock pulses to the counter.

[Also in Divisions E1 and F2] A valve for use as an odour seal in a waste pipe has a housing 15, Fig. 1, an outlet 16, and a diaphragm 21 normally pressed by a weight 22 against the outlet and arranged to be lifted when the pressure of the liquid surrounding the outlet exceeds a predetermined value. The housing 15 is connected by a pipe 18 with the sludge trap 11 of a wash stand 10 and has a cover 19 with a small hole 23 and a larger hole 24 closed by a rubber disc 25 so that the diaphragm 21 may open more quickly than it closes. In a modification, the sludge trap is dispensed with and the supper edge of the outlet provided with a small notch whereby water surrounding the outlet may form a seal without normally contacting the underside of the diaphragm. In Fig. 3, a diaphragm 44 loaded by a weight 45 controls an outlet 33 in a bath waste pipe 36 and is carried by a cover 41 provided with a vent 47, 48. A floor drain 31 forms a cover to a bowl 30 containing a rubber valve 51 which engages concentric ribs 52, 53, 54 preventing further inflow from the drain if the level in the bowl becomes excessive, the rib 52 being engaged first and the vent 47 being closed by a stud 46 on the diaphragm to avoid the risk of water entering the space between the diaphragm and its cover. The vents 47, 48 may be replaced by a vent in the stud 46.

Four article-forming cavities are spaced around a central pouring/feeder/sprue 10. To cast directionally solidified articles e.g. turbine blades the mould is placed on a powdered Al 2 O 3  base 44 within the susceptor 46 of an induction furnace having vertically spaced separately power-supplied induction coils 48, 49 and the mould is preheated above the melting point of the metal to be cast. Molten metal is poured into the feeder/sprue 10 to fill the cavities and downward solidification is commenced from the chill plate by progressively turning off the induction coils in a downward direction. The alloy in the feeder/sprue 10 is kept molten by resistance heaters 50. When casting single crystal articles a solidification starting portion 34 is provided with a spiral passage 32 to select a single grain. For the casting of columnar grained articles the spiral passage is omitted. The entire casting assembly is contained within a vacuum chamber for vacuum or inert atmosphere casting.
