Title: Induction terminal unit for air-conditioning systems
IPC: F24F1/01
Filed: 1972-06-28
Abstract: 1381405 Air-conditioning FLUIDTECH CORP 28 June 1972 [1 July 1971] 30331/72 Heading F4V In an air-conditioning system air is supplied to each of a number of zones through an induction terminal unit, Fig. 3, having two plenum chambers 11 and 12, ambient air being drawn into plenum 11 through heat-exchange coil 24 by air under pressure issuing from jets lie and ambient air being drawn into plenum 12 by air from jets 12c to by-pass the conditioning plenum 11. A fluidic control system operating in response to the temperature in the zone to be conditioned switches the air under pressure to duct 11d or duct 12d according to whether the air passing to the zone needs to be conditioned or not. The heat exchanger may heat or cool the air drawn through it. Air drawn into the by-pass plenum passes below the heat exchanger and is not heated or cooled. Air from the plenums passes into the zone via grills 11e, 12e. The fluidic control device, Fig. 4, may consist of a thermostat 26 designed to operate one or the other of a pair of solenoids 27a, 27b, controlling a bi-stable fluid amplifier 25. This consists of an inlet 22 for the air under pressure and outlets 25b, 25c. The solenoids control the flow of air in control channels 25d, 25e to direct the air from inlet 22 to outlet 25b or 25c. In another form (Fig. 5, not shown), a bi-stable fluidic device is used of the kind in which each outlet channel contains a Pitot tube, the pressure in the channel carrying the air stream being applied to switch some of the air under pressure to a control jet maintaining the flow in that channel. The Pitot tubes are also connected to a thermally operated valve adapted to close or vent the control line so that at a given temperature the bi-stable device is switched to the other condition. Air is therefore passed alternatively through the coil plenum and the by-pass plenum cyclically to keep the temperature in the zone at the desired level. Separate plenums may be used for heating and cooling (Fig. 6, not shown), a tri-stable control device being used to select the plenums.

Third harmonic playback distortion is reduced when cutting gramophone records by applying a compensating signal to the cutting head. Each component signal of a binaural recording is treated in such manner to derive a compensating signal. For each channel the compensating signal is obtained by first applying the input signal to two stages 34 and 35 in parallel. Stage 34 has a characteristic y = x<SP>3</SP> and converts a signal a sin wt into ¥ a<SP>3</SP> sin wt -  a<SP>3</SP> sin wt and stage 35 converts signal a sin wt into a<SP>3</SP> sin wt (or  a<SP>3</SP> sin wt - a<SP>3</SP> sin 3 wt). The output signals from stages 34, 35 are then combined to produce an output signal a<SP>3</SP> sin 3 wt. This signal is passed in succession through two differentiating networks 36, 37, each comprising a capacitor and shunt resistor, to produce a signal of appropriate phase and proportional to the square of the frequency of the input signal. A voltage divider 38 is provided, the resistance of which varies according to the inverse of the fourth power and movement of the tap of this divider 38 is controlled by a drive 22 controlled by the speed of the groove carrier in relation to the cutting stylus. By the voltage divider 38 the doubly differentiated signal is multiplied by the reciprocal value of the fourth power of the groove speed. An output regulator 39 takes into account a constant part of the compensation signal which depends on the square of the radius of a standard pick-up stylus. The cutting stylus is of non-circular cross-section.
