Abstract
Abstract The present invention provides an air breather annunciator for supplying and regulating a source of air to a remote operational station to be employed by, for example, a sand blaster working within a polluted air environment. The device basically comprises an air storage capacitor operably connected to an air supply and which in turn feeds a source of air through output regulator to an operational station requiring a source of air. Alarm means is provided for the visual and audio indication of either low pressure air supply or interruption thereof. Alarm circuit check means are also provided for manually checking both the visual and audio alarm circuits.

Claim 1
Independent Claim
209 words
Air breather annuniciator means comprising: a. air storage capacitor means adapted for being operably connected to a source of supply air; b. air output regulator means connected in series with said air storage capacitor means for regulating the pressure of air supplied from said air storage capacitor means to an air demand operational station means; c. first conduit means operably connecting said air storage capacitor means with said air output regulator means; d. said air demand operational station means adapted for being operably connected to equipment requiring a source of pressure regulated air for life support; e. second conduit means operably connecting said air output regulator means with said air demand operational station means; f. annunciator means comprising alarm circuit means connected in parallel with said air demand station means at least across said air storage capacitor means for indicating an interruption of air flow to said air storage capacitor means, said alarm circuit means being further defined as comprising pressure sensing means for pneumatically sensing pressure variation and selectively actuated alarm means for indicating pressure changes from a predetermined set point as indicated by said pressure sensing means; and g. third conduit means operably connecting said alarm circuit means across the output of said air storage capacitor means.
Claim 2
Dependent Claim
209 words
Air breather annuniciator means comprising: a. air storage capacitor means adapted for being operably connected to a source of supply air; b. air output regulator means connected in series with said air storage capacitor means for regulating the pressure of air supplied from said air storage capacitor means to an air demand operational station means; c. first conduit means operably connecting said air storage capacitor means with said air output regulator means; d. said air demand operational station means adapted for being operably connected to equipment requiring a source of pressure regulated air for life support; e. second conduit means operably connecting said air output regulator means with said air demand operational station means; f. annunciator means comprising alarm circuit means connected in parallel with said air demand station means at least across said air storage capacitor means for indicating an interruption of air flow to said air storage capacitor means, said alarm circuit means being further defined as comprising pressure sensing means for pneumatically sensing pressure variation and selectively actuated alarm means for indicating pressure changes from a predetermined set point as indicated by said pressure sensing means; and g. third conduit means operably connecting said alarm circuit means across the output of said air storage capacitor means.
Claim 3
Dependent Claim
65 words
The air breather annunciator means of claim 1 further characterized in that said alarm circuit means further comprises: annunciator valve means operably connected and paralleled across said capacitor means, said annunciator valve means being further defined in that upon an interruption of air flow to said air storage capacitor means, means in said annunciator means repositions whereby said alarm circuit means actuates said alarm means.
Claim 4
Dependent Claim
62 words
The air breather annunciator means of claim 2 further characterized in that said annunciator valve means is further defined as comprising: a third input regulator sensor means operably connected in series with said third conduit means for actuating said annunciator valve means; and alarm circuit input regulator means operably connected in series with said annunciator valve means for actuating said alarm circuit.
Claim 5
Dependent Claim
22 words
The air breather annunciator means of claim 3 wherein said alarm means is further defined as comprising audio and visual alarm means.
Claim 6
Dependent Claim
49 words
The air breather annunciator means of claim 4 further characterized as comprising: output/supply pressure gauge means operably connected in parallel across said capacitor and said output regulator means for selectively indicating the pressure level of the air supply source or the output pressure level of said output regulator means.
Claim 7
Dependent Claim
66 words
The air breather annunciator means of claim 5 further characterized in that said alarm circuit means further comprises: an alarm test circuit further defined as including alarm test switch means operably connected to an air input to said annunciator valve means and to said audio alarm means whereby said annunciator valve means can be by-passed and said audio alarm means individually checked for its proper operation.
Claim 8
Dependent Claim
98 words
The air breather annunciator means of claim 6 further characterized in that said annunciator valve means is further defined as comprising: a self-contained annunciator circuit capable of monitoring at least one pneumatic signal which represents a multitude of process variables, said valve being provided with a selection of outputs for announcing the state of the monitored signal, said outputs indicating signal present, signal absent, and signal absent but acknowledged, said audio alarm means being operably connected to said signal absent output such that when said signal absent output is acknowledged manually, said audio alarm output is thereby removed.
