Abstract: A control valve arrangement implementing the use of pneumatic valves to control air flow for textile machinery blowdown, and the remote control of such pneumatic valves by means of remotely located solenoid valves. In air flow systems employing pneumatic valves of the type having a constrictable flexible annulus arranged within a rigid conduit with air under pressure selectively admissible to a space between the annulus and the surrounding conduit wall so as to effect constriction of the annulus to close off the passage through the conduit, solenoid actuated control valves have conventionally been employed to control the flow of fluid to said space between annulus and conduit to effect annulus constriction. Where these solenoid actuated control valves are located at control points which are remote from the pneumatic valve, it is found that the release of the annulus constricting air pressure is delayed due to the time delay between solenoid actuation and pressure change at the remote pneumatic valve.

Abstract: Apparatus is disclosed for utilizing a low energy electron beam to permit monitoring the rate of deposition and composition of the evaporant particles in a vacuum deposition system. This is accomplished by passing a sample of the evaporant employed in the vacuum deposition process through an enclosure defining a flow path for the evaporant sample which crosses the path of a relatively low energy electron beam which is sufficient to excite the electrons of the atoms constituting the vaporized particles in the deposition chamber. The outer-shell electrons of the atoms constituting the evaporant, after excitation, drop back to a lower energy state in the course of which photons are released which are characteristic of given materials. The enclosure is formed with an optical opening receiving the photons in a path orthogonal with respect to the excitation beam and evaporant sample path, and a photodetector is optically coupled to the opening for sensing the emitted photons.

Abstract: Cricothyrotomy apparatus for establishing an emergency breathing path for patients experiencing upper respiratory obstruction. The apparatus here provided enables the user to perform the necessary operative steps on a patient in a relatively automatic and hidden fashion, so that the user is not aware of the fact that he is piercing the patient's throat and inserting a tube therein. This is accomplished by providing a housing enclosing a spring pressed surgical blade and spring pressed tube or according to a second embodiment, a combined spring pressed tube and blade. A release mechanism actuated by a simple pressure button on the exterior of the housing releases the knife and tube (or tube with piercing blade) for automatic positioning at the desired point in the throat of the patient. A location marker is further provided to insure desired positioning of the cut and tube on the patient.

Abstract: A method for regulating the operation of yarn clearers having error correcting means such as yarn cutters, and sensing means providing an electrical signal representative of the controlled quality. The method comprises the steps of: feeding the signal from the sensing means to two independent electrical circuit channels each having separate threshold switch means, the threshold switch means of one circuit responsive to signals corresponding to yarn faults of given magnitude. The threshold switch means of the other circuit responds to signals corresponding to faults of given duration. Thereafter, an independent control signal is obtained from each of said channels for initiating the operation of the cutters when a limiting value selected for each of said two channels is exceeded.

Abstract: A breathable flame resistant fabric construction having a pile surface providing desired hand and dyeability, along with the porosity necessary to provide breathability. The fabric construction is formed by bonding flock fibers to the surface of a fiberglass base fabric by means of a polymeric adhesive which in the presence of heat will release flame quenching gases, blocking the flow of oxygen to the normally flammable flock fibers. It has been found that if the base fabric is first coated with a plasticizer before applying the polymeric adhesive, such as employed to secure the flock fibers to the fiberglass, the subsequently applied adhesive will coat the fiberglass yarns constituting the fabric without producing an adhesive film extending over the spaces between yarns, leaving air passing interstices in the fiberglass base fabric, and additionally improve the hand of the base fabric by providing for an increase in "elastic slippage" (i.e.
