Abstract: An anesthesia machine includes a breathing system for delivering a gas mixture, including an anesthetic gas, to a patient for inhalation and for collecting exhaled gas from the patient. A cannister flow communicates with the breathing system and removes carbon dioxide from the exhaled gas. A pressure relief valve includes a housing that defines a chamber in flow communication with the breathing system, a valve member for regulating a flow of gas from the breathing system into the chamber and venting gas into the chamber when pressure in the breathing system exceeds a pressure threshold setting, and a plunger for preventing the flow of gas into the chamber independent of the pressure in the breathing system without changing the pressure threshold setting. The cannister, pressure relief valve, and other components are secured to a manifold having internal flow channels.

Abstract: A face mask for filtering airborne particles formed by an upper portion adapted for placement over a user's nasal area and a lower portion adapted for placement over a user's oral area. Ribs are formed ultrasonically extending along the length of the upper portion, and a pair of ears are formed at either end having openings therethrough to receive a plastic strap for passing through the openings of the ears to secure the mask to a user's face. The mask is formed by layers of plastic material including scrim and filtration material forming the upper and lower portions that have been ultrasonically bonded together. A process for making the mask includes providing plastic fabric layered materials that are ultrasonically welded with a plurality of ribs and slitting and sealing them to form two portions. The two portions are fed in overlying sandwiched relationship to each other and scored for the ears while at the same time welding them together to form an upper and lower portion of the mask.

Abstract: A gas regulating valve, especially for use in breathing valves for diver masks and the like. The valve comprises a sleeve-shaped housing (1) having an inlet chamber (I) and an outlet chamber (II), a main valve body (2) cooperating with a seat (3) separating the inlet chamber (I) from the outlet chamber (II), a piston (12) or the like separating the outlet chamber (II) from a servo chamber (III), and a control valve (5,6) arranged to be opened and closed by the main valve body (2). The control valve (5,6) causes a controlled gas flow to the servo chamber (III), which entails that the main valve body (II) is forced to move such that the seat (6) of the control valve at all times rests sealingly against the valve body (5) of the control valve.

Abstract: A second stage breathing regulator especially suited for use in scuba diving comprises an automatically adjustable air flow deflector or vane to redirect a portion of inlet high velocity air of a venturi-initiated vacuum assist-type regulator configuration. At greater depths the flow vane increasingly interrupts and redirects a selected portion of the air stream to increase the venturi effect. As a result, the diver's inhalation effort requirements can be relatively constant throughout the breathing cycle at any depth or can be tailored to a desired non-constant profile as a function of depth. A piston responsive to ambient water pressure by extension proportional to depth, places the flow vane to increasingly redirect the air flow at greater depths thereby increasing the venturi effect. The diver is thus freed of having to make manual adjustments to the second stage under water.

Abstract: A radio paging receiver enables an user of the receiver later to see a received message even when an alert stopping operation or message confirmation operation is first executed in an environment too dark to see the received message. The receiver has a photosensor for detecting whether a display environment is light or dark. If the alert stopping operation is executed in the dark condition, the received message is stored in a memory as an unconfirmed message, so that the user later can see and read the received message in a light condition after a change of the environment. In addition, when the environment is changed from a dark condition to a light condition, if an unconfirmed message exists in the memory, the receiver alerts the user.

Abstract: A process for operating a remote-controllable central locking installation of a vehicle by means of a transmitter, which can transmit coded signals--for example acoustically by means of ultrasound, optically by means of IR and/or by means of USW high-frequency waves--to a receiver fitted in or on the vehicle. An initialization is typically carried out before the actuation for the first time of the central locking installation, or a reinitialization is carried out before the next actuation of the same, to cancel the previous code, that is the code which can be used in future, or in the case of a changing code the relevant code set which can be used in future, being fixed for the first time or once again by the receiver being driven, for example by means of a special control code, into a state in which it can be (re)initialized. The receiver indicates that the receiver is ready for (re)initialization and/or after successful (re)initialization by means of an activation of the door locks.

Abstract: A local call receiver or pager includes a circuit (3) for receiving and demodulating a call signal emitted by a central station and which contains synchronization code words, address code words and message code words. The circuit is connected to the pager energy source (16) through a switching circuit (3b) for cutting off the energy supply when it is not necessary to receive the call signal. The pager also includes a decoder (4) intended to control the switching circuit as a function of the analysis of the call signal synchronization code words. The analysis is effected bit-by-bit and the receiver circuit is disconnected as soon as the synchronization code word is recognized, in most cases following analysis of only a few bits of the code word. Application is in respect of pagers in which a satisfactory compromise must be obtained between dimensions and autonomy, as for instance in pagers combined with a timepiece to be worn on the wrist.
