摘要:
The invention relates to a method for controlling a homogeneous batch (1) of pressurised fluid cylinders (2) during at least part of the use cycle of said cylinders. According to the invention, each of the cylinders (2) is provided with a valve (3) having an electronic device (4) including at least one sensor (14) for measuring the pressure (P) inside the cylinder (2), a system (44) for storing/acquiring and processing data and an electromagnetic wave transmitter (34), for example using radio frequency, designed for the remote transmission of at least one of the following items of information: the identity of the cylinder (2) and the pressure (P) measured inside said cylinder. The method includes a transmission step in which all of the cylinders (2) in the batch (1) transmit at least one item of information of the same type when they are in the same phase of the use cycle at the same time and a step in which the same-type items of information transmitted by the cylinders are compared for the automatic detection of an anomaly in the batch (1).

A seal anchor for pipe couplings suited for frictional connection of smooth-ended pipes. The seal anchor has a housing, and at least one sealing element, for example of rubber-elastic material, arranged therein. The anchor may be of generally L-shaped cross-section and has a first limb extending in the axial direction and a second limb extending at an acute angle to the first limb. The anchoring element blank is provided with slots which run across its width in the longitudinal direction relative to the limbs and between the limbs. One or more webs span the slots to join adjacent limbs.

Erroneous installation of fuel cell fuel cartridges, in which different kinds of fuels are received, on an apparatus is prevented The fuel cell fuel cartridge has a container body (2) that is provided with a fuel supply opening (10) for supplying a fuel and with a connecting circular tube body (20) surrounding the fuel supply opening (10) and has a fuel storage chamber that is formed inside the container body (2) to receive the liquid fuel to be supplied to a fuel cell. The shape of the circular tube body (20) varies according to the kind of fuel stored in the fuel storage chamber.

An exterior impact and abrasion resistant protective coating (14) is provided on the surface of the vessel (12) having information (16, 18, 20) provided on the exterior surface thereof to form a container (10) for storing and dispensing gas under pressure. The coating (14) is sufficiently transparent such that said information (16, 18, 20) is visible through the coating (14). One advantage of the invention is that any labels (16, 18, 20) on which the information is provided are protected against abrasion and other damage that would otherwise obscure the information thereby reducing the frequency with which the labels (16, 18, 20) need to be replaced.

A neck ring has inwardly projecting fingers for engaging a threaded neck of a gas cylinder. The fingers are flexible and sloped upwardly to securely hold the neck ring on the cylinder while permitting removal without damaging the neck ring. Identification labels are mounted on flat, translucent or opaque tags. The separate tags are hinged and spaced apart to accommodate differently configured cylinders.

The system includes an electronic label (1) and a data terminal (6). The electronic label (1) is provided with a device for the emitting of electromagnetic waves (8) fixed to a ring (2) of the bottom of the protective bell (5). The data terminal (6) is coupled to a detachable read/write head (7) that can be inserted, as desired, into the bell (5) directly facing the label (1) bearing ring (2) to transmit information elements between the data terminal (6) and the label. The system may be used for the automatic identification of gas cylinder type articles.
摘要:
A sleeve label for application to the peripheral exterior of an article such as a gas cylinder, including a flexible label sleeve having a circumference and a central axis, and first and second portions parallel to its axis and extending the length of the label sleeve; an elongated, stiff strip having first and second edges extending the length of the strip, and having an inner face and an outer face; the first sleeve portion being attached to the strip to extend from and be flexible about the first edge of the strip, and the second sleeve portion being attached to the strip to extend from the inner face at a location intermediate the edges of the strip; the strip being on the exterior of the label sleeve, with the second edge of the strip and the outer face of the strip being exposed; the strip being pivotable about its first edge to flex the sleeve at and about the first edge of the strip to turn the outer face of the strip inwardly against the label sleeve and simultaneously pull a segment of the sleeve outwardly of the strip, and thereby decrease the circumference of the sleeve; and securing means such as adhesive for securing the outer face of the strip to the sleeve. The adhesive may be pressure sensitive adhesive and include a removable protective cover over the adhesive. The sleeve preferably has a nonslip polymeric material on its inner face, most preferably in a dot matrix of protrusions to interfit with surface roughness of a gas cylinder or the like.

An anesthetics monitoring device includes an anesthetic vaporizer, from which the anesthetic can be supplied to a setting device supplying dosed amounts of anesthetic to an anesthetics device for dispensing the anesthesia to a patient. The device has a coding for the unmistakable assignment of the setting device to the type of anesthetic used. An automatic recognition of the anesthetic used and a setting to a metering and control unit for dispersing the anesthetic is guaranteed. Any incorrect metering and incorrect setting is prevented. For this purpose, the coding is brought into an operative connection with a receiver provided between the setting device and the anesthetics dispersing device. The receiver is equipped with a scanning apparatus which is connected to the metering and control dispensing unit by means of signal transfer lines.

An information tag holder for use on the screw-threaded neck of a gas cylinder is made from a plastic sheet which has at least two thread-engagement portions with cut-outs for frictionally engaging over the screw-threads, and a tag supporting surface between the thread-engagement portions. In use, the holder is folded transversely, so that the cut-outs in the respective portions are in register and the holder is applied in this manner to the cylinder. The respective thread-engagement portions are differently dimensioned so that when the cut-outs are in register, the tag supporting surface is inclined.
摘要:
An assembly for recognizing gas cylinders or the like, each provided with a valve and a protection cap for the latter and with a carrier for a code to be read by a reading apparatus provided on the neck of said cylinder. According to the invention on said neck a ring is secured which is adapted for transport of the cylinder in the suspended condition by means of a lifting tool, a removable code carrier being fixed on said ring. In particular said ring is adapted or removably mounting thereon a special protection cap, in particular by means of securing pins, said cap, at the same time, providing a protection of the securing means of the code carrier, and, in particular, comprising a hinged cover for passing connecting means.
