Abstract: A system for electronic safeguarding against burglary, or for monitoring, having a signal emitter and a receiver for receiving signals from a resonance label if the label is located in the zone of emitted signals. The system is adapted for use in stores, such as department stores, to detect unauthorized removal of items that carry a resonance label. The receiver evaluates the received signals to trigger an alarm signal upon detection by a receiver of a signal from a resonance label. Plural emitter-signal pairs are provided in which the respective emitter signals are wobbled at staggered frequencies within a broad frequency band. The emitter is also operative to emit and inoperative not to emit periodically only during alternating time phases and the receiver evaluates signals received by it for triggering the alarm only during the intervals between the signal emitting state of the emitter.

Abstract: A line blind valve is disclosed which includes a housing having opposed similar housing halves with resilient sleeve units which compressibly engage each other in the valve open condition and engage opposite sides of the gate or blind in the valve closed condition. The line blind valve provides visibility of all gate edges so as to give a positive indication that the gate or blind has passed completely through the seals. Lockout is also provided when the gate or blind is closed. Each sleeve unit has a plurality of compression holes extending axially and arranged at intervals relative to the circumference of the sleeve. An encircling stiffening ring of harder material is encapsulated in each sleeve so as to be positioned at the inner end of the compression holes. The line blind valve construction of the present invention results in no leakage to the outside when the valve is fully open and no leakage to the outside or past the gate internally when the valve is fully closed.

Abstract: Apparatus for carrying a patient infusion device, such as an intravenous-fluid-containing bag or infusion pump. The apparatus includes an infusion device carrier that has a support connector from which a coupling rod extends. The support connector and coupling rod are releasably received in a support receptacle that is carried by a mobile stretcher, an infusion device support stand, a wheelchair, a bed, or a wall mount. The coupling rod includes a throughbore to receive a transversely slidable detent carried by the support receptacle, and alignment indicia are carried on each of the support connector and the support receptacle for properly aligning the two elements to permit them to be securely connected together. The releasable support connector permits the infusion device to be transferred from one mode of carrier to another, thereby eliminating the need for a separate person to guide an infusion device support stand to accompany a patient being transported.
