Abstract: This invention relates to a humane animal live trap for application to the immobilizing of various animals and mammals. The device consists of a generally vertically positioned, compressed sleeve or cylindrical body of a generally resilient interwoven spring-like stranded material forming by strands interwoven at acute angles with each other a hollow doubly tapered cylindrical opening the sleeve is adapted to elongate when the trigger is actuated and the compressed sleeve is released by the sleeve guards, from its state of compression and circumvallates the animal or animal part that entered in to the hollow sleeve with its central tapered cylindrical opening, and tripped the trigger located centrally at the sleeve bottom. The sleeve is comprised of a loop series which is formed by the upper ends of the resilient strands, to allow compressing and depressing of the centrally doubly tapered cylindrical opening to release the captured animal and reset the trap sleeve.

Abstract: A circuit arrangement for protecting the remainder of a plurality of parallely operated transistors in the event any one of the transistors fails in a shorted condition. An open circuited failure has no adverse effect upon the operating circuit. Each transistor includes a "slow" turn-off diode with respect to the period of the input drive signal, coupled in series between a common input signal-feed point and the base of the transistor to which it is connected. The diodes are poled to block the collector B+ supply potential appearing at the base of the respective shorted transistor, thus preventing the B+ supply potential from being applied to the base of the remaining transistors. Additionally, a respective fusister is connected in series between each emitter and the load circuit line in order to thereafter remove the failed transistor from the circuit and to balance the transistor currents during normal operation.
