Abstract: An inflation for a teat cup is made in the form of a silicone tube adapted to fit into, and seal the ends of, a teat cup. Pulsating pressure is applied to the outside of the inflation within the teat cup, and a low pressure line is attached to the downstream end of the inflation. An integral annular bead is spaced slightly less than a teat's length below the upstream end of the inflation. Axial ribs are spaced around the circumference of the tube upstream of the annular bead. The bead and ribs are resistive of collapse and therefore provide a gentle massaging action on the teat when the pulsating pressure is applied. In one important embodiment, the head of the inflation is provided with a pliant skirt and an annular cushion that fit against the teat and udder to minimize irritation and maximize retention of the inflation.

Abstract: A method for producing a refined smoke vapor and a refined smoke condensate for imparting smokey flavor and color to comestible products, a smoking method employing the refined vapor or the refined condensate and comestible products smoked with the vapor or the condensate.

Abstract: An automatic fire extinguishing apparatus with a heat fusible element comprising inner and outer members held together by a fusible material blocking the flow of fire extinguishing agent until the contiguous temperature reaches a pre-determined threshold value whereupon the inner and outer members separate to release the fire extinguishing agent. A fire extinguishing apparatus having both manual and automatic release mechanisms.

Abstract: Methods and apparatus are disclosed for inhibiting the unauthorized copying of ROM-resident computer software or the like, for example, the audio-visual display of an electronic video game. A protection circuit including encryption/decryption means is coupled between the microprocessor and the ROM-memory and is operable in a first mode to properly encrypt/decrypt the program information according to a first algorithm and in a second mode to prevent proper encryption/decryption. The address-data buses are monitored by the protection circuit to detect an invalid program event, such as may occur when a microprocessor emulator is used to attempt an unauthorized copying or "dumping" of the program information. Upon detection of the invalid program event or "trap condition", the protection circuit switches to its second operating mode thereby to prevent copying of the decrypted program information.
