Here's 1990s footage of a cryonics business named "Alcor," in 1990s Arizona. Cryonics, in short, is the process of preserving a body under cold conditions with the hope of reviving the body in the future. This is clip 6 of 6. 

Clip begins with a close-up on a spinning machine, possibly a kind of mixer.

We then see an extreme close-up of a monitor, which is showing periodic activity, like a pulse.

A man’s hand rests on a machine. The machine is monitoring something and providing feedback.

Two Alcor technicians are wearing “operating room” scrubs. Their hair is covered and their hands are gloved. Both also wear face masks and goggles. A medical cabinet that's open stands behind them.

An Alcor technician holds a device up to the ceiling and looks at it carefully — as if he were using a hand-held microscope that functions using room light.

Two technicians work on a body that has its head exposed. The rest of the body is covered with sheets of plastic. There’s a close-up of a staple-like device being pressed into the deceased person’s forehead.

Two technicians are sitting and waiting, monitoring a device, looking somewhat puzzled.

There’s a wide shot of the “operating room,” revealing a large circular overhead lamp positioned over the deceased body. Several technicians are working on the deceased.

Several metal devices spin counterclockwise. One device is a “SARNS” device, which is a heart-lung machine used in medical procedures. The devices appear to be supporting the flow within nearby tubing.

Two technicians make adjustments to what appears to be a modified gurney. To the left of the gurney stands a large metal tank that’s labeled “ALCOR.”

In a back room, a technician struggles to put on his “operating room” scrubs while wearing a face mask, a large protective face shield, and shoes.

Technicians are hunched over a sink. Buckets are on the floor.

One technician is hunched over and fixing a SARNS-like device, which is beside four similar devices.

A man in scrubs, though without a face mask, works alone on the torso area of the deceased.

One technician, who is standing near the deceased person, hands a network of tubing to another technician.

In the clip's final scene, a female technician brings a white, plastic-like bag, perhaps filled with body parts, to a wooden container that looks like a large coffin. Another technician follows her, holding up a bunch of wiring. After closing the white plastic-like bag, the bag is lowered into a bucket that is within the wooden container; the bucket appears to have a number of wires and tubes going into it.
