Vacuum Clampingsometimes Vacuum Press
Employing air pressure, a method of gluing slices of veneer to substrate. However, vacuum pressing can encompass numerous other gluing tasks, where larger surface flat areas of a project need to be forced together with pressure.Sources: David Shath Square, The Veneering Book.

Variable-SpeedAs in variable-speed headstock (for work with a Lathe) or variable-speed electric motor (for work with a Router)
Variable-speed motors, in the generally accepted use of the term, are motors where the rate of rotation is adjusted by a controller. The intention of the variable speed function in a tool is safety of the tool's operator. On a Router, for example, an overly large Bit, rotating at 24,000 rpms, is dangerous. However, if the rotation rate is reduced to 10,000 rpms, the chances of an accident that will injure the router's operator is greatly reduced.
Image below -- a "do-for" until I get something more permanent -- shows my home-made press for making torsion boxes, but in a pinch would work as veneer press:
Veneers and Veneering
The spelling vise is now usual only in America
Composed of two jaws, opened and closed by means of a screw, which firmly grip and hold a piece of work in position while it is being filed, sawn, or otherwise operated upon, a vise is used by woodworkers and/or carpenters for both hand- and power tool-work, and by machinists or anyone else who works in metal .

An essential tool, operationally, an accessory on Workbenches. Vises consist of two flat plate-like parts, which -- by tightening a screw -- can be drawn together for securing a workpiece while it is cut or smoothed.
("In American English, the "moral fault is spelled vice, while the clamping tool is spelled vise. In British English, vice is the preferred spelling for both the fault and the tool." Merriam-Webster's Dictionary of English Usage, 1994, p. 940).

Above, on the left, is the more commonly used, quick-action metal vise. Below, on the right, is the older style, tightened by a screw, but lacking the utility of "quick-action" for convenient tightening or loosening.
The example on the left comes from Ernest Joyce, The Encyclopedia of Furniture Making, 1979, page 56; the example on the right is from Arthur Wakeling, The Home Workshop Manual, 1930, page 435. In the image on the right, in the lower section, notice the "follower"; according to the size of the workpiece being secured, the follower secures the lower part of the vise.
