Abstract: The instant invention is a door frame adjustment apparatus that is four-sided and horizontally adjustable consisting of a slideably adjustable scale component, and corresponding adjustable bar component, vertically and horizontally aligned adjustable locking members, adjustable hinge units, horizontally aligned bubble leveling components, stabilizing members, magnetic stripping continuously affixed to the edging of one lateral side thereof and to a portion of a top side thereof and spacing within the lateral sides to facilitate affixation of door frame units to interior walling of an opening within building framing serving to encase the door frame unit.

Abstract: Apparatus, for measuring the velocity of flow of a gas, is of the type comprising two ultrasonic probes arranged opposite to one another and transmitting pulses following upstream and downstream paths which are inclined with respect to the direction of flow. A commutation device which enables these two paths to be established is actuated in such a way as to effect change-over of the probes both on transmission and on reception, the commutation command signals being phase shifted with respect to the transmission pulses.
