Abstract: HIGH EFFICIENCY LIGHTING UNITS     AND SYSTEMS USING SAME                    Abstract of the Disclosure A lighting unit comprising a lamp and a reflector provides high intensity, high efficiency, even illumination over an area of particular shape and size and has a cut-off angle which enables a person to approach close to the lighting unit without seeing the lamp or its reflection. The reflector comprises at least two spaced apart curved reflector surfaces which join each other along an edge line in a plane behind and spaced from the lamp. Points on the curve line of each reflector surface are spaced progressively farther away from the lamp than the edge line. Some points on the curve are located on the side of the plane remote from the lamp. The lighting unit, which may employ reflector surfaces in addition to those above mentioned, may be employed in systems wherein it projects light upwardly for downward reflection from a ceiling or projects light downwardly directly onto a work surface. The lighting units located in some systems are so that the reflector opening is near eye level of a standing or sitting person.

Abstract: ABSTRACT OF THE DISCLOSURE         A novel stator assembly, D.C. electric motor, and method of controlling the speed of the motor is described.  The stator assembly includes a pair of field poles, each having a field coil wound around a shank portion,and a plurality of separately excitable field control coils wound individually around the field pole legs defining a face portion of the field poles. The field poles also have a core portion which provides a magnetic path between the shank and face portion. This core portion permits the magnetic flux in the field poles to shift across the face portion when one or more of the field control coils are energized magnetically subtractive to the flux generated by the field coils. The speed of the motor may be controlled by energizing the field control coils and controlling their polarity with respect to the field coils.  A motor controller for the motor according to the present invention is also described, and is particularly useful in an electric vehicle application.

Abstract: ABSTRACT OF THE DISCLOSURE         An improved breathing protective apparatus has an inhalation regulator and a primary source of breathing air supplied to the user through a pressure line.  An exhalation regulator with a return line is connected to a vacuum source to remove exhaust gases from the work area.  The apparatus has a positive pressure and free flowing regulator which provides an extra measure of safety in a toxic environment and to provide low breathing resistance under high work load conditions.  The arrangement is such that if the exhalation regulator is bypassed for exhaust without vacuum conditions, positive pressure and the free flowing regulator is automatically eliminated to save emergency air for escape of the user from a contaminated environment.

Granted: 1985-05-14
Abstract: ABSTRACT OF THE DISCLOSURE           An arrangement for measuring the contour of a two or three dimensional surface in which a redundant configuration of distance measuring systems is positioned above the surface being measured.  Each distance measur-ing system monitors distance measurements to a point proximate the surface as the measuring point is moved across the surface.    The distance measurements are taken from a sufficient quantity of points on the surface such that a sufficient quantity of data is obtained to define the system geometry and also to define the position of each measurement point.  The data is transformed by recognized mathematical techniques into the coordinate positions of all of the measured points on the surface.          I: one embodiment for measuring the contour of a three dimensional surface, a tetrahedral arrangement of four distance measuring interferometers includes three interferometers positioned in a planar array above the measured surface and a fourth interferometer positioned at a central apex thereof.  A retroreflector is placed adjacent to the measured surface to define the measuring point, and is sel-ectively movable across the measured surface.  A tetrahedral truss is positioned above the measured surface, and each interferometer has a beam steering head at one corner of the truss to aim the interferometer beam at the retroreflector during movements thereof.  Each interferometer further includes a servo control system for controlling the beam steering head to maintain the interferometer beam aired at the retroreflector.

Abstract: ABSTRACT OF THE DISCLOSURE           The invention provides a loading system for the charge of an annealing furnace of the kind intended for the treatment of a stack of coils mounted one on top of the other with their central cores in register with one another, a protective heat exchange gas atmosphere being circulated around the stack within a cylindrical bell-shaped muffle cover to heat and subsequently cool the charge.          The system comprises a diffuser member having a gas impeller at its centre that receives gas passing downwards through the coil cores and discharges it radially into the annular space between the stack and the muffle cover in a preferred helical path.  The stack rests on a load member placed on the diffuser member, a convector plate is interposed between each pair of superimposed coils and the stack is completed by a top member and a plug member.  Each of the load members, the convector plate and the top member has a plurality of radially extending gas flow passages that permit the gas to pass from the annular space to the coil centres in heat exchange contact with the respective ends of the coils.  Thus even distribution of the gas and consequent rapid even heating of the coils is obtained, the flow plug also augmenting a helical down-ward gas flow in the registering coil cores to the impeller.
