Abstract: Disclosed is a grinding fluid supply device of a lens grinding apparatus. The grinding fluid supply device includes first grinding fluid supply means for supplying a grinding fluid in a tangent direction of a circular grinding wheel, which has a grinding surface formed on its circumferential surface, with an interval above a grinding surface and allows an upper portion and a rear side portion of the grinding surface to be covered with a curtain of the grinding fluid spaced from the grinding wheel when a processed lens is subjected to a grind processing with the grinding surface of the grinding wheel by rotatively driving the grinding wheel around an axis; and second grinding fluid supply means for insufflating the grinding fluid to the grinding surface.

Abstract: The invention relates to a cutting apparatus for cutting out at least one strip from a roll with rolled up sheet like material. The apparatus is equipped with finger means which lift out a suitable distance from the roll the layer from which the strip will be cut out. A cutting tool means is placed near each finger means in order to cut through the material. Each cutting tool means is a motordriven, rotating blade driven with a peripheral speed which is considerably higher than the speed with which the cutting apparatus is moved along the roll, or an oscillating knife or the like. During the cutting out operation the cut out strip is rolled up on a rotating roll core means with a torque-adapted rotation. A strip-tensioning arrangement distributes the tensile forces from the rotating roll core means to the strip at the middle of the width of the strip and is placed at the middle of the width of the strip between the cutting tool means and the roll core means.

Abstract: A miter saw including a base having a support surface for supporting thereon a workpiece and a turntable mounted on the base for rotation about a generally vertical axis. A support is mounted on the turntable for movement therewith and a saw arm is mounted on the support for pivotal movement about a horizontal bevel angle axis such that the saw arm is adjustable to cut the workpiece at a selected bevel angle, and the saw arm being mounted on the support for pivotal movement about a second horizontal axis perpendicular to the bevel angle axis to allow movement of the saw arm between cutting and non-cutting positions. A reversible fence is removably connected to the base to support the workpiece on the base. The fence has opposite ends such that one end has a vertical edge portion for supporting the workpiece during conventional miter cutting of the workpiece and the other end has an angled edge portion for supporting the workpiece during compound miter cutting of the workpiece.

Abstract: A laser arbor is provided that will display a cutting line on a work piece to be cut by a rotary saw. The laser is operated by a centrifugal switch mounted within the laser arbor along with a laser diode or the like and a battery. Because of the rotation of the laser with the blade and the persistence of the human eye, the moving light spot from the laser appears as a single line, hence it is not necessary as in the prior art to produce light divergence in the plane parallel to the blade plane. For that purpose, it is preferable to employ a light source having a wavelength that lies in a region to which the eye is sensitive, which in practice will typically mean a wavelength in the upper region of the red. Placement of the laser inwardly from the cutting surface of the blade eliminates the danger of any damage occurring to the laser as a result of debris from the cutting process.

Abstract: Point needles in a conveying cylinder of a rotary press are caused to follow a curve course which securely fastens a web to the cylinder while eliminating transport damage to the printed products as well as reducing paper waste. The needle tips of the point needles are moved along their path by the superimpositioning of two pivot movements, one of which is accomplished by a point holder arm and the second of which is accomplished by a rocker. The two cooperate to form a level four member swivel joint.

Abstract: A multi-position adjustable work stop assembly employs a traveling gauge assembly that cooperates with independently adjustable and inexpensive location stops. The gauge assembly is moveable along a fence to define a plurality of work locating positions determined by the location stops. An engagement or contact member on the gauge assembly selectively intercepts the location stops to precisely locate the gauge assembly in the desired positions. The engagement member is an arm mounted for movement between first and second positions on the gauge assembly. In the first position the engagement member intercepts the location stops when the gauge assembly is moved longitudinally on the fence. In the second position the engagement member clears the location stops during such movement.

The method requires the introduction of a flaw in an optical fiber to be cleaved, and the application of predetermined stress and strain to the optical fiber in the vicinity of the flaw to cause curved-angle cleaving of the optical fiber at the flaw. The apparatus of the present invention includes first and second pairs of optical fiber clamps separated by first predetermined distance, a flaw-producing device that produces a flaw in a fiber clamped between the clamps, and a force-applying device that applies a substantially concentrated force to the fiber at a second predetermined distance from the first pair of clamps, the flaw-producing device being located between the force-applying device and the second pair of optical fiber clamps at third predetermined distance from the force-applying device. The first, second and third predetermined distances are selected in order produce a curved-angle cleave in the optical fiber.
