Patent number: 5918523Abstract: A system for guiding a cutting tool utilizing a beam generator and a platten having a surface which is capable of presenting a pattern. The beam impinging on the platten is discernable. The beam generator is aligned with the cutting portion of the cutting tool such that the beam on the surface of the platten represents the position of the part of the cutting tool relative to a work piece. An operator may cut a pattern in the work piece by following the pattern on the platten with the beam image on the platten.Type: GrantFiled: April 3, 1998Date of Patent: July 6, 1999Inventor: Jack Cutter

Patent number: 5918525Abstract: A reciprocating saw blade moved in opposite directions parallel to a longitudinal axis is formed with at least one row of longitudinally succeeding teeth having tips all lying on a common tip line parallel to the longitudinal axis and including even teeth all oriented in one direction parallel to the axis and odd teeth alternating with the even teeth and all oriented in the opposite direction parallel to the axis. Each even tooth forms with one of the adjacent odd teeth a double tooth and the tips of the teeth of each double tooth are set laterally of the blade to one side with the lateral set by an offset that alternates longitudinally from double tooth to double tooth to opposite sides of a center blade plane. The offset is the same for all teeth. Each tooth has a relatively steep leading edge and a relatively shallow trailing edge, relative of course to the respective longitudinal direction.Type: GrantFiled: January 14, 1997Date of Patent: July 6, 1999Assignee: Wilh.

Patent number: 5918526Abstract: The object of the invention is a method in a pneumatic oscillating device for observing an obstacle within the length of the work stroke and continuing the oscillating movement after this. The oscillating device includes a double-acting operating cylinder (1), a principal operating valve (6) controlling this, and a reversing valve (4), by which the principal operating valve (6) is controlled. A resistance to the flow on whichever return line (1.31, 1.41) of the operating cylinder (1) is in use, is arranged in order to maintain the return side pressure of the operating cylinder (1) at a level that is clearly higher than the ambient pressure during a work stroke in a normal situation, and sensing the pressure of the return side and, if it drops below a set limit, which is indicated by the movement of the pressure slowing or stopping completely, giving a command to the reversing valve (4) to change direction on the basis of this.Type: GrantFiled: November 28, 1997Date of Patent: July 6, 1999Inventor: Lauri Jauhola

Patent number: 5918527Abstract: A locus control system of hydraulic excavators whereby a target locus for a front device is set beforehand. A control unit calculates a position and posture of the front device based on signals from angle sensors, and calculates a target speed vector of the front device based on signals from control lever devices. Through this calculation process, the control unit maintains the target speed vector as it is when the front device is not near the target locus, and modifies the target speed vector to a vector pointing to a second point on the target locus advanced in the excavating direction by a second distance from a first point located on the target locus at a minimum distance from a tip of the front device, when the front device is near the target locus.Type: GrantFiled: April 23, 1997Date of Patent: July 6, 1999Assignee: Hitachi Construction Machinery Co., Ltd.Inventors: Masakazu Haga, Hiroshi Watanabe, Kazuo Fujishima

Patent number: 5918528Abstract: A fluid flow control for controlling the speed of a piston in a fluid power cylinder is disclosed in which the flow control is located within the confines of the cylinder and includes a rotatable disk having tearshaped slots for communication of the exhaust fluid through the disk and out of the cylinder through discharge ports. Rotation of the disk to selectively position greater or lesser width portions of the tearshaped slot relative to an exhaust discharge opening in the cylinder permits selective, variable adjustment and throttling of the exhaust fluid to control the speed of movement of the piston in the cylinder.Type: GrantFiled: July 22, 1997Date of Patent: July 6, 1999Assignee: Bimba Manufacturing CompanyInventor: E.

Patent number: 5918529Abstract: A hydrostatic axial piston machine with a swash plate achieves a high power with a compact and simple construction. Two cylinder drums are at some axial distance from one another and are in synchronous rotation. Each drum contains a group of concentric cylindrical borings, between which, and at an angle with respect to the axis of rotation of the axial piston machine there is a rotationally locked circular ring-shaped eccentric disc. The pistons are guided against the disc so that they can move longitudinally in the cylinder bores. Each piston consists of two piston segments having the same diameter oriented coaxially to one another and at some distance from one another. The segments are inserted in cylinder bores which are located opposite one another and are connected to one another by a bridge segment. Two support bodies, one on either side of the eccentric disc, are provided for movement on the eccentric disc along a track.Type: GrantFiled: August 1, 1997Date of Patent: July 6, 1999Assignee: Linde AktiengesellschaftInventor: Franz Forster

Patent number: 5918530Abstract: A hydraulic torque motor comprising a cylindrical housing (1), a piston (30) which can only be moved axially in the housing (1) and a rotor (20) which can only be rotated and which extends through the piston (39). The rotor (20) has a spiral groove (21) and the piston (30) has an engagement element (39) which extends radially inward in the groove (21). The piston (30) has a cylindrical section (31), each end of which has a circular end flange (34, 35), which abuts sealingly and slidingly against the housing's (1) boring. The housing (1) has a center flange (5) which projects radially inwards between the end flanges (34, 35) and is arranged to abut slidingly against the cylindrical piston section (31). The end flanges (34, 35) and the center flange (5) and those sections of the housing's (1) boring which are located between the flanged (5, 34, 35) define two cylinder spaces (37, 38).Type: GrantFiled: August 6, 1997Date of Patent: July 6, 1999Assignee: Scana Skarpenord ASInventors: Fred Kanton, .O slashed.ystein Klonteig

Patent number: 5918533Abstract: A system for making tortillas includes a sheeter, a roller/heater, and an oven. Tortillas are die cut into an oblong shape in the sheeter. The roller/heater rolls the tortillas into a round shape and conductively heats the tortillas simultaneously on the top and bottom surfaces, gelatinizing the food product and sealing in moisture. The tortillas are then baked in an oven. Slot marks on the tortillas are avoided as the roller/heater has upper and lower belts have continuous surfaces.Type: GrantFiled: November 21, 1997Date of Patent: July 6, 1999Assignee: Lawrence Equipment, Inc.Inventors: John C. Lawrence, Mark Lawrence, Eric C. Lawrence
