摘要： A clamping device for holding cylindrical workpieces having a nominal radius R which varies from a minimum of (R-A) to a maximum of (R+B), where A and B are the limits of the tolerance range for the nominal radius. The clamping device includes opposed clamp halves each having a clamp face adapted to be moved toward and away from one another and each of the clamp halves carrying a rigid collet element adapted to engage on opposite sides of cylindrical workpieces when the clamp halves are moved toward one another. According to the disclosure, each of the collet elements has a semi-cylindrical clamping surface extending inwardly from the clamp face of the respective clamp half. Each semi-cylindrical clamping surface has a radius substantially equal to R+B) with the center of the radius being offset outwardly of the clamp face of the respective clamp half an amount at least equal to (A+B). Preferably, the center of the radius is offset an amount at least equal to (A+B+C), where C is the tolerance deviation permitted to the radius (R+B).

Preferably, the center of the radius is offset an amount at least equal to (A+B+C), where C is the tolerance deviation permitted to the radius (R+C). Additionally, each clamping surface is comprised of individual surface portions mounted for independent flexing movement to allow the collet to further compensate for workpiece tolerance variations.

摘要： A method and apparatus for treating a sheet of pastry dough to cause it to have a woven, lattice-work appearance by cutting a plurality of polygonal openings through the sheet in a predetermined pattern with sides of each opening being aligned with sides of adjacent openings to produce aligned rows of openings and deforming the sheet in the portions remaining between the openings by depressing grooves aligned with sides of the openings into the sheet to make it appear that the sheet is comprised of overlapping dough strips.

摘要： A pressure relief valve includes a valve body having an axial inlet port and a lateral outlet port, with an enlarged bore extending between such ports. A valve bonnet attached to the valve body slidably guides a poppet for movement between closed and open positions for closing and opening the inlet port. A seal ring positioned in the bore adjacent the inlet port sealingly surrounds the poppet in its closed position. The seal ring is axially compressed between a retainer ring and a backup surface, and a ring nut threaded in the bore compressively engages the retainer ring. The ring nut is located entirely on the inlet port side of the outlet port so it does not inhibit flow to the outlet port when the poppet is open. A poppet guide bore in the bonnet extends inwardly from a bonnet end surface, and a pair of concentric recesses of different diameters also extend into the bonnet from the end surface. One recess receives a seal ring positioned in surrounding sealing relationship with the poppet, and the other recess receives a push-in retainer for retaining the seal ring in its recess. A small diameter stem on the poppet extends into a bonnet spring receiving bore and has a rounded end received by a conical recess in a guide disc. Close fitting cylindrical locating surfaces are used for providing accurate concentricity between the bonnet and body, and between the retainer ring and the bore.

摘要： A plug valve having a valve body with a cylindrical plug receiving opening extending therethrough having at least one terminal end thereof outwardly chamfered. Fluid inlet and outlet passageways communicate with the receiving opening and are chamfered at the areas of communication therewith. A plug member includes a cylindrical plug portion closely received in the body receiving opening. This plug portion has a transverse fluid flow passage which is selectively rotatable into and out of alignment with the valve body inlet and outlet passageways. Axially spaced apart circumferential sealing members disposed on both sides of the flow passage prevent fluid flow outwardly of the receiving opening. An inlet passageway sealing means disposed in the plug portion side wall intermediate the opposite flow passage ends sealingly surrounds the passageway in the valve closed position. A fluid relief channel communicating between the flow passage and plug portion side wall relieves fluid pressure through the outlet passageway as the valve is moved to the closed position. The plug portion advantageously includes a thin coating of plastic material for enhancing its fluid sealing relationship with the receiving opening and for improving ease of rotation between the valve opened and closed positions. The plug member is axially retained in position in the receiving opening by a snap ring at one end and by a handle at the other end. The handle is rotatable only between positively defined maximum valve opened and closed positions. Spaced apart circumferential grooves included in the plug portion side wall receive the axially spaced apart sealing members and at least the bottom walls of these grooves are also coated with the plastic material.
