Abstract: A B S T R A C T     A thread forming screw is formed from a blank having a cylindrical shank and a tapered conical end.    helical screw thread is formed on the shank and a tapered lead-in section is provided at one end of the screw for forming a thread in a work-piece.  The lead-in section includes a plurality of spaced lobes each having outer convex surfaces and they collectively define a thread forming section on the tapered end of the screw.  Concave surfaces formed in the tapered end extend between and space the lobes circumferential and provide substantial concavities between the lobes to reduce friction and turning torque when forming threads in a workups.  Curved ramp surfaces join each of the concavities and each of the lobes to eliminate sharp interfaces between the lobes and the concavities.

Title: Method and apparatus for forging of crankshafts in  presses
Inventor: RUT TADEUSZ
IPC: B21K1/08
Filed: 1984-12-06
Granted: 1987-10-20
Abstract: ABSTRACT     A method and an apparatus for forging crankshafts especially on presses comprising forming only one crank web during one working stroke in such a way that a hot bar portion is clamped in two places situated at some distance which are destined to be the crankshafts main bearing journal and adjacent crank pin in the finished product.  Between these places a bar portion is upset lengthwise to the bar axis and simultaneously bent and joggled radially to this axis. At the beginning of the working stroke the upsetting velocity is higher than the bending velocity,whereas at the end of the working stroke the upsetting velocity is lower than the joggling one. The following crank webs are forged and directed at proper twist angle during successive working strokes of the press crosshead. The device for  orging crankshafts by this method comprises a base which consists of beams 4 and cross--members 12 and 25. The head 3 of the device is assigned for reciprocal movement in relation to the base. Between head 3 and parts 4 and 25 of the base there is a pair of movable, mutually coupled die holders 5 and 8, from which the top die holder 5 is led perpendicularly or at an oblique angle in relation to the head movement and the bottom die holder 8 is connected with the base by means of articulated connectors 6 and 7. Clamping die inserts 10 and 11 for gripping the forged material are fastened in die holders 5 and 8. The device is also equiped with a second pair of die holders 13, 12, 12a, 4d, which remain stationary and are fixed to the base during the working stroke of the press by means of a clamping mechanism 14 and 15. Die inserts 22 and 23 for forming crank webs and angle die inserts 17, 18 and 20 for setting crank webs at proper twist angles are mounted into the said stationary pair of die holders.

Abstract: STEAM TURBINE-GENERATOR THERMAL       PERFORMANCE MONITOR         ABSTRACT OF THE DISCLOSURE    A  thermal performance monitor informs the operator and result's engineer of the economic losses, efficiencies, deviation in heat rates and power losses of operating a steam turbine-generator system at its controllably selected pressure and temperature.  Specifically temperature and pressure signals are generated at various points in the system along with the control valve position signal and the electric output signal from the electric generator. This data is processed along with the corresponding design values and the economic losses due to temperature deviation, pressure deviation and exhaust pressure deviation from design are calculated.  Other calculations produce a comparison of efficiencies of the turbines in the system and consequential power losses.

Abstract: ABSTRACT OF THE DISCLOSURE      An  apparatus  and  method  for  using a  multi-purpose tool having  a handle with a shaft affixed thereto and a cylinder assembly disposed to  longitudinally slide on the shaft between positions in which the shaft is fully extended or fully retracted.  While in the fully retracted position, a cylinder having a plurality of chambers housing different tips may be rotated about its axis, which is offset from the shaft,  until the desired tip aligns with and engages the shaft in coupling engagement.  The shaft is then extended to its  fully  extended  position,  thus  extending  the tip and permitting  free  rotation of  the  working  tip  for use  in performing work on a workpiece.  Changing the tip requires retracting the shaft,  rotating the cylinder to engage the next desired tip, and extending the shaft back to its fully extended position.  The multi-purpose tool may be attached to a power tool for power driven rotation.

Abstract: ABSTRACT OF THE DISCLOSURE    A fiber scope of the present invention is side-viewing type one fundamentally constructed from the combination of one image guide and two light guides disposed on both sides thereof in an objective part.  This fiber scope is suitable for the observa-tion of the surface of long articles assembled with narrow gaps therebetween as in an assembly of nuclear fuel rods in a nuclear reactor and a wide field of view can be secured even if an object to be observed stands within point-blank of an objective part.  Also the construction, by which a plurality of long articles can be simultaneously observed or also the observation of a state in the scanning direction can be carried out, is proposed.  In the case where an object, which is under a radioactive environment, is observed, highly radiation resistant optical fibers are used.

Abstract: ABSTRACT           FLUID LOSS CONTROL IN WELL CEMENT SLURRIES        A polymer of monoallylamine, preferably a water-soluble polymer of monoallylamine, whether in free (i.e., unneutralized) form or in salt (i.e., partially or completely neutralized) form is used in conjunction with a sulfonated polymer such as a water-soluble lignosulfonate, condensed naphthalene sulfonate, or sulfonated vinyl aromatic polymer, to minimize fluid loss from the slurry during subterranean well cementing operations.          The polymer of monoallyl amine may be a homopolymer or a copolymer, and may be crosslinked or uncrosslinked.  These components interact with each other in the presence of water to produce a gelatinous material that tends to plug porous zones and minimize premature water loss from the well cement slurry when present in the subterranean well formation.  In addition, the gelatinous material so formed prevents de-stabilization of the slurry in the well formation.
