Abstract: ABSTRACT A combination safety and service valve including a body having a sealing portion for closing an opening in a high-pressure tank and an external portion which, when the sealing portion closes the tank opening, is positioned externally of the tank utilizes a ball chamber in its flow passage and a spherical ball loosely received in the chamber for preventing the escape of contents of the tank if the external portion were to separate from the sealing portion.  The ball chamber is adapted to sealingly accept the ball at its outlet end, and the ball is of such size that a pressure differential across the ball chamber urges the ball into sealing engagement with the ball chamber outlet. A stem associated with the external portion of the valve body prevents the ball from engaging the chamber outlet end until the external portion is separated from the sealing portion.

Abstract: ABSTRACT OF THE DISCLOSURE           An improved efficiency propulsion system and method of improving the efficiency of a vessel operated in deep and shallow water depths and at constant or variable loaded and ballast water lines contemplates the use of a variable diameter propeller means as shown in Figure 1 capable of varying between a maximum extended diameter D and a minimum effective diameter d mounted on a  propeller  shaft  20  having  an  axis  of  rotation displaced from the bottom keel of the ship a distance less  than one-half  the maximum diameter D of  the propeller means  In this way, because of the use of the variable diameter ship propeller, the propulsion shaft may be located closer than otherwise permissible to the bottom keel of the ship which has the result of lowering the top blade tip trajectory relative to any particular chosen water  line  and  also providing  space  for  a generally larger diameter more efficient propeller installation.  Additionally, because of the ability to decrease the diameter of the propeller when desired, the bottom blade tips of the propeller may be maintained above the bottom keel of the ship when the ship is operating in shallow waters.  However, upon return to deep water depths in the open sea, the diameter of the propeller may be extended to gain optimum operating efficiency.

Abstract: Abstract Pen A pen comprises an elongated one-piece barrel having substantially rigid tip end and head end por-tions joined to each other by an intermediate integral flexible portion, whereby the barrel can be bent at the flexible portion, and a writing tip at the distal end of the tip end portion.  A substantially rigid tubular cap member is telescopically received over the tip end portion of the barrel such that it can be moved along the barrel between (1) a retracted posi-tion in which it overlies part of the tip end portion and substantially all of the flexible portion, thus exposing the writing tip for use and rendering the pen substantially rigid, and (2) an extended position in which it covers the writing tip and leaves the flexi-ble portion exposed, thus protecting the writing tip and rendering the pen flexible.  Interengaging cou-pling elements on the cap and the tip end portion of the barrel releasably retain the cap member in each of the retracted and extended positions.

Abstract: Abstract of the Disclosure To form a turbine engine component, metal airfoils are positioned in an annular array.  Outer end portions of the airfoils are embedded in a wax outer shroud ring pattern and inner end portions of the airfoils are embedded in a wax inner shroud ring pattern.  A mold is formed by covering the metal airfoils and the shroud ring patterns with ceramic mold material.  The wax of the shroud ring patterns is then removed from the mold to leave inner and outer shroud rink mold ring cavities.  The shroud ring mold cavities are filled with molten metal which  is solidified to form inner and outer shroud rings interconnecting the airfoils.  To accommodate thermal expansion of the airfoils relative to the shroud rings, a slip joint is provided between at least one end portion of each of the airfoils and a shroud ring.  To enable the slip joint to be formed, molten metal solidifies in the shroud ring cavities free of metallurgical bonds to the airfoils.  The shroud rings may be formed of metal having different compositions and crystallographic structures than the metal of the airfoils.

Abstract: A B S T R A C T            Method and Atomic Force Microscope for Imaging Surfaces with Atomic Resolution A sharp point (5) is brought so close to the surface of  a  sample  (4)  to be  investigated  that  the  forces occurring between the atoms at the apex of the point (5) and those at the surface cause a spring-like cantilever (7) to deflect. The cantilever (7) forms one electrode of a tunneling microscope, the other electrode being a sharp tip (8). The deflection of the cantilever (7) provokes a variation of the tunnel current, and that variation is used to generate a correction signal which can be employ-ed to control the distance between said point (5) and the sample (4), in order, for example, to maintain the force between them constant as the point (5) is scanned across the surface of the sample  (4) by means of an xyz-drive (3).    In certain modes of operation, either the sample (4) of the cantilever  (7)  may be excited to oscillate in z-direction.  If  the  oscillation  is  at  the  resonance frequency  of  the  cantilever (7),  the  resolution  is enhanced.

Abstract: Abstract of the Disclosure In the apparatus of the present invention for processing data contents of totalizing memories, item signs and arithmetic signs are preset in memory terms to be processed such as weight, price and so forth.  The apparatus comprises an internal memory having a matrix-like memory processing table where processing numerical expressions are set by combination of items signs and arithmetic signs at predetermined addresses of the table constituted by the totalizing memories with designated addresses and the memory processing timing in respect of such memories; and an external input means for designating a desired address in the internal memory and changing and inputting the processing numerical expression of the matrix-like table thereto.  Thus the contents of the totalizing memories can be altered and set easily by the numerical expressions which are changeable by such external input means, hence facilitating alteration of the contents to be totalized at the user level.

Abstract: CHIPPER KNIFE ASSEMBLY                         ABSTRACT OF THE DISCLOSURE The present invention is a knife assembly for a chipping canter or a mechanically similar device. In its basic form it comprises four parts: a knife holder, a knife, a knife retaining pull down block, and a tapered draw bolt to tighten the assembly. The knife holder is constructed to engage a conventional seat in a chipper head segment. It has an arcuate front surface to receive the knife element. The knife element has a rib on its rear surface which has a dovetail or T-shaped flange. The pull down block is similarly configured with a female dovetail or T-slot to grasp the rib flange on the back of the knife holder. A tapered bolt is threaded into the knife holder and passes through a similarly tapered hole in the pull down block. As the bolt is screwed into the knife holder, the pull down block and encompassed knife element are drawn to the rear where they are tightly frictionally held against the knife holder. The knife element may have an adjusting screw which seats against an appropriate portion of the knife holder for controlling the cutting height of the knife. For maintenance it is not necessary to remove the knife holder from the chipper head segment. The knife may be removed by loosening the tapered bolt and sliding it out of the knife holder. The knife element may be simply sharpened by a conventional grinding wheel which need not be configured in any special manner. Repeated tests have shown that a knife element of the present assembly will have a life cycle approximately 30% longer than conventionally used one-piece knives.
