Abstract: A b s t r a c t :            "Device for the control of an ammonia converter etc,"          By means of a device for controlling an ammonia converter etc., with process gas inlet and outlet, at least one heat exchanger and at least one catalyst bed as well as another gas supply line and a central pipe as well as a process gas supply line to the heat ex-changer or, respectively, the catalyst bed, with the heat exchanger placed in a dynamically balanced position with regard to the cen-tral pipe, while the catalyst bed is likewise placed in a dynam-ically balanced position around the heat exchanger, a solution is to be provided which allows the feeding into the respective gas streams of control gas, quench gas and part of the process gas at various temperatures and/or under various conditions at any place of a reactor, the solution to be adopted being such that the admix-ture or, respectively, the bypass line can be fully shut off or partly opened or, respectively, fully opened.            The solution is effected in that, for temperature control purposes, the central pipe (14), being the control gas feedpipe, runs through the entire length of the heat exchanger (a or, respectively, 5 or, respectively, 6) and is fitted, at the latter's bottom end, with adjustable outlets (18) to allow at least partial admixture of con-trol gas to the process gas stream before the latter passes through the catalyst bed (4), or, respectively, to allow admixture of the control gas stream to the process gas stream after the latter has passed through the catalyst bed (4) and the heat exchanger (7).

Title: Emergency descending device
Inventor: ISHIOKA SHIGEO
IPC: A62B1/14
Filed: 1987-12-24
Granted: 1992-10-27
Abstract: ABSTRACT OF THE DISCLOSURE     An emergency descending device comprising a rotary wheel and a cam mounted between a pair of side plates, with a main rope passing between the rotary wheel and the cam.  The rotation of the rotary wheel caused by the main rope generates a centrifugal force on a brake shoe, and the brake shoe tends to rotate a brake drum.  The rotation of the brake drum rotates the cam toward the rotary   wheel   thereby   clamping   the  main   rope therebetween,   and  suitable  descending  speed  can  be obtained.

Abstract: ABSTRACT      A system for making a long length of seam-welded tubing from shorter lengths of flat metal strip which are spliced end-to-end and formed into tubular form and seam-welded.  Adjoining ends of two successive lengths of the strip are trimmed at supplementary angles, one of which is an acute angle.  The trimmed ends are abutted and welded, preferably with weldment extending beyond each such end. All surfaces of the weld are finished to match the dimensions of the strip.  The tubing, along with the welded joints, is heat treated as the tubing is formed to produce a product substantially free of internal surface roughness along the splice welds.

Abstract: An internal combustion engine having a sleeve valve wherein the sleeve valve is the cylinder sleeve of a respective cylinder whereby a very simple reciprocation and oscillation of the sleeve valve may be effected by means of a rotary valve which controls the intake of a fuel-air mixture into the crankcase of the engine.   By supplying the fuel-air mixture into the crankcase of the engine and providing each cylinder with transfer passages extending axially through the cylinder and radially adjacent cooling  fins  of  such cylinders,  it  is  possible to effect an isothermal compressing of a fuel-air mixture within the cylinder followed by that fuel mixture being adiabatically compressed by the movement of the respective piston towards the head.  The use of a sleeve valve, particularly in association with rotary intake valves, provides for a very simple valving arrangement with a minimum of parts.  Two such engines may be mounted in shaft-to-shaft relation and simultaneously drive coaxial shafts in opposite directions to provide for counter rotating propellers for an aircraft.   The engine construction provides for a maximum power output with a minimum weight.

Granted: 1993-03-23
Abstract: MEDICAL GUIDEWIRE                         ABSTRACT    A medical guidewire has an elongated body that has a degree of flexibility and a distal tip region of relatively greater flexibility.  The guidewire consists of a core having a body of first diameter, a distal portion of a relatively smaller diameter, and a generally flat distal end.  The end is disposed in the tip region and is spaced proximally from a round tip element that defines the distal end of the guidewire.  A first coil is joined to the core body and extends along the core to a termination point in the distal tip region, proximal of the end of the core.  A relatively more flexible second coil is joined at its proximal end to the first coil and joined at its distal end to the round tip element.  A safety wire is secured to the core and has a generally flat distal end within the second coil, joined to the round tip.  A transition wire is secured to the core and has a generally flat distal end that terminates within the second coil intermediate of the distal ends of the core and safety wire.  In this or other medical guidewires, the first and second coils are joined in sequence, the second coil overlapping the first coil, both having essentially the same outer diameter. The above resulting in a joint of substantially uninterrupted flexibility.

Abstract: A broaching tool has a needle-shaped working portion (2) and a shank portion which is shaped for attachment in the distal end (18) of a drive bar (12) of a drive instrument for the tool. The shank portion of the tool has at least one bend (8) and preferably also a second oppositely directed bend (10). A proximal end (14) of the drive bar (12) of the drive instrument is adapted to be coupled to a vibratory element (16) which, thereby, is able to generate longitudinal high frequency vibrations in the drive bar (12). The distal drive bar end (18) is angled (B) about an axis (22) which acts as a hinge having a certain rigidity of bending. By adapting and matching a. o. the angle (B) and the bends (8, 10) in the tool, it is possible to compensate away distructive natural oscillations in the tool which, thereby, can be powered and used with high working frequencies without risk of fatigue fractures in the material of the tool.

Abstract: Aqueous bleaching agent suspensions based on a water-soluble peroxycarboxylic acid suspended in a carrier liquid in the presence of an organic thickening agent and of an acidifying agent exhibit an improved storage resistance over known suspensions with this base. This is achieved by means of pourable to pasty bleaching agent suspensions which contain a xanthan polysaccharide or agar polysaccharide as thickening agent and, in addition, a hydrate-forming neutral salt which desensitizes peroxycarboxylic acids. Preferred suspensions exhibit a pH of 2-5 and contain 10-30% by wt. diperoxydodecanedioic acid, 5-20% by wt. sodium sulfate and 0.1-1.0% by wt. xanthan. The use of non-dried, hydrophilized and optionally in situ desensitized peroxycarboxylic acids is especially preferred. The bleaching agent suspensions are prepared by homogeneously suspending the peroxycarboxylic acid in the thickened carrier liquid. The storage-resistant bleaching agent suspensions are used as laundry bleaching agents and for preparing cleaning agents and disinfection agents.
