Abstract: ABSTRACT Hydrogen Peroxide Solutions It would he desirable to replace nitric acid based solutions for surface treating steels and like materials with a sulphuric acid based solution containing hydrogen peroxide, but such replacement solutions lose hydrogen peroxide rapidly through mainly iron-induced decomposition.   A surface treatment solution that is based on sulphuric acid and hydrogen peroxide, but has improved stability, contains as stabiliser system an effective amount in combination of hydrofluoric acid, an hydroxybenzoic acid and an N-alkoxyphenyl-acetamide.   Preferably, the hydroxybenzoic acid is para-hydroxybenzoic acid and the N-alkoxyphenyl-acetamide is N-(4-ethoxy-phenyl)-acetamide.  It is preferable to employ a saturated solution of each of the two latter components, and this can achieved practically and simply by adding the solid components in the shape of a block or blocks which maintain the saturated solution over an extended period of time.   136xp-can

Abstract: LOADED SHOTGUN SHELL TESTING  APPARATUS USED TO VISUALLY      INSPECT, VIA TRANSMITTED LIGHT IMAGES, THE INTERNAL      ARRANGEMENT OF THE POWDER, WAD. AND SHOT                          ABSTRACT      Shotgun shell testing apparatus positions a loaded shotgun shell in the path of a light source.  An observer, generally a shooter, places his or her supposedly properly loaded shotgun shell in a receiving space of this apparatus and turns on the lighting energy source. By observing the resulting internal derived image of the fiber derivative portions of the shell casing, often observable at the exterior of the apparatus, and comparing this image observed with the likeness of an earlier image reflecting a properly loaded shotgun shell of the specified power charge, a shooter is able to determine if the shotgun shell being tested, via this observation, has been correctly loaded in respect to the positioning of the powder, wad, and shot.

Title: Process of preparing rhodium nitrate solution
Inventor: ICHIISHI SATOSHI
IPC: B01J23/46
Filed: 1992-03-19
Abstract: Abstract of Disclosure Disclosed herein is a process of preparing a rhodium nitrate solution which comprises reacting rhodium hydroxide with nitric acid characterized in that the mixed solution of the rhodium hydroxide and the nitric acid is concentrated under heating.      Rhodium nitrate prepared by a conventional method which comprises dissolving the precipitate of rhodium hydroxide which has been prepared by dissolving rhodium black in concentrated sulfuric acid under heating and controlling pH possesses low supporting efficiency on a support for preparing a catalyst.      When the mixture of the rhodium hydroxide and the nitric acid is concentrated under heating according to the present invention, the conversion of the compounds conjecturally formed at an initial stage of the reaction into the desired rhodium nitrate is considered to be accelerated to prepare the rhodium nitrate solution with high purity by the above concentration under heating of the mixture of the rhodium hydroxide and the nitric acid, and the supporting efficiency of the rhodium nitrate to the inorganic support can be improved to about 99%.

Title: Compact torque limiting clutch
Inventor: HEIDENREICH DAVID C
IPC: F16D7/02
Filed: 1992-07-15
Abstract: ABSTRACT A compact torque limiting clutch provides spring cup bolt assemblies for interengaging a pressure plate and input flange on opposite sides of a friction flange of an output hub. The spring cup assemblies include bolts employed for securing the clutch elements together, such bolts being restricted from rotatingduring the assembly process by engagement with noncircular apertures passing through the retainer plate. The torque limiting clutch is of a pancake design, contained between axially displaced planar surfaces defined by an input flange on one side and a pressure plate on the other. In another embodiment of the invention, a keeper plate is coaxially secured to an output hub, with a friction disc fixedly secured therebetween. An input drive flange is rotatably mounted on the keeper plate. A separator disc extends the full diameter of the clutch assembly and has cup-shaped shields extending therefrom, serving as seals and heat dissipating members. Torque pins pass through a pressure plate which is urged toward the input hub by a plurality of spring cup bolt assemblies, the torque pins serving as indicators of clutch wear.

Abstract: An adjustable control valve for flow regulation of gas or liquid has a controlled hose clamp device, preferably with two clamping members (K1, K2) disposed on respective sides of a hose (A) for adjustable compression of the hose and thereby setting of the flow cross-section of the hose at a compression site between the clamping members. The control valve comprises further a movable cam disk, e.g. a rotatable eccentric sheave (E), actuated by a shifting mechanism, preferably a step motor, disposed for variable compression of the hose in accordance with the position of the cam disk or eccentric sheave. For automatically controlled setting of the flow cross-section of the hose, the shifting mechanism may be arranged to be controlled from measuring means mounted for gauging the flow in the hose (A) downstream of the compression site (As). In practice such regulation may be used for controlling the quantity ratios between the supplies of paint, jet formation air and atomizing air, respectively, to an atomizing gun (P), preferably by means of a common data processing unit (D) inserted between the control valve (Sa, Sp, Sf) and measuring means (Ma, Mp, Mf) in all control loops (Qa, Qp, Qf) for the supplies of paint, jet formation air and atomizing air, respectively, to the spray gun (P).
