Title: Hydraulically actuated indexing mechanism
Inventor: HORSCH JOACHIM
IPC: F01B1/06
Filed: 1989-01-04
Granted: 1993-01-05
Abstract: ABSTRACT OF THE DISCLOUSRE:        An indexing mechanism comprising a member adapted to be advanced a predetermined amount and along a predetermined path, a pair of spaced drivers, and a control valve for operating the drivers in an alternative manner.  The member adapted to be advanced defines a profile surface including a plurality of spaced radial segments.  Each radial segment includes a crown section which is joined to an adjacent crown section by two oppositely directed ramps defining a fillet radius therebetween.  The spacing between the drivers being such that when one driver is urged against a crown section the other driver acts against a fillet radius.  The drivers are operated by the control valve 180° out of phase relative to each other.  A driver, after moving off a crown section, coacts with a ramp to impart a driving force to the member.  The driving force being sufficient to move the member in an indexed fashion the predetermined amount of its movement.

Abstract: Title:  A method of, and apparatus for, leak testing a package ABSTRACT    A method of, and apparatus for, leak testing a package, in which the package (6) is placed in a sheet-like, gas-tight envelope. A pressure differential is generated between the outside and the inside, as a result of which the package is closely enveloped by the envelope. This pressure differential is so large that it decreases the volume of the package and increases the internal pressure in the non-filled portion thereof. In the space (16) ("measuring space") between the package and the envelope pressed against it, a pressure is used which is lower than the increased pressure in the package. In the sealed measuring space, the change in pressure is measured for a pre-determined measuring period.

Abstract: ABSTRACT  A method is described for collecting, from  the  water, oily  matters  and  wastes  in general, floating  on  the  surface  thereof,  which  comprises separating,  from  the  lower  layers,  a  surface  waste containing  layer,  subjecting  the  same  to  subsequent concentration operations of said wastes and ejection of the underlying water. An apparatus for practising such method comprises a floating structure having good sea-worthiness qualities,  adapted to be disassembled in a number of parts, provided with means for separating a thin surface layer bearing the whole amount of wastes, and for introducing them in a large movable decantation basin adapted to follow the major wave motion, with decanted water ejecting means, with means for transferring liquid bearing already concentrated oily matters to a system of tanks  communicating  with  each  other  for  further decantation and final separation of oil from the water, and  with  means  adapted  to  hinder  the  internal  wave motions. The apparatus does neither require continuous personnel  attendance  on board  nor  interruption  of operations  during  unloading  of  the  collected oily wastes.

Abstract: Abstract Preparation of Epoxy Nitrates A method of preparing a nitrate ester of an epoxy alcohol, which consists of reacting an epoxy alcohol with N2O5 in an inert solvent at a temperature of -10°C to-40°C, followed by quenching the reaction mixture  in aqueous  solution.  Quenching separates the nitric acid and nitrate ester coproducts into aqueous and organic phases respectively to prevent subsequent reaction between the two. Reaction between the nitric  acid  coproduct  and  epoxy  alcohol reagent to produce acyclic contaminants is supressed by adding the epoxy alcohol to excess N2O5, thereby rapidly converting available alcohol to nitrate ester.

Abstract: Abstract A clutch and brake apparatus operable by a compressible fluid, partic-ularly pneumatically, comprising input (1) and output (2) shafts mounted in a common housing (2, 4) is desoribed, wherein a clutch flange (5) fixed to rotate with the input shaft and a clutch plate (6) are disposed in the clutch chamber (11), and the clutch plate (6) subdivides the clutch chamber (11) into two operating chambers (9, 10) adapted to be at different pressures and can be applied to the clutch flange (5) with an interposed friction lining (7, 8) or to an end face (26) of the clutch chamber (11).  In this construction, there used to be the problem that only a limited torque could be transmitted because the clutch plate had to be bent out so as to make contact with the individual friction faces.  For higher torques, the pressure in the operating chambers had to be increased so that the clutch plate was subjected to impermissibly high stresses.  The new apparatus is to be able to operate with a large pressure difference across the clutch plate without the danger of damaging the clutch plate.  For this purpose, the clutch plate is mounted to be slightly axially displaceable relatively to the output shaft in every load condition, at least one axially non-rotatable torque plate is fixed to rotate with the output shaft and the circum-ference of the clutch plate, and the torque plate is subjected to the same pressure on both sides.
