Abstract: The invention relates to a method of producing amorphous sample bodies that can be used for optical spectral analysis and X-ray spectral analysis, by batch-wise smelting in a crucible a mixture of analysis sample and a flux.  The method is characterized by allowing a controlled flow of molten material to run out of the crucible and successively down onto a horizontal receiving surface and there form the sample bodies.  The mixture is smelted suitably at a temperature of between 800 and 1300°C, preferably at about 1000°C, and is carried out in a crucible having a hole in the bottom thereof.  The invention also relates to apparatus for producing such amorphous sample bodies.  The apparatus includes a smelt crucible provided with an opening in its lower part and which is designed to be downwardly tapered at least inside in order to prevent the mixture from coming out, but to facilitate running of molten material through the opening.  The apparatus will also preferably include a casting plate or a mould for casting sample bodies positioned horizontally beneath the crucible. The invention also relates to the application of the method and the use of the apparatus in the production of sample bodies for the analysis of geological material, inorganic environment test material and sulfidic and/or oxidic products from ferrous and non-ferrous production processes.

Inventor: VOGT HANS-GUNTER
IPC: C08F236/12
Filed: 1997-02-25
Granted: 2005-04-19
Abstract: Latices based on conjugated dienes are produced using emulsion polymerisation by introducing the monomers to be polymerised into the initially introduced seed latex in the presence of a free-radical forming activator and an emulsifier in such a manner that the ratio of the monomer polymerisation rate to the monomer feed rate is less than 0.7:1 and by performing polymerisation up to a monomer conversion of >= 95% at temperatures of 10 to 85°C, wherein the addition of the emulsifier is controlled in such a manner that the final particle size (TG L) of the latex to be produced is governed by the following equation:        TG L = TG S × (m L/D L)1/3/(m S/D S)1/3, in which D L =  density of the latex particles in the latex to be produced D S =  density of the particles of the seed used m L =  mass of the latex particles in the latex to be produced m S =  mass of the particles of the seed used TG L = particle size of the latex to be produced TG S = particle size of the seed used.

Granted: 1999-12-07
Abstract: For accurately determining, in real time, the collapse of a thermoplastic workpiece processed in a press, such as an ultrasonic welding apparatus or a vibration welding apparatus, a two-phase method is used.  In the calibration phase signals are generated which are responsive to the yielding or displacement of the movable press portion relative to the substantially stationary portion arising from forced engagement of the workpiece within the press. The force responsive displacement value is stored.  In the subsequent workpiece processing phase, when the workpiece collapses due to the softening and flowing of thermoplastic material as the workpiece is coupled to vibrations, the previously stored force responsive displacement value is recalled as a correction signal and subtracted from the newly obtained displacement signal related to the same force.  The result of the subtraction is a true on-line signal indicative of the collapse of the workpiece as it occurs.

Abstract: A disk support bracket assembly including a cross tube bracket and a disk shank support bracket pivotally connected to the cross tube bracket to allow the disk support bracket to pivot between a working position wherein the bracket bottoms against the cross tube bracket, and a storage position wherein the bracket is offset vertically from the cross tube to increase clearance. The shank support bracket is pivotally connected to the cross tube bracket near an upper forward corner of the cross tube and includes a relatively wide stop portion that bottoms against a mating stop portion at the front face of the tube bracket when the shank support bracket is in the working position. A pin is selectively insertable through apertures in the brackets adjacent the stop to lock the shank in an upright working position. As the disk is operated in the forward direction, the load on the disk supporting shank urges the stop portions together to bear substantially all the shank loads in the stop area so that forces on the pin and pin wear are reduced over that encountered by a normal load-bearing pin.

Granted: 2002-03-26
Abstract: In a system for simulcasting digitally modulated and analog FM signals over the same FM frequency band, the effect of the analog FM signal on the digitally modulated signal in the simulcast is calculated and canceled from the latter signal before its transmission.  As a result, the digital transmission is free from interference from the analog FM signal.  Moreover, the digital transmission is achieved by adaptively inserting a time varying number of carriers modulated by digital data into the FM band. The carriers are selected frame by frame to control their interference with the analog FM signal.  In accordance with the invention, the carriers are selected in a predetermined order, and in a preferred embodiment grouped contiguously with one another in the FM band.  As a result, the rate of control information required to identify the inserted carriers to a receiver is advantageously low.
