Filed: 1991-09-24
Abstract: 2094918 9207791 PCTABS00013 Conventional plant to produce peroxomonosulphuric acid (Caro's acid) is large and emphasises extensive cooling, so that it is awkward to transport, can be cumbersome to install beside existing plant and can suffer from relatively expensive capital and/or running costs. In the present invention, Caro's acid is generated continuously in relatively small plant adiabatically, by introducing concentrated hydrogen peroxide (8) into a stream of concentrated sulphuric acid in a reaction chamber (5) dimensioned so that the throughput is very fast. In particularly suitable embodiments, the reaction chamber is annular at the points of introduction of the reagents, its width being greater in the vicinity of the hydrogen peroxide inlet than in the vicinity of the sulphuric acid inlet (7). The hydrogen peroxide inlet (8) is preferably angled backwardly so that its encounter angle with the sulphuric acid stream is over 90 to about 165·.

Title: Process and arrangement for testing bottles for contamination
Inventor: GYSI PETER
IPC: G01N35/04
Filed: 1993-07-06
Abstract: ABSTRACT OF THE DISCLOSURE           For testing bottles in particular by mass spec-trometric analysis, gas samples are removed simultaneously from several bottles by means of probes.  The gas samples are fed in succession and in a predetermined sequence to a mass spectrometer by a distributor unit. In this way, a single mass spectrometer is sufficient for testing a number of bottles thus substantially reducing costs in terms of money and maintenance and calibration time.

Title: Varying Tone Security Document
Inventor: MOWRY WILLIAM H JR
IPC: G03C5/08
Filed: 1993-12-30
Abstract: An improved security document according to the present invention includes a substrate having a surface for carrying indicia.  The document has background printed matter, consisting of a pattern of elements of a first size and frequency, printed at a first density on the surface.  The document further has a cancellation term, consisting of a pattern of elements of a second size and frequency, printed at a second density on the surface.  Elements of one of the first size or the second size are sufficiently small such that they are not reproduced by a color copier at a particular copier setting, and elements of the other of the first size or the second size are sufficiently large such that they are reproduced by the color copier at the particular copier setting.  As a result, a copy of the security document made on a color copier displays the cancellation term. At least a portion of the security document surface is divisible into a plurality of bands extending across the surface.  The sizes of the elements and the density of the background printed matter and the cancellation term vary together across the bands in a direction generally normal to the bands.  As an alternative, the frequencies of the elements may vary across the bands such that the density of the background printed matter and the density of the cancellation term are changed.  Such a document may be printed with different colors of ink on different portions of the document, and with the bands in which a color transition occurs being printed with two colors of ink at differing screen angles.

Title: Trellis coding in a simultaneous voice and data system
Inventor: BETTS WILLIAM L
IPC: H03M13/01
Filed: 1994-06-09
Abstract: Abstract of the Disclosure A communications system simultaneously transmits both a primary data signal and a secondary voice signal in such a way that the dynamic range of the secondary voice signal is increased even though deliberate errors are introduced into the transmitted data portion of the signal. In particular, the communications system includes an error correcting technique like channel encoding and the constellation signal space is divided into a number of regions, where at least one of the regions overlaps with another region. The primary signal is channel encoded to select a particular one of the number of regions, the region being represented by a reference signal point value. The voice signal is encoded to provide a signal point vector, which is added to the reference signal point in such a way that the resultant signal point is located in the overlapping region thereby deliberately introducing an error into the resulting transmitted signal point stream. Notwithstanding the deliberately introduced error, the channel encoding of the primary signal allows a receiver to recover the originally selected reference signal point value, which when subtracted from the received signal point value approximates the voice signal.

Patent CA-2128158-A1 (CA)
Inventor: HAGMANN PETER
IPC: C08F16/06
Filed: 1994-07-15
Abstract: A measured amount of a material that is crosslinkable by impingement of a suitable form of energy, especially UV light (3), is introduced into a two-part mould (1) of which the cavity (15) determines the shape of a moulding (CL) to be produced. The two mould halves (11, 12) are held a small distance from one another so that a thin annular gap (16) is formed between them, which gap is in communication with the mould cavity (15) and through which gap excess material can escape. The crosslinking is triggered by impingement of the selected form of energy, the impingement being spatially restricted to the cavity (15) by suitable moulding (21) so that material disposed outside the mould cavity is not crosslinked.  In that manner mouldings are obtained that do not require subsequent mechanical processing, and the mould is reusable. The process is especially, but not, however, exclusively, suitable for the manufacture of contact lenses.

IPC: B01J13/12
Filed: 1993-07-16
Abstract: The present invention relates to a highly efficient method of preparing modified microcapsules exhibiting selective targeting.  These microcapsules are suitable for encapsulation or surface attachment of therapeutic and diagnostic agents. In one aspect of the invention, surface charge of the polymeric material is altered by conjugation of an amino acid ester to the polymer, providing improved targeting of encapsulated agents to specific tissue cells.  Examples include encapsulation of hydrophilic radiodiagnostic agents in 1 µm capsules to provide improved opacification and encapsulation of cytotoxic agents in 100 µm capsules for chemoembolization procedures. The microcapsules are suitable for attachment of a wide range of targeting agents, including antibodies, steroids and drugs, which may be attached to the microcapsule polymer before or after formation of suitably sized microcapsules. The invention also includes hydrophilic microcapsules surface modified with hydroxyl groups. Various agents such as estrone may be attached to the microcapsules and effectively targeted to selected organs.
