Inventor: GRAFF PIERRE
IPC: B31F1/07
Filed: 2008-08-06
Abstract: The absorbent crepe paper has at least one embossed pattern (14,16) which projects from the paper base (12). It has an initial set of projections (22) in a general stump shape which protrude on one surface (13) in the structure of a decorative design. The paper (10) has a second set of projections, positioned with the first set (22), as a low wall (24) from the paper surface (13), at a lower height than the first set (22) of projections, to give a dimensional view of the total pattern (14,16). The first set of projections (22) form a pattern of closed loops (14,16). Two consecutive sets of projections (22) are linked by the second set (24), as low walls joining them together. The figures form at least a partial arc. The sets of projections (22,24), together, form a variety of concentric closed loops. The paper has a number of layers, developed from a cellulose pulp, where at least one is an embossed and patterned layer (10), or each layer is embossed with a pattern. The relief pattern is on the inside of the outer paper layer. Where the paper is in two layers, the embossed surfaces face each other to be locked by their relief patterns. An Independent claim is included for a paper embossing cylinder with a profiled surface to give the embossed pattern in two sets of different heights.

Title: Quality control methods for oil-in-water emulsions containing squalene
Inventor: KLEIN NORBERT
IPC: A61K39/00
Filed: 2007-11-06
Abstract: Measurements of the squalene content in oil-in-water emulsions can be used as a way of checking for problems during production. In particular, it has been found that a drop in squalene content can indicate that filtration problems occurred. Testing the squalene content in the final lots is easier than investigating the characteristics of the filter, and so a squalene assay simplifies the quality control of oil-in-water emulsions.

When seeking a target address on a record medium (1) on which the recorded data are divided into a plurality of blocks in correlation with an address for each block and an error check code for each address, the error check code to be appended to the address is formed from the target address. The target address and the error check code derived from the target address are compared with the address having the error check code reproduced from the record medium (1). When the result of such comparison has revealed that the error is within the symbol or bit number that can be corrected by the error check code, the address read from the record medium (1) is determined to be the target address.

Abstract: Oxidation of alcohols to ketones using bromine suffers from a side reaction of comparable speed in which a bromide substituted product is formed. Additionally, the use of bromine as reagent is relatively unpleasant and it creates a major waste disposal problem. The latter problem can be solved by generating bromine in situ by reaction between hydrogen peroxide and bromide ions or hydrogen bromide, but this inevitably increases the exposure of the alcohol to HBr/Br<->. The selectivity of the process towards non-substituted oxidation depending upon the inherent deactivation or reactivity of the alcohol can be improved by irradiating the reactants with light of suitable frequency to generate bromine radicals in the mixture, and/or by controlling the rate of introduction of the hydrogen peroxide and controlling the extent to which mole ratio of HBr:alcohol is substoichiometric. Selectivity can also be improved by employing a two-phase reaction mixture, the alcohol being present to a considerable extent in the organic phase with HBr/Bromide being retained to a great extent in the aqueous phase. It is particularly beneficial for the selective oxidation of alcohols that are substituted by adjacent electronegative groups, for example chloropropanols.

Abstract: A process for bonding silicon die (10) to a package. This process comprises the following steps: (a) providing to the back surface of the die (12) an adhesion layer (14) of material which exhibits superior adhesion to both the silicon die and a subsequently applied barrier layer (16); (b) providing to the adhesion layer (14) a barrier layer (16) which is impervious to silicon; (c) providing to the barrier layer (16) a bonding layer (18); and (d) bonding the die to the package by activating a binder composition disposed at the interface of the package and the bonding layer. The barrier layer prevents the migration of silicon to the bonding layer, both at the time of application of the bonding layer to the die and at the time of bonding the die to the package. The adhesion layer enhances the adhesion of the barrier layer material to the back surface of the die. Titanium is the preferred adhesion layer material while tungsten is the preferred barrier layer material. The bonding layer preferably comprises gold while the preferred binder composition is a gold-tin alloy solder. The enhanced adhesion of the barrier layer which prevents silicon migration into the gold produces highly reliable bonds. In another embodiment, a stress relief layer is interposed between the adhesion layer and the back of the silicon die. The material of the stress relief layer is alloyed to the silicon at the back surface of the die which relieves stresses in the die and enhances the planarity of the back surface. This produces bonds which exhibit superior electrical and thermal contact characteristics.

Abstract: Ultrasonic vibrations indicating trouble at remote locations are detected by sensors (20) spaced in the vicinity of expected trouble. These sensors have weather resistant transducers that convert ultrasonic vibrations from a leak in a conduit, electrical arc, bearing vibration or the like, into an electrical signal. In the sensor there are circuits that amplify the electrical signal and transmit it with a current loop transmission system over a twisted pair of wires to a central control and analysis computer (30). The amplification of the signal at the sensor is controlled by a signal from the central computer which changes the gain increments until the sensor circuits are not saturated by the ultrasonic signal. This gain control signal is also delivered to the sensors over a twisted pair of wires (31, 33) by current loop transmission system.
