Title: Silanes modifies par des polyols en tant que precurseurs de silice
Inventor: BROOK MICHAEL A
IPC: A61K47/48
Filed: 2003-06-02
Abstract: L'invention concerne la préparation de silice monolithique dans des conditions douces, à partir d'alcoxysilanes dérivés de sucres, d'acides sacchariques, d'alcools de sucre et de polysaccharides, parmi lesquels figurent du glycérol, du sorbitol, du mannose et du dextrane. Contrairement à ce qui se passe avec le précurseur de silice généralement utilisé, à savoir le TEOS (Si(OEt)4), l'hydrolyse par voie sol-gel et le traitement des dérivés du sucre ne sont pas très sensibles au pH, dans la mesure où des vitesses de gélification similaires ont été observées pour une plage de pH comprise entre 5,5 et 11. La morphologie des silices obtenues peut être modifiée au moyen d'additifs spécifiques, y compris des ions multivalents et des polymères hydrophiles.

Title: Sequential correlator for spread spectrum communication system
Inventor: CRIPPS PETER K
IPC: H04L9/12
Filed: 1989-12-13
Abstract: Abstract A spread spectrum communications system includes a spread spectrum encoder wherein the input data signal is combined in an exclusive OR gate with the output of a digital function generator connected in a feedback arrangement which encodes an input data signal with a spreading code sequence.  In general, a digital function generator provides an output signal, which after a predetermined time, is a predetermined function of the prior input to the digital function generator.  At the receiver, the data is recovered in a spread spectrum correlator using a similar digital function generator and an exclusive OR gate, but connected in a feedforward arrangement.  The correlator, using the digital function generator in a feedforward configuration, performs the inverse operation of the encoder, which uses the digital function generator in feedback configuration, in order to recover the data.  A spread spectrum system embodying the present invention will synchronize after a predetermined number of chip clocks have elapsed, sufficient to cause the respective digital function generators in the encoder and correlator to each provide an identical predetermined output pattern.

Abstract: ABSTRACT OF THE DISCLOSURE    A gas analyzer (10) for detecting low concentrations of a specific gas which has a sample chamber comprising passages (14, 30, and 32) through which radiant energy is directed and which is pressure modulated by a loud speaker (36) both of which provide a radiant energy signal which is detected by a beam splitter (82) having a measurement channel (86) directed to a measurement detector (92) and a reference channel (84) with a reference cell (94), containing gas of the type being analyzed, directed to a reference detector (90).  Both detectors (92, 90) produce a signal which is processed by an algorithm. The loudspeaker (36) is isolated from the sample chamber by a flexible diaphragm (42) to eliminate phase changes in the pressure modulated output of the loud speaker (36).  Means are provided for measuring the modulation or AC pressure ant the steady state or DC pressure in the sample chamber, the radiant energy modulation, the humidity in the sample chamber and the temperature of the analyzer as parameters for processing by the algorithm.

Abstract: A method of removing a binder from a green body capable of   accomplishing the binder removal at a substantially reduced temperature and in a significantly reduced period of time.  The binder mainly consists of a polymer material of ultraviolet degradation properties such as, for example, a polymer material having a main chain containing a tertiary carbon atom.   The green body is irradiated with ultraviolet rays at a temperature within the range of 150°C to 300°C  under an atmospheric pressure to rapidly carry out the photo degradation of the polymer material by ultraviolet rays, so that the binder may be readily removed from the green body.

Title: Attachment elements
Inventor: HOFFMAN ARMIN
IPC: F16B13/14
Filed: 1990-04-17
Abstract: ABSTRACT OF THE DISCLOSURE         Attachment elements to be fixed to panel-shaped structural components by a hardenable material including an axially elongated dowel sleeve with a passageway extending from a second end toward a first end.  Apertures in the dowel sleeve open from the passageway to the exterior of the sleeve.  An axially extending annular part encircles the dowel sleeve.  A bag-like member is secured to the annular part and to the dowel sleeve adjacent the first ends thereof.  The bag-like member is positioned so that it is located on an inner side of the structural component after the attachment element is inserted through a borehole in the structural component from an outer side thereof.  The bag-like member can be filled with a hardenable material providing a gripping action with the inner side of the structural component.     The bag-like member, when filled with the hardenable material, has a first side facing the inner side of the structural component and an oppositely facing second side.  The bag-like member has openings in the first and second sides with the openings in the first side being larger than the openings in the second side.  As a result, when hardenable material is injected into the bag-like member, it flows out through the openings in the first side and supports the bag-like member with large area contact with the inner side of the structural component.  Therefore, high anchoring values are achieved with this larger area support.
