The parasol has a tubular section (22) at the lower end with in internal shoulder at its lower end. The end of the string (25) is attached to a rigid, metal stop (35) which is sufficiently long to allow it to rest against the shoulder in the tubular section (22) which it is placed crosswise on the string. The width of the stop is narrow enough to allow it to pass through the tubular section. The r...

A system for protecting premises against a certain condition, comprising a sensor (13, 14) for providing an output signal upon sensing such condition, an alarm unit (17) for providing an alarm signal when armed and upon receipt of the output signal from the sensor (13, 14), and a timer (25) coupled between the sensor (13, 14) and the alarm unit (17) which timer (25) counts down from a preset count...

This invention is related to the production and application of heat-shrinkable films derived from a mixture of styrene - butadiene copolymer and polyolefin type resins produced by any of the known processes for polymeric films production. Thermal and mechanical properties of the films derived from this invention makes them suitable to be used, among other applications and with no restriction to th...

Solid elastomeric gel is produced in a continuous process using a twin screw extruder (10). Gel from the extruder (10) can be fed through a die (21) to form a length of the gel (20) with a uniform cross section and then cut to length to provide pieces of the gel (20) for use in a pad. Alternatively, gel from the extruder (10) may be injected into a chamber between a rigid base portion and a thermo...

Water-soluble film, suitable for sachets, comprised of a combination of soft and hard acid-functional polymers having Tg's of /= 40 DEG C respectively, the polymers being at least partially neutralised and present in a weight ratio (soft to hard polymer) within the range 90/10 to 65/35. Sachets made from the film are particularly suitable for packaging agrochemical and laundry care co...

Die Erfindung betrifft ein Verfahren zur Wiederaufarbeitung von ausgehärteten oder teilweise ausgehärteten Polysulfid- und/oder Polymercaptan-Zusammensetzungen. Die Aufarbeitung erfolgt in einer nicht flüchtigen Flüssigkeit unter Zusatz eines Depolymerisationsmittels, vorzugsweise eines aus der Kautschuk-Technologie bekannten schwefelhaltigen Vulkanisationsbeschleunigers. Das Depolymerisat kann in...

The invention herein is a non-aqueous solvent free process for producing UV curable adhesive and sealant compositions comprising a tackifying resin and a monohydroxylated epoxidized polydiene polymer which is comprised of at least two polymerizable ethenically unsaturated hydrocarbon monomers wherein at least one is a diene monomer which yields unsaturation suitable for epoxidation and wherein the...

The system includes a light source which produces three primary rays of light (FC,FD,FG) which have parallel optical axes and focus at three distinct points in a plane parallel to a disc. A diffraction system diffracts the central ray into three rays (FC1,FC2,FC3) according to orders of diffraction (-1,0,+1). Triple diffraction is performed on the lateral rays. Phase adjustment of the primary rays...

The present invention concerns a process for manufacturing conductive diamond layers, in particular layers of diamond doped with boron which are obtained by chemical vapour deposition (CVD). The process of the invention consists of forming a layer of diamond doped with boron using amino-borane compounds. These boron compounds are of particular interest since they are non-toxic and easy to manipula...

A very high-level, bidirectional protocol (CP) is used for communication between a hyper-media system (HS) and a plurality of interconnected editors (HSE, Ea, Eb, Ec, etc.) communicating in a hyperstructure. This protocol (CP) uses a set of messages allowing each editor to manipulate and manage the contents of hypermedia objects, called nodes, and it is, furthermore, manipulated by the hypermedia ...

Le dispositif (1) comporte, de manière classique, des moyens (3 à 6, 15) pour exciter une première vibration de son transducteur (2), des moyens (7 à 10) pour produire un signal de détection (SD) de la deuxième vibration de ce transducteur (2), et des moyens (18) pour produire un signal (SM) de mesure de la vitesse angulaire du transducteur (2) en réponse à cette deuxième vibration.
