The shutter in question comprises three elements, a central translucent element (1) made of synthetic resin, for example of polycarbonate, with a plane external surface (AB) and a concave internal surface (CD) to reduce bulkiness during rolling. The upper element (2) and the lower element (3) are made of metal, preferably of oxidised aluminium, and can be threaded in with a dovetail joint at the e...

A method is disclosed for the deposition of vanadium oxide films on glass substrates, as well as a thermochromic VO2 film for the variable transmittance of solar energy and a conductive V2O3 film, both formed by chemical vapour deposition employing liquid vanadium compounds. Doping of thermochromic vanadium oxide films to lower the transition temperature is also disclosed.

The drive for a self propelled device which can be based on the design of a skate board or scooter includes a spring which transfers shock forces to the drive so as to assist it. Between a base and a foot support is a helical spring at the pivot end and a belt drive at the front end. The base has wheels attached at front and rear. Pressure on the foot support drives the belt, and this is assisted ...

PURPOSE:To prevent an accident of collision from behind at running of a vehicle, by transmitting an ultrasonic wave signal toward the front of an automobile, receiving its reflected wave, detecting a distance between cars and automatically applying a brake when the detected distance reaches a hazardous distance. CONSTITUTION:A device is constituted in such a manner that plural sets of ultrasonic o...

New optically active bis phosphine compounds which are useful in optically active catalysts. Such catalysts are particularly useful in catalytic asymmetric hydrogenation.

The dispensing container is provided for substances whose minimum viscosity at room temperature is 10,000 cps, but can rise to 500,000 cps or more. It has a pressure container with a dispensing valve (15). To open the dispensing valve, a hollow valve shaft (22) is pivoted in an elastic valve body (23). As a result, an aperture (32) is produced on the valve seat (26), through which aperture the sub...

A fluid bed reactor includes an integral flow circulator which eliminates the need for recirculation equipment external to the reactor and permits utilization of multiple distributor modules to provide a wide range of reactor capacities.

The apparatus feeds products in mutually spaced relation to a work station such that successive products are received thereby at substantially the same point of successive working cycles. The apparatus comprises a first conveyor arranged to receive a longitudinal row of products in which adjacent products are touching, and a second conveyor receiving products from the first conveyor and driven at ...

Apparatus for feeding articles arranged in a row from an intermittently driven metering conveyor (MC) to the lugs of an infeed conveyor (1c) for feeding the articles to a wrapping machine comprises opposed endless conveyors (212, 214) rotated in a common horizontal plane to grip the articles therebetween and so to transfer the articles from the metering conveyor to the infeed conveyor. At its upst...

A valve assembly for a container for pressurized fluid in which a cup (10) mounts the assembly to a container body, and a valve (14) including a valve housing (12) fitted in the cup, the valve housing is located within the cup by the engagement of internal projections (16) in the cup behind a head (18) of the housing. The cup, the valve housing (12) and the valve (14) are arranged in one condition...

A high temperature non-conducting inorganic refractory adhesive suitable for use in conjunction with a number of substances including conducting elements metallic in nature.

Platinum-catalyzed mixtures of H(CH3)2SiO-(C6H5)2SiOSi(CH)2H and monophenylsiloxy/dimethylvinylsiloxy copolymer cure to give a strong flexible resin having thermal shock resistance.

There is provided flame retardant thermoplastic compositions and masterbatch formulations effective for rendering thermoplastics flame retardant. A typical flame retardant composition could be comprised of 50 to 97 percent by weight of thermoplastic, 1 to 40 percent of a silicone base such as a linear silicone fluid or gum, 1 to 20 percent of a metal organic compound such as magnesium stearate, an...

PURPOSE:To prevent the slack of a wire by a method wherein a sleeve through which the wire leads is provided between a loewr clamp that holds the wire led out of a wire delivery device and a bonding tool, and closely to them. CONSTITUTION:A wire 3 that is led out of a wire delivery device 2 is led in a clamp device through a wire guide 4, and then in a bonding tool 22. A sleeve 19 is provided betw...
