The density of successive increments of a cigarette rod is measured by an apparatus which employs one or more photocells operating with ultraviolet, infrared or visible light. The radiation source of each photocell emits a beam of ultraviolet, infrared or visible light which penetrates through the wrapper and the filler of the rod and thereupon impinges upon one or more transducers which transmit ...

A remote control system for a mobile object, comprising radio beacons each consisting of a master station and some substations, a mobile communication station mounted on each auto-pilot mobile for receiving the radio wave, such as millimetric, from each radio beacon, to let the mobile recognize its own position on the route map, and a control station for transmitting and receiving signals by radio...

Premixes of a polyol suitable for polyurethane or polyisocyanurate foam preparation and 1,1-dichloro-1-fluoroethane require no stabilizer to inhibit reaction between the fluorocarbon and the polyol. These premixes are useful for polyurethane and polyisocyanurate foam preparation.

A system for allowing an automatic guided vehicle (AGV) to move from a first guided area to a second guided area across an unguided span that separates them. A first guidance structure such as a buried cable is displaced from a second guidance structure. A communications and traffic controller is connected to each of the first and second guidance structures. Also connected to the communications an...

PURPOSE: To make speed compensation unnecessary by providing an optical inspection system whereby the operating speed of a transportation system for work pieces having no necessity of readjustment of the work piece inspection system is changed. CONSTITUTION: A scanning head 8 contains a proximity detector 6 united for responding to the positioning of the end part 2 of a rotatable circular can adjo...

PURPOSE:To prevent liquid crystal from being contaminated by using a seal in a closed loop shape for the empty panel and partitioning a space where liquid crystal is charged and a projection part projecting from part of the liquid- crystal charged space. CONSTITUTION:The seal 3 is in the closed loop shape and partitions the liquid- crystal charged space 34 of 5mum in gap thickness (g) and the proj...

An electrosurgical generating system including an electrosurgical generator; a handpiece including an active electrode connected to the generator for applying electrosurgical current from the generator to a patient; and an initializing device or circuit for making an initial determination as to whether the handpiece includes power changing switches for changing the level of the output power delive...

La présente invention a pour objet un siège articulé, du type "flaneuse", remarquable notamment en ce qu'il s'adapte automatiquement à la position prise par l'usager, ledit siège passant progressivement de la forme "fauteuil" à la forme "chaise longue", lorsque l'usager passe de la position "assise" à la position "couchée" en passant par toutes les positions intermédiaires. Dans toutes ces positio...

For seismic monitoring of a petroleum deposit at least one signal receiving unit is fixed to an outside of a casing pipe before the casing plate is cemented in a borehole passing through the monitored zone. At least one housing, defined by projecting elements, (longitudinal members, stops), is provided along an outer surface of the casing pipe, with the where the reception unit being embedded and ...

A brake actuator has a body containing a pair of brake-applying members which may be actuated hydraulically to separate the friction elements of a brake into engagement with a rotatable braking surface. The members are interconnected by a mechanism in the form of a shaft of which respective end portions are provided with reversible threaded portions of opposite hand which engage corresponding thre...

A system for filtering the harmful particulates and liquids from a laser plume formed during surgical procedures. The laser plume may be passed through a suction canister to remove a liquid component from the laser plume. Thereafter, the laser plume is passed through a filter containing granular activated charcoal and a pleated filter to remove substantially all toxic elements and particulate matt...

A method for producing a laminated material comprising a lower layer of highly-expanded plasticized polyvinyl chloride with cross-linking and a surface layer of thermoplastic resin sheet laminated on an upper surface of said lower layer, said method comprising; sufficiently heating and kneading raw materials for the lower layer except a cross-linking agent and a blowing agent mixing with the react...
