The application describes an offshore support structure for drilling rigs and the like. It includes a column structure which stands on the sea bed. The structure is in at least two sections which are relatively tiltable from an initial position in a plane, or planes, which is, or are, transverse to the column axis by the sections being located one relative to the other by a joint means. The joi...

Polyurethane foam formulations containing halogenated phosphate ester additives are inhibited against scorching through the use of an effective amount of 4,4'-bis( alpha , alpha -dimethylbenyl)diphenylamine.

The invention relates to a process and apparatus for producing a colored band in an extruded thermoplastic sheet. In the process, a probe is inserted in a sheet extrusion die manifold and a colored melt is injected into the polymer melt such that a sheet with an encapsulated colored band is obtained.

A device for a tyre retreading plant is suggested, wherein tyres prepared for the retreading operation and comprising a carcass or casing should be provided with an applied tread band by vulcanizing by the aid of heat and pressure. The tyre retreading plant comprises an autoclave (1). The process heat and the process pressure which are let out at the end of the vulcanizing process are led via a co...

A programmable device for signal processing applications in which short loops of digital data are processed repetitively and in parallel. The device consist of five independently programmable subsystems whose functions are able to operate simultaneously. The apparatus is intended for use in a connection with a digital multiplier device and a digital memory device for such signal processing applica...

Low-color or white, dilutable condensation products of formaldehyde and phenol in molar ratios of 1.9-5.0:1, characterized by carbon-13 nuclear magnetic resonance spectra as having at least about 30 molar percent of the total formaldehyde content of the resin bound to phenol nuclei in benzyl formal groups of the form Ph-(CHuO)u-CHuOH wherein n //cB6 1, and less than about 40 molar perc...

A vinylidene chloride copolymer composition manufactured by the addition of a polymeric blend of a grease copolymer, such as low molecular weight ethylene-vinyl-acetate copolymer, with a conventional plasticizer to improve processing of the composition during mixing and extrusion of the composition as a thin film.

Electronic circuitry monitors the electrical energy consumption of a system and displays the current cost of the energy usage. The projected monthly billing cost is calculated at the current rate of consumption, and an alarm signal and control output are generated if the projected cost is higher than a budget amount. Energy consumption is sensed optically at the electric meter (3) and a proportion...

A beam-splitting prism provided with a roof-edge prism is described. The roof-edge prism is made of a cured transparent synthetic material and can be arranged on a surface of the beam-splitting prism in a simple and cheap manner.

A drive pinion shaft (38) is rotatably supported in front and rear pinion bearings (40,42) and has a shaft portion (38a) on which the rear pinion bearing (42) directly rolls.

A b s t r a c t A system for registrating an article passing a predetermined area, and comprising a transmitter and a receiver with a common aerial alternately transmitting and receiving electromagnetic signals. A marker is attached to each article and receives said signals and transmits in turn other signals at passage of the area. The common transmitting and receiving aerial is formed as a multi...

An article surveillance system employs a label or tag containing a non-linear impedance element, such as a semi-conductor diode, connected to a metal antenna loop configured to pick up two distinct radio frequency transmissions displaced on either side of a selected center frequency. The non-linear impedance element connects opposing sides of a closed loop section at one end of the antenna to form...

Bonding to calcified tissues, including human teeth, tooth dentine and bone, is achieved through the medium of crystal growth adhered to the tissue. The crystals preferably comprise gypsum crystals which are formed by contacting the tissue surface with a mildly acidic solution containing sulphate ions.

A motion detection system which utilizes a lens (21) or other imaging device (21A or 21B) to be responsive to motion in a particular field of view (20) in a room, for example, and pass illumination to a photocell (13). The photocell (13) or a screen (24) in front thereof establishes image distortion so that there is a nonuniform electrical output from the photocell (13) upon motion of objects in t...
