The piezometer intended to be introduced into a drilling hole (3) comprises on one hand rigid measuring rings (b1, b2 ...) intended to be arranged at predetermined distances along the axial direction of the hole, the outer diameter of said measurement ring being smaller than the diameter of the drilling hole, and inflatable sealing means (I) connected to the measurement rings and adapted to be app...

In an apparatus for the grinding or polishing of workpieces, particularly metallographic samples, the grinding or polishing pressure is transmitted to the workpiece (2) through a deformable transmission link (8, 9, 11) which is strained by means of an activating member (14), which is then immobilized. The apparatus comprises means (10) for sensing the elastic deformation of the transmission link a...

PURPOSE:To obtain a normal NTSC multiplexing signal by multiplexing a VBS signal (signal with color burst at black level) and overlapping the VBS signal with a superimpose signal when the superimpose signal without a color burst is frame-multiplexed. CONSTITUTION:NTSC signals are multiplexed by n-number of groups as shown in tables A and B, and moreover a VBS signal is multiplexed for superimposin...

A method of treating teeth with a photopolymerizable composition comprising at least one olefinically unsaturated monomer and an acylphosphine oxide catalyst.

The substitution chlorination reactions of organic compounds are carried out by means of molecular chlorine, using, as a radical initiator, decachlorobutane or an octachlorobutane such as octachlorobut-1-ene or a mixture containing these two products. Good degrees of conversion and good yields are obtained at moderate temperatures. The process is, for example, applicable to the substitution chlori...

A coated rubber cord comprising a core member coated with a woven cover material in the texture of which a single or a plurality of rubber strings are mixedly woven.

PURPOSE:To replace a subscriber FAX terminal with an advanced terminal independently of a system by renewing a FAX subscription terminal capacity class automatically at each communication and making it to newest class information at all times. CONSTITUTION:When delivery is completed, or when a relevant FAX terminal 3 is changed to another type and not delivered, already received information of rel...

PURPOSE:To attain both understanding and operations of commands without using any preliminary knowledge by displaying the full spelling of a command on a display and at the same time attaining discrimination of a cable address part to be supplied through a keyboard under a full spelling mode. CONSTITUTION:An input command 5 is displayed in its full spelling on a color CRT display 4 so that an oper...

PURPOSE:To eliminate the unnatural feeling of writing and to avoid a tailing phenomenon of a magnetic locus by providing a detection plate on a pen holder which can have reciprocating motions and the other detection plate opposite to said first detection plate within a case via a conductive rubber. CONSTITUTION:No pressure is applied to the conductive rubber 7 when no writing pressure is applied t...

PURPOSE:To reduce generation of noise by forming a return flow path within a casing with the provision of a disc therein and integrally providing guide blades on the disc at the position of the return flow path and axial-flow guide blades on the inlet side of the return flow path.

Rigid, water-resistant phosphate ceramic materials are prepared from components comprising metal oxide selected from Al2O3, MgO, CaO, ZnO and hydrates thereof, calcium silicate, and a phosphoric acid solution. By prereacting a portion of the metal oxide with the phosphoric acid and/or by adjusting the temperature of the acid solution when it is combined with the other ingredients, the character of...

A multi-component grouting system having at least one component wherein the active ingredient is contained in the dispersed phase of a water-in-oil emulsion, the oil providing an effective barrier against mixing of the components thereby enabling the components to be stored indefinitely in direct contact. The components may advantageously be encapsulated in a single compartment frangible casing fo...

An anodic aluminum oxide film (12) has a system of larger pores (14) extending in from one face (16) and interconnecting with a system of smaller pores (24) extending in from the other face (26). The film is made by anodizing an aluminum metal substrate, then reducing the applied voltage at a rate to permit partial or complete recovery of the oxide film, either continuously or incrementally in sma...

Apparatus for automatically laminating photoresist dry film (52) onto each of a plurality of panels (63) stacked upright in a panel feed unit (16) with a 10 DEG slant counterclockwise from the vertical, the film being easily contaminated, limp and tacky, although peelable, thereby enabling the use of a polyethylene protective coating, includes a film feed bar (28) for pulling the film from a roll...

In an integrated system, plastic articles are produced in a pressure-molding machine and transferred therefrom to pallets at a receiving station. These pallets are entrained by a first branch of a conveyor which carries them through a temperature-conditioning station to an aftertreatment station in which a finishing operation such as blow-molding is performed upon the articles by a mold with which...
