PURPOSE:To execute follow-up running with high accuracy and at a low cost, by forming a running reference line in a state that it can be detected by a lateral displacement detecting device, feeding a rope by a feeding and collecting device, and dragging a car body along the reference line. CONSTITUTION:A service car is provided with devices 8a, 8b for feeding and collecting ropes 6, 7, devices 9a,...

PURPOSE:To improve a maintenance property and reliability of a bit slice control device, by checking a sequence code in case when an error occurs, so that a position where a fault occurs can be recognized. CONSTITUTION:A shift register 3 is connected to an output side of a control part 1 through an AND circuit 2. Plural sequence codes corresponding to a bit serial data group to be converted to a f...

A heat wave shielding lamination consisting of at least two In2O3 shield layers containing different amounts of Sn is provided on the surface of a glass substrate to provide shielding against heat waves without causing heat wave pollution in the surrounding environment. The amount of tin contained in the respective layers increases with increasing proximity to the substrate. The heat wave shieldin...

The glider (22) consists of a plastic shell (24) and a pipe clip (26), for example made of chromium steel, which together are clamped by means of a screw (28) to the tube or the runner (18) of an item of furniture. Constructed in the shell (24) are recesses (30, 32) which are separated by a central web (34) and into which the ends (38 and 40) of the pipe clip project. Guided through the shell (24)...

The shell is removed from a crustacean by creating a pressure difference across the shell. Initially the crustacean is heated until body liquid adjacent the shell is just below boiling point. The pressure on the crustacean is then suddenly lowered to induce the liquid to boil and thereby create the pressure difference across the shell. After pressure treatment, the crustaceans are projected into a...

{PG,1 A closed cell phenolic-resin foam material comprising phenolic-resin foam forming reactants, a blowing agent, and a surfactant which is the capped reaction product of an alkoxylated amine and a copolymerizable mixture of dialkyl maleate with N-vinyl-2-pyrrolidone or N-vinyl caprolactam.

A method is suggested for the reduction of finely-divided iron oxide in a fluidized bed, with the air of reducing gases formed by partial combustion in the bed of finely-divided carbonaceous material by gas containing molecular oxygen, which is supplied through nozzles (4). The exterior surface of the nozzles is cooled to a temperature lower than 200 DEG C below the melting point of the reduced m...

A process for the production of a moldable fibre-containing cementitious composition in which at least one mat of a water-insoluble fibrous material is contacted with at least one surface of a shaped article of a moldable cementitious composition, the cementitious composition comprising a homogeneous mixture of at least one hydraulic cement, water in a proportion of not more than 25% by weight of ...

The adhesion of the coatings to crosslinked organopolysiloxanes, is improved by applying to the surface, before coating or adding to the coating composition a silane containing per molecule (a) at least one amino group that is bonded through one or more carbon atoms via an SiC-linkage and optionally one or more other atoms, to a silicon atom, and (b) at least one silicon-bonded monovalent hydrocar...

An electronic cash register includes a PLU (Price-look-up) function, wherein merchandise information such as a unit cost, taxation information and classification information is preset for each commodity by an operator. For presetting the PLU code information, a "PLU" key is actuated for automatically developing a PLU code signal in a progressive order. A synthetic speech sound generation system is...

A boring-injection device comprises a fluid supplying hollow rod, a fluid discharge portion at the lower end of the rod, and a packer element inflatable from the rod to seal a space between the rod and a borehole wall at a desired depth position. The rod is surrounded by a sheath so that the packer element and fluid discharge portion can be protruded out of and retracted within the sheath in a bod...

An aqueous phenol formaldehyde resole, suitable for use in the manufacture of phenolic foam insulation, has a molar ratio of formaldehyde to phenol in the range of from about 1.7:1 to about 2.3:1, and a weight average molecular weight greater than 800. Preferably, the resole also has a number average molecular weight greater than 350 and a dispersivity greater than about 1.7. Phenol formaldehyde r...

A closed cell phenolic foam having a cell structure in which the cell walls are substantially free of both ruptures and perforations is made by foaming and curing a foamable phenolic resole composition containing an aqueous phenol formaldehyde resole, a surfactant, a blowing agent and optionally other additives, with an acid foaming and curing agent which is an anhydrous aryl sulfonic acid which h...
