Abstract: Disclosed is a process for forming an uninterrupted coating of uniform thickness on the inside of a length of tubing which comprises the steps of forming a loop of tubing with a downwardly inclined portion and an upwardly inclined portion; filling the cavity of the tubing forming the loop with a coating liquid; transporting the tubing along its longitudinal axis in a substantially vertically upward direction to coat the inside of the tubing, above the level of the coating liquid, with an initial layer of coating material; constricting the tubing to lay partially flat along a narrow zone running transverse to the direction of transportation above the level of the coating liquid to retain the greater part of the coating liquid in the constriction zone and form a thin layer of coating liquid of desired thickness on the inside; of the tubing issuing from the constriction zone; filling the cavity of the tubing issuing from the constriction zone with support gas; and exposing the tubing to the action of heat at a sufficiently high temperature to fuse the coating layer to the inside of the tubing and form an uninterrupted film of uniform thickness on the inside of the tubing. Also disclosed is an apparatus for carrying out the process of the present invention.

Abstract: A method for manufacturing a protection sleeve and a protection sleeve as manufactured accorcling to the method for equipment for testing or test sampling liquid metal by introducing the protection sleeve (3; 3 min ; 3 sec ) together with a testing or sampling means (2; 11) provided inside the protection sleeve into the liquid metal (1), whereby the protection sleeve provides a controlled and predeterminable flow of metal at least at or adjacent the walls of the protection sleeve. The protection sleeve comprises a thermoinsulating tube (3; 3 min ; 3 sec ) made of synthetic amorphous mineral fibres, preferably fibres of diabase type and having a sagging point of 1000-1200 DEG C according to the standards of the Swedish Institute for Materials Testing, and bound with an evenly distributed binder comprising or including among other things a binder component of organic type, for instance a thermosetting resin like phenol resin, carbomide resin or melamine resin and or substances incorporated in the fibre material, for instance crystal water containing salts or carbonates which at the temperature of the liquid metal spontaneously and successively emit gases. The mineral fibre tube (3; 3 min ; 3 sec ) can be manufactured from mineral fibres having an original weight per unit of volume of 20-70 kg/m<3>, which have been compressed to a weight per unit of volume of 200-800 or preferably 500-700 kg/m<3>. Preferably the binder is added in an amount of 2-8% by weight. The intensity of the turbulent flow is controlled by varying the amount of binder in the thermoinsulating mineral fibre tune and/or by varying the hardness of the mineral fibre tube.

Abstract: An elevator system stopping control generates the difference between the actual speed value and a set point speed value on the transition from an unregulated travel phase to the regulated arrival or braking phase and prevents that difference from becoming effective so that the travel comfort is not impaired and the stopping accuracy remains assured. For this purpose, a multiplication factor is formed from the actual speed value and an associated nominal speed value by means of a divider during the travel phase before the onset point of braking and stored during the arrival phase in a memory. Stored in a travel curve memory are travel-dependent set point speed values, which values are multiplied by the factor by means of a multiplier and conducted as set point signals to a motor speed regulating circuit during the arrival phase.
