Abstract: A driving device for a vortex mixing apparatus comprises holders for holding a mixing unit of a type having at each opposite end a pumping diaphragm for imposing a pulsatile flow on a liquid passing through a primary channel in the unit. Two pistons are each arranged to cooperate with a respective one of the diaphragms and to reciprocate between a retracted position clear of the unit and an extended position in which it extends into a housing of the unit and compresses the respective diaphragm. Driving mechanisms are normally arranged to reciprocate the pistons in phase at the same frequency such that when one piston is moving from its retracted position to its extended position the other is moving from its extended position to its retracted position and vice versa. Control mechanisms are arranged, upon stopping of the driving mechanisms, to cause both pistons to adopt retracted positions so that the unit may be inserted into, and removed from the holders without interference from the pistons.

Abstract: The present invention is directed to a method for recovering 2-chloropropionic acid so that this compound can be separated in a high-purity form. According to the method, crude 2-chloropropionic acid is heat-treated in the presence of a metal compound at a temperature in the range of 130-180 DEG C where dichloro derivatives are contained as impurities or at a temperature not exceeding 160 DEG C where no dichloro derivatives are contained. The metal compound is then removed at 160 DEG C or lower. Final purification is thereafter conducted to obtain 2-chloropropionic acid as a high-purity product.

Abstract: The present invention relates to the manufacture of abrasion-proof plates. The abrasion-proof surface of the plate is composed of external face 5 of a layer of composite material based on spherical grains of melted tungsten carbide bonded in a soldering alloy. Grinding surface 5 has a smooth and even mould finish. The abrasion-proof layer contains a compact, regular and essentially uniform random distribution of tungsten carbide grains. Surface 5 is made by moulding: the tungsten carbide grains are inserted between the mould walls and core 2 of the part, and the soldering alloy is made to infiltrate between the powder grains, core 2 and the mould by increasing the temperature. The invention allows a significant increase in the abrasion resistance of grinding plates.

Abstract: In order to produce the electric insulation of the winding of an electric machine, grooves (6) having a cross-section that tapers at least in an area (12) near to the groove opening (11) are arranged in the rotor or motor. Before the winding is laid in the grooves (6), the latter are lined with a laminate (5) that contains an elastically compressed mass of high-elastic, electrically insulating fibres and a solidified, curable synthetic resin that can still be thermally softened, however, and that holds the mass of fibres in its compressed state. Once the winding is laid and the grooves are closed (6), the rotor or stator is subjected to a vaccum pressure impregnation, then cured. During the impregnation process, the hot saturating resin penetrates into the pores of the elastically expandable laminate, elastically expanding the mass of fibres and filling the empty spaces in the grooves, so that the elastically expanded mass of fibres, that is supported at the surface of the groove, exerts on the upper subconductor bundle (8) of the winding a force in the direction of the bottom (10) of the grooves.

Abstract: The application relates to a method and an arrangement for detecting impurities on water surfaces by means of a light absorption measurement. Regular or continuous tests for impurities have to be carried out, in particular, on rivers in the vicinity of industrial plants or power stations which discharge effluent into the rivers. The detection of oil, in particular, plays an important role in this connection. The method and the arrangement evaluate the water vapour formation on a water surface. Impurities on the water surface alter the formation of vapour at said surface. For example, an oil layer acts as a moisture barrier, i.e. water vapour is not formed, or only formed in small amounts, at points on the water surface on which an oil layer is floating. The formation of water vapour at the surface results in absorption losses in a light beam, in particular an infra-red light beam, whose radiation axis is roughly parallel to the water surface. An oil layer floating on the water surface can be detected by measuring the absorption losses. <IMAGE>

Abstract: An aqueous external release agent for the production of tyres and of other rubber articles is described, which release agent contains 5 to 35% by weight of diatomaceous earth, 0.5 to 6% by weight of pyrogenic hydrophobic silicic acid, 0.1 to 2% by weight of non-ionic surfactant, 0.2 to 3% by weight of a binder, 0.1 to 3% by weight of colorant, 0 to 5% by weight of ethyl alcohol and the remainder water. Preferred binders are styrene/maleic acid or styrene/maleic anhydride copolymers and especially the ammonium salts thereof. These external release agents are used in processes for moulding and vulcanising tyres and other rubber articles, the release agent being sprayed onto the preform with the aid of air-atomisation pistols before moulding and vulcanisation are carried out. A very good release effect is thus obtained without the vulcanisation being impaired. Because only very small quantities of external release agent are required, cleaning of the compression mould and thus an interruption of the production process are necessary much more rarely than when using conventional external release agents.

Abstract: A multi-rate commodity metering system comprises an electronic key containing an EEPROM, and a meter for metering the commodity and having a receptacle for receiving the key. The meter also contains a real-time clock. The key can operate as a programming device and a meter-reading device. When the key is initially inserted into the meter, it starts a billing period, eg a quarter, and if necessary programs the meter with the times for switching between rates and the prices per unit of the commodity for each rate. Towards the end of the billing period, the meter reading is entered into the key with the time and date to which it relates and a visible and/or audible warning is produced to remind the customer to remove the key and take it to the commodity supplier's premises so that the supplier can read out the meter reading from the key. If the customer fails to do this within a certain time, the supply of the commodity is cut off, although an emergency supply can be obtained for a further predetermined time if necessary.
