Abstract: Liquid friction coupling, in particular for driving the radiator fan of an internal combustion engine, consisting of a driven coupling part and a coupling part driven by the latter as a function of the fullness of a working chamber and provided with a braking device. The braking device is designed as a dynamic brake which is actuable by an electromagnet (25) and engages on the driven coupling part (1). By virtue of this configuration, the coupling can be braked or halted at any time and for a brief period without allowance for inertia effects. A bimetallic control device for controlling the fullness of the working chamber is not required. <IMAGE>

Abstract: An optical fiber aligning member includes at least two grooved substrates (1), each of which has a first main surface (2) in which optical fiber aligning grooves and at least two first positioning grooves are formed and a second main surface opposite the first main surface in which at least two second positioning grooves (3) are formed. The grooved substrates are laminated on top of each other in a manner so that each grooved substrate is alternately turned over. First positioning pins (5) are positioned in the first positioning grooves and second positioning pins (6) are positioned in the second positioning grooves for aligning the alternating grooved substrates. In a method for making the optical fiber aligning member, the fiber aligning grooves and the positioning grooves are formed in the surfaces of a flat plate. The grooved substrates are formed by dividing the flat plate at an angle perpendicular to the grooves. The grooved substrates are stacked alternately so that grooved substrates that were adjacent each other in the flat plate are stacked adjacent each other in the optical fiber aligning member with their positioning grooves opposing each other.

Abstract: 1. Process for the optimised operation of two or more compressors in parallel or series operation. 
<??>2.1 Known processors of the said type assume identical compressors and attempt to optimise their operation by averaging the output and/or load of the individual compressors. This averaging affords no guarantee of optimum operation. It is not possible to take account of differing compressors. The new process is intended to ensure economically optimised operation of two or more compressors connected in parallel or in series, including different compressors. 
<??>2.2 The new process is essentially characterised in that the working points of each two compressors are incrementally shifted in opposite directions without affecting the overall operating parameters. In so doing the effect of this shift on the sum of input parameters is observed. In the event of a change in the direction of optimisation there is a further shift in the same direction; otherwise the shifting direction of the working points is reversed. In this way the compressors are eventually brought into the optimum working point combination. 
<??>2.3 The new process can be used for the parallel and series operation of any compressors in many technical spheres, for example the chemical industry, the iron and steel industry, etc.

Abstract: An improved device for containing and administering orally active therapeutic agents is described. A unit dose of a therapeutic agent in free-flowing form is retained and positioned for oral administration in a tube adapted to deliver the dose with a flow of liquid drawn through the tube by normal sipping action of a patient. The combination of small particle size and high flow rates into the alimentary canal allow dosage administration with minimal sensed contact with the oral cavity. The invention is particularly advantageous for the administration of orally active therapeutic agents to pediatric and geriatric patients.

Abstract: There is disclosed a root crop harvesting machine, especially a potato harvesting machine (10) which can dig-­up two rows (11) of crop and then discharge the crop laterally of the machine to any required extent via an elevator (14) which is adjusted to a lateral discharge mode, as shown in Figure 1, to permit the dug-up crop to be deposited in rows (18) for drying purposes. Once drying has been completed, the same machine (10) can then be used to pick-up the dried crop and then, following adjustment of the elevator (14) to an elevational position, the dried crop can be discharged into a collecting vehicle (21). The harvesting machine of the invention therefore has two discharge functions, and can replace two existing pieces of equipment. The invention also enables novel methods of crop harvesting to be carried out.

Abstract: The underground formation and the adjacent zone are for example an oil bearing stratum (Z1) and a subjacent aquifer (Z2) at a pressure greater than that in this layer (Z1). The method essentially consists in drilling at least one deviated drain hole (D) (preferably horizontal or almost horizontal) traversing the oil bearing layer, the adjacent zone and the intermediate layer (L) which is for example a zone made to have low permeability because of the presence of heavy and viscous hydrocarbon products. The drain hole is fitted with a pipe (C) pierced by orifices (01, 02) at the level of the two zones (Z1, Z2) and with stopping units (BP, BO). The delayed opening of the unit (BP) during production, allows the injection of water under pressure into the oil bearing layer and a better draining of the formation.
