Abstract: Metallized sheet-form textiles of synthetic polymers or natural fibres to which a metal layer has been applied by wet-chemical currentless deposition are particularly suitable for screening electromagnetic waves in the range from 10 MHz to 1000 GHz. Since the textile properties are substantially unaffected by the metallization, the sheet-form textiles are particularly suitable for use in the medical and communications fields. A multiple-layer construction with insulating intermediate layers and surface linings may be useful, for example in the screening of relatively low frequencies.

Abstract: A control circuit provides current to the bases of two transistors connected in a Darlington configuration. A load in series with the Darlington collector receives the turn-on current given the improved current gain of this configuration. A diode connected between the Darlington input transistors base and collector begins conduction as soon as the input transistor is saturated. The current applied directly to the base of the Darlington output transistor is enough to saturate the latter at the operating output load current. The invention permits the use of a Darlington switch, and allows the additional advantage of the low saturation voltage of a single transistor.

Abstract: A proportional flow control valve comprises a directional control valve having a valve spool, a servo actuator or servo means for operating said directional control valve, and manual override means for operating the valve spool. The servo means comprises a movable ram or piston for moving the valve spool to thereby operate the directional control valve and the ram has a pair of equally sized piston areas connected thereto. The servo actuator also comprises a pilot valve having a null position and is selectively operable to apply fluid alternately to either of said piston areas to effect ram and valve spool movement in one direction or another from a null position. Means including a proportional electromagnetic device such as a proportional solenoid or force motor are provided for selectively operating the pilot valve. Feedback means are connected between the ram and the pilot valve to maintain the ram and the valve spool in a position wherein they are moved. Orifice means are connected between the pilot valve and the piston areas for relieving fluid pressure on one piston area when fluid pressure is being applied to the other piston area. The orifice means also serve to relieve the fluid pressure on both piston areas whenever the signal to the proportional solenoid is zero and the pilot valve is in null position to thereby prevent ram movement. Biasing means are provided on the valve spool for maintaining the ram and the valve spool in null position whenever the proportional solenoid signal is zero. The biasing means exert a force on the valve spool which is less than the force exerted by fluid being applied to a ram area whenever an electric signal is applied to the proportional solenoid. The override means are manually operable to move the valve spool by means of a mechanical linkage to effect manual operation of the directional control valve.

Abstract: The invention relates to a method and an apparatus for the recovery of spraying substance when spraying elongated rolled stock. Difficulties are met when trying to recover water-dilutable or water-soluble coating agents since after evaporation of the solvent, i.e. the water, the film which is left can no longer be dissolved by water and thus it is no longer possible to recover this fraction of the spraying substance. According to the invention, therefore, it is proposed to carry out the spraying in a water-saturated atmosphere so that the excess spraying substance can easily be recovered. The apparatus is appropriately constructed to correspond to these circumstances.

Abstract: The locking hook 13 has first and second pivotal connection points 21, 25 which are arranged one on either side of the pivot 14, and the unlocking member 17, 17a is connected, or connectable, to a selected one of the first and second pivotal connection points 21, 25. This enables the unlocking member to project either to the one side, or to the opposite side of a towing vehicle on which the fifth wheel coupling is provided. Accordingly, the fifth wheel coupling can be readily adapted for use by vehicles travelling normally on the right, or left hand side of a road. In addition, preferably the pivots 2 and 14 are spaced by the same distance laterally from the longitudinal axis 8 of the vehicle, so that the positions of the coupling claw 3 and locking hook 13 can be interchanged. By virtue of interchanging of the position of the locking hook 13, this provides two further alternative positions for the unlocking member 17, 17a. <IMAGE>

Abstract: A hydraulic brake system for automotive vehicles comprises a master cylinder (4) with at least two working chambers (3,5) and comprising at least two brake circuits. A first brake circuit is in constant hydraulic communication with a first working chamber (3) of the master cylinder (4), while a second brake circuit is connected to the second working chamber (5) of the master cylinder (4). A pressure control valve (1) is inserted into the connection between the working chamber (5) and the second brake circuit, the valve enabling to take influence on the pressure in the second brake circuit in a predeterminable fashion. The pressure control valve (1) is switchable by a slip monitoring electronics (62) so that braking pressure control in the second brake circuit will take place exclusively in the event of failure of the brake slip control apparatus. Thereby, the pressure variation in the wheel brakes, which is performed in a known fashion by suitable change-over of solenoid valves, will not be influenced negatively by the pressure control unit (1) when the brake slip control apparatus is intact.

Abstract: The cooling water can also contain an additive to promote electrode emission and ionisation in its light arc. The additives form a coating on the electrode surface, protecting it against lateral burning. The coating works by forming a sealed layer which prevents oxygen reaching the graphite, substances being present in the additive which are more easily oxidised than graphite and therefore primarily use up an oxygen which may be in contact with the electrode surface. Examples of the additives are silicon cpds. e.g. quartz, sodium silicate or calcium silicate. Oil or other hydrocarbon-based materials can also be added to the cooling water, or combinations of oil and silicon cpds. Concns. of additives must be between 0.1 o/o and 1 o/o and must be disoslved, in finely distributed form or as an emulsion. To stabilise the light arc, titnaium or boron cpds. are added, e.g. TiO2, B2O3 or TiB or TiB2.
