The method utilizes changes in pressure sensed in the drill head or the conveying tube as a means for assessing forces acting on tools in the drill head. The measured pressure information is transmitted to control equipment which adjusts the driving force applied by a power unit to the apparatus to effect the drilling operation. The method thereby provides an effective means of preventing damage to the tools.

Abstract: A dual circuit hydraulic brake system with front/rear split brake circuit, antilock brake system (ABS) and wheel slip control (ASR) for motor vehicles has a four-duct hydraulic unit (20) with control valves (31-34) and with a return pump (27) with two separate pump elements (28, 29) for each brake circuit. A device for supplying brake pressure to the rear axle brake circuit in the case of wheel slip control has a reversing valve (43), which in the event of wheel slip control separates the rear axle brake circuit from the master brake cylinder (15) and a pump feed device (44) which, when activated, feeds brake fluid into the pump element (28) of the rear axle brake circuit. In order to achieve an optimum division of brake force between front and rear axle, when the brake pedal is operated an electrical control device (30) switches the reversing valve (43) into its closed position, switches the return pump (27) on and activates the pump feed device (44) at least until such time as the brake pressure generated in the rear axle brake circuit by the pump element (28) corresponds to a set value predetermined as a function of the brake pressure in the front axle brake circuit. <IMAGE>

IPC: A61P25/04
Filed: 1991-04-18
Abstract: The present invention relates to a medicament with an analgesic, antipyretic and/or antiinflammatory effect based on a salicylic acid derivative. The state of the art is always searching for alternatives to active ingredients such as acetylsalicylic acid (ASA) and ethenzamide in order to eliminate intolerance or to be able to offer simpler and better ingredients, which act as rapidly as possible, for a wide variety of possible administrations. Surprisingly, the invention has now succeeded in demonstrating that ethenzamide is very rapidly and completely metabolised in the human body to 2-Ethoxybenzoic acid. Ethenzamide is only a prodrug. It was possible to rule out metabolism to salicylamide. It was likewise possible to demonstrate the analgesic effect of 2-ethoxybenzoic acid. It correlates with the serum levels and persists for more than 8 hours. 2-Ethoxybenzoic acid is very rapidly absorbed. The serum maxima are reached after only 30 minutes; 2-ethoxybenzoic acid is still detectable in the serum even after 24 hours. These properties make 2-ethoxybenzoic acid an ideal analgesic which has a rapid onset of action and which has no effect on blood coagulation. Since the bioavailability is higher, it is also possible to reduce the single doses. By virtue of the physicochemical properties of 2-ethoxybenzoic acid, use in the form of a solution is possible so that, besides solid drug forms for oral and rectal use, it is also possible to prepare and use liquid formulations such as solutions for administration as drops or by injection. <IMAGE>

Abstract: In CD players, both the focus error signal and the track error signal are superposed by high-frequency oscillations which hinder control and are caused by data recorded on the disc. The track error signal and the focus error signal are generated by forming the difference between the output signals of a plurality of photodiodes. 
<??>Because the high-frequency components are shorted by means of a capacitance (K) before forming the difference between the output signals of the photodiodes (A, B, C, D), high-frequency components hindering control are no longer contained either in the focus error signal or in the track error signal.

Abstract: The proposed tool holder has the advantage that accurate round holes can be made with it, using a hammer drill, even if the tool-holding fixture is deflected. For this purpose, the transmission of the precursive-mechanism action is suppressed and a tool holder (28) is fixed to the collar (29) of the hammer drill and centred. A drill chuck (28), arranged in the extension of the tool-holding fixture (4) of the hammer drill and connected to the rotary drive of the hammer, ensures exact concentric running of the inserted drilling tool. <IMAGE>

Abstract: The procedure serves to hone two or more aligned bore holes which are provided inside a workpiece and are connected to one another. If such bore holes are worked simultaneously with a single honing tool, geometrical inaccuracies occur if correspondingly long honing sticks are used and dimensional inaccuracies as a result of different wear occur if two sets of honing sticks arranged one above the other are used. These disadvantages are avoided with the procedure according to the invention, in which the bore holes (2 and 3) are honed in successive working steps, the honing tool (5) working with short honing sticks (6) in one bore (2 or 3) and being guided with guide sections (9; 10) in another bore (3 or 2). <IMAGE>
