Abstract: Invention is a system for automatic control of a rotational drill (1) of which one input is connected to a regulator (2) for control of an axial load distribution on a drill tool, while a second input is connected to a regulator (3) for control of the drill tool's rotational frequency, whereby each regulator is connected via its comparator (4 resp. 5) to a preset sensor in order to preset the quantity to be regulated, while the drill's (1) outputs are connected to a drill speed sensor (7), a sensor (8) for detection of the drill tool's rotational frequency, a sensor (9) for detection of the axial load distribution on the drill tool, and a sensor (10) for detection of drill tool torque as well as a vibration speed sensor (11). The aim of this invention is to increase the accuracy in automatic regulation of the optimal parameters upon change of drilling conditions while simultaneously simplifying the control units. The invention is distinguished notably in that the system is equipped with a unit (13) for calculation of the drill's depth-movement per rotation of the drill tool, this unit's inputs being connected to a drill speed sensor (7) and rotational frequency sensor (8), while the unit's (13) output is connected to a comparator (5) for comparison of the drill tool's instantaneous depth-movement per rotation of the drill tool with a predetermined value, that is to be determined by a calculator (6) of which the inputs are connected to a drill speed sensor (7), sensor (8) for detection of the drill tools rotational frequency, a sensor (9) for detection of the axial load distribution, a sensor (10) for detection of drill tool torque as well as a vibration speed sensor (11) and to the preset sensor (12) for presetting the input parameters and the outputs of which are connected to the comparator (5), the regulator (2) for control of an axial load distribution, the regulator (3) for control of the drill tool's rotational frequency, and the comparator (4) for comparison of the drillability of the material to be drilled into with the predetermined value.<IMAGE>

Abstract: The invention relates to a device for dosing or for pumping in a controlled manner a liquid or slurry, a device having a piston freely reciprocating in a cylinder; members connected to the cylinder on the opposite sides of the path of the piston movement for feeding the liquid or slurry under pressure into the cylinder in order to move the piston or for discharging liquid or slurry from the cylinder by means of the pressure of the liquid or slurry directed into the cylinder to the opposite side of the piston, when the piston returns; a valve member in the feed and discharge members of the liquid or slurry for their alternate opening and closing; switches fitted at the ends of the cylinder for sensing the position of the piston; and a control unit for controlling the stroke frequency of the piston, and thereby the volume flow of the liquid or slurry, and for transmitting the signal given by the switch to the valve member in order to open and close it at different positions of the piston. According to the invention, the control unit has been fitted to adjust the time interval between the starts of the piston movement. Thus the stroke frequency of the piston and the volume flow of the liquid or slurry remain constant in spite of variations in the feed pressure and viscosity of the liquid or slurry.

Abstract: The solenoid valve actuates a pilot valve body which cooperates with a stationary seat surface. The pilot valve body actuates a main valve body of an on-off valve having a piston with a calibrated leakage. The cylindrical chamber on one side of the piston communicates with the inflow side of the on-off valve when the solenoid valve is opened via the pilot valve body, and the cylinder chamber on the other side of the piston communicates directly with a discharge. That side of the piston which is near the main valve body is isolated from the flow path of the on-off valve. The possibility of leakage is reduced considerably for a very reduced constructional outlay, electricity consumption is low and the loss of valve-time cross-section associated with an opening instruction is reduced.

Abstract: A hydraulic motor vehicle servo brake comprises a pedal-actuated master cylinder (11) with at least one master piston (24). In addition, a brake valve (17) is provided for boosting of the brake force, which brake valve upon actuation by the brake pedal (16) feeds pressure medium supplied by a hydraulic pump (18) connected to a supply reservoir (27) in a controlled way to the master piston (24). Furthermore, a pressure accumulator (45) is provided which is maintained in loaded condition by the pump (18) and is of such capacity as to ensure that it supplies sufficient pressure during the running-up phase of the pump (18) after the motor (147) is started. A control valve (46) connected to the pressure side of the pump (18) comprises a closing member 47 which normally closes a passage to a return conduit (48) leading to the supply reservoir and is pressurized by the pressure of the pump (18) against the force of a closing member spring (49). Thus the pressure of the pump can be reduced when the controlled pressure is low and the pump is in operation. Furthermore, a control valve (50) pressurized by the controlled pressure is provided. The closing member spring (49) influences the closing member (47) by way of a relief piston (53) disposed in a cylinder (52). The relief piston (53) is pressurized against the action of the closing member spring (49) by the controlled pressure. Between the relief piston (53) and the closing member (47) a week auxiliary spring (54) is disposed whose force is just sufficient to keep the closing member (47) in closing position when the relief piston (53) is in lifted position.

Abstract: The invention relates to a silkscreen printer having a cylindrically curved printing table intended for applying print to print material. The printer further comprises a stencil which is stretched in a stencil frame arranged for reciprocating movement in response to reciprocating of the printing table (2), and also a squeegee device which is intended to press the stencil against the printing table and therewith transfer print onto print material located between the printing table and the stencil. The printer further comprises a gripper (8) which co-acts with the printing table (2) and which is intended to grip firmly the forward end portion (3a) of the print material (3), as seen in the direction of movement, during at least a part of the printing sequence. The gripper (8) is mounted in the printing table (2) for pivotal movement in the direction of the longitudinal curved extension of the printing table. When occupying a registered position the gripper (8) is pressed against a stop means (13) by means of a spring device (16) such as to register the gripper in relation to the printer chassis (10), this registration being effected without taking into account the stop position of the stencil frame and printing table (2). It is suggested that Figure 3 is published together with the abstract.

Abstract: Molten metal is drawn upwards through one or more inlets into a mould in the process. A vacuum is applied so that the molten metal fills the mould and rises into at least one riser pipe. The metal in the inlets to the mould is caused to harden as soon as a required level in the riser has been reached, so that the molten metal is enclosed in the mould. The mould is then pressurised. The hardening of the metal in the inlet is produced by a redn. in the velocity, or a cessation, of the entry to the mould and is in the form of a slot whose width is less than that of the thinnest section of the shape being cast. The mould may be enclosed in a gas-tight cover for the application of the vacuum and pressurisation. USE/ADVANTAGE - Used in the casting of metal shapes for various uses. The molten metal is enclosed in the mould before it can harden, so that the application of an external pressure can be used to ensure that all of the mould is completely filled. No valves are used, thus making the process simple and economical, since it is difficult for valves to survive the temps. involved in the casting of molten metals.
