The control circuit comprises a main servo loop (9, 11, 12) for positional control and an additional servo loop (13, 14, 12'') for force control which comes into action in a certain phase during the processing operation, e.g. of a press cycle, and takes over the control from the main servo loop. <IMAGE>
Patent DE-3426046-A1 (DE)
Title: Electrical continuous-flow heater having a controllable outlet temperature
Inventor: ECKERFELD ALFRED
IPC: F24D10/00
Filed: 1984-07-14
Abstract: An electrical continuous-flow heater produces a basic power using three heating resistors 32, 34, 36 and a controllable power using three heating resistors 38, 40 and 42. The controllable power is controlled by a controller 44, via triacs 46, 48, 50. When the water flow in the continuous-flow path 10 is low, only two phases are connected, via switching contacts 84 and 86. A low basic power is then produced by connecting the heating resistors 32 and 34 in series. A correspondingly low, controllable power is supplied via the heating resistor 42. If the switching contact 88 also closes, then all the phases are connected. The heating resistors 32, 34 and 36 are then connected in star and the heating resistors 38, 40, 42 in delta. The heating channels 16 to 26 are parallel, straight channels in a channel block 52. The heating resistor ends 54 to 64 and 66 to 76 are passed out of the heating channels 16 to 26 at both ends. <IMAGE>

Title: Handbrake valve for brake systems, especially of motor vehicles
Inventor: VOLLMER OTTO
IPC: B60T15/02
Filed: 1984-07-31
Abstract: In a handbrake valve, especially for motor vehicles, the rocker lever (1) is provided with a shift rod (7), connected to a control element (5) for the valve mechanism and fixed in an axial direction but capable of swivelling in a rotational direction, which outside the shifting gate (3) of the handbrake valve is enclosed by a shift sleeve (11) connected to the gear shift knob (9); the shift sleeve (11) in turn carries a ratchet element (13), which in the area of the gate opening (37) of the shifting gate (3) can be shifted into a detent position inside the gate opening under the action of a detent spring (17), without force components directed axially outward and acting on the gear shift knob (9) exercising any locking or retarding influence on the detent movement during operation of the rocker lever. Starting from the parking brake position in the gate opening (37) of the shifting gate (3), the detent element (13), by means of the shift sleeve (11), can be pressed by a further degree in the direction of the control element (5) of the handbrake valve if the rocker lever is to be swivelled out of the parking brake position into the control position. In addition, the detent element (13), by means of the shift sleeve, can be raised radially outwards in the direction away from the control element (5) if the rocker lever is to be unlocked from the parking brake position and swivelled back into the release or drive position. <IMAGE>

Patent DE-3441734-A1 (DE)
Title: Hip endoprosthesis with force transmission adapted to the natural bone conditions
Inventor: SCHMIDT JOACHIM DR MED
IPC: A61F2/36
Filed: 1984-11-15
Abstract: After implantation of conventional hip endoprostheses into the proximal end of the femoral shaft, loading results in a theoretically possible tilting movement of the prosthesis which leads to an unnatural load on the bone. The construction principle of a hip endoprosthesis comprising two half-shafts, which are each hinged in the prosthetic neck to a support carrying the prosthetic head, avoids action of the force of the theoretically possible tilting movement. The external half-shaft is placed under tension while the inner one is placed under pressure if there is a possibility of vertical sliding relative to one another (see Figure). This load is transmitted separately on to the bone in each case. This tensile and compressive load corresponds to the load of an intact femoral bone. This natural force transmission leads to a longer implantation period of the prosthesis. <IMAGE>

Patent DE-3500649-A1 (DE)
Title: Process for preparing waterglass solutions
Inventor: HUSSMANN PETER DR
IPC: C01B33/32
Filed: 1985-01-10
Abstract: Process for preparing waterglass solutions of commercial composition and density by reacting quartz sand with aqueous sodium or potassium hydroxide at elevated pressure and temperature in an autoclave, which process involves reacting quartz sand and aqueous alkali metal hydroxide in such a proportion that a reaction product is formed which under the reaction conditions is liquid but under normal conditions is solid, and in which process the hot, liquid reaction product formed in the autoclave is allowed to flow into at least one vigorously stirred water-containing receiver, which is disposed directly on the autoclave and which contains the amount of water required to dilute the reaction product to give a waterglass solution which is liquid under normal conditions and which has the required density. The process can be carried out particularly advantageously if it is performed in a drum-shaped autoclave having two associated receivers which are alternately used to dilute the reaction product and to prepare a new batch.

Patent DE-3507459-A1 (DE)
Title: Glow ignition device for an internal combustion engine
Inventor: BEZOLD URS
IPC: F02B23/06
Filed: 1985-03-02
Abstract: In internal combustion engines with mixture formation in the cylinder the time available for mixture formation and ignition is very short. The consumption, emission and noise levels are essentially a function of the mixture formation and ignition delay. Immediate heating of the fuel after entering the combustion chamber speeds up the mixture formation and reduces the ignition delay. Internal combustion engines on this principle can be operated with different fuels with favourable consumption, emission and noise levels. <IMAGE>

IPC: A63H23/16
Filed: 1985-04-18
Abstract: A device for the locomotion of model vehicles along a predetermined path comprises a closed casing which is designed as a box and in which a motor is situated which drives a pulley which is held so as to be able to rotate about an upright tube which passes through the centre of the box. The pulley supports one or more slide rods for guiding the model vehicle. A cover supported by the upright tube covers the entire drive. The box can be arranged for operation of model water-going vehicles inside a container. It is possible for the model vehicles to have their own energy supply owing to a bipolar design of the pulley and the drag rods. A plurality of boxes are provided for individual path guidance, the pulleys taking the form of V-belt pulleys around which circulates a V-belt which supports the drag rods for the model vehicles.

Title: Method for measuring the electrolytic conductivity of fluids
Inventor: SCHEFFOLD CHRISTOPH
IPC: G01R27/22
Filed: 1985-05-17
Abstract: A method for measuring the electrolytic conductivity of fluids in a measuring cell, containing the fluid to be investigated, with two electrodes immersed in the fluid and arranged at a predetermined distance from one another. A direct-current pulse of predetermined direction, having a predetermined length in time and a predetermined constant current intensity is sent through the measuring cell. During the duration of the direct-current pulse, the voltage prevailing across the cell is continuously measured at predetermined time intervals. From the measured voltage values, the first and the second derivation of the function of the measured voltage variation is in each case calculated in dependence on time. Then the voltage value is determined at which the first and/or the second derivation has the value 0 or has changed the sign compared with the previous value. This selected voltage value is allocated to the measured current value and used for determining the conductance.
