Title: Process for refining silicon produced in an arc furnace
Inventor: FENZL HANS J DIPL ING
IPC: C01B33/037
Filed: 1984-01-30
Abstract: The invention relates to a process for refining silicon produced in an arc furnace, removing non-reduced quartz or unreacted carbon. To this end, the silicon is fused in a highly compacted graphite crucible (4) or a quartz crucible, as a result of which the non-reduced quartz and the unreacted carbon collect on the crucible wall. If required, it is also possible to charge the graphite crucible with slag- or glass-forming fluxes. Subsequently, the silicon thus refined is processed further by means of zone drawing or, according to Czochralski, into single crystals. <IMAGE>

Title: Spinning apparatus for chemical fibres with a blow-on box and spinning shaft
Inventor: RUNKEL WALTER DR ING
IPC: D01D5/092
Filed: 1984-06-30
Abstract: In a spinning apparatus for chemical fibres, the cooling of the fibres issuing from the spinnerets takes place by means of a turbulence-free air stream. For this purpose, the threads are guided through a perforated tube. The perforated tube is surrounded on all sides by an air box. In the region in which compressed air is fed to the air box, the tube is not perforated. In the remaining region, the air permeability is distributed in such a way that the air permeability is greatest in the vicinity of the spinneret and decreases towards the bottom of the air distributor box. In order to distribute the air permeability, there can be slipped over an inner perforated tube with a uniform perforation an outer tube which has the desired distribution of air permeability by means of a corresponding perforation.

Title: Control arrangement for a hydraulic system
Inventor: NONNENMACHER GERHARD DIPL ING
IPC: A01B63/111
Filed: 1984-08-29
Abstract: The control arrangement for a hydraulic system has a pressure control valve (19) for an adjustable pump (10) which has a working cylinder (13) for actuating an implement, in particular a plough. The working depth of the implement is to be kept constant, which requires a desired/actual-value comparison. The actual value is signalled to an electronic control device (33), for example via a scanning device. The control device (33) controls an electromagnetically operable proportional pressure valve (26) which in turn influences the pressure controller (19). In interaction with these devices, the working pressure in the cylinder is kept constant by appropriate setting of the pump (10). The adjustable pump is a pressure-controlled pump with reversible delivery direction while the pressure side remains the same. In this way, accurate plough-depth control is obtained in an especially efficient operation, since, for example during a lowering movement of the working cylinder, the lowering energy is fed back as torque to the motor driving the pump. <IMAGE>
Patent DE-3434014-A1 (DE)
Inventor: HAEUSSLER HUBERT
IPC: B66B1/04
Filed: 1984-09-15
Abstract: A hydraulic control system for an elevator or other similar reciprocating user is disclosed, which comprises an adjustable throttle valve and a control or bypass valve disposed in the fluid supply line between the pump and elevator. A pressure difference balance is provided for controlling the operation of the control valve, and the pressure difference balance has one end operatively connected to the pressure provided by the pump, and the other end operatively connected to the pressure in the user or load line. The control valve is thus adapted to maintain a desired pressure difference across the throttle valve which is independent of the load on the user. In addition, the zero setting of the pressure difference balance is adjustable, so as to permit the system to be equally operable in both the upward and downward movements of the elevator.

Patent DE-3521801-A1 (DE)
Title: Hydraulic tool-clamping system
Inventor: HAMANN HORST
IPC: B23B31/30
Filed: 1985-06-19
Abstract: The hydraulic tool-clamping system is suitable for the true-running, axially defined fastening of tools in high-speed spindles in an easy, quick and even automatic tool change. In addition, special tool chuckers are superfluous and the spindle need no longer be bored through for such a tool chucker. A tapered hydraulic external expansion clamping sleeve, which compensates in a flexible manner for the variable spindle opening and fastening at high rotational speeds, produces the frictional connection with the tapered spindle opening for the torque transmission. The clamping for this closed hydraulic system is initiated by a separate screwdriver located outside the spindle. This external expansion clamping sleeve is combined with a hydraulic internal expansion clamping sleeve for accommodating small, preferably cylindrical or even tapered tool shanks which can be produced cost-effectively, or with a hydraulic external expansion clamping sleeve for accommodating larger bored tool shanks, or with fastening devices for indexable inserts or with a steep-taper socket.   The hydraulic tool-clamping system is especially suitable for high-speed milling.
