Title: Machine for the compressive forming of metallic workpieces
Inventor: RIBBACK ERICH
IPC: B21J7/14
Filed: 1982-08-19
Abstract: The invention relates to a machine for the compressive forming of metallic workpieces, having at least two die carriers (3), which are guided linearly in the fixed machine frame (1), are provided with forming dies (4) and to each of which is assigned a push-action tappet (5) which is supported in a jointed manner both on the die carrier and on a driving element rotatable backwards and forwards and, by its pivoting movement, produces the strokes of the associated die carrier (3). In order to simplify the structure of a forming machine of this kind and in order to achieve running which is as far as possible without play and frame spring, each push-action tappet (5) is, according to the invention, assigned a separate driving element (6) which is pivotably mounted on the machine frame (1) in a manner which allows it to be pivoted about a fixed pivot (7) intersected at right angles by the longitudinal axis of the associated die carrier (3), the driving elements (6) being connected to one another by at least one reciprocating connecting rod (8), which engages in a pivoted manner on the driving elements (6), at a distance from their pivots (7). <IMAGE>

Title: Manually operated shift device for the transmission of motor vehicles, especially of tractors which can be used in agriculture and/or the construction industry
Inventor: UNSINN MARTIN
IPC: B60K20/08
Filed: 1982-12-22
Abstract: A manually operated shift device for gearboxes of motor vehicles, especially of tractors which can be used in agriculture and/or the construction industry is described, in which a shaft 7 for engaging the gears can be swivelled by the manual shift lever 1 and is longitudinally displaceable for the selection of one of two selector plate slots by a member. In order to be able to design the gate, in which the manual shift lever 1 is guided, as simply as possible, only the swivelling of the gear shift shaft 7 (engagement and disengagement of gears) is assigned to the manual shift lever 1, whilst for longitudinal displacement of the gear shift shaft 7 (engagement of the selector plate slot), the selector member, a lifting magnet 13, is provided. The lifting magnet 13 actuatable by way of a control element arranged on the manual shift lever 1, at the same time acts directly on the gear shift shaft 7. So that the longitudinal movement of the gear shift shaft 7 is not imparted to the manual shift lever 1, a component is arranged in the transmission linkage between manual shift lever 1 and gear shift shaft 7 so that it can absorb the movement of the gear shift shaft 7 but without transmitting it further.

Title: Process of producing structural members from dense silicate concrete
Inventor: KUEHNE GERD DIPL ING
IPC: C04B40/00
Filed: 1983-03-14
Abstract: The invention relates to a process of producing structural members from dense silicate concrete with the use of the residual fresh concrete. At present, effectively including the residual fresh concrete in a continuous technological process constitutes an unsolved problem. It is known to feed the residual fresh concrete again to the shaping process. However, structural members of poorer quality then frequently result since structural defects occur as a result of advanced hydration in the residual fresh concrete. The purpose of the invention is to eliminate this defect and to obtain a reduction in the cost of production and a better utilisation of the raw materials. The object of the invention is to permit the reuse of the residual fresh concrete in a closed system, the uniform moisture content and the still-existing reaction capabilities of the binder components and of the untreated silica component being utilised. In accordance with the invention, the residual fresh concrete is taken up by suitable devices with complete retention of its composition and conveyed to the binder preparation plant, being brought into a predetermined state of moisture and a substantially crumbly condition and used for preparation of a binder of a composition in accordance with specifications.

Abstract: Electrohydraulic regulating system for turbo machines, in particular steam turbines, using electrohydraulic compact drives for its valves, such as control, quick-closing or bypass valves. The packaged drive here comprises means for supplying electric power and 1) a system for receiving electric control signals and for converting the latter into corresponding hydraulic positioning or switching variables for a power-piston/cylinder system or a servomotor; 2) an autonomous hydraulic supply system with at least one fluid pump, fed from a hydraulic fluid tank and driven by an electric motor, and at least one hydraulic accumulator connected to the delivery side of the pump; 3) the hydraulic power-piston/cylinder system for the production of the valve adjustment as a function of the positioning and switching variables; the abovementioned three systems being integrated to form a packaged drive block arranged on the valve housing. The electrohydraulic conversion here takes place locally in each valve positioning drive. The linearisation of the valve characteristics is performed electrically or electronically by means of position set point entry in a forward-path control element ahead of the position controller. The master controllers for power and speed of rotation act via a transfer circuit. The master controller for the pressure ahead of the turbine acts via a transfer circuit in relation to the power or rotational-speed controller. <IMAGE>

Title: Arrangement for clamping or unloading workpieces, to be used in combination with a machine tool
IPC: B25B5/06
Filed: 1983-03-17
Abstract: A machine-tool workpiece pallet, traversable between a clamping station and a machining station, carries a work-holding fixture to which at least one pressure-medium connection (19) for admitting pressure to the clamping device is allocated at the clamping station.   A locking and coupling device (11) having the pressure-medium connection (19) and a drive device (27, 30) is arranged at the clamping station. In its operative position, the locking and coupling device (11) locks the pallet (2) and produces a connection between the pressure-medium connection (19) and the allocated pressure-medium line (12) of the pallet (2), which pressure-medium line (12) leads to the work-holding fixture. In the inoperative position, the pallet is released. After the pallet (2) with a machined workpiece arrives in the clamping station, a locking and coupling signal (s) actuates the drive device (27, 30). A regulating signal (t) effecting the discharge of pressure medium from the work-holding fixture is derived from the transfer movement, then taking place, of the locking and coupling device into the operative position. After the removal of the machined workpiece and the mounting of a new workpiece, a clamping signal switches the pressure-medium supply to feed. If the new workpiece is clamped, an unlocking and uncoupling signal (u) actuates the drive device, and the locking and coupling device is transferred into the inoperative position. <IMAGE>

Patent DE-3338059-A1 (DE)
Title: Fuel supply device
Inventor: HEIDEMANNS ROLF PETER
IPC: F02M17/09
Filed: 1983-10-20
Abstract: A fuel supply device for mixture-compressing internal combustion engines is proposed, in which the pressure differential of the extracted air required for metering of the fuel quantity can be controlled. The device comprises a fuel metering device and a vane cell pump for generating a carrier air flow, which delivers the fuel through feed lines into the intake pipe of the internal combustion engine. A control valve designed as a differential pressure valve influences the pressure of the air at the fuel outlet point and thereby the differential pressure for the fuel metering. The differential pressure valve has a diaphragm, which on the one hand is acted upon by the air pressure upstream of the throughflow aperture of the differential pressure valve which prevails in one duct section, which is connected to the main air duct. On the other hand the diaphragm is acted upon by the air pressure which prevails in the carrier air duct downstream of the throughflow aperture and in addition by a force of one or more bimetal springs which can be varied as a function of engine parameters. These springs are located in the heat radiation area of a heat accumulator, one side of which faces an insulating shell. A chamber, which is partially evacuated by the intake pipe pressure is located between the shell and the housing of the differential pressure valve.

Title: Method for temporal smoothing of a digital music signal in a computer-controlled device with analog-action music keys
Inventor: SCHADE GUENTER DIPL ING
IPC: G10H7/00
Filed: 1984-02-14
Abstract: Improvement of a method for electronic music generation     - by means of analog-action music keys,   - by means of a minicomputer operating in real time,   - by means of digital sound generation, - a multiplicity of different waveforms being stored in a common, continuously addressed memory, - each instantaneous sound signal value is formed through multiplication of a sound signal specific volume value by the current waveform value, - these instantaneous sound signal values are added together cyclically for all sound signals, - and the respective sum, i.e. the digital music signal, is converted via a digital-analog converter into the analog music signal. The improvement lies in the temporal smoothing of the digital music signal. This temporal smoothing can be advantageous on the whole because the digital-analog converter then has more time to settle. It is implemented by adding together the instantaneous sound signal values repeatedly and in cyclic succession in each case to form a sum.
