Patent DE-3504623-A1 (DE)
Title: Device for detecting active and/or reactive current and/or their power in an inverter with predetermined input DC, particularly a pulse-controlled inverter
Inventor: BRAUN MICHAEL DR ING
IPC: G01R19/06
Filed: 1985-02-11
Abstract: In an inverter, the switching signals for the inverter switches determine the phase angle, frequency and amplitude of the output voltage. Measurement values (iU, iV, iW) corresponding to the phase currents are pulse-width-modulated by means of switches (MU, MV, MW) which can be operated by the same switching signals. The resultant instantaneous values of the phase power are added (7), if necessary, to the total active power. The sum signal can be weighted with the reciprocal value of the voltage modulation of the inverter by a curve-generating element (8), so that a signal (IW) proportional to the active current is produced. In the same manner, the reactive current can also be determined by means of switches (BU, BV and BW) if only the phase of the phase current measurement values is shifted by  pi /2. <IMAGE>

Title: Process for cleaning plastics wastes
Inventor: BUZGA HEINRICH ING GRAD
IPC: B29B17/02
Filed: 1985-03-09
Abstract: The present invention relates to a process for cleaning contaminated plastics film wastes which are precomminuted to approximately the size of a palm of a hand to a particle size and a degree of purity such as to permit regranulation to form a high quality product. The film particles are moved, suspended in high dilution and at high flow rate of the suspension, past product retainers, the cleaning being able to take place by simultaneous friction against the walls of a narrow gap of a rotary mill having a rotor and a stator. In the latter case the suspension is fed axially and discharged radially under acceleration with the aid of radially acting transport elements arranged on the rotor. By additional arrangement of a cutting head, it is possible to comminute the wastes directly before cleaning. <IMAGE>

Title: Motor housing, especially for a submerged pump
Inventor: MABILLOT CHRISTIAN
IPC: F04D13/08
Filed: 1985-04-09
Abstract: The invention relates to a motor housing which consists of two parts, preferably for a submerged pump. In order to be able to produce the housing as cheaply and simply as possible, with all the required properties such as corrosion resistance with respect to the fluid being conveyed, good conductivity, low weight and mechanical strength, the invention provides that only the one of the two housing parts consists of a corrosion-resistant material, while the other is produced from a different material and is at the same time completely covered by a cap, which closes it in a sealed manner and consists of a third material. In consequence, this second part does not need to have all the required properties such as thermal conductivity and corrosion resistance, and can thus be produced cheaply.

Title: Hydraulic excavator with adjustable track-laying gear
Inventor: SCHAEFF HANS
IPC: E02F9/02
Filed: 1985-09-28
Abstract: Track-laying vehicle with a chassis which has adjustable track-laying units in order to adjust the track width. The track-laying units are connected to the lower carriage via parallelogram-forming pairs of link arms, which can be pivoted about horizontal axes, as simple adjusting and driving means for changing the travel gear between a widened operating position and a narrower transport position. In the approximately horizontal position of the link arms, the track-laying units are furthest away from the lower carriage and are secured by stop and locking means. In order to reduce the track width, the locking is released so that, as a result of the swivelling movement of the link arms, the lower carriage is simultaneously lowered with respect to the track-laying units and the track-laying units move closer to the lower carriage.

Title: Process and apparatus for producing ceramic products in bulk
IPC: F27D3/00
Filed: 1985-12-20
Abstract: In a process for producing ceramic products in bulk, shaped parts are formed from ceramic material, are then dried in a drying unit and fired in a continuous furnace. For this purpose, a conveying device for the drying unit is charged with the shaped parts, to be precise with a disc-like arrangement of the shaped parts such that in each case two discs are spaced apart from each other and an interspace, running approximately transversely to the conveying direction of the conveying device and extending over the entire transverse extent of the shaped-part discs, is thus formed. The drying medium is guided along the interspace, transversely to the conveying direction. The shaped-part discs are guided on the conveying device to the continuous furnace, the streams of firing heat being guided through the interspace.

Title: Winter sports apparatus with two skis which can be pivoted about parallel lengthwise axes
Inventor: FELDTAENZER ERICH
IPC: A63C5/03
Filed: 1986-01-04
Abstract: The invention relates to a winter sports apparatus with a platform 1 supporting the user, which platform can be pivoted about a lengthwise axis parallel to the plane thereof and is mounted at the tip of one front and one rear triangular connecting plate 2, these having at their ends, in each case, a bearing for parallel skids 3 each of which can be pivoted about a lengthwise axis parallel to the plane thereof, the planes E of rotation of the triangular connecting plates 2 being inclined obliquely forwards by the same angle to the vertical in the movement direction F. As a result of the design according to the invention of the connecting and pivot mechanism, a greater angle of tilt of the skis is achieved for this winter sports apparatus (also referred to as a "ski-surfing apparatus") together with, during tilting, a compression of the insert edges by reduction of the distance between the skis and, at the same time, better guidance of the skis by a longitudinal displacement of the skis relative to each other, so that the ski which is higher in relation to the ground is pushed forwards. As a result, the movement properties and utility of the winter sports apparatus are improved with a simple and operationally reliable design. <IMAGE>

Title: Switch for command units and signalling units, machines or the like
Inventor: HERRMANN JOSEF DIPL ING
IPC: H01H13/84
Filed: 1986-01-31
Abstract: The switch for command units and signalling units, machines or the like has a switch housing (1) in which a switching element (3) is arranged. A securing part (4) having at least one feel element (24), which is constructed as a profiled part, is provided on the switch housing (1) in the movement path of the hand of a person who is operating the switching element (3). Since the operator senses the feel element (24) during operation of the switching element (3), said operator can detect which switch is being operated without having to look at it, while touching the securing part. In this way, it is possible reliably to prevent an incorrect switch accidentally being operated, which could lead to disturbances (defects) of the apparatus or to an accident risk. <IMAGE>
