Patent DE-3806725-A1 (DE)
Title: Device for edge-mill charging and discharging
Inventor: SOGL RUPERT DIPL ING
IPC: B02C15/14
Filed: 1988-03-02
Abstract: Using this edge-mill charging system for wet edge mills and pug mills having drive from below, it is possible continuously to charge the entire circular ring surface of the edge-mill grinding surface (10) with material to be mulled. The low height of the piled-up material ensures excellent grinding, kneading and mixing while at the same time increasing the capacity. The power requirement will now be uniform, and the abrasion of the runner rings (6) and of the grinding track plates and grid track plates (10) will decrease. The discharging of material is achieved with the collecting plate (16) running counter to the vertical shaft (4) and with the cylindrical, faster rotating stripper (19). Figure 1 shows a plan view of such an edge mill with the conveyor belt (1) which feeds the material, the conveyor belt (2) and the material-charging belt (3) which throws the material to be mulled directly onto the grinding track (10). In addition, material distributors (12) are provided. <IMAGE>

Title: Inspection lamp for the illumination of hollow spaces
Inventor: WILLING ACHIM DR ING
IPC: G02B25/02
Filed: 1988-03-26
Abstract: An illumination device for the visual monitoring of objects is proposed, in which a partially transparent mirror is arranged transversely in the beam path of a light source to direct the radiation onto the object. An observer beam path is directed onto the object via the side of the partially transparent mirror facing away from the light source. Furthermore, a light trap is provided, which is arranged in such a way that it absorbs the remaining radiation passing through the mirror and not directed onto the object or reflected at the surface of the mirror facing away from the object. <IMAGE>
Patent DE-3810438-A1 (DE)
Title: Cylinder store for magnetic-optical or optical data storage and reproduction
Inventor: KOENIG WILHELM
IPC: G11B7/0025
Filed: 1988-03-26
Abstract: The configuration of the cylinder store permits use of the entire available information surface, with a constant rotational speed of the cylinder. Due to constant flow conditions on the outer and inner surface of the cylinder, a higher reading and programming reliability can be achieved. The design of this cylinder allows a more stable configuration, which permits less expensive processing. For the information density per unit area this has the result that no increase in the spacing of the information markings has to be expected in the running direction of the track on account of rotational speed tolerances which are required due to +/- accelerations.
Patent DE-3813774-A1 (DE)
Title: Radial piston pump
Inventor: LISKA GEORG
IPC: F04B1/04
Filed: 1988-04-23
Abstract: In a radial piston pump, caps (7) screwed into the pump housing (1) close cylinder bores (6) in which delivery pistons (5) move. The caps (7) have a valve seat (20) on which a flat spiral spring (21) bears in sealing fashion. A plurality of bores (25) lead from the piston pressure spaces (26) into a groove (22) which extends semicircularly along the inner face of the flat spiral spring (21). The valve seat (20) is designed as narrow as possible, so that the outlet pressure acting in an annular space (19) only pressurises a small differential area. Since the opening pressure for the flat spiral spring (21) is relatively low, the high pressure peaks and thus the high pressure loading of the pump can be reduced. <IMAGE>

Title: Electrode laser catheter
Inventor: WEBER HELMUT DR
IPC: A61B18/24
Filed: 1988-05-02
Abstract: Cardiac catheter in the form of a tube which is provided with two electrodes in the vicinity of its distal end as a probe for locating pathological, e.g. arrhythmogenic, areas, an axially displaceable light guide whose tip can be used as a radiation source for the areas being arranged in the lumen of the tube. Such cardiac catheters are to be developed further such that repositioning of the cardiac catheter is unnecessary after locating a source of arrhythmogenic disturbance for application of the laser light. This is achieved in that   - the tube 2 is provided in the region of its distal end with at least two slots 12 essentially extending in the longitudinal direction, - the two electrodes 14, 16 are arranged at the front ends of two elongate tubular sections 25, 26 formed by the slots, and the lumen 4 of the tube 2 preferably tapers conically from the inner end of the slotted region in the direction of the distal end, the light guide 6, 8 being axially advancable for spreading of this conical constriction 22 and hence of the elongate tubular sections 25, 26.   <IMAGE>

Title: Low-loss circuit for at least one switchable valve
Inventor: WILLIMANN ADRIAN
IPC: H03K17/0814
Filed: 1988-05-06
Abstract: For self-commutated multi-quadrant converters such as those used for three-phase drives with controlled speed, low-loss circuits (4) of reverse-conducting GTO thyristors (V1, V2) or power transistors are provided which have versatile uses. Each two switchable valves (V1, V2) form a valve branch pair of the converter, it being possible for the A.C. voltage for the three-phase drive to be picked up on an A.C. terminal (3). In order to discharge disconnection-load-reducing capacitors (C1, C2) connected in parallel with the GTO thyristors (V1, V2) via disconnection-load-reducing diodes (D1, D2) after the load current has been taken over by the GTO thyristors, a ringing circuit (C1, V1, D2, Tr, T1; C2, Tr, T1, D1, V2) is provided for each switchable valve, having a transformer (Tr) in series with a ringing thyristor (T1). The ringing thyristor (T1) is connected to a control circuit (6) which automatically triggers the ringing thyristor as a function of the anode-cathode voltage of the latter. By means of the transformer (Tr), a portion of the energy stored in the disconnection-load-reducing capacitor (C1, C2) is fed back via an uncontrolled bridge-connected rectifier (D3-D6) to a D.C. voltage source (1, 2) of the converter. <IMAGE>

Title: Washing machine with an integrated water-softening device
Inventor: STAMMINGER RAINER DIPL PHYS DR
IPC: D06F39/00
Filed: 1988-06-09
Abstract: Excessive brine is to be prevented from running into the appliance housing during stocking-up with salt. In known washing machines, the salt vessel possesses a brine-collecting space which is provided at the bottom with a run-off orifice and which is connected to the lye pump via a hose line. Under these conditions, brine can pass into the tub and cause corrosion damage. In the washing machine according to the invention, overflowing brine is conveyed directly into a chamber of a reflux container and from here directly into the open via the waste-water hose elbow. The reflux container (1) is subdivided by a partition wall (7) into two chambers connected to one another in flow terms. The first chamber is connected to the run-off system (3) and the second chamber is connected to the brine-collecting space (12) of the salt vessel (13) via a connection piece (10) having a non-return valve (11). Waste water and/or brine pass into the discharge via the waste-water hose elbow (9) of the second chamber. The washing machine according to the invention is suitable for use in households. <IMAGE>

Patent DE-3824569-A1 (DE)
Title: Apparatus for the production of a fibre web
Inventor: PARRINGTON ALLAN P
IPC: D04H1/60
Filed: 1988-07-19
Abstract: A licker-in and feed mechanism produces a supply of individual short fibres which follow the rotation of the licker-in. These fibres are deflected in the form of a stream from the licker-in by means of a plate which is arranged parallel to the licker-in. A conveying screen catches the fibre stream and accumulates it to form a web, without the use of a high-pressure airstream, in order to doff the fibres from the licker-in or catch the fibres on the conveyor. Furthermore, the housing for the apparatus is open, so that no seals are present in order to compress the web after it has been produced. A feed trough in the vicinity of the licker-in can be used in order to admix other particulate materials (fibres or granulates) with the main fibre stream, and a conically tapering deflecting plate can separate the constituents of the stream of mixed fibre/particulate materials into layers in the finished web which differ from one another in their particle weight (Figure 1). <IMAGE>

Title: Electric flow heater
Inventor: BAADER HELMUT DIPL PHYS DR
IPC: F24H9/20
Filed: 1988-09-09
Abstract: A multi-pole operational switching device having a safety switching device with all-pole interruption of the heating circuit, for an electric flow heater, the operational switching contact device being actuated by means of a water switch reacting to difference in pressure and the safety switching device being triggered when excess pressure or excess temperature occur. The operational contact device (7, 7') and the safety switching device (10, 10') are united to form a single switching unit or constructional unit. A common double-spring contact arrangement (20, 20') is provided for the two devices and constructed to be U-shaped. The one U-leg of this double-spring contact arrangement carries the mobile contact (7) of the operational switching contact device and the other U-leg the mobile contact (10) of the safety switching device. In order to ensure a determinable basic contact pressure for the operational switching contact device, the closing position of the mobile contact (7) (make contacts (main, operating contact)) of the operational switching contact device is secured in a positively locking manner by means of a lever mechanism (22) and of a pivoting lever (25) coupled thereto. To interrupt or neutralise this closing position, the lever mechanism (22) is at first relieved by means of the water switch, and a remaining power flux of the moving contact (7) with the contact (7') is subsequently overcome by shifting (throwing) the pivoting lever (25). <IMAGE>
