Title: Quick-change running and fixing float
Inventor: TAAKE SIEGFRIED
IPC: A01K93/00
Filed: 1987-05-13
Abstract: The technical problem is how to provide a float/quill on fishing tackle which is bound with fishing hook, cast (leader) and sinkers or how to convert, when there is a change in the weather or in the case of dusk/poor visibility, ready-bound fishing tackle by changing the float such that it is adapted to the weather/visibility without damaging, by untying/cutting off, those items, such as cast, fishing hook, sinker, etc., which are bound beneath the float. A further problem is how to convert the type of fishing, with the lowest possible outlay, from ground fishing/running float to fishing at a specific height/fixing float or vice versa without damaging anything.   The "quick-change running and fixing float" solves all these problems in one. By means of just one float, it permits 1. fitting and quick changing by a quick-change running eyelet, 2. use as a running float for ground fishing by (quick-change) running eyelet and 3. use as a fixing float by fixing means for the fishing line for fishing at a specific depth. The quick-change running eyelets on the float permit an endless cord to be threaded into, and run freely through, the eyelets, with the result that, without expending time and equipment, the "quick-change running and fixing float" can, in seconds, be fitted on any ready-bound fishing tackle, or exchanged. The various possible fishing applications of the "quick-change running and fixing float" can be gathered from the drawing and from the above text (items 1 and 2). <IMAGE>

Patent DE-3727236-A1 (DE)
Inventor: FAHJE HENRY
IPC: C02F3/28
Filed: 1987-08-14
Abstract: The fixed bed loop reactor for ascending flow consists of a reactor vessel (1) with a vessel base (3.1), sieve plate (2), jacket (1.1) and roof (1.2) as well as a central pipe system (4) penetrating the reactor (1) in the area of the axis or centre (z-z) of the latter. The annular space between the central tube system (4) and the jacket (1.1) is filled with the porous fixed bed (6) consisting of the bed of support material (6a) and the biomass adapted to it. The fixed bed (6) is supported on a sieve plate (2) and in the area of this sieve plate there is a funnel-shaped broadening (4.1) of the central tube system (4). In this manner, apart from reducing the bearing area for the support material (6a) or the fixed bed (6), an increase in the pressure loss in the sieve plate (2) is achieved and, consequently, good distribution, through the total cross-section of the reactor, of the fluid to be purified which flows in from below. Additional features or advantages: concentric connection pipes (r12, r22) integrated with the channel wall system (4), a high concentration of biomass on the support material. <IMAGE>

Title: Method of water-jet cleaning surfaces, for example of buildings
Inventor: NAGY HUGO
IPC: B08B3/02
Filed: 1987-11-17
Abstract: The invention relates to a method of water-jet cleaning surfaces, for example buildings, in particular for removing dirt adhering to stone external surfaces, for example to porous limestone surfaces of room delimiting walls, with the aid of overpressure water jets. According to the invention, water jets with an overpressure of at least 5 bar are used for cleaning, and the speed of the water jets is increased to at least 1.5 times with narrowing of the flow cross-section. The accelerated water jets are divided into trickles by impacting, the - expediently spherical - water droplets divided into trickles are guided onto the surface to be cleaned and expediently into the pores of the surface.
Patent DE-3743500-A1 (DE)
Inventor: MORGENSTERN J PROF DR
IPC: G01D5/20
Filed: 1987-12-22
Abstract: The invention relates to an electromagnetic device for inductively measuring attitude. A known device of this type provides coils (1,2,3) wound around a ferrite core cross, to which an alternating voltage is to be applied. The magnetic fields are inductively detected at a limited distance by means of measuring probes. Changes in direction between the probes of the receiver and of the transmitter have a highly distorting effect on the measurement result. The invention eliminates both the disadvantage of the measuring distance only being short and the disadvantage of the superposition of noise voltages in the case of changes in direction by means of the fact that the probe, having several winding axes (4,5,6) has turns diameters of the coils which are greater with a greater distance from the centre of the probe than with a shorter distance from the centre (7). This provides the possibility of filling out the entire probe volume with turns. Surprisingly, an almost complete independence of the direction of the probes with respect to one another is found in distance measurements.

Title: Hydraulic brake system
Inventor: SCHONLAU JUERGEN
IPC: B60T8/44
Filed: 1988-01-12
Abstract: A hydraulic brake system for motor vehicles with a master cylinder (37), wheel cylinders, a vacuum brake booster (2) and a control module for generating a controlled pneumatic pressure for the vacuum brake booster (2) is proposed. The vacuum brake booster (2) generates a controlled hydraulic pressure. By means of the controlled hydraulic booster pressure, an operating pressure is generated in the master cylinder (37) for actuation of the wheel cylinders of the brake system. This operating pressure acts by way of a passage (35) on a sensing piston (44). The said sensing piston (44) converts the operating pressure into a reaction force, which can be felt on the brake pedal. By means of the invention, an improved reaction force, great flexibility when fitting the brake system in vehicles of different types, a compact construction, a significant reduction of the hysteresis and a simplification of costly, conventional vacuum brake boosters are achieved. <IMAGE>

Title: Roller mower
Inventor: WIENEKE FRANZ PROF DR ING
IPC: A01D34/52
Filed: 1988-02-08
Abstract: Roller mowers, in particular having continuous blades, are damaged when foreign bodies, such as stones, pass through them; the blades become blunt as a result of the impingement on blades, and the teeth of blades bend. By separating the blade and segments and having a profiling of the blade which connects the individual teeth, the disadvantages can be eliminated. The configuration of the profiling also permits grinding of a toothed blade.

Title: Flat screen note display
Inventor: SCHENCK RAINER
IPC: G09B15/02
Filed: 1988-11-22
Abstract: Instead of a music book, the notes are displayed to a practising musician on a flat screen or liquid crystal display. The signal to move the notes forwards can be triggered after a preset time, or by manually activating a switch, or, if the elements of the musical performance are analysed, by the player reaching a certain point in the music. By inputting a page or serial number manually, any position in the musical notes can be displayed. A learning device, by which incorrect playing of a musical score is displayed to a music pupil, is also specified. The input notes are compared to the predefined notes by a note analyser or the music keyboard input. If a single note, or a pre-programmable number of notes, are played incorrectly, the analyser reports this on the screen by a separate signal, or by drawing attention to the wrongly played notes (different colour, flashing signal).

Title: Cylinder head with control disc for axial rotary engines with static cylinders operating on the spark-ignition principle
IPC: F02B1/04
Filed: 1988-12-12
Abstract: Instead of valves the cylinders (13) uniformly distributed on a cylinder pitch circle (25) concentric with the engine shaft (1) are controlled by a control disc (12) fixed on the engine shaft (1) so that for one revolution of the control disc (12) the pistons (11) perform 4 strokes. The control disc (12) rotates above the cylinders (13) sealed by rings (14) and controls the working cycle for each cylinder (13) with phase offset. By way of the air connection (4) and an annular inlet port (22) the air passes through the cylinder head (5) connected to the engine housing (10) into the inlet opening (21) of the control disc (12), from where it is led into the cylinders (13). The fuel passes through the fuel feed (2) into an annular fuel passage (3) and thence by way of an inlet valve (23) assigned to each cylinder (13) into an injection pocket (16) of the control disc (12), where it then emerges through a small bore (15) into the inlet opening (21). The ignition voltage is fed by way of the connection (20) to a concentric ignition ring (6).

Patent DE-3902907-A1 (DE)
Title: Device for supporting shafts of elongate machines
Inventor: GNAEHRICH ALFRED DIPL ING
IPC: B04B9/12
Filed: 1989-02-01
Abstract: In the case of hitherto known devices for supporting shafts of elongate machines, especially centrifuges, rotary drums, roller presses etc., transverse forces occur due to inaccuracies in alignment and/or non-uniform drum loading, and these forces have to be transmitted by the shafts to the rolling bearings and compensated for by the latter. These bearings are therefore exposed to relatively high non-uniform alternating loads and their service life is therefore relatively short even when their dimensions are relatively large. Moreover, the high alternating loads on the bearings generate an intolerably high noise level for the operating personnel. According to the invention, these disadvantages are eliminated in a simple manner by virtue of the fact that the rolling bearing (2) is built into a hydrostatic spherical plane bearing (3, 4, 8, 9) and that the bearings (2, 3, 4, 8, 9) are connected to pressure and lubricant lines (14, 31). <IMAGE>

Filed: 1989-02-13
Abstract: The washing machine is equipped with a conductivity measuring cell (24) which determines the electrolyte content of the pumped-off rinsing water, so that a decision can be made as to whether a further rinsing operation is necessary. The measuring cell (24) is arranged in a portion (20a) of the run-off line (20), in which there is still residual water from the rinsing operation after the pumping off. The conductivity measurement is carried out with the rinsing water at a standstill. The conductance of the fresh water which is fed to the washing machine and which has been measured by a further measuring cell (4), likewise with the water at a standstill, is used as reference conductance. <IMAGE>

Title: Lockable plug connector
Inventor: KEWITZ WERNER DIPL ING
IPC: H01R13/627
Filed: 1989-03-01
Abstract: The coding of plugs by means of a suitable design of the plug face and socket face is relatively costly. It can also no longer be changed retrospectively. It is proposed to provide the plug part with fixed coding in the form of at least one recess running over the insertion length, and to provide the plug socket with openings assigned to the position of the recesses, into which openings coding pins can optionally be pushed and locked. As a result of this refinement, it is possible to assign corresponding faces of the plug sockets to various faces of plugs, even retrospectively, by insertion of the coding pins. Use for plug connectors in telecommunications, especially for telephone devices. <IMAGE>
