Title: Method and device for testing the dynamic water resistance of lubricants
Inventor: PETRIK MANFRED DIPL PHYS DR IN
IPC: G01N33/28
Filed: 1987-01-22
Abstract: In a method of determining the resistance of lubricants to flowing water at a particular temperature, the lubricant is exposed to being washed out by the water for a particular time and the loss in weight is determined as a measured quantity. To improve the method and for the purpose of easier manageability, it is proposed that the lubricant is applied as a coating to the surface of a test piston. The latter is then immersed in a water bath and rotated at a certain speed per unit time.

Title: Cutting-off arrangement for a pipe, a section bar or the like continuously running out of a production installation
Inventor: ZELLER KARL-HEINZ
IPC: B23D25/04
Filed: 1987-06-05
Abstract: It is known to provide on a continuously running pipe-welding installation a cutting-off unit which is displaceable parallel to the pipe, is brought during the cutting-off to the running speed of the pipe to be cut to length and is returned after the parting cut is made. In the process, the cutting-off unit is firmly clamped to a point of the pipe which cannot be exactly determined and is carried along by the pipe while the parting cut is being made. However, the lengths of pipe section are inexact. Since a certain pipe length continues to be produced during the return of the cutting-off unit, relatively short lengths of pipe section cannot be produced. The invention provides for a second cutting-off unit 13 to be arranged at the side of the pipe 11 to be cut to length remote from the first cutting-off unit 12. The second cutting-off unit 13 and the first cutting-off unit 12 come into use alternately. The second cutting-off unit 13 cuts off a pipe piece when the first cutting-off unit 12 returns into its initial position, and vice versa. The cutting-off units 12, 13 are driven in synchronism with the continuously moving pipe 11 by separate drive motors 17. They are controlled by an electronic measuring and control device 20 which is interconnected with a sensor 19 sensing the running speed of the pipe 11 to be cut to length. This permits precise cutting-to-length of the pipe 11 and short lengths of pipe section can also be obtained. <IMAGE>

Title: Method for carrying out a test and acceptance of an electronic device
Inventor: CORDELL STEVE
IPC: G01R31/3183
Filed: 1987-11-06
Abstract: Self-test mechanisms in flight and safety-critical devices must be carefully tested and accepted. In present-day practice, improper methods are used in order to accept these mechanisms. The only permissible method of accepting a device is if the device is under actual operating conditions, i.e. inter alia, that the housing must be closed or the acceptance must take place in an environmental chamber. Methods which prove the detection of the most elementary faults, e.g. the separation of a pin from an integrated circuit, are not effective in modern circuits with thousands of gates. In order to solve the problems of the prior art, individual circuits of a circuit can be called up individually or in different combinations by building in components provided with known faults. After careful analysis of the fault types of the circuit, the satisfactory components can be replaced by the components provided with known faults, and the fault-detecting capability of the self-test mechanism can then be tested under operational conditions. In order to reduce the reequipment time, several such components provided with faults can be simultaneously inserted. In order to test and to accept the self-test mechanism at operating extremes of temperature and voltage, components provided after intensive analyses with faults and weaknesses can be ... into the circuit ...

Patent DE-3738190-A1 (DE)
Inventor: HIRSCHEK HERWIG DIPL ING
IPC: D01G15/46
Filed: 1987-11-10
Abstract: The invention relates to a cross-lapper (1) with at least two rotating conveyor bands (6, 7) and at least two carriages (4, 5) moved in a reversing manner and accelerated at the reversal points of their travel. To influence the pile thickness in a controlled manner, the band running speed and the travelling speed of the carriages are uncoupled from one another between the acceleration phases and are set differently in relation to one another. For this, there are separate drives (14, 15), especially servo-drives, at least one of which has a freely programmable control (15, 13). In the travel zones between the reversal points of the carriages (4, 5), a constant or variable speed difference in relation to the conveyor bands (6, 7) is produced, this being expressed in a change in the deposited pile thickness (9). When the carriages (4, 5) move faster, the pile becomes thicker, and with the opposite speed difference the pile thickness becomes smaller.

Title: Process and appliance for thermal treatment of contaminated bulk materials
Inventor: STALHERM DIETER DIPL PHYS DR
IPC: F23G7/14
Filed: 1987-11-19
Abstract: The invention relates to a process for the thermal treatment of contaminated bulk materials (bulk solids), in which the contaminated bulk materials are heated, in a roasting treatment stage, preferably in one or more rotary kilns, in direct heat exchange in countercurrent with hot heating gases, preferably flue gases, and then, as purified bulk material, are available for further use, and in which the gases driven off during heating from the hot bulk material are subjected, together with the heating gases, and after dry dedusting, to afterburning and the exhaust gases (off-gases), after optional final cleaning, are discharged into the environment. It is proposed according to the invention that the separated fine dusts from the dry dedusting process are then heated, in an indirectly heated oven, to at least the treatment temperature of the remaining bulk materials and then, if appropriate, admixed thereto. An appliance for carrying out the process is also described. <IMAGE>
Patent DE-3742592-A1 (DE)
Inventor: HENNING MANFRED DIPL ING
IPC: G01D18/00
Filed: 1987-12-16
Abstract: In for instance an i.c engine wherein an adjustable position (8) sets the idle position of a throttle valve lever (6), the position signal reported back by the throttle valve 2 may vary from one example of the carburettor to another. To remedy the matter, the reported-back position signal (a) of a controller (valve 2) actuated by a positioner (8) is adjusted by a method wherein:   a) the positioner (8) is set to give a specified reported-back position signal (SE) b) with the positioner held fast at this setting the controller (2) is adjusted mechanically to provide a specified output (air flow). c) during subsequent operation, position signals (S,  alpha ) from positioner (8) and controller (2) are reported back to a signal processor (12) by potentiometers (9, 10). The processor (12) stores a graph of S against  alpha  (Fig 5). If the measured value of  alpha falls outside the allowable range given by the graph for the measured value of S, then  alpha  is adjusted to bring it into the range.   By more accurate correlation of the signal values better operation of the engine can be achieved and, furthermore, it becomes possible to determine, for control purposes, whether the positioner (8) or a human operator is actuating the throttle. <IMAGE>

Title: Closure, in particular cylinder lock for furniture
Inventor: GROENWOLDT ROLF
IPC: E05B29/04
Filed: 1988-02-10
Abstract: The invention relates to a closure, in particular a cylinder lock 1 for furniture, having a cylinder core 4 which is swivellable between two alternative swivelling positions, the locking position and the open position, and is received in a cylinder housing 3. Over a region of the swivelling movement of the cylinder core 4, a bolt carrier 9 is only axially movable with respect to the cylinder core 4 and, over a further region of the swivelling movement, the bolt carrier 9 can be swivelled, together with the cylinder core 4, into the locking position. For this purpose, the cylinder core 4 and the bolt carrier 9 are provided with a sloping surface 10 and supporting surface 11 respectively. By means of a solution according to the invention, a housing construction is possible without radially outwardly open through-holes. Furthermore, coarse constructional tolerances can also be permitted since the surfaces bearing against each other, namely the sloping surface 10 and the supporting surface 11 are always held in contact with each other by a spring 14. The closure can be used both with and without a closable cylinder core and can also be used, in connection with a bolt, for securing flaps and with a bolt for securing sliding doors. <IMAGE>

Title: Combined drive for bicycle dynamo and tachometer
Inventor: NIEDERLEITNER GEORG
IPC: B62J6/06
Filed: 1988-03-05
Abstract: Bicycle dynamos usually have a fluted friction wheel which is pressed against the rotating side wall of the bicycle tyre during use of the dynamo. As is known, such drives have an unfavourable efficiency and are unreliable, in particular in bad weather and in the event of a diminishing contact force of the dynamo, so that satisfactory illumination is no longer available. The novel combined drive is intended to increase the road safety and allow energy-saving dynamo operation as a result of a high availability of illumination and a noticeable annular lateral reflection surface. A novel toothed ring 6 is attached to the wheel spokes 3, in the toothing 2 of which toothed ring 6 the pinion 1 which is fastened on the dynamo shaft 7 in place of a friction wheel engages in a positive-locking and frictionally engaged manner. Uniform tooth engagement between the pinion 1 and the toothing 2 is achieved by means of a roller 5 which is arranged concentrically on the pinion 1 and runs along the non-toothed part of the toothed ring 6. Slipless drive for bicycle dynamos which, at the same time, can also be used as a drive for tachometers. <IMAGE>

Title: Wheel bearing arrangement
Inventor: KOSCHINAT B HUBERT
IPC: B60B27/02
Filed: 1988-03-18
Abstract: The invention relates to a wheel bearing arrangement for a vehicle wheel in which the wheel hub is rotatably received on the axle pin of a wheel axle by means of a wheel bearing which is constructed as a double tapered roller bearing and has at least one outer ring and at least one inner ring between which the bearing rollers are arranged and which are held between stop shoulders of the wheel hub and/or the wheel axle and/or an axle nut and/or on components which are fixed thereon in an axially non-displaceable fashion, and with a disengagement preventor for the wheel. In order to ensure that protection against disengagement is provided in every case, it is proposed with the invention that the outer ring which is possibly divided from the wheel hub itself and possibly divided into two outer rings have a radially inwardly pointing collar between the adjacent bearing rollers, the inner diameter of which collar is smaller than the largest outer diameter in each case of the axially outer inner ring or of a normal axle nut.

Title: Drill with projecting cutting edges
Inventor: HAAGE MANFRED
IPC: B23B51/02
Filed: 1988-03-19
Abstract: Drills with projecting cutting edges are known, being used to produce undercut drillholes. When making the drillhole, however, the projecting lateral cutting edges cause the drill to be inclined to yield laterally, so that drillholes with undesired curvature frequently result. In order to obtain centring during the drilling operation, only one projecting lateral cutting edge and, located opposite the latter, a correspondingly projecting bearing surface are provided on the drilling head. Radial forces acting on the lateral cutting edge are thus no longer able to cause an undesired lateral yielding of the drill.
