Patent DE-3703988-A1 (DE)
Inventor: HESCHER MANFRED
IPC: G11B5/53
Filed: 1987-02-10
Abstract: For recording and reproducing broad band signals on magnetic tape, apparatuses with electromagnetic converters arranged on the circumference of head wheels or head drums are used. In order to define according to standards the magnetization range of each track, the electromagnetic converters have to be adjustable with very strict allowances in the radial, axial and circumferential direction of the head wheel or head drum and in their angular position. Known holding and adjusting devices allow such adjustments to be only imperfectly done or require too much space. The present holding and adjusting device is subdivided by slots located between both magnetic heads (8,9) and extending in the circumferential direction in such a way the spacing between the head gaps in the circumferential direction, their height relative to each other and the azimuthal angle of the head gaps can be adjusted by means of adjusting screws (16,22,23). The holding and adjusting device is particularly suitable for being arranged at the free end of a  piezoelectric deflecting device (2).

Title: Longitudinally variable connecting rod for brake calipers of disc brakes
Inventor: PRAHL FRANZ
IPC: B61H5/00
Filed: 1987-05-22
Abstract: The connecting rod for brake calipers of disc brakes which are provided in particular for rail vehicles has two head elements 1 and 2 to which brake caliper levers are to be connected. The head elements 1 and 2 are connected to one another so as to be adjustable by a screw bolt 6. A locking sleeve 13 is mounted on the screw bolt 6 in an axially displaceable but non-rotatable fashion and interacts by means of a locking toothing 16 with the head element 1 through which the screw bolt 6 engages with a thread-free portion. A compression spring 15 loads the locking sleeve 13 in the closing direction of the locking toothing 16 and thus spreads the two head elements 1 and 2 apart from one another. In order to adjust the connecting rod, all that is necessary is to apply a degree of torque, counter to the force of the compression spring 15, sufficient to disengage the locking toothing 16, the connecting rod can thus be used as a mechanical emergency release device. The locking toothing 16 permits very precise longitudinal adjustment of the connecting rod by means of very small pitch increments. <IMAGE>

Patent DE-3739328-A1 (DE)
Title: Gravity motor
Inventor: BIERGANNS HANS WERNER
IPC: F03G3/00
Filed: 1987-11-20
Abstract: Gravity motor in which weights are displaceable by means of an auxiliary force on a hub, wheel or disc fixed to a shaft and the displacement device can be controlled in such a way that there is a weight or lever-arm difference between one side of a vertical passing through the axis of rotation and the other side. The displacement device in this arrangement is of double-acting design and the displacement travel of the device is equal to or greater than the distance between the maximum radial outer position of the weights and the axis of rotation, and the weights can thus be displaced in such a way that they always produce a positive rotational force (Fig. 2). <IMAGE>
Patent DE-3741338-A1 (DE)
Inventor: RUMP HANNS
IPC: G01S15/74
Filed: 1987-12-07
Abstract: In a process for measuring distances by means of pulse transit times, in particular by the pulse-echo transit time method (working by echos) or by the pulse-reflex transit time method working by transponder, using waves having a given velocity of propagation, in particular ultrasound waves, a pulse packet of given length and frequency is generated, transmitted, and received as an echo or a reflex after a time-interval depending on the transit time. The positions of a plurality of received pulse packets (echos or transponder reflexes) on the time axis are compared; for this purpose the positions of a certain number of pulse packets on the time axis must be comparable within a given tolerance. The mean value of the results obtained is calculated. The individual measurements must be made in the fastest possible sequence, because the arrival of a response pulse (pulse packet) triggers a new measurement which, if a response pulse is not received, is limited to a maximum time-interval corresponding to the maximum possible measurement range.
Patent DE-3800019-A1 (DE)
Title: Apparatus for the long-term tending, in particular, of plants, and process for the production of the apparatus
Inventor: BLOCK HUBERT K
IPC: A01G27/02
Filed: 1988-01-02
Abstract: The invention relates to an apparatus for the long-term tending of plants, as well as the production process of the apparatus; it is in the form of an annular tank. Stoppers and parts for preventing the through-passage of water, such as mechanical elements for closing off water outflows and the like are, at the present time, intended to prevent the subatmospheric pressure, which is cancelled upon the introduction of water, and the water outflow occurring as a result. Annular tanks operating on a subatmospheric-pressure principle are currently manufactured as individual injection-moulded parts and are completed by bonding them together adhesively. This is expensive and susceptible to malfunctions. The present innovation achieves the object of the invention by manufacturing the annular tank (1) in the "stretched-out" state by blow moulding. For use, the flexible (2, 2<a>) apparatus (1) is arranged between the outer pot and the plant pot - the "toothed" tank ends (3<a>, 3<b>) interengaging (bridging two pot sizes). The centrally arranged filling channel (5) is flanked by two ventilating and venting channels (4<a>, 4<b>) for a problem-free, symmetrical supply of the tank halves (14) with nutrient fluid. A screen (8) which is shrunk in in the upper, widened filling-channel end (7) protects the tank (1) from foreign bodies. The apparatus manages without any adhesive bonding and filling methods which are susceptible to malfunctioning. It can be stacked and stored - in the "stretched-out" state - in a very confined area. <IMAGE>

Title: Clamping and adjusting device for the fixed tool holder of thread-rolling machines
Inventor: JUNG CLEMENS DIPL ING
IPC: B21H3/06
Filed: 1988-01-15
Abstract: The adjustment and setting of the tool holder (jaw cage) with cap screws and set screws is involved and time-consuming. To facilitate and accelerate adjustment and conversion to different workpiece dimensions, hydraulic cylinders, each in the form of a hollow-piston cylinder (9) or swinging clamp (18), are provided as locking devices. The downtimes of thread-rolling machines by means of which it is also possible to roll circumferential profiles other than threads into round pins or bolts, are considerably reduced by means of the new clamping and adjusting device (1) since, in particular, it is possible for the jaw cage (3) together with the fixed rolling jaw (4) to be removed from the machine at the top as a complete unit and preset at another workstation while the readjustments to the machine can be carried out independently. <IMAGE>
Patent DE-3804226-A1 (DE)
Title: Flexible clothes hanger
Inventor: TOLLKIEN RALF
IPC: A47G25/40
Filed: 1988-02-11
Abstract: The invention relates to a flexible clothes hanger for any outer garments, and also for skirts. Said clothes hanger makes it possible to introduce the brought-together branches of a hanger through the collar of an outer garment. When the branches, pressed together by one hand, are released, they spread open immediately, with the result that the garment is already hung on the hanger. The removal of the garment is effected equally simply by pressing together the hanger branches, whereby the garment is immediately freed without an additional manipulation being necessary. By designing an individual hanger as one element of an assemblable, integrable or compact multi-hanger system, this hanger can be employed in a space-saving manner. In this case, an angle of inclination, bend or flexion of the hanger branch(es) differing slightly from the perpendicular (by means of structurally fixed angle bends of the hanger branches or (and) by arranging the individual hangers in the hanger system at a given angle) must be used in order that, in the compound hanger structure, when the hanger branches are pressed together they do not strike the next hanger branches below or the centre piece of the next hanger below.

Patent DE-3811354-A1 (DE)
Inventor: LEX ERNST DIPL ING
IPC: B60K11/08
Filed: 1988-04-02
Abstract: There is a ventilation grille for an air flow directed from the outside inwards, in which an outer and a central row 6, 8 of slats 7, 9 are staggered in relation to one another, in which the slats 11 of an inner row 10 lie opposite the slats 7 of the outer row 6, and in which the cross-section of the slats 11, 9 of the inner and of the central row 10, 8 has the shape of a V. In this connection, it is desirable that water which passes through the outer slats and is also not removed by the central and inner slats, is nevertheless removed from the ventilation grille. This is achieved by each central slat 9 having, on the V-point 16, a web 14 which projects inwards between two associated inner slats 11 and bears a channel 15 which is open towards the outside and extends parallel to the slats 7, 9, 11 transversely across the ventilation grille. The water which, in the air flow, passes through between the central slat and the adjacent outer slat, passes, guided by the web, into the inner channel which effects the carrying off of this water. <IMAGE>

Patent DE-3838097-A1 (DE)
Title: Chain assembly for chain conveyors
Inventor: TEKATHEN JOHANN
IPC: B65G19/20
Filed: 1988-11-10
Abstract: Chain assemblies for chain conveyors which are used in underground working and tunnelling for conveying bulk material comprise horizontal and vertical chain links which engage in one another, the vertical chain links being equipped with forged-on driving pins which project on both sides transversely and at right angles to the drawing direction. The vertically flattened vertical chain links are penetrated by the driving pins in the manner of a scrapper chain conveyor, so that optimum power transmission from the chain wheels to the chain assembly is ensured. In addition to the favourable force introduction, wear advantages result because the actual chain is almost kept free from wear by a corresponding design of the driving pins having wear caps and by the correspondingly attached driver arms. By this means, substantially longer service lives can be achieved, in particular as a result of the wear parts being connected to one another by convenient plug connection in such a manner that they can easily be separated from the actual chain assembly and replaced by new ones. <IMAGE>
