Title: Method and arrangement for suppressing oscillations
Inventor: WAGNER GERHARD DR ING
IPC: B66C13/06
Filed: 1987-03-30
Abstract: The invention concerns a method for suppressing oscillations while transporting a load suspended by several ropes from a crane trolley at the destination, with the ropes being of the same length and attached to points of the load some distance apart. In order to create such a method and an arrangement making it possible to suppress totally the oscillations of the load suspended by several ropes, in particular during automatic transportation of loads, so that very precise positioning of the load is possible at an optimum speed, it is proposed that   a) the braking of the trolley's motion ahead of the destination corresponds exactly to a negative acceleration time characteristic during the starting operation and b) the trolley's speed of travel between the end of acceleration and the beginning of deceleration be controlled so that, at the halfway point between the origin and destination, a zero crossing of the load's oscillatory motion occurs.   <IMAGE>

Title: Ruler, especially parallel ruler with vertically adjustable carriage
Inventor: KELLERMANN BERNHARD CLEMENS
IPC: B43L13/04
Filed: 1987-08-21
Abstract: The invention relates to a carriage for a parallel ruler with a parallel control system, which has a cord which extends over four points and intersects itself diagonally in the central region of the ruler. The ruler according to the invention consists of three parts: a ruler body, a gripping and reinforcing strip, and a carriage. The carriage is fixed on the ruler bar by a screw connection so as to be vertically and laterally displaceable, and capable of rotation, and accepts the cable guide rollers and the running wheels in a metal construction. The drawing rail is particularly easy-running as a result of this type of carriage and always remains 100% parallel in any position because of its rotatability and lateral displaceability. Furthermore, the carriage can be set to any desired arrow height, catching on the drawing being avoided. As a result of the variable length and the adjustable distance from the drawing substrate, a drawing rail according to the invention becomes the ideal instrument for graphical work (architectural drawings, etc.). <IMAGE>

Patent DE-3741386-A1 (DE)
Inventor: DEL SANDERS MYRON
IPC: E05F1/12
Filed: 1987-12-07
Abstract: A hinge incorporating an elastomeric spring intended primarily for the doors of vehicles, has an outwardly projecting detent 48, 49 formed on a first bracket 2 mounted on the vehicle frame 3 and a roller 37 formed of a compressible elastomeric material mounted on a second bracket 17 attached to the vehicle door, the brackets being pivoted together at axis 13. The detent is in the path of movement followed by the roller upon movement of the door toward the closed position. The roller retains the door in the open position requiring temporary compression of the roller to move the door toward the closed position. The detent may have two projections which provide an intermediate door position or have an elongated ramp configuration to achieve other door opening and closing characteristics. Another detent may be formed on the first bracket to partially compress the roller when the door is in the closed position to bias the door toward the open position. The elastomeric roller completely eliminates metal spring components heretofore used in prior hinge spring devices. <IMAGE>

Title: Clutch for hand-held electric tools
Inventor: OCHS HUBERT DIPL ING
IPC: B27B5/38
Filed: 1987-12-12
Abstract: The functioning of known clutches used in hand-held electric tools is restricted to the actual engaging operation. After disengagement of the drive, the tool thus remains in motion for a while, unless additional measures to stop the tool are taken. The new clutch is intended to ensure a rapid stopping of the tool after the drive motor has been switched off. To achieve the desired aim, one part of the wrap spring (4) encloses the circumferential surface of the drive shaft (1) and the other part of the wrap spring encloses the circumferential surface of the output shaft (3). The wrap spring, whose output-side end (7) is positioned by means of a switching ring (9), is assigned a braking sleeve (12) which is fixedly connected to the output shaft (3) and concentrically encloses the wrap-spring part situated on the output shaft (Fig. 1). <IMAGE>

Title: Valve with a presetting of the throughflow quantity
Inventor: LETZEL HELMUT
IPC: F16K31/68
Filed: 1987-12-23
Abstract: In a thermostatic valve for hot-water heating systems with a presetting of the throughflow quantity, there are provided a spring-loaded valve body 8 capable of being lifted off the valve seat and a presetting body 4 which surrounds the valve body in a sleeve-like manner and can be arranged independently of the latter in the axial direction and the outer surface of which, together with the seat element 26 forms the limitation of the preset throughflow cross-section. At the same time, the presetting body 4 can be arranged with a setting sleeve 5 surrounding and driving the latter. In this construction, after the presetting has been carried out, the relative arrangement of the presetting body 4 in relation to the corresponding valve seat, forming the throttle cross-section, on the valve element is not varied, since, during assembly, the presetting body, together with the setting sleeve arranged according to the latter, is always positioned in a uniform manner, that is to say always in the same axial arrangement in the valve housing 1. <IMAGE>

Patent DE-3810609-A1 (DE)
Inventor: BUEHLER GERHARD
IPC: B01F7/16
Filed: 1988-03-29
Abstract: An apparatus for mixing and homogenising fluid products comprises a vacuum vessel (1) which can be closed by a cover (3), a homogenising device (16, 17) arranged underneath the former and a mixing or stirring device (18-23) fitted to the cover. The homogenising device (16) is arranged at a vertical suction distance above the vessel bottom (13) and, in the lower part of the vacuum vessel (1), a rotatable hollow guide cone (34) is provided which widens upwards to an annular flow gap towards the vessel wall (36). The material extracted laterally from the vessel bottom (13) is conveyed into the upward-widened guide cone (34) and along the conical inner surface upwards/outwards to the upper edge (38) and along the annular flow gap thereof to the vessel wall (36). The material thus largely spreads uniformly with steady thinning of the layer and flows in a thin annular stream (from) the upper edge (38) of the cone to the vessel bottom (13) and is again conveyed upwards by the homogenising device (16). The large shear forces in the region of the upper edge (38) of the guide cone (34) here contribute to more extensive comminution and homogenisation of the material. <IMAGE>

Title: Nuclear magnetic tomography method for the determination of the spatial distribution of nuclear magnetisation in a layer and arrangement for carrying out the method
Inventor: KUHN MICHAEL HARALD DR
IPC: G01R33/54
Filed: 1988-04-16
Abstract: The invention relates to a nuclear magnetic tomography method for the determination of the spatial distribution of nuclear magnetisation in a layer of an examination region perpendicular to a first direction, a number of sequences working on an examination region in the presence of a homogeneous stationary magnetic field, each sequence comprising at least two layer-selective radio-frequency pulses, a magnetic field having a gradient running in a second direction perpendicular to the first direction being switched on apart from the radio-frequency pulses, the size and/or switch-on period of the gradients being changed from sequence to sequence and an echo signal being received and scanned following the radio-frequency pulses in the presence of a magnetic field having a gradient running in a third direction perpendicular to the first two directions, from which echo signal the distribution of the nuclear magnetisation is reconstructed; and an arrangement for carrying out this method. To reduce the measuring time and to improve the spatial resolution capability it is proposed in this case that, during one of the radio-frequency pulses, a magnetic field having a gradient running in the second direction is switched on, and that the bandwidth of one radio-frequency pulse and/or the amount of the gradient of the consequent associated magnetic field is adjustable, so that by this means, the nuclear magnetisation in an adjustable part of the...

Title: Spectacle lens edge-grinding machine
IPC: B24B47/22
Filed: 1988-04-28
Abstract: The invention relates to a spectacle lens edge grinding machine having at least one rough-grinding wheel and having a plurality of facet-grinding wheels which are arranged at an axial distance from a grinding-wheel shaft. Provided approximately parallel thereto is a lens-holding shaft for receiving a spectacle lens to be ground. In addition, a device for adjusting the distance between the shafts, and an adjusting device with which the position of the two shafts relative to one another in their axial direction can be adjusted, are provided. Furthermore, a transducer which, with its sensor in the measuring position, records the position of the lens edge of a spectacle lens, which is held in the lens-holding shaft and is to be ground, after the rough-grinding relative to a first facet-grinding wheel is provided, through the signal of which transducer the axial displacement of the lens-holding shaft or grinding-wheel shaft is switched off when the spectacle lens to be ground has reached the desired position in front of said facet-grinding wheel. When another of the facet-grinding wheels contained in the spectacle lens edge-grinding machine is to be used for the spectacle lens, the position, found by means of the transducer, of the spectacle lens to be ground relative to the first facet-grinding wheel forms the starting position for a subsequent positioning of the spectacle lens to be ground with respect to the further facet-grinding wheel. The subsequent positioning may be carried out path-dependently or time-dependently.

Title: Clamping piece for probes
Inventor: KNAEBEL HORST DIPL ING
IPC: G01B5/00
Filed: 1988-10-10
Abstract: Conventional clamping pieces for mounting and positioning electric probes on baseplates of measuring machines are mostly specially designed for a specific type of probe and are large, because in their case probes, prods and setting and resetting members are arranged offset. In the event of rough operation, when the test object brings with it dirt, water, lubricating oils and cutting oils (fluids) and the like, they do not guarantee reliable measurement operation. In order to prevent these disadvantages, the invention proposes a standardisable clamping piece (10) for probes (18), which consists of a basic body (12) having a central through bore (16) for accepting a probe (18) and an auxiliary piston (20). A web (34), which in conjunction with a clamping bolt (38) serves to clamp the probe (18), is cut free in the basic body (12) by three slotted grooves. The central through bore (16) in the basic body (12) is sealed towards the test object, for example by an elastic diaphragm (48) which is mounted in the basic body (12) and on the auxiliary piston (20). If necessary, the clamping piece (10) can be provided with a compressed air connection for resetting the probe (18) and for the supply of purging air. <IMAGE>

Title: Tachometer
Inventor: HUBER NORBERT
IPC: G01P3/44
Filed: 1988-10-11
Abstract: In this tachometer, two periodic, mutually phase-shifted measuring signals (M1, M2) of an incremental rotary position transducer (D) in a frequency stage (F) for frequency multiplication are respectively fed to an analogue-to-digital converter (W1, W2) downstream of which a programmable memory (PS) is connected. The frequency stage (F) forms from the two periodic measuring signals (M1, M2) two high-frequency periodic rectangular-pulse signals (U1, U2) with the same phase shift, from which a direction discriminator (RD) generates by means of multiple evaluation four output signals (S1-S4) which are respectively fed to a switching stage (SS1-SS4) for pulses of constant energy. The output signals (T1-T4) of the four switching stages (SS1-SS4) are fed via a summation amplifier (SV) and via an integration stage (TF) to one input of an amplifier (V) at whose output a tachometer signal (TS) is present which is proportional to the frequency of the rotary position transducer (D). A directional signal (RS) of the direction discriminator (RD) for the sense of rotation of the rotary position transducer (D) is applied to the other input of the amplifier (V) in order to switch the sign of the gain. <IMAGE>

Title: Frequency divider for microwave range
Inventor: BARTH HELMUT DR
IPC: H03B19/18
Filed: 1988-12-01
Abstract: The invention relates to a frequency divider for microwave range, particularly the millimetre wave range, in which a Gunn oscillator operating as harmonics oscillator is used which is synchronised to the nth haromonic oscillation of the frequency fn = n.f1 with n >/= 2 and outputs the first harmonic oscillation f1 as output signal with power gain. A greater operational band width is achieved with frequencies fn for which (n-d) ft < fn < n.ft holds true, ft being the domain transit time frequency and d being the domain delay of the Gunn oscillator. This condition is achieved, on the one hand, in the so-called harmonically triggered operation of the Gunn oscillator in which the bias voltage UO of the oscillator is greater than its domain holding voltage UH and slightly less than its threshold voltage US and, on the other hand, in the so-called harmonic domain delay operation in which the bias UO of the Gunn oscillator is greater than its threshold voltage US.
