Filed: 1986-10-27
Abstract: A hot profile-steel workpiece having a flange width dimension, a web height dimension, and a web thickness dimension is rolled in a roll train including a reversible univerial rolling stand and a flange-compacting roll stand unstream therefrom. According to the invention one of the height, width, or thickness dimensions of the incoming workpiece is reduced upstream of the flange-engaging compacting roll stand. Normally the web height dimension is reduced in a roll stand immediately upstream of the universal and flange-compacting stands. Furthermore the workpiece has a web with extra-thick parts and these extra-thick parts are rolled out by horizontal rolls of a roll stand that engage this web. The flange-compacting roll stand engages the faces of the flanges. With this system it is possible to make the web of the incoming workpiece either shorter or taller, that is it can either be compacted or rolled out.

Title: Small (miniature) electric motor
Inventor: DEISS ROLF-DIETER
IPC: H02K5/14
Filed: 1986-12-23
Abstract: Small electric motors are already known which have a motor housing for the motor armature, a bearing plate which closes the motor housing at the end and on which a holder for a bearing of the armature shaft is constructed, and a brush holder plate which is mounted on the bearing plate and rests by means of its outer edge on an inner shoulder of the bearing plate and against a surface, which is coaxial with respect to the axis, of a collar of the bearing plate. A relatively large amount of space is in this case occupied by the inner shoulder, which space is lost for the accommodation of electrical components on the brush holder plate. In order to make more space available while maintaining a coaxial alignment of the brush holder plate, a small electric motor according to the invention is constructed such that the inner shoulder has sections of different width, and such that the brush holder plate rests against the coaxial surface of the collar on all sections.

Title: Method for cutting correct weights of products of a solid consistency
IPC: G01G19/52
Filed: 1987-04-29
Abstract: The domain of the invention is the fully automatic cutting of correct weights of products of a solid consistency and variable cross-section (for example foodstuffs such as sausage, cheese, meat, fish, etc.). To date, the weight of slices which have already been cut off has been determined and an attempt has been made to determine the necessary thickness of the next slice to be cut on the basis of this. The high degree of inaccuracy and the slow processing speed are disadvantageous. In the case of the invention, the product is made to stand out so clearly against its background by the use of additional radiation sources that the relevant cutting surface can be unequivocally detected by sensors. As the desired weight and the specific weight are known, the cutting depth can be simply determined by means of an electronic evaluation unit. An electronic control unit generates an electrical signal which triggers a positioning device. When the correct cutting depth has been set, a cutting device cuts a slice of the desired weight off the product. Figure 1 shows the mechanical layout of the light source 7, the cutting knife 1, the camera 4 and the product 8. <IMAGE>

Title: Apparatus for the treatment of blood by dialysis and/or filtration
Inventor: SCHAEL WILFRIED DR ING
IPC: A61M1/36
Filed: 1987-06-23
Abstract: The apparatus for the treatment of blood by dialysis and/or filtration has an extracorporeal blood circulation with monitoring units. Chambers (9, 35) are provided to monitor the pressures upstream and/or downstream of the dialyser or filter arrangement (5) and are preferably designed so that the internal pressure is directly transmitted by the elastic chamber wall without pressure diversion tubes to pressure sensors (10, 16). The chambers simultaneously serve as air traps, and the output signals are evaluated upstream at sensors (11, 37) arranged on the supply lines so that single air bubbles passing the location of the sensor trigger a warning signal and, in order to measure the collected amount of air, times during which air passes the sensor in place of blood are summed in order to stop the circulation when a particular air volume which is smaller than the chamber volume is reached. The sensors (11, 37) located upstream of the chambers, or additional sensors (12, 92) located downstream, can be designed in conjunction with an extended evaluation circuit (Fig. 2) so that a measurement of the blood flow takes place at the same time as the measurement of air. A variable characterizing the flow conditions in the dialyser or filter arrangement and the viscosity of the blood is derived from the signals from the pressure sensors (10, 36) and the blood flow and is monitored. <IMAGE>

Title: Controllable sealing system for catheter and instrument insertion kits
Inventor: STAEBLEIN ALEXANDER
IPC: A61B19/00
Filed: 1987-11-02
Abstract: Medical interventions in hollow organs have to date frequently been carried out with thin-walled plastic tubes inserted in the hollow organ. If there is a pressure difference between the outside and the hollow organ, problems arise that have previously been solved by using elastic abradant seals which damaged sensitive instruments or tissue parts to be removed, however. In the present case, the seal used is an annular sealing cuff of an elastic or at least flexible material which seals, narrows or exposes the cross-section to be sealed on filling of the cuff interior with gaseous or liquid media. A pneumatically or hydraulically controllable sealing cuff permits partial or complete closure of the cross-section of the connection between the hollow organ and the outside as required, or complete exposure of it, and this permits unproblematical insertion even of sensitive instruments especially in conjunction with a conventional sealing system in the form of the specified system.

Title: Method for autofocusing of microscopes, and microscopes with an autofocusing system
Inventor: BIERLEUTGEB FRITZ
IPC: G02B21/24
Filed: 1987-11-19
Abstract: In a microscope having a continuously or discontinuously variable objective magnification an autofocusing system is provided whose beam path traverses the objective, is guided out of the path of the image rays between the objective and the eye-piece, and leads to at least one photo-electric detector device. At least one optical system is incorporated or can be incorporated in the beam path of the autofocusing system, which in the event of a change in the objective magnification makes possible or causes a scale alteration (change) of the at least one image produced on the detector device. The at least one optical system can be a variable power system (zoom system) or a number of lenses or fixed lens systems which can be brought into the beam path of the focusing system. A coupling mechanism causes, in the case of a change of the objective or a change in the objective magnification, the focal length of the at least one optical system which is brought or which can be brought into the beam path of the autofocusing system to be varied correspondingly. A pattern containing a light-dark contrast is furthermore projected into the object plane, which pattern, when incident light technique is used, ensures reliable locating of the optimum focus adjustment even in the case of low object contrasts.

Title: Hydrostatic-mechanical power-shift transmission with a continuous effect
Inventor: JARCHOW FRIEDRICH PROF DR ING
IPC: E02F9/20
Filed: 1988-05-09
Abstract: The transmission consists of a multi-shaft planetary gear mechanism, a continuously variable hydrostatic transmission, rear-mounted gear stages and clutches. The hydrostatic transmission includes a positive displacement machine with a variable displacement volume and a positive displacement machine with a constant displacement volume. In the planetary gear mechanism, one shaft forms the input shaft and the variable positive displacement machine is connected to this. A second shaft of the planetary gear mechanism is connected to the constant-volume positive displacement machine. A third and fourth shaft of the planetary gear mechanism represent coupling shafts. In an extreme position of the hydrostatic transmission, these rotate at the same speed and, when the hydrostatic transmission is adjusted to the other extreme position, there is a continuous increase in the speed of rotation of one of the coupling shafts and a continuous decrease in the speed of rotation of the other, and these coupling shafts act alternately, in each case via at least two rear-mounted stages, also known as gears, on the output shaft. In the extreme positions of the hydrostatic transmission, gear changes are performed at synchronous speeds, in a load-free manner and without interruption to the tractive effort, by selector clutches. Control and regulation of the automatic transmission is performed by electronic and hydraulic means.

Abstract: In order to obtain an optimum welding speed in a method of joining workpieces, in particular sheet metal, by means of laser radiation, even in the case of thin sheet metal, the procedure is to control the intensity of the laser radiation for forming a laser-induced plasma at the joining point as a function of one or more joining-point parameters, and to increase the intensity of the laser radiation until the threshold intensity, or a slightly higher value, required for forming the plasma is reached, and then, after maintaining the set intensity for a predetermined time, to lower the intensity to a value extinguishing the plasma.
Patent DE-3823014-A1 (DE)
Title: Slubbing-blocking device
Inventor: SPROED PETER
IPC: D01H13/18
Filed: 1988-07-07
Abstract: Known slubbing-blocking devices restrict the servicing region of the drawframe to a greater or lesser extent, especially since the often high outlay in terms of construction takes up a corresponding servicing space in terms of textile technology. The free space in the region of the drawframe is also restricted in respect of the air-conditioning and the cleaning outlay. With the new slubbing-blocking device, the possibility for servicing and maintenance in the region of the drawframe is to be scarcely impaired. The slubbing-blocking device consists of a stationary lower part (4) with a clamping device (5) and a receptacle (6) for the electrical constructional unit and of a pivotably mounted extendable two-part slide (8) longitudinally guided on the lower part (4) and connected releasibly to the blocking member (14), a tension spring (10) with an effective line constantly extending obliquely relative to the longitudinal movement of the slide (8) is arranged between the lower part (4) and the slide (8), and the longitudinally movable pivotable slide (8) is guided with its shaft (13) in a longitudinal groove (12) of the lower part (4), the longitudinal groove (12) corresponding to the working stroke of the slide (8). The slubbing-blocking device for drawframes on spinning machines is arranged on the same holding rod as the upper-roller supporting arm, it can be mounted from above and, in the event of a thread break, it interrupts the condenser delivery by means of a blocking member guided under the condenser slubbing and the upper roller of the pair of feed rollers. <IMAGE>

Title: Method and apparatus for loading and transporting refuse or the like
Inventor: ROCHOLL JUERGEN
IPC: B65F3/28
Filed: 1988-07-27
Abstract: The invention relates to a method for the disposal of refuse or the like, especially for the loading and transporting of the refuse between a collection station and a refuse dump, wherein the collected refuse is introduced through an aperture in an end face of a container, with compression, and after closure of the introduction aperture is driven to the dump in the container and deposited there, and its object is to achieve optimum filling of the containers without wasted space within the container and a substantial reduction of the ejection forces to be applied. To this end, according to the invention, it is proposed that the depositing of the refuse take place by ejection from the container through a closable ejection aperture located at the end face of the container opposite to the filling aperture, the orientation of the refuse in the container, which is predetermined by the insertion by the press at the collection station, being retained and the ejection onto the dump being favoured (Fig. 3). <IMAGE>
