Title: Method and arrangement of a circulation test system
Inventor: NEUSEL ROLF
IPC: A61B5/308
Filed: 1981-02-24
Abstract: The subject-matter of the application permits recording, with comparatively little expenditure, of the medically vital circulatory parameters, e.g. blood pressure, pulse wave passage time, steepness of the pulse wave increase, and pulse rate per minute in each case allocated to the relevant cardiac action and synchronised by this cardiac action, and comparison of these parameters with synchronously recorded reference parameters specific to the subject. This eliminates the variation error which is very considerable due to biological variation when these values are not recorded at the same time, so that diagnostic evaluation of these circulatory parameters is much more precise than has been possible hitherto. In order to minimise the expenditure and to increase the accuracy, methods and arrangements according to the invention are presented in detail and special transducers are described. An interference-proof method is described for derivation of the synchronous signal of the cardiac action, and new methods are described for the determination of the passage time of a pulse wave and of blood volumes having different oxygen contents. In addition to the improvement in the measurement methods the subject-matter of the appliation minimises expenditure and simplifies application, and it can thus be used even in rural medical practices, it improves early diagnosis and the chances of a curative treatment, and it lowers the load on the public economy.

Title: Device for detecting the actual current value in half-controlled static converter bridge circuits with freewheeling branch
Inventor: ELGER HARALD ING GRAD
IPC: G01R19/22
Filed: 1981-02-25
Abstract: The invention relates to a device for detecting the actual current value at the alternating-current side in half-controlled static converter bridge circuits (2) with freewheeling branch. The load voltage (UB) of the alternating-current transformer (4) is used for charging a capacitor store (8) having a discharge time constant which is selected to be approximately equal to the time constant of the load circuit. The capacitor voltage is thus also proportional to the load current (IL) during the time in which the load current flows in the freewheeling branch. <IMAGE>
Patent DE-3107959-A1 (DE)
Title: Fluidised-bed apparatus
Inventor: NOWAK REINHARD
IPC: B01J8/38
Filed: 1981-03-02
Abstract: In a fluidised-bed container (10), an essentially horizontal, disc-shaped rotor (28) is arranged between an air chamber (24) situated below it and a working chamber (26) situated above it and can be rotationally driven about an at least approximately vertical axis. Arranged around the rotor (28) there is an annular closure member (42) whose height is adjustable, which in a lower position clears an annular gap (62), but in an upper position seals the annular gap (62), and, with its top side (52), forms a smooth transition between the top side (50) of the rotor (28) and an upper wall zone (54) of the fluidised-bed container (10). The rotational speed of the rotor (28) can be varied in accordance with the quality of the material to be treated and the type of the treatment process, almost at will and largely independent of the gap width, without incurring the risk of excessively forceful impingement of the material on the wall of the fluidised-bed container (10). The fluidised-bed apparatus can be employed for granulating, but equally readily for pelletising and/or encapsulating granulated material. <IMAGE>

Patent DE-3114401-A1 (DE)
Title: Calibrating devices for plastics profiles
Inventor: RIEDEL MANFRED ING GRAD
IPC: B29C48/90
Filed: 1981-04-09
Abstract: The invention relates to calibrating devices for plastics profiles. In the production of plastics profiles, calibrating devices undertake the final shaping of a desired profile. They may comprise rigid deflectors, plates, boxes or the like, past which a strand of plastic is passed to produce a plastics profile. As this happens, relatively great frictional forces occur between the strand of plastic and the calibrating devices shaping the profile, which has adverse effects on the plastic. The invention provides for calibrating devices which run along with the strand of plastic to be used, said devices being able to take the form of running belts, crawlers or the like and being designed according to a respectively desired plastics profile shape. Using this type of calibrating device, frictional resistances between the faces of the plastics profile and of the moving calibrating devices are reduced, as a result of which there is minimal stressing of the surface of the plastics profile and thus its physical properties are retained.
Patent DE-3118440-A1 (DE)
Title: Arrangement for classifying rod-like elements, in particular parquet pins
Inventor: HEINHAUS MATTHIAS ING GRAD
IPC: B07C5/14
Filed: 1981-05-09
Abstract: The invention relates to an arrangement for classifying rod-like elements, in particular parquet pins, having an advancing line for moving the elements transversely with respect to their longitudinal axis and with pneumatic actuating elements for sorting out individual elements according to predetermined specifications. The advancing line has one or more transversely directed lower outlet openings for the rod-like elements. Each outlet opening is assigned preferably two pneumatic actuating elements, specifically one on each side, each of which has a lower and an upper air outlet. The respective lower air outlet is aligned from below with a vertical component towards the outlet opening. Each of the two upper air outlets is preferably aligned from above essentially vertically towards the outlet opening. The two air outlets on each side of the outlet opening merely have to be set alternately to open. As a result a rod-like element can only drop down through the outlet opening when the respective lower air outlets are not fed with compressed air while the respective upper air outlets are fed and the element accelerates downwards. If, on the other hand, the two lower air outlets are fed with compressed air, the two upper air outlets are not fed so that it is not possible for a rod-like element to drop out of the outlet opening but instead it is conveyed onwards to the next outlet opening or to the end of the feed line. The arrangement also contains different embodiments of pneumatic actuating elements which can be used particularly favourably in conjunction with the arrangement. <IMAGE>
Patent DE-3127100-A1 (DE)
Title: Time delay switch
Inventor: SCHEMMEL HANS-ROBERT DIPL ING
IPC: H03K5/135
Filed: 1981-07-09
Abstract: Time delay switches are used in communications systems for delayed activation and de-activation of devices which perform a multiplicity of operations in a specific temporal sequence on the basis of the presence or absence of a pulse string. The time delay switch is intended to cause no activation or de-activation of a device which is controlled by the time delay switch for "noise signals" in a temporal interval shorter than an activation time constant or de-activation time constant. For this purpose, the time delay switch (1) contains a pulse generator (2) whose pulse (P) is independent of the pulse string (S). This pulse (P) and the pulse string (S) are in each case connected to the clock input (T1, T2) of a first and second counter (3, 4). The counters (3, 4) can be reset with the aid of a control circuit (5, 6, 7), a switch latch (8) being connected to the control circuit (5, 6, 7) and emitting corresponding activation/de-activation control commands for the device. <IMAGE>

Title: Device with a gearbox
Inventor: FICKELSCHER KURT ING GRAD
IPC: F16H1/28
Filed: 1981-12-28
Abstract: The invention relates to a device with a gearbox which is connected to a shaft journal, it being possible to feed lubricant to the bearings of the gearbox and/or the shaft journal by means of a pump. In a device of this kind, there are special requirements as regards an adequate supply of lubricant and, in the case where the lubricant pump and the necessary pipes are arranged externally, the requirements of reducing the risk of fire and proofing against earthquakes previously demanded a high outlay. The known devices of the said type also have a comparatively great overall height. To obviate these difficulties, the invention proposes to arrange on the shaft journal a locating body to which is assigned a bearing support of a housing, and to arrange the rotor of the pump for supplying at least one bearing with lubricant on the shaft journal. <IMAGE>

Title: Rivet-type attachment of haberdashery articles, such as press stud closures
Inventor: NYSTEN BERNHARD DIPL ING
IPC: A44B1/44
Filed: 1982-03-29
Abstract: In a rivet-type attachment of haberdashery articles, on the one hand an attachment member having a projecting, deformable holding shank and, on the other hand, a functional member, such as half a press stud closure, with a blind bore for receiving said holding shank are used. The holding shank exceeds the depth of the blind bore and is deformed therein when the attachment member and the functional member are pressed axially against one another. For the purpose of a smooth connection, it is proposed that the attachment member be constructed from two axial portions which are opposite in shape, namely an offset male part on the shank end and a female part with an axial hollow space in the adjoining shank portion. The hollow space is aligned axially with the male part and has a tapered clear width compared to the cross section of the male part. When pressed against one another, the male part is pushed axially by the bottom of the blind bore of the functional member into the hollow space of the adjoining female part and the wall region surrounding the hollow space of the female part is expanded radially and fixed in the blind bore.
