Title: Open=end spinning rotor with axial air exhaust port - forming part of yarn-withdrawal tube
Inventor: DERICHS JOSEF DR ING
IPC: D01H4/08
Filed: 1979-11-24
Abstract: The air-exhaust port in a rotor-type open-end spinning device is concentric with the rotor axis, and coincides with the mouth of the yarn withdrawal tube. An exhaust channel in the lid of the rotor housing connects the port with a chamber within the housing in which a suction conduit terminates. A bypass channel, closed by a flap valve which can be operated from outside the housing, short- circuits the interior end of the yarn withdrawal tube, to allow reverse-feeding of the starter-yarn to commence spinning. This construction permits a high-volume air-flow, even with small rotors, allowing the rotor speed to be increased and giving a faster prodn. rate of high-quality yarn with little fibre loss.

Title: Chemically sensitive measuring cells - based on insulated-gate FET as pH sensor
Inventor: KOSHIISHI KIYOZO
IPC: G01N27/414
Filed: 1980-05-27
Abstract: Measuring cells for determining the concn. of a given ion (I) in a test soln. comprise an ion-sensitive system electrochemically connected to the insulated gate of a pH sensor via a (I)-contg. liq. or gel or a conductive resin. The pH sensor is in the form of an insulated-gate field-effect transistor (IG FET). The potential difference (p.d.) between the test soln. and the ion-sensitive system is applied to the insulated gate of the pH sensor, whereby the concn. of (I) can be determined from the change in the source-drain current of the pH sensor. Measuring cells for determining the concn. of a given substance (II) in a test material comprise an O2 electrode and a chemically sensitive system electrochemically connected to an IG FET pH sensor via a conductive resin. The O2 electrode comprises Ag and Pt electrodes connected respectively to the positive and negative terminals of a direct-current source and generates a p.d. in response to the change O2 concn. in the chemically sensitive system. The p.d. is applied to the insulated gate of the pH sensor, whereby the concn. of (II) can be determined from the change in the source-drain current. Cells of type (A) can be used e.g. for Na+ or K+ determn. in blood serum. Cells of type (B) can be used e.g. for determn. of serum glucose, c.f. cells in which an ion-sensitive film is applied directly onto the insulated gate, the use of a conductive bridge between the insulated gate and the ion- or chemically sensitive system allows greater flexibility in the choice of systems, improves selectivity and durability, and reduces junction resistance and noise.

Title: Vehicle speech synthesis system equipment - mixes partial signal elements amplitude modulated at formant and noise frequencies
Inventor: TIMME MARTIN PROF DR ING
IPC: G10L25/00
Filed: 1980-07-24
Abstract: The speech synthesis system for use with compact equipment in a vehicle in which part signals corresponding to the speech level are added, uses a frequency which is a whole number times the basic speech frequency. A first set of part signals is used whose frequencies are near the formant frequency spectrum and each is amplitude modulated. Side lines are formed whose opposed frequency spacing is the same as the basic speech frequency. Three of the first three formants have a speech level corresponding to the first part signals, which are amplitude modulated according to a sawtooth function. The basic oscillation frequency of the sawtooth function is the same as the basic speech frequency. A second set of part signals having a frequency which approximates to the average frequency of a noise frequency are amplitude modulated with a noise signal. These modulated signals is mixed with an inverted signal of the same frequency and nearly the same amplitude.

Title: Call-metering system for telephone exchange - charges called member and not caller for held
Inventor: HILLIGES FRIEDRICH
IPC: H04M15/08
Filed: 1980-09-30
Abstract: The call-metering system has the calling subscriber releasing a request signal that causes metering pulses to pass to the tariff counter of the called subscriber instead of to the counter of the calling subscriber. Metering pulses are not sent to the calling subscriber. The number of the calling subscriber is converted at the called subscriber's end into a form suitable for calculating the rate for the call over the distance involved. The rate is used to control the passage of the metering pulses to the counter. The advantage lies in not charging callers for calls that are held at the called end (e.g. whilst the wanted personis sought).

Patent DE-3039693-A1 (DE)
Inventor: LARSSON GUNNAR
IPC: B21D53/04
Filed: 1980-10-21
Abstract: The invention relates to a method and an apparatus for the manufacture of heat exchanger elements. A pair of strips of weldable material e.g. high-grade steel is welded together in such a way that on both sides a longitudinally extending weld seam is formed, said pair of strips between said longitudinally extending weld seam defining a longitudinal channel which extends parallel to the weld seams and which serves for the conduction of heating or cooling agents. At least one of the strips is first provided with at least one longitudinally extending groove and is longitudinally welded to the other strip of the pair of strips in such a way that the groove forms with the part of the other strip covering it a longitudinal channel. A liquid filler material is poured into the longitudinal channel and solidified by cooling to below its freezing point. The pair of strips with the solidified or frozen filler material serving as a supporting core is subsequently shaped by plastic deformation of the walls without cutting in such a way that the longitudinal channel hereby acquires the desired shape and finally the frozen filler material is rethawed and removed from the deformed channel.

Title: Detecting reaching of predetermined level in container - using intermittently energised oscillation rod and measuring oscillation period until amplitude levels off
Inventor: KOMPA GUENTER DR
IPC: G01F23/00
Filed: 1980-11-25
Abstract: A vibratory rod, immersed into the container, has its free end at the preset level. The rod is energised into flexural oscillations by intermittent pulses from an excitation device. The oscillation period is measured w.r.t. the amplitude reaching a preset low threshold value in the interval between two excitation pulses. The attainment of the preset level is indicated when the measured oscillation period has dropped below a preset time period, smaller than the natural oscillation of the undamped rod. In the detector the swing rod is secured to a diaphragm. The connecting section is hollow, while the free end of the rod is solid. The centre axes of the diaphragm and rod are offset, and the diaphragm carries on the side away from the rod a piezoelectric transducer, receiving the excitation pulses. An evaluation circuit is connected to the transducer.

Title: Device for extending the tube of a Bowden pull
Inventor: BRAUER GERHARD
IPC: F16C1/22
Filed: 1981-01-19
Abstract: A description is given of a device for extending the tube of a Bowden pull. Seated in a fixed manner on the tube of the Bowden pull is an end fitting which, on the side facing away from the tube, has a spring tongue with a latching nose pointing towards the cable and having one oblique and one vertical flank. Pushed onto the cable is a guide bush inserted in a fixed manner, at the end facing away from the end fitting, in a holding device. In the region of the latching nose, the guide bush is provided with a corresponding toothing into which the latching nose resiliently engages. The oblique surfaces on the latching nose and the toothing are oriented such that it is only possible to pull the end fitting and the guide bush apart while their movement towards one another is blocked. Inserted between the end fitting and the guide bush is a compression spring which pushes the components apart automatically when the cable of the Bowden pull lengthens. Any such lengthening is thereby compensated automatically within the device by an automatic lengthening of the tube.

Abstract: The purpose of this support is to improve and to widen the possibilities for planting trees on roof surfaces upon which it is possible to walk and/or drive, e.g. in the case of parking decks, underground garages, sales buildings, production buildings, exhibition buildings, etc., without a considerable amount of useful space on the plane, located therebeneath, going to waste or special reinforcements of the floor structure being necessary, as has been the case hitherto. The invention comprises a concrete support which widens, in its upper part, to form a planting receptacle and serves as bearing means for the floor structure (see Figure 1). By fixing an overflow pipe, bottom outlet, water storage tank, hygromull and filter nonwoven, wetting and acidification of the vegetation substrate filling is prevented. In order to enlarge the root space, the support is supplemented by a planting frame. <IMAGE>
Patent DE-3104972-A1 (DE)
Inventor: ERNST ALFONS DIPL ING
IPC: G01D5/34
Filed: 1981-02-12
Abstract: An incremental measuring device is described which includes a measuring scale and a scanning unit. The measuring scale includes a division grid, a reference track which includes a plurality of reference marks, and a control track which includes a plurality of control regions. Each of the control regions is associated with a respective one of the reference marks, but the precise alignment between each reference mark and its respective control region is unique. The scanning unit includes a scanning plate which defines two separate scanning regions for scanning separate portions of the scale. Each scanning region defines reading fields for reading the division grid as well as a reference track reading field and a control track reading field. The precise alignment between the reference track reading field and the control track reading field of each of the scanning regions is different such that, for each of the scanning regions, there is only a single position of the scale with respect to the scanning plate which produces simultaneous alignment between the reference track reading field and one of the reference marks and the control track reading field and one of the control regions. In the disclosed embodiment photosensitive elements are associated with each of the reference track and control track reading fields, and each produces a respective signal. The four signals are summed in an analog manner to produce a composite signal which unambiguously indicates when the measuring scale is in a single, preselected position with respect to the scanning plate. In this embodiment, when one of two light sources included in the scanning unit fails such that scanning of one of the two scanning regions is interrupted, the device still functions to generate a reference signal unambiguously when the measuring scale reaches the predetermined position with respect to the scanning plate.

Title: Liquid filter, in particular for hydraulic media
Inventor: BERNHARD HERMANN
IPC: B01D35/153
Filed: 1981-03-10
Abstract: The invention relates to a liquid filter, in particular for hydraulic media. The liquid filter has orifices for the intake and efflux of the medium to be filtered, between which at least one filter insert is arranged. Above this filter insert is provided a degassing space having an outlet orifice, which degassing space is accessible from the impinged position of the filter insert. Gas filtered out from the medium to be filtered accumulates on the impinged side of the filter insert and can ascend as a result of the effective buoyancy forces in the medium, entering into the degassing space. In this it can flow to the outlet orifice to leave the degassing space. As a result, a concentration of filtered-out air is avoided on the impinged side of the filter insert and thus entrainment of air through the filter insert is avoided to any harmful degree. <IMAGE>

Title: Electrical continuous-flow heater
Inventor: HILLINGER ERICH
IPC: A47J31/54
Filed: 1981-03-30
Abstract: Electrical continuous-flow heaters are in widespread use in coffee machines or the like, to heat also the hotplate which is used to keep the ready-made coffee hot. The external dimensions of the hotplate correspond to the base of the coffee jug, that is to say it is essentially round, and the continuous-flow heater is also correspondingly shaped. In order now to make it possible to heat the coffee jug from a plurality of sides and, in addition, to simplify the construction of the heating system, it is proposed to design a continuous-flow heater (consisting of an extruded part which is provided with flow channels and a tubular heating element) such that the extruded part has a heating surface of broad dimensions which directly carries out the function of keeping the coffee hot and can be matched to the external shape of the coffee jug by corresponding subsequent forming of the continuous-flow heater.
