Patent DE-3045448-A1 (DE)
Title: Electromechanical level measurement - using contactless switching arrangement on cable moved vertically by electric stepper motor
Inventor: HUESTER BERNHARD ING GRAD
IPC: G01F23/44
Filed: 1980-12-02
Abstract: The electromechanical level measurement device measures instantaneous level and level changes without contact or the application of force. The switching device is carried on a flat cable which is moved up and down by an electric motor. When it reaches the surface the switch sends a pulse to the motor causing the cable to be rewound. A measurement wheel joined to the motor measures the level. A stepper motor is used which feeds the switching device stepwise via the measurement wheel to a float limited in movement by a guidecage. Contactless switching elements produce motor switching steps when the level changes. They are mounted on the end of the cable with a wt. and the cage.

Title: Automatic metering-monitoring device for an electromechanical balance
Inventor: FELDHANS GERHARD ING GRAD
IPC: G01G13/30
Filed: 1981-01-10
Abstract: The automatic metering-monitoring device for an electromechanical balance with coarse-stream and fine-stream feed has a metering slide (5) for the coarse stream, a metering-time controller, a first change-over switch for different filling weights and a second change-over switch for the residual emptying. The filling material is fed from a supply container (1) to an inflow funnel (2) equipped, above the metering slide (5), with a level sensor (4) which, when the filling quantity in the inflow funnel (2) corresponding to the height of the level sensor falls below the desired value, transmits a signal to an evaluation unit of the control. The metering slide (5) is shown in this basic position in the drawing and can be moved continuously into different operating positions by means of a drive (6). A weighing container (11) is arranged underneath the outflow orifice (7) to which flaps (8 and 9) are assigned. When the filling quantity in the inflow funnel falls below the level sensor (4), the metering slide and the metering-time controller are moved into their previously determined basic-position values via a signal transmitted to an evaluation unit of the control. These basic-position values are also assumed when the first change-over switch is actuated in order to set another filling weight. When a residual emptying is initiated by means of a second change-over switch, the memory of the automatic afterflow controller is erased. <IMAGE>

Title: Digital frequency/phase comparator
Inventor: BURGER ERICH ING GRAD
IPC: H03K5/26
Filed: 1981-07-30
Abstract: The present invention relates to a digital frequency/phase comparator (KP) comprising the series-connection of a frequency-sensitive section (FT) and a phase-sensitive section (PT), in which the frequency-sensitive section (FT) exhibits a first input for the pulse sequence (f1), the repetition rate of which is to be controlled, and a second input for a reference pulse sequence (f2). It is proposed that the frequency-sensitive section (FT) exhibits at its two inputs in each case one D-type flip flop (K1, K2) which can be reset via a common gate (G). In addition, the phase-sensitive section (PT) receives at its first input the output signal (A) of the D-type flip flop (K1) receiving the pulse sequence (f1) to be controlled. The second input of the phase-sensitive section (PT) is directly supplied with the reference pulse sequence (f2). The phase-sensitive section (PT) samples the one input signal (A or, respectively, f2) with the positive or negative edge of the other input signal (f2 or, respectively, A) depending on definition, and the sampled value (B) is present until a new sample is present. Such digital frequency/phase comparators are used in highly stable phase-locked loops, for example for a data multiplexor in radio-relay equipment in modern radio engineering. <IMAGE>

Patent DE-3134584-A1 (DE)
Title: Resistive material, electrical resistor, and method for manufacturing it
Inventor: WAHLERS RICHARD LEE
IPC: H01C17/065
Filed: 1981-09-01
Abstract: The invention relates to a resistive material, in particular a glassy resistive coating material which, to form an electrical resistor (10), is applied to a substrate (12) and is fired thereon, to an electrical resistor and to a method for manufacturing it. The glassy resistive coating material consists of a mixture of a glass frit, an insulating material containing a zirconium oxide, and fine particles of tin oxide (SnO2), optionally with tantalum oxide (Ta2O5) as the conductive phase. The insulating material is preferably selected from the group comprising zirconium oxide (ZrO2), calcium zirconate (CaZrO3), barium zirconate (BaZrO3) and strontium zirconate (SrZrO3). Owing to the proportion of the insulating material consisting of a zirconium oxide, the glassy coating material results in electrical resistors which can be set to a high resistivity, have stable or fixed physical properties and are relatively insensitive to the firing temperature being increased. <IMAGE>
Patent DE-3136440-A1 (DE)
Title: Clamping device for clamping tools
IPC: B21D5/02
Filed: 1981-09-14
Abstract: The clamping device is used to clamp tools relative to part of a machine and has a clamping part which can be moved together with a pressing part towards the tool. The clamping part is provided with a securing part which can be moved out of a release position into a holding position. On release of the clamping device, the tool is thereby secured against falling out by the securing part, which is in the holding position. As a result, no latching noses or the like are necessary on the tool and it can thus have flat outer surfaces. As a result, it can be pushed from below into the socket between the clamping device and the part of the machine or withdrawn from it. No free space is therefore required next to the machine and adjacent tools can be exchanged independently of one another in a simple manner.

Patent DE-3139286-A1 (DE)
Title: Pressure pick-up for melts, abrasive media and solid beds
Inventor: LUTTERBECK JOACHIM DR ING
IPC: G01L7/08
Filed: 1981-10-02
Abstract: The invention relates to a pressure pick-up for melts, abrasive media and solid beds, in particular for use in plastics-processing machines. The pressure measurement is performed by a metal plate, the thickness of which is designed for the pressure range to be measured. The deformation of the metal plate causes a volume displacement to take place behind it, which is transmitted by a liquid to the measuring element. Since the metal plate takes the forces of the pressure, the liquid pressure is relatively low. Temperature influences which are caused by thermal expansions are compensated by the liquid and the surrounding housing thermally expanding in the same way. This is achieved by a liquid-solid mixture. Due to the stable form of the metal plate, the pressure pick-up can be used both in hot polymer melts and in abrasive media and solid beds, such as plastics powders and granules.

Title: Process and apparatus for the forming of thermoplastic film
Inventor: SCHMIDT WERNER
IPC: B29C51/08
Filed: 1982-02-02
Abstract: For the forming of thermoplastic film, the latter is heated by ultrasonic action. This is accomplished by subjecting the film to a sharp deflection when in contact with an ultrasonic tool. This can be performed by upsetting on a surface of the tool or by drawing the film over an edge of the tool. In the case of a stretched-out film surface, this can be achieved by movement of a forming die at a small angle against the film surface. The process is suitable in particular for deforming foam thermoplastic film, for example to form a peripheral stacking edge in the conical body of a cup container.

Patent DE-3235117-A1 (DE)
Title: Hose or cable entry
Inventor: BOMMER HEINZ
IPC: H02G15/013
Filed: 1982-09-22
Abstract: In the hose or cable entry according to the invention, a cap (5) having a central hole (6'), aligned with the entry opening (6), is screwed onto a connecting piece (3) provided with an external thread (4). Capsules (9) which are filled with adhesive (10) and can be destroyed by pressure are arranged between the inner wall (7) of the cap (5) and the end face (8) of the connecting piece (3). When the cap (5) is screwed tight, the capsules (9) burst, the adhesive flowing out bonds the cable or hose sleeve located in the entry opening (6) to the parts of the entry surrounding it, and at the same time forms a seal. Once the adhesive has set to form an elastic compound having shear strength, the inserted cable is relieved of tension in a simple manner, without radially directed pressure being exerted thereon. A preferred application of the invention is for entries of optical fibre cables of apparatus housings or cable sleeves. <IMAGE>
