Title: Roller-blind device
Inventor: HOENLE HERBERT
IPC: E06B9/17
Filed: 1981-01-31
Abstract: In order to improve operating safety with the least possible outlay and to reduce the assembly outlay, at least two roller catches (31) are screwed onto the upper transverse leg (22) of the window frame. The rollers (38) point upwards and the top-side surface region of the body between the roller (38) and the screw-on surface is at a distance from the underside of the window lintel (29) which corresponds to the dimension between the top side of the upper wall and the underside of the longitudinal profile. The box profile of the guide rail possesses, in the region located opposite the locating pin, a recess which makes it possible to push the locating pin into the box profile. The recess is preferably provided in the outer region of the box profile. The device allows much larger roller-blind lengths than has hitherto been possible. <IMAGE>

Title: Method and arrangement for measuring the displacement angle between two phase-shifted signals
Inventor: NOVOTNY JAROSLAV
IPC: G01R25/00
Filed: 1981-02-27
Abstract: To determine the phase angle between two periodic signal voltages, for example for setting the phase angle in static converter systems, electron beam oscilloscopes are equipped with adaptors which provide for a displacment of the phase angle of at least one of the measurement voltages, the scale of which displacement can be detected. Using the adaptor according to the invention, in contrast, bright-up spots (A, B, C), which can be set to the points of intersection of the imaged measurement voltages (I, II) with the X axis, are derived from the deflection voltage (1) for the X axis of the oscilloscope. The time (t) between two bright-up spots of successive points of intersection of the measurement voltages and the duration (T) of the period also marked by two bright-up spots is measured and from this the phase angle is calculated. The calculated value is supplied to a digital display (7). <IMAGE>

Title: Cap for an aerosol can for cleaning drainage pipes
Inventor: DRESCHNER HORST
IPC: E03C1/30
Filed: 1981-03-26
Abstract: It is often the case that aerosol cans (10) for cleaning drainage pipes can only be placed, by their caps (11), in an offset manner on the drainage holes of basin-type drainers (13) or sinks if said drainage holes are arranged such that they adjoin a side wall (14) of the basin (33) directly. This gives rise to poor pressure transfer into a drainage pipe (17). An improved pressure transfer is possible when using a cap attachment (12) which is placed onto the cap (11), for example, by means of an adhesive-coated base surface (26) and has a cylindrical main part (27) of essentially circular cross-section with a smaller diameter than that of the guide cylinder (21) of the cap (11). Such aerosol cans (10) with cap attachment (12) are used, in particular, in catering concerns, since the bar units which are conventionally used there are designed such that their drainage holes are located directly next to a side wall (14) of basin-shaped drainers (13). The aerosols are also used wherever blockages of a drainage pipe (17) occur particularly frequently. <IMAGE>
Patent DE-3115406-A1 (DE)
Title: Arrangement for increasing the output current of amplifiers
Inventor: SIEGEL HORST DIPL ING
IPC: H03G1/00
Filed: 1981-04-16
Abstract: An arrangement is proposed for increasing the output current of pre-amplifiers (2), which is used in particular to provide digital levels in data lines which can receive both transmit and receive signals. The circuit arrangement has a switch (5) with which the output stage transistors are switched to floating in receive mode. A further switch (4) is used to suppress noise pulses from the output of the pre-amplifier when the output stage is de-activated. Current-limiting resistors (8, 9) limit the maximum current of the output stage. Diodes (11, 12), which prevent an impermissible rise in the emitter voltage, are connected in parallel with the collector-emitter path of the transistors (6, 7) and the current-limiting resistors (8, 9). A resistor (10) limits the maximum current flow through the diodes (11, 12). A reverse feedback arm with a resistor (13) compensates for the voltage drop on the resistor (10) in transmit mode. <IMAGE>

Title: Electromagnetic actuating device for an actuating element
Inventor: HEISER JOACHIM DIPL ING
IPC: H01F7/13
Filed: 1981-04-24
Abstract: An electromagnetic actuating device (10) for a position-controlled actuating element (16) is proposed which, as a servo valve spool of a hydraulic directional control valve (15), enables the speed of a hydraulic load to be controlled. The spring-centred servo valve spool (16) is operated by two magnets (22, 25) which can be connected to the regulator (13) via a changeover device (12) which is controlled in a directionally dependent manner, such that the magnet (22, 25) which deflects the servo valve spool (16) receives the control variable (Y) from the regulator (13), while the other magnet (25, 22) is connected to a measurement device (14) in order to detect the actual position value of the servo valve spool (16). The armature (23) which is in each case driving operates in the operating stroke range (A) of the magnet, and the armature (26) which forms the control variable (x) operates in the idle stroke region (L) with its greatly changing inductance. The direction and magnitude of the deflection of the servo valve spool (16) can thus be continuously controlled using suitable switching magnets (22, 25). <IMAGE>

Patent DE-3119098-A1 (DE)
Title: Method and apparatus for continuously producing sheet materials
IPC: C25D1/12
Filed: 1981-05-14
Abstract: The electrophoretic production of sheet material from a particle suspension, in which said particle suspension is introduced into the space containing the counter electrode between two moving electrodes of the same polarity and the two layers deposited on the moving electrodes are combined to produce a sheet web after leaving the electrophoretic field, is satisfactorily possible only to a thickness of about 6 mm. In order to be able to produce thinner material webs than 6 mm by this method as well, after leaving the two moving electrodes, the material web is sucked by means of vacuum onto a discharge means and/or repelled by a positive potential of the electrode which is applied to the discharge means and which is greater than that of the electrodes. The discharge means comprise, as a rule, a conveyor belt which is of air-permeable construction and is provided with a vacuum device in the vicinity of the separation point. <IMAGE>

Patent DE-3200241-A1 (DE)
Title: Control wheel
Inventor: NIKLAUS BERND ING GRAD
IPC: B63H25/16
Filed: 1982-01-07
Abstract: A motor-driven control wheel in a water vehicle or land vehicle in conjunction with corresponding signal generators permits an automatic guidance of this vehicle. In sailing boats for example, the control signal takes place by means of the wind vane so that a constant travel direction with respect to the wind can be maintained via the control circuit. Since for safety reasons a manual actuation facility is required, known autopilot systems use electromagnetic or manually actuated couplings in order to decouple the motor with the usually self-locking gear in manual operation. Electromagnet couplings are expensive and require energy. Manually actuated couplings offer too little operating comfort. By means of the subsequently described control wheel with installed coupling, the abovementioned disadvantages are avoided. A control wheel provided with a pulley is proposed, which control wheel is attached to a drive shaft and is suitable both for manual and motor operation in both directions of rotation. With slight changes, it can also be used as a moment amplifier.

Title: Process for producing polystyrene foam boards
Inventor: KRAEMER HEINRICH
IPC: B29B17/00
Filed: 1982-04-22
Abstract: A process for producing a drainage board and a lathing board is described. For this purpose, after selective comminution, fragments of polystyrene foam scrap are softened in a press which can be heated by steam and are compressed to form a slab essentially in the form of a right parallelepiped. The slab, which obtains numerous voids if compression is low, is cut up into drainage boards once it has cooled. Polystyrene foam slabs produced by compressing by about 1/3 are cut up thermally, whilst still in the warm state, into lathing boards, the fissured surface of which forms a base surface to which a plaster can adhere.

Title: Dry gas meter
Inventor: BERTKE HEINRICH ING GRAD
IPC: G01F3/22
Filed: 1982-05-27
Abstract: In a dry gas meter, in which the movement of the diaphragms is transmitted via a linkage with a crank drive to a crankshaft which drives a counter, the connecting rod (38) of the crank drive is of elastically flexible design in the longitudinal direction. The connecting rod comprises a single injection-moulded plastic part. The elastic flexibility is achieved by the fact that the connecting rod is formed by sections (52 and 54) having lateral, mutually parallel arms (62 and 64). The arms are connected to one another by torsion elements (66). In a preferred embodiment, the crank arm (44) of the crank drive is likewise flexible, in the radial direction, with a spring constant considerably lower than that of the connecting rod (38), the radially inward spring travel of the crank arm (44) being limited. A description is given of a design of the crank arm (44) in which the crank arm (44) is produced from a single injection-moulded plastic part, is designed to be radially flexible as far as a stop but transmits forces in the circumferential direction in a virtually rigid manner. <IMAGE>
