Patent DE-3005230-A1 (DE)
Title: Radar apparatus for locating helicopters - uses field strength distribution of reflected EM wave and detects threshold valves of demodulated signals
Inventor: HEIDEN DIETMAR ZUR DIPL ING
IPC: G01S7/41
Filed: 1980-02-13
Abstract: The radar location system consists of a transmitter producing signals that are fed to an antenna system, via a transmit/receive dividing network. The received signals pass from the antenna through the divider to a mixer which also receives a signal from a mixer oscillator, this combined signal passing through an amplifier to an amplitude demodulator and following filter. The pass band of the filter is chosen dependant on the expected modulation frequency, -in this case, 15, plus or minus 5 HZ-, the output from the filter then taken to a threshold value circuit. If the signal has a sufficiently large amplitude, a helicopter target is indicated by display equipment. The system recognises fluctuations in the field strengths of signals reflected from the helicopter as amplitude modulation, and is able to distinguish even slow moving blades from fixed targets.

Title: Electroless copper-nickel phosphorous plate - with low phosphorus content and wide range of copper contents
Inventor: OSTWALD ROBERT DR ING
IPC: H05K3/24
Filed: 1980-09-16
Abstract: The electrolessly deposited Cu-Ni-P layer contains less than 20 wt.% P and 0-99 wt.% Cu and is deposited at a low, uniform deposition rate from a soln. contg. two different complex formers (pref. a mixt. of di-sodium EDTA and a hydroxy polycarboxylic acid) in a ratio dependent on the selected Cu:Ni ratio, at pH 6.0-13.0 and at below 80 deg. C. The deposit is post-heat treated (pref. at about 300 deg. C in an inert gas atmos) to stabilise its properties. The layer is esp. useful in integrated circuits. The low phosphorus content improves the solderability of the layer and the layer has precisely controllable electrical properties, good long term stability, has a positive temp. coefft. of resistance of about 100 ppm/K in the range -55 to +125 deg. C, and a resistivity in the range 50-300 micro-ohm. cm. The plating soln. can be used at room temp. so that the formation of islands in the deposited layers is avoided and the pH of the soln. can be changed to modify the Cu content of the deposit without affecting the deposition rate.

Title: Sorting machine for materials of different magnetic property - has sieve conveyor with movable magnet for simultaneous or successive use
Inventor: ZIMMERMANN OTHMAR
IPC: B03B9/04
Filed: 1980-11-15
Abstract: The materials of different magnetic susceptibility are separated during the conveyor stage by a grading sorter in the form of a sieve (1) with a magnet (2) whose position relative to the ejector end (10) can be altered. This enables sorting and grading of the different materials simultaneously or in succession. During simultaneous sorting and grading the magnet is mounted above the sieve. Where grading immediately follows sorting a separate intermediate conveyor is unnecessary thus avoiding additional wear on the material in a transitional area.
Patent DE-3046267-A1 (DE)
Title: Alternating pressure adsorption of several differing crude gas streams - using separate adsorber groups cross connected at outlet side
Inventor: BENKMANN CHRISTIAN DIPL ING
IPC: B01D53/04
Filed: 1980-12-09
Abstract: Two or more crude gas streams of different compositions are broken down in a single adsorption plant comprising a number of adsorbers operated cyclically with pressure changing; each cycle includes an adsorption phase and a regeneration phase comprising expansion, scavenging and repressurising. For each crude gas stream there is a group of adsorbers, through which the stream is conducted and decomposed; each adsorber belongs to only one group and, at least during a stage of expansion, the expansion gas produced in an adsorber which is in the regeneration phase is conducted to another group. Used for decomposing several gas streams of different compositions. The process makes optimum use of the available adsorbers and results in high efficiency for a given size of plant. This is due to the particularly high yield of the non-adsorbed components, resulting from a more detailed breakdown of the regeneration phase into individual steps. The basic feature is that groups of adsorbers are connected together at the outlet side. One typical application includes the obtaining of hydrogen from a hydrogen-hydrocarbons mixture with steam reforming of the hydrocarbons, followed by adsorptive separation of the hydrogen produced.
Patent DE-3105263-A1 (DE)
Title: Vehicle jack
Inventor: WEISSER DIETER DIPL ING
IPC: B66F3/12
Filed: 1981-02-13
Abstract: The vehicle jack is equipped with a standing leg which is linked at a fixed transverse pivot axis to a supporting arm which carries at its free end a load head which can be attached to the underside of a vehicle body. The supporting arm can be pivoted by means of a threaded spindle which is mounted in an articulated manner on the top end of the standing leg and on the supporting arm via a spindle nut on the one hand and a spindle abutment on the other hand. Starting from the bottom pivoted end position of the supporting arm up into a position relative to the standing leg in which the load head of the supporting arm is located in the area of the vehicle base, the threads of spindle nut and threaded spindle are mutually disengaged. This ensures that the user of the vehicle jack is forced to move the supporting arm first of all into its load-receiving position before attaching it to the motor vehicle so that it is no longer possible to insert a support between the mounting surface of the motor vehicle and the mounting foot of the standing leg in order to accordingly shorten the idle pivoting path of the supporting arm to be covered until load is received. <IMAGE>
Patent DE-3108355-A1 (DE)
Inventor: GARTNER KARL
IPC: F24F13/02
Filed: 1981-03-05
Abstract: Apparatus for use in heating, ventilating, cooling and/or regulating the temperature of rooms in a building including a facade which comprises a framework of hollow posts and hollow girders is distinguished by sections of the hollow posts and hollow girders being connected to one another in flow, in fixed manner, for the conduction of a heat transfer fluid and an air stream between a delivery line and a return flow line. A distinguishing feature is that the hollow posts are constructed in two pieces or parts, each of which parts includes two channels one of which provides for the conduction of a heat transfer fluid and the other for the conduction of a further fluid such as an air stream. In the preferred form illustrated the post parts are made to be generally C-shaped in cross section. As thus provided the C-shape cross section of each part shows that it includes a double-walled base leg portion incorporating both the channel for the heat transfer fluid and a channel for further fluid. By virtue of the C-shape of the cross section of each part, two such parts, each of which exhibits freely projecting legs, are coupled through the medium of the legs along their length to define one hollow post. The two part construction of the post provides for connection of girders to each part in a manner that girders may tightly connected to the post in directly aligned pairs.

IPC: F16K27/07
Filed: 1981-03-12
Abstract: The outlet slide valve is provided with a piston-shaped, axially displaceable shut-off member (18) which is guided in a guide element (14) of generally tubular, in particular hollow-cylindrical, form. The guide element (14) ends in an opening (12) which is to be closed. Branching off to the side of the tubular guide element (14) is a conduit (16) which leads, for example, to a sampling container. The shut-off member (18) can be expanded in the radial direction and, in its closed position adjoining the opening (12) to be closed, can be brought into sealing engagement with the inner surface of the guide element (14). In the closed position, the end face (20) of the shut-off member (18) is essentially in alignment with or flush with the inner surface of the wall (10) bounding the opening (12), thereby precluding projections or recesses at which residues might accumulate. <IMAGE>

Title: Device for separating the topmost paper sheet of a paper sheet stack
Inventor: KUESTER RICHARD ING GRAD
IPC: B65H3/08
Filed: 1981-03-20
Abstract: The invention relates to a device for separating the topmost sheet (7) of a paper sheet stack (1), which possesses a separating suction apparatus (2) movable perpendicularly to the paper sheet stack (1). This separating suction apparatus (2) lifts the topmost paper sheet (7) from the paper sheet stack (1). The device also possesses a further-transport apparatus which is actuated by suction air and transports the paper sheet (7) in the sheet-conveying direction (3) at a specific distance above the paper sheet stack (1). So that the topmost paper sheet (7) of the paper sheet stack (1) can be reliably picked up and lifted, the separating suction apparatus (2) has a suction plane (10) which both extends to a large extent across the width of the sheet stack (1) and is also distributed in the sheet-conveying direction (3) with a multiplicity of suction openings (6). <IMAGE>

Title: Cutting device for double fabrics in or outside weaving or knitting machines
Inventor: HEESEN HANS NORBERT
IPC: D03D39/18
Filed: 1981-03-24
Abstract: The cutting knife, stationary or rotating, is mounted on a carriage which moves at a constant speed over a continuous guide rail. This guide rail, made of metal or plastic, is constructed in such a way that the carriage is guided in the fabric in a vibration-free and straight manner. Outside the fabric, the guide rail describes a semicircle and then guides the carriage along a straight line and subsequently, again by way of a semicircle, back to the straight rail which leads through the fabric. Arranged parallel to the semicircles of the guide rail are wheels of equal diameter, over which is stretched a rope, chain, ribbed belt or the like, to which the carriage is fastened by means of a driver. One of these wheels is driven by means of a direct connection to the weaving or knitting machine or by means of a motor. Two cutting carriages, for example, can be mounted on the guide rail, the rotational speed of the carriages being halved. Double the cutting capacity is thereby achieved at half the cutting speed. <IMAGE>

Title: Coupling circuit for frame antennas
Inventor: BRANDT HANS-JOACHIM
IPC: H01Q7/00
Filed: 1981-03-26
Abstract: The present invention relates to a frame antenna (RA), consisting of a frame as an inductance and of a tuning capacitor (C1), which is connected between the frame connecting points (1, 1'), as a capacitance, having a balanced input supply via an impedance converter (IW) whose two secondary supply lines are passed to the frame connection points via in each case one coupling capacitor (C2, C2'). In order to ensure automatic matching over a relatively large frequency range during the resonant tuning process, it is proposed to construct the two coupling capacitors as fixed capacitors. Furthermore, one or more four-pole networks (VP1, VP2) are connected in series with the impedance converter, in the direction of the two coupling capacitors. In this case, each four-pole network (VP1) has in each case one further fixed capacitor (C3, C3') in its two longitudinal branches and an inductance (L1) in its transverse branch. A frame antenna which is equipped with the coupling circuit according to the invention is particularly suitable for use as a transmitting antenna in the short-wave (high-frequency) band. <IMAGE>

Title: Wind power rotor
Inventor: MAUTZ KARLHEINZ
IPC: F03D80/00
Filed: 1981-04-15
Abstract: The invention relates to a wind power rotor having at least one rotor blade which can be pivoted over a range of flapping angles limited by stops and for the purpose of setting the angle of incidence is connected to the rotor shaft or rotor head such that it can rotate about its longitudinal axis. In this arrangement, a variable limitation of the flapping angle is achieved according to the invention by constructing the stops to be adjustable and providing them with an assigned control system which is active while the rotor rotates and varies the range of flapping angles in terms of position and magnitude by appropriate setting of the stops. In this way, the range of flapping angles limited by the stops closely tracks the flapping vibration zone of the rotor blades which is determined by dynamic loads, and each rotor blade is locked in an impact-resistant manner in a prescribed angular position when the rotor blade comes to rest and starts up.

Title: Absolute measurement of the electrical conductivity and of the magnetic permeability without calibration standards
Inventor: BECKER RAINER DR RER NAT
IPC: G01R27/02
Filed: 1981-05-22
Abstract: To characterize the material properties of a test object, the electrical conductivity and the magnetic permeability are utilised which are determined from the measured impedance of a test coil by means of an eddy-current test. The aim is to achieve an absolute and mutually independent determination of the conductivity and of the permeability even in the case of highly permeable materials, without calibration standards. For this purpose, the permeability of the material is reduced by premagnetisation at a low test frequency of, for example, </= 5 kHz, and the conductivity is thus determined whilst the permeability is determined without premagnetisation at a higher frequency of, for example, 1 MHz. Conductivity and permeability are thus obtained by comparing the measured impedance values of the scanning coil with stored values, the correlation of which with the conductivity/permeability pairs is known from numeric calculations or from measurements on samples having defined electrical and magnetic characteristics.

Title: Slide or slide-and-tilt fitting for wings of windows, doors or the like
Inventor: RIEDEL WERNER
IPC: E05D15/58
Filed: 1981-06-04
Abstract: On the slide or slide-and-tilt fitting for wings of windows, doors or the like, there are arranged on the wing underside running rollers which run on rails fastened along the fixed frame and which can be shifted in the direction of run of their roller axes. To control a locking slide and, if appropriate, tilt position of the fitting, there are fastened to the wing longitudinally movable espagnolettes which can preferably be actuated by a common handle. A setting-off device controlled by the espagnolettes changes the wing over between a press-down position moving it up against the fixed frame and a set-off position. In order to make the setting-off device more space-saving and less susceptible to faults, the latter is formed, with the incorporation of the rollers (13), in that the portions (23) of the espagnolette (20) which are guided past in the region of the running rollers (13) are provided with cam surfaces (25, 26, 27) which, during the longitudinal actuation (29) of the espagnolettes, act on the running rollers (13) with the effect of a shift (30) of these. <IMAGE>
