Title: Method for solder attachment of components on printed circuit boards
Inventor: MUELLER HELMUT DIPL ING
IPC: B23K1/08
Filed: 1987-11-10
Abstract: The invention relates to a method for fastening components on printed circuit boards (2) during the production of printed circuit board assemblies having a mixed-fitment of components, the printed circuit board (2) initially being passed over a solder wave, as a result of which those components which are provided with connecting wires are soldered. Subsequently, the temperature produced on the component side of the printed circuit board by the solder wave is raised by additional heat-producing means (3, 5) fitted above the printed circuit board (2), to the extent necessary for solder which is applied for fastening of surface-mounted components melts again. In consequence, repeated thermal stressing of the components is avoided and it is possible to fit components of different embodiments in one operation. <IMAGE>

Title: Wireless telephone call memory
Inventor: MACKERT REINHOLD
IPC: H04M1/57
Filed: 1987-11-20
Abstract: When a telephone is unattended due to absence, it is of interest to the telephone subscriber whether persons from a fixed circle of persons wanted to reach him by telephone. The solution presented here, which does not require to be licensed and is non-chargeable, enables such calls to be stored and remotely erased without cost since no call connection is established. The device is maintenance-free, inexpensive, without subsequent costs and can be installed by anybody. The wireless telephone call memory detects the ringing signals of the telephone by means of an in-built microphone and supplies them via an amplifier circuit to the tone detection circuit which renders the device insensitive to interference. In a further step, the ringing signals are forwarded to a time coordination circuit which ignores the ringing sequence of the first telephone call but counts and evaluates the ringing signals of a new call made immediately thereafter. The subsequent memory block ensures that the calls are stored or erased and visually indicated via LED. The above-mentioned erasure of the memory is achieved by repeating the storage process. Example: first call reveals "subscriber absent". Second call following immediately after the first one, 4 rings result in LED No. 4 being lit. After the operator returns, this informs him that the person with whom ringing code "4" has been agreed wishes to be called back.

Title: Adjusting device (setting device) for sports bows
Inventor: KLAUS EMMERICH
IPC: F41B5/22
Filed: 1987-12-18
Abstract: A sports bow must be individually adjustable for the archer. The important feature in this case is the position of the arrow end on the bow cord, the arrow contact (2) and the arrow rest (3) on the arc centrepiece (5). Only one bow design has an adjusting device with the capability to adjust the arrow rest (3) horizontally and vertically and an arrow contact (2) which is actually fitted outside the arc centrepiece (5). In order to move this adjusting device to the rotation axis, the bow centrepiece of this design had to be suitably modified. This adjusting device can therefore not be fitted to other bows. The object of the invention was to produce an adjusting device which can be installed in the centrepieces of all designs (subsequently as well). The object was achieved according to the invention in that a cylindrical collar (1) with an eccentric hole for the arrow contact (2) is inserted through an elongated hole in the bow centrepiece (5), and is mounted there. On the rear side of the bow centrepiece (5), the bow support (3) is fastened adjustably to the arrow contact (2) by means of the holder (4). The necessary adjustments of the arrow contact (2) and arrow rest (3) can be carried out by rotating and/or horizontal displacement of the collar (1). <IMAGE>

Patent DE-3803876-A1 (DE)
Title: Jet engine combination
Inventor: WEBER FRANZ-JOSEF
IPC: F02K7/16
Filed: 1988-02-09
Abstract: The subject matter of the invention is an engine combination which is intended for supersonic flight and consists of a bypass gas turbine, a ramjet engine and a rocket motor. Up to an airspeed of Mach 3, thrust is provided by the turbojet. Further increase in thrust is not possible because of the low compression ratio of the gas turbine bypass flow. The object of the invention was to achieve an increased combustion-gas exhaust velocity and a greater air mass flow rate using the gas turbine compressor and to blank off the compressor against the ram air pressure at the airspeed of Mach 3. According to the invention, a longer diffusor is arranged between the high-pressure compressor and the bypass duct and high-temperature combustion chambers which are followed immediately by Laval or bell-shaped nozzles are arranged at the end of the bypass duct, which nozzles end at a specific distance in the inlet nozzle of the ramjet engine, the latter, as an annular engine, being the extension of the bypass duct. A truncated-conical rotary slide which closes the air inlet to the compressor at the airspeed of Mach 3 is arranged upstream of the compressor. The engine is intended to be used as a thrust engine for supersonic aircraft at airspeeds of up to Mach 30.

Patent DE-3822748-A1 (DE)
Title: Use of the p-nitrocinnamyloxycarbonyl (Noc) radical as amino-protective group
Inventor: KUNZ HORST PROF DIPL CHEM DR
IPC: C07K1/06
Filed: 1988-07-05
Abstract: The use of the p-nitrocinnamyloxycarbonyl (Noc) radical as amino-protective group, in particular for peptide and glycopeptide syntheses, is described. The p-nitrocinnamyloxycarbonyl (Noc) radical represents a valuable protective group which can be eliminated under neutral conditions. It has a higher acid stability than the unsubstituted allyloxycarbonyl group and has a strong UV absorption ( lambda max = 310 nm) which simplifies analytical monitoring even for solid-phase syntheses using the Noc protective group; in addition, almost all Noc-protected amino acids are crystalline. The Noc group is eliminated under virtually neutral conditions by palladium(0)-catalysed allyl transfer, using as a particularly effective allyl acceptor N,N'-dimethylbarbituric acid. In comparison with the rhodium(I)-catalysed elimination of unsubstituted allyl protective groups, the Noc group is stable so that it represents an important extension of the potential protective groups for synthesising peptides and glycopeptides.
Patent DE-3825956-A1 (DE)
Title: Eddycurrent rail brake
Inventor: BAUER LOTHAR DIPL ING
IPC: B60L7/28
Filed: 1988-07-29
Abstract: In the future, modern high-power trains will use eddycurrent rail brakes, which are fitted underneath a railway vehicle. These brakes consist of a magnet yoke having a plurality of pole shoes which are arranged one behind the other over the rail, are energised alternately in different directions spacially in the braking mode and induce eddycurrents in the rail. However, these brakes can influence signalling devices in an undesireable manner. This includes electronic pulse transmitters with transmission and reception circuits arranged on a rail on both sides in order to trigger axle counting pulses when vehicle wheels pass by. A cap is proposed in each case for covering the individual pole shoes, which caps consist of at least two non-magnetic metal sheets (1, 2) which extend in the rail direction, are L-shaped and are held at a predetermined distance (X). Eddycurrent rail brakes railway signalling technology. <IMAGE>

Patent DE-3900725-A1 (DE)
Inventor: WESTPHAL MICHAEL DR DIPL ING
IPC: A61B5/055
Filed: 1989-01-12
Abstract: A superconducting magnet arrangement of a nuclear spin tomographic apparatus comprises mutually coaxial metal tubes (1 to 9) in which eddy currents are induced when gradient fields are switched on. In turn, the eddy currents induce time-dependent magnetic fields which interfere with the gradient fields. To date, compensation of these interfering magnetic fields has proved only partly successful or prohibitively expensive. According to the invention, a shield (13) made of a material which is an excellent conductor of electricity, with a wall thickness not greater than 10 mm, or of a superconducting material is arranged in the region of the helium tank (10) of the magnet arrangement. All other tubes (1 to 9) of the magnet arrangement are made from a material which is a poor conductor of electricity, so that at the operating temperature of the magnet arrangement, the conductivity of the shield (13) is at least ten times the conductivities of the other tubes (1 to 9). The shield (13) generates an interference field of given magnitude and time constants, which, if necessary, can be easily compensated electronically.

Title: Wagon drill with laser-orientated control
Inventor: ECKER ROBERT
IPC: E21B7/02
Filed: 1989-01-25
Abstract: For heading by blasting, in particular in underground mining and tunnelling, a wagon drill is provided which works in a fully automatically controlled manner in accordance with a predetermined blasting pattern. To this end, a sensor with laser-beam receiving zone is allocated in the underframe. The laser-beam receiving zone or the entire sensor can be vertically adjusted via a hydraulic cylinder so that the laser-beam receiving zone can be put into the laser beam without changing the position of the wagon drill itself. The sensor is connected to a microprocessor in which the requisite blasting pattern is stored and via which the drilling carriage is correspondingly controlled. Furthermore, the information determined for monitoring at all pivot points and longitudinally displaceable points collects in the microprocessor so that a continuous plausibility check is possible. A substantial reduction in the drilling time, in particular the re-setting time, and operations running in parallel can be achieved with a wagon drill of this type. <IMAGE>

Title: Speed measuring method
Inventor: BAEUMER KLAUS DIPL ING
IPC: G01P5/20
Filed: 1989-03-23
Abstract: In a method or a device for contactless measurement of speeds, speed distributions and decomposition (decay) frequencies in liquid jets and flames, two light beams of an intensive light source are focussed in the measurement volume of a layer of liquid or flame in such a way that it is possible to use two light-sensitive detectors to measure the transmission of the light in the case of a focal distance of DELTA s in the measurement volume. The temporal shift of  DELTA t in the transmission curves is used, with v =  DELTA s/ DELTA t to obtain speeds and speed distributions in injection jets and flames. Furthermore, the temporally detected transmission curve can be used for the purpose of conducting frequency analysis investigations with the aid of digital Fourier analysis (FFT analysis). The wavelength lambda  which determines the globe magnitude in liquid jets and flames can be determined using the wave equation   lambda  = v.f from the speed v or the temporal variation in the speed in the layer of a liquid or a flame as well as from the frequencies f which have been determined from the frequency spectrum. <IMAGE>
