Patent DE-3029277-A1 (DE)
Inventor: SMOLA JAN
IPC: H05K1/03
Filed: 1980-08-01
Abstract: A conductor track which contains metal layers, mainly a Pd layer (Pd) under an electrochemically deposited Au layer (Au) on an insulating substrate (S) which is intended to carry semiconductor circuits. The Au layer is thinner than 500 nm. Such a conductor track structure allows the Au material cost, which is significantly high in the case of high quantities, for example in the case of 100,000 substrates per year, to be made low and ensures that the soldering properties of the conductor tracks are nevertheless not adversely affected, even soldering which is repeated several times if required being intended to be permissible, without the Pd layer becoming delaminated. <IMAGE>

Title: Wet fibre web press - has compressible sliding shoe to allow for variations in material thickness
Inventor: WIEDENMANN GEORG
IPC: D21F3/02
Filed: 1980-08-09
Abstract: The press to extract water from a fibre web, for conversion to paper, has a sliding shoe (8) of a material which can elastically compress and distort under roller pressure. It is held directly or indirectly by a fixed yoke (14) within the continuous impermeable band supporting the wet fibres. The sliding shoe (8) is made of rubber, secured to a metal foot (11) with grooves (12) where the shoe touches the foot. A fluid-filled pressure cushion (13) is placed between the metal foot (11) and the yoke (14) so that pressure is transmitted from the shoe to the second half of the pressure gap (S) in the direction of pressure roller rotation. The metal foot (11) has a radial guide (15) in the yoke (14) keyed to act on a tangential plane through the pressure gap, with radial limit stops (20). The pressure cushion (13) is divided into zones of different pressures. The press components are not affected by variations in material thickness or local uneven zones, giving an even lubricating film formation and safe operation.

Title: Density measurement esp. of small valuable articles - by accurate volumetric measurement of liq. displaced within cylinder
Inventor: TUEFFERS LOTHAR J
IPC: G01N9/02
Filed: 1980-09-11
Abstract: Appts. for determining the specific gravity of solid objects by volumetric measurement operates on the principle of flooding the object, instead of immersing it. A cylinder and sliding piston, together with a further removable cylindrical lid is used. In a first operation the lid is pushed down over the piston, the piston descending also into the cylinder, until the magnetic rings come into accurate contact. This determines the accurate geometry of the appts. and the contained liq., typically distilled water, now floods the entire internal vol. through the communicating duct, and ascends a certain way up the narrow calibrated pipe at the top. The reading on the scale is taken. From the known weight of the object, its density can be accurately calculated. Economical and small appts. for very accurate measurement of the vol. of valuable articles e.g. gold, silver, jewels etc. Surface tension of the liq. does not affect the result, since the only exposed surface is the very small area within the calibrated tube. Problems arising from bubbles adhering to the object disappear. The entire procedure takes only a few seconds.

Title: Remote-controlled bomb-defusing machine - has abutment winched towards drilling head adjustable for angle in guides
Inventor: ROOS HERMANN ING GRAD
IPC: F42B33/06
Filed: 1980-12-24
Abstract: The remote-controlled defusing machine allows the use of mechanically-driven cutting tools, and is partic. for police use. It has a movable drilling abutment (14) whose base is connected by guide bars (15) to the drilling carriage (1), the bars working in tubes (10) so that the abutment can be moved horizontally towards the carriage under the action of two steel ropes (12) from a winch drum (5). These ropes are so reeved and anchored as to secure the bomb in the abutment and apply the drilling pressure. The drilling head (2) can be tilted about an axis (9) and locked by a mechanism comprising a clamping screw (6), guide slot (7) and locking pin (8), so as to incline the drill bit (4) at any desired angle within set limits in a vertical plane. The clamping screw prevents deviation from the preset drilling direction during the drilling operation.

Title: Device for determining the altitude of an aircraft
Inventor: EVANS JAMES D
IPC: G01C5/06
Filed: 1981-02-12
Abstract: A novel and improved computer for determining the altitude of an aircraft exhibits a pressure transducer for measuring the atmospheric pressure at the location of the aircraft and from this solves a nonlinear altitude/pressure equation, taking into consideration the predetermined pressure on the ground. In connection with a time measurement, the calculated altitude is used for determining the vertical speed of the aircraft. The calculated altitude also defines an address in a memory circuit, the data of which, stored at such an address, are the grey code which is sent to third parties for purposes of flight monitoring. <IMAGE>

Title: High-speed loading and locking device for piggy back transportation of (trailer) vehicles
Inventor: LAEMMEL ALBERT
IPC: B60P3/07
Filed: 1981-04-11
Abstract: High-speed loading and locking device for temporary piggy back transportation of (trailer) vehicles, consisting of two sliding rails on the transport vehicle and two corresponding sliding rails on the vehicle to be transported, having a corresponding locking device, for easily loading, locking and letting off vehicles to be transported by a commercially available motor vehicle chassis with driver's cab (Figure 1, points 1, 2, 3). The sliding rails mounted on the transport vehicle have recesses or guides at the rear for supporting (holding) in a securely connectable fashion extension rails which are provided with sliding rollers and extend, with appropriate curvature, as far as the floor (Figure 1, points 4, 5). The corresponding sliding rails which are mounted on the underside of the vehicle to be transported are provided along the side to be pushed up with runners along the top. As a result, it is easy to push onto the extension rails which are provided with runners along the bottom (Figure 1, point 6). Sliding and corresponding sliding rails have corresponding fitting holes for two fixable locking rods with fitting notches (marks) for assembly to be plugged through with the appropriate lateral spacing of the sliding and corresponding sliding rails. The device according to the invention would make it very easy to transport in a "piggy back" fashion vehicles which would otherwise be trailers. The resulting possible popularisation of "piggy back transport" would contribute in many ways to avoiding the known dangers and disadvantages of trailers without having to accept the equally well known disadvantages of a mobile home. A commercially available small cable winch which can be mounted on the transport vehicle and has a non-return lock can serve to make loading or unloading still easier. <IMAGE>
