Patent DE-2801743-A1 (DE)
Title: Drop forged fork with extruded shank - esp. for cardan or universal joints used in motor vehicles or machines
Inventor: GUNGA HANS-DIETER
IPC: B21K1/74
Filed: 1978-01-16
Abstract: Drop forging is used to make a fork blank with a solid stock; deburring is then used to remove the flash along the forging line. The next operation is extrusion of a blind hole in the stock while the two prongs are clamped in a split die forming a cavity corresp. with the "H" shaped cross-section of each fork. The resulting component may then be hammered to a final profile. Extrusion of the blind hole replaces a drilling operation, which is therefore eliminated and the wt. of material in the blank is reduced.

Abstract: (Non)metallic surfaces are activated for electroless plating by contacting with (a) a soln. of SnF2, SnCl4.5H2O and HCl; (b) water of hardness >=10 degrees dH or an aq. soln. of Ca(HCO3)2, MgCl2 and Fe2(SO4)3; (c) a soln. of PdCl2 in HCl; and then (d) water, pref. tap water. Soln. (a) provides the surfaces with a uniform and high nuclei density and has a long working life when F- ions are present. Soln. nb) removes excess soln. (a) but has reduced solubility for the nuclei. In an example, the surface of a fired alumina ceramic substrate was etched in molten NaOH, rinsed, dried and then treated by (a) 1 min. immersion in a soln. of 7 g/l SnF2, 8 g/l SnCl4.5H2O and 40 ml/l conc. HCl; (b) 5 sec. immersion in water of hardness >=10dH (corresponding to a content of 100 mg/l CaO or equiv. Mg ions, combined with Cl, SO4 and HCO3 ions) at is not >15 degrees C; (c) 1 min. immersion in a soln. of 1 g/l PdCl2 and 10 ml/l conc. HCl; (d) 30 sec. immersion in water as in (b); and (e) drying with compressed air. The surface was active for 8-12 hrs.

Title: Earth specific resistance measurement - uses thin probe with two additional electrodes and employs source of known AC
Inventor: WOUDSTRA GERRIT
IPC: G01V3/06
Filed: 1978-03-10
Abstract: The method is for measuring the specific resistance of the top layer of the ground using a specially designed thin probe and two additional separate electrodes (6, 7). At least two thirds of the probe are covered with an insulating coat and the non-insulated metallic portion at the lower end is at least 15 cm long. The conducting portion of the probe is a tube with a max. diameter of 10 mm. A known alternating current (i) is passed between the first electrode (6) and the probe using the source (8) and a meter (9). The voltage (E) between the nearer electrode (7) and the probe is measured using the meter (10). The specific resistance (rho) is given by rho = f.E/i where f is a constant for the probe, and E and i are the a.c. voltage and current respectively.

IPC: B25B11/02
Filed: 1978-06-24
Abstract: In the manufacture of frames, particularly wooden frames, the glued faces have to be pressed together along the bevelled cuts. For this purpose a clamping frame is suggested which comprises a closed rectangular clamping frame consisting of a first frame portion (10) consisting of two limbs (10a, 10b) at right-angles to each other and a second frame portion (16) consisting of two limbs (16a, 16b) at right-angles to each other. The second frame portion (16) is displaceable relatively to the first frame portion (10) and the limbs (16a, 16b) of the second frame portion (16) project outwardly beyond the limbs (10a, 10b) of the first frame portion (10). On the outside of the limbs (10a, 10b) of the first frame portion and parallel thereto there are pull rods (18) which intersect at the corner of the first frame portion (10) and engage the projecting limb sections of the second frame portion (16). Clamps (22) can be applied to the sections of the limbs of the second frame portion (16) that project beyond the limbs of the first frame portion (10) as well as to the pull rods (18), which clamps are supported on the outside of the limbs of the first frame portion (10) and with which the second frame portion (16) can be tightened to the first frame portion (10). By means of such a clamping frame, frames of different size can be clamped simply and conveniently.

Title: Switch protection system with back-up cut=out - uses max. overloading which only causes destruction at given place and circuit remains disconnected
Inventor: RUNTSCH ERHARD ING GRAD
IPC: H01H71/12
Filed: 1979-06-11
Abstract: The protection switch has its fixed contact piece mounted on a conducting rail that acts both as an arc guide and as a terminal connection. The conducting rail has a waisted or reduced zone (28) adjacent to the contacting region (24) so that the rail melts preferentially at this reduced zone when a max. overcurrent flows. No other parts of the switch are damaged and the switch remains open after the waisted zone has melted. The waisted zone is a 'back-up' cutout. The waisted zone may be produced in several ways, e.g. by creating holes of various shapes or by recesses cut in the sides of the rail.
Patent DE-2924605-A1 (DE)
Inventor: JAUCH KARL
IPC: G07D7/1205
Filed: 1979-06-19
Abstract: The re-emitted light or the amount of light, reduced after absorption, of a test object (3) and a reference object (2) which are exposed to a single light source (1) is passed to one optical sensor (10, 11, 12) each with the aid of light guides (4, 5, 6). Arranged in the beam path to the optical sensors there are replaceable optical filters (7, 8, 9) having a narrow pass bandwidth. An analysis unit transforms the signals of the reference object (2) and the test object (3) for various working wavelengths by mathematical transforms, standardises these and converts them into a single variable which can be used for a highly significant Good/Bad decision. The analysis unit with its test program is used both to determine the most advantageous filters (7, 8, 9) and, after these have been defined, for distinguishing test objects. <IMAGE>
