Title: Method and Device for Protection of Metal Articles Against Chemical Metallisation
IPC: C23C18/16
Filed: 1980-11-03
Abstract: In order to prevent unintentional metallisation of metal articles in contact with electrolytes for chemical metallisation from taking place, an electrode (2) is immersed in the solution which is contacting the metal part (1) and a pulsed unipolar voltage is applied between the metal part and the electrode. This voltage possesses an amplitude exceeding a value in the phase of the polarisation curve for the metal part corresponding to initiation of passivation of the metal part. Application of the pulsed voltage is stopped when the potential difference between the electrode and the metal part which is measured in the zero intervals between pulses exceeds a given value within the range at which passivation of the metal part takes place and is only reapplied when this potential difference drops below a minimum value within the phase of the polarisation curve corresponding to initiation of passivation. <IMAGE>

Title: Fluid Velocity Meter
IPC: G01P5/08
Filed: 1980-11-07
Abstract: The flow velocity or flow rate of a fluid containing electrical charges or magnetic dipoles is sensed by receiving a noise signal generated by movement of the charges or dipoles, and determining the mean frequency of the received signal. For sensing electrically charged particles electrodes 14 are arranged around a pipe 10 of insulating material containing low conductivity fluid 12, alternate electrodes being connected by conductors 16, 18 to respective inputs of a differential amplifier at the input of mean frequency determining circuit 24. The amplifier output is connected directly and indirectly through a filter to respective squaring circuits, the filter multiplying the amplitude of the noise signal at any frequency by the square root of that frequency. The outputs of the squaring circuits are connected through smoothing circuits to a divider which supplies a d.c. proportional to mean frequency and hence flow rate electrodes 14 may be replaced by a pair of electrodes or a single electrode. If the fluid 12 contains magnetic dipoles coil(s) or Hall effect probes are used instead of electrodes. <IMAGE>

Title: Process and apparatus for charge-carrier beam machining or welding
IPC: B23K15/00
Filed: 1981-02-13
Abstract: A process for charge-carrier beam machining or welding, in which a focussed charge-carrier beam is directed, in a continuously evacuated chamber containing some oxygen- containing residual gas, onto a machining point of a workpiece, wherein there is introduced into the region gas which drives out the oxygen-containing residual gas in this region and which generates, at least temporarily, a protective-gas pressure of at least 5.10<-2> millibars. The gas e.g. Ar or He may form a curtain at 46 around the area between the beam exit aperture 22 and workpiece 40 so that the gas, not air, is drawn into the working chamber by the vacuum system 34, 36, 38, or the gas may be introduced by line 472 and shield 480 as a shot surrounding the beam and work region. <IMAGE>

Title: Apparatus for operating a discharge lamp
IPC: H05B41/292
Filed: 1981-03-19
Abstract: An apparatus for operating a discharge lamp provides a circuit (6) for generating a high frequency voltage for operating a discharge lamp (8). The voltage generated by this circuit (6) contains a fundamental wave component having a frequency within a range of 15.5 to 50 kHz (resonant circuit 30, 36, 38, 8) and a triple frequency component of this fundamental wave component (resonant circuit 31, 36, 38, 8), but it does not substantially contain frequency components above the triple frequency. A ratio I3/I1 of a lamp current I3 of the triple frequency component to a lamp current I1 of the fundamental wave component, both currents flowing through the discharge lamp (8), is so determined that 0.2 </= I3/I1 </= 0.6. This avoids instabilities in lamp operation. <IMAGE>

Patent GB-2126251-A (GB)
Title: Sintered plastic impregnated metal body
Inventor: GONZALEZ RICARDO
IPC: F16K1/42
Filed: 1982-09-14
Abstract: A sintered metal body, preferably of annular form suitable for use as a valve seat or seal, is impregnated with an uncured polymeric material such as PTFE which is then cured to partially fill the interparticulate spaces in the sintered metal body. The impregnated body is then subjected to pressure which preserves the shape while collapsing substantially all voids throughout the body to cause the cured polymeric material within the sintered metal body to completely fill the collapsed interparticulate spaces thereby to render the body nonporous throughout. Since the interparticulate spaces are completely filled with cured polymeric material, any increases in temperature cause a migration of portions of the polymeric material from the interior to the exterior to lubricate the exterior surfaces. The body may, also be covered by another layer of cured polymeric material.

Title: Emitter-receiver laser device and its application with a system of distant detection
Inventor: CORNILLAULT JEAN
IPC: G02F2/00
Filed: 1983-03-11
Abstract: An emitter-receiver laser device with heterodyne detection comprises a laser emitter (1), an optical separating lamina (6), a rotary shutter (11) and an optical system (10), aligned successively on the same axis (2), in order to form a beam of impulses (29) illuminating the target, and on the return axis (13) of the separating lamina (6) it has a crystal (14) which produces frequency shifting of the radiation (reference beam) and which is followed by a photoelectric detector (16) which also receives an echo (30) of the laser impulses returned by the target. The output of detector (16) is amplified by amplifier (22) and passed through an envelope detector (23) and amplifier (24) to undergo a syndronous detection at the modulation low frequency produced by the shutter (11). Parasitic retroreflections of the laser impulses from the optical system (10) do not confuse the detector (16) in this arrangement. <IMAGE>
