Title: Nickel plating baths with low nickel concn. - contg. magnesium and chloride ion, give ductile platings with low internal stress
IPC: C25D3/12
Filed: 1976-12-31
Abstract: Nickel electroplating baths are made with a nickel ion concn. of 0.1-0.9 gram ions/1 Ni2+, sufficient of a magnesium salt to give a ratio of Mg2+/Ni2+ of 0.05-15, and a Cl- ion concn. of 0.1-5 gramion/l.

Title: Connection link measuring system - determines shortest path between two points in X-Y matrix using clock pulse sequence interrogation
IPC: G06F17/50
Filed: 1980-02-07
Abstract: This conputer-controlled system works out the shortest connecting link required to join two points in an X-Y matrix. Each point in the matrix is connected to an individual circuit which can interrogate its adjacent points to find the finish point of the link, and a memory to record the direction from which the interrogation signal came. At the start of the operation (n=O), the start point interrogates the four adjacent points, to ascertain if one of them is the finish point, and blocks them to further interrogation. At the next clock pulse (n=1) each of the four points interrogates its unblocked neighbours. This process continues, spreading across the matrix on a diamond-shaped front until the finish point is located. At this point the computer uses the elapsed time and the direction memories to calculate the length of link required.

Patent NL-9300786-A (NL)
Title: Apparatus and measuring method for modifying an interferometer into a quantitative dual-channel phase quadrature interferometer, and the Michelson interferometer thus modified
IPC: G01N21/45
Filed: 1993-05-07
Abstract: The invention relates to an apparatus and associated measuring method for the modification of an optical interferometer for quantitative definition by repetition of the instantaneous wavefront distortion caused by an unsteady phenomenon in the test beam of the interferometer. The modified interferometer system generates phase quadrature interference patterns along two optical channels and is connected via an interface to a computer system. This interface comprises, separately for each optical channel, a detector and a digitization apparatus, the reciprocal synchronization of which guarantees simultaneous digitization of pairs of phase quadrature interference patterns from the unsteady phenomenon. The interface also performs the translation of a mirror in the interferometer over fractions of wavelength of the laser light used in order to calibrate the two optical channels prior to a measurement. Finally, with specific computer software, the wavefront distortion in the test beam is defined in an unambiguous manner from each digitized pair of phase quadrature interference patterns using the calibration data for the two optical channels. The invention offers a "multi-channel" interferometer system of minimum scope in terms of the number of optical channels in the interferometer, the number of detectors, the number of digitization channels and, for storage of the digitized interference patterns in a computer, also imposes minimal requirements in terms of the speed and size of the computer memory. Furthermore, through the use of a polarizing subcube (corner cube) as a "spatial phase-shifting" mechanism, the invention offers a spatial division between the two orthogonal optical channels over a relatively small distance, thereby permitting the use of a separate detector for each channel. Furthermore, the image distortion in the two optical channels is identical, as a result of which a perfect reciprocal alignment of the interference patterns is achieved.

Title: Positive displacement diaphragm pumps employing displacer valves
Inventor: LINDNER GEORG HEINRICH
IPC: F04B53/10
Filed: 1984-12-07
Abstract: A positive displacement pump (310) utilizes at leastthree driven displacer valves (360,362,364) and a plurality of driving membranes (336,340,344) and at least one pumping membrane (316) to withdraw minute quantities of corrosive fluid from a drum (100) and discharge same to a delivery point (128). The pump (310) is submerged within the fluid to be pumped and is driven by a remotely positioned pneumatic pulse generator (116) comprising pneumatic logic circuitry. The driven displacer valves (360,362,364) operate in a particular sequence to draw fluid into the pump body (312,314), advance same in succession through pumping chambers (318,320,322) within the pump body (312,314), and then discharge same at a constant rate of discrete pulses through an outlet port (332). The pulse generator (116) and logic circuitry provide the control pulses for operating the displacer valves (360,362,364) at the proper times in the operational cycle. The delivery characteristics of the pump far exceed the performance capabilities of conventional pumps utilized for similar purposes.
