Title: Method and apparatus for metal plating of cylindric bores with large diameter extending across the central part of a work piece having large dimensions
Inventor: COULON ANDRE
IPC: C25D7/04
Filed: 1981-03-20
Granted: 1983-12-15
Abstract: A method and apparatus for depositing a metal on a large-diameter cylindrical bore which passes right through the central portion of a large part. The invention consists in placing and centering the large part (1) between an upper tank (4) and a lower tank (3), so as to define a chamber (8) inside which the bore (2) is disposed and outside which the peripheral portions (9) of the part (1) extend, said chamber being filled with electrolyte. The electrolyte is homogenized and regenerated continuously outside the chamber (8) before being injected in the chamber (8) and before being entrained in a spirally descending motion to the level of the bore (2). The metal deposit takes place under the effect of a direct current which circulates between metal anodes (14) disposed in the bore (2) and the part (1) which serves as a cathode. The invention is used for depositing nickel on the bores of turbine rotor wheels so as to adjust dimensions or prevent fretting corrosion.

Title: A dual component mixing package
Inventor: KLECKERS BENT
IPC: B65D81/32
Filed: 1981-10-07
Granted: 1985-02-28
Abstract: In a dual component packing of the type consisting of a flexible bag, which contains the single liquid components in respective separate compartments, from which they may be brought together into a common mixing compartment by exterior manipulation, a mixing stick is mounted inside the packing so as to be seizable at one end by squeezing together the bag sheet material thereabout, whereafter the free end of the mixing stick by exterior manipulation can be moved around in the mixing compartment for effectively stirring and mixing the combined liquid components. Exterior pressure manipulations on the bag itself will be superfluous, and for this reason a packing of a simple flat bag type may be bottomwise designed so as to assume a cup shaped form when placed on a substantially planar support surface, whereby an effective mixing stirring by means of the said mixing stick is achievable.

Granted: 1985-03-07
Abstract: A diecasting process for producing cast pieces for metals or their alloys by means of a horizontal cold chamber diecasting machine. The diecasting machine includes a diecasting mold held under a vacuum, a fill chamber coupled to the diecasting mold, a holding furnace containing metal melt, a suction pipe partially immersed in the holding furnace and coupled to the fill chamber, means for transporting metal melt from the holding furnace through the suction pipe into the fill chamber under a vacuum, and means for moving the metal melt from the fill chamber into the diecasting mold. During the dosaging phase when the fill chamber is filled with metal melt, gases and lubricant vapors are developed upon entry of the melt into the fill chamber. The process includes the steps of maintaining the vacuum in the fill chamber during the dosaging phase until the gases and lubricant vapors so developed have been substantially extracted and maintaining the vacuum in the fill chamber to its maximum extent until the diecasting mold is completely filled with the metal melt.

Abstract: PCT No. PCT/CH82/00128 Sec. 371 Date Aug. 16, 1983 Sec. 102(e) Date Aug. 16, 1983 PCT Filed Dec. 3, 1982 PCT Pub. No. WO83/02340 PCT Pub. Date Jul. 7, 1983.The liquid crystal display cell (21) indicates the date in an aperture situated at 12 o'clock. The hour wheel (31) and the center wheel (29) present coaxial pipes which pass through the dial and bear hour and minute hands. These wheels are driven by a wheel-train (30, 28, 27) actuated by the stepping motor (25) which receives its pulses from the circuit (23) controlled at a frequency of 1 Hz for example by the quartz (48). The 24-hour wheel (33) bears a contact element (46) which, once per revolution, grounds the terminal (47). The pulse which results therefrom is transmitted to a counter incorporated in the circuit (23). This counter controls the decoding circuit which controls the display cell (21). To effect the setting of the date, the stem (35) is brought into its intermediate position (II). The contact element (40) borne by the yoke (38) then grounds the terminal (41), which causes in the circuit (23) the emission of pulses at a frequency of 1 Hz which controls a repeated and rapid change of date.

Abstract: The invention relates to attachment of metal edge strips to a sliding glass sheet for an automobile, the function of the strips being to guide or hold said sheet. Edge strips are attached to a sliding glass sheet by means of an adhesive which has high adhesion to glass, such as an adhesive comprised of polyurethane with other components. According to the invention, the adhesion of the adhesive to the edge strips is enhanced by furnishing the leg of the strip, which contacts the adhesive, with apertures, grooves, notches, channels and hollows. It has been found that the contact surface between the adhesive and the leg is at least twice as important as that between the adhesive and the glass.

Abstract: Circuitry for a fault-tolerant computer is disclosed which circuitry is constructed in two identical halves. Each half, by itself, is not a functionally-complete circuit, however, the two identical halves can be connected together to provide a functionally-complete circuit. Each of the two circuit halves is considerably less complex than a functionally-complete circuit yet, when connected together, the two halves provide fault detection capabilities equivalentto a computer system in which the outputs of two functionally-complete, redundant circuits are compared to detect faults.In particular, each inventive circuit half contains a complete data processing and control unit but only one half ofthe memory which is necessary for a functionally-complete unit. The processing units on each circuit half operate simultaneously on identical data and the same address information is provided to the memories on each circuit half.To provide error detection, address information and data sent from each control unit to its associated memory is acom- pared between circuit halves. In addition, information provided to the circuits over an external bus or generated by the control unit is encoded with an error-detecting code.

Abstract: An encrypted video distribution system includes a signal- originating head end for scrambling outgoing television program-bearing signals. In particular, the video content of selected lines is inverted about a reference voltage level, and the inversion reference level amplitude transmitted in pulse form during the horizontal synchronizing pulse interval. Line video inversion/non-inversion is controlled by a keyed pseudo random generator.At each authorized subscriber location, all inverted lines are restored to proper format, using the accompanying received inversion amplitude level present during horizontal sync as a reference. A pseudo random generator is included in the receiver descrambling circuitry and operates in a sequence identical to the like circuit atthe head end to identify those lines requiring video inversion.

Abstract: A method for measuring intensity fluctuations of an electromagnetic signal of wavelength between about 350 nm to 1200 nm from a liquid medium autocorrelates the intensity of the signal over a non-zero interval the duration of which is short compared to the mean duration of the fluctuations. Preferably the duration of autocorrelation is between one third and one hundredth of the mean duration of the flucutations. The method has particular applications in the diagnostic area, particularly where such fluctuations are a result of the presence of fluorescent particles in a liquid medium. Methods are also disclosed for determining an analyte in a sample suspected of containing such analyte.
