Abstract: ABSTRACT           The invention relates to a process of deposition of a coating of a gold compound on a solid substrate.  In a vacuum chamber (1), the substrate is fixed on a first sub-strate electrode (2).  A composite target (5) essentially consists of gold and at least one of the metal compounds, such as nitride, carbide and boride of the metals of group IV b of the periodic classification of elements and tantalum. A high-purity argon atmosphere at pressure ranging between 4x10-4 and 3x10-2  Torr is then established in the chamber.          The deposition of the coating is then carried out by ionic deposition or evaporation in vapor phase at a given rate.          The invention may find application to coat articles of jewelry or of watch cases.

Abstract: ABSTRACT            A device at an electromechanic platform scale with an inherent stable platform (1-3), the supporting points of the platform against the foundation provided with load measuring means in the form of substantially horiz-ontal beams with load sensing cells (4), each of which transduces part of the load of the platform to an electric signal.          It is characteristic of the device that one end of each beam is connected to the platform (1-3) so that the conn-ection (7,8,9) is rigid in vertical direction and elastically resilient in horizontal directions, at least in the direction perpendicularly to the longitudinal axis of the beam, and that the other end of the beam is connected to the foundat-ion (19) of the platform so that the connection (10) is elastically resilient in both vertical and horizontal direct-ions as well as to moments about axes in corresponding planes.          Owing to this design, the load tends to be distributed uniformly between the supporting points in the case of un-even foundations, and horizontal impact loads are reduced to riskless sizes, and simultaneously the platform is stable in lateral direction.

Abstract: Process for preparing copolymers Abstract The invention relates to emulsion polymerization of an .alpha.-alkylstyrene and an unsaturated nitrile copolymeriz-able therewith to form a copolymer having good heat-resistance.  The monomers are reacted in a weight proportion of 70 : 30 to 80 : 20, respectively, in the presence of a radical initiator, and the monomers are introduced into the reaction system in such a manner that the concentration of the unsaturated nitrile remaining unreacted in the reaction system is not less than 31 % by weight of the entire amount of the monomers remaining unreacted in the reaction system at the completion of the introduction of the monomers.  The resulting copolymer of the .alpha.-alkylstyrene and the unsaturated nitrile has good thermal resistance and is produced with a marked decrease of the monomers remaining unreacted.

Abstract: ABSTRACT OF THE DISCLOSURE     APPARATUS FOR GENERATING RECIPROCATORY MOTION     Apparatus for generating linear motion comprises a body on one end of which is mounted a cylinder.  A piston in the cylinder is joined to an actuating beam extending into the body.  The actuating beam has moving surfaces that cooperate with fixed surfaces in the body to define a linear  bearing.   Fluid under  pressure  is  introduced through a duct in the body to a port in the fixed surface of the linear bearing.  It enters the space in the cylinder above the piston via a port in a moving surface of the actuating beam which leads to a duct in the actuating beam that opens through the crown of the piston.          A resilient sealing member between the fixed and moving surface  of  the linear  bearing maintains fluid-tight communication between the fixed and movable part over their range of relative movement.  The actuating beam may carry a rack that drives a pinion through ninety degrees as the piston travels, and two opposed cylinders may be provided to give a reciprocatory movement, or a spring return may be provided.

Abstract: ADAPTIVE COMPASS AND NORTH STABILIZATION DRIVE SYSTEM                Abstract of the Invention This system accepts compass outputs from a wide variety of compass output devices such as stepper and synchro devices having different coupling ratios, supply voltages and carrier. frequencies.  The system then, as part of a PPI radar system, electronically converts these compass outputs without the usual intermediary electromechanical devices into real-time analog reference signals properly phased with respect to the radar timing to provide an electronically stabilized PPI.          This is achieved by selecting for comparison the points of equal amplitude of any two phases of gyro compass synchro output signals and using these major transition points to provide a digital code indicating the angular position of the gyro output shaft; a microprocessor then transforms the code, by comparison with a previously stored position code into coded position change signals which are then used to change a stored angular value, representing the course of the ship.  These coded angular data are converted to analog sweep reference outputs applied to the deflection circuit of the display to provide a stabilized and oriented PPI display.     In cases where synchro coupling ratios are used, resulting in smaller angular changes in the synchro shaft position for a given change in course, minor transition points can be inserted between the major transition points to provide the correct step changes in the orientation of the PPI.

Abstract: ISOLATOR FOR USE WITH FREQUENCY RESPONSIVE           SWITCHING CIRCUIT                    ABSTRACT OF THE DISCLOSURE     A frequency responsive power control system includes an improved isolator in series electrical connection with respect to a ballasted lamp load.  The isolator has a high inductive impedance at low current for blocking ballast induced noise signals from interferring with proper operation of frequency responsive switching circuits in the system.  In a particularly useful embodiment, the isolator is inductively matched to the capacitive characteristic of the ballasted lamp load so that the isolator-load circuit combination is resonant at a frequency sufficiently removed from any of the control system activation frequencies so as to block any noise signals induced by the ballasted load which might otherwise cause undesired activation of the switching circuits and flickering of the ballasted lamp loads.  Under saturation current, with the switching circuit conducting, the isolator functions collectively with the load to provide an impedance which blocks control signals from reaching the load.

Abstract: ABSTRACT: "Digital data apparatus with memory selection."     Digital data apparatus comprising a processing unit which can have access to different numbers of memory units over a common data bus. The processing unit can address the memory units with select signals over individual leads of an address bus. Address codes containing select signals are valid when they select only a single memory unit. The validity of an address code is determined in the processing unit by comparing it with a corresponding iden-tification code read over the data bus from a memory unit addressed by the code. Because an address code containing more than one select signal may select more than one memory unit, each address code has associated with it a number of flag bits which signify how many select signals the address code contains, and the corresponding identification code includes these flag bits. When an address code selects more than one memory unit there will be conflict on the data bus between the address code portions of the read identification codes. However, the flag bit portions of these read identification codes are not in conflict and can be compared with the flag bits associated with the address code being used to determine whether or not this address code is valid. Figure 4 shows certain logic elements in the processing unit for the performance of the invention
