Abstract: @ The dynamic semiconductor random access memory of a computer stores the data for display in certain columns of all rows of the memory so that the addressing of the rows of the memory to produce the display serves to refresh the memory. The display is to be produced on a raster scanned cathode ray tube with 256 lines per field and either 256 or 512 picture elements per line with 4 or 2 data bits per picture element respectively. Conversion means is connected between the central processing unit and the memory to convert picture element coordinates on the raster to row and column addresses in the memory so that user addressing of the picture elements is simplified. When 2 data bits are used for each picture element these represent the green and red colour components and when both components are present this is detected and the blue colour component is also generated so that the picture element can be white, green, red or black. A serial data link is provided between the central processing unit and the keyboard so that only 2 conductors, one for control and one for data are required.

Abstract: A hermetic package for microelectronic circuits comprises a ceramic base (3l) with conductive, hermetically sealed vias (33) that connect the metal ground plane (43) on the bottom of the base (3l) to the circuit on the top, a ceramic frame (35) sealed to the top of the base (3l), leads (37) sealed between the frame and the base, and a lid (39) sealed to the top of the frame (35). The vias (33) are cofired with the ceramic base (3l) and provide good power dissipation because of their thermal conductivity and good RF grounds to isolate different stages in the circuit. Because the vias (33) are hermetically sealed, no separate bottom component and no brazing operation is required to hermetically seal the package. The leads (37) have a tapered section so the leads are wider outside the package reducing inductance and narrower going through the ceramic frame to reduce capacitance, thus tuning the leads to close to 50 ohm impedence. A layer (45) of conducting silver loaded solder glass underneath the lead (37) electrically connects the lead (37) to the circuit and seals the lead to the base (3l). A nonconducting layer (44) of lead oxide solder glass over the lead seals the lead (37) to the ceramic frame (35). The top surface of the frame (35) has a metallized layer (47) so that the lid (39) can be hermetically sealed to the frame by soldering.

Abstract: A fiber reinforced structural member comprises a shell element (13a) formed of a fiber reinforced material such as, for example, a fiber reinforced plastic, and a core element (a₂) having a large joining surface fixedly joined to the inner surface of the shell element (13a), and comprising one or a plurality of primary core elements (a₁) each formed of a fiber reinforced material such as, for example, a fiber reinforced plastic, in the form of a tube or a channel (11a) and internally filled with a filling material (12a) such as, for example, foam polyurethane. Since the shell element (13a) and the core element (a₂) are joined together over the large joining area, an external force applied to the fiber reinforced structural member is distributed over the large joining surface and hence the stress in the joining surface is reduced, so that the durability and reliability of the fiber reinforced structur­al member is enhanced.

Abstract: A magnetic read/write head (14) is mounted on a carriage (20) having a bore (36) therein. The carriage (20) is slidable along a stationary guide rod (40) which extends into the bore (36). A lead screw (24) threads into a nut (76) which is keyed to the carriage (20) so that rotation of the lead screw (24) moves the carriage (20) along the guide rod (40). A torsion spring (52) engages the carriage (20) and provides a force to bias the carriage (20) so as to eliminate any undesired clearance between the carriage (20) and the nut (76) and between the carriage (20) and the guide rod (40). The force is applied at an angle relative to the axis of motion (48) of the carriage (20). As the carriage (20) moves, the spring (52) is deflected, causing the angle of the force to change and the amount of the force to change. The spring (52) is oriented so that the total force directed parallel to the axis of the motion (48) of the carriage (20) remains constant. The amount of the total force is predetermined to minimize vibration of the carriage (20) and head (14). The carriage (20) is guided by the guide rod (40), not the lead screw (24), so that misalignment of the lead screw (24) does not affect the positioning of the head (14). A second guide rod (42) extends into a halfbore (38) in the carriage (20) to prevent rotation of the carriage (20) about the lead screw (24).

Abstract: A method which involves the isolation, analysis and characterization of dispersants present in motor oils is disclosed. The method is particularly useful in connec­tion with the characterization of high molecular weight polybutenyl succinimide dispersants present in finished motor oils so as to provide detailed information with respect to the starting material reactants needed to synthesize such dispersants. The method involves breaking down complexation present in the oil followed by the isolation of the dispersant from the oil via dialysis. The isolated dispersant in the form of a dialysis residue is then acidified and passed through an ion exchange chromatographic column to adsorb acid materials away from the dispersant. Dispersant content and total carbonyl content can then be determined. The dispersant is then subjected to saponification with sodium hydroxide to provide a hydrocarbyl sodium succinate and a polyamine. The saponified material is subjected to further dialysis to separate it from remaining oil and then further acidi­fied. The acidification results in the formation of a corresponding succinic acid and a dialkyl ester deriva­tive. Procedures such as GPC and VPO determinations can then be carried out. Model reactant components can then be prepared and reacted to determine if the reaction product obtained matches the original dispersant being analyzed.

Abstract: A ferrite phase shifter is described in which the switching circuit is arranged to apply a complementary setting pulse to a latching wire (4) of a toroidal ferrite phase shifter (2) before a resetting current pulse is applied by means of a latching wire (6). A new phase state is then set by a normal setting pulse applied to the latching wire (4). The complementary setting pulse is of a voltage sufficient to bring the magnetisation state of the phase shifter to an unsaturated magnetic state. This may be achieved by applying a complementary setting pulse of a voltage which together with the voltage of the previous setting pulse adds up to a constant amount. Alternatively, the magnitude of the complementary setting voltage may be determined on an empirical basis in order to reduce the phase error in any subsequently set phase. This may result in the unsaturated magnetic state varying in dependence on the previously set state.
