Abstract: The present specification provides a total synthesis of known intermediates useful in the synthesis of khellin and antiatherosclerotic analogs thereof. 3-Furoic acid is treated with succinic anhydride and diesterified to 3-carb- oxy-8-oxo-2-furanbutanoic acid bis (alkyl ester). Following amination, cyclization and bis methylation, 6-formyl-4,7-dimethoxy-5-benzofurancarboxylic acid alkyl ester is prepared. This compound is then converted to known intermediates in the snythesis of khellin and analogs.

Abstract: @ An air/fuel induction system includes a pair of solenoid valves injecting fuel into an induction passage of a multicylinder engine. The valves supply fuel upstream of the inlet manifold to the engine and do not therefore direct fuel to specific cylinders. The solenoids (36, 36a) operate alternetely through pulses developed by drive units controlled by a microprocessor-based control unit (19). Each valve is independently timed by a respective timer-counter (44, 45) and valve operation overlaps in some circumstances. This allows smaller valves to be used and overcomes the problem of gusting at low speeds. The system may be applied to an LGP fuel system used as an additional fuel supply.

Abstract: Analogue/digital converter having a delay line arrangement which is provided along its length with a number of taps and both ends are supplied with auxiliary signals having the same signal shape from an auxiliary signal source. A phase difference between the two opposite auxiliary signals on the delay line arrangement is modulated in accordance with the analogue signal change by means of a controllable phase changing means under the control of the analogue signal to be converted. The two opposite auxiliary signals at the individual tapping points are examined to see whether they are equal or unequal by tap detectors connected to the individual taps. With this arrangement the quantisation pattern can be picked up at the outputs of all the tap detectors. <IMAGE>

Abstract: An electrical connector for electrically connecting terminal pins (23) of a circuit package to a circuitry of another circuit board having quasiterminal pins (34, 34') for elastically pre- bending pairs of spring arms (312,313) of contact elements (31,31') in the connector. The connector is provided with an insulator base member (32) for embracing the contact elements (31, 31'), and an insulator cover member (33) slidably overlying the base member (32). The base member (32) has recesses (321) for permitting the spring.arm pair (312, 313) to elastically bend. The covermember(33) has penetrating holes (331) for introducing the conductive pins (23) into the recesses (321). The quasi-terminal pins (34, 34') are attached to the cover member (33) adjacent to the penetrating holes (331), respectively, each of which is inserted between the spring arms (312, 313) and are in press-contact with them. Thus, the spring arms (312, 313) are pre-bentto facilitate an insertion of the terminal pin (23) into a space between spring arms (312, 313). The circuit package is adapted to the connector so that the terminal pins (23) are introduced into the recesses (321) through the penetrating holes (331). When the circuit package is slided along the base member(32), each of the terminal pins (23) is laterally shifted to be inserted into a space between the spring arms (312, 313) and then each of quasi-terminal pins (34,34') is shifted to go away from the spring arms (312, 313). Therefore, the terminal pins (23) are pinched between the spring arms (312, 313) to thereby be electrically connected to the contact elements (31, 31'). Preferably, each ofthe spring arms (312, 313) is provided with a guide leaf (318, 319) for guiding insertion of the quasi-terminal pin (34, 34') which is inserted thereinto.

Title: Stepping motors and drive circuits therefor
Inventor: HILL ROLAND JOHN
IPC: H02P8/12
Filed: 1984-03-13
Abstract: In a stepping motor having phase windings A, B etc. the current through the phase windings is switched by a drive circuit including switching transistors T1 A , Tie etc. in series with each individual phase winding. The transistors are controlled by a phase sequence logic circuit 14. A current flow characteristic is indicative of rotor position and is measured and used to operate the phase sequence logic circuit. The drive circuit may incorporate a chopper-type control operated through further transistors T2 A , T2 8  etc. also in series with each phase winding. The current flow characteristic that is measured may be current rise time, current decay time or chopping frequency. The current characteristic being monitored may be the characteristic in an energised winding or else in an unenergised winding at low current level. The drive circuit may alternatively provide a constant voltage power supply to the phase windings in sequence with current being repeatedly switched at a low level to an unenergised winding to monitor rotor position.

Abstract: A flash exposure optical imaging system is provided which includes a light housing a movable top and bottom surrace. The top surface (6) contains a document platen, the bottom surface (10) a fixed, wide-angle projection lens (12). These surfaces are vertically translated past a fixed, central housing wall (8) to vary the system conjugate in response to changes in magnification. In a preferred embodiment, a pair of elliptical cams (17) are rotated in response to position signals from a controller initiated by a magnification change. A pair of T-bars (16) and linkage machanisms (15) are associated with these cams and their motion provides simultaneous vertical motions to the top and bottom housing surfaces, respectively. During the vertical excursion of the floor assembly, an additional horizontal motion is imparted to the lens (12) so as to maintain correct corner registration of the image of the document at the image plane (18).

Abstract: A heat exchanger (31) cools at a programmed rate a predetermined area of skin. The rate at which the area of skin changes in response to temperature change of the heat ex changer and the rate the skin temperature returns to normal are then measured and compared to standard rates over a number of cycles Impaired peripheral blood flow is evident especially on subsequent cycles as vascular disease slows the rate of return to normal temperature of the skin. The heat exchanger has a cooling chamber (110) with one side of the chamber being a cooling surface (111) adjacent the skin. An injector (1301 is connected to a source of fluid (75) having a boding point at ambient pressure less than the temperature to which the skin is to be cooled. The injector injects fluid into the chamber and onto the side of the cooling surface opposite the skin to boil the fluid on the surface to cool the surface and the skin.

IPC: H01R12/58

Abstract: A compliant, press fit, electrical contact (10) includes a relief groove (34, 36) which forms an area of reduced cross sectional thickness to provide a stress concentration, and thus a controlled region of plastic flow (80, 82), to create a plastic-elastic hinge (78, 79). When the contact (10) is inserted into a plated through hole in a printed circuit board, the hinge (78, 79) elastically deforms until a predetermined push-in force is reached, at which time a controlled plastic flow begins. Once the point of plastic flow is reached, the amount of additional push in force required for additional deflection of the hinge (78, 79) is greatly reduced, so that smaller hole sizes may be accommodated with a relatively small additional push in force. However, the required minimum pull out force is maintained for the entire range of hole sizes, since elastic energy remains stored in the hinge (78, 79), even after plastic flow begins. The contact (10) is manufactured through a series of simple coining and punching operations, so that complex rounding and rolling operations are avoided.
