Abstract: A mold for the continuous casting of metal to a sheet-like strand is provided with a casting passage (4) having a slot-shaped outlet end (6). The inlet end (5) of the casting passage is considerably wider, and has a much larger area, than the outlet end (6). This facilitates pouring of molten metal into the mold and permits the use of casting techniques such as shrouding which enhance the continuous casting process and/or the quality of the strand. The cross-sectional area of the casting passage (4) decreases progressively from the area at the inlet end (5) to that at the outlet end (6) over at least a portion of the length of the mold (1). The perimeter of the casting passage, however, remains at least approximately constant as the area decreases. This enables the strand to be drawn through the mold (1) without difficulty. A continuous casting method involves pouring molten metal into a casting passage (4), and reducing the cross-sectional area of the cast strand between upstream and downstream locations of the casting passage (4) while maintaining the perimeter of the strand at least approximately constant.

Abstract: According to the present invention, in the first instance, new aminopolyols, which can be obtained from the disaccharides isomaltose, isomaltulose and  alpha -D-glucopyranosyl (1->1)-D-fructose, are prepared. These compounds, designated as isomaltamines and having the formulae:    <IMAGE>  (I)   <IMAGE> (II) <IMAGE> (III)  as well as mixtures of the same, are produced by the reductive amination of the aforementioned saccharides by means of ammonia or hydrazine compounds in the presence of catalysts, such as Raney nickel, and hydrogen, or by means of complex metallic hydrides, such as sodium borohydride, in solution or suspension. The invention relates, furthermore, to the N-acyl derivatives of the individual isomaltamines or their mixtures as well as to the production of the N-acylates by a selective N-acylation. Depending upon the nature of the acyl radical, these acylates can be used for example, as surfactants or (similarly to N-acrylamide) for the production of polymers.

Title: Raster scan digital display system
Inventor: MOREL JEANNE ELLEN
IPC: G09G1/28
Filed: 1987-09-08
Abstract: An all points addressable raster scan graphics display system is operable in two modes. In the first mode, data is extracted from a refresh store, serialised, modified, and applied to a display device at a first frequency. In the second mode, data is extracted from the refresh store, serialised and partially modified at said first frequency, but it is then further modified and passed to the display device at an even sub harmonic, for example half, of the first frequency. The further modification includes concatenation of successive groups of display data bits. Accordingly, with the raster scan device operating at a constant scan velocity, the first mode provides a high picture element definition but relatively low colour definition display, and the second mode provides a display with an even submultiple, for example half, the picture element definition but considerably greater colour definition.

Abstract: An all-fiber mode selector comprises a single-mode optical fiber (100) and a double-mode optical fiber (110), each having a facing surface (144, 154) formed on one side of the cladding. The facing surfaces (144, 154) are juxtaposed in close facing relationship. The fibers are selected so that an optical signal propagating in the LP 11  propagation mode of the double-mode optical fiber (110) propagates at substantially the same phase velocity as an optical signal propagating in the LP 01  propagation mode of the single-mode optical fiber (100). The evanescent fields of the two fibers interact to couple optical energy from the LP "  mode of the double-mode optical fiber (110) to the LP OI  mode of the single-mode optical fiber (100) and vice versa.

Abstract: ASotor-driven power steering system for a vehicle is disclosed which can be switched or transferred from power steering into manual steering or vice versa in an extremely smooth manner without causing any abrupt change in steering torque and hence unsure feelings on the part of the operator. The power steering system comprises: a torque sensor (3) for detecting steering force imparted to the steering wheel by an operator; a vehicle-speed sensor (10) for detecting the vehicle speed; a motor (13) adapted to be energized by a source of electric power (11) for power assisting the steering wheel (1); an electromagnetic switching clutch (16) adapted to be switched off for interrupting the transmission of the power-assisting force from the motor (13) toward the steerable road wheels when the vehicle speed increases above a prescribed level, and switched on for establishing the transmission of the powersteering force when the vehicle speed decreases below the prescribed level; and a control unit (9) adapted to receive output signals from the torque sensor (3) and the vehicle-speed sensor (10) for controlling the operations of the motor and the clutch in a manner such that the power assisting force transmitted from the motor to the steerable road wheels is controlled in accordance with the travelling speed of the vehicle and the steering torque imparted to the steering wheel (1) by the operator. The current supplied from the source of electric power (11) to the motor (13) is gradually decreased to reduce the power-assisting force transmitted from the motor to the steerable road wheels as the vehicle speed increases before the clutch is switched off, and gradually increased to increase the power-assisting force as the vehicle speed decreases after the clutch (16) is switched on. The current for the motor may be controlled in dependence upon coefficients which are stored in memories (109c and 109d).

Abstract: The storage cell comprises a CMOS latch having a first CMOS inverter (P1, N1) and a second CMOS inverter (P2, N2) which have their respective storage nodes (A, B) interconnected by cross-coupling connections which each include a gated polysilicon resistor (R1, R2). The respective storage nodes (A, B) of the cell are connected through word line transfer devices (NA, NB) to bit lines (BL, BLʹ) which serve to both write in and read out the state of the cell. The control gates of the transfer devices are also connected to the control gates (32, 32ʹ) of the respective gated polysilicon resistors (R1, R2) in the cross-coupled connections for the cell. In normal operation, when the word line transfer devices (NA, NB) are not conductive, the gated polysilicon resistors (R1, R2) are also not conductive. When it is desired to write information into the cell during normal conditions, when the word line transfer devices (NA, NB) are made conductive, the gated polysilicon resistors (R1, R2) are also made conductive, thereby offering a minimum resistance to charge which is to be transferred between the respective storage nodes (A, B) of the cell. However, during a single event upset condition, when one or more of the sensitive regions of the cell undergo an abrupt charge transfer due to the presence of cosmic rays or other ionizing radiation phenomena, since the gated polysilicon resistors (R1, R2) are in their high resistance state, they impede the flow of any charges between the respective storage nodes (A, B) of the cell. In this manner, after the single event   upset has dissipated, the cell will have retained its original stored binary state. Thus, an enhanced resistance to single event upset conditions is provided by the invention while not imposing significant reductions in the speed of operation during normal conditions.

Abstract: An air spring (10) formed by a pair of spaced end members and an intervening tubular elastomeric sleeve (12) forms a fluid pressure chamber (18) therebetween for mounting between spaced portions (15, 16) preferably of a vehicle to provide damping and to absorb road shock on the vehicle. Each of the end members (15, 10) is provided with a surface formed with a series of convex projections and concave intervening areas which align with similarly shaped projections and concave areas on an adjacent snap ring. The snap rings compress the ends of the tubular sleeve against the corresponding end cap surfaces to provide a secure clamping engagement therewith. The various projections and surfaces form at least two radially spaced pinch areas (42, 44) on each of the end members and an intervening expansion area (50) in combination with a squeeze area (48) and subsequent terminal expansion area which ensures a change of direction of the reinforcement cords within the sleeve ends to securely clamp the sleeve ends therebetween. The expansion areas permit the elastomeric material of the sleeve to expand on both sides of the pinch areas. The combination of the pinch areas with adjacent expansion areas and squeeze areas provide for a secure end clamp and seal for the tubular sleeve without requiring any internal bead reinforcement.

Abstract: A three-dimensional optical scanning vision system capable of producing high-resolution images in real-time includes an optical source (100) for pro­ducing a source light beam. The source light beam is directed to a beam splitter (104) which splits it into a local oscillator beam and a signal beam. The local oscillator beam is directed toward a photo­detector (106), while the signal light beam is directed toward a target (112). Light reflected from the tar­get (112) is received by the beam splitter (104) and directed toward a retroreflector (118) which returns the beam to the beam splitter (104) interface. Quarter wave plates (110,116) and the retroreflector (118) insure that the return light beam and the local oscil­lator beam are collimated and have the same polariza­tion state. Mixing the local oscillator beam and the return light beam occurs at the beam splitter (104) interface, thus providing coherent optical detection by the photodetector (106). The photodetector thus provides an output signal providing a high degree of information about the target. The system also includes scanner optics (2) to scan the signal light beam across the target. A processor (20) is also included for outputting a three-dimensional image of the target, and for controlling the scanner optics (2).
