Abstract: ABSTRACT          CELL-CONTAINER AND CELL-LID FOR ELECTRIC-ACCUMULATORS PARTICULARLY FOR THOSE MEANT FOR TRACTION          The cell-container, obtained by blow-forming, thus having a minor thickness, presents at the upper-rim a conformation in two steps(1) permitting the mating of the cell-lid to the cell-container remai= ning within unified overall-dimensions, as the welding-bead between the cell-lid and the cell-container forms itself on the inside in= stead of on the outside of the same. Furthermore, it becomes possi= ble to increase the welding-surface according to one's need if the cell-container is cut in correspondence with the flat-part of the step. The cell-container presents, furthermore, horizontal-recessings at various levels permitting the modular-cutting of the product ac-cording to unified measures.            The cell-lid's form is concave towards the exterior in order to fol= low the dilatations of the poles during the service-life of the bat= tery. The cell-lid is also furnished with a molded ring, which has a circular profile around the electrolyte's inlet thus avoiding the application of a gasket onto the top-cover.

Abstract: Abstract:          A capsule sealing machine comprising a rectifying unit for rectifying capsules that have been supplied from a hopper, to cause them to assume a predetermined posture.  A conveyance unit conveys the capsules from a transfer station, at which the rectified capsules are successively transferred thereto, towards a delivery station.  A liquid binder applicator applies a liquid binder, for example, gelatin solution, to the overlapping joint area between the cap and the body of each of the capsules to provide a tamper-resistant seal.  A drying unit dries the applied liquid binder.  The arrangement achieves a reduced processing time.

Abstract: COLOR IMAGE DISPLAY APPARATUS     ABSTRACT     In a color image display apparatus, a plurality of color corresponding memory planes forming an image memory, are simultaneously addressed by a common address from a CPU so as to either write image data on data busses respectively connected thereto, or read image data out on these data busses.  The image data to be written in the image memory are distributed to the data bus of each memory plane in the R/W circuit.  These image data are written in a memory plane or planes that are selected by first selecting means.  Reading is simultaneously performed in each memory plane, and the read image data are loaded in read registers that are provided for the respective memory planes.  The contents of a read register or registers among them that are selected by second selecting means are outputted to the CPU.

Abstract: FLUID INJECTION GAS TURBINE ENGINE              AND METHOD FOR OPERATING              ABSTRACT OF THE DISCLOSURE      A gas turbine including at least a compressor, a combustor, and a turbine is constructed to operate at a preferred thermal efficiency in predetermined compressor and turbine flow pressure ratios.  A fluid, such as steam, for example produced by waste heat and pressurized as water, and characterized as having a higher specific heat at constant pressure than effluent from the combustor is introduced into such effluent to provide a turbine operating medium of improved potential to transfer energy downstream of the combustor.  Such injection provides effective variable geometry to the system.  This injection system maintains such pressure flow ratios substantially independent of engine power output.

Abstract: Attorney's Docket No. 7560 CAN    INVENTORS:  PETER BOEGLI and J?RG BUSER            INVENTION:  CONTROL SYSTEM FOR DRIVING AND STEERING DRIVERLESS             TRANSPORT DEVICES     ASTRACT OF THE DISCLOSURE           Each transport device contains at least two drive wheels which are driven at individual speeds and which are pivotable by related steering angles .alpha. and .beta..   Identical servo-drive units are associated with the drive wheels and their mode of operation and mutual coupling is adapted by switch devices to the steering angle such that the speed is automatically adjusted through the entire angle range -90° ? .alpha., .beta. ? +90°.  At .alpha. = .beta. = 0° the leading servo-drive unit is rigidly guided by its speed regulation loop as a MASTER servo-drive unit and its armature current is supplied as a reference magnitude to the armature current regulation loop of the trailing servo-drive unit which is operated as a SLAVE servo-drive unit.  At .alpha. = .beta. = ?90° the two servo-drive units operate as independent MASTER servo-drive units and their speed regulation loops receive related reference speed signals from related microcomputers.  At -90° < .alpha., .beta. < +90° the MASTER/SLAVE     configuration  and  the  MASTER/MASTER  configuration  are selectively used depending on the operating conditions and the travel durations.  The optimum adaption of the servo-drive units to the steering angles and the limitation of the speed to the maximum speed which corresponds to optimum efficiency, insure precise track guidance, improved maneuverability and minimum current consumption.
