Abstract: The present invention relates to liquid herbicidal agents in the form of emulsifiable concentrates (EC) or concentrated emulsion (EW), characterised in that they contain, besides 1 - 40% by weight of the active substance diclofop-methyl (I), fenoxaprop-ethyl (II) or its optically active isomer (D+) fenoxaprop-P-ethyl (III), 0.5 - 30% by weight of (C10-C18) fatty alcohol polyglycol ethers or (C8- C9)alkylphenyl polyglycol ethers which are 6 to 10 times ethoxylated as surfactants, and, in the case of EC formulations, 0.5 - 7% by weight of calcium (C18-C14)alkylbenzenesulphonate and, in the case of EW formulations, 0.5 - 7% by weight of an ethylene oxide/propylene oxide/ethylene oxide block copolymer which is phosphorylated in the alpha- and omega-position or a salt thereof as dispersant, besides the customary formulation components. Compared with the known active substance formulations, these agents have markedly increased activities and improved miscibility properties with water and with commercially available preparations containing other active substances.

Abstract: A passive seat belt control apparatus includes a retractor for housing part of a seat belt.  The retrac-tor includes an arrangement for sensing acceleration and deceleration of a vehicle door and the speed at which the seat belt is pulled out from the retractor, and a mechanism for locking the seat belt.  A solenoid operates to cancel the function of the retractor, and a door switch detects opening and closing of the vehicle door.  A main control unit actuates the solenoid when the door switch detects that the door is open, and the main control unit includes an arrangement for con-tinuously maintaining the solenoid operative for a pre-determined time whenever the door switch detects that the door is closed after it has previously detected that the door is open.

Abstract: Disclosed are the N, N'-(1-oxo-1,2-ethanediyl)-bisaspartates, methods for their preparation (including an unexpected preparation from glyoxal bisulfite and aspartic acid in concentrated aqueous alkaline media) and useful compositions containing the same; illustrative are general-purpose sequestrant compositions, chelating agent compositions for transition metals such as iron, manganese and copper,  general-purpose laundry detergent compositions and detergent compositions comprising perborate bleach, a bleach activator and, as a bleach stabilizer/performance enhancer, the novel bisaspartates.  These unique nonphosphorus compounds are useful  at low levels and differ from traditional -N-C-C-N- chelating agents such as ethylenediaminetetraacetates by the presence of one amino- and one amido- functional group which it is believed will provide additional advantages, such as improved biodegradation.

Title: Novel alkaline pullulanase y having .alpha.-amylase activity, microorganism producing the same, and process for producing the same
Inventor: ARA KATSUTOSHI
IPC: C12R1/07
Filed: 1990-09-10
Abstract: A novel alkaline pullulanase Y having .alpha.-amylase activity; a microorganism producing said alkaline pullulanase Y; and a process for producing said alkaline pullulanase Y are disclosed.  The alkaline pullulanase Y having .alpha.-amylase activity has its optimum pH at a higher alkaline range than conventional alkaline pullulanases and exhibits excellent stability over a wide pH range.          Further, the alkaline pullulanase Y has strong resistance to almost all detergent components such as surfactants, chelating agents, proteases for detergents, and the like.          Thus the alkaline pullulanase Y can advantageously be used as a detergent component.

Title: Stable oral composition of zinc
Inventor: SCHIRALDI MICHAEL T
IPC: C08L67/02
Filed: 1990-11-05
Abstract: ABSTRACT OF THE DISCLOSURE         A stable and clear aqueous solution of zinc salt useful as a mouthrinse and a gel dentifrice.  In a preferred embodiment the aqueous solution comprises zinc chloride codissolved with a complexing agent of sodium gluconate, in a naturally derived anionic polymer of sodium carboxymethyl-cellulose.  This solution is advantageous because it maintains clarity and chemical stability in temperatures of from about 4 to about 50°C and may be alcohol-free.  The anionic polymer acts as a buffer to provide a solution with a pH in a desirable range of from about 5.7 to about 6.5, which limits astringency and tartness.

Abstract: A process for the continuous welding of railway track sections (3) during installation, in which a set of wagons, especially equipped for the purpose (5-5'), and made up of one or more wagons (5, 5') with an extra-low load plane, is introduced into the line of operation, between the wagons (1) carrying the new track sections (3) and the new cross beams (2) and the operating machine installing said beams and sections. The operations aligning, levelling and butting successive track sections (3) take place on said set of wagons (5-5'), as does the welding of said sections, which involves the movement of welding machines (15-17) on a trolley (8) along the set of wagons (5-5'). The welding operations are carried out during a run of the trolley (8) along with the welding machines (15-17) in the opposite direction to that of the advancing line of operation. This welding run is then compensated by a return run of the trolley (8) and welding machines (15-17) in the same direction as the line of operation. In this way, all the welding takes place on the operation line itself, installation being carried out by the corresponding operating machine on tracks which are now continuous.

Abstract: In this bogie (1) the static and dynamic forces are absorbed by the frame (5). In designing the body unit fitted on the frame (5), therefore, only the unit's own weight and the passenger load are significant, thus facilitating the use of extremely lightly-built vehicle bodies. The bogie (1) consists of single-wheel drive units (2), a longeron (3) interconnecting them, on each long side of a drive (4), the frames (5) bearing the end unit (9) and a drive control (6) for turning the single-wheel drive units (2) horizontally depending on the curves. A wheelless central unit (10) is supported on each short side on the bogie (1) via a joint (8). A ush-pull device (7) engages with the short side opposite the joint (8). There are no lobbies inside the vehicle which is thus freely accessible. In the region of bogie there are recesses in the form of wheel-boxes in which certain parts of the bogie (1) are arranged.

IPC: G10L17/26
Filed: 1991-05-02
Abstract: Apparatus and method for recognizing a signal, receives the signal and samples it at a plurality of sampling points to produce a plurality of signal values. A statistical moment of the signal is calculated using the signal values according to the formula:    where: N = the number of sampling points: n = 1 < n < N      X = the signal value of the signal at the sampling point: µ = a mean of the signal values: .sigma. a standard deviation of the signal values: and k = an integer greater than 1.        The calculated statistical moment is then compared with a plurality of stored signal identifications and the received signal is recognized as similar to one of the stored signal identifications. Preferably, the calculated statistical moment is used to create a feature vector which is quantized, and a weighted sum of the quantized feature vector is used to assess a memory which stores the signal identifications.

A central portion is located intermediate the pair of tread portions and includes a surface defining a circumferentially extending groove.  A central member has a substantially annular configuration in an unloaded condition.  The central member has an outer diameter greater than the outer diameter of either of the rim beads and less than the inner diameter of the annular reinforcing member.  The central member is located radially inward of the groove in the central portion and is deflectable from the annular configuration as the tire rotates through a footprint.     dlh/1613 - 6/18/90
