Latch systems for a drive cage assembly are disclosed. In an exemplary embodiment, the latch system may be operated by moving a hinge bracket in a first direction to slide at least one latch on the hinge bracket into an open position. Then receiving a peripheral device in the drive cage assembly in either a tower orientation or a rack orientation when the at least one latch is in the open position. Then moving the hinge bracket in a second direction to slide the at least one latch into a closed position and secure the peripheral device in the drive cage assembly.

Stable, concentrated herbicide preparation comprising at least one herbicide with at least one amino group, at least one carboxylic acid group and at least one phosphor containing acid group suspended in finegrained form in a liquid phase, and at least 5% a by weight of a dissolved electrolyte; a process for producing said herbicide preparation and an activating additive (adjuvant) for combination with said herbicide preparation. Preferred suspensions comprise the herbicides glyphosate and glufosinate and the electrolyte ammonium sulphate, acting synergistically. It has not hitherto been possible to incorporate high concentrations of synergistic electrolytes in liquid concentrates of said herbicides.

The present invention relates briefly to an arrangement for hoisting devices to keep a cable (10) substantially vertically stretched between a derrick or the like and a hoisting device, e.g. a derrick bridle (1), so that the cable will not be able to be depositioned by gusts and other factors. The arrangement includes a set of brackets (12) stretched between and glidably fixed to two opposed hoisting cords (2a, 4a), each bracket (12) being equipped with a ring (13) approximately center, through which ring the cable (10) runs with an increasing inner diameter for each ring (13) from the top downwards. To the cable (10) are fastened a set of elements (14) spaced apart with increasing diameter for each element from the top downwards for each inner diameter of the rings (13) so that each element (14) one by one is restricted to pass a corresponding ring (13) and thereby each hoists one by one a bracket (12) holding the cable (10).

The release of a moulded concrete body from the mould can be improved by applying, to the mould, an effective amount of a concrete release composition in the form of an oil-in-water emulsion in which the oily phase is at least one of the following: a mineral oil with a content of aromatics of at most 9%, a vegetable oil and one or more oily esters of aliphatic carboxylic acids with mono- or dihydric alcohols and having a melting point of at the most 35.degree. C., the total number of carbon atoms in the esters being 8-46, and comprising one or more non-ionic surfactants in an amount of 0.5-20% by weight and one or more anionic surfactants in an amount of 1-100%, based on the non-ionic surfactant. The emulsion may also comprise cationic surfactants, anti-freeze, stabilizers, corrosion inhibitors, etc. The oily esters of aliphatic carboxylic acids with mono- or dihydric alcohols may also be used in non-emulsified form.

A windmill is provided with a yawing device which includes two or more gear motors disposed about the periphery of a stationary tower toothed rim. Each gear motor has a driving wheel attached at an end thereof for engaging the toothed rim. By applying a suitable current to the gear motors, in equal and opposite directions, the mill can be held at an optimum position, relative to the wind, at a low power consumption. The use of multiple motors also provides optimum reliability with smooth and even yawing action.

A safety mat for protection against erosion and/or undermining consisting of a number of parallel tubular members containing a filling material and being interconnected by cross-binding ribbons placed at right angles to the tubular members. As filling material is used a granulated material of an average density of at least 1.6 Kg/dm.sup.3, and the tubular members have a degree of filling of substantially 75%. Using a relatively heavy filling material that is introduced relatively loosely a mat is obtained having great flexibility, being able, therefore, to lie close up against even a domed bottom.
摘要:
A yawing system for a wind mill consists of two yawing motors (9, 11) acting on a toothed rim of the yawing bearing. On each its drive shaft (21) the motors (9, 11) are provided with a free wheel (23) and an electromagnetic friction brake (25). The free wheel devices (23) are directed opposite each other. A control system operates in a passive state in such a manner that the motors give opposite and relative to the braking moment of the brake (25) of a second motor smaller torque thereby avoiding dead clearance between drive wheel (15) and toothed rim (17) while at the same time keeping the generator housing (5) of the mill at rest. In the active state of the control system both brakes (25) are disengaged and both motors give a higher torque in the same direction. The system acts as a shock absorber by loads exceeding the fixed slip moment of the friction brake (25).

Stabilized liquid herbicidal compositions containing at least one substituted phenyl carbamate of the general formula I ##STR1## in which R.sup.1 represents a C.sub.1 -C.sub.6 alkyl group, a C.sub.3 -C.sub.6 cycloalkyl group or an aryl group, which aryl group may be substituted by a halogen atom and/or a C.sub.1 -C.sub.6 alkyl group and/or a trifluoromethyl group, and R.sup.2 represents a C.sub.1 -C.sub.6 alkyl, C.sub.2 -C.sub.6 alkenyl or C.sub.2 -C.sub.6 alkynyl group that may be substituted by a terminal halogen atom, and optionally at least one herbicidally active compound selected from the group consisting of 5-amino-4-chloro-2-phenyl-3(2H)pyridazinone, 2-ethoxy-2,3-dihydro-3,3-dimethylbenzofuran-5-yl methanesulphonate, and 4-amino-4,5-dihydro-3-methyl-6-phenyl-1,2,4-triazin-5-one are prepared by dispersing the compound(s) in finely ground state in a liquid phase which comprises one or more oily components and one or more surfactants and which is able to form an oil-in-water emulsion or a microemulsion when mixed with water.
摘要:
To mix a gas with a mass flowing continuously through a conduit, the gas is caused to flow from a pressurized gas supply into the conduit by way of a nozzle in which the gas expands at a critical pressure ratio; and the pressure of the gas flowing from the nozzle is increased before the gas is introduced into the flowing mass.
摘要:
A method for detecting an insert object in an injection-molded part pertains to an insert object that is fixedly connected to the injection-molded part during the injection molding by the insert object being placed in a cavity, which is surrounded by a mold wall of a mold, before the beginning of the injection-molding cycle. The mold wall includes at least one temperature or pressure sensor, which records and analyzes at least one measured value at at least one point in time during an injection-molding cycle. On the basis of the analysis, it is established whether an insert object was present at a specific location in the cavity during the injection-molding cycle. Finally, after it is ejected, the injection-molded part is sorted as an accepted part or a rejected part on the basis of the analysis of the measured value.
