The invention relates to a device for clamping a safety belt to prevent it being unwound from a belt reel, the device consisting of a housing in which is provided a lever, one end of the lever being pivotably mounted in the housing, a clamping surface being provided on the lever intermediate its ends which co-operates with a clamping surface provided on the housing, the lever being resiliently urged to move about its pivot in a direction to separate the clamping surfaces. The belt is guided around the pivoted end of the lever, extends between the clamping surfaces and is guided around the free end of the lever, the resilient means applying a tension force to the belt. Movement of the lever against the force of the resilient means moving the clamping surface on the lever towards the clamping surface on the housing to clamp the belt therebetween.

A method and apparatus for drying wet granular and/or lumpy materials, employs a chamber having a material inlet, a material discharge outlet, an inlet for a heated drying fluid and a vapor outlet. A perforate sieve-type material support extends along a path between the material inlet and the material discharge outlet to provide communication between the drying fluid and vapor outlet through the material and a microwave generating and transmitting device is located above the material path to irradiate the material with microwave energy as a part of the drying energy supplied to the material.

The direct reduction of iron ore, e.g., in a shaft furnace, uses a pair of reducing-gas generating reformers which are alternately heated and functionally interchanged to produce the reducing gas. Downstream of each of the reformers is an air-preheating heat exchanger and between both reformers and the direct-reduction furnace there is provided a buffer heat exchanger. The combination reduces the fluctuations of the reducing-gas temperature at the inlet to the direct-reduction furnace and is able to maintain a reducing-gas temperature close to the desirable maximum for effective reduction.

A multi-phase frequency divider comprises first and second latches configured to receive a first input clock having a first frequency and a first phase, wherein the second latch receives the inverted first input clock. The first and second latches generate a plurality of output clocks each having a frequency that equals the first frequency divided by a predetermined divider ratio. The plurality of output clocks each have different phases staggered from the first phase. The frequency divider also comprises at least a first delay latch electrically connected between the first and second latches. The first delay latch is configured to generate, based on an output clock generated by the first latch and a second input clock at the first frequency and a second phase, two delayed output clocks. These two delayed output clocks have a frequency that equals the first frequency divided by the predetermined ratio with different staggered phases.

The present invention relates to ballast which have a high stability and a long service life and to a process for the production of ballast. These ballast are suitable for railway track laying and road construction and dike systems used for example in costal protection. These ballast comprise ballast stones and polyurethane foams based on a reaction mixture of selected polyisocyanates and selected compounds with isocyanate-reactive groups.

The invention relates to a tool, tool, in particular a screwing tool (1), comprising a handle (2), a working part (5) that is connected to the handle and that is used to open or close a threaded connection, and a display device (10) that displays a working value, for example a tightening torque of the threaded connection, wherein the display device (10) has at least two representations of the working value, in particular the tightening torque. In order to develop a generic tool in such a way that incorrect operation can be prevented with sufficient reliability, a covering device (17) is provided, which covers at least one working value and/or is designed in such a way that only one working value can be displayed in the display device (10).
摘要:
The invention relates to a method for controlling a dispensing system positionable in the interior of an automatic dishwasher, encompassing a cartridge filled with at least one preparation, a dispenser that is couplable to the cartridge, the dispenser encompassing at least a temperature sensor and a conductivity sensor, such that the temperature sensor and/or the conductivity sensor can be arranged in and/or on and/or outside the dispenser; and a delivery means for releasing a preparation from the cartridge into the interior of the automatic dishwasher.
摘要:
The present invention is a method for controlling a dispenser reversibly positioned in a dishwasher. The dispenser or dishwasher is configured with light transmission and receiving units. Light pulses are transmitted into the interior of the dishwasher and received by the receiving unit. The time difference (tI2−tI1) between the pulses is determined and that time difference is used to encode an information item or a portion of an information item. Such information items include a control signal, a measured value, an operating state of the automatic dishwasher and/or of the dispensing apparatus.
摘要:
A process for producing high resilience flexible polyurethane foams. The process includes forming a mixture of (a) isocyanate prepolymer, (b) polymeric compounds having isocyanate-reactive groups, (c) castor oil, (d) optionally chain-extending and/or crosslinking agents, (e) catalysts, (f) blowing agents, and optionally (g) additives, and reacting the mixture to form the flexible polyurethane foam. More than 5 wt % of (c) is used, based on the total weight of components (b) to (g), and (a) is obtained by mixing diphenylmethane diisocyanate (a1) and polyol 1 (a2) and also optionally further polyols, chain extenders and/or crosslinkers, where (a2) includes a polyalkylene oxide polyol having a hydroxyl number of 30 to 60, an average functionality of 2.3 to 3.2 and a propylene oxide fraction, based on the alkylene oxide content, of 70 to 100 wt %. A polyurethane foam obtained by the process, and the use of such a foam as an auto seat.
