Abstract:
A process for checking the tablet parameters weight, height and hardness by weighing and measurement, and to a device for carrying out the process as an individual device and preferably as a rotary tabletting press for permanently complying with preset tablet parameters. A process and a device for rapid, reliable, reproducible, and distortion-proof checking of optionally all parameters or selected parameters on one tablet and the overall checking of the weight on a plurality of tablets are guaranteed. This is accomplished so as to carry out individual and/or overall checks with a receiving container (1) provided for tablets (2), and the receiving container (1) is connected to stations (3, 10, 11) for the optional determination of the weight, the height, and the hardness of a single tablet (2), and from the receiving container, an individual tablet 2 and/or a plurality of tablets (2) are fed fully automatically to and removed from the individual stations (3, 10, 11) for determining the tablet weight.
Abstract:
According to an illustrative example of the present invention, a gas spring comprises a pressure tube, a piston rod and a piston connected with the piston rod within the pressure tube. The piston divides the pressure tube into two working spaces, the two working spaces are connected by a control flow passage. A control valve body is allocated to the control valve passage and is controlled through a bore of the piston rod. The control valve body contains an excess pressure flow passage. An excess pressure valve member is provided within the excess pressure flow passage and biased toward an excess pressure valve seat of said control valve body.
Abstract:
In cryogenic applications a compression device circulates a fluid, such as helium, in a closed cooling circuit. The compression device includes at least one compressor, preferably a helical compressor, with a bypass valve connected in parallel thereto, which serves to decompress the compressed fluid. The suction pressure is measured with a pressure measuring device and is supplied to a control device, which controls the position of a powered valve spool of the compressor and also the position of the bypass valve. In order to achieve a high control performance with small bypass losses for load cases which are hard to predetermine, the positions of bypass valve and power valve spool are adjusted so that a fluid flow flows as a control reserve through the bypass valve and is on the order of a fraction of the total fluid flow.
Abstract:
A steering column of a motor vehicle is composed of two telescopically and torque transmittingly interengaging steering column tubes. These tubes are mounted in bearings. A steering wheel is allocated to a first steering column tube. The other steering column tube is connected with a steering gear box. A cylinder piston device is provided within at least one of the two steering column tubes. This cylinder piston device can be locked in a plurality of positions, such as to define a plurality of variable lengths of the steering column.
Abstract:
In a hydraulically blockable gas spring a hydraulic chamber and a gas chamber are provided one behind the other within a cylinder. The chambers are separated from each other by a separating wall. A first section of a piston rod is sealingly guided through one end of the hydraulic fluid chamber and is connected with a separating piston within the hydraulic fluid chamber. The separating piston divides the hydraulic fluid chambers into two hydraulic fluid compartments. The fluid compartments are interconnected by a hydraulic flow path. The hydraulic flow path can be selectively opened and closed by a valve. A second piston rod section extends from the separating piston through the separating wall and sealingly enters into the gas chamber. The pressurized gas within the gas chamber provides a biasing action onto the second piston rod section. The hydraulic chamber is completely filled with a hydraulic fluid. When the valve is closed, the separating piston and the piston rod sections are positively blocked in both axial directions. When the valve is open, the separating piston and the piston rod sections can be moved as a unit and are subject to the biasing action of the pressurized gas.
Abstract:
The invention relates to an in-motion scale, in particular, to a conveyor scale with a conveyor belt, with a load cell (9) and a conveying device (5) for goods to be weighed, in particular, packaged goods, for feeding the goods to and leading them away and from the load cell (9), and with a control device (11) for controlling the functions of the in-motion scale. According to the invention, the control device (11) can be changed over to a cleaning mode in which the functions of the in-motion scale (1) are controlled according to a specified cleaning-mode functional model so that danger to operating personnel and/or damage to the in-motion scale (1) is reduced or eliminated.

Abstract:
In the case of an item of seating furniture, particularly an office chair, comprising at least one seat adjusting device, for example for adjusting the height of the seat, with a spring element engaging the two parts of the seat which are to be adjusted in respect of each other, particularly a pressurized fluid filled spring, and with a locking device for the separable fixing of the two seat parts in whatever is the desired and selected adjusted position, the use of an electrical actuating element for the locking device is proposed, which is connected to a manually operable control means for the at least one seat adjustment, this allowing simplified operation with minimal structural expenditure.
Abstract:
According to an illustrative example of the invention, a gas spring comprises a cylinder and a piston rod. The piston rod is axially movable with respect to the cylinder and has a fastening eye mounted on the outer end of the piston rod. A tubular protection member surrounds an end portion of the cylinder adjacent to the end of the cylinder which is passed by the piston rod. The other end of the protection tube surrounds a holding disk fixed to the piston rod adjacent to the fastening eye. The protection tube and the piston rod define an air space therebetween. The air space is substantially tight against a liquid treating agent, such as a lacquer. On the other hand, the air space is in air flow connection with the surrounding atmosphere so that in response to axial movement of the piston rod with respect to the cylinder, excesssive pressure within the air space is prevented.
