Abstract: A modular valve system (10) to be mounted to a support, in particular a support in an electric control cabinet, comprises at least two individual valve modules (12) which can be fluidly connected to each other and to which at least one control valve unit (16) can be coupled in each case. The modular valve system (10) includes a process fluid section (90) comprising process fluid lines (78) through which a process fluid can flow, a control fluid section (32) comprising control fluid lines in at least some of the valve modules (12) through which a control fluid can flow, and a membrane (80) which is shared by at least some of the valve modules (12) and designed for controlling the process fluid in the process fluid section (90) while forming membrane valves (50) and for sealing off the control fluid section.

Abstract: There is described a valve island base module (12, 14) with at least one valve module receptacle (25a-25h), which comprises means for the attachment of a plurality of valve modules (18a-18h) each including at least one electrically actuatable valve on the valve island base module (12, 14). In addition, the valve island base module (12, 14) has a fluidic and an electrical valve module connection (36a-36h) for the power supply of the valve modules (18a-18h) with electric current. A power supply line (30) is electrically connected with the electrical valve module connections (36a-36h). By means of a safety interface (26, 28) accessible from outside, the power supply of at least one electrical valve module connection (36a-36h) can selectively be interrupted. In addition, there is described a valve island (10) with at least one valve island base module (12, 14) and at least one valve module (18a-18h).

Abstract: A driven disc assembly is provided. The backing plates have right angle depression sections that surround mounting holes of a clutch disc. The thickness of the backing plates are enlarged from their normal thickness causing a top surface of the backing plates to axially clear heads of conventional rivets. The thickness of the friction buttons on the backing plates can then be reduced to their minimal effective use thickness.

Abstract: A cooling arrangement for cooling weld caps of a welding device includes a local cooling pipe having a feed portion through which coolant can flow to the weld caps, and a return portion through which coolant can flow away from the weld caps. The cooling arrangement has at least one sensor and at least one actuator arranged at the cooling pipe. A check device is connected to the sensor and the actuator. The check device is arranged in an immediate vicinity of the sensor and/or the actuator and/or the local cooling pipe, and is adapted to receive measured values of the sensor and to check, based on pre-established criteria, whether the measured values are within a predefined desired range. In response to a negative check result, the check device can drive the actuator in a predetermined manner such that the cooling arrangement is placed in a safe condition.

Abstract: A highly precise and extremely compact metering unit for fluid media has a pump, two valves, and a fluid communication base with two ports, pump and valve channels, and a pump chamber. The pump is mounted on the pump chamber. The pump channels communicate with the pump chamber and the valves. The valve channels communicate with the valves and the ports. The pump and the two valves are arranged one beside the other on the same side of the fluid communication base.

Abstract: A flexible tri-fold garment bag has an elongate integral body with a front and rear flexible panel and a peripheral side flexible panels connected to the front and rear flexible panel along the mutual peripherial edges thereof. A top flexible strap handle is connected at the top of the bag to the rear panel, and a mid flexible strap handle is connected to the rear panel at the upper end of a lower one-third of the bag body. The top handle is longer the mid handle so that the thickness of the bag body when filled with garments can be accomodated.

Abstract: Continuous hydrolysis to produce sugars is effected by cyclically immersing a solid, divided lignocellulosic material in a bath of concentrated hydrochloric acid and draining the material between successive immersions so as to dissolve the produced sugars, until the sugar concentration of the acid in the bath has attained a desired value.The solid material and the liquid acid are delivered to a tubular horizontal rotary reactor arranged to provide a bath of the acid, to produce a rotating movement for cyclical immersion of the solid material in the bath of acid and longitudinally displace the solid material undergoing hydrolysis together with the acid of the bath and to continuously discharge solid residue and acid containing dissolved sugars due to overflow by gravity at an outlet end of the reactor.

Abstract: A fragmented material is dissolved continuously by impregnation and immersion into a solvent bath in which said material is subjected to a moderate mixing movement allowing it to be kept within the interior of said bath to undergo dissolution therein until formation of fine residual particles of insoluble material which are maintained in suspension by this movement, the whole being removed continuously by a controlled overflow of the bath. This process is applied to cellulose contained in various lignocellulosic materials, which is dissolved continuously by immersion of the previously impregnated material into a bath of hydrochloric acid through which hydrogen chloride gas is caused to bubble, to effect complete dissolution of the cellulose and suspension of the fine insoluble residual lignin particles.
