摘要:
Measuring module for the measurement of an object (6), having a measuring chamber (4), with a contact element (5a, 5b), wherein the object to be measured (6) is thermally connected to a first contact surface (9a) of the contact element (5a, 5b), and having a cold head (1b, 2b, 2c) that can be thermally connected to a second contact surface (9b) of the contact element (5a, 5b), wherein the contact element (5a, 5b) consists of material with high thermal conductivity, characterized in that the cryo-refrigerator (1a, 2a) together with the cold head is housed in a refrigerating chamber (3) that is physically separated from the measuring chamber (4) and can be evacuated separately from the latter, and the contact element (5a, 5b) is thermally insulated from the outside wall of the measuring module, is part of a separating wall between the measuring chamber (4) and the refrigerating chamber (3), and makes a local thermal connection between the measuring chamber (4) and the refrigerating chamber (3), and with a contacting mechanism to vary heat flow in the hermetically sealed condition of the measuring module. With such a measuring module, cooling times and heating times of the object to be measured can be greatly reduced.

An anti-twist device retains an actuating motor (10), which is placed in a force-fitting and/or form-fitting manner onto the projecting driveshaft (22) of a pivotable shut-off flap (62) of a gas transport tube (34), in particular of an HVAC tube or flue gas tube for a building, in a longitudinally moveable manner. Arranged at an adjustable axial distance (a) from the driveshaft (22) is at least one clamp (36) which secures the actuating motor (10). The parallel limbs (46) of the preferably substantially U-shaped clamp (36) are of resilient design, wherein in each case one end-side, inwardly projecting latching lug (48) is formed for holding down the actuating motor (10).

The invention relates to a device (10) for controlling airflow (A) in a ventilation pipe (12) comprising one or several air throttle (32) which are synchronously actuated and prevent air flowing (A) in the air pipe in the closed position thereof. The ventilation pipe (12) is provided with a longitudinally extending fixing bar (16) which is arranged on a symmetry plane and provided with the pivot bearing (30) of an axis (28) for driving the air throttle(s) (32) and means (50, 52) for transmitting a force and/or torque to the drive axis (28) connected to the air throttle(s) (32). Said fixing bar (16) provided with different air throttles (12) is usable for the ventilation pipes having different cross sections and forms, an angle (β), preferably, ranging from 15° to 90°, with a longitudinal axis (L) or with a wall (18) of said ventilation pipe (12).

The present invention generally relates to shared-memory multiprocessor systems, such as IBM ESA/390 or RS/6000 systems, and deals more particularly with a method and system for sharing a second-level translation lookaside buffer (TLB 2) between several CPUs (30a, . . . 30d) for improving the performance and reducing the chip area required to buffer the results of virtual-to-absolute address translations. The inventive TLB2 organization comprises several small arrays (32a, . . . 32d) dedicated to particular CPUs, providing an interface to a major array (21), which is shared between the CPUs. The dedicated arrays 32a, . . . 32d) are required to fulfill the architected constraints and link several CPUs to the commonly used shared array (21).
摘要:
An apparatus for controlling a warp tensioner of a weaving machine. The apparatus contains a spring member that is in working connection with the warp tensioner and a control system that has a container communicating via a 2/2 way valve with the spring member in order to vary the spring stiffness of the spring member and the position of the warp tensioner from a terminal at the side where the weaver stands by increasing and decreasing the effective volume of the spring member.
摘要:
A control curve is calculated for controlling the yarn tension including warp and weft yarn tensions in a weaving loom by comparing a previously determined yarn tension curve with a desired value for the yarn tension curve. The control characteristic is optimized by continuous iteration. A further optimization of the yarn tension curve takes place by taking account of variable parameters in the yarn tension curve, for example yarn breakage analysis, beat-up force of the reed, and/or shed change. The control device for performing the method can be implemented with conventional logic. The method automatically carries out in an advantageous manner for weft and warp yarns a matching to the optimum yarn tension as a function of time on the basis of preselected parameter values.

Disclosed is an HVAC (heating, ventilation and air-conditioning) system which comprises a fluid flow duct (1), a fluid flow valve (7) which is arranged therein and has a valve body (5) in the fluid flow duct (1) and a valve motor (15) which moves the valve body (5), a control circuit for activating the valve motor, a sensor (8) in the fluid flow duct (1) and an evaluation module for evaluating signals of the sensor. To produce an automated functional control, the following procedure is adopted: a first actuation signal is preset for the valve motor by the control circuit, and the actuation signal corresponds to a first setpoint position of the valve body (5), registration of a first signal of the sensor (8) by the evaluation module, and determination of a functional diagnosis of the fluid flow valve on the basis of the first signal of the sensor.
