Abstract: A cantilever parasol has a mast, two main arms proceeding laterally from the mast and coupled to each other in a scissors-type manner, and a linkage of bars for supporting a cover. A first main arm extends from an upper mast bearing through a slit in the cover to a vertical arm of the linkage of bars. At least one sealing structure is provided for sealing the slit in the cover.

Abstract: A ground-anchored umbrella stand comprises a base unit which is to be anchored in the ground and includes a soil sleeve extending into the soil. A pole mounting unit, in which the pole is inserted, is fastened to the base unit so as to be able to tilt relative to the base unit in all directions in space. An adjustment and locking mechanism between the base unit and the pole mounting unit allows tilting and aligning the pole mounting unit in all directions.

Abstract: The blades (1, 11, 12, 13, 1n) of a turbine or compressor are fastened into a groove (8) on the rotor (6) or stator of the turbine or compressor by blade roots (4), there being no play or a prestress prevailing between the root plate (3) and/or the blade root (4), and adjacent blades (1, 11, 12, 13, 1n) thereby being supported relative to one another with respect to torsional moments (12) and not or only slightly on the rotor (6) or stator. This is possible, for example, by incorporating a bevel (9).

Abstract: A table for the transfer of fragile materials such as containers of freeze dried products, flasks, or the like, has a slide that displaces horizontally on the surface of the table. The table has a marginal section including a plurality of marginal tongues that independently pivot about an axis parallel to the edge of the table surface. The containers are moved from the surface of the transfer table across the tongues onto a support surface, or vice versa.

Abstract: Monitoring system for an electronic digital system. It includes an electronic digital control unit, a plurality of peripheral units, a bus system, the various system parts, and further an output circuit connected to the control unit. It further includes an output stage circuit with inputs connected to the output circuit, and outputs transmitting signals to the peripheral units for interrogating fault conditions therein, an interrupt trigger circuit with outputs connected to the control unit, and a digital filter connected between the monitoring system and the peripheral units for filtering out noise signals from the peripheral units.

Abstract: A method and apparatus for loading and unloading freeze-drying apparatus including at least one placement surface adapted to receive containers holding a product to be freeze-dried. The containers are placed on a table top of a transfer table, and the transfer table is brought into proximity with the placement surface in a chamber of a freeze-drying apparatus. A retractable frame assembly, movably secured to the transfer table, is used to transfer the containers from the transfer table top to the placement surfaces. The frame assembly is retracted from the chamber, and the freeze-drying process may then be implemented. Upon completion of freeze-drying, the frame assembly is introduced into the chamber, and is actuated to transfer the containers from the placement surfaces to the transfer table.

Abstract: Method of determining the rotational speed of a machine having a drive into which a setpoint value for the rotational speed has been introduced and a rotational-speed sensor from which a measured actual value is obtainable, which comprises feeding the setpoint value to a mathematical model of a controlled system formed by the drive and the machine, deriving from the output of the mathematical model a computed actual value, determining the difference between the measured actual value and the computed actual value, forming the absolute value of the difference, and, if the absolute amount of the difference is exceeded, passing on the computed actual value, and if the absolute amount of the difference is not exceeded, passing on the measured actual value; and device for performing the method as the determined rotational speed of the machine.

Abstract: Method of monitoring a clock signal includes bringing a bistable element to a first state through pulses of the clock signal and, upon the occurrence of pulses of a reference signal having a frequency lower than the frequency of the clock signal, scanning the state of the bistable element and outputting it as an output signal, and subsequently setting the bistable element to a second state.

Abstract: Data entry and display apparatus for a printing machine having a plurality of control elements having actual and desired position values for controlling machine variables which include ink and dampening fluid density and register positions, the control apparatus includes a control panel having a plurality of optical first elements for displaying and controlling at least one of the machine variables; a light pen having a contact point which includes a second optical element for operatively, optically engaging the first optical elements; timing means operatively engaging the first and second optical element for timingly coordinating the position of the contact point in spaced relationship with the first optical elements for entering nominal position values for at least one of the control elements into the control apparatus.

Abstract: A method and device for evaluating signals of an incremental pulse generator for generating at least two mutually phase-shifted angular speed signals includes counting the angular speed signals only if a permissible combination of the angular speed signals is present.

Abstract: A coding device for an electric cable plug connection having a plug connected to wires of a cable and insertable into a socket, both the plug and the socket being formed with a plurality of contacts, has a coding arrangement for assigning the plug to the socket in a correctly oriented position. The coding arrangement includes at least one jumper link connecting various of the contacts of the socket. The jumper link forms together with the cable connection an electrically interrogatable test loop.

Abstract: A freeze-drying apparatus includes a freeze-drying chamber; a plurality of horizontally oriented, vertically superposed and vertically displaceable shelf plates for supporting thereon receptacles containing the product to be freeze-dried; a plate shifting rod projecting into the freeze-drying chamber and being operatively connected to the shelf plates; and a drive situated externally of the freeze-drying chamber and being connected to the plate shifting rod for moving the plate shifting rod in directions into and out of the freeze-drying chamber. There is provided a sterilizing device including a sterilizing chamber adjoining the freeze-drying chamber and accommodating that length portion of the plate shifting rod which is to be introduced into the freeze-drying chamber during the plate shifting operation.

Abstract: A printing press, in particular an offset printing press comprising a plurality of individually operable setting motors, in particular for adjusting the inkfilm density profile, each setting motor being connected to a pick-up generating electric signals characteristic of the actual position of the setting motor at any given moment (actual values) comprises an electronic comparator arrangement (35, 44) which is supplied with the actual values and, in addition, desired values for the position of the individual setting motors (9) and which repeatedly scans the actual values sequentially in a cyclical time sequence and compares each actual value with the related desired value to form a setting signal for operation of the associated setting motor in the forward or reverse direction when a given positive or negative minimum deviation is exceeded.
