Abstract: The invention relates to a device for carrying out integrity tests on filter elements by means of test gases, comprising a device housing (3), with an electronic controller (4), arranged therein for regulation and control of the progress of a test programme for filter elements, a filter housing (6), for housing a filter element (2) under test, a pneumatic unit (5), connected to the controller (4) and the filter housing (6), in particular for the generation and measurement of gas pressures, an electronic memory unit (10), which may be connected to the filter element (2) under test and a communication unit (13?), connected to the controller (4), for the exchange of data between the controller (4) and the electronic memory element (10). The communication unit (13?) is preferably embodied as an antenna (14?) and the electronic memory element (10) as a transponder (11). In addition to the device a method for carrying out integrity tests and a computer programme product are also disclosed.

Abstract: Device and method for sterility testing, in particular of pharmaceutical products, includes a closed sterility test system having at least two test containers, in each case having an integrated test filter, an outlet connecting branch arranged below the test filter and an inlet connecting branch which is arranged above the test filter and can be connected with a tube connection via a sampling device to a sample container. The tube connection of the test container in each case has a distributing component via which a fixed tube connection to an associated nutrient medium container is formed and can be used to feed an associated nutrient medium to the test container.

Abstract: A media validation and registration system includes media storage devices which contain a quantity of content thereon, a user computer processor assembly structured to access a select media storage device, a verification module, and a communicative link between the verification module and the user computer processor assembly. Each media storage device includes a unique unit identifier, the verification module identifying the unique unit identifier of the select media storage device and receiving user information associated therewith. The verification module is also structured to apply supplemental content in association with a first user whose user information is associated with the unique unit identifier for the select media storage device, and to allow the user to register the media storage device through a computer network, e.g., the Internet, and also to verify the status of the registration by going to a website of the publisher or distributor of the media storage device.

Abstract: A bend-straightening machine with a vertically movable table for straightening long workpieces is provided. The bend-straightening machine of the present disclosure includes straightening supports for supporting a workpiece mounted on a movable table which moves in a vertical plane driven by a driving mechanism. The machine is constructed as a rigid frame including a base for supporting at least one upright column. A fixed bridge is joined to an upper portion of the upright column and supplies a stationary surface for mounting at least two workpiece holding fixtures, which grip the ends of the workpiece, allowing the workpiece to be rotated. Also, mounted to the bridge is at least one straightening punch which remains stationary during straightening. The moving table and straightening supports act vertically upward on the workpiece causing the workpiece to bend, i.e., straighten, when it contacts the straightening punch.

Abstract: The invention relates to a crossflow-filtration method for beverages, in particular beer, which comprises the following steps: a) the feed liquid is introduced into a filter module by means of a tangential flow through a filter membrane (6) in a first direction, whereby the filtrate flow on the filtrate side (19) of the filter module is maintained within predetermined threshold values; b) the entry pressure is reduced and the filter is backflushed by surges of filtrate initiated by a reversal of the flow direction transversally to the membrane; c) the feed liquid is optionally introduced in an inverse flow direction to that of step a) and the concentrate is evacuated on the non-filtrate (7) side of the module; d) the entry pressure is reduced and the filter is backflushed by surges of filtrate initiated by a reversal of the flow direction transversally to the membrane; e) steps a) to d) are repeated until the filtrate flow lies below the lower predetermined threshold value; f) to k) the filter is emptied by a

Abstract: The invention relates to a filter module and an apparatus for the static filtration of liquids using filter cells having deep bed filter layers and using spacer layers. According to the invention the filter module has a stack of n filter cells and n+1 spacer layers for filtrate and at least one channel arranged in the interior of the filter module. In this case n is ?1. The filter cells consist of a draining spacer layer for feed liquid and deep bed filter layers which are arranged in a sandwichlike manner thereto and which are joined to one another at their circumference toward the at least one channel at the rim via a sealing compound and wherein the spacer layers for filtrate are furnished with the sealing compound at the rim on their external circumference.

Abstract: A cutting head for a string trimmer is provided which accommodates any string gauge thickness and may be easily and quickly re-threaded upon failure of a string previously disposed therein. The cutting head has spring-biased clamping members which are each mounted within a rotatable clamp housing within the head, such that, as a string encounters a solid object, the clamping member and its associated housing are rotated about a generally vertical axis so as to obviate or minimize the development of a stress concentration in the string in the vicinity at which it is engaged by the clamp housing.

Abstract: A rehabilitation and fitness trainer apparatus includes a handle frame of generally U-shaped configuration, with two telescopic members attached at an angle to the base of the U-shaped handle portion, a generally U-shaped base frame including an elongated cross bar and two side members which extend rearwardly and at an outwardly extending angle from the elongated cross bar, and with the cross bar including a pair of elongated members that extend generally upwardly and rearwardly for cooperating and telescopingly engaging the pair of telescopic members extending from the handle frame. A locking device is provided for vertically adjusting and maintaining the vertical distance between the handle frame and the base frame in order to accommodate a wide variety of users of the apparatus.
