Title: Ball valve
Inventor: JAKOB DIETER DIPL ING
IPC: F16K5/06
Filed: 1988-09-09
Abstract: The invention relates to a ball valve for shutting off a medium, particularly a fire-extinguishing medium. Inserted loosely into a tubular valve housing is a ball which, in the lower part, rests by means of a spigot against a guide piece and, in the upper part, rests by means of a stop edge formed by a recess against the driver of an operating shaft. The ball is held in the desired position by the sealing lip of a sealing element. This considerably simplifies manufacture and assembly.

Title: Sheet-conveying drum for sheet-fed rotary printing machines
Inventor: WIRZ ARNO
IPC: B41F21/10
Filed: 1989-02-01
Abstract: A sheet-conveying drum for sheet-fed rotary printing machines is proposed, in which the jacket surface is provided with a jacket foil (20). It has been shown that, when processing types of paper of different thickness, particularly thin sheets tend to continue running on the impression or rubber-covered cylinders. In order to avoid this continued running, it is proposed to provide a sheet-conveying drum (11) with an element with which the diameter of the sheet-conveying drum (11) can be changed. For this purpose, carrier elements, consisting of a metal carrier plate (21) with supports (22) are arranged below the jacket foil (20), which carrier elements support the jacket foil resiliently over its entire surface. The jacket foil (20) is fixed on the sheet-conveying drum (11) by means of an adjusting device (25). Tensioning the jacket foil (20) using the adjusting device (25) causes a change in the outside diameter of the foil due to the resilient effect of the supports (22). This therefore provides a possibility to adapt the sheet-conveying drum (11) to different thicknesses of paper. <IMAGE>

Title: Bag label and its use, and method for filling bag labels and for fitting articles with accessories
IPC: B65D5/42
Filed: 1989-02-07
Abstract: A bag label (12) can be stuck on an article by means of a labelling machine in order to fit the article with an accessory, for example a product sample, assembly material or the like, to form a sales unit. The bag label (12) consists of a top sheet and a bottom sheet which form a bag for the accessory. On the back of the bottom sheet there is an adhesive layer (23, 24) with which the bag label (12) is stuck on the article. The top sheet (20) can be torn open along perforation lines in order to remove the accessory, for example a product sample (15), from the bag label (12). The bag label (12) is combined with an ordinary, single-ply self-adhesive label (11) to form an overall label (10) (Figure 1). <IMAGE>

Title: Arrangement for measuring the rate of flow in the case of the pneumatic and hydraulic conveyance of fine (small) grained bulk materials
Inventor: LOETSCH KLAUS DIPL ING
IPC: G01F1/712
Filed: 1989-03-21
Abstract: The invention relates to an arrangement for measuring the rate of flow in the case of the pneumatic and hydraulic conveyance of fine grained bulk materials in reaction chambers or other units. The aim of the invention is to obtain an accurate and rapid measurement of the rate of flow as a precondition for controlling the mass flow. The object consists in making use of known electronic modules to propose an arrangement which delivers significant measurement signals in order to implement reliable determination of the rate of flow. According to the invention, an arrangement for measuring the rate of flow is proposed which consists of capacitive measuring (sensing) probes comprising two channels, each having two pairs of electrodes, a differential element and a common delay correlator. The electrodes of each pair of electrodes are arranged outside on the conveyor tube at an angle of less than 180@ to one another in the radial direction. Each pair of electrodes is assigned an AC voltage generator with a different or identical frequency for the simultaneous control of the evaluation circuit, it being the case that the electrodes of each pair of electrodes can also be located opposite one another at 180@, or that also optionally all the electrode pairs can be assigned only one AC voltage generator.

Title: Method and apparatus for the differential cooling of broad, flat products
Inventor: BUDACH MARINA DIPL ING
IPC: B21B45/02
Filed: 1989-05-13
Abstract: The invention relates to methods and an apparatus for the differential cooling of broad-flat products, preferably those made of steel, with a liquid coolant during their rectilinear movement. The aim of the invention is to improve economy by increased product quality resulting from a more homogeneous structural configuration or reconfiguration in the broad, flat product to be cooled, both in the transverse direction and in the longitudinal direction. This will result in more uniform material properties and lower internal stresses. The object of the invention is to guarantee as small as possible temperature differences between the centre and the edge of the material of the broad, flat product to be cooled, not only in the transverse direction but also in the longitudinal direction. According to the invention, the object is achieved by virtue of the fact that a method is carried out with the cooling apparatus required for it, ensuring the local variation of the cooling intensity of individual cooling beams during the cooling operation on an individual broad, flat product. The cooling apparatus required for this purpose comprises, in a known manner, cooling beams consisting of a main tank and distributor pipes attached to it. According to the invention, the main tank of the cooling beams contains adjusting devices which allow the continuous local variation of the coolant stream emerging from the respective cooling beam via the distributor pipes.
