Patent EP-0161912-A2 (EP)
Inventor: WEEKS KENNETH GEORGE
IPC: B01D24/24
Filed: 1985-05-09
Abstract: @ A method of operating a large scale slow sand filter in a clean water treatment plant is described in which the surface of the sand bed (3) is covered by a series of overlapping thin, flexible, water permeable sheets (8) to form a protective filter layer (7) so that the Schmutzdecke forms on the protective layer (7) instead of on the surface of the sand. When the Schmutzdecke is to be removed, this is done either by removing it from the protective layer (7) in situ, for example by suction dredging, or by removing the individual sheets (8) of the protective layer together with the Schmutzdecke, from the filter. A clean protective filter layer is then formed on the surface of the filter bed for continued operation of the filter. If desired, several protective filter layers (7) may be provided one on top of the other so that it becomes unnecessary to instal a clean filter layer (7) each time one is removed in order to remove the Schmutzdecke formed during the previous operation run of the filter.

Abstract: A trough-like vibrating conveyor is used to sort and separate two differently shaped components in a mixture of materials of value. The mixture is separated into generally cylindrically shaped parts, such as hollow parts, and generally flat-shaped parts. The conveyor includes at least two unbalanced motors each arranged on an opposite side of the conveyor extending in the conveying direction. Further, the motors are offset relative to one another in the conveying direction. The vibrating conveyor affords a simple operation for separating the differently shaped components of the mixture as the mixture moves between the inlet and outlet ends of the conveyor and particularly for separating any glass particles. The conveyor requires little in the way of technical or personnel expenditure.

Abstract: A digital signal detector utilising a detected input digital signal derived from a reference square wave - (13) and a received pulse train (12) to establish phase and frequency variations between the reference signal and the received signal. The detected signal (12) and the reference signal (13) are coupled to up-down counters (17, 18, 45, 46) wherein overflow counts from preset values are obtained which are representative of the frequency and phase difference between the reference and received signals. These overflow counts are utilised to establish phase and frequency error correction signals which may be coupled to control the reference oscillator to provide frequency and phase lock between the reference and received signals.

Abstract: The present invention provides a process for the continuous production of microbially shelf-stable paste-filled shredded cereal biscuits having an extended shelf-stable plurality of textures. A first plurality of net-like sheets of cereal dough are continuously laminated, followed by continuous depositing of at least one extrudate rope filling upon the first plurality of net-like sheets. A second plurality of net-like sheets is continuously laminated upon the at least one extrudate rope to obtain a filled laminate. Each of the net-like sheets has a plurality of generally parallel longitudinal strands and a plurality of crosshatchings which are generally perpendicularto the longitudinal strands. The filled laminate is cut to enrobe the filling and the product is baked. The number of crosshatchings of the net-like sheets adjacent to the filling is greater than the number of crosshatchings of the net-like sheets which are further removed from the filling. The use of fewer crosshatchings provides a region of light texture which enhances the impression of a soft or chewy filling. The use of a greater number of crosshatchings in the net-like sheets which are adjacent to the filling: 1) prevents substantial penetration of the filling through the adjacent sheets during deposition of the extrudate rope and during baking, 2) enhances the chewiness of the filling, and 3) reduces lateral movement of the longitudinal strands so as to facilitate consistent deposition of the fitting rope in an at least substantially straight line. The region of light texture is preferably limited to the interior layers of the biscuit.

Abstract: A capacitive transducer is disclosed for measuring the rotation of a shaft including relatively movable rotor and stator elements. A unique arrangement of capacitive plates is mounted on the stator and rotor for producing a signal indicative of shaft rotation using direct current excitation but without requiring brushes, commutators or slip rings. A preferred embodiment may further include co-planar first, second and third stator plates or alternatively, cylindrically shaped stator and rotor plates. The number of stator plate segments included in each of the first and second stator plates, of the embodiment employing co-planar plates, may be an even multiple less than the number of rotor plate segments. By this arrangement, a circumferential gap may be provided in the first and second plates through which an extension of the third stator plate may be located to reach an output signal terminal located adjacent to but beyond the radial extent of the first and second stator plates.

Abstract: In the comminuting device (1), which is based on German Patent Specification 2 934 792, flexible material is introduced into the housing (2) containing the cutting mechanism (8) through a central receiving device (4) and stiffer material through a separate branch receiving device (5). The cross sections of the feed-in openings (13) depend on safety regulations, and this means that branches and similar stiff material has to be prepared so that it can be introduced into the branch receiving device (5). To avoid this effort, the invention proposes designing the feed-in opening (13) of the branch receiving device (5) in a keyhole shape (14, 15). This makes it possible to introduce twisted or spreading branch structures into the device (1) without special preparation and without the safety regulations being ignored. <IMAGE>
