Title: Anaerobic decomposition of sludge - by directing sludge stream by nozzle into vertical venturi pipe and circulating and mixing sludge in container
Inventor: CLARK SIDNEY E
IPC: C02F3/12
Filed: 1992-03-13
Abstract: A new procedure for anaerobic decomposition of sludge has the following stages: filling a container with sludge to above the upper end of a vertical rising pipe whose open upper end is a little below the roof of the container and whose open lower end is a little above the floor of the container; maintaining the sludge at a temp. which is suitable for decomposition; delivery of a stream of sludge under pressure into the container via an upward-pointing nozzle located below a venturi section built into the lower part of the rising pipe, so that a suction is created at the entry to the rising pipe and a flow of sludge upwards through this pipe is maintained and the incoming sludge and the sludge in the container are thoroughly mixed. The container has a wide centre section and tapers towards the top and bottom. Partly treated sludge may be withdrawn from the container and returned to it via the upward-pointing nozzle, or raw untreated sludge (144) may be introduced via. the nozzle. The sludge may be pressed through a heat exchanger by the pump entering the nozzle, in order to regulate its temp. USE/ADVANTAGE - Used for anaerobic decomposition of sludge. Energy consumption is reduced and a high degree of mixing is acheived, and the appts. is relatively simple and is suitable for withstanding the harsh conditions which normally prevail inside composting containers.

Patent DE-4304674-A1 (DE)
Inventor: KOLB RAINER DIPL ING
IPC: H04B10/12
Filed: 1993-02-16
Abstract: A control unit drives the modules containing power transistors in industrial trucks. The electrical signal emitted by said control unit is converted into an optical signal, and that said optical signal is transmitted by means of an optical waveguide to the respective module and reconverted therein into an electrical signal. Two-way influence between the control unit and the power module, which occurs in electrical cabling and can lead to damage at both ends, is thus eliminated. In addition to electrical isolation, the removal of spatial constraints on the relative positioning of the components which is now possible results in further advantages for example in terms of the spatial configuration in the vehicle.

Patent DE-4332839-A1 (DE)
Title: Device for detecting (measuring) at least two movements
Inventor: THIERBACH PETER
IPC: G01D5/04
Filed: 1993-09-27
Abstract: In a device for detecting at least two movements, a lever (13) is mounted on two springs (15, 16). Every movement S or A acting on the lever (13) is assigned its own axis (19) or (20) of rotation. Since, when the movement is acting, the lever (13) executes a circular motion because of the axes (19, 20) of rotation located outside the centre of gravity, and thus executes a movement  DELTA x and  DELTA y, it is sufficient to detect and to recognize both the movement A and the movement F with the aid of a measuring device (23) arranged between the two axes (19, 20) of rotation. If a unique assignment of the measurement signals is dispensed with, it is also possible to use this single measuring sensor (pickup) (23) to detect a further, third movement. If, however, a unique assignment of the measurement signals is required, this third movement is to be detected with the aid of a second sensor, for example a Reed contact (30). <IMAGE>

Title: Latching mechanism with magnetic latching
Inventor: KOENIG HORST
IPC: H01H5/02
Filed: 1993-09-29
Abstract: In the case of a latching mechanism with magnetic latching, Hall generators (Se.1, Se.2) are used to produce signals when changing over between the two latched positions and when reaching a latched position. Since the hall generators give different output signals depending on the plurality of the magnetic field acting, reliable evaluation of the signals from the Hall generators is possible despite large production tolerances and correspondlingly different signal strengths. <IMAGE>

Title: Roll crushing mill
Inventor: OHNO YOSHIO
IPC: B02C23/02
Filed: 1994-02-14
Abstract: A roll crushing mill with a lateral feed has a housing (1), a turntable (4) provided in the housing, and a feed inlet shaft (10) which extends obliquely downwards through an upper side wall of the housing (1) and has a lower end which is arranged above the turntable (4). The feed inlet shaft (10) contains a cylindrical shaft body (11) and an insert (12, 12') mounted in the shaft body. The insert (12, 12') is made of a flexible, elastic material so that the inner surface of the insert is deformed in an irregular manner in conjunction with peristaltic movements and vibrations both due to its own weight and the sliding or dropping forces of the feed material which is fed through the shaft (10) and due to the elastic restoring force of the insert itself. Correspondingly, a layer of deposit of the feed material formed on the inner surface of the insert can be removed automatically at an early stage by the deformation of the insert without interrupting operation of the roll crushing mill. A steady and effective fine grinding operation can thus be carried out continuously. <IMAGE>
