Patent DE-3816047-A1 (DE)
Title: Circuit arrangement for acoustic partial-discharge detection
Inventor: STOYE HANS-JUERGEN DR ING
IPC: H02B13/065
Filed: 1988-05-11
Abstract: The invention relates to a circuit arrangement for acoustic partial-discharge detection on the insulation of electrical equipment, especially on solid-material and gas-insulated systems, cable terminations and voltage converters during normal operation. The aim of the invention is to reduce the influence of radiated interference fields on acoustic partial-discharge detection. The object of the invention is the detection of partial-discharges in the insulation of electrical equipment externally on the earthed parts of the equipment during normal operation. The object is achieved according to the invention in that a main amplifier, a high-pass filter and, after it, a secondary amplifier with a demodulator, are connected downstream of a piezoelectric vibration sensor, which is in a housing together with a preamplifier, and in that the noise level which is made visible and/or audible represents a measure of the partial discharges in the insulation of the measured electrical equipment.

Title: Drive for a vehicle
Inventor: KLAUS JOSEF
IPC: B60K7/00
Filed: 1988-05-24
Abstract: The engine for the vehicle is fixed directly on the wheel hub of the driven wheel or wheels and thereby acts directly on the wheel without means of transmission. The efficiency of the drive is thereby improved and the susceptibility to faults is reduced. An electric motor or a compressed air motor can be used as drive motor.
Patent DE-3817685-A1 (DE)
Title: Apparatus for receiving free-flowing bulk material through which a gas flow flows
Inventor: THIELEN WALTER DR
IPC: B01J8/12
Filed: 1988-05-25
Abstract: In an apparatus, free-flowing bulk material flows, as a result of gravitational force, through an essentially vertical chute, the opposing walls (2, 3) of which are constructed in a slatted manner for the passage of an essentially horizontally running gas flow. On at least one of the opposing walls (2), at a distance from the wall, there is arranged a perforated apron (6) which divides the bulk-material flow inside the chute into two partial bulk-material flows (7, 8). The partial bulk-material flow (7) bearing directly against the slats must be removed more often and separately from the partial bulk-material flow (8). In this case, malfunctions can occur during the removal of the bulk material which has entered between the slats. The novel apparatus is intended to improve the removal. On that surface of the apron (6) facing the assigned wall (2), there are provided flow breakers (10; 11) for superposing a transverse flow component onto that layer, bearing against the surface, of the partial flow (7) guided between the apron and the wall. The apparatus is preferably used in activated coke reactors for the desulphurisation of or removal of nitrogen from exhaust gases. <IMAGE>

Patent DE-3827748-A1 (DE)
Title: Worktable for receiving equipment systems, in particular for personal-computer systems
Inventor: LEHMEYER ALOIS DIPL ING
IPC: A47B21/03
Filed: 1988-08-16
Abstract: The invention relates to a space-saving, stable and free-standing worktable, in particular for personal-computer systems. The base part of the worktable is of T- or U-shaped configuration in plan, the central processing unit (CPU), accommodated in upright format underneath the standing area, taking up only the space which remains free in the case of the user's normal sitting posture. Owing to the spatial interlocking of the worktable with built-in CPU and the user's legs, only a minimum floor space is required. The free-standing, very stable worktable makes do with a keyboard width of approx. 50 cm, so that it can be placed against the desk at a right angle. This applies particularly if the worktable is provided with wheels. The depth of the worktable is determined essentially by the dimensions of the monitor and the keyboard. If required, a structure for peripherals, e.g. a printer, can also be fitted. This design of the worktable makes possible an ergonomically favourable sitting position with a minimum space requirement and a high stability. As a result of the arrangement chosen and the open mounting of the central processing unit, good accessibility to the operating elements and rapid access to the rear system connectors is possible. Moreover, the ventilation of the system units is in no way hindered.

Title: Method and apparatus for setting a preselected sweeping level of a revolving brush
Inventor: LEERS KONRAD DR ING
IPC: E01H1/05
Filed: 1988-12-07
Abstract: Method and apparatus for setting a preselected sweeping level of a revolving brush which is rotatable about an axis and is intended for cleaning surfaces, such as roads, runways or the like, wherein the distance between the axis of the revolving brush and the surface to be cleaned is altered to set the sweeping level, and wherein to measure the desired distance the brush diameter is measured by means of a sensor device and the distance of the axis from the surface to be cleaned is set in accordance with the brush diameter. In addition to the determination of the brush diameter, provision is made for the actual distance between the axis and the surface to be cleaned to be measured. In the event of deviations of the desired distance from the actual distance, a readjustment of the distance of the axis to the desired distance is carried out with the aid of an adjusting arrangement, in order to ensure that a preselected sweeping level is maintained.

Abstract: A gas-tight package of an apparatus, in particular breathing apparatus with a chemical which gives off oxygen, having a security device for checking the state of the package, which device acts on a partial region, of resilient design, of a wrapping which surrounds the apparatus and is subjected to a vacuum, the indication of the state of the device being recognisable by a visual marking on a housing which surrounds the wrapping, is to be improved in such a way that the security device indicates a loss of vacuum independently of the magnitude of the vacuum previously set, and that it can be installed regardless of the outer shape of the apparatus to be packaged and can be carried out with simple technical means without the geometry or force ratios having to be matched to one another. For this purpose, a tensioned and non-elastic banding (3) is provided as the security device, which grips at least partially around the periphery of the wrapping (2) designed as an evacuatable vacuum film, rests against the periphery, and has a band part (7) which exhibits the visual marking (6) (Figure 3). <IMAGE>

Patent DE-3908963-A1 (DE)
Inventor: LINDNER GUENTER
IPC: A01M7/00
Filed: 1989-03-18
Abstract: The invention concerns a vehicular device for applying plant treatment agents, with a spraying device and at least one tank (24, 24') for the plant treatment agent and a separate tank for a diluent, and also with at least one metering device (32, 32') for injecting measured quantities of the treatment agent into mixing chambers (31, 31') for mixing with the diluent. The metering devices (32, 32') used in the invention inject the treatment agent into the mixing chambers (31, 31'), into which the diluent is pumped under constant-pressure control (30), only when a given output pressure is exceeded. For each group (6) of spray heads in the sprayer unit (11) and/or for each spraying agent, a reciprocating-piston pump (1) is provided as the metering device (32, 32'). The pumps (1) are driven via electromagnetic transductors (8) at constant piston speed and stroke, and their associated mixing  chambers (31, 31') are located in the immediate vicinity of the spray nozzles (2, 3, 4, 5) of a particular group (6) of heads in the sprayer unit (11). The operating frequency of the reciprocating-piston pump (1) is controlled by frequency control of the electromagnetic transductor (8), as a function of the instantaneous speed of travel of the spraying device and the required output and concentration of the treatment agent, by means of a computing and control unit.
