Patent DE-3739667-A1 (DE)
Title: Practice explosive body which can be used a plurality of times
Inventor: SASSMANNSHAUSEN ULRICH DR
IPC: F42B8/28
Filed: 1987-11-24
Abstract: If a practice explosive body (which contains an inert compound instead of explosive but is otherwise no different from a live explosive body) which is fastened by means of a double-sided adhesive strip (3) is removed from the object again at the end of a practice, the film (2) into which the explosive body is packed is generally destroyed during removal. By means of a separating film (5), in conjunction with a further double-sided adhesive strip (6) which is introduced between the packing (2) and the double-sided adhesive strip (3), the packed inert compound can be removed from the object without the film (2) being damaged, if the film (5) is pulled by means of a tear-off device (7) such that a notch is formed between the separating film (5) and the outer double-sided adhesive strip (3) since the adhesion forces on this tearing line are insufficient, while in contrast removal is impossible when the practice explosive body is fitted such that it is flat against the object. <IMAGE>

Title: Shearer loader with two hydraulic winches
Inventor: HENRICH FRIEDHELM
IPC: E21C27/02
Filed: 1988-03-02
Abstract: In shearer loaders which are equipped with two winches, obtaining adequate synchronism of both winches presents difficulties, which can lead to disadvantages especially in the idling position of their fluid pumps. The proposed solution is intended to ensure that the adjusting members of the fluid pumps of both winches are always in their idling position when the idling position has been activated via the manual actuation, but it is also intended to guarantee substantial synchronism of both winches during the winning operation.   To this end, it is proposed to allocate one incremental shaft encoder (19, 19a) each to the servomotors (17, 17a) of both winches and to provide a control amplifier (24) connected to both shaft encoders (19, 19a). The output signal of the control amplifier (24) acts on the directional control valve (23a) of the control circuit (9a) and adjusts its fluid pump (2a), not equipped with a preselector member (10), in the desired direction. <IMAGE>

Title: Process and installation for the continuous production of profiled bars, for example handrail profiles, from plastic
Inventor: OEPEN KARL-HEINZ
IPC: B29D99/00
Filed: 1988-03-16
Abstract: For the production of profiled bars, for example handrail profiles, from plastic, in particular flexible polyurethane integral (structural) foam, it is proposed to apply on the mould an already solidified or cured film strip of highly compressed polyurethane plastic in a thin and closed layer, at least to the moulding surfaces of the outer mould, and then transport the said strip continuously and progressively with the mould. Thereafter, the plastics component mixture is introduced into the mould chamber and made to foam against the layer covering, intimately bonding with the latter in the process. This type of production of profiled bars increases the service life of the mould considerably and additionally ensures that the surface of the profiled bars is insensitive to mechanical stresses, for example scratching.

Patent DE-3813409-A1 (DE)
Title: Wristwatch
Inventor: OSTERHAGE WERNER
IPC: G04G9/08
Filed: 1988-04-21
Abstract: Wristwatches with digital displays found on the market today are all characterised in that the digital display is mounted in a static position inside a housing. The watches themselves are arranged on a bracelet or between a two-part divided bracelet. As a consequence, the bracelet is an aid for the fastening of the watch on the wrist of the carrier and not for the watch itself. The disadvantage of such watches is firstly the design having a single digital display in only one housing. In the case of failure of this digital display, the watch is without function. It is further disadvantageous, that they can only be read at a specific viewing angle. The proposed development of an endless chain of bracelet elements (1) to form a multiple digital display (2-5), in connection with a new electronic circulating technology of this multiple digital display (2-5) from bracelet element (1) to bracelet element (1), permits the conversion of the classical housed wristwatch with a static digital display to a wristwatch having a dynamic digital display. Furthermore the wristwatch having a peripheral multiple digital display (2-5) guarantees readability at all viewing angles. <IMAGE>

Title: Lift with an economy drive
Inventor: MAHLER HEINRICH
IPC: B66B1/28
Filed: 1988-06-11
Abstract: A lift installation, to whose electric motor a frequency converter is assigned, via which the starting current is reduced, specifically by about 50%, serves for the conveyance of persons and loads. In the motor lead behind the frequency converter, a motor filter configured for the high frequency of the frequency converter is connected. Furthermore, a braking chopper and a correspondingly designed electronics card are assigned to the frequency converter. By means of the use of the filter, the braking chopper and corresponding design of the electronic card, designed as a desired-value board, it is possible to eliminate completely the unacceptable noises occurring until now in frequency converters of this type. Furthermore, during movement of the lift installation, a current saving of the order of about 60% can be achieved, because the frequency converter idles in the upwards, empty state, when using the braking process from fast drive to slow drive and consumes very little power in the downwards, empty state because, especially in the starting-up process, the starting current is correspondingly reduced by around 50%. <IMAGE>

Title: Apparatus for separating off and pressing out solids from liquids
Inventor: EICHLER DIETRICH DR
IPC: B30B9/20
Filed: 1988-10-14
Abstract: The invention relates to an apparatus for separating off and pressing out solids from waste waters (effluents) having a low solids content from 0.3%; for example for separating off and pressing out fibrous constituents from thin slurries (liquid manures) which arise in the removal of liquid manure from industrial animal production units. The aim is to achieve a high degree of separation in order to achieve in this way an improved availability of the solids as compostable, storable or land fillable material, in agriculture, for example, for special fertiliser purposes and the use of liquid phase in economical irrigation without the risk of causing blockage, or the formation of sediment and scum. The object is achieved according to the invention in that, by establishing a difference in height between the feed and screened liquid at a rotating screen drum having gap widths of 0.15 to 0.6 mm, a concentration to give a still free-flowing sludge is achieved such that in dewatering to give a crumbly product in a press component having gap or whole widths of 0.3 and 3 mm, the fines are incorporated in the solids carpet forming and can be discharged with the solids pressed out.

Patent DE-3905956-A1 (DE)
Inventor: HERZER RUEDIGER DIPL ING
IPC: G01N29/07
Filed: 1989-02-25
Abstract: An apparatus for measuring propagation times of ultrasound in workpieces has an RF pulse generator which generates high frequency wave trains with few oscillation periods and which is connected to an ultrasonic transmitter/receiver whose output signal (71) is applied to a comparator. The comparator generates spikes (80) when the ultrasound echoes (71) pass through zero (79). Provided between a gating circuit and a counter is an AND gate to whose second input the output signal of the comparator is applied. The time gate (75) of the gating circuit can be positioned by computer control a quarter wavelength of the ultrasound ahead of the maximum (76) in the envelope curve signal (72) of the amplified ultrasound echoes (71), with the result that their identically situated steepest passage through zero (78) triggers the start or stop pulse (81) of the counter. The time gate (75) is at a fixed interval in time with respect to the instant in time A set by the threshold value (73), with the result that the time gate (75) still reliably detects the passage through zero (78, 81) to be separated as a result of propagation time changes affecting the envelope curve (72) as a whole, for example if the workpiece to be measured has a conical enlargement.
