Title: Sound-suppressed disposable saliva suction nozzles
Inventor: MANTEL JUVAL DR ING
IPC: A61C17/08
Filed: 1987-10-14
Abstract: Aspiration of saliva from the mouth of a patient by the dentist produces sounds which disturb both the patient and the medical staff. These sounds produced in the aspiration process can be eliminated, however, for example by the invention described below of a sound suppressor or by sound-suppressed suction nozzles. The nozzles used for aspiration of saliva comprise curved, usually transparent plastic tubes (often reinforced by wires). If a sound-absorbing, preferably fibrous, material were introduced into such a tube, a certain restriction of the saliva flow would result. On correct placement of this material, the noise could be reduced. <IMAGE>

Title: Air pump for small pressures, having differential-pressure-controlled pneumatic solar-energy drive
Inventor: STRUNZ DIETMAR DIPL ING
IPC: A01K63/04
Filed: 1987-11-28
Abstract: By means of insolation, the alternate compression of two bellows and the displacement of the air contained in the latter to an air consumer is achieved. The air pump installation functions automatically as long as there is sunshine at the site of the installation. For the purpose of controlling the air pump installation, use is made of floats, valves, sun screens and possibly also permanent magnets, which are systematically connected to one another in such a manner that the insolation is continuously unscreened and screened and the bellows are correspondingly caused to press and to suck. The air pump installation provides preferably approximately 50-100 watts, functions without evaporators and without rotating engines and machines and is, for example, suitable for aerating fish-feeding or composting plants. The maintenance of the air pump installation requires only simple tools so that the air pump installation is suitable for use in sunny latitudes where there is industrial underdevelopment.
Patent DE-3743401-A1 (DE)
Title: Circuit arrangement for telecommunication switching systems, particularly telephone switching systems, with facilities for acquiring switching events arriving in a sequence
Inventor: DAISENBERGER GEORG
IPC: H04Q3/00
Filed: 1987-12-21
Abstract: A device for dividing an irregular sequence of individual switching events which can be detected in total sets into a number of subsets for the purpose of forwarding the former to a corresponding number of information sinks consists of counters allocated to the latter, which are supplied with information indicating the individual switching events such as call switching signals indicating calls, via a distribution device. Each counter is incremented cyclically and in each case with each information item supplied to it by a number of steps which corresponds to a quota relating to the respective subset. Each counter can be set to a counter-individual counting cycle - in the quantitative sense - which is the result of the sum of all quotas. If a counter completes its counting cycle, it starts again from its initial position in the overflow. The distribution device successively forwards an information item in cyclic sequence to one or more of these counters until a counter overflows, whereupon this information item is supplied to the information sink allocated to this counter. Distribution of the information items as determined by the quotas.

Inventor: MUENCH RUDOLF
IPC: D21F7/06
Filed: 1988-03-11
Abstract: To achieve uniform and regular adjustment of a slice bar (1) within the limits of its elastic deformability, it is proposed that the slice bar (1) provided at the discharge gap of a headbox on a paper-making machine is capable of being moved by positioning elements (2) driven by servo-motors (5), the positioning elements being arranged at suitable intervals parallel to the slice bar (1) and connected to it so as to be able to apply a force to the connecting points (3) on the slice bar (1). It is possible to adjust each servo-motor (5) in a setting procedure to provide the currently-desired speed of thrust and the currently-desired length of stroke (6) for the positioning element (2) prior to the start up of the servo-motor (5). All the servo-motors (5) are started at the same time or, after the desired set-point position of the slice bar (1) has been reached, are switched off simultaneously. Electric stepping motors working in unison are particularly suitable for this purpose. The device and the setting procedure it offers are capable of being controlled and programmed by known electronic means.

Title: Apparatus for loading palettes with piece goods in layers
Inventor: MUELLER FRIEDHELM
IPC: B65G57/06
Filed: 1988-03-26
Abstract: In apparatuses of this type, a substantial simplification is to be provided, in particular in terms of construction, so that robot-like storing and assembling apparatuses can be dispensed with and use can be made of partially known apparatuses which have proved themselves and are designed so as to be reliable for high plant capacities. As a solution, the invention provides that the intermediate station (4) arranged after the push-across station (3) is constructed as a line formation and gap divider station and has a linear module (9) which is effective below the conveying plane for the piece goods and through the supporting surfaces (8), can be brought into connection with the bottom (10) of the piece goods and/or an end face, can be driven in accordance with the required layer pattern and can be moved into any desired position with the relevant piece goods (10', 13, 15). The apparatus can be used in storing and palettising technology. <IMAGE>

Abstract: In order to attain an extremely high reaction rate of sample and reagent solutions at a reaction line in a method of flow injection analysis, the solutions are injectedly supplied thereto alternately and respectively at a predetermined trace amount through independent two flow lines which are kept so as not to produce pulsation within the solutions. A thermostat bath accommodating the reaction line and a back pressure coil connected to the flow lines also make the aforementioned reaction rate stable and regular. Spectrophotometric flow cell (see Figure 3) succeeding the flow lines for the analytical determination of the sample solution has a specific range of optical path length and such optical path diameter which is widely diverged from its inlet. <IMAGE>

Title: Separating strip for a comminuting appliance
Inventor: LAUER FRITZ DIPL ING
IPC: A01F29/09
Filed: 1988-07-08
Abstract: Separating strips of conventional type have a bevel on their side faces, so that these extend at an inclination relative to the front or the rear face; accordingly, teeth ground into this bevelled region have little material. A separating strip, in which the bevelling costs are absent and which has a longer service life, is therefore to be provided. The separating strip (10) according to the invention has side faces (16) which extend at an angle of approximately 90@ relative to the front and the rear face (12 and 14) and into which the teeth (20) are milled or ground with a rectangular impact face (28). Separating strips of this type are used particularly in choppers on combine harvesters. <IMAGE>

Title: Process and apparatus for thermal decontamination of filter dusts and other residues
Inventor: ATZGER JUERGEN DR ING
IPC: F23G5/08
Filed: 1988-08-10
Abstract: The process and apparatus according to the invention provide a decontamination of dioxin- and furan-containing dusts, which simultaneously also contain heavy metal compounds, by subjecting them to thermal decontamination in an inductively heated crucible furnace.   The material to be decontaminated is put into the liquid state at temperatures between 1400 and 1600@C and appropriate residence time, toxic portions, such as dioxins and furans, being completely destroyed and heavy metals being bound so that they cannot be leached out. The material is tapped after a melting process and is cooled in a quenching vessel. Grinding is not necessary. Gaseous portions from the crucible furnace are passed through a high-temperature section, then quenched and particulate constituents are separated off in a high-performance deduster. The crucible furnace can be operated either batchwise or continuously; in the continuous mode, the outlet orifices are dimensioned in such a way that, from a defined temperature, the melt drains off by itself and throughput can be controlled via the furnace heating.

Patent DE-3841962-A1 (DE)
Title: Device for manually clamping and releasing a disc-shaped tool on and from the working spindle of an electric tool
Inventor: KRETSCHMAR PETER DIPL ING
IPC: B27B5/32
Filed: 1988-12-14
Abstract: In the case of a known device of this type, the clamping nut can be coupled to at least one of the flanges receiving the tool between them, with the aid of a wrap spring which can be tensioned and relaxed by an adjusting member. Owing to operationally related increasing releasing torques, the discharging of the flange concerned from the clamping pressure occasionally gives rise to difficulties in this arrangement. The new device is to permit, with a minimum structural expenditure and spatial requirement, manual relieving of the flanges without there ever being any problems, even in the case of increased releasing torques. In the clamped state of the tool (28), a relative movement between the clamping nut (11) and the flange (13) is prevented by positive locking. The positive locking can be removed by actuating the adjusting ring (17) and, as a result, the flange can be relieved of the clamping pressure for the tool (28). <IMAGE>

Patent DE-3902095-A1 (DE)
Inventor: FISCHER HELMUT
IPC: G01B7/06
Filed: 1989-01-25
Abstract: In the case of known probes for the measurement of the thickness of thin layers, its convex end face (64) presses indentations into the material due in part to the mass of the probe and its cable and which can falsify the measurements. In order to reduce the mass to be considered upon impact as far as possible to zero, the half-pot core (52) together with coil (61) is resiliently mounted by springs (99), (101), (109) to probe body (12) so as to be axially moveable therein. The influence of the cable and an associated active circuit (26), which emits at its output a coded signal which is a function of the layer thickness is eliminated by making the cable and circuit lightweight. Sapphire 63 mounted in core (52) may be omitted, in which case there is a solid central core having a hemispherical surface positioned in a pot-shaped cap of polyimide. The small polyimide cap is stuck with its inner surfaces onto the surfaces touching the small cap by an acid resistant and alkali resistant adhesive. <IMAGE>

Title: Fibre-reinforced synthetic-resin concrete as load-bearing element for increasing the calculability of failure mechanisms for use in aggressive liquid and/or gaseous media
Inventor: BERGMANN ROCHUS DR ING
IPC: E04C5/07
Filed: 1989-02-10
Abstract: The invention presents a process to improve the properties of a synthetic-resin concrete by means of fibre laminates and thus effectively to prevent the sudden failure of structures and, at the same time, to improve the impermeability with respect to aggressive media of a vast range of states of aggregation. The process is characterised in that synthetic-resin concretes, as required, are reinforced in a shear-resistant manner in lozenged or square form with fibre laminates which correspond to the chemical requirements of the media enclosing the structure. By virtue of the structure selected, for the first time the good elastic properties of the synthetic-resin concrete and the likewise elastic properties of fibre laminates are combined such that the entire load-bearing behaviour is elastic/plastic to marked extent. This results in the fact that possible fractures do not appear suddenly, but are preceded by large deformations, this leading to a reduction in safety factors in the dimensioning and thus permitting more cost-effective structures than hitherto.
Patent DE-3905212-A1 (DE)
Title: Mobile measuring device for charge anomalies in the air near the ground for the purposes of prospecting for deposits
Inventor: SUTTOR FRIEDRICH ING GRAD
IPC: G01T1/169
Filed: 1989-02-21
Abstract: The invention relates to a mobile high-sensitive measuring device for charge anomalies in the air near the ground for the purpose of indirectly prospecting for deposits. Radioactive emitters (radiators) mark the air surrounding them with long-lived ions. The concentration measurement of these charges is suitable for determining the emission sources. The portable measuring device contains a detector chamber having a control electrode, a fan, an amplifier with evaluation and control electronics, a display instrument and a limit monitor which raises the alarm optically and acoustically, and a battery supply. A fan sucks ca. 200 litres per minute through a condensor chamber. The ions contained in the airflow discharge the condensor within a selectable cycle time. The short recharging pulse, which is in the range of microseconds, is proportional to the charge removed and is supplied via an amplifier, a peak voltage detector and a sample-and-hold circuit. The measured value is available as a direct voltage and is displayed on an analogue or digital instrument. A limit monitor which raises the alarm optically and acoustically is advantageous for prospecting. The expensive insulator technology is necessary in order to prevent false measurements even in the case of rugged environmental conditions and high atmospheric humidity and when operation is vehicle-bound. The control electrode permits the measuring range to be adapted rapidly without the need to change the cycle time.

Title: Method for optical reflection measurements and a densitometer and printing control strips for carrying it out
Inventor: KRZYMINSKI HARALD DR
IPC: B41F33/00
Filed: 1989-03-22
Abstract: The method is specific to optical reflection measurement on printing control strips on multicolour printed sheets, using a densitometer, with whose measuring unit specific measuring fields of the printing control strip are measured and the measured values are converted so as to be evaluable in the computer of the densitometer. In order to carry out the measuring process simply and quickly and to be able to design the device for carrying it out relatively simply, specifically not only with respect to its constructional expense, but also with respect to its programmability, the process according to the invention is carried out in such a way that a printing control strip having measuring fields arranged corresponding in size and according to colour and type (full-tone, middle-tone, under-tone), and that, for carrying out the measurement, a plurality of sensors is simultaneously brought into position on correspondingly spaced measuring fields of the printing control strip and, in so doing, the full-tone, middle-tone and under-tone densities of the printing inks involved in the image make-up and correspondingly present in the printing control strip are measured with a maximum of two measuring processes.
