Patent DE-3037365-A1 (DE)
Title: Private telephone system - has priority and group facilities allowing change of priority through local instrument addressing central control memory
Inventor: ACHMUELLER ANDREAS ING GRAD
IPC: H04M3/38
Filed: 1980-09-30
Abstract: The system is used to increase the versatility of priority call selection and group connections. The former can be particularly useful if the telephone system is also used for emergency communications, for e.g in process or power plants. Certain, or, if necessary, all instruments (TS1,TSN) on the system are provided with controls for selecting a range of priorities (KN11....KM1X;KMN1...KMNY). A call and associated selected priority is put into a working store (MU) in the central processor (CC) where it is checked. If the priority has changed then the store is updated. If the called extension is engaged then by exercising a higher priority the existing call can be interrupted. Also priorities can be established even if the system is already fully occupied at the moment at which a new priority call is entered. As a precaution against conflicting instructions, only one extension can exercise top priority at any one time.

Title: Pressure regulator with diaphragm protection - has internal sleeve to prevent excess diaphragm deflection due to over-pressure
Inventor: GOTTFRIED JOSEF
IPC: G05D16/06
Filed: 1980-11-07
Abstract: A pressure regulator of the type used with propane gas cylinders is designed with an auxiliary facility to prefent bursting of the control diaphragm in the event of over-pressurisation. Gas flow is through the regulator across an orifice that has an exit area dependent upon the position of a control lever. The pivoted lever is moved by a diaphragm that resists the pressure in the chamber with a spring bias force, that is set by an adjuster. A cylindrical projection prevents undue deflection of the diaphragm in the event of over-pressure.

Title: Surface or underground irrigation device - is of sintered plastics giving drip-feed
Inventor: LORENZ HELMUT DR
IPC: A01G25/06
Filed: 1980-12-10
Abstract: The drip-feed device is designed to perform surface or underground irrigation of crop plants and is made of sintered plastics or other material. The sintered, i.e. water-porous, surface reduces the pressure in conjunction with the earth so as to produce a drip-feed. The device can either be connected by a hose to a feed pipe, or fitted in the pipe itself. The design virtually excludes trouble due to choking, and so allows a high degree of automation of the irrigation system.
Patent DE-3046771-A1 (DE)
Title: Digital=to=analogue converter - resolution being nearly doubled by reducing repetition frequency of shift clock during register shift period
Inventor: KUHLMANN JOACHIM DIPL PHYS
IPC: H03J5/02
Filed: 1980-12-12
Abstract: This D/A converter, which includes a shift register followed by an integrator, gives higher resolution without the need for increasing the number of register elements. This is achieved by progressively reducing the repetition frequency of the shift clock during a register shift period. This results in almost doubling the analogue data for the same number of elements. The shift register (SR) is clocked by a shift clock (TG) derived from a clock pulse (T), but whose repetition frequency decreases exponentially during one shift period as a result of the action of a counter (Ql-Qn) and OR-gates (Ul-Un). Principal application is for the control of brightness, volume, contrast and colour hue in radio and TV-receivers.
Patent DE-3106872-A1 (DE)
Title: Rack arrangement and its use in an opening and closing device for roof flaps and skylights
Inventor: JENSEN NIELS THORKILD
IPC: F16H57/02
Filed: 1981-02-24
Abstract: The opening and closing device allows a simultaneous opening of roof flaps or the like of a length of, for example, 100 m. Gearwheels are permanently arranged at equal intervals in housings on a drive shaft extending tranversely. The gearwheels drive their associated rack for a simultaneous displacement of the entire window. The teeth of a gearwheel have a larger width and are relatively thin in comparison with the associated dimensions of the rack teeth. In order to ensure gearwheel engagement, the rack contains supporting faces which are in engagement with cylindrical faces of the gearwheel and of supporting rollers. This arrangement ensures that the racks, which are arranged in an articulated manner on the window frame, can be displaced along their points of engagement with the gearwheel or can be rotated about these points of engagement, without being disengaged from the gearwheel, this taking place in such a way that a pinching effect in conjunction with a longitudinal stretching or contraction of the drive shaft (caused by temperature fluctuations) is avoided. <IMAGE>

Title: Centrifugal driving clutch
Inventor: DUEPMEIER WILHELM
IPC: F16D43/18
Filed: 1981-03-25
Abstract: A centrifugal driving clutch can be disengaged against the action of centrifugal force by means of an axially movable switching body via an axial conical bore section (44, 46) and an axial, conical pin (48, 50). In order to reduce the axial dimensions, the stroke of the switching body (32) is selected to be smaller than or equal to the conical bore section (44, 46). Selection of the cone angle ensures that the centrifugal body (20, 22) is released and/or disengaged when this limited stroke is performed. <IMAGE>

Patent DE-3118084-A1 (DE)
Title: Device for braking packaging wrappers running off from a filling tube
Inventor: NIEDECKER HERBERT DIPL ING
IPC: A22C11/02
Filed: 1981-05-07
Abstract: In displaceable devices for braking packaging wrappers which run off from a filling tube of a filling machine and which, during the filling operation, pass through the orifice formed by the gathering and closing members of a closing machine combined with the filling machine, there is a problem, during the filling of such packaging wrappers which, when filled, have a substantially larger diameter than the said orifice, of ensuring that the packaging wrapper can expand to the final filling size only behind the closing machine in the filling direction. This problem is solved in that there is provided on the braking device (4), in the filling direction, a tubular extension (6) which, during the filling operation, projects into the orifice formed by the gathering and closing members. This also has the advantage that the packaging wrapper does not already fill in the region of the gathering or closing members or even in front of these, which would lead to higher friction and to the risk of damage during the filling operation. <IMAGE>

Title: Toggle for locking a plug-in unit
Inventor: RUETHER HUBERT DIPL ING
IPC: F16B12/42
Filed: 1981-05-20
Abstract: The invention relates to a toggle for locking a plug-in unit, having a rotary locking bar, a rotary head and a shaft connecting the two. In order to assemble four tubes, forming a planar rectangle, to provide a stable three-dimensional structure, 4 x 2 plug-in units, each having a toggle, are to be formed, the shaft axes of which can lie in the plane or can stand perpendicularly thereon. By means of a known toggle, a plate can be fixed only on a tube rectangle, that is to say it can only be fixed subsequently. In order optionally to be able to carry out this fixing procedure between the tubes of the rectangle, that is to say during its assembly, the invention proposes to provide the toggle, in principle, with a cavity in order to receive the edge of a plate loosely or in order to receive an element for fastening the plate on a plug-in unit. <IMAGE>

Title: Process for the biological purification of waste water
Inventor: DRNEVICH RAYMOND FRANCIS
IPC: C02F3/12
Filed: 1981-12-03
Abstract: The invention relates to a process for the biological purification of waste water by means of a waste water purification plant which has at least three tanks (1, 2, 3) connected together, in which aeration of waste water/activated sludge mixture is possible in all three tanks and in which, in various process steps, one of the tanks is used as clarifier with the aeration switched off. In order to achieve a purification efficiency which is as high and uniform as possible, in a first process step the inflowing waste water is distributed in two tanks and aerated in these (B). The waste water/activated sludge mixture flowing out of the aeration tanks is clarified in the third tank (K). After the activated sludge concentration in one of the tanks operated as aeration tank has fallen, in a second process step the waste water feed to this tank and the aeration in this tank are stopped, and the connection to the other tanks is broken (A). After the activated sludge in the switched-off tank has settled, the latter is operated in a third process step as clarifier (K), and the two other tanks are operated as aeration tanks (B). After the activated sludge concentration in one of the tanks now operated as aeration tank has fallen, in a fourth process step the procedure is repeated with respect to this tank. <IMAGE>

Title: Apparatus for thermoforming mouldings
Inventor: HARTNAGEL HATTO
IPC: B29C51/32
Filed: 1981-12-17
Abstract: In a thermoforming apparatus, which has in its mould a cutting stamp and at the same time a cutting plate opposite the latter, it is intended to make interacting cutting edges possible by special cooling measures. For this purpose, coolant channels are taken up to the vicinity of the cutting edges, although the cutting stamp bearing the one cutting edge is axially movable to a limited extent in a cooling block and the hold-down device, combining with the cutting plate to bound a coolant channel, is axially movable in the opening of the cutting plate. The coolant channels are therefore flanked on both sides by dynamic seals and, if appropriate, additionally also on one side by a leakage-water collecting channel. The dynamic seals may in this case be formed by sealing rings of cruciform cross-section. In particular, however, the escape of coolant from the coolant channels is prevented by the coolant being sucked through the coolant channels and thereby kept at an underpressure in relation to the atmospheric pressure prevailing around the thermoforming apparatus. For this purpose, the coolant is drawn off from a coolant collecting vessel in connection with the outside atmosphere, passed through the coolant channels and returned to the coolant collecting vessel by a coolant delivery apparatus, the coolant channels being connected to the suction side of this coolant delivery apparatus.

Title: Chain lock for load chains
Inventor: REMMEL JOCHEN DR
IPC: F16G15/04
Filed: 1981-12-17
Abstract: A chain lock for load chains, such as round-steel chains, consists of at least two parts which can be connected by means of pins and pockets corresponding to said pins such that the parts transmit force, the pins having a projecting pin head, arranged on a pin neck, and the pockets having internal contours matched thereto. While maintaining the same external dimensions, it is intended to vary the cross-sections of the pins and of the pocket walls in such a manner that the breaking strain of the connecting point is increased. To this end, the pin heads and the pin necks taper in the direction towards the free end of the respective pin, and the internal contours of the pockets taper in a corresponding manner towards their inner end side.
