Patent DE-3028334-A1 (DE)
Inventor: BLUETHGEN BJOERN
IPC: G11B5/02
Filed: 1980-07-25
Abstract: A method is proposed for eliminating or suppressing unwanted acoustic signals in audio programs to be edited for reproduction in studios, in which the perceived disrupted segments in the signal are determined with respect to their time positions, and the signal ends having signal flow/polarity changes adjacent to the disrupted signal location are bridged by a transfer function, preferably in the shape of a semi-sine. The semi-sine is stored in the form of sampling values in an addressable read-only memory and can be read therefrom. In order to generate the desired transfer function, the signals read from the read only memory are uniformly distributed over the transfer function in accordance with the plurality of sampling values to be replaced across the width of the disrupted segment, the read signals being weighted in accordance with the margin conditions of the signal ends adjacent to the disrupted segment and being inserted in the proper sequence into the signal in the area of the original disrupted segment upon consideration of the direction of signal change.

Title: Hot embossing foil applied esp. to spray cans - with can heated in application zone then cooled
IPC: B44C1/17
Filed: 1980-07-30
Abstract: Metal objects are decorated by applying a hot-embossing foil with a heat-activated adhesive onto them with thermal action, by means of a pressing roller, plunger etc. The metal object which is to be decorated is itself heated in the contact zone and subsequently cooled. Pref. the roller or plunger applying the pressure is not heated. More specifically, the metal object is mounted on a thermally conducting support element so that the contract surface between them is at 90-130 (115)deg.C. Used for decorating cylindrical spray cans with hot- embossing foil. Whereas previously the difficulty of bonding due to the thermal conductivity of the metal can rendered this process very difficult, the heat is now applied to the can itself, and is not applied by the pressing roller.

Title: Full water desalination by preliminary water-softening - using weakly acid cation exchanger that is regenerated with simultaneous waste water neutralisation (CS 31.3.81)
Inventor: KADLEC VACLAV DIPL ING
IPC: B01J39/05
Filed: 1980-12-09
Abstract: In full water desalination with simultaneous neutralisation of water from ion exchange regeneration, the water is freed from Ca- and Mg-ions, before actual full desalination, in a water-softening step. A weakly acidic cation exchanger having -COOH functional gps. in Na form is used, opt. combined with a strongly acidic cation exchanger having -SO3H functional gps. in Na form. When exhausted, the softening step exchangers are regenerated in 2 steps; first with acid waste waters from the full desalination plant cation exchange step regeneration, and then with alkaline waste waters from the full desalination plant anion exchanger step regeneration. The process is used in feed water conditioning for high-pressure tanks. Useful cation exchanger vol. capacity is increased. Investment costs for neutralisation are reduced because the capacious neutralisation vessels are replaced by a cation softening step functioning in the full desalination plant.

Patent DE-3115387-A1 (DE)
Title: Central-locking system for doors and/or flaps of a motor vehicle
Inventor: KRUEGENER ROLF DIPL ING
IPC: E05B77/50
Filed: 1981-04-16
Abstract: The invention relates to a central-locking system (CLS) for doors and/or flaps of a motor vehicle, the locks of which have a rotary latch, with two catch recesses located one behind the other, and a detent pawl. Each lock is assigned an opening handle for lifting the detent pawl and a transmission linkage of interruptable force flux, leading to the latter, the locking of the lock taking place as a result of an interruption of the force flux and its unlocking taking place as a result of a closing of the force flux. In the lock provided with the central locking point, this is carried out inter alia by key actuation, whilst, in the other locks, remotely triggerable servomotors are provided for this purpose. A likewise centrally actuable anti-theft protection system is to be combined with the central locking system. For this purpose, each rotary latch is assigned a further detent pawl which engages with play into the front catch recess. These detent pawls can be lifted only by means of key actuation, if appropriate via remotely triggerable servomotors. The servomotors of the anti-theft protection system and their supply leads are separate from those of the central locking system. Means for precedence reversal are provided in order to avoid faulty switchings and operating faults, so that the anti-theft protection system responds first during closing and the central locking system responds first during opening.

Title: Device on seals, e.g. for the shafts in centrifugal pumps
Inventor: ALGERS BENGT
IPC: B01F15/00
Filed: 1981-09-22
Abstract: Device on, for example, a centrifugal pump for keeping particles suspended in a liquid away from a seal (18, 20), preferably of the plane face type, mounted between a housing (12) containing the liquid and a rotating shaft (10) passing through the latter. An intermediate wall (24) is placed between a non-rotating wall surface (16) and a shaft part rotating in the liquid and this intermediate wall is designed with at least one outer opening (36) and one inner opening (34), adjacent to the intermediate wall and to the shaft part respectively. These openings are connected to one another via a clear space (28) in front of the sealing faces (22; 48) such that the liquid set in rotation by the shaft or elements seated on the latter is induced to flow in the axial direction through one of these openings from the liquid space of the housing to the clear space and back to the liquid space through the other opening (36), taking along with it any particles in the clear space. <IMAGE>
Patent DE-3143934-A1 (DE)
Title: Holding and braking device for the superstructure of bridges
IPC: E01D21/06
Filed: 1981-11-05
Abstract: Reinforced concrete bridges, which are produced by timed shifting, have to be held or braked between the shifting operations and in emergencies. For technical and cost reasons, the installations for this must be small and require little operating expenditure. The brake calliper described below is very small compared with equipment using bars or ropes and requires no operating expenditure. In rigid concrete bridges it is possible, by lifting, to generate additional reaction forces and hence increase the brake friction. The calliper consists of two wedges set against one another and pressed against one another by a spring in such a way that the overall height increases. The spring force is taken up first by a cylinder pressurised by oil under pressure. In an emergency, the oil can be let out. Consequently, the spring can become active and actuate the wedge. Brake actuation is thus also possible in the event of a power failure. The enclosed drawing shows the construction in principle. <IMAGE>

Patent DE-3205641-A1 (DE)
Inventor: WEIHRAUCH GEORG
IPC: A46D1/00
Filed: 1982-02-17
Abstract: In a process for producing bristle tuft material or separate bristles of plastic or synthetic resin for making sweeping brushes, brooms or housepainters' and artists' brushes, endless monofilaments are extruded and then directly wound on a bobbin or guided together in the form of tow, such tow then being twisted and cross wound onto a bobbin without end flanges so that, for a given diameter or size of bobbin, the material is less sharply bent, and will be less permanently curled when taken off the bobbin. Furthermore it is possible for a much greater length of endless monofilament material to be put in a single package so that less of the weight of such a package is made up by the weight of the bobbin. From the point of view of production engineering, there is the useful effect that the monofilaments or the twisted tow may be run off parallel to the axis of the cross wound package and the drawing off part of the brush making machine made of simpler design.

Title: Arrangement with a pulsation damper
Inventor: ANDERS CHRISTIAN
IPC: F04B11/00
Filed: 1982-03-13
Abstract: The invention relates to an arrangement with a pulsation damper and a pump, in particular a positive displacement pump, pulsations in the fluid pumped by the pump being damped by means of the pulsation damper. In arrangements of this kind, particular difficulties arise as regards a functionally reliable and maintenance-free connection of the pulsation damper and the pump. Special mention may be made of welded joints in this region, which, due to the safety requirements customary nowadays, particularly in the power station sector, have to be checked regularly. The invention therefore proposes that the housing of the pulsation damper be connected directly to a component, in particular the valve body, of the pump and that the said component form a pressure-bearing closure part for the interior of the pulsation damper. <IMAGE>
