Patent DE-4324568-A1 (DE)
Title: Cationic paper sizes
Inventor: ADLER PETER DR
IPC: D21H17/45
Filed: 1993-07-23
Abstract: The object was to develop cationic polymeric surface sizes (sizing agents) for paper having improved sizing capacity which do not separate out any of their constituents and thus do not impair papermaking. The problem is solved by 5 to 35% aqueous dispersions of     A terpolymers of     a) from 6 to 25% of dimethylaminoethyl methacrylate,   b) from 30 to 75% of styrene and   c) from 5 to 45% of acrylonitrile, and containing d) from 0.5 to 5% of PE wax oxidate which is partially in free-radical grafted form, or   B terpolymers as in A in which free-radical emulsion polymerisations of styrene and alkyl acrylates have been carried out, where from 20 to 30% of A has been converted into B   The dispersions have no tendency to separate out wax, so that undesired slipping does not occur in the paper sized on the surface therewith.

Patent DE-4331781-A1 (DE)
Title: Control device for a drive motor for moving an element, in particular a garage door, guided along a specific path between two end positions
Inventor: BOLZ PETER
IPC: E05F15/668
Filed: 1993-09-18
Abstract: A control device is proposed for a drive motor (14) for moving an element, in particular a garage door, guided along a specific path between two end positions. A position sensor (21) on the track is used to generate a position reference signal. A rotary encoder (15) connected to the drive motor (14) supplies counting signals for a counting device (27). The position sensor (20) can be positioned at one of the end positions, a position signal from this position sensor (20) stopping the drive motor (14) and applying a first counter state, which can be fixed, to the counting device (27). The second counter state, reached on driving to the second end position, is transferred into a memory device (28) by actuating an operating element (22). In each case on reaching the stored second counter state, the drive motor (14) is stopped by means of a comparison device (29). By this means, only one of the end positions needs to be stored electronically, and the element which is guided along the path can be coupled to this path in any desired manner and nevertheless reliably attains the end position provided with the position sensor. <IMAGE>

Title: Spinning mill installation - utilises warning techniques applicable to block doffing system
Inventor: MEYER URS ANDREAS DR
IPC: D01H9/00
Filed: 1993-09-28
Abstract: A process to run a spinning mill, consists of a group of machines which require doffing on the block system. Each machine in the group has a predetermined block doffing time. The appts. used is also claimed. Typically, the machines may have a central control system with a counter and visual display, equipped with a programmed memory and arranged so that the doffing at each stage is staggered. This avoids personnel being called to more than one position at a time in their area. It also prevents overloading of inter-transport systems. The control has a programmed device to synchronise the times of block doffing. This is calculated to allow for measured length of material on the cops, bobbins, etc., and consideration has to be taken of the shift system of the personnel. This has also to allow for mechanism which results in some level of automation.

Title: Device automatically delivering media or the like
Inventor: POPPE ENGELBERT
IPC: F16N11/04
Filed: 1994-02-21
Abstract: This device, in contrast to drives which are known in the prior art for these devices and in which the device is started electrochemically by the generation of gas, is designed as a mechanical drive. The mechanical drive is characterised in that, upon start-up of the device by means of opening the closure at the outlet connection piece, the mechanical force in the drive unit automatically moves a piston with which the medium or the like is forced out of the container. The advantage of the mechanical drive first of all lies in the simpler manipulation upon start-up of the device but in particular in the disposal, for the drives corresponding to the prior art are very harmful to the environment and from now on require separate disposal, whereas in a mechanical drive the disposal of polluting substances is dispensed with. Fields of application are, for example, lubricating points or all locations where a certain medium has to be delivered within a certain period.
Patent DE-4406763-A1 (DE)
Title: Toothed wheel with integrated piston
Inventor: SCHMIDT EDWIN
IPC: F16H55/17
Filed: 1994-03-02
Abstract: A toothed wheel with an integrated piston, which is installed as a drive element on the drive shaft, leading outwards, of bodies rotating on the outside of free housings. The intention of the invention is to compensate the reaction torque which is primarily produced by the friction moment on the bodies rotating on the outside and produces a rotary reaction effect on the housing. In the case of helicopters, in addition to the main rotor a vertical tail rotor is installed for this purpose on a body extension, which tail rotor produces an outer counter-torque with lever action up to a state of equilibrium. In the case of the invention, the engagement, due to rotation, of the teeth of the output drive element in the engagement regions of the input drive element is made more difficult by means of hydraulically reinforced piston pressure, and thus the otherwise easier way of partial reaction rotation of the output drive element on the input drive element is prevented. The reaction torque, thus controlled, is already compensated at the point of origin. The application is suitable for the drive shafts of screws on floating equipment, of wheels on vehicles and, in particular, of the main rotors of helicopters.

Inventor: YUEKSEL LEVENT DR
IPC: B01D53/00
Filed: 1994-03-28
Abstract: In the method proposed, the exhaust gases arising from the drying of products containing volatile constituents are cooled, the condensate thus obtained is subjected to cross-flow membrane filtration and part of the purified exhaust gases fed back to the drying process. The concentrate obtained is recycled in such a way that the substances in it can be re-used, to produce thermal energy, or in some other way. The effective and economic method is suitable for use in disposing of aerosols, in particular organic aerosols, in the exhaust gases.

Title: Controlling load of telecommunication network during heavy demand for certain destinations
Inventor: DANIEL HANS GEORG
IPC: H04Q3/00
Filed: 1994-04-21
Abstract: The control procedure is applied during mass calls to given targets. At each exchange junction (A-E) of the network, the ratio of starting, successful call attempts to a total number of call attempts w.r.t. all combinations of a part of regionally defined communication type, concerning the total of dialling numbers is determined. When a given, low ratio value and a predetermined min. number of engagement attempts are not attained, the respective number combinations are stored. The stored numbers are supplemented by a further part of the dialling number total and the above steps are repeated. If one or more complete dialling numbers are determined, coinciding with the criteria of the low demand mode, calls to the target members are delayed.

Title: Separation and recovery of harmful materials e.g. poly:chlorinated bi:phenyl(s) from capacitors
Inventor: BOEHME HENDRIK DR
IPC: B08B3/08
Filed: 1994-08-11
Abstract: The capacitors to be processed are fed to a mechanical crusher (1), with the resulting particles falling onto a conveyor (2) to be transported through a cleaning chamber (3) that contains a solvent (5a), pref. methyl-ethyl-ketone or tetrachloromethane. The fluid is chosen to have a boiling point less than 150 deg C. and a density lower than that of the metal particles and higher than that of the non-metallic parts, such that the metallic particles are separated and fall to the bottom. The cleaning effect is enhanced by application of ultrasonic energy (12). The remaining material passes to a second stage where the liquid is heated and evaporates off the particles which pass to a collector (11). The vapour condenses (7) and returns to the bottom.
