Title: Method for the definitive disposal of waste
Inventor: HELIN STIG-AKE
IPC: B09B3/00
Filed: 1988-11-02
Abstract: The method for the definitive disposal and distribution of waste, in particular domestic waste, comprises the presorting of the waste into organic waste, waste to be deposited and reusable waste. The organic waste and the waste to be deposited are comminuted in separate operations and mixed to form a pumpable mass by addition of a liquid. Waste, in other words waste water, sewage sludge or similar, can again be used as the liquid, and additives are added to the pumpable mass to control the fermentation process or to avoid smell nuisance and to suppress pathogens. The pumpable mass is conveyed to seaport installations in bulk transport means, such as tankers and pipelines and transported by means of these devices to regions where they are used or distributed in suitable manner. The definitive deposition takes place in earth regions which are today infertile and the prepared waste is used for improving the earth.

Title: Compressed air drive device for a current collector
Inventor: GRONDINGER GUENTER ING
IPC: B60L5/32
Filed: 1989-02-02
Abstract: Compressed air drives for current collectors advantageously have in the pressure line (6) leading to the lifting cylinder or lifting bellows (7) a pressure control system (8) consisting of a pressure control valve (9) and a throttle valve (10). However, disadvantages are produced by the interaction with the quick-acting venting valve usually used. By means of the elements of the pressure control system (8) the venting of the pressure line (6) required to lower the current collector (3) is throttled and as a result delayed. Therefore, according to the invention instead of a quick-acting venting valve a valve (11) which can be activated pneumatically via its own actuation line (15) is provided, the actuation line (15) of which valve (11) is connected to the pressure line (6) upstream of the pressure control system (8). <IMAGE>

Filed: 1989-06-22
Abstract: 2.1 When recording with video cameras or during the subsequent processing of video films using video recorders, the user is also to be given the opportunity of changing the image content, that is to say of achieving pictorial effects. The pictorial effects most frequently used include the fading-in and fading-out of images or scenes and the cross-fading from one scene to another, or the generation of colour effects. It is the object of the invention, to specify an arrangement which meets the abovementioned requirements and, in addition, is of simple design so that its use is not only restricted to professional devices. 2.2 According to the invention, this is achieved by the fact that a luminance signal or a chrominance signal which is present in digitised form, is compared in a comparator with a grey value or a colour saturation value, respectively, and one of the two signals is switched through as a function of the desired pictorial effect. To achieve transitions, the grey value or the colour saturation value is predetermined by means of a counter, the direction of counting and speed of counting of which can be predetermined. 2.3 Video device. <IMAGE>

Title: Method for continuous adjustment of the output voltage of a self-commutated DC voltage intermediate-circuit converter
Inventor: NIESEL NORBERT ING GRAD
IPC: H02M5/451
Filed: 1989-06-22
Abstract: It is intended to specify a control method for an intermediate-circuit voltage converter (1, 2, 3) whose invertor (3) is operated in a pulsed manner at low frequencies by a controller irrespective of a voltage reference variable (wUS) and a frequency reference variable ( omega S), and is operated in an unpulsed manner at a constant intermediate-circuit voltage (UD) at high frequencies. To this end, a controllable mains power supply converter (1) is connected to a mains power supply having a constant voltage (UN) and frequency (f). The control signals (GRSt) for the mains power supply converter (1) are obtained from a voltage regulator. The intermediate-circuit voltage (UD) is used as the control variable for the voltage regulator. At least one minimum voltage reference variable (UDMIN) is always provided as the reference variable for the voltage regulator. In the case of a predetermined voltage reference variable which is equal to or greater than the minimum voltage reference variable (UDMIN), the drive level A of the controller of the invertor (3) is set to 1 and then an additional reference variable ( DELTA UD) which is proportional to the difference between the voltage reference variable and the invertor output voltage (US) corresponding to the drive level 1 at the minimum intermediate-circuit voltage (UDMIN) is given to the voltage regulator (4) which regulates the intermediate-circuit voltage (UD). <IMAGE>

Title: Three=dimensional item production method - bends bars after heating initially in common plane at different points
Inventor: BATORI GYOERGY
IPC: B21D11/10
Filed: 1989-12-27
Abstract: The method produces items bent in three dimensions from bar stock, particularly spring clips holding track rails in position.  A blank of the necessary length is delivered from a magazine into the position where it is heated to shaping temp. after which a manipulator passes it to a station where it is gripped and bent in succession by tools acting in straight lines in a common plane. A second manipulator then transfers it to a die forming a negative of the finished article, and to which it is clamped. As the die is turned, the blank is pressed into the channels in it by a roller. The die is then locked to prevent it turning further.  Tools working in straight lines at the necessary angles press the remaining portions into the deepest recess in the die.  After they and the roller have been retracted, ejectors in the die separate the finished article from it. ADVANTAGE - Low cost and constant quality, utilising material readily available.

Title: Cultivating cells and their biological prods. with fermenter - and controlled membrane sepn. of unwanted components
Inventor: NAKANO RYUSEI
IPC: C12N5/02
Filed: 1990-02-01
Abstract: Prior to return to a fermenter, cells cultivated in a  broth are sepd. by a hydrophobic membrane, made e.g. of hollow fibres and sterilisable by steam. The membrane is suitable for materials of specific molecular wt. ranges. While waste prods. are similarly removed, together with materials which could impede cell growth, one or more medium components of a useful substance produced by the cell and whose molecular wt. is less than that of the medium component(s), are similarly removed and returned to the fermenter. These include expensive high molecular wt. medium components of sera, whose return facilitates high density cell cultivation to reduce operating costs. Between upper and lower ends of a container, cultivation is accelerated by the intensive mixing derived by internal jets delivering fast gas streams, without damaging cells. USE/ADVANTAGE - Produces wide range of useful prods., e.g. Interferon, enzymes, and immunoglobin in economically desirable amts.

Filed: 1990-04-20
Abstract: A dilatation catheter (1) for reducing or eliminating vascular constrictions or vascular occlusions (2) has at its distal end at least one pressure element (3) and, possibly, also a second pressure element (16) which is spaced apart from the first pressure element (3). The pressure element or pressure elements are used to exert a pressure on the constricted vessel wall in order to force back deposits which are present there and in this way to once again enlarge the inner lumen of the vessel (4). For this purpose the catheter (1) is mounted rotatably and can be connected at the proximal end to a rotational drive mechanism (5). In order to be able to produce inside a vessel (4) a greater circumference or cross-section than is predetermined by the pressure element(s) (3 and/or 16), the catheter (1) has an inner guide channel (6) for a stylet (7) and is flexible near the pressure elements (3 and 16) so that it can be bent or deflected. Near its end (8) projecting in the use position up to or into the pressure elements (3) or the pressure elements (16), the stylet has as a supporting and guiding means a first bend or curve (9) and can in turn be coupled to a rotational drive mechanism (5) and can in this way be driven in rotation, preferably in synchronism with the catheter (1) so that the pressure element or pressure elements are moved not only about their own axis, but at the same time eccentrically in a circular orbit. <IMAGE>
