Abstract: In a drive for a punch-side ejector slideably mounted in a ram (6) of a mechanical forming press and having a bent lever (15) which is swivellably mounted in the ram (6), one limb (14) of which acts on that end of the ejector which faces away from the punch and the other limb of which is in drive connection with a link (17) which is articulated on a driving connecting rod (5) for the ram (6) and transmits driving movements cyclically to the bent lever (15), the object is to avoid linear contacts in the drive connection and to make possible adaptation to different heights of the die and punch. The solution consists in designing the drive connection as far as possible as a link chain, the link (17) articulated on the driving connecting rod lying approximately at right angles to the direction of motion of the ram (6) and that arm of a two-armed lever (19) which is articulated on the said link extending approximately parallel to the direction of motion of the ram (6).

Abstract: In the MS-MS flight time mass spectrometer, a local focus of the ion source is determined with a second order correction. With suitable selection of the geometrical and electrical variables of the ion source, this local focus is created such that a very good primary mass resolution is possible therein if suitable methods for secondary access are selected. …<??>The secondary access to the local focus takes place… a) in the form of a focused, pulsed laser beam or other pulsed access methods which can be focused,… b) in the form of a meshed network of very fine "line combs", engaging in one another, to which voltage pulses can be applied,… c) in the form of a combination of a) and/or b) with an electrostatically elevated, primary drift path which is free of fields. …<??>The MS-MS flight time mass spectrometer is operated with a reflector mirror which is provided with a moving reflector end plate with a voltage which can be readjusted, and makes possible elimination of primary ions from the spectrum without any loss of mass resolution. As a result of suitable matching of the reflector fields and suitable selection of an observation window in the flight time spectrum, a secondary mass spectrum generated in the local focus can be measured. …<IMAGE>…

Abstract: The present invention concerns a procedure for preparing a solid procatalyst composition of a catalyst system in­tended for polymerizing olefins, in which procedure the magnesium halide is dissolved and/or combined with an elec­tron donor and treated with a transition metal compound. The invention also concerns said procatalyst composition and its use together with the cocatalyst for polymerizing olefins. The procedures known of prior art include the treatment of an at least to some extent crystalline mag­nesium chloride, which, with respect of the catalyst activi­ty, is unfavourable, with an electron donor and a transition metal compound, or, thereafter, the preparation of a solid reaction product of the three components of the procatalyst composition from a solution, whereby also activity decrea­sing crystallinity is produced. In the present instance, it has been possible to increase the activity of the cata­lyst component by impregnating with electron donor solutions of the magnesium halide a separate carrier from which an excess of the electron donor is removed before the treatment with a transition metal compound. The separate carrier is advantageously silicon dioxide, an advantageous magnesium halide of magnesium chloride and an advantageous electron donor of a C₁-C₁₀ alkyl ester of an aliphatic carboxyl acid, such as ethyl acetate. An alpha-olefin, such as polyethyle­ne, is polymerized with said procatalyst and e.g. with a trialkyl aluminium cocatalyst, either in one step into a polymer having a narrow molecular weight distribution, or in two or several steps into a polymer having a bimodal or wide molecular weight distribution.

Abstract: A connection assembly in which the ends of two flat cables overlap each other with bared conductive layers thereon held in resilient engagement with each other by a connector. At lest one of the flat cables is capable of being withdrawn laterally from the connector. Offset polarising pins in the connector extend through different length slots in the movable flat cable. The slots open at the end of the cable so that when the cable is withdrawn from the connector, the cable will not be torn, or resist withdrawal of the cable from the connector. A conductive shielding bead is formed on the opposed surfaces of the two halves of the connector around the contacting regions of the cables An insulative flap is formed over the bared conductive layers on the movable cable which prevents such layers from engaging the shielding bead when the cable is withdrawn from the connector.

Abstract: The present invention relates to a fan speed controller which may be used in conjunction with heating, cooling and dehumidification air ventilation systems. The fan speed controller regulates ambient temperature and humidity by maintaining constant temperature differentials across the heating and cooling elements of the system. These temperature differentials are repeatedly tested and maintained through a feedback control system which regulates the volume and velocity of air passing through the heating and cooling units by regulating the speed of the fan circulating air through those heating and cooling units.

Abstract: A method is described for utilising at least components of a flue gas produced during an incineration. In order to make available the cheapest possible sources of raw materials and simultaneously reduce the environmental pollution, it is proposed that hydrocarbon-containing and/or carbon-containing materials, such as for example waste plastics, are incinerated and that the carbon dioxide and/or carbon monoxide produced in the incineration, and also steam-containing flue gases, are used, after cooling and purification if required, for the synthesis of hydrocarbons. However, they can also be converted into hydrocarbons. However, it is also possible to react at least a part of the carbon dioxide contained in the flue gases and the water contained therein with ammonia to give urea.

Abstract: A semiconductor circuit device which has a first stage logic circuit (INV₁) for receiving an external input signal and a plurality of inverters (INV₂, INV₃, ...) for forwarding an output signal from said first stage logic circuit (INV₁) to a succeeding stage and which is to become active when an activating signal (OE; SE1) is active. The device includes a threshold value correcting circuit (TVCC) formed by a threshold value correcting inverter (Q₁, Q₄) and a switching circuit (Q₂, Q₃). The switching circuit (Q₂, Q₃) connects an output terminal of the threshold value correcting inverter (Q₁, Q₄) to an output terminal of the first stage logic circuit (INV₁) only during the period in which the activating signal (OE; SE1) is in its active state. By having the threshold value correcting circuit operate synchronously with the activating signal, the input threshold level of the first stage logic circuit (IMV₁) is corrected in accordance with the external input signal level in case there is a change in the power supply potential V cc  and the ground potential GND within the semiconductor chip and this ensures the proper operation of the first stage circuit (IMV₁).
