Abstract: In a method for producing hollow articles from thermoplastic material, a tube-like preform is formed by discharge from a die gap of an extrusion head and inflated in a blow mould. Furthermore, the position of the preform with respect to the blow mould is adjusted by open-loop and/or closed-loop control and finally the flash produced by the blow mould is separated from the article once it has left the blow mould. 
<??>In order on the one hand to achieve a correct position of the preform in critical cross-sectional areas with respect to the blow mould and on the other hand to achieve a correct weight of the hollow article to be produced, it is proposed that for controlling the position of the preform in accumulator head operation the weight of the cut-off bottom flash and/or the net weight of the hollow article be measured and, depending on a weight discrepancy in comparison with a set value, that the die gap be altered, and in continuous extruder head operation that either the net weight of the hollow article and the weight of the bottom flash be measured and compared with set values or the net weight of the hollow article and the position of marks in relation to particularly critical cross-sectional areas be compared with predetermined set values and the positional control derived therefrom.

Abstract: In a stop and regulating valve with a housing which has at least one axial inlet port and one radial outlet port and can be inserted into fittings and in which is non-rotatably mounted transversely relative to the longitudinal axis a valve-seat disc against which a valve-regulating disc rotatable by means of a valve spindle bears on the upstream side, the valve-regulating disc being tautened against the valve-seat disc by means of a spring, the two valve discs being insertable into the housing from an upstream inlet port, and a sealing element being provided between the inflow channel of the fitting and the housing, for improvement and simplification it is proposed that the housing should have, in the bottom of the inlet port, at least one outer supporting shoulder in the region of the housing wall and an inner supporting shoulder in the region of the passage orifice of the valve spindle and that the spring be connected to the valve-regulating disc and the housing via the valve spindle.

Abstract: A sensing assembly suitable for detecting both a first event which involves the presence of an electrolyte and a second event which does not involve the presence of an electrolyte, and for distinguishing between them. The assembly comprises a first conductor and a second conductor which is electrically insulated from the first conductor in the absence of both first and second events but becomes electrically connected to the first conductor by either an ionic connection in the presence of a first event or an electronic connection in the presence of a second event. The assembly also comprises a sensing apparatus of determining whether the connection is ionic or electronic. The assembly is useful for detecting leaks of hydrocarbons, e.g. gasoline, and water in storage tanks.

Title: Control device for the closure sequence of double-wing doors
IPC: E05F5/12
Filed: 1990-02-28
Granted: 1993-07-14
Abstract: When two swivel wings closing a wall aperture or the like are equipped with rebates (6, 7), a complete closure of the two wings can be obtained only when a specific closing sequence is adhered to. Where a passage wing (1) and a standing wing (2) are concerned, in principle the standing wing has to be closed before the passage wing can be closed. It is possible, however, to keep the passage wing in a particular opening position until the opened standing wing has been swung past it in the closing direction. This opening position of the passage wing is secured automatically by means of a blocking device (24) when the standing wing (2) is in an opening position, and it is unimportant how far it is opened. A closing-sequence control consists of a catch mechanism assignable to the door closer (10) of the passage wing (1) and of a release mechanism assignable to the door closer (11) of the standing wing (2), these mechanisms being coupled purely mechanically to one another via a tension member (37). <IMAGE>

Title: Device for measuring the turbidity of smoke and preferred application
IPC: G01N21/53
Filed: 1990-03-02
Granted: 1992-09-16
Abstract: The device comprises means (V, SLH, HE, LK) for producing at least one flushing airflow (SL; SL1, SL2) which flows around at least the surface region (FF) through which the test jet (MS) passes. This flow takes place over the reflecting and receiving device (MSK, SO; MEK, EO) for producing and evaluating a test jet (MS) and is directed in all cases from the edge towards the centre (OA). This prevents contamination of the surface region. According to a preferred embodiment, said means comprise in each case an air-guiding cap (LK), an air-guiding sleeve (SLH), preferably enlarged to form a funnel at one end (HE) and an oppositely situated fan (V) in a test transmitting head (MSK) or a test receiving head (MEK) of a measuring device preferably employing the subflow principle. The device is particularly suitable for measuring the particle emission in the exhaust gases of internal combustion engines, in particular those employing the diesel principle. <IMAGE>

Abstract: Bow-shaped soldering tips made of ceramic are used in the reflow soldering of electronic components having a multiplicity of connecting legs. The process heat is provided via electrical resistance heating, where hitherto the resistors were integrated in the bow-shaped soldering tip or constituted it themselves. The invention describes a bow-shaped soldering tip made of ceramic, the supporting part of which is a ceramic substrate (1) which is of planar design and is a good conductor of heat. To heat the soldering tip, electric resistors (2) are applied in a planar manner in direct proximity to the soldering edge (3). The resistors (2) are produced either by thin-film or thick-film technology. Thus, on the one hand, the soldering edge (3) is electrically non-conductive due to the use of ceramic and, on the other hand, the conduction of heat between resistor (2) and soldering edge (3) is not impaired due to a material which is a good conductor.

Abstract: A CMOS push-pull output buffer is powered by a low-voltage (e.g., +3.3 V) supply, but is able to withstand elevation of its output node to higher voltage without sinking large currents into the low-voltage supply. Thus, this buffer is able to operate tied to a bus that has various higher-voltage sources also operating on the bus. The P-channel pull-up transistor (11) of this buffer has another P-channel transistor (23) connecting its gate to the output node so that this gate will follow the voltage of the output node and thus keep the pull-up (11) transistor from conducting from the output node to the power supply (VDD3). The inverter (15) which drives this gate of the P-channel pull-up transistor (11) is also protected from reverse current into its low-voltage power supply by a series N-channel transistor (12) which will exhibit body effect and is sized to present a significant resistance.
