Title: Arrangement for protecting voltage-limited electronic modules against over-heating and over-voltage
IPC: H02H7/18
Filed: 1996-04-21
Abstract: The arrangement has a series circuit of at least one voltage limiting element (1) and a temperature sensitive switch element (2) with at least a first and second terminal. When the operating temperature is normal, the temperature sensitive element (2) forms a current connection. When a predetermined temperature is exceeded the temperature sensitive element (2) forms a current restriction. The electronic circuit to be protected is connected to the connection point between the voltage limiting element (1) and the temperature sensitive element (2). A heat conductive connection is provided between the voltage limiting element and the temperature sensitive switch element. The heat conductive connection (9) is formed such that the connection point (7) of the voltage limiting element forms the first terminal (8) of the temperature sensitive element (2). The second terminal is formed of an electrically conductive spring (2). The current connection between the first and second terminal is formed by a solder bath (10). The melting temperature of this corresponds to the predetermined temperature to trigger the current restriction. The spring (2) has a tensioning force which withdraws the solder side of the second terminal of the temperature sensitive element (2) from the connection point of the voltage limiting element (5,7,8) when the solder bath has reached its melting temperature.

Title: Appts. for detecting physical parameter to control sensor element to output electric signal esp. for acceleration sensor
Inventor: NONOYAMA SHIGERU
IPC: G01D5/24
Filed: 1996-04-24
Abstract: The physical parameter detector has a sensor e.g. variable capacitor element (16) which is activated by a supply voltage (VDD). On agreement with a predetermined physical parameter, the sensor element outputs an electric signal. An analogue to digital convertor (20) digitises the electric signal and outputs digital data. A control device (22) calculates a control parameter from the digital data to control the sensor element when the electric signal is adjusted to a predetermined output signal. The control device also generates a control signal in accordance with the control parameter. An activation device (48) activates the sensor element in accordance with the control signal, via a switching arrangement (18). The control device outputs, in accordance with the control parameter or the control signal, a detection signal which displays a physical parameter.

Title: Water treatment adsorption agent regenerated in situ
IPC: B01J20/34
Filed: 1996-04-27
Abstract: The novelty is that in a process and assembly (a) an adsorption agent bearing a load of impurities is regenerated by a retro-fitted cleaning and decontamination assembly (b) the retro-fit assembly facilitates the in-situ regeneration of the adsorption agent; (c) in-situ regeneration prevents damage that might otherwise occur during transport of the agent to a treatment installation; and (d) the regeneration takes place within the reactor in which the adsorption agent treats water (e.g. ground water, waste water, process water), in normal operation.  Preferably (e) the regeneration process uses electrolysis generating hydrogen at the cathode, the gas being surrendered to microorganisms; (f) the cathode is surrounded by an ion-exchange membrane from the rest of the reaction vessel, and discharging the gas to a reactor outlet pipe (g) the specific choice of membrane at the reactor outlet prevents the ingress of microorganisms from the reaction vessel into the pipes and the mixing vessel, during cleaning and decontamination operations; (h) as soon as the adsorption agent is fully laden, cleaning and decontamination commences by creating conditions within the reactor which enable the microorganisms to convert the load (without heavy metals) into minerals.

The height equalisation of the settled stretch is carried out in accordance with each step of the equalisation height of the section.
Patent DE-19625824-A1 (DE)
Inventor: NYGREN LOVISA M M
IPC: D21H21/16
Filed: 1996-06-28
Abstract: A process for making paper products is described in which sizing is effected by use of a hydrophobic cellulose-reactive sizing agent in combination with a promoter. As promoters water-insoluble bases are used which are formed by the reaction of saturated fatty acids, unsaturated fatty acids, hydroxy substituted fatty acids and/or mixtures thereof and alkanoldimaines and/or aliphatic polymaines. Further a corresponding paper sizing composition is described which comprises a hydrophobic cellulose-reactive sizing agent and such a promoter. The combination of hydrophobic celluulose-reactive sizing agent and promoter provides a synergistic effect so that for achieving the same sizing level a lower amount of hydrophobic cellulose-reactive sizing agent is required. Alternatively at the same concentration of the hydrophobic cellulose-reactive sizing agent a higher sizing level can be achieved.
Patent DE-19627675-A1 (DE)
Title: Deep-drawing hollow objects, especially containers having large bodies and smaller necks
Inventor: LAUERMANN WALTER
IPC: B29C51/04
Filed: 1996-07-10
Abstract: This novel method forms hollow objects, especially containers, by deep drawing. The feedstock is an individual- or sheet blank material (2). This is softened above the matrix containing the mould chamber (15) corresponding to the final shape. Force is exerted on the blank, to press it into and against the walls of the mould chamber. The novel feature of this process is an initial preforming stage. The plasticised blank is made into a cup-, pouch- and/or tub-shaped preform (10). Maximum expansion, parallel to the base, is limited to allow introduction of the preform into the mould chamber.  Also claimed are the equipment required for the process and the corresponding preforming tool. Preferably the preform is long and its width is less than the minimum, open internal width (26) of the moulding chamber. Before preforming, a intermediate preform is produced. This tapers to the base region (57), having a pouch-, cup-, hollow conical- or other similar shape. The preforming tool (4) brings the blank to conform or rest against its wall and is then retracted. Applied differential pressure assists release. A preforming plunger (14) deepens the blank, pressing it into the chamber. Heating keeps the preform in the plasticised state. Not until during or after the moulding stage, is the connection of the object with the residual blank severed (17). Annular heating may be applied to the blank, especially towards the outer edges of the intermediate preform. A stage of cooling may follow the preforming stage, to hold the shape produced.
