Patent DE-2855281-A1 (DE)
Title: High temp. gas filtration element support - by bonding to gas permeable support material
Inventor: WEBER EKKEHARD PROF DR ING
IPC: B01D46/00
Filed: 1978-12-21
Abstract: Filter material for gases at temp >600 degrees C and high pressure consists of tissue or fibre mats, based on glass fibres or their combination with alumina and other cpds. These are sensitive to snapping, esp when the filter undergoes a backflushing cycle, if not firmly supported. It is suggested to support this filter material on both sides by point or large-area boding by temperature-resistant anorganic adhesives to a supporting material which is permeable to gas and offers a low resistance to flow. The preferred materials have a ceramic basis. This prevents the premature deterioration and ultimate failur eof such filter materials.

Title: Constant DC voltage regulator - combines series and switching stages with reference voltage provided by resistor and Zener diode
Inventor: BUDNIK NORBERT ING GRAD
IPC: H02M1/15
Filed: 1979-02-08
Abstract: A constant voltage regulator combines series and switching stages to avoid problems during the transiet stage following switch on. The reference voltage (Vdi) is provided by a resistor (R1) and Zener diode (D1) and is applied ove a resistor (R4) to the base of a drive transistor (T52) for comparison with the output voltage (Ua). The transistor controls the base of a regulating transistor (Ts1) with the collector emitter path connected between supply (Ue) and output (Ua). The regulating transistor, operating with an inductance functions as a series regulator. The base of the drive transistor (T52) is controlled by a saw-tooth waveform signal, derived by integrating (R3, (3) a square wave signal (Ur). When the output (Ua) attains a threshold valve the regulating stage is gated or inhibited by the saw-tooth waveform signal.
Patent DE-2907020-A1 (DE)
Inventor: WINKLER OTTO DR
IPC: C23C14/26
Filed: 1979-02-23
Abstract: The sample (3) which is to be vaporised is supported and simultaneously heated in a similar manner to that in the case of floating-melting of metals, the supporting force of the field being dimensioned, however, to be so low that the sample does not float but rests on a base (2). Since the change in position of the sample in the event of changes in field strength is then very low, the heating power supply can be adjusted independently of the requirement for floating and thus, for a given shape of the induction coil (1), can cover a greater range of resistance values, specific weights and vaporisation temperatures of the material which is to be vaporised. <IMAGE>

Patent DE-2926274-A1 (DE)
Title: Contact element for electrical connector of single piece pressing - in which identically dimensioned elements plug into each other
Inventor: KELL GERHARD R
IPC: H01R13/28
Filed: 1979-06-29
Abstract: The contact element can be used singly, to join two wires together, or used in an insulation housing to form a multipole connector. The element is a single piece metal pressing (1) with rolled over edges (2,3) which form the actual contact members. The element is asymmetrical along its longitudinal axis. The dia. of the smaller rolled over edge (3) is such that it fits into the bore of the rolled over edge with the larger dia. (2). As these rolled edges possess some elasticity a secure spring contact is made without the need to maintain very accurate dimensional tolerances. The insulation housings for connectors employing these contacts can similarly be designed so that only one moulding is required, and that, when brought together, two such mouldings mate. A simple connector system which is inexpensive to manufacture results.

Title: Metering and mixing liquids in fixed proportions - by magnetic floats rising with liquids in intermediate vessels
Inventor: BRANDNER EUGEN ING GRAD
IPC: G05D11/13
Filed: 1979-09-26
Abstract: Measured amts. of a number of liq. components fed by gravity from individual vessels with inlet and outlet valves into a collector are controlled by magnetic annular floats which move concentrically along the outside of a sealed tube inside the vessel. At intervals up the tube wall interior are reed contacts whose output signals as the float passes them control the various stages of admitting liq. and discharging it into the collector, with the level of each contact inside the measuring vessel determining tha amt. of that component present when a 'ready' signal is actuated preparatory to discharge. Each tube can have several reed contacts, permitting programming of different mixt. ratios. Suitable for large vol. or repeated mixing, esp. of dangerous liqs. eg. mixtures of hydrofluoric, hydrochloric and acetic acids for etching silicon semiconductor dice, and does not involve pressurising such liqs. as did known devices using controlled numbers of pumping strokes for each liq.
Patent DE-2940341-A1 (DE)
Title: Dosing small quantities of normally fluid substances - avoids fluid wastage by cooling drops to form solids for counting
Inventor: BAUMGARTNER ERICH RUDOLF DIPL
IPC: G01F13/00
Filed: 1979-10-04
Abstract: The method and arrangement for dosing normally fluid substances for the pharmaceutical, cosmetic, or food industries gives very accurate reproducible dosing of very small quantities without the losses associated with conventional arrangements because of their unusable fluid residual vol. Considerable savings can be made when expensive substances are being handled. The fluid is divided into drops and brought into a region where the temp. causes them to solidify. They are then manipulated into doses in the same region or in another whose temp. prevents them from melting. The dose regulation can be by counting drops or by weighing. The drops may be formed by spraying the fluid or by allowing it to form drops at an opening. The solidification temp. is achieved using a low temp. air or gas stream.

Title: Documents resistant to falsification - are coated with a transparent plastic film bonded with radiation curable adhesive
Inventor: NEUHAUS KARL-FRIEDRICH DR
IPC: B42D25/00
Filed: 1979-12-24
Abstract: Documents with increased resistance to falsification are made by covering one or both sides of an information carrier with films, at least one of which is transparent. The films carry a radiation-curable adhesive layer and are laminated to one or both sides of the document, after which the laminate is exposed to radiation which causes crosslinking of the adhesive. The adhesives are based on radiation-curable unsatd. monomers, oligomers and polymers and opt. a photoinitiator. Typical curable materials contain vinyl gps., (meth)acrylate gps., etc. and may be based e.g. on polyesters, polyethers, polyepoxides, polyurethanes, urethane-modified polyepoxides, urethane-modified polyesters and urethane modified polyesters. The coating film is e.g. of polyethylene which is opt. subjected to corona treatment before use. The information-carrying document is e.g. of paper and the lamination is carried out at up to 150 deg.C, esp. 70-120 deg.C. The irradiation is pref. carried out whilst the laminate is still hot. The process allows documents such as credit cards to be covered with plastic film coatings which are permanently bonded to the paper surface without damaging the paper, and without any possibility of removal without destroying the paper surface, thus giving excellent security against the document being altered.
