Title: Access control system and method for smart cards
Inventor: TAKARAGI KAZUO
IPC: G06F21/00
Filed: 1987-10-26
Abstract: The invention concerns a system and method for controlling access to smart cards, to each of which several users have access. After the smart card has been delivered by a manufacturer, a system administration centre accesses it and enters an access procedure, access area and access authorisation for each further user into the smart card. The further users can have access to the smart card only by matching the access procedure, access area and access authorisation which have been set by the system administration centre. The smart card (100(a)) has a data input/output device (101(a)), a data processing device (102(a)) and a data storage device (103(a)). The access procedure, access area and access authorisation are set by the system administration centre, in collaboration with the data processing device (102(a)) on the smart card (100(a)). A control device which is provided as part of the data processing device (102(a)) of the smart card monitors the correctness of the access procedure, access area and access authorisation on the user side, and takes suitable security measures on unauthorised access. For example, these may consist of inverting an invalidity recording code or of blocking operation. <IMAGE>

Title: Method and circuit arrangement for the insulation testing of test pieces with large intrinsic capacitance and for the localisation of faults in power cables
Inventor: KRUEGER MICHAEL DIPL ING
IPC: G01R31/08
Filed: 1987-11-04
Abstract: A description is given of a method and circuit arrangement for the insulation testing of test pieces with large intrinsic capacitance and for the localisation of faults in power cables The method is characterised in that the high-voltage transformer is electronically driven on its primary side via a charging capacitor with a very low frequency voltage, which is overlaid with a higher frequency, and that on the secondary side of the high-voltage transformer, the component with the higher frequency is synchronously filtered out (demodulated), and that the high secondary voltage with low frequency is fed to the test piece, and that the measuring device is connected with the test piece via a switching device in the pulse-free period to the high-voltage transformer. The circuit arrangements for carrying out the method provide essentially for the primary-side driving of the high-voltage transformer in the form of pulse packets or in the form of a slowly changing voltage with superimposed square-wave pulses. Provided for demodulation on the secondary side of the high-voltage transformer is either a voltage-dependent resistor or spark gaps or a motor-driven, rotating synchronous switch.
Patent DE-3744023-A1 (DE)
Title: Method and apparatus for equalising the natural moisture of textile fabric webs before the application of a treatment agent
Inventor: LEHMANN JOACHIM
IPC: D06B15/12
Filed: 1987-12-24
Abstract: Fabric webs prepared for dyeing, preferably those consisting of natural fibres, absorb moisture from the atmosphere during storage. The moisture distribution often varies by 4 to 8% within a fabric-web package and becomes noticeable as unevenness during the application of the dyestuff, for example padding or minimum application. However, a fabric web must arrive for application with a moisture which is uniform over width and length. According to the invention, this object is now achieved in that the moisture is equalised by a brief steaming of the fabric web and by guiding it through a controllable IR field with a subsequent cooling zone. A subsequent moisture measurement serves, on the one hand, for controlling the IR field and, on the other hand, at the same time for determining the entry moisture directly upstream of the applicator unit.

Title: Throttle valve for a closed flow channel
Inventor: WALLER WOLFGANG
IPC: F16K27/02
Filed: 1988-02-27
Abstract: A throttle valve for a closed flow channel is to be recessed completely flush into the inner wall of the flow channel when open in order thereby to avoid flow resistance arising from the throttle valve. In order to be able to achieve complete flush recessing of the throttle valve not only in flat inner walls of flow channels but also in the case of curved inner walls of flow channels, the surface exposed to the flow in the open condition of the throttle valve is matched to the curvature of the inner wall of the channel. In the case of a cylindrical flow channel, the relevant surface of the throttle valve is thus likewise of cylindrical design. To ensure the minimum space requirement for the throttle valve in the wall of the flow channel, the throttle valve is composed of a completely recessable supporting beam and a shield attached to it and forming the curved surface.

Patent DE-3811370-A1 (DE)
Inventor: CAWTHORNE CHRIS E
IPC: E21B10/52
Filed: 1988-04-05
Abstract: A drill bit is assembled from a plurality of machined forgings that are welded together to form a unitary structure. Each forging comprises an upper body portion (12) and a lower leg portion (16). The lower leg portion is machined to form a shirttail section (24) and a journal section (18), which in turn is adapted to rotatively support a cone shaped cutter (20). In operation, the cutter (20) is oriented to describe a circular path, the outer diameter of which forms the gage diameter of the bit. The upper body portion (12) is machined to include a stabilizer lug (30) extending radially outward to substantially the same diameter as that formed by the cutters. The lower section of the lug (30) co-operates with a recessed portion of the leg to form a flow passage for enabling drilling fluid to more easily pass upwardly through the borehole annulus during operation. A plurality of polycrystalline diamond inserts are mounted within the surface of each stabilizer lug (30). <IMAGE>

Title: Process for the fluid extraction of fossil hydrocarbons from crude oil deposits, oil sands and tar sands, with subsidiary claims for the utilisation of geothermal and solar energy in conjunction with and by conversion via hot-air engines
Inventor: KILLESREITER HERMANN M M DIPL
IPC: E21B43/18
Filed: 1988-04-19
Abstract: The patent application contains, in the main claim, a process for improved crude oil recovery with the use of gases at or above their isopycnic densities and, in independent subsidiary claims and subclaims, processes for the hydrocarbon recovery from oil sands and tar sands by high-pressure extraction via fluid phases, assisted by a special treatment with ultrasonics or in a microwave heater, and a process for the utilisation of geothermal energy from new or not or no longer oil-producing boreholes, without rock fracture by countercurrent flushing at low flow rate. These processes result in technical embodiments which are described in independent subsidiary claims with subclaims and for which patent protection is claimed. These deal with an inversion-flushing head, with hot-air engines which are heated by hot water from geothermal and solar sources or by direct radiant heat absorption, and with combinations of these hot-air engines with current generators, cereal mills, water pumps and large fans. These inventions thus belong to the technical field of energy technology by recovery of fossil hydrocarbons as well as utilisation of terrestrial heat, and to the field of energy conversion into utilisable work output with suitable working machines such as hot-air engines.

Title: Fruit-tea sweets
IPC: A23G3/36
Filed: 1988-06-24
Abstract: A novelty from the confectionery sector, in this case fruit-tea sweets. The ingredients for the tea are in this case tea as desired     with sugar/sweetener and   (concentrated) fruit/fruit addition and/or   fruit vitamins.   If only vitamins are added, the fruit flavour must be produced artificially; it must possibly be reinforced even in the event of fruit addition. In accordance with the desired taste, greater or lesser amounts of the individual ingredients are selected to produce the base mass. With respect to tea, the caffeine (theine) content is balanced by removing or adding caffeine, depending on taste and requirement. Further additives which lead to a rounding off of the taste are possible, and in addition enhancement to achieve a particular component as a "highlight".

Title: Pressure-relief valve for closed circuits
Inventor: VOSS RICHARD
IPC: F16K17/04
Filed: 1988-09-03
Abstract: Pressure-relief valves advantageously protect the hydraulic face support and similar hydraulic units from rock bursts and similar overloads if they open briefly when the overload occurs in order to thus reduce the excess pressure. To this end, in the case of the valves equipped with a valve piston protected by an O-ring, the valve disc is provided with a base area shaped so as to increase the flow pressure, so that a specific high-lift action is obtained, which is further increased by subsequent clever conduction of the pressure medium in passages and a corresponding recess in the adjusting screw and a subsequent hose line of large volume. The socket connection required for the connection of the hose line is integrated in the valve head or the valve housing so that an adverse effect on the environment is impossible. <IMAGE>

Patent DE-3834220-A1 (DE)
Title: Method and apparatus for producing grooved plate-like shaped parts from wood
Inventor: GEORGUS RUDOLF DANIEL
IPC: B23Q35/10
Filed: 1988-10-07
Abstract: In the case of a method and apparatus for producing plate-like shaped parts from wooden boards, wherein the visible faces receive parallel milled grooves and the grooves are filled with a filling compound, the plate-like shaped parts being cut out from a larger wooden board using a template or the like, a groove course following traditional lines is achieved with simple means by producing the grooves before or after, or partly before and partly after, the shaped parts have been cut out and by using a freely guidable router with an end-milling cutter. In order to mill a reveal groove, the end-milling cutter is guided by means of a first parallel stop of the router parallel to at least one first outer edge of the cut-out shaped part or parts to be cut out. In this case, the first parallel stop lies either against the cut face of the first outer edge or against a stop rail arranged above the visible face of the shaped part. In order to mill internal grooves, the end-milling cutter is guided by means of a second parallel stop in each case parallel to the first outer edge of the shaped part, the parallel stop lying against the first outer edge or in a groove which has already been milled.
Patent DE-3835617-A1 (DE)
Title: Method for generating a frequency modulation
Inventor: DIRR JOSEF DIPL ING
IPC: H03M11/00
Filed: 1988-10-19
Abstract: In the previous circuits for generating a frequency modulation, a large number of side oscillations were produced above and below the carrier, the number being dependent on the modulation index. These side oscillations also determine the bandwidths. In the invention, the side oscillations are avoided in that the amplitudes of code pulses or of PAM pulses are converted into pulse duration pulses and after that are shaped into square width pulses, for example by means of an electronic relay. Using a low-pass filter, the square width pulses are then converted into a sinusoidal alternating current. The periods of the pulse duration pulses, of the square width pulses and of the halfwaves or periods of the sinusoidal alternating current are always the same so that the change in the PDM pulses also results in a change in the frequency of the coding AC, this therefore being a frequency modulation.
