Abstract: Abstract of the Disclosure Apparatus for the dynamic in-circuit testing of digital electronic devices employs a hardware testing circuit that is set by a microcomputer which takes no direct part in the test, so that the test hardware speed is not limited by the computer speed.  The apparatus comprises a library of devices corres-ponding to the devices to be tested, the library including a ROM containing the information regarding the devices needed by the microcomputer for its purpose.  An internal interface or router receives signals from the test device that are input signals to its terminals and routes them directly to the corres-ponding selected device in the library where it becomes an input to that device also.  Signals from the test device that are output signals are routed instead to a comparison block where they are compared with the respective output signals from the library reference device.  The signals at each corresponding pin of the two devices are compared and upon the presence of a fault the apparatus stops and identifies the pin or pins on which a fault has been detected.  An external interface is provided to shift the signal levels as required between the test device and the TTL logic devices of the apparatus.  The signals are sampled during timed periods to account for different propagation times through the apparatus, and different operating speeds of the devices.  Provision is made for external or internal clocks, reset and ground connections.

Abstract: ABSTRACT OF THE DISCLOSURE     The invention relates to a fibrous structure having a roughened surface and to a process for producing the same.          The fibrous structure has surface irregularities whose structure is such that the distance between the adjacent projections is 0.01 to 0.7 micrometer and the area of the concave parts accounts for 0.1 to 0.8 square micrometer per square micrometer of the irregularities.  The fibrous structure is produced by attaching fine particles to the fiber surface in an amount of 0.001 to 10 wt% based on the weight of the fiber, the fine particles having an average primary particle diameter smaller than 0.5 micrometer and being more inert than the fiber-constituting polymer base material in low-temperature plasma, and treating the fiber with low-temperature plasma, thereby forming projections which are larger than the average primary particle dia-meter.  Upon dyeing, the fibrous stucture has a very good color depth.  In addition, it gives a creak feeling better than silk does, and it has new uses.

Abstract: A MEMBRANE PROCESS FOR CONVERTING SODIUM SULFATE INTO SULFURIC ACID         AND SODIUM CARBONATE     ABSTRACT OF THE DISCLOSURE     A system for converting sodium sulfate ore into chem-icals of which H2SO4 and Na2CO3 are examples, utilizing a membrane process, the basic electrodialysis cell of which is located, usually  as a series of such cells, between cathode and anode comportments.  Each cell constitutes a pair of cation permselective membranes between which a bi-polar membrane is disposed in spaced relationship thereto with the cation permselective face thereof confronting the cation permselective membrane and the anion permselective face thereof facing the other cation permselective membrane.  The cation permselective membranes of adjacent cells are common to such adjacent cells.  All of the cation permselec-tive faces of the bi-polar membranes face the cathode electrode and all of the anion permselective faces of the bi-polar membranes face the anode electrode.  Each cell includes a base zone and an acid zone.  Each acid zone is defined by a cation permselective membrane and the confronting cation permselective face of the bi-polar membrane and each base zone is defined by a cation permselective membrane and the confronting anion perm-selective face of the same bi-polar membrane.  The acid zone is fed by a water solution of a sodium salt, for example Na2SO4 and Na2S and the base zone is fed by a saturated water solution of NaHCO3 or by a water solution of a mixture of NaHCO3 and Na2CO3 or by a mixture of a water solution of Na2CO3 and CO2 which reacts with the Na2CO3 to form NaHCO3.  The feeding of these composite solutions to the different zones results in increased current efficiencies by removing free H+ ions from the acid zone and free OH- ions from the base zone.  Thecathode and anode electrodes are disposed in respective compartments through which water solu-tions of NaOH circulate.  The cell is part of a plant in which other treatments are performed.

Abstract: ABSTRACT OF THE DISCLOSURE         A constant-speed regulator keeps the speed of a motor vehicle at a desired level.  The constant-speed regulator has a selector device via which a user selects the desired constant speed d a programmable central unit having a memory unit into which data concerning the driving situation is fed, such data including the use of the clutch and the brake, as well as the momentary speed.  Regulating devices controlled by the central unit regulate the power and the rotary speed of the engine of the vehicle and, consequently, the speed of the vehicle.  A permanent memory in the memory unit of the constant-speed regulator stores the data despite possible interruption in the supply of ignition current.  The memory unit includes several memory positions for different constant speeds, which set values of constant speeds, individually or together with a pulse concerning the driving gear.  The driving gear pulse may be stored by the selector device in the memory unit and read out of the memory unit to form set values for the regulato Thus, there may be a connection from the gearbox of the vehicle to the memory unit, whereby when a set value for constant speed is stored in the memory unit, information of the gear engaged at that time is also stored in such memory unit.  Furthermore, the constant speed regulator may be provided with a warning device connected to the connection between the memory unit and the gearbox, to warn of an excessively low or excessively high speed of rotation of the engine and thereby indicate the possible necessity for changing the gear.
