Abstract: The circuit measures the level of an electrical signal, possibly with reference to a reference voltage. It can, with advantage, be applied to amplifiers with automatic gain control. 
<??>The circuit measures the level of an input electrical signal (Ve) and consists of an input amplifier (1), biased by a bias voltage, receiving this input signal (Ve) and producing an output signal (Vs), followed by a detector (2), itself followed by an integrator (3) delivering an integration signal (Vi). These three units form a measurement channel, the said integration signal (Vi) being the sum of a signal with a level proportional to the level of the said input signal (Ve) and an offset signal. The measuring circuit also incorporates a generator (6) producing a reference voltage (Vr), a compensation module (4) receiving the reference voltage (Vr) and producing a compensation signal (Vc), and a differential measuring amplifier (5) receiving the integration and compensation signals and producing a measurement signal (Vm). The bias voltage is the reference voltage (Vr). The compensation module (4) comprises stages corresponding to the units in the measurement channel in order to pass on the reference voltage (Vr) in conditions similar in all respects to those of the measurement channel. This produces a correction signal having the same value as the offset signal, the correction signal being included in the compensation signal (Vc).

Abstract: A blade sharpener of the kind having a pair of overlapping plates (8) which are relatively arranged to form a vee shaped sharpening recess (10) between them. Each of the opposite sloping sides of that recess (10) is formed by an operative edge (9) of a respective one of the two plates (8), and each of those edges (9) extends between a front face (12) and a back face (14) of the respective plate (8). A relatively sharp corner (13) is formed between each operative edge (9) and the back face (14) of the respective plate (8), and a relatively blunt, e.g. rounded, corner (11) is formed between each operative edge (9) and the front face (12) of the respective plate (8). The plates (8) may be mounted on a member (6) which can pivot between a position at which the plates (8) tilt forward and a position at which the plates (8) tilt back. Spring means (27,28) may be operative to engage the back edge of a blade located in the recess (10) so as to press the cutting edge of the blade against the plates (8). The arrangement is such that longitudinal movement of a blade through the recess (10) in a direction towards the plate front faces (12), causes the sharp edges (13) of the plates (8) to be operative to sharpen the cutting edge of the blade, whereas in the reverse direction of the blade the blunt edges (11) come into contact with the blade cutting edge so that sharpening of that edge does not occur. <IMAGE>

Abstract: In a method for decomposition of hydrocarbons for the production of hydrogen and carbon black, the feed stock is passed through a plasma torch, which causes a pyrolytic decomposition of the feed stock. The feed stock is transported through the plasma torch (A) in a cooled lead-in tube (1) and undergoes a first heating in an area in the immediate vicinity of the plasma flame. The material thereby produced is passed on to one or more subsequent stages where the final and complete decomposition of the hydrocarbons to carbon black and hydrogen occurs. In this area further raw material may be added which causes quenching and reacts with the already produced carbon black. An increase is thereby caused in particle size, density and amount produced without further energy supply, whereafter the products produced are expelled and separated and hot gas may be transported in a return pipe to the torch, in order to further increase the energy yield.

Abstract: A multiprocessor computer system includes fault tolerant power up logic for finding a functioning CPU to operate as logical CPU0. Each microprocessor has a physical location designation which remains constant. When the system is powered up, all of the CPUs except the CPU in physical slot 0 (CPU P0) are initially placed in an inactive sleep state. The microprocessor in physical location 0 performs its power on self test (POST), and if the CPU functions properly, the CPU is designated as logical CPU0 (CPU L0). The microprocessor then awakens the remaining CPUs and boots up the rest of the computer system. If CPU P0 is not functioning properly, after a given time period the system awakens the processor in the next physical location and repeats the process of testing the CPU. The process repeats until an operating microprocessor is found to perform the CPU L0 functions.

Abstract: A secure computer controlling access to data storage devices via a card reader. A microprocessor-controlled card reader interface logically connected to the card reader and the central processing unit (CPU) of the computer reads and writes information from and to a card placed in the card reader and performs additional functions in response to commands received from the CPU. The card reader interface includes an encryption engine for encrypting data in a data storage device and a boot ROM containing verification program code executed during an initialization procedure. The verification program verifies that a valid user card has been placed in the card reader, reads one or more questions from the user card, asks the questions of the user and verifies the answers against the contents of the card. If authorization is verified, the card reader interface permits the user to access the encrypted data. Otherwise the user is denied access to the data by one or more of the following methods: freezing the system bus, and requiring the user to reset the computer and re-enter the verification program; logically destroying the data in the data storage devices; and physically destroying the data storage devices.
