Patent GB-2034935-A (GB)
Title: Apparatus for and method of measuring the duration of events in computer controlled systems
IPC: H04M3/36
Filed: 1979-08-30
Abstract: A forwards binary counter (V) and backwards binary counter (R) are advanced from a common starting state in synchronism. A sum counter (T) is associated with a switching element the duration of use of which over an observation time period is to be measured. The sum counter has added to its count the backwards counter count at the beginning of a switching event and the forwards counter count at the end of the event. All the counters (V, R, T) have the same number of bit positions and so the sum carry is lost from the sum counter. The counter (VR) cycles are longer than the observation time period. The sum counter may include a counter component (C) for measuring the number of events whose duration is being summed. The current time in hours and minutes and the date can be recorded during the print out process. The application to the monitoring of switching elements in a telephone system is envisaged. Fig. 1 illustrates the logic states of the counters during a monitoring operation. <IMAGE>

Title: Stop control circuit for bushless dc motor
IPC: C07C47/546
Filed: 1981-05-29
Abstract: The circuit causes the motor to stop precisely by purely electrical action. A brushless DC motor M is provided with a bidirectional driving circuit (60), a servo circuit (70) for controlling the driving circuit, and a rotation detector (30) associated with the motor shaft to provide a phase signal that depends, in magnitude and polarity, on the particular rotational angle of the shaft, regardless of whether the motor is turning. The stop control circuit then includes an amplifier (81) whose output varies according to the phase signal, and a switch (90) that normally provides the servo signal to the driving circuit, but, upon command, switches over to provide thereto the output of the amplifier as a brake signal. Alternatively, the rotation detector can include two sensor elements separated by pi  DIVIDED 2, and the stop control circuit can include an inverting amplifier, a non-inverting amplifier coupled to one of the sensor elements, and a switch circuit with inputs coupled respectively to these amplifiers. A comparator provides a switch signal to the switch circuit in dependence on the phase signal from the other sensor element. In another embodiment, a differential amplifier provides a brake signal in dependence upon both the phase signals from the two sensor elements. <IMAGE>

Patent GB-2099738-A (GB)
Title: Rolling pipes
IPC: B21B9/00
Filed: 1982-05-28
Abstract: To avoid internal faults in the manufacture of pipes, in particular on piercing or pilgering lines, the atmosphere present in the interior of a pipe ingot, which would otherwise bring about oxidation of the internal surface of the pipe, is displaced. A mixture acting with a reducing effect is introduced, after inclined rolling and subsequent descaling, into the hot pipe interior, to displace the atmosphere present by deflagatory ignition of the mixture. This creates a non-oxidizing gas atmosphere within the pipe, which is maintained for the duration of the forming process.

Title: Self-adjusting game difficulty method and apparatus for electronic games
Inventor: RAINS LYLE V
IPC: A63F13/00
Filed: 1982-11-08
Abstract: Video game apparatus is provided with an electrically alterable read- only-memory (EAROM) for storing digital information that is indicative of, among other things, game-play difficulty averaged over a successive number of the games played. During the intervening time between each game played, information indicative of the skill of the player engaging in the immediately preceding game is merged with the average skill-level data. The average skill level data is compared to a predetermined skill parameter and, depending upon the outcome of that comparison, game play difficulty parameters are selected accordingly. The averaged difficulty information is then returned to the EAROM where it remains until later use or resetting. Stored in the EAROM, it remains involatile, despite loss of power to the overall system, whether inadvertent or intentional. The player can select by switches (20) the degree of difficulty relative to the current standard stored in the EAROM (42). <IMAGE>

Title: Isotope separation by standing waves
Inventor: ALTSHULER SAUL
IPC: B01D59/34
Filed: 1982-11-10
Abstract: The separation of isotopes is accomplished by scattering a beam of particles (11,12) from a standing electromagnetic wave (16). The particles may consist of either atoms or molecules, the beam having in either case a desired isotope and at least one other. The particle beam is directed so as to impinge on the standing electromagnetic wave (16), which may be a light wave. The particles, that is, the atomic or molecular quantum-mechanical waves, see basically a diffraction grating corresponding to the troughs and peaks of the electromagnetic wave (16). The frequency of the standing electromagnetic wave (16) substantially corresponds to an internal energy level- transition of the desired isotope. Accordingly, the desired isotope is spatially separated by being scattered or diffracted. <IMAGE>
