Title: Charge pump circuit
Inventor: TAKAGI KOTARO
IPC: H03L7/093
Filed: 1990-06-26
Abstract: A charge pump circuit for charging a capacitor in response to a phase difference between first and second input signals comprises a constant current source for providing a first constant current; a constant current sink for absorbing a second constant current; a circuit for substantially equalizing the magnitudes of the first and second constant currents; and a switching circuit for providing the first constant current and the second constant current flowing in opposed directions to the capacitor through an output terminal of the charge pump circuit in response to the phase difference between the first and second input signals to produce a voltage level across the capacitor corresponding to the phase difference. In a phase locked loop system employing such a charge pump circuit, a phase comparator produces a phase difference signal for controlling the provision of the first and second constant currents by the switching circuit to the capacitor. The capacitor acts as a loop filter supplying the voltage thereacross as a control voltage to a voltage controlled oscillator of the phase locked loop system.

Patent CA-2025112-A1 (CA)
Inventor: SHEA JOHN J
IPC: H01H71/40
Filed: 1990-09-12
Abstract: A circuit breaker has a magnetic trip assembly which can be adjusted to trip the breaker for low level overcurrents in the range of five to ten times rated current. The magnet trip includes for each pole of the breaker a helical torsion spring having one torsion arm which biases an armature against an adjusting bar to form a gap between the armature and a stationary magnetic structure in which magnetic flux strong enough to attract the armature and trip the breaker is induced by overcurrent. A second torsion arm of the spring has a first portion which bears against and slides along a pivot member carried by the adjusting bar to adjust the bias force applied to the armature by a given amount per unit travel of the adjusting bar over a low trip current portion of the range of travel of the adjusting bar. A second terminal portion of the second torsion arm of the spring extending at an angle from the first portion engages and slides along the pivot member on the adjusting bar to provide a greater change of bias force per unit travel of the adjusting bar at the higher trip current settings. Movement of the adjusting bar adjusts the spring bias for all poles of a multiphase circuit breaker simultaneously. The gaps between the armatures and the fixed magnetic structures of all the poles can also be adjusted by caroming surfaces on the adjusting bar against which the springs bias the armatures. In an alternative embodiment, the gaps can be adjusted separately for each pole by screws carried by the adjusting bar which bear against ramming surfaces formed by twisted tabs on the armatures.

Filed: 1990-10-17
Abstract: Abstract of the Disclosure A design which allows  for the  addition of a programmable delay between back-to-back I/O cycles in a computer  system  is  shown.   The  addition  of  the programmable delay allows utilization of the minimum amount of delay between back-to-back I/O cycles that is required to maintain compatibility between the computer system and the particular 8-bit or 16-bit I/O devices being used.  A programmed value reflecting a particular length of delay is used to generate a signal that is pulse position modulated with this length of delay.  The pulse position modulated signal is used in conjunction with a counter that counts out a predetermined length of delay dependent on the particular I/O cycle that has just been completed.  The pulse position modulated signal terminates the delay being provided by the  counter when the programmed length of delay has expired.

Abstract: PROCESS FOR REDUCTION OF CARBON DIOXIDE EMISSIONS AND RECYCLING OF WASTE PRODUCTS                            ABSTRACT            It  has been established through many scientific studies that one of  the  causes  of  warming of the  earth's  atmosphere  is  the presence  of carbon dioxide gas in the atmosphere.  In a  thermal power station,  the burning of fossil fuels leads to the emission of  gases of which the principal one is carbon dioxide.   By  the control and processing of these emissions, it will be possible to reduce  the quantity of carbon dioxide vented to the  atmosphere. Since  carbon  dioxide is fixed in organic form by the action  of photosynthesis under sunlight, the use of suitably cultivated, or genetically engineered or otherwise modified biological organisms under the right conditions of pressure,  temperature, solar flux, nutrients,  oxygen  and  other  necessary reactants  lead  to  an enhanced  rate  of  photosynthetic  fixing  of  carb,  and  the generation  of  biomass of considerable utility  in  the  further production of fuels, soil additives and other useful products.

Title: Suspended surfaces for the application of plasters
Inventor: MINAS IOSIFIDES
IPC: E04F21/00
Filed: 1990-10-19
Abstract: A B S T R A C T   Process and materials for the construction of suspended surfaces for plastering. The plasters are not attached or carried from the external surfaces of the walls in the usual way but instead are suspended in parallel to the main wall surfaces so that a constant width gap (air space) is formed between them. This process provides for the buildin ends of an appropriate system of overhang beams on the perimeter of the buildings external wall surfaces at the higher level of each storey. On this beam the appropriate panels of prefabricated reinforcement are hanged and fixed so that a final surface for the application of the plasters is configurated. The panels are capable of carrying the loads of the usual inorganic plasters and the relevant wind and mechanical loads associated with the buildings external wall. The advantages of using the suspended plasters are the fast, easy, cost effective and quality solutions for the construction of the buildings twin-leaf walls, having external insulation, with an aerated or not aerated gap.

Title: Matrix resonance memory electronic data recording and retrieval system
Inventor: HORSLEY PETER B
IPC: G11B20/00
Filed: 1991-04-22
Abstract: ABSTRACT       This invention relates to electronic computer memories and relates specifically to a memory using a matrix pattern for recording machine information. The method is based on the principle of matrix resonance, achieved by recording the same information in a number of locations regardless of overlapping other recorded information. Retrieval or read-out/playback of desired information is accomplished by selecting out the original matrix pattern and combining the selected identical signals to provide self-reinforcement of the combined signal and at the same time the unselected signals are attenuated by interference. The interference occurs in the following way. When binary signal elements are used, for example, a one is recorded as a positive value and a zero is recorded as an equal negative value. A filter analyser is adapted to measure the sum value of the combination of selected signal elements and then generates a one or a zero basedon the strength of the total combination. A total of random signal elements averages zero, whereas the average of a selected self-reinforced signal element is a zero or a one. Ordinary data storage methods are limited by the one-on-one ratio of bits of information compared to storage space. The method of matrix resonance permits the same storage space to be used many times. Selection of wanted information is achieved by keying-in a file name/number which generates the recording pattern and tracking pattern for the specific information that is to be released from the system.
