Inventor: GARDNER FREDERICK JAMES
IPC: G21C1/09
Filed: 1988-08-01
Granted: 1992-05-13
Abstract: A water cooled nuclear reactor comprises a reactor core, a primary water coolant circuit and a pressuriser arranged as an integral unit in a pressure vessel. The pressure vessel is divided into an upper chamber and a lower chamber by a casing, the reactor core and primary coolant circuit are arranged in the lower chamber and the pressuriser is arranged in the upper chamber. A movable diaphragm is positioned in the upper chamber, and is sealingly secured to the casing by a bellows arrangement to divide the upper chamber into a water filled space and a gas filled space. A plurality of surge ports interconnect the water space with the primary coolant circuit. The diaphragm moves to accommodate changes in the volume or pressure of the water in the primary coolant circuit and water space. The diaphragm is loaded by springs and dampers to prevent oscillation of the diaphragm. Alternatively the diaphragm may be an elastic membrane.

Title: Universal input data sampling circuit
Inventor: JIANG LEON LI-FENG
IPC: H04L7/00
Filed: 1997-11-18
Granted: 1999-03-31
Abstract: A circuit for detecting timing errors and for selecting the correct clock edge for mid-point data sampling, includes a rising edge sampling device for sampling an input data signal at a rising edge of an input clock and generating a first interim data signal. A falling edge sampling device samples the input data signal at a falling edge of the input clock and generates a second interim data signal. An error signal generation devise, arranged in each of the rising edge and falling edge sampling devices, generates an error signal if designated setup time and hold time requirements are not met. The error signal is one of an error-rise or error-fall signal. A state machine receives the first and second interim signals and the error signal. The state machine automatically outputs the first interim data signal to a logic device if the error-fall signal is detected, and outputs the second interim data signal to the logic device if the error-rise signal is detected.

Title: Steam manifolds used to reduce tube damage in rotary drier chambers - by relieving cyclic condensation when drying, e.g. plastics or flour particles
Inventor: ZANELLA G
IPC: F26B3/00
Filed: 1976-05-03
Granted: 1982-08-20
Abstract: A rotary drying chamber inclined for passing powdered materials countercurrent to a gas stream while being heated by contact with stream pipes passing longitudinally adjacent to the chamber walls is fitted with a rotary or stationary manifold interconnected with the upstream ends of the stem pipes passing through the chamber. Manifold is used for Luisville (RTM) type equipment for drying particulate materials such as powdered or peletted plastics or vegetables based flours. Interconnection of the steam pipes allows those in which condensation is occurring due to temporary contact with the damp feedstock to obtain steam from those pipes temporarily out of contact with the damp material at the same stage of the drier rotation and hence nut subject to a significant cooling load/condensation, at that moment. Arrangement avoids tube damage due to excessive condensation/steam hammer, esp. at the upstream ends of the pipe where the latent heat demands of the feedstock for removing volatile material is greatest. Tube life prior to replacement may be significantly extended.

Title: Copper complexes with bi:dentate ligands
Inventor: FIASCHI PAOLO
IPC: C07C/
Filed: 1982-11-09
Granted: 1988-02-24
Abstract: An audio signal processor treats a digitally encoded signal. Units (3, 12) sample the encoded signal and units (8, 13) calculate from the sampled values a correlation function relevant to a particular time frame. The function value serves to control an adaptive echo cancellation algorithm. The sampled signal portions are truncated (2, 5) so that only the arithmetic sign bit of each signal portion contributes to the function calculation. An incoming signal sample is initially treated in an extraction block arranged to determine the arithmetic sign relevant to that signal, the resulting sign bits being fed in sequence to a shift register arranged to store a predetermined number of sign bits. Outputs are provided from selected locations in the register in accordance with a control logic select circuit.

Title: Mechanical hooking and electrical connection device for linear tubular fluorescent lamp.
Inventor: VANIN MICHELE
IPC: F21V/
Filed: 1988-07-01
Granted: 1991-01-24
Abstract: This request for patent concerns a mechanical hooking and electrical connection device for a linear tubular fluorescent lamp.A necessary introduction, with the aim of clarifying the description, concerns the term, linear tubular fluorescent lamp, which has been abbreviated by the use of the word lamp. Every time the word lamp is mentioned in the description of the invention, it must be understood that this refers exclusively and only to a linear tubular fluorescent lamp.The device is made up of a support, which contains several electrical components for the power supply of the linear tubular fluorescent lamp, to which one or more arms are telescopically joined to the ends of the lamp projecting from said container. The arms are rotatable and eccentrically joined along a perpendicular plane with the lamp carrying mechanism, for the mechanical and electrical connection to the pin ends of said linear tubular fluorescent lamp.The device includes a mechanism, which operates on the pin ends of the lamp and allows for longitudinal movement of the lamp along its length, for the coupling to, or removal of its pin ends from the lamp carrying mechanism. It can be used in a variety of lighting equipment, since it has been designed with a connection that is adapted to the needs of the particular type of lighting equipment.This particular mechanism is intended for use in lighting equipment in which the longitudinal movement necessary for the substitution of the lamp, may become a determining factor due to limited space around the lighting fixture itself.

Title: Braking system for any sort of wheel locomotive system, said device being aimed at elastically accumulating part of the kinetic energy of the whole device itself during the braking phase, and at transmitting it back to obtain propulsion.
Inventor: VESCO GIUSEPPE
IPC: F03G/
Filed: 1989-04-27
Granted: 1992-05-15
Abstract: The present invention concerns a device applicable to any sort of wheel locomotive means (in particular bicycles), said device serving as a brake, an energy accumulator, and as a propulsion device. Said device is located on the wheel in a similar way to the traditional tumble brake and can either substitute or support the braking devices currently available. Said device can work as an energy accumulator or as a propulsion device thanks to the presence of one or more elastic elements, said elements being set inside the device's envelope, wherein said envelope is fixed to the wheel and indicated as "1" in Picture 1). Said elements are enwrapped either as a spiral, as a ribbon or a wire (indicated as "4" in Picture 1 and hereafter mentioned as "spring"); one of the ends of said elements terminates in one of their axis ("6" in picture 1), called "spring axis", while the other end terminates in an element ("5" in picture 1), said element containing said elastic elements (said element being called "spring envelope"). Container 1 of the device, spring axis 6 and spring container 5 rotate around the same axis, which coincides with the symmetrical axis of the wheel. By starting a braked control lever, said spring is loaded due to the action of elements making spring container 5 rotate and come into contact with the whole device, spring axis 6 being fixed to disk 12, said disk rotating around the same axis and not being able to move due to a blockage (assuming that the present device moves in normal motion direction). When said lever is released, the elements operating on said friction return to their resting position, thus releasing container 1 of the device, the bicycle wheel from spring envelope 5; spring 4 does not upload because its own axis 6 is invariably blocked and said free wheel device or cushion 7, which is set on wheel axis 2 and fixed inside container 5, is so oriented that it allows said container 5 to rotate only in the same direction of the wheel. By starting a second lever, the blockage of disk 12 is switched off and at the same time disk 8 frictions with container 1 of the device. As a consequence said spring, being provided with a free end, tends to unwrap, thus forcing disk 8 to rotate together with the wheel, obviously such that the means of locomotion goes onwards.
