Granted: 2003-11-25
Abstract: The present invention is directed to a method for extracting cholesterol from egg yolk. In accordance with the method, a mixture of egg yolk solids, water and oil is provided, The mixture is then subjected to moderate shear extraction conditions by repetitively pumping the mixture in a flowing stream through a conduit provided with at least one small diameter orifice and at least one screen mounted transversely to the direction of flow of the flowing stream. The mixture is then separated into water and oil phases by centrifugation to provide an oil please which retains the cholesterol and a water phase which contains the egg solids.

Title: Plural-mode stacked resonator filter
Inventor: FIEDZIUSZKO SLAWOMIR J
IPC: H01P1/205
Filed: 1993-10-28
Granted: 2002-12-31
Abstract: A filter for an electromagnetic signal is formed of a set of planar resonators, preferably of superconductor material, interspersed among a set of electrically conductive sheets, outermost ones of the sheets serving as ground planes, and the inner ones of the sheets having irises for coupling electromagnetic power between the resonators. The resonators and the sheets have a planar shape, are parallel to each other, and are stacked one upon the other. Dielectric material insulates and serves to support the resonators and the sheets in their respective locations. There are at least two resonators in the set of resonators, and at least one inner sheet of the set of sheets. A first coupling element serves to couple an electromagnetic signal to a resonator of the filter, and a second coupling element serves to extract an electromagnetic signal, preferably from another of the resonators. The first coupling element excites in a first of the resonators a first mode of electromagnetic vibration in a plane defined by the axis and a point of coupling of the first coupling element. Each of the resonators, in a preferred embodiment of the invention, is provided with a perturbation, such as a notch or a tab in a peripheral portion of the resonator, distant from the plane and from a coupling point for inducing a second mode of electromagnetic vibration perpendicular to the first mode, thereby to provide the function of a multiple pole filter with half the number of resonators,

Abstract: A hypodermic syringe has a syringe barrel with a distal end and a passage therethrough communicating with  a  fluid-receiving  chamber  in  the  syringe barrel.   A  barrier  extends  across  the  passage  to isolate the fluid in the chamber.  A needle cannula is mounted to a needle hub slidingly engaged at the distal end of the syringe barrel.  The needle cannula includes a proximally facing point for piercing the barrier in the passage to the chamber of the syringe barrel.  A needle shield is mounted to the distal end of the syringe barrel, and cam means are provided for cam-guided  rotational  movement  between  the  needle shield and the syringe barrel.  The cam shape causes the  needle  shield  and  the needle cannula to move proximally  for  initially  piercing  the  barrier  and then to move distally to  enable separation of the needle shield.

Abstract: A device for testing an amplifier.  A plurality of PN modulators are provided corresponding to a plurality of oscillators at stages preceding or following them, or fluctuation is given to division ratios at the oscillators.          Since each of n carriers combined by a combiner contains phase fluctuation, the possibility that the peaks will overlap each other or that the carriers having opposite phases will negate each other is very low.  The peak power in signals supplied to the amplifier to be tested is unlikely to vary, enabling accurate evaluation or testing.

Abstract: An air attrition mill is used to make an ultra-fine whole wheat flour having a granulation profile substantially as fine as conventional patent flour.  In particular, the granulation profile is characterized in at least 98 wt% of the whole wheat flour has a particle size of 150 microns or less.  This ultra-fine whole wheat flour is significantly different from conventional fine whole wheat flour.  Baked products made with this ultra-fine whole wheat flour have substantially improved textural characteristics. In terms of water absorption rate, gas retention properties, and other processing characteristics, ultra-fine whole wheat flours perform significantly better than conventionally milled fine whole wheat flours in many applications.  Examples are described in which this ultra-fine whole wheat flour is used in bread, cake, cookies, pastry, extruded snack foods, pancakes, pasta, biscuits, tortillas, extruded cereals and related product mixes.

Granted: 2000-01-18
Abstract: A housing is provided for a circuit breaker. The circuit breaker has contacts capable of being in an open state or a closed state, of movement between the open and closed states, and of generating a hot gas in consequence of that movement. An electronics module is provided for controlling movement of the contacts from the closed state to the open state. The housing has a first portion housing the contacts and a second portion housing the electronics module. The second portion is formed of a material subject to damage by the hot gas, and the first portion is constructed to protect the second portion from damage by the hot gas. The first portion is ideally formed of a thermosetting material resistant to damage by the hot gas and the second portion is ideally formed of a thermoplastic material, which reduces the cost of manufacturing the housing. A quick-mounting construction for assembling the second portion with the first portion further reduces the cost of assembly.

Abstract: A method of communication uses quantum crytogra-phy to encode and decode a signal. A key is distributed on a quantum channel, and information subsequently com-municated between the transmitter (1) and receiver (2) on a public channel to determine whether the key has been inter-cepted. A common transmission medium (3) is used for the quantum channel and public channel. A calibration signal is transmitted over the public channel on the common trans-mission medium to calibrate the system for the subsequent transmission of a key on the quantum channel. The transmis-sion medium may be an optical fibre and the transmitter may switch between a single-photon output and a multiple-photon output to provide the quantum channel and public channel respectively.

Abstract: An ear defender having one or more microphones (1) for detecting the sound level in the proximity of the wearer's ear, one or more speakers (4) for generating a noise reduction signal within the earshell, and a digital feedback controller (W) for generating a feedback signal derived from the output of the microphones and for applying said feedback signal to the speaker inputs, and estimation means (F') for providing an estimation of the earshell transfer function and subtracting from the input to the feedback controller a signal representing the estimated electroacoustic transfer function of the system. The operation of the digital feedback controller may be controllable by the output of a computational circuit (C) operable on the difference between the microphone output and the feedback controller input modified by a model (F") of the electroacoustic transfer function. A second, analogue or digital, feedback controller (W') may be included to provide an approximate feedback signal to the speakers and to improve the impulse response of the system.
