Title: Coffee extract manufacture
IPC: A23F5/48
Filed: 1971-08-04
Abstract: Coffee extract manufacture Flushing gas used comprises a high condensing gas and a low condensing gas which form together a snow structure on which the aromatic vapours are condensed on leaving the grinding stage of the process. The easily condensable gas should be CO2, argon or water vapour, using nitrogen, helium etc as high condensing gas. Maximum 50% by volume easy condensing gas should be used, and two structures can be formed for the aromatic vapours to pass in sequence, with temperature drop from first to second say of minus 10 degrees C to minus 196 degrees C. The aromatic substances are converted subsequently by sublimating the snow structure and leading the gas with the aromatic substance through a powder extract. The grinder has a closed offtake for the gas mix leading to the condenser and inlets for the condensing gas mixture.

Abstract: `                                            Case 1559/DCS/db METHOD OF PRODUCING CHLORINE DIOXIDE FROM HYDROGEN CHLORIDE           ABSTRACT       This application relates to a process of producing chlorine dioxide which utilizes hydrochloric acid as a feed material.  The process may be operated to have substantially only chlorine dioxide and hydrogen as products.  The process utilizes an electrolytic cell to produce an alkali metal hydroxide, chlorine and hydrogen from an aqueous solution of alkali metal chlorides.  The alkali metal hydroxide and chlorine that are produced arc reacted to form an alkali metal hypochlorite, which in turn is converted into an alkali metal chlorate.  The chlorine is reacted with hydrochloric acid to produce chlorine dioxide, chlorine and an aqueous solution of alkali metal chloride.  The chlorine dioxide is recovered.  The chlorine produced may be used in the prior step by reaction with alkali metal hydroxide or may be burned with hydrogen to produce HCl and utilized in the process.  The aqueous solution of alkali metal chloride is recycled used as a feed material for the electrolytic cell.

Abstract: Abstract of the Disclosure A reversible self-propelled center pivot sprinkler system for sprinkling or irrigating a relatively large area surrounding a central pivot comprising an overhead water supply pipe extending outwardly from the center pivot point and supported by a plurality of spaced-apart, wheeled towers.  A drive apparatus is provided on each of the towers to propel the towers and water supply pipe around the central pivot point.  A control apparatus is provided on each of the towers for selectively operating the drive apparatus associated therewith to maintain the pipe and towers in an aligned condition as the water supply pipe is pivoted around the center pivot point.       The drive apparatus is connected to a trojan bar which is recipro-catably mounted on the tower and which is provided with a selectively movable double dog on at least one end thereof for engagement with drive lugs on at least one of the drive wheels of the tower.  The double dog is normally in position so that movement of the trojan bar in one direction will cause the dog to engage the wheel drive lugs so that the tower will be moved in a forwardly direction.  The double dog may be selectively moved to a second position so that the dog will engage the wheel drive lugs as the trojan bar is moving in a second direction to cause the tower to be moved rearwardly.  The double dog may be either manually moved or automatically controlled through the use of power cylinders.  A double ratchet-type brake is provided on the tower to prevent the tower from undesirable rolling in a direction opposite to the direction of driving travel.  The double ratchet-type brake may be operatively interconnected to the double dog whereby remote control or operation of the double dog also causes the double ratchet-type brake to be moved to permit the tower to roll in the desired direction while preventing undesirable rolling in the opposite direction.

Abstract: ABSTRACT OF THE DISCLOSURE           Apparatus and method for modulating quasi-mono-chromatic electromagnetic radiation utilizing a controllable diffraction grating.  A reflection diffraction grating is comprised of a material deformable in the presence of an applied electric field.  A first electrode, comprised of a flexible radiation-reflecting material, is applied to the first surface of the deformable material, forming a reflecting surface of the diffraction grating.  A second electrode is applied to a second surface of the deformable material.  The electrodes are arranged to provide a periodic surface dis-tortion on the reflecting electrode upon application of a voltage between the first and the second electrodes, thereby resulting in a blazed diffraction grating.  In addition, the blaze angle of the diffraction grating can be varied as a function of applied voltage, and consequently diffracted radiation pattern can be modulated as a function of the applied voltage.  The controllable diffraction grating can modulate the diffracted radiation in a digital ?? in an analog mode of operation.

Abstract: PASSIVE CHEVRON REPLICATOR                ABSTRACT OF THE DISCLOSURE         There is described a passive replicator device to be used in magnetic bubble domain systems.  The replicator is passive, i.e. does not require an active element such as a current source or the like, and both propagates and replicates bubble domains.  In a preferred embodiment, the replicator uses chevron type elements arranged in an appropriate pattern so as to interact with a pair of propagation paths wherein bubble domains are propagated.  A bubble in one propagation path is routinely transferred therealong and, concurrently, replicated by the instant device into another propagation path.  A plurality of elements arranged in juxtaposition to the chevrons assists in controlling the propagation of the bubbles through the respective propagation paths and, at the appropriate time, provides a cutting action wherein a bubble which is elongated between the chevrons of the two propagation paths is split into two separate bubbles.

Abstract: ABSTRACT OF THE DISCLOSURE           The present invention relates to an improved squelch circuit for use with an FM demodulator.  One of the most troublesomenoise problems in radio communications is the noise bursts which frequently appear at the beginning and/or end of a demodulated transmission due to the finite times required to detect the commencement or termination of a signal and to thereafter activate or deactivate the receiver output circuits.  These bursts are caused by short periods of noise signal.  The present invention provides improved squelch circuit for FM demodulators including a low pass filter for filtering out-of-band noise from the demodulator output signals, a delay line for time delaying the filtered signals, a gate for selectively passing the filtered demodulated output signals to an output terminal, and a control circuit for controlling the gate.  The control circuit includes a high pass filter for passing the out-of-band noise in the demodulated signals, a detector for detecting the noise level of the noise passed by the high pass filter, and a comparator for comparing the detected out-of-band noise level to a reference to develop a gate control signal which causes the gate to be opened when the out-of-band noise level is relatively low and to be closed when the out-of-band noise level is relatively high.
