Abstract: ABSTRACT OF THE DISCLOSURE     Improved method and means for identifying and quantizing an effectively periodic, steeply-rising wavefront of an input signal in the possible presence of low amplitude interference, as for example in systolic pressure determin-ing means utilizing a pressure cuff. A representation of the time-derivative of the steeply-rising wavefront is obtained.          The time-integral of the time-derivative is obtained over a certain interval in each repetition of the steep wave-front, as determined by the derivative exceeding a reference value.  A threshold level is established which is repre-sentative of the magnitude of substantially only the time-derivative corresponding with the steeply rising wavefront.          The time-derivative of the input signal is compared with the threshold level while the former exceeds the reference value to provide a control signal indicative of whether or not the time-derivative is representative of a valid steeply rising wavefront (as opposed to noise).  Finally, the integral of a particular time-derivative is recognized as the quantized value of the steeply-rising wavefront only if the control signal indicates validity.

Abstract: Abstract of the Disclosure A cassette well structure for viewing apparatus adapted to receive a cassette for processing and projecting a photographic film strip contained in the cassette. The cassette well is defined on one side by a wall surface formed in a chassis support member on which cassette cooperative viewer components are mounted, the wall surface extending between flange formations defining well floor and end walls against which an inclined plate is secured to provide and opened top well enclosure.  Cassette insertion causes the bottom wall thereof to upwardly engage biased members which operate to urge the cassette against a downwardly facing lip at the upper edge of the wall surface.  Laterally acting spring means supported on the plate member loads the cassette against the same surface.     Cassette ejection means moves the upper cassette portion free of the lip for ejection by the upwardly biased members. An aperture block assembly is supported on the cassette well floor and includes film engaging components retractable from an oper-ative position with cassette carried internal components by a shiftable blinder plate.

Abstract: Abstract of the Disclosure In a one-component type developer for electro-photography consisting essentially of a dry blend of fixing magneto-sensitive particles and flowability- and electric resistance-controlling fine particles, when an aromatic vinyl resin and/or an acrylic resin is used an a binder resin for the magneto-sensitive particles in combination with a low molecular weight olefin resin, the magneto-sensitive particles are much improved in the property of holding the flowability- and electric resistance-controlling fine particles on the surfaces thereof.  Accordingly, these fine particles cannot be substantially separated from the magneto-sensitive particles under agitation conditions, development condi-tions and fixing conditions.  As a result, contamination of the interior of a copying machine, especially an optical system, can be completely prevented, and also contamination of the background can be completely prevented. Further, the resulting fixed images have a very high resistance to friction and abrasion, and troubles such as blurring and flow of the image are not caused at all.

Title: Method of removing sulphur dioxide from gases, more particularly industrial waste gases
Inventor: HAESE EGON
IPC: B01D53/77
Filed: 1978-09-13
Granted: 1981-08-18
Abstract: ABSTRACT OF THE DISCLOSURE           The disclosure describes a process for the removal of sulfur dioxide from exhaust gases.  These gases are treated in a scrubber with a solution containing ammonium sulfite and ammonium bisulfite to absorb the sulfur dioxide.  A portion of this solution is drawn off and it is oxidized to form ammonium sulfate.  The gas is further treated with the oxidized solution while maintaining the dew point of the further treated gas beneath the temperature of the gas, whereby the escape of ammonia in the further treating process is prevented.  This process enables to prevent the loss of ammonia and avoid the use of expensive equipment for further scrubbing of the gas after treatment.

Abstract: ABSTRACT A rotating cutterhead projects forward from a tractor or other suitable vehicle and fells trees as the tractor is moved over land to be cleared.  The tree-felling cutterhead rotates in a direction such that its leading face moves upward and then rearward to kick the butt of a felled or falling tree upward and then move it rearward onto an apron.  The apron forms the floor of a flared throat leading to a chipping cutterhead.  An overhead live feed roll or a swinging feed rake positively feeds each tree rearward along the apron to the chipping cutterhead. Upright cutterheads may be carried at the sides of the flared throat to delimb a tree, or at least to crush the limbs inward, as the tree is moved rearward by the upper feed roll or rake.

Abstract: ABSTRACT:         "A device for determining the radiation absorption distri-bution in a three-dimensional examination zone"              The invention relates to a device for deter-mining the radiation absorption distribution in a three-dimensional examination zone which is irradiated from diff-erent positions which are situated in one plane and in which radiation sources are present. The radiation having passed the examination zone is detected by detectors which produce sets of output signals which are characteristic of the absorption of the radiation and wherefrom the absorption distribution can be reconstructed. The device comprises two detector arrays consisting of separate, adjacently arranged detectors, in a first plane and in a second plane which are situated at a distance from and parallel to each other. The device furthermore comprises radiation sources which are situated between the two extreme planes and which are ar-ranged to be rotatable around an axis of rotation which extends transversely of said planes. The radiation sources are line-shaped and are arranged parallel to the axis of rotation and diametrically with respect to the axis of rotation opposite a detector array.

Abstract: Abstract:            A method and a plant for recovery of oil floating on water. The plant comprises a closed container, either submersible or semi-submersible, floating in the sea with its upper edge at the boundary between oil and water. The mixture of oil and water floating on top of the container flows down through holes in the upper surface or collecting table of the container into the interior of the container. The mixture is then separated by settling and surplus water is discharged. A so called "calm bay" is formed above and in the immediate vicinity of the con-tainer by a collar reaching above the surface and attached to the container, in order to gather the oil to a thick layer, so that less water flows down into the container. After settling, the oil is pumped over to a tanker. The container can be equipped with heating coils in order to facilitate settling and enable pumping of the oil. A number of such containers can be combined to form a vessel.

Abstract: Abstract of the Disclosure The reductions gear of an electronic wristwatch having a stopping motor  and a sweep second, comprises three concentric output shafts adapted to be rotated at different speeds and oporatively connected with each other and with the shaft of a stopping motor through gear wheels. The shaft making one revolution per hour has mounted thereon a friction wheel and a bearing means including a bush press fitted in a bore of a plate of the wristwatch. The bush is mounted so that a portion thereof projects from the plate toward a bridge of the wrist-watch, coordinated with respect to the plate and attached thereto by threaded  means. The shaft making one revolution per hour passes freely through a bore in the bearing bush and is restricted from an unlimited axial displacement in one direction by an end face of the bearing bush, and in the other direction by an end face of that pinion which is mounted on this shaft with interference fit. This enables to arrange the entire toothed gearing between the shaft making one revolution per hour and the shaft making one revolution per minute to one side of the plate, facing the bridge, and to do without several complicated counterbores and milled areas in the plate, i.e. to simplify the manufacture of the plate and its structure.          The structure of the output shaft assembly enables to signifi-cantly reduce the overall height of the reduction gear.
