A drying tunnel applicable to products of fruits and vegetables for drying, using ambient temperature dry air. The tunnel has an outer casing fitted with two independent stories which has openings at the ends of the upper floor, which crossed inside in an upward direction by a conveyor belt which is in turn crossed in a counterflow direction by a particular flow of drying air at ambient temperature. Humidity of the products is absorbed by traveling along the conveyor belt which passes through th...

Organic photoprecursors of amines are provided for use in photosensitive imaging systems, finding particular application in the preparation of lithographic printing plates. Said photoprecursors generate free amines on exposure to long wavelength UV or visible radiation, have high solubility in organic solvents, and include photolabile 2-nitrobenzyl functional groups. Methods for the synthesis of the photoprecursors are described, and the use of the said photoprecursors for the production of prin...

An optical reader capable of reading a bar code in a mounted state when an article carrying the bar code passes and of reading bar codes set in array on a menu sheet in a hand-held state has been disclosed. The optical reader comprises a light source, a scanner that is driven by a drive and scans light emanating from the light source, a plurality of reflection mirrors that reflect scanning light scanned by the scanner and create a scanning pattern composed of a plurality of scan trajectories, a ...

Polynucleotide sequences and other compositions useful for DNA polymorphism and other genetic analyses are disclosed herein. Also disclosed is a method for obtaining Variable Tandem Repeat polymorphism at a single genetic locus as well as other genetic analyses.

A drug preparation applicable to the oral mucosa is disclosed, comprising a soft adhesive film containing a systemic drug, the adhesive film comprising a homogeneous mixture comprising a vinyl acetate homopolymer, an acrylic acid polymer, and a cellulose derivative capable of being dissolved in or swollen with water and a lower alcohol. The drug preparation is less causative of an adverse feeling in the oral cavity on use, excellent in shape retention on water absorption, and adhesive to the ora...

A lens cap for a title for removably covering a photograph lens of a video camera which is capable of photographing an object at a very short distance to carry out title photographing is disclosed in which a part of the lens cap is provided with a region capable of removably attaching a title element such as a title recording paper thereto. Therefore, the title photographing in such as a macro mode with the above-described video camera can be achieved with the lens cap attached onto an exposed t...

A bicycle speed change mechanism in which five speeds are obtained with mechanism contained internally within the hub of a bicycle wheel. A pair of planetary gear mechanisms are mounted on a hub axle within a hub body, and two separate speed change rods are provided to selectively and separately control operation of the planetary gear mechanisms to obtain five numerically-different drive ratios. The separate speed change rods are manipulated at the control of the bicycle rider to select gear rat...

A knife cutter for the angular profiles includes a plate, generally triangular in shape, the posterior surface of which has a prismatic projection corresponding to one of the sides thereof. The side and the prismatic projection are arched in order to adjust in a complementary recess made for such purpose in the front surface of the knife bearing plate. The other two sides of the knife or the cutting edges thereof form a dihedral and are parallel to the cutting edges of a counter-knife.

A polysulfide sealing composition is described which contains, in addition to the hardening agents and optional fillers, softeners and other conventional additives, a mixture of a solid polysulfide rubber with terminal SH groups and a liquid polysulfide polymer with terminal SH groups, wherein the weight ratio of the respective solid and liquid polysulfide is 100:5 to 15. The composition may be used for the manufacture of insulating glass units.

A pulse width discriminating circuit and technique is disclosed which enables the rejection of pulses having a width less than and greater than predetermined limits. A received pulse is provided as one input to a counting circuit which is driven by a clock to provide count outputs as long as an input pulse is present. The counter has an output selected to indicate when the width of the pulse has exceeded a minimum time, and an output selected to indicate when the width of the pulse has exceeded ...
