A method of preparing aromatics processing catalysts which comprises incorporating a noble metal with a member or members of a useful class of zeolites, with such incorporation occurring after zeolite crystallization, but prior to final catalyst particle formation, i.e. extrusion into particles. Said useful class of zeolites is characterized by a silica to alumina mole ratio of at least 12 and a Constraint Index in the approximate range of 1 to 12.

Pictures produced by a camera are corrected to eliminate the effect of camera shake or of unwanted movement of the camera relative to the subject being viewed. Using the apparatus of FIG. 1 the adjustments required for each frame of a cine film are established by displaying each frame on a screen 9 and using a light pen 10 to record the co-ordinates of two characteristic features, e.g. bright spots, on each frame. Circuitry 13, 14, 16, 17, 20, 21, 22, 23 calculates from these co-ordinates the co...

An information processor for rendering input data compatible with standard video recording and/or display equipment, comprising means for digitizing the input data over periods which are synchronous with the fields of a standard video signal, a store adapted to store the digitized data and release stored digitized data in correspondence with the line scan of a standard video monitor, the store having two halves which correspond to the interlaced fields of a standard video signal and being so arr...

This invention relates to food processing and in particular to a method and apparatus for processing food to form a foodstuff incorporating a filling encased in an edible sheet material. The method includes forming a sandwich of layers of edible flexible sheet material having a stabilized filling placed therebetween, placing the sandwich in an evacuating chamber, withdrawing gas in the chamber surrounding the sandwich and thereafter introducing gas into the chamber again to compress the layers o...

Crystalline semiconductor material is produced in strip or sheet form by a gas process. The corresponding amorphous semiconductor is vapour deposited on to a substrate material which is subsequently removed from the amorphous semiconductor. The semiconductor is then selectively heated to induce crystallization. Devices may be fabricated on the crystalline material in tandem with the deposition and crystallization processes.

Improved means for aligning processing members at various positions in processing passages of rotary processors. Essentially, the alignment means (or alignment elements) comprise a non-rotatable member positioned in the processing passage and shaped to at least partially interfere with flow of material in the passage. The shaped member is designed to perform certain processing functions on material in the passage such as blocking, collecting, mixing, spreading, restraining etc. The member is pos...

An apparatus for processing photosensitive strip material including a developing station, a fixing station, a washing station, and a stabilizing station. The developing station includes a plurality of developing applicator rollers disposed in three parallel horizontal banks, a drip feed conduit above the applicator rollers, endless conveyors between the banks, and idler rollers below the applicator rollers and conveyors. The fixing station is similar to the developing station but has only two pa...

A handwriting recognition device comprises a transducer surface responsive to a pen positioned thereon for representing the coordinate position of the pen as an electrical signal, and data processing means for recognizing a handwriting effected with the pen, the data processing means including a microprocessor based control controlling a read/write memory, a non-volatile read-only memory storing a handwriting recognition routine to store recognized handwriting in the read/write memory, and an in...

Apparatus for degrading safety fuel of the type containing an antimisting polymer and comprising a cylindrical vaned stator and vaned rotor in radially concentric array, whereby rotation of the rotor will cause safety fuel pumped through the apparatus to be subjected to sufficient shear and local acceleration to be degraded to a state acceptable to engines and their control apparatus.

Banana puree is heated with direct steam injection. A lower pressure zone is used to remove seeds and fiber while partially reducing the temperature of the puree. Thereafter, air and water vapor are removed from the puree prior to cooling in heat exchangers and the resulting product stored.
