Abstract: UNITED STATES PATENT                     APPLICATION OF          ROBERT A. STEFANIC, JAMES I. MALIN AND THOMAS A. STRAUB            FOR         A TRIM CLEANING APPARATUS AND METHOD     Abstract of the Disclosure A continuous automotive felt die cutting press, cuts patterns out of a web passing through it.   After exit of the web from the cutting press, the cut patterns and web are passed over a perforated roller that rotates about internally segmented zones having a plurality of removable solid and perforated sleeves.   The roller is capable of transmitting a vacuum or a pressure through any  one  of  its  internally  segmented  zones  with directional and force control being partially provided by the removable sleeve placement on the segmented roller.          Base guide means, which are adjustable, are located in the area between the perforated sleeves to provide a solid base for the cut patterns to rest upon during their vacuum separation from the web.  After vacuum separation of the cut pattern from the web the cut patterns are transported by conventional means  to a storage area, while the web, which remains secured to the perforated segmented  roller through its vacuum stage, is separated from the roller during the rollers pressure stage and transported by conventional means  to a  scrap storage area.

Abstract: ABSTRACT OF DISCLOSURE            A programmable automatic controller for operating a section of a glassware forming machine having a plurality of components which operate in a timed or sequential relationship with one another.          The controller includes a timing means for generating a digital signal in synchronism with the operation of the machine, wherein the digital signal provides an instantaneous indication of the time elapsed in each cycle of operation of the machine.  A random access memory (RAM) stores the status of every section component at each increment of time during each cycle of machine operation.  The digital signal addresses the RAM so that the statuses of all components for the corresponding time are directed to drivers which provide component enable or inhibit command signals.          Control means for adjusting the actuation and deactuation times of the section components provide information to a computer which updates an internal memory table organized similarly to the RAM.  The computer also controls the transfer of data from the internal table to the RAM in such a way that the data updating speed of the control computer is independent of the machine cycle speed.

Abstract: LASER BEAM SCANNING SYSTEM     Abstract In those high speed laser scanning systems, part-icularly those used in printing, employing an acousto-optical modulator driven at two or more carrier fre-quencies for scanning with a plurality of focussed beams simultaneously in order to reduce the required deflection scan rate and to better the rise and fall times of the waveforms, unwanted intermodulation effects arise.  These undesirable intermodulation effects can be reduced or largely eliminated by increasing the difference in the carrier frequencies such that the diffracted beam spacing is increased considerably and utilizing either a scan line interlace scheme or a staggered beam scheme to maintain the required scan line spacing.  In the latter case, the modulator is situated with the direction of propogation of the acousto-waves between zero and 90 degrees to the direction of image pattern scanning.  The angle is made sufficiently large as to make one light beam spot in one scanning line lag a corresponding spot in the adjacent line.  In a further approach the two tech-niques are combined.

ABSTRACT                     INFLATABE TUBE        The invention relates to inflatable tubes such as buoyancy tubes for inflatable lifeafts and is aimed to provide tubes with bends in them that can be formed with a considerable reduction in the number of cutting and joining operation conventionally required and with a corresponding reduction in numbers of seams and hence sources of leakage.          The invention provides a method of making such tube by overlapping and joining the longitudinal edges (231) of a suitable sheet material (230) to make a flattened tube (230A), marking on said tube a fold line (234) corresponding to the desired bend position, marking corresponding area (237A, 237B) one on each side of the fold line, folding about the fold line to bring and together these areas and then sealing the ends (232A, 232B) of the tube. By making a number of bends the ends of the tube can be sealed to each other, thereby making an endless tube of polygonal plan form.

Abstract: Abstract of the Disclosure The present invention relates to methods for prepar-ing a titanium tanning agent from sulphuric-acid titanium-ferriferous solutions and use thereof for leather tanning.      The method for preparing a titanium tanning agent from titanium-ferriferous sulphate solutions comprises introduc-tion, into said solution, of an oxidizing agent comprising a sulphuric-acid solution of a peroxy-titanium complex, fol-lows by the addition of ammonium sulphate and sulphuric acid to precipitate a double salt of titanyl and ammonium sulphate in the monohydrate form (NH4)2TiO(SO4)2.H2O. The precipita-tion of this salt is preferably effected prior to its forma-tion in an amount of 75-85% based on TiO2. The resulting salt is separated and washed; the filtrate and washings are com-bined and treated with ammonium sulphate to afterprecipitate the salt which is separated and recycled into the starting so-lution. The thus-prepared salt is used for tanning hides pre-treated with a tanning promotor: sodium salt of disulphodina-phthylmethane or phthalic anhydride, or aluminium alum, or a mixture of aluminium alum with urotropin; ammoniumtitanylsul-phate or phenol oligomers dispersed in lignosulphonic acids.      Tanning of delimed, or delimed and pickled, or delimed pickled and chromed bides is effected using the titanium tann-ing agent in the presence of lactic acid, aluminium alum or products of condensation of synthetic fatty acids with tri-ethanolamine.
