Abstract: 191,107. Laidlaw, J. D. Sept. 3, 1921. Mills and apparatus. - In a machine for cutting, grinding, or breaking down large masses of pulverulent material such as artificial manure and of the kind comprising a rotary cutter movably supported from a portable framework so that the axis of the cutter may be moved relatively to the framework in order to traverse the cutter on the face of the material, the cutter is traversed in a rectilinear path along the framework. The cutter may be supported by a slide movable along rectilinear guides on the framework. The rotary cutter 3 projects laterally from a framework 4 which is mounted on wheels 5 an'd may be arranged vertically, horizontally, or otherwise. The cutter spindle 6 is mounted upon a slide 7 movable along guide-bars 8 by means of a winch 9 controlling a cable 10 which is attached to the slide and passes over a pulley 11. The slide is raised by means of the winch and falls by gravitation, the lever 13 of the clutch 12 of the winch being clamped to a rod 14 which slides, through guides and carries a tappet 15 adapted to be struck by the slide 7 to declutch the winch and allow the slide to fall. The slide may be positively traversed in both directions. The winch is driven through gearing 16 by a belt from a pulley 17 turning with a belt pulley 18 around which passes an endless belt 19 driven by a pulley 20 which receives motion through gearing 23 from an electric motor 24 on the framework 4. The belt 19 passes over a pulley 21 on the axle of the cutter 3 and around a jockey pulley 22 on the slide 7. As shown, the cutter spindle 6 is coupled to one end of a shaft 25 mounted on the slide 7 and carrying the pulley 21. A coupling-flange 27 may be provided at each end of the shaft 25. A conveyer or elevating device may be provided to receive the material loosened by the cutter and to deliver it to a convenient position for packing into sacks &c.

Title: Self-erecting camera with tubular lens mounting, with automatic distance-setting and coupling of the distance-setting arrangement with the range-finder
IPC: G03B3/00
Filed: 1955-08-16
Abstract: 776,964. Photographic cameras. DANZER, J. H. Aug. 16, 1955, No. 23549/55. Class 98(1) In a photographic camera, a lens and shutter assembly are carried 'at one end of a tube which is slidable through a focusing ring threaded into an opening in the front wall of the camera housing, cam segments on the inner face of the focussetting ring are engaged by cam followers on the inner end of the tube, and stop means limit the rotation of the focus-setting ring with respect to the housing. As shown, the lens and shutter assembly 8 is carried by a tube 1 slidable in a focusing ring 2, which is threaded at 4 in the camera housing 5. The ring 2 has cam surfaces 7 which are engaged by projections 10, 10a on the tube 1, the tube 1 being urged into engagement with the cams by torsion springs 20. Stops 11 limit the rotation of focusing ring 2. A further cam surface 12 on the ring 2 engages a follower 13 mounted on a lever 16, which carries the adjustable mirror 14 'of a short home base range finder. The projections 10a of the tube 1 engage channels 18 in the inner walls 19 of the camera housing to guide the lens mounting without rotation about its optical axis. An interior wall of the camera extends into the lens tube 1, and is formed at its front end 26 with an aperture which allows the passage of rays entering through the objective. The lens tube 1 may be pressed into the body of the camera against the action of springs 20 for compactness, and is retained by a locking pawl 24. In this position, the ends of the springs 20 extend into the field of view of the view-finder, and give a warning that the camera is not ready for exposure. To erect the camera, a button 23 is pressed, rocking a lever 22 which frees the lens tube 1 from the locking pawl 24.

Title: Physical treatment of solutions of organic acid esters of cellulose
IPC: C08B3/22
Filed: 1955-08-16
Abstract: Solutions of monocarboxylic acid esters of cellulose, especially such as have a high degree of substitution, e.g. cellulose acetates of acetyl value, as acetic acid, above 58 per cent and particularly above 60 per cent, are reduced in viscosity by subjecting them to a vigorous shearing action, whereby their suitability for spinning is improved.  The solvent may be trichloromethane, formic acid or m-cresol, but is preferably methylene chloride either alone or mixed with a minor proportion of an alcohol of 1-4 carbon atoms.  The process is particularly applicable to solutions of over 12 and especially over 15 per cent concentration, e.g. of about 100-300 poises viscosity at 25 DEG  C. The rate of shear should be at least 20 and preferably about 60 or more reciprocal seconds, and is defined as the value of V/D, where V is the linear speed in cm./sec. of the tips of the impeller blades or of the periphery of any other type of rotor effecting the shear, and D is the distance in centimetres from these tips at which the velocity of the body of the solution drops to zero.  The shearing treatment is preferably continued until the rate of decrease of viscosity of the solution is below about 5 per cent per half hour.  In general, the rate of shear multiplied by the time of treatment in seconds should be at least about 36,000.  The treatment may be carried out in an apparatus provided with a paddle-type impeller which can be operated at high speeds, and the paddles may be provided with a number of small openings. Alternatively the solution may be passed through a homogenizing mill or may be subjected to supersonic vibration.  In an example, a cellulose triacetate of acetyl value 62.5 per cent is tumbled for 8 hours with a 92/8 methylene chloride-methanol mixture to give a solution of 18.4 per cent concentration and 490 poises viscosity at 25 DEG  C.  The solution is then agitated for 15 minutes in a mechanical mixer provided with an impeller running at 1700 r.p.m. to give a shear rate of 65 reciprocal seconds.  The viscosity of the solution at 25 DEG  C. is thereby reduced to 400 poises and its filterability is substantially improved.

Abstract: 893,331. Laminates; coated fleeces. SCHICKEDANZ, G., [trading as VEREINIGTE PAPIERWERKE SCHICKEDANZ & CO.]. July 23, 1958 [Oct. 24, 1957], No. 23760/58. Class 140. A flexible compound fleece is produced by coating or impregnating a fleece of textile fibres with a solution or dispersion of an agent which is capable of binding or bonding the fibres together, and thereafter applying paper fibres in the form of a web or flakes, and heating and drying the compound fleece to consolidate it. Textile fibres are fibres such as wool, silk, cotton, staple fibre or synthetic fibres, that have an inherent elasticity and can be spun. Paper fibres are obtained by conventional methods of paper making from a cellulose pulp, and are short and inherently inelastic. Binding agents referred to are an acrylonitrile-butadiene copolymer dispersion and a polybutyl acrylate dispersion. The fleeces may be simultaneously or subsequently finished by the addition of dues and/or impregnants. Their surfaces may be modified by printing, embossing, roughening or calendering. Several fleeces, or two fleeces or webs of different kinds of fibre may be thus combined.

Abstract: 1307734 Digital read-out arrangements RICOH KK 20 May 1970 [21 May 1969 24 Nov 1969 24 Dec 1969] 24377/70 Heading G4H In an arrangement for reading out a clock or meter having a number of numeral wheels 1, contact pins 2 are provided on the wheels in a coded pattern and contact arms 4 are displaceable towards the wheel by means of a coil 7 to complete a circuit from terminal A, through contacts 2 and X, contact Y and arm 5 to terminal B. Each decade wheel has four tracks and four contact arms 4. When coil 7 is energized by a signal on terminals CD a circuit is completed between terminals A and B if a pin is present in that position. All the contact arms are carried on a pivoted plate 9 normally held in the raised position by springs 13. A push-button 11 may be provided having a cross-arm 12 and depending pins positioned over certain ones of arms 5. When the push-button is operated it is arranged to open a switch 15 in the line connected to terminal A so that the wheel is de-energized. Instead, the power from terminal A is applied to a combination of the arms 5 through the depending pins. This transmits a number identifying the clock or meter. In a modification, Fig. 7, the terminal A is connected through normally closed contacts Y with certain ones of the arms 5. Before coil 7 is energized, therefore, the identifying number is transmitted by terminals B and when coil 7 is energized, the reading is sent. In the form of Fig. 9 (not shown) there are two contact arms, for each track, one each side of the numeral wheel, and spring-loaded away from the wheel. The arms are connected by a cord and pulley or a linkage to move simultaneously towards and away from the wheel. When the coil is energized the two arms move towards the wheel and make contact with pins if they are present. There are only three tracks on each wheel, each value being indicated by six bits. In the form of Fig. 14 there are two pairs of movable arms, the contacts X1, X2 being between the arms. The arms are connected by cord 12 and pulley 11 to move together and close on the numeral wheel when the coil 7 is energized. Pins 2, if present, cause two Corresponding contacts to close. Coded numbers 27, 28 are moved into contact with the arms 21, 22 to close certain contacts X1, X2 and send the identifying number of the apparatus. The pins may be replaced by magnets and the switch arms by reed-switches which are operated when moved close to the wheel for read-out.
