Title: Improvements in or relating to polyvinyl butyral films
IPC: C08J7/00
Filed: 1962-06-21
Abstract: 944,686. Treating polyvinyl butyral films. DYNAMIT NOBEL A.G. June 21, 1962 [June 26, 1961], No. 23998/62. Heading B5B. The surface-tackiness of plasticizer-containing polyvinyl butyral film is reduced by immersing the film in a solution of polyvinyl butyral containing a precipitant for polyvinyl butyral, having a higher boiling point than the solvent, and in a concentration insufficient to cause precipitation of the polyvinyl butyral, and thereafter drying the film in a stream of warm air. The preferential evaporation of the solvent results in an increase in the concentration of precipitant in the applied solution, thereby causing precipitation of polyvinyl butyral on the film as a uniform, fine surface matting. The immersion bath is prepared by forming a solution of polyvinyl butyral with or without plasticizer, in, e.g., methanol and methyl acetate, in presence of a precipitant such as water, glycerine, an ether, an ethylene glycol, or an aliphatic hydrocarbon, e.g. benzine. Preferably, the concentration of precipitant is as close as possible to the precipitation point without actually precipitating the polyvinyl butyral. The film to be treated suitably contains 30% of plasticizer, e.g. triethylene glycol or diethylene butyral. In an example, a highly tacky plasticizer containing polyvinyl butyral film is briefly dipped into a mixture of methanol (100 parts), methyl acetate (100 parts), benzene B.P. 100-140‹ C. (150 parts) and plasticizer containing polyvinyl butyral (10 parts), and then dried in a stream of warm air.

Title: Control fo reversible vibratory equipment
IPC: B07B1/40
Filed: 1974-05-30
Abstract: 1465327 Controlling vibrations by tuning absorbers REXNORD Inc 30 May 1974 [2 July 1973] 24005/74 Heading F2X A resiliently mounted vibratory equipment, e.g. a vibratory conveyer, driven by rotating eccentric weights is provided with at least two sets of tunable dynamic vibration absorbers that may be selectively tuned to either oppose or aid the eccentric weights in producing vibration of the equipment along either of a pair of axes. A conveyer that may be vibrated to convey material in either direction so as to either discharge or level the material comprises a container or trough constituting a work member 1 resiliently supported for vibration on air springs 2. The work member 1 is vibrated by eccentric weights 3 mounted on a shaft 4 belt driven from a motor 5. The direction and amplitude of vibration of the work member 1 are controlled by four tunable dynamic vibration absorbers 6, 7, 8 and 9. Each absorber comprises a vibrating weight 10 guided by rocker arms 11, its motion being controlled by a pair of air springs 12, the spring rate of which is dependent on the inflation pressure. Absorbers 6, 9 form a pair adapted to vibrate along a path inclined upwardly toward the left while absorbers 7, 8 form a second pair adapted to vibrate along a path inclined upwardly toward the right. If one pair, such as 6, 9 are tuned so that the weights 10 in combination with the springs 12 are resonant at the operating speed of the eccentric weights 3, they vibrate at such amplitude and phase as to practically counterbalance the force of the eccentric weights 3 in the direction of vibration of the weights 10 and there is thus little or no vibration of the work member 1 in this direction. At the same time, the other pair 7, 8 may be tuned so that work member 1 and the weights 10 of these absorbers, together with the co-operating air springs 12, form a twomass vibratory system resonant near and preferably just below the operating speed. With this tuning the weights 10 of the absorbers 7, 8 vibrate in phase with the eccentric weights 3 to increase the vibration of the work member 1 along the path of vibration of these weights 10. By varying the tuning the amount of this reinforcement may be varied. It is possible to select both the direction and the amplitude of vibration by inflating the several air springs 12 to the proper pressures and control equipment for this purpose is illustrated in the lower portion of Fig. 1.

Title: An improved process for the separation of para-toluidine from mixtures of ortho-toluidine and para-toluidine
Filed: 1930-08-12
Abstract: By the treatment of mixtures of o- and p-toluidine with a limited quantity of sulphur dioxide, preferably in the presence of a little water, a solid compound of p-toluidine and sulphur dioxide, with or without water, is formed and is separated from the residual liquor by filtration and pressing.  The solid compound is decomposed by moderate heating preferably under reduced pressure giving practically pure p-toluidine.  The residue after the separation of the solid p-toluidine compound is similar in composition to the commercial o-toluidine but also contains a little sulphur dioxide and may be worked up by distillation preferably under reduced pressure or by washing with alkali to give pure o-toluidine the residue may be mixed with sulphuric acid and steam distilled or to give the hydrochloride the residue may be treated with hydrochloric acid; in both these processes the liberated sulphur dioxide should be collected.

Filed: 1972-05-23
Abstract: 1397952 Thread packages WINDINGS Inc 23 May 1972 24145/72 Heading B8M A hollow package of flexible material comprises layers of coils, each coil forming at least one figure 8, the cross-overs of successive coils in each layer progressing through an angle of less than 360 degrees about the package axis and being arranged to leave a radial opening in the package. The cross-overs in one layer are spaced differently from the cross-overs in the next layer. A layer of the package is wound by traversing the material on to a rotating spindle, the number of traverses being less in a given time than an exact multiple of one half the number of spindle rotations to cause the crossovers to progress. Before the cross-overs have progressed through 360 degrees, the winding is changed so that the number of traverses is greater than the exact multiple, this causing the cross-overs to progress in the opposite direction to form the next layer. The difference between the exact multiple and the number of traverses in the two layers is different, to produce the different spacing of the cross-overs in the two layers.

Title: A valve assembly for a fluid-operated ram
Inventor: WALKER JOHN GORDON
IPC: B30B15/16
Filed: 1967-05-24
Abstract: 1,221,654. Hydraulic presses. FORSYTH PRESSES Ltd. 8 April, 1968 [24 May, 1967], No. 24152/67. Heading B5F. [Also in Divisions F2 and G3] A pair of valves 20 are mechanically linked by a lever 11 in such a way that in an intermediate control position, fluid under pressure is admitted to both sides of a press ram 1 to stop it. The lever 11 is pivotally mounted at 12 and connected by a link 10 to a control handle 9. The handle 9 is adjustably fulcrummed on an arm 8 connected to a telescopic link 5 pivoted at 6 to the press frame and at 7 to a guide 2 on the ram 1. The lever 11 is weighted to bias the valves to a position in which the fluid is supplied to the underside of the ram. Each valve 20 is connected to a piston 23 in a cylinder 24 which is at the respective outlet pressure for exerting an equal and opposite pressure on the respective valve element, thus ensuring a pressure balance on each valve. Fluid under pressure is supplied to the system by a two-stage pump 4 having a plunger stage and a meshing gear stage. Operation.-When the operator depresses the handle 9, lever 11 is raised and both valves 20 adopt the intermediate position. Fluid is therefore supplied to both sides of the ram and returned to the reservoir (not shown). As the lever 11 rises further the RH valve 20 closes on its top seat 27 and the LH valve closes on its bottom seat 27<SP>1</SP> causing the fluid to flow through a LH by-pass 22 and port 28 to the upper side of the ram 1. Expelled fluid from the underside of the ram 1 enters the RH port 28 and leaves the RH outlet 17 through a one-way valve 29 to the upper side of ram 1. As the ram descends the tilt relationship of the lever 11 to the valves 20 is maintained until the operator halts the handle 9. This allows the ram to overtake the handle 9 whereupon the intermediate position is regained and the ram halts. A more positive stoppage of the ram may be ensured by providing a sub-circuit A.
