Abstract: 859,858. Sawing. STARTRITE ENGINEERING CO. Ltd. Nov. 12, 1959 [Dec. 2, 1958], No. 38828/58. Class 145. A combined thrust block and guide for varying widths of band saw blade comprises a housing 1 for two slides 3, 4, the slide 4 having blocks 10 each with a guide gap 11 and spaced on opposite sides of a thrust disc 8 rotatably carried by the slide 3, and the slides are simultaneously adjustable to move in opposite directions so that the correct proportion of the blade is accommodated in the guide gaps but the central longitudinal axis of the blade is aligned along the same path irrespective of the blade width. The slides are adjusted by oppositelyarranged cams or eccentrics 16, 17 on a shaft 15 which is slidably keyed to a sleeve 13 and has a knob 22 threaded to it at 21. The position of the knob on the threads is such that clockwise rotation from the position of Fig. 2 will tighten the knob on the shaft and sleeve and lock the slides before a pin 25 on the knob meets a pin 24 on the sleeve but unscrewing the knob half a turn in the opposite direction until the two pins abut causes rotation of the shaft and adjustment of the slides. A spring-loaded ball 26 seats in recesses in the sleeve flange 14 to provide a locating action and the knob may have an index mark co-operating with a scale on the sleeve.

Title: Dispersed plastic masses
IPC: C08L7/02
Filed: 1929-12-20
Abstract: Aqueous dispersions of rubber, gutta, balata, artificial rubber, &c. are rendered thixotropic, (i.e. are converted into a plastic or elastic gel which can be transformed into a liquid by agitation, stirring, or pressure, and reverts to the solid on coming to rest, or removal of pressure), by the addition of thixotropic colloids, or by the formation of thixotropic colloids therein.  Thus bentonite, or Dixie clay, may be added to latex, or dialysed bentonite (non-thixotropic) or China clay may be added and then rendered thixotropic by the addition of an electrolyte such as potassium chloride, sodium sulphate, caustic potash, or colloids naturally occurring in the latex may be rendered thixotropic e.g. by the addition of lithium sulphate.  By the addition of emulsions of substances immiscible with water, such as oils, elastic gels may be obtained.  In an example, 75 gm. of latex containing 75 per cent solids, are treated with 20 gm. of thixotropic Dixie clay, 20 gm. of colloidal zinc oxide, and 20 parts of a 50 per cent oil emulsion. The dispersions may be used for dipping, spraying, spreading, and casting; they will hold fillers in suspension without danger of settling.

Abstract: 1283590 Vigilance warning and testing device BIVIATOR SA 8 Aug 1969 [29 Aug 1968] 39698/69 Heading ASK A vigilance warning and testing device comprises a flickering luminous indicator 2, means to vary the flickering frequency of the indicator 2 controlled by a knob 3 and acoustical warning means automatically actuated when the flickering frequency falls to or below a set limit frequency. The indicator 2 may be energized from a multivibrator or oscillator. The means to vary the flickering frequency may be a potentiometer and the knob 3 actuates not only this means but also an indicating disc 5 divided into regions 7, 8 and 9 corresponding to different degrees of vigilance. The warning means, disposed behind the grid 10, is actuated electrically and may be a vibrating leaf spring or a resonator having a natural frequency equal to the limit frequency or a multiple of it. The flickering may alternatively be produced by placing a spring-motor rotated diaphragm between a light source and the luminous indicator. In either embodiment the flicker frequency may be arranged to decrease automatically, the apparatus being stopped by the user by pressing a stop button when flickering is first observed, the acoustical warning sounding if the stop button has not been pressed by the time the flicker frequency falls to the set limit.

In a continuous rolling mill simultaneously rolling a pair of fine wires 18; 19, Fig. 5, in twin passes of rolls 3a, 4a, Fig. 4, according to the parent Specification in which the speed of or one of the stands la, 2a is regulated by the size of loop 27 between the stands and in which the pass adjustment on one side of one stand is regulated by the size of the other loop 27<SP>1</SP>, compensation is provided whereby an adjustment of pass or roll speed according to the conditions of one loop 27 or 27<SP>1</SP> can be made without causing variations in the other loop. In one example the tilting of one of the rolls about one end due to adjustment at the other end varies the driving motor speed for the stand to compensate for the change in pass on one side. In another example the screwdowns 6a for the mill are differentially driven through separate gear boxes 31, 34 having different and opposite gear ratios so that the roll is effectively tilted about the pass B when regulated by the loop 27<SP>1</SP> without causing a change in the pass B and therefor without causing changes in the loop 27. In a further example a regulation of the motor driving speed by one loop effects a correction to the pass for the wire of the other loop so that the length of the loop is unaffected by the change in roll speed.
