Abstract: 1415385 Dental restorative materials; polymerization initiator systems WALLACE A ERICKSON & CO 21 Feb 1973 [3 March 1972] 8594/73 Heading C3P A two-component system for use in preparing a dental restorative filling material comprises (a) a pastelike phase of a polymerizable mixture containing at least one polymerizable monomer (capable of being polymerized by an organic peroxide catalyst aromatic tertiary amine accelerator system), a finely divided filler material, and a said amine accelerator, and (b) a mixing sheet having at least on a surface thereof a said peroxide catalyst, the catalyst being available for incorporation into component (a) in sufficient quantity to catalyse polymerization of the polymerizable mixture when, in use of the system, component (a) is placed and spatulated on the surface of component (b). Component (b) alone constitutes a further embodiment of the invention. The preferred monomer is the 1 : 2 molar adduct of bisphenol A and glycidyl methacrylate, optionally diluted with ethylene glycol dimethacrylate. The filler may be fused or amorphous quartz, borosilicate or other glass. Benzoyl peroxide is the preferred catalyst and dimethyl paratoluidine the preferred activator. The mixing sheet may be a single sheet or a pad comprising a plurality of superposed sheets and may be formed from various paper materials, other cellulosic materials, or polyethylene or polyester film.

Filed: 1921-03-19
Abstract: 178,682. Astbury, J. March 19, 1921. Ploughs; lifting tool-frames manually. -An implement for simultaneously splitting two or more ridges comprises a frame mounted on two or more concealed rollers shaped to straddle and flatten the ridges without filling the adjacent furrows, a ridging-share being arranged behind each roller. The top frame comprises transverse members 1 and longitudinal members 2 and carries a draught pole and shafts 4 and steering- handles 5. The axle 10 of the hollow concave rollers 8 is mounted in depending angle members 6. The shares are carried by bifurcated beams 14 pivotally connected to a transverse bar 12 supported by brackets The beams 14 are adjusted vertically by bell-crank levers 15 and rack quadrants 16. They are pressed down by adjustable springs, and are guided in their movements by guides 25 on U.shaped bars 24 mounted on the axle 10. Each share is connected to its beam 14 by stems provided with three holes at the end to receive bolts. The middle bolt passes through the beam, and the outside bolts limit the pivotal movement of the stem about it. In a modification, the beams 14 are dispensed with and the shares fastened to the pivoted U-shaped bars 24, which are adjustably connected by chains to hooks on the upper framework. The splitting- apparatus may be fitted to a multiple-ridge turnip sower, the suspension chains being connected to hooks fixed to handles movable in two planes and adjustably secured by a stepped plate.

Strainer separators; driving.-A strainer separator particularly for treating sugar juice, comprises one or more funnel-shaped screens 9, 10, 11 carried by a shaft 5, to which the mixture is introduced and on to which it is deflected by a deflector 32. The solid material is held by the screen and a second deflector 33 which serves to divert the bulk of the juice through the screen. The solids pass away by the conical pieces 14 to the next screen or to the outlet 35, which is protected against entrance of separated liquid by the deflector 45. The liquid passes through the outlet 40. The separator shown in Fig. 1 comprises three screens 9, 10, 11 of increasing fineness, and these may be of perforated plate or any other form. They are supported on rings 12 carried by rods 13 and are connected to the shaft by means of the conical members 14, 14a, 14b, 33 and adjustable rods 50.
