Patent GB-751802-A (GB)
Title: Impression taking materials and their production
IPC: A61K6/90
Filed: 1954-04-09
Abstract: In a process for manufacturing an impression taking material, particularly for taking dental impressions, by reacting a water-soluble alginate or pectate with a water soluble polyvalent metallic salt, the reaction is controlled by using the latter salt in the form of particles coated with a film forming substance which is insoluble in water but soluble in an organic solvent. The metallic salt preferably has a water solubility greater than 2 grams per litre at 20 DEG C., and may comprise potassium alum or calcium lactate or gluconate, and the film forming substance may comprise chlorinated or cyclized rubber or polyvinyl chloride. The gel forming reaction may be further controlled by the addition of sodium or potassium carbonate or pyrophosphate.  In the mixture may also be incorporated fillers such as heavy spar, talc, diatomaceous earth, precipitated calcium carbonate, alumina, magnesium carbonate, and calcined magnesia.  In one example 25 parts by weight of pulverized potassium alum dodecahydrate are suspended in 500 parts of a 10 per cent solution of cyclized rubber in methylene chloride and atomized and dried, 2.5 parts of the coated alum particles, 5 parts of sodium alginate, and 20 parts of precipitated calcium carbonate are stirred with 50 parts of water to yield a creamy mass which sets as an elastic gel.  In further examples coated calcium lactate particles are prepared by atomizing a suspension of the pulverized salt in a solution of cyclized rubber in petroleum ether or methylene chloride, or of chlorinated rubber in methylene chloride.  The coated calcium lactate particles may be mixed with sodium alginate, heavy spar, and talc, and a gel may be formed by adding a solution of the sodium salt of ethylene amine tetra-acetic acid.

Abstract: 1301984 Grinding LITTON INDUSTRIES Inc 21 April 1971 [2 July 1970] 10608/71 Heading B3D A double disc grinding machine comprises a pair of grinding disc supports 13L, 13R mounted for rotation and axial displacement motion one towards the other, respective rotary drives 15L, 15R for the supports, sensing means for separately sensing the occurrence of physical contact of respective ones of two grinding discs 14L, 14R, when carried by the supports, with a workpiece W positioned between the discs, and control means for controlling axial displacement of each of the supports as a function of the physical contact sensed by the sensing means. The supports 13L, 13R consist of spindles which are driven by belts from respective motors 15L, 15R and journalled in heads 11L, 11R slidably movable towards and away from one another by rotation of lead screws 17L, 17R engaging nuts 18L, 18R mounted in the heads. Rotation of the lead-screws is effected by pistons 39, 41 which are slidable in cylinders 36, 38 and move wormgears engaging worm-wheels 10L, 10R on the screws. The workpiece, in the form of a disc, is clamped between a headstock 23, which is advanced to a positive stop, and a tailstock 24, which is advanced with less force, and is rotated by a motor 26. After clamping of the workplace, the grinding discs are advanced axially at a rapid rate by fluid pressure supplied to the cylinders 36, 38. Exhaust fluid from the cylinders passes through lines 43, 46 to the rod ends of cylinders 42, 44, the pistons 48, 49 of which are connected to a yoke 47. After displacement of the yoke through a predetermined distance, a limit switch 4LS is actuated and causes the discs to be advanced at an intermediate rate determined by flow from the cylinders 42, 44 through valves 52, 57, 54 and a restrictor 58. When one of the discs contacts the workpiece, a load control relay associated with the drive of the contacted disc is actuated to stop advance of that disc by operating valve 52 and one or other of valves 59, 61 so that the other disc can continue to advance at the intermediate rate until it also contacts the workpiece whereupon a second load control relay is actuated to stop the feed of that disc. Both discs are then held against movement until a timer relay initiates a slow grinding feed, the rate of which is controlled by a restrictor 69 and the amount of which is determined by a displacement cylinder 64. At the end of the movement of the piston 66 in the cylinder 64, a switch 11LS is actuated to initiate a final sparkout grinding period.
