Title: Artificial dentures
IPC: A61C9/00
Filed: 1972-03-21
Abstract: 1376204 Dentures S SCHNEIDER and H S KATZ 21 March 1972 [22 March 1971] 13101/ 72 Heading A5R An artificial denture former is made by applying pressure in the mouth of the patient through a flexible spacer 44 to a layer of impression material 43 carried in an impression tray 20 to form an impression of the patients gum therein, the tray 20 being approximately contoured to the external configuration of a gum of the patient and containing a set of false teeth 42 in a trough therein, the spacer 44 being removed after taking the impression. The teeth 42 may be individual teeth or a plurality of teeth-sections or may be cast as a unit in the tray. Prior to the insertion of the impression material, the inner surfaces of the tray, except the bases of the teeth and tray surfaces therebetween, may be coated with adhesive. After removing the spacer, the impression material on the bases of the teeth is cut away. Alternatively, the teeth-bases may have a cover placed over them prior to insertion of the impression material, the cover and impression material thereover being removed after taking the impression. The former is then used to make a denture by placing denture-forming material in the former and taking an impression in the mouth for a long enough period for the denture material to set, the former comprising the tray 20 and impression material 43 then being removed to leave the teeth attached to the denture plate to form the denture. The impression material 43 may be alginate gel, and the tray 20 may be formed from an ethylene or propylene polymer or copolymer. The spacer 44, which determines the thickness of the denture-forming material in the final denture may be of thin flexible plastics material and may be of uniform thickness, or of varying thickness if a denture plate of non-uniform thickness is required. The denture-plate may be formed from a pigmented acrylic polymer, or an acrylic copolymer containing vinyls or styrene can be used, and may include a catalyst to promote rapid hardening. The denture plate may be of "rigid" material or "semi-hard" material or the denture may be formed with a plate having a "rigid" material outer surface and a "semihard" material inner surface by placing a shim, coated on one side with "rigid" material and on the other with "semi-hard" material, in the denture former prior to taking the plateforming impression as described and claimed in Specification 1346453. U.S.A. Specification 3460252 is referred to.

[Classes 65 (i) and 65 (ii).] A window or like stay bar is fixed at one end to a pivot pin forming a brake disc which is enclosed by a clamping member on the window or sill, a handle being provided to actuate the clamping member to hold the window in any position. The device is shown applied to a stay-bar d having a pin at one end sliding in a guide c on a window frame a while the other end is pivoted to an inwardly-opening window b. The latter end of the stay is fixed to a large pivot pin g bearing in a split socket e which can be tightened to grip the pin or disc g, and thus hold the window in any position, by a handle f having a face cam p bearing against a similar cam q fixed to the window, rotation of the handle causing it to move away from the window and draw on the inner part of the socket e by means of a bolt h ; a stop pin l prevents movement of the handle beyond the position in which the highest parts of the cams p, q are in contact. In modifications, the stay-bar d is made telescopic or is formed of two parts hinged together, the other end of the stay being pivoted to the window frame in each case. For windows opening outwardly, the friction pivot is preferably inverted and attached to the window frame, the other end of the stay being slidably or pivotally connected to the window, according to the construction of the stay.

Abstract: 778,724. Purifying water. IMPERIAL CHEMICAL INDUSTRIES, Ltd. May 2, 1955 [May 12, 1954], No. 13855/54. Class 46. In a water purification and supply system a gravity filter and an intermediate pure water tank are located on the same level to constitute a selfcompensating system in which water flows through the filter only when the level of the pure water is lowered below that of the water in the filter. The filter and tank may be incorporated in a plant mounted in a rigid framework provided with buoyancy tanks to permit it to float in the water to be purified. Such water flows through inlet pipes 2, disposed about a foot below its surface level, into first and second sedimentation tanks 1, 7 which feed it to the centre chamber of an annular gravity filter 13. Filtered water passes through a valve 19 to the intermediate tank 21. A motor driven pump 25 or 27 draws pure water from the tank to supply storage tanks 37, 39 where it is kept under pneumatic pressure, one tank 37 being provided with a pressure sensitive device 63 which switches the motor on and off to keep the pressure in the tank between desired limits. The motor also drives dosing devices 67, 69 for chlorine and alum. Air pressure in the storage tanks is " topped up " by a compresser 56 which also supplies pressure air for air lifts 5, 11, 17 used to clean the sedimentation tanks and gravity filter.
