Title: Individual dental implant and a method for its application to a patient
IPC: A61C8/00
Filed: 1978-03-01
Abstract: Current endo-osseous implants used in mouth surgery require a large cut to be made in the jawbone which heals in approximately 15 days and may give rise to complications. The implant in question eliminates this drawback and allows the wound to heal in only 5-6 days. It comprises one or two thin parallel plates (1) which are inserted into corresponding narrow semicircular cuts made in the jawbone, these plates having lower apertures (4, 6) and upper apertures (7, 8) which enable the implant to be anchored in the jawbone as the latter heals. The plate 1 (or the plates) is surmounted (are surmounted) by the stop plate (17) which is also provided with apertures (16) which terminate at the top in the pin holder (18, 19) which holds the pin onto which an artificial tooth or bridge is fixed. <IMAGE>

Title: Improvements in and relating to operating mechanism for valves
IPC: F16K31/122
Filed: 1930-03-14
Abstract: 342,581. Fluid-actuated valves; accessories. SEMET-SOLVAY ENGINEERING CORPORATION, 61, Broadway, New York, U.S.A.-(Assignees of Tymstra, S. R. ; 61, Broadway, New York, U.S.A.) March 14, 1930, No. 8347. Convention date, March 23, 1929. [Class 135.] In order to supply varying amounts of oxygencontaining gas in the blasting cycle of a gas generator such as a water-gas set, a valve is provided in which a rapid partial opening, a continued uniform slow opening to a predetermined extent, and finally a rapid closure, in sequence are obtained. A sluice valve 4, controlling the flow of gas in a pipe 2, 3 is connected through a spindle 6 with a double-acting piston 7 movable in a cylinder 5, and pipes 13, 10 supply and exhaust fluid pressure above and below the piston 7 respectively. The pipe 13 comprises three branches 29, 35, 33 in parallel. The branch 29 is controlled by a regulatable needle valve 31, branch 35 by a check valve 36 permitting only the flow of fluid into the cylinder above the piston 7, and branch 33 by a lift valve 34. The lift valve 34 is operated by a balance weighted lever pivoted at 42, one arm 40 of which carries a, weight 43 and the other arm 41 of which carries a detachable jockey weight 44 loosely slidable on a screwed rod 23 which is rigidly attached at 24, 22 to an extension 15 of the piston rod. An adjustable nut 26 on the rod 23 serves to raise the weight 44 off the lever 41 for the purpose of closing the valve 34. A screw-threaded tube 17 slotted at 20 and fixed at 18 to an extension 19 of the cylinder 5 guides the piston rod 15 and carries an adjustable screwed hand-wheel 47 which limits the total opening of the valve. In operation, fluid pressure is admitted to the cylinder 5, in the position shown, through the pipe 10 and the piston 7 rises rapidly, fluid being exhausted from above the piston through the valve 34 and the adjustable slow leak valve 31. At a predetermined opening of the main valve the nut 26 raises the weight 44 thus closing the valve 34. Fluid then exhausts through the leak-off valve 31 and slow opening of the main valve takes place until the piston rod 15, 22 contacts with the stop 47. After a predetermined time fluid pressure may be admitted through a valve (not shown), the pipe 13<1> and check valve 36 to the cylinder above the piston 7 to close the main valve rapidly. Rapid and gradual closing in sequence may be obtained by providing the pipe 10 with an arrangement similar to that associated with the pipe 13.

Farbenindustrie Akt. - Ges. ; Frankfort - on - Main, Germany) Jan. 30, 1936, No. 8371/35. [Class 14 (i)] A device for dispersing gases in liquids by forming a mixture of the gas with part of the liquid and then forcing the mixture through narrow slits into the body of the liquid, comprises supply pipes 1, 2 for the gas and liquid, a baffle plate 3 in front of the pipe 1, and a plate 4 which forms, with the end of the pipe 2, the narrow slit. When the device is immersed in the liquid in a container and gas is forced up the pipe 1, it spreads out as a fine layer and is dispersed in the liquid supplied to the pipe 2 from the container by a pump. The resulting coarse dispersion is refined by passage through the slit between the pipe 2 and plate 4. The slit has a width of from 0À3 to 2 millimetres. In a modification, the dispersion passes between concentric pipes before reaching the plate 4. In another modification, a common baffle plate fulfils the functions of the plates 3, 4. Specification 11643/04, [Class 14], is referred to.

Title: Improvements in and relating to slide-rule calculating devices
IPC: G06G1/14
Filed: 1955-03-23
Abstract: 829,868. Calculating apparatus. STACEY, J. A. W. March 29, 1956 [March 23, 1955], No. 8452/55. Class 106 (1). Calculating - apparatus cornprises a member bearing a logarithmic rectangular co-ordinate network of lines and a relativelymovable member bearing a curve corresponding to the equation x<SP>-1</SP>+y<SP>-1</SP>=constant, when x and y are plotted on logarithmic scales, and is used to solve an equation in which the reciprocal of one variable is equal to the sum of the reciprocals of the two other variables. Thus, it is of use in connection with resistances in parallel, condensers in series, or to determine the focal length of a lens given associated object and image distances. The base of the apparatus, Fig. 3, bears the coordinate network which is arranged at 45 degrees. This corresponds to a portion of a complete network, as shown in Fig. 2, and is graduated along two sides. A transparent slide on the base bears a portion of a curve which corresponds to a part of any one of the family of parallel curves corresponding to the abovementioned equation with different constants. Thus, by appropriately positioning the slide, any one of that family of curves may be represented. The value corresponding to the particular curve is shown to equal half the value represented by the intersection of the curve with the edge of the network (i.e. the diagonal in Fig. 2) and consequently the slide bears an index mark spaced by a distance corresponding logarithmically to the value 2 to the scale of the graduations along the edge. Thus, e.g., if the values of two parallel resistances are known, the slide is moved to position its curve over the intersection of the corresponding co-ordinate lines and the resistance of the combination is indicated against the index mark. The slide also carries two further curves and two additional index marks corresponding to tolerances of Œ10%, or alternatively a scale extending from +20% to - 20%. Parallel straight lines may also be marked to correspond to given ratios between the quantities represented by the co-ordinates.

Abstract: 152,049. Knolles, E. Miles-, and Butcher, C. A. April 4, 1919. Valves.-The compression pressure in an engine cylinder is kept constant although the weight of charge may vary by a loaded loose piston 3. The preferred method of loading is by placing the space 2 into communication with a relatively large chamber 8 containing air under the required compression pressure. The piston is arrested by a stop 4 in one direction, and by trapping air in the end of the space 2 when the explosion forces the piston beyond the ports 7. The piston may be formed on the end of a rotary sleeve valve which surrounds the piston.

The joints between the surfaces form gutters A<4> along which the solids pass under centrifugal force. Discharge apertures B<2> are made in the shell at the tops of the gutters, and these may be closed bv rods B<4> associated with bell-crank levers and the sleeve E<2> on the extension C<4> of the driving spindle. The upper end of the shell forms an inturned lip B<1> over which the liquid is discharged. The unclarified liquid, such as cane juice, is introduced through the hollow shaft C<2> and guided to the bottom of the shell by the casing C<3>. Any solid matter travels along the gutters A<4> to the discharge apertures B<2> and thence to the gutter D<3>. In a modification the separator is of the suspended type; the planes bounding the blocks A<2> are inclined to the axis of the basket and the unclarified liquid is introduced into the shell through holes in the bottom plate. The surfaces in the shell may be of one inclination only, or alternate surfaces may be of opposite inclinations. The rods B<4> are moved bv centrifugal force to close the apertures B<2>, and they are moved to open the apertures by an upward movement of the sleeve E<2>, Fig. 1.
