Title: Improvements in the manufacture of artificial teeth
IPC: A61C13/00
Filed: 1939-07-24
Abstract: The adherence of porcelain artificial teeth, crowns, inlays &c to the support on which they are to be secured by sealing is increased by coating the sealing surface with alumina grains held by a binding agent, and firing to vitrification.  A suitable binding agent is porcelain milk, which may be applied to the tooth surface mixed with the grains, or applied alone and the grains subsequently dusted on. The tooth may be subjected to a first firing before application of the coating, the second firing being at a lower temperature.  A grain size from 25 to 1410 m , and especially from 100 to 200 m  may be employed.  The vitrified surface may be treated in the cold with hydrofluoric acid, or with ammonium acid fluoride.  In the manufacture of crowns and inlays, the platinum mould upon which the porcelain is fired may be coated over an area corresponding to the sealing surface with a thin layer of porcelain mixed with alumina. Flat teeth, without pins, may have the area of the flat surface increased by grooves.  The Specification as open to inspection under Sect. 91 refers also to the incorporation of the alumina with the porcelain, a volumetric ratio of 1:2 being specified.  This subject-matter does not appear in the Specification as accepted.

Filed: 1918-12-30
Abstract: 136,309. Alexander, A. E., (United Filters Corporation). Dec. 30, 1918. Rotary filters.-In rotary disk filters, means for inflating the filtering-units are provided in combination with scrapers for removing the cakes. A tank is used, one portion of which forms a single receptacle for all the disks, while the other portion is divided into chambers each of which accommodates one of the disks. The disks may be built up of separately detachable sections. As shown ir. Fig. 4, a disk section 1 comprises a rigid frame holding a body of wirecloth, corrugated iron, vitrified tile, &c., and surrounded by a filter-bag, the loose edges of which are lapped over the outer rim and held by angle-iron clamps 9. Clamps 5 on radial bolts 4 press on the clamps 9, the pressure being communicated to a nipple 8 through which the filtrate is passed from the section to one of a series of pipes 2 mounted on the axle B. The inner ends of the bolts 4 screw into a spider collar and press on clamps 7 which hold the pipes 2 in position. The filtrate passes away at either end through a ported piece 11, Fig. 5, tapered within a housing 12 having chambers 23 with separate outlets for filtrate and wash water, and an inlet 24 for compressed air. The tank of the apparatus is formed on one side by a quartercylindrical part D, Fig. 3, and on the other by a series of recesses E, each of which accommodates a single disk. The cakes formed on the disks are sprayed with water from pipes 19 as they rise from the tank, and they are removed by flexible scrapers 33, which direct the solid matter to fall between the recesses E to a receptacle or conveyer below. The material to be treated is supplied through a pipe 18. Pipes 16, triangular in section and located between the filter disks, allow of a circulation overflow. The tank may be provided with a cover which may be formed of roll curtains. In a modification, the pipes 2 are formed within the shaft B or replaced by a single conduit within the shaft.

Filed: 1954-07-27
Abstract: 758,785. Electric correspondence control systems. SOC. NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION. July 27, 1954 [Aug. 28, 1953], No. 21851/54. Class 40(1) [Also in Group XXVI] The area of the, nozzle of a propulsion rocket supported for axial movment on the craft it is to propel, is varied automatically in accordance with the value of the thrust. This is achieved by thrust measuring means arranged between the rocket and the craft and adapted to adjust the relative positions of the nozzle and a body associated therewith. In Fig. 1 a rocket motor 1 is mounted on rollers 4 for longitudinal movement in a guideway. A fixed rod 8 carries a bulb 9 which co-operates with the nozzle 2 to determine the effective area. The thrust on the wall 7 against the springs 6 determines the position of the nozzle relative to the bulb. In a modification, Fig. 2 (not shown), the bulb 9 is supported in the guideway 3 by profiled arms. In Fig. 3 a deformable device 12 acts on a device 13 so that it generates a voltage du1 proportional to the thrust. This is compared with a voltage du2 dependant upon the position of the bulb 9. The resultant voltage acts at 17 on a relay 18 controlling the rotation of a motor 19 adapted to shift a bulb. Various ways of obtaining voltage du1 are shown in Figs. 4-9 (not shown). In these respective modifications the movement of the motor produces variations in a rheostat, a potentiometer, a condenser, an inductance, a piezo-electric crystal, and a strain gauge

Title: Transmission channel equalization

Filed: 1973-05-09
Abstract: 1418576 Gain equalizers WESTERN ELECTRIC CO Inc 9 May 1973 [15 May 1972] 22074/73 Heading H4R The gain characteristic of a transmission channel 306 is equalized by at least one Bode network (such as in Fig. 1A) covering a predetermined frequency band, by transmitting over the channel pilot signals at the centre and two flanking frequencies in the band, determining the errors E(w) at these frequencies by comparison with reference signals 321, multiplying the error signals by the corresponding network gains at the same frequencies, summing the products, and adjusting the network to minimize the composite error signal. It is demonstrated mathematically that this procedure minimizes the mean squared error, and generally the flanking pilots are midway between adjacent band centre-frequencies. The network gains at the flanking frequencies may be actually measured, but it is sufficient to take pilot frequencies midway between the centre frequency and the boundaries of the frequency band at which the gains are ¢. The error signals E(wa) to E(wg) are therefore summed by resistors 330-339 of which 330, 333, 336, and 339 are equal and half the value of the remainder. The summed error signals are integrated by capacitive-feedback amplifiers 360-363 and added at 350-353 to signals representing the gains of the respective networks 310-316 to generate a resultant signal to adjust the network gains automatically and simultaneously. In modifications, the networks are manually adjusted by an iterative process in which the gradients of the error signals are displayed and each network is adjusted in turn until the gradients are zero together. An initial setting is determined by adjusting the networks to zero at the centre frequencies only. The adders 350-353, integrators and resistors may be re,- placed either by summing junctions, or by a receiver synchronized to three pilot frequencies to generate the gradient signal automatically.

Abstract: 531,713. Magnetically operated locks. EAGLE LOCK CO. July 29, 1939, No. 22094. Convention date, July 29, 1938. [Class 44] In a revolving barrel lock which can only be released by the use of an appropriate magnetic key the outer fixed cylinder 5 and rotatable barrel 9 have longitudinal grooves 16, 17 which register in the locking position shown and house locking balls 18 which prevent rotation of the barrel. The balls are of magnetic material and are movable along the grooves by a magnetic key, the appropriate key moving the balls into register with a circumferential groove 19 so that the barrel may be rotated. The key 20 has a cylindrical portion 21 with an aperture housing a permanent magnet 23 disposed transversely at such a position that the balls are moved with the magnet to release position when the key is inserted. The magnet is hidden and retained by a sleeve 22. The key also has a projection 28 which passes through a lateral slot 29 in the keyhole in an outer cover-plate 11 into a recess in a terminal flange 10 on the barrel which is thereby turned when the key is rotated. The key may also have a projection which passes through a notch 26 of the keyhole. To ensure correct register of the grooves in locking position a spring-pressed ball 30 housed in cylinder 5 snaps into a recess in flange 10. There may be one pair of registering grooves or as shown. two pairs. The Specification also describes a modification with four pairs, the key having two magnets. Locking is effected by the magnet moving the balls out of register with the circumferential groove as the key is withdrawn. Variations of the lock are produced by different positions of circumferential groove and different relative angular dispositions of notch and slot 26, 29, with corresponding positions of magnet and projections on the key. Owing to the smallness of the magnets they must be of highly magnetic material and an alloy of aluminium, nickel and cobalt. known as "Alnico" is stated to be the most suitable.
