Title: Artificial Jaws
Inventor: JOSEPH JOHN ALECKSON
IPC: A61C11/00
Filed: 1966-11-02
Abstract: 1,156,155. Artificial teeth. J. A. JOSEPH. 2 Nov., 1966 [20 April, 1966], No. 49225/66. Heading A5R. Upper and lower artificial dentures, each having a gum-conforming base (which bases may be out of contact with oral tissue located between and rearwardly of the canine teeth), are interconnected by a pair of artificial jaw elements, each jaw element comprising (i) a rigid elongated portion having one end rigidly anchored in the base of the lower denture and extending rearwardly therefrom, (ii) a rigid arcuate portion having one end connected to the base of the upper denture and extending downwardly from a rear end thereof, the arcuate portion terminating (at its end remote from its connection to the base of the upper denture) at a position spaced from elongated portion (i), and (iii) an elastically flexible portion in the form of a spring wire forming the only interconnection between the rigid portions (i) and (ii). The jaw elements bias the upper and lower dentures to a separated position; the elements may have undeformed dimensions such as to span the dentures and to bias them to a position in which they are separated by a distance in excess of their spacing in the normal open-mouth position of the wearer. Each rigid portion of each jaw element preferably includes a laterally extending anchoring end, the anchoring end of the lower rigid portion being embedded in the base of the lower denture in forwardly (i.e. lip wise) spaced relation to the anchoring end of the upper rigid portion which is connected to the base of the upper denture. The flexible portion of each jaw element preferably is disposed rearwardly (i.e. tongue-wise) of the dentures in a plane common with the rigid portions. Each rigid portion may be made from a strip of metal interconnected by the flexible portion, which may be made of spring wire, in a common plane; the bases may be made of a metal frame and a curable rigid material, e.g. acrylic material, within which the anchoring ends of the rigid portions of the jaw elements may be embedded. Fig. 5 illustrates a pair of jaw elements 10 and 12, each element including an elongated lower rigid portion 30 terminating in a laterally extending anchoring end 32 which is embedded in gum-appearing acrylic material 28 supported by a lower denture 16 (see Fig. 2) comprising metallic frame 24 to which artificial teeth 26 are secured, an elastically flexible portion 34 made of spring wire, and an arcuate upper rigid portion 36 terminating in a laterally extending anchoring end 38 which is received within a hole in an upper denture 14 (see Fig. 2) comprising metallic frame 18 to which artificial teeth 20 are secured and which supports gumappearing acrylic material 22. In a modification illustrated in Fig. 9, the upper rigid portion 58 of the jaw element 56 terminates in a pivotal anchoring formation 60 through which a nail extends into the hole in the upper denture. The invention may be applied either to full denture sets, as illustrated, or to partial denture sets.

Title: Dynamic balancing in wobble disc devices
IPC: F01B3/00
Filed: 1977-11-29
Abstract: The piston engine has a swashplate (12), reciprocating pistons (2) and a shaft (23). In order to eliminate the oscillations occurring balancing masses are provided not only for the swashplate (12), but in addition also for the torque acting on the swashplate as a result of the acceleration and deceleration forces of the reciprocating masses of the pistons. A counter-torque is generated by torque balancing masses (28, 34), which are seated diametrically opposite one another on a hood (26), which overlaps the swashplate (12) and is rotationally fixed to the shaft (23). With this piston engine the outwardly acting forces occurring in its operation are entirely balanced out. <IMAGE>

Abstract: 1445724 Integrated circuits PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 7 Nov 1973 [10 Nov 1972] 51620/73 Heading H1K In a semiconductor device comprising two PIN diodes in series opposition, two surface regions 60, 61, Fig. 3, of the same conductivity type in a substantially intrinsic body 52 (e.g. with # > 50 ohm-cm and preferably > 100 ohmcm) are separated by the body from one another and from a low-resistivity region 62 (as shown, an encircling ring) of the opposite conductivity type; when operated with contacts 63, 64 to regions 60, 61 as respective H.F. signal input and output, the device provides a controllable impedance path for current which bypasses the contact 65 to region 62. Seven such devices comprising high-resistivity n-type Si bodies 52 .... 58, Fig. 2, mutually air-isolated and held together by insulating layers 67, 68 and metallization such as 7, 69, form, with resistors 59 formed in semiconductor material 51, an integrated 3-band-switch alternator circuit (Fig. 1, not shown). Surface regions 60, 62 are p-type, formed by diffusion or ion implantation, while low-resistivity region 62 is ntype. The beam-lead construction is formed as described in Specification 1,290,194. In a modification (Fig. 4, not shown) a high resistivity p-type Si body (81) extends beyond ntype surface regions (82, 83), but the more remote region (85) of the body is highly p-doped to provide a low-resistance current path bypassing a central contact (89) to p-type lowresistivity region (84), which both encircles and extends between the surface regions (82, 83). In manufacture, body (81) is doped on both sides with boron, the doped layer on one side being subsequently removed, as by etching, to expose a surface in which regions 82 .... 84 are then formed. After metallization, the device (or a plurality formed in a common body) is inverted and mounted on an insulating support (90); the body and the support may subsequently be divided.
