Title: Improvements relating to pliers for the production of anatomical tooth crowns
IPC: A61C13/12
Filed: 1924-11-20
Abstract: 226,788. Tryfus, F. Dec. 24, 1923, [Convention date]. No Patent granted (Sealing fee not paid). Pliers.-Relates to the manufacture of metal tooth crowns and consists chiefly in the use of pliers having jaws with recesses to give the crowns the desired shape in plan and with narrow portions of sufficient length to extend over the whole depth of the crown, including the root rim, and so shaped as to give the correct anatomical shape in depth to the peripheral portion or ring of the crown. The ring A is formed into the shape shown in Fig. 7, by repeated application of pliers, Figs. 4 and 6, having narrow jaws g, g<1> of the required longitudinal curvature. The jaws are shaped at their ends so as to prodace the root rim k. The jaw g is formed with a projection h overlapping the end of the jaw g<1> so as to serve as an abutment for the ring A. The general transverse shape of the ring is produced by compressing it within the lower recess i of the jaws as shown in Fig. 8. Local protuberances or recesses are produced by pressure on the ring whilst it is held in reversed position in the upper portions of the jaws of the pliers as shown for instance in Fig. 9. Fissures or sharp indentations are produced by means of a modified form of the pliers, Fig. 11, having a wedge-shaped projection m entering a recess n. Reference has been directed by the Comptroller to Specification 225,848.

IPC: F04B49/00
Filed: 1957-09-10
Abstract: 867,010. Rotating cylinder pumps. DREHMASCHINENWERK LEIPZIG VEB. Sept. 10, 1957, No. 28454/57. Class 102(1). A rotating cylinder pump having substantially radial cylinders comprises two pump units one of which has a constant eccentricity - while the second unit has at variable eccentricity automatically controlled in accordance with delivery pressure such that at a predetermined maximum delivery the eccentricity of the second unit is changed beyond zero to a negative value so that this unit operates as a rotor in such a manner that the oil displaced by the constant capacity unit is taken up by the second unit and returned to the sump thus providing a circulation of liquid for cooling the pump parts. The two pump units P1, P2 are arranged axially on a common shaft 4. Each pump comprises a rotating cylinder block housing two sets of substantially radial pistons. The pumps normally draw liquid from inlets 17, 24 and deliver to a common outlet 10. The pump P1 has a constant eccentricity e1 of its ring 8 while the eccentricity of the ring 7 of the pump P2 is variable between +e2 and -e2 in accordance with delivery pressure acting through conduit 11 on a piston member 16 against the action of a spring 9. Thus when the eccentricity of the unit P2 is negative this unit acts as a motor taking up the delivery of the pump P1 and returning it to the supply tank.

Classes 110(3) and 122(5) [Also in Group XXV] In an axial-flow elasticfluid turbine, an adjustable guide vane element is located radially of the turbine by means of an inwardly-extending spindle at the inner end of the vane which is supported in a footstep bearing, the vane element being resiliently loaded towards the bearing. In Fig. 1, the vane 1 has hollow spindles 5 and 6 secured thereto at the inner and outer ends. the inner spindle terminating in a conical pivot 15, for example of titanium carbide, which engages a footstep bearing 11 which may be of steel with a nitrided surface. The outer spindle 6 is mounted in a ballbearing 12, the race 12a being secured to the spindle, while the outer race is pressed inwardly by a spring 7, thereby urging the vane inwardly. The vane is adjustable by means of an activating ring 9 which' carries a pin 9a which engages a fork 8a at the end of the lever 8. One lever 8 has an extension 8b which is connected to an actuator link 20. A space 3f is defined around a conical portion 6a of the spindle 6 by rings 3a, 3b and cooling air is supplied thereto from inlet 39. A thin sealing element 13 is secured to the spindle 6 and engages the cover ring 17. In a second embodiment, the footstep bearing is afforded by a ball bearing and the sealing element comprises a number of concentric cylindrical portions joined at alternate ends. In Fig. 3, the footstep bearing comprises a single ball 23, which may be of titanium carbide, disposed between conical seats 24a, 24b. A conical seating in the end of the outer spindle 6 is engaged by a pivot pin 25, the pin being loaded by a spring 7. The sealing element in this embodiment comprises a number of cylindrical sleeves 29b joined together at their alternate ends. In a further embodiment, the cover ring 17 engages the spindle 6 and no other sealing means is provided for the space 3f.

Title: Improvements in and relating to repeaters for multi-channel communication systems
Inventor: BROWN WILLIAM THOMAS
IPC: H04B7/165
Filed: 1950-11-22
Abstract: 726,895. Radio signalling. BRITISH TELECOMMUNICATIONS RESEARCH, Ltd. Nov. 8, 1951 [Nov. 22, 1950], No. 28592/50. Class 40,(5). At a relaying station of a multiplex carrier communication system, an auxiliary channel is added by applying local signals to frequencymodulate the local heterodyning oscillator, use being made of the thermionic or other variable reactance normally provided for automatic frequency control. As shown, the incoming wave, which is frequency modulated by a wide-band multiplex signal, is received on an aerial 10, amplified at 11, and mixed at 12 with the output of a local oscillator 13 to provide an intermediate frequency for re-transmission the I.F. is amplified at 14, 15 and is raised to a different carrier frequency by mixing at 19 with the output of a further oscillator 20. A.F.C. of the oscillator 13 is provided by feetling the I.F. to a discriminator 16, and frequency-correcting voltages yielded by the discriminator are fed through a lowpass filter 17 to a variable reactor 18, which may be a valve reactor, to correct the frequency of the oscillator 13. Additional signals are applied to the reactor 18 at the terminal 23 and thus frequency-modulate the wave emitted and the aerial 22. These signals may occupy the band 300-3000 c/s., the multiplex channel signals occupying bands extending upwards from 9 kc/s. For receiving the additional signals at a relaying station, the output of the frequency discriminator 16 is fed through a filter 24 which rejects frequencies above 3 kc/s. The frequency control 18 may be of the reactance-switch type described in Proceedings of the Institute of Radio Engineers, January, 1951, page 41. Specification 625,486 is referred to. Reference has been directed by the Comptroller to Specification 623,741.

Filed: 1928-10-06
Abstract: 309,944. Baker, E. K. April 18, 1928, [Convention date]. Fluid-friction vibration-dampers.-Longitudinal movement between the frame and one end of a semi-elliptic spring is checked, preferably in one direction only, by a cylinder and plunger connection employing oil as the damping medium, the cylinder being carried by the spring and the plunger by the frame. One end of a cambered spring 2 is pivoted directly to the frame 1 and the other end is connected, as shown in Fig. 2, to the cylinder 8 of a damping-device which works on the plunger 5 rigid with the end of the frame 1. The cylinder 8 projects into and is integral with a reservoir 7 and its end is closed by a screwed plug 13 which contains a one-way passage 15<a> and a passage 19, 21 controlled by an adjusting-screw 22; the two passages connect the reservoir to the space between the plug 13 and the end of the plunger 5. Deflection of the spring until it is horizontal moves the cylinder &c. to the right without resistance, but further deflection and also the return movement are limited by the rate at which liquid can escape from the cylinder into the reservoir. The cup-leather packing 11 may be replaced by a stuffing box at the other end of the cylinder.
