Title: Improvements in or relating to piezo-electric resonators
IPC: H03H3/04
Filed: 1954-12-01
Abstract: 753,123. Adjusting piezo-electric resonators. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Dec. 1, 1954 [Dec. 4, 1953], No. 34768/54. Class 40 (8). A method of adjusting a piezo-electric crystal resonator to a desired frequency comprises rough-finishing the resonator to a frequency lower than the desired frequency, sealing the resonator within its envelope and providing an atmosphere inside the envelope suitable for the establishment of a flow discharge whereby material may be removed from the electrodes by sputtering until the resonator is brought to the desired frequency. The atmosphere inside the envelope may be of air or argon at a pressure of 500 microns. A negative voltage of 1500 V. with respect to the envelope is applied to the electrode terminals, metal from the electrodes being transferred to the envelope. If the envelope is non-metallic an internal or external anode is provided. Where it is desired to reverse the process and deposit material on the electrodes it is necessary to provide an internal electrode structure of the same material as the resonator electrodes.

Title: Improvements in nuclear fuel elements and a method of manufacturing such elements
IPC: G21C3/64
Filed: 1961-09-29
Abstract: 942,852. Nuclear fuel elements. BABCOCK & WILCOX Ltd. Sept. 29, 1961 [Oct. 7, 1960], No. 35159/61. Heading G6C. A nuclear fuel element is formed by dispersing the nuclear fuel, e.g. enriched U 3 O 8 , in a material which serves as an adsorber of gaseous fission products and then dispersing this material in a suitable thermal conductor. The adsorbing material specified is lead-free silica glass or quartz which is in the form of filaments or powder of diameter or particle size between 10 and 50 microns. The preferred thermal conductor is carbon, e.g. green graphite or carbon powder, which is mixed with the filaments or powder and a binder and moulded to a dimension slightly less than that required for the finished product and heated to approximately 1000‹C. The resulting body is then coated with carbon and a binder and sintered to a final shape at between 1200‹ and 2000‹C. When sintering takes place at above 1475‹C., a layer of silicon carbide is formed at the carbon-glass or carbon-quartz interface, and this layer assists in the retention of fission products.

Title: Induction regulator control for a.c. commutator machines
Filed: 1953-12-17
Abstract: 742,919. Control of A.C. motors. SCHWARZ, B. Dec. 8, 1954 [Dec. 17, 1953], No. 35182/53. Class 38(3) Relates to a polyphase commutator motor or self-driven frequency-converter having stator winding St and commutator C with fixed brushes, the machine being supplied from the divided secondary windings S1, S2, of a transformer T and controlled by means of an induction regulator having primary and secondary. windings PR, SR. The voltage of winding S1 between points 0, 2, is equal to that of winding S2 between points 0, 3, and the angle 2, 0, 3 in the vector diagram has a fixed value. The transformation ratio of the induction regulator is such that the voltage produced by the winding SR is substantially equal in magnitude to the voltages in windings Sl and S2, and the locus of its vector 'end 1 lies 'on a circle. The voltages applied to the winding St and commutator C are represented by vectors 2, 1 and 3, 1 so that a fixed phase angle is obtained between these voltages, both voltages changing their vectorial position simultaneously at different positions of adjustment of the regulator. In this manner, the coincidence of phase position of the commutator voltage and the regulating voltage applied to the brushes is' obtained by means of the induction regulator which has its secondary winding SR common to the stator and rotor circuits of the machine. The voltage derived from the winding S2 can be increased slightly so as to introduce a magnetizing component'.into the rotor circuit for. power factor correction and increase of stability and overload capacity of the machine. The primary winding of the induction regulator may be connected to the whole or a part of the secondary winding of the transformer, and the commutator brushes may be , fed through an additional intermediate transformer. In a modification, Fig. 3 (not shown), the rotor circuit only of the machine is fed by a transformer, the stator circuit being connected directly to the supply, and the induction regulator has separate secondary windings connected respectively in the stator and rotor circuits of the machine. In another arrangement, Fig. 4 (not shown), the transformer has separate secondary windings in the stator and rotor circuits of the machine. The induction regulator may be utilized also as a transformer, an additional secondary winding being included in the same slots as those accommodating the primary winding of the regulator and being connected in the rotor circuit of the machine, Fig. 5 (not shown). The rotor circuit of the machine may be arranged with three star-, connected phases, and the windings of the induction regulator may be replaced by one tapped winding providing an autotransformer connection, Figs. 5a, 5b (not shown).

Abstract: 358,781. Moulding-machines. ZIMMERMAN, G., 19, Lindemannstrasse, Dusseldorf, Germany. Nov. 22, 1930, No. 35245. Convention date, June 4. [Class 83 (i).] A machine for moulding sand or clay, having a dashpot 7, Fig. 2, for regulating the speed at which the pattern is lowered away, is characterized in that the liquid expelled from the dashpot cylinder passes through a passage 15 in the plunger 9. The plunger is formed in one with a hollow piston 8, working in a cylinder 6, and a support 10 for an adjustable plate 13. The pot 7 also communicates with the cylinder 6 by means of a passage 17, controlled by a hand-operated valve 16. The cylinder 6 may be mounted on a pivoted arm 3 which carries a jarring device 4 at the other end. The necessary liquid is placed in the hollow piston 8 and an air pipe 19 is arranged in the end of the cylinder 6 out of reach of this liquid. The pipe 19 may be controlled by a simple cock but, if the plate 13 is used to apply pressure, it is controlled by a three-way cock connected to a compressedair supply and to exhaust. After the piston 8 has been moved down to press the material the arm 3 is inverted, the liquid 14 running through valve 16 and passage 17 into pot 7 and return of the piston 8 being prevented by toggle links 26, 27, Fig. 8. The valve 16 is then closed, entirely or to any desired degree, the pipe 19 opened to exhaust and the toggle pulled by handle 29 to allow the piston 8 &c. to fall slowly. The arm 3 is then returned to the original position, the valve in the pipe 19 being first closed. The passage 15 may have a regulating valve.
