Title: Improvements in controlled wave energy generators
IPC: H03J7/04
Filed: 1949-07-28
Abstract: 662,505. Automatic frequency control systems. RADIO CORPORATION OF AMERICA. July 28, 1949 [Aug. 30, 1948], No. 19884/49. Class 38 (iv). Apparatus for generating oscillations and for controlling the frequency of the generated oscillations include a valve 10 which has an additional reflector electrode 14 arranged to influence the path followed by electrodes from the cathode 16 which pass through an aperture in the anode 12, the potential on the electrode 14 determining the transit time of electrons with respect to the cathode and anode and consequently the frequency of oscillation. Instead of the valve 10, pentagrid converters may be used by employing No. 2 grid as the anode and Nos. 3 or 4 grid as the reflector electrode depending on the type used. As applied to a frequency modulation receiver having a mixer MC, I.F. amplifier IFA and discriminator FDD, part of the discriminator output is fed through a M.F. filter Rg, Cf to the electrode 14. This output is fed in a sense such that the voltage or electrode 14 changes the frequency of oscillation to oppose the I.F. frequency change, thereby providing A.F.C.

Title: Glass manufacture
IPC: C03B15/16
Filed: 1975-05-13
Abstract: 1487446 Making glass STANDARD TELEPHONES & CABLES Ltd 13 May 1975 20080/75 Heading C1M A method of making a glass comprises forming a melt of one or some of the constituents of the glass, or precursors thereof, which melt may include one or more phases, and adding the remaining constituent(s) by at least one chemical vapour deposition reaction. The reaction may be a hydrogen-free reaction between a halide and oxygen, and may be employed to deposit Al 2 O 3 , As 2 O 3 , B 2 O 3  or SiO 2 . More than one oxide may be deposited either successively or simultaneously (e.g. P 2 O 5 , B 2 O 3  or As 2 O 3  may be co-deposited with SiO 2 ). A melt 13 may be formed in a silica crucible 12 which is disposed inside silica jacket 11, through which jacket 11 coolant nitrogen gas passes. The melt 13 is heated by r.f. induction coil 10 (which is water-cooled), the r.f. field coupling with susceptor 15. Crucible 12, susceptor 15 and alumina supports 14, 16 are all mounted so as to be rotated and/or raised or lowered by means of silica support 17. The susceptor 15 may be of graphite (which may be coated with silicon, silica or silicon carbide) or of silicon. Susceptor 15 heats the melt until a temperature of, e.g., 800-1000‹ C. is reached, when the r.f. field may directly heat the melt 13, the susceptor 15 then being removed. The constituent(s) to be added are supplied by passing a reaction mixture (e.g. halide vapour entrained in oxygen) through pipe 19 to just above the melt surface, where the deposition reaction occurs, the reaction being induced thermally or by the action of the r.f. field.

Abstract: 732,423. Earth-boring apparatus. NAAMLOOZE VENNOOTSCHAP DE BATAAFSCHE PETROLEUM MAATSCHAPPIJ. July 20, 1953 [July 21, 1952], No. 20091/53. Class 85. A well-drilling system comprises a tubular drill string having a rotary drill bit connected to the lower end thereof, with the interposition of a pair of mutually non-rotatable telescoping members consisting of a cylindrical member and a tubular plunger member mounted for limited sliding movement in the cylindrical member, and means for supplying fluid under pressure to the interior of the drill string, the telescoping members having an unobstructed axial bore therethrough, so that the load on the bit has two components the first due to the combined weights of the bit, the one of said members to which it is coupled and of any other members interposed between them, and the second a function solely of the fluid pressure drop prevailing across the jet openings provided in the bit. As shown, a housing 11 is secured to the lower end of a drill string 13, the housing carrying an inner tubular member 15 provided with a drill bit 17. Part 22 of the housing 11 is hexagonal in cross-section, the outer surface of the member 15 being similarly shaped, to prevent relative rotation. The member 15 has limited sliding movement within the housing and at the top has sealing means 23 for fluidtight engagement. The member 15 is extended within the housing 11 by pressure due to mud pumped from a pit 45 to the interior of the housing, the mud seeping through holes 30 in the drill bit and returning to the pit by way of the borehole 31. Above the borehole is a drill rig 20 comprising a crown block 32, a travelling block 33, a hook and swivel unit 34, fall lines 35 anchored at 36 and a weight indicator 37. The drill string is rotated by means of a rotary table 40 and its prime mover 41. A gauge 39 is provided for use when varying the pressure of the pump. A flow restricting device 46 may be provided on the pump discharge line for use with a gauge 47 for measuring the rate of flow through the drill string 13. Openings 48 may be provided in the housing 11 to allow escape of liquid into the borehole when the sealing means 23 has passed the openings, and so give an indication that the inner member 15 has been extended to its limit. In a modification the drill bit is secured to a housing which surrounds the inner member secured to the drill string. The apparatus may be used where the drilling takes place in a substantially horizontal direction.

As shown, Fig. 1, a thermoelectric module 1 is secured within a frame 7 of plastics material e.g. styrene-acrylonitrile copolymer by means of an insulating compound such as casting resin which also fills the gaps between the elements 3 of the module. The frame 7 has two U-shaped channels 10 at one edge in which are adhesively secured terminals 8 having their outer ends formed as flexible spills and their inner ends cranked on to the surface of the module where they are soldered to the end elements. The spills may be replaced by flat plug blades, Fig. 7 (not shown). The portions of the terminals within the channels may have apertures for the passage of the adhesive and the channel may be provided with studs which enter these apertures. The channels may be arranged to have a Z-shape in the plane of the frame so that the terminals are more firmly secured to the frame, Figs. 8 to 12 (not shown). The frame may be thinner than the thermoelectric module to allow the major surfaces of the module to be machined free of swarf without damaging the frame. The terminals may be in the form of Cu strips or may comprise stacked lamellae.
