Title: Method of fabricating composite panels
Inventor: WEBSTER JOHN W
IPC: E04C2/14
Filed: 1964-08-12
Abstract: 1,075,862. Woodworking. D. B. FRAMPTON & CO. Aug. 12, 1964, No. 32921/64. Heading B5L. A method of fabricating a wood panel comprises forming a plurality of wood components 22 each having a longitudinal channel 56 in a side surface, disposing the components in sideby-side relationship, drilling aligned bores 30 through the components and channels, the channels forming with the confronting side surfaces passages for the release of cuttings from the bores at a plurality of spaced locations, and driving into the bores metal dowels 28 having crested spiral threads 34. The side surfaces of the components 22 are also formed with interengaging tongues and grooves and a slight concave camber 48, 50 so that when the components are pressed together, the outer edges are in close abutment. The bores are then formed by a drill 15 of a diameter BD equal to the pitch diameter PD of the threads 36 of the dowels, the channels 56 serving both as guides for the drill and as passages for the chips. The drilling is stopped short of the outer side surface 44 of the outer component 24 and the dowels are driven into the bores to press and hold the components together. The ends of the dowels are substantially square so that the dowels can cut into the bores and extend to the extreme end of the bores. The dowels are of light relatively soft metal such as aluminium alloy, magnesium or the like.

Title: Apparatus for orientation
IPC: E21B47/024
Filed: 1946-11-07
Abstract: 623,421. Magnetic tests and measurements. NAAMLOOZE VENNOOTSCHAP DE BATAAFSCHE PETROLEUM MAATSCHAPPIJ. Nov. 7, 1946, No. 33154. Convention date, Nov. 27, 1945. [Class 37] [Also in Groups XX, XXXVIII and XXXIX] To determine the orientation of a frame 7, 9, Fig. 1, relatively to the earth's magnetic field, two coils 1, 2, mounted on the frame and preferably at right angles to each other, are oscillated about a vertical axis, and the currents induced in them are recorded by oscillographs; the Specification shows that the angle D1 made by one coil with the earth's field can be written tan D1= C E1/E2 T1/T2, where C is a constant that can be determined by an initial calibration when D1=45 degrees, and E1, E2, T1, T2 are quantities measured from the record and indicated in Fig. 7. The coils 1, 2 are preferably oscillated by first energizing them with direct-current so that they tend to approach each other angularly, and then de-energizing them so that they oscillate at a frequency and amplitude dependent on the earth's field and the mechanical constants of the coils. The equipment may be attached to a seismograph in a bore-hole so as to determine the orientation of the seismograph, Fig. 3; the seismograph comprises a mass 43 pivoted at 45 and carrying a coil 39 co-operating with a magnet 47, so that earth vibrations produce relative movement between the coil 39 and magnetic system 47. Where a bore-hole is to be deflected, the orientation of the deflecting surface 83, Fig. 5, may be determined by the equipment being located in a housing 82 which is lowered so that a guide surface 93 is brought into register with the surface 83 by the action of a spiral rim 89. To determine the orientation of thedeviation from the vertical of a bore-hole, the known apparatus of Fig. 6 comprising light source 103 and level 105 which images the bubble of the level on a film 109, may be combined with the two coils 1, 2 to determine the orientation of the level; alternatively, a mass 113, Fig. 8, may act on levers 112, 117 pivoted at 110 to vary the tension of the suspensions of the coils proportionally to the deviation from the vertical, and the deviation calculated from the change in frequency of oscillation of the coils.
