Abstract: 283,114. Aktiebolaget Svenska Kullagerfabriken. Jan. 3, 1927, [Convention date]. Addition to 262,144 and 269,559. Universal joints. - The wobbler coupling for a rolling mill described in the parent Specifications is further modified by making the neck 1 of the roll and the interior of the surrounding sleeve 3 of wedgeshaped cross-section, one side of the sleeve being detachable to facilitate assembling or disconnecting the coupling. The coupling-box 2 is provided at either end with recesses having curved lateral walls each recess accommodating blocks 4, 5 which are secured by screws 6 to the sleeves 3 enclosing the wedge-shaped ends of the roll necks 1. The side of the sleeve at the larger end of the wedge is closed by means of a detachable piece 7 retained in position by a spring catch 8. In a modification, shown at the righthand end of Fig. 1, the detachable side of the sleeve comprises a rotatable washer 9 which can be turned to engage recesses in the main part of the sleeve and locked by means of a spring 10. In assembling the coupling, the coupling box is first passed in an inclined position over one rollneck, Fig. 5, and is then swung over to pass the second sleeve over the neck of the other roll. This operation may be performed without interference from the adjusting-nuts 11.

Title: Improvements in and relating to apparatus for indicating the inclination of bore holes and the like
IPC: E21B47/022
Filed: 1934-01-02
Abstract: 411,775. Borehole clinometers. PAAR, W., Palenberg Bez, Aachen, Germany. Jan. 2, 1934, No. 167. [Class 97 (ii).] In a borehole clinometer, the amount of light passing from a source to a light sensitive device is controlled by a gravity operated device in accordance with the inclinatior of the apparatus. In the form shown, light from the lamp b is reflected by mirrors on to a photoelectric cell g. A tube m, rendered opaque from B to A and containing an air bubble and a quantity of liquid transmitting only rays which do not influence the cell g, e.g. a dark red liquid, is arranged in the path of the light so that the amount transmitted depends on the position of the bubble n relative to the opaque part of the tube m. The cell g is electrically connected to an indicating instrument at the top of the borehole. In a modification a metal cone carried by a plumb-line or pendulum is arranged to move over and mask a slot through which light passes from source to cell. Alternatively the cone may carry the light source. In a further modification, particularly for horizontal borehole, light from the source passes through a slit to a pendulous mirror, the position of which determines whether or not the light beam will pass through a slot to the cell.

Abstract: 160,949. Longshaw, F., and Allan, C. S. Jan. 3, 1920. Ball and float valves; floats.-In a ball cock having a screwed plug, such as 14, closing the upper opening in the casing, the plug is conically recessed at the bottom to receive the conical upper side of the valve 16, and a diverting lip 17 is formed in the inlet passage; these arrangements avoid an undue closing action of the fluid pressure and prevent water hammer. The float 11, which is adjustable along the float lever by means uf a screw 13, is hollow and its weight can be varied by the addition or subtraction of shot. The float lever may be jointed at 9 and capable of free movement through some such angle as is shown in Fig. 1. As the cistern 3 is filling, the float rises with the lever in the bent condition shown, but when the valve is nearly closed the water pressure on the top thereof quickly forces it down upon its seating and at the same time straightens out the lever. This arrangement gives a quick closing action to the valve without shocks.

Abstract: 551,773. Directive wireless systems. AGABALTIC AKTIEBOLAG, (formerly Aga-Baltic Radio Aktiebolag). Jan. 13, 1942, No. 515. Convention date, Jan. 13, 1941. [Class 40 (v)] In a wireless direction indicating system of the kind described in Specification 549,958, comprising an earthed screen 13 arranged between, and normal to, the halves 11, 12 of a dipole antenna, each half of the antenna being earthed alternately to provide two field diagrams the overlapping portions of which define the path, the screen is made substantially of optimum size, such that the angle at which the characteristic curve due to each half antenna, when the other is earthed, cuts the plane of the screen is as acute as possible in order that the path may be sharply defined. If the screen were indefinitely large there would be no coupling between the halves of the dipole and the characteristic curves 15, 16 due to each would lie wholly on its own side of the screen. If the length is decreased capacity coupling occurs between the halves of the dipole and the characteristic curves, for a particular dimension of the screen known as the critical value, become substantially symmetrical about the plane of the screen, and cut it at right angles. Further reduction in the length of the screen below the critical length at first causes the angle of intersection of the curves 17, 18 with the plane of the screen to diminish to a minimum, still further reduction causing the angle to increase owing to the loops tending towards the circular form 14 which obtains when the screen is not present. In an example, with an antenna formed of two copper pipes each 0.35 metres long and “ inch in diameter, a circular aluminium screen of about 1 metre in radius and # inch thick is employed. One or more reflectors may be provided to obviate the effect of radiation reflected from objects behind the beacon. Fig. 6 shows an antenna system comprising a quarterwave dipole 24, 25 ; a screen composed of tubular members 24 - 33 welded together, and reflector bars 34, 35, preferably somewhat longer than the dipole bars, connected to the screen. The screen members all lie in a plane perpendicular to the dipole and reflector bars. The reflector bars and the member 26 of the screen are respectively spaced about one-quarter and one-eighth of a wavelength from the dipole. In a similar arrangement giving a greater degree of sharpness to the indicated path, a pair of deflector bars is arranged in front of the dipole and at half a wavelength from it, the screen being extended forwardly and connected to these bars.
