Abstract: 464,315. Gyroscopic apparatus. SCHNEIDER & CIE, and FIEUX, J. July 13, 1936, No. 19431. Convention date, Jan. 4. [Class 97 (iii)] The rotor 1 is rotatably mounted in a frame 2, 2<1>, and forms the driven element of a friction clutch of which the driving element 5 is rotatably mounted in a support 4 articulated to the frame 2, 2<1>. The latter may be pivoted to the support 4 about a single axis, as in Fig. 1, or, by means of a gimbal ring, about two axes at right-angles. The part - spherical driving element 5 is fixed to the spindle 9 of a motor 10 and is engaged by wipers 6 which are urged out of radial pockets in the rotor 1 by springs 7 and, under the influence of centrifugal force serve as speed regulators. The frictional forces between the element 5 and wipers 6 tend to precess the spin axis of the rotor into alignment with axis of rotation 9 of the element 5. In the form shown in Fig. 5, the support 4 is carried by a spindle 11 rotatably mounted in a main frame 12 and together with the gimbal ring 3 and frame 2, 2<1> is enclosed within the driving element 5 and rotor 1. The motor 13 drives the spindle 11 slowly through gears 16, 18, and the driving element 5, which is rotatably mounted on the spindle 11, more rapidly through gears 15, 17.

Title: Improvements in sighting devices for dropping objects from aircraft
IPC: F41G3/24
Filed: 1937-07-15
Abstract: 482,860. Bomb - dropping sights. OESTERREICHISCH UNGARISCHE OPTISCHE ANSTALT C. P. GOERZ GES., and RAABER, H. July 15, 1937, No. 19626. [Class 92 (ii)] Relates to bomb-dropping sights in which the time of passage t of the target between two lines of sight OA<1>, OA<2> is measured and used to determine either a third sight line OA<3> or a waiting interval t<w> giving the release angle or the release instant. According to the invention, the lines of sight are obtained by a horizontal bar 4 carrying at one end the fixed backsight O and at the other end two or three vertical bars 7<1>, 7<2>, 7<3> having different time scales on which the corresponding foresights A<1>, A<2>, A<3> are adjustable. The scales for the bars 71, 7<2> are graduated according to the time of fall T for the selected dropping height, using ratio factors c<1>, c<2>, respectively, the ratio factor c<3> for the third time scale being c<1>c<2>/c<2>-c<1> as proved in the Specification. By making c<2> = 2c<1>, a simplification is effected since then c<3>=c<2> and the third bar 73 may be dispensed with, the foresight A<3> being then adjusted on the time scale of the bar 7<2>. In using the apparatus, the timing foresights A<1>, A<2> are set to the time of fall T using the different scales on the bars 7<1>, 7<2> and the measured time t is used to set the dropping foresight A<3> on the bar 7<3>, or, if this is dispensed with, on the bar 7<2>. It is proved in the Specification that, when c<2>=2c<1>, t<w>=t-T, and this permits of using a reversible stop watch which is started at the sight line OA<1> and reversed at the sight line OA<2>, the bomb being dropped without using a sight line when the watch hand reaches a mark on the watch cover previously adjusted to the time T. To correct for drift, the bars can be adjusted about a pivot 6 to a slight backward inclination to the vertical, determined by a scale 7a.

Title: Weed-repelling propeller
IPC: B63H1/12
Filed: 1956-06-25
Abstract: 837,100. Screw propellers. LOISEAU, C. June 25, 1956 [June 27, 1955], No. 19652/56. Class 14. In a weed-repelling propeller having a hub and helical blades, all sections of the active face of each blade are concave as at C, Fig. 2, and offer within a portion of the planes adjacent the trailing edge the form of curves of which the tangent T at any point A of a segment of the curve is located on the left side of an observer lying along the axis O and facing the point, the sections being taken as rotating in the positive direction. The weed repelling faces are at the rear 3, Fig. 4, of the propeller 1 and the blades are of such length that the weeds are brought into contact with them and since a part of the curvature of the active face is such that it produces a centrifugal component AG in a plane tangential to the face, the water responding to this carries weeds &c. outwards away from the propeller. To achieve this the part is formed in accordance with the equation F (r, a, z) = O where r, a are polar coordinates in a plane perpendicular to the axis z when the equation fulfils the condition that r decreases as z increases.
