Title: Improvements in or relating to trichloro-silane-dienes
IPC: C07F7/12
Filed: 1954-05-28
Abstract: A polymer of cyclopentadienyl siloxane is prepared by reacting cyclopentadienyl trichlorosilane (see Group IV (b)) with isopropyl alcohol and hydrolysing the tri-isopropoxysilane.  It forms hard adherent films on glass.ALSO:The invention comprises trichlorosilane-dienes which have a trichlorosilyl group attached to a methylene carbon atom between two double bond groups.  They are prepared by reacting silicon tetrachloride with an alkali metal salt of a diolefin in a liquid hydrocarbon medium at temperatures of from - 25 DEG  to 100 DEG  C., in the absence of moisture and oxygen. Cyclopentadiene is the preferred diene yielding the product cyclopentadien-2,4-yl-1-trichlorosilane.  Some dicyclopentadienyl derivative is also produced.  The compounds form adducts with maleic anhydride, which contain carboxyl groups and which may be hydrolysed and neutralized.  Heating the cyclopentadienyl trichlorosilane between 75 DEG  and 200 DEG  C. produces a polymer which is mostly a dimer.  The trichlorosilane may be reacted with isopropyl alcohol to form the tri-iso-propoxy derivative which may be converted to a siloxane.  The compounds are useful as film-forming materials and as binders.ALSO:Porous material useful as insulating material is prepared by mixing equal amounts of sawdust and cyclopentadienyl trichlorosilane, slightly pressing together and heating for 15 minutes at 150 DEG C., when a coherent mass is obtained which may be shaped into blocks &c.

Title: Improvements in and relating to Wheeled Gun Carriages with Wide Firing Range for Artillery.
IPC: F41A23/32
Filed: 1914-07-01
Abstract: 119,664. Compagnie des Forges et AciÞries de la Marine et d'Homecourt. July 2, 1913, [Convention date]. Field carriages.-Relates to carriages with divided trails, the members of which are spread apart in the firing position, but are brought together for limbering-up. According to the invention, the effective length of the trail is reduced when the members are swung together, by a combined longitudinal and pivoting movement. In the form shown in Fig. 1, each trail member 6, 7 has a pin 27 which, in the firing position, shown in full lines, engages in a longitudinal groove 28 in the end of the rigid part 23 of the trail, and each member is locked by a cut-away bolt 35. When the bolt is rotated to the release position, the trail member is swung around the pin 27 until a rib 29 is alined with the groove 28. The trail member is then slid forwards until the rib 29 has passed through the groove; a further swinging movement is then possible about a second pin 26 which has passed into the groove, and the rear ends of the trail members are thus brought together. An undercut groove 32 in each trail member passes over a lug 33 on the axle so that the trail members are coupled directly to the axle. The successive positions, of the right-hand trail member 7 are shown at I, II, III, and IV. Alternative means for obtaining the combined forward and pivoting movements of the trail members are described in which a short link is introduced between each trail member and the connecting- piece 22. One such modification is shown in Fig. 8. The short link 34 is pivoted at 46 to the trail member 6 and at 47 to the connecting-piece 22. In the firing position I a locking-pin 48 passes through the three members 34, 6, 22. When the pins 48 on each side are removed, the trail members can be brought together by moving them through position II to position III, each trail member being then coupled to the axle by a pin 49.

Abstract: 112,012. Giot, H. L. V. D. Dec. 12, 1916, [Convention date]. Spherical - trigonometry calculators.- The time of transit of stars is determined, and those upon any required hour circle are identified, by means of a star map and relatively adjustable circular scales of right ascension and date. Within an annular ring a, graduated in time on the edge c, from 0 to 24 hours, is an adjustable rotary disk b bearing a projection of the stars of one polar hemisphere and of the declination-belt of the opposite hemisphere up to 40 degrees declination. The edge d of this disk is also graduated in time from 0 to 24 hours, against which are placed the dates e, f of the year upon which the true and the mean suns have the right ascensions shown upon the time scale. Radial arrows g from stars of first and second magnitudes indicate their right ascensions, and the declinations for a given epoch, with the variations for both, are given. If the date of the year be brought opposite zero upon the outermost scale, the reading against the radius from any star to the same scale will indicate the true or mean local time of the star's meridian passage, according to which date is set. A slotted radial pointer m, bearing a declination scale, enables the meridian zenith distance of a star to be reckoned if the latitude is known. A similar projection and scales for the opposite hemisphere are provided upon the opposite face of the apparatus.

Patent GB-166800-A (GB)
Title: Improvements in or relating to gyroscopic apparatus
IPC: G01C21/18
Filed: 1920-06-17
Abstract: 166,800. Gray, J. G. June 17, 1920. Addition to 130,697. Gyroscopic apparatus, -- In apparatus as described in the parent Specification in which the axis of rotation of a gyroscope is erected into the vertical by the action of rotating masses, an auxiliary gyroscope is attached to the erector in such. manner that its axis of spin, or a component of spin, rotates with the erector, and so gives rise to a rotating gyroscopic couple. As shown in Fig. 1, the gimbal-mounted gyro-casing 1 has rigidly secured to it a frame 1<1> in which is mounted on bearings a shaft carrying an electric motor 8. Secured to the motor casing is a frame 14 carrying a shaft 12 on which are mounted vanes 16; the shaft 12 is rotated by gearing 11 from the motor. The motor rotates a fly wheel 10 which forms the auxiliary gyroscope. Mounted on the frame 14 is an electromagnet 20 bearing a non- magnetic fork 17, 17<1>, Fig. 2, which acts as a pusher and a check to a ball 18 adapted to roll on a circular track 19 secured to the frame 1<1>. Current is supplied to the motor and to the electromagnet by slip rings 9. The reaction due to the rotation of the vanes causes the whole system mounted on the bearings 7 to turn. The centre of gravity of the system is eccentric with regard to the axis of the bearings, the arrangement being such that the gravity couples due to this eccentricity normally balances the gyroscopic couple due to the rotation of the axis of the fly-wheel 10. When the axis of the gyroscope 1 becomes inclined to the vertical, the motion of the frame 14 &c. becomes space-periodic and an erecting couple is set up. The action of the erector may be cut out in the presence of horizontal accelerations by speeding up the motor 8 and closing the circuit of the electromagnet so as to lift the ball from the track. In the modification shown in Fig. 4, the motor 8 is pivoted at 116 in a fork 119 capable of rotating in the bearing 7. The motor drives a fly-wheel 10 and also drives, through gearing 111, a shaft 112 bearing a roller 113 which is pressed down on to the track 117 by a spring 118. The erector may be cut out of action by speeding up the motor 8. In a modification of this construction, the pivoted motor and By-wheel are replaced by a small gyroscope pivoted in the fork 119. The casing of the auxiliary gyroscope carries an arm in which is mounted the roller 113, and the shaft 115 is slowly rotated by a stationary motor. The roller 113 may be replaced by a spring-urged brusn. In the further modification shown in Fig. 7, an auxiliary gyroscope 210 is mounted on a vertical shaft which is rotated through gearing in the casing 209 by the motor 8. The casing of the gyroscope is so attached to the shaft that the axis of the gyroscope is inclined to the vertical at a small angle. The gyroscopes 1, 210 are rotated in the same direction and the casing of the auxiliary gyroscope is eccentrically loaded by a weight 211.
