Abstract: 388,628. Couplings for vehicles. WEIK, (nee KUHLMANN), E., 18, Himmelstrasse, Hamburg, Germany. June 13, 1932, No. 16671. [Class 79 (iii).] A trailer coupling-rod f is slidably housed in a sleeve h pivoted to a plate d on the tractor frame by a bolt g which passes through a longitudinal slot k in the rod. The baseplate d is positioned by a ridge e and secured to frame cross members b, c. The sleeve h is integral with a bearing plate l. A cushioning thrust block o within the rod is retained clear of the side walls by means of pins q on face-plates m, n, and is located between the pivot pin and an end block t, the plate m bearing against an annular ridge r and the assemblage being secured by a threaded closure member s. A vertical bolt v, mounted on the baseplate, is adapted to drop into a cavity in the end block t when the coupling rod is in alignment with the longitudinal axis of the vehicle, being normally urged downwards by a spring acting on a bell-crank lever x, y adapted to be withdrawn by a cable a<1>. When the bolt v is raised, the rod f is free to swing and slide to facilitate coupling. When the rod swings into alignment under the tractive pull, the bolt v drops into the socket, locking the rod against angular movement and then serving to take thrusts due to over-running &c. whilst the pivot bolt g takes the normal tractive pull.

Title: A process of preparing organosiloxanes
IPC: C08G77/00
Filed: 1948-06-22
Abstract: Polysiloxanes are prepared by reacting at least one alkali-metal salt of a di-organo silanol, in which the organic radicals are linked to the silicon atoms by carbon to silicon bonds, with at least one silicon halide, e.g. an organosilicon halide.  The reaction may be carried out in the absence of moisture, in the presence of a solvent e.g. diethyl ether, dioxane, petroleum ether, toluene, benzene or pyridine, and the desired siloxane may be separated from the alkali metal formed. The atomic ratio of silicon halide to alkali metal may be at least one.  The silicon halides that may be used contain at least one halogen attached to silicon, the remaining valencies being satisfied with halogen atoms, organic radicals, or siloxy radicals, e.g. SiX4, RSiX3, R2SiX2, R3SiX and X(R2SiO)n R3SiX, and where R represents an organic radical and X is halogen.  An organosiloxane, which may be subsequently further hydrolysed and condensed, is obtained by employing one of the reactants in excess.  A number of detailed examples are given.ALSO:Organosiloxanes are prepared by reacting at least one alkali-metal salt of a di-organo silanol, in which the organic radicals are linked to the silicon atoms by carbon to silicon bonds, with at least one silicon halide, e.g. an organosilicon halide.

Abstract: 162,304. Tripp, W. H. Oct. 15, 1918. Gyroscopic apparatus.-A turn indicator for aircraft comprises one or more gyroscopes 1 pivoted in a balanced ring 5 which floats on pivots 6 in a frame 7 secured to the aircraft, the pivots 6 being fore-and-aft and the whole pivoted system being in neutral equilibrium. The direction of spin of the gyroscope is over towards the nose of the aircraft as shown by the arrow, Fig. 2. Precessional motion of the ring 5 in response to turning of the aircraft is indicated by a vane 11 secured to the ring and is restrained by springs 10 acting on a pin 24 secured to the ring. The springs are secured to a support 19 carried by the frame 7 and can be adjusted by a slidable clip 22, Fig. 8. Precession of the ring 5 is limited by adjustable stops 9 which may be positioned to allow a total swing of about 160 degrees in order that the maximum effect may be produced when a steeply-banked turn is executed. By turning the whole apparatus in its own plane until the pivots 6 are vertical, the instrument may be used to indicate tilting. Auxiliary means for indicating tilting unaccompanied by turning comprise a pendulum 12 mounted on one of the pivots 6 and having an indicating-vane 13.

Abstract: 477,153. Photographic films. KODAK, Ltd. June 17, 1936, No. 16911. Convention date, June 19, 1935. Drawings to Specification. [Class 98 (ii)] A photographic film comprises an organic cellulose derivative support and a photographic gelatino emulsion, good adherence of the emulsion and high flexibility being imparted by the application to the base of a very thin substratum comprising a mixture of a colloid and a hydrophobic synthetic resin capable of adhering to the support and by the application between this substratum and the emulsion of a further substratum consisting of gelatine or a mixture of gelatine and a synthetic resin. If the colloid is gelatine, the second substratum may be omitted. The thickness of the very thin substratum may be À00008". The support may be of cellulose acetate, propionate, butyrate, acetate-propionate, acetate-butyrate, or acetatestearate, or may comprise a cellulose ester, for example, cellulose acetate of 90 per cent precipitation value, coated with a thin layer of a cellulose ester of lower precipitation value, for example, cellulose acetate of 69 per cent precipitation value. The colloid may be gelatine or cellulose derivatives such as cellulose acetate. Suitable resins are alkyd resins obtained by reaction between one or more polybasic organic acids and one or more polyhydric alcohols. The resin formed from glycerol and phthalic acid or its anhydride or the resins formed by reaction between a polybasic organic acid, an alcohol having three or more hydroxyl groups in the molecule, a dihydric alcohol, and a dibasic aliphatic acid may be employed. The substrata may be applied by immersion or by a roller. The substrata may be applied to the support on one side or, for example, in the case of X-ray film, on both sides. A non-curling layer of gelatine or other material may be applied to the opposite side of the support. Examples are given of the application to a cellulose acetate support of a gelatine-synthetic resin substratum, of the coating of a cellulose acetate support of 90 per cent precipitation value with cellulose acetate of 69 per cent precipitation value and then with a gelatine-synthetic resin substratum, of the coating of a cellulose acetate support of 90 per cent precipitation value with a substratum comprising a mixture of cellulose acetate of 69 per cent precipitation value and synthetic resin and then with a gelatine substratum, and the successive application to a cellulose acetate support of cellulose acetatesynthetic resin and gelatine-synthetic resin substrata.
