Title: Improvements in or relating to spring suspensions for motor vehicles
IPC: B60G11/08
Filed: 1928-10-15
Abstract: 325,499. Wright, J. A. Oct. 15, 1928. Springs, arrangement of; lateral movement, preventing.-In a spring suspension system for motor vehicles, two or more transverse quarterelliptic springs secured to a central part of the framework or to a gear box are each provided with a rigid casing which encloses them and is pivotally connected to the framework and to a support or carrier for the road wheel. Excessive deflection of the spring causes it to make contact with one wall of the rigid casing so as to vary its effective length and the casing also supports the vehicle in the event of breakage of a spring leaf. In the example shown in Fig. 2, the casing consists of two channel-shaped members 9, 90 secured to one another and pivoted respectively to the frame or gear casing and the axle at the points 63, 64. Excessive deflection brings the master leaf 6 into contact with the lower part 90 of the casing. Two springs with casings arranged one above the other may be connected to forked portions of the wheel carrier or three springs may be arranged in a triangular manner as shown in Fig. 7. Reference has been directed by the Comptroller to Specification 120,093.

Title: Photographic printing and enlarging apparatus
Inventor: SEIFERT GERHARD
IPC: G03B27/72
Filed: 1965-07-14
Abstract: 1,062,07. Photographic copying apparatus. PENTACON DRESDEN KAMERA-UND KINOWERKE VEB. July 14, 1965, No. 29873/65. Headings G2A and G2C. In photographic copying apparatus in which a lamp is provided to influence the gradation of the printing paper by a below-threshold exposure, the lamp for this exposure is wired in series with a starting switch and a starting relay, which relay, when the starting switch is open, operates a twoway switch to complete a circuit through an indicator lamp. When the starting switch is closed, current flows through the lamp for exposure and the relay attracts the two-way switch to break the circuit through the indicator lamp. This circuit is not broken if the lamp for exposure has failed, and hence an operator observes that the indicator lamp is still alight, although the key has been closed. The exposure time can be preselected in accordance with the gradation required.

Title: Improvements in the manufacture and production of hydrogen peroxide
IPC: C01B15/023
Filed: 1935-11-04
Abstract: A tetrahydro-2-ethylanthraquinone is obtained by hydrogenating 2-ethyl-anthraquinone in organic solution with hydrogen at normal pressure in the presence of a nickel catalyst and oxidizing the solution of the resulting tetrahydro-2-ethyl anthrahydroquinone with oxygen.ALSO:Hydrogen peroxide is obtained by oxidizing aromatic compounds of the kind having hydrogen atoms which are readily split off and which on oxidation with elementary oxygen or gases containing the same yield quinoid or indigoid compounds, with oxygen or gases containing the same in a neutral or slightly acid or slightly alkaline medium and separating the hydrogen peroxide formed. Suitable aromatic compounds include indigo white, anthrahydroquinone and its methyl, ethyl, propyl, iso-propyl, chlor, or hydroxy substitution products, phenanthrene-, chrysene-, and retene-hydroquinones, or the nuclear hydrogenation products thereof, e.g. tetrahydroanthrahydroquinone and the corresponding quinhydrone-like molecular compounds.  A solution containing several of the said compounds may be used.  The substance need not be entirely dissolved, being suspended in part. The oxidation may be conducted at ordinary or increased pressure and at ordinary or elevated temperature.  The solvent may be one in which hydrogen peroxide is insoluble, e.g. benzene, toluene, xylene, or tetrahydronaphthalene, or may be one in which hydrogen peroxide (but not water) is miscible, e.g. amyl alcohol, cyclohexanol, methyl cyclohexanol or mixtures of the same with other solvents such as benzene or xylene.  In the latter case the hydrogen peroxide may be recovered by extraction with water.  The organic oxidation products may be reduced for re-use in the process. According to examples: (1) a solution of 2-methylanthraquinone in a mixture of benzene and cyclohexanol is reduced by molecular hydrogen at room temperature and atmospheric pressure in the presence of nickel, the nickel is removed by filtration from the resulting solution of the corresponding hydroquinone, the solution is shaken with oxygen at atmospheric pressure and the hydrogen peroxide is extracted with water; (2) a solution of 1-chloranthraquinone in benzene is reduced by sodium hydrosulphite in an atmosphere of nitrogen, the solution is washed with water and is shaken in the presence of water with oxygen at atmospheric pressure; (3) a solution of a tetrahydro-2-ethylanthraquinone (obtained by hydrogenating 2-ethylanthraquinone in organic solution with hydrogen at normal pressure in the presence of a nickel catalyst and oxidizing the p solution of resulting hydroquinone with oxygen) in a mixture of anisol and isoheptyl alcohol is reduced by hydrogen in the presence of active nickel, the reduced solution is shaken with oxygen, the hydrogen peroxide is extracted with water and the solution is recycled; (4) the process of example (3) is carried out employing a mixture of 2-methylanthraquinone, 2-ethylanthraquinone and tetrahydro-2-ethylanthraquinone.
