Title: Rear light cluster for car - with successive lights in sets illuminated at different speeds
Inventor: MAASSEN HANS
IPC: B60Q1/54
Filed: 1974-05-24
Abstract: The rear light cluster comprises reflectors, brake lights, direction indicators as well as red lights arranged in sets. The red lights are illuminated by a speed sensitive control. This monitors the vehicle speed, from e.G. the speedo cable drive, and illuminates the lights, which are all different, in sequence depending on speed. An alternate solution has progressively more lights illuminated with increasing speed. The following drivers can thus accurately judge the speed of the leading vehicle, even in poor visibility. The invention is especially useful for slow moving construction vehicles whose speed it is difficult to judge.

Title: Separation of anthraquinone from amino-anthraquinone - by treatment with inorganic acid and organic solvent
Inventor: OKADA TSUGIO
IPC: C07C225/34
Filed: 1974-07-15
Abstract: Crude amino-anthraquinone contg. unreacted anthraquinone is treated with inorganic acid, and previously, simultaneously or subsequently with organic solvent which dissolves the anthraquinone without affecting the amino-anthraquinone salt. The soln. is then separated from the solid salt. 1-amino anthraquinone with purity over 99% is obtained in almost quantitative yield, and anthraquinone with purity over 95% recovered without loss, and capable of recycling without purifcn. The process is simple and economic. The acid is H2SO4 and is used in amount of at least 1, pref. 1.5-4 equivs. per mol. amino-anthraquinone. The solvent is a chloroalkane, pref. tetrachloroethane, or is xylene or nitrobenzene. The anthraquinone is separated by distilling off the solvent, and the salt decomposed by adding to a large amount of water.

IPC: G05D11/00
Filed: 1974-11-12
Abstract: An apparatus for injecting metered quantities of fluids or gases into a streaming fluid, esp. dissolved chemicals into water for drinking or other purposes, consists of a spring-loaded baffle producing in the main fluid line a positive or a negative pressure gradient; a branch line taking a part of the main flow, and a vessel connected to the branch line by way of a metered flow line along which the metered additive is drawn by the action of the pressure gradient. The baffle is as is usual, linked to an adjustable needle valve which regulates the open section of the branch line. this is aligned coaxially with the main flow line and has a restriction into which the metered flow line opens. The needle valve has exactly the same conical form as ther outlet of the branch line acting as a diffuser, into which the valve needle projects. The baffle fits with its tapering bore on the outer contour of the diffuser and is displaced axially along its surface. Even with the smallest amounts of the additives, there is a constant interedependance of the metered quantity and the throughout volume which are directly proportional to each other.
