Title: Alkenyl benzene from alkylbenzenes and butadiene - with alkali metal catalyst
Inventor: IWATA KAZUMI
IPC: C07C2/72
Filed: 1974-11-12
Abstract: Improvement on the preparation of alkenylbenzenes by reacting alkylbenzenes with 1,3-butadiene in the presence of an alkali metal catalyst whereby the alkylbenzene is first contacted with the reaction product before reacting with 1,3-butadieno. The contact is pref. made at a point between leaving the reaction zone and the stage where unreacted alkylbenzene is recovered. Particularly by contacting the fresh alkylbenzene with a catalyst after the catalyst separation stage from the reaction product. This method gives improved yield, smaller quantity of catalyst required and simple operation.

Title: Cold cleansing compsns. for solid surfaces - contg. mineral oil fraction, petroleum sulphonate and acid phosphate with fatty alcohols
Inventor: RIEDEL WOLFGANG
IPC: C11D3/18
Filed: 1975-06-11
Abstract: New solvent- and surfactant-based cold cleansing compsns. contain (a) an esp. predominantly paraffinic or naphthenic mineral oil fraction, (b) petroleum sulphonate and (c) acid phosphoric acid esters with 12-18C fatty alcohols, esp. oleyl alcohol. Concn. of components (b) and (c) together is 3-10 wt.% w.r.t. total compsn. and the acid phosphoric acid ester is present in excess. The compsns. are used to remove oily and fatty dirt from solid surfaces, e.g. metals, cement, ceramic, glass and plastics. The compsns. can be used for cleaning machinery machine parts, vehicles, vehicle engines, transport containers and oily floors, at room- or slightly higher temps. The cleansers have good cleaning power and are easily rinsed off, e.g. by spraying with water. The water-cleanser mixts. or water-cleanser-dirt dispersions separate quickly into solvent and a clear aq. phase. Mineral oil fractions advantageously have flash point >55 degrees C. The petroleum sulphonates are obtd. by sulphonating lubricant oil fractions with SO3 or oleum. In an example, a cleansing compsn. was prepd. by dissolving 4% oleyl phosphate and 9.3% petroleum sulphonate having mol. wt. 430 in a paraffinic and naphthenic mineral oil fraction, b.pt. 182-212 degrees C.

Title: Call allotting system for telephone exchange - drops long waiting low priority calls in favour of higher priority calls
Inventor: AIGNER WALTER DIPL ING
IPC: H04M3/523
Filed: 1975-07-30
Abstract: The call allotting and stacking system, for a telephone exchange, allots calls by considering priority and waiting time. Incoming calls are assigned a priority and held in call and waiting registers in the order in which they arrive. They are read out of the registers in the same order as they were written in. The object of the invention is to give higher-rated calls priority over lower-rated calls by limiting the latter's waiting time to a maximum. This is achieved by dividing the call memory into segments and by allowing different segments to handle different priority calls. Long-waiting lower-rated calls are given priority only until a minimum time is reached between the longest-waiting call with a higher priority and the longest-waiting lower priority call.

Title: Magnetic field expansion and compression method - uses magnetic energy to modify grain structure and break strength of materials
Inventor: DAVIS ALBERT ROY DR
IPC: C22F3/02
Filed: 1976-06-18
Abstract: Physical properties of a material are altered by heating the material to a molten state then applying to the molten material magnetic energy in the range 1,000 to 1,000,000 gauss from only one magnetic pole for a time sufficient to achieve the desired alteration in properties. The material is then cooled to a solid state. The process is used to control the texture, grain, and surface condition of the cooled metal. For treating magnetic materials to enhance their ability to store data, magnetic bits, codes, information and the like. If the one magnetic pole is the north magnetic pole and the material treated is metal, the solidified metal exhibits an improved break strength and relatively finer grain structure. If the one magnetic pole is the south magnetic pole and the material treated is metal, the solidified metal exhibits decreased break strength and a relatively coarser grain structure.
