Patent EP-0364098-B1 (EP)
Inventor: GAROFF THOMAS
IPC: C08F4/02
Filed: 1989-09-11
Granted: 1994-05-04
Abstract: The present invention relates to a method for the preparation of a reactive carrier for a Ziegler-Natta type polymerization catalyst. In the prior-art carrier preparation methods the focus has been mainly on improving the reactivity of the carrier by grinding or on preparing the carrier in specific reactivity-enhancing conditions, but the methods have been expensive and the results have not always been satisfactory. In the present invention, the reactive carrier is prepared by   a) causing the untreated carrier and a substance complexable with it to react with each other in order to form a particulate, thermally decomposable complex compound or complex salt, and b) treating the thus formed complex compound or complex salt with heat in order to separate the complexable substance in part or completely from the carrier, which is thereby rendered reactive. f

Title: A sizing composition, a method for the preparation thereof and a method of use
IPC: D21H23/26
Filed: 1989-06-20
Granted: 1993-01-13
Abstract: The present invention relates to a novel sizing composition in the form of an aqueous emulsion comprising a hydrophobic cellulose reactive sizing agent and a cationic polymer comprising a starch, the novel features of said composition being that the starch possesses a combination of (A) a branched, high molecular weight structure as reflected by an amylopectin content of at least 85% and (B) a degree of substitution of about 0.05 to 0.40. Such sizing compositions can be prepared by dissolving the aforementioned starch in water, adjusting the temperature to above the melting point of the sizing agent and adding the sizing agent to the solution so as to form a coarse emulsion , which is subsequently subjected to shear forces to reduce the particle size of the emulsion. The invention also relates to a method of preparing sized paper or paperboard by using the above-mentioned sizing composition. Also, the invention relates to the sized paper for paperboard prepared by said method. Such paper products show reduction in liquid absorbency as compared to products using conventional sizing agents, reduced consumption of optical highteners, and enhanced development of sizing.

Granted: 1993-01-07
Abstract: A countercurrent swimming pool is specified which serves, for example, for swim training for high-performance sportsmen. The countercurrent swimming pool has a swimming channel (1) through which water is to flow, a return flow channel (2) and a pump device (3) which takes in water from the swimming channel (1) and resupplies it to the swimming channel (1) via the return channel (2). With the aim of achieving a flow through the swimming channel (1) that is as free as possible from turbulence, the outlet opening (4) of the pump device (3), which radiates essentially vertically upwards, opens into a tower (5) which is arranged thereabove and which is connected in terms of flow to the swimming channel (1) via an acceleration section (6). The increasing of the initial flow velocity of the circulating water is served by the acceleration section (6), which tapers in cross-section in the flow direction. <IMAGE>

Abstract: Subliminal sound recordings are produced, in which, in addition to the use of a primary carrier such as music, two sound channels are used to supply subliminal messages to the brain. On one channel which stimulates the left cerebral hemisphere, the supplied message comprises meaningfully spoken, forward-masked, enabling affirmations delivered in canonical fashion by a male voice, a female voice and a child's voice. On the other channel, which stimulates the right cerebral hemisphere, instruction messages are recorded with backward masking (or in metacontrast) using the same voices. The three voices are recorded in canonical fashion with full echo/reverberation effect. The sound tracks are mixed using a special processor which converts sound frequencies into electric pulses and controls the synchronisation of the subliminal message in stereo with the primary carrier. The processor maintains a constant level differential between the primary carrier and the speech of the subliminal message and ensures, especially since the subliminal message is recorded in canonical fashion with full echo/reverberation effect, that nothing is lost from the message. The primary carrier should consist of continuous music without pauses and without significant differences in movement.

The output signals of the multipliers are then summed (94) and the result is processed by a single transversal filter (100) whose transfer function is determined adaptively.
