Abstract: FOAM-CONTAINING POLYURETHANE(UREA) COMPOSITIONS    AND   PROCESS FOR THE PREPARATION THEREOF               ABSTRACT OF THE DISCLOSURE This invention relates to polyurethane(urea) compositions which contain foam and which are preferably cationically modified, contain non-abrasively bonded fillers and have a very high water absorbability (WAF).         Production is effected by reacting iso-cyanate-terminated prepolymers with a quantity of water far exceeding the stoichiometric quantity in the presence of foams in particle or film form.  The reaction mixture may also contain lignite powder and/or peat, other inorganic and organic fillers and/or biomasses (living cells, living bacteria, enzymes).      The polyurethane(urea) compositions contain up to 95 % by weight of foam particles and may contain further fillers (preferably lignite and/or peat).  The compositions are swollen and have a high water content during production.  Their water absorbability (WAF) when suspended in water is  33 to 97 % by weight of water. They can be used as carriers in microbic synthesis processes for the production of complicated organic compounds (when they have incorporated biomasses) as special carriers for the growth of plants, as filter agents or as adsorbents for non water-soluble liquids [for example, crude oil or petrol].

Abstract: TITLE Coupling Clutch And A Self-Contained, Non-Removable Guard ABSTRACT OF THE DISCLOSURE     A coupling clutch according to the teachings of the present invention is shown in its most preferred form as including first and second hubs having first and second splined friction discs received thereon.  The first friction disc is biased away from the second friction disc and is movable towards the second friction disc by a piston reciprocally mounted to a housing and rotatably mounted to the friction disc by a bearing mounted there-between.  The second friction disc is substantially pre-vented from sliding on the splines with the second hub. The splines between the second friction disc and the second hub allow the second friction disc to cant to compensate for axial angular misalignment of the first and second hubs.  The guard is shown according to the teachings of the present invention in its most preferred form as including a plurality of ring members held in a spaced relation by bars.  The ring members have a shape complementary to and for receipt on a first shell of a housing.  The bars are received within apertures formed in the first shell and are captured therein when the second shell is secured to the first shell.  The guard is then self-contained, self-aligned, and cannot be removed without disassembly of the housing.

Abstract: ABSTRACT OF THE DISCLOSURE     The mixer tap has hot and cold water inlets, a water outlet, a valve mechanism controlling the relative quantity of hot and cold water supplied from the water inlets to the water outlet, and a noise attenuator for reducing the noise which could otherwise be generated upon sudden opening of the valve mecha-nism.  The valve mechanism comprises a fixed plate valve and a movable plate valve arranged in opposition to one another.  The movable plate valve is slidable relative to the fixed plate valve by a valve operating mechanism and has therein a water through flow chamber with a water inlet region at one end and a water outlet region at the other end.  The noise attenuator comprises a sound attenuating member of permeable metal construction and a support member which holds the attenuating member in firm contact with a wall portion of the chamber in the inlet region thereof such that water entering the chamber impinges upon or skims along the attenuating member.  The movable plate valve also has an escape groove which allows restricted escape of cold water to the chamber when the cold water inlet is fully closed and the hot water inlet is fully open.

Abstract: ABSTRACT     This invention primarily is directed to a hematology reference control solution, the three separate white cell control portions thereof consisting of three types of fixed red cells of determined size distribution for checking the operation of a particle analyzing instrument, including its predetermined lower and upper threshold settings for each class or subclass of leukocytes.    For preparing a human granulocyte analogue, nurse shark erythrocytes are altered and fixed in a chilled solution to simulate in number, size and distribution the granulocytes in human whole blood.    Such a granulocyte analogue is useful as a free-standing reference control, for determination of human granulocytes only, or can be comingled with reference controls for lymphocytes and mononuclear cells for use with multi-parameter instruments to give a trimodal leukocyte reference control, which itself can be included in a multiple-analysis hematology reference control, having components for also determining red blood cell and platelet parameters.

Abstract: ABSTRACT          Process for dewaxing heavy distillate and residual feed.          Easily converted waxes are partially removed in a first catalytic dewaxing step, and the resulting product is separated to remove the light ends.  The heavy liquid fraction, which contains difficult to convert waxes, such as poly-branched or mid-methyl branched paraffin waxes, is then introduced into a second dewaxing stage, where the liquid stream is dewaxed to a specification pour point.  The process may be implemented via double pass dewaxing in existing units or by passing through two consecutive dewaxing units.  Improvements are due to a decoupling of temperature requirements in each reaction step and removal of cracked products which inhibit dewaxing and accelerate aging in the second dewaxing stage.

Abstract: ABSTRACT OF THE DISCLOSURE         A method of and device for attaching a web of material rolling off to a processing machine to the beginning of a fresh web that is wound on a reel. To provide a method that will inexpensively and rapidly ensure a reliable attachment between the two webs, the first web is separated upstream of a stored section with the processing machine turned off and the separated section at least partly reserved, the section of web with the second web is then forced into contact, and the end of the reserved web section attached to the beginning of the second web as it arrives by releasing the reserved web section with the processing machine in operation. The device comprises an upright with the replacement reel mounted on it, a mechanism for reserving a supply of web, and a mechanism for cutting the web. To provide a device for carrying out the method that will be simple in design and universally applicable, a transfer mechanism that accommodates at least part of a separated section of the first web and that can be forced into contact with the outer surface of the replacement reel is positioned between the cutting mechanism and a reservoir.

Abstract: ABSTRACT          A method is described whereby asymmetric retroreflecting elements are positioned with their hemispherical sides pointing upwards, made to agglomerate in rows and then deposited onto the road surface or onto a road-marking strip.          The elements are passed over an inclined vibrating plane.          Those elements with their rounded sides pointing downwards towards the plane are considered unstable and thus the majority of these elements turn over to the more stable orientation with their flat surfaces on the inclined plane.          The elements are then grouped together on the surface of the plane and one or more bottom rows of the elements so grouped on the inclined plane sequentially discharged therefrom.

Abstract: METHOD FOR MANUFACTURING RIM COMPOSITES                  ABSTRACT OF THE DISCLOSURE    A polyurethane RIM method has two mixheads.  Reactants are brought to each mixhead and are supplied as separate streams to two spaced cavities in a mold having a pre-formed porous mat separating the two cavities.  One stream contains an isocyanate, polyol, chain extender and crosslinker selected to have a  very low viscosity and which reacts to produce a high modulus armature or load bearing member.  The other stream contains a polyol and isocyanate with additives that have relatively high viscosity to produce a semi-rigid polyurethane foam.  At each mixhead the proportions of ingredients are controlled to give a desired isocyanate index to control the flex modulus and other properties of the loading bearing member and foam molded components of the product.  The low viscosity material penetrates the porous mat to reinforce it and the porosity of the mat prevents the high viscosity material from entering the armature cavity so as to reduce the load capacity of the finished product.
