Abstract: Self-adhesive label with a suspension loop (1) which is fastened to its adhesive-free surface and made of a flexible film and of which a first region (1A) is firmly connected to the label (2) and a second region (1B) lies loosely upon the label (2). That surface of the suspension loop (1) which is turned towards the label (2) has a continuous adhesive layer which, in the second region (1B), is covered by a non-adhesive layer. As a result, manufacturing is simplified and the mechanical loadability of the suspension loop is increased. <IMAGE>

Abstract: A sustained relase aromatic composition comprises a clathrate compound composed of a perfume and a polyphenyl compound and gives out fragrance slowly but steadily over a long period of time. It is produced by a process comprising melting under heat a perfume which is a solid at room temperature, and adding a polyphenyl compound to the molten perfume. Alternatively, a perfume which is a liquid at room temperature is mixed with a polyphenyl compound so that they may react with each other, and a solid reaction product is separated from the resultant mixture.

Abstract: Novel membranes, useful for the separation of aromatics from mixtures thereof with non-aromatics, in, for example, a naphtha feed stream, are characterized by possessing a urea index of at least about 20% but less than 100%, an aromatic carbon content of at least about 15 mole percent, a functional group density of at least about 10 per 1000 grams of polymer and a C = O/NH ratio of less than about 8.0. These highly aromatic polyurea/urethane membranes are symmetric, dense film membranes made from the corresponding polyurea/urethane copolymers by standard membrane casting techniques. The polyurea/urethane copolymers are preferably produced by reacting dihydroxy or polyhydroxy compounds, such as polyethers or polyesters having molecular weights in the range of about 500 to 5000 with aliphatic, alkylaromatic or aromatic diisocyanates or polyisocyanates and low molecular weight chain extenders, such as diamines, polyamines or amino alcohols. 
     The membranes are useful for separating aromatics from non-aromatics in e.g., petroleum refining and chemical applications.

Abstract: In a process for isolating cellulose ethers, especially cellulose ethers with plastic properties and/or high flocculation point, from a cellulose ether suspension in which the cellulose ethers are separated out as filter cake by pressure filtration, especially in a rotary pressure filter, the intention is to avoid blockage of the separating device and for the separating device to have a long useful life. 
<??>This is achieved by carrying out the isolation in a rotary pressure filter (I) with a multilayer, preferably sintered, metal wire gauze (8) as filter medium, where the wire gauze (8) is formed from gauze layers of different wire thickness and/or mesh width, and by purifying the filter medium after removal of the filter cake with steam, compressed air or water under pressure.

Abstract: To create a displacement-flow with low turbulence, use is made of an air exit with a cylindrical or polygonal external housing (1). In the casing of the external housing (1), there are arranged nozzles (2) which are distributed over the housing circumference. Inside the external casing (1), an internal housing (3) is arranged, the casing of which consists of a perforated metal sheet or sieve. The internal housing (3) surrounds a core space (5) which is acted upon via a connection piece (6). In order to make the jets emerging from the nozzles (2) of low turbulence and emerge with low induction into the space, and to be able to vary in a simple manner the direction of the jets, there is mounted on the end side of the external housing (1) facing away from the connection piece at least one flap (8) which is pivotable about a pin (7). As the nozzles (2) are arranged in a plane close to the flap (8), the direction of the jets emerging from the nozzles (2) is influenced depending upon the position of the flap, as according to the degree of opening of the flap (8) a part flow by volume enters into the space directly, which influences the direction in which the jets emerge from the nozzles (2). <IMAGE>

Abstract: A machine tool for processing a work piece into a non-circular cross-sectional configuration according to the invention precisely processes, for example, a piston cylinder into a non-circular cross-­sectional configuration by inputting simplified data. 
     That is to say, a tool thereof is moved in a direction (X axis) perpendicular to an axis of the work piece by means of two servo motors. A first X axis servo motor operates to position the tool roughly in the X direction according to the size of the work piece. A second X axis servo motor finely vibrates the tool at high speed on the basis of program data. Since the displacement amount of the second X axis servo motor is fixed by working out the program data of a non-circular cross-sectional contour of the work piece through an automatic operation device, by inputting elements of the work piece in a simplified way and then storing the program data, the invention makes it possible to eliminate the inputting of the data to some extent and to process the work piece precisely and at high speed.

Abstract: A bicycle trainer has a horizontal frame. Pivotal hub capturing supports are attached to the frame. A bicycle wheel hub is situated between the supports where opposed hub capturing structure attaches to the hub and holds the wheel secure and upright. At least one of the supports has a quick release for capturing the hub. The quick release has a piston with a socket for fitting around the hub. The socket on the piston is urged towards the hub by a spring biased cam (20) having a lever (18) attached thereto. The structure supporting the rear wheel of a bicycle may be used to support the front of the bicycle. The rear and front wheel portions may be connected by a telescoping arrangement to allow for different lengths in bicycles. The rear tire rests upon and is in frictional engagement with a roller (2) attached to the frame. The roller is tensionable by way of a brake actuated with an easily accessible push-pull cable (12). The roller (8) supporting the front tire is not provided with a brake but is connected to the rear roller (2) by an endless belt (10). The quick release mechanism can capture a bicycle axle without removal of the nuts from the axle.

Abstract: A molten metal pouring nozzle for a continuous casting machine having an endless-travelling type mold, wherein the endless-travelling type mold is formed with two pairs of opposing wall members endlessly travelling in the same direction and at the same speed, and one end of the pouring nozzle is connected to a tundish for receiving molten metal, and the other end of the pouring nozzle is inserted into the mold. The molten metal pour­ing nozzle of the present invention comprises a nozzle body made of a refractory and a flow regulator made of a refractory. The nozzle body (14, 20) has a bore (1a, 3a), through which molten metal flows, along the axial line thereof, and the sectional area of the downstream end portion of the bore (1a, 3a) becomes gradually larger toward the downstream end thereof. The flow regulator (15, 18) is arranged at the center of the downstream end portion of the bore (1a, 3a) of the nozzle body (14, 20). The flow regulator (15, 18) forms, in cooperation with the bore (1a, 3a), a path for molten metal, by which molten metal flowing through the bore (1a, 3a) impinges   against the inner surface of the mold, near the downstream end of the nozzle body (14, 20).

Abstract: In a process for the production of microcapsules by coacervation of gelatin, carboxymethyl cellulose (CMC) and a second anionic polymer such as a polyvinylmethylether/­maleic anhydride copolymer or an ethylene/maleic anhydride/copolymer, the weight ratio of gelatin:CMC is chosen to be in the range 1:0.14 to 1:0.05, and the CMC used is chosen to have a viscosity in the range of from 50 to 140 mPas (cps), when measured in 6.0% by weight aqueous solution at 20°C using a Brookfield RVT viscometer, Spindle No. 1, 10 r.p.m. The use of the specified weight ratio and CMC type permits significant increases in the solids content at which encapsulation can be carried out without increasing process viscosities to an unacceptable extent and/or giving rise to poor quality microcapsules. The process is particularly suitable for producing microcapsules for use in pressure-sensitive copying paper.
