Abstract: Provision is made to design the two armature discs (1, 2) of the clutch/brake combination as part of a one-piece double-armature disc, the armature discs being connected firmly to one another by means of tie webs (4), but being separated from one another by a radial gap (3). The resilient webs for connection to the primary or secondary part of the clutch are attached to arms (6) which project radially inwards from at least one of these armature discs and which are of such dimensions that the part of the radial gap facing them serves as an inlet orifice for cooling air flowing radially outwards. The invention is used for control devices of weaving machines. <IMAGE>

Abstract: A dual-purpose lottery play ticket and boarding pass (10, 30 and 50) issued by a commercial passenger carrier to each passenger boarding an aircraft for commercial flight. The invention comprises two parts, the first part (14, 34 or 54) of which is to be retained by the air carrier upon boarding, while the second part (12, 32 or 52) of which is to be retained by each passenger. Both first and second parts include data (16/18, 36/38 and 56/58) printed thereon describing each passenger by name and/or frequent flyer number, and information defining a particular schedule flight designation. Both parts also include identical lottery play indicia (20/22, 40/42 and 60/62) printed thereon so that each passenger has the opportunity to enter a lottery sponsored by the air carrier. By each party retaining a properly validated part of the invention, proof of entry and selection is secured. The preferred form of the invention (10) envisions each passenger making a lottery number selection in conjunction with boarding the aircraft; however, a random lottery number selection may also be preprinted on each part (32/34 or 52/54), random number selection thereafter by the air carrier still determining winners in either event.

Abstract: The present invention involves a novel tripyrrole dimethine-derived "expanded porphyrin" (texaphyrin), the synthesis of such compounds, their analogs or derivatives and their uses. These expanded porphyrin-like macrocycles are efficient chelators of divalent and trivalent metal ions. Metal complexes of these compounds are active as photosensitizers for the generation of singlet oxygen and thus potentially for inactivation or destruction of human immunodeficiency virus (HIV-1), mononuclear or other cells infected with such virus and tumor cells as well. A variety of texaphyrin derivatives have been produced and many more are readily obtainable. Various metal (e.g., transition, main group, and lanthanide) complexes with the texaphyrin and texaphyrin derivatives of the present invention have unusual water solubility and stability which render them particularly useful. These metallotexaphyrin complexes have optical properties making them unique as compared to existing porphyrin-like or other macrocycles. For example, they absorb light strongly in a physiologically important region (i.e. 690-880 nm). These complexes also form long-lived triplet states in high yield and act as efficient photosensitizers for the formation of singlet oxygen. These properties, coupled with their high chemical stability and appreciable solubility in polar media such as water, add to their usefulness.

Abstract: A detachable string of inflatable bladders (14/114), which are closed at one end in each case (22/122) and are partially closed at their other end (24/124), is vented by detaching their closure stoppers (16/116) in order to reduce their packaging volume for return transport or storage. In one embodiment, the continuation (16) of the stopper at the closed end (22) of each bladder (14) also forms the coupling with the filling and venting passage (18), at the end (24) which is partially closed thereby, of another bladder (14). In a second embodiment, the closed end (122) of a bladder (114) bears a loop (127) into which the closure stopper (116), attached by the bearer (125) to the partially closed end (124) of another bladder (114), is detachably inserted as a coupling. In this case, the venting of the bladders (114) is possible without detaching the coupling and closure of the bladders (114) is only required for renewed use. For rolling up again (11), individual bladders (114) are inserted with their closure stopper (116) into the loop (127) of the bladder (114) which was rolled up last in each case. During use, the bladders (14/114) are used as universal object protection padding for packaging, in transport or storage containers.   <IMAGE>
