Abstract: A container (10) disclosed includes a unitary receptacle (12) and a unitary cover (14) which are each molded from resilient plastic with segmented buttress retainers (24, 32) that cooperate to secure the cover upon a snap action closing movement while permitting opening cover movement by manual rotation. The container has particular utility as a paint pail for holding paint, stain, or the like but is also useful for holding food or other contents. Downward cover movement slidably engages inclined flanks on the retainers (32) of the cover with inclined flanks on the retainers (24) of the receptacle to provide the snap action that engages horizontal retaining flanks to secure the cover while permitting subsequent opening movement by cover rotation.

Abstract: A latch operating lever (50) is mounted on one panel of a cassette or the like. The latch lever (50) has a hook portion (48) at one end which is held between a lip of the other panel and a latch plate (28) secured to and spaced from the lip. The latch plate (28) has a hinge bar (38) over which the hook portion (48) is mounted, and an opening (40) below the hinge bar (36) through which the free end (60) of the hook portion (48) extends.

Inventor: BIENEK HEINZ ING GRAD
IPC: G21F9/36
Filed: 1981-11-02
Abstract: It is known for the purpose of reducing the length of a spent fuel rod firstly to introduce the fuel rod into a straight containment tube (4', 4'', 26) and then to deform the rod in order to reduce its length, by winding up the containment tube with the fuel rod included therein. This length-reducing process leads to difficulties in producing the storage vessels provided for storing the coils. To avoid these difficulties it is proposed to assign to the containment tube (4', 4'', 26) at least one deforming element (9), which covers a fuel rod section of prescribed sublength in a sleeve-like fashion, is connected to the containment tube in a gas-tight fashion and remains gas-tight under deformation, and to bend the fuel rod by essentially 180<o> in the deformation region determined by the deforming element, the deforming element being deformed in accordance with the bend, and the containment tube remaining rectilinear over a substantial part (4', 4'') of its length. In this process, the deforming element can be constructed separately or can be a one-piece component of the containment tube. In the latter case, the cross-sections of the deforming element and containment tube can be equal. (See Figure 7a).   <IMAGE>

Abstract: A fastener for a shoe which is particularly useful for handicapped people who do not have use of their hands is disclosed. I am not aware of any fastener for a shoe which can be easily unfastened without use of the hands. 
     The invention includes a lever (30) fastened to a first portion of a shoe and a securing member (26) secured to the opposite side of the shoe. The securing member (26) is connected to an intermediate portion of the lever (30). The lever (30) is pivotally coupled by pivot (34) to the shoe so that when the lever is in the closed position the securing member (26) is below the pivot (34) to fasten the shoe to a user's foot. To open the fastener the lever is forced upwardly until the securing member (26) is forced over pivot (34). The lever may then swing all the way open to allow.the foot to be removed from the shoe. 
     The lever (30) may be of sufficient size so that it can be engaged and operated by a user's foot thereby not requiring use of the hands.

Abstract: A process and apparatus for the production of webs of fibrous cellulosic material combine defibering of moist cellulosic material with dry-forming of a web of the defibered material and subsequent press-drying of the web. Hence, defibered cellulosic material having a moisture content, for example, of from 30-40% by weight, is dry-formed to produce a non-woven web which is then consolidated by feeding it through a press-drying stage. In the press-drying stage, the web is advanced through a plurality of heated pressure nips (13) provided between a rotating heated cylinder (14) and cooperating pressure rollers (15). The web (16) is retained in contact with the heated cylinder between the pressure nips by means of the forming band (11) on which the web is initially dry-formed and which is advanced through the nips together with the web.

Abstract: Methyl tert-butyl ether (MTBE) is prepared by the selective reaction of methanol with isobutylene contained in a hydrocarbon fraction with four carbon atoms (C 4 fraction, or C 4 hydrocarbons), operating in the liquid phase under the influence of acid catalysts. The reaction mixture containing MTBE together with methanol and C 4 hydrocarbons is distilled, preferably at increased pressure, with separation of the methanol and the C. hydrocarbons at the head and of MTBE at the bottom of the distillation column. This operation is carried out with an additional lateral liquid flow of a C 4  hydrocarbon, or mixture of C 4  hydrocarbons, to the column so as to maintain a methanol-C 4  hydrocarbon composition in the column at all times with a greater than azeotropic C. hydrocarbon content at the operating pressure. 
     According to a preferred embodiment the distilled C 4  hydrocarbons, after separation from the methanol, are recycled as the lateral flow to the distillation column. It is thus possible to separate MTBE completely in a single distillation operation with a high purity as the product at the bottom of the column.
