Abstract: Known kitchen or bathroom wall cabinets are formed by a cupboard body and one or more tabular surfaces and are closeable at the front by means of doors. When wall cabinets of this type are used in damp areas they absorb too much moisture, which has a negative effect on the connections of the individual parts of the wall cabinet. In order to overcome this disadvantage, a wall cabinet is proposed according to the invention in which cupboard body (1) and tabular surfaces (5) form an indivisible unit which is provided with a smooth surface and in which all transitions between cupboard walls (3) and tabular surfaces (5) are produced by means of fillets. The wall cabinet together with its tabular surfaces is according to the invention advantageously made of plastic, in particular a reinforced polyester material, which prevents any absorption of moisture. <IMAGE>

Abstract: A process is described for the production of substantially pure  gamma -butyrolactone from a feed mixture containing a major amount of  gamma -butyrolactone and a minor amount of diethyl succinate which comprises fractionally distilling the mixture in a fractionation zone in the presence of diethyl ethoxysuccinate and recovering from the fractionation zone an overhead vaporous product comprising  gamma -butyrolactone which is substantially free from diethyl succinate and a liquid bottom product comprising diethyl ethoxysuccinate and diethyl succinate in admixture one with another. This procedure can be used to separate a  gamma -­butyrolactone rich fraction obtained by distillation in one or more stages of a crude reaction product obtained by hydrogenation of a C₄ dicarboxylic acid ester feedstock that contains a major molar amount of diethyl maleate and a minor molar amount of diethyl succinate, using a diethyl maleate feedstock from an esterification plant to provide diethyl maleate for use as feedstock for the hydrogenation process which is admixed with recycled diethyl succinate recovered from the fractionation zone.

Abstract: It is highly desirable to reinforce the grassed surface layer of a sports ground in order to reduce damage to the surface, e.g. from horse racing or from playing football. In order to provide a good surface layer, a biaxially-orientated, integrally-extruded plastics material mesh structure layer is laid on a base of sand 2 strengthened with small, flexible, randomly-placed, plastics material mesh pieces. A top dressing 3 is put on top of the mesh structure layer, grass 4 is seeded or planted, and a machine is then used after the grass has grown to slit the mesh structure layer into pieces 1 which may be e.g. 100 x 100 mm or 150 x 150 mm, each having a number of complete mesh openings. If a piece 1 is caught by a horse's hoof or by an footballer's stud, it may be ripped out, but the whole mesh layer is not ripped out.

Abstract: Al alloy product containing lithium, of high specific mechanical strength and high tolerance to damage, in particular resistant to stress corrosion in the treated state (quenched-tempered), especially in the recrystallised state. 
<??>The products according to the invention exhibit a specific microstructure, with numerous fairly coarse precipitates of intermetallic phases rich in Al, Cu, Li, Mg and optionally Zn, whose volume fraction is between 0.6 and 4%. A differential enthalpic analysis test makes it possible to verify that the product has been treated according to the method claimed. This method consists in applying the following heat treatments to the alloy:
 - an optional heat-soaking during the manufacturing range (in the case of the welded alloys) or before dissolving (in the case of the moulded alloys) at a temperature of between 490 and 250 DEG C for 1 to 48 h,
 - a dissolution between 460 DEG C and TM( DEG C) = 474 + 18.2%Li 2%Cu (%CU-1.7) + %Mg (-17.6+3.6%Li+4.3%Cu) - 3%Zn. 
<??>The recrystallised products thus treated are insensitive to stress corrosion in the transverse-long direction in the case of flat products and exhibit good fatigue resistance. 
<??>These products are essentially intended for the aeronautics and space industries.

Abstract: A controlled impedance connector assembly includes a receptacle adapted for mounting on a printed circuit board (PCB) and for mating reception of a plug which carries terminal contacts of a plurality of coaxial cable leads. A honeycomb grounding block is mounted in the plug to engageably receive the outer conductor of each coaxial terminal, the inner conductive sleeve of each coaxial terminal being electrically coupled to a signal lead by a first contact member. Signal pin contacts within the receptacle and electrically coupled with the PCB are electrically coupled with each inner conductive sleeve when the plug is inserted into the receptacle. Likewise, ground pin contacts within the receptacle and electrically coupled with the PCB have second and third spaced resilient contact members, respectively, engaging the grounding block at distances farther from and nearer to the PCB than the first contact members. Within each coaxial terminal, air is a primary dielectric between the outer diameter of the signal lead and the inner diameter of the ground lead and the distance between the two is controlled to thereby maintain a substantially uniform impendance in the region of the connector matched to that of the coaxial lead. The signal   and ground pin contacts may be pre-assembled in a holding block for shipping enabling ready assembly into the receptacle and, thereafter, connection to the PCB at the time the connector assembly is being installed. The plug is of a sturdy clam shell design, and reusable zipper-type tubing is used as a jacket to protectively enclose the coaxial cable leads in a bundle as they extend away from the plug.

Abstract: During horizontal storage, the paper rolls (2) are supported along an outer-surface segment by a bearing face (10), the surface of which is matched to the peripheral surface (27). However, particularly in the case of softly wound paper rolls and long storage time, peripheral flattenings may result which, given the high speeds of rotation to which paper rolls are subjected during processing in the printing industry, may have a damaging effect on the work routine. In order to avoid permanent peripheral flattenings, the paper rolls (2) are in each case rotated by a specified angle of rotation after a specified storage time by a transport trolley (5) having two motor-driven rotatable support shafts (23), after which they are stored again in a different position of rotation.
