Abstract: During the production of rim holes in sheet metal parts by stepwise deformation by means of deformation tools, the wall thickness of the rim hole decreases relative to the starting material. This is particularly true in the case of relatively large rim-hole depths and relatively large-area sheet metal blanks. The invention now indicates a method by which deep rim holes for highly stressed screwed connections can be produced with a wall thickness similar to the thickness of the starting material from large-area sheet metal blanks. In the method according to the invention, wide-area pressure on the sheet metal part is exerted only after partial pressing in has already begun. This means that the edge zone is no longer, as hitherto, first of all fixed and held smooth during deformation but is involved in the deformation process and is smoothed out again subsequently. The invention is of particular importance for metal fabrication, namely motor-vehicle and implement construction. <IMAGE>

Abstract: A liquid-containing paperboard laminate carton including a one-piece plastic spout (1) having a pair of opposing flanges (4,6) sealed about an aperture (5) in one of the carton walls to both the innermost (26) and outermost (2a) surfaces of the carton wall. The double flange configuration not only forms a mechanically positive innerlock between the plastic spout and the carton wall, but even more importantly, isolates the cut edges of the aperture from exposure to liquid either from within the container or from the environment through which the carton must pass from the point of manufacture until it is ready for disposal after its contents have been consumed. The spout preferably includes a liquid passageway having a membrane-type seal (1c) across its discharge orifice to provide evidence of tampering and a resealable closure member (1b) such as a screw cap or a snap-on closure held in place by means of a mating ring or groove on the spout. The cross-sectional area and configuration of the liquid passageway and discharge orifice in the spout are designed to prevent to complete blockage by liquid when the package contents are being dispensed during a normal dispensing cycle, i.e., when the package is not being held completely upside down. Method and apparatus for securing said one-piece spout in sealed liquid type relation of both surfaces of the carton wall either sequentially or simultaneously are also disclosed.

Abstract: When rolling out a series of billets one billet (2B) at a time is ejected out of a billet furnace (1) towards a conveyor apparatus (6) which conveys the billet (2B) on towards a first mill stand (4) of a rolling mill train. To improve the throughput of billets, a sensor (3) is provided between the first mill stand (4) and the conveyor apparatus (6) close to the latter. The conveyor apparatus (6) initially has a conveying speed matched to the ejection speed of the billet (2B). The billet (2B) is conveyed at this speed until it is detected by the sensor (3), whereupon the conveying speed of the conveyor apparatus (6) is increased in dependence on signals provided by the sensor (3), and then finally is adjusted to a value which corresponds to the conveying speed of the rolls of the first mill stand (4).

Abstract: A process is provided for the production of a monohydroxy monocyclic acetal, e.g., trimethylolpropane cyclic formal, of a trihydroxy alcohol, e.g., trimethylolpropane, and an aldehyde, e.g., formaldehyde, by subjecting a"heavier condensation product" of the trihydroxy alcohol and the aldehyde than the desired cyclic acetal, i.e., one having a higher molecular weight and boiling point, to acetal formation conditions. In a preferred embodiment, the product of reaction of the trihydroxy alcohol and aldehyde is treated to remove the desired monohydroxy monocyclic acetal product and at least part of the remainder comprising the heavier condensation product is recycled to the reaction together with a fresh supply of trihydroxy alcohol and aldehyde. The monohydroxy monocyclic acetal product may be further reacted to obtain a desired ester, e.g. trimethylolpropane cyclic formal acrylate, such as by transesterifying the acetal with a low boiling ester of the esterifying acid, e.g., methyl acrylate, using tetra-isopropyl orthotitanate as transesterification catalyst.

Abstract: A removable package for dispensing syrup in a post mix soft drink dispensing system and an actuable closure mechanism therefor. The package comprises an upper body portion 18 from which a lower discharge portion extends outwardly therefrom and which includes a generally horizontal discharge port. The closure assembly 36 is comprised of a movable outer cap member 40 pivotally attached to a facing member 38. The facing member fits over the discharge port and includes a syrup outlet opening 46 and an air inlet opening 44 therein. The cap member includes means for closing off both openings when in contact with the facing member. An actuator including a spring biased roller 60 contacts the cap member such that when a dispensing operation is required, the cap member is swung outwardly by means of the roller away from the facing member, exposing the syrup outlet and air inlet openings. When the dispensing operation is completed, the roller urges the cap member back into contact with the facing member to reseal the openings therein.

Abstract: The ultraviolet photodiode comprises a combination of two photodiodes which are electrically connected to each other in such a way that when the two photodiodes are exposed, a signal is produced which is proportional to the difference in the two diode currents. The maxima in the spectral sensitivity curves (1, 2) of the two photodiodes are at different wavelengths. In the visible and infrared wavelength regions, the spectral sensitivity curves (1, 2) of the two photodiodes have approximately equal values, so that as a result of subtraction, the diode currents of the two photodiodes approximately compensate for one another in this region. One of the two photodiodes is more sensitive in the ultraviolet wavelength range than the second photodiode, so that the sensitivity curve (3) of the ultraviolet photodiode has a narrow maximum in the ultraviolet wavelength range. The ultraviolet photodiode is advantageously used for flame monitoring in combustion plants.

Abstract: The present invention is a concentration swing adsorption process for separating a liquid phase feedstock comprising a more adsorbable component (A) and a less adsorbable component (B) with respect to an adsorbent. The process is operated in a system comprising a single or a plurality of adsorption columns containing the adsorbent which are operated in cycle in a predetermined sequence. The following operational steps are performed in the order recited in each of the adsorption columns in its turn. Feedstock is passed through the adsorbent and the more adsorbable component (A) is selectively adsorbed while a stream enriched in component (B) is discharged from the adsorption column. The adsorbent is rinsed in a direction co-current to the feedstock with the more adsorbable component (A) whereby the less adsorbable component (B) is displaced from the adsorbent and a stream comprising a mixture of the more adsorbable component (A) and the less adsorbable component (B) is withdrawn from the adsorption column. The adsorbent is rinsed with a liquid desorbent (D) whereby the more adsorbable component (A) and the less adsorbable component (B) are displaced from the adsorbent and a stream comprising the more adsorbable component (A) is withdrawn from the adsorbent bed. Mixtures containing the desorbent (D) and either component (A) or component (B) are easily separable by simple distillation and the separated desorbent (D) is recycled. The invention provides an energy efficient process for separating mixtures containing an azeotrope, close-boiling components or temperature-sensitive components which are very difficult to separate using conventional techniques.
