Title: Cleaning apparatus for exterior of elongated members
IPC: B08B9/02
Filed: 1988-03-17
Granted: 1991-02-27
Abstract: A cleaning apparatus (10) for elongated articles such as lengths of tubing or bar stock (12) has a cleaning housing (16) through which an article (12) is passed axially for cleaning. Inside the housing (16) is an array of helically disposed brushes (30) which wipe the outer surface of the article (12) as it is passed between them. Cleaning solvent is circulated through the housing (16). The brushes (30) are circumferentially disposed and helically oriented to define a central tunnel through which the article is passed and the diameter is such that the brushes (30) wipe the outer surface of the articles (12). The helical disposition of the brushes (30) insures that the entire outer surface is wiped. The housing (16) has adjustable end plate assemblies (24, 26) allowing the position of the brushes (30) to be varied so that different diameter articles (12) can be accommodated. The apparatus (10) also includes a resilient wiper ring (68) at the outlet of the housing (16) through which the elongated articles (12) pass for the removal of moisture from their surfaces.

Title: Editing control system for recording and/or reproducing apparatus for video tape and so forth with high efficiency preview operation
IPC: G11B27/024
Filed: 1988-03-21
Granted: 1991-01-09
Abstract: An editing system measures the servo-lock period in every pre-view operation. Pre-roll time is updated based on the measured servo-lock period. Magnitude of rewinding of the tape is thus adjusted on the basis of the updated pre-roll time. By up-dating the pre-roll time in accordance with servo-lock period measured in actual operation, the pre-roll time can be set at a minimum value to be determined according to the servo-lock period. Therefore, the tape does not over shoot the optimum queing position and the period preceding the cut-in point during pre-view operation can be kept short.

Granted: 1991-02-20
Abstract: Un inconvénient des dispositifs pour commander le ralenti dans des moteurs à combustion interne réside dans le fait que, lorsque le moteur de réglage est excité et que le ressort ne fonctionne pas, le dispositif est complètement ouvert et par suite, le moteur à combustion interne reçoit une quantité dangereuse de carburant. Le dispositif décrit est conçu de manière à ouvrir, en position de sortie, une section auxiliaire qui correspond au point (A) de la courbe et grâce à laquelle peut s'écouler une quantité auxiliaire de carburant par unité de temps. Lorsqu'un moteur de réglage du dispositif eet excité, un organe d'étranglement est tout d'abord déplacé, à l'encontre de la force d'un ressort, dans une position (s1) correspondant au point (B) de la courbe et dans laquelle peut s'écouler, grâce à une ouverture de commande, la plus grande quantité possible de carburant par unité de temps. Ensuite, la quantité de carburant par unité de temps est réglée au moyen de l'organe d'étranglement jusqu'à la position (s2) dans laquelle l'organe d'étranglement ferme l'ouverture de commande. En cas de rupture du ressort tandis que le moteur de réglage est excité, l'organe d'étranglement est alors réglé sur la position (s4) correspondant au point (E) de la courbe et dans laquelle s'ouvre une section de sécurité par l'intermédiaire de laquelle peut s'écouler une quantité de carburant par unité de temps inférieure à celle qui s'écoule par l'intermédiaire de l'ouverture de commande complètement ouverte. Le dispositif est utilisé pour régler le ralenti dans des moteurs à combustion interne.

Abstract: A method is described for driving a throttle element arranged in the intake system of an air-compressing injection internal combustion engine, which element in the low load and speed ranges is held in the closed position and in the middle and high load and speed ranges is held in an opening position. 
<??>In order to be able to achieve a reduction in the emission of pollutants, particularly particle and nitrogen oxide emissions without the use of a costly device for the recirculation of exhaust gas, it is proposed to adjust the throttle element at any operating point of the internal combustion engine to that opening position which corresponds to an absolute pressure in the intake system downstream from the throttle element, which is determined from a load and speed-related characteristic, the reference value for the absolute pressure being corrected as a function of other operating parameters of the internal combustion engine.

Abstract: An alkane, e.g. propane, is converted to an alkene in a catalytic dehydrogenator. The resulting stream is introduced into an ammoxidation or oxidation reactor. The product formed therein is recovered in a conventional quench tower. The pressure of the gaseous effluent from the quench tower is raised and it is introduced into an absorber/stripper unit employing a liquid hydrocarbon to form a recycle stream containing unreacted alkane and alkene as well as a minor amount of oxygen, typically 1% percent by volume, and a waste stream comprising the remainder of the quench tower gaseous phase. The recycle stream is introduced into a selective oxidation unit to remover the oxygen therefrom and then recycled to the dehydrogenator. Flammability of the waste stream from the absorber/stripper is minimised by appropriately selecting the operating parameters of the process, and if necessary, by the addition thereto of a gaseous flame suppressor. The gaseous flame suppressor is removed with the absorber/stripper unit waste stream which may advantageously be combusted to provide energy for the process. A PSA unit may be utilised to remove excess hydrogen from the dehydrogenator effluent. The dehydrogenator may be a multistage dehydrogenator making it possible to do without the selective oxidation unit.
