Title: Flow governor
Inventor: HAINZ NOLTE
IPC: G05D7/01
Filed: 1991-09-28
Granted: 1996-03-15
Abstract: A flow controller (1) possesses, inside a housing (2), a regulating core (3) provided on the outside with control grooves (9), around which core is arranged, at a distance, an elastomeric control element (4) designed as an annular body. This control element (4) is supported in the flow direction on an annular shoulder (5). The control element (4) contracts approximately radially inwards as a function of the pressure prevailing on the inflow side and on the outflow side or of the pressure difference resulting therefrom, and thus influences the passage cross-section bounded by the inside of the control element (4). The control element (4) possesses, in the passage gap (11), a comparatively long annular flat face (6) which is adjoined by a conical inlet portion (7) in the inflow direction. The control element (4) protrudes inwards with its radially inner bearing face beyond the annular-shoulder inner edge (8) facing it. <IMAGE>

Abstract: Such playback devices, e.g. CD players, are fitted with a loading and release mechanism for the recording substrate, the CD. However, before a CD is released from the CD player after playback or the pressing of a 'STOP' button, it must be stopped to prevent damage to its sensitive surface. Because the mass and diameter of CDs varies and there are also mini-CDs, the CD may still be rotating during the release process. To prevent damage during the release process, the CD is safely and rapidly brought to a standstill by generating the necessary braking force dependently upon the rotation speed of the CD. CD players, video disc players, magneto-optical devices, DRAW disc players.

Date Sep. 16, 1993.Method for the manufacture of a photoelectrochemical cell and a cell made by this method. A disadvantage of such cells (1) is the fact that their efficiency is not sufficient for economic use. It is therefore the aim of the invention to avoid this disadvantage. The method according to the invention makes it possible to produce a photoelectrochemical cell (1) comprising a porous electrode (4), the effective surface of which is by a factor 700 greater than that of electrodes of comparable size.
Patent RO-120967-B1 (RO)
Title: Package of flexible articles and process for making the same
Inventor: TIPPEY DAROLD DEAN
IPC: B65D85/07
Filed: 1999-12-14
Abstract: The invention relates to a package of flexible articles and to a process for making the same. According to the invention, the package of flexible articles comprises a row (3) of flexible absorbent articles (5) having a front face (7), a rear face (9), a top face (6), a bottom face (8), some side faces (10), an upper section (11) and a lower section (13), said sections having different gauges, where the package (1) has a flexible outer casing (19), the row having a first region (15) and a second region (17), and the upper section (11) and lower section (13) of the flexible articles (3) being distributed over the first and second regions (15 and 17) of the row, where the distribution of the upper section (11) and lower section (13) is made so that the difference between the size of the first and second regions (15 and 17) of the row is at least 10% smaller than in case that all upper sections (11) of the above mentioned articles are placed in the same region of the row, the claimed package being characterized in that at least one part of the articles is placed with the front faces (7) in a contact relationship, and with at least one part of the rear surfaces (9) in a contact relationship. The process for making the claimed package comprises: conveying the articles, in a certain order, to a folding unit, folding the articles, changing the articles' orientation at regular space intervals, aligning the articles to obtain a row of uncompressed articles, compressing the row and accomodating the same into a flexible outer casing, the process being characterized in that the articles are aligned so that a predetermined number of articles have the front faces or the rear faces in a contact relationship.
