Abstract: In a process for increasing the sensual perception of visual and/or acoustic stimulation in cinemas, theaters, concert and lecture halls and in slide shows, videos, television transmissions, audio games and the like, the viewers or listeners are offered suitable odors synchronously with the provision of certain visual and/or acoustic stimulation. The odors passed to the viewers or listeners by a stream of vehicle gas are heated before the discharge of the vehicle gas in the air surrounding the viewers or listeners to an odor-specific temperature which ensures that the odors or aromatic are appreciated.

Abstract: The invention relates to a device for supplying substances to be dispensed into air or air mixtures, especially scents, with a flat disk-shaped or plate-shaped base body with multiple separate channels running through it essentially parallel to its top and/or bottom sides, with the channels accommodating the substances to be dispensed and containing an inlet port and an outlet port, respectively, so that a stream of gas supplied to the inlet port can flow through it, with the inlet and outlet ports of at least one channel being sealed in a gastight manner until the substance is released and/or the substance is placed with an airtight seal in at least one channel in a reservoir which does not release this is substance until the time of dispensation thereof.

Abstract: The invention relates to a process for intensifying sensorial perception of an audience in attendance of a visual and/or acoustic representation by introducing scents in synchronism with the visual and/or acoustic representations. The scents are supplied to or removed from the audience area either in groups or separately.

Abstract: A writing implement of the type that incorporates a writing element which has the characteristic of deteriorating in the presence of air is disclosed. It comprises a housing and a writing element contained in the housing. A bias member for urging the writing element into a retracted position and a sealing closure member which is configured to be closed by the housing in the retracted position are provided. A stud is associated with the writing element. A mating stud is associated with the housing and adapted to frictionally engage the stud. The coefficient of friction between the stud and the mating stud is insufficient to overcome the urging of the bias member and prevent movement between the studs, whereby the writing element is driven to the retracted position.

Abstract: The writing implement comprises a sleeve-shaped housing (1) in which an inner sleeve (7) is disposed includes a writing element (2). At the tip-side end of the inner sleeve (7) is disposed a hermetic closure portion (8) which comprises a plurality of segments (34) which are biassed radially outwardly and which in the closure position (FIG. 7 ), bear on each other forming a seal beyond the nib (26) and which are provided with sealing bead segments (23) which also bear on each other forming a seal behind the tip of the writing element (26) and which bear on the tip segment (4) of the writing element (2), so that the nib portion (26) of the writing element is closed in an overall hermetically sealing chamber (6). The writing implement uses a mechanism which facilitates, while pressing the actuating element (11), the premature opening of the closure element (8) before the exit of the writing element (2) therefore avoiding contact with the nib (26 ).
