Title: Process and device for the synchronous addition of odours to visual and/or acoustic stimulation
Inventor: WITTEK GOTZ-ULRICH
IPC: A63J5/00
Filed: 1994-04-26
Granted: 2007-07-24
Abstract: In a process for increasing the sensual perception of visual and/or acoustic stimulations, especially in cinemas, theatres, concert and lecture halls and in slide shows, videos, television transmissions, audio games and the like, the viewers or listeners are offered suitable odours synchronously with the provision of certain visual and/or acoustic stimulation. The odours 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 odour-specific temperature which ensures that the odorous or aromatic substances are appreciated.

Abstract: A sieve (38) for sorting fibre suspensions is symmetrical in relation to an axis (34), has an inflow side (306) for the fibre suspension to be sorted and an opposite outflow side (308). This sieve (38) is useful for pressure sorting machines having a rotor (36) that may be rotated around the axis of the sieve and that is provided with profiled elements around the inflow side of the sieve in order to generate positive and negative pressure pulses in the fibre suspension that is to be 406 sorted. The inflow side (306) of the sieve has grooves (400) approximately parallel to the axis of the sieve that follow each other in the circumferential direction of the sieve. A through-channel (406) opens into each groove (400). The grooves (400) are delimited by a front and a rear side wall (400a, 400b), seen in the direction of rotation of the profiled elements. In order to increase the capacity of the pressure sorting machine, the grooves (400) have an approximately V-shaped cross-section, in a section perpendicular to the axis of the sieve, and the front sidewall (400a) of the groove forms an angle from approximately 40.degree. to approximately 70.degree. with the circumference of the sieve.

Title: Video monitoring system for a movie film camera
Inventor: NEIL IAIN A
IPC: H04N5/225
Filed: 1998-06-10
Granted: 2004-02-24
Abstract: A video monitoring system for a movie film camera usable with either spherical or anamorphic lenses wherein conventional, unmodified video monitors and recorders may be used. A video camera is positioned in the film camera to receive an image directly from the camera lens without interposing either a ground glass for imaging or an optical deanamorphosing lens. The anamorphic image, which is horizontally squeezed (such as by a factor of 2), that is received by the video camera then is electronically processed to deanamorphose the image by producing an analog video signal to a video monitor that displays the properly proportioned image in the middle one-half of the monitor screen and produces black areas or strips across the top one quarter and bottom one quarter of the screen. The horizontal lines of the video picture are electronically interpolated for enhancing the picture.
