Title: Film cassette
Inventor: ROBERTSON JEFFREY C
IPC: G03B17/26
Filed: 1989-05-11
Granted: 1992-03-31
Abstract: Abstract Film Cassette A film cassette (1) is disclosed wherein a spool (5) is rotatable within the cassette shell (3), a convoluted film roll (37) is wound on the spool, and a pair of flanges (51 & 53) are rotatable with the spool.  The flanges (51 & 53) have respective disks (55 & 57) overlying opposite sides (63 & 65) of the film roll (37) and respective annular lips (59 & 61) circumferentially extending from the disks to radially confine an outermost convolution (47) of the film roll to prevent the outermost convolution from clock-springing against an interior wall (73) of the cassette shell (3). Each of the annular lips (59 & 61) includes an annular constraining section (71) positioned relatively remote from one of the disks (55 & 57) and a predetermined radial distance (R1) from the spool (5) to enable a lip to contact the outermost convolution (47) of the film roll (373 at a limited location remote from a disk, to radially confine the outermost convolution, and it includes an annular relief section (75) extending from the disk to the constraining section (71) and positioned a predetermined radial distance (R2) from the spool, greater than the first-mentioned distance (R1), to enable a lip to avoid contacting the outermost convolution substantially between the disk and the constraining section.  This arrangement provides an essentially radial contact between the annular lips (59 & 61) and the outermost convolution (47), thereby preventing any clock-springing of the film roll (37) from generating an axial force against the flange (51 & 53) of the spool (5).

Abstract: SUSCEPTOR FOR HEATING FOODS IN A MICROWAVE OVEN HAVING METALLIZED LAYER         DEPOSITED ON PAPER                         ABSTRACT       A susceptor for heating a food substance in a microwave oven is disclosed which has a thin film of metal deposited on a dimensionally stable dielectric substrate, such as paper.  Substrates having a rough surface may be used.  Preferably, the susceptor has a complex impedance measured prior to heating, at the frequency of the micro-wave oven, which has a real part between 30 and 2000 ohms per square.  The preferred thickness of the thin metal film is related to the smoothness of the paper substrate. A substrate having a surface smoothness, expressed as an arithmetic average roughness, greater than 0.5 microns may be used with the present invention.  The metal film is preferably aluminum having a thickness between 50 Angstroms and 600 Angstroms.  The substrate may be coated with coatings such as clay.  Clay coated paper substrates having a thin film of metal deposited thereon exhibit improved stability of performance characteristics during microwave heating.

Granted: 1993-01-19
Abstract: ABSTRACT    A safety brake system for a walk behind lawn mower in which provision is made for alternative orientations of the engine relative to the mower deck and operator's position while utilizing the same components for the safety brake system.  Only the interconnection of the components is changed for the alternative engine orientations.  In one configuration, a control lever connected intermediate an operator actuated bowden cable and the brake disengagement device is pivoted between the attachment points of the control lever to the bowden cable and the disengagement device such that a reversal of direction of pull is effected.  In the other configuration, the point of attachment of the control lever to the disengagement device is on the same side of the pivot as the point of attachment to the bowden cable such that no reversal of direction of pull occurs.  The control lever is manufactured with both attachment points so that a bowden cable approaching the engine from the rear of the mower can by attached to one or the other to actuate the brake disengagement device regardless of the selected orientation of the engine.

Abstract: The decoder comprises a microprocessor connected to a receiver of data of teletext and to a text generator for displaying informations on the screen of the television receiver. Further, a card said CPTV-card (card pay-television) is associated to the microprocessor, this card managing the credit necessary for the purchase of emissions, for the memorization of the emissions purchased and for permitting the unscrambling of the emissions purchased by delivering to the microprocessor the input pointer in the sequence which is calculated by the microprocessor by means of the information which has been memorized as well as the information delivered by the decoder. The programs of the forecasted emissions are transmitted by the head station and memorized in the microprocessor of the decoder. Another memory of the microprocessor contains the instructions for the manipulations to be effected for selecting an emission and for purchasing it as well as for recharging a credit in the CPTV-card. A keyboard permits to select and to display on the screen of the television receiver the forecasted emissions as well as the instructions of manipulation which enormously facilitates the dialog between the user and the decoder and contributes to avoid errors of manipulation.  The decoder according to the invention operates as a guide for the user, for all operations to be effected.
