Abstract:
A filing binder comprises a plurality of elongated binding members made of a resilient material. Each of the binding members has a groove extending along the length of the binding member and formed with a slit opening opened at one side of the binding member. The groove is of a cross-sectional configuration which is enlarged from the slit opening toward transverse inward direction. The binding members are arranged in side-by-side relationship with the slit openings directed to the same orientation and connected together by flexible or hinge connection.
Abstract:
An apparatus for simultaneously inserting a plurality of slides into a file sheet and a method for using such apparatus is disclosed. The apparatus comprises a series of pockets which align with a series of compartments in a slide structure. Pawl members in the compartments engage with the slides to retain the slides in the pockets. The slide structure moves reciprocally longitudinally, as well as vertically in the plane of the mounting plate.
Abstract:
The present invention includes an apparatus for displaying a model of a flying object in a flying condition. By the propulsion of powerless models of flying objects through a circular path under an external power source, the aerodynamic characteristics of the model of the flying object cause the model to be lifted into a flying condition. The apparatus is useful for observing the flight stability of a model of a flying object and as a promotional display for models of flying objects. A driving device is used to rotate the model through a flight path. A transparent hanging line connects the model to the propulsion device.
Abstract:
A film jacket comprising a base sheet, one or more transparent surface sheets, each having three edges thereof fixed to the base sheet so as to form pockets, and cover members fixed to the base sheet for covering extended portions of films outside the pockets, whereby firmly holding films at desired positions.
Abstract:
An overhead projector comprises a stage having at least two guide members fixed to its upper surface and movable longitudinally and transversely above a projector body, a file page having a plurality of slide films fitted therein in rows and columns and pairs of reference edges spaced apart at equidistances from crosswise and lengthwise center axes of the file page and adapted to abut against the guide members of the stage for positioning the file page relative to the stage, and positioning means for determining movements of the stage at determined intervals. The slide films in the file page are spaced apart at distances correspondingly equal to the movement distances determined by the positioning means. The projector is capable of correctly positioning a file page relative to the stage with ease after the file page has been rotated or turned upside down for changing over the projection methods of the projector, such as reflection projection and transmission projection.
Abstract:
A file sheet storing device comprising a first sheet made of a transparent material and adapted to cover one side surface of a file sheet, a second sheet made of a transparent or an opaque material and adapted to cover the other side surface of the file sheet. The first and the second sheets are connected together to form a bag-shaped cover along three edge portions leaving the remaining edge portion at least partially unconnected to provide an opening for insertion of a file sheet. The bag-shaped cover is formed along one of the three edge portions with a bonded portion for binding the cover to a book-shaped binder. The cover is further formed along the edge portion where the bonded portion is provided with a line of attachment between the first and the second sheets for preventing the file sheet from being displaced toward the edge portion where the bonded portion is formed.
