A top down/bottom up covering for an architectural opening is disclosed in a roll-up configuration so the shade can be rolled about a roller in a head rail while having the ability to raise and lower top and bottom rails between which the shade material extends independently of each other. The roller is utilized to raise and lower the bottom rail by wrapping about or unwrapping the shade material from the roller and a control system for raising and lowering the top rail is confined within the roller. The invention is disclosed in embodiments that include a single operating element or a pair of operating elements but in each instance the top and bottom rails are independently movable so the shade material can be extended to any degree between the top and bottom rails and positioned at desired locations within the architectural opening in which the covering is mounted.

The present invention incorporates ways to rapidly open an envelope in which an adhesive bandage is packaged in a sterile manner. Such bandages are commonly described as Band Aids™. The method consists of a modification of the tabs currently used on one end of nearly all such envelopes. The modification consists of the enlargement of the tabs and the use of an additional fold to make the tabs easily gripped because they project out from the envelope. An additional embodiment of the invention causes all the envelopes in a box to be anchored in the box by tabs which are extensions of one half of each envelope, so that by pulling on the tab of the other half of the envelope, the bandage is both pulled from the box and extended from the envelope. An additional enhancement of the invention has one of the release strips protecting the adhesive portions of the bandage to adhere to the envelope, making the bandage ready for application without the need to remove that release strip through a separate action. A variety of bandage sizes may be included in one box, each size being available by a separate opening.

摘要:
A flat plate hydronic solar collector combining features of both the trickle and pressurized type of collector and also of metal and plastic collectors, the invention consisting of a plastic film tube divided into pockets into which heat transfer liquid flows by gravity, moving through a multiple number of pockets as the liquid progresses through the tube, removing heat from the side of the tube facing the sun, the pressure in each pocket being limited by the depth of the pocket. An important embodiment of the invention has a metal solar energy absorber plate secured over the film tube and its mounting surface so that the swelling of the film tube causes it to make extensive contact with the metal absorber.

An improved expandable and contractible window covering comprising a series of elongated cells is disclosed. Each cell is formed by joining a pleated sheet of material with an unpleated sheet in an area of creases on the pleated sheet. The rear wall of the cell is of less height than the front wall of the cell and the material of the cell is chosen to be relatively soft and flexible so that the front wall of each cell droops downwardly and outwardly away from the rear wall. The covering is mountable on a roll bar so as to be retracted by rolling about the roll bar and extended by unrolling from the roll bar.
摘要:
A window shade comprising a base sheet-like material, such as a fabric, (1) which hangs vertically from a roller and to which is attached, by parallel narrow attachment means at intervals, a second sheet-like material of a decorative character (3) which is longer between its attachments (2) to the first material (1). If there is sufficiently excess decorative material (3) between lines of attachment (2), it folds twice between lines of attachment (2) when such a shade is rolled up. When the shade unrolls, the decorative material (3) flexes out from the base material (1) because of its greater length and forms an air-filled cell. Vertically arranged strips of these cells (18) may be formed on a single base sheet, with each strip unique in various ways to obtain a decorative effect. The shades may also be made of strips of material running the width of the shade. Decorative material which does not crease or fold tightly may be attached to the face of flexible material on a cell-by-cell basis. Variations in the dimensions of groups of cells can cause them to create decorative patterns of different types when they are viewed collectively.
摘要:
A jet pump in combination with a fluidic device or system, the jet pump receiving a small volume of high pressure fluid and supplying a larger volume at lower pressure to the fluidic device or system, utilizing the fluid at a maximum pressure of 2 p.s.i., the pump entraining fluid from an auxiliary source to provide the increased volume. Fluid under high pressure is passed through a nozzle into an expansion chamber connected to an auxiliary fluid source. The high velocity fluid stream emanating from the nozzle draws fluid from the auxiliary source and passes through a collector to an output. A feedback may be bled off the output to operate restriction means varying the fluid available from the ambient source, or the high pressure source.
