Title: Indoor roller insulating screen - can be operated by hand or electric motor and is attached to cord wire via spring for tensioning
IPC: E06B9/40
Filed: 1983-12-23
Abstract: The sun screen can be used in greenhouses, verandas or conservatories. In additon to preventing sunlight entering the area, it can be used during the winter to limit heat loss. It can be coupled with similar screens and driven by hand or a motor. The rectangular screen frame (1) is at an angle to the horizontal, e.g. under a sloping glass roof and has a shaft (2) which passes through at one end of the frame. - A fabric or plastics sheet (3) is attached at one end to the shaft by means of glue, clamps or screws. When the screen is to be opened, the shaft is rotated and the sheet rolled around it. The other edge of the sheet is attached, via a spring, to a wire or cord (4), which provides tension when the screen is unrolled. The wire loops around guide pulleys (5,12) which carry it away from the centre of the frame and along one edge to be wound around a pulley (9) on the shaft.(1/1)

Abstract: MODE SELECTOR LOCKOUT MECHANISM FOR A             CASSETTE TAPE RECORDER/REPRODUCER                          ABSTRACT     A mode selector mechanism for a magnetic tape recorder/ reproducer device for use with a cassette and having a housing, a cassette receiving opening, a tape drive mechanism and a plurality of actuators including a play, a stop and a record actuator, which actuators are movable from an outward at rest position to an inward operative position.  A locking mechanism is positioned within the magnetic tape device housing and includes a first portion and a second portion, both portions being en-gageable with the actuators.  When the tape transport is inserted into the tape player device, a solenoid is energized to move the first portion from a first position to a second position wherein it is selectively engageable by at least one of the actuators for holding the same in the inward operative position.  The second portion of the locking mechanism is positioned within the housing and is engageable with the play actuator.  Engagement of the play actuator with the second portion slidably moves the latter to prevent the inward movement of the record actuator.  A connector arm is provided within the player and is engageable with either of the play or record actuators to effect engagement of the tape transport with the tape drive mechanism.  The stop actuator is movable to an inward position for engagement with the first portion to disengage the play and record actuators, whichever is in the operative position.

Abstract: MULTI-LAYERED OPTICAL DATA RECORDS AND PLAYBACK APPARATUS             Abstract Multi-layered optical data records and playback apparatus are described in which a plurality of optical data layers are provided on at least one side of a record substrate and the playback apparatus scans data tracks on such layers with a light beam to produce an electrical read-out signal corresponding to the data in the scanned tracks.          The playback apparatus includes selection means for selectively playing back data tracks on different ones of the data layers.  The data track may be formed by lines of data spots of binary coded digital information or such spots may be frequency modulated or pulse length modulated analog information which are photographically recorded at extremely high data density so that they may be used to record audio or video signals including television signals.  While the optical data records may be light transparent, they are preferably light reflective so that the playback light source and associated focusing and scanning means may be supported on the same side of the record as the light detector to provide a more compact playback apparatus.  This also enables at least some of the same optical elements to be used for transmitting the reflected light beam to the detector that are used for transmitting the playback light beam from the light source to the record.  Selection of one data track for playback may be accomplished by changing the focus of the light beam from one data layer to another, or by making the data tracks of optically different materials, such as using different color dyes or different photo-luminescent materials, and selectively positioning corres-ponding color filters in front of the light detectors.

Abstract: COMBINED PRESSURE AND TEMPERATURE CORRECTION APPARATUS FOR  GAS METERS          Abstract of the Disclosure A self-contained unit integrally operable in conjunction with a gas meter registers equivalent standard gas volume by correcting actual gas volume for both pressure and temperature.       A magnetic couple provides a drive input to the correction unit at a rate proportional to the operational rate of the meter.          Separate temperature and pressure sensitive mechanisms exposed to the gas flow each provide a linear displacement proportional to changes in their absolute condition.  Respective displacement of each is supplied independently to a dual input single output multiplying mechanism from which an integrated output serves to position a limiting cam in angular correlation therewith.  Posi-tion of the cam effectively modifies the drive input from the magnetic couple through a crank and clutch arrangement that drives the corrected register at a rate correlated to the inte-grated function of absolute pressure and temperature of the metered gas.

Abstract: TIE ROD END         ABSTRACT OF THE DISCLOSURE           A preloaded tie rod end assembly for a motor vehicle steering system and a method for making the assembly is disclosed.  The tie rod end is made by positioning the ball of a ball stud against a pair of frangible bearings within the socket portion of a tie rod end housing.  A plastically deformable element is also situated within the housing.  A closure member for the housing exerts a force against the bearings during the assembly operation and causes each bearing to fracture into circumferentially spaced bearing pieces.  After the tie rod end is assembled, an axial load is placed upon the ball stud which is trans-ferred to the deformable element thereby causing it to de-form.  The element is deformed to the extent necessary to bring the frictional resistance to rotation of the ball stud about its own axis within a prescribed torque range.
