Title: Lamp socket fixture in automobile lamp - using folded elastic portions of rigid components with hooks released by hand pressure
IPC: F21V19/00
Filed: 1974-07-23
Abstract: The process is particularly for securing sockets in the lights of motor vehicles, and uses folded elastic portions (24) of rigid components (21) and incorporating hooks (24.1) securing the mounting (9) of the socket in position. The hooks are released by pressing the rear ends of the components inwards (27), this inwards movement being limited by stops (28), using hand pressure. The hooks also seal the assembly completely.

Title: Trailer with skip for grape harvesting - has skip movable vertically on intermediate frame pivotal behind and above axle
IPC: A01D90/12
Filed: 1974-12-24
Abstract: A grape harvesting trailer with a movable skip has a main chassis carrying a single axle and an intermediate frame which supports the skip. The chassis is formed of longitudinal and transverse members and extends upwards at the rear. The intermediate frame can be moved along the inclined rear part of the main chassis using rollers running in tracks on the chassis members. A ram initially raises the intermediate frame parallel to a ramp, and when the rollers engage stops on the tracks further extension of the ram pivots the frame and skip about the roller axes which are above and behind the axis of the axle. The skip runs along the frame due to gravity until it engages stops, the resulting shock causing emptying of the skip behind the trailer.

Title: Automatic weighing and sack filling of potatoes etc. - via single layer conveyor to increase output within wt. tolerance
IPC: G01G13/08
Filed: 1975-08-08
Abstract: The installation is of the type comprising an inclined conveyor made up of two bands of different widths, running alongside each other from a feed hopper at the bottom to deliver into an automatic weigher at the top. The wider, fast fill, band is stopped as the batch wt. is approached and the narrower, fine fill, band brings the batch up to wt. The weigher delivers batches into sacks which are then sealed. The conveyor is designed to elevate a single layer only of bulk prod. Pref. each band has transverse flights of height sufficient to prevent only a single layer from rolling back into the hopper. Each band pref. runs between close side walls of flight height so that the width of band load is defined. Each band is pref. vibrated to ensure that surplus prod. rolls back into the hopper. Used for filling sacks etc. with weighed batches of potatoes, other vegetables, fruit or similar bulk prod. There is improved weight control of sacked batches.

Title: Jet engine thrust increasing device - has supplementary nozzle which surrounds split coned end of engine jet pipe
IPC: F02K1/36
Filed: 1976-10-21
Abstract: The jet pipe (2) of an aircraft jet engine has a convergent extension (9) with a half angle of about 9 deg. The walls of the extension have four equally spaced longitudinal slots (12).

Title: Sheath-core yarn having latent elasticity - produced by feeding a carded sliver to a textured continuous filament in a spinning head
IPC: D02G3/32
Filed: 1976-10-21
Abstract: A textured continuous filament is introduced into a spinning head with a carded sliver. The textured yarn is fed in under tension, whilst the carded sliver is fed more slowly so that the yarn provides a support which is clothed by the carded sliver. The prod. as taken from the machine, provides the aspect of a conventional spun yarn, but the elasticity is only obtd. when the yarn, or fabric, is submitted to washing, steaming or finishing. The prod. can be used in knitted goods, in clothing fabrics or furnishings, used either as warp or weft yarns. It offers a bulky, supple fabric having crease resistance and elasticity.
