Title: An intelligent sofa
Inventor: XIANFENG WU
IPC: A47C17/00
Filed: 2019-10-18
Abstract: This invention discloses an intelligent sofa, wherein a back cushion is angularly connected with a pedestal via an expansion link, and enabled to rotate along the pedestal by expansion and retraction of the expansion link; an extension pad provided with an actuator is connected with one end of the pedestal, a drive assembly drives the extension pad to extend according to an instruction of a controller, such that a surface of the back cushion, a surface of the extension pad and a surface of the pedestal are is located on a same level. The extension pad is provided with a first distance sensor for detecting a distance between the extension pad and an obstacle, and the back cushion is provided with a second distance sensor for detecting a distance between the back cushion and an obstacle. The controller performs the operation of extending the intelligent sofa depending on a determination that the distance value detected by the first distance sensor and the second distance sensor satisfies the requirement, otherwise an alert would be issued to remind the user of clearing up the obstacle. The intelligent sofa provided according to this invention can detect a distance between the sofa body and the obstacle by itself, and can perform transforming operations by itself without further need of manual adjustment operation by the user, thereby simplifying operations and improving experience.

IPC: B29C65/20
Filed: 1966-05-27
Abstract: 1,154,575. Sheet forming; seaming non- metallic sheet material. FARBWEBKE HOECHST A.G. 30 June, 1966 [30 June, 1965], No. 29497/66. Headings B5A and B5K. A pipe fitting is made by sheet forming each half of the fitting between a mould and an associated core, exposing the rim of each half whilst it is retained within its mould, heating the exposed rims and finally moving the moulds together to weld the two halves into an integral fitting. In the embodiment shown in Fig. 1, halves 5, 6 of a branched pipe fitting are formed between mould halves 1 and 2 and cores 3 and 4 respectively. The top layer of a facing 8 is then removed from each mould half to expose the rim of each half 5 and 6, a heating plate inserted between the mould halves, and mould halves forwarded together to press the rims against the plate. The mould halves are subsequently retracted, the heating plate removed, the lower layer of each facing removed, and the mould halves re-forwarded to press the rims together and complete the formation of the pipe fitting. In a second embodiment, see Figs. 5 and 6 (not shown), a single sheet is bent around a core and the core enclosed by two mould halves to preliminarily form the fitting. Facing layers are then removed from the middle of the core and the mould halves and a heating plate substituted against which the rims of the fitting are pressed, said plate subsequently being removed and the mould halves moved together again to form the complete article as before. In this case the welded seam only extends partway round the fitting. In a third embodiment (see Figs. 7 and 8, not shown) the mould halves and the core are foldable about a hinge from a flattened position to a position in which the mould halves surround the core.

Filed: 1975-02-04
Abstract: High octane gasoline is produced by contacting a feedstock comprising (a) >=lower aliphatic organic cpd. contg. =8 C atoms in its longest hydrocarbon chain, and >=1 heteroatom collected from N, O, S and halogen, and (b) a hydrocarbon fraction with a RON (clear) of 85, at 205-540 degrees C with an aluminosilicate zeolite catalyst with a SiO2=AlO3 rtio of 12=1, a "restriction index" of 1-12 and a crystal density of 1.6 g/cm3; and isolating a roduct boiling in the gasoline range with a RON higher than that of the hydrocarbon part of the feedstock, the product contg. a major part of the carbon content of the feedstock. The use of a mixed feedstock has a synergistic effect on the gasoline yield, i.e. the yield from each component is higher than if components (a) and (b) are converted separately, and improves the volatility characteristics of the gasoline prodt. The RON is higher than if either component is converted on its own and then mixed with the other component.
