Title: Yarn feed device for false twister - has endless belt with transversely ribbed surface pressing yarn against driven feed roll
Inventor: DUPEUBLE JEAN-CLAUDE
IPC: D02G1/02
Filed: 1975-12-18
Abstract: A feed device for feeding several yarns to e.g. a false twist texturing device includes a driven feed roll and a pivotal support carrying pairs of a support rolls. An endless belt runs around each pair of support rolls and presses a yarn against the driven feed roll so that the yarn is positively advanced. The outer surface of the belt has transverse ribs. The pressure with which the belt presses the yarn against the driven feed roll is reduced, thereby reducing the power requirements of the feed device.

Title: Pouring top for bottle - has hollow cap pressed against spigot including sealing members with ball between them
IPC: B65D49/04
Filed: 1976-01-06
Abstract: The pouring stopper has a spigot (1) forming part of the stopper proper, fitting inside the spout of the bottle etc (2). A hollow cap (8) with an opening at the top has internal axial teeth (10) which can be held pressed against a collar (3) formed at the upper end of the spigot. The spigot, together with the cap, is held on the spout by means of a sleeve (11) on the outside of the latter.

These form a chamber for a ball (5). When the vessel is placed on a horizontal surface, the sealing members bearing against top and bottom seats in the spigot, but on inversion the lower one moves under gravity towards the end of the spout and the ball pushes the upper one in the same direction.

Title: IC engine fuel economiser - has needle and solenoid valves in fuel lines with excess return to carburettor
IPC: F02M37/00
Filed: 1976-01-30
Abstract: The fuel economiser for a vehicle engine has two feed lines to the carburettor. In one, is a needle valve, and in the other lines is a solenoid valve. The needle valve (2) controls the minimum fuel supply necessary for normal engine operation, the excess, froma fuel pump (4) being returned to a tank (5). Under changes in engine operation, the solenoid valve (1) opens to fill the carburettor bowl. If the solenoid valve fails, the needle valve may be opened to a maximum to return the capacity of the circuit to its original level. In this case, there is no fuel return to the reservoir, the resistance of the return circuit being greater than that of the direct feed circuit.

Title: Removing aromatic cpds. from paraffins by sulphonation - using sulphur trioxide in series of reactors with intermediate separation
IPC: C07C7/17
Filed: 1976-07-09
Abstract: Removal of aromatic cpds. and other unsaturated cpds. such as olefines from mixts. of paraffin hydrocarbons, comprises treating the material with SO3 in a series of >=2 reactors and between each reactor the sulphonated cpds. are sepd. before the mixt. passes to the next reactor. An appts. for carrying out the above process comprises at least two cascade reactors and, between each, a separator for sepg. the sulphonated products by means of their greater density and viscosity; also means for feeding the reactors with the gaseous SO3 contg. reactant and means for removing unreacted gas from each of the reactors. The process is used to purify paraffin fractions, esp. when they are required for a subsequent sepn. stage in which the n-paraffins are sepd. from the isoparaffins. In previous processes of this type, oversulphonation can take place together with formation of SO2. By using decreasing and insufficient amts. of SO3 at each stage, oversulphonation is avoided and a product contg. below 20 ppm of aromatic cpds. is obtd.

Title: Insulating sheet with closed air cells - has two composite polyolefin-polyamide sheets with the facing polyolefin layers united
Inventor: HERWEGH KARL JULIUS
IPC: B32B3/28
Filed: 1977-08-31
Abstract: One of the composite polyolefin/polyamide sheets is flat and the other composite sheet is corrugated. The polyolefin is pref. polyethylene and the polyamide is pref. Nylon. To avoid possible thermal rupture of the sheets during welding to form the closed cells, e.g. consequently reducing the thermal insulating properties of the united composite sheets due to lack of sealing of the air cells, or to avoid weakening of the cell structure, the polyamide layers of the composite sheet are ketp remote from each other during welding and the polyolefin layers are united at the base of the corrugations. Only the polyolefin layer is softened during welding, whilst the flexible polyamide layer maintains the continuity of the composite sheets and preserves the cell structure. The exposed peaks of the corrugated sheet are pref. covered with a plastics layer. The composite sheets are used for thermally insulating packaging materials and pref. have an adhesive coating to prevent the packaged goods slipping w.r.t. the packaging.
