Title: Coiled seam welded tubing prodn. line - with shear positioned downstream of tube bending rolls
Inventor: SHEVAKIN JURY FEDOROVICH
IPC: B21C37/08
Filed: 1981-10-28
Abstract: Welding line for prodn. of coiled tubing from coiled strip comprises (i) a coil handling station consisting of a reel, which can be moved transversely w.r.t. the line, and a bobbin which carries the strip coils; (ii) a strip butt-joining assembly; (iii) strip shaping, seam welding and advancement stations, (iv) a tube coiling station including bending rolls; (v) a coiled tube receiving station including guide rollers controlled by the same controller as the bending rolls; and (vi) a device for cutting the tubing into lengths, positioned downstream of the bending rolls. The guide rollers are mounted on a platform which can be inclined w.r.t. the axes of the bending rolls and is connected to the output shaft of the controller via a universal joint. The welding line is esp. useful for prodn. of thin-walled tubing (esp. tubing having an o.d. to wall thickness ratio of about 60) at welding speeds of about 15 m/min. The line produces tube coils of the required length independently of the lengths of the strip coils and operates continuously without requiring rethreading of the tube into the bending rolls.

Title: Heat meter for domestic radiator - uses viscous liquid flowing from tank to graduated tube through capillary tube placed against radiator
IPC: G01K17/02
Filed: 1982-01-11
Abstract: This apparatus, when fixed on a domestic radiator, measures the quantity of heat emitted by this radiator during a certain period. This apparatus is formed by a tank which contains a viscous liquid which flows by gravity in a graduated tube situated under the tank. The quantity of liquid in the graduated tube indicates the heat emitted. In this apparatus, the liquid flows through a calibrated capillary tube which is placed outside the tank and outside the measuring tube. The apparatus is mounted on the radiator in such a way that this capillary tube is placed against the radiating surface. A heat insulating device is placed so that the temperature difference between the capillary tube and the radiating surface is low.

Title: Stackable foodstuff trays - have posts and half height side walls stacked post on post for delivery and offset when empty to half stack vol.
IPC: B65D21/04
Filed: 1982-04-08
Abstract: The receptacles or trays (1) are used to deliver foodstuffs such as cheeses, stack one upon another when carrying food, and stack in a different more compact manner when empty. The costs of returning empty trays are reduced. Each receptacle may have side walls (1) with posts (5) projecting above at intervals, the upstand of the posts above the walls being approximately equal to the height of the wall. A stack of directly superimposed trays with their legs in vertical alignment thus presents continuous segmental posts with tray walls (1) alternating with voids of the same area. Once the posts of alternate trays are moved into a horizontally offset relationship, the walls (1) rest on each other to reduce the empty stack to half the vol.

Patent FR-2514208-A1 (FR)
Inventor: OEHLERT WOLFGANG
IPC: H01R39/40
Filed: 1982-06-02
Abstract: The invention relates to a carbon-brush holder for electrical machines having large dimensions, which carbon-brush holder (as a modification from the metallic construction, consisting especially of cast brass, which was previously regarded as being necessary) consists of a plastic having the necessary mechanical, electrical and thermal properties, and only suitable metallic profiles, which are pressed into the plastic body, are provided as guides for the carbon brushes. In consequence, considerable savings can be made both in terms of material and in terms of production, and, above all, the carbon-brush holder is considerably lighter than a metallic carbon-brush holder.

Title: Retractable garage door
IPC: E05F15/16
Filed: 1983-02-21
Abstract: This retractable garage door made up of one single panel is vertical in the closed position but becomes essentially horizontal and close to the ceiling in the open position. The movement is achieved by the traction of a cable 9 fastened on either side at the bottom of the panel and after a plurality of return pulleys, being wound around a double-winding drum. The bottom of the panel 4 slides along a vertical rail 1 and the top along an oblique rail 2. The drum is rotated by means of an electric motor but can be rotated, in the event of a power failure, by hand. The very simple mechanism does not comprise any pivoting axle, any counterweight, any springs or any connecting rods. This type of gate which never juts out into the street, and which does not substantially decrease the capacity of the garage, can be used for other buildings where similar problems occur.
