Title: Thermoplastic socket joints for conduit having metallic reinforcement - by ultrasonic welding to reinforcement exposed by removing its sheathing
Inventor: GUIDICELLI CHARLES
IPC: B29C65/08
Filed: 1982-05-04
Abstract: Joints between a metal reinforced cable conduit and a thermoplastic conduit socket are effected by removing external sheathing material from the conduit to expose the metallic reinforcement near the end of the conduit, inserting the conduit end into the socket, and applying an ultrasonic welding tool to part of the socket walls to fuse the bore of the socket on to the exposed metallic components of the conduit. Esp. claimed for joints where the socket is of polyamide, the ultrasonic welding tool pref. being operated at 18-20 kHz. Ensures a positive key between socket and conduit without inducing torsional or flexural strains characteristic of forcing a full-sized conduit end fully home into a socket joint.

Title: Solar heating for a building with a veranda - air recirculated until desired temperature is reached
Inventor: DEENEUVELE DANIEL FLORENT ANDR
IPC: F24D11/00
Filed: 1982-05-10
Abstract: The veranda has a double glazed facade (2), a low pitch roof (3) with integral solar captor (11), a sill fixing it to the building wall and a sill (6) carried by the facade framework (7). Light rays (36) strike the facade and preheat the air which is then sent to the roof captor for more heating. When the air temp. as detected by a thermostat (35) is too low, a circulator (33) distributes the warmed air back to the facade interior and the solar captor repeatedly to attain the temp. required. When the air reaches a required temp. a distributor (29) sends it to a store (32).

Patent FR-2533015-A1 (FR)
Inventor: ROULLET ALAIN
IPC: B65B31/00
Filed: 1982-09-13
Abstract: Containers 6, adapted to receive a product which does not of itself give off a gas, receive an amount of a liquefied pressurizing gas from a tank 1 provided with an outlet nozzle 3. The containers 6 are aligned on a machine 7 which conveys them, in the direction of the alignment, under the tank 1 which is provided with trunnions 2 and is oriented in such manner as to be pivotable about an axis parallel to the direction of alignment. A control device 8 regulates the angular position of the tank 1. The amount of the liquefied pressurizing gas received in each container depends on the angular position of the tank relative to the vertical position. Thus, in the case of containers having a round section, the amount of liquefied gas received in a container is maximum when the nozzle is on the line of alignment of the containers and passes along a diameter of the container section and smaller when the tank has been pivoted away from its vertical position and the nozzle passes along a chord of the round container section. The invention is particularly applicable to the pressurizing of cylindrical cans adapted to contain non-gaseous drinks.

Title: The motion of the body in the region of the force of its permanent magnetic field
IPC: H02K53/00
Filed: 1984-01-17
Abstract: The invention relates to a device making it possible to transmit a motion to a permanent magnet body in the region of the force of its permanent magnetic field characterised in that it consists of a permanent magnet 1 fixed to a four-roller carriage 2 which moves over the rails 3. A balance mass 4 with a weight of 1/100 of the magnet-carriage force will be fixed onto one of the sides of the magnet-carriage, the latter will attract an iron block 6 whose weight equals the force of the magnetic field of the magnet-carriage at a distance of 0.5 mm 7. In this journey the iron block gains weight in accordance with the force of the magnetic field 14. At this moment the weight of the iron block is transmitted to the rollers of the carriage element 8 and in the initial location of the iron block a lever 12 which was held by the weight of the iron block prior to its displacement is freed. About half such a pulling weight 10 is sufficient to displace the magnet-carriage which is subject to the weight of the attracted iron block and to half the force of its magnetic field, from the position AB to the position A<1>B<1>. During this journey the magnet-carriage passes over the iron block of the same fixed size 11 in the vicinity of the point C, by which it is partially attracted. The attracted iron block will be outside the region of the force of the magnetic field and will fall in the initial location, onto the lever 12 whose other half is subject to the weight which is equal to that of the iron block 13.

Title: Apparatus for changing valves under pressure
IPC: F16L55/132
Filed: 1984-06-29
Abstract: The invention relates to an apparatus which makes it possible to change valves under pressure without having to remove this pressure. It comprises a valve plug 1, traversed by a tube 2 containing a stem 3 comprising a stop 4 and a threaded portion equipped with a nut 5, carrying at its end a cylindrical stopper head 6. The mounting of the plug 1 allows the valve to be opened and the stopper head to be positioned in the duct 7 in which the valve is mounted. Screwing the nut 5 whilst keeping the stem 3 stationary gives rise to a reduction in the length of the cylinder and an increase in its diameter and hence the stopping of the duct 7, allowing the plug 1 and the valve to be dismantled. The apparatus can be used in liquid-storage industries, and especially in the marine environment where it constitutes an important element for the safety of ships.
