Patent FR-2340626-A1 (FR)
Title: Electric battery with integral hood and sheath - has annular sheath zone fitting tightly constricted vessel neck
Inventor: JAMMET JEAN
IPC: H01M6/08
Filed: 1976-02-09
Abstract: A cylindrical electric battery comprises a metal vessel formed by a bottom and a side wall, closed by a plastic cover integral with a plastic sheath enclosing the metal wall of the cell. The sheath has an annular zone close to the cover, thicker than the rest of the sheath and separated from it by an inner shoulder. This zone is in tight contact with the side wall of the vessel whilst the remainder fits with a certain amount of play, andis in cntact where the vessel has a smaller diameter than the body of the vessel. The thicker annular zone is produced during the moulding in one piece of the cover and the sheath, or it may be applied by overmoulding a tubular blank for the sheath with the plastic mass forming the cover. Alternatively the thicker zone may be formed by welding a piece forming the cover on to the blank for the sheath. An efficient seal between the bottom of the cell and its wall is long standing, but a better seal for the top, preventing leakage of the electrolyte between vessel and sheath and elsewhere outside, would make batteries cheaper to manufacture. A known seal is obtd. by shrinking on an "L"-section ring; the present proposals achieve the seal more easily and without using a separate piece.

Title: Electromagnetic brake with AC generator for vehicle - has load windings and current-generating windings both mounted on rotor
IPC: B60T13/74
Filed: 1976-04-12
Abstract: The electromagnetic brake with ac generaor, for vehicles, has a permanently magnetic rotor with its poles arranged north-south, all south or all north as requird. The rotor's speed can be increased by a suitable choice of the number of teeth on the central ring forming part of the support for the permanent magnets towards the outside. The load windings are perpendicular to the windings carrying the generated current. The load windings load the generating windings and transform the electric field into a magnetic field and restore braking between the rotor and the vehicle's brake drum. The load and generating windings are both on the rotor and require no external connections.

Title: Microwave heating of foods while immersed in liquids - esp. in water, for equalising the temp., is suitable for sterilising or defrosting
IPC: A23L5/10
Filed: 1977-02-18
Abstract: Foodstuffs in the form of pieces or portions are heated by applying microwave radiation to the portions as they are continuously conveyed. In the region where the microwaves are applied to the food, the food is immersed in a liq. medium, esp. water. Where the microwave treatment is intended for sterilising the food, the water is pref. maintained at 80-90 degrees C; where, however deep-frozen foods are being thawed out, the water is pref. maintained at about 5 degrees C. Where the microwave treatment is for pasteurising packaged foodstuffs, esp. precooked foods the packages are immersed in the water before the application of the microwaves and not removed from it until after the application ceases. The use of a flowable medium, esp. water, around the articles while they are subject to microwave treatment provides a very high degree of temp. equalisation, thus preventing hot spots resulting in overcooking or damage to the food. At the same time, the power loss involved is only is approx. 20%.

Title: Guiding the deflection of stretched cables - using stack of relatively movable rigid, circular members which eliminate distortion of cable against support wall
IPC: F16G11/00
Filed: 1977-12-30
Abstract: The deflection of a stretched cable which leaves a mass perpendicularly is guided by a device having a flared channel which surrounds the cable. The cable strands of the cable portion which pass through the channel engage members which are capable of a certain variation in angular position with respect to one another. The members comprise flat, rigid rings between which annular layers of solid, elastic elastomeric material are interposed. The cable strands pass through the rings. Used for guiding the deflection of cables, such as stays, mooring cables, cable-ways or cable bridges. The stack of rigid members present a certain longitudinal flexibility which enables it to be adapted to the curvature of the flared channel wall and transmit transverse forces due to the curvature of the cable. The stack maintains the cable strands in relative mutual posn. and retains the geometry of the cross-section of the cable.
