Patent FR-2377459-A1 (FR)
Title: Electrostatic spraying enamel powder onto hollow objects - esp. to obtain uniform coating on the lids of domestic cookers
Inventor: LACCHIA ADRIEN
IPC: B05B5/12
Filed: 1977-01-12
Abstract: A hollow object, consisting of a flat base with a rim, is suspended so the base is vertical, and is then sprayed with electrically-charged enamel powder. During spraying, a gas stream is directed onto the lowest inner part of the rim, and a second, local spraying operation is then used to coat the lowest part of the rim with powder. An auxiliary spraying operation may also be used to coat the inner surface of the highest part of the rim, but the latter is pref. coated during the main spraying operation. The pref. plant uses a conveyor for the vertical suspension of the objects, while they travel past nozzles spraying powder onto the base and the inner surface of the upper rim; another nozzle blows a gas stream onto the lowest inner part of the rim. The lowest part of the rim is then coated by yet another nozzle. Used for the electrostatic spraying of enamel powder, e.g. onto the lids of kitchen stoves. The influence of gravity normally prevents a uniform powder coating; the invention eliminates this problem.

Title: Injection nozzle converting single into multiple plastic streams - which is heated and can connect to mould or machine
IPC: B29C45/22
Filed: 1977-06-24
Abstract: An injection nozzle which distributes a single stream of plastic into a number of streams. The system includes two members, a plastic receiving member and a plastic discharge member which are connectable in a telescoping relationship. The receiving member has a central plastic receiving opening which extends into a number of channels. These channels connect with a similar number of channels in the plastic discharge member which in turn connects with the mould. The nozzle is cheaper to produce and a complete nozzle is not required for each mould because the receiving part be disconnected from the discharge part.

Title: Melt impression of thermoplastic sheath for flexible linkage cables - for securely keying terminal fitting to sheath
IPC: B29C65/08
Filed: 1978-01-13
Abstract: Fittings for the ends of a reinforced plastic sheath for a flexible cable, i.e. for linking a rotary or reciprocating mechanism, are secured by mechanical engagement in recesses produced in the surface of the sheath by an ultrasonic heating tool. The tool is applied radially until stopped by the resistance of the metallic reinforcement with the sheath body. The example describes hot impression of a polyethylene cover which enclose a metallic mesh surrounding a sheath core tube of e.g. polyamide resin. The sheath bore may be supported internally while its outer surface is impressed by the ultrasonic probe. Melt drilling leaves the sheath relatively free of residual internal stress.

It can be cast or forged into resistances for industrial furnaces operating at >=1300 degrees C. The alloy has good forgability (the fine grained two phase structure compensates for the unfavourable effects of Al), high oxidn. resistance (the Fe addn. reduces wt. loss by spalling of protective oxide films) and high heat resistance. The electrical resistivity of the alloy is >=85 mu OMEGA cm. The alloy has higher solidns. temp. and better forgability than known austenitic alloys.

Title: Refrigeration circuit utilising heat dissipated by condenser - uses condenser cooling water to supply central heating system
IPC: F25B29/00
Filed: 1978-05-10
Abstract: A refrigeration circuit consists of a compressor (16) which supplies refrigerant to a condenser (17 or 18). The liquid refrigerant passes through the reservoir (19) the drier (20), the sight glass (21), the expansion valve (11), and evaporator (12) to return to the condenser (16). To use the heat dissipated by the condenser, it is cooled with water through the pipes (22). Using cooling water enables the condenser to be placed in any convenient position (e.g. 171). The heat in the cooling water is removed by a fan and the air used for heating purposes elsewhere. This heating can be supplemented with hot water, from a tank controlled by a valve. When heating is not required, the secondary condenser (18) is used which is air cooled by the fans (32).
