Title: Multi-layer circuit board fabrication
Inventor: LANDO DAVID JACOB
IPC: H05K3/34
Filed: 1982-12-03
Abstract: Printed circuit boards having a plurality of circuit layers are produced using a specific processing sequence. A copper-clad substrate (31) is first patterned in a desired configuration to produce the first layer of the printed circuit board. The patterned metallization (32) is then covered with a specifically formulated energy sensitive material (Fig. 3B). The energy sensitive material is delineated in a desired pattern and developed to uncover portions of the underlying metallization pattern. The entire substrate is blanket-cured to produce a rigid layer having openings in appropriate places. The openings are metallized (34, 35) and a second copper pattern is produced on the cured polymer by conventional metallization and lithographic techniques. If desired, the process is repeated until a suitable number of copper patterned levels are obtained.

Title: Machine for washing and drying domestic laundry
Inventor: CASH PETER
IPC: D06F58/24
Filed: 1985-10-02
Abstract: A machine for washing and drying domestic laundry comprises a cabinet (3) containing a stationary cylindrical tank (1) for holding washing liquor and a rotatable perforated drum (2) within the tank in which the laundry is washed and subsequently tumble-dried. For drying the laundry a stream of hot air produced by a fan (26) and heater (27) flows through a narrow duct (28) into the drum, the moist air leaving through an outlet (21) in the bottom of the tank which also serves for the removal of the dirty washing liquor. After being dried in a condenser (30) the air returned to the fan for recirculation in the machine. A small high-speed fan is used which delivers air at high pressure and velocity so that air ducts of small cross-section can be used. The fan and the heater are housed in a box which is attached to the back of the cabinet. With this arrangement, and the use of small-section air ducts, a standard washing machine can readily be converted into a washer/dryer. <IMAGE>

Title: An electric oven
Inventor: BOUILLET ANDRE
IPC: F24C15/02
Filed: 1986-03-26
Abstract: An electric oven has a number of heating elements for heating the cooking chamber. A multi-position switch is arranged to couple power to all of the heating elements, such that the chamber can be used as an oven, or to only selected heating elements such that a grilling operation can be performed. However, when grilling it is best if the door of the cooking chamber is at least partially open so that air can circulate.
