Abstract: 1449666 Coated fabrics W C HELLER 28 Sept 1973 [20 Oct 1972] 45544/73 Heading B2E [Also in Divisions B4 and B5] A material for heat-sealing two bodies 12, 14 having bonding incompatibility comprises an integral layer of strands 27 at least partly embedded in each of layers 22, 24 which are heat-sealable to bodies 12, 14 respectively but not to each other, at least one of layers 22, 24 having dispersed therein a particulate susceptor heatable upon exposure to indirectly applied energy. In a preferred embodiment for bonding a polypropylene sheet 12 to a nylon eye fastener 14, layer 22 is of polypropylene, layer 24 is of nylon and the strands 27 constitute an open-weave glass fibre fabric. One or both of layers 22, 24 may be rendered susceptible to heating by high-frequency magnetic or dielectric heating by incorporating magnetic particles, e.g. Fe 3 O 4 , gamma-Fe 2 O 3 . CrO 2 , or dielectric particles, e.g. polymers and copolymers of vinyl or vinylidene chloride or fluoride. The particulate material may be incorporated by calendering and or extrusion. As shown, particulate material 28 is present only in the layer 24 having the higher heatsealing temperature. The strands 27 may be so embedded that the layers 22, 24 are spaced apart or contacted in the fabric interstices. Contact may be improved by coating the weft and warp with the materials of layers 22, 24 before the fabric is woven. The embodied material is made by softening the layer 22 on a heating plate or by indirect energy, applying the fabric of strands 27 with pressure if necessary, and applying the layer 24 as a melt or solution by casting, extrusion, spraying or brushing. If desired, both layers may be applied as softened solid layers or both in liquid or solution form. The material may be hotpressed to reduce its thickness. One or both of layers 22, 24 may be pigmented. Other suitable materials for the layers are listed, and the woven fabric may be replaced by a roving or knitted fabric.

Title: Automatic load dependant switch for domestic installation - isolates house wiring network when no domestic demand exists and substitutes low voltage supply
Inventor: PALM HUBERT DR MED
IPC: H02H3/12
Filed: 1974-03-09
Abstract: The object is to reduce biological disturbances caused by the emanation of stray electromagnetic and electric fields from domestic wiring, when there is no demand on the house system, for example at night. A relay under the control of a current transformer keeps the supply on for as long as a load is connected. Removal of the last load trips the supply and puts a small voltage, typically a few volts d.c., on the system which can have no biological effects. The reconnection of a load results in a signal current to the controlling amplifier which causes the relay to operate to restore mains supply and trip the low voltage. To eliminate cycling at very low load currents which are insufficient to hold in the relay, a cycle counter and lockout feature may be provided.
