Title: Reinforced domestic tissue band - has transverse arrangements of slits which sever reinforcing strands and form tear lines
IPC: A47K10/16
Filed: 1975-09-24
Abstract: The reinforced tissue band has pre-determined transverse tear lines which dictate lengths of band which may be torn off for use. The tear lines are delineated by the formation of many individual slits. The geometrical arrangements of slits ensures that all the reinforcing strands in a particular transverse section are severed. The band comprises two layers of tissue sandwiching a grid of reinforce ng strands. Tear lines in bands with a squarely orientated grid (13, 14) may be formed by a transverse line (10) of 45 deg. orientated slits (11). The slits (11) overlap by say 50% of their length in the transverse sense.

Title: Prodn. of electric stack or layer capacitor - using metal layers on synthetic dielectric layers wound about drum in stretched condition
IPC: H01G13/00
Filed: 1975-11-07
Abstract: In a process of producing capacitors, synthetic dielectric layers carrying metal layers are wound, ion a stretched condition, about a drum to form a mother capacitor. Individual capacitors are then formed by sawing, with a rotating saw blade through the mother capacitor. Due to the heat which is developed during sawing, the stretched layers contract in the region of sawing causing a break up of the metal layers which then oxidise to form insulating islands. This process is improved by applying an insulating lubricant to the saw blades to increase the dielectric strength of the capacitors at the saw cuts.
