Title: Sliding clasp fastener prodn - by prising open slotted members into y-shape
IPC: A44B19/08
Filed: 1971-02-10
Abstract: A method for making sliding clasp fasteners from plastics, where each unit comprises a pair of symmetrical coupling heads, one on each side of the line of the fastener and aligned with each other transversely across it and with an intermediate piece between these heads to fit between the complementary pair of heads on the other side of the closure and prevent lateral displacement of the two sides, one in which first, a row of coupling units is formed, each unit consisting of an intermediate piece and a pair of coupling heads on either side, these heads being slotted transversely to the line of the closures, and wedges are then pushed into the slots of each of the heads, prising them open into a Y-shape. In the preferred appts., a string of coupling units forming one side of the closure, with the transverse slots already formed in the coupling heads, is carried on an endless belt, while a second endless belt converging towards this presses wedge-shaped inserts into the slots, thus prising them open into the Y-shape. The string of coupling units is then passed to a second pair of belts where it is cooled.

Title: Self-excited machine with two separate stator windings - windings star-connected with second capacitively closed for excitation
Inventor: KRIM-SAMHALOV IZMAIL
IPC: H02K17/42
Filed: 1974-01-08
Abstract: The self-excited machine, e.g. generator, has capacitors coupled to its first stator winding and the load coupled to its second stator winding.
