Title: Improvements relating to security switches
IPC: G08B13/12
Filed: 1982-03-24
Abstract: A cable 3 forms part of a loop alarm and the circuit is completed when two conductor leads of the cable 3 entering a housing 2 are interconnected by contacts 6A,9A,10A. The housing 2 may incorporate curved passageways 2A which receive a ring 1 having a gap within which is positioned a bolt 4 carrying a contact 6A. The end 11A of the bolt 4 can be pressed inwardly against spring bias 5 so as to align a passageway 4A with passageways 2A, thus enabling the ring 1 to be rotated to expose the gap to enable a piece of merchandise to be removed or linked onto the ring. Whilst in this condition the contact 6A is no longer in contact with contact strips 9A and 10A and the loop alarm will therefore be in an alarm condition. Alternatively, the conductive leads of the cable may be electrically interconnected by a conductive ring member or conductive portions on a ring member which is slidable into and out of the housing. <IMAGE>

Title: Embossing fabrics
Inventor: MYERS STEVEN A
IPC: D06Q1/08
Filed: 1983-07-01
Abstract: A method of embossing a fabric containing keratinous fibres, particularly lambswool or botany knitwear, in which a stabilising agent, for example a shrink resist resin, for the keratinous fibres is applied by exhaustion followed by embossing the material.
