Title: Improvements in or relating to buckets or like receptacles
IPC: A47L13/60
Filed: 1933-10-19
Abstract: 418,864. Mop wringers. ROTHERHAM, G. H., 7, Spencer Hill, Wimbledon, London. Oct. 19, 1933, No. 28968. [Class 19.] A mop wringer in which a movable roller 7 engages an arcuate plate 2 is characterized in that resilient means are provided to afford a variable distance between roller and plate. A receptacle 1 of rectangular formation has the perforated plate 2 pivoted at 3. The upper end of the plate has a transverse rod 4 extending through arcuate slots 4<1> in the receptacle and engaging helical springs 5 fixed at 6. The roller 7, preferably of rubber, is mounted on arms 8 of a frame 9 pivoted at 10. The frame is provided with an operating handle 12. The resiliency of the springs prevents the upper part of the mop being pressed too hard. Instead of the springs 5, a compression spring may be placed between the plate 2 and the walls of the receptacle. In a modification, the pivot 3 may be spring mounted, or the roller, or the roller frame pivot. Specification 379,946 is referred to.

Title: Complementary mosfet device
IPC: H01L27/08
Filed: 1976-07-14
Abstract: The CMOS semiconductor circuit contains a first zone (1) of a first conductivity type with a second zone (2) formed therein of opposite conductivity type. In the first zone (1) there is formed a first MOS transistor (Q1), and in the second zone (2) there is formed a second MOS transistor (Q2) of opposite channel conductivity type. The source of at least one of said two MOS transistors (Q1, Q2) is connected electrically to the zone in which said MOS transistor (Q1, Q2) is formed. In this arrangement, the first zone (1) can be a semiconductor substrate, and the second zone (2) can be an island, the source of the first MOS transistor being connected electrically to the substrate. By virtue of this connection it is possible to prevent continuous currents triggered by spikes from being established which could destroy the circuit. <IMAGE>
