Title: Pressure operated electric switching mechanism
IPC: H01H35/26
Filed: 1965-11-12
Abstract: 1,083,660. Thermal switches. RANCO Inc. Nov. 12, 1965 [Jan. 15, 1965], No. 48218/65. Heading H2B. A pressure-responsive control device, e.g. an adjustable thermostatic control for airconditioning or cooling apparatus, comprises a housing 11 mounted on the apparatus and containing a snap-action switch 13. Switch contacts 13a, 13c are actuated by toggle spring 17, 17b, part 17 having a portion extending through a tab 13d on arm 13b, said actuator 17 biasing the contacts apart. Contacts 13a, 13c are closed on depression of a button 18. An expansible capsule 20 depresses the button 18 through a resilient strip-like beam 21 opposing capsule expansion. The beam 21 is adjustably supported at one end by a screw 23 carried by an adjustable lever 24 (Fig. 1,) pivoted at 24b. The tension in the beam 21 is adjustable by a cam 26, rotatably mounted on the housing front wall 11h and engaging an arm 24c on lever 24. Cam 26 (Fig. 5), has a section (26e) which on engagement with arm 24c puts maximum force on beam 21 and hence provides an " off " position. Another section (26c) puts minimum stress on beam 21 and switch 13 is permanently closed. A further section (26d) provides a varying force and hence a range of operating temperatures. An auxiliary fan switch (30, Fig. 3), is provided comprising normally closed contacts (30a, 30b) which open when a rise (26f) on cam 26 engages a button (30e) on an arm 30c, at which time switch 13 is " off.". In a modification, (Figs. 6-8), the cam (53) is mounted on the housing top wall (lid) and the arm (51c) of the lever (51, Fig. 6) passes through an opening (21b) in the beam 21 to engage the cam (Fig. 7). When the switch is in the " off " position, arms 151d, 51e (Fig. 6) on the lever (51) engage lugs (57, Fig. 6) on the beam.

Filed: 1973-10-19
Abstract: 1432980 Rupturable containers POLAROID CORP 19 Oct 1973 [25 Oct 1972] 48863/73 Heading G2X A rupturable container holding photographic processing material is divided into a number of compartments, the compartment at each end being trapezium-shaped, the shorter of the parallel sides of each trapezium being the rupturable edge. As shown, the container is divided into three separate compartments or pods 21. Under pressure, these rupture along the forward edge 22. The outer pods 24 are trapezium-shaped, with the shorter parallel edges weakened during manufacture so that these are the edges which rupture and through which the processing material passes out. This arrangement produces a more uniform distribution of the processing material over the area to be covered, ensuring that the outer corners are adequately supplied.

[Also in Division D1] In apparatus for shearing the surface of a moving fabric web 12, the edges 31, 33 of the web are uncurled before reaching the shearing devices by a pair of members 22 providing endless surfaces, e.g. endless bands, driven in opposite directions, one member being situated adjacent to and transversely of each web edge so that sections of the members will move laterally outwards over the edges to uncurl the edges and enable the web to be sheared uniformly. The shearing is effected by helical cutters 16 which shear protruding fibres to a uniform height. A fixed support 56 is provided for the web where the bands 22 engage the web. Pulleys 24, 26, 28 carry each band, the shaft 44 of the outer pulley 28 being motor driven. Each belt may be pivoted about the shaft 44 so that the shafts 40, 42 of the other pulleys 24, 26 can be adjusted in slots in a frame member 32 to vary the distance of the belts from the web and the inclination of the belts to the web. In a modification, each belt extends more than half way across the web and may be provided with bristles, so that the surface of a cloth web is brushed across its entire width prior to its reaching the shear cutters 16. The crossbrushing may be used in co-operation with cylindrical raising brushes to enhance the finish.
