Title: Improvement in jars or other containers sealed by a vacuum
IPC: B65D41/04
Filed: 1928-10-18
Abstract: 318,213. American Metal Cap Co., (Assignees of Hammer, C.). Aug. 31, 1928, [Convention date]. Bayonet-joint stoppers; vacuum closures.-The necks of glass containers are provided with cams which give an initial lift to break the vacuum on backward rotation of the cap. The container 2 has four threads 3 which cooperate with lugs or projections on the cap, and cams 5 situated at the tail ends of the threads are provided to give the initial lift. In a modification; the cams are separate from the threads, and are situated on the shoulder 7 of the container. Stop-faces 9 limit the turning movement of the cap. When the cap is applied to a container the locking lugs ride down the underside of the threads to the stops 9. On backward rotation of the cap, the lugs, due to the vacuum, turn back in the same plane as they are locked until they reach the cams, when the desired vacuum breaking lift is imparted thereto. Specifications 225,922 and 280,853 are referred to.

Title: Improvements in and relating to time control means for electrically heated receptacles
IPC: H05B1/02
Filed: 1953-11-06
Abstract: 737,838. Electrically heated receptacles. GENERAL ELECTRIC CO. Nov. 6, 1953 [Nov. 6, 1952], No. 30806/53. Class 39 (3). [Also in Group XXXVII] An electrically heated receptacle has heating circuit control means comprising a switch coupled with an operating member by a fusible substance enclosed within a casing, means being provided for adjusting the heat conductivity between the receptacle and said casing whereby to allow operation of the switch by biasing means therefor in response to adjustable predetermined temperature conditions in the receptacle. A coffee percolator has three heating units 3, 4, 5 of which 3, 4 are controlled by switch contacts 6, 7, 8 operable-by an annular cam 21 forming part of a casing 15 which is screw-threaded at 30. The cam 21 carries a pointer 25 and houses a coil spring 22 which normally urges the cam to the position shown in Fig. 3. A control shaft 17 provided with an operating knob 18 has a portion surrounded by a fusible substance 19 in the casing 15 and a friction drag for the shaft 17 is secured to a wall of the percolator. Manual rotation of the shaft 17, when the substance 19 is solidified, enables the distance separating the percolator wall 11 from the casing wall 16 to be varied to alter the heat conducting path between the walls. To operate the percolator the shaft 17 is turned such that the pointer 25 is set at any point between " weak " and " strong " on the scale, Fig. 7 (not shown), i.e. in accordance with the length of time for which percolation is desired, the friction drag retaining the shaft in the set position against the action of the spring 22. Heating units 3, 4 are thus brought into circuit in addition to the unit 5 which is permanently connected across terminals 9. At the end of the percolating period the substance 19 in the casing 15 fuses, the spring 22 turns the casing, cam and pointer back to the " keep warm " position, and the heating units 3, 4 are open-circuited again. For reheating cold coffee already made, the pointer is set to " reheat," Fig. 5 (not shown), the " high heat " unit 3 thus being connected in circuit. The unit is disconnected when the substance 19 reaches fusing temperature. In a modification, Fig. 8, a plate 31 is fixed to the inner wall 11, and a movable plate 33 is biased into engagement with plate 31 by a spring 35. The extent of overlap of the plate 33 with plate 31 determines the heat conductivity from the wall 11 to the fusible substance in the casing.
