Abstract: 851,846. Respiratory appliances. AIR REDUCTION CO. Inc. July 15, 1959 [July 16, 1958], No. 24371/59. Class 81(2) [Also in Group XXIX] An emergency oxygen supply system for high altitude use incorporates a supply valve which is released to open when a mask is taken from its storage position for use. The equipment is normally housed in a container 24, Fig. 1, with the face mask 16 held by a clip 32 on the hinged door 26. The mask is connected to the supply valve 10 through a breathing bag 14 and flexible tube 12 but a projecting stem 88 of the valve is held down, to keep the valve closed, by a blade spring 38 bearing down on a ball 36. This ball is connected to the mask by a cord 34, or other linkage, so that when the mask is pulled clear by the user, the ball is pulled away from its seating and the valve is allowed to open, so passing oxygen to the mask. Oxygen is supplied to the valve through a conduit 46, Fig. 5, which is clamped over the tubular valve body 58 by a cap nut 62. It passes through a cut-away portion 70 to the bottom of the tubular body and then up through a filter element 74 to the valve seating. The sliding valve head 84 normally closes this owing to the spring 38 pressing the ball 36 down on to its stem 88, but, as soon as the ball is disengaged, the valve is opened by upward pressure of a spring 561 and oxygen passes out through the connection 55 to the face mask. In one modified form, Fig. 12 (not shown) the ball is replaced by a wedge-shaped key while in another, Fig. 13 (not shown) the ball is formed as part of the flexible air tube.

Title: System for delivering alarm calls or signals over the connecting lines of telephone installations
IPC: H04M11/04
Filed: 1927-09-16
Abstract: 277,960. Siemens & Halske Akt.-Ges. Sept. 21, 1926, [Convention date]. Fire, police, and like alarm systems and apparatus.-In an automatic telephone system in which alarm stations are reached over the tenth levels of the switches at one of the stages, these switches are arranged to suppress one of the impulses of the first train they receive, thereby rendering it impossible for ordinary subscribers to make alarm calls, whereas stations required to make such calls are equipped with special impulse senders capable of sending a train of eleven impulses. The invention is described as applied to a system in which alarm stations are reached over the last levels of the second selectors IIGW. Alarm sending substations such as N are equipped with automatic clockwork impulse senders, which upon the depression of a button rotate cam discs which first operate contacts 1y1, 2y1 to disconnect the subscriber's instruments, and then at contacts 4y2 send the trains of impulses required to route the call to an alarm station and give a code indicative of the station calling. Eleven impulses are sent to the group selector IIGW to raise it to the tenth level, the first impulse being suppressed since the slow-release relay F, which prepares the circuit of the vertical magnet H. is not energized until the line relay A2 relapses after the first impulse. When the relay A2 pulls up in response to the second impulse the magnet H is energized over contacts 28a2, 29f. A signal SZ across the substation conductors indicates when the connection has been switched through.

[Also in Group XXXV] An energy regulator of the type which periodically breaks the circuit for variable intervals is further provided with an additional means to modify the on-off ratio to increase the initial flow of current. The regulator which may be of the thermal or motor-driven type comprises contacts 13a, 13b, which in the latter case are axially displaced by a cam 18 driven from a synchronous or clockwork motor through a gear train. A further gear train rotates. a clutch member 36. The other clutch member 42 rotates freely on a shaft 28 and is pushed into engagement by a spring 43, and a peg 33 transmitting thrust from an inclined track on a cam 34, 35, the two parts of which are connected by a ratchet, part 35 being rotated by a knob 29. In addition, knob 29 determines the on-off ratio by the axial positioning of contact 13a through a further cam 27. The sequence is established by rotating knob 29 fully anti-clockwise and then clockwise to the setting required. This rotates cam member 34 unidirectionally causing peg 33 to ride up the track engaging the two parts of clutch 36, 42, which drives the peg back to its original position, during which time a pair of contacts 14a, 14b in parallel with contacts 13a, 13b and coupled to clutch assembly 30, 42, 43 are closed. Contacts 13a, 13b may alternatively be actuated by a thermally responsive bimetallic element. A thermostatic switch is provided to open the circuit should the oven temperature become excessive due to manual operation of knob 29 when the oven is hot. Contacts 14a, 14b may be eliminated if a suitable linkage is provided to hold contacts 13a, 13b closed during the initial warming period, and the variable time setting may be replaced by a fixed time setting by incorporating a further ratchet to give a fixed angular displacement of member 34 irrespective of the angular rotation of knob 29. Specification 818,371 is referred to.

Abstract: 765,708. Magnetic switches. TRIST & CO., Ltd., R. Aug. 25, 1955 [Aug. 25, 1954], No. 24743/54. Class 38(5) A switch responsive to high and low water levels in a boiler to switch "off" and "on" a feed pump at these levels, has an adjustment whereby it may be adapted to suit boilers having different ranges extending between the two levels. The switch comprises a casing 1 having a cylinder 2 open at its lower end and receiving a slidable container enclosing a permanent magnet 8, the container being operable by a float in the boiler through a rod 10. The magnet 8 operates by repulsion a permanent magnet 23 pivoted at 25 on a member 32. The magnet 23 carries a mercury switch 28 whereby on lowering of the magnet 8 from the position shown the switch 28 is tilted clockwise at the low water level so that the mercury bridges electrodes 29. Similarly when the magnet 8 has been raised to the high water level the switch 28 is tilted counterclockwise to disconnect the electrodes. To accommodate for different water level ranges the permitted degree of tilting of the magnet 23 is adjustable by a slotted arm 35 movable with the magnet and having a stop pin 36 adjustable in the slot and co-operating with the sides of a V-shaped opening 33 in the member 32 The switch assembly is set so that the pivot 25 is at the mean position between the high and low levels this setting being performed by adjustment up or down of the assembly on a slotted bracket 13 in the casing 1, the member 32 being clamped in the mean position to the bracket by a nut and threaded stud (not shown). In a modified arrangement the bracket 13 is omitted and the cylinder 2 is fixed to the boiler, the casing 1 being movable up and down on' the cylinder for adjustment to the mean position. A further magnetic switch assembly 18 may be provided for operating a low water level alarm, but this assembly does not include the adjustment means 33, 36. In a modified construction of the adjustment means for limiting the degree of tilting of the magnet 23 (Figs. 2, 3, not shown), an arm corresponding to the arm 35, but unslotted, cooperates with the sides of a V-shaped opening lying in a horizontal plane and provided in a member adjustable in that plane whereby the distance between the arm and the apex of the V may be varied.
