Abstract: 1,027,785. Telegraphy. SIEMENS & HALSKE A.G. Jan. 19, 1965 [Jan. 20, 1964], No. 2256/65. Heading H4P. In an exchange in which any one of a number of incoming lines may be connected to any one of a number of outgoing lines via any one of a number of stores, the transmission speed on the outgoing line is determined by a clock associated with the line. Received characters pass to a core store and, when their transmission direction and priority have been established, are passed to an intermediate magnetic store. Each intermediate store may include several messages for the same destination. An auxiliary circuit takes account of the message priority and of the time for which a message has been held in the intermediate store, and sets up a connection to the outgoing line. A clock generator forming part of the outgoing line transmission unit controls the speed of onward transmission.

Abstract: 1521922 Helicopter rotor spar pressuresensing system UNITED TECHNOLOGIES CORP 21 Jan 1976 [12 Feb 1975] 02305/76 Heading B7W In a helicopter rotor assembly 10, the physical integrity of pressurized spar assemblies 12 is monitored by a system comprising pressure transducers 24 for sensing a reduction in the internal pressure of the spar assemblies, slip ring assemblies 30, 34 having rotating elements 28, 32 connected to the transducers 24 by a liner 26a-26d and stationary elements 42, 52 connected to a fault indicator 46 and a switch assembly 50 respectively, the switch assembly having a contact 48 connected to the fault indicator 46 and a contact 72 connected to structure ground 22, and a power source 76 connected to the ground 22 and the fault indicator 46. In the embodiment of Fig. 1, an electrical contact between rotor ground 20 and the structure ground 22 is provided by a slip ring assembly 40 and a switch assembly 64 which is gauged with the switch assembly 50 and has a contact 66 connected to group 22 and a contact 70 connected to the contact 74 of the switch assembly 50. In operation the switch assemblies 50, 64 are in the operative position as shown in Fig. 1 so that the slip ring assemblies 30, 34 are connected in parallel between the lines 26a-26d and the fault indicator 46, with the slip ring assembly 40 providing an electrical ground between the grounds 20 and 22. With all the spar assemblies 12 at their normal internally pressurized condition, no current will flow from the power source 76 through the fault indicator 46 to ground. In the event of depressurization of one or more of the spar assemblies 12, the related one of the pressure transducers 24 will allow a current to flow from the power source 76 to activate the fault, indicator 46. The parallel slip ring assemblies 30, 34 create a redundancy of wiring between transducers 24 and the fault indicator 46 so that, if any part of the lines 26a-26d is broken, the system will still operate. A test position of switch assemblies 50, 64 is provided which when selected causes wiper blades 56, 62 to be connected to contacts 74, 70 to provide an immediate verification of the electrical continuity of the entire system. In another embodiment the slip ring assembly 40 and the switch assembly 64 are omitted, and the electrical contact provided by the rotating apparatus 18 between the grounds 20 and 22 is relied upon to provide the return current path during closure of a transducer.

Abstract: 304,486. Wiingaard, A. G. P. Jan. 30, 1928. Savings' boxes; coin action, weight and multiple.-A savings' clock in which the walls of the coin passage may be adjusted to take coins of different diameters and thicknesses, comprises a plate 1 carrying a fixed side wall 2, Figs. 1, 2 and 6, of the coin passage, the other side wall 11 being integral with a narrow end wall 10 and adjustably secured, for different thicknesses of coins, to the arm 5 of a lever 4, 5 by screws 12 in elongated slots 43. The other end wall 13 forms part of an angular plate 13, 14 adjustably secured by screws 45 and elongated slots to the fixed side wall 2. The lever 4, 5 is under the action of a spring 31 to cause the wall 10, in the absence of a coin, to approach the wall 13. When a coin is inserted, it moves the lever 4, 5 about its pivot 3 so that a pin 6 on the arm 4 moves a lever 7, 8 about a vertical pivot 42 and withdraws a spring on the arm 8 from the balance of the clock, which is thus set going. The coin rests on a projecting end 26, Figs. 1 and 7, of a double armed lever 24, 25 carried by the spindle 22 of a bell-crank lever 21, 20 the arm 20 of which is held by a spring 27 against the periphery of a notched exchangeable, disc 19 which is secured to a wheel 17 driven by the clockwork. When the end of the arm 20 enters the notch 18 in the disc 19, the end 26 is withdrawn to allow the coin to drop. A curved portion of the arm 24 enters a notch 15 in the side 11 to hold back a succeeding coin, if one be present. The end of the arm 21 engages behind a lug 37 on the side 11 and prevents it from returning to its original position under the action of the spring 31. When the rear edge of the notch reaches the arm 20 as shown in Fig. 1, the bell crank 20, 21 is moved to release the lug 37 so that the side 11 can move back to actuate the lever 7, 8 and stop the clock if another coin has not been inserted. A coin, however, held back by the arm 24 drops to the end 26 and prevents the side 11 from moving so that the clock continues to go for a further period.
