Title: Improvements in or relating to helicopters
IPC: B64C27/54
Filed: 1947-04-23
Abstract: 623,470. Helicopters. UNITED HELICOPTERS, Inc. April 23, 1947, No. 10880. Convention date, Feb. 21, 1944. [Class 4] A helicopter with coaxial contra-driven lifting rotors is provided with tilting or swash-plate systems for cyclic pitch control of the rotor blades, the systems being interconnected for simultaneous adjustment along the axis of the rotors for differential collective pitch variation for steering purposes, while a further control system effects additional adjustment of the blades of one rotor and is so connected to the swash-plate systems as to effect simultaneous collective pitch variation for height control. General arrangement.-In the form illustrated, hollow coaxial shafts 42, 38 carry the upper and lower rotors 19, 20 respectively, and are driven by a transmission shaft 32, incorporating a clutch, through bevel gearing 34, 35, 36. Cyclic pitch control.-The direction of flight of the aircraft is controlled by a column 24 carrying a hand wheel 23 jointly operating cables 140, 146, 151 connected to a tilting ring 62 mounted on a ball joint 64 and connected to the pitch control arms 71, 72 of the lower rotor 20 by vertical links 67, 68. The tilting ring 84 controlling the pitch of the upper rotor blades 19 is mounted on transversely disposed pivots 82, and is connected to the links 67, 68 by members 75, 76, 77, 78 and to the upper rotor pitch arms 111, 112 by linkages 88, 89, 103, 104, 107, 108. Differential collective pitch control.-The rudder bar 28 is connected to an arm 122 carried by a threaded sleeve 126, rotation of which causes vertical movement of the ball joint 64 and hence of the rings 62, 84, to impart equal and opposite pitch variations to the respective rotors and thus unbalance their reaction torques. Simultaneous collective pitch control.-A control lever 26 operates two arms 114, 121 simultaneously, the latter being carried by a threaded sleeve 124 engaging the sleeve 126, so that rotation of the arm 121 effects vertical movement of the tilting rings 62, 84 to vary the rotor pitches equally, but in opposite senses. The arm 114 is carried by a threaded sleeve 116, rotation of which moves an axial shaft 44 vertically, the upper end of the shaft being connected to the links 103, 104 of the upper rotor pitch control mechanism by a pivot 96. The linkages are so arranged that movement of the shaft 44 superimposes on the upper rotor a pitch variation of twice the magnitude, but of opposite sense, to that imposed by the movement of the tilting ring 84, so that operation of the lever 26 results in equal variations of the respective rotor pitches.

Title: Time division multiplexing
IPC: G06F13/22
Filed: 1970-03-06
Abstract: 1308062 Multiplexing systems INTERDATA Inc 6 March 1970 [6 March 1969] 10899/70 Heading H4P A multiplexer has means for controlling groups of data lines and means for loading and unloading data including a clock providing signals a predetermined multiple of bit rate. An automatic processor controls input serial data from each line through a common bus in parallel form into and out of a memory. A fixed programmer controlls the processor, a memory, data line means and clock, and has instruction means to detect the start of each character and control the strobing of input data stored in the memory. The fixed programme can generate a mask dependent on the number of bits in a character, which mask is continually shifted into integral assembly registers as the character is being assembled, with detection of a particular bit to indicate completion. Multiplexer control unit MCU 14 includes a clock and control 14b operating at seven times the bit rate of the terminals 16a-16ff, e.g. teleprinters which may feed directly through data line units 11a-11f or indirectly through data sets and telephone lines (see Fig. 1, not shown) a scanner 14c coupled with counters (not shown) controlling the line units 11a &c. so that data flows into a bus (24, Fig. 1) in parallel. A read buffer 30 temporarily stores serial input data from devices 16a &c. one register to each device. A read only memory (RAM 20) has sections 20a-20d which perform the function of assembly and dissembly of each serial data stream and which feed into and receive from assembly registers 32, 32a transforming serial data into parallel characters. An individual assembly register and individual transfer buffers are also assigned to each device 16a &c. Each dissembly register is alternately switched by device 39, i.e. while data is being dissembled in one set of registers the other is being filled. Write buffer 36 temporarily stores dissembled data transmitted to devices 16a &c. In the core memory each phase of the clock 0-6 is assigned a block 46a-46g associated with one memory bit assigned per device 16a &c. selected by phase character 44. Blocks 46a-46g form separate parts of a core (18) which also includes assembly registers 32. The sum activity block 48 monitors the state of each device. A flow chart is illustrated in Figs. 3A-3F (not shown).

Abstract: 668,920. Control systems for heating resistances. SHACKLOCK, Ltd., H. E. May 9, 1950 [May 17, 1949], No. 11551/50. Class 38 (iv). [Also in Group XI] An electric range comprising oven heating elements and hot plates is provided with an oven booster element 14 and switch control means for diverting to the booster element current supply normally available for one or more of the hot plates which is or are automaticallv switched off when the booster is switched on. Depressing a push button 4 initially causes a switch 16 to close. An electromagnet 21 is thus energized from power lead 12 and draws down contact bar arm 6, thereby closing contacts 9 controlling the booster current and separating hot plate control contacts 10 which are mounted on a flexible portion 7 of the contact bar. When the contacts of a double pole thermostat 22 break, the electromagnet and ordinary oven circuits are broken and the contact bar is drawn to its normal position by a spring 11. Current supply to hot plate lead 13 is thus remade through contacts 10 and booster current supply is broken at contacts 9. The re-making of the thermostat contacts when the oven heat falls causes the normal oven element 24 only to operate, the booster being out of operation and the hot plates being unaffected by the thermostat operation.
