Abstract: 1,213,347. Rotor blade fixing. UNITED AIRCRAFT CORP. June 26, 1968 [Aug.16, 1967], No.30354/68. Heading F1T. To reduce vibration of the blades of a compressor of fan rotor in a gas turbine engine each blade is mounted on the rotor by a pin passing through holes in the blade root and in the rotor with clearance to permit rolling of the pin and each blade differs from an adjacent blade in the diameter of the pins and/or holes and/or in the distance of the pin axes from the rotor axis. Thus each blade has a different natural frequency to an adjacent blade. In one embodiment, the blades are mounted on the rotor 74 in similar groups of three, e.g. 50 to 52 or 53 to 55, and the pins 60 to 62 or 63 to 65 in each group are at different distances from the rotor axis. Alternatively, the blades may be mounted on the rotor at only two different radii so that every other blade is on the same radius. The different radii can be combined with, or replaced by, different diameter pins and/or holes.

Title: An oriented,semicrystalline polymer product and method and apparatus for producing such product
Inventor: AUSTEN A
IPC: B29C48/09
Filed: 1979-09-07
Abstract: A thick-walled, seamless, rigid non-porous conduit (Y) having a substantially uniform wall thikkness which is not less than about 0.5 percent of the outside diameter consisting essentially of an oriented crystalline thermoplastic polymer characterized by a structure comprised of radially compressed discrete, platelet-like spherulitic crystalline aggregates (A!) and having a combination of good ultimate tensile strength and low temperature tensile impact strength. The conduit is fabricated by solid state hydrostatic extrusion of a substantially non-oriented semi-crystalline thermoplastic polymer preform (X) which may contain up to about60 weight percent filler. The polymer is substantially simultaneously elongated in both circumferential and axial directions by compressive forces with the circumferential elongation being at least 100 percent. The apparatus used to produce the product is a hydrostatic extrusion press which includes an annular orifice in which the thermoplastic polymer is elongated substantially simultaneously circumferentially and axially with the circumferential elongation being at least 100 percent. Means for maintaining the rigidity of tooling and the hydrostatic extrusion fluid pressure while providing a film of the fluid on the preform for lubricity are provided in the apparatus. A sheet (F) substantially uniform in thickness and having substantially the microstructure and properties of the conduit and excellent drawability may be made from the conduit by slitting and heat deformation. Articles of manufacture may be made by solid state deformation processing of the conduit or the sheet, such as vacuum drawing.

Title: Device for interfacing a pcm t.d.m. line to an exchange
Inventor: ZEITRAEG R
IPC: H04Q11/04
Filed: 1980-09-11
Abstract: A pulse coded time division multiplex (PCM) telecommunication system has two non-synchronous clock pulse trains for controlling information transfer and switching operations, respectively. In a circuit arrangement for compensating phase differences resulting from deviations between both clock pulse trains there is arranged an intermediate store for externally controlled buffering of PCM words for half of a pulse frame and connected thereto a buffer store for internally controlled buffering of PCM words for a full pulse frame. The intermediate store is designed for two modes of operation under control of the external clock pulse train. In an active mode during one cycle at first a stored PCM word is read out and is then replaced by a new PCM word. In the second mode the same PCM word first is temporarily buffered and immediately read out thereafter. Change of operation is controlled by a control unit monitoring addresses for alternate read operations and write operations of the buffer store of a minimum off-set of selected addresses to obtain by skipping of half of a pulse frame sufficient off-set without continuous uncontrolled slippage losses.

Abstract: 1. A circuit arrangement for telecommunications systems, in particular PCM telephone exchange systems, with a duplicated exchange clock supply arrangement (CCG', CCG") in which the respective first of the two exchange clock generators supplies an exchange clock signal (T', T") which is generated independently of the respective other exchange clock generator, and the respective other (slave) exchange clock generator supplies an exchange clock signal which is synchronised so as to be at least approximately in phase with the exchange clock signal supplied by the respective first (master) exchange clock generator, and in which each of the two exchange clock generators, servo-synchronised by a supplied master clock signal (M', M"), generates an intermediate clock signal (H', H") with a clock period which at the maximum is equal to the maximum permissible phase difference between the exchange clock signals supplied by the two exchange clock generators, and in which, in each of the two exchange clock generators, the intermediate clock signal is supplied to a respective frequency divider (BKU, U) for the acquisition of the exchange clock signal, and in which the respective slave exchange clock generator compares its exchange clock signal with the exchange clock signal of the respective master exchange clock generator (PD) and when a phase difference is established which exceeds a limit value in the order of one intermediate clock period (h) by means of a regulating device in the case of a lagging slave exchange clock signal shortens-and in the case of a leading exchange clock signal lengthen-one half period of the slave exchange clock signal by the length of one intermediate clock period, and in which the exchange clock signal supplied by the respective master exchange clock generator is monitored and in the event of the failure thereof the regulating device of the hitherto slave exchange clock generator is disconnected, whereby the hitherto slave exchange clock generator now becomes the master exchange clock generator whose exchange clock signal is now supplied to the hitherto master exchange clock generator which has now become the slave exchange clock generator, characterised in that when it establishes a leading or lagging of the initially slave exchange clock signal the regulating device (UVR) of the initially slave exchange clock generator lengthens or shortens respectively the half period of the exchange clock signal supplied by itself with a time delay which is at least equal to the time interval required to disconnect the regulating device of the slave exchange clock generator in the event of the failure of the master exchange clock signal.
