Title: Apparatus for minimizing solid particle erosion in stream turbines
Filed: 2013-05-20
Abstract: Solid particle erosion in a steam turbine is minimized by diverting through angled slots formed in appendages of outer rings of the diaphragms, a portion of the steam from the steam flow path thereby bypassing downstream rotating components. The slot through the first stage appendage lies in communication with a passage through a downstream outer ring of a following stage such that the diverted solid particle containing steam may be extracted from the steam flow path and passed to the feed water heater of the turbine. The slot in the second stage appendage diverts steam from between the first and second stages and about the second stage. Solid particle erosion in various regions, i.e., the trailing edge of the stator vanes, along the surfaces of the buckets and in the regions of the cover and its connection with the buckets as well as the sealing devices is thereby minimized.

Title: Mechanical clamping device
Inventor: POOT PIETER
IPC: B23Q3/06
Filed: 1979-12-21
Granted: 1982-12-09
Abstract: A mechanical clamping device, especially for clamping with high force of workpieces and tools, provided with clamping elements, characterised by an axial movable and helical rotatable conical wall (11, 21), against which rest similar bodies of revolution (12, 22), which are positioned on a changeable concentric circle of centre between two converging, concentric surfaces of revolution (13, 14, 23, 24), which are movable axially in respect of each other. Due to the extreme favourable behaviour of the rotating bodies of revolution (12, 22) which displace themselves at rotation in a helical way between the surfaces of revolution (13, 14, 23, 24), these surfaces are rolled and forced from each other. By this a favourable and equally distributed force transmission is obtained with a high degree of efficiency.
Patent DE-2966091-D1 (DE)
Inventor: BUROUGH IRVIN GEORGE
IPC: G01N21/35
Filed: 1979-10-01
Granted: 1983-09-29
Abstract: A gas analyzer and gas analyzing method are described of the non-dispersive infrared type wherein infrared energy is passed through a sample cell containing an unknown mixture of gas. The infrared energy passing through the cell is received by a detector and an electrical signal is produced representative thereof. A rotary filter wheel positions at least one filter in the path of the infrared energy, resulting in a pulsating detector output. The electrical signal is processed to produce an output indicating the concentration of the constituents of the gas mixture in the sample cell. Synchronization with the processed electrical signal is obtained by deriving synchronizing pulses directly from the electrical signal produced by the detector.

Title: Improvements in or relating to gear crimped polyester yarn
Inventor: WHALE WILLIAM EDWARD
IPC: D02G1/14
Filed: 1979-10-03
Granted: 1984-05-10
Abstract: Hitherto the commercial production of a gear crimped polyester yarn has not proved practicable due to extremely low bulk in the yarn and inadequate yarn mechanical properties. There is now provided a drawn gear-crimped polyester yarn with latent bulk the amount and nature of the bulk being such that the yarn has an initial crimp as defined of at least 1.5%, preferably of above 2%, and a mechanical crimp stability as defined of above 0%. The crimped polyester yarn may be produced by heating a drawable polyester yarn (9) having a birefringence in the range 32 x 10<-><3> to 125 x 10<-><3> inclusive, preferably 35 x 10-<3> to 125 x 10<-><3> inclusive, crimping the yarn by guiding it between the intermeshing teeth of a set of toothed wheels (11,19) such that the yarn is caused to follow a sharply zig-zag path, the toothed wheels being rotated at a sufficient speed such that the yarn is drawn by the tension so imparted to the yarn by the toothed wheels and subsequently forwarding the crimped yarn from the toothed wheels under a controlled tension within the range 0.15 to 0.50 g per decitex inclusive based on the decitex of the drawn polyester yarn.

Granted: 1985-03-28
Abstract: A clip or clamp is provided comprising a spiral strip (10) and a driving or actuating member (18) engageable with slots or slits (16, 17) in one end of the strip (10), whereby rotation of the driving member (18) about an axis normal to the surface of the strip (10) in one direction causes the spiral (10) to contract and rotation in the other direction causes the spiral (10) to expand. The driving or actuating member (18) is rotatably mounted in a housing (12) secured to the other end of the strip (10). The driving or actuating member (18) is provided with teeth or threads (23) which engage the slots or slits (16, 17) in the strip (10). The driving oractuating member (18) is slidable in the housing (12) between a first position in which the threads or teeth (23) engage the slots or slits (16, 17) in the strip (10), and a second position in which the threads or teeth (23) are disengaged from the slots or slits (16, 17), thereby providing a quick release of the clip, so that the first-named end of the strip (10) can be manually fed through the housing (12).

Title: Apparatus and method for articulatory speech recognition
Inventor: KELLET HENRY G
IPC: G10L15/00
Filed: 1982-08-04
Granted: 1989-04-20
Abstract: The parallel application of a plurality of vocal tract filters (12) is utilized in a speech recognition apparatus. Each of the filters in this bank of filters has a complex Fourier transfer function that is the reciprocal of a particular vocaltract transfer function corresponding to a particular speech sound. The speech elements identified are phoneme segments of short duration (typically 10 milliseconds), and correspond to phonemes only in the case of time invariant (sustainable) phonemes. In a preferred embodiment, it is assumed that the bank of inverse filters, when designed to correspond with the sustainable phonemes, is capable also of closely matching (in a piecewise fashion) the time-varying (transitional) phonemes. The input of each filter in the bank of filters is connected to the speech waveform input (30). The output of each filter is examined (18) to determine which output has the smallest absolute value. Generally, the filters are designed so that when a filter channel has the smallest output at a given time, there is usually present at the input of the filter bank at that time the waveform of the sound such filter was designed to detect. In a preferred embodiment, the apparatus determines (22) which filter's output is minimum in absolute value for the greatest total time over a given short interval of time, and the associated sound is specified as the sound present at the input.
